Working face operator positioning method using auxiliary positioning nodes

Abstract

Disclosed is a working face operator positioning method using auxiliary positioning nodes. The auxiliary positioning nodes, a remote controller, a receiver and an electrohydraulic control system are provided. The auxiliary positioning nodes containing address information and having a wireless communication function are distributed at fixed positions on a working face. The remote controller has a wireless communication function and is capable of interacting with the electrohydraulic control system and controlling supports to operate, through the receiver. The receiver has a wireless communication function and is capable of receiving command information from the remote controller and forwarding the command information to the electrohydraulic system. The electrohydraulic control system has a function of controlling the supports on the working face to act. After the remote controller enters a geographic fence area specified by the auxiliary positioning nodes, the position of the remote controller determined, connection with the nearest receiver is built, the electrohydraulic system is controlled through the receiver, the supports are locked meanwhile, the operators on the working face can be automatically positioned, and safety of the operators is ensured.

Description

technical field [0001] The invention relates to a method and system for locating and ensuring safety of operators in fully mechanized mining working faces in coal mines, in particular to a high-precision personnel locating method with auxiliary locating nodes. Background technique [0002] Under the coal mine, there is a working environment controlled by remote control, which is convenient for workers to operate. However, in the current situation, for the sake of safety, the operating regulations stipulate that the operator can only operate in a limited area to avoid accidents caused by the movement of equipment in the area. Due to the harsh working environment of the underground, especially the working face, if the accurate positioning of personnel on the working face is realized by using the precise positioning technology of personnel, and the equipment in the area where the personnel are located is blocked, the working conditions of the operators can be greatly improved a...

Problems solved by technology

However, due to the complex equipment in the mining face, the small space, and the presence of a lot of dust, high humidity and other harsh environments

Radio waves are prone to phenomena such as reflection and diffraction. Traditional positioning systems that rely on field strength and flight time often have poor positioning accuracy on the working face, and it is difficult to meet the needs of precise positioning of the working face personnel.
