Embodiment 2

[0085] Such as figure 2 As shown, in this embodiment, the detection part 2 is a hemispherical closed structure communicating with the side wall of the installation box 3, the infrared detection device in the infrared detection circuit is still installed in the detection part 2, and the two opposite sides of the installation box 3 Connected with a telescopic tube 5, the end of the telescopic tube is connected with an installation bag 4 for installing the acceleration sensor in the acceleration detection circuit. The installation bag 4 is a balloon made of a flexible material, and the acceleration sensor is installed in the installation bag 4. It can sensitively detect the change of acceleration signal caused by tiny damage. The telescopic tube 5 is connected with the installation box 2 to facilitate the wire routing between the acceleration sensor in the installation bag 4 and the MCU circuit in the installation box, and the telescopic tube 5 can be extended and shortened to f...

Embodiment 3

[0087] Such as image 3 As shown, compared with Embodiment 2, in this embodiment, another group of side walls connected to the installation bag 4 is connected with a mounting piece 6 through a telescopic tube, and the mounting piece 6 is directly bonded to the bottom of the cover, so that the touch circuit The touch device is bonded to the mounting piece 6, and the mounting piece 6 is installed near the edge of the cover, so that when the person moves the cover, he can immediately touch the touch device installed on the mounting piece 6, which is convenient for passing through in time. The touch circuit detects whether something abnormal happens to the cover.

Embodiment 4

[0089] In this embodiment, rollers are installed on the top of the cover. When people or vehicles pass by, they will be rotated by friction. The rollers are equipped with metal rotating pieces that rotate with the rollers, and there are wires on the cover. Through the hole, an error-proof circuit connected to the MCU circuit is installed on the bottom of the cover. The error-proof circuit includes two miniature mutual inductance bridges facing the metal rotary plate and an electronic logic unit connected to them. Using electromagnetic coupling, the original, When the electronic logic unit is working, the single-chip microcomputer continuously emits driving pulses, and the pulses will form space electromagnetic radiation through the LC circuit, and the radiation will be received by two miniature mutual inductance bridges. When there is no metal rotary piece close, because the transformer bridge is symmetrical The two outputs of the two are almost one after integral comparison, a...

Abstract

The invention relates to the technical field of intelligent municipal equipment, and discloses an intelligent well lid control circuit, which comprises a data processing unit, and a detection unit, apower supply unit and a data communication unit which are connected with the data processing unit separately. The power supply unit supplies power to other units. The detection unit comprises an infrared detection circuit used for infrared detection and an acceleration detection circuit used for acceleration detection. The invention further discloses a control method for the intelligent well lid.The problem that an existing intelligent well lid is high in maintenance cost is effectively solved.

Description

technical field [0001] The invention relates to the technical field of intelligent municipal equipment, in particular to a control circuit for an intelligent manhole cover and a control method thereof. Background technique [0002] Manhole cover is a municipal equipment used to cover the wellhead of various pipelines. It is not only to protect the safety of passing pedestrians, but also to beautify the appearance of the city. [0003] Because most pipeline wellheads, especially sewer wellheads, are opened on the side of the road, and even directly in the middle of the road, the manhole covers not only need to be exposed to the sun and rain in bad weather outdoors, but also trampled by pedestrians and vehicles Rolling, the wear and tear of the manhole cover is very large. And there will be a lot of manhole covers on a street, and it is impossible for the staff to find out that a manhole cover is damaged or a manhole cover is missing in time, and when a manhole cover is damag...
