Description

TECHNICAL FIELD OF THE INVENTION The present invention relates to a unit price data processing method in a weighing and pricing machine connected to a host computer as an in-line system.

Technical Background and Problems Conventionally, in an in-line system in which a large number of weighing machines are connected to a host computer, there is a semi-center specification in which unit price data that changes daily is set in advance on the host computer side. That is, the host computer has a ledger file that stores unit prices for each product number and a production file that is used temporarily, and stores daily unit price data in this production file. Therefore, the unit price data stored in the production file is different from the unit price data for the same product number stored in the ledger file, and even for products with the same product number, the unit price data may differ from store to store. The ledger file and the production file that have stored the necessary data in this way are retrieved with priority given to the contents of the production file when a call is received from the weighing and value marking machine.

However, in such conventional methods,
When changing the unit price data stored in the production file, the previous data must be deleted and cannot be used again. Moreover, since the data itself is constantly being processed, numerical errors tend to occur.

OBJECTS OF THE INVENTION An object of the present invention is to provide a method for processing unit price data in a weighing and pricing machine, which facilitates processing of preset data and prevents errors in numerical values.

Summary of the Invention The present invention includes control information indicating whether the unit price data can be used or not, which is stored in the data file of the host computer, so that the data can be selectively used while the unit price data is saved. Moreover, the structure is such that there will be no mistakes in numerical values during the selection operation.

Embodiments of the Invention First, the host computer 1 has a product master file 2 as a register file and a production file 3. This product master file 2 contains
It is used as a PLU (a so-called price lookup in which the unit price and other data corresponding to the product code are retrieved by inputting it) memory, and all unit prices are stored in advance. The production file 3 is used to temporarily store daily unit prices and store data that differs from store to store.

Connected to such a host computer 1 are an extremely large number of weighing value marking devices 4 as terminal devices. These weight value marking machines 4 each have an inline sending buffer 5 and an inline receiving buffer 6.
It has a built-in. Further, the weighing value marking machine 4 is provided with a weighing label registration memory 8 of a PLU memory 7. This PLU memory 7 stores exactly the same data as the product master file 2.

In such a configuration, unit price data is stored in advance in the product master file 2 and the production file 3 on the host computer 1 side. In this case, product master file 2 contains
All unit price data corresponding to product codes are stored as standard data. Further, the production file 3 stores daily unit price data for the current day and data of values that differ from store to store. The contents of this data are specifically shown in FIG. In the drawings, STX is the start of text, EM is the end mark, and ETX is the end of text. And N indicates any numerical value, especially,
A distinctive feature is that FLAG exists in the unit price column. This FLAG is control information and is "0"
"1" indicates that the unit price can be used, and "1" indicates that the unit price cannot be used.

The operation of the PLU process will now be explained based on FIG. First, Process A is performed on the condition that the weighing mode is not in place, the total key is not pressed, the asterisk key is pressed, and the unit price temporary change mode is not in effect. This process A is a process for transferring unit prices and the like from the PLU memory 7 of the weighing value applicator 4 to the weighing label registration memory 8.
Next, it is determined whether or not it is semi-center inline, and if it is semi-center inline, processing B is performed.
will be held. This process B is to transfer the PLU code and store code to the inline transmission buffer 5 for the weighing value marking machine 4 in use. When this process B ends, process C is performed. This process C is for inline processing and transferring the contents of the production file 3 of the host computer 1 and the number of packs to the inline reception buffer 6. When this process C is completed, a check is made to see if the data contains control information. Here, when the control information is "1", process D is performed,
When it is "0", the data in the product master file 2 of the host computer 1 is used as is. Thus, process D is to transfer the contents of the inline reception buffer 6 to the weighing label registration memory 8. Therefore, the data used for pricing is replaced by the daily unit price of the production file 3 of the host computer 1.

Effects of the Invention The present invention has a production file that stores not only standard unit price data but also daily unit price data when establishing a PLU on the host computer side as described above, and at this time, Since control information is added to indicate whether the data can be used or not, there is no need to change numerical values when processing daily data, etc. This makes the operation easier and prevents data errors. This has the effect of not causing any problems.

Claims (1)

[Claims] 1 In an in-line system with semi-center specifications, in which the unit price of the PLU is transmitted from the host computer by calling the PLU from the weighing machine side, when unit price data is received from the host computer, the control information included in the unit price data If it is usable, the unit price data of the transmitted production file is used; if the unit price data is not usable, the unit price data of the ledger file preset in the host computer is used. unit price data processing method.
