In recent years, mountain climbing has attracted attention as a leisure and sport, and the number of mountain climbers is actually increasing. Some climbers are experienced climbers, while others are inexperienced. In addition, not only inexperienced mountaineers but even experienced mountaineers tend to experience the psychological phenomenon of normalcy bias when climbing a mountain they have not experienced, even though they are expected to suffer some kind of damage. This may lead to an unexpected situation where a pedestrian deviates from the normal route (for example, a pedestrian deviates from the normal route).

However, with the above-mentioned conventional technology, climbers who may be in a state of psychological panic can judge whether they are lost, judge whether there is a risk of being lost, and how to avoid being lost. They are forced to decide on their actions and decide whether or not they are truly in distress.

Therefore, with this conventional technology, it is possible to assist the climber in calmly determining whether or not he or she is lost before the climber is lost, and also in assisting the climber in calmly determining whether or not there is a risk of being lost. Nor can it support the accurate selection of actions to avoid distress when there is a risk of distress.

The problem of route deviation, where pedestrians deviate from the normal route, can also occur in activities other than mountain climbing. For example, in environments where pedestrians are likely to lose their sense of direction, for example, when walking in natural environments such as forests and grasslands, on unfamiliar factory tour paths, or when pedestrians are inexperienced such as children and the elderly. It can also occur when walking on the route to school or on a promenade.

Therefore, there is a need for a pedestrian abnormality determination technique that detects that a pedestrian's walking condition is abnormal while walking, and conveys the result to the pedestrian to warn him/her.

It is also a technology that uses a drone to search for pedestrians who have lost their lives while walking, and by switching the communication methods available to the drone depending on the communication status of the pedestrian's communication terminal, it is possible to communicate with the pedestrian. There is also a need for a search technology that dispatches drones to search for pedestrians while securing them.

In addition, it is a technology for rescuing a pedestrian who is in distress while walking by a companion of the pedestrian, which enables the companion to be dispatched to the scene while ensuring the safety of the companion. Dispatch type rescue technology is also required.

It is also a technology that installs multiple transmitters discretely along a walking route in order to guide pedestrians while walking, reducing the number of transmitters that need to be installed while providing effective guidance information. There is also a need for guidance technology that provides pedestrians with information at junctions.

Briefly, as shown in FIG. 2, this system 10 guides a mountain climber (an example of a "pedestrian") who is a user to a mountain trail 14 (an example of a "walking route") in a mountain area 12. For example, in an example of a mountain route), it is determined whether the climber's walking condition is abnormal (such as whether he or she may have gotten lost or deviated from the mountain trail 14), and the results are determined. Climbing that warns climbers by informing them of the danger, and ultimately assists in guiding them along the correct walking route (in the correct direction of travel, along the correct course), thereby preventing accidents. It has a route guidance function.

<Mountain trail guide function>

In this system 10, a plurality of guide transmitters 30 are installed discretely and in series along the mountain trail 14 in order to realize a mountain trail guidance function. The guide transmitters 30 are arranged in series at equal intervals (for example, 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 with variable spacing that decreases as the end of the trail 14 is approached.

Each guide transmitter 30 may be attached to something artificially installed on the mountain trail 14, such as a post or a sign, or may be attached to a natural object growing on the mountain trail 14, such as a natural tree, tree, etc. may be attached to.

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

In order to realize the mountain climbing route guidance function, the mobile terminal 90, alone or in collaboration with the management server 50, monitors the mountain climber's walking route (where to walk) and walking while climbing or descending the mountain. Warnings to climbers (notifying climbers that they may be lost and asking them to be careful) so that they do not deviate from the normal route (in which direction they walk) etc.) and provide route guidance.

Here, a "warning" includes, for example, notifying a climber that he or she may have gotten lost in mountain area 12, calling the climber's attention, urging corrective action, or simply warning the climber. If the user continues to walk, the mobile terminal 90 may notify that the radio waves of the mobile terminal 90 will enter the outside of the communication range where it cannot reach other mobile terminals 90. Examples of out-of-communication areas include areas where there is no ground base station 300 (see FIG. 2) that can receive data nearby, or areas where there are tall trees or neighboring mountains around the climber. There are areas where the radio waves of the mobile terminal 90 are blocked.

In addition, "route guidance (route guidance, course guidance, regular route guidance, etc.)" includes, for example, providing climbers with location and orientation information to correct the actual walking route and course to the official walking route and course. For example, the user may be visually, audibly, or haptically informed of a message to the effect that ``you are lost and should retrace your current route.''

In this example, when the lost mountaineer's mobile terminal 90 detects that he/she is lost using the guide transmitter 30, the mountain climber's mobile terminal 90 uses the guide transmitter 30 to alert the climber and makes a decision to return to the current route. In order to encourage the mountain climber to do so, the message may be output in text, image, or audio, or confirmation that the current climber has confirmed the message may be confirmed by operating a "confirmation button." In this case, the current climber's mobile terminal 90 may continue to display the same button until the "confirm button" is tapped by the user.

Nevertheless, if the "confirm button" is not tapped by the user even if the continuous display time of the "confirm button" exceeds the predetermined time limit, the mobile terminal 90 of the climber this time It is determined that there is a possibility that a certain climber has fallen into an emergency situation (for example, a shipwreck), and this fact is transmitted to the management server 50, and further, the information is sent to each of the other climbers (companions) belonging to the same party. It is transmitted to the mobile terminals 90 all at once.

Furthermore, each climber's mobile terminal 90 is configured to activate its positioning function (for example, a positioning function using GPS, a ground base station 300 The location information is acquired in a time-discrete manner using the positioning function used, and the location information is sequentially transmitted to the management server 50 in order to facilitate search work in the event of a distress.

Upon receiving the position information, the management server 50 sequentially stores the position information in the memory 162 (see FIG. 9) in association with the user ID/device ID of the mobile terminal 90 of each climber. When a mountain climber is in distress, the mountain climber's mobile terminal 90 accesses the management server 50, and the management server 50 extracts the behavior history of the mountain climber in distress from the memory 162. the user's mobile terminal 90. Therefore, the management server 50 and other companions can track the location of the victim from at least the time when the warning was given to the victim.

