The 7-2 of data collection portion of data library device 71 with communicator 61 by control net 90 send here generate (reproduction) plant data be stored in database 7-1.
The restore data that the restore data storage part 6-5 of restore data collection unit 7-3 collection communication device 61 sends here by control net 90, collected restore data also is stored in database 7-1.
The following describes running.
Fig. 2 is the flow chart of the running usefulness of set communicator 41 in the explanation far-end factory 21.Fig. 3 is the flow chart of the running usefulness of set communicator 61 in the explanation center system 11.Fig. 4 is the flow chart of the running usefulness of set data library device 71 in the explanation center system 11.
The running of the communicator 41 of far-end factory 21 at first, is described with Fig. 2.
The 4-2 of data collection portion of communicator 41 collects plant data (step S1-1) by control net 50.
Secondly, it is analogue data or the judgment processing of numerical data (step S1-2) that data generating unit 4-3 carries out collected data, when the data of collecting are numerical data, compare (step S1-3) with the value of last time, when the value of last time changes (data mode exists and changes, such as logical → disconnected, disconnected → when logical), proceed to step 1-6, and not when the value of last time changes, return step S1-1.
Again, when the data generating unit 4-3 of communicator 41 is analogue data in the data of collecting, calculate the data variation amount (step S1-4) of the value that departs from last time after, judge whether the variable quantity of calculating is predefined specified threshold above (step S1-5).
The variable quantity of calculating among the step S1-4 is predefined specified threshold when above (when data mode changes), proceeds to step S1-6, and this variable quantity returns step S1-1 when to be specified threshold following.
Analogue data that step S1-2 obtains handling to the step S1-5 and numerical data are processed into the state variation value (plant data change information) (step S1-6) in the moment of adding the generation state as the data that send to center system 11.
After this, data generating unit 4-3 verification and center system 11 communicate the state (S1-7) of fixedlying connected communication line 31 of usefulness.
Department of Communication Force 4-1 at fixedly connected communication line 31 just often, transmit status changing value (being the plant data change information) (step S1-8), when fixedly connected communication line 31 is unusual, after storing state variation value (plant data change information) in the communicator 41 restore data storage part 4-4 (step S1-9) as restore data, return step S1-1.
The communicator 41 of far-end factory 21 repeats above-mentioned processing, makes fixedly connected communication line 31 just often, only center system 11 is sent vicissitudinous data, and fixedly connected communication line 31 is when unusual, will be to the storage of center system 11 transmissions in inside.
Below, the running of the communicator 61 of center system 11 is described with Fig. 3.
The Department of Communication Force 6-3 verification and the far-end factory 21 of communicator 61 communicates the state (step 2-1) of fixedlying connected communication line 31 of usefulness.
Fixedly connected communication line 31 just often, the 6-2 of data collection portion receives in the communicator 41 of far-end factory 21 and processes the data (being the state variation value) (step 2-6) that the back sends, and the 6-4 of data reproduction portion is changed the state variation value that receives and generates the plant data (promptly being reproduced as plant data) (step S2-7) that monitoring arrangement 80 and data library device 71 can be discerned processing.
When fixedly connected communication line 31 is unusual, the unusual recovery (step S2-2) of Department of Communication Force 6-3 monitor communication circuit of communicator 61, fixedly connected communication line 31 restores, then the 6-2 of data collection portion collect fixedly connected communication line unusual during the restore data storage part 4-4 of communicator 41 far-end factory 21 in the restore data (step S2-3) of storing.
The restore data of the 6-2 of data collection portion being collected at the 6-4 of data reproduction portion is changed and is generated (reproduction) plant data (step 2-4).
Then, the data that the 6-4 of data reproduction portion is reproduced as plant data store the restore data storage part (step 2-5) in the communicator 61 into as the restore data that database 7-1 uses.
Then, the state (step S2-8) of Department of Communication Force 6-1 verification control net 90 at control net 90 just often, sends up-to-date plant data (step S2-9) to monitoring arrangement 80 and data library device 71.
When control net 90 was unusual, the plant data that will send object was as restore data storage (step S2-10).
