BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Figure 1 This is a flow chart of the Beidou-based field personnel positioning and communication method provided by the present invention. DETAILED DESCRIPTION

[0031] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0032] Embodiment 1

[0033] like Figure 1 As shown, the present invention provides a preferred embodiment, a field personnel positioning and communication method based on Beidou, comprising:

[0034] Step S1, obtaining the location data information collected by the user's first terminal positioning device through the Beidou short message satellite, and analyzing the user's current location based on the location data information, and displaying it on the background data large screen in combination with the GIS map; and judging whether the user is in a dangerous area based on the location data information, and then sending a warning notification to the user's first terminal positioning device when the user is in a dangerous area.

[0035] Among them, the user in this embodiment refers to a field personnel who are engaged in outdoor adventure tourism and is a registered user of the system. The present invention is applied to the positioning monitoring of users such as outdoor hiking, self-driving, and cycling. By positioning the user, the user's location is obtained, and then when the user is in danger, the user is notified and rescued in time to ensure the user's personal safety. Specifically, this embodiment configures a first terminal positioning device for each user to achieve user positioning, and uploads data to the background monitoring platform through the Beidou short message satellite, and the background monitoring platform monitors the user based on the received data. This embodiment realizes data communication through satellites, which can improve communication stability to solve the problem of no mobile network signals in remote areas.

[0036] Furthermore, the system of this embodiment also provides a background monitoring platform, through which the received data is analyzed to realize the positioning of the user. That is, by receiving the location data information of the first terminal positioning device carried by the user and analyzing it to obtain the current location of the user, and then combining it with the GIS map, it is possible to monitor each user, that is, to display the user on the map, and display it on the background data screen, so that the background management user can clearly see the real-time location of each user. Once a user needs rescue, rescue can be quickly realized through real-time positioning of the user. Among them, the current location of the user includes information such as latitude, longitude and altitude.

[0037] Furthermore, after obtaining the user location data information, the present invention can also determine whether the user has entered a dangerous area according to the user's current location, and mark the user in the GIS map with different colors according to the judgment result. Through the marking of different colors, the management user of the background monitoring platform can clearly observe which users are likely to be in danger, focus on them, and carry out rescue in time.

[0038] Among them, the dangerous area refers to an area where danger may occur, which can be set by the back-end management user according to the national geographic information and the area where accidents or rescue events occurred stored in the system. For example, if accidents or rescue signals often occur in a certain area, it means that the area is more dangerous, and the area can be set as a dangerous area. Similarly, for some undeveloped areas in some countries, it can be obtained according to the national geographic information that these areas have unknown dangers and can also be set as dangerous areas. Furthermore, for some areas involving national security or other prohibited areas, they can also be set as dangerous areas for confidentiality and prohibit users from entering. The above-mentioned dangerous areas can be marked on the GIS map by the back-end monitoring platform, such as marking with a box or a circular area, or setting a virtual line. When it is necessary to add a dangerous area or delete a dangerous area, the management user of the back-end monitoring platform can perform a region division operation on the GIS map, or divide the area by entering the longitude and latitude coordinates. For example, for different seasons or different regions, the degree of danger of the area involved in the movement will be different. Therefore, the above-mentioned dangerous areas can be flexibly set according to the actual situation. At the same time, the danger level of each dangerous area is divided, and each dangerous area has a corresponding longitude and latitude range; at the same time, different warning notification contents and warning notification strategies are set for dangerous areas of different danger levels. In this way, when the user's current location is obtained, it is matched with the longitude and latitude range of the dangerous area constructed in the system to determine whether the user is in a dangerous area and the danger level of the dangerous area, and then the corresponding warning notification content is generated according to the corresponding danger level and sent to the user's first terminal positioning device according to the warning notification strategy.

[0039] For example, this embodiment can also be set as a first-level dangerous area, a second-level dangerous area, and a third-level dangerous area according to the degree of danger, and the danger level increases step by step. When it is determined that the user is in a first-level dangerous area according to the user's current location, a warning notification can be generated and sent to the user's first terminal positioning device to remind the user to pay attention to safety and stay away from the dangerous area as soon as possible.

