Referring to Fig. 2, in step S301, searched from the property set of node matched multiple with multiple warning messages difference
Prestore warning message.
For example, being directed to any warning message, can come to search and any report from the property set of node in the following manner
What alert information matched prestores warning message: the component part alarmed is determined based on any warning message, from it is identified
It is searched in the property set of the corresponding node of the component part alarmed, prestores warning message with what any warning message matched.
In a preferred embodiment, alarm is prestored to guarantee to find match multiple from the property set of node
Information need to detect the content integrity of multiple warning messages of acquisition after getting multiple warning messages.Example
Such as, by taking any warning message of acquisition as an example, judge obtain any warning message in whether comprising component part title and
Alarm content, if in any warning message obtained including the title and alarm content of component part, it is determined that any report
The content of alert information is complete, if do not included in the title and/or alarm of component part in any warning message obtained
Hold, it is determined that the content of any warning message is incomplete, at this point, need to be by inputting come content (such as group of completion missing
At title of part and/or alarm content), to execute subsequent step based on complete warning message.
In step s 302, determine with matched multiple prestore the corresponding multiple component parts of warning message.
In step S303, according to multiple component parts incidence relation present in system topology figure, generation can
It can causality figure.
The incidence relation next life present in system topology figure according to multiple component parts is introduced referring to Fig. 3
The step of at possible causality figure.It should be understood that the mode of the possible causality figure of generation shown in Fig. 3 is merely illustrative, other
Method for generating possible causality figure is also feasible.
Fig. 3 show in Fig. 2 according to an exemplary embodiment of the present invention according to multiple component parts in system topology
Incidence relation present in figure generates the flow chart of the step of possible causality figure.
All warning messages are traversed in step s310 referring to Fig. 3, obtain multiple warning message combinations.Here, any
It include two warning messages in warning message combination.
In one embodiment, n warning message A of dual traversal can be passed through1,A2,…,AnMode, obtain alarm combination Ai
With Aj(1≤i, j≤n and i ≠ j).
In step S311, two alarm signals in combining in system topology figure with k-th of warning message are determined
It ceases between corresponding two component parts with the presence or absence of the side or access being connected.
Here, there is the side being connected between two component parts can refer to two component parts in system topology figure
Between be directly connected to by a directed edge.There are accesses can refer to two compositions in system topology figure between two component parts
It is connected between part by two or two or more sides.
For example, by taking above-mentioned cited embodiment as an example A alarm can be combinediWith AjCorresponding two component parts mapping
For the node collection { V on ESGb,Vc, it is searched on ESG from V using DFS (depth-first search) algorithmbTo VcSide or access.
If phase is not present between corresponding two component parts of two warning messages in combining with k-th of warning message
The side of connection or access, then follow the steps S312: so that k=k+1, and return to step S311.
It is connected if existed between corresponding two component parts of two warning messages in being combined with k-th of warning message
The side connect or access, then follow the steps S313: being associated with pass present in system topology figure according to two component parts
It is the cause and effect points relationship determined between two warning messages.
In step S314, judge whether k is equal to M.
As an example, the initial value of k can be 1, at this point, 1≤k≤M, M are the number of warning message combination, M is greater than zero
Natural number.However, the present invention is not limited thereto, the initial value for being also possible to k is M, judges whether k is equal to 1 in step S314, herein
In the case of, k=k-1 should be made in step S312 and S315 to realize circulation.
If k is not equal to M, S315 is thened follow the steps: so that k=k+1, and return to step S311.
If k is equal to M, S316 is thened follow the steps: according to all warning messages and corresponding cause and effect points relationship, generating
The possibility causality figure.
By taking above-mentioned cited embodiment as an example, if there is from VbTo VcThe side being connected or access, then store report
Warning message A in alert combinationiAnd AjAnd cause and effect points relationship between the two.It is above-mentioned having been executed to all alarms combination
After circular treatment, using the warning message stored as node, the cause and effect points relationship between warning message is side, more to establish
Possibility causality figure PCRG between a warning message.
In a preferred embodiment, possible causality figure may include node collection and side collection.
For example, each node that node is concentrated can be the warning message obtained, associated two nodes will be present by side
It is attached, indicates there is possible causality between two warning messages connected by side, and the Compass for passing through side
Show while terminal node warning message dependent on while the warning message of start node generate.
Fig. 1 is returned, in step s 40, according to determining possibility causality figure, generates the report for being directed to multiple warning messages
Alert processing sequence.
