Abstract

PURPOSE:To store many account settling data in a small buffer area by discriminating an account settling data from plural counting-up devices by a sequence number of the time when transferring the data, and preventing a double addition, too. CONSTITUTION:When adding one account settling data to a counting-up buffer B, a check of the following items is executed in a check processing part 17. (1) Only the case when a date contained in a telegraphic message is the same as a date in a master POS is made an object of addition. (2) Only the case when a sequence number contained in the telegraphic message is larger than a sequence number stored in a continuous number shunting area 19 corresponding to a POS number is made an object of addition. Only the account settling data for satisfying simultaneously said two items is added, and when the addition processing has been ended, the sequence number of its telegraphic message is shunted to the continuous number shunting area 19 corresponding to its POS number.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention uses a precision data collection method, in particular, it is possible to correctly add and process multiple settlement data transferred from the same terminal aggregation device to a mask aggregation device. This relates to the settlement data aggregation method.

(2) Background of the technology When setting up an automatic data collection system using a computer, a master data collection device, ie, a master PO8 (POS: Po1nt or 5al
e; a totaling device that can create data at the time of product sales) is installed, and terminal milk collection device 1, that is, terminal PO8, is connected to this master PO8, and each terminal PO8 is connected via the master PO8, and furthermore, a telephone Ri data collected to the host computer via line etc. (hereinafter referred to as sales data)
There is a data collection nI method that allows the transfer of data. In such a data aggregation method, in general, among the above sales data, the sales amount 1'111i is stored in the master 1-111i.
) It is stored as settlement data in the memory of O8, so that the sales amount of each terminal PO8 or the entire business entity can be grasped at once. Such data collection Jl
In this method, it is necessary that the fil data transferred from each terminal PO8 to the master PO8 is always correct, but there are some concerns about the occurrence of an abnormality such as a line failure.

(3) Prior Art and Problems Conventional data collection nI methods of this type include those shown in FIGS. 1 to 3, for example.

Of these, Fig. 1 is a diagram of the 1=th system that executes the j゛-event aggregation formula, and Fig. 2 is a schematic diagram of the internal 4f5''#i of terminal 1] O8 used in the system of Fig. 1. Figure 3 is the first
It is a schematic block diagram of master PO8 in the system of a figure. In the figure, PO31 indicates master ]) O8, P OS 2,
PO33 and PO34 indicate terminal PO8 connected to master PO81. Each terminal PO 32, 3, 4 transfers sales data through each line 2.3.4 and line 1 to the master l) OS 1 and further to the boss it lml-1. The master PO31 includes all pos i including the master PO31.

Regarding 2.3.4, memory for storing settlement data among sales data, that is, buffer B for storing settlement data.
1. B2. +3 3,134. is the number of PO8 (prepared correspondingly).The terminals PO32, 3゜4 are connected to the hardware 1-1 connected to the data power line 7, as shown in FIG. The hardware section 5 has a logging section 5 and a logging file section 6.The hardware 1-1 logging section 5 receives sales data (item, amount, quantity, time, etc.) related to individual sales from a data input line 7. When the data is logged, data mainly related to the sales amount is stored in stacks each time it is input.In the logging file section 6, the sales data of the above-mentioned sides are stored with serial numbers added each time they are input. Then, at the end of the day's work, the hardware total section 5 performs the settlement for that day, and the essential data is stored in the logging file section 6. On the other hand, the master P
O31 is created based on instructions from the CPU (central processing unit) 9.
11, the public line control unit 10 that connects the line to the host Sl computer H, the transmission buffer 11, and each terminal PO32 (hereinafter, only PO32 will be represented). The internal line charge i11 section 12, the reception buffer 13, the line control section 14 that determines whether or not the data transferred from the terminal PO32 should be transferred as is to the host total 111111-1, and the same system that goes to the terminal PO32. Hard total unit 15, logging fill unit 16, and a number ff corresponding to the number of PO8s! (7)/<7
It consists of AB1 and B2.83.84. Then, when the work on -day ends, all sales data including settlement data is transferred from the logging file section 6 of the terminal PO32 to the line 2.
The data is sequentially transferred to the master PO 31 through the . Master P
The sales data transferred to O31 is sent once to the mυ control unit 14 via the local line control unit 12 and the reception buffer 13, where it is checked whether or not it is settlement data. When the sales data is settlement data, the data is stored in the buffer B2, and is sent to the host Kln IN +- through the transmission buffer 11 and the public line control unit 10.
Transferred to 1. However, if the above sales data is data other than settlement data, the transmission buffer 1 is immediately
1 and the host Sl computer 1- through the public line control unit 10.
Transferred to 1. Similar data transfer operations can be performed on other terminals PO.
C is done in exactly the same way for 33,4, and all P
The data transfer for O31,2°3.4 completes the sales aggregation process for that day. Since the storage of the essential data in the buffer B2 is normally performed once a day, every time new settlement data is stored in the buffer B2, the old essential data stored before that time is cleared. Ru.

