## Project Background
In the old urban area of this city, there are 3-5 incidents of methane or hydrogen sulfide poisoning in well chambers occurring annually during the high water level period of the rainwater and sewage confluence main pipeline during the rainy season. The Municipal Administration Bureau has initiated a pilot project to construct an intelligent monitoring network.
## Implementation Plan
Within the pilot area covering 12km², 80 YQRQ-100 solar-powered well chamber monitoring nodes are deployed, covering all Class I risk well chambers. The data is transmitted back to the municipal emergency command center and visualized through GIS integration.
– Dual power supply of solar energy and lithium battery, with a battery life of 5 years
– NB-IoT low-power backhaul, significantly reducing the unit price of nodes
– System predictive prompt: Automatically increase the sampling frequency 24 hours before rain
## Implementation Effect
In the pilot year, there were 31 abnormal alarms in the well chambers during the rainy season, with a 100% early response rate and zero poisoning incidents. The project was approved by the Municipal Administration Bureau to be expanded to 800 high-risk well chambers across the city within three years.
