Abstract

PURPOSE:To improve the efficiency for sales and registration at a terminal by providing a subordinate price index file to each register to store the price index data on articles having high sale frequencies. CONSTITUTION:When a price index PLU key on a keyboard 7 is pushed, an article code is called into an RAM21. Then a subordinate PLU file 31 is retrieved to search the PLU on the article code equal to the desired one. If the desired article code exists, the corresponding PLU data is transferred to PLU processing buffer 32. The buffer 32 performs the sale registration processing by means of the link department, the unit price, the article name, etc. within the PLU data. Then the unit price, the total amount, the quantity, changes, etc. are displayed 12 and printed 22. In case the desired article code does not exist in the file 31, an inquiry text including the article code, etc. is produced by a transmission buffer 33. Then the code is stored in an idle area of the file 31 via a terminal control part 3.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a POS system, and particularly relates to a POS system.
The present invention relates to a POS system having a sub-PLU file in the valley terminal in addition to the U file.

[Technical background of the invention and its problems]

At stores, supermarkets, etc. that handle a large number of products, POS (Paint of 5a) is used to manage sales and inventory using product codes assigned to each product.
les) system is beginning to be adopted.

Such a POS system, for example, has multiple terminals installed at a sales floor, all of which are electronic cash registers (hereinafter abbreviated as registers).
It is connected to the lJ 11i1 part, and each barcode detector is equipped with a barcode detector that reads all barcodes that indicate product codes such as the JAN code found on valley products, or a PLU that can be manually operated by key operation. A key is provided. In addition, the unit price and product name for each product yaw 1-4 are stored in the terminal control unit fCPLU (P
riceLookUp) file is provided.

In such a POS 7 system, when the product code of a sold product is inputted to a register placed in each sales floor using a barcode detector or key operation, this register sends a message to the terminal control unit that indicates the product code corresponding to the product code. Arrange PLU data such as unit price and part name. The terminal control unit 1) searches the LU file, reads the PLU data corresponding to the applicable product code, and sends it to the registered register. The register then registers the sale of the product based on the sent PLU data.

Then, the sales registration data such as the number of sales items is sent to the terminal control unit, and based on this sales registration data, the terminal control unit updates the registration data indicating the seller, etc. of the PLU data of the corresponding product in the PLU 7 isle. do.

=5- However, in a POS 7 system with such a configuration, a large number of registers are connected to one terminal control unit, and each time a sales registration is made at each register, the upper register is sent to the terminal control unit. Inquire about PLU data. Therefore, if many products are sold out in a short period of time, the above inquiries from the valley register may overlap in time.
The amount of processing work such as searching and reading PLU files in the terminal control unit increases, and the time for returning each PLU data to each v) station is delayed. As a result of 7, at the register, the response time from key operation to the output of the sales registration result on the electronic display or receipt increases, and there is a risk that the work efficiency of sales registration work will decrease. As the number of installed registers increases, the response time described above increases dramatically, sometimes requiring a wait of several seconds, and in the worst case, the permissible response time may be exceeded and sales registration may not be possible.

In addition, in order to eliminate all of these problems, the number of registers connected to one terminal control unit must be reduced to 6-j! 9, the capacity of the transmission line between the terminal control unit and each register had to be increased, resulting in an increase in equipment costs.

[Purpose of emitting ψ]

The present invention was made based on the above circumstances, and its purpose is to provide a Zabu PLU file that stores PLU data of products that are frequently sold in Tanishi Minosta, so that the terminal PO that can completely reduce the time required for the control section, improve the work efficiency of sales registration work at the valley register, and reduce equipment costs.
The goal is to provide an S system.

[Summary of the invention]

The present invention applies to each terminal (register).
A Zabu PLU file with a smaller capacity than the center PLU file that stores PLU data is provided, and when registering a product, if the PLU data corresponding to the sales registration product is stored in the Zabu PLU file, sales are registered based on this PLU data. , is not stored in the above sub-PLU file, and if there is free space in the above sub-PLU file, the terminal city IJ some center I)L[J
After the corresponding PLU 7'-data of the file is stored in the above-mentioned free area, sales are registered based on this PLU 7'-data.

