HIRFL cooling water-monitoring system design and construct

Abstract

HIRFL is a heavy ion accelerator built by the Institute of Modern Physics, Chinese Academy of Sciences, which constitutes a total length of over 900 m by the SFC, SSC, CSRm, CSRe and so on. It bears a lot of research task of the country, so to ensure its safe operation is very important. Cool-water system is a key part in HIRFL, and the parameters of the cool-water system need to be monitored before an accident occurs. This article describes three aspects of the system, from the water leakage detection, pressure monitoring, to the water-level monitoring. A complete monitor system was designed and constructed, including the hardware structure; the data transfer mode, as well as specific control program. C++, FLASH and SCADA are used in the monitoring system. Fault alarm was performed timely and accurately by the monitoring system, and many accidents were avoided. Water system monitoring is an important part of the accelerator control system. It will also play a major role in the construction of large-scale scientific device named HIAF in the further.
