Description

  The present invention relates to a disaster prevention system that performs predetermined countermeasure actions in response to the occurrence of an earthquake, in particular, from the detection of initial tremor to the arrival of the main movement, at the arrival of the main movement, and after the end of the main movement, respectively. It relates to a disaster prevention system that aims to decrease.

  Conventionally, when an earthquake occurs, the information on the epicenter, the magnitude of the earthquake, the seismic intensity of each place, and the tsunami is broadcast through television and radio broadcasting in order to widely inform the public of the information. However, even when broadcasting through TV and radio in this way, information is provided at the earliest few minutes after the actual earthquake occurs. There is a high possibility that the information will not be utilized.

  Here, shaking due to an earthquake is divided into an initial fine movement called a P wave and a main movement called an S wave. The P wave and S wave are generated simultaneously from the epicenter of the earthquake, and the P wave travels faster in the ground, so the P wave reaches the ground surface first, and the S wave arrives later. Systems that operate between the detection of P waves and the arrival of S waves are being developed using this property of earthquakes.

On the other hand, in disaster prevention systems that generate alarms, etc., by detecting the occurrence of fires or gas leaks, etc., a seismic sensor is installed in the receiver or sensor, and when an earthquake occurs, each sensor is detected by a signal from the seismic sensor A device that increases the sensitivity of a vessel is known (Patent Document 1). Moreover, what makes a gas shut-off valve close when an earthquake is detected is also known (patent document 2).

  Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a system diagram of a disaster prevention system in the present embodiment. As shown in this figure, the disaster prevention system according to the present embodiment connects a receiver 1 to a plurality of seismometers 3 and 3 via a communication network 2, and the receiver 1 further includes an external power line 4, fire and gas leaks. The sensor 5 is connected to the open / close valve 6 a of the gas pipe 6.

  The seismometers 3 and 3 are installed in advance in areas where earthquakes are highly likely to occur. When an earthquake occurs, the seismometers 3 first detect P-waves, which are initial tremors, and estimate the epicenter and the magnitude of the earthquake. The epicenter can be estimated from the difference in arrival time of the P waves in the plurality of seismometers 3 and 3. The magnitude of the earthquake can be estimated from the distance from the seismometer 3 to the epicenter and the magnitude of the P wave. Furthermore, the time from the distance from the epicenter to the installation location of the receiver 1 until the S wave that is the main motion reaches the installation location of the receiver 1 can also be calculated.

  The seismometer 3 transmits the disaster pre-information to the receiver 1 via the communication network 2 when the detected earthquake is larger than a predetermined scale. The disaster prior information includes earthquake scale information and S wave arrival time information at the place where the receiver 1 is installed.

  The receiver 1 includes a transmission / reception unit 10 that receives disaster prior information from the seismometer 3 and transmits information to the outside via the communication network 2. In addition to this, the receiver 1 is further provided with an alarm storage unit 11 that stores information on voice alarms according to scenes, and a geographical information storage unit 12 that stores in advance the geographical information of the place where the receiver 1 is installed. An earthquake history storage unit 13 for storing the history of earthquake occurrence, a seismic sensor 14 for detecting the shaking of the earthquake and specifying the magnitude of the earthquake, and a built-in battery 15 for supplying power to each part of the receiver 1 in the event of a power failure And.

  Furthermore, the receiver 1 reads information stored in the alarm storage unit 11, the geographical information storage unit 12, and the earthquake history storage unit 13 based on information from the transmission / reception unit 10 and the seismic sensor 14, and controls various devices. The control part 20 which performs is provided. The control unit 20 controls the sensor 5 whose sensitivity is changed by the sensitivity switching unit 21, an alarm generation unit 22 that issues a predetermined alarm to the speaker 22 a, and an alarm or the like on the display unit 23 a. A display control unit 23 to be displayed, a valve control unit 24 for performing on / off control of the on-off valve 6a provided in the gas pipe 6, a power monitoring unit 25 for monitoring the presence or absence of an external power source, and a power source switching unit 17 for external power source This is a built-in battery 15 provided.

  The control unit 20 reads out an alarm from the alarm storage unit 11 according to the respective scenes before the main motion arrives, at the time of arrival, and after the completion, and causes the alarm generation unit 22 to issue the alarm. FIG. 2 shows the structure of alarm data stored in the alarm storage unit 11. As shown in this figure, the alarm data is roughly divided into three types before reaching the main motion, when reaching the main motion, and after the end of the main motion.

  The alarm data before reaching the main movement consists of a basic alarm A and an additional alarm B. Basic alarm A is to notify that there is a possibility that an earthquake will occur soon, to confirm the source of fire, and to promote safety, and is always issued before reaching the main movement. . Further, as the additional alarm B, information corresponding to individual circumstances at the installation location of the receiver 1 can be registered in advance.

