Extend the function of Full scope simulator system, play the function of Full scope simulator system more fully hereinafter,
Avoid the wasting of resources.
It addition, the nuclear power station that the present invention provides is reported to the police, emulation and alarm diagnosis system can be in built numerals
On the basis of changing nuclear power station network framework, unit DCS system and Full scope simulator system are simply changed
Make the corresponding data analysis station of increase, warning storage server, unidirectional bridge, alarm diagnosis analysis station, or
Person increase in the construction of new nuclear power station corresponding data analysis station, warning storage server, unidirectional bridge,
Alarm diagnosis analysis station, to realize effectively utilizing the real time data in nuclear power station unit DCS system and gamut
Simulator system carries out the emulation function with warning reason diagnostic analysis of reporting to the police, for nuclear power station debugging and operation rank
Section warning reason analysis and alarm signal process to provide and instruct.
Alternatively, data analysis station 2 specifically for judging that whether alarm signal is the alarm signal of predetermined level,
If alarm signal is the alarm signal of predetermined level, it is determined that alarm signal is alarm signal to be emulated.
In actual application, alarm signal can be divided into multiple grade, the only alarm signal of predetermined level
Just may be considered alarm signal to be emulated.Wherein, this predetermined level can be determined by operator, this
This is not limited by bright embodiment.
Such as, the alarm signal produced in unit DCS system 1 is divided into according to required operator's response
Multiple grades: one-level alarm signal needs operator to determine subsequent treatment measure according to the scene situation of patrolling and examining；Two grades
Alarm signal needs operator to take treatment measures according to experience or operating standard；Three grades of alarm signals without
Operator manually intervenes, and system automatic interlock can be reported to the police and will comparatively fast disappear.Therefore, this predetermined level is arranged
For firsts and seconds, then one-level alarm signal and secondary alarm signal are alarm signal to be emulated.
Alternatively, data analysis station 2 specifically for when alarm signal for wait emulate alarm signal time, according in advance
If regular, from I/O general list, inquire about the I/O signal that associate with alarm signal, and divide into and wait to emulate warning
Source signal and warning operating mode I/O signal.
This data analysis station 2 possesses retrieval and reads alarm signal to be emulated, alarm source signal to be emulated and report
The function of alert operating mode I/O signal, determines that the alarm signal of generation is when the alarm signal emulated, can basis
Preset rules, inquires about alarm source signal to be emulated and warning operating mode I/O signal, in order to follow-up carry out simulation analysis.
Wherein, this preset rules needs customization in advance, and customization step includes:
The alarm signal to be emulated that the first step, grade according to each alarm signal sort out whole nuclear power station is clear
Single.
Second step, for each alarm signal to be emulated, flow to and alarm signal to be emulated according to system capacity
Producing cause is analyzed, and uses inference theory, successively downward recursion, until recursion to energy source or another
Alarm signal to be emulated, sets up the downtree type respiratory sensation process equipment figure of this alarm signal to be emulated.Wherein,

In system 4, according to the downtree type respiratory sensation process equipment figure of this alarm signal to be emulated, will figure associate
Process equipment carries out border isolation with other equipment in analog machine phantom.Full scope simulator system 4 from
Storage server 3 of reporting to the police reads the instantaneous value of alarm source signal to be emulated, and waits to imitate to replace in phantom
The state value of true alarm source signal is simulated emulation, produces the simulation value of warning operating mode I/O signal.
In the embodiment of the present invention, alarm diagnosis analysis station 5 possesses the contrast of I/O signal data deviation, alert process
Formal style judges, failure cause and the output of processing scheme, report the function such as automatically generate.
Alternatively, alarm diagnosis analysis station 5 is specifically for according to warning operating mode I/O deviation of signal table, retrieving
There is deviation I/O signal, and judge according to alert process rule, obtain corresponding with there being deviation I/O signal
Warning reason and processing scheme, generate the report of warning simulation analysis according to warning reason and processing scheme.
Specifically, the downtree type respiratory sensation work of the alarm signal to be emulated that data analysis station 2 set up is utilized
Skill equipment drawing, alarm diagnosis analysis station 5 can retrieve be positioned at down according to warning operating mode I/O deviation of signal table
The tree-shaped respiratory sensation process equipment figure bottom have deviation alarm operating mode I/O signal, the bottom have deviation report
Alert operating mode I/O signal is the I/O signal of most upstream deviation occur, also produces alarm signal to be emulated
Initial reason.Therefore, there is deviation alarm operating mode I/O signal, according to report set in advance for the bottom
The alert rule that processes judges, obtains the warning reason corresponding with there being deviation alarm operating mode I/O signal and process side
Case, and generate the report of warning simulation analysis according to the form specified.
