在欧洲核子研究中心的ALICE实验中，探测器控制系统（DCS）采用多个相互作用的软件组件来完成其确保实验正确运行和监控的任务。本文介绍了前端电子通信（FeeCommunication）软件及其在DCS中的作用。FeeCommunication软件的中心任务是在上层DCS过程控制和ALICE内几个检测器的现场设备之间传递配置和监控数据。最低级别的FeeCommunication软件在DCS板上运行，DCS板是与现场设备直接接触并物理位于检测器内的专用嵌入式系统。中层和上层在位于计算室或其他外部位置的标准PC硬件上运行。本文重点介绍FeeCommunication软件的设计和实现，以及为满足所施加的可靠性和性能要求而采取的步骤，特别是与暴露于辐射和磁场的环境中的安全操作相关的步骤。
In the ALICE experiment at CERN, the Detector Control System (DCS) employs several interacting software components to accomplish its task of ensuring the correct operation and monitoring of the experiment. This paper describes the Front-End-Electronics Communication (FeeCommunication) software and its role within the DCS. The FeeCommunication software's central task is passing configuration and monitoring data between the top level DCS process control and the field devices of several detectors within ALICE. The lowest level of the FeeCommunication software runs on the DCS boards, specialized embedded systems which are in direct contact with the field devices and are physically located within the detector. The middle and upper layers run on standard PC hardware located in the counting room or other external locations. This paper focuses on the design and implementation of the FeeCommunication software and the steps that were taken to fulfill the imposed reliability and performance requirements, specifically those related to safe operation in environments exposed to radiation and magnetic fields.
