Abstract

It is possible to know the occurrence of an earthquake even in a room where an emergency warning device is not installed or a place where the FM broadcast reception environment is not good by cooperation with an alarm device.
An emergency warning device 25 detects an emergency earthquake information signal including an emergency earthquake warning signal or a tsunami warning signal by broadcasting, and sends a device event signal indicating the earthquake notification or tsunami notification together with the notification to a resident police device 10-1 to 10-10. Send to -6. The home alarm devices 10-1 to 10-6 detect and notify a fire in the warning area, detect a sensor failure or a low battery failure, and notify the emergency warning device 25 of an event signal indicating a fire or a failure. When the device event signal indicating the earthquake notification or the tsunami notification is received from the emergency warning device 25, the information indicating the emergency earthquake warning or the tsunami warning is notified. In the emergency warning device 25, a fault warning is output in such a way that the resident alarm detecting the fault is identified based on the identification information of the transmission source.

Description

The present invention relates to an alarm system, an alarm linkage method, an emergency alarm device, and an alarm device that output an earthquake early warning or an earthquake early warning to an alarm device that detects an alarm such as a fire or a gas leak.

  Conventionally, alarm devices that detect and warn of abnormalities such as fires and gas leaks in homes have become widespread. Of these, residential fire alarms are referred to as residential alarms.

  In such a house alarm device, the sensor unit and the alarm unit are integrally provided in the house alarm device, and when a fire is detected from the detection signal of the sensor unit, a fire alarm is output from the alarm unit by a voice message or the like. In addition, since it is possible to monitor and warn the fire with a resident alarm alone without the need for dedicated receiving equipment, it is easy to install and inexpensive, and has become widespread due to the obligatory installation in ordinary houses. .

  In addition, by communicating between multiple home alarms, when a fire alarm is issued by any home alarm, another home alarm system is also proposed in which other home alarms also issue an alarm. Has been.

  In such a home alarm system, when a fire is detected by the home alarm, the source home alarm that detected the fire is, for example, “Please check that the Woo Woo Fire Alarm has been activated”. A voice message is output. When an alarm is issued by the house alarm, the alarm is stopped by operating an alarm stop switch provided in the house alarm.

  In recent years, as a result of efforts to reduce the power consumption of residential alarms, a long battery life of, for example, 10 years or more is guaranteed, and no battery replacement is required during that period. When battery life (remaining capacity) decreases when battery life is approached after long-term use, a battery warning notice (hereinafter referred to as “low battery failure alarm”) is output to prompt battery replacement. ing.

  After the start of the output of the low battery failure alarm (after the battery voltage drop is detected), it is only necessary that the intermittent low battery alarm output can be continued for a predetermined time (for example, 72 hours) or longer. If the battery is replaced within the range, there is no problem. In general, the low battery alarm is not a highly urgent alarm like a fire alarm because it is designed to allow normal monitoring operation during this period.

  Therefore, as a low battery failure alarm, conventionally, in order to avoid the acoustic alarm output from nighttime to early morning, which is a sleeping time, as much as possible, a battery exhaustion alarm is output from the speaker after a predetermined time has elapsed after detecting a decrease in battery voltage. When a fire alarm (Patent Document 1) or the battery voltage has dropped below a predetermined voltage, a power lamp or the like is lit or blinked to notify the battery drop, and a switch operation is performed in this state. A battery-type alarm device (Patent Document 2) is known that outputs a voice message including content for prompting battery replacement from a speaker.

  If the battery voltage drop is detected while the user is absent for a long period of time, the low battery failure alarm will be output continuously for as long as possible with the minimum necessary power consumption. In addition, an alarm device has also been proposed in which a battery is surely noticed and a battery operation is known by a switch operation (Patent Document 3).

  In the case of a conventional house alarm, if the alarm stop switch is operated in the normal monitoring state, the self-inspection such as the presence or absence of a sensor, detection circuit, voice notification circuit failure, sensitivity abnormality due to contamination, etc. is executed, and the inspection result Is informed. If there are no abnormalities, the inspection result is reported by outputting a voice message that includes, for example, “normal”, and if a sensor failure is detected, a voice message such as “pick failure” is output. Do.

  In the interlocked house alarm system for such low battery fault alarms and sensor fault alarms, the fault alarm indicating the source of the interlock is output by the house alarm that detects the fault, and the destination of the interlock is indicated by the other house alarms. A fault alarm is output.

  On the other hand, as an earthquake warning system that notifies earthquake information using TV broadcasting, FM broadcasting, and AM broadcasting, emergency warning broadcasting is performed when a large-scale disaster such as an earthquake occurs or when a tsunami warning is announced. There is also an emergency earthquake bulletin that announces predictions for areas where strong shaking is expected before the shaking arrives in the event of an earthquake.

  Emergency warning broadcasts are broadcast via TV, FM and AM broadcasts when a Tokai earthquake warning declaration is issued, when a tsunami warning is announced, or when an evacuation instruction is issued by the governor or the head of the local government. An emergency alert signal is transmitted to automatically turn on the receiver, and the emergency alert broadcast is reproduced and output.

  In addition, the earthquake early warning will be announced at an estimated maximum seismic intensity of 5 or less, and an earthquake early warning signal will be transmitted by TV, FM and AM broadcasts, and a serious disaster will occur in areas where strong shaking is expected due to earthquake motion Warning that there is a risk.

  Emergency warning devices that function as dedicated receivers in response to such emergency warning broadcasting and earthquake early warnings have been put into practical use and are widely used.

  For example, in an emergency warning device corresponding to an earthquake early warning, for example, a specific FM radio broadcast is selected and is in a reception standby state. "Please be wary of strong shaking" twice, for example, the first chime sound is analyzed, the earthquake early warning signal is detected, the broadcast playback operation is started, and the automatic sound following the chime sound Is output from the speaker at the set volume to notify the occurrence of an earthquake.

  Further, in the case of an emergency warning broadcast of analog broadcasting, the emergency warning device corresponding to the emergency warning broadcast detects an FSK signal which is an electronic sound (piropiro sound) in the audible range first transmitted as a start signal. In such a case, a broadcast reproduction operation is started to receive and reproduce emergency warning broadcasts such as tsunami warnings.

Furthermore, an emergency warning device corresponding to both emergency earthquake warning and emergency warning broadcasting has been put into practical use.

  However, in such a conventional emergency warning device, the emergency earthquake warning and tsunami warning can be heard only within the range where the sound from the emergency warning device can be heard, and the emergency warning device is installed for each room. Although it is necessary, there is a problem that the cost is high and installation spaces must be secured in various places.

  In addition, since it is basically a broadcast receiver, when receiving FM broadcasts or AM broadcasts, radio wave conditions may not be received with sufficient strength depending on the room. Even if installed, it may not function effectively.

  On the other hand, in an interlocked house alarm system that links multiple house alarms, it is easy to install and cost-effective because the fire alarm can be monitored with a single house alarm without the need for dedicated receiving equipment. However, there is a merit that it can be made cheaper. However, if a house alarm detects a fire and outputs an interlocking source alarm, and another house alarm outputs an interlocking destination alarm, any of the house alarms will fire. There is a problem that it is difficult to determine whether it is detected, and it is difficult to grasp the situation of the entire home alarm.

  This problem also applies to low battery failure alarms and sensor failure alarms, etc., where a certain resident alarm detects a failure and outputs a failure alarm indicating the linkage source, while another resident alarm outputs a failure alarm indicated by the linked destination. When output, there is a problem that it is difficult to determine which house alarm detects the failure and it is difficult to grasp the failure state of the entire house alarm.

