Embedded digitized automatic control device for coal mining machine

Abstract

The invention discloses a flush type digital self-control device of coal cutter, which comprises the following parts: upper set, lower set in connection with the upper set and peripheral equipment control circuit at core of lower set control, wherein the lower set adapts working control machine as core, which contains CPU in connection with the display data communication line through display interface and programming interface of edible controller in the lower set through serial interface and keyboard through keyboard interface; the power interface of working control machine connects the outer power through first switch power and electric filter; the output end of first switch power connects the inverter, whose high pressure power output end connects the power interface of display; the CPU stores the control program of upper set and appliance management program.

Description

technical field [0001] The invention relates to an automatic control device, in particular to an embedded digital automatic control device for a coal mining machine. Background technique [0002] In the existing technology, the application of the automatic control technology of the coal mining machine provides a new idea for the electric control system of the coal mining machine. With the rapid development of the field of industrial control and the continuous extension and expansion of the application field, the degree of automation of the domestic shearer has been improved, and the gap between the shearer and the imported shearer has been shortened. In order to meet the needs of high production and high efficiency, some advanced coal mining countries in foreign countries have continuously adopted electronic and computer technologies in monitoring and control, and correspondingly developed automatic navigation systems, monitoring and fault diagnosis systems for coal mining m...

Problems solved by technology

However, at present, the mining equipment in our country rarely uses industrial computer as the upper computer and PLC as the lower computer control equipment. Most of them use single-chip microcomputer as the control core, and the degree of automation is not high.

Although the cost is low, the anti-interference ability of the hardware equipment is not strong, the work is unstable, and it is not suitable for the harsh environment of the underground

In terms of software, the scalability, portability and versatility of the program are poor, and the integration of functions and processes is poor
