The Vital Role of Smart Manhole Cover Monitoring Terminals in Sewer Systems

As cities accelerate their pace, public facility management is evolving from “passive discovery” to “proactive warning.” Among urban infrastructures, manhole cover hazards occur frequently yet are often overlooked. The FST100-2020D Smart Manhole Cover Monitoring Terminal is revolutionizing this field, upgrading manhole cover management from blind spots to full-time online supervision, providing unprecedented safety protection and intelligent operation for sewer systems.

Like an invisible guard, the sensor beneath the manhole cover silently detects tilt, unauthorized opening, or water accumulation. Once any abnormality is detected, the system instantly triggers an alarm and sends the alert via NB-IoT or 2.4 GHz networks to the cloud platform. Management personnel can immediately view the abnormal status through the backend system, mobile APP, SMS, or email. This greatly shortens response time and effectively prevents traffic accidents and public safety risks caused by manhole cover anomalies.

Moreover, the smart manhole terminal plays a crucial role in sewer water level monitoring. Its built-in ultrasonic level detection can sense rising water levels in real time. Once the preset threshold is exceeded, the system automatically sends an alert. Even smarter, the device can adjust its data collection frequency and alarm thresholds dynamically, enabling more proactive monitoring during rainy seasons or sudden storms.

In real projects, such smart manhole systems not only enhance safety but also significantly improve the operational efficiency of urban drainage networks. Traditional manual inspections are inefficient and prone to missing critical moments. Now, with smart manhole terminals, pipeline management becomes “always online.” Each manhole location and status is marked on the backend map, with abnormal covers highlighted. Combined with a work order dispatch system, this greatly reduces maintenance costs and response times.

In the field of smart water management, such systems also provide strong technical support for flood prevention. Sewer water level monitoring can accurately identify which drainage points may become risk spots, enabling early warnings and proactive interventions before heavy rain strikes. During post-storm water peak reduction, it also helps optimize drainage strategies and resource allocation, improving efficiency and reducing urban flooding losses.

The advantages of the smart manhole cover terminal lie not only in its rich functions but also in its easy installation and strong adaptability. With a compact, integrated design, it can be easily deployed without modifying manhole cover structures, making it suitable for all types of municipal covers. The device also features built-in positioning and identification functions, automatically binding geographic coordinates and road information, enabling digital resource management.

In addition, the NB-IoT communication ensures low-power operation, making it suitable for long-term deployment and environments with limited power supply. The integration of cloud platforms and mobile applications further enhances the convenience and efficiency of fieldwork and inspections.

In summary, the Smart Manhole Cover Monitoring Terminal creates an intelligent safety net where hazards are visible, management is predictive, and alarms trigger actionable responses. Whether for municipal road covers, sewer management, or flood prevention during rainy seasons, it has become an indispensable part of urban smart infrastructure.
