In recent years, mountaineering has been attracting attention as leisure and sports, and in fact, the number of climbers tends to increase. Some climbers are skilled and some are inexperienced. In addition, not only inexperienced mountaineers but also experienced mountaineers, when climbing inexperienced mountains, under the circumstances where some damage is expected, nevertheless, a psychological phenomenon called normalcy bias occurs. It can occur, which can lead to unforeseen circumstances such as distress (for example, a pedestrian deviating from the normal route).

However, in the above-mentioned conventional technique, the climber who may be in a psychologically panic state can judge whether he / she has lost his / her way, whether there is a risk of distress, and to avoid the distress. We have no choice but to decide what to do and whether or not we were really in distress.

Therefore, this conventional technique assists the climber in calmly determining whether or not he / she has lost his / her way before he / she is in distress, and also assists in calmly determining whether or not there is a risk of distress. Nor can it assist in choosing the right actions to avoid a distress when there is a risk of distress.

The problem of route deviation, in which pedestrians deviate from the regular route, can also occur in activities other than mountaineering. For example, in an environment where pedestrians tend to lose their sense of direction, for example, when walking in a natural environment such as a forest or grassland, a tour passage in an unfamiliar factory, or because the pedestrian himself is immature, such as a child or an elderly person. It can also occur when walking on school roads or walking paths.

Therefore, there is a demand for a pedestrian abnormality determination technique that detects that the walking state of a pedestrian is abnormal during walking and notifies the pedestrian of the result to warn the pedestrian.

In addition, it is a technology to search for a pedestrian who is in distress while walking with a drone, and by switching the communication method that can be used with the drone according to the communication status of the pedestrian's communication terminal, communication with the pedestrian is possible. A drone dispatch type search technology that searches for the pedestrian while securing it is also required.

In addition, it is a technology to rescue a pedestrian who is in distress while walking by a companion for the pedestrian, and it is possible to dispatch the companion to the site while ensuring the safety of the companion. Dispatch-type rescue technology is also required.

In addition, it is a technology to discretely install a plurality of transmitters along a walking route in order to guide a pedestrian while walking, and is effective guidance information while reducing the number of transmitters to be installed. There is also a demand for branch point installation type guidance technology that provides pedestrians with.

[First Embodiment]

FIG. 1 conceptually shows a system diagram of the hardware configuration of a mountain trail guidance system (hereinafter, simply referred to as “system”) 10 according to the first embodiment of the present invention. The system 10 is designed to implement a pedestrian guidance method according to an embodiment of the present invention.

<About the outline of the system>

To give a schematic description, as shown in FIG. 2, this system 10 uses a user climber (an example of a “pedestrian”) as a mountain trail 14 (an example of a “walking route”) in a mountainous area 12. An example. In an example of a mountain route, it is determined that the walking condition of the climber is abnormal (whether there is a possibility of getting lost or deviating from the mountain trail 14, etc.), and the result is To warn the climber, and finally to help guide the climber along the correct walking route (in the correct direction, along the correct course), thereby preventing accidents. It has a route guidance function.

<Mountain trail guidance function>

In this system 10, in order to realize the mountain trail guidance function, a plurality of guide transmitters 30 are installed so as to be arranged discretely and in series along the mountain trail 14. The guide transmitters 30 are arranged in series at equal intervals (for example, at intervals of 10 m, 50 m, 100 m, 500 m, and 1 km). Alternatively, the plurality of guide transmitters 30 may be arranged in series at variable intervals that decrease as they approach the end point of the trail 14.

Each guide transmitter 30 may be artificially installed on the mountain trail 14, for example, a support or a sign, or a natural object growing on the mountain trail 14, for example, a natural tree or a tree. It may be attached to.

The signals from the plurality of guide transmitters 30 are sequentially received by the mountaineer's mobile terminal 90 (an example of a "user terminal") in a short-range wireless communication system as the mountaineer walks. The mobile terminal 90 can wirelessly communicate with the management server 50 operated and managed by the management center 40 installed in a remote location from the mountainous area 12.

The mobile terminal 90 is used alone or in cooperation with the management server 50 to realize the mountain climbing route guidance function, and the climber's walking route (where to walk) and walking while climbing or descending the mountain. Warn the climber (notify the climber that he may be lost and pay attention to the climber) so that both routes (in which direction to walk) do not deviate from the regular one. (Awakening, etc.) and route guidance.

Here, as a "warning", for example, a mountaineer may announce that he / she may have lost his / her way in the mountainous area 12, call attention to the mountaineer, or urge corrective action as it is. If you continue walking, you may be notified that the radio waves of the mobile terminal 90 will enter the communication range that does not reach the other mobile terminals 90. Outside the communication range, for example, there is no receivable ground base station 300 (see Fig. 2) nearby, or because there are tall trees and adjacent mountains around the climber, the climber's There is an area where the radio waves of the mobile terminal 90 are blocked.

In addition, as "route guidance (route guidance, course guidance, route guidance, etc.)", for example, the climber is provided with position information and direction information for correcting the actual walking route and course to a regular walking route and course. Doing so, for example, may visually, audibly, or tactilely inform the user of a message that "because you are lost, it is desirable to return to your current route."

In this example, when the mobile terminal 90 of the climber who is in a lost state detects that he / she is in a lost state by using the guide transmitter 30, he decides to call attention and to return to the current route. In order to encourage the climber to do so, the message may be output in text, image or voice, or the confirmation of the message by the climber may be confirmed as an operation of the "confirmation button". In this case, the climber's mobile terminal 90 may continue to display the same button until the "confirmation button" is tapped by the user.

Nevertheless, if the continuous display time of the "confirmation button" exceeds a predetermined time limit but the "confirmation button" is not tapped by the user, the mobile terminal 90 of the climber this time is the user. It is determined that the climber may have fallen into an emergency (for example, a distress), and this is transmitted to the management server 50, and each of the other climbers (accompanied persons) belonging to the same party. It is transmitted to the mobile terminal 90 all at once.

Further, the mobile terminal 90 of each mountaineer provides its positioning function (for example, a positioning function using GPS, a ground base station 300) during mountaineering, at all times, or from the time when the warning is issued to the mountaineer. The position information by the used positioning function) is acquired in a time-specific manner, and the position information is sequentially transmitted to the management server 50 in order to facilitate the search work in the event of a distress.

Upon receiving the location information, the management server 50 sequentially stores the location information in the memory 162 (see FIG. 9) in chronological order in association with the user ID / device ID of the mobile terminal 90 of each mountaineer. When a distress occurs in the mountaineer, the mountaineer's mobile terminal 90 accesses the management server 50, and the management server 50 extracts the action history of the mountaineer's victim from the memory 162 and accompanies other people. It is transmitted to the mobile terminal 90 of the person. Therefore, the management server 50 and other companions can track the location of the victim at least from the time the warning was given to the victim.

The behavior history of the victim, that is, the tracking result, is used, for example, for the search work of the victim by other companions or rescue workers. In addition, the action history of the victim is used when the management server 50 determines the flight target point of the drone 200, which will be described later.

In this system 10, in order to realize the mountain climbing road guidance function, when the mountaineer's mobile terminal 90 receives the identification signal from any of the guide transmitters 30, the mountaineer uses any of the guide transmitters 30. It is decided as a reference transmitter (start transmitter, departure point transmitter, etc.) that has been confirmed to have passed.

After determining the reference transmitter, the mobile terminal 90 refers to the mapping data (see FIG. 7), which will be described later, downloaded from the management server 50, and thereby, among the plurality of guide transmitters 30, the walking route (see FIG. 2). In, the one located next to the reference transmitter is determined as the target transmitter (forward transmitter, adjacent transmitter, target point transmitter, etc.).

