Abstract

A control method for continuously checking the output results of information processing and data telegram output, for data processing systems, and in particular for railway signaling systems controlled by process (computer), using three computers that operate in parallel and protecting the data telegrams sent by means of certain codes. Characterized in that each computer (R1, R2, R3) makes its own data telegram (T1, T2, T3). One of the computers, for example, R1, which works as an output computer, compares the data telegram (T1) made by itself, with the data telegram (T2) made by another computer, for example, R2, which functions as a comparator computer, which is transmitted to a special output field (area) (AF) of the output computer. In case of coincidence, said data telegram (T2) is transmitted to an output register (reg-a) outside the computers. This data telegram (T2), written in the register (re-a), is reread by the computer, for example R3, which functions as a check/re-read computer and is compared with the data telegram (T3) made by the same. In case of coincidence, the data telegram (T2) stored in the output register (reg-a) is carried out. (Machine-translation by Google Translate, not legally binding)
