基于LabVIEW的BESⅢ漂移室宇宙线实验慢控制系统

The LabVIEW based slow control system for the BESⅢ drift chamber cosmic rays test

BESⅢ漂移室宇宙线实验中需要对漂移室的气体比份、高压、电子学电压电流、风扇转速、温湿度等多种参量进行精确复杂的控制或长期监测,从而实现对探测器的建造质量进行全面测试,并将其各项指标调整到最佳状态。这要求我们在没有现成软件可用的情况下短期内从无到有开发出一套功能复杂灵活、点数庞大、稳定可靠、界面友好完善的大型探测器慢控制系统供物理学家们对探测器进行各种复杂的参数控制与监测。本文介绍了基于LabVIEW开发的BESⅢ漂移室宇宙线实验慢控制系统的设计方案及其具体实现方法。

In the Beijing Spectrometer （BESⅢ） drift chamber cosmic rays test, there are hundreds of parameters need to be adjusted or set, which involves several hardware devices. The main task of slow control system is to monitor and control tese parameters accurately, such as the gas rate, high voltage, voltage and current of electronics, fan speed, temperature and humidity and so on. The goal of the system is to test the construction quality of the detector and acquire a set of best parameters for it. Based on no ready-made software, we must develop a Slow Control System with the features of high flexibility and ease of use in limited time. This paper gives an introduction to the design and implementation of the LabVIEW based slow control system for the BESⅢ drift chamber cosmic rays test.
