Description

  The present invention relates to a system and a search simulator for supporting search activities.

  When a large-scale disaster occurs, an extensive search by a large number of searchers may be required to search or rescue the victims. Such searches include, for example, searching for victims buried in volcanic ash in the event of an eruption disaster, searching for victims buried in sediment, mudflow, etc., in the event of a landslide or mudflow disaster, a major earthquake or tsunami When a disaster occurs, there is a search for lost persons buried in rubble or earth and sand, lost persons, sunken persons, etc. Moreover, although it is small in scale, a plurality of searchers may be required to search for objects (remains, weapons, etc.) dumped in rivers and swamps and to search for climbers.

  The conventional procedure for conducting a search in a large-scale disaster is as follows. First, the organization that first received disaster occurrence information, for example, the Ministry of Defense, the police station, the fire department, the local government, etc., establishes the disaster countermeasure headquarters. Next, at the Disaster Response Headquarters, the map containing the disaster occurrence area is spread on the desk, and the search commander, etc., with the cooperation of intellectuals and experienced people who are knowledgeable in the geography, topography, and situation of the disaster occurrence area. Set the search range while watching. Subsequently, the number of searchers required and the position of the searchers are determined according to the size (area and situation) of the set search range, and the same number of searchers are convened. All the convened searchers and search commanders share information on the search range and location, and then head to the search site. At the search site, the search conductor collates the map at hand with the search range of the site and designates the position of the searcher again. In this way, each searcher arrives at the designated location under the direction of the search commander and starts the search.

  In the conventional search procedure as described above, it took a considerable amount of time to prepare the map, check the map, set the search range, and share information on the search range and the arrangement position.

  If the scale of the disaster is large, the people involved in the search are divided into multiple groups, and after the search range is set in one group, the set search range is checked while looking at the same map in the same way in other groups. . If the setting contents are changed, it is necessary to reset the search range and arrangement position in all groups again. Accordingly, it is not uncommon for a considerable amount of time to pass before all searchers share information on the search range and arrangement position and leave for the search site.

  In addition, after the search activity is executed, if the search of the entire search range is not completed in one day, the remaining part of the search is continued on the next day. In that case, the last search activity end position is confirmed, and the search activity is resumed from there. However, since the previous search activity end position is confirmed based on the memory in the past, the previous search activity end position becomes unknown due to, for example, ash, rain, snow, strong wind, etc. Since it became impossible, the efficiency of search activities could be reduced.

  It is said that whether or not a person can be rescued within 72 hours from the time of the disaster will affect the life and death of the victim. In the conventional search procedure as described above, it is often difficult to rescue within 72 hours, and therefore improvement is desired.

  In addition, depending on the situation of the disaster area, a heavy load is applied to the searcher, which may cause abnormal health, hinder the search activity, the searcher himself may be the target of rescue, or may die . For this reason, it is desirable to consider the health management and protection of searchers.

  Patent Literature 1 discloses a search support system that supports a search for a deaf person. However, in this search support system, when the search request information is received from the search requester terminal, the position information received from each searcher terminal, the map information stored in the database, and the information about the search target received from the search requester terminal Based on the above, a search map representing the position where the search object has disappeared, the past discovery position, the position of the searcher terminal, etc. on the map is generated and transmitted to the search requester terminal. Therefore, even if such a search support system is applied to a search for a search target of a large-scale disaster, it may not be possible to rescue within 72 hours, and the health management and protection of searchers are not taken into consideration.

  The receiving means 101 receives search case file data, map data, position information and health information of each searcher, search requirement data, search progress data, etc. sent from the management device 200 via the network.

  The input means 102 may be a known input means such as one that generates and outputs a signal by manual operation of a keyboard, mouse, touch panel or the like, or one that recognizes speech and converts it into an electrical signal for output. it can.

  The disaster response headquarters receives disaster occurrence information (or distress occurrence information, the same applies hereinafter) over the phone, etc., and information required for search activities based on the received disaster occurrence information when receiving a search request ( Search information) is input from the input means 102. Search information includes, for example, the name of the search case, the name of the area to be searched, the type and scale of the disaster, the number of missing persons, the search range, the searchable time of the day or the searchable time within 72 hours, and the searchable search There are number of members.

