Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monitoring device for detecting an abnormal state such as an intruder or a fire in a security system for general households or business establishments, and notifying a monitoring destination such as a monitoring center. Relates to a monitoring device having a function of reducing power consumption so that when a power failure occurs, important objects and disasters can be monitored by a backup power supply for a long time.

[0002]

2. Description of the Related Art As a crime prevention / disaster prevention system (monitoring system) for general households and business establishments, it detects abnormalities and notifies them with an emergency bell, etc., and depending on the detected state, uses a telephone line to a security company. Contact is made and measures are taken to prevent abnormalities. That is, various sensors are installed to detect an abnormal condition such as a person intruding into the building to be monitored or a fire, and when the abnormal condition is detected by the sensor, the monitoring device presets 2. Description of the Related Art A monitoring system is known that reports an abnormal condition to a report destination such as a center. Various sensors in such a monitoring system are indispensable elements for accurately detecting an abnormal state in the system.

Now, as described above, a plurality of sensors of different types are connected to the monitoring device in order to detect various objects and states. Normally, such a monitoring device receives power supply from an external power supply to start up its own device, and also supplies power to the connected sensor. In such a monitoring system, the various sensors and the monitoring device are usually connected by a signal line for transmitting a detection signal from the sensor and a power line for supplying power to the sensor. In some cases, the signal line and the power line are also used.

Further, as a method for the monitoring device to identify the sensor, the identification is made based on which connection terminal of the monitoring device is connected to the sensor, or the sensor is assigned an address and sent from the sensor. There are cases where identification is performed based on the address information to be used. In addition, these may be used together. The monitoring device of the above monitoring system is provided with a backup power supply by a battery, and even if the supply from the external power supply is cut off for some reason, switching to backup will continue monitoring. You can do it.

When performing such backup, it has been proposed to intermittently operate the fire detection sensor in order to reduce power consumption. In the case of fire detection, flames and smoke are continuously generated, so even if the sensor is operated intermittently, the possibility of overlooking the flames and smoke is low, and it is effective if the operation cycle is set appropriately (power supply). That's the method.

[0006]

However, in the conventional monitoring device as described above, the backup by the battery recovers from the power failure in a relatively short time because most of the power failure is restored in a short time. However, there is a risk that the battery cannot be backed up or the monitoring device stops functioning due to the limited capacity of the battery when the power failure is long.

In the case of a previously known regional power outage or a power outage due to inspection of power supply facilities in a tenant building, etc., a dealer or a section in charge will inform the customer, and an additional battery should be connected in advance. However, if a sudden power outage occurs for a long period of time, and if the power outage lasts for a long period of time, the site will be backed up while the battery is backing up. It was necessary to go to the other side and connect an additional battery, and the like, and it became a heavy work load.

In order to deal with such a problem, it is conceivable to change to a large battery, to increase the battery, or to change to a small battery having a large capacity so that backup can be performed for a long time. However, none of them could be easily reflected due to the size of the device, the installation space, and the cost.

Further, in a system in which the sensor is periodically turned on / off to achieve low power consumption, when an intruder detects an intrusion, the intruder crosses in front of the sensor and is detected by the sensor. Because the timing to
If the intruder detection sensor is operated intermittently, there is a high possibility that an intruder will be overlooked.

Further, since an infrared sensor generally used as an intruder detection sensor has a long rise time of about 30 seconds from power-on to stable operation, it is not intermittently operated. In addition to being efficient, stable detection will not be performed in the initial stage.

As described above, in the conventional monitoring device, when the supply from the external power source is cut off and the battery is used for backup, the time until the power failure is restored or the time when the guard arrives at the site (monitoring in the power failure area) There is a problem specific to the security system in that the power supply to the sensor must be as long as possible in order to recover the safety of the surveillance area and to recover the system (it takes time when there are many systems).

The present invention has been made in view of the above, and reduces the power consumption when the supply from the external power source is cut off, so that the maximum capacity can be achieved without changing the capacity of the existing battery. The purpose is to realize the backup time of and to avoid the blank of the monitoring of the specific monitoring target.

