The invention discloses a full-electronic computer interlocking system based on switching buttons. A full-electronic interlocking unit system A communicates with a full-electronic execution unit system A and a full-electronic execution unit system B through an exchange unit system A. A full-electronic interlocking unit system B communicates with the full-electronic execution unit system B and thefull-electronic execution unit system A through an exchange unit system B. An IO single board has a fault diagnosis function. When any IO single board in the full-electronic execution unit system A orthe full-electronic execution unit system B breaks down, the system is automatically switched to the corresponding IO single board of the other system, and the IO single board is used for controllingthe controlled equipment. A redundancy switching button is arranged on each IO single board, the main state and the standby state of the current IO single board are turned over, and if the automaticswitching result is inconsistent with the action result of the redundancy switching button, the main state and the standby state of the IO single board of each full-electronic execution unit are controlled only on the basis of the action of the redundancy switching button. According to the invention, the availability of the system is improved to a greater extent on the premise of not reducing thesecurity of the system.

    本发明公开了一种基于切换按钮的全电子计算机联锁系统,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,IO单板具有故障诊断功能,当全电子执行单元A系或全电子执行单元B系中任一IO单板故障时,系统自动切换到另一系对应IO单板,由该IO单板对被控设备进行控制,且在每块IO单板上,均设置一个冗余切换按钮,对当前IO单板的主备状态进行翻转,若自动切换结果与冗余切换按钮动作结果不一致时,全电子执行单元IO单板的主备状态控制仅以冗余切换按钮动作为准。本发明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。
