Abstract

This invention discloses a navigation device for tourists who get lost in mountainous scenic areas, comprising: a rest station, a lost-aware warning mechanism, a geomagnetic signal transmitting component, a signal tracking device, and a first control system. The rest station is located on the main road of the scenic area. The lost-aware warning mechanism is located at the rest station and includes a first driving mechanism and a thermal imager. The first driving mechanism drives the thermal imager to swing up and down along the direction of gravity to identify whether tourists have left the main road of the scenic area. The first control system sends a reminder signal to the signal tracking device carried by the tourist based on the information from the thermal imager to avoid getting lost. After getting lost, the tourist uses the signal tracking device to send a distress signal. The first control system receives the distress signal and drives the geomagnetic signal transmitting component to send an electromagnetic signal. The signal tracking device receives the electromagnetic signal and, through changes in the strength of the electromagnetic signal, helps the tourist find the nearest rest station, thereby helping tourists to save themselves in extreme weather conditions such as dense fog and heavy rain.

Description

Technical Field

[0001] This invention relates to the field of smart tourism technology, and in particular to a navigation device and method for tourists to find themselves lost in mountainous scenic areas. Background Technology

[0002] Mountainous scenic areas have complex terrain and changeable weather, and are particularly prone to low visibility weather such as dense fog, rain and snow, which poses a serious challenge to the safety of tourists.

[0003] Currently, navigation and self-rescue devices deployed in scenic areas mainly employ optical guidance. For example, Chinese patent document CN113674655A discloses a navigation device for preventing loss and positioning in scenic areas. Its core function is to project colored arrows towards the tourist's location using an adjustable beam emitter, guiding lost tourists to the nearest navigation device. This solution is effective in good weather. However, in extreme weather conditions such as dense fog or heavy rain, the beam intensity is severely attenuated, making it impossible for tourists to observe and thus unable to assist in self-rescue. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this invention is to provide a navigation device for tourists who are lost in mountainous scenic areas, which can still help tourists save themselves in extreme weather conditions such as dense fog and heavy rain.

[0005] The objective of this invention is achieved through the following technical solution: a self-rescue navigation device for lost tourists in mountainous scenic areas, comprising: a rest station, a lost warning mechanism, a geomagnetic signal transmitting component, a signal tracking component, and a first control system;

[0006] The rest stop is located on the main road of the scenic area;

[0007] The lost-way warning mechanism is located at the rest station. The lost-way warning mechanism includes at least one first drive mechanism and a thermal imager. The first drive mechanism is driven to the thermal imager so that the thermal imager can swing up and down along the direction of gravity. The thermal imager is used to identify whether tourists have left the main road of the scenic area.

[0008] The geomagnetic signal transmitting component is located at the rest station, and the geomagnetic signal transmitting component is used to transmit geomagnetic signals to the external environment;

[0009] The signal tracking device is for tourists to carry with them, and the signal tracking device is connected to the geomagnetic signal transmitting component via electromagnetic signals.

[0010] The disorientation warning mechanism, the geomagnetic signal transmitting component, and the signal tracking component are all electrically connected to the first control system.

[0011] Furthermore, the rest station is equipped with a top beam column, which has an accommodating space;

[0012] The self-rescue navigation device for lost tourists in mountainous scenic areas further includes a second drive mechanism, which is located within the accommodating space. The second drive mechanism includes a vertical threaded rod, a first motor, a first bevel gear, a second bevel gear, and a lifting rod. The vertical threaded rod is rotatably mounted within the accommodating space. The first bevel gear is sleeved around the drive shaft of the first motor. The first bevel gear meshes with the second bevel gear. The second bevel gear is sleeved around the vertical threaded rod. The lifting rod is sleeved around the vertical threaded rod, so that when the first motor drives the first bevel gear to rotate, the first bevel gear drives the vertical threaded rod to rotate via the second bevel gear, enabling the lifting rod to rotate and move up and down along the length of the vertical threaded rod.

[0013] The disorientation warning mechanism is installed on the top of the lifting rod to follow the rotation and lifting motion of the lifting rod.

[0014] Furthermore, the disorientation warning mechanism also includes a rain cover, which is located on the top of the lifting rod;

[0015] The thermal imager is located within the cover space of the rain cover and is supported by the rain cover.

