Embodiment approach 1

[0032] figure 1 It is a schematic diagram showing the structure of a distance measuring device with a detection surface, a line light source and a CCD smart camera according to an embodiment of the invention. When the conveyor belt width of the belt conveyor is 2m and the conveyor belt running speed is 5m / s, its main technical indicators are:

[0033] Power supply: ~220V 10% 50HZ

[0034] Signal transmission distance: Infrared CCD camera output signal Optical fiber transmission: 1Km

[0035] Working temperature: 30°C

[0036] The coincidence between the detected volume and the actual volume: 98%

[0037] Image detection resolution: 1.5mm

[0038] Imaging frame frequency: 30 frames / s

[0039] Conveyor belt width: 2m

[0040] Detect the running speed of the conveyor belt: 5m / s.

[0041]The working process of the above-mentioned method for visually scanning and measuring the amount of coal conveyed by a belt conveyor is as follows: install a line light source on the center...

Embodiment approach 2

[0048] When the width of the conveyor belt of the belt conveyor is less than 1.5m and the running speed of the conveyor belt is lower than 5m / s, the main technical indicators of the device are:

[0049] Power supply: ~220V±10%50HZ

[0050] Signal transmission distance: Infrared CCD camera output signal Optical fiber transmission: 1Km

[0051] Working temperature: 30°C

[0052] The coincidence between the detected volume and the actual volume: 98%

[0053] Image detection resolution: 1.5mm

[0054] Imaging frame frequency: 30 frames / s

[0055] Conveyor belt width: 1.2m

[0056] Detect the running speed of the conveyor belt: 3.5m / s.

[0057] The speed sensor detects the running speed of the conveyor belt through the TCF-142RS485 / optical fiber module 5 using optical fiber transmission, and then through the TCF-142 optical fiber / RS232 module 6 through the RS-232 interface 11 to the host computer. Others are the same as Embodiment 1.

Abstract

The invention discloses a visual scanning and distance measuring method for coal quantity passing belt conveyer, which belongs to the technical field of online automatic detection of coal mine equipment. The method features the following steps: obtaining the outline drawing of a reference object through a line light source and a CCD camera; transmitting the data acquired by the camera to a position machine; determining the cross-sectional area of the materials passing the detection surface after image analysis; and conducting scanning and distance measuring to the coal quantity passing the belt obtained by time integral within a testing time. The method provided by the invention distinguishes itself from other measuring methods in China's coal industry by low cost and a simple structure. The adoption of line light source to project a contour of a testing position on a passing belt means that even under complex working conditions with dim light and enormous dust, the method can work free from interference to achieve high measuring accuracy and determine the flow of coals passing the belt more accurately.

Description

technical field [0001] The invention relates to a visual scanning and ranging detection method for the amount of coal conveyed by a belt conveyor, which belongs to the technical field of automatic online detection of coal mine equipment, and specifically relates to a contour map of a reference object obtained by a line light source and a CCD camera. The collected data is transmitted to the upper computer, and the cross-sectional area of ​​the material passing through the detection surface is determined through image analysis, and the conveying volume of the material conveyed by the conveyor belt within the measurement time is obtained by integrating the time. In a more complex working environment, it is possible to more accurately measure the flow of materials conveyed by the conveyor belt. Background technique [0002] The belt conveyor is the main transportation equipment in coal mine production at present. It undertakes the important task of conveying materials from the m...
