Description

  The present invention relates to an earthquake alarm device and an earthquake notification system for notifying an incoming earthquake wave in advance based on information about an earthquake obtained by observing an earthquake and taking measures for disaster prevention before the earthquake wave arrives.

  In recent years, there has been proposed a system that informs of the predicted strength of an earthquake and the predicted arrival time (time), supports the preparation of a kite against an earthquake, and prevents disasters (Patent Document 1).

  This system is composed of an earthquake observation network arranged nationwide and a central organization that supervises earthquake information, and transmits real-time information observed by each earthquake observation network to the receiving section of the central organization. Real-time information sent from the observation network is earthquake parameter information (three elements of the earthquake: location, time, magnitude) such as the original data, strength that can be used for disaster prevention, arrival time, etc. Three elements are obtained by the analysis unit.

  Then, it is determined whether or not the JMA seismic intensity scale is, for example, a magnitude that gives a value of 5 or more in a specific location, and whether or not the epicenter distance in the specific location is within a sensitive radius determined from the magnitude. In addition, the prediction calculation unit calculates the standard intensity at the specific location from the epicenter distance, magnitude, and depth, as well as the amplification factor at the specific location due to the geological situation of the place of earthquake motion, the difference in the structure of the building, etc. Using the standard intensity and the amplification factor, the seismic parameters of the seismic intensity such as the predicted intensity of the seismic wave (S wave) or the maximum velocity, maximum acceleration, maximum displacement, and predicted arrival time are obtained.

  When the obtained predicted intensity exceeds the preset lower limit intensity, the arrival prediction time and the predicted intensity are notified (displayed) based on the propagation speed of the seismic wave (P wave, S wave).

  In addition, as a seismic alarm device that can issue alarms with a simpler configuration, the seismometer installation location (your own station), after observing the P wave from the measured original data, before the arrival of the S wave An earthquake warning device has also been proposed that issues a warning by estimating the degree of damage (such as seismic intensity) (Patent Document 2).

  Furthermore, by using neural networks, it is possible to evaluate not only the earthquake early warning but also the ground period and the vibration characteristics of the building with high accuracy, and the reliability of prediction is dramatically improved by optimizing the neural network through learning. An earthquake disaster prevention system has been proposed (Patent Document 3).

And a plurality of local terminal devices 15 accommodated in the network.

  The facility 11 is an area such as a building, a business office, or a factory where the earthquake warning device 13 is installed and earthquake information is notified by the earthquake notification system 1. One earthquake notification system 1 may notify the entire building, business office, factory, or the like, or may notify only a part of the building, business office, factory, or the like.

  The line 12 connects the outside and the earthquake warning device 13 directly or indirectly, and is used to transmit information on the earthquake to the earthquake warning device 13 from the outside of the facility 11. The line 12 includes a dedicated line, a public telephone network, ISDN (abbreviation of Integrated Service Digital Network), ADSL (Asymmetric Digital Subscriber Line), CATV (Community Antenna TeleVision) network, optical fiber, wireless LAN. Lines such as (Local Area Network), CS (Communication Satellite) broadcasting, and mobile phones can be used. The line 12 can also be used as the line 17 that connects the local terminal control device 14 and the outside. In this case, the line connected to the outside may be branched into the line 12 and the line 17 by a router or the like.

  Information on earthquakes transmitted through the line 12 is observation results observed by sensors installed in various places, or calculation results based on the observation results. Obtain information sent from the Japan Meteorological Agency or the Meteorological Agency. It is distributed from a distribution source such as a distribution company that distributes through a line. As information about the earthquake, for example, information on the location, time, and magnitude that are the three elements of the earthquake, and the predicted strength, maximum speed, maximum acceleration, maximum displacement, predicted arrival time or arrival prediction of the earthquake in the area where the earthquake warning device 13 is installed For example, information on the remaining time until the time. In addition, disaster information other than earthquakes may be notified through the line 12.

  As shown in FIG. 2, the earthquake alarm device 13 includes a processing unit 21, a memory 22, a telephone device interface unit 23, and a power supply unit 24, and the line 12 is connected to the processing unit 21.

Furthermore, the earthquake warning device 13 may include a notification means such as a speaker, a display, and a lamp. In addition, various devices and the earthquake alarm device 13 may be connected for disaster prevention, and control may be performed to avoid danger before the earthquake arrives. For example, it is preferable to control to perform disaster prevention processing by being connected to an elevator, a factory device, a gas or fuel supply device, a hospital life support device, or the like.

  The processing unit 21 is a CPU (Central Processing Unit) that controls the operation of the earthquake warning device 13, and at least processes information related to the earthquake transmitted from the line 12 to generate notification information.

