Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a computer system that inputs and monitors data that changes from time to time on a monitored target such as an electric power system through an information receiving device, and particularly to a monitored target such as an electric power system. The present invention relates to a computer event data file management method for recording and saving event data such as changes in the situation that occur in the event data file, such as a voltage at a monitoring point exceeding a specified value or a change in the opening/closing state of a switch.

[Technical background of the invention]

In general, event data in a power system that is being monitored, for example, refers to changes in binary information such as switches, retention relays, etc., or numerical information such as voltage values, current values, etc. exceeding specified values. .

In order to promptly inform the operator of this information, it is necessary to record and save the information at high speed, output it to a display device, etc. at high speed, and collect a large amount of event data in a short period of time due to accidents such as lightning strikes. It is possible to record and save or output events that occur, to manage event data in chronological order, and to access arbitrary event data in a file at high speed in order to register events such as occurrences and returns. is necessary.

Furthermore, when the event data fills up the file with a limited capacity, it is necessary to access the event data in order to automatically record and print the event data and make the printed event data unnecessary data. The electronic computer is used to register event data.

It is necessary to output, process, and delete data quickly.

Next, an example of a conventional management method for event data will be described with reference to FIGS. 1 and 2. FIG. 1 shows an example of the configuration of a conventional event data file management method in a computer system. In the figure, 1 is an information receiving device for inputting event data into a computer, 2 is a central processing unit (hereinafter referred to as CPU),
3 is a main storage device (hereinafter referred to as main memory).

Further, 4 is a pointer υ for managing the event data file in the main memory 3, and 4a is a TOP record indicating the beginning position of the event data in the recorded file.
4b is an END record indicating the final position of event data in the recorded file; 4c is the amount of event data held;
4d is the file capacity set to a predetermined value, 4e is the output target specified amount to which a predetermined value is set, 4f is the output specified amount to which a predetermined value is set, and the held amount of event data 4c is Output target specified amount 4e
When the specified output amount 4f is reached, the event data is printed on a recording device to be described later, and the event data is left as a record, and the printed event data is used as unnecessary data to free up space in the event data file 6, which will be described later. This information is used to enable the registration of subsequent event data. On the other hand, 5 is an auxiliary storage device (hereinafter referred to as bulk memory), and 6 is a bulk memory 5. By updating the above TOP record 4a and END record 4b, event data is cyclically stored in chronological order. 7 is a display device, and 8 is a recording device.

Next, such an operation will be described using the flowchart shown in FIG.

First, in step SII of FIG.
It is registered at the position in the event data file 6 indicated by b, the END record 4b in the pointer 4 is logically advanced by 1, and the held event data amount 4c is increased by 1.

Next, in step S13, if the data retention amount 4c in the -inter 4 exceeds the output target specified amount 4e, the process goes to step S14, and if it does not, the process goes to step fS15. In step s14, from the event data at the position in the event data file 6 indicated by the TOP record 4a in the pointer 4, the specified output amount 4f is sequentially transferred to the main memory 3 one by one, and automatically printed in the recording device 8. perform the output,
The old event data is deleted as unnecessary data by logically incrementing the TOP record 4a in the pointer 4 by 1 and decrementing the data retention amount 4c by 1. In step fs15, new event data is processed according to predetermined rules, and in step fs15, the event data is displayed and output on display device 7 in step 7''816.

[Problems with background technology]

However, the conventional method described above has the following disadvantages. In other words, each processing step in the flowchart in Fig. 2 shows a series of cumulative flows, and in reality, each processing step is processed in parallel, and when multiple events occur at the same time, event data is registered, Because the output, processing, and deletion processes overlap, the input/output of the event data file 6 due to each process is infrequent, and the event data file 6 has a ring-shaped configuration, it is difficult to register and delete the event data 6. ) There is no other choice but to perform the transfer one by one, which increases the number of transfers between the main memory 3 and the bulk memory 5.

This causes a lot of waiting for the use of the event data file 6, which slows down the processing speed. In particular, in large-scale systems, there is a strong desire to improve the services of man-machine interfaces to prevent synergistic processing delays due to addition of functions and increase in processing volume.

Therefore, as a way to solve these inconveniences, it is possible to place the event data file 6 on the main memory 3.
If the amount of data is large, a large main memory 3 is required, so it cannot be stored on the main memory 3.

[Object of the invention].

The present invention has been made in view of the above circumstances, and its purpose is to enable event data to be retrieved all at once in chronological order when it is desired to refer to the event data of a number at once, and to print the event data. Computer event data that can dramatically reduce the number of transfers for each function by eliminating the various processes that were performed when the computer is running, reduce waiting time for use, speed up the processing speed, and improve the service of the man-machine interface. Its purpose is to provide a method for managing files.