[0016] The first drive mechanism has at least two components, which are located on opposite horizontal sides of the rain cover. Each first drive mechanism includes a swing rod and an electric push rod. The swing rod is pivotally connected to the thermal imager so that the swing side of the swing rod can swing around the pivot side of the swing rod. The electric push rod is located at the top of the lifting rod. The telescopic part of the electric push rod is connected to the swing side of the swing rod through a horizontal shaft. The electric push rod is electrically connected to the first control system.

[0017] Furthermore, the rest station is equipped with an underground cabin, and the geomagnetic signal transmitting component is located in the underground cabin. The geomagnetic signal transmitting component includes a second motor and a permanent magnet coil. The rotor of the permanent magnet coil is sleeved outside the drive shaft of the second motor so as to rotate with the drive shaft of the second motor.

[0018] Furthermore, the signal tracking device is a wristband, which is equipped with an alarm, a second control system, a vibration motor, a magnetoresistive sensor, and an indicator light. The alarm is electrically connected to the second control system to send an alarm signal; the second control system is electrically connected to the first control system, the vibration motor, the magnetoresistive sensor, and the indicator light; the magnetoresistive sensor is used to receive geomagnetic signals; the indicator light can change its flashing frequency to remind tourists that they are moving closer to or further away from the rest station.

[0019] Furthermore, the tourist self-rescue navigation device suitable for mountain scenic areas also includes a polarized beam emitter. The polarized beam emitter is installed on the lifting rod and moves up and down with the lifting rod to scatter the polarized beam into the external environment in an undirected manner, or to irradiate adjacent rest stations belonging to different tourist self-rescue navigation devices suitable for mountain scenic areas in a directed manner. The polarized beam emitter is electrically connected to the first control system.

[0020] Furthermore, the polarized beam emitter is a plurality of such emitters, which are distributed at intervals around the axis of the lifting rod.

[0021] Furthermore, the self-rescue navigation device for lost tourists in mountainous scenic areas also includes a self-service component, which includes a navigation station, a wired telephone, and a loudspeaker. The navigation station is used for tourists to plan navigation routes. The navigation station is electrically connected to the first control system. The navigation station is equipped with a first-aid supplies compartment. The door of the first-aid supplies compartment is equipped with a sensor switch. The sensor switch is electrically connected to the first control system and the second control system. The wired telephone and the loudspeaker are both installed on the navigation station.

[0022] Furthermore, the rest station is equipped with multiple roller shutter mechanisms, one of which is located at one of the exits of the rest station. Each roller shutter mechanism includes a third motor, a horizontal rotating shaft, an insulated curtain, and a dustproof shell. The third motor is mounted on one of the load-bearing columns of the rest station. One end of the horizontal rotating shaft is sleeved on the drive shaft of the third motor, and the other end is mounted on another load-bearing column of the rest station, rotating with the drive shaft of the third motor. One end of the insulated curtain is mounted on the horizontal rotating shaft and rotates with it, allowing the curtain to be lowered or rolled up from the horizontal rotating shaft. Insulated curtains belonging to multiple different roller shutter mechanisms are lowered together to separate the resting space of the rest station from the external environment. The dustproof shell is connected at both ends to two adjacent load-bearing columns of the rest station for support, and it is used to shield the horizontal rotating shaft and the insulated curtain.

[0023] This invention also provides a method for using a self-rescue navigation device for lost tourists in mountainous scenic areas. The method includes the following steps:

[0024] Step 1: When the thermal imager detects that a tourist has left the main trail and entered an undeveloped area, the first control system sends a signal to the second control system, which then controls the vibration motor to vibrate and alert the tourist.

[0025] Step 2: After a tourist gets lost, they press the alarm on their wristband, and the second control system sends an alarm signal to the first control system.

[0026] Step 3: The first control system controls the geomagnetic signal transmitting component to emit a magnetic signal. After receiving the magnetic signal, the magnetoresistive sensor sends a command to the second control system. The second control system obtains the straight-line distance between the tourist and the rest station and drives the indicator light to flash.

