Description

  The present invention relates to a communication system that notifies a rescue worker or the like of a location of a disaster victim for the purpose of rescue / search for the disaster victim, for example, when a disaster occurs.

  When a disaster such as an earthquake that would cause a building to collapse occurs, the victim may be unable to escape on their own due to the underlayment of rubble. In such a situation, the survival rate decreases with time, so it is necessary to rescue victims who have been trapped as soon as possible. In addition, with the spread of mobile phones in recent years, victims who have been trapped may be locked together with mobile phones. In such a case, a conscious victim tries to use the mobile phone as a communication means for a rescue request.

  In this regard, Japanese Patent Application Laid-Open No. 2003-198751 describes a system in which a safety confirmation center transmits a mail confirming safety to a disaster victim at the time of a disaster, and the disaster victim confirms safety by replying to the mail. .

In addition, regarding the case where there is no awareness of the victim, Japanese Patent Laid-Open No. 2003-109160 discloses a mobile phone function of a mobile terminal that is automatically possessed when a sensor is attached to the body and the sensor senses an abnormality. And a system for requesting rescue using a short-range wireless function such as Bluetooth.

  FIG. 6 is a diagram showing the configuration of the rescue system according to the present embodiment. When a disaster occurs and rubble is generated due to the collapse of a building, etc., it is trapped under the rubble while holding the mobile phone 100 described above, and it becomes a state that requires searching / rescue, that is, a rescuer is required. There are victims.

  In such a situation, when the rescuer is conscious and the mobile phone 100 can be operated, the rescuer switches the mobile phone 100 to the rescue mode. The mobile phone 100 that has been switched to the rescue mode notifies that the switching has been performed, for example, as illustrated in FIG.

  When the disaster countermeasure organization recognizes that a disaster has occurred, the above-described relay sensor 200, position information providing sensor 300, and information storage sensor 400 are dispersed from the air using an aircraft such as a helicopter. By concentrating and spreading these sensors around the rubble, a plurality of sensors are made to exist in a range in which communication is possible directly from the mobile phone 100 possessed by the rescuer. As means for recognizing that a disaster has occurred, information from a device that detects the occurrence of a disaster, such as a seismometer, or information from a disaster-stricken area is used alone or in combination. As a method of spraying the sensor, in addition to spraying from an aircraft, a vehicle may enter and spray the disaster area, or a rescue member may spray manually.

  Next, the operation of the mobile phone 100 that has been switched to the rescue mode will be described. In order to transmit the rescue signal, the rescue mode processing function unit 104 of the mobile phone 100 that has been switched to the rescue mode first uses the ad hoc network function unit 103 in step S101 of FIG. And broadcast packets to search for sensors. The packet has the structure shown in FIG. 9, and the source address is set to its own address that can be generated based on the unique ID assigned to the mobile phone 100 itself or the wireless LAN interface 101, and the destination address is set to the destination address. A special address indicating broadcast is set, the current time acquired from the clock 111 is set as time information, and special data indicating that no position information exists, for example, 999; Is set with data indicating that a neighboring node is searched.

In S102, it is confirmed whether there is a response from a nearby mobile phone or sensor.
If there is no response from anywhere, the process waits for time T11 in S103 and repeats the search for neighboring nodes in S101. The value of T11 is set to an appropriate value according to the remaining amount of the battery 113. For example, the apparatus waits for 5 seconds at first, and each time the standby is repeated, the waiting time is doubled, such as 10 seconds or 20 seconds. If the waiting time becomes 1 hour or longer, the standby time is not increased and is fixed to 1 hour. The response message from the nearby mobile phone or sensor includes position information and time information indicating the location of the nearby mobile phone or sensor.

  If there is a response from a nearby mobile phone or sensor, the GPS information is acquired using the GPS receiver 102 in S104. When the GPS information cannot be acquired because the radio wave from the GPS satellite could not be received, the result that the GPS information could not be acquired is stored in the memory 112.

  In S105, the GPS information acquired by the GPS receiver 102 using the location information measurement function unit 105, or time information and location information included in a response message from a nearby mobile phone or sensor, Location information is measured using information such as the time when a response message from a telephone or a sensor is received. Further, as a result of the position measurement, for example, when it is found that the time indicated by the clock 111 is shifted due to the time information acquired by the GPS receiver 102 being different from the time indicated by the clock 111, for example, The time of the clock 111 is corrected. Even when GPS information from GPS satellites cannot be received, the location of the mobile phone can be measured by the same method as GPS positioning using the location information and time information acquired from the surrounding mobile phones and sensors. it can. In this case, although the positioning accuracy is lower than that of GPS positioning, in this embodiment, it is sufficient if the approximate location of the mobile phone is known.