The present invention makes it possible to know the occurrence of an earthquake even in a room where an emergency warning device is not installed or a place where the reception environment of broadcast radio waves is not good due to cooperation with the alarm device and An object of the present invention is to provide an alarm system, an alarm linkage method, an emergency alarm device, and an alarm device that have a function as a receiver so that the status of an alarm device that has failed can be easily grasped.

  FIG. 1 is an explanatory view showing an installation state of an alarm system according to the present invention for a house. In the example of FIG. 1, a wireless dwelling alarm (for dwelling) that detects and alerts to fire in each of the warning areas of the living room, kitchen, children's room, master bedroom, and staircase provided in the house 24. Fire alarm devices) 10-1 to 10-6 are installed, and an emergency alarm device 25 is installed in a place where the living room has a good FM radio wave environment. Here, the emergency warning device 25 corresponds to the earthquake warning device described in the claims.

  The home alarm devices 10-1 to 10-6 have a function of transmitting and receiving event signals to each other wirelessly, and monitor each corresponding monitoring area in each part of the house. Here, six units monitor the fire of the entire house. Is going. If a fire has occurred in the kitchen of the house 24, the home alarm device 10-2 detects the fire and starts an alarm. Detecting this fire and initiating an alarm is referred to as “reporting” at the home alarm.

  When the Dwelling Unit 10-2 issues a warning, the Dwelling Unit 10-2 functions as a linkage source, and a fire is fired against the other Dwelling Units 10-1, 10-3 to 10-6 that are linked. An event signal (fire event signal) is transmitted by radio. When the other home alarm devices 10-1, 10-3 to 10-6 have effectively received an event signal indicating the occurrence of a fire from the home alarm device 10-2 of the interlocking source, the interlocking destination is indicated by an alarm sound and an alarm display. The alarm action is performed.

  Here, “effective reception” detects that this event signal has been received effectively when the group code included in the received event signal matches the group code registered in the memory. Moreover, the transmission source code | cord | chord is included in the event signal transmitted from the residence police device 10-1 to 10-6 as identification information which shows the residence police device of a transmission origin, for example. In addition, the residence police device 100 which received the event signal effectively performs relay transmission of the event signal as needed.

  The self-events detected by the home alarm include not only the above-mentioned fire occurrence but also fire recovery, alarm stop operation, etc., and the effective reception of various event signals from other alarm devices and the emergency alarm device 25 is also included. It is. These will be described later.

  As an alarm operation of the home alarm device 10-2 that is the link source, for example, an alarm sound by a voice message such as “Please confirm that the Woo Woo fire alarm has been activated” is output. On the other hand, in the interlocked home alarm devices 10-1, 10-3 to 10-6, an alarm sound is output by a voice message such as “Please confirm that another fire alarm has been activated”.

  Moreover, as an alarm display accompanying the alarm of the home alarm device 10-2 which became the interlocking | linkage origin, LED is lighted, for example. On the other hand, in the interlocking destination home alarm devices 10-1, 10-3 to 10-6, the LED is blinked. As a result, the alarm display by the LED in the interlock source alarm and the interlock destination alarm can be distinguished.

  The interlocking source LED may be blinking and the interlocking destination LED may be blinking, or the same LED may be blinking or blinking or lit for both the interlocking source alarm and the interlocking destination alarm. Further, for example, a red LED and a yellow LED may be provided, and the two-color display may be performed such that the interlocking source drives the red LED and the interlocking destination drives the yellow LED. Of course, a two-color LED capable of emitting both red and yellow by combining two LEDs can be adopted.

  When the alarm stop switch is operated in a state in which the house alarm devices 10-1 to 10-6 are emitting an alarm sound, the alarm sound and the alarm display stop process are performed.

  At this time, for example, in the case where an alarm stop operation is performed in the home alarm device 10-2 that is the interlocking source, alarms (alarm sound output and / or alarm display output) of all the home alarm devices 10-1 to 10-6 ) And the alarm stop operation is performed in any of the interlocking destinations of the residential police 10-1, 10-3 to 10-6, the alarm of the residential police 10-2 does not stop The alarms of the residential alarm devices 10-1, 10-3 to 10-6 are stopped. In addition, in the following description, when calling the housing alarms 10-1 to 10-6 without distinguishing them, they are referred to as the housing alarms 10.

  The home alarm device 10 detects a low battery failure from a drop in the voltage supplied from the battery power source and outputs a low battery failure alarm indicating the interlock source (failure source). An event signal indicating a low battery failure (low battery failure event signal) is transmitted to a low battery failure alarm indicating a linkage destination (failure destination).

  The low battery failure alarm indicating the link source, for example, outputs “Pattern is out of battery” several times from the speaker of the home alarm 10 and turns on the LED, for example, and then “Pattern is exhausted” at regular intervals. The process of outputting the sound and displaying with the LED multiple times is repeated. The low battery failure alarm indicating the link destination, for example, continuously outputs “Since another alarm device is out of battery” from the speaker of the home alarm device 10 multiple times and blinks the LED, for example. Make a sound output such as “Beep another alarm is out of battery” and blink by LED.

  Further, the home alarm device 10 detects a sensor failure and outputs a sensor failure alarm indicating a link source (failure source), and an event signal indicating the sensor failure (sensor failure event signal) to the other home alarm devices and the emergency alarm device 25. ) To output a low battery fault alarm indicating the link destination (failure destination).

  The sensor failure detected by the home alarm device 10 includes the presence or absence of a sensor, detection circuit, audio notification circuit failure, sensitivity abnormality due to contamination, etc., and the home alarm device 10 performs self-inspection for detecting the sensor failure. Is executed in the background and the inspection result is stored in the memory.

  Moreover, when operating the alarm stop switch that functions as a check switch in a normal state, the home alarm 10 refers to the result of the self-check that is executed in the background and stored in the memory, and notifies normality or a failure.

  When the home alarm device 10 detects a sensor failure, it outputs, for example, “It is a pin failure” continuously from the speaker as a failure alarm sound indicating the link source (failure source), and turns on the LED, for example, for a certain period of time thereafter. Each time, the sound output of “It is a pin failure” and the display by lighting the LED are repeated several times.

  Further, when the home alarm device 10 detects a sensor failure, the home alarm device 10 transmits an event signal indicating the sensor failure (sensor failure event signal) to another home alarm device or the emergency alarm device 25, for example, “a separate alarm device is detected. A warning sound such as “Failure” or “Beep alarm is faulty” is output and a display different from the interlock source, for example, blinking.

  The emergency warning device 25 detects an emergency earthquake warning signal or a tsunami warning signal as an emergency earthquake information signal transmitted from a broadcasting facility as its own event, reproduces and outputs it, and also displays an emergency earthquake information notification to the resident alarm 10. As an event signal, an emergency event warning notification (hereinafter referred to as “earthquake notification”) and a device event signal indicating a tsunami notification are transmitted. Events detected by the emergency warning device 25 include operation of the operation unit, effective reception of event signals indicating fires, faults, and the like in addition to the above-mentioned emergency earthquake warning signal reception.

  Emergency earthquake information broadcasts received and reproduced by the emergency warning device 25 include emergency earthquake warning (EEW) and emergency warning broadcasting (EWS). The earthquake early warning is a warning issued by the Japan Meteorological Agency with an estimated maximum seismic intensity of less than 5 for the general public, and warns that there is a possibility of serious disasters due to earthquake motion to areas where strong shaking is expected Broadcast. For example, “Earthquake early warning (2 times chime sound). Watch out for strong shaking” is repeated twice. For example, the emergency warning device 100 analyzes the first chime signal to detect an emergency earthquake warning signal and switches from the reception standby state to the reproduction operation, and “Emergency earthquake warning. Be wary of strong shaking.” Output at the set volume.