However, in such a conventional detailed data aggregation method, the mass IP POS 1 requires several buffers corresponding to all the PO8s, so the terminals PO32, 3
, 4 is uneconomical if the number of connected devices increases, and even though buffers were prepared in anticipation of the maximum number of connected devices when creating the system, when the number of connected devices is small, the master PO31
There was a problem that a wasted area was created. In addition, since the buffer structure is such that old payment data is cleared when storing new payment data, the last transferred data remains in the buffer, so if there is an empty payment etc. There is a problem in that if invalid data is transferred, valid data will be lost. Furthermore, terminal PO32 during work
Due to some reason such as trouble, the same terminal PO32
In the case where settlement is performed twice, the first settlement data is stored first, and then the second settlement data is stored, even though the two settlement data should be added and stored in buffer 2. Since the first data is cleared when the data is transferred, there is also the problem that the correct data is not stored in the buffer 2.

(4) Purpose of the Invention The present invention has been made in view of the above-mentioned problems, and its purpose is to provide the master PO8 with an addition function when aggregating payment data, and also to prevent double addition.
The purpose is to be able to store Kamaishi's essential data in a small buffer area.

(5) Structure of the Invention The gist of the present invention is that, in order to achieve the above object, each terminal is aggregated by a master aggregation device having a buffer for storing payment data, and a terminal aggregation device connected to the master aggregation device through a line. In a data aggregation method in which the settlement data collected by the device is stored in the buffer door of the mask aggregation device, the settlement data from multiple aggregation devices is stored in a single buffer while being differentiated by the sequence number at the time of data transfer. On the other hand, if the mask aggregation device is equipped with a function to add multiple pieces of settlement data when stored in a buffer, and multiple pieces of fine data are sent from one aggregation device to the mask aggregation device, it is possible to add the multiple pieces of settlement data. The settlement data collection 81 method is characterized by being able to determine whether or not the transaction is possible.

(6) Description of Embodiment Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Figure 4 is a system diagram for executing the data aggregation method of the present invention, and Figure 5 is a master P used in this system.
It is a schematic block diagram of O8. In Figure 4, the master PO
320 includes all PO3s including the mask PO320.
A single memory for storing settlement data behind sales data for POs 2, 3, 4, and 20, that is, a buffer B for storing In data, is provided for each PO32, 3, and 4゜2.
A region 1fi19 for saving a sequence number (sequential number) corresponding to 0 is provided. Also master 1) OS
20 sends the sales data transferred from the terminals PO32, 3, and 4 to the line control unit 14 through the horizontal line control unit 12 and the reception buffer 113, and then sends the sales data to the host via the transmission buffer 111 and the public line control unit 10. At the point of transfer to the group n machine 1-1 - [the conventional master P
The configuration is similar to that of OS 1, but unlike this conventional example, the line control unit 14 contains information on whether the Panoko data transferred from the logging file unit 16 of the terminals PO32, 3, 4 and the master PO320 is payment data. A check processing unit 17 that determines whether or not the result is true, and a calculation processing unit 18 are incorporated. The check processing unit 17 is a terminal and a master PO 32,
When the sales data from 3, 4, and 20 is settlement data, the sequence number assigned to the data is stored in the serial number save area 19.

This allows us to know from what PO8 and what number [I's O-ging area the above-mentioned refined data has come out. If the check data checked in the check processing unit 17 is to be added to the previous calculation data, the old calculation data and the new data are added in the calculation processing unit 18. The serial number save area 19 consists of a type of register that covers a predetermined number of digits n, and the number of consecutive number save areas 19 is equivalent to the number of PO8s ()
(Four units in this embodiment) are provided.

An example of processing operations in a data transfer system having such a configuration will be explained.

First, when creating a message for data transfer in the logging file section 6.16 of each PO 8, a sequence number starting from 0001 is attached to each message, facing each other, from the time the station is opened. Furthermore, data such as PO8 number and [1 attached] are also included in the message.

Next, when adding one fine n data to the buffer B for the collection 81, the check processing section 17 checks the following items.

■ Day included in the message (=E when j is in master PO8)
Is it the same as "I"?

→ Only the same cases are subject to addition.

(2) Whether or not the sequence number included in the message is larger than the sequence number stored in the sequential number save area 19 corresponding to the PO8 number.

→Only cases where the value is large are subject to addition.

Only the payment data that satisfies the above two items at the same time are added, and after the addition process is completed, the sequence number of the message is saved in the serial number save area 19 corresponding to the P2S5 number.

As a result, even if the 1C settlement data that has already been stored in the buffer B is transferred to the master PO 320 again at 3 o'clock, it will not be subject to addition due to the sequence number check by the check processing unit 17. Aggregation errors can be prevented. Also, sky vi
Businesses such as calculations are often performed immediately after the line is opened, and the sequence number attached to the message is small.However, since the actual transaction settlement is often done at the end of the transaction, it is given to the message of settlement data. The sequence number will be a relatively large value. Therefore, even if invalid payment data such as an empty payment is sent after the totalization, it will not be added to the data due to the jitance number check.

(7) As described in detail, according to the present invention, when aggregating In data, the settlement data from a plurality of aggregation devices are stored in a single buffer while being distinguished by sequence numbers at the time of data transfer. At the same time, since multiple settlement data from one aggregation device are added while preventing double addition, the buffer area for aggregation of settlement data can be reduced.
Furthermore, various effects can be obtained, such as being able to correctly tally payment data even if there is a problem with the POS.