[0027] Step 4: Tourists move to the rest station according to the flashing frequency of the indicator lights. If the tourist is in good health: After planning the movement route in the navigation station, the first control system drives the polarized light emitter to emit a polarized beam of light to the next rest station on the movement route. Tourists proceed to the next rest station according to the direction of the polarized beam. If the tourist is in poor health: After making a wired phone call, the tourist waits for rescue on the spot. Tourists can use the wristband to touch the sensor switch to open the first aid supply compartment to obtain first aid supplies, and can also close multiple roller shutter mechanisms to maintain body temperature.

[0028] Step 5: After the tourists move to the corresponding rest station, the polarized light emitter of that rest station emits a polarized light beam to the next rest station on the moving route, and so on until the tourists move to the end of the planned route or the scenic area exit.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] 1. The lost-way warning mechanism includes at least one first driving mechanism and a thermal imager. The first driving mechanism is driven to connect with the thermal imager (e.g., hinged, or movable), so that the thermal imager can swing up and down along the direction of gravity, thereby flexibly adjusting the pitch angle and scanning coverage of the thermal imager. The thermal imager is used to identify whether tourists have left the main road of the scenic area. Based on the principle of thermal radiation imaging, the thermal imager can clearly identify the heat source outline of moving tourists, thereby determining whether tourists have deviated from the main road of the scenic area. This detection method is not affected by low visibility weather such as dense fog and heavy rain, ensuring effective early warning monitoring and reducing the risk of tourists getting lost.

[0031] 2. The geomagnetic signal transmitting component is fixedly installed in the rest station. Its core function is to continuously transmit low-frequency electromagnetic signals with specific frequency and stable intensity into the surrounding environment. It is not affected by dense fog or heavy rain, so that it can be received by lost tourists and ensure that tourists can find the nearest rest station even in extreme weather conditions so that they can get further assistance from the rest station.

[0032] 3. The signal tracking device is for tourists to carry with them so that they can send a distress signal to rest stops if they get lost, and receive electromagnetic signals from the geomagnetic signal transmitter to find the nearest rest stop. Since only the signal tracking device that sends a distress signal can receive the electromagnetic signal from the geomagnetic signal transmitter, it avoids disturbing tourists who are enjoying their visit.

[0041] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0042] It should be noted that when an element is described as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is described as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0044] like Figures 1 to 4 As shown, a preferred embodiment of the present invention is a self-rescue navigation device for lost tourists in mountainous scenic areas, comprising: a rest station 1, a lost warning mechanism 2, a geomagnetic signal transmitting component 3, a signal tracking component 4, and a first control system 5;

[0045] The rest station 1 is located on the main road of the scenic area, and the trees planted around the rest station 1 are low and easy for tourists to find. The rest station 1 is a common building or structure with a canopy and seats for tourists to take shelter from the rain and sit on. The rest stations 1 belonging to different tourist self-rescue navigation devices are set up at intervals along the extension direction of the main road of the scenic area (for example, one rest station 1 is set up every 500 meters), thereby covering the entire mountain scenic area and ensuring that tourists can find the nearest rest station 1 no matter where they get lost in the scenic area. This is the basis for tourists to achieve self-rescue.

[0046] The lost-way warning mechanism 2 is located at the rest station 1. It should be installed at the top or high point of the rest station 1 to obtain the best overhead view. The lost-way warning mechanism 2 includes at least one first drive mechanism 21 and a thermal imager 22. The first drive mechanism 21 is driven to connect with the thermal imager 22 (e.g., hinged, or movable), allowing the thermal imager 22 to swing up and down along the direction of gravity, thereby flexibly adjusting the pitch angle and scanning coverage of the thermal imager 22. The thermal imager 22 is used to identify whether tourists have left the main road of the scenic area. Based on the principle of thermal radiation imaging, the thermal imager 22 can clearly identify the heat source outline of moving tourists, thereby determining whether tourists have deviated from the main road of the scenic area. This detection method is not affected by low-visibility weather such as dense fog or heavy rain, ensuring effective early warning monitoring and reducing the risk of tourists getting lost.