  The disaster response headquarters inputs the search information and creates a search case file each time a search case occurs. In addition, the input unit 102 can perform an operation for requesting transmission of map data and search progress data. Furthermore, when the disaster countermeasure headquarters looks at the map displayed on the display means 106 based on the transmitted map data and determines the search range, the search range can be input.

  The processing means 103 creates a search case file according to a predetermined format according to the input content from the input means 102. Further, the processing means 103 changes the display angle (viewing angle) by the display means 106 of the search area map received from the management device 200 in response to an input command from the input means 102. Further, the processing means 103 displays the search progress received from the management apparatus 200 (including the movement trajectory of each searcher) and the search requirements (required search time and / or number of required searchers) in an easy-to-view format. May have a function of editing.

  The transmission means 105 transmits the search case file data created by the processing means 103 to the management apparatus 200, and also receives a map data request signal, search range designation information, search progress status data request individually input from the input means 102. The signal is transmitted to the management apparatus 200 via the intranet N1 (or network, hereinafter the same).

  The display means 106 displays the search case file created via the input means 102, the map sent from the management apparatus 200, the search requirements, and the search progress status using a known display technique.

  Then, the control means 107 comprehensively controls each of the above-mentioned means 101 to 106 so that their functions can be exhibited smoothly.

[Management device]
As illustrated in FIG. 3, the management device 200 provided in the data center includes a receiving unit 201, a processing unit 202, a storage unit 203, a transmission unit 204, and a control unit 205.

The receiving means 201 is sent from the search case file data, the map data request signal, the search progress status data request signal and the postscript searcher terminals 400 _{1 to} 400 _n sent from the sending means 105 of the headquarters terminal 100 via the network. Receive location information, searcher health information, and search target discovery information.

The processing means 202 performs processing of items described below.
That is, (a) when the receiving means 201 receives the search case file data from the headquarters terminal 100, an identification code is added to the search case file data, the search case folder is created in the storage means 203, and Store search case file data in a folder. Thereafter, information exchange between terminals regarding the search case is performed using the same identification code. As a result, when another search case occurs in the disaster response headquarters thereafter, information can be exchanged in distinction from other search cases.

  (B) When the receiving means 201 receives the map data request signal, the processing means 202 makes an external map data provider via the transmitting means 204 based on the search target area name in the search case file data. The requested map data is requested to be downloaded, and the downloaded map data is stored in the search case folder of the storage means 203. Instead of downloading from an external map data provider, map data including the search area name is read out from the map data stored in the database of the storage means 203, and the map data is used for searching. You may make it store in a search case folder as a map.

  (C) As one of important functions, the processing means 202 calculates search requirements (search required time and required number of searchers) based on search information sent from the headquarters terminal 100, and stores the calculation results. Hold in the means 203.

  In order to calculate the time required for search and the required number of searchers based on the search information, first, the total area of the search range is obtained from the search map based on the search range in the search information. The total area of the search range can be obtained from the scale of the map and the area of the specified search range on the map.

Next, the following Formula 1, Formula 2, Formula 3 and Formula 4 are calculated to obtain the required search time, the number of required searchers, and the number of shifts.
A / a = T ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ Formula 1
h = hD × 3 Equation 2
(T / h) × S = N Equation 3
S = hD / P Equation 4
Where A is the total area of the search range,
a is the area that can be searched for 1 hour per person,
T is the time required to search the entire area (search time)
h is the search time that can be entered within 72 hours (3 days),
S is the number of shifts per day,
hD is the search time per day,
P is the search time per person that can be entered per day,
N is the required number of searchers.

  The search requirements (search time required and number of required searchers) calculated and held based on the search information sent from the headquarters terminal 100 of the processing means 202 are in response to a request from the headquarters terminal 100 or the conductor terminal 400. And transmitted to the terminal via the transmission means 204.

  When the number of searchers that can be called is less than N, it is necessary to increase a and / or hD. Further, when the number of searchers that can be called is greater than N, a and / or hD can be reduced. Thus, a and / or hD can be set to some degree of flexibility depending on the number of searchers that can be called.