The behavior history of the victim, that is, the tracking results, is used, for example, in search operations for the victim by other companions or rescue workers. Furthermore, the behavior history of the victim is used by the management server 50 when determining a flight target point for the drone 200, which will be described later.

In this system 10, in order to realize the climbing route guidance function, when the climber's mobile terminal 90 receives an identification signal from any of the guide transmitters 30, the climber's mobile terminal 90 selects one of the guide transmitters 30 as is determined as the reference transmitter (start transmitter, departure point transmitter, etc.) whose passage is confirmed.

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

Furthermore, if the mobile terminal 90 receives the identification signal from the target transmitter before the predetermined time limit f has elapsed from the time when the identification signal was received from the reference transmitter, the mobile terminal 90 determines that the climber's walking condition is normal (the mountain climber's walking condition is normal). On the other hand, if the identification signal is not received from the target transmitter even after the predetermined time limit f has passed, there is an abnormality in the climber's walking condition (the climber may be lost). It is determined that there is a

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

During mountain climbing (while climbing the mountain trail 14) (in the walking route during mountain climbing, in the ascending direction, in the ascending direction), since point B is ahead of point A in the direction of travel, the guide transmitter 30 of point A is the reference transmitter, the guide transmitter 30 at point B becomes the target transmitter.

On the other hand, while descending the mountain (descending the mountain trail 14) (in the walking route during descent, in the descending direction, in the descending direction), point A is in front of point B in the direction of travel, so point B When the guide transmitter 30 is the reference transmitter, the guide transmitter 30 at point A becomes the target transmitter.

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

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

In FIG. 6(a), in this system 10, before a predetermined time limit f has elapsed 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 sent to the adjacent point. A normal gait scenario in which signals are received from the guide transmitter 30 of B is illustratively represented graphically.

On the other hand, in FIG. 6(b), in this system 10, even if the predetermined time limit f has elapsed from the time when the mobile terminal 90 received the signal from the guide transmitter 30 at point A, the same mobile terminal 90 An abnormal walking state scenario in which the user does not receive a signal from the guide transmitter 30 at the neighboring point B is exemplified by a graph.

As shown in FIG. 6(b), in this system 10, if the mobile terminal 90 does not receive a signal from the guide transmitter 30 at the neighboring point B even after the predetermined time limit f has elapsed, the mobile terminal 90 However, the system determines that the climber's walking condition (direction of travel, etc.) is abnormal (for example, he is lost) and issues a warning to the climber.

If the climber does not notice the warning, the climber's mobile terminal 90 or management server 50 may notify the mobile terminals 90 of other accompanying persons that the climber may be in trouble. Send all at once. Furthermore, in order to realize the above-mentioned victim search function, the management server 50 executes a 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 that correlates the order in which the transmitters 30 are lined up and the length of the above-mentioned time limit f is conceptually represented in a table.

The mapping data is originally stored in the memory 162 of the management server 50, and when accessed from any mobile terminal 90, the management server 50 transmits the mapping data to that mobile terminal 90, and thereby, The mobile terminal 90 downloads the 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 is calculated based on the actual distance d and height difference Δh between two adjacent points, assuming a climber with normal athletic ability, and the time limit that the average climber can cover between the two points. This is preset so that the minimum time required for

FIG. 8A shows a graph representing an example in which the altitude changes gradually between two points A and B adjacent to each other on the mountain trail 14. FIG. 4B shows a graph of an example in which the altitude changes suddenly between 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. 8(c) exemplarily shows in a graph that the length of the reference time S increases in accordance with the distance d between the two points A and B. In FIG. 2D, it is exemplarily shown in a graph that the correction coefficient k increases in accordance with the altitude difference Δh between the two points A and B.

<Mutual communication function for companions>

In addition to the above-mentioned mountain trail guidance function, this system 10 supports mutual assistance by allowing multiple climbers belonging to the same party (team, group, etc.) to communicate with each other using their respective mobile terminals 90. It has a mutual communication function for companions. This companion communication function also functions as a function to confirm the safety of the victim.

In this system 10, when multiple people climb a mountain as one party and one climber falls into an emergency situation, the related information is transmitted to the other climbers using the mutual communication function (mutual aid function). By communicating with each other using a mobile terminal 90 and sharing information, it is possible to prevent a distress, to immediately go to rescue, or even if a distress occurs, to search immediately.

Specifically, for example, when multiple people climb a mountain as one party, it becomes clear that one of the climbers has fallen into an emergency situation (for example, the mountain climber's mobile terminal 90 or management server 50 infers the existence of the emergency situation), the climber's mobile terminal 90 or the management server 50 automatically informs the mobile terminals 90 of other climbers in the same party all at once about the emergency situation. wirelessly transmit information about

In one example, the mobile terminals 90 of multiple climbers belonging to the same party automatically attempt to establish mutual connection (for example, without the user's knowledge ), and if there is another mobile terminal 90 to which a connection cannot be established despite this, this fact is reported to the management server 50. The management server 50 determines that the climber who is the user of the other mobile terminal 90 with which the connection is not established may be in an emergency situation, and informs each of the other climbers with whom the connection is established. It is transmitted to the mobile terminals 90 all at once.

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

Here, the "emergency situation" includes, for example, a case where the walking route is not corrected even after the warning is given, a case where a connection with a certain mobile terminal 90 is not established, and the like. In the latter case, for example, a climber may be out of communication range, or the battery of the climber's mobile device 90 may be running low.In either case, if the climber is in trouble, This is a case where it becomes impossible to search for the mountain climber by relying on the mobile terminal 90, and there is a possibility that the search will be difficult.

<Victim search function>

This system 10 has, in addition to the above-mentioned mountain trail guidance function and companion mutual communication function, a lost person search function that searches for the lost person in the event that a mountain climber becomes lost in the mountain area 12. This victim search function also functions to confirm the safety of the victim.

In this system 10, a climber transmitter 32 is attached to a climber before climbing the mountain in order to realize the function of searching for a lost person. The climber transmitter 32 moves together with the wearer, the climber, and the position of the climber transmitter 32 coincides with the position of the climber.

Furthermore, this system 10 includes an unmanned small aircraft, or drone 200, to search for victims from above. The drone 200 can be operated remotely using its own controller 202 and according to instructions from the management server 50, or can be operated autonomously using the controller 202.

