Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data transmission method used in a POS system.

[Summary of the Invention 1 This invention provides a data transmission system that queries classification setting data stored in classification files in a master side type r-device in accordance with classification registration in a slave antistatic r-device. On the slave side, a registration memory is used to sequentially store the classification data that is inputted to the IFF when registering one classification, together with the classification setting data transmitted from the master electronic device in response to an inquiry from the slave side type r-function. 'tun/
' - By providing the device in the device, if the classification setting data corresponding to the input classification data is already stored in the registration memory, the inquiry for the classification setting data is not made.

[Conventional technique vM] Conventionally, in ECR (electronic cash register) and POS systems, multiple slave ECRs are connected to the master full EcR, and sales data for each product is stored in the master ECH. A centralized data transmission system is known in which a FLU file is created for each slave @ECR, and the PLU 'yj'l sell I- data sold at each slave @ECR is transmitted to the master side ECR and collected in the FLU file. It is being

In such a centralized data transmission system, each time FLU registration is performed on the slave side, the product code (FLU code) input from the barcode reader is transmitted to the master side.
Query the rIi value stored in the file,
Then, in response to this inquiry, the unit price and other data transmitted from the master side are used to calculate the selling price and the like.

[Problems to be solved by 151] However, as mentioned above, since there is a 111-value inquiry in iIj where PLU-specific registration is performed on each slave side, the problem is that the burden on the slave side increases significantly. was there. Furthermore, if the condolence price is changed during registration for the same customer, there is a problem in that even products are registered at different unit prices.

This invention has been made in view of the above-mentioned circumstances, and its purpose is to reduce the burden on the master side and, for example, to enable the master side to set data by classification such as I'n value. Even if a change is made, on the slave side, if the same customer is registered, is it the same product? An object of the present invention is to provide a data transmission method that allows registration without changing the n value.

[One step to solve the problem] FIG. 1 is a functional block diagram showing the configuration of this 511JI. In the figure, 1 is a master electronic device, 1a is a classification file that is provided in the master electronic device and stores classification setting data, 2 is a slave electronic device, and 2a is a file that is stored in the slave electronic device. , is a registration memory that sequentially stores a plurality of classification data sequentially inputted in accordance with classification registration into classification setting data transmitted from the master side electronic device.

[Sakukawa] The master side ``Ichiko device 1'' responds to the inquiry for the classification setting data from the slave side electronic device 2 by sending the classification file 1.
a is searched and the classification setting data obtained thereby is transmitted to the slave anti-static r-aX2 that made the inquiry. In addition, the slave side device 2 detects whether or not classification setting data corresponding to the classification data inputted with classification registration is stored in the registration memory 2a,
As a result, if it is detected that the data is stored, no inquiry is made for the setting data by category, and if it is detected that the data is not stored, the inquiry is made for the setting data by category.

[Embodiment] Hereinafter, an embodiment of the present invention will be explained in detail with reference to FIGS. 2 to 6. FIG. 2 is a basic block circuit diagram showing an ECR data transmission system. Master [

The counter C1 has a configuration including a one-transaction registration memory D that sequentially stores registration data for transactions. Here, - transaction registration memory D has FLU numbers,
It stores the trade price and the number of items sold and sold, and the contents are cleared when the closing key to end the transaction is operated.

Note that the other slave side ECR13 is also shown with a number because it has the same configuration as described above, and its explanation will be explained below.
Omit I.

肱-1 Figure 3 is on the master side ECRII・Every fixed time; 1.1
FIG. 4 is a flowchart showing the registration operation executed in each slave ECR 13. First, when performing PLU-specific registration in the slave ECR 13, a registration mode is selected using the mode changeover switch MS, and then a bar code (FLU number) recorded on a product label or the like is read using the fixed scanner 13C. As a result, the flow shown in FIG. 4 is started, and first, it is determined whether this is the first registration in a - transaction based on the contents of the registration counter B (Stella 7'
Sl), if the value of the registration counter B is rQJ, it is determined that this is the first registration, so step S
Proceed to step 6 and transmit the FLU number input this time, which has been transferred to PLU number memory A, to the master side ECRII and inquire about the unit price for that PLU number.
Then, in response to this inquiry, the master side ECR 11
The received code of the trL value transmitted from - becomes the received code (step S7).

