Study on Automatic Following Technology of Electric and Hydraulic Control System Applied in Hydraulic Powered Support

The paper analyzed the released condition and method of the following automatic for the electric and hydraulic control system of the hydraulic powered s upport.A modeling was simplified for the following process .Eight following automatic position parameters and the following automatic procedure tables of six processes were defined.In the actual application,the cases of the full cutting depth bidirectional coal mining technology realized in the electric and hydraulic contral system of hydr aulic support were provided.A electric and hydraulic control system of the powered supports based on the double RS485 bus was established on the simulation platform in the lab.And the automatic following demonstration was realized with a program.The results could provide the theoretical references to the popularization of the followi ng automation of the powered support electric and hydraulic control system.