Further, when the mobile terminal 90 receives the identification signal from the target transmitter before the predetermined time limit f elapses from the time when the identification signal is received from the reference transmitter, the walking state of the climber is normal (road). On the other hand, if the identification signal is not received from the target transmitter even after the predetermined time limit f has elapsed, the climber's walking state may be abnormal (may be lost). Yes).

FIG. 3 is a perspective view in which two of the plurality of guide transmitters 30 in FIG. 2 adjacent to each other are taken out and enlarged. The two guide transmitters 30 are installed at two points A and B adjacent to each other. In the example shown in FIG. 3, the point A is located at the entrance point (start point, start point) of the mountain trail 14, and the point Z is at the top point (turning point, end point, end point) of the mountain trail 14. To position.

During mountain climbing (when climbing the mountain climbing road 14) (in the walking route, ascending direction, and climbing direction during mountain climbing), point B is ahead of point A in the direction of travel, so the guide transmitter 30 at point A Is the reference transmitter, the guide transmitter 30 at point B is the target transmitter.

On the other hand, during the descent (when going down the mountain trail 14) (in the walking route, descent direction, and descent direction during the descent), the point A is ahead of the point B in the traveling direction, so that the point B When the guide transmitter 30 is the reference transmitter, the guide transmitter 30 at the point A is the target transmitter.

Further, as illustrated in FIG. 3, the distance d between the guide transmitter 30 at the point A and the guide transmitter 30 at the point B, to be exact, not the shortest distance, but the mountain trail 14 was measured along it. There is a length of time. Further, there is also an altitude difference Δh between the guide transmitter 30 at the point A and the guide transmitter 30 at the point B.

Further, as illustrated in FIG. 3, the reception area for the guide transmitter 30 at the point A and the reception area for the guide transmitter 30 at the point B do not overlap each other, so that the guide transmitters 30 of the respective guide transmitters 30 do not overlap with each other. Since the reception range is set, one mobile terminal 90 does not effectively receive the identification signal from the two guide transmitters 30 at the same time at each moment.

In FIG. 6A, in this system 10, the same mobile terminal 90 is placed next to the point before the predetermined time limit f elapses from the time when the mobile terminal 90 receives the signal from the guide transmitter 30 at the point A. A normal walking state scenario in which a signal is received from the guide transmitter 30 of B is illustrated in a graph.

On the other hand, in FIG. 6B, in this system 10, even if a predetermined time limit f elapses from the time when the mobile terminal 90 receives the signal from the guide transmitter 30 at the point A, the same mobile terminal 90 is shown. An abnormal walking state scenario in which no signal is received from the guide transmitter 30 at the adjacent point B is shown as an example in a graph.

As shown in FIG. 6B, in this system 10, even if the predetermined time limit f elapses, if the mobile terminal 90 does not receive a signal from the guide transmitter 30 at the adjacent point B, the mobile terminal 90 However, it is determined that the walking state (traveling direction, etc.) of the climber is abnormal (for example, lost), and a warning is given to the climber.

If the climber does not notice the warning, the climber's mobile terminal 90 or management server 50 may distress the climber's mobile terminal 90 for each of the other companions. Are sent all at once. Further, in order to realize the above-mentioned victim search function, the management server 50 executes the victim search mode.

FIG. 7 shows a predetermined relationship between the transmitter ID of each guide transmitter 30 and the installation position of each guide transmitter 30 on the map, and a plurality of guides along the correct walking route of the mountain trail 14. Mapping data representing the order in which the transmitters 30 are lined up and the length of the time limit f described above are conceptually represented by a table.

The mapping data is originally stored in the memory 162 of the management server 50, and when accessed from an arbitrary mobile terminal 90, the management server 50 transmits the mapping data to the mobile terminal 90, thereby. The mobile terminal 90 downloads mapping data from the management server 50 and stores it in its own memory 132 (see FIG. 5).

<About setting the time limit f>

In this system 10, the time limit f is set for each point pair consisting of two points adjacent to each other, as shown in FIG. The time limit f assumes a climber with normal athletic ability, and the average climber traverses between the two points based on the actual route d between two points adjacent to each other and the altitude difference Δh. It is preset so that it does not fall below the minimum time required for.

FIG. 8A is a graph showing an example in which the altitude gradually changes between two points A and B adjacent to each other on the mountain trail 14. FIG. 3B is a graph showing an example in which the altitude suddenly changes between these points A and B.

In this system 10, the time limit f is calculated as the product of the reference time S and the correction coefficient k. FIG. 8C is an exemplary graph showing that the length of the reference time S increases with the distance d between the two points A and B. FIG. 3D is an exemplary graph showing that the correction coefficient k increases according to the altitude difference Δh between the two points A and B.

<Companion mutual communication function>

In addition to the above-mentioned mountain trail guidance function, this system 10 supports mutual assistance by communicating with each other using each mobile terminal 90 among a plurality of climbers belonging to the same party (team, group, etc.). It has a companion mutual communication function. This companion mutual communication function also functions as a function for confirming the safety of the victim.

In this system 10, when a plurality of people climb a mountain as one party by the companion mutual communication function (mutual assistance function), if one climber falls into an emergency, information about it is given to other climbers. By sharing information with each other and sharing information with each other on the mobile terminal 90, it is possible to prevent a distress, immediately go to rescue, and even if a distress occurs, it will be possible to search immediately.

Specifically, for example, when a plurality of people climb a mountain as one party, it is found that one of the climbers has fallen into an emergency (for example, the climber's mobile terminal 90 or management server). 50 infers the existence of the emergency), and the climber's mobile terminal 90 or management server 50 automatically sends the emergency to each of the other climbers' mobile terminals 90 at the same party all at once. Wirelessly transmit information about.

In one example, the mobile terminals 90 of a plurality of climbers belonging to the same party automatically try to establish an interconnection regardless of the presence or absence of a distress or, if necessary (for example, a state in which the user does not notice). However, if there is another mobile terminal 90 whose connection is not established, it is reported to the management server 50. The management server 50 determines that a mountaineer who is a user of another mobile terminal 90 whose connection cannot be established may have fallen into an emergency, and determines that each of the other mountaineers whose connection is established may have entered an emergency. It is transmitted to the mobile terminal 90 all at once.

In another example, if the management server 50 periodically attempts to establish a connection with each mobile terminal 90 and nevertheless does not establish a connection with any of the mobile terminals 90. It is determined that the climber who should own one of the mobile terminals 90 may have fallen into an emergency, and this is simultaneously transmitted to the respective mobile terminals 90 of the other climbers.

Here, as the "emergency situation", for example, the walking route may not be corrected even if the warning is given, or the connection with a certain mobile terminal 90 may not be established. In the latter case, for example, a mountaineer may be out of the communication range, or the battery of the mountaineer's mobile terminal 90 may be insufficient. In either case, if the mountaineer is in distress, This is a case where it becomes impossible to search for the climber by relying on the mobile terminal 90, and the search may be difficult.

<Distress search function>

In addition to the above-mentioned mountain trail guidance function and companion mutual communication function, this system 10 has a victim search function for searching for the victim in the event that the climber is in distress in the mountainous area 12. This victim search function also functions as a function for confirming the safety of the victim.

In this system 10, a mountaineer transmitter 32 is attached to a mountaineer before climbing in order to realize a victim search function. The mountaineer transmitter 32 moves integrally with the mountaineer who is the wearer, and the position of the mountaineer transmitter 32 coincides with the position of the mountaineer.

In addition, the system 10 is equipped with an unmanned aerial vehicle or drone 200 to search for the victim from the sky. The drone 200 can use its own controller 202 and can be operated remotely according to an instruction from the management server 50, or can be used for autonomous navigation using the controller 202.

