Abstract

PURPOSE:To accurately acquire sales data without increasing the storage capacity by additionally registering or transferring a single article code of sales data in accordance with the presence or the absence of the idle capacity in the case that this single article code is not registered in a relay file yet. CONSTITUTION:When single article sales data is received from a POS terminal, 1a, it is discriminated whether the single article code of single article sales data is already registered in the single article code area of a relay file 7a or not; and if it is already registered there, this sales data is added to sales data of the pertinent single article code in the relay fule 7a. If it is not registered there, it is checked whether or not the relay file 7a has the idle capacity equal to or larger than a prescribed capacity; and if it has this idle capacity, received single article sales data is additionally registered in the relay file 7a. If it does not have this idle capacity, received single article sales data is transferred to a store processor 4 through a communication line 5. Thus, commodity- classified sales total data is accurately acquired without increasing the storage capacity of the relay file.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sales data processing device used as a file processor of a POS (point of sale information management) system.

[0002]

2. Description of the Related Art A POS system introduced in a large-scale supermarket or the like divides a large number of sales commodity registration terminals, so-called POS terminals, which are installed in respective sales floors into a plurality of groups, and each group has its own terminal. One file processor is arranged and each POS terminal in the same group is connected to the file processor by a communication line. In addition, a file controller of each group is connected to a so-called store processor, which is a store controller that controls the sales of the entire store, by a communication line.

[0003] Then, the individual code, name, set to the store processor for all products sold in the store,
In addition to preset storage of product information such as unit price, a single product master file is provided for cumulatively storing sales data such as the number of items sold and the amount of money for each product. Further, each file processor is provided with a relay file for temporarily storing sales data of each product, thereby constructing a system.

However, when the file processor collects the single-item sales data including the single-item code of the product registered for sale at each POS terminal connected to the line, the number of sales, and the sales amount, the single-item code of the single-item sales data is Check whether it has already been registered in the relay file. Then, when the registration has been completed, the collected single item sales data is added to the sales data of the corresponding single item code on the relay file. On the other hand, if it has not been registered, the collected sales data of individual products is additionally registered in the relay file.

Further, the file processor is configured to collectively transmit the contents of the relay file to the store processor through a communication line when a sales data collection request is issued from the store processor.

Here, the file processor is used for each POS.
It functions as a sales data processing device having means for collecting sales data of commodities registered for sale at the terminal and totaling the sales data by individual product code, and means for notifying the store processor of the result of totaling for each individual product code.

By the way, if the storage capacity of the relay file is set to a capacity sufficient to collect the sales data of all the products sold in the store, the storage capacity of each file processor becomes large and the system price becomes high. Inviting is not practical. Therefore, generally, the storage capacity of the relay file is reduced to reduce the price.

However, when the storage capacity of the relay file is reduced, the relay file may become full and the sales data of a new product cannot be additionally registered, so that the collected sales data may be lost.

Therefore, in order to avoid such a situation, conventionally, when sales data of a product whose individual product code is not registered in the relay file is collected with the free space of the relay file being equal to or less than a predetermined capacity, The single item code of the sales data is replaced with “0”, and the sales data of the product with the single item code “0” is registered in the relay file to prevent the loss of the sales data.

In this way, the process of substituting the single item code of a product with "0" and totaling the sales data is called misc process.

[0011]

However, in the conventional POS system using the file processor having the misk processing function, the relay file generated after the free space of the relay file becomes equal to or less than a predetermined capacity is a single item. All the sales data of the products for which the code is not registered will be aggregated as sales of the product with the individual product code “0”, so the store processor will later collect the contents of the relay file in each file processor and total the sales data for each product. However, at this time, there is a drawback that accurate sales total data by product cannot be obtained.

[0012] Therefore, the present invention is to provide a sales data processing device which enables the store control device to obtain accurate sales data for each product without increasing the storage capacity of the relay file. .

