Working face equipment positioning system

Abstract

The invention discloses a working face equipment positioning system suitable for accurately sensing movable equipment and personnel positions in real time in the coal mining process. The system is composed of hydraulic supports, a coal mining machine, anchor points, chipless labels, a scraper conveyor, a positioning server and the like. Ultra-wideband communication is adopted between the anchor points and the chipless labels, the distances between the anchor points and the labels are measured by means of the high-time-domain resolution property of ultra-wideband, and the physical characteristics such as the speeds, movement directions and accelerations of measured objects are measured by inertia units on the chipless labels. The anchor points collect the distances between the anchor points and the chipless labels arranged under top beams of the hydraulic supports as well as movement parameters, and transmit the distances and the movement parameters to the positioning server, the movement states such as the accurate positions, movement directions and speeds of the supports and the coal mining machine are worked out, and accurate position of the equipment is achieved.

Description

technical field [0001] The invention relates to the technical field of positioning, in particular to a positioning system for working face equipment. Background technique [0002] Coal is the main energy source in my country, accounting for about 70% of the primary energy consumption structure, and more than 40% of the power generation in the world is directly produced by coal. The fully mechanized mining technology has achieved great success in the longwall working face, but the fully mechanized mining face system is the system with the most equipment, the harshest environment, and the most complicated work in coal mine production. People who have been in this harsh environment for a long time will cause great harm to their bodies. . Coal breaking, coal loading, coal transportation and hydraulic support of the shearer in the fully mechanized longwall working face have all been mechanized and automated to a certain extent. [0003] This method can realize the position perc...

AI Technical Summary

Problems solved by technology

The coal production environment is constantly changing, hydraulic support and other machinery and equipment are constantly moving with the advancement of the working face, network infrastructure and electromagnetic measurement equipment are difficult to install and maintain, a large number of ultra-broadband equipment with chips is expensive to deploy, and long-term continuous power supply is very difficult

Therefore, the existing real-time positioning systems on the market cannot meet the demand for precise positioning of intelligent coal mining in coal mines both technically and economically.
