A positioning method and system for an underground trackless vehicle

Abstract

The invention relates to the mining engineering, and particularly provides an underground trackless vehicle positioning method and system. The underground trackless vehicle positioning method comprises the steps that multiple label positions of which the intervals do not exceed the preset value along the running direction of a trackless vehicle under a mine are selected; an information label with a corresponding code is arranged on the roadway wall at each label position, and the corresponding relation is stored in a label information base; the trackless vehicle in the running process obtains the position information of the information label from the label information base according to the corresponding code by scanning the information label, and obtains the position information of the trackless vehicle relative to the information label at the moment through measuring the interval between the information label and the trackless vehicle; the position where the trackless vehicle is located at the moment is calculated by combining the position information of the information label and the position information of the trackless vehicle relative to the information label at the moment. By applying the underground trackless vehicle positioning method and system, the global coordinates of the trackless vehicle running under the mine can be easily obtained.

Description

technical field [0001] The invention relates to mining engineering, in particular to a positioning method and system for an underground trackless vehicle. Background technique [0002] In recent years, with the massive consumption of mineral resources, the situation faced by the development of surface and shallow mineral resources has become increasingly severe. It is getting worse and worse, and at the same time, there are uncertain risk factors such as roof fall, which inevitably brings certain safety and risks to the personnel engaged in mining and transportation equipment. Vigorously developing unmanned trackless transport vehicles or remote control transport vehicles has already It will become the development trend of underground mining technology in the future, and related technologies based on remote control technology, because the transmission of underground data is easily disturbed, the reliability will decline. Complexity. Therefore, vigorously developing autonom...

Problems solved by technology

Unable to achieve the positioning accuracy required for autonomous vehicles

[0004] Moreover, in vehicle positioning, the GPS technology used on the ground cannot be used. The open-pit mine can use the global satellite positioning system (GPS) to locate the vehicle, but the GPS signal cannot be received underground.

Other inertial products have the problem of error accumulation, and the error needs to be corrected absolutely. In the underground roadway environment, the existing technology cannot be accurately corrected, and the actual operation is complicated and the accuracy is not high.
