Urban Flooding Monitoring and Early Warning Solution

　　LED displays and audio‑visual alarm devices are installed at both tunnel entrances and near flood‑prone areas, while telemetry terminals and video cameras are deployed along low‑lying sections inside the tunnel. The telemetry terminals use electronic water level gauges to measure inundation depth and transmit data to the management platform at set intervals. When the water level reaches a predefined alert threshold, the telemetry station captures an image and sends it back to the control center; simultaneously, the LED display and high‑volume speaker activate an audio‑visual warning to alert passing vehicles to exercise caution. Once the water level falls below the safety threshold, the alarm is automatically deactivated. Through this system, the drainage authorities can gain a comprehensive understanding of urban flooding conditions and promptly implement flood‑prevention and drainage measures, enabling all‑round monitoring and centralized dispatch management of the city’s drainage network.

　　The system features intelligent power‑management capabilities that automatically adjust its operating mode based on the severity of water accumulation, ensuring continued operation even during prolonged periods of overcast and rainy weather.

　 　Product Advantages

　　 Advantage 1: One-stop solution for customer needs

　　Advantage 1: We offer a comprehensive portfolio, ranging from system platforms to monitoring instruments, and end-to-end services spanning product supply to system operations and maintenance. Our platform is deployed locally, addressing customers’ concerns about system security and potential supply-chain bottlenecks.

　　 Advantage 2: Low environmental requirements and simple construction.

　　 • It has low space requirements, needing only a 114 mm‑diameter pipe for installation. Moreover, once the project is implemented, changes in the surrounding environment will not affect the measurement results, and the equipment will have virtually no impact on traffic flow.

　　• Equipped with built-in solar charging, it requires no grid power and is safe and reliable;

　　• Supports 4G all‑network compatibility and NB‑IoT all‑network connectivity, with low network requirements.

　　• Integrated design, incorporating an RTU, a lightning protection module, and a solar charging module, eliminating the need for an external distribution box.

　　• On-site installation and commissioning via the mobile app, eliminating the need for a computer or other debugging equipment.

　　 Advantage 3: Zero drift, stable and reliable

　　• An electronic water level gauge is used as the liquid-level measurement sensor, offering zero-point drift-free operation and immunity to interference.

　　• Features a 304 stainless steel housing, reducing the risk of equipment failure due to cracking while enhancing the device’s protection rating;

　　• Use low-temperature-coefficient sealants, and by combining sealants with different coefficients, minimize circuit failures caused by sealant expansion and contraction.

　　• A sealant potting process refined over many years, featuring stable equipment and a low failure rate;

　　 Advantage 4: Equipment operating conditions are monitorable.

　　• Monitor equipment status in real time to reduce fault‑resolution time:

　　• Solar Voltage Monitoring

　　• Backup battery voltage monitoring

　　• Communication Signal Strength Monitoring

　　• Equipment temperature and humidity monitoring

　　• Equipment Peripheral Fault Monitoring

　　• Equipment Removal Alarm

　　• Equipment Tipping Alarm

　　 Advantage 5: Ultra-low power consumption, with minimal requirements for the power supply system.

　　• Utilizes ultra-low-power components; the sensor operates at a minimum of 6 V, and results can be read immediately upon power-up. Each measurement requires no more than 3 seconds of sensor activation.

　　• The solar charging control unit employs maximum power point tracking (MPPT) technology to maximize the output power of the solar panel, ensuring that even under low-light conditions, it can supply the power required for device operation.

　　• It uses a lithium battery as the backup power source, ensuring the device can operate normally for more than 20 days without external power.

　　• Low-power design eliminates the need for large-capacity backup batteries, enabling long‑term operation powered solely by solar energy and thereby reducing overall project costs.
