Airborne equipment data transmission method, device and system based on time-sharing transmission technology

Abstract

The invention discloses an airborne equipment data transmission method, device and system based on a time-sharing transmission technology. The system comprises the airborne equipment data transmissiondevice based on the time-sharing transmission technology, airborne equipment, communication equipment and monitoring center physical layer equipment; and real-time navigation and state information data of multiple flight equipment is transmitted to a monitoring system in a time-sharing mode, therefore, the problems of data desynchrony, congestion, conflicts and the like are avoided, and on-line collaborative monitoring on the multiple flight equipment is achieved. According to the airborne equipment data transmission method, device and system based on the time-sharing transmission technology,the data receiving conflict problem of the monitoring end is solved at the airborne end, the defect that the physical resource of the monitoring end is limited is avoided, the operation load of the monitoring end is reduced, and meanwhile the monitored flight equipment number and type are greatly increased; and the frequency of data transmission between the airborne end and the monitoring end canbe adjusted, the communication equipment (such as a radio station and a network) is selectable, and data information transmission time synchronization among the multiple flight equipment is guaranteed.

Description

technical field [0001] The invention relates to the technical field of airborne RTK receiver equipment in the surveying and mapping industry, in particular to an airborne equipment data transmission method, device and system based on time-sharing transmission technology. Background technique [0002] With the development of high-tech technologies such as computers, artificial intelligence, and automatic driving, the types of airliners and drones are increasing, and their performance is becoming more and more perfect.
