用于CMS的前端电子配置系统

Front-End electronics configuration system for CMS

P. Gras, F. Drouhin, W. Funk, L. Gross, D. Vintache

摘要:

CERN的四个LHC实验已经决定使用商业SCADA(监督控制和数据采集)产品来监督其DCS(探测器控制系统)。因此,CMS DCS所使用的SCADA是来自ETM公司的PVSS II。该SCADA具有自己的数据库,适用于存储电压,温度和压力等常规控制数据。此外,需要存储校准数据和FE(前端)电子配置。这些数据量太大,无法存储在SCADA数据库中[1]。因此,将使用外部数据库管理此类数据。然而,该数据库应完全集成到SCADA框架中,应可从SCADA访问,并应受益于SCADA功能,例如报警、日志记录。对于原型设计,Oracle 8i被选为外部数据库管理器。校准常数和FE电子配置的控制系统的开发是与CMS跟踪器组和JCOP(联合控制项目)密切合作完成的(1)。(1)四个LHC实验和CERN IT/CO小组已将它们的努力合并起来建立实验控制系统,并为此于1997年12月底建立了JCOP。

英文摘要:

The four LHC experiments at CERN have decided to use a commercial SCADA (Supervisory Control And Data Acquisition) product for the supervision of their DCS (Detector Control System). The selected SCADA, which is therefore used for the CMS DCS, is PVSS II from the company ETM. This SCADA has its own database, which is suitable for storing conventional controls data such as voltages, temperatures and pressures. In addition, calibration data and FE (Front-End) electronics configuration need to be stored. The amount of these data is too large to be stored in the SCADA database [1]. Therefore an external database will be used for managing such data. However, this database should be completely integrated into the SCADA framework, it should be accessible from the SCADA and the SCADA features, e.g. alarming, logging should be benefited from. For prototyping, Oracle 8i was selected as the external database manager. The development of the control system for calibration constants and FE electronics configuration has been done in close collaboration with the CMS tracker group and JCOP (Joint COntrols Project)(1). (1)The four LHC experiments and the CERN IT/CO group has merged their efforts to build the experiments controls systems and set up the JCOP at the end of December, 1997 for this purpose.
