基于间接核查法的流量计云在线运行核查方法

Cloud online operation verification method of flowmeters based onindirect verification method

在供热物理设备网中,除不同规模的流量计群外,还设有大量与流量有关的设备及部件。本文研究了利用供热系统的机理、被核查流量计的相关参数、供热物理设备网中设置的具有流量特性的设备或部件来判断被核查流量计工作状态的方法,并在此基础上提出了流量计的云在线运行核查技术流程,以快速判断在线应用的流量计的技术性能是否满足使用要求,解决供热企业核查人员及核查仪器设备不足的缺陷,有效提升智慧供热系统数据质量和提高控制系统的安全。

In the heat supply physical equipment network,in addition to the different scale flowmeter groups,there are also a large number of flow-related equipment and components.This paper studies the method of determining the working status of the verified flowmeter using the mechanism of heat supply system,the relevant parameters of the verified flowmeter,and the equipment and components with flow characteristics set up in the heat supply physical equipment network.On the basis,the cloud online operation verification technology process of the flowmeters is proposed to judge whether the technical performance of the flowmeters applied online meets the usage requirements,solve the problem of heat supply enterprises with insufficient verification personnel and verification instruments and equipment,and effectively improve the data quality of smart heating system and improve the safety of the control system.
