Understandably, in an embodiment, the preset number of the alarm cards is 78, and the 78 alarm cards are all associated with the trip abnormity of the nuclear power generating unit; the implementation requirement is the reflection of the alarm content of the alarm card, for example, the alarm content is a condenser vacuum low alarm, and the implementation requirement reflected by the alarm card is also the condenser vacuum low alarm; the purpose of logic configuration is to present a logic algorithm, that is, to express a judgment flow and a result required for reaching the alarm content, the purpose of logic compilation is to add a judgment condition (alarm value) to a logic configuration result for operation compilation, and to judge whether the judgment condition has a condition for reasonable execution after the judgment condition is added to the judgment flow and the result, and to generate a logic diagram with an execution logic after the condition for reasonable execution has been met. According to the embodiment, the abnormality detection sensor can be used for judging whether the nuclear power unit is abnormal or not according to the logic execution sequence.

Understandably, the preset function simulator can perform data simulation on alarm cards (more than 2000 alarm cards) associated with all nuclear power units, or can independently select part of alarm cards associated with the nuclear power units to perform data simulation, and the purpose of the data simulation is mainly to determine whether the content presented by the alarm cards has data and format errors, so that the embodiment can avoid generating wrong data and format in the process of really using the alarm cards, and does not delay the progress of locating unit fault points.
Further, the calling out a curve link according to the alarm instruction includes:
and acquiring estimated fault reasons associated with the alarm instruction, and calling at least one curve link according to the number of the estimated fault reasons.
Understandably, the alarm content associated with the alarm card at the alarm instruction includes, but is not limited to, one or more of the following: the water level of the steam generator is less than-5% of a preset program setting value, and the preset fault reason is that any two pressure meters in a plurality of (more than two) steam turbine steam inlet pressure meters have faults; any two water level gauges of the plurality (two or more) of steam generator water level gauges fail; adjusting the fault; failure of the feed pump; the power or the rotating speed of the steam turbine generator unit is changed rapidly; loss of regulated air supply or loss of 48V dc power supply; and the steam turbine steam inlet pressure gauge has a fault, wherein the alarm instruction can call three curve links.

and displaying the fault consequence corresponding to the real fault reason for the operator in the display equipment, and enabling the operator to execute the response measure corresponding to the real fault reason within a preset time threshold.
Understandably, the real fault reason is determined by analyzing a curve picture, and when the water level of the steam generator is less than-5% of a preset program setting value, the alarm content related to the alarm instruction is determined by analyzing the curve picture in the alarm card related to the alarm instruction, and the determined real fault reason can be one or more of estimated fault reasons.