Here, in the master side ECRII, the flow shown in FIG. 3 is executed at fixed intervals. First, in step S21, the master 1 is executed. FLU
It can be checked whether there was any data input associated with separate registration, etc. If there is no data input on the master side, step S
23, it is checked whether data transmitted from the slave side ECR 13 has been received, and if there is no received data, exits from this flow. Therefore, the master side ECR1
1, data input on the master side or data reception from the slave side is detected at regular intervals. Assuming that there is now an inquiry about the rIt price from the second slave side ECtt13, this is detected in step S23 and the process proceeds to step S24, where the one transaction registration memory D of the slave side ECR13 that received the unit price inquiry is in a full state. (overflow condition 4') or - tllfi is executed to determine whether the registration of the transaction has been completed and the resignation key has been operated. Now, since this is the first registration of a transaction, it is neither the full state 55 of the single transaction registration memory D nor the close key operation, so proceed to step S3O, respond to the inquiry about the unit price, and send the PLU From the file to the corresponding FLU number? The i-value data is read and transmitted. In this case, +k 'i in the PLU file
When the second middle price selection flag corresponding to the PLU number is turned on, the second condolence price is transmitted, and when it is turned off, the first condolence price is transmitted to the slave ECR 13 that made the inquiry.

In this way, the master IIE responds to unit price inquiries.
When the unit price data is transmitted from the cRII, the slave side ECR 13 detects this in step S7 in FIG. Increment processing of +1 is executed. and register the number of registrations counter B.
In step 1, the σ record memory D for one transaction is addressed, and the addition process (step S9) of adding 1 to the number data in the specified address area D (B) is executed. Then, the registration process (step 5lO) is executed. In this case, the FLU number is stored in the address area D(B) of the transaction registration memory D.

The received rIt value data is stored, and the input data is displayed, printed, and subtotal addition processing is executed. By this, for example, - on the first registration of Torikyu 1.

As shown in FIG. 2, the FLU number "2", the unit price rlO yen, and the number rl of 1 piece are stored at address 1 of the one-transaction registration memory D. After that, it is determined whether the transaction registration memory D is full or not when the value of the registration number counter B is its final address rn.
You can check depending on whether it has become J or not. At this point, the first registration of the transaction is Al', so the transaction registration memory D has not yet reached its full state, and the process exits from this flow.

When the next registration is performed on the slave side ECRl 3, the process proceeds from step 31 to step S2.
A4 of the registration number counter B is transferred to the subtraction counter C. Then, one transaction registration memory D is addressed by &j of this subtraction counter C, and the FLU number in that designated address area and the FLU number memory A input this time are
A determination is made whether the FLU nanopars within are equal. here.

If the FLU number registered for the number of songs and the PLU number input this time are not equal, the process (step 34) of decrementing the value of the subtraction counter C by l is executed, and in the first step, 4fi of the subtraction counter C becomes "0". Here, if the value of the subtraction counter C is not "0", the process returns to step S3 and it is determined that the PLU number registered once and the PLU number input this time are the same. You can check what happened. In this way, the contents of the transaction registration memory D are accessed in the reverse direction, and a search is made to see if the same FLU number as the currently input PLU number is stored in the one transaction registration memory D. In this case, - As a result of searching all the FLU numbers in the transaction registration memory D, if the same - PL[J number is not stored, proceed to step S6 and make an inquiry of the 11-valent value to the master side ECRII. .

As a result, when the ri value data is sent from the master ECRII, the steps S7 to SIO
Move on to execution. This allows, for example, - trading 2nd 1st
1 has been registered, the FLU number r3J,
? i price r20 yen'' 1 quantity rlJ is stored. As a result of this operation being executed every time a registration is performed, if the FLU number input this time is not stored in the registration memory D for one taker, the unit price is queried and transmitted from the master side ECRII. When the received rB price data is sequentially stored in the registration memory D for one transaction, the registration is performed based on the received unit price data.On the other hand, the registration memory for one transaction is stored in accordance with the FLU number input this time. D
As a result of the search, the same F is found in the transaction registration memory D.
Step S'''・3 indicates that the LU number is stored.
If it is searched for, step S3 to step St
Proceeding to t, an addition process is performed in which the number of items sold corresponding to the FLU number stored in the -transaction registration memory D is incremented by 1. Then, the unit price data corresponding to this FLU number is read from the one transaction registration memory D, and registration processing (display, printing, subtotal addition 'Q) is performed based on this (step 512). Therefore, - In the transaction, If the FLU number of a product that is the same as an already registered product is entered, the RP price is not queried to the master side ECRII, but is stored in the 1's own 1 transaction registration memory D. Registration is done based on the unit price.

However, if it is detected in step 313 that the registration memory D for one transaction becomes full during the registration of a large number of transactions.

Proceeding to the next step 314, all data in the transaction registration memory D except for the data in the final address area are sequentially transmitted to the master side ECRI I. Then, after clearing (/i) of the registration number counter B, its value is +l and initiality "1" is added to the 0 recording number counter B (step S15, 916). Next,
- A data editing process (step 317) is performed to transfer the data in the final address area of the transaction registration memory D to its first address area. Such editing processing is performed in preparation for last-minute revision +E, and - transaction registration memory D
Even if the data is full, the data registered in the direct curve is retained in its first address area, so it can be corrected. It is checked whether predetermined data, which will be described later, has been transmitted from the ECRII (steps 31B and 5).
19), even after a certain period of time, the master side ECR1
If the predetermined data is not transmitted from 1, the process exits from this flow, but if the data is transmitted, the received data is sequentially stored in the registration memory D. An import process is performed (step 520).

