Description

technical field [0001] The invention relates to a wireless remote centralized control system for coal mine fully mechanized mining based on an IP framework. Background technique [0002] The fully mechanized coal mining face is the core area of ​​coal mine safety production, but the working environment has always been harsh, and there are natural disasters such as gas, rock burst, coal dust explosion, water seepage, and landslides. At present, most fully mechanized mining faces have realized centralized control of three machines, that is, coal mining machine, scraper machine, and belt conveyor three-machine linkage control, but it is mainly realized through cable. Based on the harsh environment of fully mechanized mining face, wired control There are many disconnection faults and difficult maintenance, etc., which have been difficult to solve effectively. However, the control of the shearer and hydraulic support is mainly realized by means of near-end wireless remote contro...

Problems solved by technology

[0005] In foreign countries, the automatic working face of fully mechanized mining mainly relies on various sensors to realize the positioning of the shearer and automatic coal cutting. It is mainly used in mining areas with good geological conditions; mining areas with poor geological conditions are always moving due to the shearer and hydraulic support. State, various signal transmission cables are easy to break or pull off, resulting in signal interruption and unable to work

[0006] In China, the fully mechanized mining automation face has been in an experimental state. In the better fully mechanized mining face, the seamless video coverage of the fully mechanized mining face and the centralized control of the three machines have been realized, but the operating cost of the automated face is relatively high. Due to the wired connection of sensors and monitoring cameras, the movement of coal shearers and hydraulic supports and the harsh environment of coal mining, communication cables are often torn off, resulting in a sharp increase in the maintenance of cables, sensors, and cameras. Not only did it fail to reduce the number of people, but in some ways it increased the number of people, which brought a huge safety risk to the user unit. Although the country vigorously promotes unmanned automated work surfaces, due to the influence of the above factors, the promotion pressure is huge
