Abstract: In a teaching method, a vehicle, which travels along a traveling rail, is allowed to arrive at a reference loading/unloading position adjacent to a reference seating surface having a reference QR code displayed thereon. A first image corresponding to the reference seating surface is acquired at the reference loading/unloading position. The vehicle, which further travels along the traveling rail, is allowed to arrive at a target loading/unloading position adjacent to the target seating surface having a target QR code displayed thereon. A second image corresponding to the target seating surface is acquired at the target loading/unloading position. The first image and the second image are compared with each other to acquire n X-axial directional teaching relative value and a Y-axis directional teaching relative value.

Abstract: Provided is a carriage system control method and carriage system control apparatus capable of preventing a transportation delay, the carriage system control method including (a) performing upper-level communication to receive bidirectional information by using wireless communication in a normal state from a track controller or a carriage moving along rails of a track and supplied with power through the track or power supply cables, (b) determining whether an abnormal state in which the upper-level communication is disabled has occurred, (c) determining whether current is being applied to the track or the power supply cables, when it is determined that the abnormal state has occurred, and (d) maintaining operation of the carriage or the track controller without closing a corresponding lane to prevent a transportation delay, when it is determined that current is being applied to the track or the power supply cables.