(D) As will be described later, when the receiving unit 201 newly receives information from each of the searcher terminals 400 _{1 to} 400 _n , the processing unit 202 generates each searcher folder, and the searcher folder The information received, that is, the position information and the health information is recorded and accumulated until a cancellation command is received from the headquarters terminal 100 when the disaster countermeasure headquarters is dissolved. This position information is latitude / longitude transmitted by searcher terminals 400 _{1 to} 400 _n having a positioning function, as will be described later.

(E) Each time the processing means 202 receives position information from the searcher terminals 400 _{1 to} 400 _n, it records the position information and the reception time in the corresponding searcher folder. By continuing to receive and record the position information and the reception time, the movement trajectory of each searcher is created. Then, the latest position information and movement trajectory are overlaid and recorded on the corresponding latitude / longitude of the search map stored in the search case folder. Thereby, the search map shows the search range, the current position of each searcher in the search range, and the movement trajectory up to that point.

  (F) The processing means 202 can also predict the progress of the search activity. In order to predict the progress of the search activity, the processing means 202 provides environmental information such as the area of the searched range in the search range (region), the terrain (gradient) and the presence / absence of obstacles, and up to that point. Based on the movement trajectories of all searchers, the movement speed (average speed) per unit time or unit area is obtained from the time and movement distance required for the movement from the search activity start position to the current position. Then, based on environmental information such as the area of the unsearched area in the search area (region), topography (slope), and the presence or absence of obstacles, the time required to complete the search for the unsearched area (progress status) Predict. The predicted progress status is stored in the storage unit 203 as progress status prediction information.

The stored progress prediction information can be displayed on the display means of the terminals 100 and 300 by accessing the management apparatus 200 from the headquarters terminal 100 and the conductor terminal 300. Accessed from search membered terminal 400 ₁ to 400 _n may be able to see the progress prediction information.

  If it is difficult to rescue within 72 hours with the predicted progress, the disaster prevention headquarters or search commander (hereinafter referred to as the commander) will search for the number of searchers to carry out the rescue within 72 hours. You can increase the number of shifts, extend the search time, and so on. In other words, according to the present embodiment, the search support system confirms the progress of the progress so far and predicts the future progress without taking the labor and effort for the conductor to visually check the progress of the search site. Then, based on the prediction, command can be performed to achieve rescue within 72 hours.

(G) The processing means 202 further receives the searcher's health information periodically sent from the searcher terminals 400 _{1 to} 400 _n , as will be described later. The health information of the searcher is compared with the health information at the time of the health of the searcher stored in the storage means 203 to automatically diagnose whether there is any abnormality in the health state. When the diagnosis result is obtained, the diagnosis result is stored in the searcher folder of the searcher in the storage unit 203.

  If the processing means 202 does not have a diagnostic function, the received health information is transferred from the management apparatus 200 to the designated medical institution (600), diagnosed by the medical institution, and the diagnosis result is received by the management apparatus 200. And you may make it store in the searcher folder of the said searcher of the memory | storage means 203. FIG.

  (H) When the result of the searcher's diagnosis stored in the storage means 203 is abnormal health, the processing means 202 outputs a signal indicating that the searcher is abnormal in health, via the communication means 204. It transmits to the headquarters terminal 100 and the conductor terminal 300. The headquarters terminal 100 and the conductor terminal 300 that have received this health abnormality signal blink the light of the searcher's presence position display portion on the search map or color it with a specific color on the display means. The occurrence of the person is informed and the location is displayed.

  (I) The processing means 202 further has a function of performing a search simulation when the management apparatus 200 receives a training request signal from the headquarters terminal 100. That is, the management device 200 operates as a search simulator when receiving a training request signal. However, a search simulator independent of the management apparatus 200 may be configured.

[Search simulator]
The search simulator performs the following operations.
<I> Information specifying an assumed disaster occurrence area transmitted from the headquarters terminal 100, such as a mountain name (mountain name), a latitude / longitude, and a city name, is received.
<Ii> Based on the received disaster occurrence area designation information, a map including the assumed disaster occurrence area is acquired and transmitted to the headquarters terminal 100.
<Iii> The disaster response headquarters looks at the map displayed on the headquarters terminal 100, specifies the search range, and also finds the search difficulty estimated from the topography, slope, rock presence, forest density, etc. of the search range. The response capability is input from the input unit 102 and transmitted from the transmission unit 103 to the management apparatus 200. The processing means 202 of the management apparatus 200 that has received the search range, the search difficulty level, and the response capability calculate search requirements for realizing rescue within 72 hours.

