Embodiment 1

[0048] The embodiment of the present invention proposes a positioning method for underground trackless vehicles, see figure 1 , the method includes:

[0049] Step 101: select a number of label positions whose spacing does not exceed a predetermined value along the trackless vehicle traveling direction in the mine;

[0050] Step 102: setting a corresponding coded information label on the roadway wall at each label position, and storing the corresponding relationship in the label information database;

[0051] Step 103: The moving trackless vehicle scans the information label, obtains the position information of the information label from the label information library according to the obtained corresponding code, and obtains the trackless vehicle at that time by measuring the distance from the information label Position information relative to the information label;

[0052] Step 104: Combining the position information of the information tag and the position information of the...

Embodiment 2

[0097] The embodiment of the present invention proposes a positioning system for underground trackless vehicles, see Figure 7 , the system consists of:

[0098] The coded information label module 701 is used to select a number of label positions whose spacing does not exceed a predetermined value along the direction of trackless vehicle travel underground, and to set a corresponding coded information label on the roadway wall of each label position, and place it The corresponding relationship is stored in the tag information database;

[0099] The scanning distance detection module 702 is used for the trackless vehicle in motion to scan the information label, obtain the position information of the information label from the label information library according to the obtained corresponding code, and measure the distance between the information label and the information label. Get the position information of the trackless vehicle relative to the information tag at that moment;...

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...
