Device and system for positioning workers of fully mechanized face

Abstract

The invention provides a device for positioning workers of a fully mechanized face. The device comprises a positioning tag and a base station. The positioning tag comprises a controller, a 3D AFE and a high frequency module. The 3D AFE and the high frequency module are connected with the controller. The base station comprises a control module, a high frequency module, a low frequency module and a communication module. The high frequency module, the low frequency module and the communication module are connected with the control module. The positioning tag and the base station can be connected via communication. According to the invention, sensing and positioning of workers of the face are achieved and positioning precision reaches sub-meter level; used principles are simple and easy to achieve; the traditional fully mechanized face electrohydraulic control system technology can be upgraded, safety of the workers is ensured and safety level of the system is greatly increased; low cost is achieved and the device is applicable to hundreds of fully mechanized faces of electrohydraulic control systems in China.

Description

technical field [0001] The invention relates to a device and system for personnel positioning in a fully mechanized mining face, in particular to a system for personnel positioning using a 3D antenna. Background technique [0002] With the increasing depth of coal mining and the continuous improvement of mining technology, the fully mechanized coal mining face is gradually developing towards informatization, automation, less people or even unmanned. The large-scale adoption of large-scale mechanical equipment, information equipment, and intelligent equipment has greatly reduced the number of personnel in the coal mining face, and the functions of mining face personnel have gradually shifted from operating equipment to inspection and maintenance. To go deep into the safety of personnel, avoid equipment and personnel interference, and prevent equipment injury accidents, first of all, it is necessary to accurately locate personnel in the fully mechanized mining face, and meet t...

Problems solved by technology

However, since the above-mentioned positioning systems mostly belong to regional positioning, they cannot meet the needs of precise positioning of personnel in the working face. In addition, there are large-scale equipment such as hydraulic supports in the mining working face, and a metal semi-enclosed area is formed, where electromagnetic waves are reflected, diffracted, and shielded.