  Further, among the alarm data before the arrival of the main motion, for the basic alarm A, the contents of each alarm are stored in association with the emergency level information as shown in FIG. The basic alarm A is issued in order from the top shown in FIG. On the other hand, according to the time to reach the main motion, only the alarm contents associated with the urgency information corresponding thereto are actually issued. For example, if the time until the main motion arrives is as short as about 10 seconds, the alarm contents to be issued are 1 and 6, assuming that only the alarm contents corresponding to the urgency information 1 are issued. They are issued in the order of 1,6.

  The alarm data when the main movement is reached consists of a basic alarm C. The basic alarm C notifies the duration of the earthquake. The duration of the earthquake is included in the prior disaster information from the seismometer 3, and the information is combined with the basic alarm C, so that the duration is output as a voice signal when the main movement is reached.

  The alarm data at the end of the main movement consists of a basic alarm D, a tsunami alarm E, a landslide alarm F, and a high-rise house alarm G. The basic alarm D is for prompting evacuation, and guides an evacuation place nearby and how to get to the evacuation place. The tsunami warning E warns that a tsunami may occur when the installation location of the receiver 1 faces the coast, and prompts evacuation to a high ground.

  Furthermore, the landslide warning F warns that there is a landslide risk area when there is a mountain or cliff near the installation location of the receiver 1, and immediately starts evacuation. It is what encourages. And the high-rise house warning G warns that there is a risk of falling objects when the installation location of the receiver 1 is a high-rise house, and supports to stand by in the building.

  Next, the operation of this system will be described based on the flowcharts of FIGS. First, when an earthquake occurs, the seismometer 3 detects initial fine movement (S1). The seismometer 3 that has detected the initial tremor estimates the epicenter, the magnitude of the earthquake, and the arrival time of the main motion. Then, disaster prior information including such information is transmitted to the receiver 1. In addition, the time from the arrival of the main motion at the position of the seismometer 3 to the end is measured, and the duration information of the main motion is given to the receiver 1 after the end of the main motion at the position of the seismometer 3. Send.

  In the receiver 1, disaster advance information is received by the transmission / reception unit 10 (S2). In general, the P wave, which is the initial tremor of the earthquake, has a speed of 6 to 13 km / sec, whereas the S wave, which is the main motion of the earthquake, has a speed of 3.5 to 7.5 km / sec. If a P wave can be detected near the epicenter, a time of about 20 seconds can be secured from the reception of the disaster prior information to the arrival of the S wave at a point 100 km away from the epicenter. In this system, the following operations are performed during the time until the arrival of the S wave. Here, the control part 20 performs the operation | movement below S3 only when the earthquake of a predetermined magnitude or more generate | occur | produces.

  In addition, after the occurrence of a large earthquake, aftershocks may occur, so the control unit 20 performs the following operation. When the occurrence of an earthquake of a predetermined size or more is detected from the disaster prior information, the number of earthquakes stored in the earthquake history storage unit 13 is read out, and 1 is added to the number of earthquakes to be stored. When the number of read earthquakes is 1 or more, the control unit 20 determines that the earthquake is an aftershock, and resets the predetermined value of the earthquake scale for performing the following operation to a smaller value. Set. As a result, if it is an aftershock, the operation after S3 is performed even in a small-scale earthquake. In the case of an aftershock, the building may have already been damaged by the first earthquake, so even if the scale is smaller, the operation after S3 should be performed to minimize the damage caused by the aftershock. Can do.

  When the transmission / reception unit 10 receives the disaster prior information and it is larger than the set predetermined scale, the control unit 20 reads the alarm content from the alarm storage unit 11 (S3). First, the control unit 20 reads the basic alarm A from the alarm storage unit 11. Here, the control unit 20 determines the degree of urgency based on the earthquake arrival time information included in the disaster advance information. The degree of urgency is a numerical value corresponding to the time to reach the main motion at the place where the receiver is installed. In this embodiment, “1” is within 10 seconds until the main motion is reached, and “2” is 10 to 20 seconds. “3” for 20 to 30 seconds and “4” for 30 seconds or more.

  The control unit 20 refers to a table as shown in FIG. 3 stored in the alarm storage unit 11 and reads the content of the alarm before the earthquake corresponding to the degree of emergency specified by the disaster prior information. Here, when the urgency level is low, alarm contents corresponding to a higher urgency level are also read out. For example, when there is only 8 seconds until the main motion arrives, the urgency level is 1, so the alarms 1 and 6 corresponding to the urgency level information 1 are read. On the other hand, when there is 30 seconds or more until the main motion arrives, since the urgency is lower 4, all alarms 1 to 6 corresponding to urgency information of 4 or less are read. In addition, when the additional warning B is registered, the additional warning B is read from the warning storage unit 11 together. As the contents of the additional warning B, when the installation location of the receiver 1 is a tsunami danger area, a landslide disaster area, or a collapse dangerous house, there is a warning that warns in advance of the danger before the earthquake arrives. Note that the additional alarm B may be alarm contents regarding other risks.

