Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a distributed processing system composed of a terminal device and a host device connected to the terminal device through a communication path. The present invention relates to a data input processing method in a distributed processing system in which data is input from an input device, transmitted to a host device, and the data received by the host device is processed.

[0002]

2. Description of the Related Art Conventionally, in this type of distributed processing system, data concerning each work input from an input device of a terminal device is unconditionally mixed and stored in one data file, and this data is stored. The transmitted data is transmitted to the host device.

[0003]

With the above-mentioned configuration, it is possible to transmit the data of each work input from the terminal device to the higher-level device, but one data file contains input data of a plurality of works. Since they are mixed and accumulated,
If a large data file is required and there is an input error in the data entered for a certain job, the input data for other jobs are also stored in the data file, so only the data for the job is deleted. However, there is a risk that input data of other jobs may be deleted by mistake even if it is difficult.

The present invention has been made in view of the above circumstances, and an object thereof is to ensure that only a small-capacity data file is required and that, when an input error occurs, only the input data relating to the job is surely deleted. It is an object of the present invention to provide a data input processing method in a distributed processing system capable of performing.

[0005]

In order to achieve the above object, the present invention comprises a terminal device and a host device connected to the terminal device through a communication path. In a distributed processing system for inputting data related to the business from an input device, transmitting the data to the higher-level device through the communication path, and processing the data received by the higher-level device, a business process corresponding to each business in the terminal Section, a terminal task selection processing section for selecting and activating any one of the plurality of task processing sections, and a data file exclusively shared by the plurality of task processing sections, The business processing unit selected and activated by the terminal business selection processing unit writes the data input from the input device to the data file, and writes the written data through the communication path. Until delete all contents of the data file including or the written data is transmitted to the host device, the selection of different business processing unit is prevented from performing by the terminal operation selection unit.

Further, the terminal job selection processing unit has a configuration for selecting and starting a job processing unit corresponding to a job instructed through a job selection screen displayed on a display device. A data reception file for accumulating data received from the terminal device, and a data search processing unit for searching the data reception file to obtain data for each job are provided.

[0007]

In the data input processing method in the distributed processing system of the present invention, the terminal job selection processing unit provided in the terminal device operates through the job selection screen displayed on the display device among the plurality of job processing units corresponding to each job. When the business processing unit corresponding to the business designated by the user is selected and started, the started business processing unit inputs data from the input device, writes the data file, deletes all the contents of the data file, The data stored in the data file is transmitted to the host device. Then, in this case, the started business processing unit writes the data input from the input device to the data file and transmits the written data to the host device or deletes all the contents of the data file including the written data. The terminal work selection processing unit does not select another work processing unit. That is, each business process is exclusively performed. As a result, since only one job data is stored in the data file at a time, a small capacity is sufficient, and the data can be deleted easily and without affecting other job data.

[0008]

Embodiments of the present invention will now be described in detail with reference to the drawings.

Referring to FIG. 1, an example of a distributed processing system to which the present invention is applied is composed of a terminal device 1 and a host device 2 connected to the terminal device 1 via a communication path 3.

The terminal device 1 is a device for inputting data relating to a plurality of jobs from an operator and transmitting the data to the higher-level device 2 through the communication path 3, and displays a job selection screen and an input screen for each job. A CRT 11 to be displayed, a keyboard 12 for inputting data, a terminal task selection processing section 14, a task processing section 15 for performing processing relating to a certain task A, another certain task B
It has a business processing unit 16 for performing the above process and a data file 17 exclusively shared by the business processing units 15 and 16.

On the other hand, the host device 2 is a device for receiving the data transmitted from the terminal device 1 and processing the received data. The host device data reception processing section 21, the data reception file 22, and the data retrieval. It has a processing unit 23 and a printer 24.

In the example of FIG. 1, two business processing units 1
Although the terminal devices provided with 5, 16 are shown, the number of business processing units is not limited to this.

