Abstract

The invention discloses a coal flow monitoring system based on a laser radar and speed information. The coal flow monitoring system comprises a belt conveyor, a two-dimensional radar which is installed above the belt conveyor and is used for obtaining a cross section outline curve of a coal flow, a speed sensor which is installed on a lower belt position of the belt conveyor and is used for obtaining the belt running speed and a coal flow calculation terminal used for solving and completing calculation of coal flow through integral. According to the coal flow monitoring system based on the laser radar and the speed information, a laser radar technology and an image processing technology are combined, the coal flow of the coal downhole belt conveyor can be automatically measured, essential technical support is provided for computing the coal flow of the coal downhole belt conveyor, and the method has significant importance in coal flow statistics.

Description

technical field [0001] The invention relates to the field of coal mine production state monitoring, in particular to a coal flow monitoring system based on laser radar and speed information. Background technique [0002] The coal flow monitoring of the belt conveyor in the coal mine is the premise of automatic production and control in the coal mine, so the coal flow monitoring of the belt conveyor in the coal mine is very necessary. Therefore, the coal flow monitoring system based on laser radar and speed information is used to monitor the coal flow of the belt conveyor in real time. According to the monitoring results of the coal flow, the opening of the gate under the warehouse is adjusted so that the belt conveyor does not stop flowing. It is of great significance to realize the automatic monitoring of the flow rate of the belt conveyor and the automatic control of the feeding system. [0003] At present, the coal flow monitoring system based on laser radar and speed in...
