基于NB-IoT的低功耗智能地下井监测系统

Low Power Intelligent Underground Well Monitoring System Based on NB-IoT

摘要: 针对目前我国城市地下井管理存在的问题，提出了一种基于NB-IoT的低功耗地下井监测系统。该系统由下位机和上位机两部分组成。下位机以STM32L151为主控，实现对井下水位高度的测量、天然气安全范围的判断与井盖移动的判断，并通过NB-IoT将处理所得信息按照设定的周期上报至云平台。上位机使用SpringBoot和Vue框架作为系统Web端的开发框架，数据库选用MySQL关系型数据库，实现了用户管理、地下井监控、历史数据查看、设备管理等功能。为了方便用户管理终端设备，设计了手机App端。经系统测试表明，该系统可以实现对地下井的监控和管理。研究结果证明了该监控系统未来应用在智慧城市建设中的可行性，为地下井内信息的监控与管理提供了方案。

Abstract: A low power underground well monitoring system based on NB-IoT is proposed to solve the existing problems of urban underground well management in China. The system consists of two parts: the lower computer and the upper computer. With STM32L151 as the main control, the lower computer realizes the measurement of downhole water level height, the judgment of natural gas safety range and the judgment of manhole cover movement, and reports the processed information to the cloud platform according to the set reporting period through NB-IoT. The upper computer clearly uses SpringBoot and Vue framework as the development framework of the Web end of the system. The MySQL relational database is selected as the database to complete user management, underground well monitoring, historical data viewing, equipment management and other functions. In order to facilitate users to manage terminal devices, a mobile App terminal is designed. The system test shows that the system can realize the monitoring and management of underground wells. The research results prove the feasibility of the monitoring system in the construction of smart cities in the future, and provide a scheme for the monitoring and management of underground well information.
