Digital control system

The invention provides a digital control system, relates to the technical field of communication, and solves technical problems of enhancement of communication capacity and communication reliability. The system comprises a back board, and multiple generable logic cards and multiple signal backward-transmission modules which are interconnected with the backboard. All the general logic cards are divided into multiple logic card sequences, wherein one of the logic card sequences is an S sequence, and other logic card sequences are T sequences. In the T sequences, each general logic card is interconnected with all the general logic cards in the same sequence in a point-to-point communication mode and interconnected with the general logic cards of the corresponding positions in other T sequences in the point-to-point communication mode. In the S sequence, all the general logic cards are interconnected in the point-to-point communication mode, and each general logic card is interconnected with the general logic cards of the corresponding positions in all the T sequences in the point-to-point communication mode. The system is great in communication capacity and communication reliability.
