Description

Technical Field

[0001] The present invention relates to the technical field of intelligent manhole covers, and more specifically, to an intelligent manhole cover and a monitoring and management system thereof. Background Art

[0002] Manhole covers are objects used to cover wellheads such as roads or deep wells in homes. Their main function is to prevent people or objects from falling and to ensure the safety of pedestrians and vehicles. As an important part of the city's underground pipeline system, manhole covers cover various wellheads such as drainage wells, cable wells, gas wells, etc. During the rainy season or heavy rain, they can also help to quickly drain ground water and prevent urban waterlogging. They also provide staff with direct access to underground facilities for daily maintenance, inspection and emergency treatment. Manhole covers can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers and polymer-based composite inspection manhole covers according to their materials, and can be divided into round manhole covers and square manhole covers according to their shapes.

[0003] At present, manhole covers, as key components of urban infrastructure, are widely distributed in streets, communities, factory areas, parks and other areas, covering sewers, communication cable wells, power inspection wells and other underground areas. The structure is mainly round or square flat plates, which are embedded in the well seat and connected and fixed to the well seat by relying on the weight of the manhole cover or a simple hinged device in combination with a limit card slot to prevent the manhole cover from accidental displacement or loss. For drainage manhole covers laid on both sides of forest roads, there are many trees on both sides of the forest roads. Under the action of wind and specific seasons, it is easy for more dead branches and fallen leaves to fall on the surface of the forest roads. Therefore, the surface of traditional manhole covers is easily covered by dead branches and fallen leaves. When encountering heavy rainfall, rainwater contacts fallen leaves, which increases the adhesion of fallen leaves to the manhole cover, causing fallen leaves to stick to the surface of the manhole cover, causing congestion of the manhole cover and causing waterlogging. Generally, it is necessary to rush to the scene manually to open the manhole cover for dredging, which is very inconvenient. In view of this, we propose an intelligent manhole cover and its monitoring and management system. Summary of the invention

[0028] Preferably, the data acquisition module is a flow sensor, which is connected to the information acquisition module. The flow sensor measures the drainage of the flow tube. When the flow sensor detects the drainage, it stores the drainage in the data storage module. By monitoring and analyzing the drainage data, it assists in judging whether the drainage of the manhole cover is normal and the operating status of the drainage system. The method for the data acquisition module to judge the drainage status of the manhole cover is as follows: Let the drainage be Q, the time be t, and within the time interval Δt, first calculate the drainage change rate A dynamic weight coefficient w(t) is introduced, which changes with time, with an initial value of w(0)=1, and is updated every fixed time interval τ according to the formula w(t+τ)=w(t)×(1-β)+γ, where β and γ are preset adjustment parameters, 0<β<1, 0<γ<1;

[0031] Preferably, the camera captures the image and analyzes it based on the pixel difference. When the coverage of dead branches and leaves exceeds the threshold, it is determined that the manhole cover surface is blocked. The determination method is as follows:

[0032] Assume that the total number of pixels on the surface of the manhole cover in the image is N, and the number of pixels judged to be covered by dead branches and leaves is n. The color weight coefficient matrix K is introduced, and its element k ij Indicates the weight of different colors in judging the coverage degree, i and j represent the position coordinates of the pixel point in the image, and calculates the weighted coverage degree where n ij Indicates the number of pixels at position (i, j) that are judged to be covered. w >C th When the manhole cover is blocked, C th ​The preset coverage threshold, and C th Dynamically adjust according to factors such as ambient light intensity and weather conditions.

[0035] Preferably, the front-end information acquisition system, back-end information processing system, central processing system and execution system are all integrated and arranged in a street light pole adjacent to the manhole cover, wherein the camera is arranged directly opposite to the top of the manhole cover, the flow sensor is arranged on the flow tube, and the execution system is an electric motor.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] 1. The present invention designs a flushing component. When the surface of the manhole cover assembly is covered with dead branches and leaves, resulting in a decrease in drainage performance, the water tank is driven by an electric motor to flip over, so that rainwater stored in the water tank is poured onto the surface of the cover assembly, and the dead branches and leaves are driven to slide down through the impact of the water flow, thereby flushing the surface of the manhole cover assembly, reducing the occurrence of a decrease in drainage performance due to the coverage of dead branches and leaves, achieving an effect of automatic cleaning of the manhole cover, and solving the problem that the surface of traditional manhole covers arranged on both sides of the forest road are easily covered by dead branches and leaves, and manual work is required to rush to the site to manually open the manhole cover for dredging.

[0038] 2. The present invention also designs a partition component. On rainy days, since both ends of the top of the clamp-shaped partition rib are constructed with clamp wings, the clamp-shaped structure formed by the clamp-shaped partition rib and the clamp wings can block the dead branches and leaves from falling on the manhole cover component, so that the dead branches and leaves are distributed in the upper layer, and rainwater slides to the bottom of the water tank for collection, avoiding the situation where the dead branches and leaves accumulate at the bottom of the water tank and cause the flushing effect to decrease. In the process of flipping, the water tank will simultaneously drive the L-shaped connecting rod to flip, so that the limit seat and the dredging rod respectively move relative to each other on the surface of the manhole cover body and inside the arc-shaped discharge groove, that is, the manhole cover body is flipped by pressing down on the limit seat, so that the sliding direction of the dead branches and leaves has a larger opening and a steeper sliding angle, thereby further improving the flushing effect. At the same time, the relative movement of the dredging rod inside the arc-shaped discharge groove can achieve a dredging effect, and can also push the dead branches and leaves, and cooperate with water flushing to ensure the stability of the automatic cleaning function.

[0039] 3. The present invention also obtains image information of the surface of the manhole cover through a camera, obtains data information of the drainage volume of the manhole cover through a flow sensor, and automatically determines whether the manhole cover is congested by combining the flow determination algorithm, the pixel difference analysis determination algorithm and the comprehensive determination algorithm therebetween, and automatically triggers the dredging action by the execution system based on the determination result, which is beneficial to improving the automation degree of the smart manhole cover and realizing intelligence. At the same time, the use of a comprehensive determination algorithm helps to improve the accuracy of judging congestion conditions. BRIEF DESCRIPTION OF THE DRAWINGS