When the management server 50 determines that there is a possibility that one of the climbers has been lost, the management server 50 determines the representative spatial coordinates of the mountainous area 12 where the climber is climbing (for example, the specific location of the mountaintop, 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 representing the flight target point, and the controller 202 instructs the drone 200 to dispatch (deploy).

Drone 200 includes a controller 202 and a communication device 204 connected to it. The communication device 204 is capable of wireless communication with the management server 50. This communication device 204 may function as a normal mobile phone (mobile phone) that uses the terrestrial 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 a mobile (movable) aerial base station (hereinafter referred to as a "relay base station") 206 that replaces the fixed ground base station 300 for the mobile terminal 90. are doing. Relay base station 206 receives position information from mobile terminal 90 within its communication range, and transmits the position information to terrestrial base station 300 within communication range of relay base station 206.

The drone 200 further includes a receiver 210 capable of receiving a signal from the climber transmitter 32 of the victim. The controller 202 measures the intensity of the radio waves that the receiver 210 receives from the climber transmitter 32 from time to time. The controller 202 causes the drone 200 to navigate 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 mountain climber in distress, there is a mobile terminal use mode in which the search for the mountain climber is performed by relying on the mobile terminal 90 of the mountain climber, and a mode in which the search is performed by relying on the mountain climber transmitter 32 of the mountain climber. There is also a transmitter use mode that searches for the person in question.

First, to briefly explain, the mobile terminal use mode uses the positioning function and communication function of the mobile terminal 90 to locate a distress site on the condition that a connection is established between the mobile terminal 90 and the management server 50. carried out to search for the person. In this search scenario, the mobile terminal 90, which is one of the equipment of the victim, is directly used to search for the victim.

On the other hand, the transmitter use mode is a state in which a connection is not established between the mobile terminal 90 of the victim and the management server 50, for example, a state in which the battery of the mobile terminal 90 is insufficient, or a state in which the mobile terminal 90 This is executed in order to search for the person in distress by using the location authentication function and transmission function of the climber transmitter 32 in a state where the person is located outside the communication range.

Specifically, in this transmitter use mode, the drone 200 is dispatched, and the receiver 210 mounted on the drone 200 sequentially measures the strength of the radio waves received from the climber's transmitter 32, A flight route for the drone 200 is determined so that the measured value increases over time. As a result, a search scenario in which a person is searched for a person in distress, or a situation where the person in question's mobile terminal 90 operates normally (for example, the battery is not low or the mobile terminal 90 is not malfunctioning) is set. , a search scenario occurs 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. Realized.

In the former search scenario, the climber transmitter 32 as one of the equipment of the victim is directly used by the drone 200 to search for the victim. In contrast, in the latter search scenario, the transmitter usage mode is executed to enable the aforementioned mobile terminal usage mode.

Specifically, in the latter search scenario, when the drone 200 is dispatched and 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 The function establishes a connection between the victim's mobile terminal 90 and the ground base station 300, and in turn establishes a connection between the victim's mobile terminal 90 and the management server 50. In this case, the portable terminal usage mode is executed, and the victim is able to communicate with the management server 50. In this case, for example, the person in distress will be able to talk to the telephone operator of the management center 40 and send data (messaging) via his or her mobile terminal 90.

The drone 200 further includes a camera 220 that photographs the ground from above as a still image or a video. The camera 220 generates imaging data representing images of 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 condition of the ground surface of the mountainous area 12 via the camera 220. This allows the operator of the management center 40 to visually and remotely search for the victim. The operating state (on/off, etc.), photographing 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.

Drone 200 further includes a speaker 230 that outputs audio from above. 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 audio data received from the management server 50, thereby generating and outputting audio. As a result, the operator of the management center 40 can output sound from above toward the mountainous area 12 via the speaker 230.

Thanks to the audio output, the operator of the management center 40 can notify the victim of the current search, the existence of the drone 200, and its current location, by voice, before the victim is found. Furthermore, after a person in distress is found, it is possible to confirm the safety of the person, give instructions on what actions the person should take in order to rescue the person, and provide information regarding the current status of rescue operations.

The drone 200 further includes a shooter 240 that drops or drops necessary items, optionally equipped with a parachute, from the sky toward a target position on the ground. The shooter 240 is remotely controlled by the management server 50 via the controller 202. Items that may be dropped include, for example, relief supplies (for example, a spare charged battery pack that can be used for the victim's mobile device 90, water, food, etc.), and local illumination of the vicinity of the victim to provide relief. There are lighting equipment to make activities easier.

When dropping items from the shooter 240, it is possible to use the speaker 230 to explain the details of the rescue operation audibly using the speaker 230, or to drop lighting equipment as well, in order to draw the attention of the victims. Thanks to the illumination, the victim can accurately determine where the dropped item will land, and will be able to reliably capture the item.

<About guide transmitters and climber transmitters>

FIG. 4 shows a functional block diagram of the guide transmitter 30 and the climber transmitter 32 shown in FIG. 2, both of which have a common configuration. Since the guide transmitter 30 and the climber transmitter 32 have a common configuration, the common configuration will be described below as a representative example of only the guide transmitter 30.

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

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

Next, to explain the operation method, the guide transmitter 30 transmits a unique identification signal actively, locally, without the need for an external trigger signal, and permanently as long as there is no shortage of power supply. send.

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

Next, the hardware configuration will be described with reference to FIG. 4. The guide transmitter 30 is mainly configured with a computer 104 having a processor 100 and a memory 102 that stores a plurality of applications executed by the processor 100. ing.

The guide transmitter 30 further includes a replaceable disposable battery 106 as a power source. Instead of the battery 106, it is possible to use a rechargeable battery, or to use a commercial power source or a solar cell as an external power source.

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

The guide transmitter 30 further includes a transmitter 108 that generates and transmits an identification signal. The transmitter 108 is operated by a battery 106 and controlled by a 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 (eg, carrier signal) to the controller 110 so that the transmitter ID is reflected. The controller 110 controls the transmitter 108, and as a result, the transmitter 108 generates the identification signal to be transmitted this time. Thereafter, the generated identification signal is transmitted from the transmitter 108.

