Description

Detailed Description of the Invention [1] Technical Field of the Invention The present invention provides a master-slave POS data collection system in which a master POS device and a slave POS device are able to collect data that is not tied to each other at the same time when collecting payment data. Regarding collection methods.

■ Background of the Technology Conventional POS systems usually consist of a data collector, a floating point recorder, and a plurality of POS terminals, and data from each POS terminal is regularly collected by the data collector.

This data was recorded on a floating recorder. 1st
The figure shows a schematic configuration of a conventional POS system. In the figure, 1 is a data collector, 2 is a floppy recorder,
3 to 5 indicate POS terminals. The data collection process is performed as follows.

■ POS terminal where you want to start payment, e.g.
From S3, a “settlement request” message is sent to the data collector 1. - When the data collector 1 receives the "accounting request" message, it returns a "acceptance OK" message to the POS 3 if the data collector 1 can accept the request.

- When the POS 3 receives the "acceptance OK" message, it executes the editing process of the payment data and sends the total data to the data collector 1.

The data collector 1 stores the received total data on the floppy disk of the floppy recorder 2, and simultaneously prints out the data in synchronization with data reception.

As an advanced version of the POS system described above, the data collector is replaced by a POS terminal, and one master P
An OS terminal (hereinafter simply referred to as master POS) and multiple slave POS terminals (hereinafter simply referred to as slave POS terminals)
There is a system called OS.

In this case, the master POS performs a data collection function as a data collector, and also performs processing functions such as product sales, deposits, and payments at the same time as the slave POS. However, in the above system, the mask POS and slave POS maintain an interactive relationship and perform payment processing and transfer after mutual confirmation, in order to prevent data transfer omissions and other erroneous processing. is configured to do so.

Therefore, when the slave POS enters the checkout state and the master POS responds and enters the checkout data collection state, both POSs are removed from customer service at the same time, which has a negative impact on sales when the store is crowded. This was a problem because it could also cause problems.

OBJECTS OF THE INVENTION An object of the present invention is to provide a POS system composed of a master POS and slave POS as described above, in which the master POS and slave POS are not tied down at the same time for payment processing. It is about providing.

'41 Structure of the Invention In order to achieve the above object, in the present invention, the slave P
Master PO of own accumulated total information to OS
Providing means for separately storing the collected data in S, and further storing the total information held by the POS in the storage means, regardless of whether there is a data collection request from the master POS when payment processing is started, This device is equipped with a control means for executing payment processing in its own device.

That is, each POS is provided with a function of totaling registered product data (sales data) during normal sales operations.

This aggregated data is held as hard total information. In the present invention, the total information is stored in the payment data storage means (bubble memory in the embodiment) when the payment processing is started, thereby executing the payment processing of the total information.

'5} The present invention will be described in detail below based on examples.

FIG. 2 is a schematic diagram of the POS system according to the embodiment of the present invention.

In the same figure, 6 is a master POS, 7 is a bubble memory for storing collected data provided in the master POS, 8 to 10
11 is a slave POS, 11 to 13 are bubble memories for storing payment data provided in the slave POS, and 14 is a host computer connected to the master POS via a public line. The operation of the improved embodiment system according to the present invention is as follows.

■ When the slave POS (for example, 8) is ready for payment processing, it sends a "payment request" message to the master POS 6, and at the same time sends various total information that has been accumulated up to that point to the payment data storage in the bubble memory 11. Transfer to a.

That is, a process is performed to move the total information, which is cumulatively updated each time a product is registered, to the payment data area of the bubble memory.

When the transfer of ■■ is completed, the slave POS 8 takes out the payment data from the payment data storage area and prints it.

■ During this time, if the master POS is performing normal sales operations, it will continue as is and will not collect data.

Note that the presence or absence of a payment request from the slave POS 8 is notified to the operator of the master POS by, for example, flashing a payment request lamp on the master POS. ■ At any time when the master POS completes its own sales operation,
A “reception OK” message is sent back to the slave POS8.

■ When slave POS 8 receives the "acceptance OK" message, it transfers the payment data in bubble memory 1 to master POS.
Send to.

