Smart Manhole Cover Supervision Service Platform

城市现状:部分城市发生多起窨井吞人、伤人的事故、火灾、溢水、有毒气体事故。 I. Status of the city : There have been multiple accidents of swallowing and wounding manholes, fires, overflows, and toxic gas accidents in some cities.

Policy requirements: "Notice on Further Strengthening the Safety Management of Urban Manhole Covers"

Operator needs: City status: In recent years, urbanization construction has produced a large number of inspection wells, involving gas, heating, water supply, rainwater, sewage, reclaimed water, electricity, lighting, communications, information, transportation, public security transportation, radio and television, etc. In many industries, some people say that the manholes on the road are like sesame seeds on the pancakes, densely packed, and scattered, and they are widely distributed in major loops and main roads. In some places, there is almost a manhole cover next to the manhole cover. When the car starts to sway like a boat, the traffic police stop the car and think it is drunk driving, but it is actually avoiding the manhole cover.

There have been many accidents of swallowing and wounding manholes, fires, water overflows, and toxic gas accidents.
Manhole cover loss, displacement and damage are difficult to supervise and there are many hidden dangers.
How are so many manhole covers managed? Corresponding management measures have been introduced in various places to supervise and manage manhole covers in the area under their jurisdiction. However, manhole covers are still often lost, damaged, and displaced. Roads become traps, and serious safety hazards threaten pedestrians and driving safety at any time. Traditional manhole cover management is mainly based on manual inspection. On the one hand, the manhole cover loss information cannot be learned at the first time, and the person responsible for the manhole cover loss cannot be found; on the other hand, the independent manhole cover jurisdiction of various industries causes information asymmetry and relies on manual labor. Management and division management cannot effectively solve the problem; furthermore, the cost of human maintenance is high and the supervision and management of personnel is difficult. If these pain points are not solved, we will not be able to guarantee the safety of manhole covers in real time, and we will not be able to solve the hidden dangers of road safety caused by abnormal manhole covers!


Based on the above background analysis, we can make the following needs analysis:

It is imperative for operators to use intelligent manhole covers, which is both a policy requirement and a reality. Intelligent manhole cover applications will become a new era trend!

Based on the operator's industry characteristics and outstanding management issues, and taking into account issues such as anti-theft, construction costs, manhole cover maintenance, ease of operation, and product life, our demand analysis of the operator's intelligent manhole cover is shown in the figure below:






Product main functions:

NB-IOT low-power detection and transmission technology, can be customized compatible with LORA networking

APP monitoring alarm
Monitoring platform warning
