摘　　要：设计了用于ADS注入器Ⅱ超导腔的低温恒温器控制系统。采用了基于EPICS的分布式控制系统架构,以PLC和串口服务器等为核心控制硬件,用PID算法实现了恒温器内氦压和液氦量的自动控制,压力控制精度约为±100 Pa,液氦高度误差约±10 mm。利用EPICS和Lab VIEW在局域网发布过程数据,实现了操作员界面对低温恒温器分布式系统的统一管理,控制系统设计性能满足使用需求,已经在ADS注入器Ⅱ超导高频腔水平测试中发挥了重要作用。Cryogenic module provides important low temperature environment for half wave resonance superconducting cavity in C-ADS injector Ⅱ, to ensure the effective operation of cryogenic module, a remote control system which is based on the physical and experimental industrial control systems（EPICS） is introduced in this paper. PLC and serial port server are used as field controllers. Host computer runs EPICS and Lab VIEW which are capable of getting and releasing data in local area net. Operators manage all the equipments through a CSS interface which is linked to local area net. The control system which is simple structure and reliable work, has played an important role in the level test of HWR superconducting cavity.
