Abstract

The cooperative measurement system response type two-way data communication method of the present invention comprises the following steps: the first machine sends a frame of data to the second machine; the second machine performs FSK demodulation to obtain the frame number and corresponding data of the first machine, and the second machine judges Whether the frame number and the frame number of the data that the second machine will send to the first machine conform to the defined rule, if so, the second machine receives the data, and sends a frame of data to the first machine, if not, discards this frame data, and resend the previous frame of data; the first machine performs FSK demodulation on the data sent by the second machine, and obtains the frame number and corresponding data of the second machine, and the first machine judges that the frame number is the same as the first machine will send to the second machine Whether the frame number of the data sent by the second machine conforms to the defined rule, if so, the first machine receives the data, and sends the next frame of data, if not, resends the frame of data; repeat the above steps.

Description

technical field [0001] The invention relates to a two-way communication technology between cooperative targets, in particular to a response-type two-way data communication method for a cooperative measurement system. Background technique [0002] At present, in the cooperative measurement system, there is often a need for communication between the cooperative targets, but if the cooperative measurement system is in space, it will be affected by many unreliable factors, and the communication system will become very unreliable. Frame loss and frame errors occur. Contents of the invention [0003] The purpose of the present invention is to provide a cooperative measurement system response two-way data communication method, which can effectively prevent frame loss and frame error during the communication process of the cooperative measurement system. [0004] In order to achieve the above-mentioned purpose, the present invention provides a response type two-way data communica...
