Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an arithmetic processing device, and particularly to an arithmetic processing device suitable for use as an arithmetic processing device in an online real-time computer system.

[Conventional technology]

Conventionally, when image processing is performed using a computer system,
As described in Japanese Unexamined Patent Publication No. 62-25378, two CPUs are prepared as arithmetic processing units, and each CPU divides the search and transmission of one image data, thereby increasing the response speed. things are being done. According to this method, each CPU processes according to the processing item, so
It is possible to speed up arithmetic processing even when there is a high load with a large number of processing items.

[Problem to be solved by the invention]

However, in the conventional technology, the system is designed assuming maximum load, so even under high load when there is a large number of processes to automatically update the screen displayed on the CRT screen, it is possible to update the screen within a certain amount of time. It is possible to perform calculation processing on the computer, but even when the load is relatively low, such as when only some terminals require processing to automatically update the screen, it must be performed at the same processing time interval as when the load is high. However, it was not sufficient to perform calculation processing efficiently. In other words, when the number of cases to be processed is small, the processing time interval is made as short as possible,
More detailed processing is required.

An object of the present invention is to provide an arithmetic processing device that can process the contents of items to be processed in a processing time that corresponds to the number of items to be processed.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a processing number calculation means for calculating the number of items to be processed within a certain processing time based on an execution command, and a processing number calculation means. A processing time setting means for setting a processing time to increase the processing time interval according to an increase in the number of processing cases when a calculation result of a plurality of processing cases is obtained from the output of the means; The present invention constitutes an arithmetic processing device having processing means for sequentially processing the contents of each item to be processed according to the processing time.

Furthermore, in addition to the above-mentioned apparatus, an arithmetic processing device is constructed which includes a processing time display means for displaying a processing time interval set by the processing time setting means.

[Effect]

The number of items to be processed within a certain processing time is calculated based on the execution command, and if the number of items to be processed is multiple,
Set the processing time to increase the processing time interval as the number of processing cases increases. That is, when the number of processing cases is large, the processing time is set to be longer than when the number of processing cases is small. Then, the contents of each item to be processed are sequentially processed according to the set processing time. Additionally, display the processing time interval.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG.

In FIG. 1, various data from the operation of a controlled plant 10 are input to an arithmetic processing device via a data collection device 12. The arithmetic processing unit is data collection processing circuit 1
4. Data file 16, timer 18, time interval determination circuit 20. Timer 22, execution command processing circuit 24, screen editing display circuit 26, timer 28. It is composed of a set value output circuit 30, a data collection processing circuit 14 is connected to the data collection input device 12, and an execution command processing circuit 24 is connected to keyboards 32A, 32B, 32C, 32D, and 32E, respectively, for one-screen editing display. The circuit 26 is CRT34A, 3
4B, 34G, 34D, and 34E, respectively, and the set value output circuit 30 is connected to the controllers 36A, 36B, and 36.
C, 36D, and 36E, respectively. The output of each controller 36A to 36E is the controlled plant 1o.
It is output to the controlled plant 10 as an operation command value.

The data collection processing circuit 14 is configured to take in performance data of the controlled plant 10 from the data collection input device 12 in accordance with activation of the timer 18, and sequentially transfer the input data to the data file 16.

The execution command processing circuit 24 is configured as processing number calculation means for calculating the number of items to be processed within a certain processing time based on execution commands from the keyboards 32A to 32E. That is, the number of data collection points from the keyboards 32A to 32E, the number of CRTs to be automatically updated, and the CRs to display images.
It receives an execution command such as a designation of T and a command to designate a controller among the controllers 36A to 36E that should output a setting value, and calculates the number of items to be processed within a certain processing time based on this execution command. The result is output to the time interval determining circuit 20. The time interval determination circuit 20 is configured as a processing time setting means, and inputs the calculation results from the execution command processing circuit 24, and when the calculation results for a plurality of processing cases are obtained, the processing is performed according to the increase in the number of processing cases. Set the processing time to increase the time interval, and use the timer 18 according to this setting value.
゜22.28. It is designed to start. This processing time interval is determined by the following equation (1).

T=a-n+b...(1) Here, a: a constant, n: the number of processed cases, and b two constants.

The time interval is set to 1, for example, when the number of screens to be automatically updated is large, the update time interval is set to be large, and when the number of screens to be automatically updated is small, the update time interval is set to be small. Further, when the number of data points to be collected is large, the data collection time interval is set to be large, and when the number of data collection points is small, the data collection time interval is set to be short. Also, when the number of set value outputs to the controller is large, the time interval between set value outputs is set to be large, and when the number of set value outputs is small, the time interval between set value outputs is set to be short. Further, when setting this time interval, the number of processing items is determined based on the minimum processing time that can be processed within a certain processing time.

The screen editing display circuit 26 edits an image related to the operation of the controlled plant 10 based on the actual data stored in the data file 16 when receiving an execution command or when automatically updated, and sends the edited image signal to the CRTs 34A to 34E. It is designed to be output. Each CRT has a 6 set value output circuit 3 which displays an image of performance data on the screen in response to an image signal from a screen editing display circuit 26.
0 generates set values for the controlled plant 10 based on the performance data stored in the data file 16, and outputs the generated set values to each of the controllers 36A to 36E.

As described above, in this embodiment, the time interval for data collection is determined by the activation time of the timer 18, the time interval for automatic screen updating is determined by the activation time of the timer 22, and the time interval for outputting the set value is determined by the activation time of the timer 22. The interval is set by the activation time of the timer 28. The data collection processing circuit 14 serves as a processing means for collecting data, the screen editing display circuit 26 serves as a processing means for editing and displaying a screen, and the setting value output circuit 30 outputs setting values. They are each configured as a processing means for.

Also, the number of CRTs is 10, constant a = 0.5, constant b
If =o, timer 22 for automatically updating one screen
The processing time interval is 5 seconds. And the number of CRTs is 2
When the number increases to 0, the activation time interval of the timer 22 is 1.
It becomes 0 seconds. As a result, editing and display processing for 10 CRTs is performed at 5 second intervals, and editing and display processing for 20 CRTs is performed at 10 second intervals. In this case, the processing amount per unit time of calculation processing time is the same.

In addition, the screen editing display circuit 26 performs an editing display process for displaying the performance data as an image by starting the timer 22, and
It is configured to display each processing time interval determined by the time interval determining circuit 20 on the screens of the CRTs 34A to 34F. In this case, the keyboards 32A to 32
Since the operator operating E can be informed of the current processing time interval, it is possible to prevent operational delays that would otherwise occur if the processing time intervals are different.

According to this embodiment, the number of data collection points, the number of CRTs whose screens should be automatically updated, and the number of controllers that should output set values change from moment to moment depending on the operating conditions of the plant 10. However, since each processing time interval can be changed according to this change, it is possible to efficiently operate the plant IO.

Furthermore, according to the above embodiment, in order to address the constraints on the demonstration functions of the software due to the limitations of processing power, which is an issue at the time of designing a computer system, the functions of the software are changed in response to the ever-changing environmental conditions, and the environment is improved. The maximum capacity of the system can always be provided even under low conditions, and hardware resources can be utilized efficiently, and it can contribute to improving the cost performance of the computer system.

Still further, according to the embodiment, tracking.

It is also possible to prevent delays in responses such as information processing, regardless of the processing amount of the computer system.