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of a monitoring apparatus according to the present invention will be described in detail below with reference to the accompanying drawings. The present invention is not limited to the contents described in this embodiment.

According to the present invention, when the external power supply supplied to the monitoring device is in a power failure state due to electrical work, inspection, or interruption by an intruder, security among the plurality of sensors connected to the monitoring device is provided. By supplying power from the backup power supply to the sensor with high priority according to the status and cutting off the power supply to other sensors with low priority, it shifts to the low power consumption mode and backs up for a long time. It will be realized. The details will be described below.

(Embodiment 1) FIG. 1 is a block diagram showing a first configuration of a monitoring apparatus according to an embodiment of the present invention. The monitoring device 100a performs a control unit 101 that totally controls the device according to a control program, a power supply unit 102 described later, a connection terminal unit 103 to which a sensor is connected, and a notification process when an abnormal situation occurs. A reporting unit 104 to perform, and a timer 105 for measuring elapsed time of power failure
And are equipped with.

The power supply unit 102 has a power supply unit 106 serving as a main power supply, a rechargeable battery 107, and a power failure detection unit 108 for detecting interruption of power supply from the outside.
And a capacity detection unit 109 that detects the capacity of the battery 107.
And are equipped with. Reference numeral 110 is an external power source. The notification unit 104 is connected to the monitoring center 112 via the telephone line 111.

The connection terminal portion 103 includes, for example, switching portions 103a, 103b, 103c formed of switches.
Is provided, and these switching units 103a, 103b, 10
3c is a sensor / sensor group 114a, 1 divided into power supply / interruption priorities at the time of power failure as described later.
14b and 114c are connected. These sensors /
The sensor groups 114a, 114b, 114c are the monitoring device 10.
It operates by receiving power supply from 0a.

The following are examples of sensors.
For the intrusion of a suspicious person, for example, a piezoelectric element or a strain gauge that detects a pressure change due to an impact force when a window glass or a door is broken is used. Further, a magnet sensor, an infrared sensor, or the like is used for opening and closing windows and doors. Further, if such an intruder detection sensor detects an intruder while guarding, the flash is further turned on and the CCD is turned on.
An image is taken by a camera.

For a fire or the like, a heat detecting sensor such as a bimetal type for heat generation, a reducing gas for a smoke is detected by a semiconductor sensor such as SnO _2, or a smoke sensor using americium as a radiation source. Is used. Gas leaks are detected by a gas sensor. For water leakage, a water leakage sensor or an earth leakage breaker that uses a short circuit between electrodes is used.

The control unit 101 is composed of, for example, a microcomputer system, and its input port is switched between a guarded state (guarded and unguarded) by operation by a resident of a general household to be guarded or an employee of a business office. A security switching unit 120 for performing is connected. Note that the connecting portion 113a
Although ~ 113c are shown as three here, these numbers are for convenience of description, and there are actually more numbers. That is, an arbitrary number and type of objects are installed according to the security target.

The monitoring device 100a configured as described above
In the above, the power failure detection unit 108 detects a power failure state depending on whether or not power is being supplied from the external power supply 110, and when power failure is detected, the power supply is switched to the battery 107. Also, if you recover from a power outage,
The power supply is switched to the external power supply 110. In this way, the monitoring device 100a requires power to drive these sensors in addition to power to drive the device itself. Therefore, power consumption increases according to the number of connected sensors.

The timer 105 measures a predetermined time after a power failure is detected by the power failure detecting section 108. Notification unit 104
Notifies an addressee such as the monitoring center 112 via a communication line 111 such as a telephone line when an abnormal situation is detected. The control unit 101 controls each of the above-described element blocks, and in particular, after a power failure is detected, stops the power supply to other than the sensor that monitors the important object. Examples of important items include a sensor that detects an intruder near a valuable such as a safe and a sensor that detects a fire.

When a power failure occurs for some reason, the monitoring apparatus 100a measures the elapsed time with the timer 105, and when the predetermined time has elapsed, stops the power supply to the predetermined sensor, or When the capacity detection unit 108 detects that the remaining amount of the battery 107 has become less than or equal to a predetermined value, the power supply to the less important sensor is stopped. This power supply control at the time of power failure may be selected, or both may be combined. Sensor / sensor group 114a, 1
Switching portions 113a, 113b, 113c such as switches are provided in the connection terminal portion 103 with 14b, 114c, respectively, and power supply / stop is switched for each input terminal to reduce power consumption.

