Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a data-driven scheduling system, and in particular, by simply loading a data medium such as a floppy disk into a corresponding peripheral device, the data This relates to a data-driven scheduling method that automatically starts a job that reads data contained in a file and processes it.

(Prior Art) Conventionally, a recording medium on which a so-called job control language (JCL, including accompanying data, if any) is recorded as a job input stream is loaded into an input peripheral device. Some OS (operating systems) use a method that starts reading the contents of this recording medium using the attention interrupt that occurs when it becomes ready, and automatically starts the job that has been read. It has been adopted.

However, for example, when a user finishes a day's work and obtains a data medium that records only data related to that work, a processing program that processes this data medium simply by loading it into a corresponding peripheral device. A method of automatically starting a job is generally not used.

As a result, each time a processing request is made for a data medium containing only such data, the user must, for example, start a processing program (job) to process the data under control from the console, or
Alternatively, it is necessary to inject some form of job control language into the system to start this job, so that it can process the data medium described above. For this reason, there is a drawback in that a data medium containing only data cannot be handled unless a person knows how to perform such operations.

In particular, in the case of card readers and paper tape readers, whether or not data has been read from the medium can be easily determined by the movement of the medium, whereas in the case of floppy disk devices, the content of the medium can be easily determined. It is impossible to know whether or not the information has been read by the system without seeing the message from the system, making it even more difficult for beginners and amateurs to use it.

(Object of the Invention) The object of the present invention is to eliminate the above-mentioned drawbacks, and to enable anyone who has an interest in the data to be processed, even beginners and amateurs who have no specialized knowledge of data processing operations on general-purpose computers, to The object of the present invention is to provide an operating environment that allows a corresponding computer to easily process the data.

(Structure of the Invention) The method of the present invention includes a trigger means that uses an attention interrupt generated by loading a data medium in a peripheral device and setting it in a ready state as a trigger for starting data reading from the data medium. , a data reading means for starting automatic reading from a data medium loaded in the peripheral device in response to the activation trigger and thereby creating a data file; an identification means for identifying that the file contains only the data; and based on the identification result, a processing program that is registered in advance in the system disk to process this file is specified, and the specified processing program is used to process the file. A starting means for automatically starting the file as an input file, and a lock release command issued based on the completion of the creation of the data file and the identification result, the medium is pushed out from the normal loading device and the input of data on the medium is completed. This includes a floppy disk device that has a function that allows it to be distinguished.

(Example) Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of one embodiment of the present invention.

This embodiment is an information processing system consisting of a central processing unit 1 and a plurality of peripheral devices 2-1, 2-2, . . . 2-K.

This central processing unit 1 includes, in addition to the CPU main body, a main memory device and an input/output control device (none of which are shown).
etc. shall be included.

Further, in this embodiment, the plurality of peripheral devices 2-1 to 2-K include a floppy disk device 2-1, a card reader 2-2, a paper tape reader 2-3, and a disk device 2-K. .

Furthermore, the floppy disk device 2 of this embodiment
As shown in FIG.
By loading the floppy disk medium 20 and pushing it into the correct position, the locking mechanism 22 locks the floppy disk medium 20 in that position, and the loading detection mechanism 21 detects that the floppy disk medium 20 is locked in the correct position. It detects this and generates a loading detection signal. This loading detection signal is ANDed with a signal indicating that there is no abnormality in other parts of the floppy disk device 2-1 and normal operation is possible, and this is processed as a data signal 2000 by the central processing unit. 1 and is used as an attention interrupt to the OS.

Furthermore, this floppy disk device 2-1
When receiving the lock release signal 1000 from the central processing unit 1, it releases the lock on the floppy disk medium 20 of the locking mechanism 22, and as a result, the disk medium 20 is moved from the correct loading position by the action of the pushing mechanism 23. Extruded. This allows the operator to clearly determine that the necessary processing for this floppy disk medium 20 has been completed.

Now, in this embodiment, the operation when a floppy disk medium containing only data to be processed is provided will be described below.

As mentioned above, the data on this floppy disk medium includes, for example, raw data in which a certain user records only the data related to the work obtained during the day at the end of the day's work in the order in which it was input, and that data. The name of the file registered in advance in the system shall be included.

