The invention relates to rail transport, in particular to a method of determining the location of a moving vehicle. Known methods of measuring distance traveled by train (see joint volume 11 Rail 11 D. Automatics, telemechanics and communication on the Railways, 2000, No. 5, application No. 19729981 Germany, IPC 6 G 01 22/00/ Mindel K.; Alcatel Alsthom. Generale d'electricite. No. 197299814; Appl. 12.07.97; Publ. 14.01.99 "Method of measurement of the distance and speed railway rolling stock). Measurement speed railway rolling stock and they traversed the path based on a system of sensors installed on Board rolling stock, and the location on the way of special tokens. The closest technical solution to the proposed method is a method of identifying barriers to the movement of rail vehicles, for example trains (see joint volume 11 Rail 11 D. Automatics, telemechanics and communication on the Railways, 2000, No. 5, application No. 19746970 Germany, IPC 6 61 L 23/00/ Uebel, H.; Alcatel. No. 197469701; Appl. 24.10.97; Publ. 29.04.99 "Method of detecting obstacles on the tracks"). On Board the vehicle mounted computer memory which contains information about the terrain on which the trail passes, and fixirovannomu points with known coordinates. The locomotive is also a special sensor for distance measurement and angle determined by using reflectors, equipped along the path. The problem to which the invention is directed, is the location of a moving vehicle, by installing a computer system (computer) and additional peripheral devices onboard the object. In computer memory contains information in the form of an ordered array of data about the terrain on which the trail passes, and fixed reference points with known coordinates. A fundamental element of the array data is information about the coordinates of the placement along the railway line clamps catenaries. A conceptual system diagram of the proposed method are presented in figure 1. Additional devices required to collect and convert the information received in the computer 4, present: the photo-sensor 1, for example a video camera, an analog-to-digital Converter video 2, pulsing element 3 for reference intervals of time synchronization of the operation of the system. The algorithm of functioning of the system running software embedded in the computer shown in figure 2 in the form of a block diagram and represents the following procedure. With the photosensor continuous the main flow enters information in the format of video sufficient resolution to distinguish between the intersection of the latch pin of the suspension and the suspension. The signal from the pulsing element analog-to-digital Converter of the signal produces fixation (capture) of the frame image photosensor. The next step of the algorithm is the digitization of the frame. The frame transmission in computers. Analysis of the pattern-matching image (mask latch). If a negative decision, the return to the beginning of the algorithm and expectation of the pulsing signal. If a positive decision comparing is the capacity value of the variable that is responsible for storing the sequence number of the current release contact suspension on this route. On the basis of the obtained number is the data sampling point of the route. The next step is the calculation of the dependency of the change of distance and speed from time to time. The final step of the algorithm is the determination of the end point of the path. If a negative decision, the return to the beginning of the algorithm and expectation of the pulsing signal. In case of positive decision the comparison terminates the algorithm. The method of determining the location of a moving rail vehicles, namely, that on Board, such as a locomotive, install computer, in memory of which enter information about the terrain on which the trail passes, and fixed reference points with known coordinates, characterized in that the locomotive additionally sets forth the t photosensor for example, a video camera, by means of which carry video clips catenaries and provide information with a resolution sufficient to distinguish between the intersection of the latch pin of the suspension and the suspension, analog-to-digital Converter of exercise video frame capture images from a video camera, digitizing a frame and transfer it to the computer, where comparing the frame with the mask of a latch with a positive result of the comparison, increasing the value of a variable that is responsible for storing the sequence number of the lock pin pendants on this route, and on the basis of the obtained non producing data sampling point of the route.
