Abstract

The invention discloses a high-precision positioning system and method, thereby realizing positioning of the cutting head of a tunneller during ore mining. The method comprises a magnetic field positioning method. According to the magnetic field positioning method, positioning is carried out based on a machine learning method; the machine learning method is optimized and an optimal performance parameter is selected for machine learning method optimization; and an optimized magnetic field positioning model is obtained by using the optimized machine learning method. Therefore, the positioning accuracy is improved; and the real-time high-precision tracking and positioning of the cutting head in real time are realized.

Description

technical field [0001] The invention relates to a high-precision 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 po...
