WIRELESS REMOTE CONTROL SYSTEM, WIRELESS MOVING TYPE WORKING MACHINE, REMOTE CONTROLLER, AND WIRELESS DEVICE EQUIPPED WITH ELECTRIC WAVE REFLECTING MECHANISM

摘要

PROBLEM TO BE SOLVED: To enhance the reliability of signal transmission systems connected to wireless devices equipped with electric wave reflecting mechanisms and to make the wireless devices compact, relating to a wireless remote control system, a wireless moving type working machine, and the wireless devices. SOLUTION: A wireless moving type working machine 1 which can be made to do work movably in a working site through wireless control by use of a first wireless device 4 and a remote controller 2 which controls the wireless moving type working machine 1 by use of a second wireless device 31 are provided. The first and second wireless devices 4, 31 are constructed as fixed wireless devices equipped with respective conical scan antennas 7, 35, and electric wave reflecting mechanisms 9, 37 having electric wave reflecting members 8, 36 whose attitudes can be adjusted to positions opposite to the conical scan antennas 7, 35 are provided. Automatic tracking control means 10, 34 which execute automatic tracking control of the wireless moving type working machine 1 by controlling the electric wave reflecting mechanisms 9, 37 are provided.
