When the execution of processing is commanded, a receiving file name corresponding to the file name of a data file to be used for the processing is retrieved from the receiving file names of data files stored and managed by the file 15, and at the time of detecting the corresponding receiving file name, the commanded processing is executed by using the data file of the detected receiving file name.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal control device for receiving a data file transmitted from a terminal and executing an arbitrary process using the received data file, and a received file management method of the device.

[0002]

2. Description of the Related Art Each time a data file transmitted from a plurality of terminals is received, a reception management function for storing the data file in the received file and an arbitrary process using the data file stored in the received file are performed. In a conventional terminal control device having a processing control function to execute, when a data file having the same file name as the data file stored in the received file is received from the terminal, the data file having the same file name in the received file is stored in the received file. The contents of the data file received from the terminal may be overwritten, so that the original data may be lost or the data contents may be inconsistent.

Conventionally, reception of a data file having the same file name from a terminal is prohibited until a data file having the same file name is deleted from the received file. For this reason, even if an attempt is made to transmit a data file from the terminal to the terminal control device, if the data file having the same file name as the data file still remains in the reception file of the terminal control device, the data file can be transmitted. Instead, it must wait until the data file with the same file name is deleted from the received file.

[0004]

As described above, conventionally, when a data file having the same file name as a data file stored in a received file is transmitted from a terminal, the data file having the same file name is deleted from the received file. Since it is necessary to wait until the transmission is started, the work at the terminal may be hindered.

Although the above problem can be solved by setting the file name of the data file so as not to be duplicated in each terminal, the terminal control device does not use the file name of the data file used in the processing to be executed. The name is set in advance, and the terminal cannot change the file name of the data file without permission.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a data file having the same file name as a data file stored in a received file even if the data file is transmitted from a terminal. The terminal control device can manage reception without losing data or causing inconsistency, thereby improving the work efficiency of the terminal.

Thus, for example, when the inventory registration operation is performed using the portable terminal 2 belonging to the group 2A in the fresh fish counter and a data file in which the code, the quantity, the price, and the like of the inventory product are registered is created, the file name of this data file is [RF002001]. Similarly, when the inventory registration operation is performed using the portable terminal 2 belonging to the group 2B at the meat store and a data file in which the code, the quantity, the price, and the like of the inventory product are registered is created, the file name of this data file is [ RF0
02002].

Next, the terminal control device 1 will be specifically described. FIG. 4 is a block diagram showing a hardware configuration of the terminal control device 1.
PU (Central Processing Unit) 41, ROM (Read
OnlyMemoly) 42 and RAM (Random Access Memoly)
) 43, and these are connected by a bus line 44 such as an address bus and a data bus to constitute a control unit main body.

In addition to the system clock section 13, a communication controller 44 for controlling data communication with a host computer connected to the network, an FDD (Floppy Disk)
Drive) an FDD controller 46 for controlling the device 45;
HDD for controlling HDD (Hard Disc Drive) device 47
A controller 48, a keyboard interface 49 to which a keyboard is connected, a display interface 50 to which a display is connected, a printer interface 51 to which a printer is connected, and a wireless unit 52 for performing wireless data communication with each portable terminal 2 are connected. A wireless interface 53 and the like are mounted, and these are connected to the bus line 44, respectively.

In the terminal control device 1 having such a configuration, a program for realizing the reception management process function 11 and the processing control process function 12 is stored in the ROM 42. In the RAM 43, an area as the reception management file 14 and an area as the reception file 15 are secured.

The CPU 41 uses the wireless unit 52 to transmit a transmission start message 2 from any of the portable terminals 2.
1 is confirmed, the reception management process function 11 is started, and the processing shown in the flowchart of FIG. 7 is executed.

First, a transmission file name 34 is obtained from the transmission start message 21 received as ST (step) 1.
Also, as ST2, time data (hour, minute, second) measured by the system clock unit 13 is acquired as the reception time. Next, in ST3, a reception file name is created by adding the minutes and seconds of the reception time to the transmission file name 34. Thereafter, in ST4, the reception management file 14 is searched to determine whether the same reception file name is stored.

FIG. 5 shows the format of a record stored in the reception management file 14. As shown in the figure, in the reception management file 14, the reception file name of the data file stored in the reception file 15 and whether the data file is being received (01) or the reception completion (0
2) Stores a record including a status flag for identifying whether the data file is processed or processed (03) and the reception time of the data file. Incidentally, the reception file name is formed of 12 digits obtained by adding the minute (mm) and second (ss) of the reception time to the transmission file name (business code RF00x + store code 00y).

