Description
Technical field
The present invention relates to Automation of Electric Systems scheduling field, especially relate to the interface communication mode of the intelligent program-controlled anti-error system of a kind of cross-platform electrical network and method of operating and this system.
Background technology
" two tickets " just is meant " work ticket " and " operation order " general designation, and it is effective measures guaranteeing the dispatching of power netwoks safe operation." work ticket " is the writ that allowance is worked on electrical equipment or circuit, being clear and definite security responsibility, carrying out the written foundation that safety was told somebody what one's real intentions are, fulfiled the work permit formality, implements technical safety measures to the operating personnel, is the formality that work is interrupted, shifts and terminate.Therefore, when on electrical equipment or circuit, working, work ticket should conscientiously be used on request or by command execution." operation order " is " grid switching operation bill " again, is to forward electrical equipment to written foundation that the sequence of operation of another kind of state procedure is write as from a kind of state, must be capable by ticket stubs during operation.
Data shows that 300 hidden danger, dangerous matter sources, habitual violating the regulations are arranged, and 30 accidents just might occur, comprising general accident.30 accidents just may cause a particularly serious accident, are exactly usually said " 300: 30: 1 " safe iceberg theory.In the operation of power networks, the yardman is the person of making a final check of equipment and personal safety, and the yardman in a single day operation order maloperation, the permission of work ticket mistake or work is taken place do not finished mistuning degree situations such as misdelivery electricity, and the major accident that the dead group of group hinders just might take place very much.Scheduling operation ticket generation at present, operating process, work ticket admission process and work ticket finish to send electricity etc. by people's monitoring, because there is labile factor in the people, as easy as rolling off a log generation mistuning degree accident.
Scheduling " two tickets " is effective measures guaranteeing the dispatching of power netwoks safe operation.Along with the expansion day by day and the complexity of electrical network, the dispatching services amount also significantly increases thereupon, under existing human resources condition, how to prevent to cause greatly because of workload the appearance of mistuning degree accident, becomes a great problem of pendulum in face of all yardmans.In addition, under the situation that does not have effective anti-error scheduling measure at present, the labile factor on the individual spirit has also become the serious potential safety hazard of management and running.
At present the common operation bill system can be divided into 4 classes: based on production system mode, inquiry make out an invoice mode, subroutine module mode, figure check the mode of making out an invoice, based on switch control logic mode and object-oriented way.
Inquire about the mode of making out an invoice: Operation Ticket Expert System is utilized the database maintenance technology, and the operation order content is safeguarded.Its mode of making out an invoice is similar to on-the-spot manual bill mode, all is to be benchmark with " historical typical case " ticket when making out an invoice, and system does not have reasoning process, and whether the content of operation that can't discern the text of storing is correct, do not have intelligent.Because the historical ticket of various places is not the same, thereby this type systematic does not have versatility.
Based on the production system mode: the working rule in the Operation Ticket Expert System adopts production rule system, and " IF condition THEN conclusion " relatively near people's the mode of thinking, expression-form is simple and clear for this method for expressing.This class expert system operation interface is not too friendly, does not possess the intuitive operation effect.The user can't safeguard, can not adapt to the on-the-spot requirement that changes, and has influenced on-the-spot use; It is very big to be transplanted to other application repeated workload, and versatility is relatively poor.
Figure is checked the mode of making out an invoice: Operation Ticket Expert System has extremely friendly user interface, first and second wiring diagram of its operation interface simulation electric system, and graphing capability is powerful, possesses operating effect directly perceived, true to nature.It has checks function preferably, is suitable for the on-site training dispatcher, is a kind of widely used stimulating and training system.But it can not go out the operation order content by automated reasoning.
