Realization of Detector Control System of Physics Experiment

To meet the experimental requirements, modern physics experiments need to monitor a large number of indicators and give timely control commands. Considering the characteristics of large-scale physical experiments, including long-distance, various equipment, and massive data, a distributed detector control system (DCS) was developed. It implements communication with nonstandard hardware, data acquisition, alarm management, and data archiving functions. A set of experimental physics and industrial control system (EPICS) input–output controllers (IOC) is used to communicate with the hardware. Because the electronics use IPbus as a communication protocol, driver support is developed. The DCS implementation includes user interfaces, an alarm system, a data archiving system, and web services, among other things. At present, this DCS has been used by the experiment of Jiangmen Underground Neutrino Observatory (JUNO) to monitor the system status in electronics tests. It provides the necessary reference for the technical route of large-scale monitoring.
