A DEVICE FOR THE DETECTION OF BOUNDARY BETWEEN FREIGHT CARS BY AXLE DETECTORS

While counting the axles in a train is simple, Japanese National Railways has found that determining the number of cars is complicated. Infrared sensors may be interrupted by ladings over two cars or by passenger trains which have no gaps between cars. This device was developed to determine the boundary between freight cars by differentiating the patterns of distance between axles of each car, utilizing only wheel detectors. As a result of determining the patterns of wheels on cars and locomotives, signals from four to six wheel sensors processed by a microcomputer were found effective in counting cars moving at speeds up to 29 km/h.