Based on the Object-oriented Technique mode: Operation Ticket Expert System has been used the Object-oriented Technique in the software field, makes that the exploitation at graphics edition interface is more efficient, flexible and easy.But for Operation Ticket Expert System, main is the automatic generation reasoning of carrying out operation order. and existing object-oriented expert system just all is abstracted into class to all electrical equipments, the good characteristic of Object-oriented Technique has not been given play in such representation of knowledge fully, and the carrying out of not exclusively suitable reasoning, the system maintenance of developing is very poor.
The scheduling operation bill system of on-the-spot utilization is one-of-a-kind system mostly at present, only can carry out reasoning to some typical operation orders and form automatically, mostly is " writing on one's behalf with machine " for the complex operations task, or typical ticket is made amendment.Along with power system development, demonstrated the limitation of its function, as failed to merge with real-time SCADA system, data and not corresponding, secondary maintenance workload in real time greatly, fail in operating process, to play anti-error effect etc.

Embodiment:
Native system mainly generates two most of compositions of subsystem, " two tickets " ADMINISTRATION SUBSYSTEM by the intelligence operation ticket, and the various piece coordinate operation complements each other, mutual restriction, forms the intelligent program-controlled anti-error system of cross-platform electrical network jointly.
Fig. 1 is the functional structure chart that the intelligence operation ticket of present embodiment generates subsystem, as can be seen from the figure, intelligence operation ticket under the EMS system of present embodiment generates subsystem based on the OPEN-3000 support platform, every function and service that it provides by platform, share real-time SCADA model and figure fully, attitude and simulation attitude data are reliably isolated in real time, have guaranteed the safe, real-time, reliable of whole process.It has realized the wiring Model Identification of topology Network Based, make out an invoice the rule the yardman or the telemechanical personnel from the customization, the intelligent inference of operation order, business form freely customize the flexible switching of the multiple mode of making out an invoice, the Whole Course Management of operation order life cycle; It adopts figure ticket integrated technique completely, promptly makes out an invoice among the figure, carries out in the ticket, has improved the visuality and the intuitive of the whole running life cycle of operation order; Strict based on the anti-verification scheme of system topological five and perfect rights management mechanism realize that operation order is intended ticket, audit, sends out in advance, carried out, the checking on man-machine associating of monitoring, thereby on to greatest extent, ensure the safe and stable operation of electrical network.
Therefore database owing to the database server of network security reason SAP system can't be visited the EMS system adopts data base link and trigger to obtain the data that the EMS system spreads out of in real time at the web of EMS system server end.Data stream is as follows:
A, at EMS system generating run ticket, and be saved in the EMS database;
B, EMS database are published to the web database with secondary data;
C, set up in the web database and lead to SAP system database data in server storehouse link and trigger, the passage of setting up by data base link passes to the SAP database with trigger with data in real time;
D, be inserted in " two tickets " system's table after in the SAP database, data being changed, login that the SAP system can see and the editing operation ticket data this moment.
Because the data volume of every ticket is very little, the time-delay that this series operation produces in LAN environment can be ignored, and that is to say the effect that can reach real-time butt joint.
Intelligence operation ticket generation subsystem based on the OPEN-3000 support platform has following major function:

(4) external system interface
Interface with systems such as DMIS systems is provided, and operation order transmits automatically, and the native system operation order is sent to other department by network mode where necessary, sends to the scheduling attended computer by mis system.
The intelligence operation ticket generates subsystem and adopts figure ticket integrated technique, and the basic process that figure is made out an invoice as shown in Figure 2.Wherein mainly comprise processes such as network topology, wiring Model Identification, regular intelligent inference, system topological five anti-verifications, action statement generation, operation simulation.Idiographic flow is as follows:
Switch to simulated operation environment and initialization after entering the operation order administration interface, click or multiselect equipment according to graphic picture, operation task is discerned automatically, select one or more operation tasks after, the operation order intelligent inference passes through the system topological verification then.
If pass through, then form the operation order statement, the line operate ticket of going forward side by side simulation sends to administration interface with operation order then.
If do not pass through, then return graphical interfaces, click again or multiselect equipment.
