高铁车站环境与设备监控系统计量设备量值可靠性研究

Research on Reliability of the Quantity Value of Measuring Equipment for Building Automation System in Highspeed Railway Station

高铁车站环境与设备监控系统(BAS)采用多种传感器和能源计量器具等计量设备。目前针对这些计量设备的量值溯源研究非常少。为此,对中国铁路北京局集团有限公司管辖范围内39座高铁车站BAS使用的计量设备开展调研,分析计量设备测量原理,提出计量设备量值保证方案,以保障计量设备测得的量值可靠。

A variety of sensors and energy metering devices are used in the building automation system(BAS)of high-speed railway stations.At present,there are very few researches on the traceability of the value of quantity of the measurement equipment applied in BAS.Therefore,based on the investigation of the measurement equipment applied in BAS on 39 high-speed railway stations under the jurisdiction of China Railway Beijing Group Co.,Ltd.,the paper analyzes principle of the measurement equipment.The guarantee scheme for value of quantity of measurement equip⁃ment is put forward to ensure the accuracy of the measured value of measurement equipment in BAS.
