The invention Synchronised relates to a control method of the RTV system, it is an object of efficient operation and conflict and collision accident through the mutual cooperation in synchronized RTV systems running by installing the two RTV on the same rail by the relative speed and the distance detecting device to provide a control method for a system using the synchronized RTV to prevent the efficiency, and a relative speed to improve the safety and the distance detection device of the apparatus.
To this end, a method of synchronizing RTV system using the relative speed and the distance detecting apparatus according to the present invention, the distance to the displacement sensor is operating provided in each of the RTV to travel over the same rail to measure the distance of the RTV each other in real-time and the detection step; After calculating the relative velocity in the velocity distance control board on the basis of a detection value from the distance detecting step, calculating the deceleration distance to RTV corresponds to the movement distance of the stop from the deceleration starting time necessary for the operation stop depending on the speed deceleration and distance calculation steps of; Deceleration signal transmission comprising the steps of: comparing the deceleration distance and the current distance calculated in the distance calculation step speed reduction transmitting a deceleration signal corresponding side main control board and; Mutual comparison its speed and the deceleration signal from the main control board receiving the deceleration signal by determining whether the deceleration determining whether deceleration of the RTV; comprises a.