  As the content of the notification information, information regarding the earthquake may be used as it is, or a result calculated based on the information regarding the earthquake may be used as the notification information. For example, if the information about the earthquake is information about the predicted strength, maximum speed, maximum acceleration, maximum displacement, predicted arrival time or remaining time until the predicted arrival time of the earthquake in the area where the earthquake warning device 13 is installed, It is sufficiently effective to notify one or several as it is as notification information. In addition, even if the information about the earthquake is only information about the place, time, and magnitude of the earthquake, it is necessary to take disaster prevention measures against the earthquake simply by notifying one or several of the information as notification information. Can do. However, when the information on the earthquake is information on the location, time, and magnitude of the earthquake, the processing unit 21 based on the information, the predicted strength, maximum speed of the earthquake in the area where the earthquake warning device 13 is installed, It is preferable to calculate the maximum acceleration, the maximum displacement, the predicted arrival time, or the remaining time until the predicted arrival time, and to include one or several of the information in the notification information, since it is possible to prepare for an earthquake.

  The memory 22 stores voice information transmitted as notification information, information when the processing unit 21 calculates, and the like, and is used when the processing unit 21 generates notification information.

  The telephone device interface unit 23 is connected to the local terminal control device 14 through the line 16 and is for connecting to the telephone device such as the local terminal control device 14 and the local terminal device 15. A control signal, notification information, and the like for control are transmitted in a format corresponding to the telephone device.

  When the local terminal control device 14 has a button telephone compatible input unit, the telephone device interface unit 23 may connect a transmission circuit having a control signal line and a voice signal line to the input unit of the local terminal control device 14. . When the local terminal control device 14 has an input unit compatible with a single telephone, the telephone device interface unit 23 needs a circuit that forms a loop with the local terminal control device 14 and a circuit that converts digital notification information and the like into analog. It becomes.

  The power supply unit 24 supplies power to the processing unit and the like of the earthquake alarm device 13, and is preferably an uninterruptible power supply so as to operate even during a power failure. In FIG. 2, supplying power to the processing unit 21 is indicated by an arrow, but is merely an example, and power is not supplied only to the processing unit 21.

  The local terminal control device 14 is connected to an external telephone network via a line 17 and accommodates individual or plural local terminal devices arranged in the facility 11 and controls at least the individual or plural local terminal devices. It is a device to do. Examples of the private terminal control device include a key telephone main device, a cordless telephone main device, a PHS main device, a private branch exchange (PBX), and an IP-PBX.

  Each main unit controls several to a few dozens of small to medium-sized local terminal devices, accommodates the lines of multiple local terminal devices, and is connected to an external telephone network. It is a device that controls functions such as telephone and extension transfer. A private branch exchange is also called a PBX (Private Branch eXchange), and is generally installed in a company, a store, or the like, and is a device for controlling each function such as extension call / transfer and connection to an external public telephone network. IP-PBX is a PBX compatible with IP (Internet Protocol), and provides an IP telephone network constructed on an IP network with a function for connecting and controlling an extension telephone or an external public telephone network, Or system.

  The local terminal control device 14 preferably has a paging function for simultaneously calling a plurality of local terminal devices 15.

In addition, when the local terminal device 15 has a local broadcasting facility, the broadcast information can be broadcast simultaneously using the local broadcasting facility.

  The plurality of local terminal devices 15 are telephones, speakers, local broadcasting facilities, and the like, and function as means for informing notification information from the earthquake warning device 13 when an earthquake occurs.

  Next, with reference to FIG.3 and FIG.4, the alerting | reporting operation | movement using the earthquake warning device of this invention is demonstrated. FIG. 3 is a flowchart showing a notification operation using the earthquake alarm device 13, and FIG. 4 is a diagram showing a connection sequence during the notification operation. The leftmost column in FIG. 4 is a distribution source 41 of information related to earthquakes.

  First, in step 1 (S1), the notification operation is started when the processing unit 21 of the earthquake warning device 13 receives the information 42 transmitted from the distribution source 41 and transmitted through the wiring 12.

  In step 2, the processing unit 21 of the earthquake warning device 13 determines the contents of the information 42 (S2). In FIG. 3, it is determined in step 2 (S2) whether or not the information 42 is information related to an earthquake. If the information 42 is information related to an earthquake, the process proceeds to the next step 3 (S3). In the case of other information, a notification operation corresponding to the information is performed. However, in FIG. 3, the process proceeds to step 11 (S11) to step 13 (S13), and a notification operation for notifying other information is performed. ing. Other information includes tsunami information, cancellation information, and training information. In the case of tsunami information, the tsunami information may be notified as notification information. The cancellation information is information for canceling the notification if the information 42 about the earthquake is a false report. The training information is for training and operation confirmation. Steps 11 (S11) to 13 (S13) are operations corresponding to steps 5, 6, and 7, respectively.

  When the information related to the earthquake is received, in step 3 (S3), the processing unit 21 of the earthquake warning device 13 predicts the predicted earthquake intensity, maximum speed, maximum acceleration, maximum displacement based on the information 42 related to the earthquake. The arrival prediction time or the remaining time until the arrival prediction time is calculated. However, Step 3 is not necessary when the information 42 relating to the earthquake already includes information such as predicted strength.