Next, a series of operations at the time of power failure in the monitoring device configured as described above will be described with reference to a flowchart. Note that this operation is performed by the power supply control as will be described later, depending on whether the security is being released or the security is set, which is set by the operation of the security switching unit 120 by a resident of a general household to be protected or an employee of a business establishment. The target sensor in is different.

FIG. 2 is a flowchart showing a first operation example of the monitoring device according to the first embodiment of the present invention. Normally, the external power supply 11 is connected to all the sensors (sensors / sensor groups 114a, 114b, 114c) connected to the apparatus.
Monitoring operation is performed by supplying power from 0 (step S
11) Always judge whether there is a power outage (step S
12). That is, the state of power supply from the external power supply 110 is checked in the normal monitoring state of all the sensors.

When it is determined in step S12 that a power failure has occurred for some reason, the battery 107 is switched to backup power supply (step S1).
3). Further, the switching units 113a to 11 of the connection terminal unit 103
3c connected to each of the sensors / sensor groups 114a-
Of 114c, the power supply to the lower priority sensor is shut off according to a predetermined priority (step S14), and the selective monitoring operation is performed (step S15). Then, it is judged whether or not the power failure state is restored (step S16), and when the power failure is restored, the procedure returns to step S11, and the normal monitoring operation is performed. Hereinafter, such an operation is repeated by checking the power failure state by the power failure detecting unit 108 and according to the check result.

Here, the determination of the priority of the above-mentioned sensor (determination criterion) will be described. When performing the monitoring operation, the positioning of the importance of each sensor differs depending on whether the security is being released or the security is being performed. Switching between the release of the security and the security is performed through the security switching unit 120 by an operation by a resident of a general household to be protected or an employee of a business establishment.

In addition to detecting the intrusion of a suspicious person, the monitoring system also detects disasters such as fires and equipment system abnormalities. When the security is being released, it is not necessary to detect an intruder with a sensor because someone is inside the building. In this case, power must be supplied to the fire detection sensors (including smoke detectors and gas leak detectors) because it is necessary to notify people in the building by detecting a fire or other disaster and notify the outside of the fire. And enable (power supply). In addition, if there is a possibility that serious damage will occur immediately when an abnormality occurs in the equipment system monitoring (tank water reduction, leak detection, etc.), power is supplied to the sensor to enable it (power supply). In addition, the emergency button to notify the occurrence of an emergency is also valid (power supply).

On the other hand, in the case of security, it is necessary to detect an intruder in addition to the case of the security release. As mentioned above, there are various types of intruder detection sensors.A magnet switch installed on a door or window to detect opening / closing of the door or window and a magnetic switch using a reed switch, or a glass installed on a window to break glass ( There is a glass breakage sensor (piezoelectric element, strain gauge, etc.) that detects the action), an infrared detection sensor that is installed in a passage or a room to detect an intruder.

These intruder detection sensors are divided into those that detect an intrusion into a building at an early stage and those that detect an approach to an important object such as a safe or a confidential document, and the purpose is to detect an intruder to the important object. The sensor installed in 1 is given priority (effective for power supply).

If there is a safe in the building, the infrared sensor installed in the room where the safe is placed, or the magnet switch installed in the door of the room where the safe is placed, is given priority (power supply). ).

The number of sensors to be activated (power supply) may be one or plural. Further, regarding which sensor is valid, how many sensors are valid, etc., the backupable time of the battery 107 and the priority of power supply to the sensor at the time of power failure are determined according to each security status. I'll do it. That is, these priorities are determined in advance, and these are set to the connection units 113a to 113c.
Set for each.

FIG. 3 is a flowchart showing a second operation example of the monitoring device according to the first embodiment of the present invention. First, similar to FIG. 2, the connection portions 113a to 113c of the present device.
Normal monitoring operation is performed by supplying power from the external power supply 110 to all the sensors connected to (step S2
1) Always judge whether there is a power failure (step S2)
2). That is, in the normal monitoring state of all the sensors, the state of the power supply from the external power source 110 is determined by the power failure detection unit 1
Check with 08.