[0040] When the user is in a secondary danger zone, warning notifications may be continuously sent to the user's first terminal positioning device to remind the user to stay away from the area until the user leaves the corresponding danger zone and stops sending warning notifications to the user's first terminal positioning device.

[0041] When the user is in a level 3 danger zone, while continuously sending warning notifications to the user's first terminal positioning device, the system also provides the user with the fastest movement route away from the danger zone, and starts the timing function at the same time; once the timing time exceeds the timing time, if the user is still in the danger zone, the user may be in danger, and the optimal rescue strategy can be matched for the user according to the user's current location to implement the rescue of the user, such as notifying the corresponding rescue team or supervision team to rescue the user or taking other measures to force the user to leave.

[0042] The present invention monitors the user's position in real time so as to promptly rescue the user who is in danger or needs rescue. At the same time, the user's position can be obtained in time during the rescue, thereby improving the rescue efficiency and success rate.

[0043] Preferably, the first terminal positioning device in the present embodiment has a built-in satellite communication module, which can be communicated with the Beidou short message satellite, and then communicated with the background monitoring platform to realize data interaction. The Beidou short message satellite is used to realize monitoring of users, so as to solve the problem in the prior art that emergency communication cannot be carried out when there is no mobile signal due to poor signal outdoors. The present invention realizes real-time positioning by using satellite communication, so as to monitor people in the wild. Once they encounter danger, they can send out a distress signal in time. At the same time, rescue personnel can also quickly locate the user according to the positioning data in the distress signal, and launch rescue in time.

[0044] More specifically, according to different modes of travel, the first terminal positioning device can be divided into the following types: When the mode of travel is hiking or cycling, the first terminal positioning device may include a Beidou short message portable terminal and a smart watch, or a Beidou short message handheld mobile terminal. That is, when using a smart watch, the smart watch can be paired with the Beidou short message portable terminal, and the user can carry the Beidou short message portable terminal and wear a smart watch at the same time, and connect the Beidou short message portable terminal to the smart watch using Bluetooth communication. Among them, the smart watch is installed with a corresponding APP to provide data interaction with the user to obtain the user's location information; at the same time, in addition to the user's location information, the smart watch can also monitor other information of the user, such as obtaining the user's hiking time, hiking mileage, hiking time and the user's physical health information. The user's physical health information includes heart rate, breathing, calorie consumption and other data, which are specifically displayed in real time through the display screen of the smart watch. The smart watch is also connected to the Beidou short message portable terminal via Bluetooth communication to send the acquired user location information to the Beidou short message portable terminal, which then generates short message data from the acquired user location information and uploads it to the Beidou short message satellite, which then uploads the user location information to the system's background monitoring platform via the Beidou short message satellite. When using it, the user can wear the smart watch on the wrist, connect the Beidou short message portable terminal to the smart watch via Bluetooth, and place the Beidou short message portable terminal in a pocket or hang it on a clothes pocket or backpack.

[0045] Similarly, the first terminal positioning device can be a Beidou short message handheld mobile terminal, which can be held by the user or installed on a riding vehicle, etc. The Beidou short message handheld mobile terminal is provided with a satellite communication module and a positioning module to realize the positioning of the user and upload the positioning data to the Beidou short message satellite, and then upload it to the background monitoring platform. The Beidou short message handheld mobile terminal is equivalent to an integrated all-in-one machine that integrates a smart watch and a Beidou short message portable terminal. In this way, the user only needs to carry one device to realize positioning and communication. Of course, according to the actual situation, other modules can also be set inside the Beidou short message first terminal positioning device to realize the corresponding functions, such as recording the user's hiking mileage, usage time, usage time, etc., and displaying it to the user through the display screen of the Beidou short message first terminal positioning device.

