Design of Detector Preamplifier assembly Test System

摘要:

利用虚拟仪器技术可以实现对探测器前放组合件测试系统等高精度测试系统的开发；系统以工控机为主控平台,结合自研的图像采集与处理单元、切换控制单元,利用虚拟仪器开发软件LabVIEW2011,实现对单个前放模块常温测试,对两发探测器前放组合件同时进行高低温、常温测试；对探测器盲元的检测做了详细的说明和分析；通过现场实际使用,证明了该系统测试精度高,完全满足了微弱小信号的测试,自动化程度高,测试速度快,实现了对测试数据、图表、图像的采集、保存和回放。

Abstract:

A detector preamplifier assembly test system is introduced by using virtual instrument technology. The system takes IPC as the hosting platform, jointly with image acquisition and processing unit, switching control unit and virtual instrument software Labview2011. Therefore temperature test of single preamplifier module as well as high-low temperature test and temperature test of two detector preamplifier assemblies simultaneously can be realized. Detection to blind detector element has been given a detailed description and analysis. Through actual application on site, we can demonstrate that the system has a high precision, which satisfy the weak small signal testing adequately. In addition, the system with a high degree of automation and fast test speed can implement capture and save test data, charts and images.
