First judge module 300, is used for judging that actual roll shifting parameter is whether within threshold range；Enter
One step, the first judge module 300, including:
First data transmission unit 310, for being transferred to the actual roll shifting parameter inputted in slave computer
Host computer；
First judges performance element 320, in host computer, it is judged that whether actual roll shifting parameter exists
Within threshold range；
First errored response module 400, is not exist for the judged result at the first judge module 300
In the case of, display input is invalid or is set to setting value, and sends alarm.Further, the first mistake
Respond module 400, including:
Second data transmission unit 410, for judging that first the judged result of performance element 320 is
The most in case, input invalid information or setting value are transferred to slave computer；
First errored response performance element 420, for after the second data transmission unit 410, connects
Breath display input of collecting mail is invalid or is set to setting value, and sends alarm.
This device inventive embodiments more specifically technical scheme also includes:

Second judge module, specifically for after slave computer receives errorless confirmation, it is judged that with reality
Whether slab corresponding to border roll shifting parameter is finish rolling slab.
In the present embodiment, host computer is finish rolling platform, and slave computer is HMI(Human Machine
Interface, man machine interface).
It should be noted that the finish rolling platform in the present invention is shared interior by memory mapping net with HMI
The form deposited realizes communication, and this communication modes is higher than the Realtime Capability of Communication of ICP/IP protocol, surely
Qualitative higher.Its communication modes is as shown in Figure 2:
1. by the title of CIMPLICITY software definition offset address amount, corresponding HMI in HMI
The mode of variable, the address of corresponding memory mapping net and read and write (i.e. some offset address amount be for
Reading data, some offset address amount is for writing data)；
2. go out defined in finish rolling platform one section on all four with the address of core image net in HMI share
Internal memory, mark off the region of read and write (i.e. some region is for reading data, and some region is simultaneously
For writing data)；
3. cycle roll shifting initial position, cycle roll shifting lower limit, week are set in the shared drive of finish rolling platform
The phase roll shifting upper limit and cycle roll shifting frequency；
4. when operative employee inputs actual roll shifting parameter on HMI, i.e. variable in HMI changes,
CIMPLICITY software writes core image net by offset address amount, is transferred to sharing of finish rolling platform
Internal memory；Such as: the scope of " cycle roll shifting initial position " is set to [0,150], " cycle roll shifting
Lower limit " scope be set to [-150,0), the scope of " the cycle roll shifting upper limit " be set to (0,150],
" cycle roll shifting frequency " is set to 2, and clicks on " confirmation " button, the roll shifting that the most just will arrange
Parameter is transferred in the shared drive of finish rolling platform.
5. after finish rolling platform carries out judgement process to the data in shared drive, more corresponding data are passed
It is passed in the core image net of HMI；
6.CIMPLICITY software detection changes to the memory mapping network data of HMI, reads data
And update HMI, complete the setting to cycle roll shifting parameter.
It should be noted that after each roll change, operator can as required in HMI more
Change cycle roll shifting bound, initial position and the frequency of next roller phase.After amendment, click on really
Recognize, final cycle roll shifting bound, initial position and frequency can be shown in the place of input numerical value
Rate.When finding that certain numerical value is not the numerical value of oneself input just now, and show input invalid information or pre-
If during value, that must be input value beyond the roll shifting parameter area preset in finish rolling platform, at this moment
Relative alarm information can be checked in alert box, thus select again input or use default value.
The roll shifting control method for hot rolling operation of embodiment of the present invention offer and device, first arrange roll shifting
The threshold range of parameter；Judge that the actual roll shifting parameter of input is whether within threshold range again；If not existing,
Then show that input is invalid or is set to setting value, and send alarm, so that operator understand altering of input
Roller parameter error, and carry out corresponding treatment measures, and then maintain being normally carried out of production.The present invention
By the improvement of program makes operator can need not notify two grades of engineers' according to producing needs
In the case of, the relevant roll shifting parameter of amendment in HMI, not only increases production security, increases the most at any time
Add the control ability to plate shape；And save the production time, improve rhythm of production.The present invention is real
Execute example and also there is feature efficient, stable and real-time.
It should be noted last that, above detailed description of the invention is only in order to illustrate technical scheme
And unrestricted, although the present invention being described in detail with reference to example, the ordinary skill people of this area
Member should be appreciated that and can modify technical scheme or equivalent, without deviating from
The spirit and scope of technical solution of the present invention, it all should be contained in the middle of scope of the presently claimed invention.
