Problems solved by technology

[0003] However, this traditional group push control requires the operator to set the number of units controlled by the group before the control. If the pressure is insufficient, the operation must be performed again. The operation is complicated and does not have adaptive parameter setting; the operation After the completion, when the control is carried out, the group of brackets is pushed after the completion of one frame, and the pushing efficiency is low.

Abstract

The invention discloses a grouping pushing-sliding control system and method for intelligent hydraulic supports. The grouping pushing-sliding control system and method are suitable for pushing-sliding of the hydraulic supports of a fully-mechanized coal mining face under a coal mine. The system comprises distributed hydraulic support controllers and a hydraulic support remote monitoring system. Distributed hydraulic support controllers in the mining face are connected through a CAN bus and a TCP Ethernet, and connected with the hydraulic support remote monitoring system. Depending on a hydraulic support pushing-sliding curve stored in the system, the hydraulic supports can be divided into sections, parallel grouping control is performed inside each section, the number of grouped supports is set automatically depending on the driving pressure limit of a hydraulic pump, on the premise of guaranteeing drivability, the operation processes of grouping pushing-sliding control are simplified, the pushing-sliding efficiency is improved to the maximum degree, and the amount of repetition labor is reduced for an operator.

Description

technical field [0001] The invention relates to a pushing control system and method, in particular to an intelligent hydraulic support group pushing control system and method for pushing and moving hydraulic supports on a coal mine fully mechanized mining working face. Background technique [0002] The electro-hydraulic control system of the hydraulic support plays an extremely important role in the continuous coal mining operation of the fully mechanized mining face. The convenience of the electro-hydraulic control system of the hydraulic support also greatly determines the production efficiency of the underground operators. When mining, keep the straightness of the working face so that it can carry out full-cut deep mining to the greatest extent without abnormal mechanical friction with the scraper machine. The operator needs to repeatedly push the hydraulic support to make the scraper The trigger is kept straight. In order to reduce the repetitive work of the operator, th...
