[0002] With the development of urban infrastructure, there are more and more urban wells for rainwater, sewage, telecommunications, electricity, gas and other industries. Road manhole covers have become an important part of urban infrastructure. During use, manhole covers may become loose, damaged, opened or stolen. If the engineering staff cannot maintain them in time, the manhole covers installed in the designated locations will not work, causing uneven roads, affecting the use of pedestrians and vehicles, and thus affecting travel safety.

[0003] A manhole cover monitor disclosed in the prior art CN 217442599 U is used to monitor the parameters of the manhole cover, including a shell, a cover plate, a base, a magnet and other components. Although the utility model sets a base including a magnet on the manhole cover monitor, so that one end of the base relies on the magnet to absorb the manhole cover, and the other end is connected to the shell, so that the manhole cover and the manhole cover monitor are fixed together. In this way, the installation steps of the manhole cover monitor can be greatly simplified and the installation time can be saved, but the utility model cannot monitor the damage of the manhole cover, resulting in limited monitoring capabilities, and the utility model is only fixed on the manhole cover by magnet adsorption, and may fall off the manhole cover when the manhole cover shakes, causing the loss of the monitor, so there is still room for improvement.