In another invention, the PLU data of a sales registered product is not stored in a sub-PLO file, and this sub-PLO file is
If there is no free space in the LU file, the sub PLU
All the PLU data in which the registration data indicating the sales quantity, etc. in the 7 isles indicates the minimum price are deleted, and the corresponding PLU data of the center PLU 7 isles is stored in the desired area after this deletion.

A transmission buffer 33 for sending to the terminal 3 and a reception buffer 34 for receiving all PLU data returned from the terminal control section 3 are stored. Furthermore, as shown in FIG. 5, the pre-loaded PLU file 31 contains a product code for each valley product.

In the embodiment, an area is set in which PLU data consisting of a link department, a threshold product name, registration data indicating the registered sales quantity of one product, and a sales amount can be stored in 100 types of product cases. Also, P that can be stored in this Zabu PLU file 31
"+VIAX-Number of PLUs" indicating the maximum value of LU data
Also, "PI, U setting number" indicating the number of PLU data actually stored at present is stored.

On the other hand, the center PLU of Terminal City 1" 1 Kanobu 1 (3)
As shown in FIG. 6, File 2 is a P
LU data is stored for each product.

However, this center PLU file 2 stores PLU data of all products registered for sale at each sales floor and each reno star 1. In the example, P of 500 types of products
LU data is stored.

In the POS system configured as described above, when registering a product for sale using the valley register l, the CPU
The operation of step 4 will be explained using the flowcharts of FIGS. 4 and 7.

First, the gear lasher sets the control key 1) provided on the front of the resto star 1 to the "registration" position. next,
Product code f of the product to be sold Enter by operating the barcode detector or the number keys 8 on the keyboard 7. Then, when the keyboard 70 PLU key 10 is pressed, the product code is read into the RAM 21. When called into the Vi 21, the sub PLU file 3 is searched to find PLU data having the same product code as the above product code. Then, if the corresponding product code exists, this PLU disk will be processed as PLU! Transferred to the buffer 32, this PLU processing buffer 32 executes sales registration processing using the linked department, unit price, product name, etc. in the PLU data, and the resulting unit price 9 total amount and sales quantity , change 2
The information is displayed electronically on the display unit 12 through the display circuit 28, and is printed out on a receipt by the printer 22 through the printer drive circuit 23. Note that the product name may be printed out on the receipt.

Then, the sales registration data indicating the sales amount is sent to the entire sending buffer 33, and the sending buffer 33 sends the product code,
A sales registration 1'EXT containing the sales quantity is created and sent to the terminal control unit 3 via the output port 25 + transmission line 4 13-. The terminal control unit 3 searches all center PLU files 2 for PLU codes that have the same product code as the product code of the above sales registration 'IKT, and adds the sales registration data in the sales registration T EXT to the registration data of the corresponding PLU code. At the same time, the sales amount of the product is also updated. On the other hand, the sales registration data is sent to the sub-PLU file 31, the registration data and sales amount of the corresponding PLU data are also updated, and the sales registration of this product is completed.

In addition, when the key is P of -do 7 and the σ key 10 is pressed, RAM 2
If the product code called in 1 does not exist in this PLU 7-r file as a result of searching the sub-PLU file, the transmission buffer 33 sends the product code and the timing TEXT containing the own reno star number money. is created and sent to the terminal control section 3. FLAGil is set to indicate that the timing has been reached at the same time. The terminal control unit 3 stores the PLU code having the same product code as the product code of the above-mentioned makeshift TMXT in the center PLU file 214.
- Search for the corresponding PLU data and send it to the register 1 indicated by the register number in TEXT via all the transmission lines 4. In register 1, transmission line 4. All input ports 26 are connected to the input buffer 34 in the RAM 21.
After confirming that all of the PLU data stored in the PLU data is the requested PLU data, it is transferred to the PLU processing buffer 32. Then, the PL transferred in this processing buffer 32
Register sales of products based on U data. Then, the sales registration data is sent to the center PLU file 2 of the terminal control unit 3 in the same manner as described above, and the registration data and sales amount that were stored in the PLU processing buffer 32 before the transfer of the PLU data are deleted. The newly generated sales registration data and sales amount are stored.