  The response capability is the time during which a search activity per day can be performed in a bright daytime (the time when search activity is possible) or the number of searchers who can be dispatched from the disaster response headquarters (the number of possible mobilizations). When the searchable activity time is input, the processing means 202 calculates the number of searchers necessary for realizing the rescue within 72 hours. Further, when the mobilizable number is input, the processing means 202 calculates the time required for the search activity necessary for realizing the rescue within 72 hours.

  Therefore, the disaster response headquarters and the conductor can input the search information for the search training, and can rescue within 72 hours within the specified search range of the assumed disaster occurrence area by the search simulator. Estimate search requirements (time required for search activities or required number of searchers). Therefore, it is possible to quickly and appropriately plan for searcher convocation and search time allocation.

  Above, at the time of training, the disaster occurrence area designation information assumed from the headquarters terminal 100 is transmitted to the management device 200 by the search simulator, so that the rescue within 72 hours within the designated search area of the assumed disaster occurrence area can be achieved. The number of searchers required to complete the search or the time required for the search activities was predicted. When an actual disaster occurs, the headquarters terminal 100 transmits the name of the area to be searched to the management apparatus 200. Similarly to the above, the number of searchers or searches necessary for rescue within 72 hours in the disaster occurrence area Predict the time required for activities and contribute to the proper conduct of the conductor.

  As illustrated in FIG. 4, the storage unit 203 includes a search case folder M1, a map data memory M2, and a plurality of searcher folders F1 to Fn. The search case folder M1 is created for each search case, and search case file data is stored in the search case folder M1. The map data memory M2 stores map data downloaded from an external map data provider. When using original map data instead of downloaded map data, the storage means 203 is provided with a database storing map data of various locations.

  The headquarters terminal 100 or the conductor terminal 300 has a function of using the map data received from the management device 200 to change and display the map direction so as to match the map observation direction in response to a map display direction switching request. It is preferable to provide. If the orientation of the map can be changed, it will be easier to examine which direction the searcher should proceed in order to facilitate the search activity.

  The searcher folders F1 to Fn are provided for individually storing information related to each searcher. Each searcher folder is provided with a first storage area a1 to a third storage area a3 as shown in FIG. The first storage area a1 stores the position information received from the searcher terminal 400. In the second storage area a2, when the next new position information is stored in the first storage area a1, the position information previously stored in the first storage area a1 is transferred to the second storage area a2, It is accumulated sequentially and stored as searcher's movement trajectory information. The third storage area a3 stores health information received from the wearable terminal 500 worn by the searcher.

[Conductor terminal]
The conductor terminal 300 is a terminal carried by the conductor. The conductor terminal 300 may be basically the same as the searcher terminal 400. However, since the searcher often searches in a harsh environment and situation, it is desirable that the searcher terminal 400 be as small and light as possible. On the other hand, the conductor should give a prompt and accurate command to the searcher while monitoring the display contents of the conductor terminal 300, monitor the health condition of the searcher, and exchange information with the disaster response headquarters. Therefore, the conductor terminal 300 is preferably a terminal that is easy to confirm on-site operation and screen display, such as a tablet that satisfies the dustproof and waterproof standards.

[Searcher terminal]
The searcher terminal 400 is a portable terminal that does not become an obstacle to the search activity. For example, a smart phone that satisfies the dustproof and waterproof standards can be used. As shown in FIG. 5, the searcher terminal 400 includes an input unit 401, a control unit 402, a communication unit 403, a positioning unit 404, a display unit 405, and a storage unit 406.

  When the searcher terminal 400 is turned on, the control unit 402 puts the communication unit 403 and the positioning unit 404 into a movable state. The positioning means 404 is a GPS (Global Positioning System) or other known positioning means, and always measures the current position and outputs position information. The communication unit 403 transmits the position information to the management apparatus 200 periodically, for example, at intervals of 5 minutes. The communication unit 403 performs short-range communication with the searcher's wearable terminal 500 described later. When the health information is received from the wearable terminal 500, the health information is also transmitted to the management apparatus 200 when the position information is transmitted.