  The emergency warning broadcast is an alarm that is issued when a disaster such as an earthquake occurs or when a tsunami warning is announced, and automatically switches on a standby television or radio receiver. The first type start signal, the second type start signal, and the end signal are used for the start and end of the emergency warning broadcast. The first type start signal is transmitted when a warning declaration of the Tokai earthquake is announced, or when an evacuation instruction is issued from the governor or the head of the local government, and automatically turns on the receiver. Also. The type 2 start signal is sent only when a tsunami warning is announced, and the same automatically turns on the receiver. The end signal is transmitted a predetermined time after the transmission of the first type or second type start signal, and automatically turns off the receiver. In addition, a test signal is transmitted at a predetermined time, for example, once a month to check the operation of the receiver. This test signal is the same as the end signal, and if only the end signal is received, the receiver operates normally. Check if it works.

  In the following description, detection of the second type start signal by emergency alert broadcasting is referred to as detection of a tsunami warning signal. Moreover, in this embodiment, although it corresponds to the tsunami warning signal by the type 2 start signal in the warning earthquake early warning and the emergency warning broadcast, the emergency warning by the type 1 start signal is excluded, but it is necessary. You may add according to.

  When the emergency warning device 25 is installed and the apparatus warning signal indicating the earthquake notification is effectively received from the emergency warning device 25, the residential alarm device 10 of the present embodiment transmits a voice message as information indicating the earthquake notification a predetermined number of times ( (Including one time) or output repeatedly for a predetermined time. As a voice message indicating information indicating an earthquake notification, for example, “Peep emergency earthquake early warning. Be wary of strong shaking”.

  In addition, when the device alarm signal indicating the tsunami notification is effectively received from the emergency warning device 25, the resident alarm 10 outputs the information indicating the tsunami notification for a predetermined number of times (including one time) or for a predetermined time. . For example, “Peepy Tsunami Warning has been issued. Please do not approach the coast and evacuate to the hill” is output as a voice message indicating information indicating the tsunami notification.

  Moreover, when the emergency alarm device 25 receives the fire event signal from the home alarm device 10, it determines the home alarm device that detected the fire based on the transmission source code included in the fire event signal, and any of the home alarm devices detected the fire. An audible alarm sound is output. The fire alarm sound of the emergency warning device 25 is, for example, a voice message such as “Please confirm that the Woo Woo No. 1 fire alarm has been activated” or “Woo Woo the fire alarm in the living room has been activated” .

  In addition, the emergency warning device 25 displays a fire by sounding, flashing, or blinking the LED together with a fire alarm sound, and also displays information such as a house alarm number indicating a house alarm detecting the fire and a room name indicating an installation location. And displayed on a liquid crystal display.

  The emergency alarm device 25 is connected to the fire alarm system in the fire alarm system using the interlocking type home alarm devices 10-1 to 10-6 by the notification indicating the home alarm device detecting the fire by the emergency alarm device 25. It can be used as a device that plays a role, and it becomes possible to collectively manage the fire monitoring statuses of the residential alarm devices 10-1 to 10-6.

  Further, when the emergency warning device 25 effectively receives the low battery failure event signal from the home alarm device 10, the emergency warning device 25 detects the home alarm device that has determined the low battery failure based on the transmission source code included in the low battery failure event signal, and An alarm sound is output with a voice message indicating whether the alarm has detected a low battery failure. As the low battery failure alarm sound of the emergency alarm device 25, for example, a voice message such as “Pi No. 1 fire alarm is out of battery” or “Pi living room fire alarm is out of battery” is used.

  The emergency warning device 25 displays a low battery failure by turning on, blinking, or blinking an LED together with a low battery failure alarm sound, and also displays a house alarm number indicating a housing alarm that has detected a low battery failure and a room name indicating an installation location. Such information is displayed with an indicator or a liquid crystal display.

  The emergency alarm device 25 is notified by the emergency alarm device 25 of the fire alarm system using the interlocked residence alarm devices 10-1 to 10-6 by the notification indicating the home alarm device detecting the low battery failure. It can be used as a device that plays the role of a machine, and it becomes possible to collectively manage the low battery failure of the mortgages 10-1 to 10-6.

  Further, when the emergency alarm device 25 effectively receives, for example, a sensor failure event signal from the home alarm device 10 that has performed the self-inspection, the emergency alarm device 25 detects the home alarm device that has determined the sensor failure based on the transmission source code included in the sensor failure event signal, An alarm sound is output with a voice message indicating which housing alarm has detected a sensor failure. The sensor failure alarm sound of the emergency warning device 25 is, for example, a voice message such as “Pi No.1 fire alarm is out of order” or “Pimber fire alarm is out of order”.

  The emergency warning device 25 displays a sensor fault by lighting, blinking, or blinking the LED together with a sensor fault alarm sound, and also information such as a house alarm number indicating a house alarm that detects the sensor fault and a room name indicating an installation location. Is displayed with an indicator or a liquid crystal display.

  The fire alarm in the fire alarm system using the interlocked house alarm devices 10-1 to 10-6 by the notification indicating the house alarm device detecting the sensor failure by the emergency alarm device 25. Therefore, it is possible to collectively manage failures such as sensor failures of the residential alarm devices 10-1 to 10-6.

  Here, in the resident alarm 10, after detecting a low battery failure or a sensor failure and outputting a failure alarm, the failure alarm sound and the failure display are repeated a plurality of times at regular intervals. In this case, an event signal indicating a low battery failure or a sensor failure may be transmitted so that the emergency alarm device 25 repeatedly outputs a failure alarm sound and a failure display multiple times.

  Since the emergency warning device 25 is operated with a commercial power supply, after receiving an event signal indicating a low battery failure or a sensor failure and outputting a failure warning with a failure warning sound and warning display, the failure warning display is performed. May be continued, and the failure alarm display by the alarm operation may be stopped.

  Moreover, when the emergency warning device 25 is installed in the same place as any of the residential alarms 10, the earthquake notification and the tsunami notification are output from both and it becomes difficult to hear. Therefore, in the present embodiment, the prohibition mode for prohibiting the output of earthquake notification and tsunami notification to the resident alarm 10 can be set by the operation of the mode switch, and the same place as the emergency warning device 25 (alarm and notification range overlap). By setting the prohibit mode for the house alarm installed in the place where the earthquake is to occur, even if a device event signal indicating earthquake notification or tsunami notification is received from the emergency warning device 25, the earthquake notification or tsunami notification is indicated. Do not output information.

  The prohibit mode setting function can be used in the same way even when a plurality of residential alarms are installed in the same place.

  As described above, the prohibit mode setting function may be provided on the side of the house alarm, but in general, it is assumed that the house alarm 10 has a larger number of installed units than the emergency alarm device 25. In consideration of the overall cost of the equipment, the emergency alarm device 25 may be provided. In this way, it is not necessary to install the prohibit mode setting function in the residential alarm device 10 having a large number of installed units, the overall cost of the system equipment can be suppressed, and the emergency warning device can be used even when checking the presence or absence of the prohibit mode setting. It is effective to prevent the operation from becoming complicated.

