SIGNAL DETECTING DEVICE FOR SELF-PROPELLING CONVEYOR TRUCK

摘要

An object of the present invention is to provide a signal detection device for detecting a signal from a traveling path of a carrier vehicle frequently.;The signal detection device 30 is frequently mounted along a traveling path of a transport vehicle, and magnetic sheets 51 and 52 magnetized with an S pole on an N-pole on the other side of the front and back surfaces, and a magnetic sheet. The magnetic pole detectors 61 and 62 are provided in the conveyance vehicle frequently so as to face each column of.;When the combination of the magnetic sheet train and the magnetic pole detector is two sets, there are eight magnetic pole combinations of the magnetic poles 51 and 52 of the N pole and the S pole. It can be detected as.
