Abstract (en)
[origin: EP0530743A2] In a wheel sensor for detecting wheels of railway vehicles, preferably for counting the wheels (6) in a section of track, metal-detecting, inductive sensors (1, 3, 41, 43) are attached symmetrically to travel rails (4) and their relative levels are evaluated, as a result of which interference influences of an electrical, inductive, thermal or mechanical kind are suppressed and flanged wheels can be distinguished from metal components which give the false impression of other wheels. Train types can be determined from the patterns (Fig. 4) of the signals (51, 55) when satisfactory wheels pass by and from metallic objects. The earliest arrival of the train at positions relative to the wheel sensor is calculated from the maximal speeds assigned to the train types. <IMAGE>
