Hydraulic support automatic control system with memory function on fully mechanized coal face

Abstract

The invention relates to a hydraulic support automatic control system with a memory function on a fully mechanized coal face. The hydraulic support automatic control system comprises hydraulic supports, support controllers, a signal converter and a monitoring host, wherein one support controller is mounted on each hydraulic support, the signal converter is mounted on the hydraulic support at the end of a working face, the monitoring host is mounted in a smooth trough, and the support controllers are used for controlling the hydraulic supports and can transfer the action information of the hydraulic supports to the monitoring host of the smooth groove through the signal converter; the monitoring host comprises an action parameter memory module and an action parameter output module, and the action parameter memory module is used for sequencing the received action information of all the hydraulic supports, which is transferred from the support controllers, in chronological sequence so as to form action records of all the hydraulic supports and saving the action records; and the action parameter output module is used for outputting the action records of all the hydraulic supports in chronological sequence, the action records are transferred to the corresponding hydraulic support controllers through the signal converter, and then the automatic control of the hydraulic supports is realized.

Description

technical field [0001] The invention relates to an automatic control system of a hydraulic support with a memory function in a fully mechanized mining face, in particular to a comprehensive system for automatic control of a hydraulic support in a fully mechanized mining face in a coal mine and a control method thereof. Background technique [0002] The fully mechanized mining face is composed of multiple hydraulic supports and other equipment. The advancement of the working face is completed by the action of the hydraulic support. In the fully mechanized mining face, the hydraulic support of the front drum of the coal mining machine should be retracted to facilitate coal mining. When cutting coal by machine, the hydraulic support behind the front drum of the shearer should extend out to support the top plate of the shearer, the hydraulic support behind the shearer should be moved, and the hydraulic support after the shift should be pushed, so that Realize the movement of the...

AI Technical Summary

Problems solved by technology

Generally, the program control of the hydraulic support is used to realize the group-retracting side panels, group-extending side panels, group-moving frames and group-pushing actions of the hydraulic support. In the process of production and use, because the conditions of the top and bottom plates of the working face are changing at any time, and the inclination angle and pitch state of the working face are different, it is difficult for the solidified automatic program to adapt to the changing working face conditions. Therefore, the automatic control program of the working face has poor adaptability. In particular, the automatic frame moving program is difficult to popularize and apply, and most of them are manually operated through the frame controller to realize the frame moving action of the hydraulic support, which has become the main bottleneck restricting the application of the electro-hydraulic control system of the hydraulic support.