FIG. 2 is a flow chart showing the outline of the processing of the terminal device 1 of FIG. 1. The operation of this embodiment will be described below with reference to the drawings.

In the initial state where no input processing for any business is performed, no significant information is stored in the data file 17, and the terminal device 1 is transferred to the CRT 11 by the terminal business selection processing unit 14. A job selection screen that prompts the user to enter a job number that identifies the job to be selected is displayed, and the operation number is awaited (S1).

When the operator of the terminal device 1 inputs the business number of the business A from the keyboard 12 through the business selection screen displayed on the CRT 11 in order to perform the input business related to the business A, for example, the terminal business selection processing unit 14 Processing S1 of FIG.
At, the business processing unit 15 corresponding to the business A is activated.

The started work processing unit 15 has S2 to S2 in FIG.
The process of S9 is executed.

First, the input screen for work A is displayed on the CRT 11 to wait for data input. When the user inputs data by operating the keyboard 12, the data is taken in (S2), and the data concerned is data for work A. It is stored in the data file 17 with the business name and the like added so that it can be understood that it is (S3).

When the operator of the terminal device 1 continuously inputs data (YES in S4), the process returns to the process S2 and the above-mentioned processes are repeated.

Further, if the operator of the terminal device 1 notices that the data already input is incorrect, and instead of inputting the data, an instruction to delete the data is given by operating the keyboard 12 (NO in S4, YES in S5). ), Business processing unit 1
5 deletes all the data stored in the data file 17 (S6). Then, at this point, control is returned from the work processing unit 15 to the terminal work selection processing unit 14, and the terminal work selection processing unit 14 again displays the work selection screen on the CRT 11 and accepts the selection of the work (S1).

On the other hand, if data transmission is instructed by operating the keyboard 12 or the like instead of deleting data (N in S5)
O), the work processing unit 15 transmits all the data accumulated in the data file 17 to the higher-level device 2 through the communication path 3 (S7), and checks whether the transmission is normally completed (S8), and the normal end is performed. In the case of, all contents of the data file 17 are cleared (S9). Then, at this point, control is returned from the work processing unit 15 to the terminal work selection processing unit 14,
The terminal job selection processing unit 14 displays the job selection screen on the CRT 11 again and accepts the job selection (S1). Also,
When the transmission is not normally completed, the business processing unit 15 performs the processing S2.
Then, the processing described above is repeated.

The above is the operation when the business processing unit 15 is selected, but the same operation is performed when the business processing unit 16 corresponding to the business B is selected.

As described above, in the terminal device 1, one business processing section inputs data from the operator and writes the data in the data file 17, and the written data is written in the host device 2.
Until the entire content of the data file 17 including the transmitted data or the written data is deleted, another business processing unit does not operate.

Now, in the host device 2, the terminal device 1
Each time data is sent from the communication device 3 via the communication path 3, the host device data reception processing unit 21 receives it and stores it in the data reception file 22. Therefore, the data reception file 22 stores the input data relating to the plurality of jobs A and B. Therefore, in the actual processing, the data search processing unit 23 searches the data of the data reception file 22 for each business, and processes the data of each business obtained by this search. Although the higher-level device 2 in FIG. 1 performs data processing for outputting the data for each job searched by the data search processing unit 23 to the printer 24, it goes without saying that the present invention is not limited to such processing.

[0024]

According to the data input processing method in the distributed processing system of the present invention described above, the following effects can be obtained.

In the terminal device, the started business processing unit writes the data input from the input device to the data file and transmits the written data to the host device or deletes the entire contents of the data file including the written data. Until then, another business processing unit is prevented from operating, so that only one business data is stored in the data file at one time, and a small capacity data file is sufficient. Further, the data can be easily deleted when an input error occurs without affecting other business data.

By transmitting the data immediately after the data is input, the data can be transmitted in units of one work, and the processing when the input data of the terminal device is used by the host device is facilitated because it is one transmission and one work data.
