The invention provides a high-precision unmanned aerial vehicle positioning system based on an RTK technology, and the system comprises a positioning service platform which is based on a CORS network system structure, builds a differential information calculation model, calculates high-precision differential data, transmits the differential number to an operation unmanned aerial vehicle through a wireless communication data link, processes the carrier phases of two measurement stations in real time, the carrier phase is sent to the operation unmanned aerial vehicle, difference calculation is carried out to calculate coordinates, and then accurate positioning of the operation unmanned aerial vehicle is achieved; and the unmanned aerial vehicle control terminal acquires image information and air gas parameters of the airspace meteorological environment through which the operation unmanned aerial vehicle passes in real time, performs data analysis and processing, and plans an operation unmanned aerial vehicle inspection scheme based on the micro-meteorological prediction information of the plurality of inspection paths. According to the invention, the meteorological environment of the airspace through which the pilot line operation unmanned aerial vehicle passes is analyzed in real time, and the unmanned aerial vehicle inspection scheme is intelligently planned based on the micro-meteorological prediction information of multiple inspection paths, so that the autonomous inspection work of the unmanned aerial vehicle is realized.
Description
technical field [0001] The invention relates to the technical field of drone control, in particular to an RTK technology-based high-precision positioning system for drones. Background technique [0002] As an important part of the power grid, the distribution network is an important link between the large-scale transmission network and the drone. The safe and reliable operation of the system directly affects the normal operation of the entire power grid system and the daily production and life of users. It is the basis to ensure the safety of power supply to carry out regular inspections on the distribution network lines, and to know and master the operation of the distribution lines and the changes in the surrounding environment and line protection areas at any time. [0003] The distribution network refers to the power network that receives electric energy from the transmission network or regional power plants, and distributes it locally through power distribution faciliti...