  Moreover, when considering together the duplication alerting | reporting of the emergency alarm device 25 and the housing alarm 10, and the duplication alerting between housing alarms, the prohibition mode setting function is provided in both the housing alerting device 10 and the emergency alerting device 25, You may enable it to set each according to installation conditions. Naturally, at this time, when a plurality of emergency warning devices 25 are installed at the same place, it is possible to set so as to avoid the redundant notification between the emergency warning devices.

  Of course, even in an installation situation in which alarms and notification sounds are output in duplicate, it is not always necessary to use the prohibit mode setting, and it is appropriately selected and set by the user's judgment.

  Further, in FIG. 1, when a fire is detected and alarmed by the home alarm device 10-2, the other home alarm devices 10-1, 10-3 to 10-6 and the emergency alarm device 25 indicate a fire occurrence. A route for transmitting an event signal is shown as an event communication route 11a, and a route for sending a device event signal indicating an earthquake standing or tsunami notification from the emergency warning device 25 is shown as a device event communication route 11b. In addition, although the event signal or apparatus event signal received by the residence guards 10-1 to 10-6 is respectively relayed to other residence guards, the communication path is omitted.

The alarm system of the present invention may be configured by mixing these various alarm devices.

  FIG. 3 is an explanatory view showing the appearance of an embodiment of the emergency alert device according to the present invention, taking the case of receiving FM broadcast as an example. In the emergency alarm device 25 of FIG. 3A, a monitoring lamp 112 and an alarm lamp 114 are provided on the right side of the front surface of the box-shaped housing, and operate with a commercial AC power source, for example. The monitoring light 112 is lit in green in an emergency earthquake information broadcast reception standby state including an emergency earthquake warning and a tsunami warning broadcast, indicating that it is in a normal operation state, and reception of the selected FM broadcast is unstable. Then, it blinks, and if it is not correctly tuned to the frequency of FM broadcast, it is turned off. The alarm lamp 114 is lit red, for example, when receiving and reproducing the emergency earthquake information broadcast.

  An FM antenna 75 and an antenna 85 for a home alarm are installed behind the box-shaped housing. Furthermore, an acoustic hole (not shown) is provided on the upper surface of the box-shaped housing, and outputs sound from a built-in speaker.

  A liquid crystal panel 116 is provided as a display unit on the left side of the front of the box-shaped housing, and when a fire event signal is effectively received from the resident alarm 10, a fire is detected based on a transmission source code included in the fire event signal. The alarming alarm is detected, and the number indicating the detected alarm and the area indicating the installation location (such as the room name) are displayed.

The liquid crystal panel 116 also displays a frequency at the time of channel selection operation.

  FIG. 3B is an explanatory view showing the appearance of another embodiment of the emergency alert device according to the present invention. The emergency warning device 25 of FIG. 3 (B) is provided with a house warning device indicator lamp 118 in which, for example, eight LEDs are arranged instead of the liquid crystal panel 116 provided in FIG. It is characterized by that.

  For example, house alarm numbers 1 to 8 are displayed on the house alarm indicator lamp 118, and the relation between the source code of the house alarm and the house alarm number is registered in the table to receive from the house alarm. The LED having the number corresponding to the transmission source code included in the event signal indicating the fire is turned on or blinked to indicate a resident alarm that detects a fire, a low battery failure or a sensor failure.

  FIG. 4 is a block diagram showing an embodiment of a residential alarm provided in the alarm system of FIG. This is an example, and the separation and integration of each function can be performed arbitrarily. Each part or all of each function may be executed by software (program) or may be executed by hardware.

  In FIG. 4, the house guard is shown for the house guard 10-1 installed in the living room, but the other house guards 10-2 to 10-6 have the same configuration.

  The home guard 10-1 includes a processor 28 known as a one-chip CPU. For the processor 28, a wireless communication unit 30 including an antenna 31, a memory 32, a sensor unit 34, a notification unit 36, an operation unit 38, and A battery power source 40 is provided.

  The wireless communication unit 30 is provided with a transmission circuit 42 and a reception circuit 44 so that event signals can be transmitted and received wirelessly between the other residential alarm devices 10-2 to 10-6. The device event signal can be received. As the wireless communication unit 30, in Japan, for example, STD-30 (wireless equipment standard of a low power security system wireless station) or STD-T67 known as a standard of a specific low power wireless station of 400 MHz band. It has a configuration that conforms to the standard for specific low-power radio station telemeters, telecontrol and data transmission radio equipment.

  Of course, when the wireless communication unit 30 is used outside Japan, the wireless communication unit 30 has contents compliant with the standard of the assigned wireless station in that region.

  The antenna 31, the transmission circuit 42, and the transmission processing unit 60 are collectively referred to as a transmission unit, and the antenna 31, the reception circuit 44, and the reception processing unit 62 are collectively referred to as a transmission unit.

  The transmission of the event signal in the transmission circuit 42 of the wireless communication unit 30 includes an operation of transmitting an event signal for a predetermined time T1, for example, T1 = 3 seconds, with a pause of a predetermined time T2, for example, T2 = 2 seconds. Repeated 4 times. This T1 = 3-second transmission and T = 2-second pause comply with the standard of a specific low-power radio station. In the transmission operation of T1 = 3 seconds, for example, 2.8 seconds from the beginning of the transmission is dummy signal transmission, and event signals are repeatedly transmitted in the remaining time of 0.2 seconds.

  In addition, reception by the reception circuit 44 of the wireless communication unit 30 is an event signal from the other alarm devices 10-2 to 10-6 belonging to the same group as the alarm device 10-1, or an apparatus event signal from the emergency alarm device 25. Is received intermittently. In the intermittent reception, the reception operation is repeated for a predetermined period T3, for example, every T3 = 7 seconds, for a receivable time T4, for example, T4 = 100 milliseconds, and during the receivable time T4, the transmission dummy signal is carrier sensed. When the signal is detected, it switches to continuous reception for a predetermined time and receives an event signal or device event signal following the dummy signal.

  The received signal is decoded by the reception processing unit 62 provided in the processor 28. Hereinafter, the process up to this decoding may be referred to as reception. In particular, when the signal is determined to be valid as a result of decoding, it is called effective reception.

  In addition, the wireless communication unit 30 detects the fire or an event other than the fire and transmits an event signal, or receives the device event signal from the emergency warning device 25 and receives another housing police. Confirmation signal indicating that the event signal has been normally received from the other housing police devices 10-2 to 10-6, which belong to the same group as the housing police device 10-1 and have received it. It is monitored whether or not (hereinafter referred to as “ACK signal”) is effectively received.

  In the case where an ACK signal is not received among the other resident alarms, the resident alarm 10-1 transmits an event signal with a relay request to another resident alarm or the emergency alarm device 25 from which the ACK signal has been received or An event signal with a relay request is sent from the home alarm device or emergency warning device 25 that has transmitted the device event signal and received the event signal with the relay request or the device event signal to the home alarm device or emergency warning device 25 with no AKC signal response Relay device event signals. An AKC signal that has not received an AKC signal that has received a relay request event signal or device event signal relays back an ACK signal in response to a relay request event signal or device event signal. Is received by the home guard 10-1 of the interlocking source via the relay (reply relay). Accordingly, if there is a residence warning device or emergency warning device 25 that does not receive the ACK signal, it is determined as a communication failure or the like, and a predetermined failure handling process is performed.

  The memory 32 includes a serial number 48, which is a serial number indicating the order of event signals, a transmission source code 50 serving as resident alarm identification information for identifying each resident alarm, and a resident alarm installed in a house as shown in FIG. The group code | symbol 52 for comprising the interlocking | linkage group which performs a interlocking | linkage alarm in 10-1 to 10-6 is stored.