  In step 4 (S4), it is determined whether the predicted intensity of the earthquake in the installation area is smaller or larger than a preset threshold value. Here, the threshold value is the intensity of the earthquake in question in the facility. For example, when the notification is made when the seismic intensity is 3 or more, the threshold value may be set to seismic intensity 3. Without setting a threshold, it is possible to always notify regardless of the intensity of the earthquake. If no threshold is set, step 4 is not necessary.

  In step 5 (S5), the control signal 45 is sent from the earthquake warning device 13 to the local terminal control device 14 through the link (communication path) 44 between the earthquake warning device 13 and the local terminal control device 14. The control signal 45 controls the local terminal control device 14 to cause the local terminal control device 14 to send a terminal control signal 46 to the local terminal device 15, and to establish a link 47 between the earthquake alarm device 13 and the local terminal device 15. It is for forming.

  As the control signal 45, for example, a paging function activation signal is transmitted, the paging function of the local terminal control device 14 is activated, the terminal control signals 46 are simultaneously transmitted to a plurality of local terminal devices 15, and a plurality of local sites are simultaneously transmitted. A link with the terminal device 15 may be formed. Further, as the control signal 45, a local terminal device activation signal may be sent to the individual local terminal device 15 to form a link with each local terminal device 15. In the case of sending a local terminal device start signal, if a local broadcast facility start signal for selecting and starting a local broadcast facility is sent as the local terminal device 15, a link with the local broadcast facility is formed, and the local broadcast facility is used. Broadcast information can be broadcast over a wide area.

  As the terminal control signal 46, it is possible to use a speaker amplifier activation signal, a display activation signal for displaying display data, a signal for sounding a lamp, a signal for generating an alarm sound, etc. in order to notify audio information from the speaker. it can.

  If the link 44 is not formed between the earthquake warning device 13 and the local terminal control device 14 prior to step 5, the call signal 43 is sent to the local terminal via the telephone device interface unit 23 of the earthquake warning device 13. It transmits to the control apparatus 14, and the link 44 is formed.

  In step 6 (S 6), a link 47 is formed between the earthquake warning device 13 and the local terminal device 15 by the control signal 45 and the terminal control signal 46.

  In step 7 (S7), the notification information 48 is generated based on the information 42 about the earthquake received by the processing unit 21 of the earthquake warning device 13, and the notification information 48 is converted into a plurality of information via the telephone device interface unit 23 and the link 47. It is sent to the local terminal device 15. The notification information 48 is voice information for notifying information relating to an earthquake by voice, display data for display on a display, ringing data for ringing a speaker and a lamp, signal data for generating a warning sound, and the like. The processing unit 21 reads out voice information, display data, ringing data, signal data, and the like corresponding to information related to the earthquake and information calculated from the information related to the earthquake from the memory 22 and, if necessary, links 47 in the telephone device interface unit 23. The information is converted into a format corresponding to the information information 48 and transmitted as notification information 48. For example, as the content of the notification information, the remaining time until the predicted arrival time in the installation area and the predicted strength of the earthquake are adopted, the alarm sound generation data, the warning lamp display data, and the earthquake with seismic intensity XX in XX seconds later May be transmitted as broadcast information. In addition, the location, time, and magnitude of the earthquake are used as the content of the notification information, and the voice information that “An earthquake with a seismic intensity of XX occurred at XX hours and XX. Please note.” It may be sent as information. Then, each local terminal device 15 that has received the notification information 48 notifies the notification information 48 using a speaker, a display, a lamp, or the like.

  In step 8 (S8), after transmitting the notification information 48, the remaining time until the arrival prediction time is counted up and updated to the current remaining time. In other words, the elapsed time is subtracted from the remaining time when the notification information 48 is first transmitted to obtain a new remaining time. For example, if the remaining time when the notification information 48 is first transmitted is 20 seconds, the remaining time is updated to 15 seconds after 5 seconds.

  In step 9 (S9), it is determined whether or not the updated remaining time is greater than 0. If the updated remaining time is larger (No in FIG. 3), the process proceeds to step 7 and the notification operation is repeated again so that the remaining time becomes 0. Then, the notification operation is terminated. Here, when the process proceeds to step 7 and the notification operation is repeated again, it is preferable to include the remaining time updated in step 8 in the notification information. For example, if the remaining time is updated at a predetermined interval, for example, every 5 seconds, and included in the notification information, the disaster prevention effect is further improved.

  In step 10 (S10), transmission of the notification information 48 is stopped, and if necessary, the link is disconnected and the notification operation is terminated. In FIG. 4, the earthquake warning device 13 sends a disconnection signal 49 to the local terminal control device 14 to disconnect the link.

  As described above, in the earthquake alarm device 13 of the present invention, since the notification information 48 can be notified using the existing on-site terminal equipment, the system for notifying earthquake information and warning to the entire facility or building at low cost. Can be obtained.

The data is sent to the loop control unit 35 of the device interface unit 23. The loop control unit 35 closes the circuit 31 and closes the loop, thereby sending a call signal 62 to the local terminal control device 14, and sending a dial tone (DT: Dial Tone) 63 from the local terminal control device 14. The monitoring unit 34 detects the link 44 and forms a link 44 with the local terminal control device 14.