When it is determined in step S22 that a power failure has occurred for some reason, the battery 107 is switched to backup power supply (step S2).
3). Furthermore, the timer 105 measures the power failure time,
It is determined whether or not a predetermined time has passed (step S2).
4). Here, if a power failure state occurs even after a predetermined time has elapsed, the sensors / sensor groups 114a to 114c connected to the switching units 113a to 113c of the connection terminal unit 103, respectively.
Among these, according to a predetermined priority, the power supply to the lower priority sensor is cut off (step S
25) and shifts to the selective monitoring operation (step S2)
6). On the other hand, normal monitoring operation is performed until a predetermined time has elapsed.

Thereafter, it is judged whether or not the power failure state has been restored (step S27), and if it is restored, step S2
Returning to 1, the normal monitoring operation is performed. Hereinafter, such an operation is performed by detecting the power failure state with the power failure detection unit 108, checking the power failure time with the timer 105, and repeatedly according to the check result.

In this way, when the power supply to the sensor is cut off after the lapse of a predetermined time from the occurrence of the power failure, the normal monitoring operation is continued in the short power failure until the lapse of the predetermined time. On the other hand, in the case of a long power failure in which a predetermined time elapses, the power supply to a predetermined sensor is cut off to reduce the power consumption of the battery 107 and realize the long-term monitoring of important objects.

FIG. 4 is a flowchart showing a third operation example of the monitoring apparatus according to the first embodiment of the present invention. First, similar to FIG. 2, the connection portions 113a to 113c of the present device.
A normal monitoring operation is performed by supplying power from the external power supply 110 to all the sensors connected to (step S3
1) Always judge whether or not there is a power failure (step S3)
2). That is, in the normal monitoring state of all the sensors, the state of the power supply from the external power source 110 is determined by the power failure detection unit 1
Check with 08.

When it is determined in step S32 that a power failure has occurred for some reason, the battery 107 is switched to backup power supply (step S3).
3). Further, the battery 107 is detected by the capacity detection unit 109.
The remaining amount of is detected and it is determined whether the capacity is less than or equal to a predetermined value (step S34). Here, if the capacity of the battery 107 is less than or equal to a predetermined value, the second low power consumption mode determined in advance is entered (step S35), and if the battery capacity is sufficient, the first low power consumption mode is entered. (Step S36) Or, the normal monitoring mode is performed. Note that the first low power consumption mode consumes more power than the second low power consumption mode, and may be selected stepwise. In some cases, the first low power consumption mode is normally set. The monitoring mode may be set to. That is,
The first low power consumption mode is located between the second low power consumption mode and the normal monitoring operation, and if it is almost the same as the normal monitoring operation, the first power consumption mode is set as the normal monitoring operation. Good.

That is, in the second low power consumption mode of step S35, the switching portions 113a to 113a of the connection terminal portion 103 ...
Sensor / sensor group 114 connected to each 113c
Among a to 114c, the power supply to the sensor with the lower priority is shut off according to a predetermined priority, and the selective monitoring operation is performed.

Thereafter, it is judged whether or not the power failure state is restored (step S37), and if restored, step S3.
Returning to 1, the normal monitoring operation is performed. On the other hand, step S
If the power failure is not restored in 37, the process returns to step S34 and the subsequent operations are executed. Hereinafter, such an operation is performed by detecting the power failure state by the power failure detecting unit 108, further detecting the capacity of the battery 107 which is the backup power source by the capacity detecting unit 109, and repeatedly executing it according to the detection result.

Therefore, when the capacity of the battery 107 used as the backup power source is detected by the capacity detecting unit 109 and the power supply to the predetermined sensor is cut off when the remaining amount becomes less than the predetermined value, the capacity of the battery 107 has a margin. If there is a certain state, a normal monitoring is realized in the monitoring system of relatively low power consumption, or by shifting to the first low power consumption mode which is relatively close to the normal monitoring operation, it is close to normal. You can monitor. Further, when the power consumption is large or when the battery 107 is not sufficiently charged, the power consumption is suppressed early by switching to a second predetermined low power consumption mode, and important objects can be monitored. It becomes possible to do it in a long time.

