结合以上对本发明的详细描述可以看出， 相对于现有技术， 本发明至少具 有以下有益技术效果： 通过将核电设备正常运行状态下的历史数据建立动态规 则库， 并将获得核电设备实时运行数据与动态规则库进行匹配判断， 解决了核 电站系统仅能通过预警阈值判断核电设备运行是否存在异常， 无法实现核电站 设备运行中实时的有效判断的问题。 由于在判断在线运行状态参数异常并非核 电设备异常的情况下， 将在线运行状态参数写入动态规则库中， 避免下一次的 错误报警， 取得很好的技术效果。 实现筒单、 直接有效地判断核电设备当前的 运行数据、 参数是否异常， 极大地提高了对核电设备监控的效率。  In combination with the above detailed description of the present invention, it can be seen that the present invention has at least the following beneficial technical effects with respect to the prior art: a dynamic rule base is established by historical data under normal operating conditions of the nuclear power equipment, and real-time operational data of the nuclear power equipment is obtained. The matching judgment with the dynamic rule base solves the problem that the nuclear power plant system can only judge whether the nuclear power equipment operates abnormally through the early warning threshold, and cannot realize the real-time effective judgment in the operation of the nuclear power plant equipment. In the case that it is judged that the abnormality of the online running state parameter is not abnormal of the nuclear power device, the online running state parameter is written into the dynamic rule base to avoid the next false alarm, and a good technical effect is obtained. The realization of the single, direct and effective judgment of the current operating data of the nuclear power equipment, parameters are abnormal, greatly improving the efficiency of monitoring nuclear power equipment.
根据上述原理， 本发明还可以对上述实施方式进行适当的变更和修改。 因 此， 本发明并不局限于上面揭示和描述的具体实施方式， 对本发明的一些修改 和变更也应当落入本发明的权利要求的保护范围内。 此外， 尽管本说明书中使 用了一些特定的术语， 但这些术语只是为了方便说明， 并不对本发明构成任何 限制。  According to the above principle, the present invention can also be appropriately modified and modified as described above. Therefore, the present invention is not limited to the specific embodiments disclosed and described herein, and modifications and variations of the present invention are intended to fall within the scope of the appended claims. In addition, although some specific terms are used in the specification, these terms are merely for convenience of description and do not impose any limitation on the invention.