  FIG. 5 is an explanatory diagram schematically showing the event signal format used for the interlocking alarm in the present embodiment, and the device event signal is also the same. In FIG. 5, the event signal 46 includes a serial number 48, a transmission source code 50, a group code 52, and an event code 54.

  The serial number 48 is a serial number indicating the order of event signals, and is incremented by one each time an event signal is transmitted to each terminal (residential alarm device, emergency alarm device). The serial number 48 is generated asynchronously by each of the residential alarm 10 and the emergency warning device 25. The serial number 48 is used for managing event signal relay processing, etc., mainly in wireless communication between the residential alarm 10 and the emergency warning device 25, but since it is not directly related to the present invention, a detailed description will be given. Omitted.

  The transmission source code 50 is, for example, a 26-bit code used as the home alarm identification information, and uses, for example, the serial numbers of the home alarm 10 and the emergency warning device 25. The group code 52 is, for example, an 8-bit code. For example, the same group code is set for the residential alarm devices 10-1 to 10-6 and the emergency warning device 25 shown in FIG.

  As the group code 52, in addition to setting the same group code to the same group of house alarms, for example, a reference code common to the house alarms constituting a predetermined group and a transmission source unique to each house alarm A different group code may be used for each residential alarm obtained from the calculation with the code. In other words, any code can be used as long as each terminal (residential alarm device, emergency warning device) that has received the event signal can determine whether or not it is a signal from a terminal in the same group as itself. It may be.

The event code 54 is a code representing the event content such as a fire, gas leak (for example, a gas leak alarm device or a residence alarm device having a gas leak detection function), and in this embodiment, a 4-bit code is used. For example, 0001 = fire 0010 = gas leak 0011 = alarm stop (fire alarm stop, gas leak alarm stop, fault alarm stop)
0100 = recovery (fire recovery, gas leak recovery, failure recovery)
0101 = sensor failure 0110 = low battery failure 0111 = earthquake notification 1000 = tsunami notification.

  Note that the above-described code indicating “relay request is present” is omitted here, but it can be added to the event code by increasing the number of bits. In addition, both an identification code indicating a source (interlocking source) residence alarm and an identification code of a residence policer performing relay are added to the event signal or device event signal to be relayed. Further, an identification code for designating a transmission destination may be added.

  Further, although the above-described code indicating “relay request is present” is omitted here, for example, it can be added to the event code by assigning it to “1111”, for example. Further, for example, “0000” may be assigned for periodic communication confirmation. Of course, more event codes can be assigned by increasing the number of bits.

  Referring again to FIG. 1, the sensor unit 34 is provided with a smoke detector 16 that detects smoke and outputs a detection signal corresponding to the smoke density. As described above, instead of the smoke detector 16, the sensor unit 34 detects a temperature due to a fire and outputs a detection signal, and detects a change in other physical phenomenon caused by the fire and outputs a detection signal. Various elements and sensors may be provided.

  The notification unit 36 is provided with a speaker 56 that is an acoustic output device that outputs an alarm sound and the like, and an LED 22 that displays an alarm. The speaker 56 outputs various voice messages, alarm sounds, and the like held by itself from a voice synthesis circuit unit (not shown) via an amplification unit (not shown). The LED 22 displays an abnormality such as a fire by blinking, blinking, or lighting. Instead of the speaker 56, a buzzer or the like may be used. Further, instead of the LED 22, a two-color LED, a liquid crystal display, or the like may be provided. Of course, an LED and a liquid crystal display may be provided together.

  The operation unit 38 is provided with an alarm stop switch 20 and a mode switch 21. The alarm stop switch 20 functions as an alarm stop switch only when an alarm sound of a fire or failure is output from the notification unit 36 by the speaker 56 or when an alarm display is performed by the LED 22. For example, if the alarm stop switch 20 is operated during the alarm indicating the interlock source, the alarm sound and the alarm display are stopped, and if the alarm stop switch 20 is operated during the alarm indicating the interlock destination, the alarm sound and the alarm display are stopped. When the alarm stop switch 20 is operated during the alarm indicating the interlock destination, the alarm sound is stopped, and the alarm stop process is performed such that the alarm display stops or stops after a predetermined time from the alarm sound stop.

  On the other hand, the alarm stop switch 20 functions as an inspection switch in a normal state where a fire alarm or a failure alarm indicating the interlock source or the interlock destination is not performed, and operating the alarm stop switch 20 in this state causes a background as a built-in test. A predetermined self-inspection result stored in the memory 32 is referred to, and a voice message indicating the inspection result is output from the speaker 56 of the notification unit 36.

  Note that the self-inspection may not be performed in the background as a built-in test, but may be executed when the operation of the alarm stop switch 20 is detected in a normal state (when inspection is instructed). Further, when the alarm stop switch 20 is operated during the fault alarm, the fault alarm stop process may be performed after performing a predetermined self-inspection operation and informing the result. In this way, for example, the failure alarm stop process is performed after rechecking the sensor failure or the like, so that the user can be made to recognize the failure state more clearly. At this time, when the failure state has been resolved (failure recovery), for example, a message such as “the failure has been resolved” may be output, and the process may proceed to failure stop (recovery) processing.

  The mode switch 21 provided in the operation unit 38 is a dip switch or the like provided on the back surface of the main body, and can set the alarm prohibition mode of earthquake notification or tsunami notification to ON or OFF. When the prohibit mode is set (turned on) when the mode switch 21 is turned on, even if a device event signal indicating earthquake notification or tsunami notification is received from the emergency warning device 25, the earthquake notification output or tsunami notification output from the notification unit 36 is performed. I will not.

  Using this function, for example, when the house alarm 10 is also installed in the room where the emergency alarm device 25 is installed, or when the plurality of house alarms 10 are installed in the same room, etc. If necessary, information can be output only to a predetermined device in the room, so that it is possible to avoid redundant information output by multiple devices. An effect such as suppression can be obtained.

  The battery power source 40 uses, for example, a lithium battery or an alkaline battery having a predetermined number of cells, and has a battery capacity of, for example, 10 by reducing the power consumption of the entire circuit unit including the wireless communication unit 30 in the residential alarm 10-1. The battery life of the year is guaranteed.

  The processor 28 is provided with functions of an event detection unit 58, a transmission processing unit 60, a reception processing unit 62, an abnormality notification processing unit 64, an earthquake notification processing unit 65, and a failure processing unit 66 as functions realized by executing the program. The failure processing unit 66 is provided with functions of a sensor failure monitoring unit 68 and a low battery failure monitoring unit 70.

  The event detection unit 58 has the presence or absence of a fire detected from the smoke detection signal output of the sensor unit 34, the presence or absence of an alarm stop instruction input or inspection instruction input by the operation unit 38, the smoke detection signal output of the sensor unit 34 being reduced. Detects events such as fire restoration, sensor failure, low battery failure, etc., when the fire detection state is resolved. The event detection unit 58 is obtained as a result of decoding the event signals from the other home alarm devices 10-2 to 10-6 and the device event signal from the emergency alarm device 25 via the reception circuit 44 and the reception processing unit 62. The presence / absence of event signal valid reception and the event contents are detected.

  The transmission processing unit 60 detects the fire from the smoke detection signal output of the sensor unit 34 by the event detection unit 58, stops the alarm by the operation unit 38, and lowers the smoke detection signal output of the sensor unit 34, thereby eliminating the fire detection state. When a self-event such as a fire recovery is detected, an event signal indicating the detected event content is transmitted from the antenna 31 to the interlocked house alarm device or emergency alarm device via the transmission circuit 42 of the wireless communication unit 30. . In addition, the transmission processing unit 60 relays and transmits event signals that are effectively received from other residential alarm devices or the emergency warning device 25 as necessary.