  When the control unit 20 reads out the alarm content from the alarm storage unit 11, the control unit 20 sends the alarm content to the alarm generation unit 22 to issue an alarm before reaching the main motion (S4). The alarm generation unit 22 converts the alarm content received from the control unit 20 into an audio signal and generates audio from the speaker 22a.

  Before reaching the main movement, it is desirable to issue a female voice alert. In general, when an emergency occurs, it is said that female voices are less likely to panic the listener. In addition, when an elderly person is present at the place where the receiver 1 is installed, the alarm generation unit 22 can be set so as to issue an alarm that is slower than usual.

  Further, the control unit 20 causes the display control unit 23 to display the alarm content on the display unit 23a. By displaying the alarm in this way, for example, it is possible to notify the hearing-impaired person of the occurrence of the earthquake. Further, not only the display but also the occurrence of an earthquake may be notified by other means such as a flashlight or a vibration.

  Next, the control unit 20 causes the sensitivity switching unit 21 to increase the sensitivity of the sensor 5 (S5). That is, when the sensor 5 detects a fire, the fire occurrence is determined even at a lower temperature, and when the sensor 5 detects a gas leak, a lower gas is detected. A gas leak is also determined by detecting the concentration. For example, when the sensor 5 detects a fire, when a 65 ° C. signal is output from the heat sensor during normal operation, it is determined that a fire has occurred at 50 ° C. Change as follows.

  In the event of an earthquake, there is a high possibility of fire and gas leaks. Therefore, by increasing the sensitivity of the sensor 5 in advance before reaching the main motion, the actual fire or gas will be detected after the main motion is reached. Even if a leak occurs, it can be detected early and a quick response can be taken.

  Once the sensitivity of the sensor 5 is switched, the control unit 20 performs valve control (S6). The control unit 20 outputs a close signal from the valve control unit 24 to the open / close valve 6a of the gas pipe 6 to close the open / close valve 6a. Further, the control unit 20 switches the power supply (S7). Electric power is supplied to the receiver 1 from the external power line 4 to the external power supply unit 16, but the control unit 20 transmits a signal to the power supply switching unit 17 to switch the power source to the built-in battery 15 side. .

  With these operations, the supply of gas through the gas pipe 6 can be stopped to prepare for damage to the gas pipe 6, and the power source of the receiver 1 can be switched to the built-in battery 15 to prepare for a power failure. Since these operations can be performed before the main movement arrives, it is possible to prepare for the case where the building collapses or the receiver 1 is damaged due to the earthquake.

  Next, the control unit 20 stops power supply monitoring (S8). The power supply monitoring unit 25 always monitors whether the external power supply is supplied so that the external battery automatically switches from the external power supply to the built-in battery 15 at the time of a power failure and automatically switches from the internal battery 15 to the external power supply when the power is restored from the power failure doing. However, when an external power supply is restored again after an earthquake and a power failure, automatic switching to the external power supply may cause leakage or abnormal heating of the heater. Therefore, when receiving disaster prior information in which it is known that an earthquake will occur, the control unit 20 stops the power supply monitoring unit 25 so that the external power supply is not energized unless it is manually operated even if the external power supply is restored.

  It should be noted that the gas supply stop by the gas pipe 6 is also set so that it is not automatically recovered in the event of an earthquake when it is configured to automatically recover upon resumption of supply. Thus, it is possible to prevent secondary disasters associated with the restoration of the gas line.

  The operation of the control unit 20 at the time of receiving the disaster prior information is not necessarily performed in the order of FIGS. 4 and 5 and can be appropriately changed. Each operation may be performed in parallel.

  As described above, when the disaster prior information is received, a warning corresponding to that is issued, so that it can be prepared to some extent before the arrival of the main movement, and the sensitivity switching of the sensor 5 and valve control, By performing each operation of power supply switching and power supply monitoring stop, it is possible to reliably perform an operation for ensuring safety before reaching the main motion.

  For these operations, even if the disaster prior information is received, if the information on the magnitude of the earthquake included therein is below a predetermined value, the control unit 20 does not perform part or all of it. Also good. Thereby, it can prevent that various apparatuses stop frequently by a small-scale earthquake. In addition, the predetermined value of the earthquake scale can be set as appropriate depending on the presence or absence of the elderly, the age of the building, the presence or absence of the earthquake-resistant structure, and the like.

