REMOTE CONTROLLER FOR CONSTRUCTION MACHINE

PROBLEM TO BE SOLVED: To remotely control plural construction machines at a long distance by transmitting a multiplexed control signal through a specified low power radio and controlling the respective construction machines, according to the received control signal. SOLUTION: At a remote control room 1, plural driving control signals from the operation controllers of respective construction machines 3 are multiplexed at least into one channel. The signal multiplexed this way is transmitted by a simplified radio of 50GHz. Because of this simplified radio, the signal can be transmitted to any place separated to 1-2Km at a maximum. Then, the transmitted simplified radio is received at a telecontrol outside broadcast van 2, distributed to respective drive control signals and transmitted to the respective construction machines 3 by the specified low power radio. The respective construction machines 3 receive the specified low-power radio and are remotely controlled by the drive control signals. Thus, since a large number of construction machines 3 are simultaneously remotely controlled at a long distance, the construction using a large number of construction machines 3 is enabled, even in dangerous zones.
