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.

    本发明公开了一种板级冗余的全电子计算机联锁系统,包括联锁A系、联锁B系以及主备切换控制单元,所述联锁A系包括全电子联锁单元A系、交换单元A系、全电子执行单元A系,所述联锁B系包括全电子联锁单元B系、交换单元B系、全电子执行单元B系,所述主备切换控制单元用于控制全电子联锁单元A系和全电子联锁单元B系实现主备切换,所述全电子联锁单元A系通过交换单元A系与全电子执行单元A系以及全电子执行单元B系进行通讯,所述全电子联锁单元B系通过交换单元B系与全电子执行单元B系以及全电子执行单元A系进行通讯。本发明采用单板的冗余切换方案,某系中某块安全IO板故障时,能自动切换到另一系的对应安全IO板,在不降低系统安全性前提下,较大程度的提升系统的可用性。
