DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for responding to a loss of POS transmission data, and more particularly to a method for responding to a loss of POS transmission data in which data is retransmitted from a POS terminal using loss management and a difference check. .

[0002]

2. Description of the Related Art A conventional POS terminal of a food / restaurant store system is installed in an environment where the unit price is low and the number of transactions is large. The maximum number of POS operated is 200
It is difficult to transmit all the data to the connected upper store computer in real time because of the load. Therefore, in the case of cash transaction by button preset, a method is adopted in which the summary is stored in the memory of the POS and the summary data is transmitted to the store computer together with the settlement item at the time of settlement.

[0003]

The store computer is connected to the FEP and the host computer in the central center, where the total value of the real data and the summary data and the amount of the clearing item are stored in the PO for each terminal number.
The host prints out the S terminal total list, and checks the occurrence of the difference the next day at each store accounting.

[0004] Data transmission may not be performed properly and may be lost due to a line failure between the POS and the store computer or a failure on the store computer side.

When the above phenomenon occurs, the difference is printed out as a difference in the POS terminal total list. After investigating the cause, the transaction corresponding to the difference is identified by a POS journal or the like, and correction registration is performed at the correction register of each store.

A great deal of man-hours are required for data recovery.

[0007]

According to the present invention, there is provided a method for responding to a loss of POS transmission data according to the present invention. A POS terminal having a function of requesting retransmission of missing data from an upper store computer or retransmitting missing data when residual data exists. ,
Terminal master update to manage missing and duplicate POS transaction numbers, transaction data transmission to check the difference between the settlement data and the amount of real data + summary data, and a resend request to the POS terminal when they issue a request And a POS return control for transmitting the POS.
A store computer connected to the terminal.

[0008] The method of responding to the loss of POS transmission data according to the present invention is as follows: (A) Entering a code of a product number / class, using a gait rate / amount, entering a gift statement, or paying with a prepaid card. In the case of credit transactions, etc., send the sales data in real time, send cash sales with other button presets as summary data at the time of settlement to the store computer, and if a residual log occurs offline or from the store computer A POS terminal for retransmitting the relevant data when a retransmission request is made;
(B) The log data transmitted from the POS is directly
Means for outputting to S log file; (C) means for managing missing / duplicate transaction numbers for each terminal; (D) means for updating part number class, master and part number parameter files; Means for creating a file, a transaction statement data transmission file, and checking the difference between the total value of real data + summary data and the amount of settlement data from the transaction statement data transmission file,
It is provided with.

[0009]

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a real online configuration diagram showing one embodiment of a method for coping with a loss of POS transmission data according to the present invention.

[0011] When sales data or the like is input from the POS terminal 1, the input data is written into a POS log 21 by the POS data control 11 and passed to the terminal master update 12. Terminal Master Update 1
2, the terminal master 23 is updated. Similarly,
The part number class master 24 and the part number parameter 25 are updated in the part number class master update 13, and the transaction data transmission 14
An in-house transaction data transmission file 26 and a transaction statement data transmission file 27 are created, and the data is transmitted to the host computer by the host interface transmission 15.

The summary data is transmitted together with the settlement data transmitted from the POS.

POS terminal 1 and store computer 2
If transmission loss occurs between the POS terminals 1,
Since the missing log is managed, retransmission processing is performed. If there is a residual log on the next business day, the log is transmitted to the store computer 2 as correction data.

When the settlement is executed, the power of the POS terminal 1 is automatically turned off. Therefore, when the settlement data comes to the terminal master update 12, the missing transaction number is checked, and the POS return control 17 sends the POS terminal 1 to the POS terminal 1. Request retransmission of missing data.

When settlement data is sent to the transaction data transmission 14, the transaction reference data transmission file 27 is referred to, the difference is checked, and the missing transaction number is searched.
The return control 17 requests the POS terminal 1 to retransmit the missing data.

If the settlement data has not been received from the POS terminal 1 in the previous day's data to the store computer 2 on the next day, a retransmission request is similarly sent to the POS terminal 1 and the settlement data + missing data is transmitted.

[0017]

As described above, according to the present invention, the management of missing POS data by updating the terminal master,
Missing data management and clearing data by sending transaction data,
The difference between the real data and the summary data is checked, and when there is missing data, the effect of reducing the missing data is achieved by the process of retransmitting the missing data to the POS by the POS return control.

[0018] As a result, the difference between the terminal total list of the host computer output due to the missing data, the accounting process of the accounting, and the process of correcting and registering the correction register are reduced as much as possible.

Claims (2)

(57) [Claims] 1. A POS terminal having a function of requesting retransmission of missing data from a high-order store computer or retransmitting missing data when residual data is present, a terminal master update for managing missing and duplicate POS transaction numbers, The POS has transaction data transmission for checking the difference between the settlement data and the amount of the real data + summary data, and a POS return control for transmitting a retransmission request to the POS terminal when they issue a request.
P with store computer connected to terminal
How to handle missing OS transmission data. 2. When sales data or the like is input from a POS terminal, the input data is written to a POS log by POS data control, the terminal master is updated by updating the terminal master, and the part number class master is updated by updating the part number class master. , Update the part number parameters, create a transaction data transmission file and a transaction statement data transmission file by sending transaction data, send the data to the host computer by sending the host interface, and clear the summary data from the POS When the POS terminal and the store computer transmit the data, they are transmitted together. If the transmission is lost, the POS terminal performs the missing log management. If there is a log, The POS terminal is automatically turned off when clearing data is sent to the POS terminal. When the clearing data comes to the terminal master update, the missing transaction number is checked and the POS terminal returns the missing data to the POS terminal. If a resend request is made and clearing data comes to the transaction data transmission, the transaction details data transmission file is referenced, the difference is checked, the missing transaction number is searched, and the PO
Requests retransmission of missing data to S terminal, sends resending request to POS terminal the next day if no clearing data has been received from POS terminal to store computer the previous day, and transmits clearing data + missing data. POS transmission data is lost.
