摘要
为促进城市排水设施管理和环境监测的智慧化、信息化,设计了一种基于NB-IoT(Narrow Band Internet of Things)的多传感器窨井数据远程采集系统。实现了对城市窨井内水质、水位和井盖状态信息的远程上报和集中管理。为了满足多路传感器的低功耗供电和高精度数据采集需求,系统以锂亚电池供电,并对传感器调理电路进行改进。同时,软件中使用改进的数据处理算法进一步提高了传感器的检测精度。实际应用结果表明,系统整体运行平稳,功耗低,精度高,能够满足城市排水设施在线管理的要求。
In order to promote the intelligence and informationization of urban drainage facilities management and environmental monitoring,a multi-channel sensor inspection well data remote acquisition system based on NB-IoT(Narrow Band Internet of Things)was designed.Remote reporting and centralized management of water quality,water level,and inspection well cover status information in urban inspection wells have been achieved.In order to meet the requirements of low-power supply and high-precision data acquisition of multi-channel sensors,the system is powered by lithium sub-battery,and the sensor conditioning circuits are improved.At the same time,improved data processing algorithms are used in the software to further improve the detection accuracy of the sensors.The actual application results show that the overall system runs smoothly,with low power consumption and high accuracy,and can meet the requirements of online management of urban drainage facilities.
