Problems solved by technology

At present, there are many fully mechanized mining (opening) working faces equipped with electro-hydraulic control systems. However, on the one hand, due to the changing conditions of the production site, it is almost impossible to fully realize the automatic operation of the hydraulic support without manual intervention. The working process of the bracket is often completed by manual operation of the electro-hydraulic control keyboard, or the automatic work process is supplemented by the intervention of some actions through the manual operation of the electro-hydraulic control keyboard; Technology, one of the functions of the hydraulic support is to provide a safe working space for the workers in the working face. In fact, the fully mechanized mining (opening) working face equipped with an electro-hydraulic control system implements automatic production. Potential for harm, something the industry has been concerned about
Especially in the medium-thick and thin coal seam and thin coal seam working face, the working space is narrow, and the hydraulic support is controlled by manual direct operation of the electro-hydraulic control keyboard. Second, the labor intensity is high
At the same time, due to the difficulty and slow movement of personnel, the personnel in the working face are between the hydraulic support and the scraper conveyor during the production process. During the automated production process, the hydraulic support is more likely to cause personal injury

The control device comprises a hydraulic bracket electro-hydraulic control host and a plurality of hydraulic bracket controllers and further comprises a non-blind area communication network arranged in a fully mechanized mining face, wherein the non-blind area communication network comprises a personnel positioning wireless transceiver or a personnel positioning wireless transmitter, a handheld remote control wireless transceiver, at least two wireless transmitting and receiving base stations and a wireless network control system host; the personnel positioning wireless transceiver or the personnel positioning wireless transmitter is carried by personnel in the mining face; the at least two wireless transmitting and receiving base stations are mounted on a hydraulic bracket or a scraper conveyor; the wireless network control system host is mounted in a underground coal face gateway; and the wireless network control system host is used for managing the whole non-blind area communication network. The hydraulic bracket control device with the personal safety protection function, disclosed by the invention, is a failure safe type protecting device, which realizes safety protection of full face personnel.

Description

technical field [0001] The invention relates to the technical field of hydraulic support control, in particular to a hydraulic support control device with a personal safety protection function and a control method thereof. Background technique [0002] Hydraulic support is one of the most important supporting equipment in coal mine fully mechanized mining (opening) working face, and electro-hydraulic control is the highest configuration of hydraulic support control at present. The hydraulic support of fully mechanized mining (opening) working face of coal mine adopts electro-hydraulic control system, which creates conditions for realizing the production automation of fully mechanized mining (opening) working face. At present, there are many fully mechanized mining (opening) working faces equipped with electro-hydraulic control systems. However, on the one hand, due to the changing conditions of the production site, it is almost impossible to fully realize the automatic opera...
