Shanghai's 'Smart Eyes' for Drainage Monitoring Make the City's 'Invisible Lifelines' Safer

STUMAN Intelligent Terminal: A Highly Integrated Design for Underground Drainage Monitoring

STUMAN's intelligent terminal features a pioneering highly integrated design, combining millimeter-wave radar, a camera, a remote data transmission RTU, and a battery compartment with a two-year operational lifespan into a single unit—eliminating the traditional equipment drawbacks of 'multi-component assembly and frequent failures.' Its IP68 waterproof and explosion-proof rating is perfectly suited to harsh underground environments. Installation requires no personnel to enter manholes; instead, the device mounts directly onto the well wall—significantly reducing construction risks and time costs.

Millimeter-Precision Water-Level Radar and Flow Velocity Monitoring

Equipped with a millimeter-precision water-level radar, the device measures liquid levels across a range of 0.1–40 meters with an accuracy error of only ±2 mm. Even in complex scenarios such as covered channels or deep wells, it precisely captures water-level fluctuations. Combined with Doppler-based flow velocity monitoring technology, it simultaneously calculates flow rates—providing critical data support for flood-control scheduling and turning the city’s once-common 'sea-viewing' flooding phenomenon into history.

Real-Time Video Streaming and Multi-Tiered Early-Warning Mechanism

The device integrates a 5-megapixel high-definition camera supporting real-time video streaming and snapshot capture. Managers can instantly view, via the platform, sediment buildup, equipment status, and even unauthorized wastewater discharge within manholes. Its proprietary 'laser positioning + automatic frequency compensation' technology ensures crisp, comprehensive imagery without blind spots. Upon detecting abnormal water levels or sudden flow velocity changes, the terminal immediately triggers a multi-tiered early-warning mechanism: pop-up alerts on the platform, SMS notifications, and mobile app push alerts respond simultaneously—and the system automatically uploads relevant on-site video clips.

Scalable Smart City Monitoring with Remote FOTA Upgrades

As a national high-tech enterprise, STUMAN has deep expertise in IoT technologies, and its products have been successfully deployed across multiple sectors—including water resources management and environmental protection. The terminal supports remote FOTA (Firmware Over-The-Air) upgrades and offers expansion interfaces for multiple devices, enabling seamless future integration with external sensors—such as water quality sensors—to deliver a scalable, 'growable' monitoring solution for smart cities.