  The reception processing unit 62 receives the event signal from the other residential alarm devices 10-2 to 10-6 and the device event signal from the emergency warning device 25 from the antenna 31 via the reception circuit 44 of the wireless communication unit 30. Decipher.

  The types of device event signals received from the emergency warning device 25 include device event signals indicating earthquake notification and tsunami notification, and operation of the alarm stop switch 108 provided in the emergency warning device 25 of FIG. There is a device event signal or the like indicating an alarm stop when stopping a fire alarm or the like.

  The abnormality notification processing unit 64 receives a signal from the event detection unit 58 when the event detection unit 58 detects a fire as its own abnormality, outputs an alarm sound indicating the interlocking source from the speaker 56, and drives the LED 22 to turn on, for example. Then, an alarm indicating the interlocking source is displayed, and an event signal indicating a fire is transmitted to the other residential alarm devices 10-2 to 10-6 and the emergency alarm device 25.

  Specifically, when the event detection unit 58 detects a fire based on the smoke detection signal of the smoke detection unit 16 provided in the sensor unit 34, the abnormality notification processing unit 64 indicates that fact from the event detection unit 58. Based on the received signal, the alarm unit 36 is controlled to repeatedly output an alarm sound indicating the link source from the speaker 56, for example, a voice message of “Woo Woo is a fire”, and the LED 22 is turned on to indicate the link source. The alarm display control is performed, and an event signal indicating a fire is further transmitted from the antenna 31 to the other residential alarm devices 10-2 to 10-6 and the emergency alarm device 25 via the transmission processing unit 64 and the transmission circuit 42. .

  In addition, the abnormality notification processing unit 64 detects when the event detection unit 58 detects that the fire event signal has been effectively received from any of the other mortgages 10-2 to 10-6 by the reception circuit 44 of the wireless communication unit 30. In addition, an alarm sound (notification sound) indicating the link destination is repeatedly output from the speaker 56 of the notification unit 36, for example, “Woo-woo, please confirm that another fire alarm has been activated”, and the LED 22 is blinked, for example. To display an alarm indicating the link destination.

  On the other hand, when an event signal indicating a fire from the home alarm device 10-1 is effectively received by the emergency warning device 25, the emergency warning device 25 reads from the speaker, for example, “Please confirm that the Woo Woo fire alarm has been activated”. The alarm sound by the voice message is repeatedly output and the alarm display for identifying the home alarm device that detects the fire is performed.

  The failure processing unit 66 is provided with functions of a low battery failure monitoring unit 68 and a sensor failure monitoring unit 70, and is automatically executed regularly in the background as a built-in test.

  The low battery failure monitoring unit 70 performs A / D conversion on the power supply voltage supplied from the battery power supply 40 directly or indirectly via a voltage detection circuit (not shown) at a predetermined measurement time interval, for example, T3 = 4 time intervals. Is read and compared with a predetermined threshold voltage. When the voltage is lower than this threshold voltage, a low battery failure detection is preliminarily determined, and when a low battery failure detection tentative determination continues for a predetermined number of times, a low battery failure is determined. (Confirm), set the low battery failure flag and store it in the memory 32.

  The sensor failure monitoring unit 68 reads the smoke detection signal output from the smoke detection unit 16 of the sensor unit 34 at a predetermined measurement time interval, for example, T1 = 1 second interval by A / D conversion, and holds it in the buffer area of the memory 32. For example, at every predetermined time interval T2 = 10 minutes, an average value of 10 minutes of detection data held in the buffer area of the memory 32 is obtained, and this average value is used as a predetermined reference level (referred to as a zero point level). When the output is lower, it is determined that the output is in a stopped state or the like, and a failure of the sensor unit 34 is determined. A sensor failure flag is set and stored in the memory 32.

  The reason why the 10-minute average value of the smoke concentration detection signal falls below the zero point is because of a failure such as failure of the light receiving element provided in the smoke detector 16, disconnection of the output signal line from the light receiving element, or stop of the light receiving amplifier. Because it is highly likely that this is due to the fact that it has

  Even when a temperature detection element such as a thermistor is provided in the sensor unit 16, a sensor failure can be similarly detected by various processes. In addition, disconnection of the output line to the speaker 56, other circuit failures, communication abnormalities, and the like can be similarly monitored. Such a failure is also collectively referred to as a sensor failure in the present embodiment because processing similar to that for a sensor failure is performed after detection.

  When the event detection unit 58 detects a sensor failure or a low battery failure determination, the abnormality notification processing unit 64 indicates a sensor failure alarm indicating an interlocking source by an alarm sound from the speaker 56 of the notification unit 36 and the display of the LED 22. Or, a low battery failure alarm is output.

  In addition, when the event detection unit 58 detects a sensor failure determination or a low battery failure determination, the abnormality notification processing unit 64 indicates an interlocking source by an alarm sound and / or display of the LED 22 from the speaker 56 of the notification unit 36. While outputting the sensor failure alarm or the low battery failure alarm, the abnormality alarm processing unit 64 sends the sensor failure event signal or the low battery failure event signal from the transmission circuit 42 of the wired communication unit 30 to the other housing alarm device 10 via the antenna 31. -2 to 10-6 and the emergency alarm device 25, and the sensor alarm or the low battery fault alarm indicating the link destination is sent to the house alarm devices 10-2 to 10-6 and the emergency alarm device 25 as an alarm sound and / or Let the display do.

  Furthermore, the abnormality notification processing unit 64 has effectively received a sensor failure event signal or a low battery failure event signal from any of the other residential alarm devices 10-2 to 10-6 via the reception circuit 44 and the reception processing unit 62. When this is detected by the event detection unit 58, a sensor failure alarm or a low battery failure alarm indicating the linkage destination is output by an alarm sound from the speaker 56 of the notification unit 36 and the display of the LED 22.

  In addition, when the event detection unit 58 detects the sensor failure determination, the abnormality notification processing unit 64 outputs, for example, “pick failure” from the speaker 56 of the notification unit 36 as a sensor failure alarm sound indicating the link source (failure source). For example, the LED 22 is turned on continuously for a plurality of times and the LED 22 is turned on, and thereafter, a process of outputting a sound “pick failure” and displaying the LED 22 a plurality of times is repeated at regular intervals.

  In addition, when the event detection unit 58 detects the sensor failure determination, the abnormality notification processing unit 64 transmits the sensor failure event signal to the other residential alarm devices 10-2 to 10-6 via the transmission processing unit 60 and the transmission circuit 42. By transmitting to the emergency alarm device 25, a sensor failure alarm indicating the link destination is output. At this time, for example, “beep alarm device is faulty” or “beep alarm device is faulty” is output as an alarm sound, and a flashing display different from that of the interlock source is performed.

  In addition, when the event detection unit 58 detects the determination of the low battery failure, the abnormality notification processing unit 64 uses, for example, a “low battery failure alarm sound” as a low battery failure alarm sound indicating the link source (failure source) from the speaker 56 of the notification unit 36. "" Is continuously output a plurality of times, and the LED 22 is turned on, for example, and thereafter, the process of outputting a sound “battery exhausted” and displaying the LED 22 a plurality of times is repeated at regular intervals.

  When the event detection unit 58 detects the low battery failure determination, the alarm processing unit 64 transmits a low battery failure event signal to the other residential alarm devices 10-2 to 10-6 and the emergency warning device 25. , The low battery failure alarm indicating the linkage destination is output as an alarm sound, “Peep alarm is out of battery” or “Pi alarm is out of battery” and a blinking display different from the linkage source is performed.

