[0002] As the urbanization process continues to accelerate, a large number of people are pouring into cities, resulting in a rapid expansion of urban areas, while the construction of urban infrastructure often fails to keep up with this pace, especially in terms of drainage systems. At the same time, the number of extreme weather events caused by global climate change is increasing, and heavy rains are frequent, making urban rainstorm disasters a problem that cannot be ignored.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The following describes a regional rain and flood detection and prevention vehicle and method according to an embodiment of the present invention with reference to the accompanying drawings.

[0031] Figure 1 It is a schematic structural diagram of a regional rain and flood detection and prevention vehicle 10 provided in an embodiment of the present invention.

[0032] like Figure 1-4 As shown, the regional rain and flood monitoring and prevention vehicle 100 includes: a vehicle body 1, a first collection component 2, a monitoring component 3, a fusion component 4 and a control component 5.

[0033] Among them, the first acquisition component 2 arranged on the vehicle body 1 is used to perform point cloud scanning on the target area to obtain the first terrain data of the target area and collect the first rain and waterlogging video of the target area when the environment in which the vehicle is located meets the preset conditions. The monitoring component 3 arranged on the vehicle body 1 is used to monitor the dynamics of human flow and water flow in the target area. The fusion component 4 arranged on the vehicle body 1 is used to fuse the first terrain data, the first rain and waterlogging video, the dynamics of human flow and the dynamics of water flow to generate a rain and waterlogging model, and generate a control instruction for at least one valve of the drainage system of the target area when rain and waterlogging occurs in the rain and waterlogging model. The control component 5 is arranged on each valve in the target area, and the control component 5 is provided with a PCL system, which is used to control at least one valve to perform a corresponding control action based on the control instruction of at least one valve.

[0034] In some embodiments, a driver's seat is provided inside the vehicle body 1, equipped with a high-precision navigation and positioning system for driving and collecting data, equipped with necessary control and operation interfaces, equipped with all-weather adaptability and all-terrain driving capabilities, to ensure normal operation under various weather and terrain conditions.

[0035] In some embodiments, the first acquisition component 2 includes a first laser radar device and a second image acquisition device, wherein the first laser radar device is used to perform high-precision point cloud scanning of the surface elevation, riverbed, rainwater outlet and other landforms of the target area when the environment in which the vehicle is located meets the preset conditions, so as to obtain the first terrain data of the target area including the location of the drainage outlet and other terrain data. The range of the target area can be 200 meters, which is used for model assimilation and analysis. The second image acquisition device can be equipped with an optical high-definition camera and / or an infrared high-definition camera to monitor the rain and waterlogging conditions of the target area in real time through video recording, that is, to collect the first rain and waterlogging video including the flooding range and other flooding conditions. The preset condition is an area with flat terrain that can be reached by the vehicle.

[0036] In some embodiments, it also includes: a second acquisition component 6 arranged on the vehicle body, the second acquisition component includes at least one drone, wherein at least one drone is provided with a second laser radar device and a second image acquisition device, when the environment in which the vehicle is located does not meet the preset conditions, that is, the vehicle is in an area with complex terrain or difficult for the vehicle to reach, the drone carries the second laser radar device and the second image acquisition device to perform high-precision terrain and surface image survey, so as to collect second terrain data including terrain data such as the location of the drainage outlet in the target area, and collects a second rain and flood video including flooding conditions such as the flooding range in the target area, so that the fusion component obtains fusion data. Among them, the second image acquisition device can be equipped with a laser radar device, an optical high-definition camera and / or an infrared high-definition camera.

[0037] Furthermore, the drone can be a vertical take-off and landing fixed-wing drone or a multi-rotor drone equipped with a lidar and a high-resolution camera. After the drone takes off, the lidar is used to scan the terrain, and the high-resolution camera is used to collect surface images. The second terrain data and the second rain and waterlogging video collected by the drone are transmitted to the fusion component 4 through the communication component 7 to be integrated with the first terrain data, the first rain and waterlogging video, the dynamics of people flow and the dynamics of water flow.