The wiring Model Identification is the basis of realizing the intelligence operation ticket.The main cause why yardman can manually make out an invoice is the attribute information of the mode of connection, the method for operation and each equipment that the yardman can automatic analysis system, decides the sequence of operation of equipment under the different modes of connection and the method for operation then according to the formed expertise of schedule regulation.Therefore want to realize at first will possess wiring Model Identification function by the intelligence operation ticket.
The wiring Model Identification mainly is according to the network topology analysis, feature according to equipment connecting relation, automatically analyze the attribute information of the mode of connection, the method for operation and the equipment of current system, utilize these information to remove the match user custom rule, thereby realize the intellectuality of operation order.
Equipment state mainly refers to operation, stand-by heat, cold standby, overhauls, closes, grades.By the identification equipment state, the operation task that can decision device can carry out, thus be filled into the operation task that equipment cannot be carried out, simplified the probability of yardman's selection and maloperation.In the process of rule-based reasoning, also need to decide the success or not of the flow direction and the operation task coupling of reasoning simultaneously according to the conversion of equipment state.
The conversion rule of the electrical equipment state of electric system is operation-stand-by heat-cold standby-maintenance or maintenance-cold standby-stand-by heat-operation.Corresponding operation task has by operation changes stand-by heat, is changeed cold standby, changeed maintenance or the like by operation by operation.Also have in addition switch, disconnecting link and ground connection disconnecting link disconnection, close and operation task such as inspection.Even if commentaries on classics mode, the operation of falling the bus etc. also are the set of above-mentioned these operation tasks.By the relation between these operation tasks is analyzed, has nest relation as can be seen between the operation task.Change the operation of cold standby by operation such as switch.
Fig. 3 is the regular framework synoptic diagram that present embodiment intelligence operation ticket generates subsystem, and as can be seen from the figure, each operation task both was made up of other operation tasks, and it also may be an operation steps of other operation tasks simultaneously.Native system is the contextual definition between the operation task among Fig. 3 regular framework.Yardman or telemechanical personnel can custom rule framework, the just nest relations between the self-defining operation task.Expertise is dissolved into is guaranteed the correctness of making out an invoice in the definition of regular framework.
After the rule framework was set up, what intelligent inference was mainly realized was the operation task of selecting according to the yardman, and the operation task of search rule framework definition according to the result of wiring Model Identification, is carried out the coupling of operation task and the replacement of operating equipment step by step.Finish when the strictly all rules framework all mates, then operation steps has just generated automatically.Because therefore the nested property of regular framework adopts recursive algorithm when realizing.
" five is anti-" is to prevent that the reliable assurance of maloperation from appearring in electric system.As one of the basic function of DAM (SCADA subsystem) in the energy management system (EMS system), many EMS system all possesses the Remote function.In order to ensure the security and the correctness of straighforward operation, need when carrying out straighforward operation, carry out " five is anti-" verification.
It is anti-that present embodiment has been introduced system topological five based on the intelligence operation ticket generation subsystem of EMS system, and power network topology and " five is anti-" rule are combined the operation locking of realizing equipment room.It does not rely on artificial definition.Have good versatility and non-maintaining property.Can realize simultaneously the operation locking between whole network equipment.The anti-whole life through operation order of system topological five from making out an invoice, simulate, preview execution to the end, and can not rely on operation order and five anti-verifications during separately as remote control are used.
Electric operation in the electric system mainly is the operation of switch, disconnector and ground connection disconnecting link, and therefore " five is anti-" also is at these several operations of equipment.Below be the topology five anti-rules that native system requires according to " five is anti-".
(1) the topology five anti-rules of switch
Because switch is the equipment that cut-offs with arc extinguishing ability, mainly be to prevent mistake deciliter switch at switch in " five is anti-" therefore.
Fig. 4 is the wiring diagram that present embodiment switch topology five is prevented, is the topology five anti-rules that example sums up the present embodiment switch below with Fig. 4.
