Coordinated automatic control system and method for fully mechanized mining face equipment

Abstract

The invention discloses a fully-mechanized coal mining face equipment cooperative automatic control system and method. A coal mining machine-mounted module, a scraper conveyor-mounted module and a crusher-mounted module are connected with one another through electric signals of wireless receiving and transmitting modules so as to acquire real-time parameters of each set of equipment and transfer the parameters to one another, and the controllers of the equipment circularly and automatically adjust the parameters of the equipment, and therefore, the automatic control system can achieve an optimal operation state; and when the coal carrying capacity of a scraper conveyor is too high or too low, the automatic control system of the invention can automatically adjust the parameters of a coal mining machine, the scraper conveyor and a crusher so as to prevent the blockage of a fully-mechanized coal mining face and improve the coal mining efficiency of the fully-mechanized coal mining face. With the system and method of the invention adopted, on the one hand, the physical labor of workers can be reduced, the personal safety of the workers can be ensured, humanized and unmanned mechanized mining requirements can be satisfied, and on the other hand, delay and misjudgment can be eliminated, the device will not always be in a maximum power output state; and therefore, high yield, high efficiency and low energy consumption can be achieved.

Description

technical field [0001] The invention relates to the field of coal mining technology, in particular to a fully-mechanized mining face equipment cooperative automatic control system and method. Background technique [0002] Coal mining machine is one of the important equipment to realize the mechanization and modernization of coal mine production. Mechanized coal mining can reduce physical labor and improve safety, and achieve the purpose of high output, high efficiency and low consumption. The scraper conveyor is pulled by a scraper chain. In the current coal mining face, the function of the scraper conveyor is not only to transport coal and materials, but also the running track of the coal mining machine, so it has become an indispensable part of the modern coal mining process. main equipment. If the scraper conveyor can keep running continuously, the production can go on normally; otherwise, the entire coal mining face will show a shutdown state, which will interrupt the e...

AI Technical Summary

Problems solved by technology

[0004] (1) It is mainly operated by workers. On the one hand, it is not conducive to the personal safety of workers, and does not meet the requirements of less-manned and unmanned fully mechanized mining. On the other hand, there are great external environmental factors, which may cause misjudgment;

[0005] (2) There is a delay in the operation of workers, and the equipment cannot be operated in time, which affects the production efficiency of the coal mine;

[0006] (3) When the workers operate negligently, the equipment may be kept at the maximum output power state, wasting energy and causing economic loss of coal mines
