Tracked ore transfer car positioning system and positioning method thereof

Abstract

The invention discloses a tracked ore transfer car positioning system and a positioning method thereof. The tracked ore transfer car positioning system comprises an ore unloading machine, tracks located on the front side of the ore unloading machine, and multiple connected ore transfer cars walking on the tracks. An optical grating transmitter is arranged at the positions, located at the bottom ofthe ore unloading machine, of one sides of the tracks, an optical grating receiver corresponding to the optical grating transmitter is arranged on the other sides of the tracks, a light curtain is formed by optical gratings transmitted by the optical grating transmitter, and the width of the light curtain from left to right is larger than the lengths of the ore transfer cars. The optical gratingreceiver is connected with a communication interface. The communication interface is connected with a data processor. The data processor is connected with a controller. The controller controls the operating states of the ore transfer cars. The tracked ore transfer car positioning system and the positioning method are combined, the problem about precise positioning of the tracked ore transfer carsis effectively solved, the production efficiency is improved, and production automation is promoted.

Description

technical field [0001] The invention belongs to the field of mine transportation, and in particular relates to a positioning system and a positioning method for rail mine vehicles. Background technique [0002] The rail mine car has become the most important means of transportation for underground transportation in mine production because it can better adapt to changes in roadway curvature. It is very important that there are many ways to locate mine trucks. The commonly used ones are RFID tag positioning and encoder positioning. However, RFID tag positioning has a large error problem, and its positioning error can reach up to 0.6m, which leads to There is always an uncertain error in the positioning of the RFID card, which cannot meet the requirements of precise positioning; the positioning of the encoder will cause a positioning error due to the displacement caused by the skidding of the mine truck. The error generated by the above positioning method usually needs to be ad...

[0002] The rail mine car has become the most important means of transportation for underground transportation in mine production because it can better adapt to changes in roadway curvature. It is very important that there are many ways to locate mine trucks. The commonly used ones are RFID tag positioning and encoder positioning. However, RFID tag positioning has a large error problem, and its positioning error can reach up to 0.6m, which leads to There is always an uncertain error in the positioning of the RFID card, which cannot meet the requirements of precise positioning; the positioning of the encoder will cause a positioning error due to the displacement caused by the skidding of the mine truck. The error generated by the above positioning method usually needs to be adjusted and corrected manually , labor-intensive, time-consuming and inefficient, which has a serious impact on automated production and hinders the improvement of production efficiency