  In S106, first, information from the vital sensor worn by the rescuer is processed by using the vital sensor information processing function unit 110, and a rescue signal is generated together with the time information and the position information measured in the above steps. Send by communication. Set your own address as the source address, set a special address indicating the recipient of the rescue signal as the destination address, and set the time information and location information measured in the above steps as the time information and location information In the data, the information acquired from the vital sensor is set together with the data indicating the rescue signal. Pulse rate, blood pressure, etc. can be used as information that can be acquired from the vital sensor.

  In S107, a response message indicating that the rescue signal has been received is received.

In S108, it is confirmed whether or not the signal could be received in the step.
If it can be received, the process waits for time T12 in S109 and repeats from S106.

  If it could not be received, it waits for time T13 in S110 and repeats from S106. The value of T12 is set to 1 hour, for example, in order to make the battery 113 last longer. The value of T13 is doubled until the initial value is set to 1 minute, for example, and reaches 10 minutes.

  Next, the operation of the spread relay sensor 200 will be described. In order to know the position of the relay sensor 200 and construct an ad hoc network, the relay sensor 200 first broadcasts a packet for searching for neighboring sensors and mobile phones in S201 of FIG. 10 immediately after being distributed. The source address is set to the own address that can be generated based on the unique ID assigned to the relay sensor 200 itself or the wireless LAN interface 201, the destination address is set to a special address indicating broadcast, and the time information Is set with the current time acquired from the clock 204, the position information is set with special data indicating that the position information does not exist, for example, 999; 999, and the data includes data indicating that a neighboring node is searched for. Set. Immediately after the relay sensor is sprayed, the time is not set in the clock 204, and therefore an incorrect value may be set as the current time. In S202, it is confirmed whether there is a response from a nearby sensor or mobile phone.

  If there is no response from anywhere, the process waits for time T21 in S203 and repeats the neighboring node search in S201. For example, the value of T21 is initially set to 5 seconds, and the standby time is doubled, such as 10 seconds and 20 seconds, each time the standby is repeated. Since the sensors are dispersed so that other sensors exist in the vicinity, the upper limit of the waiting time is 5 minutes. The response message from the nearby mobile phone or sensor includes position information and time information indicating the location of the nearby mobile phone or sensor.

  In S204, position information is measured using information such as time information and position information included in a response message from a neighboring sensor or the like, and information such as a time when a response message from a neighboring sensor or the like is received. As described above, the position of the relay sensor can be measured by the same method as the GPS positioning using the position information and time information acquired from the surrounding mobile phones and sensors. In this case, although the positioning accuracy is lower than that of GPS positioning, in this embodiment, it is sufficient if the approximate location of the relay sensor is known.

  If the received time information is more reliable than the time indicated by the clock 204, the time of the clock 204 is corrected.

  Next, the operation of the dispersed position information providing sensor 300 will be described. In order to provide position information to other sensors and mobile phones, the position information providing sensor 300 first uses the GPS receiving unit 307 built in S301 in FIG. The current time is acquired and the time of the clock 304 is corrected.

  Thereafter, in the same manner as the relay sensor 200, a packet for searching for nearby sensors and mobile phones is broadcast in S302.

In S303, it is confirmed whether there is a response from a nearby sensor or mobile phone.
If there is no response from anywhere, the process waits for time T31 in S304 and repeats the search for neighboring nodes in S302. For example, the value of T31 is initially set to 5 seconds, and the standby time is doubled, such as 10 seconds and 20 seconds, each time the standby is repeated. Since the sensors are dispersed so that other sensors exist in the vicinity, the upper limit of the waiting time is 5 minutes.

  In S305, using location information acquired by the GPS receiver 307, time information and location information included in a response message from a nearby sensor, information such as a time when a response message from a nearby sensor was received, etc. Measure location information. Only GPS positioning may be used, or GPS positioning and positioning based on time information and position information from nearby sensors may be used in combination. Further, as a result of the position measurement, when a time more accurate than the time indicated by the clock 304 can be acquired, the time of the clock 304 is corrected.

