The invention discloses a co-frequency encryption digitalized communication transmission control system for multiple sets of airborne equipment of an unmanned plane. The co-frequency encryption digitalized communication transmission control system comprises an airborne end control system and a ground end control system, wherein the airborne end control system comprises a first digital wireless encryption transmission module, a real-time access matching module, a share access servo module, a share access matching module and an audio / video encoding module; the ground end control system comprises a second digital wireless encryption transmission module, an audio / video decoding module, an image system, a flying operation system and an airborne equipment control system. According to the co-frequency encryption digitalized communication transmission control system, an existing unmanned plane space communication system is improved, and extremely outstanding significances for reducing the number of space communication frequency points of the unmanned plane, the weight of airborne end equipment, the emission power consumption of the airborne end and the airborne end antenna mounting space are achieved. The co-frequency encryption digitalized communication transmission control system has the benefits that the whole system adopts co-frequency transmission, so that planning and adjustment of the flying frequency applied to the special industry are greatly facilitated.
Description
technical field [0001] The present invention relates to a UAV signal transmission and control technology, in particular, it relates to a two-way encrypted digital air-to-ground wireless transmission of data signals, control signals, and video signals of multiple airborne devices on a UAV through the same frequency point system. Background technique [0002] The existing air-to-ground wireless transmission signals of UAVs mainly include: image transmission signals, flight control signals, and data transmission signals. Among them, the flight control system generally uses 2.4G, the image transmission system generally uses 5.8G, and the digital transmission system generally uses 433MHz / 868Mhz / 915MHz and other frequency bands. There are common public open frequency points with serious interference, illegal use of controlled / dedicated frequency bands, and illegal use of high power. Equipment, poor analog signal transmission quality, unencrypted data transmission, etc. [0003] ...
