FIELD: physics.
SUBSTANCE: invention relates to automated process control systems, particularly ground tests of space rocket equipment. The device for switching channels of a triplex control system has in each standby control system channel a unit for analysing information exchange, connected to neighbouring units by inputs/outputs and which forms therein and in AND circuits and inverters which form an automatic logic machine a malfunction symptom of one of them, which is detected during analysis of real-time exchanged information. Output signals of the automatic machine, which realises a truth diagram, in accordance with which peripheral device control buses are switched by driver buses, are connected to the right of the faulty channel of the control signal. In an operating state of the system, said buses are connected to input/output interfaces of like channels.
EFFECT: high reliability of a triplex control system.
