摘要
针对目前外系统等效测试设备研发周期长,无法提高效率等问题,设计了一种模块化、通用化的,能够进行批量化与标准化生产的测试设备。系统以FPGA作为主控核心,以太网和RS422总线分别作为上位机与背板和板间通信接口,再辅以各种具体的功能化的板卡,实现了任务所要求的信号的输出,经过测试,结果符合具体要求并且性能稳定。体现了模块化与通用化思想在设备研发中的重要作用。现已成功应用于某航天测试系统中。
In view of the long development cycle of external system of equivalent device,and the improvement of the efficiency of the device,a modular and universal equivalent device is designed. System uses FPGA as the control core,RS422 bus and Ethernet respectively as communication interface between PC and the backplane and board,supplemented by a variety of specific functions of the board to achieve the output signal. After testing the results accord with the specific requirements. It reflects the important role of modularization and universal thought in the research and development of equipment. Now it has been successfully used in the test space craft systems.