It in a preferred embodiment, can be by carrying out beta pruning processing to possible causality figure, to obtain alert process sequence.
It is introduced referring to Fig. 4 according to determining possibility causality figure and generates the alarm for multiple warning messages
The step of processing sequence.It should be understood that the mode shown in Fig. 4 for generating alert process sequence is merely illustrative, other are used for basis can
The method that energy causality figure generates alert process sequence is also feasible.
Fig. 4 shows the alert process that the generation in Fig. 1 according to an exemplary embodiment of the present invention is directed to multiple warning messages
The flow chart of the step of sequence.
Referring to Fig. 4, in step S401, judge whether possible causality figure is empty graph.
If possible causality figure is empty graph, then does not generate the alert process sequence for multiple warning messages.
If possible causality figure is not empty graph, thens follow the steps S402: search for in-degree from possible causality figure
The node for being zero.
Here, the node that in-degree is zero can refer to be directed toward oneself there is no cause and effect points relationship in possible causality figure
The node on side.
In step S403, judge whether the quantity for the node that the in-degree searched is zero is greater than 1.
If the quantity for the node that the in-degree searched is zero is greater than 1, S404 is thened follow the steps: according to history partial ordering relation
The processing priority of the corresponding warning message of the node that determination is zero with the in-degree searched, and according to determining processing priority
By be zero with the in-degree searched node corresponding warning message deposit alert process sequence in.
As an example, history partial ordering relation may include the history alarm treatment sequence between different warning messages, to be based on
History alarm treatment between different warning messages sequentially determines the processing priority of warning message.In alert process sequence
Multiple warning messages are ranked up according to the processing priority of warning message.
For example, if the corresponding warning message of a node in the node that each in-degree is zero is in history alarm treatment sequence
In disposition sequence prior to other nodes for searching, it is determined that the processing priority of the corresponding warning message of a node
Also formerly.
In addition to the above, corresponding if there is the node for being zero with the in-degree searched in history alarm treatment sequence
Each warning message alarm treatment sequence mutually first each other situation, then according to each warning message in history alert process sequence
The alarm treatment sequence frequency that formerly situation occurs, to determine the corresponding warning message of the node for being zero with the in-degree searched
Processing priority.
In addition, according to the processing of the corresponding warning message of node that the determination of history partial ordering relation is zero with the in-degree searched
The step of priority, can further include: if there is no the node for being zero with the in-degree searched is corresponding in history alarm treatment sequence
Warning message alarm treatment sequence, then according to from may search in-degree is zero in causality figure node search-order
The processing priority of the corresponding warning message of the node that determination is zero with the in-degree searched.For example, the section formerly scanned for
The processing priority of the corresponding warning message of point is also first.
Here, history alarm treatment sequence between different warning messages can expert by sewage treatment field or scene
Alarm treatment sequence between multiple warning messages that operation maintenance personnel rule of thumb provides, for example, two air blowers are shut down simultaneously
The processing priority of alarm is higher than influent COD upper limit alarm.As an example, putting into operation a period of time to system, one is had
The alert process sequence that series is generated, at this point, warning message A1Prior to A2Processed and warning message A2Prior to A1It is processed
Situation may occur simultaneously, in the case, can be according to warning message A1Prior to A2Processed and warning message A2Prior to A1Quilt
The frequency occurred in history alarm treatment sequence is handled, determines the A in current alerts processing sequence1And A2First post-processing time
Sequence.If warning message A1Prior to A2Processed number is greater than warning message A2Prior to A1Processed number, then report currently
A in alert processing sequence1Processing priority be higher than A2Processing priority.
That is, sequentially or the search-order for the node that in-degree be zero can be searched for determine using history alarm treatment
The processing priority of multiple warning messages.
If the quantity for the node that the in-degree searched is zero is not more than (that is, being less than or equal to) 1, then follow the steps
S405: by be zero with the in-degree searched node corresponding warning message deposit alert process sequence in.
Here, in cause and effect points relationship while start node warning message processing priority be higher than while terminal node
The processing priority of the warning message of point.In alert process sequence multiple warning messages according to warning message processing priority
It is ranked up, the processing priority for the warning message being first stored in alert process sequence is stored in alert process sequence after being higher than
The processing priority of warning message.
In step S406, the node that in-degree is zero and the node for being zero with in-degree are deleted from possible causality figure
Associated side, the possibility causality figure after obtaining beta pruning, and return to step S401.
In a preferred embodiment, the fault alarm method of sewage treatment plant according to an exemplary embodiment of the present invention can be also
It include: the alert process sequence that display generates.