<About mobile devices>

The climber's (user's) mobile terminal 90 is a device that is carried by the user and has a wireless communication function, such as a mobile phone, a smart phone, a laptop computer, a tablet computer, or a PDA. Further, the mobile terminal 90 is an example of a user's communication terminal.

Next, the hardware configuration of the mobile terminal 90 will be described with reference to FIG. The computer 134 has a computer 132 as a main component.

This mobile terminal 90 further includes a display section (for example, a liquid crystal display) 136 that displays information, a receiving section 138 that receives signals from the guide transmitter 30 and the management server 50, and a receiving section 138 that generates and receives signals. and a transmitter 140 that transmits data to the management server 50. Here, the receiving section 138 is also a section that senses the identification signal from the guide transmitter 30.

This mobile terminal 90 further includes an input section 150 for inputting data and commands from the user. The input unit 150 includes, for example, an operation unit that can be operated by the user to input desired information (eg, commands, data, etc.) into the mobile terminal 90. The operating parts include a touch screen that displays icons (e.g., virtual buttons) that can be operated by the user, physical operating parts that can be operated by the user (e.g., a keyboard, keypad, buttons, etc.), and a touch screen that displays user-operable icons (e.g., virtual buttons). Examples include, but are not limited to, a sensing microphone.

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

This 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 transmitted to the mobile terminal 90 and the user carrying it. It is detected as equivalent to the acceleration acting on the

Here, to explain one function of the user's mobile terminal 90 in relation to the guide transmitter 30, the mobile terminal 90, while receiving the identification signal from the guide transmitter 30, When you start (log in) a certain program pre-installed in the computer, that is, a dedicated application for guide transmitter processing (hereinafter referred to as "transmitter application"), it demodulates the received identification signal and The transmitter ID is decoded by the following.

Further, when the mobile terminal 90 starts the transmitter application while receiving the identification signal from the guide transmitter 30, the mobile terminal 90 determines whether the transmitter application is activated based on the received identification signal (for example, the strength of the identification signal). The distance between the position of the guide transmitter 30 when transmitting the identification signal and the position of the mobile terminal 90 when receiving the identification signal is also measured.

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

<Transmitter reception range>

The guide transmitter 30 is apparently assigned two types of reception areas. These are a receivable area and an effective reception area (hereinafter also referred to as "reception range" or "reception area").

Each of these areas is generally defined by a sphere centered on the location where the guide transmitter 30 is installed. Some examples of coverage areas are shown in FIG.

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

The receivable area is an area where the identification signal from the guide transmitter 30 can be reached when the power supply to the guide transmitter 30 is normal, that is, as long as the identification signal exists within the area, the mobile terminal 90 can receive the identification signal. means the area where it can be received.

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 in the mobile terminal 90 using software.

That is, it is possible that the maximum reception radius means a reception limit determined by hardware, whereas the effective reception radius means a reception limit determined by software.

As described above, the mobile terminal 90 measures the distance to the guide transmitter 30 based on the strength of the identification signal it receives. The distance measurement may or may not exceed the effective reception radius. When the measured distance value does not exceed the effective reception radius, it means that the mobile terminal 90 is within the effective reception area, whereas when the measured distance value exceeds the effective reception radius, the mobile terminal 90 exists within the receivable area but not within the effective reception area.

In this embodiment, the reception range of the guide transmitter 30 is set to be, for example, a spherical area with a radius of approximately 0 m to 5 m. That is, the effective reception radius used within the mobile terminal 90 is set to a fixed value within approximately 0 m to 5 m. The effective reception radius may be set, for example, so that the reception range of each guide transmitter 30 covers the entire width of the portion 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, the management server 50 is shown in a functional block diagram in FIG. The management server 50 is mainly configured with a computer 164 having a processor 160 and a memory 162 that stores a plurality of applications executed by the processor 160.

This management server 50 further includes a display section (for example, a liquid crystal display) 166 that displays information, a receiving section 168 that receives signals from the mobile terminal 90, and a receiver section 168 that generates a signal and transmits the signal to the mobile terminal 90. The transmitter 170 has a transmitter 170 and a clock 172. This management server 50 does not directly receive information from the transmitter 30, but actually receives it via the mobile terminal 90.

<Software configuration of mountain trail guidance system>

FIG. 10 conceptually shows a flowchart of a plurality of programs for explaining the software configuration of this system 10. These programs include a mountain trail guidance application (steps S101-S122) as a program executed on each climber's mobile terminal 90, and a program (steps S151-S158) executed on the management server 50.

When the mountain climbing route guidance application is started on the mobile terminal 90 of each mountain climber prior to climbing the mountain trail 14, first, in step S101, a login request to the management server 50 is sent to the management server 50 by the user's operation. personal information of a user who is a mountain climber is input into the mobile terminal 90. The personal information of the climber this time includes, for example, the climber's user ID, the user's name and address, and the telephone number or e-mail address of each of the other companions' mobile terminals 90. The login request and personal information are sent to the management server 50, and then received by the management server 50 in step S151.

Next, in step S102, the user inputs mountain trail identification information for identifying the current mountain trail 14 (for example, the name or ID of the mountain trail 14, the name or ID) is input into 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 mountain trail identification information in the memory 162. Thereafter, in step S153, the management server 50 selects the mountain trail 14, which is represented by the mountain trail identification information received from the mobile terminal 90, from among the plurality of mapping data (see FIG. 7) stored in the memory 162. The corresponding one is read from the memory 162 and transmitted to the current mobile terminal 90.

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

Next, in step S104, the mobile terminal 90 displays a page as shown in FIG. Input data to distinguish between climbing and descending.

In a typical example, first (for example, at the starting point A of the mountain trail 14), the user operates a button representing "climbing" as shown in FIG. The above-mentioned mountain trail guidance mode is activated on the condition that the mountain is being climbed and not descended.

Thereafter, when the user safely arrives at the end point Z of the mountain trail 14 and is about to start descending the mountain, the user presses the "reset" button prior to that, as shown in FIG. 11(a). Then, a button representing "descend" is operated. In response, the above-mentioned mountain trail guidance mode is activated in the mobile terminal 90 from the first step, on the condition that the user is descending a mountain and not climbing a mountain.