[0047] The geomagnetic signal transmitting component 3 is located at the rest station 1. The geomagnetic signal transmitting component 3 is used to transmit geomagnetic signals to the external environment. The geomagnetic signal transmitting component 3 is fixedly installed in the rest station 1. Its core function is to continuously transmit low-frequency electromagnetic signals with specific frequency and stable intensity to the surrounding environment. It is not affected by dense fog or heavy rain, so that it can be received by lost tourists and ensure that tourists can find the nearest rest station 1 even in extreme weather conditions so that they can get further assistance from the rest station 1.

[0048] The signal tracking device 4 is for tourists to carry with them. The signal tracking device 4 is connected to the geomagnetic signal transmitting component 3 via electromagnetic signals. Each tourist receives a signal tracking device 4 from the scenic area operator upon entering the area. The operator must ensure that each signal tracking device 4 is functional and has sufficient power. Tourists must carry this device to send a distress signal to rest station 1 if they get lost, and to receive electromagnetic signals from the geomagnetic transmitting component, thus finding the nearest rest station 1. It should be noted that only the signal tracking device 4 that sends a distress signal can receive electromagnetic signals from the geomagnetic signal transmitting component 3, thus avoiding disturbing tourists who are enjoying their visit.

[0049] The lost-in-the-way warning mechanism 2, the geomagnetic signal transmitting component 3, and the signal tracking device 4 are all electrically connected to the first control system 5. The working principle of this invention is as follows: the first driving mechanism 21 drives the thermal imager 22 to swing up and down, scanning unspecified tourists moving within the scenic area. The first control system 5 receives images transmitted in real time by the thermal imager 22. Once it is detected that a tourist has left the main road of the scenic area and entered an undeveloped area, it proves that the tourist is in danger of getting lost. The first control system 5 transmits a signal to the signal tracking device 4 carried by the tourist. The signal tracking device 4 sends a signal (e.g., one or any combination of sound signals, vibration signals, light signals, etc.) to the tourist, thereby prompting the tourist to stop. If tourists insist on entering undeveloped areas within the scenic area and get lost, they can use the signal tracking device 4 to send a distress signal to the first control system 5. After receiving the distress signal, the first control system 5 controls the geomagnetic signal transmitting component 3 to emit electromagnetic signals of a specific frequency. The signal tracking device 4 receives the electromagnetic signals and displays their intensity. Tourists can observe changes in the intensity of the electromagnetic signals by making tentative movements (e.g., pacing around) (the signal becomes stronger when approaching rest station 1), thus identifying the approximate location of rest station 1. By continuing to move in the direction of the increasing electromagnetic signal, tourists can return to the main road of the scenic area and find rest station 1, thereby achieving self-rescue.

[0050] like Figures 1 to 3 As shown, preferably, the rest station 1 is provided with a top beam 11, which has an accommodating space 111. As a preferred design, the top beam 11 is located at the center of the rest station 1 and extends from the top of the rest station 1 to lay the foundation for a better overlook view; the interior of the top beam 11 is hollow to form the accommodating space 111.

[0051] The self-rescue navigation device for lost tourists in mountainous scenic areas also includes a second drive mechanism 6. The second drive mechanism 6 is located within the accommodating space 111, so that it is protected by the top beam 11 and prevented from being eroded by rainwater. The second drive mechanism 6 includes a vertical threaded rod 61, a first motor 62, a first bevel gear 63, a second bevel gear 64, and a lifting rod 65. The vertical threaded rod 61 is installed within the accommodating space 111, with one end inserted into a positioning hole at the bottom of the accommodating space 111. The first bevel gear 63 is sleeved around the drive shaft of the first motor 62. The first bevel gear 63 meshes with the second bevel gear 64. The second bevel gear 64 is sleeved around the vertical threaded rod 61 and threadedly connected to the vertical threaded rod. The lifting rod 65 is sleeved around the vertical threaded rod 61 and threadedly connected to the vertical threaded rod. The threaded rod 61 is connected by a thread, and the lifting rod 65 slides against the inner wall of the accommodating space 111. When the first motor 62 drives the first bevel gear 63 to rotate, the first bevel gear 63 drives the vertical threaded rod 61 to rotate through the second bevel gear 64, so that the lifting rod 65 can rotate and move up and down along the length direction of the vertical threaded rod 61. It can be understood that when the first motor 62 starts, it drives its motor output shaft to rotate, thereby driving the first bevel gear 63 to rotate in a direction perpendicular to the vertical threaded rod 61, and then driving the second bevel gear 64 to rotate around the axis of the vertical threaded rod 61. Since the second bevel gear 64 is sleeved on the outside of the vertical threaded rod 61, the threaded pair converts the rotational motion into linear motion along the axis of the vertical threaded rod 61. Therefore, the lifting rod 65 will simultaneously generate rotation around the axis of the vertical threaded rod 61 and linear up and down along its length direction, realizing a helical motion of rotation and up and down.