When the management server 50 determines that any of the climbers may have been in distress, the management server 50 determines that the representative spatial coordinate values of the mountainous area 12 on which the climber is climbing (for example, the summit, the entrance of the mountain trail 14, etc.) The latitude, longitude, and altitude of the representative point) are transmitted to the communication device 204 of the drone 200 as information indicating the flight target point, and the drone 200 is instructed to dispatch (deploy) via the controller 202.

The drone 200 includes a controller 202 and a communication device 204 connected to the controller 202. The communication device 204 is capable of wireless communication with the management server 50. The communication device 204 may function as a normal mobile phone (mobile phone) that uses the ground base station 300, or may function as a satellite phone that uses an artificial satellite.

In addition to the communication device 204, the drone 200 is equipped with an aerial mobile (movable) aerial base station (hereinafter referred to as "relay base station") 206 that replaces the fixed ground base station 300 for the mobile terminal 90. doing. The relay base station 206 receives the position information from the mobile terminal 90 within the communication range of the relay base station 206, and transmits the position information to the ground base station 300 within the communication range of the relay base station 206.

The drone 200 further has a receiver 210 capable of receiving a signal from the victim's climber transmitter 32. The controller 202 measures the intensity of the radio wave received from the mountaineer transmitter 32 by the receiver 210 every moment. The controller 202 navigates the drone 200 in a direction in which the current value of the radio field intensity measurement value increases from the previous value.

In this system 10, in order to search for a mountaineer in distress, a mobile terminal use mode for searching for the victim himself by relying on the mobile terminal 90 of the victim and a mountaineer transmitter 32 of the victim are relied on. There is a transmitter use mode that searches for the victim himself.

First, to briefly explain, in the mobile terminal use mode, a distress is made by using the positioning function and the communication function of the mobile terminal 90 on the condition that the connection between the mobile terminal 90 and the management server 50 is established. Performed to search for a person. In this search scenario, the mobile terminal 90 as an accessory of the victim is used directly for the search of the victim.

On the other hand, in the transmitter use mode, the connection between the victim's mobile terminal 90 and the management server 50 is not established, for example, the mobile terminal 90 has a short battery or the mobile terminal 90. Is located outside the communication range, and is executed to search for a victim by using the location authentication function and the transmission function of the mountaineer transmitter 32.

Specifically, in this transmitter use mode, the drone 200 is dispatched, and the intensity of the radio wave received by the receiver 210 mounted on the drone 200 from the mountaineer transmitter 32 of the victim is sequentially measured. The flight route of the drone 200 is determined so that the measured value increases over time. As a result, the search scenario of searching for the victim, or the condition that the victim's mobile terminal 90 operates normally (for example, the battery is not insufficient and the mobile terminal 90 is not broken). , A search scenario in which the mobile terminal 90 is connected to the management server 50 via the relay base station 206 mounted on the drone 200 and further via the nearest ground base station 300. It will be realized.

In the former search scenario, the mountaineer transmitter 32 as one of the equipment of the victim is directly used for the search of the victim by the drone 200. On the other hand, in the latter search scenario, the transmitter use mode is executed in order to make the above-mentioned mobile terminal use mode executable.

Specifically, in the latter search scenario, when the drone 200 is dispatched, approaches the victim, and the victim's mobile terminal 90 enters the communication range of the relay base station 206, the relay base station 206 is relayed. The function establishes a connection between the victim's mobile terminal 90 and the ground base station 300, and thus establishes a connection between the victim's mobile terminal 90 and the management server 50. In this case, the mobile terminal use mode is executed, and the victim can communicate with the management server 50. In this case, for example, the victim can talk to the operator of the telephone of the management center 40 and transmit data (messaging) via his / her mobile terminal 90.

The drone 200 also has a camera 220 that captures the ground as a still image or moving image from the sky. The camera 220 generates imaging data representing an image on the ground, and the imaging data is transmitted to the management server 50 via the communication device 204. The operator of the management center 40 can remotely monitor the state of the ground surface of the mountainous area 12 via the camera 220. As a result, the operator of the management center 40 can visually and remotely search for the victim. The operating state (on / off, etc.), shooting conditions (zoom rate, exposure, etc.) and posture (angle, etc.) of the camera 40 are remotely controlled by the management server 50 via the controller 202.

The drone 200 also has a speaker 230 that outputs sound from the sky. The speaker 230 is remotely controlled by the management server 50 via the controller 202. For example, the controller 202 drives the speaker 230 based on the voice data received from the management server 50, thereby generating and outputting the voice. As a result, the operator of the management center 40 can output voice from the sky toward the mountainous area 12 via the speaker 230.

Thanks to its voice output, the operator of the management center 40 can audibly inform the victim of the current search, the existence of the drone 200 and its current location before the victim is found. In addition, after the victim is found, it is possible to confirm the safety of the victim, give instructions on actions to be taken by the victim for rescue, and provide information on the current state of relief activities.

The drone 200 further has a shooter 240 that drops or drops the necessary items from the sky toward a target position on the ground, equipped with a parachute, if necessary. The shooter 240 is remotely controlled by the management server 50 via the controller 202. Items to be dropped include, for example, relief supplies (for example, a spare charged battery pack that can be used for the victim's mobile terminal 90, water, food, etc.) and relief by locally illuminating the vicinity of the victim. There are lighting fixtures to facilitate activities.

When dropping an item from the shooter 240, it is possible to use the speaker 230 to explain the contents of the relief activity by voice or to drop the lighting equipment together in order to draw the attention of the victim. Thanks to the lighting equipment, the victim can accurately grasp the landing point of the dropped item and can reliably capture the item.

<About guide transmitters and climber transmitters>

In FIG. 4, the guide transmitter 30 and the mountaineer transmitter 32 shown in FIG. 2 having a common configuration are shown in a functional block diagram. Since the guide transmitter 30 and the mountaineer transmitter 32 have a common configuration, the common configuration will be typically described below only for the guide transmitter 30.

As shown in FIG. 4, each guide transmitter 30 transmits a unique signal, and the unique signal represents a unique transmitter ID. Since it is known at which position of the mountain trail 14 each guide transmitter 30 is installed, the installation position, that is, the spatial coordinate value (x, y, z) is assigned to the transmitter ID in advance. ..

First, conceptually, the guide transmitter 30 is a non-contact type or contact (proximity) type communication device that locally transmits an identification signal capable of identifying a unique transmitter ID.

Next, to explain the operating method, the guide transmitter 30 actively, locally, and permanently uses a unique identification signal without requiring an external trigger signal as long as the power supply is not insufficient. send.

The guide transmitter 30 is generally known as a beacon device that transmits a beacon signal as an identification signal, a radio beacon, or the like. In one example, the guide transmitter 30 generates an identification signal representing the corresponding transmitter ID by modulating the original signal, and the generated identification signal is used as an IR signal, a Bluetooth (registered trademark) signal, or the like. It is locally transmitted as an NFC (Near Field Communication) signal.

Next, to explain the hardware configuration with reference to FIG. 4, the guide transmitter 30 is mainly composed of a computer 104 having a processor 100 and a memory 102 for storing a plurality of applications executed by the processor 100. ing.

The guide transmitter 30 further has a replaceable disposable battery 106 as a power source. Instead of the battery 106, a rechargeable battery can be adopted, or a commercial power source or a solar cell as an external power source can be adopted.

When a solar cell is used as an external power source, the surplus electric energy generated by the solar cell is stored in the battery during the daytime, and the battery energy is taken out from the battery at night to use the guide transmitter 30. It may be activated.

The guide transmitter 30 further has a transmitter 108 that generates and transmits an identification signal. The transmitting unit 108 is operated by the battery 106 and controlled by the controller 110. The controller 110 is controlled by the computer 100.

To explain the software configuration of the guide transmitter 30, the processor 100 outputs a signal for modulating the original signal (for example, a carrier signal) to the controller 110 so that the transmitter ID is reflected. The controller 110 controls the transmission unit 108, and as a result, the transmission unit 108 generates an identification signal to be transmitted this time. After that, the generated identification signal is transmitted from the transmission unit 108.

