摘要
飞机防滑刹车系统作为机载设备的重要组成部分,在飞机起飞与着陆过程中,起着至关重要的作用。采用TMS320F240芯片设计了一套状态监测的系统,对防滑刹车控制器的状态进行实时监测并将状态信息通过RS422通信发送至机载计算机。在介绍监测系统的组成结构的基础上,设计了故障诊断及开关量采集电路、RS422通信电路等硬件组成部分,给出了监测系统软件流程。实验验证,所设计的监测系统能满足要求。
Aircraft antiskid braking system as an important part of the airborne equipment plays a vital role in the process of aircraft take-off and landing.Paper uses TMS320F240 chip design a state monitoring system.The system monitors the status of the anti-skid brake controller and sends the information to airborne computer through RS422.Paper introduces the structure of the monitoring system and designs fault diagnostic circuit,switch acquisition circuit,and RS422 communications circuit.Paper explains the monitoring system software processes.Verified by experiment,the monitoring system can meet the requirements.