[0013]

SUMMARY OF THE INVENTION According to the present invention, a single-item master that presets and stores product information such as a single-item code, a product name, and a unit price set for each product, and cumulatively stores sales data of each product for each single-product code. A store control device having a file is connected via a first line, and a plurality of sales commodity registration terminals are connected via a second line,
A function to collect the sales data of each product registered for sale at each terminal through the second line and temporarily store it in the relay file, and the contents of the relay file through the first line in response to a collection request from the store control device. In the sales data processing device having the function of transmitting to the store control device, every time the sales data is collected from each terminal, a file checking means for checking whether the single item code of the collected sales data is registered in the relay file, and this file checking means When the registration is confirmed by, the sales data addition processing means that adds the collected sales data to the sales data of the corresponding single-piece code in the relay file, and the free space of the relay file when the unregistered is confirmed by the file inspection means Free space investigation means,
If the free space checking means confirms that there is free space above a predetermined capacity, the sales data addition processing means for additionally registering the collected sales data in the relay file and the free space checking means confirms that there is no free space above the predetermined capacity. Then, sales data transfer processing means for transferring the collected sales data to the store control device through the second line is provided.

[0014]

According to the present invention having such a configuration, every time the sales data of the product is collected from each terminal, it is checked whether or not the single item code of the collected sales data is registered in the relay file. Then, when the registration completion is confirmed, the collected sales data is added to the sales data of the corresponding single item code in the relay file. On the other hand, if unregistered is confirmed, the free space of the relay file is checked. Then, when it is confirmed that there is a free space equal to or larger than a predetermined capacity, the collected sales data is additionally registered in the relay file. On the other hand, when it is confirmed that there is no free space equal to or more than the predetermined capacity, the collected sales data is transferred to the store control device through the second line.

That is, the sales data of each product collected when the free space of the relay file is equal to or larger than a predetermined capacity is totalized and stored for each individual product code by the relay file.
Then, in response to a collection request from the store control device, the second
Is transmitted to the store control device through the line. On the other hand, the sales data of the new product collected when the free space of the relay file is equal to or smaller than the predetermined size is transferred to the store control device through the second line. Therefore, the store control device stores not only the sales data of the product collected when the free space of the relay file is equal to or larger than the predetermined capacity, but also the sales data of the product collected when the free space of the relay file is equal to or smaller than the predetermined capacity. Individual item codes are collected without being replaced with "0", and are summed up by individual item code by the individual item master file.

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

FIG. 1 is an overall view of a POS system according to this embodiment. This POS system includes a large number of sales commodity registration terminals, so-called POS terminals 1a and 1b, which are installed in each sales floor. , G
The file processors 2a and 2b are arranged in the groups G1 and G2, respectively, and the POS terminals 1a and 1b and the file processors 2a and 2b in the same group are connected to the communication line (hereinafter referred to as the second line). (Referred to as a communication line of 3) and 3b are connected in a closed loop. Also, the file processors 2a and 2b of the groups G1 and G2 are connected to a so-called store processor 4, which is a store control device that collectively manages the sales of the entire store, by a communication line (hereinafter, referred to as a first communication line) 5.

As shown in FIG. 3, the store processor 4 presets and stores the product information such as the individual product code, the name, and the unit price set for all the products sold in the store, and the sales of each product. A single-item master file 6 for accumulating and storing sales data such as points and amount of money for each individual item code is provided. Further, a relay file 7 for temporarily storing sales data of each product in each file processor 2a, 2b.
The system is constructed by providing a and 7b respectively.

FIG. 2 is a block diagram showing a main control circuit of the store processor 4. This store processor 4
Is a CPU (central processing unit) 40 as a control unit main body,
The CPU 40 has a ROM (Read Only Memory) 41 and a RAM (Random Access Memory) 42 as main storage units controlled by the CPU 40, and each file processor 2a is operated via the first communication line 5.
Communication interface 43 for controlling data communication with 2b
And peripheral devices such as keyboard 44, display 45, printer 46, HDD (hard disk driver) 4
7, controllers 44C, 45C, 4 for controlling FDD (floppy disk driver) 48, etc., respectively
6C, 47C and 48C, and the CPU 40 and RO
The M41, the RAM 42, the communication interface 43, and the controllers 43C to 48C are connected by a bus line 49 to form a control circuit.

The store processor 4 forms the single item master file 6 on the hard disk whose writing and reading of data is controlled by the HDD 47.