  Next, the operation when the main movement arrives will be described. When the main motion is detected by the seismic sensor 14 (S9), the control unit 20 reads the alarm content corresponding to the arrival of the main motion from the alarm storage unit 11 (S10). The alarm content at the time of arrival of the main motion is the basic alarm C as described above, and the control unit 20 combines the basic alarm C and the duration information of the main motion transmitted from the seismometer 3 after the disaster advance information. An alarm for notifying the alarm generation unit 22 of the duration of the main motion is issued (S11).

  In the event of an earthquake, it is usually unknown how long an earthquake will last, but this system alerts the duration of major movements by alerting the victim to anxiety even in situations where there is significant shaking. And can minimize the swaying of the victims after the shaking has subsided.

  Furthermore, the operation when the main movement is finished will be described. When the end of the main motion is detected by the seismic sensor 14 (S12), the control unit 20 reads the alarm content corresponding to the end of the main motion from the alarm storage unit 11 (S13). The alarm contents after the end of the main movement are the basic alarm D, the tsunami alarm E, the landslide alarm F, and the high-rise house alarm G as described above, and the basic alarm D is read in principle.

  Here, in reading out the alarm contents, the control unit 20 first reads out the geographical information from the geographical information storage unit 12 that stores beforehand the geographical information of the place where the receiver 1 is installed. The geographical information stored in the present embodiment is any one of a high-rise house facing a coast, adjacent to a mountain, and a control unit 20 giving an alarm corresponding to the information. Read from the alarm storage unit 11. The correspondence is registered in the control unit 20 in advance.

  If geographical information is not particularly registered in the geographical information storage unit 12, the control unit 20 reads the basic alarm D from the alarm storage unit 11, and if geographical information is registered, the corresponding alarm is stored as an alarm. Read from unit 11. When the alarm is read, the control unit 20 causes the alarm generation unit 22 to issue the read alarm (S14).

  In addition, it is desirable to use a male voice alert as a warning prompting evacuation at the end of the main movement. This is because male voices are more appropriate in situations where guidance is required, such as evacuation guidance. In addition, when an elderly person is present at the place where the receiver 1 is installed, the alarm generation unit 22 can be set so as to issue an alarm that is slower than usual. Further, as in the case of the alarm issue in S4, the control unit 20 may cause the display control unit 23 to display the alarm content on the display unit 23a.

  Further, when the receiver 1 is installed in each dwelling unit of the apartment house and the receiver 1 of each dwelling unit is connected to the dwelling unit receiver installed in the manager's room or the like, each receiver 1 The safety of the victim may be confirmed by an acoustic stop switch 26 provided in the vehicle.

  The acoustic stop switch 26 is for stopping an alarm by voice, and when the control unit 20 detects that the stop switch 26 is pressed, the control unit 20 stops the generation of the alarm and receives the residence building from the transmission / reception unit 10. A safety confirmation signal is transmitted to the machine. The dwelling receiver that has received the safety confirmation signal displays that fact for each dwelling unit and notifies the safety confirmation.

  Further, when the control unit 20 detects that the stop switch 26 has been pressed, a safety confirmation signal may be transmitted from the transmission / reception unit 10 to a mobile phone or the like registered in advance in the form of an email. Good. According to this, it is possible to notify the safety of the family who is out. In addition, you may make it provide a safety confirmation switch for exclusive use instead of using the sound stop switch 26 for safety confirmation.

  Although the embodiment of the present invention has been described above, the application of the present invention is not limited to this embodiment, and can be applied in various ways within the scope of its technical idea. For example, the geographical information and the content of the alarm corresponding thereto are not limited to the above embodiment, and various alarms according to the installation location of the receiver 1 can be issued.

  In addition, the geographical information storage unit 12 stores the fact that the area is a tsunami hazard area, earth and sand disaster area, or a collapse danger house, and the receiver 1 receives the disaster prior information, and the magnitude of the earthquake is greater than or equal to a predetermined value. In such a case, the control unit 20 may immediately read the alarm content of the outdoor evacuation guidance from the alarm storage unit 11 without determining the degree of urgency, and cause the alarm generation unit 22 and the display unit 23a to issue the alarm content. . This is because it is necessary to evacuate as soon as possible when there is a risk of a tsunami, landslide disaster, or collapse.

  Furthermore, if there are people who cannot evacuate on their own, such as elderly people or people with physical disabilities in the building, ensure safety by receiving disaster pre-information and making a support request immediately. Can do. Therefore, when the receiver 1 receives the disaster prior information and the magnitude of the earthquake is greater than or equal to a predetermined value, the control unit 20 sends a support request signal from the transmitting / receiving unit 10 to an external predetermined device without any operation.