<About mobile terminals>

The mobile terminal 90 of the climber (user) is a device carried by the user and having a wireless communication function, for example, a mobile phone, a smartphone, a laptop computer, a tablet computer, a PDA, or the like. The mobile terminal 90 is an example of a user's communication terminal.

Next, to explain the hardware configuration of the mobile terminal 90 with reference to FIG. 5, the mobile terminal 90 is a memory that stores a processor 130 and a plurality of programs (also referred to as “applications”) executed by the processor 130. It is mainly composed of a computer 134 having 132.

The mobile terminal 90 further generates a display unit (for example, a liquid crystal display) 136 for displaying information, a receiving unit 138 for receiving signals from the guide transmitter 30 and the management server 50, and generates a signal to generate the signal. It has a transmission unit 140 for transmitting to the management server 50. Here, the receiving unit 138 is also a part that senses the identification signal from the guide transmitter 30.

The mobile terminal 90 further has an input unit 150 for inputting data and commands from the user. The input unit 150 has, for example, an operation unit that can be operated by a user in order to input desired information (for example, a command, data, etc.) into the mobile terminal 90. The operation unit includes a touch screen that displays a user-operable icon (for example, a virtual button), a physical operation unit that can be operated by the user (for example, a keyboard, keypad, button, etc.), and voice. There are microphones that detect, but they are not limited to these.

The mobile terminal 90 further has a GPS (satellite positioning system) receiver 152. As is well known, the GPS receiver 152 receives a plurality of GPS signals from a plurality of GPS satellites, and based on the GPS signals, determines the position (latitude, longitude and altitude) of the GPS receiver 152 on the earth. Measure by triangulation.

The mobile terminal 90 further includes an acceleration sensor 154 that detects its own acceleration. Since the acceleration sensor 154 is mounted on the mobile terminal 90, it vibrates integrally with the mobile terminal 90, and as a result, the acceleration acting on the acceleration sensor 154 itself is applied to the mobile terminal 90 and the user carrying it. It is detected as equivalent to the acceleration acting on.

Here, to explain one function of the user's mobile terminal 90 in association with the guide transmitter 30, the mobile terminal 90 is in a state of receiving an identification signal from the guide transmitter 30 and is a computer of the mobile terminal 90. When a program pre-installed in, that is, a dedicated application for guide transmitter processing (hereinafter referred to as "transmitter application") is started (logged in), the received identification signal is demolished and the received identification signal is demoted. Decodes the transmitter ID.

Further, when the mobile terminal 90 starts the transmitter application in a state of receiving the identification signal from the guide transmitter 30, the mobile terminal 90 is based on the received identification signal (for example, the strength of the identification signal). It also measures the distance between the position of the guide transmitter 30 when the identification signal is transmitted and the position of the mobile terminal 90 when the identification signal is received.

That is, the mobile terminal 90 acquires both the transmitter ID unique to the guide transmitter 30 and the distance to the guide transmitter 30 at that time based on the identification signal received from the guide transmitter 30. It has become.

<Receiver range of transmitter>

Apparently, two types of reception areas are assigned to the guide transmitter 30. They are a receivable area and an effective reception area (hereinafter, also referred to as "reception range" or "reception area").

All of these areas are generally defined by a single sphere centered on the location of the guide transmitter 30. Some examples of service areas are shown in FIG.

The receivable area of the guide transmitter 30 has a maximum reception radius (for example, about 50 m), whereas the effective reception area has an effective reception radius (for example, an arbitrary value within a range of 0 m to about 50 m). Have. While the maximum reception radius is an invariant value, the effective reception radius is a variable value that can be set at any time by the mobile terminal 90, as will be described later.

The receivable area is an area where the identification signal from the guide transmitter 30 can reach when the power supply of the guide transmitter 30 is normal, that is, as long as it exists in the area, the mobile terminal 90 has the identification signal. Means the area where you can receive.

On the other hand, the effective reception area has an effective reception radius smaller than the maximum reception radius of the receivable area. While the maximum reception radius cannot be arbitrarily set, the effective reception radius can be arbitrarily set by software in the mobile terminal 90.

That is, it can be said that the maximum reception radius means the reception limit determined by the hardware, while the effective reception radius means the reception limit determined by the software.

As described above, the mobile terminal 90 measures the distance to the guide transmitter 30 based on the strength of the identification signal received by the mobile terminal 90. The distance measurement may or may not exceed the effective reception radius. Then, when the distance measurement value does not exceed the reception effective radius, it means that the mobile terminal 90 exists in the effective reception area, whereas when the distance measurement value exceeds the reception effective radius, the mobile terminal 90 Is present in the receivable area but not in the effective receivable area.

In the present embodiment, the reception range of the guide transmitter 30 is set to be, for example, a spherical region having a radius of about 0 m-5 m. That is, the effective reception radius used in the mobile terminal 90 is set to a fixed value within about 0 m-5 m. The reception effective radius may be set so that, for example, the reception area of each guide transmitter 30 covers the entire width of the mountain trail 14 where each guide transmitter 30 is installed.

<About the management server>

Next, to explain the hardware configuration of the management server 50, FIG. 9 shows the management server 50 as a functional block diagram. The management server 50 is mainly composed of a computer 164 having a processor 160 and a memory 162 for storing a plurality of applications executed by the processor 160.

The management server 50 further includes a display unit (for example, a liquid crystal display) 166 that displays information, a reception unit 168 that receives a signal from the mobile terminal 90, and generates a signal to transmit the signal to the mobile terminal 90. It has a transmission unit 170 and a clock 172. The management server 50 does not directly receive from the transmitter 30, but substantially via the mobile terminal 90.

<Software configuration of mountain trail guidance system>

In FIG. 10, a plurality of programs for explaining the software configuration of the system 10 are conceptually represented by a flowchart. These programs include a mountain climbing route guidance application (steps S101-S122) as a program executed on the mobile terminal 90 of each mountaineer, and a program (steps S151-S158) executed on the management server 50.

When the mountaineering road guidance application is started on the mobile terminal 90 of each mountaineer prior to climbing the mountaineering road 14, first, in step S101, a login request to the management server 50 is made by the user's operation, and this time. The personal information of the user who is a mountaineer is input to the mobile terminal 90. The personal information of the climber this time includes, for example, the user ID of the climber, the name and address of the user, the telephone number or e-mail address of each mobile terminal 90 of another companion, and the like. The login request and personal information are transmitted to the management server 50, and then received by the management server 50 in step S151.

Next, in step S102, the mountain trail identification information for identifying the current mountain trail 14 (for example, the name or ID of the mountain trail 14, the name of the mountainous area 12 where the mountain trail 14 exists, or The ID) is input to the mobile terminal 90, the mountain trail identification information is transmitted to the management server 50, and then received by the management server 50 in step S151.

Subsequently, in step S152, the management server 50 registers the received personal information and the mountain trail identification information in the memory 162. After that, in step S153, the management server 50 uses the mountain trail 14 represented by the mountain trail identification information received from the mobile terminal 90 this time among the plurality of mapping data (see FIG. 7) stored in the memory 162. Is read from the memory 162 and transmitted to the mobile terminal 90 this time.

In response to this, the mobile terminal 90 downloads the mapping data corresponding to the mountain trail 14 from the management server 50 in step S103. The downloaded mapping data is stored in the memory 132 in association with the mountain trail 14 and the date.

Subsequently, in step S104, the mobile terminal 90 displays a page as shown in FIG. 11A on the screen, and the user should take action on the mountain trail 14 this time on the screen. Enter the data to distinguish between the mountain and the mountain.