[0038] In some embodiments, the monitoring component 3 integrates other sensors such as a water depth meter, a meteorological sensor, a water level sensor, and a flow sensor, which can be set on the front bumper of the vehicle body 1 to monitor environmental conditions, human flow dynamics, water flow dynamics, and submerged water depth in real time during the vehicle's driving and stationary state. In addition, the fusion component 4 can assist in flood analysis and early warning release based on environmental conditions, human flow dynamics, water flow dynamics, and submerged water depth.

[0039] In some embodiments, Figure 6As shown, the fusion component 4 first cleans the collected first terrain data, the second terrain data, the first rain and waterlogging video, the second rain and waterlogging video and other sensor data, that is, performs noise filtering and point cloud alignment on the point cloud terrain data to ensure high data accuracy, performs image processing and object detection on the video data, identifies key features of water flow dynamics and human flow dynamics based on a preset recognition algorithm, and extracts key ground feature information such as drain outlets and rain grates; uses multi-source data fusion technology to fuse the processed data to generate a rain and waterlogging model, and then generates control instructions for at least one valve of the drainage system in the target area when rain and waterlogging occurs in the rain and waterlogging model.

[0040] Furthermore, each valve in the target area is also provided with a measuring device. After the control component 5 executes the corresponding control instruction, the measuring device will feed back the real-time drainage situation of the valve position to the fusion component 4, and the fusion component 4 will update the rain and waterlogging model to realize the digital twin. When the rain and waterlogging model shows that the drainage speed and water depth of the opened valve cannot solve the current rain and waterlogging situation, a new control instruction for at least one valve is regenerated based on the preset control algorithm, multiple valves are opened or the originally opened valve is opened at a larger angle, thereby realizing flexible control. When the rain and waterlogging model shows that the drainage speed and water depth of the opened valve do not reach the preset value, a water outlet cleaning warning or cleaning instruction is issued, and the staff will perform manual cleaning according to the warning situation, or control the relevant cleaning tools to clean up, so as to solve the problem of garbage in the drainage outlet slowing down the drainage speed, thereby preventing the flood situation from becoming more serious.

[0041] In some embodiments, Figure 1-5 As shown, a lifting platform 13 is arranged on the top of the vehicle body, so as to help the first acquisition component 2 to collect clearer first terrain data by lifting; a display component 12 is arranged on the tailgate of the vehicle body 1 to display the rain and waterlogging model; at least one landing and take-off platform 11 for a UAV is arranged inside the vehicle body, and after the tailgate of the vehicle body 1 is opened, the landing and take-off platform 11 for the UAV to be taken off can be pulled out to assist the UAV to take off; a storage space 14 is arranged under the landing and take-off platform 11 to place the fusion component 4 and the control component 5 to store related cleaning tools, such as a vehicle-mounted cleaning robot, which cleans the blockage at the opened valve after receiving the cleaning instruction issued by the rain and waterlogging model, and a power supply interface can also be arranged in the storage space 14 to charge the cleaning tools.

[0042] In some embodiments, Figure 1-5As shown, it also includes: a communication component 7 and a power supply component 8, wherein the communication component 7 can realize high-speed data transmission and remote control to ensure the real-time and high efficiency of the system, and the power supply component 8 can power various components of the regional rain and flood measurement and prevention vehicle 100. Among them, the communication component 7 may include 5G communication equipment and a tethered drone relay system, and the 5G communication equipment is used to transmit data at high speed, that is, the first terrain data, urban rain and flood video, human flow dynamics and water flow dynamics are transmitted to the fusion component 4. At the same time, the 5G communication equipment transmits the valve command to the control component 5 to ensure that the real-time transmission of data and the issuance of control commands can be achieved in areas with complex terrain, and the real-time drainage conditions measured by the measuring equipment are fed back to the fusion component 4, so that the fusion component 4 updates the rain and flood model and issues new control commands in time. The tethered drone relay system transmits the second terrain data to the fusion component 4.

