Manhole Water Level Monitoring System

System Overview

The underground drainage pipe network is like the "blood vessels" of a city, and manholes, as key nodes of the pipe network, their water level changes are directly related to urban waterlogging prevention and control, road traffic safety, and the protection of underground facilities. For this reason, Pingsheng has developed a manhole water level monitoring system. Through a full-link solution of "on-site accurate perception + platform intelligent analysis", it realizes real-time, automatic, and intelligent monitoring of manhole water levels, effectively identifies silted pipe sections, provides a scientific decision-making basis for urban drainage management, and meets emergency needs under extreme weather conditions such as sudden heavy rains.

System Composition

System Advantages

Precise perception, insight into every detail The measuring station is equipped with high-precision dual-channel water level sensors. The radar water level gauge and pressure water level gauge measure the manhole water level in a complementary manner, avoiding measurement blind areas, and keeping track of changes at the millimeter level.

Intelligent reporting, balancing battery life

• Automatically increases reporting frequency during the flood season to keep abreast of on-site conditions in a timely manner • Reduces reporting frequency during non-flood seasons to save energy • The entire station has a battery life of 2-5 years (depending on the reporting frequency)Intelligent Early Warning, Seizing the Initiative• Automatically triggers an alarm when there are abnormal fluctuations in liquid level data • Customizable multi-level alarm thresholds (such as warning water level, dangerous water level) to adapt to multi-scenario needs • When an alarm is triggered, the system instantly delivers the alarm to the responsible person through various means such as APP and platform pop-ups, specifying the manhole location, current water level, alarm level and suggested disposal measures • Early warning history can be queried, facilitating traceability and analysis of the causes of early warningsAuxiliary Decision-Making, Precise SchedulingQuickly locate blocked pipe sections or drainage bottlenecks, provide operation guidance for maintenance teams, and put an end to blind excavationMulti-Dimensional Management, Reducing Costs and Increasing Efficiency• Automatically generates water level historical curves and alarm records for each manhole, forming a complete electronic operation and maintenance file, so that management is based on evidence • Significantly reduces the frequency of manual inspections and lowers operation and maintenance costs • Through preventive maintenance, avoid huge repair costs caused by pipeline bursts, road collapses, etc.Non-Contact Installation, Ready to Use with One Hang• Battery self-powered, no need to break roads or erect poles • The water level gauge bracket is foldable, facilitating pipe network maintenance and inspection

Regulatory software

- Real-time monitoring visualization: GIS maps intuitively display information such as the distribution locations, real-time water levels, and equipment operating status of all monitored manholes, converging the scattered manhole data into a clear "urban drainage lifeline map". When the water level exceeds the preset threshold, the manhole icon automatically changes color.- Full-cycle data management: Automatically store all historical data, supporting multi-condition queries by time, region, manhole number, etc. Automatically generate daily, weekly, monthly, and annual water level change reports and trend charts, intuitively presenting the rules of manhole water level changes under different seasons, weather conditions, and time periods. It can analyze the drainage capacity of the pipe network, accurately identify "problematic manholes" that are prone to blockage and waterlogging, and carry out preventive maintenance such as pipeline dredging and pipe network transformation in advance.

- Intelligent equipment management: Remotely check on-site equipment information such as power supply status, network signal strength, and battery level in real-time, facilitating managers to promptly troubleshoot and repair.

- Drainage dispatch linkage: It can be linked with facilities such as pump stations and gates, intelligently starting and stopping drainage equipment based on real-time water levels to optimize the operation of the entire drainage system.