[0046] Similarly, when the user's mode of travel is self-driving, the first terminal positioning device can be a vehicle-mounted Beidou short message terminal device, which is applied to vehicle-mounted equipment. For example, for users traveling outdoors by car, it is installed in the car to locate the car and thus the user. While locating the vehicle through the Beidou short message vehicle-mounted terminal, it is also connected to the vehicle system to obtain the vehicle's operating information for vehicle navigation, etc.

[0047] Step S2, regularly generating a user motion trajectory according to the location data information obtained in the system and sending the user motion trajectory to the user's first terminal positioning device through the Beidou short message satellite, and displaying the motion trajectory to the user through the display screen of the first terminal positioning device when the user views the motion trajectory through the first terminal positioning device.

[0048] Specifically, in this embodiment, the user motion trajectory is generated at a fixed time, and each time the user motion trajectory is generated, it refers to the motion trajectory generated according to the user location information obtained within a preset time period, and it is not the entire motion trajectory of the user after starting the device. Since the user's hiking, driving, cycling, etc. take a long time, the amount of data of the acquired user location information will gradually increase as time goes by. If the user motion trajectory is generated according to all the user location information each time, it will cause the system performance to decline. Therefore, this embodiment sets a timing time in the system. Whenever the timing time reaches the preset time, the user's motion trajectory within the timing time period is generated according to the user location information obtained within the timing time period, and then the motion trajectory is sent to the first terminal positioning device; at the same time, the timing time is reset to zero and restarted.

[0049] In addition, when the first terminal positioning device receives a new motion trajectory, the newly acquired motion trajectory is spliced ​​with the user motion trajectory stored in the device to form the user's complete motion trajectory. In this way, each time the generated new motion trajectory is spliced ​​with the original motion trajectory that has been generated to obtain a complete motion trajectory, avoiding the problem of system performance degradation due to excessive data volume when all user location information is required to generate a motion trajectory each time.

[0050] Step S3: predict the area that the user will pass through in the future in real time based on the location data information and the user's expected destination, and then make an early warning judgment based on the weather conditions of the area that the user will pass through in the future, and generate an early warning signal based on the early warning judgment result and send it to the user's first terminal positioning device via the Beidou short message satellite to remind the user.

[0051] Specifically, when predicting the area that the user will pass through in the future, the location data information is used as the user's starting point, and multiple planned routes are matched from the system in combination with the user's expected destination and travel mode. An optimal planned route is selected from the multiple planned routes according to the preset matching rules, and the optimal planned route is used as the user's future movement route, and then the area that the user will pass through in the future is obtained based on the user's future movement route. In this way, an early warning broadcast can be made based on the weather conditions of the area that the user will pass through in the future, so as to remind the user in time and make plans in advance, such as resting on the spot or accurately equipping.

[0052] In addition, when selecting the optimal planned route for the user, matching is performed according to the preset matching rules. The preset matching rules refer to setting multiple influencing factors in advance, setting scores for each influencing factor, and then scoring each planned route according to the influencing factor of each planned route to obtain the total score of each planned route, and then selecting a planned route from multiple planned routes as the optimal planned route according to the total score of each planned route. Among them, the planned route refers to the planned route between the starting point and the destination stored in the system. The system can collect each user's motion trajectory generated historically to obtain the planned route between the starting point and the destination, and then match the user to obtain the optimal planned route, provide navigation for the user, and also obtain the area that the user will pass through in the future according to the planned route, and then warn the weather conditions of the area that the user will pass through in the future to remind the user to make accurate decisions in advance. Among them, the influencing factors include user information, such as gender, age, travel mode, number of travelers, whether there are rest points along the way according to the weather conditions, the number of rest points along the way, the travel speed, the historical travel duration, etc., and set the corresponding weight for each influencing factor, and set a scoring table for each influencing factor. The influencing factors of each planned route are scored through a scoring table, and then the total score of each planned route is calculated by weighted average. Then, the optimal planned route is selected as the user's planned route based on the total score, and the user is navigated according to the planned route. At the same time, the area that the user will pass through in the future can be obtained. In addition, for the above-mentioned planned routes, when the travel mode selected by the user is different, the planned routes obtained are also different.

