摘要

锗酸铋(Bismuth Germanate

BGO)量能器是我国即将发射的暗物质粒子探测卫星的关键分系统之一。在为期数年的工程研制过程中，需开展大量测试工作，包括初样鉴定件、正样飞行件共计40块前端电子学板的性能测试，初、正样共计约1600个光电倍增管的LED光源刻度测试，以及初、正样单机各长达数月的多项地面环境模拟试验。针对以上测试和试验过程中的自动化数据采集和指令参数配置等需求，设计开发完成了一个基于LabWindows/CVI开发平台和虚拟仪器技术的自动化测试系统，并投入实际应用，减轻了实验人员的工作强度，提高了测试效率，为暗物质粒子探测卫星BGO量能器的研制和工程生产的顺利进行提供了保障。

Abstract

Background: Bismuth Germanate (BGO) calorimeter is the key sub-detector of the Dark Matter Particle Explorer (DAMPE) satellite. There are extensive tests including the performance testing of 40 Front-end Electronics (FEE) in the engineering development model and flight model

the LED source calibration of 1600 Photomultiplier Tubes (PMT) and different kinds of ground environment simulation test as long as several months during production. Purpose: This study aims to ensure the progress of production by developing a ground test system to meet the demand for automated data collection and command parameters during the experiments and tests. Methods: First of all

the testing requirements were analyzed in details

then a framework of hardware and software was designed according to available resources. Finally the software was implemented and optimised by means of LabWindows/CVI and virtual instrument technology to fulfil all test functionalities. Results: The user interface (UI) and function modules of the software meet the requirements of data acquisition and automatic control for the BGO calorimeter of DAMPE satellite. Conclusion: This testing system has been put into practical application for more than 18 months

successfully reduced the working strength and improved the test efficiency. Abstract
