RADIO CONTROLLER FOR WORK USE TRAVELLING WAGON

摘要

PURPOSE:To avoid crosstalk between travelling wagons by adopting a radio means for sending control information between a control section and a travelling wagon and between the travelling body and a work section respectively in terms of cordless way and selecting different kinds of aerial transmission waves in which the radio means are not interfered with each other. CONSTITUTION:A control section 6 mounted on a vehicle such as track connects to a transmitter-receiver 7 and the transmitter-receiver 7 sends and receives a radio wave to/from a transmitter-receiver 8 mounted on the travelling body 1. Moreover, one transmitter-receiver 9 is mounted on each travelling wagon 1, and the other transmitter. receiver 10 is mounted on a work part 3. Then the work drive of each travelling wagon 1 is implemented by the information exchange between the control section 6 and the travelling wagon 1, and in this case, an information exchange medium between the the control section 6 and the work section 3 is an ultrasonic wave and independently of a radio wave being the information exchange medium between the control section 6 and the travelling wagon 1. Thus, they are not interfered with each other even when the frequency is the same. Thus, crosstalk is prevented to avoid malfunction.