In a typical example, first (for example, at the start point A of the mountain trail 14), as shown in FIG. 11A, the user operates and responds to a button representing "mountain climbing", and the mobile terminal 90 In, the above-mentioned mountain trail guidance mode is activated on the condition that the mountain is climbing and not descending.

After that, when the user safely arrives at the end point Z of the mountain trail 14 and tries to start descending the mountain, the user operates a button indicating "reset" as shown in FIG. 11A. Then, the button representing "downhill" is operated. In response to this, the above-mentioned mountain trail guidance mode on the mobile terminal 90 is activated from the first step on the condition that the mountain is descending and not climbing.

Subsequently, in step S105, the mobile terminal 90 attempts to receive the identification signal from any of the guide transmitters 30. After that, in step S106, the mobile terminal 90 determines whether or not the identification signal is effectively received from any of the guide transmitters 30. If the identification signal is not effectively received (effective reception fails), the determination becomes NO, and the process returns to step S105. On the other hand, when the identification signal is effectively received (effective reception is successful), the determination in step S106 is YES.

The mobile terminal 90 effectively received the identification signal from any of the guide transmitters 30 (the one closest to the user's current position among the plurality of guide transmitters 30) (successful effective reception). In the case, subsequently, in step S107, the mobile terminal 90 is a map showing the mountain trail 14 covering the current position on the screen, and the installation position of any of the received guide transmitters 30. And the current position measured using the built-in GPS described above are displayed in an overlay state.

When the mobile terminal 90 is also equipped with a directional sensor, the user holds the mobile terminal 90 horizontally and determines the orientation of the mobile terminal 90 in the direction of the map displayed on the screen and the mobile terminal 90. The directions are adjusted so that they match each other, which makes it possible to visually guide the climber's future direction of travel using a screen.

After that, in step S108, the mobile terminal 90 determines the guide transmitter 30 received this time as the above-mentioned reference transmitter.

Subsequently, in step S109, the mobile terminal 90 determines whether or not it is downhill this time. If it is not downhill but climbing, the determination is NO, and in step S110, the guide transmitter 30 received this time when viewed in the climbing direction of the mountain trail 14 among the plurality of guide transmitters 30. Another guide transmitter 30 located immediately next to the guide transmitter 30 is determined as the target transmitter described above.

Specifically, in the example shown in FIG. 2, when the reference transmitter is the guide transmitter 30 located at the point E (fifth counting from the starting point A), the reference transmitter is the point F (counting from the starting point A). The guide transmitter 30 located at 6th) is determined as the target transmitter.

On the other hand, this time, if the mountain is not climbing but descending, the determination in step S109 is YES, and in step S111, when viewed in the downward direction of the mountain trail 14 among the plurality of guide transmitters 30. , Another guide transmitter 30 located immediately next to the guide transmitter 30 received this time is determined as the target transmitter described above.

Specifically, in the example shown in FIG. 2, when the reference transmitter is the guide transmitter 30 located at the point E (fifth counting from the starting point A), the reference transmitter is the point D (counting from the starting point A). The guide transmitter 30 located at the fourth) is determined as the target transmitter.

In either case, the mobile terminal 90 then attempts to receive the identification signal from the current target transmitter in step S112. After that, in step S113, the mobile terminal 90 determines whether or not the identification signal is effectively received from the target transmitter this time. If the identification signal is not effectively received (effective reception fails), the determination becomes NO, and the process proceeds to step S115.

In step S115, the mobile terminal 90 determines whether or not the elapsed time from the first execution start time of step S112 exceeds the time limit f. If it does not exceed, the determination is YES, and the process returns to step S112.

On the other hand, when the mobile terminal 90 effectively receives the identification signal from the target transmitter (successfully received), the determination in step S113 is YES.

Subsequently, in step S114, the mobile terminal 90 displays a map near the current position, the installed position of the received target transmitter, and the measured current position on the screen in the same manner as in step S107 described above. Display in overlay state. After that, the process returns to step S108, and the target transmitter this time is determined as the next reference transmitter this time.

On the other hand, if the mobile terminal 90 does not effectively receive the identification signal from the target transmitter even if the elapsed time from the execution start time of step S112 exceeds the time limit f, the determination in step S115 is NO.

After that, in step S116, the mobile terminal 90 determines that the walking state of the climber this time is abnormal. In this abnormality judgment, for example, the climber may not be able to reach the target transmitter this time in the section between the reference transmitter this time and the target transmitter this time, and may be lost. It means a judgment to that effect.

Subsequently, in step S117, the mobile terminal 90 gives a visual warning to the climber this time, as illustrated in FIG. 11B. In one example, the mobile terminal 90 has a message saying "You may have lost your way. It is recommended to turn back the route" and to confirm that the climber has read the message. The confirmation buttons to be operated are displayed on the screen in association with each other.

After that, the mobile terminal 90 measures the current position in step S118 by using the built-in GPS described above. Subsequently, in step S119, the mobile terminal 90 transmits the position information representing the positioning result to the management server 50 in association with the user ID and the current time.

On the other hand, in step S154, the management server 50 receives the location information from the mobile terminal 90 this time in association with the user ID and the current time, and subsequently, in step S155, the location information is stored in the memory 162 with the user ID and the user ID. Save in association with the current time. As a result, the action history of the climber this time is stored in the memory 162 in chronological order in association with the time, and the information becomes useful information when tracking the climber.

The mobile terminal 90 then determines in step S120 whether or not the confirmation button has been operated by the user, as illustrated in FIG. 11B. If the confirmation button is not operated, the determination is NO, and the mobile terminal 90 determines whether or not the elapsed time from the first execution start time of step S120 exceeds the predetermined time limit g in step S121. Is determined. If it does not exceed, the determination is YES, and the process returns to step S117. Eventually, when the elapsed time exceeds the time limit g, the determination in step S121 becomes NO.

After that, in step S122, the mobile terminal 90 determines that the climber this time is a victim, and transmits the above-mentioned request for the victim search mode for searching for the victim to the management server 50. Subsequently, in step S123, the mobile terminal 90 sends a message to the effect that "contacting the companion" and a message to the effect that "requesting help" as illustrated in FIG. 11 (c). Display on the screen.

On the other hand, the management server 50 receives the request for the victim search mode from the mobile terminal 90 this time in step S156, and subsequently, in step S157, another climber accompanying the climber this time. Although it is registered in the memory 162 of the management server 50, a message for notifying that the climber may have been in distress is transmitted all at once to each mobile terminal 90.

Specifically, for this companion broadcast service, the management server is associated with each of one or more companions (for example, members of a party climbing the same mountain path 14) for this climber. In the memory 162 of 50, personal information, that is, for example, name, address, age, gender, physical condition data (for example, health data) and athletic ability (for example, years of sports experience), and contact information, that is, for example, The telephone number, e-mail address, and IP address of each companion's mobile terminal 90 are registered so as to construct the companion database.

After that, in step S158, the management server 50 dispatches the drone 200 with the current mountain trail 14 as the arrival target point. As described above, the drone 200 searches for the position of the climber by relying on the radio wave received from the climber transmitter 32 mounted on the climber this time. As a result, the above-mentioned victim search function is realized.

As is clear from the above explanation, according to the present embodiment, it is judged whether or not the climber who may be in a psychologically panic state has lost his or her way and whether or not there is a risk of distress. , It is not necessary to select the action content to avoid the distress and to judge whether or not the person was really in distress. As a result, according to the present embodiment, it is possible for a mountaineer to accurately know whether or not he / she has lost his / her way before he / she is in distress, and whether or not he / she is at risk of distress. In some cases, it becomes possible to accurately know the actions to avoid distress.

