The invention discloses a board-level redundant full-electronic computer interlocking system which comprises an interlocking system A, an interlocking system B and a main/standby switching control unit. The interlocking system A comprises a full-electronic interlocking unit system A, an exchange unit system A and a full-electronic execution unit system A. The interlocking system B comprises a full-electronic interlocking unit system B, an exchange unit system B and a full-electronic execution unit system B. The main/standby switching control unit is used for controlling the full-electronic interlocking unit system A and the full-electronic interlocking unit system B to realize main/standby switching. The full-electronic interlocking unit system A communicates with the full-electronic execution unit system A and the full-electronic execution unit system B through the exchange unit system A, and the full-electronic interlocking unit system B communicates with the full-electronic execution unit system B and the full-electronic execution unit system A through the exchange unit system B. A single board redundancy switching scheme is adopted, when a certain safety IO board in a certain system breaks down, the system can be switched to the corresponding safety IO board of the other system, and the usability of the system is improved to a large extent on the premise that the safety ofthe system is not reduced.
