Design on Electric and Hydraulic Control System for Hydraulic Powered Support

According to the application status of the electric and hydraulic control system for the hydraulic powered support at home and abroad, the paper introduc ed the composition and functions of the electric and hydraulic control system for the hydraulic powered supports applied to the fully mechanized coal mining face.Also t he hydraulic powered support controller, the coal shearer position detection system, the gateway host computer and the intrinsic safe network were self-designed.The a ctual promotion application showed that the electric and hydraulic control system could make the on site control of the hydraulic powered support, the remote control of the hydraulic powered support and the automatic control of the matched equipment after the coal shearer advanced.