[0053] Preferably, in order to facilitate rescue, the first terminal positioning device in this embodiment is also provided with a one-key rescue function. Specifically, a corresponding one-key rescue button can be provided on the first terminal positioning device, and once the user has an accident and needs rescue, a one-key rescue signal can be sent through the one-key rescue button.

[0054] That is, the present invention also includes: step S4, when obtaining the one-key rescue signal of the first terminal positioning device, parsing the one-key rescue signal to obtain the current location of the user, generating a rescue notification in combination with the user information, and sending the rescue notification to the corresponding rescue department to take corresponding rescue measures.

[0055] When a user needs rescue, he can send a rescue signal through the first terminal positioning device he carries. When the rescue signal is turned on, the user's location data information will also be uploaded so that the background monitoring platform can parse the user's current location and start rescue. At the same time, during the rescue, the user is matched with a corresponding rescue team based on the user's current location and user information, and a rescue notification is sent to the corresponding rescue team so that the corresponding rescue team can rescue the user. Specifically, for example, the user's current location is matched with the rescue team closest to the user, so that rescue can be carried out in time to ensure the efficiency and success rate of the rescue.

[0056] At the same time, in order to further improve the rescue success rate, this embodiment can also obtain the safe shelter closest to the user and the route from the user's current location to the safe shelter closest to the user according to the user's current location, and send them to the user's first terminal positioning device to remind the user to arrive at the corresponding safe shelter in time to wait for rescue. For example, for some people who can move, they can arrive at the safe shelter in time to wait for rescue to avoid further injury or attack by other animals.

[0057] In addition, to assist in rescue, when a one-button rescue signal is obtained from the first terminal positioning device, a satellite remote sensing image within a preset range is obtained through the user's current location, and the environmental information of the user's current location, such as vegetation, forest, terrain and other information, is obtained based on the satellite remote sensing image within the preset range. At the same time, the weather conditions at the user's location can also be obtained, and then the environmental information, weather conditions, user information and the user's current location of the user are combined to generate a rescue notification to assist in rescue.

[0058] Preferably, this embodiment also includes: when obtaining a one-button rescue signal from the second terminal positioning device, video data or recording data sent by the second terminal positioning device is also obtained, and then a corresponding rescue strategy is generated according to the installation position of the second terminal positioning device, video data or recording data, and corresponding measures will be taken according to the corresponding rescue strategy.

[0059] Among them, the second terminal positioning device refers to a positioning device fixed in the wild, which includes a main control module, a camera module or a recording module, a positioning module, and a satellite communication module. The main control module is connected to the Beidou short message satellite communication through the satellite communication module, and then communicated with the background monitoring platform to realize data interaction. The main control module is also electrically connected to the positioning module, the camera module or the recording module, and is used to obtain the location information of the second terminal positioning device through the positioning module when the one-key rescue is started, and to record the surrounding environment of the second terminal positioning device through the camera module or record the recording data of the user waiting for rescue through the recording module, and then upload the location information, video data or recording data to the background monitoring platform through the Beidou short message satellite, and the background monitoring platform will generate a rescue strategy in time according to the above data, and then rescue the user in time. That is, this embodiment not only provides users with a movable first terminal positioning device to realize the positioning and communication of personnel, but also sets a fixed second terminal positioning device to deal with emergencies. For example, when the user's first terminal positioning device is out of power or damaged, the user can use the second terminal positioning device set nearby to achieve one-key rescue. At the same time, it can also be used for users who do not have the first terminal positioning device when they need rescue, and the fixed second terminal positioning device can be used to supplement the user's positioning to ensure the efficiency and success rate of rescue.

[0060] Specifically, the second terminal positioning device can be a Beidou call post located in the wild. When the user encounters danger, he can use the Beidou call post in the wild to realize a one-button alarm and a help function. At the same time, when the one-button alarm is activated, the second terminal positioning device activates the camera module or the recording module to record or record the surrounding environment of the terminal device, and at the same time obtains the location information of the second terminal positioning device by activating the positioning module, and then uploads it to the background monitoring platform through the Beidou short message satellite. The background monitoring platform matches the rescue strategy to provide rescue guidance for the rescue department and improve the rescue efficiency and success rate.