For example, multiple warning messages can be shown according to processing priority carry out sequence in alert process sequence, with for
Operation maintenance personnel processing warning message offer assists help, this had both facilitated new operation maintenance personnel and has adapted to new working environment as early as possible, mentioned
High its ability for handling emergency problem, it helps reduce post threshold, allow other staff also can interim part-time operation maintenance personnel
Post helps sewage treatment plant to reduce cost of human resources.
In addition, the fault alarm method of sewage treatment plant according to an exemplary embodiment of the present invention can further include: display is more
The warning reason of a warning message and alarm treatment method for each warning message.
For example, can be stored in advance in the database multiple warning messages warning reason and corresponding alarm treatment method,
After getting multiple warning messages, warning reason corresponding with multiple warning messages and alarm treatment are searched for from database
Method, to be shown.
That is, shown report of the fault alarm method of exemplary embodiment of the present in most of monitoring systems
On the basis of alert record (such as alarm date, time of fire alarming, alert locations, monitored variable and alarm trigger condition), increase to report
The display of alert reason and alarm treatment method, enable operation maintenance personnel quickly know alert consitions triggering possibility warning reason and
Countermeasure.
The example of a sewage treatment plant will be passed through below, it is next using the fault alarm method of above-mentioned sewage treatment plant to introduce
Generate the process of alert process sequence.
Sewage treatment is to make sewage purification using the method for physics, chemistry and biology, can recycle, be multiplexed, to reach
To protection environment and the purpose for making full use of water resource.The basic principle is that passing through filtering, absorption, precipitating, oxidation and reduction etc.
Process realizes the removal and conversion of a variety of inorganic pollutions and organic pollutant in sewage.In order to guarantee sewage disposal process energy
It enough goes on smoothly, the process flow of multistage close association will be not only arranged in sewage treatment plant, there is provision of a variety of auxiliary systems
With auxiliary facility.Large and medium-sized sewage treatment plant's land occupation is in large scale, and on-site also wraps other than complicated process flow system
Include power supply-distribution system, blast aeration system, automatic medicament feeding system, monitoring system, heating ventilation air-conditioning system and fire protection alarm system etc..
These systems can be further divided into the smaller subsystem of range again, as process flow system can be analyzed to sewage disposal system
And sludge treating system.Due to the complexity of sewage disposal process, inside the multiple systems and same system of sewage treatment plant
The characteristics of close-coupled is all shown between multiple subsystems.
Fig. 5 shows sewage disposal system, sludge treating system and blast aeration system according to an exemplary embodiment of the present invention
The schematic diagram of system.It should be understood that Fig. 5 is with sewage disposal system, sludge treating system and the blast aeration system in sewage treatment plant
It is introduced for the equipment component that system includes, the other equipment in sewage treatment plant can also be shown using the present invention
Fault alarm method described in example property embodiment is handled, and the present invention is to this without enumerating.
Fig. 5 gives sewage disposal system, sludge treating system and blast aeration system and its pass of certain sewage treatment plant
System.As shown in figure 5, the sewage into sewage treatment plant first flows through coarse rack, the impurity of larger particles in the water that shuts off.Elevator pump
The water pump in room, which is taken out, rises sewage to certain altitude, guarantees that sewage can flow through subsequent each processing unit by gravity.Next,
Sewage further removes the impurity of smaller particle by fine fack.Sewage turns under the drive of the motor in rotation setting pot
It is dynamic, to realize girt-water separation.The effect of hydrolysis acidification pool is to retain the non-dissolved organic matter in sewage and be gradually changed into
Dissolved organic matter, it is difficult to which biodegradable macromolecular substances are converted into the small-molecule substance for being easy to degrade, to improve sewage
Biodegradability and degradation speed.Integrated oxidation ditch uses inversion A2O technique (anoxic-anaerobic-aerobic), activated sludge benefit
Biochemical reaction is carried out with the pollutant in the air and sewage entered by exposure, to realize denitrogenation dephosphorizing.The air entered by exposure is by air blast
Air blower in computer room generates, and is delivered in oxidation ditch via pipeline and valve.Air blower in air blast computer room receives power distribution station drop
The control signal of 380V industrial electro and PLC (programmable logic controller (PLC)) after pressure realizes energy control for need.In integrated oxidation ditch
Activated sludge, a part persistent loop, another part then flow to secondary settling tank together with sewage.The effect of secondary settling tank is to make to mix
Liquid clarification is concentrated to realize that sludge separates, and the sludge being separated temporarily is stored in sludge pump sump.The water outlet of secondary settling tank enters
Efficient sedimentation tank makes the further flocculation sedimentation of the particulate matter in sewage by adding PAC and PAM medicament.Add after efficient sedimentation tank
Filtering cloth filtering pool is in order to stop the suspended matter after flocculation sedimentation in sewage, to remove total solid suspended matter, total phosphorus and heavy metal.
