  • Patent number: 4787581
    Abstract: 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.

  • Patent number: 4023753
    Abstract: A control system is proposed which is capable of controlling driverless vehicles running on a fixed guideway according to schedule or demand. An input device is disposed at each station along the guideway to enable each passenger to enter his destination. A command and control center is in communication with the vehicles on the guideway and all the input devices. The center receives from each of the input devices simultaneously destination information and the identity of that one of the input devices providing the destination information to provide start information. A memory arrangement in the center contains control information for standard and diversion routes for all possible start-destination relationships. A computer arrangement in the center determines from all input information from the input devices whether the transport system should operate in a demand or scheduled mode at that moment in view of given operating criteria.