  When the management device 200 is accessed from the searcher terminal 400 using the input means 401 and the communication means 403 and the case name or the case code is input, the management device 200 reads the case file data of the case and sends it to the searcher terminal 400. Send. Therefore, each searcher can download the map of the search area and the movement trajectory of each searcher from the management device 200 using his / her searcher terminal 400, and display it on the screen by the display means 405 for viewing.

  When the searcher finds the victim during the search, he / she operates the input means 401 of the searcher terminal 400 to start the discovery report application and operates a predetermined key to select the victim. Distress discovery information indicating that it has been discovered can be transmitted from the transmission means 405 to the management apparatus 200.

  When receiving the victim discovery information, the management device 200 stores the victim discovery information together with the location information of the searcher terminal 400 in the searcher folder corresponding to the searcher terminal 400 that transmitted the victim discovery information. In addition, a flag is added to either the stored position information or victim discovery information. Therefore, when the search map is called and displayed at any of the headquarters terminal, conductor terminal, or searcher terminal, the location where the victim is found is displayed in the search map with flashing lights or specified colors. The

[Wearable terminal]
The wearable terminal 500 is composed of, for example, a microcomputer attached to a wristband that satisfies dustproof and waterproof standards, and is attached to a searcher's arm or the like to acquire health information (vital information) of the searcher. is there. That is, wearable terminal 500 has a sphygmomanometer, a heart rate monitor, and a thermometer, and measures a wearer's blood pressure, heart rate, skin temperature, calorie consumption, and the like. Wearable terminal 500 has a short-range communication function, and communicates with searcher terminal 400 of the searcher wearing wearable terminal 500. Then, the acquired health information is transmitted to the searcher terminal 400.

  The searcher terminal 400 that has received the health information transmits the health information to the management apparatus 200. The processing means 202 of the management apparatus 200 diagnoses the health state with respect to the received health information using a known diagnosis algorithm. When it is diagnosed that the health condition is abnormal, it is registered in the searcher folder of the searcher in the storage means 203. Injuries, etc. cannot be detected by wearable terminal 500, so when an injured person who needs treatment or relief, the investigator uses the searcher terminal 400 to talk to the conductor or the disaster response headquarters to provide the necessary rescue. Can be requested.

  Even if there is no abnormality in the health condition of the searcher, if the health information is constantly transmitted from the wearable terminal 500 to the searcher terminal 400 and is always transmitted from the searcher terminal 400 to the management device 200, the communication load and the processing load of the management device 200 are increased. It can be a problem. Therefore, the wearable terminal 500 or the searcher terminal 400 has a diagnosis function, and transmits the wearable terminal 500 to the searcher terminal 400 or the searcher terminal 400 to the management apparatus 200 only when it is diagnosed that there is an abnormality in the health condition. It is preferable.

  When the health abnormality of the searcher is registered in the management device 200, the subsequent search map is displayed with the blinking indicating the health abnormality added to the position information of the searcher. Therefore, the conductor who is looking at the conductor terminal 300 can easily notice the blinking and know where the abnormal health person has occurred. Then, it is possible to instruct the searcher near the abnormal health person to confirm the state of the abnormal health person or to rescue, from the conductor terminal 300 via the searcher terminal 400.

  Therefore, if a searcher who is searching for an abnormality in his / her health condition due to overwork, injury or illness can respond promptly, this search support system can be used for the health management of the searcher. It is something that is fully considered.

  In addition, the calorie consumption during the search activity of the searcher varies depending on the situation of the search area. It is necessary to consider rest time and food supply time according to the amount of calories consumed. In the past, the food supply staff did not have an appropriate guideline for the timely determination of food supply to the searcher, and as a result, the searcher continued the search activities while hungry, resulting in inefficiency due to lack of power and overwork. There was a high possibility of becoming.