In the present embodiment, it is possible to consider that the portion of the computer 134 of the mobile terminal 90 that executes steps S105, S106, and S108 in FIG. 10 constitutes an example of the reference transmitter determination unit. It can be considered that the portion of the computer 134 of the mobile terminal 90 that executes steps S109-S111 in the figure constitutes an example of the target transmitter determination unit, and the computer 134 of the mobile terminal 90. It can be considered that the portion for executing steps S115 and S116 in the figure constitutes an example of the walking state determination unit, and among the computers 134 of the mobile terminal 90, step S117 in the figure is executed. It is possible to think that the portion constitutes an example of the warning portion.

In addition, in the present embodiment, both the first feature unit that functions as the reference transmitter determination unit and the second feature unit that functions as the target transmitter determination unit function as the walking state determination unit. The three feature parts are also mounted on the computer 134 of the same mobile terminal 90, but instead, the present invention may be implemented in such a manner that all the three feature parts are mounted on the computer 164 of the management server 50. Alternatively, the present invention may be implemented in such a manner that a part of these three feature parts is mounted on the computer 164 of the management server 50.

Further, in the present embodiment, the mobile terminal 90 is from the target transmitter on the premise that the mountaineer does not slide down from the mountain trail 14 (the mountaineer does not deviate laterally from the mountain trail 14). If the signal cannot be received within the time limit f, it is determined that the climber may be lost.

On the other hand, in the present invention, when the mobile terminal 90 cannot receive the signal from the target transmitter within the time limit f, the acceleration sensor 154 of the mobile terminal 90 is used to accelerate the mobile terminal 90, that is, the climber. Acceleration is measured, and if the absolute value of the measured value exceeds a predetermined value, it is determined that the climber may have deviated from the mountain path 14 and slipped down in the vicinity of the reference transmitter. It may be carried out in an embodiment. Here, "the possibility that the climber slipped off the mountain trail 14" is an example of the above-mentioned "abnormal walking condition".

[Second Embodiment]

Next, the victim relief system 10 according to the second embodiment of the present invention will be described in detail with reference to the drawings, but the elements common to the first embodiment described above will be described in the same name or reference numerals. By quoting using, the duplicate explanation is omitted and only the different elements are explained in detail. The victim relief system 10 is designed to implement a victim relief method according to an embodiment of the present invention.

As described above, in the first embodiment, as shown in FIG. 10, in step S156, the management server 50 is set to the victim search mode from the climber's mobile terminal 90 (an example of the “user terminal”). When the request is received, in step S157, other climbers accompanying the climber this time and registered in the memory 162 of the management server 50, but each mobile terminal 90 (“accompanying terminal”) In one example), a message is sent all at once to inform that the climber may have been in distress. The mobile terminal 90 of each companion is structurally common to the mobile terminal 90 of the climber.

On the other hand, in the present embodiment, the management server 50 unconditionally and simultaneously sends the message, that is, the climber, that is, the victim, to all of the plurality of companions registered in the memory 162. Rather than sending a message to search for and request help, send those companions (multiple candidate rescuers) to the location of the victim, but physically extend to the companion. The risk is narrowed down to those that do not exceed the reference value, and the message is sent only to each companion, that is, each rescuer (final rescuer) selected in this way.

Various methods can be adopted to narrow down the number of candidate rescuers to a smaller number of final rescuers.

In the example shown in FIG. 12, when the management server 50 dispatches a plurality of types of personal risks of each companion (when the companion is dispatched to the location of the victim) from each mobile terminal 90 of the plurality of companions. The accident risk to the companion) is received from the mobile terminal 90 of each companion.

These personal risks include the distance that the victim must walk to reach the victim's location (presumed location) (the longer the distance, the more the companion's accident risk during rescue (eg, injury risk, death). In order to measure (high risk, etc.)), the current position of each companion is the three-dimensional position (latitude x, mild y, altitude z) measured by the GPS of the mobile terminal 90 of each companion. There is geographic information to represent (an example of "accompanying information").

Another personal risk is to consider the local weather conditions at each companion's location (another example of "accompanying information") to determine whether or not to request help from each companion. There is a temperature measured by the temperature sensor of the companion's mobile terminal 90 (the lower the temperature, the higher the risk of the companion's accident at the time of rescue).

Yet another personal risk is determining whether or not to request help from each companion, taking into account different local weather conditions at each companion's location (another example of "accompanying information"). Therefore, there is the illuminance measured by the illuminance sensor of the mobile terminal 90 of each companion (the darker the brightness of the outside world, the higher the risk of the companion's accident at the time of rescue).

Yet another personal risk is to determine whether or not to request help from each companion in light of the local geographical conditions at each companion's location (another example of "accompanying information"). In addition, there is an altitude (z) measured by the GPS of the mobile terminal 90 of each companion (the higher the altitude, the lower the atmospheric pressure and the lower the oxygen concentration, so the risk of the companion's accident at the time of rescue is high).

As yet another personal risk, the physical condition data of each companion's mobile terminal 90 (“accompanying information”” is used to determine whether or not to request help from each companion in consideration of the physical condition of each companion. Yet another example of) that is entered by the user (eg, a gradual level of physical condition such as good, normal, or bad), for example, the lower the physical condition level, the more the companion at the time of rescue. There is a high risk of accidents).

As yet another personal risk, in order to determine whether or not to request help from each companion in consideration of the physical condition of each companion, the motor ability data of each companion's mobile terminal 90 (“accompanying information”). (For example, the number of years of experience of the person in the sport up to the day of the sport), which is input by the user (for example, the closer the number of years of experience is to 0, the higher the risk of accident of the companion at the time of rescue). Is high).

In the example shown in FIG. 12, the management server 50 further determines a plurality of types of environmental risks of each companion (the companion is the victim) based on the meteorological characteristics of the location of the victim (an example of “environmental information”). The accident risk to the companion when dispatched to the location) is received from the weather server 400 (an example of "environmental server").

As for the environmental risk, the weather risk at the location of the victim (estimated as the position measured by the GPS of the victim's mobile terminal 90) (the worse the weather (rainy weather, snowfall, etc.)), the more the companion at the time of rescue There is a high risk of accidents).

Another environmental risk is the temperature risk at the location of the victim (the greater the temperature outside the proper range, the higher the risk of a companion's accident during rescue).

Yet another environmental risk is the wind speed risk at the location of the victim (the higher the wind speed, the higher the risk of a companion's accident during rescue).

In the example shown in FIG. 12, the management server 50 further applies a plurality of types of environmental risks of each companion to the terrain server 500 (another example of "environmental information") based on the terrain characteristics of the location of the victim (another example of "environmental information"). Receive from another example of "environment server").

Environmental risks include terrain risk at the location of the victim (for example, the steeper the slope, the higher the risk of a companion's accident during rescue).

Another environmental risk is the surface risk at the location of the victim (for example, the more likely a natural disaster such as a landslide, avalanche, or debris flow to occur in a mountainous area, the higher the risk of a companion's accident during rescue). is there.

In the example shown in FIG. 12, the management server 50 determines the position of the companion (more accurately, the distance D (Distance) between the companion and the victim) and the location of the companion for each companion. Temperature (Temperature) T (Temperature), illuminance L (Lightness) at the companion's location, altitude H (Height) at the companion's location, companion's physical condition C (Condition), and companion's motor ability M From (Motor Skill), calculate the total personal risk F as follows.

F = D · k ₁ + T · k ₂ + L · k ₃ + H · k ₄ + C · k ₅ + M · k ₆
k ₁ , k ₂ , k ₃ , k ₄ , k ₅ , k ₆ : Weight coefficient multiplied by each risk variable (default value)

The larger the calculated value of the total personal risk F, the higher the risk of accident of the companion at the time of relief.

In the example shown in FIG. 12, the management server 50 determines the weather risk M ₁ , the temperature risk M ₂ , the wind speed risk M ₃ , the terrain risk S _1, and the surface risk for each victim at the location of the victim. from S ₂ Prefecture, as shown in the following equation to calculate the overall environmental risk G.

