Description

technical field [0001] The invention belongs to the technical field of coal shearer control, and in particular relates to an intelligent control system of a coal shearer based on an ARM microcontroller. Background technique [0002] Whether the control system is perfect and effective determines whether the shearer can work normally. The shearer is the main equipment of the fully mechanized mining face, and the normal operation of the shearer determines the production efficiency of the fully mechanized mining face. At present, the controllers of the control system of domestic shearers are basically PLCs of various brands. Although the shearers controlled by PLC have monitoring and fault diagnosis functions, they can basically meet the requirements of the shearer. However, due to the harsh working environment of the shearer, many parts, and complex structure, the driver of the shearer cannot timely control the various operating parameters of the shearer, which may cause the s...

AI Technical Summary

Problems solved by technology

However, due to the harsh working environment of the shearer, many parts and complex structures, the driver of the shearer cannot timely control the various operating parameters of the shearer, which may cause the shearer to work with a disease, and then malfunction. The operating rate of the coal mining machine must be increased, and the remote monitoring and fault diagnosis functions of the coal mining machine must be added

Also, because the labor intensity of the miners in the fully mechanized mining face is too high, it is urgent to reduce it, and it is necessary to establish an automatic fully mechanized mining face, so the shearer must have the function of memory cutting