[0052] The disorientation warning mechanism 2 is installed on the top of the lifting rod 65. The top of the lifting rod 65 extends radially to form a lifting platform, on which the disorientation warning mechanism 2 is installed to allow the thermal imager 22 to obtain a wider overhead view and to follow the rotation and lifting movement of the lifting rod 65. Specifically, the second drive mechanism 6 is responsible for driving the entire lifting rod 65 and the disorientation warning mechanism 2 on its top to rotate and lift, thereby adjusting the vertical height and horizontal orientation of the thermal imager 22; while the first drive mechanism 21 is used to independently drive the thermal imager 22 to swing up and down along the direction of gravity after the height and orientation are positioned, thereby adjusting the pitch scanning angle of the thermal imager 22. The first drive mechanism 21 and the second drive mechanism 6 work together to achieve multi-directional monitoring of the tourist's activity range by the thermal imager 22.

[0053] like Figure 1 and Figure 5As shown, preferably, the disorientation warning mechanism 2 further includes a rain cover 23, which is located on top of the lifting rod 65; the thermal imager 22 is located within the cover space of the rain cover 23 and is supported by the rain cover 23; the rain cover 23 forms a downward-opening protective space, in which the thermal imager 22 is located, and each side of the thermal imager 22 is connected to the side wall of the rain cover 23 by a connecting rod, thereby protecting it from direct rain and snow.

[0054] The first drive mechanism 21 has at least two components, which are located on opposite horizontal sides of the rain cover 23. Each first drive mechanism 21 includes a swing rod 211 and an electric push rod 212. On opposite horizontal sides of the rain cover 23, there is a set of first drive mechanisms 21, each set including a swing rod 211 and an electric push rod 212. The swing rod 211 is pivotally connected to the thermal imager 22, allowing its swing side to swing around its pivot point. The inner end of the swing rod 211 is pivotally connected to the corresponding side (connecting rod) of the thermal imager 22, allowing it to swing around the pivot point. The electric push rod 212 is located at the top of the lifting rod 65. The telescopic part of the electric push rod 212 is connected to the swing side of the swing rod 211 via a horizontal shaft. The electric push rod 212 is electrically connected to the first control system 5. The electric push rod 212 is fixed to the top of the lifting rod 65 by fasteners (e.g., rivets). The end of the telescopic rod of the electric push rod 212 is hinged to the outer end of the swing rod 211 via a horizontal shaft. When the electric push rods 212 on both sides extend and retract synchronously under the control of the first control system 5, they can push or pull the swing rods 211 on both sides together, thereby causing the thermal imager 22 to pitch and swing around the pivot side of the swing rod 211, thereby adjusting the detection angle of the thermal imager 22.

[0055] like Figure 1 and Figure 4 As shown, preferably, the rest station 1 is provided with an underground cabin 12, and the geomagnetic signal transmitting component 3 is located in the underground cabin 12. The geomagnetic signal transmitting component 3 includes a second motor 31 and a permanent magnet coil 32. The rotor of the permanent magnet coil 32 is sleeved outside the drive shaft of the second motor 31 so as to rotate with the drive shaft of the second motor 31.

