Description
Technical field
The present invention relates to rail traffic automatic fields, more particularly, to a kind of method of real-time system alarm false alarm prevention.
Background technique
There are many automated systems in field of track traffic, for realizing the monitoring and control function to field device,
Typical rail traffic automated system has ISCS(Integrated Supervisory and Control System, comprehensive
Monitoring system), PSCADA(Power Supervisory Control And Data Acquisition system electric power prison
Control system), BAS(Building Automatic System, environment and equipment monitoring system) etc., these automated systems
One of core function be monitoring field equipment state, carry out Realtime Alerts when field equipment state exception, with prompt user and
When pay close attention to warping apparatus, quick prosthetic appliance failure minimizes adverse consequences caused by equipment fault.
But field device during routine use can modulated trial signal, dither signal, quick acting involution it is (or out-of-limit
Involution) signal interference, i.e., field device can cause under the situation that is disturbed its state it is normal between exception frequently back and forth
Variation.According to the existing field equipment state abnormal alarm determination method of automated system, interference signal will lead to Department of Automation
System is frequent within the very of short duration time, falsely generates a large amount of unit exception alarm, generates wrong report.Automated system generates
A large amount of wrong report alarm, will affect user's normal use automated system, influences monitoring work of the user to field device, pole has
Actually useful unit exception alarm be may cause by wrong report alarm covering, real faulty equipment can not be supervised in real time
Control, reduces ease for use, the reliability and stability of system.
Summary of the invention
The present invention is to overcome above situation insufficient, it is desirable to provide a kind of technical solution that can solve the above problem.
A kind of method of real-time system alarm false alarm prevention, including automated system, the automation Design are temporarily delayed
Deposit area, automation Design equipment state variable, automation Design temporary buffer retention time, including following step
It is rapid:
S1, automated system obtain equipment state；
S2, automated system are recorded in equipment state in temporary buffer, when the equipment state of temporary buffer records preservation
A length of temporary buffer retention time；
S3, automated system are recorded in equipment last state in equipment state variable；
S4, after temporary buffer timing, automated system by temporary buffer value and equipment state variable value ratio
Compared with；
S5, generating device alarm.
As a further solution of the present invention: the temporary buffer retention time is 5 seconds.
As a further solution of the present invention: automation Design temporal cache zone state keeps timer, faces
When buffer state keep timer judge whether the state in temporary buffer maintains 5 seconds.
As a further solution of the present invention: if the S4 equipment state during temporary buffer retention time is not sent out
Value in temporary buffer is compared by changing, automated system after timing with the value in equipment state variable,
If value in temporary buffer and the value of equipment state variable are inconsistent, the state write device state in temporary buffer
In variable, generating device alarm.
As a further solution of the present invention: if S4 equipment state in the temporary buffer retention time does not become
Change, the value in temporary buffer is compared by automated system after timing with the value in equipment state variable, temporarily
If the value and equipment state variable in buffer area are consistent, without any processing.
As a further solution of the present invention: if S2 equipment state in the temporary buffer retention time occurs again
Field device last state is recorded in temporary buffer by variation, automated system, is restarted timing and is repeated S1 process.
Compared with prior art, the beneficial effects of the present invention are: equipment state will not generate equipment after changing immediately
Alarm, but stablize in equipment state and keep regeneration alarm after a certain period of time.Especially at the scene the modulated trial signal of equipment, tremble
In the case where dynamic signal, quick acting involution (or out-of-limit involution) signal interference, equipment alarm wrong report can be greatly reduced
Probability reduces the equipment alarm quantity of system, improves the availability and stability of system, allows users to concentrate one's energy to pay close attention to
The equipment really to break down, repairs faulty equipment in time, reduces the influence to the production and operation to greatest extent.
Additional aspect and advantage of the invention will be set forth in part in the description, and will partially become from the following description
Obviously, or practice through the invention is recognized.
Specific embodiment
Below in conjunction in the embodiment of the present invention, technical solution in the embodiment of the present invention is clearly and completely retouched
It states, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on the present invention
In embodiment, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
A kind of method of real-time system alarm false alarm prevention, including automated system, the automation Design are temporarily delayed
Deposit area, automation Design equipment state variable, automation Design temporary buffer retention time, including following step
It is rapid:
S1, automated system obtain equipment state；
S2, automated system are recorded in equipment state in temporary buffer, when the equipment state of temporary buffer records preservation
A length of temporary buffer retention time；
S3, automated system are recorded in equipment last state in equipment state variable；
S4, after temporary buffer timing, automated system by temporary buffer value and equipment state variable value ratio
Compared with；
S5, generating device alarm.
The temporary buffer retention time is 5 seconds.
Automation Design temporal cache zone state keeps timer, and temporal cache zone state keeps timer to sentence
Whether the state in disconnected temporary buffer maintains 5 seconds.
If the S4 equipment state during temporary buffer retention time does not change, automated system is in timing
After the value in temporary buffer is compared with the value in equipment state variable, the value in temporary buffer and equipment shape
If the value of state variable is inconsistent, in the state write device state variable in temporary buffer, generating device is alarmed.
If S4 equipment state in the temporary buffer retention time does not change, automated system terminates in timing
The value in temporary buffer is compared with the value in equipment state variable afterwards, the value in temporary buffer and equipment state become
If amount is consistent, without any processing.
If S2 equipment state in the temporary buffer retention time changes again, automated system sets scene
Standby last state is recorded in temporary buffer, is restarted timing and is repeated S1 process.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case where without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power
Benefit requires rather than above description limits, it is intended that all by what is fallen within the meaning and scope of the equivalent elements of the claims
Variation is included within the present invention.Any in claim should not be construed as limiting the claims involved.