Also at control net 90 just often, whether the Department of Communication Force 6-1 verification of communicator 61 receives restore data from data library device 7 and sends request (step 2-11), receives restore data and sends request, then sends the restore data (step S2-12) during this request.
The communicator 61 of center system 11 repeats above-mentioned processing, make system just often, monitoring arrangement 80 and data library device 71 are sent the up-to-date plant data that reproduces according to the state variation value of collecting from far-end factory, and in the time can not sending data unusually because of control net 90, with storage during this period to restore data storage part 6-5.
During from unusual recovery, collect the data of communicator 41 storages of far-end factory 21 at fixedly connected communication line 31 again, lose the data of (damaged) in the completion center system 11.
As shown in Figure 4, the data library device 71 that center system 11 is provided with at control net 90 just often receives plant data (S3-6), deposits database 7-1 (step S3-7) in.
Unusual at control net 90, can not be when communicator 61 receives plant datas, control net 90 restores the data (step S3-3 and S3-4) during back restore data storage part 6-5 collection from communicator 61 can not receive data, deposits database 7-1 (step S3-5) in.
Illustrated as mentioned, utilize the long-range plant supervisory system of this example, then between center system and the far-end factory just often (being to fixedly connected communication line just often), only the delta data with factory sends when changing as state variation value (plant data change information), thereby can reduce the data volume of communicating by letter significantly through fixedly connected communication line, as fixedly connected communication line, available arrowband and inexpensive wide-area communication circuit.
Take place when unusual at fixedly connected communication line, can store the state variation value (plant data change information) between anomalistic period in the far-end factory, thereby fixedly connected communication line recovers just often, center system is sent the state variation value (plant data change information) of storage, making can be according to " time information when plant data changes " that add on the state variation value, the plant data that completion is lost on sequential.
Example 2
Fig. 5 is the block diagram of composition that the far-end plant supervisory system of example 2 is shown.
Among this figure, 12 for concentrate monitoring and the center systems of the set a plurality of factories of control far-end that 22 be to concentrate a plurality of factories that monitor in center system 12, and 31 is the fixedly connected communication line that carries out center system 12 and the usefulness of communicating by letter of a plurality of far-end factory 22.
42 for being arranged on each far-end factory 22 so that carry out the communicator of communicating by letter with center system 12,4-1 is the Department of Communication Force that carries out with the communication process of center system 12,4-2 is for collecting the data collection portion of plant data, and 4-3 is the data generating unit that is arranged in the communicator 41 of each far-end factory 21.
The 50 control nets for the far-end factory 22 that is laid in connect (not shown)s such as far-end factory 22 interior communicators 42 that are provided with and monitoring arrangement.
62 for being arranged on center system 12 so that carry out the communicator of communicating by letter with each far-end factory 22,6-1 carries out and center system 12 interior each communication process Department of Communication Force that install, 6-2 is the data collection portion that carries out the collection and treatment of the data that a plurality of far-end factory 21 sends here respectively, 6-3 is for carrying out the Department of Communication Force with the communication process of a plurality of far-end factory 21 by fixedly connected communication line, 6-4 is the data reproduction portion that is arranged in the communicator 61 of center system 11.
80 is the monitoring arrangement that is provided with in the center system 12, and 8-1 is the display part that shows plant data on screen, and 8-2 is the data collection portion that carries out the plant data collection and treatment.
90 is the control net that lays in the center system 12, connects communicator 62 and monitoring arrangement 80.
The far-end plant supervisory system of above-mentioned example 1 has when unusual at fixedly connected communication line 31, restore data is stored into the communicator 41 of far-end factory 21, have when unusual at the control net 90 of center system 11, store restore data into communicator 61, thereby can prevent losing of database 7-1 that communication line causes unusually.
In contrast, the long-range plant supervisory system of this example as shown in Figure 5, the communicator 42 of far-end factory 22 and the communicator 62 of center system 12 are not provided with the restore data storage part.
Identical during with example 1, the plant data of the far-end factory that the data generating unit 4-3 that is provided with in the communicator 42 of far-end factory 22 collects according to the 4-2 of data collection portion generate send to center system 12 usefulness the state variation value after, the state variation value that generates is delivered to Department of Communication Force 4-1.