1) if after switch disconnected, the switch ends node did not have other connection branch road, then points out the yardman, in order to avoid mistake deciliter switch.
Among Fig. 4, operation task was 2030 generations 2243, if bypass does not drop at interval, 22433 do not close, then 2243 disconnect after, its two end node will not have other to be communicated with branch road, will cause the circuit dead electricity, therefore point out the user in order to avoid mistake deciliters 2243.
Equally, when 2243 resume operation, if 2243 put into operation at interval and just do not disconnect 2203 switches, then 2230 liang of end nodes will not have other to be communicated with branch road, and also can cause the circuit dead electricity this moment, therefore can point out the yardman equally in order to avoid mistake deciliters 2230.
(2) the topology five anti-rules of disconnector
With respect to " five is anti-" of switch, " five is anti-" more complicated of disconnector prevents that band ground cutter from closing disconnector, preventing two of on-load drawing disconnectores.Be the topology five anti-rules that example sums up disconnector below with Fig. 4:
1) if the arbitrary end node of disconnector belongs to the ground connection island, then do not allow closing operation.In order to avoid band ground connection is closed disconnector.
Among Fig. 4,2243 maintenance, 2243C0 and 2243B0 close, and 2243 liang of end nodes all belong to the ground connection island, and same, an end node of 22431,22432,22433 also belongs to the ground connection island.When 2243 maintenance finish, under the situation that 2243C0 and 2243B0 do not draw back, will forbid closing 22433,22431 or 22432, avoid being with ground connection to close disconnector.
If 2243C0 draws back, although 22431,22432 liang of end nodes do not belong to the ground connection island, but because switch is not tangible cut-off point, therefore need the supposition switch to close, again carrying out power network topology and electric island analyzes, this moment, 22431,22432 liang of end nodes still belonged to the ground connection island, also forbade closing 22431 or 22432.
Prevent that closing disconnector with the ground cutter is one of anti-maximum characteristics of system topological five.
2) if arbitrary switch that disconnector directly links to each other is closing the position then is not allowing isolator operation; If disconnector does not have the switch that directly links to each other, its switch that links to each other indirectly of deep search then is not if arbitrary switch allows disconnecting switch operation closing the position yet, in order to avoid on-load drawing disconnector.Notice that the search border is a switch, promptly search the continuous recently switch of disconnector and promptly stop.
22431,22432 and 22433 direct-connected switches are 2243 among Fig. 4, if 2243 switches are closing the position, then forbid the branch closing operation.
Fig. 5 is present embodiment topology five anti-disconnector wiring diagrams, and as can be seen from the figure, 1011 direct-connected switches are 101, as long as 101 can operate in minute position.Therefore and for 1111,1214 and 1224, they do not have direct-connected switch, and the switch that connects in succession therebetween of search is 101,102 and the switch at opposite end factory station.Arbitrary switch is closing the position, will forbid 1111,1214 and 1224 branch closing operation.
Fig. 6 is another topology five anti-disconnector wiring diagrams of present embodiment, and as can be seen from the figure, transformer high-voltage side 1034 disconnecting links directly do not connect switch, and therefore the switch that connects in succession therebetween of search is 503 and the opposite end factory switch of standing.Arbitrary switch is closing the position, will forbid 1034 fens closing operations.
(3) topology five of ground connection disconnecting link is anti-
By the system topological analysis, electrical network is decomposed into island alive and ground connection island.If an end node of ground connection disconnecting link is for living island then forbid the closing operation of ground connection disconnecting link, in order to avoid charged splice grafting ground disconnecting link.
With Fig. 4 is example.If 2243 at interval in running status, then the node of 2243C0 and 2243B0 belongs to island alive, forbids 2243C0 and 2243B0 closing operation this moment.
In the EMS system, the dispatcher is provided with the ground connection nameplate on the figure of being everlasting, and replaces the ground wire in the reality, to do caution.The effect of ground wire is identical with the ground connection disconnecting link, therefore will consider the influence of ground connection nameplate in system topological five is prevented.
