摘要： An operation control system for automated guided vehicles conveying articles along an unmanned conveying system. This operational control system comprises a first travel path loop and a second travel path loop along which a first group and a second group of the automated guided vehicles are automatically travelled. A common travel path is provided along which the automated guided vehicles of both the first and the second group are travelled, to enable a transfer of articles between the groups of automated guided vehicles. Also a correlating unit for correlating one automated guided vehicle of the first group with another automated guided vehicle of the second group, and a transfer control unit for controlling the transfer of the articles between the automated guided vehicles are provided. The transfer control unit permits only a transfer of articles between automated guided vehicles correlated with each other by the correlating unit.

摘要： A travel control device for an unmanned vehicle automatically travelling along a predetermined travel path. The travel control device comprises non-contact type and contact type obstacle sensors for detecting an obstacle in front of the unmanned vehicle, and the unmanned vehicle is stopped when an obstacle is detected. A working area is predetermined along the travel path, and entrance and exit marks are provided to indicate the working area. When the unmanned vehicle enters the working area, a detection of signals output by the non-contact type obstacle sensor is disabled, to avoid unnecessary stops in the specific area and maintain a smooth travel of the unmanned vehicle. Further, a time counter is provided for counting a time from when the unmanned vehicle is stopped to a time when the unmanned vehicle is restarted, and when the unmanned vehicle is restarted, the unmanned vehicle is caused to travel at a speed higher than a previous speed at which it was travelling before being stopped, to recover a delay time incurred by the stop.
摘要翻译：一种用于无人驾驶车辆的行驶控制装置，其自动地沿着预定行驶路径行进。行驶控制装置包括用于检测无人驾驶车辆前方的障碍物的非接触型和接触式障碍传感器，并且当检测到障碍物时，无人车停止。工作区域沿着行进路径被预先确定，并且提供出入口标记以指示工作区域。当无人驾驶车辆进入工作区域时，对非接触型障碍物传感器输出的信号的检测被禁用，以避免在特定区域中不必要的停止并保持无人驾驶车辆的平稳行驶。此外，提供了一个时间计数器，用于计数从无人驾驶车辆停止到无人驾驶车辆重新启动时间的时间，并且当无人驾驶车辆重新启动时，使无人驾驶车辆以比先前在停车前行驶的速度，以恢复停车所产生的延迟时间。
