Design of an Intelligent Manhole Cover System Based on BeiDou Navigation

With the advent of the digital economy era, an increasing number of public infrastructure projects are moving towards smart, digital, and technological solutions. The number of city manhole covers is continuously increasing, but problems such as loss, damage, and displacement of these manhole covers frequently occur. Traditional manual inspections are unable to comprehensively monitor manhole cover information and address anomalies in a timely manner, which hampers urban management and poses threats to pedestrian safety.This project combines Internet of Things (IoT) technology with traditional manhole covers to develop smart manhole covers that can be remotely monitored. The system comprises a mobile application and intelligent manhole covers, with the latter equipped with functions such as sewer water level detection, harmful gas detection, BeiDou positioning, and manhole cover tilt angle detection. The STM32F103 chip uploads the detection data to an OLED display and a wireless communication module, and then uses UWB communication technology to transmit it to a server. The server performs big data analysis, processing, integration, and storage. The management platform acquires real-time manhole cover information, monitors real-time data, issues alerts based on the data, and ensures the timely handling of manhole cover and sewer anomalies, reducing harm to pedestrian safety and enhancing urban management and governance.