Here, the master [in ECR11, the slave side E
When data is transmitted from the CR 13 according to the full state of the registering memory D, step S2 in FIG.
3. This is detected in S24, and the process proceeds to step S5, where it is checked whether the data transmission is in response to the closing key operation. Now, since the data transmission is in accordance with the full state of the transaction registration memory D, the process proceeds to step 326, and the second width selection flag in the FLU file is set in accordance with each FLU number transmitted from the slave side ECR 13. The search is performed sequentially, and as a result, it is determined whether the second condolence value selection flag is turned on. Now, assuming that the second width price selection flag is on, the unit price corresponding to the FLU number transmitted from the slave (llEcR13) is the first width price selection flag.
It is possible to check whether the tit value is high. Here, if the second unit price selection flag corresponding to the searched PL [J number is turned on and the unit price of the transmitted FLU number is the first school price, then the This is a case where there is a change from the first width price to the second unit price in 2. In this case, proceed to step 32g and change that FL.
The U number 8 and 1 width value are transmitted to the slave side ECR 13. Therefore, - Even if the unit price is changed on the master side ECRII during registration of a transaction, the original first width price will be applied instead of the changed second tonne price for those already registered at the first middle price. The value is sent back to the slave side ECR 13. Then, in the first step S29, the data transmitted from the slave side ECR 13 is sent to the PLU.
A data collection process is performed to add to the file.

In this way, when the first RI value data etc. are sent back to the slave ECR 13 in step 528, the received data is sequentially stored in the transaction registration memory D in the slave ECR 13 in step S20 described above. As a result, the transaction registration memory D stores the PLU number whose middle price was changed during registration of the transaction and its first m-price. As a result, even if the same product is registered in subsequent registrations for that customer, it will be registered at the same unit price.

FIG. 5 shows the correction process executed in the slave side ECR 13. When correcting selling data, after operating the correction key, the PLU number to be corrected is read by the 1/4 constant scanner 13C.

As a result, the flow shown in FIG. 5 is executed. First, the value of the registration number counter B is transferred to the subtraction counter C (step 531), and
414 memories D for one transaction are addressed, and the FLU number and FLU stored in that designated address area are
A match with the revised IEP LU number read into the number memory A is detected (Step 532). If the sell 1-data registered immediately before is to be corrected, a match is detected in Step S32. However, if it is not a face correction, a mismatch is detected and the process proceeds to step 333, where 4Ij of the subtraction counter C is incremented by -l. As a result, the next step S
34, it is checked whether the value of the subtraction counter C is "0", and r
If it is not OJ, the process returns to step S32, and steps 332 to S34 are repeated until the corrected FLU number is retrieved. Now, when the corrected PLU number is retrieved, the process proceeds to step 336, where the correction II' process is performed and the transaction registration memory D is addressed by the value of the subtraction counter C.
The number of sold items within is decreased by 1. Then, the corrected +E data is printed and displayed (step 537), while - as a result of searching the transaction registration memory D, the corrected PLU number is
If it is not stored in the transaction registration memory D, -・
Since the transaction registration memory D has become full and all its contents have been transmitted to the master side ECRII, in this case, the process advances to step S35, where a correction lamp (not shown) is lit for a certain period of time. Knowledge is done. In this case, corrections are made by checking the receipt printout and inputting keys.

FIG. 6 is a flowchart when a closing key such as a cash/deposit key is operated on the slave side ECR 13.

First, when the close key is operated.

Normal closing processing (step 541) is executed. Then, all the data in the transaction registration memory D is transmitted to the master side ECRII (step 542). Thereafter, the contents of the -taken registration memory D are all cleared, and the contents of the PLU number memory A, the number of registrations counter B, and the subtraction counter C are cleared, respectively (step 343).
．． 544).

In this way, when the transaction registration is completed and the close key is operated, all the data in the transaction registration memory D is transmitted to the master side ECR1t.
In CRII, this is detected in steps 523 to 325, and the process proceeds to step 329, where the received data is sent to FL.
Processing to add to the U file is performed.

In the first embodiment, data by FLU was explained, but the same function can be applied to data by department.

"Effects of the Invention" This invention is based on the following: As explained in detail, the classification settings stored in the classification file in the master side type r device along with the classification registration in the slave device In a data transmission system that queries data, data by category that is input sequentially during registration by category is sent to the slave side type r-
By transferring the registration memory that stores the 111th level along with the classification setting data transmitted from the master antistatic device in response to an inquiry from the device to the slave F/A device, the input classification data can be stored. If the corresponding classification setting data is already stored in the registration memory, the inquiry for the classification setting data is not made, which reduces the burden on the master side and also allows the master side to easily divide inner pages, etc. Even if the classification setting data is changed, the slave side can register the same product without changing its Φ value as long as the same customer is being registered.
