Abstract

PURPOSE:To eliminate a waste of the operation of the computer of the blast furnace computation system by determining previously data to be gathered corresponding to a process state by using a mask pattern and a check pattern and gathering the data. CONSTITUTION:A computer 2 refers to a data file 3 by using the mask pattern and check pattern which are supplied through a process I/O1 and corresponds to the process state. Then, the computer determine data which needs to be gathered on gathering condition among data, etc., to be gathered on the basis of the determined and specified gathering numbers of a gathering group. The data from a blast furnace are gathered on the basis of said data and stored in the data file, and only the data which needs to be gathered are gathered, thereby eliminating a waste of the operation of the computer.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a computer system for managing and controlling a blast furnace process, and particularly relates to a method for collecting process data.

[Background of the invention]

The blast furnace process management control computer system collects a large amount of data as blast furnace process data, but it is not always necessary to collect all the data, and there is a considerable amount of data that cannot be collected unless conditions are met. When performing this processing on software, conventionally, as shown in the flowchart in Figure 1, all data is first collected, and then various conditions are determined and data that no longer needs to be collected is treated as missing values. I was trying to replace it. In this method, the computer always collects all data, which results in unnecessary input/output operations, which results in the computer using a lot of processing time.

Furthermore, since the determination of data that does not need to be collected is made after all data has been collected, there is a drawback that a memory area is required to store all the data once.

[Purpose of the invention]

The purpose of the present invention is to distinguish between data that needs to be collected and data that does not need to be collected before starting collection, and then collect only the data that needs to be collected.
The purpose of the present invention is to provide a method for eliminating unnecessary operations as a computer.

[Summary of the invention]

The main point of the present invention is that when collecting process data, it is possible to determine the data to be collected from the external situation, and by taking in the external situation as a process signal, the combination conditions of these signals are created in a table, and the conditions can be changed or added. It's easy to do.

[Embodiments of the invention]

Embodiments of the present invention will be explained with reference to FIGS. 2 to 5.

In FIG. 2, data of the blast furnace process is taken into a computer 2 via a process input/output device 1. In the computer 2, the data collection condition table is read from the data file 3, and the collected data is stored in the data file 4.

FIG. 3 shows a flowchart of the method for determining collected data according to the present invention. At A in the figure, a process status signal is taken in via the process input/output device 1.

This captured signal is shown at 5 in FIG.

In the processes B to D in FIG. 3, sampling conditions are determined using the captured signal state 5 and the patterns shown by 6 and 7 in FIG. In this example, the sampling conditions are classified into five groups A to E.

First, the signal 5 and the mask pattern 6 are ANDed, and it is checked whether the result matches the check pattern 7 or not. In this example, C is excluded from collection groups A to E. <A, B
, D, and E will match, which is the case in the operating state indicated by signal 5.

It is shown that four groups A, B, D, and E satisfy the collection conditions. In this manner, when the conditions are satisfied as a collection group, the collection target logical number table 8 in FIG. 5 is taken out and the logical sum is calculated. The logical number is a consistent number assigned to data collected from a process.

The results obtained by calculating the logical sum of the logical numbers to be collected in the groups that can be collected are shown in FIG. 5 and 9 in FIG.

Result 9 expresses the logic NO that should be collected under the operating state given by signal 5 as 1, and the logic N that does not require collection.

is indicated by 0.

This method determines the data to be collected under given conditions. From then on, it is only necessary to collect data for the determined logic-UO. [Effects of the Invention] According to the present invention, new data collection can be easily added and data collection can be canceled, and the collection conditions can be adjusted. It can also be easily changed.
