Example Embodiment

[0016] The present invention will be further described below in conjunction with the drawings:

[0017] System components: positioning anchor point 1, positioning label 5, positioning server 13. The positioning anchor point mainly completes accurate distance measurement and information access. The positioning tag is used as the object to be located, and there are mainly ultra-wideband ranging and MEMS inertial unit modules, which are used to collect the distance between the anchor point and the tag, and the movement state of the tag installation object. The positioning server realizes precise positioning based on data fusion, and is used for data processing and release, such as update calibration of anchor position, positioning tag position, alarm setting, data release, etc.

[0018] Anchor point and label structure: The structure of anchor point and label is similar, as attached figure 2 Shown. It mainly includes embedded microprocessor, mainly composed of power supply module, ...

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...
