Description

  The present invention relates to an exploration support system and a transmission device and a central processing device used in the system, and more particularly to a search support system, a transmission device, and a central processing device that improve the work efficiency of large-scale rescue activities and investigation activities.

The tsunami generated by the Tohoku-Pacific Ocean Earthquake destroyed a vast area devastatingly. While many precious lives were lost, many were saved by the great efforts of the SDF, police, fire department, and other local people.

Since Japan is a country that is hit by many disasters such as typhoons, earthquakes, and tsunamis, various systems have been developed to combat them.

For example, Patent Document 1 discloses a rescue activity support system that can automatically dispatch a rescue team or the like to a disaster-stricken place in a short time during a disaster. In this system, the location information of the victim is transmitted to the emergency center, so that the rescue operation by the rescue team can be speeded up.

JP 2006-127111 A

In general, the probability of survival in the event of a disaster is assumed to drop sharply after 72 hours from the disaster. On March 11, 2011, when the Great East Japan Earthquake occurred, the temperature was still low, and in the Tohoku region, the remaining winter was extremely severe, so the actual time between life and death was between 24 and 48 hours. It is thought that it was. It seems that many of the victims who were involved in the tsunami and who were wet with seawater were exhausted while waiting for rescue under the rubble.

Therefore, in the event of a disaster, the quick start of rescue operations is most important to save as many lives as possible. In the recent earthquake disaster, 20,000 Self-Defense Forces were introduced for rescue operations at an early stage, and in this regard, the government's response is considered to be able to be evaluated to a certain extent.

However, if a major disaster occurs, the number of members to be introduced increases, and the disaster-stricken area becomes enormous, the rescue operation will be rough. That is, a blind spot in which rescue operations are not performed partially occurs for the following reasons.

In general rescue activities, XX town △△ addresses can be assigned as rescue team members A to D, but when the scale of the disaster exceeds a certain level like this time, there is no longer any landmark. , It becomes difficult to know exactly which member has already completed which exploration activity.

Therefore, in a large-scale disaster such as this time, another member is informed whether or not the exploration activity has already been done by setting a flag at the place where exploration activity has been completed or marking with a spray. This prevents the search efficiency from decreasing.

However, flags and sprays are limited, and the exact search completion position cannot be indicated in this way. People who are under a collapsed building are often unable to speak, and even if rescue workers pass through a distance of only 10 meters away, they will not be aware of their existence and will be judged to have already been searched. Can also happen. If that happens, it's already hopeless. It is unlikely that a rescue operation will begin again within 72 hours.

In this way, in the event of a major disaster, the rescue operation was rough, and even though the rescue hand was imminent to the next step, it was overwhelmed by fate and the situation of losing life occurred .

Moreover, although the rescue operation support system of Patent Document 1 can improve the efficiency of rescue operations for small-scale disasters, it can no longer perform its function for large-scale disasters that inevitably require human naval tactics. I couldn't.

In view of the above-mentioned problems, the present invention is used in a rescue / investigation support system capable of improving search efficiency in a large-scale search activity based on human naval tactics, a transmission device used in the system, and a transmission device An object is to provide a display method.

An exploration support system according to the present invention includes: a transmission device including a detection unit that detects a current position; a transmission unit that transmits position information regarding the detected current position at a predetermined frequency; and a plurality of the transmission devices. A central processing unit including a generation unit that identifies a position where a rescue operation or an investigation activity has been performed based on the transmitted position information and generates rescue / survey activity completion area information.

Further, the transmission device of the present invention indicates a detection means for detecting the current position, a transmission means for transmitting position information relating to the detected current position at a predetermined frequency, and a position where the rescue operation or the investigation activity has been performed. Receiving means for receiving rescue / survey activity completion area information, storage means for storing map information, and a map around the current position detected by the detection means based on rescue / survey activity completion area information. Display means for displaying the position where the activity is performed and the position where the activity is not performed in a distinguishable state.

According to the present invention, it is possible to improve search efficiency in a large-scale search activity based on human naval tactics.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(Embodiment 1)
FIG. 1 is a block diagram of a search support system according to Embodiment 1 of the present invention. The search support system 1000 includes a plurality of transmission devices 100 and a central processing device 200.

Here, the search support system 1000 is a system that is particularly used for a rescue operation after a disaster or an investigation activity such as terrorism or crime, and becomes a rescue support system or an investigation support system depending on how it is used. Hereinafter, the search support system may be referred to as a rescue / survey support system in some cases.

  The transmission device 100 is a device possessed by each of a plurality of members performing search activities, and includes a position detection unit 110 and a transmission unit 120.

  The position detection unit 110 is a detection unit that detects the current position of the apparatus, and obtains the current position by, for example, a position detection method using GPS. Specifically, satellite-specific C / A code signals transmitted from a plurality of satellites are received via a GPS antenna, and a pseudo distance to each satellite is calculated based on the timing of the signal received from each satellite. Find the current position and time. In addition, the position detection unit 110 includes an acceleration sensor that detects acceleration, an orientation sensor that detects an orientation, and the like as necessary, and information such as acceleration, orientation, and other angular velocities obtained by these sensors is included in the GPS. A more accurate position can be obtained in combination with the position obtained in (1).

The transmission unit 120 transmits information related to the current position detected by the position detection unit 110. The transmission method can wirelessly transmit to a base station (not shown) using a mobile communication network. However, the specific configuration of the transmission unit 120 is not limited to this. If a large-scale disaster occurs, the mobile communication network may be down, and even if a communication module corresponding to an existing mobile communication system such as WCDMA or LTE is installed as the transmission unit 120, communication can be performed appropriately. There is no possibility. Therefore, the transmission apparatus 100 may be equipped with a transmission module corresponding to a transmission method using a frequency band separately allocated for disaster as the transmission unit 120. Further, a communication module that can be connected by a plurality of communication methods may be mounted. Here, it is assumed that the transmission unit 120 is configured to transmit information regarding the current position by communicating with a base station using a mobile communication network.

  The central processing unit 200 is a central computer arranged in the search support center, and includes a communication unit 210 and a search activity completion area information generation unit 220.

  The search support center is a center for supporting search activities such as rescue activities, and multiple staffs centrally grasp the disaster situation based on information sent from each transmitter and give appropriate instructions .

  The communication unit 210 of the central processing unit 200 receives position information regarding the current position of each transmission device 100 transmitted from the plurality of transmission devices 100 via the base station and the mobile communication network. The position information received by the communication unit 210 is output to the search activity completion area information generation unit 220.