  When the wearable terminal 500 is provided with calorie consumption measuring means, there are the following advantages. That is, the calorie consumption measurement value during the search activity is recorded in time series, and when the measurement value exceeds the threshold, it is transmitted from the searcher terminal 400 to the management device 200 for recording. And the time when the next measured value exceeds a threshold value is estimated from the time interval of the time when the threshold value before and after the same searcher exceeded the threshold value. Therefore, the time when rest or / and food supply is required can be predicted, so that timely rest or timely food supply is possible. Therefore, it is possible to prevent search workers from overworking and reducing the efficiency of search activities.

[Consistent action description]
Finally, the consistent operation of the search support system according to the present embodiment when it is assumed that a disaster has occurred will be described with reference to the flowchart of FIG.

When a search request is included in the disaster occurrence information received by the disaster response headquarters, this search support system is activated.
<Operation of headquarters terminal>
First, in the headquarters terminal 100, the input means 101 is operated to search information, that is, the name of the search case, the name of the disaster place, and the type of disaster (for example, volcanic eruption, landslide, landslide, avalanche, earthquake collapse, flood, etc.) The search case file is created by inputting the scale size (S11. S11 is a step number. The same applies hereinafter). Then, the created search case file data is transmitted to the management apparatus 200 by the transmission means 105 (S12). The transmitted search case file is stored in the headquarters terminal 100 and is kept displayed on the screen by the display means 106. Next, the headquarters terminal 100 requests the management apparatus 200 to transmit map data including the disaster occurrence place (S13).

<Operation of management device>
In response to the map data transmission request (when Y in S21), the management apparatus acquires map data including the requested disaster occurrence location (S22) and transmits it to the headquarters terminal 100 (S23).

<Operation of headquarters terminal>
When map data is sent from the management device 200 (Y in S14), the map data is stored in the storage means 104 and displayed on the screen by the display means 106 (S15). Therefore, the disaster response headquarters looks at the map displayed on the screen, confirms the disaster occurrence point, area, etc., referring to the disaster occurrence information received earlier, etc., and specifies the search range appropriately. (S16) A search map is created (S17), and the search map is overwritten and stored in the storage means 104. Further, the search map is transmitted to the management device 200 (S18).

<Operation of management device>
The management device 200 calculates a search requirement for the search range specified on the received search map (when Y in S24) (S25), and transmits the calculation result to the headquarters terminal 100 and the conductor terminal 300 (S26). ).

  As a reference for calculating the search requirement, the management device 200 calculates the total area A of the search range, the average value a of the area that can be searched per searcher per hour, and the average of the time during which search activities can be performed per day. Enter the value hD. If the search time is expected to be long, the shift number S is also input.

  a is the average value of the area that can be searched per hour per searcher obtained from past behavior records in flat land, slopes with various slopes, forest zones with various tree densities, and wasteland with various rubble . In the storage unit 203 of the management device 200, a plurality of types of average values a corresponding to the search difficulty level due to such a difference in the environment of the land are stored as a database. Alternatively, it may be possible to express the difficulty of walking in other places as a numerical value using a flat ground as a standard, and obtain the search requirement by multiplying the standard value by the inverse of the numerical value. The degree of search difficulty can be estimated from the density of the contour lines of the three-dimensional map (3D map), the degree of curvature, and the like. Since hD is often limited to bright hours during the day, it varies depending on the season.

An example will be described. Search time P is 2 hours per person total area A of the search area of the flat land is 60,000M ^2, can mean a is 100 m 2, ¹ day on of the area that can be searched on a flat place for searching membered person per hour, If the search time hD per day is 8 hours, the search time T for the total area A is 600 hours from the formula 1 {(A / a) = T}, and 72 hours from the formula 2 {h = hD × 3}. The search time that can be entered within (3 days) is 24 hours, and the required shift number S is 4 from the formula 4 {S = hD / P}, so it is necessary to complete the search activity within 72 hours. The number N of searchers is 100 from the formula 3 {(T / h) × S = N}.

  As described above, the management apparatus 200 automatically sets search information based on the search range specified on the search map, calculates search requirements for the specified search range (S25), and calculates the calculation result to the headquarters. It transmits to the terminal 100 and the conductor terminal 300 (S26).