[0056] like Figures 1 to 5As shown, preferably, the signal tracking device 4 is a wristband, which is convenient for tourists to wear on their wrists and is not easily lost; the wristband is equipped with an alarm 41, a second control system 42, a vibration motor 43, a magnetoresistive sensor 44, and an indicator light 45. The alarm 41 is electrically connected to the second control system 42 to send an alarm signal; the second control system 42 is electrically connected to the first control system 5, the vibration motor 43, the magnetoresistive sensor 44, and the indicator light 45; the magnetoresistive sensor 44 is used to receive geomagnetic signals; the indicator light 45 can change its flashing frequency to remind tourists that they are moving closer to or further away from rest station 1. The second control system 42 is the signal processing unit of the wristband. It maintains a wireless connection with the first control system 5 in rest station 1. Through the detection image of the thermal imager 22, the first control system 5 transmits a signal to the second control system 42 on the wristbands of tourists leaving the main road of the scenic area. The second control system 42 drives the vibration motor 43 to vibrate and remind tourists to stop. If tourists insist on entering the undeveloped area of ​​the scenic area and get lost, they press the alarm, which prompts the second control system 42 to send a distress signal to the first control system 5. After receiving the distress signal, the first control system 5 controls the geomagnetic signal transmitting component 3 to emit electromagnetic signals of a specific frequency. The magnetoresistive sensor 44 is responsible for continuously detecting and receiving the electromagnetic signals emitted by the geomagnetic signal transmitting component 3 and feeding them back to the second control system 42. The second control system 42 drives the indicator light 45 to flash, thereby reminding tourists. Tourists can move tentatively and observe the flashing changes of the indicator light 45. For example, if they approach rest station 1, the indicator light 45 will flash continuously and at a faster frequency, thus identifying the approximate location of rest station 1. Tourists can return to the main road of the scenic area and find rest station 1 by continuing to move in the direction of the increasing electromagnetic signal, thus achieving self-rescue.

[0057] like Figure 1 and Figure 3As shown, preferably, the self-rescue navigation device for lost tourists in mountainous scenic areas also includes a polarized beam emitter 7. Polarized light has stronger penetrating power in fog and rain / snow than ordinary light, making it easier for tourists to see. The polarized beam emitter 7 is installed on the lifting rod 65 and rotates and moves up and down with the lifting rod 65, thereby expanding the illumination range of the polarized beam emitter 7. This allows the polarized beam to scatter randomly into the external environment or directionally illuminate adjacent rest stations 1 belonging to different self-rescue navigation devices for lost tourists in mountainous scenic areas. The polarized beam emitter 7 is electrically connected to the first control system 5. When the first control system 5 receives a distress signal, it simultaneously drives the polarized beam emitter 7 to emit a polarized beam into the external environment while controlling the geomagnetic emission component to emit an electromagnetic signal. When the tourist approaches to a position where the polarized beam can be seen, it can help the tourist find the rest station 1 more quickly. After the tourist has rested at the rest station 1, the first control system 5 can control the polarized beam emitter 7 to emit a polarized beam into another adjacent rest station 1, allowing the tourist to smoothly reach the next rest station 1 along the beam.

[0058] like Figure 1 and Figure 3 As shown, preferably, there are multiple polarized beam emitters 7, which are distributed at intervals around the axis of the lifting rod 65. The multiple polarized beam emitters 7 form a light-emitting array and can rotate and rise as a whole with the lifting rod 65, thereby increasing the illumination range and intensity of the polarized beam, making it easier for lost tourists to find the rest station 1.

[0059] like Figure 1 and Figure 6As shown, preferably, the self-rescue navigation device for lost tourists in mountainous scenic areas further includes a self-service component 8. The self-service component 8 includes a navigation station 81, a wired telephone 82, and a loudspeaker 83. The navigation station 81 is used for tourists to plan navigation routes. The navigation station 81 is electrically connected to the first control system 5. The navigation station 81 has a first-aid supplies compartment 811, and the door of the first-aid supplies compartment 811 is equipped with a sensor switch 812. The sensor switch 812 is electrically connected to the first control system 5 and the second control system 42. The wired telephone 82 and the loudspeaker 83 are both installed on the navigation station 81. The navigation station 81 has a built-in electronic terminal connected to the first control system 5, allowing tourists to query scenic area maps and plan safe routes. The wired telephone 82 and the loudspeaker 83 are installed on the navigation station 81. The wired telephone 82 allows tourists to call for help from the scenic area authorities when their mobile phone signal is lost. The loudspeaker 83 can play a continuous distress message so that nearby tourists can hear the distress call and receive help quickly. A first-aid supply compartment 811 is located on the side of the navigation station 81. The compartment contains emergency supplies such as medicines and warm clothing. The door of the first-aid supply compartment 811 is equipped with a sensor switch 812. When a tourist wearing a wristband approaches the first-aid supply compartment 811, the sensor switch 812 on the door is triggered by a signal from the second control system 42 within the wristband. This trigger signal is verified by the first control system 5: the first control system 5 identifies the wristband and confirms whether it has sent an active distress signal. Only wristbands verified by the first control system 5 as valid distress signals are authorized to open the door. This verification mechanism ensures that tourists in genuine emergencies can immediately access first-aid supplies, while also effectively preventing unnecessary consumption of these supplies.