The search activity completion area information generation unit 220 of the central processing unit 200 identifies a position where the search activity has been performed based on the position information transmitted at a predetermined frequency from the plurality of transmission devices, and collects the information. To generate search activity completion area information.

Here, the search activity completion area information is information indicating a position range where the search activity has already been performed by the members who are performing the search activity, and the position information transmitted from the plurality of transmission devices 100 is collected. . That is, the position indicated by the position information transmitted from each transmission device 100 indicates that the members were at the position, and it can be recognized that the search activity has already been performed for the position.

Here, the search activity completion area information is rescue activity completion area information if the search activity content is specifically a rescue activity, and is search activity completion area information if the search activity is an investigation activity. In the following description, the search activity completion area information is sometimes referred to as rescue / survey activity completion area information.

  According to the above search support system, when a plurality of search members search by human naval tactics, position information regarding the position where the search activity is completed is transmitted from each search member to the search support center. By integrating these, the position where the search activity is completed can be grasped as a whole. Therefore, the search support center can confirm the search situation of the situation on the spot in real time, and point out the search point by pinpointing the position where the search leak is occurring, Can prevent and improve efficiency.

That is, according to the search support system of the present invention, it is possible to perform far more detailed search activities compared to the conventional search method performed after a disaster. This is due to the following reason.

  A major cause of coarseness in the conventional search methods is low information gathering ability. In missions such as general rescue and investigation, it is necessary to unify the command system and to give detailed instructions to each unit as the number of members to be introduced increases and the search scale increases. In conventional exploration activities after a disaster occurs, members are introduced to the scene after the placement status of each member is determined by briefing prior to the introduction of the members.

However, as the search activity progresses, the situation changes from moment to moment, and members take actions that deviate from the originally planned action plan. Normally, it is inevitable that a member who takes action on the spot will respond to the situation depending on the situation, so that the center of the command system collects current information as appropriate and collects necessary additional instructions and The strategy needs to be corrected. In conventional exploration activities, the information gathering function has not been demonstrated, and the center has not been able to properly grasp the situation at the site.

One of the reasons why this information gathering function could not be demonstrated is that in the rescue operation after a major disaster, the communication system is weakened due to the destruction of the radio communication network and traffic infrastructure due to the disaster. . In addition, after a disaster occurs, calls for confirming the safety of the general public also suddenly swell, so even in a mobile communication network having a relatively large band compared to other wireless communication systems, Punctures. For these reasons, it is necessary to use general conversations to give command from the center to the site and feedback from the site to the center in view of the fact that many members are being put together in a dense area. Is also very difficult.

In view of such a situation peculiar to a catastrophe, in the present invention, the central processing unit arranged in the center sucks up the position information of each member from the transmission device owned by each member, and based on these information, The behavior is grasped, and the position range where the search activity is performed as a whole is obtained. Therefore, the information transmitted from each transmitting device to the central processing unit requires a very small amount of information, and the center can collect the most necessary information without squeezing radio resources. And since it is possible to grasp the situation at the forefront site from such information, it becomes possible to correct the strategy and notify the necessary command.

(Embodiment 2)
In the search support system 2000 according to the second embodiment, in addition to the configuration of the search support system 1000, the search support center transmits search activity completion area information to each transmission device, and each member on the site appropriately determines based on their own judgment. It is an improved system that can take various actions.

  FIG. 2 is a diagram showing a configuration of transmitting apparatus 300 used in the second embodiment. The transmission apparatus 300 includes a position detection unit 310, a communication unit 320, a storage unit 330, an input unit 340, a central control unit 350, and a display unit 360. Each part is connected to each other through a bus.

Similar to the position detection unit 110, the position detection unit 310 detects the current position of the apparatus by a position detection method using GPS or the like. Specifically, the pseudo position to each satellite is calculated based on the satellite specific C / A code signals transmitted from a plurality of satellites to obtain the current position and time. In addition, the position detection unit 310 includes an acceleration sensor that detects acceleration, an orientation sensor that detects an orientation, and the like as needed. By interpolating the current position at each time obtained by the GPS using information such as acceleration, direction, and other angular velocities obtained by these sensors, the position detection frequency is compared with the position detection method using only GPS. Can be raised.

The communication unit 320 transmits information related to the current position detected by the position detection unit 310. Further, the communication unit 320 receives the search activity completion area information generated by the central processing unit 200. The received search activity completion area information is stored in the storage unit 330 according to the control of the central control unit 350.

The storage unit 330 stores / updates the search activity completion area information received by the communication unit 320. FIG. 3 shows an example of search activity completion area information. As shown in FIG. 3, the search activity completion area information includes information on the position where the search is completed. The storage unit 330 stores other map information. As the map information, commercially available data such as Naviken S standard-compliant map data can be used as it is. The header portion of the search activity completion area information includes management information such as version information of the search activity completion area information, transmission date and time, and transmission target group.

The input unit 340 is an input unit that receives an input from the user, and can specifically take the form of a touch key or a touch panel. The user instructs the central control unit 350 via the input unit 340 to change the setting of the enlargement ratio of the map displayed on the display unit 360 or to specify the position range of the map to be displayed.

  The central control unit 350 controls the entire transmission device 300. Further, the central control unit 350 reads the map information and the search activity completion area information stored in the storage unit 330 and outputs them to the display control unit 360. More specifically, the central control unit 340 includes the position range near the current position detected by the position detection unit 310 and the input unit 340 among the map information and the search activity completion area information stored in the storage unit 330. A portion corresponding to the position range near the position instructed by the user is read and temporarily stored in the buffer in the display unit 360.

  The display unit 360 draws and displays a map. At this time, the display unit 360 displays the map in a state where the position where the search activity is performed and the position where the search activity is not performed can be discriminated based on the search activity completion area information.

Specifically, the display unit 360 includes a display control unit and a display panel. The display control unit reads the map information temporarily stored in the buffer under the control of the central control unit 350 and draws the map. Further, the display control unit reads the search activity completion area information, draws a predetermined icon at a location where the search indicated by the search activity completion area information is completed, and displays the overlay on the map. The display unit 360 also displays an overlay on the current position portion detected by the position detection unit in the map together with an icon indicating the current position.

  FIG. 4 shows an example of a display screen displayed on the display panel of the display unit 360. The display panel includes an icon (☆) indicating the current position, and an icon (diagonal line icon) indicating the position range where the search has been completed. ) Overlaid on the map. Here, as shown in FIG. 4, in the area indicated by the map, although the search activity is completed as a whole, a part of the search indicated by B or the area indicated by C is partially omitted. On the other hand, each user can easily confirm that a search omission has occurred by looking at the display screen displayed on the display panel. Can be eliminated. Also, you can easily check where you and other members have already conducted exploration activities, so you can avoid the trouble of checking the same location many times.

