Description

  The present invention relates to an earthquake warning device and an earthquake countermeasure system for predicting an incoming seismic wave in advance based on information about an earthquake obtained by observing an earthquake and securing an emergency contact line before the seismic wave arrives. About.

  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 a seismic observation network arranged nationwide and a central organization that supervises earthquake information, and transmits real-time information observed by each seismic observation network to the receiving section of the central organization. The real-time information sent from the observation network is the earthquake data received by the receiver, including the original data, earthquake parameter information (three elements of the earthquake: location, time, magnitude) such as strength and arrival time that can be used for disaster prevention. 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 a preset lower limit intensity, the arrival predicted 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).

  By the way, when a disaster such as an earthquake occurs, outgoing calls and incoming calls are more concentrated in the affected area than usual, which may result in congestion exceeding the processing capacity of the exchange. In a conventional fixed telephone exchange, it has been proposed to restrict outgoing calls as a countermeasure against congestion when the usage rate of a call processor in the exchange exceeds a threshold value for a certain time or more (Patent Document 3).

JP 2003-66152 A JP 2006-112999 A JP 2000-36866 A

  Conventionally, when an earthquake occurs, outgoing and incoming calls are concentrated more than usual, so that the exchange is congested, a failure occurs in the telephone network itself, and an overall communication failure occurs.

  In particular, since the mobile phone terminal is highly portable, there is a characteristic that if the terminal moves and concentrates in a specific area, it is limited by the number of wireless lines and is not easily connected. In addition, in order to restrict incoming calls into an area by using a mobile phone switchboard, it is necessary to check with the service control station to determine which area each mobile terminal is in, so the confirmation processing to the control station also increases. However, the influence has spread to other telephone networks, and the total amount of all telephone networks has been regulated.

  In Patent Document 3, in order to avoid the influence on the entire telephone network, outgoing calls are restricted on the exchange, but when one exchange performs outgoing call restriction processing as a countermeasure against congestion, calls are concentrated on other exchanges. There was a problem that congestion was spreading. In addition, if outgoing calls are restricted, only a certain amount of communication can be connected after all, making communication difficult and making it difficult to contact.

  However, in the event of an earthquake, there was a strong demand for communication to confirm the safety of family members, relatives, friends, acquaintances, staff, employees, and others.

  Therefore, an object of the present invention is to provide an earthquake alarm device and an earthquake countermeasure system provided with an emergency contact means that is more easily connected to a line when an earthquake occurs.

  The earthquake alarm device of the present invention is connected to a line through which information relating to an earthquake is transmitted, has a processing unit, and a telephone device interface unit connected to individual or plural terminal devices, and at least one emergency contact Threshold values related to the destination and earthquake intensity are set in advance, and the processing unit receives the information related to the earthquake, and the earthquake intensity or predicted intensity in the area where the emergency contact is located is the threshold value. The terminal device is controlled via the telephone device interface unit, and an emergency contact located in an area exceeding the threshold is called from the terminal device to secure an emergency contact line. It is characterized by doing.

  In the earthquake alarm device, the processing unit obtains an earthquake intensity or predicted intensity at the location of the emergency contact based on the information on the earthquake, and the obtained earthquake intensity or predicted intensity exceeds the threshold value. It may be determined whether or not an emergency contact located in an area exceeding the threshold value may be obtained, or an area where the earthquake intensity or predicted intensity exceeds the threshold value based on the information on the earthquake And determining whether or not the area where the emergency contact is located corresponds to the determined area, and obtaining the emergency contact located in the area exceeding the threshold.

  Further, the earthquake countermeasure system of the present invention includes a line through which information relating to an earthquake is transmitted, an earthquake alarm device connected to the line, and individual or plural terminal devices connected to the telephone device interface unit of the earthquake alarm device. The earthquake alarm device has at least one emergency contact and a threshold value relating to the intensity of the earthquake set in advance, receives information about the earthquake transmitted from the line, and receives the emergency contact When the earthquake intensity or predicted intensity in the area where the location is exceeded exceeds the threshold, the terminal device is controlled via the telephone device interface unit, and the emergency contact located in the area exceeding the threshold The terminal device is called to secure an emergency contact line.