The store processor 4 is a RAM
42, as shown in FIG. 4, single-item sales data temporary buffer 4
The region 2a is formed.

FIG. 5 is a block diagram showing a main part control circuit of one file processor 2a. The file processor 2a includes a CPU 20 as the main body of the control unit and a C
ROM 21 and R as a main storage unit controlled by PU 20
Each POS terminal 1a having the AM 22 and controlling the data communication with the store processor 4 via the first communication line 5 and the first communication interface 23 via the second communication line 3a. It has a second communication interface 24 for controlling data communication with, and connects the CPU 20, the ROM 21, the RAM 22, and the first and second communication interfaces 23, 24 with a bus line 25 to form a control circuit. ing.

The file processor 2a is R
In the AM22, as shown in FIG. 6, the relay file 7a,
The registration number counter 26 that counts the number n of the single-item sales data (single-item code, number of sales, amount of sales) registered in the relay file 7a is formed.

Therefore, the CPU 20 of the file processor 2a is programmed so as to operate according to the control procedure shown in the flowchart of FIG.

First, ST (step) 1 receives data from the POS terminal 1a via the second communication interface 24, or ST2 receives data from the store processor 4 via the first communication interface 23. Wait until you receive.

When data is received from the POS terminal 1a in ST1, the type of the received data is checked and the corresponding task is executed. Here, when the single item sales data including the single item code, the number of sales, and the sales amount is received in ST3, the single item code area of the relay file 7a is searched in ST4, and the single item code of the received single item sales data becomes the above single item code area. Determine whether or not it has been registered (file inspection means).

When it is confirmed that the same single product code has been registered in ST5, the number of sales of the single product sales data received in the sales number area and the sales amount area corresponding to the same single product code of the relay file 7a is checked in ST6. And the sales amount are respectively added (sales data addition processing means).

On the other hand, when it is confirmed in ST5 that the same single product code is not registered, the count value n of the registration number counter 26 is incremented by "+1" in ST7. Next, at ST8, the count value n
Is the total number of records N that can be registered in the relay file 7a.
It is determined whether or not it exceeds the value N-1 obtained by subtracting one item. That is, it is checked whether or not the free capacity of the relay file 7a is equal to or larger than a predetermined capacity (for two sales data) (free capacity checking means).

When [n ≦ N-1] is satisfied, the relay file 7a still stores the new single item sales data 2
Since there is enough free space to register more than one case, ST
The single item sales data received as 9 is additionally registered in the relay file 7a (sales data addition processing means).

On the other hand, if [n> N-1] is satisfied in ST8, the relay file 7a is in a full state in which only one new single item sales data can be registered or no new data can be registered. The received single item sales data is transferred to the store processor 4 through the first communication line 5 by the action of the first communication interface 23 (sales data transfer processing means).

Incidentally, the CPU 40 of the store processor 4 which has received the single-item sales data is configured to temporarily store the received data in the temporary buffer 42a.

After that, the CPU of the file processor 2a
20 performs missk processing on the overflowed single item sales data. That is, in ST11, after replacing the single product code in the single product sales data with “0”,
In ST12, it is checked whether the single item code “0” is registered in the relay file 7a, and if it is not registered (in this case, there is one free space in the relay file 7a), the single item code “0”. Relay file 7
Add to a. If registered (in this case, the relay file 7a is full and there is sales data for the single product code “0” as the final record), the single product sales data received in the sales data for the single product code “0” Is added.

On the other hand, when the data from the store processor 4 is received in ST2, the type of the received data is checked,
Execute the applicable job. Here, if the received data is the sales collection request command in ST13, the contents of the relay file 7a are read and transmitted to the store processor 4 through the first communication line 5 by the action of the first communication interface 23.

Since the other file processor 2b has the same structure as the above file processor 2a, the description thereof is omitted here.

In the present embodiment thus constructed, the sales data of each product registered for sale at each terminal 1a of the group G1 is stored in one file processor 2a.
Are collected through the second communication line 3a, and are totaled by the individual code in the relay file 7a. Similarly, the sales data of each product registered for sale at each terminal 1b of the group G2 is secondarily processed by the other file processor 2b.
It is collected through the communication line 3b of and is collected by the relay file 7b for each individual product code.

