Title:
TRAVELING GUIDING DEVICE FOR UNMANNED VEHICLE
Document Type and Number:
Japanese Patent JPS63111505
Kind Code:
A
Abstract:
PURPOSE:To prevent an unmanned vehicle from getting out of its traveling route by providing a conductive guide line along the traveling line and adding a transmission coil and a reception coil which detects the change of a magnetic field to the vehicle. CONSTITUTION:A conductive guide line 11 is set along a traveling route of an unmanned vehicle and a guide line sensor is added to the vehicle. This guide line sensor contains a transmission coil 20 set in parallel to the line 11 and a reception coil 21 set orthogonal to the line 11. The coil 20 is connected to an oscillator 22 and the coil 21 is connected to a shift value identifier 25 via an amplifier 23 and a phase detector 24. The output signals of the coil 21 are supplied to drivers 26 and 27 of motors 4 and 5 respectively. If the vehicle has its traveling position shift in a guidance mode, the different currents are produced at both coils 20 and 21. Then the phase and shift value of the vehicle are detected and eliminated by correction.