  Here, in the earthquake countermeasure system, the earthquake warning device obtains an earthquake strength or predicted strength in an area where the emergency contact is located based on the information on the earthquake, and the obtained earthquake strength or predicted strength is It may be determined whether or not the threshold value is exceeded, and an emergency contact located in an area that exceeds the threshold value may be obtained. An area that exceeds the threshold may be obtained, and it may be determined whether the area where the emergency contact is located corresponds to the obtained area, and an emergency contact located in the area that exceeds the threshold may be obtained. .

  Furthermore, in the earthquake countermeasure system, the terminal device has a plurality of lines, and the earthquake warning device has a plurality of emergency contact points set in advance, and uses one of the plurality of lines in advance. Call one of the set emergency contacts from the terminal device, and use the other one of the lines to call another preset emergency contact from the terminal device. Also good.

  According to the present invention, when the earthquake warning device or its processing unit receives information about an earthquake, and the earthquake intensity or predicted intensity in the area where the emergency contact is located exceeds the threshold, the telephone device interface unit The terminal device can be controlled via the terminal, and an emergency contact located in an area exceeding the threshold value can be called from the terminal device to secure an emergency contact line. You can inquire about the safety of emergency contacts in your area. In the case of predicted strength, an earthquake has occurred in the epicenter, but it is possible to secure an emergency contact line even when an earthquake wave has not yet arrived in the area where the emergency contact is located. When the emergency contact is connected via the telephone network, the line can be secured before being affected by congestion or communication restrictions.

  FIG. 1 is a block diagram conceptually showing the structure of an earthquake countermeasure system 10 of the present invention.

  In FIG. 1, an earthquake countermeasure system 10 includes a line 11 on which information relating to an earthquake is transmitted, an earthquake alarm device 12 connected to the line 11, and individual or plural units connected to a telephone device interface unit 22 of the earthquake alarm device 12. Terminal device 13. Further, the terminal device 13 is connected to the telephone network 14.

  The line 11 is directly or indirectly connected to the earthquake warning device 12 and is used to transmit information related to the earthquake to the earthquake warning device 12 from a distribution source (not shown). The line 11 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, and wireless LAN. Lines such as (Local Area Network), CS (Communication Satellite) broadcasting, and mobile phones can be used. The line 11 can also be used as the line 15 that connects the terminal device 13 and the telephone network 14 (in FIG. 1, an example of separate lines is described). In this case, the line connected to the outside may be branched into the line 11 and the line 15 by a router or the like.

  Information related to earthquakes transmitted through the line 11 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 predicted arrival of the earthquake in the area where the earthquake warning device 12 is installed For example, information on the remaining time until the time. Note that disaster information other than earthquakes may be notified through the line 11.

  The earthquake alarm device 12 includes a processing unit 21 and a telephone device interface unit 22, and further includes a memory 23. The line 11 is connected to the terminal device 13 via the telephone device interface unit 22. And thresholds for at least one emergency contact and earthquake intensity are preset.

  Furthermore, the earthquake alarm device 12 may itself comprise a notification means such as a speaker, a display, a lamp. Further, various devices and the earthquake alarm device 12 may be connected for disaster prevention, and control may be performed so as to avoid danger before the earthquake reaches. 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 12. The processing unit 21 receives at least information about the earthquake transmitted from the line 11 and sends the terminal device 13 via the telephone device interface unit 22. Then, a call signal is transmitted from the terminal device 13 to a preset emergency contact address, and an emergency contact line is secured. Furthermore, the process part 21 may produce | generate alerting information based on the information regarding an earthquake. Further, the processing unit 21 can obtain the earthquake intensity or predicted intensity in the area where the earthquake warning device is installed or in other areas based on the information on the earthquake, and whether the obtained intensity or predicted intensity exceeds the threshold value. It can be determined whether or not. The earthquake warning device 12 can be incorporated in the terminal device 13 so that the processing unit of the terminal device 13 can also be used as the processing unit 21 of the earthquake warning device 12.

  Pre-set emergency contact information includes, for example, personal terminal devices such as family members, relatives, friends, acquaintances, staff, and employees, and terminal devices of organizations such as police, fire stations, hospitals, government offices, and companies. It is recorded in the memory of the device 12 or the terminal device 13. As a terminal device for emergency contact, a communication terminal such as a fixed telephone, a facsimile, a mobile phone, and a personal handyphone system (PHS), a computer having a communication function, and the like can be used. If the emergency contact is an external communication terminal, a telephone number is recorded, and if it is an extension, the extension number is recorded in a memory or the like.