Subsequently, the mobile terminal 90 attempts to receive an identification signal from one of the guide transmitters 30 in step S105. Thereafter, the mobile terminal 90 determines whether the identification signal has been effectively received from any guide transmitter 30 in step S106. If the identification signal has not been effectively received (effective reception has failed), the determination is NO and the process returns to step S105. On the other hand, if the identification signal is effectively received (valid reception is successful), the determination in step S106 becomes YES.

The mobile terminal 90 has effectively received an identification signal from one of the guide transmitters 30 (among the plurality of guide transmitters 30, the one closest to the user's current position) (successful reception). If so, then in step S107, the mobile terminal 90 displays a map representing the mountain trail 14 covering the current position and the installation position of one of the received guide transmitters 30 on the screen. and the current position measured using the built-in GPS described above are displayed in an overlay state.

If the mobile terminal 90 is also equipped with an orientation sensor, the user holds the mobile terminal 90 horizontally and determines the orientation of the mobile terminal 90 based on the direction of the map displayed on the screen and the direction of the mobile terminal 90. By adjusting the directions so that they match each other, it becomes possible to visually guide the climber's future direction using the screen.

Thereafter, in step S108, the mobile terminal 90 determines the guide transmitter 30 received this time as the aforementioned reference transmitter.

Subsequently, in step S109, the mobile terminal 90 determines whether or not the user is currently descending the mountain. If you are not descending but climbing a mountain, the determination is NO, and in step S110, among the plurality of guide transmitters 30, when viewed in the ascending direction of the mountain trail 14, the guide transmitter 30 received this time is Another guide transmitter 30 located immediately adjacent is determined as the target transmitter.

Specifically, in the example shown in FIG. The guide transmitter 30 located at the sixth position is determined as the target transmitter.

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

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

In either case, the mobile terminal 90 then attempts to receive an identification signal from the current target transmitter in step S112. Thereafter, in step S113, the mobile terminal 90 determines whether the identification signal has been effectively received from the current target transmitter. If the identification signal has not been effectively received (effective reception has failed), the determination is NO and the process moves to step S115.

In this step S115, the mobile terminal 90 determines whether or not the elapsed time from the initial execution start time of step S112 has not exceeded the time limit f. If not, the determination is YES and the process returns to step S112.

On the other hand, if the mobile terminal 90 effectively receives the identification signal from the current target transmitter (succeeds in effective reception), the determination in step S113 becomes YES.

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

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

Thereafter, in step S116, the mobile terminal 90 determines that the current walking condition of the climber is abnormal. This abnormality determination means, for example, that the climber could not reach the target transmitter and got lost in the section between the reference transmitter and the target transmitter. It means a judgment to that effect.

Subsequently, in step S117, the mobile terminal 90 issues a visual warning to the current climber, as illustrated in FIG. 11(b). In one example, the mobile terminal 90 sends a message to the effect that "You may have lost your way. We recommend that you retrace your route" and confirms that the current climber has read the message. A confirmation button to be operated is displayed in association with each other on the screen.

Thereafter, in step S118, the mobile terminal 90 measures the current position by using the above-mentioned built-in GPS. 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.

In response, the management server 50 receives the location information from the current mobile terminal 90 in step S154 in association with the user ID and current time, and then stores the location information in the memory 162 in step S155. Save in association with the current time. As a result, the memory 162 stores the current history of the climber's actions in chronological order in association with the time, and this information becomes useful information when tracking the climber.

Thereafter, in step S120, the mobile terminal 90 determines whether or not the confirmation button has been operated by the user, as illustrated in FIG. 11(b). If the confirmation button is not operated, the determination is NO, and the mobile terminal 90 determines in step S121 whether or not the elapsed time from the initial execution start time of step S120 has not exceeded the predetermined time limit g. Determine whether If not, the determination is YES and the process returns to step S117. When the elapsed time eventually exceeds the time limit g, the determination in step S121 becomes NO.

Thereafter, in step S122, the mobile terminal 90 determines that the current climber is a lost person, and transmits a request for the aforementioned lost person search mode to the management server 50 to search for the lost person. Subsequently, in step S123, the mobile terminal 90 sends a message saying "we are contacting your companion" and a message saying "we are requesting help", as illustrated in FIG. 11(c). Display on screen.

In response, the management server 50 receives the request for the search mode for the lost person from the current mobile terminal 90 in step S156, and subsequently, in step S157, the management server 50 receives the request for the search mode for the lost person from the current mobile terminal 90. A message is sent all at once to each of the mobile terminals 90 registered in the memory 162 of the management server 50 to notify that the climber may have been lost.

Specifically, for this simultaneous transmission service for all accompanying persons, the management server is linked to each of one or more accompanying persons (for example, members of a party climbing the same mountain trail 14) for the climber. The memory 162 of 50 stores personal information, for example, name, address, age, gender, physical condition data (for example, health data) and athletic ability (for example, years of experience in sports), and contact information, for example, The telephone number, e-mail address, and IP address of each companion's mobile terminal 90 are registered to construct a companion database.

Thereafter, in step S158, the management server 50 dispatches the drone 200 with the current mountain trail 14 as the destination destination. As described above, the drone 200 searches for the climber's position by relying on radio waves received from the climber transmitter 32 worn by the climber. This realizes the aforementioned victim search function.

As is clear from the above description, according to this embodiment, a climber who may be in a state of psychological panic can determine whether or not he or she is lost, and whether or not there is a risk of being lost. It is no longer necessary to select an action to avoid a shipwreck or to judge whether or not a shipwreck has occurred. As a result, according to the present embodiment, a climber can accurately know whether or not he/she is lost or not, and whether or not there is a risk of being lost, before the climber gets lost. In certain cases, it becomes possible to accurately know what actions to take to avoid a disaster.

In this embodiment, it is possible to consider that the part 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 determining part, and It can be considered that the part of the computer 134 of the mobile terminal 90 that executes steps S109 to S111 in the figure constitutes an example of the target transmitter determining part, and , it is possible to consider that the part that executes steps S115 and S116 in the figure constitutes an example of the walking state determination section, and the part that executes step S117 in the figure can be considered to constitute an example of the walking state determination section. It is possible to consider that the portion constitutes an example of the warning portion.

