Abstract (en)
[origin: EP0668203A1] An axle counter compares a number of pulses generated by the passage of axles with a preset threshold. The pulses are generated electromagnetically. If the threshold is exceeded, a pulse denoting the count is sent to a "device that announces that the rails are clear". The store for the threshold can be overwritten. By using a keyboard or a remote control device, an update command can be given to overwrite the store with the actual measured axle count, or a statistically calculated mean value. Thus the necessary periodic mechanical adjustment of the electromagnetic transmitter on the rails is avoided.
