<p>PURPOSE:To surely transmit a manipulated variable to a carrier car from one location, by remote-controlling the carrier can with signals from the 1st transmitting means provided at an elevated spot such as tower, etc. CONSTITUTION:At the upper section of a tower various controllers for remote- controlling a power shovel 1 which works as a carrier car are provided. An output means is composed of the 1st and 2nd reflecting mirrors 2a and 2b and 1st and 2nd driving devices 3a and 3b. In addition, a laser emitting device 4 which emits a laser beam for transmitting the manipulated variable of the power shovel 1 is provided and the laser beam is inputted to a light receiving device 5 which works as the 1st receiving means provided at the upper section of the power shovel 1 after the beam is reflected by the 2nd and 1st reflecting mirrors 2b and 2a. The laser emitting device 4 emits the laser beam upon receiving the signal of a laser communication device 6. The laser communication device 6 is operated by means of the control signal of a controller 7.</p> |