  The search activity completion area information transmitted from the central processing unit may be configured such that only the difference from the previously transmitted search activity completion area information is transmitted. May include information on all position ranges for which the search activity has been completed. In any case, the search activity completion area information has a version of the information in the header portion. By storing and updating the search activity completion area information in the storage unit for the area where the search activity that increases with the passage of time is completed, a member having each transmission device can appropriately grasp the latest situation.

(Embodiment 3)
The transmission apparatus according to Embodiment 3 further includes a generation unit that generates individual search activity completion area information by collecting information on the current position detected by the position detection unit for a certain period. Here, the individual search activity completion area information is information indicating a position range where the owner of each transmission device has completed the search activity. The central processing unit 200 collects the individual search activity completion area information transmitted from a plurality of transmission devices and generates search activity completion area information.

  FIG. 5 is a diagram showing a configuration of transmitting apparatus 400 according to the third embodiment. The transmission device 400 includes an individual search activity completion area information generation unit 470 in addition to the position detection unit 310, the communication unit 320, the storage unit 330, the input unit 340, the central control unit 350, and the display unit 360. Prepare. Hereinafter, the configuration of the transmission apparatus 400 will be described in detail. However, a part of the description of the blocks described in the transmitting apparatus 300 is omitted.

  The position detector 310 detects the current position and the current time at the first frequency. Normally, the detection frequency in the position detection unit 310 is detected every about 0.1 seconds to 10 seconds, but is not limited thereto. The detection frequency may be configured to be lowered depending on the battery level of the device itself. Information on the detected current position and current time is output to the individual search activity completion area information generation unit 470.

The individual search activity completion area information generation unit 470 generates individual search activity completion area information indicating an area where the individual search activity is completed. Specifically, the individual search activity completion area information is generated by collecting the current position and the current time detected at the first frequency in the position detection unit 310 for a certain period, and the generated individual search activity completion area information is used as the central control unit. The data is output to the communication unit 320 according to the control 350. Here, the individual search activity completion area information generation unit 470 generates the individual search activity completion area information by collecting the plurality of current positions and current times detected by the position detection unit 310 in a period of about 10 seconds to 10 minutes. To do.

FIG. 6 shows an example of the individual search activity completion area information. As shown in the figure, the positions detected by the position detection unit during a predetermined period are collected in association with the detection time.

The individual search activity completion area information generated by the individual search activity completion area information generation unit 470 is transmitted from the communication unit 320. Here, the individual search activity completion area information generation unit 470 generates individual search activity completion area information for each period of about 10 seconds to 10 minutes, so the communication frequency in the communication unit 320 is also about 10 seconds to 10 minutes. Sent once.

According to the above transmission apparatus, the current position is detected with a fine frequency, and the individual search activity completion area information in which the current position is collected for a certain period is transmitted with a frequency less than the detection frequency. Thus, since the current position obtained by the position detection unit is information used for specifying the searched place, it is necessary to obtain it with high accuracy and relatively accurately. On the other hand, when transmitting information on the current position to the central processing unit, real-time performance is not so required. Therefore, the information on the current position detected by the transmitting device for a certain period of time as in the transmitting device of the present embodiment is held, and after collecting this information as individual search activity completion area information, the burst is performed at a frequency less than the detection frequency. It is desirable to transmit because of the communication band. This is because a large number of members enter a certain area and perform search activities for searching, so if each transmitting device frequently establishes a connection with the base station and transmits / receives information on the current position, the communication capacity is not in time. there is a possibility. For this reason, the information on the current position from the transmitting device that does not require real-time performance to the central processing unit is clarified from the correspondence relationship between the position and the detection time, and then transmitted after being collected for a certain period. Can be used effectively.

It is even better if the individual search activity completion area information generation unit 470 generates individual search activity completion area information including a unique identifier that identifies the own transmission device 400 or a unique identifier that identifies the user of the transmission device 400. is there. Since the central processing unit can identify from which transmitting device the individual search activity completion area information sent from each of the plurality of transmission devices is sent, the management when generating the search activity completion area information collectively. Becomes easier. In addition, if a victim is found from a place where the exploration activity is supposed to be completed at a later date, it is possible to identify which member was responsible for that location, so why should the victim be identified while the exploration activity is being conducted? It will be possible to utilize the analysis and reflection of whether it was not found in future search activities. As such an identifier, a terminal manufacturing number, UIM manufacturing number, subscriber ID, terminal serial number, or the like can be used.

(Embodiment 4)
The transmission apparatus according to the fourth embodiment further includes a configuration for a member (a user of the transmission apparatus) performing a search to specifically identify the position where the search is completed and notify the central processing unit. To do. Hereinafter, the transmission apparatus according to the fourth embodiment will be described.

  FIG. 7 is a diagram showing a configuration of transmitting apparatus 500 according to the fourth embodiment. The transmission device 500 includes a position detection unit 310, a communication unit 320, a storage unit 330, an input unit 540, a central control unit 350, a display unit 360, and an individual search activity completion area information generation unit 570. . Hereinafter, the configuration of transmitting apparatus 500 will be described in detail. However, a part of the description of the blocks described in the transmitting apparatus 300 is omitted.

The position detection unit 310 detects the current position of the apparatus by a position detection method using GPS or the like. Information on the detected current position is transmitted from the communication unit 320 to the central processing unit as information indicating the current position of the member. Here, the information on the current position to be transmitted includes the coordinates of the detected current position, the detection time, an identifier unique to the transmission device 500, or a unique identifier that identifies the user of the device. The transmission frequency of the information on the current position is preferably, for example, between 1 second and 5 minutes, from the viewpoint of securing radio resources and grasping the appropriate crew member position. More preferably, it is between 10 seconds and 1 minute. The central processing unit can accurately grasp the arrangement status of each member based on the information on the current position transmitted from each transmission device.

  FIG. 8 shows an example of information regarding the current position transmitted from the position detection unit 310. As shown in the figure, the information transmitted from the transmission device 500 to the central processing unit is in a state in which the coordinates of the current position detected by the position detection unit, the detection time, and the identifier for identifying the transmission device 500 are associated with each other. included.

The storage unit 330 stores map information. Specifically, it can take the form of a built-in hard disk or flash memory.