The operator first loads the floppy disk medium 20 into the floppy disk device 2-1, pushes it into the correct position, and locks it with the lock mechanism 22. As a result, the ready signal 2000 is generated as described above, and is supplied to the central processing unit 1 as an attention interrupt from the device 2-1.

Now, the central processing unit 1 of this embodiment has an OS (operating system) running therein.
However, when the above-mentioned attention interruption request is received, the request is accepted according to a predetermined priority order.

When this attention interrupt is accepted, the OS uses this as a trigger to immediately start the reader.

This reader is a processing program included in the OS, and when this reader is started, the peripheral device 2
The input peripheral device (in the current example, the floppy disk device 2-1) that generated the attention interrupt is identified, and the floppy disk medium 20 loaded in this floppy disk device 2-1 is identified. Read the file name for the data on this medium written in a predetermined area of Identifies that the information recorded in the file is a file consisting only of data.

Upon identifying this, the reader reads the data from the floppy disk device 2-1 at high speed, and reads the data from the disk device 2-1 as it has been read.
System disk (SD) installed in K
Store it as a data file in the empty space inside.

When all the series of data from the floppy disk device 2-1 have been read in this way, the reader identifies that data reading from the data medium 20 has been completed by detecting the data end of the input data.

Next, the reader uses the file name read above to generate a job control language that calls a JCL macro with the same name as the file name. This JCL macro is a JCL macro that defines in advance the execution environment of a processing program that should process a data file, gives it the same name as the data file that is to be processed, and creates a JCL macro that is provided in the system disk (SD). It is registered in the macro library.

Therefore, when the reader reads the above-mentioned file name and identifies from this name that this file contains only data, it immediately stores this data as a data file in the empty area of the reading system disk (SD). Next, generate a JCL that calls a JCL macro with the same name as the above file name, and use this JCL as an input stream to create each job that should process the data file created in the empty area of the system disk (SD) mentioned above. Register the job in a job input queue that is maintained in the form of a queue.

When this is completed, the OS outputs a lock release command to the floppy disk device 2-1, and this is supplied to the device 2-1 as the above-mentioned lock release signal 1000. As a result, as described above, the lock mechanism 22 is unlocked, and the floppy disk medium 20 is pushed out from the correct loading position by the action of the pushing mechanism 23, prompting the operator to remove the floppy disk medium 20 from the floppy disk medium 20. Indicates that data loading has been completed.

Now, when its turn comes, the above-mentioned processing program registered in the job input queue is removed from the input queue and started, and processes this data using the aforementioned data file stored in the system disk (SD) as an input file. Start automatically.

As described above, according to this embodiment, when a user obtains a floppy disk medium on which only data is recorded and has a file name registered in the system in advance, the user simply loads the floppy disk medium into the floppy disk device. It is possible to provide a system in which the rest of the processing for this data is carried out completely automatically. In particular, according to this embodiment, when the required data reading is completed, the loaded floppy disk medium is automatically pushed out from the correct loading position, clearly indicating to the operator that the data reading has been completed. .

In the above explanation, the input operation from a floppy disk medium has been explained, but it is also possible to input from the card reading device 2-2 using a card medium as a recording medium, or using a paper tape medium as a recording medium. When data is input from the paper tape reading device 2-3, the attention interrupt generated by loading these media and setting them in the ready state is handled in the same manner as described above. It is possible to start the above-mentioned reader as a start trigger for the data, thereby automatically reading data from these media, and when this is completed, automatically starting a processing program that processes this data in the same manner as described above. can.

FIG. 3 shows a flowchart of the above-described operation for inputting data from a floppy disk device.

(Effects of the Invention) As described above, according to the present invention, only data having a file name registered in advance in the system is recorded, and a recording medium in which this file name is recorded is simply loaded into a corresponding input peripheral device. Thus, it is possible to provide a data-driven scheduling method in which this data is automatically read and a processing program for processing this data is automatically started. Further, if the data medium is a floppy disk medium, when data reading is completed, the floppy disk medium is automatically pushed out from the correct loading position to clearly indicate to the operator that data reading has been completed.

As described above, anyone who is interested in the data to be processed can easily have a corresponding computer perform the necessary data processing, even if he or she is a beginner or amateur in the data processing operations of a general-purpose computer. It is possible to provide a similar operating environment. This allows computer operations to be made available to people without specialized knowledge.
