Abstract

PROBLEM TO BE SOLVED: To obtain the consistency of set data between respective terminals by mutually grasping the states of set data in opposite terminals, and executing copying operation when copied set data are equivalent to copying source unchanged set data. SOLUTION: Respective terminals 1 to 4 and a floppy disk(FD) 5 are respectively provided with KEY memories 6a to 10a, and at the time of copying set data, the identification(ID) of an opposite terminal is set up as copy history data. When the set data of a terminal itself is changed, its ID is cleared. In the case of copying set data from an external (another terminal or FD), whether copied set data are equivalent to the copying source unchanged set data or not can be discriminted by referring to the ID, and when both the set data are mutually equivalent, the set data are copied as they are, so that the consistency of set data between respective terminals can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to, for example, POS (po
int of sale) The present invention relates to a data processing system in which a plurality of terminals exist in a distributed manner, such as a system. In particular, a data processing system in which setting data can be changed in each terminal, and a recording medium storing a processing program for the setting data About.

[0002]

2. Description of the Related Art Conventionally, in a data processing system such as a POS system, a plurality of terminals exist in a distributed manner.
Each can change the setting data. The setting data is data for setting the format of the file, and for example, defines the number of items in the form, the position of the items, and the like. Each terminal can create a file using its own setting data.

[0003] When setting data is changed (upgraded), if all terminals are always connected by a line, the setting data for all the devices can be changed in real time in common. The consistency of the setting data can be maintained. However, when the terminals are not always connected by a line, the setting data cannot be changed in all terminals in common, and it is impossible to maintain the consistency of the setting data between the terminals.

[0004]

For example, when setting data is copied from a certain terminal to another terminal, it is necessary that the setting data of the copy destination is equal to the setting data before the change of the copy source. This is because the setting data must always be changed stepwise based on the previous state. If the setting data of the copy destination is equivalent to the setting data before the change of the copy source, the copy destination can change its own setting data according to the setting data by copying the setting data of the copy source. it can.

[0005] However, when the terminals are not always connected by a line, it is not possible for each terminal to judge the state (version) of the other party's setting data. For this reason, when the setting data is copied, the copy is executed even though the setting data of the copy destination is different from the setting data before the change of the copy source, and a difference in data is found later. At that point, there were problems such as manual correction.

The present invention has been made in view of the above points, and it is possible for each terminal to grasp the state of the setting data of the other party, and to check the setting data of the copy destination before the change of the copy source. It is an object of the present invention to provide a data processing system and a recording medium storing a data processing program in which setting data is made consistent between terminals by copying when the setting data is equivalent to the setting data.

[0007]

SUMMARY OF THE INVENTION The present invention is a data processing system having a plurality of terminals, each of which is capable of changing setting data. Storage control means for storing the copy history data at both the copy destination and the copy source; and setting data of the copy destination are copied based on the copy history data stored at both the copy destination and the copy source by the storage control means. Determining means for determining whether or not the setting data before the original change is equivalent to the setting data before the change; when the setting data of the copy destination is determined to be equivalent to the setting data before the change of the copy source by the determining means, And copy control means for copying the current setting data of the copy source to the copy destination.

According to this configuration, when setting data is copied from an external device (another terminal or a floppy disk), the copy destination is set based on the copy history data stored in both the copy destination and the copy source. It is possible to determine whether or not the data is equivalent to the setting data before the change of the copy source. If the data is equivalent, the setting data can be copied as it is, and the consistency of the setting data can be obtained between the terminals.

Further, according to the present invention, the identification data of the other party is stored as the copy history data, and the identification data is cleared when there is a change in the set data of the other party. When the identification data matches the other party's identification data, it is determined that the copy destination setting data is equivalent to the copy source setting data before the change (claim 2).

As described above, if the identification data of the other party is stored as copy history data when the setting data is copied, it is unlikely that the copy history data will be duplicated. Thus, the setting data can be copied.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing a configuration of a data processing system according to one embodiment of the present invention. Here, a POS system is taken as an example of a data processing system having a plurality of terminals. In the POS system, sales information, purchases, and sales information collected by individual items
It sends various information generated during activities such as delivery to a computer, processes it into information that can be used effectively by each department, and transmits it.

