在北京正负电子对撞机（BEPCII）升级改造项目中，北京谱仪（BESIII）新型探测器控制系统（DCS）已经建成，并在BESIII调试中成功运行。 DCS的主要任务是监视和控制BESIII探测器的状态，保证探测器的安全运行。即使存在来自各种设备的大量分布式 I/O 通道，DCS 也必须为探测器操作员提供统一且一致的接口。为此，DCS采用层次化组织方式，分为三层：前端层（FEL）、局部控制层（LCL）和全局控制层（GCL）。在 FEL 中，使用的设备范围从简单的传感器到复杂的基于计算机的设备，如嵌入式系统和可编程逻辑控制器 (PLC)。已经为 LCL 开发了基于 LabVIEW 的软件框架。 GCL已使用网络通信和Web服务器技术。本文将详细介绍DCS的设计和实现。还将讨论其性能和可靠性。
In the upgrade project of the Beijing Electron-Positron Collider (BEPCII), a novel Detector-Control System (DCS) for the Beijing Spectrometer (BESIII) has been built and started its successful operation for the BESIII Commissioning. The main task of the DCS is to monitor and control the status of the BESIII detector and to guarantee a safe operation of the detector. The DCS must provide a uniform and coherent interface to detector operators even though there are a large number of distributed I/O channels from a large variety of equipments. For this reason, the DCS is hierarchically organized and divided into three layers: front-end layer (FEL), local control layer (LCL) and global control layer (GCL). In the FEL, devices ranging from simple sensors up to complex computer-based devices like embedded systems and programmable logical controllers (PLC) are utilized. A LabVIEW-based software framework has been developed for the LCL. Network communication and web server technologies have been used for the GCL. This paper will give a detailed introduction to the design and implementation of the DCS. Its performance and reliability will also be discussed.
