摘　　要：针对传统的卫星电源控制器(PCU)测试系统出现的定制化严重、运行维护困难、成本投入大等问题,该文设计并实现了一种基于ARM+FPGA架构的通用测试系统。该架构通过利用FPGA自身高速和并行处理数据的能力,实现了PCU常用的1553B、CAN和RS422多种总线通信接口整合。利用ARM芯片强大的算法处理和逻辑运算能力,移植并运行了UCOSII嵌入式操作系统,采用以太网芯片将多种通信接口转换成以太网接口,实现与通用测试上位机的数据传输。实际型号应用表明,该测试系统能够稳定适配不同的PCU,成本较低,维护较方便,具有一定的推广价值。Aiming at the problems of serious customization,difficult operation and maintenance,and large cost investment in the traditional satellite power conditioning unit(PCU)test system,a general test system based on ARM+FPGA architecture was designed and implemented.This architecture realizes the integration of various bus communication interfaces such as 1553B,CAN and RS422 commonly used by PCU by using the FPGA’s own high-speed and parallel data processing capabilities.UCOSII embedded operating system is transplanted and run by using the powerful algorithm processing and logic operation capabilities of ARM chip,and the Ethernet chip is used to convert various communication interfaces into Ethernet interfaces to realize data transmission with the general test host computer.The actual model application shows that the test system can stably adapt to different PCUs,with low cost,convenient maintenance,and a certain promotion value.
