Automatic control system of fully mechanized mining face

Abstract

The present invention provides an automatic control system of a fully mechanized mining face based on an Ethernet / IP industrial Ethernet protocol and by taking an IPC (Industrial Personal Computer) asan intelligent control center, PAC (Programmable Automation Controller) as a control main station and an embedded network controller as a substation. The intelligent control center achieves parameteroptimization of the control main station and regulates operation speeds and intelligent control of mining and transport branches of the working face; the control main station is high in timeliness and high in reliability, and can be configured to achieve full working face device automatic control; and the embedded network controller can achieve control of an emulsification pump, an atomizing pump, a filtration station and three transportation machines and can uniformly receive dispatching of the control main station.

Description

technical field [0001] The invention relates to the field of coal mining, in particular to an automatic control system for fully mechanized coal mining face. Background technique [0002] The coal mining equipment of the fully mechanized mining face mainly includes shearer, hydraulic support, scraper conveyor, reloader, crusher, pump station, down-trough belt conveyor and other equipment. At present, in the whole process of coal falling from the coal wall to being transported out of the working face in the fully mechanized mining face, the coal passes through the shearer, scraper conveyor, reloader, crusher and belt equipment in sequence. For unattended automatic mining, the control of the above-mentioned equipment is not a simple start-stop control, but automatic chain control must be realized. In the 1980s in the UK, there was a working face with no or few people on duty. That is to say, a coal mining face only needs a few people to complete the automatic connection of mi...

Problems solved by technology

However, in the actual production and operation process, this mode also has some disadvantages, such as: the communication interface and protocol standards between the subsystems are inconsistent; there are many control systems, complex levels, and real-time performance is difficult to guarantee; there are many types of equipment and maintenance work is difficult. Large amount, etc.

[0005] For example, Chinese patent application CN201510527484.X discloses a centralized control platform for large-scale equipment in fully mechanized coal mining face. If the equipment status of the subsystem is normal, the corresponding control will be carried out according to the position of the shearer. The system of this invention adds a high-speed industrial computer on the basis of the only control system of each subsystem, and the communication interface and protocol between each subsystem Inconsistent standards and complicated levels
