以AG600水陆两栖飞机的起落架系统综合试验平台为基础,针对多路传感器信息采集与传输、主备单元之间信息重构、逻辑解算和驱动控制的信息共享需求,组建了一种RS485主从式通信网络,实现了以帧为单位的数据解析算法,并在此基础上进行了以帧元为单位的算法优化设计和实现。试验验证表明,该算法具备较好的实时性,满足起落架控制系统的实时通信控制需求。

Algorithm Implemented of Realtime Communication for Landing Gear Control System Based on RS485

Based on the platform of AG600 amphibious landing gear system, a kind of RS485 master-slave network was set up to meet the information sharing needs of information acquisition and transmission of multiple sensors, information reconfiguration between master and slave units, logic solution and drive control. From the communication network, the data analysis algorithm based on the frame is realized, and on this basis, the algorithm optimization design and implementation based on the frame element are carried out. Experimental results show that the algorithm has good real-time performance and meets the real-time communication control requirements of the landing gear control system.
