Abstract

The invention discloses an accurate positioning system and method which are used for positioning a cutting head of a heading machine in the ore extraction process. The method comprises an infrared positioning method and a magnetic field positioning method. The infrared positioning method utilizes the geometric optical principle to position, the magnetic field positioning method utilizes a machinelearning method to position, and the infrared positioning method and the magnetic field positioning method both adopt advanced positioning methods, so that the positioning precision is high, and real-time and high-precision tracking and positioning of the cutting head can be realized.

Description

technical field [0001] The invention relates to a precise positioning system and method. Specifically, the present invention relates to a compound positioning system and method for the cutting head of the roadheader composed of infrared positioning and magnetic field positioning. Background technique [0002] With the development of the mining industry, automation and intelligent tunneling and coal mining are the general trend, and the real-time positioning of the cutting head of the roadheader is the premise of intelligent tunneling. However, due to the large amount of dust generated during the working process of the roadheader, and the cutting head is sometimes buried under the slag, the traditional optical positioning method cannot adapt to such a harsh environment. The infrared positioning method can be used to complete high-precision positioning in the case of low dust, but when the cutting head is buried or blocked by the body of the roadheader, the infrared positioni...
