Intelligent manhole cover monitoring system solution

The smart manhole cover sensor is a new type of smart sensor based on the Internet of Things technology. This product uses wireless communication modules and high-precision pressure sensors to achieve remote communication with the monitoring center to solve the problem of manhole cover management in the city. This product combines sensors and wireless transmission modules, installs a dedicated wireless communication module on the smart manhole cover, uses the dedicated communication module to collect manhole cover status information, and uploads the data to the monitoring center through the wireless transmission module. When the manhole cover is abnormal, the monitoring center can notify relevant personnel through SMS, phone calls and other methods to prevent people and vehicles from entering the manhole by mistake and causing safety accidents.
Manhole covers are the most common safety hazards on urban roads. Due to poor quality of manhole covers and unreasonable installation, the number of manhole cover theft cases is increasing every year. In order to reduce the occurrence of such cases and maintain social security, relevant national departments have successively issued a number of policies and regulations to uniformly supervise manhole covers. However, these measures have not completely eliminated the “blind spots” and “dead corners” in manhole cover management.
The smart manhole cover sensor is a sensor that can monitor changes in the state of manhole covers. It is based on traditional manhole cover detection and realizes remote communication with the monitoring center by adding a wireless communication module.

This system adopts embedded development technology, with low power consumption as its main feature. It uses high-precision pressure sensors, displacement sensors and other measuring elements to conduct all-round detection of manhole covers, and has the characteristics of low power consumption, strong anti-electromagnetic interference, and high reliability. The system has the ability of intelligent judgment and realizes real-time monitoring of the status of manhole covers. The system also has emergency alarm function and fault warning function, which can send alarm information when the manhole cover is abnormal. When the manhole cover is in an abnormal state, it can automatically send alarm information to mobile phone text messages or phone calls to notify relevant personnel. This system can be widely used in urban management, security and other fields.
The wireless intelligent manhole cover level detector IDM-400-C detects whether the manhole cover has been tampered/stolen or tilted. It can prevent the metal cover and the valuable assets underneath (such as optical cables, communication equipment, etc.) from being stolen. The manhole cover monitoring sensor has the characteristics of small size and long communication distance. It uses the LoRaWAN or NB-IOT protocol standard to communicate with the LORAWAN gateway or base station, realizing the application functions of multi-information distance recognition, automatic information upload, alarm location, and cloud platform high-speed data processing. Angle detection flip (angle greater than 20°) changes, actively reporting to the base station water immersion monitoring liquid level detection range 30-500mm: contact electrode water immersion alarm trigger. The wireless intelligent manhole cover detector includes manhole cover opening and low battery alarm. The timed reporting function can be set, including manhole cover opening, battery power, signal strength, etc.
Through the introduction of smart manhole cover sensors, we can see that the main function of smart manhole cover sensors is to monitor the changes in the state of the manhole cover in real time. If an abnormal situation occurs, an alarm message will be sent in time. Using sensor technology, Internet of Things technology, intelligent algorithms and other means to monitor and manage manhole covers in real time can achieve remote monitoring and management of manhole covers.
In cities, various pipelines crisscross the road, bringing convenience to people’s travel and life. But at the same time, if we neglect management or failure occurs, it will cause serious consequences. For example: gas pipeline leakage, communication cable damage, cable well fire, etc.
Although these accidents all happen in inconspicuous corners, if these problems are not dealt with in time, the consequences will be disastrous. Therefore, the application of smart manhole cover sensors in cities can not only improve the safety of urban roads, but also provide people with a more comfortable and convenient living environment. Therefore, the application of smart manhole cover sensors in cities is of great significance.