Disinfecting tank is gone out by chlorination removes the viral germ of influence environment in sewage, keeps processed sewage up to standard
Discharge.The activated sludge of sludge pump sump is temporarily stored in addition to a part flows back into integrated oxidation ditch, it is most of with remaining dirty
The form of mud is by injection sludge reservoir.However, needing since excess sludge water content at this time is still very high in sludge dewatering computer room
Further thickening is converted into the lower mud cake of water content, is finally again transported mud cake and grid slag outside factory together by transport vehicle.
Above-mentioned sewage disposal system, sludge treating system are fitted with corresponding set with each unit of blast aeration system
Standby and instrument and meter is to complete control and monitoring function.Here, control function can refer to the start and stop of control each unit equipment and turn
Speed enables entire process flow safely and conveniently to carry out, for example, controlling the operating and stopping and air blast of blender in oxidation ditch
The frequency control etc. of machine.And monitoring function can refer to using instrument and meter measurement, show and record entire process flow and equipment
Critical data.These data are both foundation and O&M people of the operation maintenance personnel according to water inlet with water outlet status adjusting process process
Member's optimization production process is to meet the energy-saving basis for waiting requirements.Present most of monitoring systems can be according to monitoring data
Abnormal conditions warning message is sent from trend operation maintenance personnel by the monitoring screen in Central Control Room.Table 1 gives at the sewage
Manage each component part and the possible warning message occurred related with equipment, the state of instrument and meter and show value of factory.
Table 1
Not only quantity is big for the warning message of the monitoring system of sewage treatment plant, but also complicated, generally has following features.
(1) alarm quantity is more.
Since sewage treatment plant is related to multiple systems, and each system includes multiple units and equipment and necessary survey again
Measuring appratus and instrument, in addition same instrument and meter might have it is multiple.For example, certain sewage treatment plant described in Fig. 5, oxidation
The impeller of ditch outer fissure has shared 8.Theoretically, the Various types of data of sewage treatment plant can be shown and note in monitoring system
Record.Correspondingly, by the suitable trigger condition of selection and bound threshold value, monitoring system shows the stateful and number with record
Alert if can be also arranged in value.Therefore, in the large and medium-sized sewage treatment plant of a high degree of automation, quantity meeting of alarming
Very much.
(2) alarm content is wide.
Since an equipment might have multiple monitoring data, intelligent instrument and meter may once measure multiple parameters,
Therefore, the content of alarm may be very extensive.For example, the content of frequency conversion air blower and alert correlation includes work electricity in table 1
Stream and frequency.In addition, pump used in the sewage treatment plant is both provided with local and long-range two kinds of control modes, and correspondingly, alarm
Information will also divide into local alarm and remote alarms.In order to guarantee that pump is in normal operating conditions with the motor in other equipment
And production process is gone on smoothly, can also be arranged the alarm of motor frequent start-stop, motor ultra-long time work alarm with it is multiple
Associated working status alert of motor etc..
(3) there are different types of warning messages.
In general, the type of warning message can be divided into two kinds, and one is Process Alarm information, another kind is equipment alarm
Information.The characteristics of former is alarmed is that equipment self-condition is good, but exceeded situation occur in certain productions, need to make production
Adjustment.The characteristics of latter is alarmed is equipment due to longtime running, aging or operation maintenance personnel misoperation etc., goes out equipment
Existing performance decline or damage, lead to its partial failure or are unable to run, but relevant production run is normal.
(4) there is association between multiple alarms.
When having multiple warning messages while occurring, there may be incidence relations between part or all of warning message.Example
Such as, there is direct relation between the working condition alarm and oxidation ditch DO (dissolved oxygen) Threshold Alerts of frequency conversion air blower.Because may
It stops working just because of air blower, causes oxidation ditch aeration insufficient, the content for having in turn resulted in dissolved oxygen in oxidation ditch is too low.
When resuming operation for air blower, into oxidation ditch, aeration quantity increases, and not only blower frequency setting alarm can release, but also aoxidize
Ditch DO Threshold Alerts can may also release therewith.
(5) alert process has anxious slow.
