Description
Technical field
The present invention relates to the method in the Process Control System of coil of strip production line, be specifically related in coil of strip fabrication line process
In control system, the procedure level ensuring method that outlet coil of strip creation data is complete.Particularly relate to one build at outlet section
Under the key signal abnormal conditions of vertical steel roll production data recording, ensure, at procedure level, the side that coil of strip creation data is complete
Method.
Background technology
In the Process Control System of coil of strip production line, it is ensured that coil of strip creation data is completely Process Control System
One main task.
A usual coil of strip production line is made up of entrance, interlude and outlet section.The creation data of one coil of strip by
Process Control System is during strip steel is by each section, according to basic automation systems and control object detection system
The control signal sent and detection data are set up and complete.The exploitation of process control software it is engaged in for many years according to inventor
Experience, the control signal of outlet section is the most of crucial importance for whole strip steel creation data.
Generally, the creation data origin material data of coil of strip and target data, process actual achievement and become volume information
Constitute with statistical data etc..Process machine system, when coil of strip afterbody " shearing completes " signal arrives, generates coil of strip
Production data recording (supplied materials data and target data, process actual achievement, statistical data)；Batching " completing signal "
Rolling data are added during arrival；Then, when " unloading volume to complete " signal arrives, to corresponding with this coil of strip online
Data do processed offline.
But, it sometimes appear that fortuitous event: due to the reason such as equipment or external system it some times happens that outlet section
Control signal is imperfect, and such as shear signal does not has, and has only batched signal, or unloads volume signal and do not have etc..
These can be divided into 7 kinds of situations, extremely such as following table (yes represents that signal has, and no represents that signal does not has) in theory:
| Shearing completes | Batch | Unload volume to complete |
| yes | yes | no |
| yes | no | yes |
| no | yes | yes |
| no | yes | no |
| no | no | yes |
| yes | no | no |
| no | no | no |
These abnormal conditions can happen occasionally at the initial stage that production line newly puts into.Some exceptions can produce coil of strip finished product number
Do not generate according to record, or have record but the consequences such as scarce data.In this case need manually to be mended item by item by picture
Enter data to solve.Confiscating then especially for the signal setting up coil of strip creation data, data volume to be mended is relatively big,
Waste time and energy.Some exceptions also result in outlet and follow the tracks of abnormal, and current steel coil space occupying affects follow-up coil of strip and normally enters
Enter and the coupling of coil of strip plan.But reality process machine system before unloading volume signal processing has the process of outlet coil of strip
Data, if the sequential occurred by signal, are simulated unreceived signal and can greatly utilize these data automatic
Produce coil of strip creation data, efficiently solve this problem.
Summary of the invention
For above-mentioned defect of the prior art, the technical problem to be solved in the present invention is to provide a kind of coil of strip production line
The procedure level ensuring method that outlet coil of strip data are complete, when solving outlet abnormal signal, the most more fully generates steel
The problem of volume production data recording.

Specific implementation:
The procedure level ensuring method that coil of strip production line of the present invention outlet coil of strip creation data is complete, including outlet section signal imitation
Rule, outlet signal handler, simulation are unloaded volume and are completed picture.
Described outlet signal handler (can be as a part for data collection program), the following (ginseng of its handling process
See accompanying drawing 2):
-the first step: judge that signal type is followed the tracks of in outlet, sheared signal in this way, then performed second step；Batch in this way
Complete signal, then perform the 3rd step；Unload volume in this way and complete signal, then perform the 4th step.
-second step: carry out shearing and complete signal processing (setting up coil of strip data record etc.), shearing complement mark is set, table
Show and complete to shear.
Then, it is judged that this shearing completes signal whether analogue signal: analogue signal in this way, then check and batch complement mark
?？If it has not, then analog roll takes into signal as outlet tracking signal, the return execution first step；If any, then flow process
Terminate.
If not being analogue signal, then flow process terminates.
-the three step: judge there is shearing complement mark？
● if any shearing complement mark, then carrying out having batched the process (supplement and batch information etc.) of signal, setting is batched
Complete mark, then judge that this has batched whether signal is analogue signal: analogue signal in this way, then check to unload and rolled up
Become mark？In this way, then flow process terminates；As without and unload volume complete signal arrive be masked as 1 or analogue signal from
HMI, then simulation is unloaded volume signal and followed the tracks of signal as outlet, returns and performs the first step.
● as without shearing complement mark, then simulation shearing completes signal and follows the tracks of signal as outlet, returns execution first
Step.
-the four step: unload volume and complete whether signal is analogue signal, if not, setting is unloaded volume and is completed signal arrival
It is masked as 1.Then judge there is shearing complement mark？
● if any shearing complement mark, then judge to batch complement mark？If any, carry out unloading volume and complete to process (statistics
Calculating etc.), to remove and shear complement mark and batch complement mark, removing is unloaded volume and is completed signal arrival mark, and flow process terminates；
Such as nothing, analog roll takes into signal and follows the tracks of signal as outlet, returns and performs the first step.
● as without shearing complement mark, then simulation shearing completes signal and follows the tracks of signal as outlet, returns and performs the first step.
The described volume standby picture that unloads includes that shearing information input/display box (comprises coil of strip number, volume weight and volume long, wherein coil of strip
Number only can show) and analog buttons, discarded button and cancel button.This picture can be by following the tracks of setting on picture
One start button triggers, it is also possible to triggered by other modes such as shortcuts.
Picture processes as follows:
When this picture is triggered, first check whether shearing complement mark (outlet signal handler is arranged), as
Having, picture input frame display coil of strip length and calculated weight, now operator can not revise data；Such as nothing, picture is defeated
Entering frame and be shown as empty, now operator must input shearing and complete data (coil of strip length and weight).
Pressing [simulation] button, verification is inputted data by picture, and simulation is unloaded volume and completed signal, starts outlet signal processing journey
Sequence.
Pressing [abandoning] button, picture will notify systems abandon online data, not generate coil of strip production data recording.It is suitable for
Could not the in kind situation of output coil of strip because of fault in actual production line.
Press [cancellation] button, do not process, image close.
Above the specific embodiment of the present invention is described.It is to be appreciated that the invention is not limited in
Stating particular implementation, those skilled in the art can make various deformation or amendment within the scope of the claims,
This has no effect on the flesh and blood of the present invention.In the case of not conflicting, in embodiments herein and embodiment
Feature can arbitrarily be mutually combined.
