Embodiment 1

[0057] Example 1: See Figure 1-5 , the present invention provides a technical solution: a target-use unmanned aerial vehicle time division multiple access one station multi-machine measurement and control communication method, comprising the following steps:

[0058] 1) Start the ground control station and the drone group;

[0059] 2) The ground control station receives the second pulse signal of the satellite navigation system through the digital transmission station, and at the same time sends out a "clock synchronization command" in broadcast mode, and starts the measurement and control timer in the ground control station;

[0060] 3) After each UAV receives the second pulse signal of the satellite navigation system through the digital transmission station and receives the "clock synchronization command", it starts the measurement and control timer in each UAV to complete multi-machine clock synchronization;

[0061] 4) The ground control station communicates with each UA...

Abstract

The invention discloses a target type unmanned aerial vehicle time division multiple access one-machine multi-machine measurement and control communication method. The method comprises the following steps: (1) starting a ground control station and an unmanned aerial vehicle group; (2) sending out a clock synchronization command in a broadcasting mode while receiving a second pulse signal of a satellite navigation system through a data transfer radio by the ground control station, and starting a measurement and control timer inside the ground control station; (3) after receiving the second pulse signal of the satellite navigation system and the clock synchronization command through the data transfer radio by each unmanned aerial vehicle, and starting the measurement and control timer insideeach unmanned aerial vehicle to complete multi-machine clock synchronization; (4) communicating with each unmanned aerial vehicle by the ground control station in sequence to complete multiple roundsof communication periods; (5) after the multiple rounds of communication are ended, carrying out zero clearing on the ground control station and the measurement and control timer of each unmanned aerial vehicle and restarting; and (6) repeating the steps (2) to (5) until the communication is ended. According to the method, multi-machine clock synchronization is constructed by taking the second pulse signal of the satellite navigation system as reference, and the method is a one-station multi-machine measurement control communication method with low cost, generalization and operation stability.