  The emergency contact information may be only one place or a plurality of places. As will be described later, a terminal device located in a disaster area can be used as an emergency contact. In this case, all telephone numbers recorded in the terminal device are emergency contacts. In the case of setting a plurality of emergency contacts, a priority order for contacting may be set. For example, priorities may be set according to the importance of emergency contacts, priorities may be set in descending order from the epicenter of the earthquake, or priority will be given in descending order of earthquake intensity in the area where the earthquake is located. The ranking may be set higher.

  Moreover, it is preferable to be able to identify the area where the emergency contact is located. In this case, regional information such as an address may be recorded together with the telephone number or extension number of an emergency contact in a memory or the like, and if it is a fixed telephone, an approximate area can be specified from the area code. In the case of a mobile communication terminal, an area where the communication terminal is likely to be used may be recorded in advance as an area where the emergency contact is located.

  The threshold relating to the intensity of the earthquake is the intensity of the earthquake that is a problem for the setter. For example, when the earthquake countermeasure process is executed when the seismic intensity is 3 or more, the threshold is set to seismic intensity 3. That's fine.

  The telephone device interface unit 22 is for connecting to the terminal device 13, and transmits a control signal for controlling the terminal device 13, notification information, and the like in a format corresponding to the terminal device 13. When the terminal device 13 has a button telephone compatible input unit, the telephone device interface unit 22 may connect a transmission circuit having a control signal line and an audio signal line to the input unit of the terminal device 13. When the terminal device 13 has a single-phone compatible input unit, the telephone device interface unit 22 needs a circuit that forms a loop with the terminal device 13 and a circuit that converts digital notification information and the like into analog. When the earthquake warning device 12 is incorporated in the terminal device 13 and the processing unit of the terminal device 13 is also used as the processing unit 21 of the earthquake warning device 12, the physical telephone device interface unit 22 does not exist, but in the processing unit Thus, there is an electronic telephone device interface unit that connects the function of the earthquake alarm device 12 and the function of the terminal device 13.

  The memory 23 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. In addition, the memory 23 may record an emergency contact information, an installation area of the emergency contact information, or a threshold value. Note that the earthquake alarm device 12 can be integrated into the terminal device 13 so that the memory of the terminal device 13 can also be used as the memory 23 of the earthquake alarm device 12.

  The terminal device 13 is connected to the telephone network 14 by a line 15 and uses a communication terminal such as a local terminal control device, a fixed telephone, a facsimile, a mobile phone, a personal handyphone system (PHS), and a computer having a communication function. Can do.

  The local terminal control device is an apparatus that accommodates individual or plural terminal devices arranged on the premise and controls at least the individual or plural local terminal devices. 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 a system.

  In FIG. 1, there is one terminal device 13, but the earthquake warning device 12 may be connected to a plurality of terminal devices 13 and have a plurality of lines 15. In addition, one terminal device 13 may have a plurality of lines 15 such as a local terminal control device.

  The telephone network 14 is an existing telephone network. The telephone network includes a public telephone network, ISDN (abbreviation of Integrated Service Digital Network), ADSL (Asymmetric Digital Subscriber Line), CATV (Community An antenna television network, an optical fiber network, a wireless LAN (Local Area Network), a CS (Communication Satellite) broadcast, a mobile telephone network, and the like can be used.

  Next, with reference to FIG. 2 and FIG. 3, one of the earthquake countermeasure processing of the earthquake countermeasure system using the earthquake warning device of the present invention will be described. FIG. 2 is a flowchart of an earthquake countermeasure process for performing a contact process to an emergency contact address installed in a disaster area by the earthquake countermeasure system, and FIG. 3 is a diagram showing a connection sequence at the time of the earthquake countermeasure process. The leftmost column in FIG. 3 is a distribution source 41 of information related to earthquakes, and the rightmost column is an emergency contact 42.

  First, in step 11 (S1), information 43 relating to the earthquake is transmitted from the distribution source 41 to the earthquake warning device 12 through the line 11, and the earthquake countermeasure process is started.

  In step 12 (S12), the processing unit 21 of the earthquake warning device 12 specifies the area where the preset emergency contact address 42 is located. The area where the emergency contact 42 is located can be specified from the area information recorded in the memory or the like, the area code of the telephone number of the emergency contact, or the like. Here, when a plurality of emergency contacts are set, it is preferable to start from an emergency contact with a high priority.