Fig. 7 is a present embodiment ground connection nameplate synoptic diagram, and as shown in Figure 7, when the dispatcher is provided with the ground connection nameplate on switch, system will increase a virtual ground disconnecting link.The node number of this ground connection disconnecting link equals arbitrary end node number of switch, and the electric island attitude of revising this node then is the ground connection island.When the dispatcher deletes this ground connection sign board on picture, system will delete this virtual ground disconnecting link, and remodify the state on each electric island.In this process, do not need to carry out again topological analysis.
It should be noted that disconnector is tangible cut-off point in electrical equipment, the ground connection board is arranged on that the influence to electric island attitude is different on each side gusset of disconnector.But present EMS only is supported on the equipment and lists, and is not supported on the device node and lists, and does not therefore list on disconnector generally speaking.List on the equipment that solution is with disconnector links to each other.
EMS is a complexity and huge system, and the correctness and the integrality of real-time information are most important.When carrying out the anti-verification of topology five, system default is based on full mesh topology and carries out verification, the operation of equipment at this moment not only and the operation locking relation arranged between this station equipment, also and the equipment at other factories stations have operation locking to concern.But when system's real-time information is imperfect, the check results that may lead to errors.At this moment provide the our station topology five anti-functions.
Homologous ray topology five is anti-carries out five anti-verification differences based on full mesh topology, and our station topology five is anti-only carries out topological analysis to this station equipment, carries out five anti-verifications based on the electric island attitude and the equipment connecting relation of our station.
The our station topology five anti-five anti-rules that adopt are anti-identical with system topological five, and difference is the search border of topological analysis.In electric system, stand with the station between be communicated with by circuit, so our station topology five anti-search borders are circuits, promptly search circuit and promptly stop, and will not have connected relation also not have the operation locking relation like this between station and the station equipment.
Native system provides flexible switching mode, the yardman can be as required anti-and system topological five switches between anti-in our station topology five.
The yardman has dual mode when the executable operations ticket.A kind of is directly to carry out on nominal value, and a kind of is on figure equipment to be carried out straighforward operation.In order to prevent not operate by the operation order order, native system provides the sequence of operation verifying function.According to yardman customization, not only can carry out anti-errorly according to current sequence of operation at all tickets of doing, can also carry out anti-error according to the concrete sequence of operation of every operation order.
Native system topology five prevents having following characteristics:
(1), is different from traditional transformer station five anti-devices, system topological five is anti-by the state on the electric island of topological analysis and the annexation of equipment room, prevent rule according to the topology five that " five is anti-" requires highly to summarize switch, disconnecting link and ground connection disconnecting link, do not need the operation locking relation between the artificial define equipment of yardman.Have good versatility and non-maintaining property.
(2), system topological five prevents having tradition five anti-incomparable advantages when judging band ground connection and disconnecting link.
(3), system topological five is anti-not only can be used in straighforward operation time the five anti-verifications, writing, also can carry out system topological five anti-verifications in the executable operations ticket, thereby guaranteeing the correctness and the security of operation order.
The intelligence operation ticket generates subsystem and obtains the element real-time status and by cross-platform and client---server mode designs from data platforms such as SCADA/EMS.System only needs the yardman to check the related elements state when automatic generating run ticket; System provides imperative operation ticket audit function so that newly-generated operation order is examined.The native system friendly interface, the multiple mode of making out an invoice that is had can be replenished mutually, can alleviate yardman's workload and the security that improves operation greatly.
The running of system starts from the formulation and the typing of turnaround plan, and roughly flow process as shown in Figure 8.
At first, method of operation group basis is scheduled overhaul or ad hoc inspection and repair situation then, the executive plan of arrangement equipment interruption maintenance day degree, overhaul single typing by overhaul management module, finish the required mode of overhaul of the equipments and the guaranteed request that continues jointly together with the guarantor's group that continues then, enter the execution flow process after the relevant specific responsibility audit of process is qualified, be delivered to the dispatching terminal workstation.