As a result of searching the reception management file 14 in ST4, when it is confirmed that there is no identical reception file name (YES in ST5), since the reception file name is a unique reception file name, the reception file name is determined as ST6. The reception management record including the status flag (01) indicating the reception and the reception time is added to the reception management file 14.
If the file area of the received file name is opened in the received file 15 in ST7, the transmission permission message 22 is transmitted to the portable terminal 2 of the transmission source identified by the transmission source ID of the transmission start message in ST8. Is transmitted from the wireless unit 52.

Thereafter, if the data file 23 is received from the portable terminal 2 of the transmission source via the wireless unit 52 in ST9, the data file 23 is stored in the open file area of the reception file 15 in ST10. . Then, when the transmission of the data file 23 is completed and the transmission end message 24 is received via the wireless unit 52, as ST12, the reception management file 14 is received.
, The status flag of the record with the corresponding received file name is updated from receiving (01) to receiving completed (02), and this processing ends.

If the same reception file name is detected as a result of the search of the reception management file 14 in ST4 (NO in ST5), 1 is added to the last digit of the reception file name in ST13, and the reception file is added. Change your name. Thereafter, the process returns to ST4 to search the reception management file 14 again. As a result, when it is confirmed that there is no identical received file name (YES in ST5), the processing after ST6 is executed.

Here, the ST of the reception management process function 11
Each of the processing blocks 1, 2, 3, 4, 5, and 13 converts a file name of a data file transmitted from the portable terminal 2 into information (minutes / seconds of the reception time) based on the reception time, and performs a unique processing. A reception file name obtaining means for obtaining a reception file name is configured.

The CPU 41 includes a communication controller 4
When the execution of an arbitrary process is instructed by a command input from a host computer connected via the PC 4 or an operation input of a keyboard connected to the keyboard interface 49, the process control process function 12 is started, and 8
The processing shown in the flowchart of FIG.

First, at ST1, a record counter n built in the CPU 41 is initialized to [1]. Next, ST
As 2, the reception management records are acquired from the reception management file 14 in the order corresponding to the value of the record counter n.
Next, as ST3, the first eight digits of the received file name of the received management record, that is, the transmitted file name, are acquired, and whether the transmitted file name matches the file name used in the processing instructed to be executed. Determine whether or not.
Then, when they match, the data file on the reception file 15 managed by the reception management record is a data file used in the execution commanded process,
In step ST5, the status flag of the reception management record is checked. Here, if the status flag indicates that reception has been completed (02), this data file is an unprocessed file,
As 6, the process instructed to execute is executed using this data file. Then, after the process is executed, if the status flag is updated to “processed” (03) in ST7, the process proceeds to ST8.

On the other hand, if the status flag is “receiving” (01) or processed (03) in ST5, the process proceeds to ST8 without executing the process. Also, if the transmission file name does not match the file name used in the processing instructed in ST4, the process proceeds to ST8 without executing the processing.

In ST8, the record counter n is counted up by [1]. Thereafter, as ST9, the counter n indicates the number of records N in the reception management file 4.
If it is confirmed that the value does not exceed the value, the process returns to ST2. In this manner, for all the reception management records stored in the reception management file 14, it is determined whether or not the transmission file names acquired from the reception file names match the file names used in the processing instructed to execute. Executes the process using the corresponding data file on the reception file 15. If the record counter n exceeds the number N of records in the reception management file 14 in ST9,
This processing ends.

In the present embodiment, the processes controlled by the process control process function 12 include, for example, the following processes (1) to (4).

(1) A merchandise master file stored in the HDD device 47 with merchandise information such as a merchandise name and a price corresponding to a barcode registered in a data file created by a barcode check operation on the portable terminal 2. Processing to read from the display on the display. (2) A process in which data such as the product name, quantity, and price of each stock product registered in the data file created by the inventory registration process in the portable terminal 2 is printed out by the printer. (3) A process of updating the price in the product master file of the product to be changed registered in the data file created by the product price change operation in the portable terminal 2 to the unit price after the change. (4) The code of the order target product registered in the data file created by the order registration work on the portable terminal 2,
A process for placing an order by transmitting data such as the number of orders and the desired date of delivery together to a higher-level computer connected via the communication controller 44.

Here, the ST of the processing control process function 12
Each of the processing blocks 1, 2, 3, 8, and 9 corresponds to the file name of the data file used in the process instructed to execute from the reception file names of the data files stored and managed in the reception file 15. A reception file name search means for searching for a reception file name is configured.