  Further, the abnormality notification processing unit 64 detects the operation of the alarm stop switch 20 during the output of the fire alarm sound indicating the interlocking source or the fire alarm sound indicating the interlocking destination, or other residential alarm devices 10-2 to 10-6. When the event signal indicating the alarm stop from the emergency alarm device 25 or the reception of the device event signal is detected, the output of the fire alarm by the voice message from the speaker 56 and the alarm display of the LED 22 is stopped. At this time, the alarm display by the LED 22 may be stopped after continuing for a predetermined time. In addition, during the fire alarm indicating the interlock source, at least the output of the alarm sound may be continued even if an event signal indicating the alarm stop or the device event signal is received.

  Further, when the abnormality notification processing unit 64 detects an alarm stop operation of the alarm stop switch 20 provided in the operation unit 38 during the output of the sensor failure indicating the interlocking source or the low battery failure alarm, the alarm sound indicating the own interlocking source is generated. Is stopped after the failure display is continued for a predetermined time, and an alarm stop event signal is transmitted to the other alarm devices 10-2 to 10-6 and the emergency alarm device 25 that are outputting the failure alarm indicating the interlocking destination. Then, the failure alarm sound and the failure display of the residence warning devices 10-2 to 10-6 and the emergency warning device 25 are stopped.

  When the event detection unit 58 detects effective reception of the device event signal indicating the earthquake notification from the emergency warning device 25 via the reception circuit 44 and the reception processing unit 62, the earthquake notification processing unit 65 is used as information indicating the earthquake notification. For example, a voice message such as “Peep Earthquake Early Warning. Be wary of strong shaking” is output from the speaker 56 of the notification unit 36 for a predetermined time or a predetermined number of times (including once), and the LED 22 is lit, blinks, or blinks.

  The earthquake notification processing unit 65 also notifies the tsunami notification when the device event detection unit 58 detects that the device event signal indicating the tsunami notification is received from the emergency warning device 25 via the reception circuit 44 and the reception processing unit 62. For example, a voice message such as “Peepee Tsunami Warning has been issued. Please do not approach the beach and evacuate to the hill” is output from the speaker 56 of the notification unit 36 for a predetermined time or a predetermined number of times (including once). LED 22 is turned on, blinks, or blinks.

  When the event detection unit 58 detects the setting of the prohibit mode in which the output of the information indicating the earthquake notification and the tsunami notification is prohibited by the setting ON operation of the mode switch 21, the emergency notification device 25 Even if a device event signal indicating earthquake notification or tsunami notification is received from the above, the voice message output and display of information indicating earthquake notification or tsunami notification is not performed.

  In addition, when a mode switch for setting the prohibit mode is provided in the operation unit of the emergency alarm device 25 described later, the fire alarm output from the emergency alarm device 25 may be prohibited by setting the mode switch.

  Even when voice messages and sound output are prohibited, only display may be performed, and conversely, only display may be prohibited. Further, this may be specified separately. That is, the output prohibition setting can be appropriately selected and set for the earthquake notification and the earthquake notification test, and the sound output and the display output.

  In this way, the notification method can be selectively set according to the type of event for which notification output is performed, and an appropriate notification pattern can be obtained depending on the user's wishes and the installation status of the device. Easy to use.

  8 to 10 are flowcharts showing an example of the monitoring process in the residential alarm 10-1 of FIG. It becomes the same process also about the other residence alarm devices 10-2 to 10-6. In FIG. 8, when the power supply by the battery power source 40 of the home guard 10-1 is started, various settings including initialization, self-diagnosis, and prohibition mode setting are read in step S1, and an abnormality is detected. If not, the process proceeds to step S2 to monitor the fire. If there is an initialization abnormality in step S1, the notification unit 36 notifies that fact and stops the operation halfway or performs the processing of step S1 again, but the illustration is omitted.

  When the smoke detection signal output from the sensor unit 34 exceeds a predetermined fire level, a fire is detected. In step S2, a fire detection is detected and the process proceeds to step S3. After wirelessly transmitting an event signal including a transmission source code, a group code to be identified, and an event code indicating a fire to other residential alarm devices and the emergency warning device 25, a voice message or a buzzer sound is transmitted from the speaker 56 of the notification unit 36 in step S4. A fire alarm indicating an interlocking source is output by an alarm sound due to, for example, an alarm display by turning on the LED 22, for example.

  Subsequently, in step S5, the presence or absence of a fire recovery in which the smoke detection signal from the sensor unit 34 is reduced to cancel the fire detection state is detected. When a fire recovery is detected, a serial number, a transmission source code, and a group are detected in step S6. After transmitting the event signal including the code and the event code indicating the fire recovery to the other housing alarm device and the emergency alarm device 25, in step S7, the alarm source from the speaker 56 and the alarm display by lighting the LED 22 are indicated. Stop the fire alarm. The alarm display by the LED 22 may be turned off after a predetermined time has elapsed.

  Subsequently, whether or not the alarm stop switch 20 is operated is detected in step S8, and when the switch operation is detected, the presence or absence of an alarm is detected in step S9. When the alarm is detected in step S9, the process proceeds to step S10, and an event signal including a serial number, a transmission source code, a group code, and an event code indicating an alarm stop is transmitted to the other residential alarm and the emergency alarm device 25, Proceeding to S11, the alarm sound output indicating the interlocking source from the speaker 56 is stopped, and the alarm display by turning on the LED 22 is turned off. The LED 22 may be turned off after a predetermined time has elapsed.

  When it is detected in step S9 that an alarm is not being issued, the operation of the alarm stop switch detected in step S8 is recognized as an inspection instruction operation, and a predetermined inspection operation is performed to notify the result. Is omitted.

  Subsequently, the process proceeds to step S12 in FIG. 9 to detect the presence / absence of effective reception of an event signal indicating a fire from another house alarm. When it is detected that an event signal indicating a fire from another house alarm is effectively received, the process proceeds to step S13, where an alarm sound is output from the speaker 56 as a fire alarm indicating the interlocking destination, and an alarm display by blinking of the LED 22 is performed.

  Next, in step S14, the presence / absence of an effective reception of an event signal indicating fire recovery from another house alarm is detected, and if the presence of an effective reception of an event signal indicating fire recovery is detected, the process proceeds to step S15 and the linked destination is detected. The alarm display by the alarm sound output from the speaker 56 and the blinking of the LED 22 is stopped as an alarm.

  Next, in step S16, it is checked whether or not there is an effective reception of an event signal indicating an alarm stop from another house alarm or a device event signal indicating an alarm stop from the emergency alarm device 25, and an event signal indicating an alarm stop or When it is detected that the device event signal is validly received, the process proceeds to step S17 to detect the presence or absence of an alarm. When the alarm is detected, the process proceeds to step S18 and the alarm sound output as the interlocking destination is stopped and the alarm display is also stopped. .

  Subsequently, in step S19, the presence / absence of the prohibition mode setting of the earthquake notification is detected. If the prohibition mode is not set, the process proceeds to step S20 to detect the presence / absence of effective reception of the event signal indicating the earthquake notification. When the presence of effective reception of the device event signal indicating the earthquake notification is detected in step S21, an audio message such as “Peep emergency earthquake warning, please watch out for strong shaking” is sent from the speaker 56 of the notification unit 36 to 1 or For example, the LED 22 is turned on while outputting a plurality of times.

