Abstract

The Jiangmen Underground Neutrino Observatory (JUNO) is the second phase of the reactor neutrino experiment. The detector of the experiment was designed as a 20k ton LS with a Inner diameter of 34.5 meters casting material acrylic ball shape. Due to the gigantic shape of the detector there are approximate 10k monitoring point of temperature and humidity. There are about 20k channels of high voltage of array PMT, electric crates as well as the power monitoring points. Since most of the first phase software of the DCS was developed on the framework based on windows, which is limited by operation system upgrade and commercial software, the framework migration and upgrade are necessary for DCS of JUNO. The paper will introduce the upgrade framework of the DCS based on EPICS (Experimental Physics and Industrial Control System) running Linux OS. The implementation of the IOCs of the high-voltage crate and modules, stream device drivers, and the embedded temperature firmware will be presented. The software realization and the remote control method will be presented as well as the development of the GUIs by CSS (Control System Studio). The upgrade framework can be widely used in the project with the similar hardware and software interfaces.

朱诺探测器控制系统的框架升级

江门地下中微子观测站(JUNO)是反应堆中微子实验的第二阶段。实验的探测器设计为20k吨LS，内径34.5米，铸造材料为丙烯酸球状。由于探测器外形巨大，有大约10k的温度和湿度监测点。阵列PMT、电箱、电力监测点等高压通道约2万余条。由于DCS的第一阶段软件大部分是在基于windows的框架上开发的，受到操作系统升级和商用软件的限制，因此JUNO的DCS需要进行框架的迁移和升级。本文将介绍基于EPICS(实验物理与工业控制系统)在Linux操作系统下的DCS升级框架。介绍了高压板条箱和模块、流设备驱动程序和嵌入式温度固件的IOCs的实现。介绍了该系统的软件实现和远程控制方法，并利用CSS (control System Studio)开发了图形用户界面。该升级框架可广泛应用于软硬件接口相似的项目中。
