Embodiment Construction

[0038] The present invention will be described in further detail through implementation examples below in conjunction with the accompanying drawings, but the scope of the present invention is not limited in any way.

[0039] The positioning system in the implementation case of the present invention includes an infrared positioning module composed of multiple groups of infrared cameras, a magnetic field positioning module composed of multiple three-axis magnetic field sensors, a magnetic source that can be fixed behind the cutting head, and a composite positioning model. terminal processor.

[0040] Such as figure 1 As shown, the infrared positioning module is composed of two infrared cameras 3 and supporting data collectors, placed above the body of the roadheader; the magnetic field positioning module is composed of two three-axis digital magnetic field sensors 6, placed on both sides of the body of the roadheader; The magnetic source 2 is a circular D100X20mmN35 neodymium m...

Abstract

The invention discloses an accurate positioning system, which comprises an infrared positioning module, a magnetic field positioning module, a magnetic source capable of being fixed behind a cutting head, and a terminal processor containing a composite positioning model, the infrared positioning module is used for carrying out infrared positioning on the cutting head; the magnetic field positioning module is used for carrying out magnetic field positioning on the cutting head; when the accurate positioning system and method are used for positioning the cutting head, an accurate positioning result can be obtained; compared with a positioning result in the prior art, the positioning precision is greatly improved. And the cutting head tracking device is not influenced by working conditions and can work under complex working conditions, and the situation that tracking of the cutting head is lost is avoided.

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...