The mode requirement that yardman on duty is single according to maintenance, according to SCADA real time data and field apparatus running status, the selected equipment that needs to change maintenance, and selection equipment by a kind of state exchange to another kind of state, the intelligence module of drawing a bill just can be provided the required scheduling operation ticket of yardman according to actual needs.
Then the operation order of providing is sent to the SAP system platform, in the workflow management module that operation order is single with maintenance, worked that it is related to carry out, to realize the mutual latching relation between " two tickets ".
Operation order is sent to the long workstation of total value, by total value length on duty operation order is examined, and then sends it back the despatching work station of drawing a bill if any problem and makes amendment, and is entirely true up to operation order so back and forth, and the time carries out as requested in scheduling on duty then.
In the process of implementation, each all has fixing logic familiar, and project before and after the program meeting locking never allows to jump item, a leakage operation.
In the power failure process, before the power failure operation order is not finished, the work ticket that system does not allow scheduling grant on duty scene to go into operation; When the telegram in reply operation, do not handle the termination formality as yet as the work on the spot ticket, system does not allow to carry out the operation order of telegram in reply, thereby reaches the relation of mutual locking, thereby guarantees the security of scheduling operation.
Fig. 9 is the power failure operational flowchart of present embodiment, and as can be seen from the figure, the power failure flow process of present embodiment is as follows:
(1), in the SAP system, submits work ticket to;
(2), examination ticket in the SAP system;
(3) if audit is passed through, then related relevant maintenance is single in the SAP system, if audit not by return step (1);
(4), by the operation order generation system operation order that goes out to have a power failure, after first trial is qualified, preserve and send this power failure operation order to the SAP system;
(5), related relevant maintenance list or emergency service are single in the SAP system;
(6), whether guardian's review operations ticket qualified, if qualified then the guardian confirms signature, if defective then return step (4);
(7), whether responsible official's review operations ticket on duty qualified, if concurrent master/distribution if responsible official qualified then on duty confirms to sign is defective then return step (4);
(8), possessing operating conditions operates by ticket;
(9), send total value long filing after the operation;
(10), fill in power off time;
(11), master/distribution permission work ticket.
Figure 10 is the telegram in reply operational flowchart of present embodiment, and as can be seen from the figure, the telegram in reply flow process of present embodiment comprises:
A, telegram in reply operation order flow process, this telegram in reply operation order may further comprise the steps:
(a), generate the telegram in reply operation order, after first trial is qualified, preserve and send this telegram in reply operation order to the SAP system by the operation order generation system;
(b), related relevant maintenance list or emergency service are single in the SAP system;
(c), whether guardian's review operations ticket qualified, if qualified then the guardian confirms signature, if step (a) defective then Returning process A;
(d), whether responsible official's review operations ticket on duty qualified, if concurrent master/distribution if responsible official qualified then on duty confirms to sign is step (a) defective then Returning process A;
(e), possessing operating conditions operates by ticket;
(f), the operation back is from the long affirmation of total value errorless back filing;
(g), filling in the single telegram in reply of maintenance filed after the time.
B, power cut-off ticket flow process, this power cut-off ticket flow process may further comprise the steps:
(a), the SAP system accepts the power cut-off ticket;
(b), the licensor confirms that the work ticket related work is all over and the power cut-off ticket, if then enter next step, if otherwise the step of Returning process B (a);
(c), responsible official on duty confirms that the work ticket related work is all over, operate by ticket if then possess operating conditions, if otherwise the step of Returning process B (a);
(d), the operation back is from the long affirmation of total value errorless back filing;
(e), filling in the single telegram in reply of maintenance filed after the time.