  In step 13 (S13), the earthquake intensity or predicted intensity in the area where the emergency contact address 42 is located is calculated based on the information 43 about the earthquake. However, if the information about the earthquake already includes information on the intensity of the earthquake or the predicted intensity in the area where the emergency contact is located, step 13 is not necessary.

  Further, in step 14 (S14), it is determined whether the earthquake intensity or predicted intensity in the area where the emergency contact 42 is located is smaller or larger than a preset threshold value. If it is larger, the process proceeds to step 15. If it is smaller, the emergency contact is not contacted. If a plurality of emergency contacts are set and there is another emergency contact, the processes of steps 12 to 14 are performed for the next emergency contact. For all emergency contacts, if the area where the earthquake is located has an earthquake intensity or predicted intensity lower than the threshold value, the process ends.

  In step 15 (S15), the earthquake warning device 12 sends an earthquake countermeasure activation signal 44 to the terminal device 13. The earthquake countermeasure activation signal 44 causes the terminal device 13 to execute earthquake countermeasure processing, and is sent to the terminal device 13 via the telephone device interface unit 22 of the earthquake warning device 12.

  In step 16 (S 16), the terminal device 13 that has received the earthquake countermeasure activation signal 44 sends a call signal 45 to the emergency contact address 42. The terminal device 13 reads the telephone number or extension number of the emergency contact address 42 recorded in the memory or the like of the earthquake warning device 12 or the terminal device 13, and calls the telephone number or extension number of the emergency contact address 42 from the terminal device 13. Signal 45 is sent out.

  In step 17 (S17), it is determined whether or not there is a response 46 from the emergency contact 42. If there is no response 46, the call is made again. If there is a response 46, the line is secured in step 18 (S18). In step 19 (S19), the operation ends.

  The reserved line is normally connected as long as the terminal device 13 or the emergency contact terminal device does not hang up the telephone, so the line may be maintained until emergency communication or safety can be confirmed, After securing the emergency contact and the line, the terminal device 13 may send an emergency message 47 to the emergency contact.

  The emergency message 47 may be a response message recorded in the memory of the earthquake warning device 12 or the terminal device 13 or a message including notification information generated by the earthquake warning device 15 from the information 43 about the earthquake. For example, in the case of the former, a response message “It is predicted that an earthquake will occur. Please keep the line for a while” is reproduced from the memory.

  In the latter case, the information on the epicenter, occurrence time, and magnitude of the earthquake, the predicted strength of the earthquake, the maximum speed, the maximum acceleration, the maximum displacement, the predicted arrival time, or the arrival in the area where the emergency contact 12 is located as the notification information Information related to the remaining time until the predicted time (hereinafter referred to as “predicted intensity information etc.”) may be included in the message. The information obtained in step 13 can be used as the predicted strength information in the emergency contact 42. For example, a message “An earthquake of seismic intensity XX is predicted to occur in XX seconds later” and a message 47 “An earthquake of seismic intensity XX occurred in XX area on XX month, XX day, XX hour, XX” Can be sent out.

  The message including the notification information is sent to the terminal device 13 via the telephone device interface unit 22 and a message corresponding to the notification information recorded in the memory 23 of the earthquake warning device 12 is sent from the terminal device 13 for emergency communication. The information may be sent to the destination 42, or the notification information is sent from the earthquake warning device 12 to the terminal device 13, and the terminal device 13 reproduces the message corresponding to the notification information in the memory and sends it to the emergency contact 42 May be.

  Thus, according to the earthquake countermeasure system 10 using the earthquake warning device 12 of the present invention, when the earthquake warning device 12 receives the information 43 about the earthquake, a call signal is sent to the emergency contact information registered in advance. Since it can be sent, an emergency contact line can be secured at an earlier stage. In some cases, an earthquake has occurred in the epicenter, but it is possible to secure an emergency contact line even when an earthquake wave has not yet reached in the area where the emergency contact address 42 is located. If the terminal device of the emergency contact 42 is a communication terminal such as a fixed telephone, a facsimile, a mobile phone, and a personal handyphone system (PHS) connected via the telephone network 14 and a computer having a communication function, congestion or communication Lines can be secured before being affected by regulations.