In FIG. 1, ECRs (electronic cash registers) 1 and ECRs 2 are installed in department stores, supermarkets, specialty stores, retail stores, and the like, and are used as POS terminal devices. Although only two are shown here, there are actually a plurality (ECR1... ECRn). These E
CR1 and ECR2 can be connected to each other online, and can also be connected to PC3 via a connector.

A PC (personal computer) 3
Exists as an upper device of CR1 and ECR2,
And the data sequentially transferred from ECR2. The SC (store controller) 4 is for centrally managing data compiled by the PC 3, and here, the PC 3
And a communication line.

[0015] These terminals (1 to 4) are distributed in the store or for each region, and each can change the setting data. The setting data is data for setting the format of the file, and for example, defines the number of items in the form, the position of the items, and the like. Each terminal (1-4)
Can create files using their own setting data. Further, it is also possible to use an FD (floppy disk) 5 to share data stored therein between terminals.

Here, the terminals (1 to 4) are not always connected by a line. For this reason, when setting data from another terminal or the FD 5 is copied from any terminal, there is a problem that it is not possible to determine what state (version) the setting data of the other party is in.

Therefore, in the present embodiment, each terminal (1 to
4) Data files 6 to 9 and FD5 data file 1
0 are provided with key memories 6a to 10a, respectively.
By storing the ID (identification data) of the other party as copy history data in the EY memories 6a to 10a, the state of the setting data of the other party can be grasped.

The KEY memories 6a to 10a store I
In addition to D, setting data of the terminal is stored (see FIG. 8). For example, in the case of ECR1, setting data for each file is stored in the key memory 6a provided in the data file 6. "PLU file 1", "Department file 1", "Time zone file" of ECR1
Is created based on this setting data.

Similarly, in the case of the ECR 2, the setting data for each file is stored in the KEY memory 7a provided in the data file 7. “PLU file 1”, “department file 2”, and “time tally file” of ECR2 are created based on the setting data.

FIG. 2 is a diagram showing transition of IDs set in the key memory. Now, four terminals (2 ECRs, P
It is assumed that, in an offline system operated by two C), setting data is changed in each of the terminals A to D and the setting data is copied to another terminal.

In the initial state (No. 00), each of the terminals A to
All IDs of the D key memory are cleared.

Here, for example, when the setting data is transmitted from the terminal A to the terminal B, and the terminal B copies the setting data of the terminal A (No. 01), the status of the setting data of the other party at this time is unknown. Therefore, a warning is issued to the terminal B indicating that copying cannot be performed as it is.

If terminal B copies the setting data of terminal A, the key memory of terminal A stores the I
D is set, and the I key of the terminal A is stored in the KEY memory of the terminal B.
D is set. Thus, terminal A knows that its own setting data is the same as terminal B, and terminal B knows that its own setting data is the same as terminal A.

Next, it is assumed that the terminal A has independently changed the setting data (No. 02). In this case, since it is a single change,
ID of terminal B set in KEY memory of terminal A
Is cleared. On the other hand, in the terminal B, even if the terminal A alone changes, the ID of the terminal A is held in the KEY memory of the terminal B as it is because the terminal A has the setting data from which the change is made.

In this state, it is assumed that the setting data is transmitted from terminal A to terminal B (No. 03). In this case, terminal B
Since the ID of the terminal A is set in the KEY memory, the setting data of the copy destination (terminal B) is equivalent to the setting data of the copy source (terminal A) before the change by referring to this ID. Can be determined. Therefore, the terminal B can copy the setting data of the terminal A as it is without warning (the setting data of the terminal B can be rewritten in the same manner as the terminal A). After copying, terminal A
The ID of the terminal B is set in the KEY memory.

If the terminal B alone changes the setting data (No. 04), the ID of the terminal A set in the key memory of the terminal B is cleared. At this time, the ID of the terminal B is held in the KEY memory of the terminal A as it is.

In this state, when the setting data is transmitted from the terminal A to the terminal B (No. 05), since the ID of the terminal A is not set in the key memory of the terminal B, the setting of the copy destination (terminal B) is performed. It is determined that the data is not equivalent to the setting data before the change of the copy source (terminal A), and a warning is issued to terminal B.