One of main mode that intelligence operation ticket generation subsystem is drawn a bill as operation order.Because it can only satisfy and draws a bill, print tickets sample etc. function, and can not with present work ticket, business datum such as maintenance is single carries out that logic is mutual, information sharing, has formed information island, also is unfavorable for the construction of schedule informationization.This just need have an operation ticket system to satisfy the needs of daily production in comprehensive business system.In this cover system, owing to need and use the service integration system combination in several years originally, and accomplish information compatibility, information sharing, so we adopt code platform and the data platform consistent with former comprehensive business system technically.But because intelligence operation bill system and operation system are the products of two cover different vendors, it is bigger directly using the interface expense in program.So the data that employing is carried out intelligence operation ticket generation subsystem and " two tickets " ADMINISTRATION SUBSYSTEM alternately by the ORACLE data of database exchange.The intelligence operation ticket generates subsystem and write " two tickets " ADMINISTRATION SUBSYSTEM necessary operations ticket data in public, an open form.After writing data, adopt the database trigger mode to check data correctness, after checking out with this data importing or be updated in the service integration system.And then in database, adopt the mode of operation regularly to delete the data that sent to the service integration system, and prevent that this opening form capacity is excessive, take excess resource.Operation order in the service integration system after receiving these information, with automatic demonstrating data at user platform.This has also realized the seamless link of two systems very easily.
In order to prevent the existence of potential safety hazard such as maloperation, need in system, control the precedence on maintenance list → work ticket → operation order three operation steps.The incidence relation that artificial related maintenance list → work ticket → operation order (maintenance list → work ticket) is at first arranged is because only relevant having gone up concerns the logical relation that could control three kinds of tickets technically.What operation order was taked is the mode of three-step-march.Receive data from intelligence operation ticket generation subsystem after, according to the execution sequence of sequence number generating run ticket at par, term by term combination is carried out and the purpose of order execution to reach with automatically.Automatically the related maintenance of prompting is single, because the execution of operation order must have maintenance single.After the association maintenance was single, operation order just can enter the workflow of manual examination and verification, examination.In this two steps workflow, monitoring the single and present progress degree of work ticket of related maintenance always.In workflow, adopt with the identical development platform of SAP system, can formulate the present residing duty of ticket accurately, no matter enter next flow process and return a last flow process and all can have influence on other related tickets.In the workflow of maintenance list and work ticket, also monitoring the progress degree of operation order simultaneously.In order to prevent maloperation, each step operation of these three tickets all will be made the control that allows operation and do not allow to operate according to the progress of all the other two parts of tickets.This wherein mainly is to control according to the present state of every part of ticket in the ORACLE database and judge technically, has wherein also used on some field data value and has judged.When can judge accurately draw a bill and ticket between relation after, just can reduce the scheduling production safety hidden danger that produces because of maloperation to the full extent.
The project implementation of operation order has a lot, and execution arranged side by side is arranged, and has to jump an execution, also has in order and carries out.This just might increase accident rate because of maloperation in the process of implementation.In order to reduce potential safety hazard, must its execution sequence of control.In order to reach this purpose, present embodiment has increased the control to each operation item current state of operation order on the database aspect, and the control of operation item execution sequence.The purpose that increases State Control is revised for the operation item that prevents to have operated by mistake, the mistake deletion.The purpose that increases execution sequence be for better between the control operation ticket operation item in order, made by issuing an order in each operation item and report such one hurdle, order one hurdle of three-step-march, carry out one by one.So also reduced the accident that causes because of the mistake on the order.
For preventing the problem that server crashes in operating process, occurring, the special design of native system has the function of " being saved in this locality automatically ", it can be with the operation order automated back-up in the operating process to yardman's on duty computing machine, so that print written ticket operation when server crashes.
Situation about can't draw a bill when exempting from intelligence operation bill system fault occurs, therefore present embodiment has also designed manual typing operation order function (banning use of generally speaking), so it is two autonomous systems that the intelligent intelligence operation ticket of EMS system generates " two tickets " ADMINISTRATION SUBSYSTEM of subsystem and SAP system, be again a unified system, being mutually independent also connects each other.
