Abstract (en)
[origin: WO9111356A1] A track circuit system combined with an automatic control system for rail-mounted vehicles, in which the transmission of information to and the detection of rail-mounted vehicles in the system take place by the exchange of digital messages in the form of telegrams. The telegrams have contents with safety information with, above all, information about track cirucit identity but may also have general contents. Separate electronic units (E1, E2) generate two telegrams with the same information contents. These telegrams are compared prior to transmission to a track circuit (2), in which a receiver (B) picks up the telegram. Transmitted and received telegrams are compared for achieving fail-safety. Level indication of the received signal gives information as to whether the track cirucit is occupied. An output signal (4) from the system is used as a fail-safe signal for feeding to a traffic control system.
