Abstract

PURPOSE:To change prices in a short time in a POS system of a central PLU system by providing a rewriting table for commodity management data to a PLU controller. CONSTITUTION:An operator supplies a code number, the changing item and the contents of commodities desired to change its price through a host device 5. These input data are stored successively with plural commodities into a table 30 provided in a PLU controller 11. When the input is through with the changing data on all commodities to be changed, a data rewriting command to be given to a memory medium 21 from the table 30 is delivered to the controller 11 from the device 5. Thus the rewriting data supplied to the table 30 are transferred to the medium 21. At the same time, the changed prices of the corresponding commodities are written on the medium 21. In such a way, the prices of commodities can be changed and rewritten in a short time.

Description

[Detailed Description of the Invention] [Summary] A POS system that handles product information is equipped with a control unit like a central FLU controller in the system.
Some devices are designed to send back necessary answers to inquiries about product information such as price and product name from a POS terminal. In a POS system that employs such a central FLU method, for example, there may be cases where it is desired to change the price of some products depending on the time of the day, such as morning or afternoon. This is to realize a maintenance method that allows management and other maintenance to be performed all at once in a short period of time.

[Industrial application field]

The present invention is a product information maintenance method for a P0.5 system, and in particular, product information maintenance that allows changes in product information such as product prices managed by a control unit to be processed at once for multiple items. It is related to the method.

[Conventional technology]

At mass retail stores such as Dehart and supermarkets, the product numbers, product names, AA prices, etc. of the products handled are centrally managed at the center, and terminals *m (referred to as J! lower PO5 terminals) are placed at each sales floor to operate cash registers. The so-called central P
There is a POS system that employs the LU (Price Look Up) method, and the basic configuration of such a method is shown in FIG.

The central FLU-based POS system shown here uses an FL connected to a host device 5 (indicated by SLP in the diagram) that aggregates sales data and manages PO8 terminals.
U controller l (hereinafter simply referred to as controller),
Multiple PO3 terminals (1
It is assembled by ゜2,...,N)4. An external storage medium such as a floppy disk 2 that stores data such as unit price and product name is set in the controller 1, and various signals and data are transmitted between the controller 1 and the PO5 terminal 4. The controller 1 and the host device M5 are connected by a line 6. In addition, the controller 1 has a FLU function, that is, a function to accept and accept product price adjustment (furthermore, product name adjustment, which is an HLU function) from the PO5 terminal, and also has a function to accept and accept product price adjustment from the PO5 terminal. details are collected as data and recorded on the floppy disk 2, which is an external storage medium, while similar data is transferred to the host device 5 and aggregated. In such a POS system, when performing FLU maintenance, for example, changing the price of a single item, conventionally, as shown in FIG. It was changed for each product by typing. After the price of the product is changed, data regarding the new price is sent back from the controller 1 for price adjustment from the PO5 terminal 4, and the operator operating the POS terminal 4 conducts transactions based on the new price. can be done.

[Problem that the invention seeks to solve]

However, in the maintenance method of such a conventional POS system, the single item price information 2a is changed for each item on the floppy disk 2 set in the controller l. There was a problem that when the number of managed products that required a price change reached a certain amount, the change operation took too long.For example, from 3:00 p.m. When a decision is made to reduce the price of a product, if the operator manually changes the price of each product subject to price reduction, by the time the price of the last product is changed, the
It's past 3 o'clock and there is a risk of confusion at the cash register.

The present invention was made in view of these conventional problems, and its purpose is to enable central FLU type POS systems to handle maintenance such as price changes for managed products all at once, and to change prices in a short time. The objective is to provide a maintenance method that can perform the following tasks.

[Means for solving problems]

In order to achieve the above object, the present invention provides a table for rewriting product management data in the FLU controller in order to maintain product information, and sets this table so that data can be input from an upper or lower device. , the configuration is configured so that rewrite data is input for each managed product stored in the storage medium, and after all the rewrite data has been input into the table, these rewrite data are collectively assigned to the storage medium. The gist of this is that the information is transferred to the product item that is displayed.

[Effect]

The operator uses the host device to input the code number of the product for which the price is to be changed, the item to be changed, and the details (for example, changing the unit price of the product). This input data is sequentially stored for a plurality of products in a table provided in the PLU controller.

When change data (ie, rewrite data) has been input for all products that require change, a data rewrite command from the table to the storage medium is then output from the host device to the FLU controller. As a result, the rewritten data input to the table is transferred to the storage medium, and the changed price is written in the area of the corresponding product item in the storage medium. Therefore, the process of rewriting the changed price can be performed in an extremely short time, and the rewriting process does not take a long time and cause confusion at the cash register.

〔Example〕

1 to 4 are diagrams showing the configuration and operation of an embodiment of a PLO controller for executing the maintenance method of the present invention. Of these, FIG. 1 is a block diagram showing the principle of the above embodiment. Controller 11 according to this embodiment
is connected to the higher-level device 5 via a line 6, and is connected to the PO3 terminal 4, which is a lower-level device, via a line 3.

This controller 11 has a built-in storage medium or a floppy disk 21 can be set as an external storage medium. Data on various products is stored in this storage medium, and price inquiries and other requests from the PO8 terminal 4 can be sent to the controller 11. It is now possible to respond to questions about product names. Furthermore, a table 30, which is a storage section, is installed within the controller 11. This table 30 is used to store and hold rewrite data for rewriting the data on the floppy disk 21 when changing the price of a product to coincide with the start of a special sale, for example.
15 or from the PO8 terminal 4. Upgrade the rewrite data input! When starting from i5, first set table 30 to write mode using line 6b.

Next, rewrite data is input through the line 6a.

On the other hand, when inputting rewritten data using the PO5 terminal 4, the table 30 is first put into write mode using the line 3b, and the rewritten data is inputted primarily through the line 3a. By inputting these rewritten data, the product names and prices to be rewritten sequentially from the top are written in the table 30. When the writing to the table 30 is completed, the rewritten data is temporarily held in the table 30. When the 0th sale starts, the data rewriting signal is inputted to the table again from the line 6b or 3b, and the rewritten data is written all at once. It is then transferred to the corresponding section of a predetermined file (bargain file 29) in the floppy disk zl.

A more detailed configuration of the controller 11 is shown in FIG. 2. The controller 11 includes a main CPU 12 and three sub-CPUs connected to the main CPU 12 via interfaces 16, 17, and 18 to a bus 19. We are prepared. The sub CPU is connected to the controller 11 and the host device 5.
