[0050] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0051] In Embodiment 1, Figure 1 The implementation process of the hydrogeological monitoring method provided by the embodiment of the present invention is shown, and the details are as follows:

[0052] S100: Define the monitoring area of hydrogeology, obtain the warning task, and send it to the drone. Use the video monitoring device pre-integrated in the drone to collect the video data of the monitoring area, and judge whether there are trapped persons in the monitoring area. If so, record the real-time position of the trapped persons, establish a shouting tracking mechanism, and activate the shouting device pre-integrated in the drone to play the evacuation voice.

[0053] Define the area that needs to be inspected for hydrogeology, that is, the monitoring area. The monitoring area can be a certain river course and dam, etc. Use geographical information data and remote sensing data, and combine factors such as the topography and landform, groundwater distribution and precipitation of the monitoring area to determine the potential risk area and key monitoring points, and integrate and generate a warning task. The warning task is to use the drone to inspect the monitoring area; the warning task includes the flight route of the drone. Send the warning task to the drone. After the drone receives the task instruction, it starts the flight program and enters the monitoring area according to the preset flight route. During the flight, the drone uses the pre-integrated video monitoring device to take real-time pictures of the monitoring area and collect high-definition video data.

[0054] Use the image recognition algorithm pre-embedded in the drone to analyze and process the video data to judge whether there are trapped persons in the monitoring area. The trapped persons refer to the persons moving in the monitoring area; if the drone detects trapped persons, record the real-time position (latitude and longitude coordinates) of the trapped persons; at the same time, activate the shouting device pre-integrated in the drone to play the pre-recorded evacuation voice in a loop; the evacuation voice can be: "You have entered a dangerous area, please transfer to a safe area as soon as possible." In addition, the drone adjusts the flight path according to the moving track of the trapped persons to ensure that the shouting device always covers the trapped persons; the shouting tracking mechanism is: the drone adjusts the flight path and shouts at the trapped persons.

[0055] S200: Activate the shouting tracking mechanism, select a safe area from the monitoring area, generate emergency guidance information, and integrate the emergency guidance information into the evacuation voice.

[0056] Pre-divide a safe area within or near the monitoring area. The terrain of the safe area should be high, with a stable slope, and far from potential landslide or collapse areas. The drone uses the built-in path planning algorithm to provide the optimal evacuation route for the trapped person and generates emergency guidance information accordingly. The emergency guidance information should include the orientation of the safe area, the indication of the evacuation path, and possible obstacles along the way. For example, an emergency guidance information is: "There is a safe area 50 meters ahead of you. Please move forward along the left path and pay attention to avoiding the waterlogged area on the right." Use the drone's loudspeaker device to play the evacuation voice and emergency guidance information.

[0057] S300: After the real-time position coincides with the safe area, pause the shouting and tracking mechanism, use the projection device pre-integrated in the drone to project a direction selection pop-up window onto the ground, and trigger the pre-constructed guidance strategy to obtain the feedback information of the trapped person.

[0058] After the trapped person enters the safe area, pause the follow-up shouting for the trapped person, lower the flight altitude of the drone, and activate the projection device pre-integrated in the drone. Using high-brightness projection or strong-light projection technology, project the direction selection pop-up window directly onto a flat area on the ground or a conspicuous surface object to ensure that the trapped person can clearly see it. The direction selection pop-up window interface indicates different evacuation directions through simple and clear icons and text. While projecting the direction selection pop-up window, activate the emergency guidance strategy in the drone. The emergency guidance strategy is: while pushing the selection pop-up window, play a voice asking the trapped person "Are there any other trapped people nearby? Please point out the direction."

[0059] When the trapped person makes feedback information through waving, body movement or other recognizable actions, the projection device and the video monitoring device work together to capture the feedback signal in real time, analyze the meaning of the action, judge whether there are other trapped people, and determine the corresponding direction.

[0060] S400: Judge whether there is a rescue guidance in the feedback information. If so, based on the rescue guidance, construct a search area and send the search area to the drone to switch the early warning task. If not, continue to execute the early warning task.

[0061] If the feedback information contains the general direction of other trapped people, then generate a rescue guidance based on this general direction. The rescue guidance can be: "There may be trapped people in the southwest direction." With the rescue guidance as the center, preset the side length of the distance to construct a search area, and use the drone to patrol the search area to judge whether there are trapped people. If the feedback information does not contain the general direction of other trapped people, that is, there are no other trapped people nearby or the trapped people are not aware of other situations, then continue to execute the early warning task.

[0062] In Embodiment 2, Figure 2 The implementation process of the hydrogeological monitoring method provided by the embodiment of the present invention is shown. The steps of demarcating the monitoring area of hydrogeology, obtaining an early warning task, and sending it to the unmanned aerial vehicle, and using the video monitoring device pre-integrated in the unmanned aerial vehicle to collect video data of the monitoring area are described in detail as follows:

[0063] S101: Obtain the geographical information image of the monitoring area and draw a monitoring distribution map.

[0064] Obtain the geographical information image of the monitoring area, where the geographical information image includes geographical information data and remote sensing data, and draw a monitoring distribution map. The monitoring distribution map is mainly used to display the geographical information and monitoring data of the monitoring area.

