Description

technical field [0001] The invention relates to a real-time self-checking pressure power generation smart manhole cover, which belongs to the field of smart cities. Background technique [0002] With the rapid progress of urban infrastructure construction, people enjoy the convenience brought by development, and urban road construction is also proceeding in an orderly manner. However, in urban roads, there are a large number of manhole cover loss and manhole cover damage problems. The lack of manhole cover is usually caused by human theft or construction personnel not installing it in time. On the road where large vehicles pass, due to the severe overload of the vehicle, the pressure of the manhole cover exceeds the design capacity of the manhole cover, causing the manhole cover to be crushed. During the driving of road vehicles, car crashes and fatal accidents are often caused by manhole cover problems, and vehicle drivers are very afraid of manhole cover problems. Now the...