[0060] like Figure 1 and Figure 7As shown, preferably, the rest station 1 is provided with multiple roller shutter mechanisms 9, one of which is located at one of the exits of the rest station 1; the roller shutter mechanism 9 includes a third motor 91, a horizontal rotating shaft 92, an insulated curtain 93, and a dustproof shell 94; the third motor 91 is mounted on one of the load-bearing columns of the rest station 1, and is fixedly mounted on the load-bearing column on the exit side; one end of the horizontal rotating shaft 92 is sleeved on the drive shaft of the third motor 91, and the other end of the horizontal rotating shaft 92 is mounted on another load-bearing column of the rest station 1 to rotate with the drive shaft of the third motor 91; one end of the insulated curtain 93 is mounted on the horizontal rotating shaft 92 and rotates with the horizontal rotating shaft 92, so that the insulated curtain 93 can be opened from the exit. The horizontal rotating shaft 92 is lowered or rolled up. The upper end of the heat-insulating curtain 93 is fixedly rolled up on the horizontal rotating shaft 92 and can be lowered or rolled up when the shaft rotates, thereby realizing the opening and closing of the exit. The heat-insulating curtains 93 belonging to multiple different rolling curtain mechanisms 9 are lowered together to separate the rest space of the rest station 1 from the external environment. When the heat-insulating curtains 93 of multiple exits are lowered together under the synchronous control of their respective third motors 91, the internal space of the entire rest station 1 can be effectively isolated from the external environment, playing a role in windproofing and heat preservation. The two ends of the dustproof shell 94 are respectively connected to the two adjacent load-bearing columns of the rest station 1 to be supported by the rest station 1. The dustproof shell 94 is used to cover the horizontal rotating shaft 92 and the heat-insulating curtain 93 to prevent dust from accumulating on the mechanical parts.

[0061] like Figures 1 to 7 As shown, the present invention also provides a method for using a self-rescue navigation device for lost tourists in mountainous scenic areas. The method of using the aforementioned self-rescue navigation device for lost tourists in mountainous scenic areas includes the following steps:

[0062] Step 1: When the thermal imager 22 detects that a tourist has left the main trail and entered an undeveloped area, the first control system 5 sends a signal to the second control system 42, and the second control system 42 controls the vibration motor 43 to vibrate to remind the tourist.

[0063] Step 2: After a tourist gets lost, they press the alarm 41 on the wristband, and the second control system 42 sends an alarm signal to the first control system 5.

[0064] Step 3: The first control system 5 controls the geomagnetic signal transmitting component 3 to transmit a magnetic signal. After receiving the magnetic signal, the magnetoresistive sensor 44 sends a command to the second control system 42. The second control system 42 obtains the straight-line distance between the tourist and the rest station 1 and drives the indicator light 45 to flash.

[0065] Step 4: Tourists move to rest station 1 according to the flashing frequency of indicator light 45. If the tourist is in good health: after planning the movement route in navigation station 81, the first control system 5 drives the polarized light emitter to emit a polarized beam of light to the next rest station 1 on the movement route. Tourists proceed to the next rest station 1 according to the direction of the polarized beam. If the tourist is in poor health: after dialing the wired telephone 82, the tourist waits for rescue on the spot. Tourists can use the wristband to touch the sensor switch 812 to open the first aid supply compartment 811 to obtain first aid supplies, and can close multiple roller shutter mechanisms 9 to maintain body temperature.

[0066] Step 5: After the tourist moves to the corresponding rest stop 1, the polarized light emitter of that rest stop 1 emits a polarized light beam to the next rest stop 1 on the moving route, and so on until the tourist moves to the end of the planned route or the scenic area exit.
