摘要

A system to protect the position determination of guided vehicles, automatically controlled, that they exchange, through the transmission and reception equipment located on board them and through the transmission and reception equipment associated with short consecutive sections of track, telegrams data with fixed control stations associated with individual track areas, and determine their respective position with the help of markings arranged at regular intervals along the track, performing position determination by means of a marking counter and a meter exact distance of non-contact or evaluation of the revolutions of the wheel on board each vehicle, the vehicle being able to detect the past marks only within a reception window located at a predetermined distance from the preceding mark and adjusted by the exact distance, and referring, the vehicle to the center of this window as a mark a limited number of successive times as a substitute in the event that no marks were detected within this window, characterized in that the short track sections (L10, L11) adjacent to the edges of the track area (BG) are approximately of a length such as half of the average spacing (LA) of the markings (M), because the following track sections (Figure 2, L9, L12) have a maximum length of n-2 marking spacings (LA), where the number n is the number maximum mark spacings that a vehicle can go through without detecting a mark, and because vehicles carry additional devices to measure the distance traveled without receiving information in the event that data transmission fails, and devices that consider an edge of track area (BG) communicated to vehicles in the manner known by an identification in the data telegrams to be corrected only if the distance traveled from the last possible mark and determined by the gauge di Exact stance is less than the mark spacing minus the length of the receive window (F), and the distance traveled without receiving information is less than the mark spacing.
