Abstract

PURPOSE:To update the generated data in real time by providing a means which takes the data on the same code as the identification code of the received data out of a data storage means and updating the data into the received new data. CONSTITUTION:A communication controller 12 transmits the data including an identification code of a data processor 11 via a communication circuit 13. Meanwhile a communication controller 14 of a host device sends the received data to a CPU 15. The CPU 15 updates the original data on a hard disk 16 based on the identification code added to the data. Thus the generated data can be updated into the real data in real time. As a result, no production loss is crused when the data are updated in real time on a production line for example. The the production efficiency is improved.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is an information processing system consisting of a host II and an external terminal connected online, which automatically updates data sent from the external terminal. Related to automatic data processing equipment.

[Prior Art] FIG. 3 is an example of a conventional system for managing frequently occurring data, such as product sales information.

The data processing device 1 generates data such as product sales information, and this data is stored in the data recording device 2.
is recorded on the hard disk 3 or floppy disk 4. When recording the data of the data processing device 1 on the hard disk 5 of the host machine and updating the original data, the floppy disk 4 is carried to the host machine and the floppy disk 4 is set in the data input device 6. Incidentally, if the data of the data processing device 1 has been recorded on the hard disk 3, the data shall be transferred to the floppy disk 4.

When the floppy disk 4 is set in the data input device 6, the data on the floppy disk 4 is transferred to the hard disk 5 by the C20 (central processing unit) 7. The original data stored on the hard disk 5 is then updated with the transferred new data. The data updated in this way is printed by the printer 8. Further, one communication control device 9 can access the hard disk 5 and search for data in accordance with instructions from the graphic display keyboard IO.

[Problems to be Solved by the Invention] However, such conventional systems temporarily store data on the external terminal that generates the data, and periodically record this data on the host's hard disk to update the data. The method was to do this. As a result, there was a so-called time lag, which not only made it impossible to ascertain the current and accurate data, but also made it impossible to perform online searches when updating data.

In particular, because data cannot be updated in real time, for example, if the data is necessary for manufacturing a product, there may be delays in understanding the ever-changing data, which may ultimately lead to production loss. there were.

The present invention has been made to solve these problems, and its purpose is to provide an automatic data processing device that can update generated data in real time and prevent data time lag. .

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a means for adding an identification code to data to be transmitted and transmitting it via a communication line, and an identification code for the data transmitted by this means. The present invention is characterized in that it has means for extracting data of the same code from the data storage storage means and updating it to the received new data.

[Operation] In the present invention, an identification code for distinguishing the data is added to the generated data and then transmitted. This identification code is also added to the original data recorded in the storage means. Therefore, the data update process is executed by reading data with the same identification code from the storage means and modifying the data to new data. This makes it possible to update data to actual data in real time.

[Examples] Examples of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of an automatic data processing device of the present invention.

In FIG. 1, reference numeral 11 denotes a data processing device that generates data, and an identification code is added to the data generated here. That is, the communication control device 12 is designed to add an identification code for distinguishing data to each type of data, and to manage each data type.
Data with an identification code of 1 is transmitted via the communication line 13.

The data processing device M11 and the communication control device 12 constitute an external terminal, and the external terminal and the host device are connected by the communication line 13 described above.

On the other hand, the host machine mainly includes the communication control device 14 and the CPU 15.
．． It consists of a hard disk 16.

The communication control device 14 receives the transmitted data from the CPU 1.
5, and the CPU 15 updates the original data on the hard disk 16 based on the identification code added to the data, which will be described in detail later. Further, in the figure, 17 is a printer, 18 is a graphic display, and 19 is its keyboard. Further, the data stored in the hard disk 16 can be searched by operating the keyboard 19 or printed by the printer 17.

Next, the data update process will be explained in detail with reference to FIG.

20 in the figure is data generated by the data processing device 11, and as described above, an identification code 21 is added to the beginning of the data. The data 20 to which this identification code has been added is received by the communication control device 14, and the communication queue 22 inside the communication control device 14 receives the data 20.
The data in the zero communication queue 22 that is temporarily stored is sent as message data to the CPU 15, where it is updated. The procedure for this update process is to first update the CPU
15 is a CPU that calls the update program 23 corresponding to the identification code added to the data from a memory (not shown);
15 uses this update program 23 to read data with the same identification code from the 8-hard disk 16,
Erase that data. Then, the newly sent data is written to the hard disk 16 again as the latest data, and the update process is completed.

Further, 24 indicates a search program for searching data stored in the hard disk 16. When a data search is instructed from the keyboard 19, the CPU 15 accesses the hard disk 16 according to the search program 24 and searches for updated data.

In addition, in the above embodiment, an example was shown in which the data in the data processing device 1 is automatically updated, but it is also possible to update the data in the hard disk by starting an update program from a graphic display type terminal. Further, the present invention and the conventional system may be used together. In other words, if data that changes from moment to moment occurs around the clock, using the conventional system at night and using the present invention during the day will not only reduce the load on the host machine, but also provide backup in the event of a failure. It also has the advantage of being

[Effects of the Invention] As explained above, according to the present invention, an identification code is added to data, and data with the same code as the code is read out and updated to new data. Data can be updated in real time, and time lag between actual data and data recorded on the disc can be prevented.

Therefore, it is possible to grasp actual data in real time, and for example, if real-time data is updated on a production line, production loss will not occur and production efficiency can be improved. Furthermore, since there is no human intervention at all from the time the data is generated until it is processed, there is an advantage that the accuracy of the data can be improved.
