Design of temperature monitoring system for Space Environment Simulation and Research Infrastructure based on EPICS

Space Environment Simulation and Research Infrastructure (SESRI) is one of the important technologies to promote the development of aerospace industry, and the ion accelerator system is one of the more important subsystems in SESRI. Aiming at the problem that the temperature of the ion accelerator is too high and the stability of the electric field is affected by the long-term operation of the ion accelerator, this paper designs an ion accelerator temperature monitoring system based on EPICS. In this paper, the temperature control principle of the ion accelerator is firstly analyzed, and according to its characteristics, the robust control of the temperature of the ion accelerator is realized by using the PID control algorithm. Secondly, based on EPICS, the overall scheme of the control system is designed, the EPICS operating environment is built, the communication function between the IOC and the underlying equipment is designed, and the OPI human-computer interaction is realized. Finally, the control effect and operation of the system are simulated. The simulation results show that the system has good stability and can control the temperature of the ion accelerator to meet the project control requirements.
