Rail guided vehicle system

摘要

In a rail guided vehicle system, unnecessary slowing down and stopping of a vehicle passing through a divergence point and a merge point is avoided. The rail guided vehicle system comprises a rail 100 including a guidepath wire 600 in a predetermined area including the divergence point and the merge point, and a plurality of vehicles 200 that travel while being supported and guided by the rail. Each of the plurality of vehicles 200 includes a generating unit 910, 920 configured to generate each of a plurality of signals each having different frequencies from the others, a transmitting unit 810, 820 configured to send each of the plurality of signals generated by the generating unit to the guidepath wire, a receiving unit 710, 720 configured to receive each of the plurality of signals transmitted via the guidepath wire, a determining unit 955 configured to determine, based on the kind of the signal received by the receiving unit, whether the vehicle is slowed down, stopped, or kept travelling, and a controlling unit 960 configured to control the vehicle in accordance with a result of a determination determined by the determining unit.

1. A rail guided vehicle system comprising a rail having a guidepath wire in a predetermined area including a divergence point and a merge point and a plurality of vehicles that travel while being supported and guided by the rail, each of the vehicles comprising:
a generating unit configured to generate a plurality of signals, each of the plurality of signals having different frequencies from the others; a transmitting unit configured to transmit each of the plurality of signals generated by the generating unit to the guidepath wire; a receiving unit configured to receive each of the plurality of signals transmitted via the guidepath wire; a determining unit configured to determine, based on a frequency of the signal received by the receiving unit, whether the vehicle is to be slowed down, or stopped, or kept travelling; and a controlling unit configured to control the vehicle in accordance with a result of a determination determined by the determining unit, wherein a signal having an inherent and different frequency is allocated to each divergence point and merge point, and when the vehicle passes through a particular divergence point or merge point, the generating unit is configured to generate the signal having the frequency that is inherent to that particular divergence point or merge point.