The input unit 540 is an input unit that receives input from the user, and here is a touch panel specifically attached to the display unit 360. As will be described later, a member who is a user designates a position range in which the search activity is completed using the touch panel in the map displayed on the display unit 360.

  The display unit 360 reads the map information stored in the storage unit 330 and draws and displays the map. At this time, the display unit 360 reads the map information around the current position detected by the position detection unit 310 and displays the map information at an enlargement magnification instructed by the user via the input unit 540.

The individual search activity completion area information generation unit 570 generates individual search activity completion area information assuming that the position range designated by the user using the touch panel as an input unit is an area where the search activity has been completed. That is, a member who performs a search activity is an input unit for a position range in which a search activity is completed in the map around the current position displayed on the display unit of the transmission device 500 when the search activity in a certain position range is completed. Specify using the touch panel. The individual search activity completion area information generation unit 570 generates individual search activity completion area information by regarding the designated position range as an area where the search activity has been completed. The search activity completion area information generated by the individual search activity completion area information generation unit 570 is transmitted from the communication unit 320 to the central processing unit.

  As described above, in the transmission device according to the fourth embodiment, the member himself / herself generates the individual search activity completion area information by designating the position where the search activity is completed using the input means provided in the transmission device. With this configuration, although part of the labor for the members to input through the input means occurs, the individual search activity completion area information more accurately indicates the position range where the search activity has been completed. It is possible to appropriately grasp the position range where the search activity is completed and the position range where the search activity is not.

The individual search activity completion area information generation unit 570 completes the search activity by combining the position range specified based on the current position detected by the position detection unit 310, as in the transmission device 400 of the third embodiment. It may be included in the individual search activity completion area information as part of the position range. In this case, it is distinguished using an identifier or the like whether the information included in the individual search activity completion area information is information generated based on the current position or information generated based on an input instruction from the user. It is even better if the individual search activity completion area information is generated in a possible state. The central processing unit identifies which method is the individual search activity completion area information generated by the above-described method from the identifier included in the transmitted individual search activity completion area information, and relates to the area where the search activity is completed. Likelihood (reliability) may be provided.

(Embodiment 5)
The search support system according to the fifth embodiment is characterized in that the search activity completion area information transmitted from the central processing unit further includes information indicating the completion status of the search activity. Note that the configuration of the transmission apparatus is the same as the configuration of each of the above-described embodiments or a combination thereof, and thus the description of the specific configuration is omitted.

  The central processing unit according to the fifth embodiment generates search activity completion area information based on information on the current position transmitted from each transmission device or individual search activity completion area information. Here, in the search activity completion area information generated by the central processing unit, a position range in which the search activity is completed and information indicating the degree of completion (completion degree information) are associated and collected. Here, the information indicating the degree of completion can be said to be information indicating the reliability of the search activity performed.

FIG. 9 shows an example of the search activity completion area information. As shown in FIG. 9, the search activity completion area information summarizes a plurality of position ranges in a state in which the position range where the search activity is completed and the completion degree information of the position range are associated with each other. Here, the degree of completion information is expressed in 8 stages of 0 to 7, where 0 indicates that the search is such that a member has passed the position, and 7 is a reliable search using a search dog or the like. It is shown that.

In the transmission device, the search activity completion area information received by the communication unit is stored / updated in the storage unit. The search activity completion area information stored in the storage unit is read to the display unit according to the control of the central control unit, and the display unit is in a state in which the position where the search activity is performed and the position where the search activity is not performed can be discriminated. Draw and display a map.

Specifically, the display unit reads the map information stored in the storage unit according to the control of the central control unit and draws the map. Here, the display unit reads the search activity completion area information, draws a predetermined icon at a location where the search indicated by the search activity completion area information is completed, and displays the overlay on the map. At this time, the display unit draws a different icon based on the completion degree information included in the search activity completion area information and displays the icon overlaid on the map.

More specifically, the display unit stores eight different icons corresponding to each of the completion degrees 0 to 7 in a storage means such as a ROM held therein. The display unit draws a map of a predetermined area based on the read map information, and searches whether the position range included in the drawn map area is not included in the search activity completion area information. As a result of the search, when the position range is included in the search activity completion area information, the display unit refers to the completion degree information corresponding to the position range, reads the corresponding icon from the ROM or the like, and displays it on the map. Overlay display in the position range. In other words, the display unit displays the map in a state in which the degree of completion of the search activity can be determined for the position range where the search activity has been completed.

FIG. 10 shows an example of a map displayed on the display unit. The map is displayed in a state in which the completion degree of the search activity can be determined by displaying an icon corresponding to the degree of completion for the position where the search activity is completed. Here, different icons corresponding to the degree of completion are displayed in an overlay on the map in four stages of 1 to 4.

Here, as the icon corresponding to the degree of completion, as shown in FIG. 10, in addition to the method of representing the degree of completion by the shade of color, the use of icons having different colors, different hatching patterns, and the like, the degree of completion of the search activity can be improved. It may be in a state where it can be discriminated.

The individual search activity completion area information generation unit generates individual search activity completion area information including an identifier unique to the transmission device or an identifier unique to a member who is a user. In addition, when the transmission device is attached to the search dog, it is generated including an identifier unique to the search dog. The reason for including this identifier is that there is a difference in search ability between veteran members and new recruits, and the reliability (completion degree) for the search is different even if the same time search is performed. Further, since the search ability of the search dog is different from that of humans, an identifier is included so that the search can be specified as a search performed by the search dog. The generated individual search activity completion area information is transmitted from the communication unit to the central processing unit.

The central processing unit generates search activity completion area information including the degree of completion based on information on the current position transmitted from each transmission device and individual search activity completion area information. Here, the central processing unit obtains the degree of completion of the search at the position according to the length of time spent at the predetermined position specified from the information on the current position.

For example, if there is only a few seconds in the vicinity of a certain position, it is considered that only a verbal search activity is performed, so a low value is set as the degree of completion corresponding to that position. On the other hand, in the information on the current position, if the same position is detected as the current position for a relatively long time (several minutes or more) with respect to the predetermined position, it is considered that a focused search activity has been performed at the position. Therefore, a high value is set for the degree of completion corresponding to the position. Further, based on the information on the current position or the identifier included in the individual search activity completion area information, the degree of completion of the search for the position indicated by the information is obtained. For example, the central processing unit has a relatively high degree of completion even if the search time is short for the individual search activity completion area information including an identifier indicating an experienced member or a member searching using a special search device. May be given. The same applies to the search dog, and the degree of completion can be set to 6 to 7 that is specifically assigned to the search dog.