When multiple alert if are triggered, some more urgent alarms need priority processing, and others are alarmed, right
Actual production influence is smaller, can will be placed in the processing priority that it is handled below.For example, if air blower stppage alarm with
Oxidation ditch outer fissure impeller stppage alarm occurs simultaneously, then the necessary priority processing of air blower stppage alarm, otherwise may cause
It is exceeded in turn result in water outlet for hypoxgia for aeration zone.And oxidation ditch outer fissure shares 8 impellers, some impeller failure, it is right
The influence of production technology can be smaller.
Based on association existing between multiple warning messages, after some warning message is processed, it is associated therewith its
He can then automatically terminate warning message, mathematically, this incidence relation between multiple warning messages can be abstracted as cause and effect
Relational graph.Here, not only quantity is big for the alarm being related to due to sewage treatment plant, but also alarm content and type of alarm are also more, this
It is very big to will lead to causality figure.If retrieving or modifying warning message based on the causality figure, calculating will lead to
The time-consuming of machine processing increases, and also adds the difficulty to alarm information processing, reduces the efficiency of alert process.
For this purpose, in exemplary embodiments of the present invention, based on the possibility causality figure next life between multiple warning messages
At alert process sequence, and alert process sequence is supplied to operation maintenance personnel and is referred to, to reduce the difficulty of alarm information processing
Degree, improves the efficiency of alert process.
Fig. 6 shows the corresponding system topology figure of three systems shown in fig. 5 according to an exemplary embodiment of the present invention.
Here, in order to keep figure clear, the warning message of part components and instrument and meter in table 1 is only listed in Fig. 6.
For example, possibility causality the figure PCRG, PCRG=(V, E) of multiple alarms are a digraphs, wherein V is section
Point set, node vi(vi∈ V) indicate a warning message；E is side collection, side eij=< vi,vj> ∈ E is one by node viRefer to
To node vjDirected edge, indicate warning message viWith warning message vjBetween possibility causality, that is, warning message vj's
Generation possibly relies on warning message vi。
Here, warning message vjGeneration possibly rely on warning message viMean warning message viReleasing may promote
Make warning message vjIt releases, it is also possible to not interfere with alarm vj.This phenomenon is physical presence in sewage treatment plant, for example,
There are possible causalities between stopping alarm and the alarm of oxidation ditch outer fissure DO lower limit simultaneously for two air blowers.There is oxidation ditch
The alarm of outer fissure DO lower limit, this illustrates that the content of dissolved oxygen in outer fissure is too low.This may be since what is supplied to outer fissure only has two
Air blower all stops working, it is also possible to due to influent load is excessive, returned sludge is very few or alarm DO instrument damage etc. other
Reason.If the alarm of oxidation ditch outer fissure DO lower limit is as two air blowers while caused by shutting down, two air blowers restore
After a period of work, it being increased to normal level to the dissolved oxygen of outer fissure, the alarm of oxidation ditch outer fissure DO lower limit can automatically terminate, and
Without other operations.Caused by if the alarm of oxidation ditch outer fissure DO lower limit is the other reasons other than shutting down as air blower,
Even if two air blowers are all resumed work, the alarm of oxidation ditch outer fissure DO lower limit is still had, and at this moment to be found other reasons, be made it
Release alarm.
Assuming that system to be analyzed is as shown in figure 5, the warning message occurred is respectively A1,A2,…,An(by taking n >=2 as an example).?
Before generating alert process sequence using above-mentioned fault alarm method, needed first to warning message A1,A2,…,AnContent carry out
Integrity detection, to ensure that the content of warning message is complete.
Fig. 7 shows the exemplary diagram of possible causality figure according to an exemplary embodiment of the present invention.
In the present example it is assumed that the monitoring system of sewage treatment plant detects following 4 warning messages:
A, oxidation ditch outer fissure DO lower limit is alarmed；
B, influent COD upper limit alarm；
C, it is discharged COD upper limit alarm；
D, 1# and 2# air blower while stopping alarm.
Moreover, it is assumed that the history alarm treatment sequence in history partial ordering relation are as follows: influent COD upper limit alarm < 1# and 2# drum
Blower while stopping alarm.
In the case, using above-mentioned 4 detected warning message, search graph 6 is to obtain between 4 warning messages
Possible causality figure (as shown in Figure 7).
In Fig. 7, the warning message that in-degree is 0 is influent COD upper limit alarm and 1# and 2# air blower stopping alarm simultaneously.