[0061] The present invention can also realize teamwork. For example, users can build groups or search and join nearby groups. In this way, they can report their location in the group in time so that when problems occur, nearby users can provide timely rescue.

[0062] Specifically, the present invention also includes: obtaining a group building request from a first terminal positioning device carried by a user, building a group according to the group building request, and using the first terminal positioning device carried by the user as the master device of the group, while generating a group QR code and sending the group QR code to the master device of the group, so that the corresponding second terminal positioning device can scan the group QR code to join the group. The master device of the group is generally the first terminal positioning device that initiates the group building request.

[0063] When the first terminal positioning device serving as the main device of the group receives the group QR code, it can display the group QR code to other users, so that other users can join the group by scanning the above group QR code through their own first terminal positioning devices, and share their own positioning information with the group, so as to share the location information of the soft members.

[0064] When the system obtains the one-key rescue signal of the first terminal positioning device, it also determines whether the first terminal positioning device is associated with a group. If so, it matches the group where the first terminal positioning device belongs to, and sends the one-key rescue signal to each first terminal positioning device in the group where the first terminal positioning device belongs to via the Beidou short message satellite. In this way, the demand for nearby rescue and rapid rescue can be met.

[0065] Of course, users can also automatically join nearby groups. Specifically, the user initiates a group joining request through his own first terminal positioning device, and the system will match the best group for the user based on the user's location information and user information, and join the corresponding group.

A microphone or a recording module is provided in the first terminal positioning device to realize the intercom function. Specifically, when an intercom request signal of the first terminal positioning device is obtained and the first terminal positioning device is associated with a group, the intercom request signal is sent to each first terminal positioning device in the group to establish an intercom communication between the first terminal positioning device and each first terminal positioning device in the group, thereby realizing the intercom function within the group.

[0067] Similarly, the intercom function of nearby personnel can also be realized. When the intercom request signal of the first terminal positioning device is obtained, the first terminal positioning device within the preset range of the first terminal positioning device is searched according to the location data information of the first terminal positioning device, so as to send the intercom request signal to each first terminal positioning device within the preset range, so as to establish intercom communication between the first terminal positioning device and each first terminal positioning device within the preset range. Similarly, through the intercom function, intercom can be realized with nearby travelers to achieve rescue.

[0068] The present invention applies Beidou short message satellites to user monitoring and communication, thereby achieving monitoring and communication of users even when people in the wild use ordinary mobile phones with unstable or no signals. It also achieves monitoring of users in danger, and timely rescue of teams in need of rescue. At the same time, data support is provided for the rescue, thereby improving the efficiency and success rate of the rescue, and also ensuring the safety of the rescuers.

[0069] More preferably, the present invention further includes: an experience feedback step, that is, after the user uses the device, the user is provided with a user experience feedback form to collect the user's travel experience, and after extracting key data according to preset keywords, the user's motion trajectory is scored in combination with a preset scoring mechanism, so that the system can obtain several optimal travel motion routes based on the scores of multiple users' motion trajectories through comprehensive analysis to recommend them to the user. Specifically, by collecting the user's travel experience and combining machine learning and artificial intelligence and other technologies for big data analysis, the user's experience data can be reused to provide it to other users. For example, the user's historical motion trajectory, departure starting point, expected destination, and rest point on the way, as well as usage data, can be uploaded to the system, and the system can use it for other users based on the usage data of each user, such as recommending a motion route for the user, recommending a departure starting point, and recommending a destination. Furthermore, the present invention can also extract key data for determining the optimal route based on the set keywords, and score the user's motion trajectory. Then the system can obtain several optimal travel motion routes based on the scores of multiple users' motion trajectories through comprehensive analysis to recommend them to the user, and can be fed back to the user through the feedback platform, and the user can choose the corresponding motion route for travel adventure according to his own situation.