As indicated above, " state variation value " is meant that the plant data that data collection unit 4-2 is collected by some cycles compares data value and the new data value of collecting of last time, and when changing, make the information of " the plant data value of variation " interpolation " moment that this plant data changes " gained, be called " plant data change information ".
Again, the 6-4 of data reproduction portion of the communicator 62 that center system 12 is provided with is according to the state variation value of the 6-2 of data collection portion by each far-end factory 22 of fixedly connected communication line 31 collections, generate available plant data (promptly reproducing) in the center system 12 interior monitoring arrangements 80, and the plant data that reproduces is delivered to Department of Communication Force 6-1.
The long-range plant supervisory system of this example is when fixedly connected communication line 31 generations are unusual, and communicator 42 does not carry out the storage of restore data (promptly recovering the state variation value of usefulness), waits for being restored unusually of fixedly connected communication line 31.
Then, during being restored unusually of fixedly connected communication line 31, last state changing value (plant data change information) that will this moment (moment that promptly is restored unusually) to whole signals sends to center system 12 rear flank, identical during with example 1, the state variation value that data generating unit 4-3 is generated sends to center system 12 sides according to the order of sequence.
The state variation value that the 6-4 of data reproduction portion of the communicator 62 in the center system 12 sends according to the communicator 41 of far-end factory 22, reproduce available plant data in the monitoring arrangement 80, and the plant data that reproduces is sent to monitoring arrangement 80 by control net 90.
When 90 generations of control net were unusual, communicator 62 did not carry out the storage of restore data, waits being restored unusually of net 90 to be controlled.
Then, during control being restored unusually of net 90, last state changing value (plant data change information) that will this moment (moment that promptly is restored unusually) sends to monitoring arrangement 80 rear flank, identical during with example 1, the state variation value that the 6-4 of data reproduction portion is generated sends to monitoring arrangement 80 according to the order of sequence.
Illustrated as mentioned, utilize the long-range plant supervisory system of this example, then take place when unusual at fixedly connected communication line, do not store the state variation value (plant data change information) between anomalistic period in the far-end factory, even thereby fixedly connected communication line becomes normally, the plant data that changes during unusual can not completion in the center system takes place, but fixedly connected communication line just often, only vicissitudinous plant data is communicated (only transmit status changing value) when changing, thereby can further reduce the data volume that sends by fixedly connected communication line, as fixedly connected communication line, available further arrowband and inexpensive communication line.
And far-end factory and center system are not provided with the restore data storage part, thereby can reduce system cost.
Example 3
Fig. 6 is the block diagram of composition that the long-range plant supervisory system of example 3 is shown.
In the drawings, 13 is center system, and 23 is far-end factory, and 43 is the communicator of far- end factory 23, and 63 is the communicator of center system 13.
The long-range plant supervisory system of above-mentioned example 1, the state variation value that generates among the data generating unit 4-3 of the communicator 41 of its far-end factory 21, if fixedly connected communication line 31 is not unusual, then often send to the communicator 61 of center system 11, and for example the control net 90 of fruit center system 11 is not unusual, then will according to the state variation value data that plant data generates often be sent to data library device 71 and monitoring arrangement 80 6-4 of data reproduction portion of communicator 61 from communicator 61.
In contrast, the long-range plant supervisory system of this example, the communicator 43 of its far-end factory 23 generates the state variation value (plant data change information) of collected plant data in its data generating unit 4-3, and with the state variation value that generates all as restore data, store restore data storage part 4-4 into, even fixedly connected communication line 31 is normal, often do not send the state variation value that generates among the data generating unit 4-3 to center system 13 yet.
Again, carry out conversion according to the state variation value among the 6-4 of data reproduction portion of communicators 63 in the center system 13 and generate (promptly reproducing) for the data of plant data all as restore data, store restore data recovery section 6-5 into, even control net 90 is normal, often data storehouse device 71 and monitoring arrangement 80 are not sent the plant data that conversion also generates among the data reproduction 6-4 of portion yet.
