TRAFFIC CONTROL METHOD FOR UNMANNED CAR CONVEYANCE SYSTEM

摘要

PURPOSE:To improve travel and traffic control efficiency by allowing an unmanned car to send back a specific answer signal with short signal length when receiving a polling signal from a central control office during its travel. CONSTITUTION:When the unmanned car CR is made to travel, the central control office 30 checks its interference with other cars, determines the position where the unmanned car CR is stopped or reduced in speed according to the check result, and sends out a stop or speed reduction command including the stop or speed reduction position to the unmanned CR. The unmanned car CR is stopped or reduced in speed only at the commanded stop or speed reduction position and sends back the answer signal with short signal length in response to polling during the car travel. Consequently, the stop time of the vehicle becomes short and one cycle of the polling is shortened, thereby performing efficiency communication control and travel control.