  Next, the operation of the dispersed information storage sensor 400 will be described. The operation from immediately after the information storage sensor 400 is dispersed until the ad hoc network is constructed is the same as that of the relay sensor 200.

  Next, the operation of the relay sensor 200 when the rescue signal transmitted from the mobile phone 100 is directly received will be described. First, a rescue signal is received in S401 of FIG. The determination that the received message is a rescue signal is made by confirming that a special address indicating the recipient of the rescue signal is set in the destination address.

  The relay sensor 200 has a routing table as shown in FIG. In S402, it is confirmed whether or not a special address indicating the recipient of the rescue signal is stored in the destination column in the routing table.

  If it is not stored, the route information to the receiving destination of the rescue signal is searched in S403. As a method for searching for route information, for example, a route information request message is broadcast to neighboring sensors, and the neighboring sensor responds if it knows the route information to the receiving destination, and if it does not know, it sends a route information request message. Forward. If the route information is successfully searched, the information is added to the routing table.

  If the search for the route information is successful or if the route information is already stored, a rescue signal is transferred to the next node according to the route information in S404.

  The operation of the position information providing sensor 300 when the rescue signal transmitted from the mobile phone 100 is directly received is the same as that of the relay sensor 200.

  Next, the operation of the information storage sensor 400 when the rescue signal transmitted from the mobile phone 100 is directly received will be described. The information storage sensor 400 is for receiving a rescue signal instead of the rescue crew carrying terminal 500 and transferring the rescue signal in response to a request from the rescue crew carrying terminal 500. When the rescue signal is received, The rescue signal is stored in the memory 405. Further, a response message indicating that the emergency signal has been received is transmitted to the mobile phone 100 that has transmitted the rescue signal.

  Next, the operation of the relay sensor 200 when a rescue signal transmitted from the mobile phone 100 is relayed from another sensor will be described. When the rescue signal is relayed from another sensor, the route search is performed by the sensor that has received the rescue signal directly from the mobile phone 100. Therefore, the route information to the destination is registered in the routing table. Therefore, there is no need to search for route information, and a rescue signal is transferred to the next node according to the information in the routing table stored in the memory 205.

  The operation of the position information providing sensor 300 when the rescue signal is relayed from another sensor is the same as that of the relay sensor 200.

  Next, the operation of the information storage sensor 400 when a rescue signal transmitted from the mobile phone 100 is relayed from another sensor will be described. Since the information storage sensor 400 is for receiving a rescue signal instead of the rescue crew carrying terminal 500 and transferring the rescue signal in response to a request from the rescue crew carrying terminal 500, the rescue signal is directly received from the mobile phone 100. The rescue signal is stored in the memory 405 in the same manner as when it is received. Further, a response message indicating that the emergency signal has been received is transmitted to the mobile phone 100 that has transmitted the rescue signal.

  Next, the operation of the rescue crew carrying terminal 500 when the rescue crew carries the rescue crew carrying terminal 500 and searches for a rescuer is described. When the rescue crew carrying terminal 500 approaches a distance that allows direct communication with the sensor, the rescue crew carrying terminal 500 starts searching for a nearby mobile phone or sensor. When a nearby mobile phone or sensor is found, the location of the found mobile phone or sensor is stored in the memory 509. When the information storage sensor 400 is found on the ad hoc network, the transmission of the stored rescue signal is requested. When a rescue signal from the mobile phone 100 or a rescue signal stored by the information storage sensor 400 is received through the ad hoc network, a response message is transmitted and the location of the mobile phone 100 is set to the rescue crew carrying terminal 500. It is displayed on the display and shown by coloring the emergency level candidate of the rescuer based on the vital sensor information. For example, if the pulse or blood pressure shows normal values, it will blink green, if the pulse or blood pressure is reduced, it will blink yellow, and if the pulse or blood pressure is significantly reduced, it will turn red. Blinks in black when the pulse or blood pressure cannot be read. For example, a screen as shown in FIG. 14 is displayed on the display of the rescue crew carrying terminal 500. In FIG. 14, each circle indicates the location of the mobile phone (rescued person) displayed based on the position information included in the rescue signal. Further, the physical condition of the rescuer is shown in correspondence with the location of the mobile phone (rescue person).
