摘　　要：为确保HL-2M装置能安全、稳定地进行初始等离子体放电实验,参考国际热核聚变实验堆(ITER)的安全联锁设计,并结合HL-2M装置的实际现状,建立了一套基于可编程逻辑控制器(PLC)慢控制的中央安全联锁系统。搭建了一套千兆光纤星形网用来满足各系统之间的通讯。中央安全联锁系统根据故障风险等级和预先设定的故障处理机制,协调各子系统进行联锁保护动作。WINCC监控画面显示各子系统的运行状态和故障信息。采用EPICS CA协议和S7nodave驱动实现了软IOC读取PLC变量,并结合C#编程实现了对主机大厅门禁访问系统的控制,保障了人员和设备的安全。该套中央安全联锁系统已经投入使用,平均扫描周期1~3ms,满足HL-2M装置初始等离子体放电的安全联锁保护需求。A central safety interlock system based on PLC slow control is established to make sure the safety performance of the first plasma on HL-2M tokamak.The system is referred to the safety interlock design of ITER.A gigabit fiber star network is adopted to realize the communication between the systems.The central safety interlock system coordinates with its subsystems to carry out the protection actions according to the failure risk level and the preset failure handling mechanism.The WINCC monitor screen displays the operating status and fault information of each subsystem.The EPICS CA protocol and S7 nodave driver are used to realize the soft IOC reading PLC variables,and combined with C#programming to realize the control of the access system of the HL-2M hall.The central safety interlock system has been deployed,with an average scanning period of 1~3ms,which meets the safety interlock protection requirements in the first plasma discharge of HL-2M tokamak.