According to history partial ordering relation, obtain two warning messages processing order (that is, processing priority) be 1# and 2# air blower simultaneously
Stopping alarm is prior to influent COD upper limit alarm.
Then, deletion of node 1 (1# and 2# air blower while stopping alarm) and (the influent COD upper limit report of node 2 in Fig. 7
It is alert) and two associated sides of node.At this point, only node oxidation ditch outer fissure DO lower limit in possibility causality figure after beta pruning
Alarm and water outlet COD upper limit alarm, directed edge is alarmed by node oxidation ditch outer fissure DO lower limit is directed toward water outlet COD upper limit alarm, by
This can determine that the processing order of two warning messages is the alarm of node oxidation ditch outer fissure DO lower limit prior to being discharged COD upper limit report
It is alert.
Pass through above-mentioned treatment process, it may be determined that go out the processing priority of 4 warning messages by the alert process sequence after arriving first
Be classified as: 1# and 2# air blower simultaneously alarm prior to influent COD upper limit alarm prior to oxidation ditch outer fissure DO lower limit by stopping alarm
Prior to being discharged COD upper limit alarm.
Preferably, producible alert process sequence is supplied to the monitoring system of sewage treatment plant, with other alarm contents
It is shown in monitoring system simultaneously.As an example, the processing order of each warning message of numeral mark can be used, or directly
It is arranged according to the processing priority of each warning message by the processing order after arriving first.
However, the present invention is not limited thereto can also show alert process sequence, for example, using list by other means
Form or patterned mode show alert process sequence.
For 4 warning messages shown in Fig. 7, the reason for causing one kind of alarm most possible is sewage treatment plant's distribution
Between to air blower power main circuit fuse be blown, and intake at the same there is over-standard phenomenon.In a practical situation, once
The main circuit fuse powered to air blower is blown, and all air blowers stop working immediately, and monitoring system detects air blower
It shuts down, 1# and 2# air blower stopping alarm simultaneously can be issued.Air blower stopping will cause a series of chain reaction.If air blast
Machine is not supplied to the aerobic zone of oxidation ditch, and the dissolved oxygen concentration of oxidation ditch outer fissure can decline.Once the dissolved oxygen of oxidation ditch outer fissure
Concentration is lower than some value, can trigger the alarm of oxidation ditch outer fissure DO lower limit.And oxidation ditch aerobic zone for hypoxgia, and can to live
Property sludge in microorganism be difficult to keep it is enough activity to decompose the pollutant in sewage, this will cause water outlet pollutant level
It is exceeded, triggering water outlet COD upper limit alarm.If the COD intake at this time occurs exceeded again, and pollutant in sewage can be made into one
Step increases, and more microorganisms will require more oxygen, and making this, insufficient dissolved oxygen concentration further declines, accelerates oxidation
The alarm of ditch outer fissure DO lower limit.Equally, the pollutant increased can also be accelerated to be discharged COD upper limit alarm.
For above situation, sewage treatment plant's management and the correct disposal process of operation maintenance personnel should be: firstly, more renewing
Main circuit fuse, restore the power supply to air blower；The exceeded reason of influent COD is searched again, prevents the dirt of big load in time
Water discharge；Whether the DO instrument and water outlet COD instrument for finally checking oxidation ditch outer fissure work normally, if cisco unity malfunction, then tie up
Repair processing.
Fault alarm method according to an embodiment of the present invention, in the case where obtaining multiple warning messages, to assist sewage
Treatment plant's management and operation maintenance personnel emergency disposal alarm problem provide strong help.
Further, it should be understood that not repaired, oxidation ditch outer fissure if the DO instrument of oxidation ditch outer fissure is faulty always for a period of time
Just stopping alarm does not have causality to the alarm of DO lower limit simultaneously with 1# and 2# air blower, at this point, finally reprocessing oxidation ditch outer fissure
The alarm of DO lower limit may be more suitable.Therefore, in actual use, the management of sewage treatment plant and operation maintenance personnel need to be according to reality
Situation carrys out flexible Application based on alert process sequence provided by fault alarm method of the invention, to realize to alarm failure
Quick processing.
It should be understood that exposed for sewage disposal system, sludge treating system and air blast in above-mentioned cited embodiment
What the sewage treatment plant of gas system composition was introduced, and only list several warning messages of limited quantity.But the present invention
Shown in fault alarm method be not limited only to the part system and warning message of above-mentioned sewage treatment plant, for sewage treatment plant
Other systems and warning message be also it is applicable, the present invention no longer illustrates this one by one.