[0065] S102: Select the deployment positions of the sensors and mark the deployment positions on the monitoring distribution map.

[0066] Deploy sensors in the monitoring area, where the sensors are: water level sensors, temperature and humidity sensors, air pressure sensors, infrared detection devices, etc., and mark the deployment positions of the sensors on the monitoring distribution map.

[0067] In Embodiment 3, Figure 3 The implementation process of the hydrogeological monitoring method provided by the embodiment of the present invention is shown. The steps of judging whether there are trapped persons in the monitoring area are described in detail as follows:

[0068] S103: Extract the behavior characteristics of the trapped persons from the video data and compare the behavior characteristics with a feature comparison table, where the feature comparison table consists of abnormal feature items and emergency plan items.

[0069] Through image processing and video analysis techniques, such as action recognition, face recognition, and target tracking, etc., identify the people in the video data and extract key behavior characteristics. These behavior characteristics include the movement patterns, posture changes, and body language of the trapped persons; use the behavior characteristics to query the feature comparison table and judge whether there are the same items in the feature comparison table. If so, it means that the trapped persons have abnormal characteristics, where the abnormal characteristics include rapid movement, long-term stillness, falling, and frequent calls for help, etc.

[0070] S104: Judge whether the trapped persons have abnormal characteristics. If so, activate the corresponding emergency plan.

[0071] If the trapped persons have abnormal characteristics, activate the corresponding emergency plan. The emergency plan can be: sending a distress signal, starting an emergency evacuation procedure, and notifying the rescue team, etc.

[0072] In Embodiment 4,Figure 3 The implementation process of the hydrogeological monitoring method provided by the embodiment of the present invention is shown. The following details the step of selecting a safe area from the monitoring area and generating emergency guidance information, as follows:

[0073] S201: Generate a direction guide via the real-time position and the safe area, and send the direction guide to the projection device.

[0074] Calculate the best path from the current position of the trapped person to the safe area, and dynamically adjust the path according to the real-time situation, such as avoiding obstacles, selecting the shortest or safest route, etc.; generate a direction guide, and use the projection device to project the direction guide onto the ground.

[0075] S202: Define the real-time position as the flight end point of the drone. When the flight end point, the real-time position, and the safe area coincide, activate the projection device.

[0076] It should be noted that when the trapped person reaches the flat area in the safe area and the position of the drone coincides with that of the trapped person, start the projection device for projection.

[0077] In Embodiment 5, Figure 4 The implementation process of the hydrogeological monitoring method provided by the embodiment of the present invention is shown. The following details the step of determining whether there is a rescue guide in the feedback information. If so, construct a search area based on the rescue guide, as follows:

[0078] S401: Determine the search boundary and configure the influencing factors of the search boundary, where the influencing factors at least include: terrain, drone endurance, and weather.

[0079] According to the terrain of the monitoring area, the cruising ability of the drone, and the local weather, etc., delimit the search boundary of the drone.

[0080] S402: Integrate the search boundary to generate a search area.

[0081] Define the area enclosed by the search boundary as the search area, send the search area to the drone pilot, and let him fine-tune the search area.

[0082] In Embodiment 6, different from Embodiment 1, in the embodiment of the present invention, the guidance strategy is: in the direction selection pop-up window, identify several options, mark the projection positions of each option, and when the real-time position coincides with the projection position, generate a target option and fill it into a preset template to generate feedback information.

[0083] Set multiple options in the direction selection pop-up window. The options can be several direction arrows. After the trapped person reaches the flat area in the safe zone, find the projection position near the trapped person and control the drone to fly to the projection position. The drone uses a loudspeaker to direct the trapped person to make a choice, determines the choice result as the target option, and generates feedback information using the target option and a template, where the template is pre-established by professionals.

[0084] For example, after the trapped person reaches the safe zone, the drone projects multiple direction arrows near the trapped person and shouts through the loudspeaker: "Are there any other trapped people nearby? If so, please stand on the corresponding arrow." If it is determined through an image recognition algorithm that there are trapped people standing on the arrow corresponding to the northeast direction, then the northeast direction arrow is the target option, and through the corresponding digital option, the feedback information is determined to be: There are at least 3 trapped people in the northeast direction.

[0085] In the above process, a dialogue can also be established between the drone and the trapped person through methods such as digital selection and graphic selection to obtain more rescue intelligence.

[0086] In Embodiment 7, different from Embodiment 1, in the embodiment of the present invention, the method further includes:

[0087] Using the sensor, collect the monitoring data at the deployment position and create a fluctuation range corresponding to the deployment position one by one;

[0088] When the monitoring data exceeds the fluctuation range, define the corresponding deployment position as a potential hazard point, integrate all potential hazard points, and generate a warning task.

[0089] According to the position, time, environment, etc. of each sensor, configure a fluctuation range for each sensor. In other words, under normal circumstances, the monitoring data of the sensor will vary within the fluctuation range. For example, for a certain small river channel, according to historical water level data, its water level is generally between 0 and 30 centimeters, so the fluctuation range is 0 - 30 centimeters. If the monitoring data on a certain day exceeds the fluctuation range, then define the deployment position as a potential hazard point, insert the potential hazard point into the flight route in the warning task, and update the flight route, and use the drone to conduct inspections on the potential hazard points.
