Jiangshan City is located at the junction of Zhejiang, Fujian, and Jiangxi provinces, with mountains and hills accounting for 88.8% of its area. It has numerous reservoirs and ponds, and in recent years has been plagued by risks such as geological disasters, floods, aging bridges, and gas leaks. Traditional safety management suffers from pain points such as multiple risk types, insufficient regulatory coverage, and data silos between departments, necessitating the construction of a unified IoT platform and urban safety monitoring and early warning system.

Adopting a five-layer architecture and standard specifications of "sensing, transmission, knowledge, and application," the solution integrates sensing devices in seven major areas: water conservancy, geological disasters, bridges, flooding, sewage pipelines, fire safety, and piped gas. Through the deployment of IoT terminals such as Visual Deformation Instrument, Integrated GNSS Monitoring Station, tipping bucket rain gauges, submersible water level gauges, combustible gas detectors, and intelligent fire hydrant monitoring equipment, a unified IoT platform and urban safety digital monitoring and early warning platform are built. This achieves centralized management and data aggregation of IoT devices throughout the city, connecting the entire closed-loop process of "real-time monitoring - intelligent early warning - analysis and judgment - coordinated response."

The platform open to multiple departments including housing and construction, natural resources and planning, water conservancy, fire protection, and gas, and covers the city, town/street, and village/community levels, effectively avoiding redundant investment and reducing administrative costs. By ensuring the safety of key scenarios such as reservoirs, ponds, geological disaster sites, bridges and tunnels, and gas pipelines, it has improved the level of refined management of safety risks in county-level cities and enhanced people's sense of safety.
