摘要

为了对卫星载荷广角极光成像仪下传的大量遥感数据进行采集并实时解析成像，设计实现了广角极光成像仪图像采集与快显多功能监测系统。根据系统工程需求分析，利用数据采集卡接收来自RS-422接口的遥感数据，在VC++平台上开发上位机软件，应用多线程与定时器联合编程实现并行的数据采集、数据解析、图像处理及快速显示，并实现了光子计数率显示、像素点亮度值显示、图像亮度值调节、生成原始数据曲线、图像回放、图像局部放大等多种功能。通过系统与广角极光成像仪的联合测试，实验结果表明：该系统能够正确接收遥感数据，准确解析辅助参数及多模式下的图像数据并快速显示成像，多种功能执行正确且运行稳定。系统能实时、准确地反映仪器状态及性能，是广角极光成像仪研发各阶段不可或缺的一部分。

Abstract

In order to collect the mass data loaded from wide angle aurora imager and analyze remote data to display images in real time

the image acquisition and fast display versatile detection system for wide angle aurora imager are designed and implemented. According to system requirements

by utilizing data grabbing card to receive remote data from RS-422 interface

the software which is developed on computer with VC++ uses joint programming of multithread and timer to achieve data acquisition

data analysis and image fast display at the same time

as well as other functions

such as photon count rate display

brightness value display

brightness value adjustment

original data curves generation

image replay and image partial amplification. Through joint test of the system and wide angle aurora imager

the results indicate that this system could receive remote data correctly

analyze parameters exactly and multi-mode image data and quickly display images

all functions could execute correctly and run stably. The system could reflect instrument status correctly in real time

which is the integral part of each phase in development of wide angle aurora imager.