Additionally, in this embodiment, both the first characteristic section functioning as the reference transmitter determining section and the second characteristic section functioning as the target transmitter determining section are the same as the first characteristic section functioning as the walking state determining section. Although the three characteristic parts are also implemented in the computer 134 of the same mobile terminal 90, the present invention may be implemented in a mode in which all three characteristic parts are implemented in the computer 164 of the management server 50 instead. Alternatively, the present invention may be implemented in such a manner that some of these three features are implemented in the computer 164 of the management server 50.

Additionally, in the present embodiment, the mobile terminal 90 is configured to transmit information from the target transmitter on the premise that the climber does not fall off the mountain trail 14 (the climber 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.

In contrast, 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 detect the acceleration of the mobile terminal 90, that is, the mountain climber's acceleration. The 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 trail 14 in the vicinity of the reference transmitter and may have slipped. It may be implemented in the following manner. Here, the "possibility that the climber has slipped from the mountain trail 14" is an example of the aforementioned "abnormal walking condition."

[Second embodiment]

Next, a victim relief system 10 according to a second exemplary embodiment of the present invention will be described in detail based on the drawings. Elements common to the first embodiment described above have the same names or symbols. By using citations, duplicate explanations will be omitted and only different elements will be 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 activates the victim search mode from the current climber's mobile terminal 90 (an example of a "user terminal"). Upon receiving the request, in step S157, each of the mobile terminals 90 (“accompanying terminals”) of the other climbers who are accompanying the current climber and who are registered in the memory 162 of the management server 50 is For example, a message will be sent all at once to inform that the climbers may have been lost. The mobile terminal 90 of each companion has the same structure as the mobile terminal 90 of the mountain climber.

In contrast, in the present embodiment, the management server 50 unconditionally sends the message to all of the multiple companions registered in the memory 162, that is, the current climber, that is, the person in distress. Rather than send a message requesting search and rescue for the person in distress, the companion (or multiple potential rescuers) must be sent to the victim's location without any physical harm to the victim. The risk is narrowed down to those whose risk does not exceed a 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 employed to narrow down the plurality of candidate rescuers to a smaller number of final rescuers.

In the example shown in FIG. 12, the management server 50, from the mobile terminal 90 of each of the plurality of companions, identifies multiple types of personal risks of each companion (if the companion is dispatched to the location of the victim). The risk of an accident affecting the accompanying person is received from the mobile terminal 90 of each accompanying person.

These individual risks include the distance that must be walked to reach the location (estimated location) of the victim (the longer the distance, the greater the risk of an accident for accompanying persons during rescue (e.g., risk of injury, risk of death). In order to measure the current location of each companion, the three-dimensional position (latitude x, altitude y, altitude z) of each companion's mobile terminal 90 is measured by the GPS. There is geographic information (an example of "companion information") to represent.

Another personal risk is that each companion is required to take into account the local weather conditions (another example of "companion information") at each companion's location to determine whether to request assistance 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 an accident for the companion at the time of rescue).

Another personal risk is determining whether it is appropriate to request help from each companion, taking into account other local weather conditions in the location of each companion (yet another example of "companion information"). Therefore, the illuminance is measured by the illuminance sensor of each companion's mobile terminal 90 (the darker the outside world, the higher the risk of an accident for the companion at the time of rescue).

Another personal risk is to determine the pros and cons of requesting assistance from each companion, taking into account the local geographical conditions of each companion's location (yet another example of "companion information"). In addition, there is an altitude (z) measured by the GPS of each companion's mobile terminal 90 (the higher the altitude, the lower the atmospheric pressure and the lower the oxygen concentration, so the risk of an accident for the companion at the time of rescue is higher).

Furthermore, as another personal risk, in order to judge whether or not to request relief from each accompanying person in consideration of the physical condition of each accompanying person, physical condition data (“accompanying information”) on the mobile terminal 90 of each accompanying person (yet another example) input by the user (e.g., graded physical condition levels such as good, normal, and poor; for example, the lower the physical condition level, the more likely the person accompanying the rescuer will be) (high risk of accidents).

Furthermore, as another personal risk, in order to judge whether or not to request rescue from each companion in consideration of each companion's physical condition, the exercise capacity data ("companion information") on the mobile terminal 90 of each companion '') and input by the user (for example, the number of years of experience of the person in sports up to the day of the event; for example, the closer the number of years of experience is to 0, the greater the risk of an accident for the accompanying person at the time of rescue). is high).

In the example shown in FIG. 12, the management server 50 further identifies multiple types of environmental risks for each companion (an example of environmental risks for each companion) based on the weather characteristics of the location of the victim (an example of "environmental information"). The risk of an accident affecting the accompanying person when the person is dispatched to the location is received from the weather server 400 (an example of an "environmental server").

Environmental risks include weather risks (the worse the weather (rainy, snowy, etc.) at the location of the victim (estimated as the position measured by the GPS of the victim's mobile terminal 90), the more likely the person accompanying the victim will be at the time of rescue. There is a high risk of accidents).

Another environmental risk is the temperature risk in the location of the victim (the more the temperature deviates from the appropriate range, the higher the risk of an accident for those accompanying the victim during rescue).

Another environmental risk is the risk of wind speed in the location of the victim (the higher the wind speed, the higher the risk of an accident for those accompanying the victim during rescue).

In the example shown in FIG. 12, the management server 50 further analyzes multiple types of environmental risks for each companion based on the topographical characteristics of the location of the victim (another example of "environmental information"), and the topographical server 500 ( Another example of an "environmental server").

Environmental risks include topographical risks in the location of the victim (for example, the steeper the slope, the higher the risk of an accident for accompanying persons during rescue).

Another type of environmental risk is ground risk in the location of the victim (for example, the higher the likelihood that natural disasters such as landslides, avalanches, and debris flows will occur in mountainous areas, the higher the risk of accidents for accompanying persons during rescue). be.

In the example shown in FIG. 12, the management server 50 stores, for each companion, the location of the companion (more precisely, the distance D between the companion and the victim) and the location of the companion. Temperature T (Temperature), illuminance L (Lightness) at the location of the companion, altitude H (Height) at the location of the companion, physical condition C (Condition) of the companion, and exercise ability M of the companion. (Motor Skill), calculate the total individual risk F as shown in the following formula.

