摘要
A kind of support and control device that is used for controlling mine work plane support unit motion and driving has a plurality of control modules, each support unit respectively on the place and on the function corresponding to the control module (backplate controller) in these control modules.Each backplate controller comprises a multi-channel radio transceiver, with the operating process that disperses, movably operating means sends simultaneously and receives in, a backplate controller in described a plurality of backplate controllers receives control data and sends survey data and status data by this wireless set.Described backplate controller is programmed in the following manner: when the control signal that transmits by radio by corresponding to the code word of the backplate controller that is called when shared, this control signal can only be converted into the function of this support unit.The backplate controller preferably is connected by two bus conductors (58,59) each other, is used for the transfer of data of input is arrived all backplate controllers.Each backplate controller has an amplifier, is used to upgrade the signal that transmits by bus conductor.
