Hereinafter, the control method is illustrated.
As shown in figure 4, control device 200 performs rate-determining steps (step S1).That is, step enforcement division 211 is determined with reference to step
Adopted portion 210, performance objective value calculation procedure 221 (initial step).
Then, control device 200 is confirmed whether to obtain halt instruction (step S2) by halt instruction acquisition unit 232.
In the case of no acquisition halt instruction, control device 200 is confirmed whether that (step can be shifted to next rate-determining steps
S3).For example, it is confirmed whether to complete the calculating of the desired value in target value calculating step 221.The calculating of desired value is not being completed
In the case of (in the case of next rate-determining steps can not be transferred to), control sequence is back to step S2 by control device 200.
In the case of completing the calculating of desired value (in the case of being transferred to next rate-determining steps), control device 200 will be controlled
System order is back to step S1, and performs weighing stage 222 (next rate-determining steps).
In the step S3 after performing weighing stage 222, control device 200 for example confirms to cut from storage hopper 31
To the weight (hereinafter referred to as " cutting quantity " of the raw material of weigh hopper 33.) whether reach desired value of weighing.It is not up in cutting quantity
In the case of desired value of weighing (in the case of can not being transferred to next rate-determining steps), control device 200 returns control sequence
It is back to step S2.In the case where cutting quantity reaches desired value of weighing (in the case of next rate-determining steps can be transferred to),
Control sequence is back to step S1 by control device 200, and performs discharge step 223 (next rate-determining steps).
In the step S3 for performing discharge step 223, control device 200 is for example confirmed whether to complete to come from weigh hopper
The discharge of 33 raw material.In the case where not completing the discharge of raw material (in the case of next rate-determining steps can not be transferred to),
Control device 200 makes control sequence be back to step S2.(it can be transferred to next in the case where completing the discharge of raw material
In the case of rate-determining steps), control device 200 makes control sequence be back to step S1, and performance objective value calculation procedure again
221 (next rate-determining steps).
Afterwards, untill confirming to obtain halt instruction in step s 2, control device 200 is based on bar set in advance
Part, rate-determining steps 221~223 are repeatedly performed successively.In addition, control device 200 performs according to multiple actual control objects 30
Rate-determining steps 221~223.That is, the control method performed by control device 200 can control multiple actual control objects 30.
If confirming to obtain halt instruction in step s 2, control device 200 stops performing rate-determining steps so that weighing
Process stops, and shows and stop step (step S4).That is, halt instruction acquisition unit 232 makes to be performed by step enforcement division 211
Rate-determining steps stop, stopping step display part 233 according to each actual control object 30, will stop step being included in console
On 113.
Then, control device 200 is confirmed whether to require that acquisition unit 234 starts again at instruction to obtain by starting again at
(step S5).Do not got within specified time limit in the case of starting again at instruction, control device 200 completes control sequence.Can
Suitably to set specified time limit.
Got within above-mentioned specified time limit in the case of starting again at instruction, control device 200 is according to each reality
Control object 30 obtains the rate-determining steps (step S6) for starting again at object.That is, step acquisition unit 235 is started again at according to each
Actual control object 30, the rate-determining steps for starting again at object are obtained from console 113.
Then, the control object in rate-determining steps is switched to simulator 300 (step S7) by control device 200.That is, control
Object switching part 231 is after the process weighed stops and before execution initial step, by the control of step enforcement division 211
Object switches to simulator 300.
Then, control device 200 makes rate-determining steps be transferred to initial step, and eliminates the data (step before stopping
S8).That is, the rate-determining steps when process that initialization section 236 makes to weigh stops are transferred to initial step, and eliminate and be stored in
Data of the control before the stopping in memory 213.
Then, control device 200 starts again at execution rate-determining steps, and performs according to each actual control object 30 following
Control sequence.Control device 200 performs initial step (step S9, S12, S15), confirms after the execution of initial step is completed
Whether next step is to start again at step (step S10, S13, S16).That is, step enforcement division 211 defines portion with reference to step
210 perform initial step.Whether the rate-determining steps that stepping limiting unit 237 confirms then to be performed by step enforcement division 211 are again
Secondary beginning step.Next rate-determining steps are not that control device 200 is back to control sequence in the case of starting again at step
Step S9, S12, S15, and perform next rate-determining steps.Thus, perform successively from initial step to starting again at object
Previous rate-determining steps.