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 coefficients by which each risk variable is multiplied (default value)

The larger the calculated value of the total individual risk F, the higher the risk of an accident for the accompanying person during rescue.

In the example shown in FIG. 12, the management server 50 determines, for each victim, the weather risk M ₁ , temperature risk M ₂ , wind speed risk M ₃ , terrain risk S ₁ , and ground risk at the location of the victim. From _S2 , the total environmental risk G is calculated as shown in the following equation.

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 : Weight coefficients by which each risk variable is multiplied (default value)

The larger the calculated value of the total environmental risk G, the higher the accident risk for accompanying persons during rescue.

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

As shown in FIG. 10, when the management server 50 receives a request for the victim search mode from the current mobile terminal 90 in step S156, as shown in FIG. 13, in step S1351, the management server 50 A request for requesting personal risk from a person (each candidate rescuer) is simultaneously transmitted to all of the plurality of mobile terminals 90 of the plurality of companions.

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

Subsequently, in step S1303, each companion's mobile terminal 90 detects the temperature (air temperature) T at each companion's location using the temperature sensor of each companion's mobile terminal 90. Furthermore, the illuminance L at each companion's location is detected by the illuminance sensor of each companion's mobile terminal 90. Furthermore, the altitude H of each companion's location is detected using the GPS of each companion's mobile terminal 90.

Thereafter, in step S1304, each companion's mobile terminal 90 converts the plurality of detection values T, L, H to the level of physical condition C of each companion's mobile terminal 90 input by the user ( For example, the higher the companion's fatigue level, the higher the level) and the level of the exercise ability M of each companion's mobile terminal 90 input by the user (for example, the lower the companion's exercise ability, the higher the level). (increasing level), and each of them is sent to the management server 50 as a personal risk.

In response, the management server 50 receives these personal risks from the mobile terminals 90 of each companion in step S1352, and then associates the received personal risks with each companion in step S1353 and stores them in memory. 162.

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

Thereafter, 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, together with the set rescue point.

Each of the weather server 400 and the terrain server 500 receives the request in step S1371, and subsequently covers the relief point in the weather database of the weather server 400 and the database of the terrain server 500, respectively, in step S1372. Search for environmental risks in a certain area.

Thereafter, each of the weather 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, in step S1357, the management server 50 calculates the total environmental risk G for the plurality of received environmental risks as described above.

Subsequently, in step S1358, the management server 50 determines whether the calculated value of the total environmental risk G is less than or equal to a preset upper limit (an example of a "second standard value"), that is, whether or not the calculated value of the comprehensive environmental risk Determine whether the risk of accidents is low. If the calculated value is less than or equal to the upper limit, the determination is YES, and rescue by one of the companions is permitted in step S159; however, if the calculated value is higher than the upper limit, step S1358 If the determination is NO, for example, the process returns to step S1351 and it is determined whether to wait for the environmental risk to improve for the same rescue point or to decide whether to rescue another rescue point.

After executing step S1359, the management server 50 calculates the total personal risk F for each candidate rescuer (each companion) from the received plurality of personal risks in step S1360. Thereafter, in step S1361, the management server 50 selects, among the plurality of candidate rescuers, those whose calculated overall personal risk F is less than or equal to a preset reference point (an example of a "first reference value"). Each will be selected as the final savior.

Subsequently, in step S1362, the management server 50 sends a message to the mobile terminal 90 of each selected rescuer requesting search and rescue for the victim, including the name, estimated location, and physical condition of the victim. Submit with characteristics and clothing characteristics.

In response, each rescuer's mobile terminal 90 displays the received message on the screen (or outputs it as voice) and further displays a confirmation button on the screen in step S1306. Thereafter, on the condition that the confirmation button is operated by the user of the mobile terminal 90, that is, the rescuer, the corresponding rescuer operates the confirmation button on the mobile terminal 90 of each rescuer in step S1307. , thereby transmitting an intention to accept the rescue request to the management server 50.

In response, in step S1363, the management server 50 receives information from the mobile terminal 90 of one of the rescuers indicating that the confirmation button has been operated, identifies the rescuer who has accepted the rescue request, and stores the information in the memory 163. Register.

However, if the management server 50 cannot receive information indicating that the confirmation button has been operated from any of the rescuers' mobile terminals 90 even after the time limit has elapsed, the management server 50 changes the reference point to 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. As a result, the next execution of step S1361 expands the range of rescuers to whom a rescue request can be made, thereby increasing the probability that a rescuer who accepts the rescue request will be found.

As is clear from the above description, in this embodiment, for convenience of explanation, the part of the climber's mobile terminal 90 that executes steps S105-S117 and S120-S122 in FIG. It can be considered that this constitutes an example of ``. An example of the "Victim Judgment Unit" is one that uses a plurality of guide transmitters 30 as external devices of the mobile terminal 90 to determine the Victim, but another example of the "Victim Judgment Unit" is , the above-mentioned acceleration sensor 154 (an example of a motion sensor that measures the behavior of a mountain climber) is used to determine whether a person is in distress as described above.

Furthermore, in this embodiment, for convenience of explanation, the part of the management server 50 that executes steps S1352 and S1360 in FIG. , the part that executes steps S1354 to S1357 in the figure constitutes an example of the "environmental risk calculation unit", and the part of the management server 50 that executes step S1359 in the figure constitutes an example of the "relief permitting unit". The portion of the management server 50 that executes steps S1361 and S1364 in the figure constitutes an example of the "rescuer selection section," and the part of the management server 50 that executes steps S1361 and S1364 in the figure It is possible to consider that the part that executes step S1362 constitutes an example of a "rescue requesting part".

[Third embodiment]

Next, a mountain trail guide system 10 according to a third exemplary embodiment of the present invention will be described in detail based on the drawings. By using citations, duplicate explanations will be omitted and only different elements will be explained in detail. System 10 is designed to implement a pedestrian guidance method according to an embodiment of the invention.

As described above, in the first embodiment, as shown in FIG. It is installed regardless of the Then, if the time required for the climber to walk from one guide transmitter 30 to the next guide transmitter 30 exceeds the time limit, it is determined that the climber may have gotten lost. Ru.