As described above, in the search assistance system according to the present embodiment, not only two-stage information indicating whether or not a search has been performed, but also information on the degree of search completion indicating how much search activity has been performed is a search activity completion area. Because it is included in the information, the degree of search can be confirmed step by step on the display unit based on this information, so that additional search activities were performed again in places where sweet searches were performed, and it was said that the victims that were overlooked were discovered Is possible.

The central processing unit may obtain the degree of completion in the search activity completion area information after further taking into account the topography and the like. FIG. 11 shows the configuration of the central processing unit of the present embodiment.

The central processing unit 900 includes a communication unit 910, a central control unit 920, a storage unit 930, an image analysis unit 940, a search required time calculation unit 950, and a search activity area information generation unit 960.

The communication unit 910 receives information on the current position and individual search activity completion area information transmitted from each transmission device. The received information is stored in the storage unit 930 and output to the search activity completion area information generation unit 960. The communication unit 910 also receives image data such as aerial photographs, moving images, and other satellite photographs via a public communication network or the like. These image data are stored in the storage unit 930 and are output to the image analysis unit 940.

The central control unit 920 controls the entire central processing unit 900.

The storage unit 930 stores the individual search completion area information and image data output from the communication unit. Further, the search activity area information generated by the search activity area information generation unit described later is stored. The storage unit 930 stores map information. The storage unit 930 may be arranged outside the central processing unit 900 in the form of a database, and may be connected so as to be communicable with the central processing unit 900.

The image analysis unit 940 analyzes the image data output from the communication unit 910. Specifically, since the time required to complete the search increases in places where destruction is severely advanced or places where a lot of rubble is washed away by tsunami, the degree of destruction in each area is analyzed. As a result of the analysis, the destruction coefficient obtained for each position is output to the search required time calculation unit 950.

FIG. 12 shows an example of the destruction coefficient obtained by the image analysis unit 940 for each position as a result of the image analysis. As shown in FIG. 12, the search target area is subdivided into ranges of every 5 square meters, and a destruction coefficient is associated with each subdivided position range and stored. Here, the numerical value in each square indicates the destruction coefficient in the position range, 0 indicates a normal state without destruction, and 7 indicates an abnormal state in which a catastrophic destruction occurs. Yes.

The search required time calculation unit 950 inputs map information from the storage unit 930, inputs a destruction coefficient for each position from the image analysis unit 940, and calculates a time required until the search is completed at each position. For example, a search for a place such as a park can be completed by looking at a glance at a glance, whereas in a building, the inside of each room must be checked, so the time required for completing the search differs. Therefore, the search required time calculation unit 950 calculates the time required for the search for each position in consideration of the topography at each position obtained from the map information, the layout of the building, and the like. Moreover, even if it is a building, the time required for a building destroyed by a tsunami or the like and a building that is not destroyed differ greatly. Moreover, even if it is an open place such as a park or road, it takes a lot of time if debris washed away by the tsunami accumulates. Therefore, the search required time calculation unit 950 obtains the basic search time required in each position range based on the map information input from the storage unit 930, and then obtains the destruction coefficient for each position obtained by the image analysis unit 940. As a filter, the time required for the search at each position is finally calculated to generate the search required time information.

FIG. 13 shows an example of the search required time information. As shown in the figure, the time required for the search is summarized for each position range. In FIG. 13, the center coordinates of each position range are shown as representatives, and the time required for the search is shown in association with a predetermined position range centered on the coordinates. The search required time information generated by the search required time calculation unit 950 is stored in the storage unit 930 and is output to the search activity completion area information generation unit 960.

The search activity completion area information generation unit 970 generates search activity completion area information based on the individual search activity completion area information input from the communication unit 910 and the search required time information input from the search required time calculation unit 950. Here, the search activity completion area information generation unit 970 compares the search time performed at each position indicated by the individual search activity completion area information with the required search time at the position, thereby determining the degree of search completion for the position. Is calculated. The search activity completion area information is finally generated by performing the calculation process for all the position ranges.

In calculating the degree of completion of search in the above calculation process, the calculation is performed after integrating the search activities performed so far. For example, it is indicated in the individual search completion area information from the transmission device owned by member A that member A has been conducting a search activity for 5 minutes for a certain position range, and then the individual search transmitted from the transmission device held by member B If the completion area information indicates that member B has performed a search activity for 3 minutes in the position range, the search activity completion area information generation unit 970 indicates that a search activity for a total of 8 minutes has been performed in the position range. presume. The search activity completion area information generation unit 970 obtains the degree of completion by comparing the accumulated search time with the search required time calculated by the search required time information selection unit 950. It may be configured in this way.

In addition, it is performed in consideration of the proficiency level of the search members included in the individual activity completion area information. That is, when certain individual activity completion area information is generated by a transmission device owned by a veteran member, the search time of each position range indicated by the individual activity completion area information is subjected to a predetermined filter to obtain the actual search time. Assuming that a long time search has been performed, the degree of completion in each position range is calculated by comparing the search time after the filter correction with the required search time.

In this way, the central processing unit generates the search activity completion area information after taking into account the information such as the actual degree of destruction, building, topography, etc., and other members' search ability, etc. be able to.

(Embodiment 6)
The transmission device according to the sixth embodiment further includes caution ventilation means for receiving search command information transmitted from the central processing unit and alerting the crew members. Hereinafter, the transmission apparatus according to the sixth embodiment will be described.

FIG. 14 is a diagram showing a configuration of transmitting apparatus 600 according to the sixth embodiment. The transmission device 600 includes a position detection unit 310, a communication unit 320, a storage unit 330, an input unit 340, a central control unit 350, a display unit 360, and an alerting unit 680. Here, since the position detection unit 310 to the display unit 360 are the same as the configurations described in the above embodiments, a part of the description is omitted.

Communication unit 320 receives search command information transmitted from the central processing unit. Search command information is information for the search support center that knows the current position and search status of each member based on the information on the current position transmitted from each transmitting device, etc. to instruct members to search individually It is. The single work command information includes at least information indicating the search position to be instructed and the identifier of the instructing transmission device.

The search command information received by the communication unit 320 is once output to the central control unit 350. The central control unit 350 determines whether the search command information input from the communication unit 320 matches the identifier of the own device, thereby determining whether the search command information is information addressed to the own device. Determine. When the search command information is information addressed to the own device, the search command information is output to the display unit and a warning signal is output to the warning unit 680.

When the alerting signal is input from the central control unit 350, the alerting unit 680 alerts the member who is the user that the search command information has been received. Specifically, the alerting unit 680 is an audio output unit or a vibration unit, and outputs a predetermined sound stored in advance or vibrates a vibration element when an alerting signal is input. Arouse.

