The invention relates to a multi-machine alarm real-time synchronization method for a marine integrated navigation system. The method comprises the following steps: 1, creating an alarm object; 2, carrying out local storage and notification on alarm data in real time; 3, alarm checking: if alarm processing operation exists and an alarm state is changed, executing a step 4; otherwise, executing the step 3; 4, issuing the updated alarm data to a main control device, and synchronously forwarding the updated alarm data to all devices of the integrated navigation system by the main control device; 5, the source credibility of the received alarm data is checked, if the source equipment of the alarm data is offline, the alarm is ignored, and the step 3 is executed; if the source equipment of the alarm data is online but the alarm data has conflicts, executing the step 4; and if the source equipment of the alarm data is online and the alarm data has no conflict, executing the step 2. According to the method, the final consistency of the alarm data can be effectively guaranteed, the transmission efficiency is high, the real-time performance is good, and the method has good robustness to interference conditions.

    本发明涉及一种船用综合导航系统多机间报警实时同步方法,包括:1、创建报警对象;2、对报警数据实时进行本地存储和通知;3、报警检查,存在报警处置操作并且发生了报警状态变化,则执行步骤4;否则执行步骤3;4、将更新后的报警数据发布到主控设备,主控设备同步转发更新后的报警数据至综合导航系统的所有设备;5、检查所接收到的报警数据的来源可信性,报警数据的来源设备已离线则忽略该报警,执行步骤3;若报警数据的来源设备在线但报警数据存在冲突,执行步骤4;报警数据的来源设备在线且报警数据不存在冲突,执行步骤2。通过本发明的方法可有效保证报警数据的最终一致性,传输效率高、实时性能好,对干扰情况具有较好的健壮性。
