Abstract

The invention provides a cooperative measurement system response-type bidirectional data communication method. The cooperative measurement system response-type bidirectional data communication method comprises the following steps that: a first machine transmits a frame of data to a second machine; the second machine performs FSK demodulation so as to obtain a frame sequence number of the first machine and corresponding data and judges whether the frame sequence number of the first machine and a frame sequence number of data which are to be transmitted to the first machine by the second machine accord with a defined rule, if the frame sequence number of the first machine and the frame sequence number of the data which are to be transmitted to the first machine by the second machine accord with the defined rule, the second machine receives the data and transmits one frame of data to the first machine, otherwise, the second machine discards the frame of data, and re-transmits a last frame of data; and the first machine performs FSK demodulation on the data transmitted by the second machine so as to obtain a frame sequence number of the second machine and corresponding data and judges the frame sequence number of the second machine and a frame sequence number of data which are to be transmitted to the second machine by the first machine accord with a defined rule, if the frame sequence number of the second machine and the frame sequence number of the data which are to be transmitted to the second machine by the first machine accord with the defined rule, the first machine receives the data and transmits a next frame of data, otherwise, the first machine re-transmits the frame of the data; and the above steps are repeated.

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...
