TIMBERING AND WALLING CONTROL FOR CONTROLLING THE MOVEMENTS OF TIMBERING AND WALLING UNITS IN THE COAL FACE OF A MINE

摘要

A kind of support and control device that is used for controlling mine work plane support unit motion, have a central controller (50) and a plurality of control module (34), each support unit respectively on the place and function on corresponding to the control module (backplate controller) in these control modules.Described backplate controller is by two bus conductors (58,59) be connected with central controller, and interconnect, by described bus conductor, for input control order, each backplate controller can be called by central controller or adjacent backplate controller.Each backplate controller is so programmed: transmit by bus conductor, can be transferred to this backplate controller to carry out by the shared control instruction of the code word that corresponds respectively to the backplate controller that will call.Ei backplate controller has a switch element (53), can be by this switch element with the bus conductor in the backplate controller separately.By second bus conductor (parallel bus) of same kind, transmit, further be not forwarded to adjacent backplate controller by the shared signal of the code word that corresponds respectively to the backplate controller that will call.