Next, after confirming that FRAG = 1 i, which indicates that the time has been met, set the "Number of PLU settings" and "MAX ・P" shown in Figure 5.
Compare the ``Number of LUs'' and check that the ``Number of PLU settings'' is max.
・If PLU i” has not been reached, there is free space in sub PLU file 3, so the previous i
i All registered PLU data in the own PLU processing buffer 32 is transferred and stored, and the above "PLU setting number #total 1"
Only count up. Then, the FLAG is returned to O, and the sales registration of this fishing item is completed.

Furthermore, "PLU fixed value" and "MAX - PLU number"
When they are equal, there is no free space in the sub PLU file 31. In this case, all the registered data of each PLU data in the sub-PLU 7 isles 31 are compared, the PLU data for which this registered data shows the minimum value is deleted, and the registered data in the PLU processing buffer 32 is stored in the free space after this deletion. Transfer and store the completed PLU data. And FLAG
i Return to O and finish sales registration for this product.

In a POS system with such a configuration, the sub-PLU file of each register 1 contains P of products that are frequently registered for sale.
By storing all LU data, own sub PLU
When registering the sales of parts corresponding to PLU data stored in a file, there is no need to adjust the PLU data to the terminal system a section 3, and as a result, the terminal control section 3 also transfers the PLU data to the register 1. There is no need to send it. Therefore, for products with a high sales registration frequency, Tanishinosta only needs to send sales registration data to the center PLU file of the terminal control unit 3, which reduces the amount of processing work such as searching and reading PLU files in the terminal control unit. can be significantly reduced. As a result, in register 1, display section 1
2 or 7 Since it is possible to shorten the response time until the time when the sales registration result is output on the receipt sent out from the ticket issuing port 13, the overall work efficiency of sales registration work can be greatly improved. can.

In addition, it is only necessary to set the PLU data of the product with the highest sales volume in each Zosta 1 installed in each sales floor in the sub-PLU file 31 of all registers 1, so the sub-PLU file 31 of each register 1 The total capacity can be set to the minimum required. Therefore, by providing a small-capacity 17-7" PLU file 3 in the valley register 1, it is possible to greatly increase the number of registers that can be connected to one terminal control unit 3. Overall equipment costs can be reduced.

Furthermore, in the embodiment, when there is no free space in the sub-PLU file 31 of register 1, the smallest PLU data of the registered data of PLU data in this sub-PLU 7 isle 3 Delete the products with few sales registrations and create a new PLU 7” data from the center PLO file 2 in this sub-PLU file 31.
I am trying to store it in . Therefore, since the sub-PLU file 31 always stores PLU data of products with high sales registration frequency, it is possible to further reduce the number of times PLU data is sent from the register 1 to the terminal control unit 3. . As a result, it is possible to further improve the above-mentioned effects.

Incidentally, since it is not necessary to set the sub-PLU file of each register 1 in advance, the operation before the start of sales does not become particularly complicated.

Note that the present invention is not limited to two consecutive embodiments. In the embodiment, when sub-PLU file 3 of register 1 runs out of free space, all the PLU data with the least registered data is deleted and new PLU data is stored there, but when there is no free space in sub-PLU file 3, When the area runs out, the center PL will be sent to the center PL as in the conventional POS system for each sales registration of a product that is not stored in the Zabu PLU file 31.
Even if PLU 7J-2 is sent from U file 2, the effects of the present invention can be sufficiently achieved.

〔Effect of the invention〕

As explained below, according to the present invention, by providing a sub-PLO file for storing all PLU data of frequently sold parts in each terminal,
It is possible to reduce the number of times PLU data is transferred from each register to the terminal system (i11) section where the center PLU file is provided.Therefore, the search and readout time for the center PLU file in the terminal control section can be shortened, and the sales at each register can be reduced. It is possible to improve the work efficiency of registration work and to reduce the equipment cost of the POS system as a whole.