[Summary of the invention]

In order to achieve the above object, the present invention is characterized in that pointers and file configurations are divided into monitoring and recording, and event data is transferred all at once in processing in each function.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 3 shows an example of the configuration of the computer event data file management method according to the present invention. The same parts as in FIG. I will only talk about.

In the figure, 9 is a pointer for managing the event data file in the main memory 3), and 9a indicates the starting position of the event data group for recording only old event data that needs to be printed out. 9b is the amount of recording event data held indicating the amount of the recording event data group, and 9c is the start position of the monitoring event data group that leaves only the data that needs to be monitored among the event data. 9d is the amount of monitoring event data held indicating the amount of the above monitoring event data group, 9e is the file capacity with a predetermined value set, 9f
is the output target specified amount with a predetermined speed,
9g is a specified output amount set to a predetermined value. In addition, 10 is an event data file, which does not have the conventional ring-shaped configuration and is used to record only the old event data that needs to be printed out among the event data, and to monitor among the event data. This is an event data file with a sequential structure in which the file is divided into a monitoring event data group that leaves only necessary data.

Next, the operation of the present invention will be described using the flowchart shown in FIG.

Now, for example, when the state of binary information of switches, protection relays, etc. changes in the power system as a monitoring target, event data is input to the information receiving device 1 in step 811, and the input event data is input in step 812. is registered in the monitoring event data record in the event data file 10 indicated by the record obtained by adding the monitoring TOP record 9c in the pointer 9 and the monitoring data holding amount 9d, and Data holding amount 9d
Increase by 1.

Next, in step 813, if the monitoring event data retention amount 9d in the pointer 9 exceeds the output target specified amount 9f, the process proceeds to step S17; if it does not exceed the output target specified amount 9f, step S1
5 respectively.

In the Stella fs17, the amount of retained monitoring event data 9d is calculated from the position indicated by the monitoring TOP record 9C in the pointer 9.
The retained data shown in is transferred to the main memory 3 all at once, the attributes of each event data are evaluated, and the data is divided into two for monitoring and recording, and then transferred to the event data file 10. In addition, the new holding amount 9b, depending on the amount of each distributed data,
9 (by creating 1 and writing to pointer 9,
The recording event data of the printing cylinder that was previously contained will be automatically deleted at this time.

Therefore, the process of deleting unnecessary data at the time of printout, which was conventionally performed one by one, is no longer necessary.

In step 818, the record printing task prints the data held in the event data file 10 from the position shown by the recording TδP record 9a in the pointer 9 newly created in step S17. data from the event data area and pointer 9.
Automatically prints out without any processing. Here, by using a recording event data area exclusively for printing, printing processing can avoid overlapping processing with monitoring processing, and both processes can be performed quickly.

In step 815, the monitoring task collectively transfers the data held by the monitoring event data holding amount 9d from the position shown by the monitoring TOP record 9c in the pointer 9, and according to predetermined rules such as time elapsed management and event record exchange. According to the evaluation etc., the event data file lo
All data are transferred to the monitoring event data area within the event data area.

Therefore, by making batch transfer possible, processing speed is improved.

Furthermore, in step 816, the plurality of monitoring event data processed in step 815 are displayed on the display device 7 by one transfer. As a result, the processing speed is improved by requiring only one transfer compared to the conventional multiple transfers.

As described above, the information receiving device 1. CPU2゜Main memory3. It is composed of a bulk memory 51, a display device 7, and a recording device 8, and it inputs event data that changes from time to time in a monitoring target such as an electric power system, records and stores it in an event data file 1θ, and displays the display device 7. A method for managing an event data file 10 of a computer system that is output to a recording device 8 includes means for inputting the event data from the information receiving device 1, and means for recording and storing the input event data in chronological order. and a means for sorting the recorded and saved event data into monitoring and recording purposes respectively and deleting unnecessary data, and a means for deleting unnecessary data by sorting the recorded event data into the recording device 8 in a specified amount. It is composed of means for automatically printing out, means for processing the monitoring event data according to predetermined rules, and means for displaying and outputting the processed monitoring event data on the display device 2.

Therefore, according to the management method of the present invention, when you want to refer to multiple event data by clicking the button, you can retrieve the event data one by one, instead of retrieving the data one by one, in chronological order. By making it possible to take out data all at once, and by discontinuing the various processes that were conventionally performed when printing event data, the number of transfers for each function is drastically reduced, reducing the waiting time for use, and increasing the processing speed. It is possible to improve the service of man-machine interface.
