Abstract

PURPOSE:To easily grasp the changed contents of a unit price change in a file controller with respective POS terminals by equipping the POS system with a recording means to record and hold the changed contents when the above-mentioned unit price change is executed. CONSTITUTION:When a request for changing a unit price is transmitted from electronic cash registers 11-1n, the unit price of the piece of unit price changing goods before change, the unit price of the piece of the above-mentioned goods after change, and the time when a series of processing corresponding to the change request completes are recorded in a unit price changed data file 40 of a file controller 2. Thus the piece of goods, for which the unit price is changed, can be easily recognized, for example, by printing out the contents of the unit price changed data file 40. Moreover, since the unit price before change and the unit price after change are recorded at this time, the changed contents can be clear.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a POS system used in department stores, supermarkets, etc. that handle many products.

[Prior Art] In recent years, in department stores and supermarkets that handle a large number of products, electronic cash registers in each department are connected in a closed loop via a transmission line via one file controller, and the upper J file controller The host computer is connected to which store controller, and the store controller aggregates the sales data of each sales product registered for sale at each electronic cash register via the file controller to analyze sales for the entire store. POS systems are being introduced.

In such a POS system, the store controller is provided with an item file that stores item data such as name and unit price for each item code for all products in the store, and is also connected in a closed loop to the file controller. An FC single item file is provided that stores single item data of items that are frequently registered in each electronic cash register. Furthermore, each electronic cash register, ie, POS terminal, also has a local single item file that stores single item data of items that are frequently registered in that terminal. Therefore, when the single item code of a sales product is input from the keyboard of the POS terminal, the local single item file is first searched, and if single item data corresponding to the input code exists, sales registration processing is performed based on that single item data. . On the other hand, if the relevant single item data does not exist in the own local single item file, an inquiry is made to the file controller via the transmission path, the corresponding single item data is read from the FC single item file, and sales registration processing is performed. . Since the single item code reads out the unit price of the item, it is called a price look up (PLU) code.

By the way, when there is a change in the unit price of this conventional gpos POS system product, the corresponding unit price of the single item file in the store controller is changed, and the unit price data with the changed unit price is sent to the file controller and each PoS terminal, and the unit price for the FC single item is changed. Files and local single item files have been updated to the new unit price. Furthermore, if there is an abnormality in the line between the store controller and the file controller and a communication error has occurred, the unit price of the single FC file in the file controller can be changed using the keyboard of each PoS terminal. However, in this case, the unit price is only changed for the single item file for FC9,
The local single item file of each PoS terminal is not updated to the new unit price, and the file controller only stores the changed unit price in the single item file, making it difficult to know which item's unit price has actually changed. could not.

[Problem to be solved by the invention] As mentioned above, there are some problems with the conventional POS system of this type.
Therefore, when a unit price is changed by each PoS terminal, it is not possible to grasp the details of the change.

In addition, the unit price is changed by the store controller FC.
Since the local single item file of each PoS terminal is not updated to the new unit price, there was a problem that the unit price of the corresponding product in the FC single item file and the unit price of the applicable product in the local single item file did not match.

SUMMARY OF THE INVENTION Therefore, the present invention aims to provide a POS system that can record changes made to unit prices by each PoS terminal, and allows the changes to be easily understood.

In addition, the present invention can automatically update the local single item file of each PoS terminal to the new unit price when the unit price of the FC single item file is changed by each PoS terminal, and the correspondence between the FC single item file and the local single item file can be automatically updated. The aim is to provide a POS system that allows the unit price of products to be the same.

[Means for Solving the Problems] The present invention provides a file controller that has a single item file in which unit data such as the unit price of each product is set corresponding to the 111 item code of each product, and a sales registration process for each sales product. A POS system in which a plurality of PoS terminals that execute the above are connected via a transmission path, and a store controller that aggregates sales data of each sales product registered for sale at each PoS terminal is connected to the file controller. In the system, each PoS terminal is equipped with unit price change request means for requesting a change in the unit price of the product set in the single item file in the file controller, and the file controller
A unit price change processing means for changing the corresponding unit price of a single item file in response to a unit price change request from an OS terminal, and a unit price change data recording means for recording the unit price before change of the product whose unit price is changed by this processing means. It is prepared.

In addition to the above invention, when each PoS terminal stores a local single item file that stores the single item data of some products set in the single item file of the file controller, each PoS terminal The file controller is equipped with a local unit price change processing means for changing the corresponding unit price of its own local single item file in response to a unit price change request of the file controller, and the file controller changes the local unit price of each PoS terminal based on the unit price change of the single item file by the unit price change processing means. It is preferable to include a local unit price change requesting means for requesting a change in unit price of the product stored in the file.

