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。
Aiming at the monitoring requirement of the ARINC429 bus communication status of certain airborne equipment, a portable testing equipment is designed. In order to reduce the size and weight, meet the design goals, the system is based on PC / 104 embedded industrial control computer and ZHHK429-PC104-Plus429 communication card. The paper describes the composition and principle of the system hardware, analyzes the software structure and the initialization of the card, the method of receiving and transmitting the bus data. Tested, the system is good real-time, high reliability, can effectively meet the needs of a particular state monitoring and maintenance of airborne equipment.
