Title:
OPERATION CONTROLLER OF ELECTROMAGNETIC INDUCTION TYPE UNMANNED CAR
Document Type and Number:
Japanese Patent JPS59231613
Kind Code:
A
Abstract:
PURPOSE:To decide on the destination of an unmanned car according to the combination of a mark for switching resonance frequencies of a sensor and the frequency of a tow bus wire by providing the mark for switching resonance frequencies of the sensor on detecting the arrival of the unmanned car to each connection part of each tow bus wire of the run line of the unmanned car. CONSTITUTION:Plural tow bus wires 1A-1C having different frequencies f1-f3 are arranged in combination to constitute the run line, and the unmanned car A is run along this run line. Steering and running wheels 3 are arranged at both breadthwise positions of the center part of the car body frame 2 of this unmanned car A, and driven wheels which are rotatable and freely directional are arranged both breadthwise positions of both front and rear side parts of the frame 2. Further, a follow-up sensor 5, mark sensor 9 which detects marks for magnetic absolute address indication provided to connection parts of the wires 1A-1C, receiver 10, and transmitter 11 are provided. Then, the arrival of the unmanned car A is detected and resonance frequencies of the sensor 9 are switched once the sensor detects a mark, thereby determining the destination according to the combination of the mark and the frequency of wires 1A-1C.
