【摘要】 通过分级计量的方式，设置远传水表和压力传感器，对某典型办公建筑供水管网实时流量和压力进行长期监测，并对海量监测数据进行了筛分与解析。通过流量监测数据分析，探讨了系统设计秒流量及对应技术参数选择的合理性，阐述了建筑用水量在不同时段的分布规律，并论述了一、二级用水计量存在偏差的原因和不平衡率分析的适用条件。通过压力监测数据，对比分析了管网压力和对应流量的变化及分布规律，进而指出了压力变化与系统运行稳定之间的相关性。更多还原

【Abstract】 In this project, remote water meters and pressure sensors were set up in a typical office building, in the way of hierarchical measurement to carry out long-term monitoring the real-time flow and pressure. And then the massive monitoring data are screened and analyzed. Based on the analysis of flow monitoring data, this paper discusses the rationality of the design peak flow of the system, and the selection of corresponding technical parameters, describes the distribution of water consumption in different periods of time;, and discusses the reasons for the deviation of primary and secondary water measurement, also the applicable conditions of the imbalance rate analysis. Through the pressure monitoring data, the change and distribution law of pipe network pressure and corresponding flow are compared and analyzed, and then the correlation between the pressure change and the stability of the system is pointed out.更多还原
