Abstract: In the centralized flight control system for carrier aircraft, the differences of operating frequency among the external equipment, the serial communication equipment, the ARINC659 bus and the processing software lead to the mismatch of the rate between writing data to Bus Interface Modular (BIM) and reading data from Control and Program Modular (CPM), resulting in the missing of and the repeated analysis of the data packet. The reliable data transmission can not be guaranteed. By analyzing the reasons of conflicts in reading and writing in details, corresponding solutions are given to problems of incomplete data packet reception and repeated analysis, a new data packet format is designed and a data transmission scheme is proposed. The experiments prove that the scheme can guarantee the data-integrity and avoid repeated analysis of the data packets, improving the reliability and efficiency of the software.
