Abstract

The invention discloses an automatic positioning system of an underground mining drill carriage. The automatic positioning system comprises a rock drill, a position-changing mechanism, an industrial personal computer, a sensor module for confirming a posture position of the mining drill carriage, a data acquisition card and an actuator, wherein the output end of the sensor module is connected with the input end of the data acquisition card through a cable, the output end of the data acquisition card is connected with a serial port of the industrial personal computer, the industrial personal computer is connected with the actuator through an RS-232 interface, and the actuator is connected with an electro-hydraulic proportional valve controlling actions of the position-changing mechanism through a cable. The automatic positioning system uses position-changing posture information acquired by a sensor as an initial condition, uses a blast hole instruction issued by a dispatching instruction map as a target condition, performs optimization analysis on a dynamic matrix, generates adjustment variables of the position-changing mechanism in one time, achieves a quick automatic positioning function of the underground mining drill carriage and enables the positioning of the underground mining drill carriage to be quick and accurate.

Description

technical field [0001] The invention relates to a positioning system, in particular to an automatic positioning system for an underground mining drilling vehicle. Background technique [0002] With the improvement of underground mining level, mining drilling rigs have gradually occupied an important position in mining, and the development of digital mines to improve the automation level of mining equipment has become the main development direction in the field of mining. At present, underground mining drilling rigs are mostly operated manually, and the hole layout and opening instructions are executed based on experience. The precision of hole layout is low, the precision of hole formation is poor, and the rate of waste holes is high, resulting in a huge waste of energy and resources, and at the same time poses many safety hazards. Contents of the invention [0003] The object of the present invention is to provide an automatic positioning system for an underground mining ...