When the search command information is input from the central control unit 350, the display unit is a position where the search command is issued at the position on the map based on the information regarding the indicated search position included in the search command information. A special icon is displayed together. Upon receiving the alert, the member identifies the position where the search command has been issued by checking the display unit, and performs search activities at the indicated position.

As described above, in the search support system according to the present embodiment, search command information is transmitted when a search support center that grasps the entire search situation wants to give a predetermined member a search instruction for a predetermined position. In addition, a configuration in which a member who has received this can perform a search activity at a specified position enables a search without omission. Specifically, when a staff member of the search support center finds a blind spot area where the search activity has not yet been performed on the display screen, the staff member of the search support center is closest to the blind spot area based on information on the current position transmitted from each transmitting device. An instruction to search for the blind spot area can be given to the member conducting the search activity at the place by transmitting the search command information. Since the search command information only needs to include information on the search position (coordinates) to be instructed and the identifier of the other party, it is possible to make an appropriate instruction with a small amount of information and to effectively use radio resources.

In addition, since the members are engaged in search activities and do not always look at the screen of the display unit, it is possible to appropriately notify the members of instructions from the search support center by providing a separate alerting unit.

(Embodiment 7)
The transmission apparatus according to the seventh embodiment further includes a configuration for notifying a rescue request to the search support center.

In rescue operations after a large-scale disaster, injured victims and, in some cases, bodies are discovered every moment. In addition, fire digestion and special handling of hazardous materials may be required. In this case, depending on the injured situation and number of victims, it is necessary to request an ambulance, a rescue helicopter, a rescue team, etc., and a fire fighting or special processing team for fires that occur. Here, it is desirable that an instruction can be given by conversation using the communication function of the transmission device or a separately owned mobile phone to the search support center or the firefighting headquarters. However, it is conceivable that a mobile communication network capable of high-speed communication, which has been widely used, is down after a major disaster, and usable radio resources are limited. In addition, since many members are active in a narrow area, if each member makes a call or the like with the search support center, the radio resource is punctured.

Therefore, the transmission device according to the seventh embodiment further includes a function of transmitting relief request information. Hereinafter, transmission apparatus 700 according to the seventh embodiment will be described. However, part of the description of the blocks described in the above embodiments is omitted.

  A member who is a user of the transmission device finds an injured person or the like, and executes a rescue request application installed in the transmission device when seeking relief. When the application is executed, a selection screen as shown in FIG. 15 is displayed on the display screen of the display unit.

FIG. 15 is a diagram illustrating an example of a selection screen displayed on the display unit at the time of a rescue request. On the selection screen, the rescue contents and the urgency level can be selected. The rescue content is a part for selecting the content of the rescue request, for example, and the pull bar is moved to select from items registered in advance. Rescue content includes: "Injury transport request", "Body transport request", "Relief team reinforcement", "Fire brigade dispatch", "Search dog dispatch", "Heavy equipment dispatch", "Special craft squad dispatch", "Relief team dispatch", "Lighting irradiation", "Others" "and so on. The urgency level indicates the urgency level of the request. For example, the user selects the urgency level of the rescue request from four levels. By selecting the “decision button”, the information selected on the selection screen is transmitted to the search support center as rescue request information together with the current position detected by the position detection unit. The search support center grasps the position and content of the request for rescue based on the rescue request information sent from the transmission device, and notifies the emergency team or the like waiting.

FIG. 16 is a diagram showing an example of another selection screen. In the selection screen of FIG. 16, in addition to “rescue content” and “emergency”, more detailed selections such as “severity”, “number of people”, and “transport method” are possible. The severity is information indicating the severity of the symptom of the injured person such as a serious injury, a minor injury, and a minor injury, and the number of persons is information indicating the number of the injured person, the corpse, and the rescue team. The transport method indicates a transport method for injured persons such as ambulances, helicopters, stretchers, and ships. In the affected areas, ambulances may not be able to enter depending on the location, and rescue by helicopter may be required from the sky. Therefore, since it will be turned back toward the rescue by an ambulance, the transfer method is notified in advance.

As described above, the transmission apparatus according to the present embodiment can appropriately perform rescue support with simple and small-capacity information. In search activities such as rescue activities, injured persons and the like are discovered every moment, and appropriate transportation and treatment are required. Here, the search members are constantly in charge of searching and do not have skills such as emergency treatment, and there are occasions when there are not enough people to carry them. Therefore, in such a case, the number of lives that can be saved can be increased by providing the transmission device with a function that can provide quick and appropriate rescue support.

In addition, when a dead body is found, search for “remaining body” is selected from the rescue contents, and information such as the location of discovery and the number of dead bodies is included in the relief support information and sent to the search support center. The search team can continue the search activities while grasping the location of the body at the center, so lifesaving can be given top priority. Until now, when a dead body was found, it could not be left as it was, so lifesaving and transportation were performed in parallel. However, since the location of the found dead body is recorded using this device, members can continue the exploration activities and can carry out the dead body transportation several days later, giving priority to lifesaving. The search system can be drawn.

As described above in each embodiment, the rescue / investigation support system of the present invention is composed of a transmission device and a central processing unit, and the transmission device includes detection means for detecting the current position, and detected current Transmitting means for transmitting position information relating to the position. The central processing unit includes a generating unit that identifies a position where a rescue operation or an investigation activity has been performed based on the position information transmitted from the plurality of transmission devices, and generates rescue / survey activity completion area information. . Therefore, since the status of rescue and investigation activities can be centralized and grasped at the rescue and investigation support center where the central processing unit is located, it is easy to grasp the positions where rescue and investigation activities were performed and where they were not performed. Thus, an appropriate instruction or the like can be made based on this information.

The central processing unit further includes transmission means for transmitting the generated rescue / survey activity completion area information to a plurality of transmission devices, the transmission device receiving the rescue / survey activity completion area information, and Display means for displaying a map around the current position detected by the detection means in a state in which the position where the rescue operation or the investigation activity has been performed and the position where the rescue operation has not been performed can be discriminated based on the rescue / survey activity completion area information; It can be set as the structure which further comprises. According to the said structure, since each member of the field who performs a rescue operation etc. can also grasp | ascertain the whole rescue activity condition sequentially, the efficiency of a rescue operation can be improved dramatically.

Here, if the transmission device further includes storage means for storing the map information, and the display means reads out the map information and draws and displays the map, the process of sequentially receiving the map information from the system side can be omitted. Therefore, it is good.