Furthermore, each PoS terminal is equipped with a change result response means for responding to the file controller with the result of changing the unit price of the local single item file by the local unit price change processing means, and the file controller responds to each PoS in response to the unit price change request by the local unit price change requesting means. A change result recording means may be provided for receiving a change result response from a terminal and recording the change result for each PoS terminal.

Note that the unit price change data recording means may record the unit price after the change as well as the unit price before the change of the unit price changed product.

[Operation] With the present invention having such a configuration, when there is a request to change the unit price of a product from each POS terminal, the corresponding unit price of the single item file in the file controller is changed, and
The unit price before change of this unit price changed product is recorded. Therefore, it is possible to ascertain which product's unit price has been changed from this recorded content.

Additionally, when the corresponding unit price of a single item file in the file controller is changed in response to a unit price change request for a product from each POS terminal, a unit price change request for the local single item file is output to each POS terminal based on the change details. is,
In response to this unit price change request, the corresponding unit price in the local single item file of each POS terminal is changed. Therefore, the unit price of a single file in the file controller and each PO
The unit price of the local single item file on the S terminal matches.

By providing a change result response means and a change result recording means, each PO
Information on whether the corresponding unit price has been changed is grasped by the S terminal.

Moreover, by recording the unit price after the change together with the unit price before the change, the data becomes clearer.

It consists of a flag area 45 that stores a change flag (changed: 0, unchanged: 1) indicating for each register whether or not the unit price of the same product has been changed in the ECRtrJPLU files 81 to 8n. .

When there is a change in the unit price of a product in the POS system of this embodiment with such a configuration, the unit price of the product set in the PLU file 6 of the store controller 4 is usually rewritten, and then the file controller connected 2 and each electronic cash register 11-1n.
The data of the U file 6 is transmitted, and the contents of the FC PLU file 7 and the ECR PLU files 81 to 8n are updated.

However, if the communication line 5 that connects the store controller 4 and file controller 2 is down due to an abnormality, the PLU file data of the store controller, roller 4, file controller I, roller 2, and each electronic Since the data is not sent to the cash registers 11-1n, the electronic cash registers 11-12. You can change the unit price from here. That is, as shown in the flowchart of FIG. 5, the CPU 1 of the electronic cash registers 11 to 1-, l requests a unit price change from the keyboard 18 while the "manager" mode is selected by the mode switch 16. If you have the key data to do this, as ST (Step) 1, you can use the keyboard 18 to select the PL of the product whose unit price has been changed.
Wait for the U code to be entered. When the PLU code is input, the process waits for the changed unit price to be input from the keyboard 18 in ST2. Then, when the changed unit price is also input, a unit price change request message incorporating the PLU code and the changed unit price input as ST3 is edited,
It is sent to the file controller 2 via the transmission line 3. Thereafter, in ST4, a response from the file controller 2 is waited for, and when a changeable response indicating that the unit price change has been executed is received, the display unit 20 is driven and controlled in ST5 to display a display indicating that the unit price can be changed. Upon receiving a non-changeable response indicating that the change was not performed, the ST
6, indicating that the change is not possible, and ends this process.

On the other hand, when the CPU 31 of the file controller 2 receives the unit price change request message from the electronic cash registers 11 to 1rL, it executes the process shown in the flowchart of FIG.

In other words, in response to the reception of the message as 5TLI, F.
Search the PLU file 7 for C and find the PLU in the message.
Check whether a PLU code matching the code is stored.

If ↑σ is not written, the non-change response message is edited as S and TI2, and sent to the electronic cash registers 11 to 1n that have requested the unit price change, and this process is completed.

On the other hand, if there is a matching PLU code, the PL of the single 1d change data file 40 is set as 5T13.
The PLU code is stored in the U code area 41. Next, as 5T14, the unit price corresponding to the PLU code is read from the FC PLU file 7, and stored in the pre-change unit price area 42 of the unit price change data file 40 in correspondence with the PLU code input at 5T13. next,
As 5TI5, change the unit price corresponding to the PLU code in the FC PLU file 7 to the unit price in the message, and then
5TlB from the FC PLU file 7.
Read the rlitilt corresponding to the code and write 5T1
The code is stored in correspondence with the PLU code input in step 3.

Thereafter, the 5TL7 edits the non-change response message and sends the electronic cash register 1. to which the unit price change request was made.

Check whether a PLU code matching the code is stored.

If it is not stored, edit the non-changeable response message as 5T32, send it to the file controller 7, and end this process.

On the other hand, if a matching PLU code exists and it is 7, the own ECR PLU file 81 is set as 5T33.
The unit price corresponding to the PLU code of ~811 is changed to the unit price in the message, the changeable response message is edited as S, Ta2, and sent to the file controller 7, and this process is ended.