<Operation of headquarters terminal>
The headquarters terminal 100 that has received the calculated search requirement displays this on the screen (S110), so whether the disaster countermeasure headquarters and the conductor can convene searchers with the required number of searchers displayed. Can be considered. If convocation is possible, promptly convene the number of searchers displayed, confirm that each searcher has carried a searcher terminal, and use the projector prepared in the disaster response headquarters to search from the headquarters terminal 100 The map data is transmitted, and the specified search range is confirmed and the location of each searcher is specified while viewing the search map on the large screen.

  FIG. 9 shows that the search range is specified by an ellipse in the map data transmitted from the management device 200 to the headquarters terminal 100 assuming that the volcanic eruption disaster occurred near the summit of Mt. Asama in Tsumagoi Village, Gunma Prefecture. This is a generated search map. A small black dot in the ellipse indicates a temporary arrangement position designated by the searcher. In this way, after the disaster response headquarters, conductor, and all searchers share information, they head to the search site.

  If it is impossible to convene, the variable number of Equation 2 is fixed using the input means 101, and the other variable numbers are adjusted so that the equation is satisfied, so that the rescue within 72 hours is surely realized. Therefore, the search requirements can be set flexibly.

  If the search information is not registered in the database of the management device 200 in advance, the search condition is determined based on the obstacles such as the topography and the slope of the search range by looking at the contour lines of the map displayed on the search range screen. Even if the information A, a, hD, P is estimated, input from the input means 101 of the headquarters terminal 100, and transmitted to the management apparatus 200, substantially the same effect can be obtained.

The conductor collates the search range displayed on the conductor terminal 300 at the search site with the site, places each searcher in the correct placement position, and instructs the search direction to start the search activity. With the start of the search activity, the management apparatus 200 replaces the temporary arrangement positions of all searchers on the search map with the correct current positions based on the position information transmitted from the searcher terminals 400 _{1 to} 400 _n. It is done. The moving loci of the search members are generated by temporal accumulation of positional information transmitted from the management apparatus 200 in the search membered terminal 400 ₁ to 400 _n, the movement trajectory is displayed on the search map. In FIG. 9, the line with an arrow extending from the small black spot within the search range of the ellipse indicates the movement trajectory of the searcher every predetermined time, for example, every 5 minutes. The arrow indicates the direction of movement. The number of arrowed line segments increases as the distance traveled by each searcher at regular intervals increases.

  That is, search progress status data is constructed in the management device 200. Therefore, the disaster countermeasure headquarters and the conductor download the search progress data periodically or at any time using the headquarters terminal 100 and the conductor terminal 300 (S112 and S113 in FIG. 6) and display them on the screen. The search progress can be grasped at hand (S114 in FIG. 6).

  Therefore, the conductor conducts an appropriate command in response to his / her circumstances to achieve rescue within 72 hours while observing the search progress on the conductor terminal 300, and the increase / decrease of the searcher (including the increase / decrease in the number of shifts) and placement. The position can be changed, the moving direction can be adjusted, or the search time can be extended or shortened or stopped. Therefore, the search and rescue within 72 hours can be executed efficiently. In addition, it is possible to significantly shorten the time from the acceptance of the search request to the start of the search activity.

  Since the movement trajectory is stored in the storage means 203 of the management apparatus 200, the search activity for the entire search range was not completed in one day. Since the position is obvious, the search operation can be resumed quickly from the correct position. Accordingly, duplication of search positions and omissions are prevented, and search efficiency is improved.

  Of course, if all of the search objects are not found even after 72 hours have passed since the start of the search, the search activity is normally continued. Therefore, after the search progress status is displayed in S114 of FIG. 6, the processes from S112 to S115 are repeated until a search activity end signal is input at headquarters terminal 100 (Y in S115).

  In the above embodiment, the search target discovery information is displayed on the search map. However, the method of transmitting the search target discovery information to the disaster countermeasure headquarters or the conductor may be any other method. Good. In addition, the above embodiment is premised on being applied mainly to a search in the event of a large-scale disaster that requires several tens of searchers. However, the search support system according to the present invention is suitable for a small-scale search where less than a dozen searchers are required, or when searching for dead bodies or weapons that have been abandoned or dumped in forests or rivers. Thus, it is effective even if it is applied when there is no search time limit of 72 hours or less.