(Second Embodiment) FIG. 5 is a block diagram showing the structure of a monitoring apparatus according to the second embodiment of the present invention. The monitoring device 100b is different from the above-described configuration of FIG. 1 in that the switching unit (switch) of FIG. 1 is omitted, and instead, a control signal output unit 150 that outputs an energization control command for the sensor to the connection terminal unit 160 by an address. Is provided
Sensors 161a to 1 each having an address set
61c is connected to the connection terminal portion 160. Further, each of these sensors 161a to 161c includes a sensor portion 162 that performs its own detection, a power control portion 163 that performs ON / OFF control (power saving) of its own sensor, and a status display portion 170 that notifies the operating status of the sensor by LED lighting. Have
Since the other components and their functions are the same as those in the first embodiment, the same reference numerals as those in FIG.

The monitoring device 100b configured as described above
At, in response to a command from the control unit 101, the control signal output unit 150 outputs a start / standby signal to the power control unit 163 of any sensor. At this time, the sensor is designated by the address previously assigned to each sensor.

The power control unit 163 determines whether the standby signal is for its own sensor according to the address set for its own sensor, and if the standby signal for its own sensor is received, it goes to the sensor section 162. The power supply of the sensor part 162 is cut off or the sensor part 162 is switched to the standby state to suppress the power consumption in the sensor part 162. When the activation signal is received, the sensor portion 16
The power supply to 2 is restarted, or the sensor is switched from the standby state to the operating state, and the normal detection operation is performed. As described above, in the second embodiment, the power consumption is reduced by switching the operation and the stop for each sensor.

Further, the monitoring device 100 according to the second embodiment
In b, it is possible to switch the sensor to the standby state stepwise. The sensor used in this case can supply power separately to the detection part that detects a fire or an intruder, and the part other than the detection part that displays the operating state of the sensor, or operates separately. / It is configured to be switched to the standby state.

The status display section 170 of each sensor informs its operating status by lighting an LED or the like, but it is not always a necessary function except when the sensor is inspected. Therefore, as the first step, these parts are switched to the standby state, and then the entire sensor is switched to the standby state. Therefore, in the first stage,
The detection function of the sensor is left as it is to reduce power consumption.

That is, the sensor has a part for performing a detection operation and a part for displaying an operation state which is not directly related to the detection. Therefore, in the first step, the power supply to the part that is not directly related to the detection such as the display of the operating state is cut off, and in the second step, the power supply including the detection part is cut off.

In addition, when an intruder is detected, a sensor equipped with a light (flash) for photographing an image needs to temporarily consume a large amount of electric power, so that the charging section inside the sensor is charged in advance. May be done. In such a case, the charging of the charging unit may be stopped by the partial standby signal.

Next, a series of operations of power supply control at the time of power failure in the monitoring device 100b configured as described above will be described. FIG. 6 is a flowchart showing a first operation example of the monitoring device according to the second exemplary embodiment of the present invention. Normally, the monitoring operation by the power supply from the external power supply 110 is performed for all the sensors connected to this apparatus (step S41), and it is always determined whether or not there is a power failure (step S42). That is, the power failure detection unit 108 checks the power supply state from the external power supply 110 in the normal monitoring state of all the sensors.

When it is determined in step S42 that a power outage has occurred for some reason, the battery 107 is switched to backup power supply (step S4).
3). Further, from the control signal output section 150, the connection terminal section 16
A start / standby signal is output to the sensors 161a to 161c via 0 (step S44). At this time, the sensor is designated by the address assigned to the sensor in advance. That is, similarly to the first embodiment, the standby signal is output to the sensor with the low priority according to the predetermined priority. Then, it shifts to a standby state (sleep mode) (step S45).

After that, it is judged whether or not the power failure state is restored (step S46), and if it is restored, step S4.
Returning to 1, the normal monitoring operation is performed. Hereinafter, such an operation is repeated by checking the power failure state by the power failure detecting unit 108 and according to the check result.