The CPU 41 periodically performs maintenance of the received file 15 as follows. That is, the status flags are checked in order from the first record of the reception management file 14. When a record that has been processed (03) is detected, the data file on the reception file 15 managed by the reception file name in the record is deleted. If all the records in the reception management file 14 have been checked in this way, all the records whose status flags have been processed (03) are deleted, and if the remaining records are sorted, this maintenance is finished.

As described above, in this embodiment, when the person in charge performs the barcode check, the inventory registration, the commodity price change, the order registration and the like using the portable terminal 2 at each sales floor, the work is performed. Is created, and the data file is transmitted to the terminal control device 1. At this time, the transmission file name is the job code (RF00x) of the execution job and the sales floor code (0
0x). For this reason, when a plurality of portable terminals 2 are used at the same sales floor to execute the same business and transmit a data file to the terminal control device 1 at approximately the same time, a data file having a common transmission file name is transmitted at approximately the same time. This is transmitted to the terminal control device 1. In this case, conventionally, the content of the data file transmitted later is overwritten on the data file previously written in the received file, and there is a possibility that necessary data is lost or inconsistency occurs.

However, in the present embodiment, each time the terminal control device 1 receives a data file from the portable terminal 2, the terminal control device 1 creates the received file name by adding the minute and second of the reception time to the transmission file name. Then, the data file is stored in the reception file 15 with this reception file name. Therefore, if the reception time is shifted by even one second, even if the data file has the same transmission file name, the received file name is different, so that the received file 15 can be stored and managed as separate files. Even if a data file with the same transmission file name is received within one second, the reception time added to the transmission file name of one data file is automatically advanced by one second. There is no possibility of duplication, and in this case, the received file 15 can be stored and managed as separate files.

In the terminal control device 1, the data file received from each portable terminal 2 is stored and managed in the reception file 15 with a reception file name different from the transmission file name. When a command is issued, the transmission file name is obtained from the reception file name, and it is determined whether the transmission file name matches the file name of the data file used in the relevant process. Can be detected from the received file 15 and processed. As a result, there is no possibility that the processing in the terminal control device 1 will be hindered.

For example, an order registration operation is now performed using three portable terminals 2 at the fresh fish counter.
It is assumed that the data file of the transmission file name [RF004001] is transmitted from the first portable terminal 2 at 5:23. Then, the reception file name is obtained by adding the minute and second of the reception time to the transmission file name [RF004001152.
3]. 6 in the reception management file 14.
The reception management record indicated by 1 is written.

Next, it is assumed that a data file having the same transmission file name [RF004001] is transmitted from the second portable terminal 2 at the same time. Then, the reception file name is obtained by adding the minute and second of the reception time to the transmission file name [R
F0040011523], but since this file name exists as a record 61 in the reception management file 14, the reception time is advanced by one second [RF004001152].
4]. 6 in the reception management file 14.
The reception management record indicated by 2 is written.

Next, one second later (11:15:24),
From the second portable terminal 2, the transmission file name [RF0040
01] has been transmitted. Then, the received file name is [RF0040011524] obtained by adding the minute and second of the reception time to the transmission file name. Since this file name exists as the record 62 in the reception management file 14, the reception time is advanced by one second [ R
F0040011525]. Then, the reception management record indicated by 63 in FIG.

As described above, according to the present embodiment, even if a data file having the same transmission file name as the data file stored in reception file 15 is transmitted from portable terminal 2, the original data is lost. Therefore, the portable terminal 2 has to wait for the transmission of the data file until the data file with the same transmission file name is deleted from the reception file 15 because the reception management can be performed without causing the occurrence of inconsistency. Waste time can be eliminated. As a result, the work efficiency of the portable terminal 2 is improved. Further, since it is not necessary to change the transmission file name of the data file in the portable terminal 2, the work efficiency can be improved from this point as well.

The present invention is not limited to the above embodiment. For example, in the above-described embodiment, the reception time data is used as the information based on the reception time for converting the file name. For example, a counter that counts the number of receptions of the transmission start message 21 transmitted from the portable terminal 2 is used. And the transmitted file name can be converted into a unique received file name using the value of this counter.

The terminal is not limited to a portable terminal, and it goes without saying that the present invention can be similarly applied to a stationary terminal. In addition, the method of setting the transmission file name of the data file added by the terminal, the type of processing to be executed by the terminal control device 1,
Of course, various modifications can be made without departing from the spirit of the present invention.

[0044]

As described in detail above, according to the present invention,
Even if a data file having the same file name as the data file stored in the received file is transmitted from the terminal, reception management can be performed by the terminal control device without losing the original data or causing inconsistency. . Therefore, the operation efficiency of the terminal can be improved.
