Abstract

The invention discloses a compound positioning system and method for a tunneling machine cutting head based on infrared and magnetic field positioning. A magnetic field positioning part of the systemfirstly traverses a workspace through the cutting head with a fixed permanent magnet, an infrared positioning module records a three-dimensional space position in real time, the magnetic induction intensity of the corresponding position is recorded by a magnetic field sensor to obtain training data, and then a magnetic field positioning model is constructed by a depth learning algorithm. Through the combination of infrared positioning and magnetic field positioning, a low visibility environmental impact caused by high concentration of dust and the influence of ferromagnetism of a tunneling machine body when a tunneling machine works are overcome, and the real-time positioning problem of the tunneling machine cutting head is solved.

Description

technical field [0001] The invention relates to a positioning system and method for a cutting head of a roadheader. Specifically, the present invention relates to a composite positioning system and method for cutting heads of roadheaders, which are composed of infrared positioning based on geometric optics and magnetic field positioning based on deep learning. 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 cutti...