  Subsequently, in step S22, the presence / absence of effective reception of an event signal indicating tsunami notification is detected, and when the presence of effective reception of a device event signal indicating tsunami notification from the emergency warning device 25 is detected, tsunami notification is indicated in step S23. A voice message such as “Peepee Tsunami Warning has been issued. Please do not approach the coast and evacuate to the hill” is output from the speaker 56 of the notification unit 36 one or more times, and the LED 22 is turned on, for example.

  If an earthquake notification prohibit mode setting is detected in step S19, steps S20 to S23 are skipped, and a voice message indicating earthquake notification or tsunami notification is output even if reception of a device event signal indicating earthquake notification or tsunami notification is detected. do not do. This is a case where the residential alarm 10-1 is installed in the same room as the emergency alarm device 25 as shown in FIG. Step S19 and step S20 may be switched in order.

  Subsequently, the process proceeds to step S22 in FIG. 10 to detect the presence or absence of a low battery failure. When it is detected that there is a low battery failure, the process proceeds to step S23 where the low battery failure flag is set and stored in the memory 32 and the periodic notification timer is started. To do.

  Subsequently, in step S24, a low battery failure warning output indicating a failure source and an alarm display are performed, and then in step S25, a low battery failure event signal is transmitted to the other residential alarm device and the emergency warning device 25.

  In step S26, the presence or absence of a sensor failure is detected. If a sensor failure is detected, the flow advances to step S27 to set and store a sensor failure flag in the memory 32 and start a periodic notification timer.

  Subsequently, in step S28, a sensor failure alarm output and an alarm display indicating the source of the failure are performed. Then, in step S29, a sensor failure event signal is transmitted to the other residential alarm device and the emergency warning device 25.

  Subsequently, in step S30, it is detected whether or not a failure flag indicating a low battery failure or a sensor failure is set in the memory 32. When the failure flag is set, the process proceeds to step S31, and the periodic ringing timer started in step S23 or S27. If the periodic ringing timing is detected, the process proceeds to step S32. If the low battery failure flag is set at that time, a low battery failure alarm is output, and if the sensor failure flag is set. , Output sensor failure alarm.

  Subsequently, the presence / absence of operation of the alarm stop switch 20 is detected in step S33, and if the operation is detected, the process proceeds to step S34, and it is detected whether or not the failure flag set by executing the inspection process is stored in the memory 32. If it is detected that the failure flag is not stored, the process proceeds to step S35, and, for example, fire alarm sound and alarm display test notification are performed as normal notification. In this test notification, the fire alarm sound is output only once with the sound volume turned down to notify the user that the home alarm device 10 operates normally.

  If it is detected that the failure flag is stored in step S34, the process proceeds to step S36. If it is detected that the low battery failure flag is stored, a low battery failure alarm is output and the sensor failure flag is stored. If so, a sensor failure alarm is output. For this reason, after a failure alarm is issued due to detection of a low battery failure or a sensor failure, an inspection instruction is input by detecting operation of the alarm stop switch 20 in a normal state in addition to outputting a failure alarm every predetermined time by a periodic ringing timer. A fault alarm is also output when an error is detected. The above processing is repeated until an operation stop instruction due to power-off is detected.

  In the flowcharts of FIG. 8 to FIG. 10, processing when an event signal indicating a low battery failure or a sensor failure is received from another residential alarm is omitted, but a low battery failure or a When valid reception of an event signal indicating a sensor failure is detected, a low battery failure alarm or a sensor failure alarm indicating a link destination is performed with an alarm sound and an alarm display.

  11 and 12 are flowcharts showing a processing example of the emergency warning device 25 shown in FIG. In FIG. 11, when the emergency warning device 25 is turned on, initialization and self-diagnosis are performed in step S40. If there is no error, the process proceeds to step S41, and FM station tuning processing is performed by the tuning operation of the operation unit 80.

  Subsequently, the process proceeds to a reception standby operation in step S42. In the reception standby operation, the FM receiving unit 74 is operated to receive and reproduce FM broadcast radio waves, but the operation of the audio amplifying unit 76 is stopped and no broadcast is transmitted from the speaker 78.

  Subsequently, in step S43, the presence / absence of the chime sound of the earthquake early warning is detected through the analysis process of the analysis unit 94. When the chime sound reception is detected, the process proceeds to step S44, and the sound amplifying unit 76 is operated to receive it. The broadcast of the earthquake early warning that is being performed is output from the speaker 78 at a predetermined set volume.

  Next, in step S45, a device event signal indicating an earthquake notification is transmitted to the home alarm device 10 via the transmission control unit 100, the transmission circuit 90 of the wireless communication unit 84, and the antenna 85. Subsequently, in step 46, the elapse of a predetermined time is waited for, and the process proceeds to step S47, where the operation of the audio amplifying unit 76 is stopped to stop the output of the broadcast sound.

  Subsequently, in step S48, the presence / absence of reception of the tsunami warning signal is detected through the analysis process of the analysis unit 94. When the effective reception of the tsunami warning signal is detected, the process proceeds to step S49, and the voice amplification unit 76 is operated. The tsunami warning by the emergency warning broadcast that is being received is output from the speaker 78 at the set volume.

  Next, in step S50, a device event signal indicating a tsunami notification is transmitted to the home guard 10 via the transmission control unit 100, the transmission circuit 90 of the wireless communication unit 84, and the antenna 85. Subsequently, when the effective reception of the end signal in the emergency warning broadcast is detected through the analysis process of the analysis unit 94 in step 52, the process proceeds to step S43, and the operation of the audio amplification unit 76 is stopped to stop the output of the broadcast sound.

  Subsequently, the process proceeds to step S53 in FIG. 12, and the presence / absence of effective reception of an event signal indicating a fire from any of the residential alarms 10 is detected. When an event signal effective reception indicating a fire from any of the residence guards 10 is detected in step S53, the process proceeds to step S54, and the transmission source code management table 110 is searched using the transmission source code included in the event signal that has been effectively received. A house police number indicating a fire alarm and a room name indicating an installation location are acquired. In step S55, a room number or an installation location room indicating a fire alarm is detected. A fire alarm sound by a voice message including a name is output from the speaker 78, and the house alarm number and the room name of the installation location are displayed by the house alarm display 81.

  Next, in step S56, together with the presence or absence of an alarm stop instruction by the operation of the alarm stop switch 108 provided in the operation unit 82, an event signal indicating a fire recovery from any of the residential alarms 10 or an event signal effective reception indicating an alarm stop is received. If an alarm stop instruction by operation or an event signal reception indicating a fire recovery is detected or an event signal valid reception indicating an alarm stop is detected, the process proceeds to step S57 to detect the presence or absence of an alarm. When the inside is detected, the process proceeds to step S58 to stop the fire alarm sound and the alarm display.

  Here, when the alarm is stopped based on the detection of the operation instruction input of the alarm stop switch 108 provided in the operation unit 82, the alarm is sent from the transmission circuit 90 of the wireless communication unit 84 to the home alarm device 10 via the antenna 85. A device event signal indicating a stop is transmitted.

  In addition, regarding the stop of the fire alarm display in step S58, when it is detected that the event signal indicating the fire recovery from any of the residential alarms 10 or the event signal indicating the alarm stop is present, the event signal that is effectively received is displayed. The transmission source code management table 110 is searched with the included transmission source code, and the house guard number and room name of the house guard that has recovered from the fire or the alarm is stopped are acquired, and the corresponding display on the house guard display unit 78 is stopped. .

  Then, it progresses to step S59 and the presence or absence of the effective reception of the event signal which shows the low battery failure from either of the resident guards 10 is detected.
