摘要
针对飞行器测试实验阶段需要对飞行器各种信号进行模拟,以配合测试系统的工作,设计了一种基于以太网传输接口、以FPGA为控制核心的外系统等效器。该等效器采用W5300实现以太网与上位机进行通信,命令下发至主控板FPGA进行解析转发,来控制协调各个功能板产生需要的信号,包括27路直流信号、17路状态信号、15路脉冲信号以及3路正弦交流、平台力矩电流、数字串口、马达电源等信号。与其他设备联试结果显示,该等效器可靠性高且功能稳定,已成功应用于某航天测试系统。
Aiming at the experimental stage vehicle test,the need for aircraft to match various signal simulation test system ,a system was designed based on Ethernet transmission interface,using FPGA as the control core of the external system equivalent device. The equivalent device adopts W5300 to realize the communication between PC and FPGA Ethernet ,sent to the main control board command parsing forwarding ,to control the function board coordination produce the required signal,including 27 DC signal,17 Road,15 road condition signal pulse signal and the 3 Road sinusoidal alternating current,torque current,serial,digital platform motor power signal. Test results in combination with other equipment display,high reliability and stable function of the equivalent device,has been successfully applied in a space test system.
