The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the process flow diagram of the alarm inhibiting method of nuclear plant digital alarming system of the present invention;
Embodiment
As described in Figure 1, the alarm inhibiting method of described nuclear plant digital alarming system can divide three steps to carry out: 1) alerting signal that produces in described warning system is carried out the function validation; 2) when the alerting signal of confirming in the step 1) is invalid, report to the police at the ground floor of described warning system and to forbid handling, otherwise alerting signal enters the second layer of described warning system; 3) to step 2) in enter the second layer of described warning system alerting signal carry out validation, when the alerting signal of confirming is invalid, this alerting signal is reported to the police suppresses to handle.
Wherein, the warning described step 2) is forbidden being treated to makes described alerting signal forbid that in the ground floor of described warning system this alerting signal triggers warning.Warning is forbidden handling on the ground floor in described warning system and is realized, when a warning was under an embargo, this pairing alerting signal of reporting to the police can not be sent in the second layer of described warning system and go.Reporting to the police to suppress to be treated in described step 3) makes the alerting signal that suppresses to handle of need reporting to the police enter being suppressed in the warning tabulation of described warning system, do not trigger simultaneously corresponding warning indicator, otherwise, entering in the tabulation of reporting to the police and trigger corresponding warning indicator.
Suppress to handle and to be elaborated by following several embodiment reporting to the police.
Embodiment 1
Report to the police to suppress handling can be that operating condition is reported to the police and suppressed to handle, and pre-defined 19 kinds of power station operating conditions add " undefined operating condition ", has 20 kinds of operating conditions and is used for reporting to the police and suppresses.These 20 kinds of operating conditions can be divided into 3 classes: nominal situation, unusual service condition, undefined operating mode.Wherein unusual service condition refers to that removal of load promptly is with station service, jumping machine, is jumped heap, peace is annotated these four kinds of operating modes.
Warning system can be calculated current unit operation operating mode in real time automatically according to current unit operation parameter and computational logic, can be referred to as design condition, operator also can manually select the residing operating mode of current unit simultaneously, can be referred to as to select operating mode, but except the unusual service condition.The operating mode that the design condition of warning system and operator manually select can be the same or different, effective alerting signal just can not be suppressed under the only current design condition (selecting operating mode) when both are identical, and other invalid alerting signal all can be reported to the police to be suppressed to handle; When both design conditions or select under the operating mode effectively alerting signal can not be reported to the police and suppress to handle simultaneously not.When the design condition of warning system is a unusual service condition or during for undefined operating mode, warning system can be automatically selecting operating mode be set at design condition, operator can not select other operating mode.The All Alerts signal is all effective under undefined operating mode, no longer exists the operating condition warning and suppresses to handle (but the warning of other class is forbidden handling and/or the inhibition of reporting to the police is handled still effective).When warning system can't calculate a certain definite operating mode, then warning system was set at design condition " undefined operating condition "; When the operating mode that goes out when system-computed is invalid or trystate (this operating mode was invalid or trystate when the one or more signals that are used to calculate this operating mode were invalid or trystate), system also handles by " undefined operating mode ".
Must be defined under 19 kinds of operating conditions alerting signal to each warning is effectively (can not be reported to the police and suppress to handle) still invalid (the inhibition processing of being reported to the police).When alerting signal occurs, if this alerting signal is at the design condition of warning system) or select under the operating mode effectively, then this alerting signal will appear in " tabulation of reporting to the police ", and trigger corresponding warning indicator; If all invalid under design condition and selection operating mode, then this warning appears in " being suppressed the tabulation of reporting to the police ", does not trigger corresponding warning indicator; When design condition was " undefined operating mode ", reporting to the police all appeared in " tabulation of reporting to the police ", triggers corresponding warning indicator simultaneously.
Embodiment 2
Alerting signal suppresses to handle and can be handled by other signal suppressing, and an alerting signal can be suppressed by other switching value signal, thereby should provide the inhibition signal tabulation of this alerting signal to each alerting signal.The circulation that should avoid reporting to the police when doing warning inhibition design suppresses, and as A warning inhibition B warning, B reports to the police and suppresses the C warning, and C warning inhibition A reports to the police.According to suppressing signal and be suppressed relation between the signal, reporting to the police can be divided three classes by other signal suppressing: many Threshold Alerts suppress to handle, cause and effect is reported to the police suppresses to handle, integrated alarm suppresses to handle.
It is to make two limit value alerting signals that are associated form the relation of inhibition that described many Threshold Alerts suppress to handle, for example when low alerting signal takes place, low alerting signal can be suppressed processing, promptly low alerting signal can be transferred in " being suppressed the tabulation of reporting to the police " from " tabulation of reporting to the police ", and low simultaneously alerting signal appears in " tabulation of reporting to the police "; Low alerting signal can be got back to from " being suppressed the tabulation of reporting to the police " again in " tabulation of reporting to the police " automatically when low alerting signal disappears, and low alerting signal and low alerting signal can not appear in " tabulation of reporting to the police " simultaneously.
Described cause and effect is reported to the police, and to suppress to handle be for to prevent the warning of avalanche type, and described cause and effect is reported to the police and suppressed to handle the following three kinds of situations that comprise at least: first kind of situation is that power supply forfeiture alerting signal must suppress that power supply thus disappears and other relevant alerting signal of producing; Second kind of situation is that pressurized air forfeiture alerting signal must suppress pressurized air forfeiture thus and other relevant alerting signal of generation; The third situation is that the loss of heat sink alerting signal must suppress loss of heat sink thus and other relevant alerting signal of producing.
Described integrated alarm suppresses processing and comprises that total warning suppresses to handle, described total alerting signal is meant total alerting signal that a plurality of faults just produce when occurring simultaneously, and all have independent branch alerting signal corresponding with it to each fault, only when taking place simultaneously, these faults just produce this total alerting signal.For this total alerting signal, it should suppress to constitute each minute alerting signal of this total alerting signal.
Embodiment 3
The inhibition processing of reporting to the police can be that equipment isolation warning suppresses processing, and described equipment isolation warning inhibition is handled exactly when a process equipment is isolated, and the alerting signal that this process equipment produced will be by warning inhibition processing.
It can also be that other multiple warning suppresses processing mode that certain described warning suppresses to handle, suppress to handle as reporting to the police according to the residing state of conventional island to the conventional island system, for this reason definable three conventional island operating modes: the VVP valve closes and also keeps vacuum; The VVP valve closes and destroys vacuum; CEX and APA pump are out of service.It can also be the method for operation according to particular rack; alerting signal to this system on the unit of not responsible this system suppresses to handle; so long as within the disclosed step of the alarm inhibiting method of nuclear plant digital alarming system of the present invention, all within protection scope of the present invention.