[0043] In summary, the regional rain and flood monitoring and prevention vehicle proposed in the embodiment of the present invention realizes all-weather, all-terrain and high-precision data collection through a mobile monitoring and prevention vehicle, realizes the rapid collection of terrain, images and videos; performs intelligent analysis and processing on the collected data; uses communication components to remotely control valves, optimizes the operation of the drainage system, and improves the city's ability to cope with rain and flood disasters; in addition, it can also issue accurate early warning information to improve emergency response efficiency.

[0044] Next, the regional rainwater flooding detection and prevention method proposed in accordance with an embodiment of the present invention will be described with reference to the accompanying drawings.

[0045] Figure 7 A schematic flow chart of a method for regional rainwater flooding detection and prevention provided in an embodiment of the present invention.

[0046] like Figure 7 As shown, the method for rainwater flooding detection and prevention in this area includes the following steps:

[0047] In step S701, during the driving process, a point cloud scan is performed on the target area to obtain first terrain data of the target area, and a first rain and waterlogging video of the target area is collected.

[0048] Specifically, during the driving process of the survey and defense vehicle, the first acquisition component is used to perform high-precision scanning of surface elevations, rainwater outlets and other ground features, wherein the laser radar equipment is used to generate accurate point cloud data, namely the first terrain data, and the high-definition camera can capture real-time video of the road, rainwater outlet and the surrounding environment, thereby obtaining the first rain and waterlogging video, and the first terrain data and the first rain and waterlogging video are transmitted to the fusion component through the communication component.

[0049] If the target area has complex terrain or is difficult for vehicles to reach, a drone carrying a second lidar device and a second image acquisition device is used to conduct high-precision terrain and surface image surveys to collect second terrain data of the target area and a second rain and waterlogging video of the target area, and the second terrain data and the second rain and waterlogging video are transmitted to the fusion component through the communication component.

[0050] In step S702, the water flow dynamics in the target area are monitored.

[0051] Specifically, a monitoring component that integrates meteorological sensors, water level sensors, and flow sensors is used to monitor environmental conditions and water flow dynamics in real time, and transmit the data to the fusion component.

[0052] In step S703, the first terrain data, the first flooding video and the water flow dynamics are integrated to generate a flooding model, and when flooding occurs in the flooding model, a control instruction for at least one valve of the drainage system of the target area is generated.

[0053] Specifically, the fusion component is used to clean the first terrain data, the first rain and flood video, the human flow dynamics and the water flow dynamics and even the second terrain data and the second rain and flood video, that is, the point cloud terrain data is noise filtered and the point cloud is aligned to ensure the high accuracy of the data, the video data is subjected to image processing and object detection, the key features of the water flow dynamics and the human flow dynamics are identified, and the key ground feature information such as rain grates is extracted; the processed data is fused using multi-source data fusion technology to generate a rain and flood model, and then, when rain and flood occur in the rain and flood model, a control instruction for at least one valve of the drainage system in the target area is generated.

[0054] In step S704, at least one valve is controlled to perform a corresponding control action based on the control instruction of at least one valve.

[0055] Specifically, the communication component receives control instructions from the fusion component and sends the control instructions to the valve control system, which adjusts the opening angle of the corresponding valve to ensure that the drainage system operates efficiently under different rain and flood conditions. In addition, through the feedback loop, the execution status and drainage effect of the real-time monitoring valve are fed back to the fusion component, and the valve opening angle is adjusted when necessary to optimize the overall performance of the drainage system.

[0056] It should be noted that the aforementioned explanation of the embodiment of the regional rain and flood measurement and prevention vehicle is also applicable to the regional rain and flood measurement and prevention method of this embodiment, and will not be repeated here.

[0057] According to the regional rain and waterlogging measurement and prevention method proposed in an embodiment of the present invention, all-weather, all-terrain and high-precision data collection is realized through a mobile measurement and prevention vehicle, and the rapid collection of terrain, images and videos is realized; the collected data is intelligently analyzed and processed; the valves are remotely controlled by using communication components, the operation of the drainage system is optimized, and the ability of the city to cope with rain and waterlogging disasters is improved; in addition, accurate early warning information can also be issued to improve the efficiency of emergency response.
