Problems solved by technology

If the manhole cover is frequently rolled over many times, the manhole cover will be damaged to varying degrees, which will affect road traffic and bury safety hazards at the same time
[0004] In the prior art, real-time monitoring of the use of the manhole cover in use, such as whether it is damaged, is realized by installing a detection device under the manhole cover. However, the pressure and sloshing generated by the manhole cover cannot be detected

Embodiment Construction

[0027] The following is attached figure 1 The technical solution of the present invention is further described.

[0028] A manhole cover movement sensor based on the Internet of Things includes a pressure detection unit, a displacement detection unit, a control unit, a displacement compensation unit and an alarm unit.

[0029] The pressure detection unit obtains the pressure information on the surface of the manhole cover, and transmits the pressure information to the control unit.

[0030] The displacement detection unit obtains the displacement information generated by the manhole cover, and transmits the displacement information to the control unit. The displacement information refers to the distance information of the manhole cover from its original position.

[0031] The control unit reads the pressure information, analyzes and judges whether the displacement information is within the required range, and the required range refers to all values ​​between the maximum and m...

Abstract

The invention discloses a well lid abnormal movement sensor based on the Internet of Things. The well lid abnormal movement sensor comprises a pressure detection unit, a displacement detection unit, acontrol unit, a displacement compensation unit and an alarm unit. The pressure detection unit and the displacement detection unit are used for detecting the pressure borne by the well lid and the generated displacement respectively, the control unit is used for analyzing and judging whether the pressure and the displacement are within the normal range of the well lid or not, controlling the displacement compensation unit to conduct displacement compensation and controlling the alarm unit to send out an alarm signal, and thus the automatic monitoring effect is achieved.

Description

technical field [0001] The invention relates to the technical field of automatic control of manhole covers, in particular to a manhole cover abnormal movement sensor based on the Internet of Things. Background technique [0002] Manhole covers are used to cover roads or deep wells in homes to prevent people or objects from falling. On urban roads, most of the manhole covers are not tightly attached to the road surface. When the vehicle is overrun, the tires will collide with the manhole covers. After long-term use, the manhole covers will be damaged to a certain extent. [0003] When the tire presses over the manhole cover, it will exert a certain pressure on the manhole cover. When the pressure is too high, it will cause a certain degree of impact on the manhole cover. Since the manhole cover is not tightly attached to the road surface, the manhole cover will shake and cause a small amount of displacement. If the manhole cover is frequently rolled over many times, the man...
