摘　　要：为了给紫外遥感光谱仪的研制提供测试环境,充分测试紫外遥感光谱仪的功能和性能,基于光谱仪的实际测试需求设计了紫外遥感光谱仪地检系统;紫外遥感光谱仪地检系统由一块通讯数传板卡、一台高性能计算机和两个地检软件组成,适用于光谱仪单机、整机、整星等多种研制状态;硬件方面,通讯数传板卡选用的FPGA芯片是spartan-6系列的XC6SLX25;软件方面,两个地检软件分别是异步422控制软件和同步422快视软件,均在QT平台,使用C语言,采用多线程的编程思想实现;异步422控制软件不仅可以控制光谱仪执行功能还可以实时监视光谱仪状态;同步422快视软件除提供基础的数据储存解析和显示功能外,还具有比特位移除判别遥感包、图像伪彩色、时变线、光谱曲线高斯拟合等数据处理功能;经过多次试验验证,紫外遥感光谱仪地检系统运行稳定功能齐全,提高了仪器装调、定标和测试效率。In order to fully test the function and performance of an ultraviolet remote sensing spectrometer,which provides test environment in the development of the ultraviolet remote sensing spectrometer,a ground detection system based on the actual requirement of the spectrometer is realized.The ground detection system consists of a communication data transmission board,a high-performance computer and two sets of software above ground test.This system is suitable for a variety of testing environments to meet various requirements such as single spectrometer,complete spectrometer and whole-spacecraft.In terms of hardware,the FPGA chip selected on the communication data transmission board is XC6SLX25 of spartan-6 series.In terms of software,the asynchronous 422 control software and synchronous 422 data quick view software are achieved by using C language in QT Creator platform.The asynchronous 422 control software can not only control the execution function of the spectrometer,but also monitor the state of the spectrometer in real time.Then the data quick view software not only has the basic data storage and display functions,but also has the data processing functions of discrimination remote sensing package,pseudo color,real line,Gaussian fitting and so on.The test results show that the ground detection system for the ultraviolet remote sensing spectrometer runs stably and has complete functions,which raises the efficiency of instrument installation,calibration and testing.
