According to 2024 data from the Ministry of Housing and Urban-Rural Development, China has more than 200 million urban manhole covers. The traditional manual inspection approach suffers from delayed response, high missed-detection rates, and elevated operation and maintenance costs. The resulting damage and loss of manhole covers have caused over 2,000 traffic accidents and hundreds of billions of yuan in direct economic losses. To address these issues, this study designs an IoT manhole cover status monitoring system based on the RISC-V core CH32L103C8T6. The system adopts multi-sensor fusion technology to preprocess parameters such as manhole cover displacement and inclination, verifies data validity using GPS positioning status, enables high-speed data transmission via the ADP-L610 communication module, and realizes real-time tracking of manhole cover status through 3D visualization on the cloud platform. This system effectively resolves pain points in traditional operation and maintenance, achieves precise and real-time monitoring of manhole covers, and provides an efficient and feasible industrial-grade solution for the management of urban smart infrastructure, thereby reducing related safety accidents and economic losses.References
