基于PC104的便携式ARINC429总线数据仿真与采集仪设计

摘要

针对特定机载设备总线通信状态的监测需求,设计了一种便携式ARINC429总线数据仿真与采集装置.为了减小体积与重量,达到设计目标要求,该系统以PC104单板机结合ZHHK429-PC104-Plus板卡为核心实现.论文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,可有效满足具有该总线接口的通用机载设备的状态监测及维护的需要.%According to the monitoring requirements of the airborne equipments bus state,we designed a portable ARINC429 bus data simulation and acquisition equipment. In order to reduce the volume and weight,the PC104 and ZHHK429-PC104-Plus card is used as the core of the system. The hardware structure and theory is described,the software structure and initialization of the card,receiving and sending of the bus data is analyzed. After testing,the system has good real-time,high reliability,can meet the requirements of the airborne equipments bus interface testing and needs.
