Research and Implementation of a New Type of RS-422 Bus Data Processing Algorithm

In order to meet the requirements of real-time monitoring and post processing of the new RS-422 bus parameters in flight test data of a certain type aircraft, the algorithm design and implementation scheme for the new RS-422 bus parameters is proposed. By analyzing the communication protocol and data packet format of the new RS-422 bus parameters, the method of adjusting the frame structure and resetting the sampling rate is decided to realize the analysis and reduction algorithm of the parameters, and the corresponding real-time monitoring and post processing software were designed. The software has been successfully used in the flight test of the aircraft, which provides a strong guarantee for the flight safety monitoring and data processing analysis.
