摘　　要：为实现地面模拟在轨飞行环境试验中星载仪器遥测信号的实时采集与显示,设计了一种以单片机为数据处理器、FPGA为采集控制器的多处理器外部遥测模拟系统,实时采集和处理多路遥测信号,并通过串口传输至上位机,由上位机通过VC界面显示遥测信号曲线,达到实时监测仪器工作状态的目的;实验表明,遥测信号中电压信号与正常工作值的偏差在0.3V以内,温度信号波动范围小于0.1℃,系统运行稳定可靠,满足仪器外部遥测系统的任务要求;整个系统各模块功能明确,易于扩展成复杂系统,高效地实现更多的功能。In order to sample and display the remote measurement signals of satellite payload during the space environment experiment mocked on the land, an exterior remote measurement simulation system was designed based on MCU and FPGA. The system samples and re- solves the remote measurement signals and transmits the data to PC via serial port, and displays the curves of the signals by VC interface to monitor the working state of satellite payload. The experiment shows that the standard deviation between each voltage remote measurement signal and the normal value is 0.3V, and for the temperature signals the standard deviation is 0. 1℃. The data shows that the system runs stably and reliably and satisfies the demand of remote measurement for satellite payload. The whole system works effectively and is easy to extend the system to achieve more functions.
