Precise positioning technology of operator of remote-controlled electro-hydraulic control system

In view of problem that operator of remote-controlled electro-hydraulic control system is easy to malfunction while controlling the support action, precise positioning technology of operator of remote-controlled electro-hydraulic control system was studied combined with actual situation of fully mechanized coal mining face, and the positioning accuracy was improved to 1.5 m by RSSI information normalization, field strength zoning and optimal sensor positioning to meet requirements of remote-controlled electro-hydraulic control system.
