Embodiment Construction

[0027] A further detailed description of the technical solutions of the present invention will be described in conjunction with specific embodiments and drawings.

[0028] Append figure 1 The intelligent depth detector used in a coal flow detection method based on a surface laser radar is attached to the center position of the belt conveyor through the L-shelf.

[0029] S1: figure 2 As shown: The laser radar column mirror emits 176 beam laser light at an angle of 0.5 degrees, and the 176 bundle laser light is shown in a fan-shaped distribution. The main controller of the laser radar is sequentially measured by a 176-bundled laser at 200 ms. Actual distance d;

[0030] S2: Judgment the belt conveyor belt width: compare the first bundle laser light and the second beam laser light, the first bundle light line and the 175 beam, the second beam laser light and the third beam light line are compared, the 175 beam light Compared to the 174th beam, it is contrast to the intermediate beam....

Abstract

The present invention is a coal flow detection method for accurately analyzing the amount of coal carried on a belt conveyor. The laser radar ranging technology is applied to the field of coal mine automation. The laser beam emitted by the column and the belt shape data returned by the lidar are calculated by a certain processing algorithm to obtain the average thickness of the coal on the belt, and the coal flow is calculated according to the formula. It overcomes the problems of large error in weighing adjustment during the transmission process of the traditional coal belt control intelligence, complicated construction and installation, and easy damage. It realizes the direct detection of coal on the conveyor belt and improves the automation level of the coal mining industry.

Description

Technical field [0001] The utility model relates to the field of coal mine automation, and in particular to a coal stream detection method for accurate analysis of coal amounts on the belt conveyor. Background technique [0002] In the coal industry, the belt conveyor has become the main products of the main raw coal production and transportation. This transportation system is responsible for the transfer of underground coal storage coal bins, but causes the coal mine of the conveyor due to the imbalance of coal mines. The amount cannot be kept stable, causing the belt conveyor to be in a non-optimal operating state of the "Malaysia trolley", resulting in a large amount of electrical energy consumption. Therefore, according to the problem of the tape conveyor speed of the coal, it is an urgent need to solve, and the key and premise of solving this problem is to achieve the test of the tape conveyor coal, and the current transport of the material is generally The weight is carried...
