摘　　要：中性束注入(Neutral Beam Injection,NBI)是全超导托卡马克核聚变实验装置(Experimental Advanced Superconducting Tokamak,EAST)辅助加热的重要手段.为避免装置在运行过程中出现事故,采用STM32作为主控芯片,设计了EAST中性束注入联锁保护系统,该系统的主要作用是在束引出过程中,实时监控各子系统的状态,避免打火等故障对系统造成损坏.为实现长距离传输信号和电位隔离,联锁保护系统采用光纤传输信号的方式.当联锁系统检测到光纤故障信号时可快速关掉电源系统输出,同时锁存故障信号,进行中性束注入器的联锁保护.通过现场实际测试,联锁保护响应时间在微秒级别,可达到安全设计要求.Neutral beam injection(NBI) is an important means of auxiliary heating for the Experimental Advanced Superconducting nuclear fusion(EAST).To avoid accidents during the operation of the device,the EAST neutral beam injection interlocking protection system is designed using STM32 as the main control chip.The main function of this system is to monitor the status of each subsystem in real-time during the beam extraction process,to avoid damage to the system caused by faults such as ignition.To achieve long-distance signal transmission and potential isolation,the interlocking protection system adopts the method of fiber optic signal transmission.When the interlocking system detects a fiber optic fault signal,it can quickly turn off the output of the power system,latch the fault signal,and interlock protection of the neutral beam injector.Through on-site actual testing,the response time of interlocking protection is within the microsecond level,which can meet the safety design requirements.
