FIELD: control systems.
SUBSTANCE: invention relates to control systems for responsible technological processes, in particular to railway traffic control systems for railway transport. Method and device for its implementation can be used in any control devices, regardless of their purpose and application. Control devices can be built on the basis of computer hardware, microprocessors, digital or analog elements.
EFFECT: invention provides detection of the constant states of the device of each of the duplicating channels by checking the dynamic nature of the control signals arriving at the comparison device, due to which the safety of the device operation is increased, the structure of its construction is simplified.