G = M ₁・ k ₇ + M ₂・ k ₈ + M ₃・ k ₉ + S ₁・ k ₁₀ + S ₂・ k ₁₁
k ₇ , k ₈ , k ₉ , k ₁₀ , k ₁₁ : Weighting factor (default value) multiplied by each risk variable

The larger the calculated value of the total environmental risk G, the higher the accident risk of the companion at the time of relief.

FIG. 13 shows the communication performed between the mobile terminals 90 of a plurality of companions, the management server 50, the weather server 400, and the terrain server 500 in order to realize the above-mentioned simultaneous transmission service of the companions. The programs executed by the processors of each component are represented in conceptual sequences.

As shown in FIG. 10, when the management server 50 receives the request for the victim search mode from the mobile terminal 90 this time in step S156, the management server 50 accompanies each of them in step S1351 as shown in FIG. A request for requesting an individual risk from a person (each candidate rescuer) is simultaneously transmitted to all of a plurality of mobile terminals 90 of a plurality of companions.

When the mobile terminal 90 of each companion receives the request in step S1301, the current position of each mobile terminal 90 is measured as the location of each companion by the GPS in step S1302.

Subsequently, in step S1303, the mobile terminal 90 of each companion detects the temperature (air temperature) T at the location of each companion by the temperature sensor of the mobile terminal 90 of each companion. Further, the illuminance sensor of the mobile terminal 90 of each companion detects the illuminance L at the location of each companion. Further, the GPS of the mobile terminal 90 of each companion detects the altitude H of the location of each companion.

After that, in step S1304, the mobile terminal 90 of each companion inputs the plurality of detection values T, L, H described above at the level of the physical condition C of the mobile terminal 90 of each companion by the user ( For example, the higher the degree of fatigue of the companion, the higher the level) and the level of the motor ability M of each companion's mobile terminal 90, which is input by the user (for example, the lower the companion's motor ability, the higher the level). (Higher level) and each of them is transmitted to the management server 50 as an individual risk.

On the other hand, in step S1352, the management server 50 receives the individual risks from the mobile terminal 90 of each companion, and subsequently, in step S1353, the received individual risks are associated with each companion and stored in the memory. Store in 162.

Subsequently, in step S1354, the management server 50 estimates the current position last received from the mobile terminal 90 of the victim who is the mountaineer as the location of the victim and reads it from the memory 162. The location is set as a relief point and registered in memory 162.

After that, in step S1355, the management server 50 transmits a request for requesting a plurality of environmental risks to the weather server 400 and the terrain server 500, respectively, together with the set relief point.

Each of the meteorological server 400 and the terrain server 500 receives the request in step S1371, and subsequently covers the rescue point in each of the meteorological database of the meteorological server 400 and the database of the terrain server 500 in step S1372. Search for environmental risks for certain areas.

After that, each of the meteorological server 400 and the terrain server 500 transmits the searched plurality of environmental risks to the management server 50 in step S1373.

On the other hand, the management server 50 calculates the total environmental risk G for the plurality of received environmental risks in step S1357 as described above.

Subsequently, in step S1358, the management server 50 determines whether or not the calculated value of the total environmental risk G is equal to or less than the preset upper limit value (an example of the "second reference value"), that is, the rescuer. Determine if the accident risk is low. If the calculated value is equal to or less than the upper limit value, the determination is YES, and in step S159, rescue by any of the companions is permitted, but if the calculated value is higher than the upper limit value, step S1358. The determination is NO, for example, the process returns to step S1351 to wait for the environmental risk to improve for the same relief point, or to determine whether or not to rescue another relief point.

After executing step S1359, the management server 50 calculates the total individual risk F from the received plurality of individual risks for each candidate rescuer (each accompanying person) in step S1360. After that, in step S1361, the management server 50 sets the calculated total personal risk F of the plurality of candidate rescuers to be equal to or less than the preset reference point (an example of the "first reference value"). Select each as the ultimate rescuer.

Subsequently, in step S1362, the management server 50 sends a message to the mobile terminal 90 of each selected rescuer to request the search and rescue of the victim, the name, estimated location, and physical of the victim. Send with features and clothing features.

On the other hand, in step S1306, the mobile terminal 90 of each rescuer displays the received message on the screen (or outputs it by voice), and further displays a confirmation button on the screen. After that, in step S1307, the corresponding rescuer operates the confirmation button on the mobile terminal 90 of each rescuer, provided that the confirmation button is operated by the user of the mobile terminal 90, that is, the rescuer. As a result, the intention of accepting the rescue request is transmitted to the management server 50.

On the other hand, in step S1363, the management server 50 receives the information that the confirmation button has been operated from the mobile terminal 90 of any of the rescuers, identifies the rescuer who has accepted the rescue request, and has memory 162. Register with.

However, if the management server 50 cannot receive the information that the confirmation button has been operated from any of the rescuer's mobile terminals 90 even after the time limit has elapsed, the management server 50 sets the reference point in step S1364. The current value is updated to decrease by a predetermined amount, and then the process returns to step S1361. Thereby, the next execution of this step S1361 expands the range of the plurality of rescuers who consult the rescue request, thereby increasing the probability of finding a rescuer who accepts the rescue request.

As is clear from the above description, in the present embodiment, for convenience of explanation, the portion of the climber's mobile terminal 90 that executes steps S105-S117 and S120-S122 in FIG. 10 is the "distress determination unit". It is possible to think that it constitutes an example of. An example of the "distress determination unit" is to determine a victim using a plurality of guide transmitters 30 as external devices of the mobile terminal 90, but another example of the "distress determination unit" is , The above-mentioned acceleration sensor 154 (an example of a motion sensor for measuring the behavior of a mountaineer) is used to determine the victim as described above.

Further, in the present embodiment, for convenience of explanation, the portion of the management server 50 that executes steps S1352 and S1360 in FIG. 13 constitutes an example of the “individual risk calculation unit”, and the management server 50. , The part that executes step S1354-S1357 in the figure constitutes an example of the "environmental risk calculation unit", and the part that executes step S1359 in the figure is the "rescue permission unit". An example is configured, and the portion of the management server 50 that executes steps S1361 and S1364 in the figure constitutes an example of the “rescue person selection unit”, and the management server 50 in the figure. It is possible to think that the part that executes step S1362 constitutes an example of the “relief request unit”.

[Third Embodiment]

Next, the mountain trail guidance system 10 according to the exemplary third embodiment of the present invention will be described in detail with reference to the drawings, but the elements common to the first embodiment described above will have the same name or reference numeral. By quoting using, the duplicate explanation is omitted and only the different elements are explained in detail. The system 10 is designed to implement a pedestrian guidance method according to an embodiment of the present invention.

As described above, in the first embodiment, as shown in FIG. 2, a plurality of guide transmitters 30 are located along the mountain trail 14 from the starting point (starting point) to the target point (ending point). It is installed regardless of. After that, it is determined that the climber may have lost his way because the time required for the climber to walk from one guide transmitter 30 to the next guide transmitter 30 exceeds the time limit. To.

On the other hand, in general, the cause of the possibility that a mountaineer gets lost on a mountain trail is not a part of one of the mountain trails 14 but a part having a branch point. Rather than installing the transmitter 30 as a guide transmitter all over the same mountain trail 14, the climber is in the path only at the branch point (or among a plurality of branch points, statistically or empirically). If the transmitter 30 is installed as a branch point transmitter only at a branch point where there is a high possibility of getting lost), the total number of transmitters 30 to be installed can be reduced, which is advantageous in terms of cost and man-hours.

In view of this fact, in the present embodiment, as illustrated in FIG. 14, the branch point transmitter 30 is installed only at a plurality of branch points in the mountain trail 14.

