摘要： 为了实现对消火栓状态的实时监测，掌握其水压、流量、温度的数据信息，研制了消火栓监测仪，对数据传输信号强度与消火栓状态实时监测方法进行分析与研究。分析基于NBIoT网络传输的消火栓监测仪在多种空间情形下的信号强度。对市政消火栓进行实时监测，从动压与静压两方面分析其水压变化趋势。分析阀门状态、探测周期对流量监测的影响。结合当地气温验证供水管网内水源温度监测的准确性。实验结果表明：消火栓监测仪数据传输可靠，压力在0～400 kPa 范围内监测准确、流量在0.2～25 L/s 范围内测量灵敏、温度监测数据与当地气温相符，满足消火栓状态实时监测需求。

Abstract:

In order to monitor the real-time status of water pressure,flow and temperature of fire hydrants, a fire hydrant monitor is developed, and signal strength of data transmission and real-time monitoring methods of fire hydrant status are analyzed and studied. Firstly, analyze the signal strength of the hydrant monitor based on NB-IoT network transmission in various space situations. Secondly, the real- time monitoring of a municipal fire hydrant is carried out, and its water pressure change trend is analyzed from both dynamic pressure and static pressure. Then,the effects of valve status and detection cycle on flow monitoring are analyzed. Finally, combined with local temperature, the accuracy of temperature monitoring in the water supply pipe is verified. The results show that the data transmission of the fire hydrant monitor is reliable, the pressure is accurately monitored in the range of 0~400 kPa, the flow rate is sensitively measured in the range of 0.2~25 L/s, and the temperature monitoring data is consistent with local temperature. The results meet the needs of fire hydrant monitoring.