On the other hand, in general, the cause of the possibility that a climber gets lost on a mountain trail is not the straight part of the mountain trail 14 but the part where there is a branch point. Rather than installing the transmitters 30 all over the same mountain trail 14 as guide transmitters, only at branch points (or among multiple branch points, statistically or empirically, the climber is on the route). 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 this embodiment, as illustrated in FIG. 14, branch point transmitters 30 are installed only at a plurality of branch points on the mountain trail 14.

Furthermore, in the present embodiment, when the climber's mobile terminal 90 starts receiving signals from any of the branch point transmitters 30, in response, the mountain trail 14 is displayed on the screen as illustrated in FIG. Of these, a map image representing only the area near the current junction is displayed along with a mark representing the climber's current location, a mark representing the correct course, and the junction name (in addition, climbing information useful for climbers, etc.) The operation to be performed is started.

Thereafter, when the mobile terminal 90 no longer receives a signal from the same branch point transmitter 30, the map image that had been displayed until then disappears from the screen.

Furthermore, in this 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 the entirety of 14 is constructed. However, in this embodiment, for convenience of explanation, the map database is constructed so that it is effective only when a climber climbs the mountain trail 14 toward the summit.

Therefore, when any destination is specified, one piece of 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 exemplified in FIG. 15, each partial map data is determined based on the relationship between the corresponding branch point, at least three routes of the mountain trail 14 that intersect at that branch point, and the destination designated by the climber. and a mark representing the course in association with its position.

Although not shown, the memory 162 of the management server 50 further includes a transmitter ID represented by an identification signal transmitted by each branch point transmitter 30 and a branch point where 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 a signal from any branch point transmitter 30, one transmitter ID is specified, one branch point ID is further specified, and one piece of partial map data is specified. be identified.

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

FIG. 18A shows a perspective view of an example of a mountain climber walking through a branch point while the system 10 is in operation. FIG. 4B shows a time chart that shows temporal changes in the state in which the mobile terminal 90 receives one of the branch point transmitters 30 in the walking example shown in FIG. FIG. 4(c) shows a time chart showing temporal changes in the display state on the screen of the mountain climber's mobile terminal 90 in the walking example of FIG. 4(a).

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

In response, the management server 50 receives the request in step S1731, and then, in step S1732, the management server 50 uses the destination received from the mobile terminal 90 as a key in the map database to Search for map data. Thereafter, in step S1733, the management server 50 transmits the retrieved current map data (a collection of a plurality of partial map data) to the climber's mobile terminal 90.

In response, the climber's mobile terminal 90 receives the current map data 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 current destination.

Subsequently, the climber's mobile terminal 90 attempts to receive a signal from one of the branch point transmitters 30 in step S1704. Thereafter, in step S1705, the climber's mobile terminal 90 determines whether or not the mobile terminal 90 has effectively received a signal from any of the branch point transmitters 30. It is determined whether or not the receiver exists within the reception range (effective reception area) of the device 30. If the signal is not being effectively received, the determination is NO and the process returns to step S1704; however, if the signal has started to be effectively received, the determination is YES.

In the example of FIG. 18(b), if the determination in step S1705 becomes YES at the timing indicated by 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.

Thereafter, in step S1708, the climber's mobile terminal 90 selects the partial map data that corresponds to the current branch point ID from among the plurality of partial map data stored in the memory 132 of the mobile terminal 90, and selects the partial map data that corresponds to the current branch point ID. Read data from memory 132. Subsequently, in step S1709, the climber's mobile terminal 90 displays the read partial map data on the screen as illustrated in FIG. 15 at the timing indicated by time t3 in the example of FIG. 18(c). start doing.

Subsequently, the climber's mobile terminal 90 attempts to receive a signal from one of the branch point transmitters 30 in step S1710. Thereafter, in step S1711, the climber's mobile terminal 90 determines whether or not the mobile terminal 90 has effectively received a signal from any of the branch point transmitters 30. It is determined whether or not the receiver exists within the reception range (effective reception area) of the device 30.

If the climber's mobile terminal 90 has effectively received 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 the transmitted transmitter ID matches the transmitter ID obtained 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. Determine whether or not.

If the determination in step S1712 is YES, the process returns to step S1709 and the display of the current partial map data is continued, but if the determination in step S1712 is NO, the process advances to step S1706 and another branch point is displayed. , display of partial map data is started in the same manner as described above.

On the other hand, at the timing indicated by time t2 in the example of FIG. When transitioning to an ineffective reception state in which no signal is effectively received from the point transmitter 30, the determination in step S1711 becomes NO.

Thereafter, the climber's mobile terminal 90 ends the display of the current partial map data in step S1713 at the timing indicated by time t4 in the example of FIG. 18(c). After that, the process moves to step S1704.

As is clear from the above description, in this embodiment, for convenience of explanation, the portion of the climber's mobile terminal 90 that executes steps S1704 to S1707 in FIG. The portion of the climber's mobile terminal 90 that executes steps S1701 to S1703 in the figure constitutes an example of a "map data receiving section." , it is possible to consider that the part that executes steps S1708 to S1713 in the figure constitutes an example of a "partial map data display part".

Additionally, in the several embodiments described above, the present invention is applied to the use of guiding climbers on the mountain trail 14, but it is possible to apply it to other uses.

For example, the present invention can be used to guide pedestrians on other types of mountain roads, guide pedestrians on forest roads, guide tours for visitors in facilities (e.g., factories, art museums, museums, public facilities, etc.), or Monitoring of behavior (entering prohibited areas, dangerous areas, etc.), guiding customers in stores where multiple products are displayed, monitoring student behavior on school routes (whether or not they deviate from the regular school route) etc.), may be applied to uses such as route guidance for pedestrians on walking paths, route guidance for bicycles on cycling courses, etc.

Furthermore, in some of the embodiments described above, all or part of the processing that was being executed on the mobile terminal 90 may be executed on the management server 50 instead, or conversely, the processing executed on the mobile terminal 90 may be executed on the management server 50. All or part of the processing that was executed in the mobile terminal 90 may be executed in the mobile terminal 90 instead. This is because the device on which a process is to be executed is usually determined by the circumstances at the time, such as the amount and type of data being handled, the processing speed and storage capacity of each device, etc. .