Further, in the present embodiment, when the mountaineer's mobile terminal 90 starts receiving from any of the branch point transmitters 30, in response, the mountaineering path 14 is displayed on the screen as illustrated in FIG. Of these, the map image showing only the area near the branch point this time is displayed together with the mark showing the current position of the climber, the mark showing the correct course, and the branch point name (in addition, climbing information useful for the climber). The operation of being done is started.

After that, when the mobile terminal 90 stops receiving the signal from the same branch point transmitter 30, the map image displayed up to that point disappears from the screen.

Further, in the present embodiment, as illustrated in FIG. 16, each mountain trail is stored in the memory 162 of the management server 50 for each destination, that is, for each of the plurality of mountain trails 14 (for example, for each mountain area). A map database representing map data for all 14 is constructed. However, in the present embodiment, the map database is constructed so as to be effective only when the climber climbs the mountain trail 14 toward the summit for convenience of explanation.

Therefore, when any of the destinations is specified, one map data is specified.

Each map data is configured as a collection of a plurality of partial map data, and in each map data, each partial map data and a branch point ID representing one branch point included in the partial map data are associated with each other. ..

As illustrated in FIG. 15, each partial map data is correct as determined by the relationship between at least three routes intersecting at the junction and the trail 14 at the junction and the destination designated by the climber. It is configured to include a mark that associates the course with its position.

Although not shown, the memory 162 of the management server 50 further represents a transmitter ID represented by an identification signal transmitted by each branch point transmitter 30 and a branch point in which each branch point transmitter 30 is installed. A predetermined relationship with the branch point ID is also stored.

Therefore, when the mobile terminal 90 receives the signal from any of the branch point transmitters 30, one transmitter ID is specified, one branch point ID is specified, and one partial map data is obtained. Be identified.

FIG. 17 shows the communication performed between the plurality of branch point transmitters 30, the climber's mobile terminal 90, and the management server 50 in order to realize the above-mentioned branch point guidance service, and the processors of each component. Each of the programs executed by is represented by a conceptual sequence. In the mobile terminal 90, a mountaineer guidance application is installed in the memory 132 as a corresponding program.

FIG. 18A is a perspective view showing an example of a climber walking and passing through a branch point while the system 10 is operating. FIG. 3B is a time chart showing a time chart of a state in which the mobile terminal 90 receives one of the branch point transmitters 30 in the walking example of FIG. FIG. 3C is a time chart showing the temporal change of the display state on the screen of the climber's mobile terminal 90 in the walking example of FIG.

As shown in FIG. 17, when the climber guidance application is activated on the mobile terminal 90, the climber inputs a destination to his / her mobile terminal 90 in step S1701. Subsequently, in step S1702, the mobile terminal 90 transmits a request for requesting the map data corresponding to the input destination to the management server 50 together with the destination.

On the other hand, the management server 50 receives the request in step S1731, and subsequently, the management server 50 uses the destination received from the mobile terminal 90 as a key in the map database in step S1732 to correspond to the request. Search for map data. After that, in step S1733, the management server 50 transmits the searched current map data (a collection of a plurality of partial map data) to the climber's mobile terminal 90.

On the other hand, the mountaineer's mobile terminal 90 receives the map data of this time from the management server 50 in step S1703, and stores the map data in the memory 132 of the mobile terminal 90 in association with the destination of this time.

Subsequently, the climber's mobile terminal 90 attempts to receive a signal from any of the branch point transmitters 30 in step S1704. After that, in step S1705, the climber's mobile terminal 90 determines whether or not the mobile terminal 90 effectively receives the signal from any branch point transmitter 30, that is, the mobile terminal 90 transmits one of the branch points. It is determined whether or not the device 30 exists in the reception area (effective reception area) of the machine 30. If the reception is not valid, the determination becomes NO, and the process returns to step S1704. However, if the reception starts effectively, the determination changes to YES.

In the example of FIG. 18B, when the determination in step S1705 is YES at the timing shown at time t1, the climber's mobile terminal 90 acquires the current transmitter ID from the received signal in step S1706. Subsequently, in step S1707, the acquired transmitter ID is converted into a branch point ID according to the above relationship.

After that, in step S1708, the climber's mobile terminal 90 selects the data corresponding to the current branch point ID from the plurality of partial map data stored in the memory 132 of the mobile terminal 90, and the current partial map. Read data from memory 132. Subsequently, in step S1709, the climber's mobile terminal 90 displays the read partial map data on the screen at the timing shown at time t3 in the example of FIG. 18 (c), as illustrated in FIG. Start to do.

Subsequently, the climber's mobile terminal 90 attempts to receive a signal from any of the branch point transmitters 30 in step S1710. After that, in step S1711, the climber's mobile terminal 90 determines whether or not the mobile terminal 90 effectively receives the signal from any of the branch point transmitters 30, that is, the mobile terminal 90 transmits one of the branch points. It is determined whether or not the device 30 exists in the reception area (effective reception area) of the machine 30.

When the climber's mobile terminal 90 effectively receives a signal from any of the branch point transmitters 30, the determination in step S1711 is YES, and subsequently, in step S1712, the signal is acquired from the received signal. Whether or not the transmitter ID matches the transmitter ID acquired during the previous execution of step S1706 described above, that is, whether the mobile terminal 90 continues to effectively receive signals from the same branch point transmitter 30. Judge whether or not.

If the determination in step S1712 is YES, the process returns to step S1709 and the display of the partial map data this time is continued. However, if the determination in step S1712 is NO, the process proceeds to step S1706 and another branch point. The display of the partial map data is started in the same manner as described above.

On the other hand, at the timing shown at time t2 in the example of FIG. 18B, one of the branches is released from the effective reception state in which the climber's mobile terminal 90 effectively receives the signal from any of the branch point transmitters 30. When the transition to the ineffective reception state in which the signal is not effectively received from the point transmitter 30, the determination in step S1711 becomes NO.

After that, the climber's mobile terminal 90 ends the display of the partial map data this time in step S1713 at the timing shown at time t4 in the example of FIG. 18C. After that, the process proceeds to step S1704.

As is clear from the above description, in the present embodiment, for convenience of explanation, the portion of the mountaineer's mobile terminal 90 that executes steps S1704-S1707 in FIG. 17 is an example of the “branch point position specifying portion”. The part of the mountaineer's mobile terminal 90 that executes steps S1701-S1703 in the figure constitutes an example of the "map data receiving unit", and the mountaineer's mobile terminal 90 , It is possible to consider that the portion for executing steps S1708-S1713 in the figure constitutes an example of the “partial map data display unit”.

In addition, although some of the embodiments described above are applied to the application of the present invention as a guide for climbers on the mountain trail 14, they can be applied to other applications.

For example, the present invention can be used to guide pedestrians on other types of mountain roads, guide pedestrians on forest roads, guide visitors on routes within facilities (eg, factories, museums, museums, public facilities, etc.) or Behavior monitoring (existence of entry prohibited areas, entry into dangerous areas, etc.), customer directions in stores where multiple products are displayed, student behavior monitoring on school routes (presence or absence of deviation from regular school routes) Etc.), pedestrian directions on walking paths, bicycle directions on cycling courses, etc. may be applied.

Further, in some embodiments described above, all or part of the processing executed in the mobile terminal 90 may be executed in the management server 50 instead, or conversely, in the management server 50. All or part of the processing executed in the above may be executed in the mobile terminal 90 instead. This is because which device the processing to be executed is executed is usually determined by the circumstances at that time, for example, the amount and type of data handled, the processing speed and storage capacity of each device, and the like. ..

As described above, some of the exemplary embodiments of the present invention have been described in detail with reference to the drawings, but these are examples, and those skilled in the art, including the embodiments described in the [Summary of Invention] column. It is possible to carry out the present invention in other forms with various modifications and improvements based on knowledge.