Similarly, when the setting data is copied between the terminals, the ID of the other party is stored in each key memory.
Is set as copy history data, and if its own setting data is independently changed, its own ID is cleared. If no ID match is obtained at the time of copying, a warning is issued to the terminal.

It should be noted that it is possible to include the FD as a copy source.
Of the other party is set in the KEY memory, and the ID is cleared by independent change.

The storage medium 13a includes the FD 5 shown in FIG. 1, and stores the data file 10 having the KEY memory 10a here.

FIG. 4 is a block diagram showing the configuration of the PC 4.

The PC 4 has a CPU 21.

The CPU 21 responds to switch / key operation data input from the input device 22 by using system program data stored in advance in the storage device 23 and various types of data read from the storage medium 23a via the storage device 23.

As the display device 25, for example, a liquid crystal display device is used, and data corresponding to an input operation on the input device 22 is displayed.

Data corresponding to an input operation on the input device 22 is printed on the printing device 26.

The storage medium 23a stores the FD shown in FIG.
5, where a data file 10 having a key memory 10a is stored.

Next, the processing operation of each terminal (1 to 4) shown in FIG. 1 will be described.

FIG. 5 is a flowchart showing the overall processing flow of each terminal.

Each of the terminals (1 to 4) is waiting for an input (step A11), and receives setting data from another terminal during that time (step A12: Yes).
The receiving process of the setting data is performed (step A13).
When transmitting the own setting data to another terminal (Yes in step A14), the transmission processing is performed (step A15).

On the other hand, if there is any input (step A
11 (Yes), the input data is analyzed (step A16). As a result, if the input data indicates data setting, data setting processing is performed (step A17). If the input data indicates data copying, data copying processing is performed (step A18) and registration is instructed. If it does, a registration process is performed (step A1).
9).

These processes are performed in common by the terminals (1 to 4). For example, in the case of ECR1, the CPU 11 shown in FIG. 3 is read out from a program stored in the storage device 23 or from the storage medium 23a. It is executed by activating the program to be transferred and the program transferred via the communication line 23b. In the case of the PC 3, the CPU 21 shown in FIG.

Next, the data setting process executed in step A17 will be described.

FIG. 6 is a flowchart showing the operation of the data setting process.

When the data setting is instructed, the terminal rewrites its own setting data (step B11). In this case, the setting data is stored in the KEY memory. For example, in the case of ECR1, K of the data file 6 shown in FIG.
The setting data for each file is stored in the EY memory 6a. The CPU 11 of the ECR 1 accesses the KEY memory 6a of the data file 6 stored in the RAM 14, and rewrites the setting data stored therein according to the instruction. By rewriting the setting data, the format of the file (for example, the number of items in the form, the position of the items, etc.) is changed.

After rewriting the setting data, the terminal clears the ID set in its own KYE memory (step B12). For example, if ECR1, EC
When R1 alone rewrites the setting data, the ID set in the KEY memory 6a of the data file 6 shown in FIG. 1 is cleared.

As described above, when the setting data is changed by the terminal alone, the ID set in the own key memory is changed.
Is cleared. This state corresponds to N in the transition diagram of FIG.
o. Equivalent to 2.

The data copy processing executed in step A18 will be described.

FIG. 7 is a flowchart showing the operation of the data copy process executed in step A18. The data copy processing is to receive setting data from the outside (another terminal or FD) and rewrite (overwrite) own setting data in accordance with the setting data.

When the data copy is instructed, the terminal first determines whether or not the ID of the other party exists in its own key memory (step C11). As a result, if the partner ID exists (Yes in step C11), it can be determined that the copy destination setting data is equivalent to the copy source setting data before the change. Therefore, the terminal overwrites the external setting data with its own setting data (step C12).

For example, when setting data is copied from ECR1 to ECR2 in FIG.
And rewrites the setting data stored in its own key memory 7a in accordance with the setting data. In this case, since the setting data of the copy destination is equivalent to the setting data of the copy source before the change, there is no need for a warning at the time of copying. This state corresponds to No. in the transition diagram of FIG. Equivalent to 3.