However, for example, one file processor 2a collects unregistered single item sales data in the relay file 7a, and at this time, the count value n of the registration number counter 26 is larger than the total number N of records that can be registered in the relay file 7a. If it matches the value N-1 obtained by subtracting one item, the collected single-item sales data is immediately transferred to the store processor 4 through the first communication line 5 and stored in the single-item sales data temporary buffer 42a. Further, the single-item sales data is additionally registered in the relay file 7a with the single-item code replaced with "0".

Thereafter, when unregistered single-item sales data is collected again in the relay file 7a, the single-item sales data is immediately transferred to the store processor 4 through the first communication line 5 and stored in the single-item sales data temporary buffer 42a. At the same time, the single item code is replaced with "0" and added to the sales data of the single item code "0" in the relay file 7a.

This operation is performed by the other file processor 2
The same applies when unregistered single-item sales data is collected in the relay file 7b when the count value n of the registration number counter 26 in b is equal to or greater than the predetermined value N-1.

Then, after that, each file processor 2
When the store processor 4 sends a sales collection request command to a and 2b, the contents of the relay files 7a and 7b, that is, the sales total data for each individual product code is transmitted to the store processor 4.

Therefore, in the store processor 4,
Based on the contents of the relay files 7a, 7b collected from the file processors 2a, 2b and the overflowed single-item sales data stored in the single-item sales data temporary buffer 42, the cumulative total number of sales by individual item code in the single-item master file 6 By updating the area and the accumulated sales amount area, accurate total sales data by product can be acquired.

As described above, according to the present embodiment, when the free space of the relay files 7a and 7b is less than the predetermined capacity and the new single-item sales data cannot be additionally registered, the new single-item sales data generated thereafter is stored. Since data loss was prevented by transferring the data directly to the processor 4, even if the storage capacity of the relay files 7a and 7b is reduced and the system price is reduced, the store processor 4 can obtain accurate sales data for each product. Can be obtained.

Further, in this embodiment, the relay files 7a, 7
Misc processing is performed on the single-item sales data overflowing from b as in the conventional case, and the sales data of the single-item code “0” is totaled in the relay files 7a and 7b. Therefore, even if the overflow of the single item sales data due to a failure in the data communication between the file processors 2a and 2b and the store processor 4 cannot be transferred to the store processor 4, the sales data of the item is a single item code "0". It is secured as sales data for the product. Therefore,
The total sales data of the entire store can be acquired by the store processor 4 in the same manner as the conventional one.

When a failure occurs in the data communication between the file processors 2a and 2b and the store processor 4, the overflowed single item sales data is temporarily stored in another buffer and transferred when the failure is recovered. By doing so, the missk processing can be omitted.

In the above embodiment, the relay file 7a,
Although the method for checking whether or not the count value n of the registration number counter 26 is equal to or larger than the predetermined value N-1 has been shown as the free space checking means 7b, it goes without saying that the method is not limited to this. For example, if you omit MISK processing as described above,
Since it is not necessary to totalize the sales data of the single item code “0”, it is checked whether the count value n of the registration number counter 26 is a predetermined value N or more, and when the count value n is larger than the predetermined value, the relay files 7a and 7b are full. Overflow processing is sufficient.

In addition to the above, the present invention is applied to a system in which the POS terminal group and the file processor are only one system, each file processor in a system having three or more systems, and other various modifications without departing from the scope of the present invention. Of course it is possible.

[0046]

As described above in detail, according to the present invention, every time sales data is collected from each sales commodity registration terminal through the first line, the single item code of the collected sales data is already registered in the relay file. If it is confirmed that it is registered, the collected sales data is added to the sales data of the corresponding single item code in the relay file, and if unregistered is confirmed, the free space of the relay file is checked and there is free space above the specified capacity. When it is confirmed, the collected sales data is additionally registered in the relay file, and when it is confirmed that there is no free space more than a predetermined capacity, the collected sales data is transferred to the store control device through the second line. It is possible to provide a sales data processing device capable of acquiring accurate sales total data for each product by the store control device without increasing the storage capacity of the relay file.