FIG. 7 is a flowchart showing a second operation example of the monitoring device according to the second embodiment of the present invention. First, similar to FIG. 6, all the sensors 1 connected to the device are
The 61a to 161c are monitored by the power supply from the external power supply 110 (step S51), and it is constantly determined whether or not there is a power failure (step S52). That is, the external power supply 1 in the normal monitoring state by all the sensors
Check the status of power supply from 10.

If it is determined in step S52 that a power failure has occurred for some reason, the battery 107 is switched to backup power supply (step S5).
3). Furthermore, the timer 105 measures the power failure time,
It is determined whether a predetermined time has passed (step S5).
4). Here, if the power is out of the state even after the lapse of a predetermined time, the control signal output unit 150 outputs the start / standby signal to the sensors 161a to 161c via the connection terminal unit 160 (step S55). At this time, the sensor is designated by the address assigned to the sensor in advance. That is, similarly to the first embodiment, the standby signal is output to the sensor with the low priority according to the predetermined priority. Then, it shifts to a standby state (sleep mode) (step S56).

After that, it is judged whether or not the power failure state is restored (step S57), and if it is restored, step S5.
Returning to 1, the normal monitoring operation is performed. Hereinafter, such an operation is repeated by checking the power failure state by the power failure detecting unit 108 and according to the check result.

As described above, in the case where an arbitrary sensor is put in a standby state after a predetermined time has elapsed from the occurrence of a power failure, the timer 1
In 05, the elapse of the power outage time is measured, and in the short time power outage until the predetermined time elapses, the monitoring operation is continuously performed as usual. On the other hand, in the long time power outage after the predetermined time elapses, By setting the determined sensor in the standby state (sleep mode), the battery 107
It reduces power consumption and realizes long-term monitoring of important objects.

FIG. 8 is a flowchart showing a third operation example of the monitoring device according to the second embodiment of the present invention. First, as in FIG. 6, all sensors connected to the apparatus are monitored by the power supply from the external power source 110 (step S61), and it is constantly determined whether or not there is a power failure (step S62). . That is, the state of power supply from the external power supply 110 is checked in the normal monitoring state of all the sensors.

When it is determined in step S62 that a power outage has occurred for some reason, the battery 107 is switched to backup power supply (step S6).
3). Further, the battery 107 is detected by the capacity detection unit 109.
The remaining amount of is detected and it is determined whether the capacity is less than or equal to a predetermined value (step S64). Here, if the capacity of the battery 107 is less than or equal to a predetermined value, the second standby mode determined in advance is entered (step S65), and if the battery capacity is sufficient, the first standby mode is entered (step S66). Or, perform normal monitoring mode. Note that the first standby mode consumes more power than the second standby mode and may be selected stepwise, and in some cases the first standby mode may be the normal monitoring mode. . That is, the first standby mode is the second
The first standby mode may be the normal monitoring operation if it is located between the standby mode and the normal monitoring operation and is almost the same as the normal monitoring operation.

That is, in the second standby mode of step S65, the standby mode signal is sent to the sensor having the lower priority according to the predetermined priority to enter the sleep mode.

After that, it is judged whether or not the power failure state is restored (step S67), and if it is restored, step S6.
Returning to 1, the normal monitoring operation is performed. On the other hand, step S
In 67, when the power failure is not restored, the process returns to step S64 and the subsequent operations are executed. Hereinafter, such an operation is performed by detecting the power failure state by the power failure detecting unit 108, further detecting the capacity of the battery 107 which is the backup power source by the capacity detecting unit 109, and repeatedly executing it according to the detection result.

Therefore, when the capacity of the battery 107 used as a backup power source is detected by the capacity detecting unit 109 and the predetermined sensor is put in the standby state when the remaining amount of the battery 107 becomes less than the predetermined value, the capacity of the battery 107 is changed. If there is a margin, monitoring can be performed normally in a relatively low power consumption monitoring system, or by shifting to the first standby mode, which consumes less power than usual, monitoring close to normal Can be done. When the power consumption is large or the battery 107 is not sufficiently charged, the power consumption is suppressed early by switching to the second standby mode determined in advance, and the monitoring of important objects is prolonged. It can be done in time.