In the case that next rate-determining steps is start again at step, control device 200 is limited to next rate-determining steps
Transfer (step S11, S14, S17).That is, stepping limiting unit 237 limits the rate-determining steps performed by step enforcement division 211 and shifted
To next rate-determining steps.Thus, carry out to from the previous rate-determining steps of object are started again to the control for starting again at object
The stepping limitation that the transfer of step processed is limited.
Control device 200, will after the rate-determining steps of all actual control objects 30 have been carried out with stepping limitation
Control object in rate-determining steps switches to actual control object 30 (step S18).That is, control object switching part 231 is again
Start object previous rate-determining steps be performed after and start again at the rate-determining steps of object and be performed before, will control
Control object in step switches to actual control object 30.As shown in step S7 and step S18, performed by control device 200
Control method include：Using simulator 300, the control object in rate-determining steps is switched into actual control object 30 or simulation
Device 300.
Then, control device 200 releases stepping limitation (step to the rate-determining steps of all actual control objects 30
S19), and control sequence is made to be back to step S1.That is, control object switching part 231 is by the control object of step enforcement division 211
It is switched to after actual control object 30, restriction cancellation portion 238 releases the limitation carried out by stepping limiting unit 237.Afterwards, control
Device 200 performs above-mentioned control sequence repeatedly.Furthermore it is possible to suitably change step S1~S19 order.For example, also may be used
With exchonge step S6~S8 order.
As described above, iron-smelting device 1 possesses actual control object 30, simulator 300 and control device 200.Control
Device 200 processed performs following control：Multiple rate-determining steps are performed based on condition set in advance successively；By the control in rate-determining steps
Object processed switches to actual control object 30 or simulator 300.Therefore, by the way that the control object operated after starting again at is made
For virtual controlling object, control object is switched into actual control object in midway, without reverse execution or omits control
Step, it becomes possible to start again at the control to actual control object from arbitrary rate-determining steps.Assuming that make the reality that midway stops
, it is necessary to make actual control object be back in itself just in the case that control object re-executes rate-determining steps since initial step
Beginning state.On the other hand, due to the control to actual control object can be started again at from arbitrary rate-determining steps, therefore need not make
Actual control object is back to original state in itself, can promptly start again at the control to actual control object.Accordingly, it is capable to
Enough suppress the reduction of reliability, and can promptly start again at rate-determining steps.
Control device 200 further performs：Obtain the rate-determining steps for starting again at object；The process of ironmaking is stopped
Rate-determining steps when only are transferred to initial step, and after the process of ironmaking stops and before execution initial step, control
Control object in rate-determining steps is switched to simulator 300 by device 200 processed, is performing the previous control that starts again at object
After step processed and before performing the rate-determining steps for starting again at object, control device 200 is by the control object in rate-determining steps
Switch to actual control object 30.Therefore, it is possible to which after the rate-determining steps for needing to perform again are determined, the rate-determining steps are set
It is set to and starts again at object.By making rate-determining steps be back to initial step, execution rate-determining steps can be reliably started again at.
By the way that control object is switched into the void before rate-determining steps are transferred to after initial step and perform the rate-determining steps
Intend control object, execution rate-determining steps can be just started again at without the actual control object of movement.By performing again
Control object is switched after the secondary previous rate-determining steps for starting object and before performing the rate-determining steps for starting again at object
For actual control object, rate-determining steps after object step are started again at so as to be performed for actual control object.Cause
This, can more reliably realize the control for being started again at from the rate-determining steps for needing to perform again and performing actual control object.
The control of rate-determining steps when the process that control device 200 further performs display ironmaking stops.Thus, operate
Member is easy to confirm to stop step, therefore, it is possible to promptly determine to need the rate-determining steps performed again.Therefore, it is possible to more quickly
Start again at execution rate-determining steps.
Iron-smelting device 1 possesses multiple actual control objects 30.Control device 200 is further performed to from starting again at object
Previous rate-determining steps shift the stepping that is limited to the rate-determining steps for starting again at object and limit and release stepping limit
System, and the rate-determining steps of all actual control objects 30 have been carried out after stepping limits, by the control in rate-determining steps
Object processed switches to actual control object 30, and by the control object in rate-determining steps be switched to actual control object 30 it
Stepping limitation is released afterwards.Therefore, by synchronously starting again at the rate-determining steps for multiple actual control objects 30, Neng Gouti
High reliability.
Simulator 300 is built in control device 200.Therefore, it is possible to suppress the maximization of control system 100.
More than, embodiment is illustrated, but the invention is not restricted to above-mentioned embodiment, do not departing from its purport
In the range of can carry out various changes.Such as simulator 300 can not be built in control device 200.Control system
