| 摘 要: 近几年随着城市供水管道的日益复杂化，城市供水系统的监测变得难以管理。为了更好地监测城市供水系统的运行状态，借助窄带物联网(Narrow Band Internet of Things, NB-IoT)的低功耗优势，设计了一个基于NBIoT的水务管网参数监测系统。该系统以低功耗STM32L4芯片为控制核心，实现了供水管网实时数据的采集与NB-IoT数据的传输，水务管网的参数会被上传至服务器并通过浏览器显示。本文重点设计了现场数据采集设备的硬件电路，开发了NB-IoT的网络传输。测试表明，该监测系统实现了水务管网的数据远传和远程控制，具有一定的研究和开发价值。 |

| Abstract: In recent years, increasing complexity of urban water supply pipeline makes it difficult to monitor and manage urban water supply system. In order to better monitor the operating status of the urban water supply system, this paper proposes to design a water pipeline network parameter monitoring system based on NB-IoT (Narrow Band Internet of Things) with low power consumption. The system uses the low-power STM32L4 (STMicroelectronics) chip as the control core to realize real-time data collection of the water supply pipeline network and NB-IoT data transmission. Parameters of the water pipeline network are uploaded to servers and displayed through browsers. This paper focuses on designing the hardware circuit of field data acquisition equipment and developing the network transmission of NB-IoT. Tests show that the proposed monitoring system realizes remote data transmission and remote control of the water pipe network, and has certain research and development value. |
