    摘要: Communication between a controller and a set of automated vehicles in a manufacturing facility is improved by use of a closed-loop control system that operates on a real-time interrupt basis in which autonomous carriers report their location, sensed from reference markers along a track, the reference markers being referenced to an absolute grid in space, to a central controller or to one of a set of zone controllers that monitor the location of nearby vehicles that ordinarily use a token-passing system to avoid collisions, but which controllers can intervene to prevent one vehicle from blocking or interfering with another.

    摘要: Disclosed is an automated-guided vehicle (AGV) system comprising an AGV travelling on a facility line, having vehicle body, a driver for driving the vehicle body and a transfer device for transferring a wafer to and from a cassette; and a central control device controlling an operation of the AGV, the central control device comprising a central communicator, communicating with the AGV according to a predetermined communication protocol, the AGV comprising a radio communicator, communicating with the central communicator according to the predetermined communication protocol, and a controller activating the transfer device according to a command received by the radio communicator to transfer the wafer and controlling an operation of the driver. With this configuration, an AGV system enables communication between a central control device and an AGV according to the communication protocol, thereby loading and unloading the wafers 30 one by one.