The mass exchange POS stores the received payment data in the bubble memory 7. As described above, the master POS and slave POS can execute payment processing and data collection processing at arbitrary timings without being distracted by each other's circumstances.

Further, the payment data collected by the master POS is transferred to the host computer 14 and processed as necessary. FIG. 3 is a detailed configuration diagram of the embodiment shown in FIG. 2.

The figure shows the master POS and slave POS for simplicity.
Only one of them is shown. In the figure, 6 is the master POS, 8
is a slave POS. At master POS6, 7
15 is a POS control unit; 16 is a data collection processing unit; 17 is a display; 18 is a bubble memory for storing collected data;
is a keyboard, 18a is an acceptance OK key, 19 is a transaction data memory that stores product prices and other sales conditions, Futagawa printer, 21 is a message analysis unit, and 22 is a processing request POS
23 is a display register, a payment request lamp, and 24 is a message generation unit. In addition, in the slave POS 8, 11 is a bubble memory for storing payment data, 25 is a POS control unit, 2
Reference numeral 6 indicates a payment processing unit, 27 a transaction data memory, 28 a keyboard, 29 a display, and 30 a printer.
To explain the operation, when the sales processing of the slave POS 8 is completed, the settlement processing section 26 in the POS control section is activated from outside the oberley.

The payment processing unit 26 transmits the “payment request” message to the master POS 6.
At the same time, the settlement data of sales up to that point is edited and stored in bubble memory 1. Next, printer 3
From 01, processing to print the payment data is performed. These processes proceed without waiting for reception of the "OK reception" message from the master POS. On the other hand, in the master POS 6, the "accounting request" message from the slave POS 8 is analyzed by the message analysis unit 21, and the processing request PO that sent the message is analyzed.
The S number is identified and the contents of the message are decoded.

Based on the identification result of the processing request POS number, the processing request POS
A predetermined bit position of the display register 22 corresponding to the POS is set to "1". As a result, the payment request lamp 23 blinks to notify the operator that there has been a payment request from the slave POS. While the master POS is performing normal sales operations, the master POS operator does not need to immediately respond to payment requests and perform data collection operations, and the master POS can suspend sales operations or terminate operations. The payment request can be placed on hold until such time as the payment request is made. Master POS
The other slave POS processes the first checkout request.
In some cases, further payment requests may be sent.

At this time, similarly to the first payment request, the POS location is stored in the processing request POS display register. When the master POS operator becomes able to perform a data collection operation, he presses the reception OK key on the keyboard 18 to start the data collection processing section 16.

The data collection processing unit 16 provides a processing request POS display register 22 and displays one slave PO that has issued a processing request.
S number is identified, and control to collect payment data from the slave POS is started. The data collection processing unit completes a communication connection with the processing request slave POS,
The message generation unit 24 specifies the slave POS and transmits an "acceptance OK" message.

The integration processing unit 26 of the slave POS
When receiving the message, it confirms that it is in a state where it can transfer its own data, sends the payment data from the bubble memory 1, and transmits it to the master POS 6 as a message. The master POS 6 decodes the received "accounting data" telegram using the telegram analysis section 21, identifies the POS number, sends it to the data collection processing section 16, and stores it in a predetermined file area of the bubble memory 7. .

When the settlement data collection process for one slave PS is completed, the bit “1” of the process request POS display register 22 is reset.

Furthermore, if the slave POS performs a sales operation after making a payment request and receives a "reception OK" message from the master POS during the sales operation, the payment data is transferred after the sales operation is completed by interrupt processing. It can be configured as follows. When processing requests from multiple slave POSs overlap, they are processed in the order of reception or in a predetermined order (for example, in order of POS number).
Many other known queue management or priority control techniques may be used. Also, if the master POS has multiple slave P
Many conventional techniques can also be used for a method of selectively establishing a communication connection with any one of the OSs. ■ Effects of the Invention According to the present invention, the master POS and slave POS can execute the payment processing and data collection processing at timings that are independent of each other, and the two POSs can be tied up for these processing at the same time. It never becomes a state.

In addition, each slave POS temporarily stores the payment data or cumulative data in a file memo such as a bubble memory, so if an error occurs in data collection, it is possible to collect data again, increasing reliability. It helps to improve.
