Wherein, the first-level alarm can be an accident alarm and is the highest-level alarm. For example, when the protection system triggers an emergency shutdown or a dedicated action, the alarm system generates a primary alarm. The secondary alarm can be a pre-alarm before the protection system triggers emergency shutdown or special action. Such as an alarm that is issued when the protection monitoring variable reaches or exceeds the secondary alarm set point. The conventional island secondary alarm is generated by monitoring a conventional island process parameter or equipment state signal. The third-level alarm can be an alarm sent out when a system abnormality or equipment failure occurs in the nuclear power station.

Or, in response to the processing result being confirmed and any one of the operation data still has an abnormality, controlling the flashing frequency to be the second frequency.

Or, in response to the processing result being that the abnormality of any one of the operation data disappears, controlling the flicker frequency to be the third frequency;

the first frequency is greater than the second frequency, and the second frequency is greater than the third frequency.

For example, the first frequency may be 2 hertz (Hz), the second frequency may be 0Hz, and the third frequency may be 0.5Hz. The present disclosure is not limited thereto.

In the embodiment of the disclosure, after the alarm level, the abnormal position and the abnormal reason corresponding to any operation data are determined, the corresponding alarm light character plate and the display color in the alarm display screen are determined according to the abnormal position, the alarm level and the abnormal reason, so as to control the color display of the alarm light character plate, and further, the flickering frequency of the alarm light character plate can be controlled according to the processing result of the abnormal event. Therefore, the alarm can be efficiently and accurately given to the accident of the nuclear power station to remind workers to process the accident of the nuclear power station in time, the operation safety of the nuclear power station is ensured, and the workers are informed of the processing result of the abnormal event through the flickering frequency of the alarm light-character plate.
