硅微条探测器热控制系统(Tracker thermo control system,TTCS)是阿尔法磁谱仪(Alpha magnetic spectrometer,AMS)内一个重要的子系统,其主要任务是将AMS-02内部硅微条探测器产生的热量传导到辐射板以排散到太空,并维持探测器内部温度高度稳定.为提高可靠性,TTCS运行过程监控采取了结合自保护机制的分层监控实现策略.首先介绍了TTCS系统总体架构及组成;在此基础上着重描述了TTCS监控硬件平台,并分析了分层监控策略的模型结构和功能分配,硬件实现的自保护机制(Health-guard)进一步提高了系统运行安全度,最后结合地面模拟测试平台,给出了系统运行测试结果.该监控策略已成功应用在TTCS原型件设计中.
