Of course, other data of the drone may be included besides the above description, and the present invention is not limited thereto.
An unmanned aircraft, abbreviated as "drone", and abbreviated in english as "UAV", is an unmanned aircraft that is operated by a radio remote control device and a self-contained program control device, or is operated autonomously, either completely or intermittently, by an onboard computer. The unmanned aerial vehicle is a general name of the unmanned aerial vehicle, is provided with a 4G/5G real-time transmission module, and can transmit longitude and latitude, height, various flight state parameters, videos, shot images and the like back to a background server through a 4G interface in real time or at regular time.
And a background server in the three-dimensional simulation model is used for receiving state information of the unmanned aerial vehicle, recording and storing the state information, and simultaneously storing data of a three-dimensional scene model (environment, tower, weather, unmanned aerial vehicle, no-fly zone and the like). That is to say, in data transmission, not only will convey unmanned aerial vehicle's dynamic information data, still will convey the environmental characteristic data around the unmanned aerial vehicle to drive unmanned aerial vehicle's in the three-dimensional scene motion comprehensively, completely, accurately.
As shown in fig. 3, the latitude, the altitude, various flight state parameters, videos, shot images and the like of the unmanned aerial vehicle can be transmitted back to the background server through the 4G/5G interface in real time or at regular time, data storage is performed by the background data storage server, and a three-dimensional simulation model can be stored in the background data storage server to establish a three-dimensional electronic fence of the unmanned aerial vehicle. In addition, the system can also be arranged on a background visual management and control platform in communication connection with the background server, the background visual management and control platform comprehensively displays the working state of the current unmanned aerial vehicle by calling three-dimensional scene data and information such as states, videos and images of the unmanned aerial vehicle in the background data storage server, and displays the actual effects of the unmanned aerial vehicle routing inspection and the virtual fence through a three-dimensional model. When the unmanned aerial vehicle enters or the distance from the divided no-fly area is within the range of the preset threshold value, the early warning can be realized by the early warning visual terminal, and meanwhile, the early warning information is transmitted to the unmanned aerial vehicle, so that the dynamic fine setting of the no-fly area of the unmanned aerial vehicle is realized, and the remote real-time accurate control is realized.
Finally, step S103 is executed to construct a virtual fence of the unmanned aerial vehicle in real time, so as to partition a three-dimensional no-fly area of the unmanned aerial vehicle.
A virtual fence is a virtual fence that encloses a virtual geographic boundary. Firstly, establishing a two-dimensional no-fly area of the unmanned aerial vehicle based on environmental characteristic data around the unmanned aerial vehicle through a three-dimensional simulation model; and then, a virtual fence of the unmanned aerial vehicle is constructed by combining the three-dimensional running track of the unmanned aerial vehicle, so that the two-dimensional no-fly area is converted into a three-dimensional no-fly area consisting of longitude, latitude and height.
For example, for a transmission tower, deployment information of the transmission tower is scanned first, so that a virtual simulation model and longitude and latitude coordinates which are completely equivalent to the transmission tower are established, and then the coordinates of the unmanned aerial vehicle are reflected to a virtual scene through wireless communication of 4G/5G and the like. After the virtual flight control method is established, a simple or complex flight control area is established by operating in a virtual scene, and then the flight control area is converted into a three-dimensional flight control area consisting of longitude, latitude and height. The converted three-dimensional no-fly areas are transmitted to the unmanned aerial vehicle, and the unmanned aerial vehicle can avoid breaking into the areas in the flying process.
The virtual fence is operated and established on the virtual entity, so that the visualization effect is good, the operation is more intuitive and simple, the required no-fly area is easier to accurately establish, and the dynamic fine setting of the no-fly area is realized. Meanwhile, the real-time flight state of the unmanned aerial vehicle can be reflected in the virtual scene.
The dynamic state means that the three-dimensional simulation scene displayed in the background can be set vividly, and the set three-dimensional closed no-fly area can correspondingly generate corresponding longitude and latitude coordinates and height limits and send the coordinates and the height limits to the unmanned aerial vehicle. Which comprises the following steps: history files are deployed by one key and the setting of stereo closed graphics is defined in a three-dimensional scene (the setting completion can be saved to form the history files).
