Abstract
Abstract A redundant remote control system for use on a continuous miner having a radio remote control system for the remote control of a continuous miner. The radio remote control system having switches, a multiplexer, a radio transmitter, a radio receiver, a demultiplexer, and a radio interface. The redundant remote control system includes a second system for controlling the same continuous miner, and includes a second transmitter, a second multiplexer, a second receiver, and a second demultiplexer. The second system may be a radio, a fiber optic or electrical cable remote control system.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
186 words
A method of remote control for use on a continuous miner comprising the steps of, providing for the remote control of a continuous miner a first system having at least one switch, a first multiplexer, a first transmitter, a first receiver, a first demultiplexer and a first continuous miner interface, positioning said switch, said first multiplexer, and said first transmitter in an operator station located remote from said continuous miner, connecting said first receiver and said first demultiplexer to said first continuous miner interface on said continuous mining machine, translating a signal from said first demultiplexer by said continuous miner interface into miner functions, providing for the remote control of said continuous mining machine a second system having a second multiplexer, a second transmitter, a second receiver and a second demultiplexer, arranging said second multiplexer and said second transmitter in said operator station, connecting said second receiver and said second demultiplexer to said continuous miner, and interconnecting said second demultiplexer with said continuous miner interface to receive a signal from said second system to initiate miner functions in the event of failure of said first system.
Claim 2
Independent Claim
186 words
A method of remote control for use on a continuous miner comprising the steps of, providing for the remote control of a continuous miner a first system having at least one switch, a first multiplexer, a first transmitter, a first receiver, a first demultiplexer and a first continuous miner interface, positioning said switch, said first multiplexer, and said first transmitter in an operator station located remote from said continuous miner, connecting said first receiver and said first demultiplexer to said first continuous miner interface on said continuous mining machine, translating a signal from said first demultiplexer by said continuous miner interface into miner functions, providing for the remote control of said continuous mining machine a second system having a second multiplexer, a second transmitter, a second receiver and a second demultiplexer, arranging said second multiplexer and said second transmitter in said operator station, connecting said second receiver and said second demultiplexer to said continuous miner, and interconnecting said second demultiplexer with said continuous miner interface to receive a signal from said second system to initiate miner functions in the event of failure of said first system.
Claim 3
Dependent Claim
26 words
The method of remote control for use on a continuous miner as in claim 1 wherein, providing a radio remote control system as said first system.
Claim 4
Dependent Claim
26 words
The method of remote control for use on a continuous miner as in claim 2 wherein, providing another radio remote control system as said second system.
Claim 5
Dependent Claim
27 words
The method of remote control for use on a continuous miner as in claim 2 wherein, providing an electrical cable remote control system as said second system.
Claim 6
Independent Claim
182 words
A method of remote control for use on a continuous miner comprising the steps of, providing for the remote control of a continuous miner a first system having at least one switch, a first multiplexer, a first transmitter, a first receiver, a first demultiplexer and a first continuous miner interface, positioning said switch, said first multiplexer, and said first transmitter in an operator station located remote from said continuous miner, connecting said first receiver and said first demultiplexer to said first continuous miner interface on said continuous mining machine, providing for the remote control of said continuous mining machine a second system having a second multiplexer, a second transmitter, a second receiver and a second demultiplexer, arranging said second multiplexer and said second transmitter in said operator station, connecting said second receiver and said second demultiplexer to said continuous miner, providing as said second system, a fiber optic remote control system including a fiber optic cable remotely connecting said second transmitter with said second receiver, and transmitting light impulses from said second transmitter through said fiber optic cable to said second receiver.
Claim 7
Independent Claim
182 words
A method of remote control for use on a continuous miner comprising the steps of, providing for the remote control of a continuous miner a first system having at least one switch, a first multiplexer, a first transmitter, a first receiver, a first demultiplexer and a first continuous miner interface, positioning said switch, said first multiplexer, and said first transmitter in an operator station located remote from said continuous miner, connecting said first receiver and said first demultiplexer to said first continuous miner interface on said continuous mining machine, providing for the remote control of said continuous mining machine a second system having a second multiplexer, a second transmitter, a second receiver and a second demultiplexer, arranging said second multiplexer and said second transmitter in said operator station, connecting said second receiver and said second demultiplexer to said continuous miner, providing as said second system, a fiber optic remote control system including a fiber optic cable remotely connecting said second transmitter with said second receiver, and transmitting light impulses from said second transmitter through said fiber optic cable to said second receiver.
Claim 8
Dependent Claim
216 words
A continuous minor comprising, a mobile frame assembly having a front end portion and a rear end portion, a material dislodging means attached to said front end portion of said mobile frame assembly, a conveying means attached to said mobile frame assembly for receiving material from said dislodging means and to convey said material rearwardly of said continuous miner, a propulsion means attached to said mobile frame assembly for propelling said continuous miner, a remote control means for activating functions on said continuous miner at a distance from said continuous miner, said remote control means having a first system and a second system for the remote control of said continuous miner, said first system having at least one switch, a first multiplexer, and a first transmitter in an operator station, said first system having a first receiver, a first demultiplexer and a first interface on said continuous miner, a second system having a second multiplexer and a second transmitter being in said operator station, said second system having a second receiver and a second demultiplexer on said continuous miner, and said second demultiplexer interconnected with said first interface on said continuous miner to receive a signal from said second system to initiate operation of said continuous miner in the event of failure of said first system.
Claim 9
Dependent Claim
