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。
Plane anti-skid braking system as an important part of airborne equipment plays an important role in the process of take-off and landing. A set of condition monitoring system was designed by TMS320F240 chip to monitor the status of anti-skid brake controller in real time and send status information to on-board computer through RS422 communication. On the basis of introducing the composition of the monitoring system, the hardware components of fault diagnosis, switch acquisition circuit and RS422 communication circuit are designed. The software flow of the monitoring system is given. Experimental verification, the design of the monitoring system to meet the requirements.