On the other hand, the CPU of the file controller 2 that sent the unit price change request message to each electronic cash register 11 to 1n
At step 31, a response from each electronic cash register 11 to 1n is waited for with the timer operating. If there is a response from any one of the electronic cash registers within the preset time, it will be possible to change the unit price of the applicable product set in the own ECR PLtJ file as 5T20. Text or own ECR
Check to see if it is an unchangeable message indicating that the corresponding product is not set in the J′rJPLυ file and the unit price has not been changed, and if it is a changeable message, correspond to the PLU code manually entered in 5T13. The change flag corresponding to the electronic cash register that received a response in the flag area 45 is reset to "O". On the other hand, in the case of an unchangeable message, the change flag corresponding to the electronic cash register that responded in the flag area 45 is set to "1".

Thereafter, the counter C is counted down by "-1" and a response from another electronic cash register is waited for. Then, each electronic cash register 1. ~11. If you receive a response from
The current time is read from the clock circuit 34 and stored in the time area 44 corresponding to the PLO code entered manually at 5T13, and this process is terminated.

On the other hand, if the set time of the timer elapses before responses from each of the 71 child cash registers 11 to ]n are received, the change flag corresponding to the electronic cash register that did not respond is set to "1", and the clock circuit 3 The current time read from is stored in the time area 44, and this process ends.

As described above, in the POS system of this embodiment, when a request is made to change the unit price of a certain product by operating a key on the keyboard 18 of the electronic cash register 11 when the communication between the store controller 4 and the file controller 2 is down, FC formed in file controller 2
The unit price of the product in the PLU file 7 is changed, and the unit price before and after the change of the product are recorded in the unit price change data file 40 in the file controller 2 in correspondence with the PLU code of the product.

Additionally, a request is made from the file controller 2 to each electronic cash register 11 to 1n to change the unit price of the corresponding product, and in response to this request, Kanako stores the single item of the corresponding product in her own ECR PLU file. In the expression cassonyu register, the unit price in that file will be changed.

At this time, the electronic cash register that has completed the jli price change returns a change-permitted response to the file controller 2, and the electronic cash register that has not changed the unit price returns a change-unable response. Then,
In the flag area 45 of the change data file 40, the change flag of the electronic cash register for which the response was changeable is reset to "0", and the change flag for the electronic cash register for which the response was not changeable is reset to "1". ” is set. Additionally, the change flag for electronic cash registers that did not respond within the set time due to power outage, etc. will also be set to “1”.
``Sera!・is done.

Therefore, according to this embodiment, when there is a request to change the unit price from the electronic cash registers 11 to 1n,
File controller 2 unit price change data file 40
Since the unit price before the change, the unit price after the change, and the time when a series of processes in response to the change request were completed are recorded for the unit price changed product, for example, by printing out the contents of the unit price change data file 40, the unit price can be changed. Products that have been changed can be easily recognized. Furthermore, since the unit price before change and the unit price after change are recorded at this time, the content of the change is clear.

In addition, the unit price in the FC PLU file 7 is changed, and the unit price in the ECR PLU table of the electronic cash register in which the single item data of the corresponding product is stored is also changed, so that the unit price of the same product is changed from the FC PLU file 7.
The problem of mismatch between the table 7 and the ECR PLU tables 81 to 8n is eliminated.

Furthermore, in response to the 111 price change request from the file controller 2, the electronic cash register that changed the unit price of its own ECR PLU file returns a change permission response, and this causes the file controller 2 to file the unit price change data file. The change flag for the corresponding electronic cash register of 40 is reset to 02, and the change flag for the other electronic cash registers is reset to "1".
Therefore, based on the state of this change flag, it is possible to distinguish between electronic cash registers for which the unit price has been changed and electronic cash registers for which the unit price has not been changed.

In the above embodiment, a case has been described in which the unit price after change is recorded together with the unit price before change of the unit price changed product, but even if only the unit price before change is recorded, the effects of the present invention can be sufficiently exerted.

Furthermore, in the above embodiment, the change flag of an electronic cash register that did not receive a response within the set time was set to "1". It can be distinguished from the existing electronic cash register. It goes without saying that various other modifications can be made without departing from the spirit of the invention.

[Effects of the Invention] As detailed above, according to the present invention, when a unit price is changed by each POS terminal, the change can be recorded and the change can be easily grasped in a POS system. can be provided.

Further, according to claim 2, when the unit price of the FC single item file by each POS terminal is changed, the local single item file of each POS terminal can also be automatically updated to a new vehicle.
It is possible to provide a POS system that can make the unit price of the corresponding product the same in the FC single item file and the local single item file.

Furthermore, according to claim 3, the POS terminal on which the unit price change of the local single item file was performed and the P
It is possible to provide a POS system that can easily identify OS terminals.

Moreover, according to claim 4, there is an effect that the details of the unit price change are made clear.
