Fully mechanized mining three-machine cross-platform remote real-time motion tracking system and method

Abstract

The invention discloses a three-machine cross-platform remote real-time motion tracking system and method for fully mechanized mining. The system comprises a sensor group, a PLC group, an industrial field server and a client computer, the sensor set comprises a hydraulic support stand column pressure sensor. A hydraulic support stand column displacement sensor, a hydraulic support pushing displacement sensor, a hydraulic support pushing pressure sensor, a coal mining machine walking displacement encoder, a coal mining machine left rocker arm inclination angle sensor, a coal mining machine right rocker arm inclination angle sensor, a first coal mining machine stroke limiting switch and a second coal mining machine stroke limiting switch. The PLC set comprises a first hydraulic support PLC module, a second hydraulic support PLC module, a third hydraulic support PLC module, a fourth hydraulic support PLC module and a coal mining machine PLC module. The problem that ground monitoring depends on a working face video for a long time is solved, and judgment of an operator on the running state of production equipment cannot be affected by severe environments such as high dust and low illumination of the working face.

Description

technical field [0001] The invention belongs to the technical field of coal mine intelligent mining, and in particular relates to a cross-platform remote real-time motion tracking system and method for three fully-mechanized mining machines. Background technique [0002] Coal is the main energy source in my country, and safe, intelligent, green and efficient mining is the main direction for the development of coal mines in my country. my country's high-mining coal seams account for more than 45% of the total coal resource reserves, but mining is difficult due to factors such as high coal mining height, easy coal walls, and high dust concentration. Therefore, the monitoring and control of the three machines in the fully mechanized mining face of the coal mine is related to the safe production of the entire coal mining enterprise. The visual remote intervention control system of the fully-mechanized three-machine equipment uses the video surveillance of the working face as a ...

AI Technical Summary

Problems solved by technology

In recent years, with the advancement of "Industry 4.0" and "Internet + Smart Coal Mine", this technology has become more and more perfect, but there are still the following technical deficiencies: the existing fully-mechanized mining face visualization mainly relies on video technology, but the production of fully-mechanized three-machine The dust concentration on the job site is high, the visibility is low, the environment is harsh, and the video monitoring effect is poor. Remote workers cannot accurately obtain the working status of the equipment; Personnel cannot quickly and intuitively obtain the status of equipment operation, which affects the timeliness and accuracy of decision-making; the existing coal mine fully mechanized mining face monitoring system is a typical client / server architecture system, which cannot be used for remote mobile monitoring across platforms. Lack of agility, affecting the flexibility of on-site production decisions