The transmitting device may further include generating means for generating individual rescue / survey activity completion area information, and the transmitting means may be configured to transmit the individual rescue / survey activity completion area information. Management and processing in the central processing unit can be simplified by generating and transmitting information indicating an area where the individual rescue operation performed by the owner of each transmission device is completed.

Here, the detection unit of the transmission device detects the current position at the first frequency, and the generation unit collects position information regarding a plurality of current positions detected at different times with the first frequency. The individual rescue / survey activity completion area information is generated, and the transmission means transmits the individual rescue / survey activity completion area information as information related to the current position at a second frequency lower than the first frequency. With this configuration, it is possible to effectively use limited radio resources. The detection means may be configured to obtain the detection time of the current position together and include the detection time according to the individual rescue / survey activity completion area information.

The transmission device further includes an input means for inputting a position range where the rescue operation or the investigation activity has been completed, and the generation means uses the position range input by the input means as the individual rescue / survey activity completion area information. If the transmission means is configured to transmit the individual rescue / investigation activity completion area information, the central processing unit side can grasp a more appropriate activity status.

  Here, the obtaining unit is a touch panel, and the generation unit generates a range selected by the touch panel from the map displayed on the display unit as the individual rescue / survey activity completion area information. It is still good because the activity completion position can be selected visually. Since the position corresponding to the point input on the touch panel, that is, the position range corresponding to the range surrounded by the user with a finger or the like can be generated as the individual rescue / investigation activity completion area information, it is easy to use.

Further, the transmission means transmits the position information related to the current position including identification information unique to the own apparatus, the reception means receives search instruction information, and the display means displays the search instruction on the map. By adopting a configuration in which the search instruction position indicated by the information is displayed in an identifiable state, it is possible to issue a necessary command to a necessary member from the central processing unit side that manages the information in an integrated manner.

In addition, the display method of the present invention receives a detection step for detecting a current position, a transmission step for transmitting position information relating to the detected current position, and information indicating a position where a rescue operation or an investigation activity has been performed. And a display step of displaying a map in a state in which a position where a rescue operation or an investigation activity has been performed and a position where it has not been performed can be discriminated based on the received information. The transmission method of the present invention includes a detection step of detecting a current position at a first frequency, and a generation step of generating a plurality of pieces of position information related to the detected current position and generating individual rescue / survey activity completion area information. And a transmitting step of transmitting the generated individual rescue / investigation activity completion area information at a second frequency lower than the first frequency.

In addition, it cannot be overemphasized that the description in each said embodiment shows an example, and can change suitably. It is also possible to combine the embodiments.

  In the above description, rescue activities and investigation activities are assumed as search activities, but they can also be used for other activities. Here, the search support center is called the rescue and investigation activity support center, the search activity completion area information is called the rescue and investigation activity completion area information, and the individual search activity completion area information is called the individual rescue and investigation activity completion area information. Sometimes.

The transmission device described in each of the above embodiments is also a so-called search assisting device, and can take the form of a navigation device, a mobile terminal device, a smartphone, a tablet, a position detection device, and other various devices having the above-described configuration. Needless to say. Moreover, when using it for a search dog, it can also take the form of a collar.

In addition, transmission and reception of various types of information from the transmission device described above to the central processing unit via a base station or the like may use a mobile communication network or other wireless communication system.

Further, the position detection unit, communication unit, transmission unit, storage unit, display unit, and individual search activity completion area information generation unit constituting the transmission device of the present invention may be designed to be incorporated in one device. It may be configured to be connectable to the outside through an interface such as a connector. For example, when the mobile communication network is down, when performing communication using satellite communication or the like, the transmission unit and the communication unit are considerably large. Therefore, in such a case, the transmission device can be configured to include a position detection unit, a storage unit, a central control unit, a display unit, and a connection interface unit, and not include a transmission unit or a communication unit. is there. In this case, the information regarding the current position detected by the position detection unit is output to a communication device installed outside via the connection interface unit. Such a configuration may be adopted. In this case, the device is not called a transmission device, but may be called a display device, a search assistance device, a rescue activity assistance device, or the like.

  Note that a camera unit for separately capturing an image may be attached to the transmission device. This is because it is useful for verifying the search situation later. In addition, it is more preferable that a still image or a moving image captured by the camera unit can be transmitted from the communication unit or the transmission unit to the central processing unit. The search support center can obtain more accurate information and can give a more appropriate command.