On the other hand, if the other party's ID does not exist (No in step C11), the terminal compares its own setting data with the other party's setting data (step C1).
3). The setting data of the other party is the setting data of the copy source terminal or the FD. As a result of the comparison, if it is the same as the setting data of the other party (Yes in step C13), there is no need to copy, so the terminal sets the ID of the other party in its own KEY memory (step C14),
The user's own ID is set in the key memory of the other party (step C15), and the processing here ends.

If the data differs from the setting data of the other party (Yes in step C13), the data cannot be copied as it is. Therefore, the terminal obtains the difference between the two setting data, and displays the difference data together with the guidance (step C16).

Specifically, for example, in the case of ECR1, the CPU 11 shown in FIG. 3 obtains difference data between the setting data stored in the RAM 14 and the setting data obtained via the communication line 13b, and calculates the difference data. Processing such as displaying on the display device 16 together with the guidance is performed. This state corresponds to No. in the transition diagram of FIG. Equivalent to 5. By this guidance display, the user of the terminal can confirm that the setting data of the other party cannot be copied as it is.

Thereafter, it is assumed that the user of the terminal instructs to overwrite the setting data of the other party (step C).
17 Yes), the other party's setting data is overwritten on the terminal, and the difference data is added thereto (step C).
18). At this time, the terminal sets the ID of the other party in its own key memory (step C1).
9) The user's own ID is set in the key memory of the other party (step C20), and the processing here ends.

This situation will be specifically described with reference to FIG.

In the example of FIG. 8, the copy source is an FD (floppy disk). Now, the setting data A and the setting data B are stored in the KEY memory 31 of a certain terminal.
It is assumed that the setting data A and the setting data C are stored in the key memory 32 on the FD side. In addition, I on the terminal side
D is “1”, the ID of the FD is “2”, and it is assumed that the ID of the other party is not set in the initial state.

Here, when the setting data A and C possessed by the FD are copied to the terminal, the ID of the FD which is the copy source does not exist in the key memory 31 of the terminal which is the copy destination. Is different, a warning is issued to the terminal side. In such a case, after confirming with the user on the terminal side, the setting data of the FD is overwritten,
Then, the difference data CB between the two is added. As a result, the setting data of the terminal is changed to A, B, and CB. At this time, the KEY memory 3 on the terminal side is used.
1 is set to “2” which is the ID of the FD, and “1” which is the ID of the terminal is set to the KEY memory 32 on the FD side.

As described above, by setting the ID of the other party in the key memory at the time of copying the setting data,
D can be used as copy history data. This makes it possible to determine whether the setting data at the copy destination is equivalent to the setting data before the change at the copy source, and if so, by copying the setting data as it is, the consistency of the setting data between the terminals. Sex can be taken.

As a modification, for example, a random generating means is provided, and random data is generated at the start of copying.
This may be used as copy history data.

The method described in the above embodiment, that is, the overall processing of each terminal shown in the flowchart of FIG. 5, the data setting processing shown in the flowchart of FIG. 6, the data copy processing shown in the flowchart of FIG. Each method is a program that can be executed by a computer, such as a memory card (ROM card, RAM card, etc.), a magnetic disk (floppy disk, hard disk, etc.), an optical disk (CD-ROM, DVD).
Etc.), and can be stored in a storage medium (13a, 23a) such as a semiconductor memory and distributed, or transmitted via a communication line (13b, 23b).

The computer stores the storage medium (13a,
23a) and programs and communication lines (13b,
23b) stores the program transmitted via the storage device (1
By reading in (3, 23) and controlling the operation by the read program, the functions described in the above embodiment can be realized, and the same processing can be performed by the above-described method.

[0075]

As described above, according to the first aspect of the present invention, when setting data from an external device (another terminal or a floppy disk) is copied, the copy data stored in both the copy destination and the copy source are copied. From the history data, it is possible to determine whether or not the setting data of the copy destination is equivalent to the setting data before the change of the copy source. If the setting data is equal, the setting data is copied as it is, so that the Consistency can be achieved.

According to the second aspect of the present invention, when the setting data is copied, the other party's identification data is stored as copy history data. Can be performed.
