摘要
A train detection system is disclosed which works on the axle-counting principle and in which preprocessing units each containing a two-microprocessor system are associated with the individual detection points. Along the track, a major number of preprocessing units are connected with a central evaluation unit which interrogates the preprocessing units for stored counts on a cyclic basis. This interrogation is performed separately for each microprocessor of a preprocessing unit. In addition to containing counts, data telegrams transmitted to the evaluation unit include functional characters which make it possible to check the correct functioning of the detection points and preprocessing units at short intervals.
