Portable Detection Equipment of an Airborne Equipment Based on ARINC429 Bus

摘要:

针对特定某种机载设备 ARINC429总线通信状态的监测需求,设计了一种便携式检测设备。为了减小体积与重量,达到设计目标要求,该系统以 PC/104嵌入式工业控制计算机结合 ZHHK429-PC104-Plus429通信板卡为核心实现。文章描述了系统硬件的组成及原理,分析了软件结构及板卡的初始化、总线数据接收及发送的方法。经测试,该系统实时性好,可靠性高,可有效满足特定机载设备的状态监测及维护的需要。

Abstract:

According to the monitoring requirements of the airborne equipments bus state, a portable detection equipmentwas designed . In order to reduce the volume and weight, the PC104 and ZHHK429-PC104-Plus card was used as thecore of the system. The hardware structure and theory was described, the software structure and initialization of the card,receiving and sending of the bus data was analyzed. After testing, the system had good real-time, high reliability, couldmeet the requirements of the airborne equipments bus interface testing and needs.
