The invention provides a computer interlocking system and a communication method. The computer interlocking system comprises a first safety net switch, a second safety net switch, a first logic communication unit, a second logic communication unit, a third logic communication unit and a fourth logic communication unit, wherein the first logic communication unit is in communication connection with the third logic communication unit; the second logic communication unit is in communication connection with the fourth logic communication unit; the third logic communication unit and the first logic communication unit are standby logic communication units for each other; the second logic communication unit and the fourth logic communication unit are standby logic communication units for each other. Through communication connection between the logic communication units, real-time interaction and synchronization of port IP information between the logic communication units and drifting and sharing of the port IP are realized, so that port IP configuration of a computer interlocking system with a cross interconnection structure is simpler under the condition that physical connection is not changed; and the availability and the reliability of the system are not influenced when a single-point fault or a multi-point fault occurs.

    本发明提供一种计算机联锁系统及通信方法,包括:第一安全网交换机、第二安全网交换机、第一逻辑通信单元、第二逻辑通信单元、第三逻辑通信单元和第四逻辑通信单元;其中,第一逻辑通信单元和第三逻辑通信单元通信连接;第二逻辑通信单元和第四逻辑通信单元通信连接;第三逻辑通信单元与第一逻辑通信单元互为备用逻辑通信单元;第二逻辑通信单元与第四逻辑通信单元互为备用逻辑通信单元。本发明通过逻辑通信单元间通信连接,实现逻辑通信单元间的端口IP信息实时交互同步且端口IP漂移共享,使交叉互联结构的计算机联锁系统在物理连接不变的情况下端口IP配置更简单,在单点故障或多点故障时不影响系统的可用性和可靠性。
