Abstract

Improvements in circuits for continuous testing of information processes consisting of a circuit for continuous functional testing of information processing and data telegram output, particularly in computer-controlled railway signaling systems, in which equal data processing systems are used and in which the information is delivered in the form of a data telegram made up of an information part and a test part, characterized by the use of three equal computers (R1, R2, R3) that have the following characteristics: - each computer (R1, R2, R3) has at least the same number of outputs (R1/al to an, R2/al to an, R3/al to an) that transmission channels (K1 to Kn) exist; - the data telegrams corresponding to the individual transmission channels (K1 to Kn) are delivered in parallel through the corresponding outputs of the computers, the individual telegram parts (bits) being applied in series to the outputs; - the data telegrams are identical at the outputs (e.g. R1/al, R2/al, R3/al) corresponding to the three computers (R1, R2, R3), - and the outputs (eg R1/al, R2/al, P-3 /) of the computers are connected to a supervision and output device (UAV), which, with majority decision, discovers a defective computer (eg R3), being possible the connection, selectively and depending on a certain sequence, of the outputs of in each case only two computers (eg R1 and R2) for the delivery of the data telegrams to the transmission channels, by by means of a clock pulse generator (T) commonly associated with the three computers (R1, R2 R3) and the monitoring and output device (UAV).
