基于PXI总线的装甲车辆武器测试系统的设计

Design of Test System of Armored Car Weapon Based on PXI bus

基于VXI、PXI总线进行各种自动测试系统的开发是目前国际国内较为流行的故障检测诊断方案,文章介绍了一种基于PXI总线的装甲车武器系统自动测试系统;简要说明了PXI系统总线,该系统以PXI內嵌主控计算机为核心,以PAWS的软件为开发环境,基于硬件系统的模块化设计,软件系统利用多线程技术对实时测试系统软件进行了设计和实现,并综合运用标准接口及总线技术、故障诊断技术等来实现系统的综合设计;经验证其有效地提高了系统的可靠性、灵活性,通过实际测试与评估,证明该系统设计方案切实有效。

The development of automatic test system hased on VXI or PXI bus is a famous world while solution which can he used to examine and diagnose nowadays. An automatic test system for weapon system of armored car based on PXI bus is presented in the paper. A PXI system bus is introduced briefly. The system designs and realizes the real--time test system software which uses PXI in--line computer as its core part and takes PAWS software as development environment based on hardware system, the software system makes use of multithreading technique , and uses standard interface and bus technology , error diagnose technology to realize the integrate design of system. The system reliability and flexibility are greatly enhanced. The design of system is practically valid after actual test and valuation.
