Coal mining machine electric control system replacement method and coal mining machine electric control system based on Internet

Abstract

The invention relates to a coal mining machine electric control system replacement method and a coal mining machine electric control system based on the Internet, and the method comprises the steps: generating a new electric control system configuration file through a far-end updating device, and building the connection with a local electric control system of a coal mining machine through the Internet; the new electric control system configuration file is sent to a local electric control system of the coal mining machine, the coal mining machine enters an electric control system updating working mode after being powered on again, and the local electric control system is updated according to the new electric control system configuration file; the system comprises a local electric control system installed on the coal mining machine and a far-end updating device used for setting machine type parameters and configuring function modules of the local electric control system, and the local electric control system is provided with an internet interface module used for interacting with the far-end updating device. And the local electric control system obtains new model parameters and function module setting information from the far-end updating device through the internet interface module. According to the invention, the electric control system of the coal mining machine can be rapidly replaced safely and efficiently.

Description

technical field [0001] The invention relates to a rapid replacement method for a local electric control system of a coal shearer and a coal shearer control system based on the Internet. Background technique [0002] Due to the different conditions of coal seam and coal quality in the coal mining face, different coal mines have different requirements for productivity, safety, production, etc., different coal mining related supporting equipment, various models of shearers, and large functional differences between each other. The electric control system of the coal machine generally provides different functional versions for different models. When the shearer leaves the factory, different versions of the electric control system will be installed according to the needs, so that the different models of the shearer can work normally under different industrial control conditions. Production. [0003] When the industrial control conditions or production requirements of the shearer ...

AI Technical Summary

Problems solved by technology

The replacement of the electric control system is a highly professional work, which is mainly carried out by the electrical engineer of the shearer manufacturer. It is necessary to update the relevant function configuration of the electric control system on site. The whole process is cumbersome, and manual operation is prone to errors

In addition, engineers have to rush from the original factory to the coal mine site, which greatly increases the time cost and economic cost