  In addition, when there is a response from the emergency contact, the emergency contact can be prepared for an earthquake by sending a message including notification information generated based on information about the earthquake through the terminal device. It is preferable because appropriate disaster prevention measures against earthquakes can be taken.

  Further, when the terminal device 13 connected to the earthquake warning device 12 has a plurality of lines 15, the earthquake warning device 12 uses one of the plurality of lines 15 to issue the emergency contact 42 from the terminal device 13. It is also possible to make a call and use another one of the plurality of lines 15 to make a call to another preset emergency contact. In this case, a plurality of emergency contacts are recorded in the memory of the earthquake warning device 12 or the terminal device 13. Furthermore, in addition to a plurality of emergency contacts, a priority order for contacting may be set.

  When the terminal device 13 has a plurality of lines 15, a plurality of terminal devices 13 may be connected to the earthquake warning device 12 to have a plurality of lines 15, or a single terminal device 13 may have a plurality of lines 15. The line 15 may be provided. If a plurality of terminal devices 13 are connected, the earthquake warning device 12 controls one terminal device 13 so that a call signal is sent from one of the lines to the emergency contact point. The terminal device 13 can be controlled to send a call signal from another line to another emergency contact. When one terminal device 13 has a plurality of lines 15, for example, after a call signal is sent from the terminal device 13 to a certain emergency contact, the line is put on hold and another line is used. A call signal may be sent to the emergency contact address.

  2 and 3, the earthquake countermeasure process controls the terminal device when the earthquake intensity or predicted intensity in the area where the emergency contact is located exceeds the threshold value in steps 12 to 14, and Since the call is made from the terminal device, the contact process can be performed to the emergency contact address installed in the disaster area.

  FIG. 4 is another embodiment of the flowchart of the earthquake countermeasure process for performing the contact process to the emergency contact address installed in the stricken area. Also in FIG. 4, the earthquake countermeasure system 10 of FIG. 1 is used.

  First, in step 21 (S21), information relating to an earthquake is transmitted from the distribution source to the earthquake warning device 12 through the line 11, and earthquake countermeasure processing is started.

  In step 22 (S22), the processing unit 21 of the earthquake warning device 12 calculates the earthquake intensity or predicted intensity in each region based on the information related to the earthquake. However, if the information on the earthquake already includes information on the intensity of the earthquake or the predicted intensity in each region, step 22 is not necessary. Here, each area for obtaining the earthquake intensity or the predicted intensity may be set in advance or nationwide. When the area is set in advance, at least the area where the emergency contact is located is included. If a plurality of emergency contacts are set, the area where each emergency contact is located may be registered. The nationwide earthquake intensity or predicted intensity can predict a rough intensity distribution based on the earthquake intensity at the epicenter and the distance from the epicenter.

  In step 23 (S23), it is determined whether the earthquake intensity or the predicted intensity is smaller or larger than a preset threshold value for each area. If it is larger, the process proceeds to step 24. Determine the intensity of earthquake or predicted intensity.

  In step 24 (S24), the presence / absence of an emergency contact located in an area equal to or greater than the threshold value is confirmed. If there is an emergency contact, the process proceeds to step 25; To 24 (S22 to S24) are performed. The processing of steps 22 to 24 (S22 to S24) confirms whether or not there is a damaged area that is greater than or equal to the threshold value, and if there is a damaged area that is larger than the threshold value, the emergency located in the damaged area Processing to contact the contact.

  Steps 25 to 29 (S25 to S29) are basically the same as steps 15 to 19 in FIG. If a plurality of emergency contacts are located in an area that is equal to or greater than the threshold, after securing the line in step 28, the other steps are used for other emergency contacts using the other lines. It is preferable to carry out. In addition, when there is an emergency contact address installed in another area, the processing after step 22 may be executed.

  When using emergency contact processing as shown in Fig. 4, for example, check the distribution of earthquake intensity or predicted intensity nationwide, and install all telephone numbers recorded in the terminal device in areas above the threshold. It is also possible to send a call signal to a telephone number installed in an area equal to or greater than a threshold value. In this case, all the telephone numbers recorded in the terminal device correspond to the emergency contact address.

  In addition, this invention is not limited to the thing of the said embodiment, A various change is possible as needed. For example, the area may be recorded for only a part of the emergency contact, not the entire emergency contact, and the emergency contact processing of the present invention may be performed for the emergency contact recorded for the part of the area.
