The invention provides a communication node-oriented double-computer automatic switching method for a computer interlocking system, the interlocking system comprises an interlocking upper host, an interlocking upper standby, an interlocking host, an interlocking standby and a plurality of trackside devices, and the interlocking system is configured with interlocking logic software. The method comprises the following steps: H1, formulating corresponding communication state parameters for all communication interfaces of the interlocking system; h2, the interlocking system continuously sends test data to each interface for communication fault test, and generates a corresponding communication state parameter value for each interface based on a test result; the interlocking logic software judges whether the corresponding interface has a fault or not based on the communication state parameter value; and H3, based on the fault priority, triggering the interlocking host machine and the interlocking standby machine to switch, and during switching, satisfying the following conditions: education learning between the interlocking host machine and the interlocking standby machine is synchronous, and no cross fault exists between the interlocking host machine and the interlocking standby machine. According to the invention, the dual-computer switching is triggered based on the state of the communication node, and the availability of the interlocking system is ensured.

    本发明提供一种面向通信节点的计算机联锁系统双机自动切换的方法,联锁系统包含:联锁上位主机、联锁上位备机、联锁主机、联锁备机及多个轨旁设备,联锁系统配置有联锁逻辑软件,所述方法包含步骤:H1、为联锁系统的所有通信接口制定对应的通信状态参数;H2、联锁系统持续向各接口发送测试数据进行通信故障测试,并基于测试结果为各接口生成对应的通信状态参数值;联锁逻辑软件基于通信状态参数值判断对应的接口是否故障;H3、基于故障优先级触发联锁主机、联锁备机进行切换,且切换时满足:联锁主机与联锁备机之间的教育学习同步,以及联锁主备机之间不存在交叉故障。本发明基于通信节点的状态触发双机切换,保证联锁系统的可用性。
