Online Monitoring System Solution for Drainage Networks

The Online Monitoring System for Drainage Networks installs monitoring devices within drainage pipes, channels, and ancillary structures (manholes) to monitor parameters such as liquid level, flow velocity, flow rate, and on-site conditions in real-time. It features automatic alarm triggering for data exceeding limits and utilizes 4G/5G/NB-IoT wireless networks to transmit field data to the central monitoring software. This system provides strong guarantees for the safe and healthy operation of drainage networks, offers effective data support for network operation scheduling, maintenance management, and renovation design, and enhances the informatization management level of drainage networks. The system is expandable to include water quality monitoring, manhole cover displacement monitoring, hazardous gas concentration monitoring, and pressure monitoring.

Challenges

The high humidity, high corrosion, and sediment/debris-laden environment inside pipelines can easily cause sensor probe clogging and electrode passivation, affecting the accuracy of water level, flow, and water quality monitoring.
The confined space and poor ventilation in manholes make heat dissipation difficult for equipment, leading to potential failures during long-term operation.
Underground environments shield wireless signals; 4G/5G signals struggle to penetrate, while LoRa/NB-IoT transmission distances are limited, leading to data packet loss and delays. Gateway deployment locations are restricted, making signal relaying challenging.
Underground nodes lack stable mains power supply. When relying on battery power, endurance is limited by battery capacity.

Solution Details

Solution Background for Drainage Network Monitoring

As a critical infrastructure for urban construction, environmental protection, and flood control and drainage, the urban drainage system plays a vital role in ensuring social stability and the well-being of residents. With the accelerated pace of urbanization, urban drainage network systems have become increasingly complex, undoubtedly imposing stricter requirements on the maintenance and management of drainage networks. Therefore, strengthening the monitoring of drainage networks is particularly important. Especially in urban stormwater management, drainage network monitoring technology is a key link in ensuring urban water security, alleviating urban flood control pressure, mitigating water resource shortages, and improving water environment quality.

Approach

How we implement intelligence into your infrastructure step by step.

Requirement Survey & Network Census

Investigate network topology, pipe diameter, material, and operating conditions to clarify monitoring priorities. Liaise with water, environmental protection, and flood control departments to determine monitoring elements, accuracy, and warning requirements. Collect basic network data and correct deviations in outdated pipeline drawings.

Solution Design & Point Planning

Design the 'Perception - Transmission - Platform - Application' architecture, selecting IP68-rated anti-corrosion equipment. Plan monitoring points according to the principle of 'denser coverage at overflow risk points, full coverage of key pipe sections,' avoiding pipe bends and diameter change points. Determine the LoRa + gateway communication and battery/mains power supply方案 (scheme).

Infrastructure Construction & Device Deployment

Modify pipelines to install mounting bases, ensuring waterproofing and anti-corrosion treatment for井下点位 (manhole points). Install level, flow, water quality sensors, and manhole cover monitoring terminals,调试防堵塞功能 (debugging anti-clogging functions). Deploy above-ground gateways, establish communication links, and test the stability of underground-to-ground data transmission.

Platform Setup & Function Configuration

Deploy cloud-based and/or local monitoring platforms, building a GIS-based network visualization system. Configure异常预警阈值 (abnormal warning thresholds) for overflow and blockage. Develop data analysis modules and interface with city flood control and wastewater treatment plant scheduling platforms to establish data sharing interfaces.

Trial Operation & Optimization

Conduct a 1-3 month trial run covering different weather conditions (dry/rainy) to optimize warning thresholds and model parameters. Troubleshoot device failures and data deviations, and rectify issues遗留 (left over) from construction.
