Abstract

PURPOSE:To make a high-precision simulation possible with an easy operation without preparing troublesome data for operation, by using data of actual rolling for tracking simulation. CONSTITUTION:Actual data of the timing of the event occurrence is taken into an input device 10 at the time point of the tracking start in actual rolling and is stored in a tracking file 5 or a flexible disc 11. This data is used as a rolling simulation signal in off-line. Consequently, the simulation is performed in the on-line state. Preparations on the desk before the execution of simulation are unnecessary, and the rolling pitch is changed variously. The disc 11 is used for preservation of simulation data mainly, and data of the disc 11 can be returned to the tracking file 5 when simulation is executed again.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tracking simulation in a hot rolling system for iron, for example.

FIG. 1 is a block diagram showing an example of a conventional rolling simulation signal generator. In the figure, (1) is a punch card reader for inputting data, (2) is a tracking simulator, (3) is a CRT for monitoring, (4) is a line printer for logging, and (5) is a file for tracking. When performing tracking simulation in the rolling simulation signal generator configured as above, KFi,)
It was necessary to prepare rolling data used by the racking simulator (2) during simulation, events occurring on the process side, etc. before the simulation. In such cases, simulation data is usually input by reading a data card punched in a predetermined format from a punch card reader (1). The tracking simulator (2) stores this data in a tracking file (5)K, and when the tracking simulator (2) is started, it retrieves the data necessary for simulation from this tracking file (5) and calculates the simulation results. CRT for monitoring (3)
and displayed on a logging line printer (4).

However, in order to perform a sufficient simulation, it is necessary to prepare a large amount of simulation data in the form of a large number of cards, so it is necessary to perform error processing to eliminate punch errors, etc., and if the error processing is simplified, it will be necessary to prepare a large number of cards for the simulation. This method has the disadvantage that the possibilities for simulation must be increased or the simulation patterns must be limited.

The object of the present invention is to provide a rolling simulation signal generator that can simulate conditions close to actual rolling with fewer simulation errors.

FIG. 2 is a block diagram showing one embodiment of this invention! 7% (2) to (5) indicate the same or equivalent parts as the same reference numerals in FIG. 1 above. In the figure, the head is a data input device that inputs events and performance data from the process side, and the alpha power is a flexible disk that stores data from this input device. - In the rolling simulation signal generator configured as described above, first, the actual data from the time of tracking start to the timing of the occurrence of the event during actual rolling is taken in from the data input device (11) and sent to the tracking file ( 5) Or flexible disk O
Store it in power. The event here means a group of events during actual rolling, such as an event from the process side and the timing of starting an application inside the computer. Regarding performance data, it means both the input from the tun process side and the output processed inside the computer and used for setting on the process side.

The actual data during actual rolling described above is reproduced and used as a rolling simulation signal when offline. Therefore, in an offline state, simulations that could not be obtained using conventional simulation methods can be performed. In addition, no preparation on the desk is required before carrying out the simulation, and the rolling pitch can be varied in various ways.

As mentioned above, the flexible disk α force is mainly used to store simulation data.
The data can be returned to the tracking file (5) when the simulation is executed again.

Furthermore, this rolling simulation signal generator can be modified and added to the application software in response to maintenance and expansion of the rolling equipment. In such a case, it is necessary to perform sufficient debugging and testing offline rather than reproducing a situation close to the online state and performing a software and hardware heat run.

If this device is used, simulations can be performed based on the actual data collected at various rolling pitches. Therefore, it is possible to test the operation of the application software in advance.1. Online driving times can be predicted more accurately. In addition to checking the computer's tracking function, it is also possible to predict the CPU load upon expansion, allowing smooth online operation.

As explained above, the tracking system uses data from the actual rolling process for unilateral rolling, so there is no need to prepare troublesome data during operation, and it is possible to perform highly accurate simulations with simple operation. Scale - has the effect of having a significant effect on the system.