In addition, the central processing unit collects location information related to the current location transmitted from mobile communication terminal devices such as mobile phones possessed by general citizens to generate disaster location information, and sends the disaster information to the transmission device possessed by rescue workers. It may be configured to transmit person position information. Here, the location information of a plurality of victims is collected in the victim location information. Here, the mobile communication terminal device includes position detection means for detecting the current position and transmission means for transmitting information relating to the detected current position. The central processing unit transmits a position information transmission instruction signal for instructing each mobile communication terminal device to transmit the position information after the disaster occurs. Here, the position information transmission instruction signal is broadcasted using a common channel by broadcast or multicast. The mobile communication terminal device further includes a receiving unit that receives the position information transmission instruction signal, and a control unit that controls the position detection unit and the transmission unit based on the received position information transmission instruction signal. Is even better. The control means, when receiving the position information transmission instruction signal received by the receiving means, controls for causing the position detecting means to detect the current position, and controls for causing the transmitting means to transmit information regarding the detected current position. I do. Thus, the position detection means detects the current position based on the control of the control means, and the transmission means transmits information on the current position detected by the position detection means based on the control of the control means. By configuring in this way, the mobile communication terminal device that has received the position information transmission instruction signal automatically detects the current position when it is involved in a disaster and lays under a building, etc. Since the information regarding the position is transmitted to a pre-registered address (the central processing unit or a predetermined server address), the position of the victim can be grasped on the central processing unit side. Then, the central processing unit collects these pieces of information and transmits the disaster victim location information to the rescue team member's transmission device. When the transmission device receives the disaster victim location information in the communication unit, the transmission device is sent to the display unit, and the display unit displays the map on the drawn map based on the location information indicating the location of the disaster victim included in the disaster victim location information. In FIG. 5, a predetermined icon representing the victim is overlaid and displayed at the position indicated by the position information. Therefore, when an icon indicating the victim is displayed on the map displayed on the display unit, the rescuer preferentially performs the rescue operation because it is highly likely that the victim is captured at that position. be able to. Note that the mobile communication terminal device represented by a normal mobile phone is set so that the system cannot force the mobile communication terminal device to detect the current position and transmit the position information from the viewpoint of privacy. . Therefore, in the present invention, it is preferable that the mobile communication terminal apparatus is provided with setting means for setting the setting so that the position information can be forcibly collected from the system side when the predetermined condition is satisfied. It is. When such setting means is provided, the setting means sends position information to the system side in accordance with the following steps when a predetermined condition is satisfied in accordance with an instruction from the user from the input means of the mobile communication terminal device. Settings to be transmitted are performed, and setting information that summarizes the setting contents is stored in a storage unit such as a hard disk or a flash memory. The setting content here may be that the position information transmission instruction signal is received as a condition for transmitting the position information. Further, it may be an additional condition that a release instruction is not input from the user through the input means or the like within a certain time after receiving the signal. In other words, even if a disaster such as an earthquake occurs and a position information transmission instruction signal is transmitted from the system side having the central processing unit, a user who is not particularly damaged often does not want to notify the system side of the current position. it is conceivable that. Therefore, the mobile communication terminal apparatus has received the position information transmission instruction signal by the receiving means, and is waiting for whether the position information related to the current position is detected by the detecting means and transmitted by the transmitting means (position information transmission standby). It is still preferable to wait for a user's reaction for a certain period by displaying on the display means a notification screen for notifying that the mode is). When a cancel instruction for canceling transmission of the position information is input from the user who has seen the notification screen displayed on the display means within a certain period of time, the position information transmission standby mode is canceled. Since the own apparatus returns to the normal state, the transmitting means does not transmit the position information to the system side. Therefore, the user's privacy is maintained. On the other hand, a user who has a large scale of disaster and cannot move due to the underlayment of a building cannot input a release instruction within a certain period. Therefore, after a certain period of time, position information indicating the current position from the mobile communication terminal device Is transmitted to the system side, and the location information of the mobile communication terminal device is included in the disaster victim location information by the central processing unit in the system, so the rescue crew member having the transmission device that has received the disaster location information The possibility of rescue can be increased. Here, it is desirable that the certain period is between several minutes to several hours. When there is a disaster, there is often no room for viewing the display screen of the mobile communication terminal device, so if the standby period is too short, the location information is transmitted without noticing. Also, since 72 hours is the standard for the probability of death in the event of a disaster, a certain period of time may be shorter than 72 hours so that you can get to know your presence sooner. desirable. Normally, if there is enough time, the user will be able to see the display screen once. Therefore, it is easy to know and cancel that it is a standby mode for whether or not to send location information accompanying the occurrence of a disaster. This is because it can be determined whether or not. As described above, the mobile communication terminal device possessed by the general public includes the position detection means, the transmission means, the reception means, and the control means having the above-described functions, so that it can be rescued in an emergency while maintaining privacy. It is possible to provide an apparatus and a system that allow a hand to be extended. It is further preferable that the mobile communication terminal apparatus further includes a setting unit having the above-described functions, an input unit, a storage unit, and a display unit. Further, the transmission device possessed by the rescuer (rescue crew member) includes a receiving unit that receives the disaster victim position information, and a display unit that displays a predetermined icon on the map at a position included in the disaster victim position information. The rescuer can appropriately perform the rescue operation without waiting for a special rescue instruction from the rescue support center. Here, the location information transmission instruction signal includes an urgency level or an importance level according to the magnitude of the disaster, and the setting means in the mobile communication terminal device determines whether to transmit information about the current location. As a condition, it is still preferable to set a reference urgency level or importance level and store the setting information in the storage means. When the reception means receives the position information transmission instruction signal, the control means reads the setting information stored in the storage means, and the position where the urgency or importance set in the setting information is received. It is even better if the control for shifting to the machine mode is performed when the degree of urgency or importance included in the information transmission instruction signal is lower.

In addition, the position detection unit, the transmission unit, the communication unit, the central control unit, the individual search activity completion area information generation unit and the like described above may be realized using a semiconductor integrated circuit. Here, the integrated circuit may be referred to as LSI, VLSI, or ULSI. The central control unit may be referred to as a CPU (Central Processing Unit).

Moreover, the individual search activity completion area information generation unit may be implemented as a part of the CPU. The generation process performed by the individual search activity completion area information generation unit may be performed by hardware, or may be configured to be executed by software using a program. The central control unit corresponding to the individual search activity completion area unit reads the program recorded in the recording unit (not shown), decodes and executes the generation process performed by the individual search activity completion area information generation unit. It may be configured to do.

In addition, each process performed by the image analysis unit, the search required time calculation unit, and the search activity area information generation unit included in the central processing unit may be performed by hardware, or may be performed by software using a program. You may be comprised so that.

In addition, each process performed by the control unit or the setting unit included in the mobile communication terminal device described above may be performed in hardware, or may be configured to be executed in software using a program. good.

Further, the central processing device described above may be constructed as a system composed of a plurality of devices. That is, the functions of the central processing unit described above may be incorporated in different devices, and may be arranged in the search support center as a search support system having these plural devices.

A detection step for detecting a current position; a transmission step for transmitting position information relating to the detected current position; a reception step for receiving information indicating a position where a rescue operation or an investigation activity has been performed; and the reception Naturally, the present invention includes a display method that includes a display step of displaying a map in a state in which a position where a rescue operation or an investigation activity has been performed and a position where it has not been performed can be determined based on the information that has been performed. Further, it may further include a reading step for reading map information and a generation step for generating individual rescue / survey activity completion area information. Further, the display step may be a display step for displaying the degree of completion of the rescue operation or the investigation activity performed in a state where it can be determined.

A detection step of detecting the current position at a first frequency; a generation step of generating a plurality of pieces of position information related to the detected current position to generate individual rescue / survey activity completion area information; and the generated individual rescue. -The transmission method which has the transmission step which transmits investigation activity completion area information by the 2nd frequency less than said 1st frequency is naturally contained in this invention.

In addition, a search assistance program that causes the computer to execute the above-described method, a detection process that causes the position detection unit to detect the current position at a predetermined frequency, a transmission process that causes the transmission unit to transmit information about the detected current position, Display processing for displaying a map in a state where it is possible to discriminate between the position where the rescue operation or the investigation activity has been performed and the position where the rescue operation or the investigation activity has not been performed based on the information indicating the position where the rescue operation or the investigation activity has been received. Naturally, a rescue / investigation activity assisting program for causing a computer to execute the above is also included in the present invention.

  The transmission device according to the present invention can be used for various searching activities when rescue operations are performed by human naval tactics when an emergency such as a disaster occurs, or when investigation activities such as terrorism are performed.
