Description

TECHNICAL FIELD The present invention relates to a sales data processing device such as an electronic register.

[Prior Art] In general, as a device for transmitting data from an electronic register to a data collecting device, there is, for example, one disclosed in Japanese Patent Laid-Open No. 59-79573, and in such a device, normal data is transmitted. Transmission is performed using a telephone line, but for example, by department, product category, time zone, transaction,
By selecting and transmitting only the items required by the user from the sales data for each person in charge,
We are trying to save money by shortening online time and running costs such as telephone charges. Thus, when transmitting sales data, unnecessary data is omitted as much as possible.

By the way, when transmitting the details of sales data by product category,
If the number of product items is extremely large, the data transmission time will increase in proportion to this and the telephone charge will also increase. Therefore,
For electronic registers and data collection devices that have the same unit price set in advance for each product category (PLU) number, do not transmit the total sales amount when transmitting data, but only the PLU number and the number of units sold. It is conceivable that the data is transmitted.

[Problems to be Solved by the Invention] However, in this type, on the data collection device side, the corresponding unit price is read from the transmitted PLU number, and the total sales amount is calculated based on this unit price and the number of sales sold. However, if the unit price differs between the electronic cash register and the data collection device, or if the unit price is changed in the electronic cash register, it is not possible to calculate the accurate total sales amount, and the accurate data totalization cannot be performed. Could not be performed.

Therefore, it has been considered that when the unit price is changed in the electronic register, the sales data input at the time of registration is transmitted to the data collection device so that the total sales amount can be accurately calculated.

However, even if the unit price is continuously changed from a certain transaction, in the above-mentioned case, the sales data must be transmitted to the data collection device each time the sales data is registered, The transmission process becomes very troublesome.

An object of the present invention is to make it possible to shorten the transmission time when transmitting sales data to a data collection device.

[Means for Solving the Problems] Means of the present invention are as follows.

In a sales data processing device that is connected to a data collection device and sends sales data to the data collection device, a sales total memory that stores the unit price and the total number of units sold corresponding to the product classification code, and a product classification that changes the unit price A change unit price input means for inputting a code and a change unit price, and an evacuation means for reading out the unit price and the total sales quantity corresponding to the product classification code input by the change unit price input means from the sales total memory and storing them together with the product classification code. , Unit price changing means for changing the unit price of the total sales memory corresponding to the product classification code input by the changed unit price input means to the changed unit price, and a unit price for storing data indicating the unit price change corresponding to the product classification code The change storage means and the total sales quantity corresponding to the product classification code stored in the total sales memory are displayed in the above-mentioned data. When the unit price is changed, the contents of the unit price change storage means are referred to, and when there is no unit price change, the product classification code and the total number of sales are transmitted. Based on the unit price before the change, the total number of sales and the changed unit price, and the total number of sales stored in the saving means respectively, the total number of sales and the total amount of sales are calculated, and the product classification code,
And a transmission means for transmitting the total sales quantity and the total sales amount.

[Operation] The unit price and total sales quantity are stored in the total sales memory corresponding to the product classification code. When changing the unit price, if you input the product classification code and the changed unit price by the changed unit price input means, the evacuation means reads the unit price and total sales quantity corresponding to the product classification code input by the changed unit price input means from the total sales memory. The unit price change means changes the unit price of the total sales memory corresponding to the product category code input by the changed unit price input means to the changed unit price, and the unit price change storage means corresponds to the product category code. The data indicating the unit price change is stored.

Then, the transmitting means refers to the contents of the unit price change storage means when transmitting the total number of sales corresponding to the product classification code stored in the total sales memory to the data collection device, and if there is no unit price change, the product classification code If the unit price is changed, the total unit sales and the unit sales are stored based on the unit price before the change, unit total unit sales and unit unit price and unit unit price stored in the total sales memory and saving means. Calculate the total amount of money and send the product classification code, the total number of units sold, and the total amount of sales.

Therefore, when sending sales data to the data collection device,
The transmission time can be shortened.

Further, a transmission control unit 6 connected to an electronic register on the central side of the headquarters via a telephone line is connected to the CPU 2 in the phase direction. The transmission control unit 6 has a transmission buffer,
Data is transmitted and received via this transmission buffer.

Other electronic registers on the POS terminal side Tb …… T
Since k has the same configuration as the electronic register Ta described above, its configuration is omitted in the drawing.

Next, the circuit configuration of the electronic register C on the center side of the headquarters will be described. Since the main part of the electronic register C has the same structure as that of the POS terminal side, the parts having substantially the same structure are indicated by the same reference numerals with "'" (dash) and the detailed description thereof is omitted. In addition to various keys, the key input unit 1'is provided with a transmission key 1'f that requests data to be transmitted to an electronic register on the POS terminal side. In addition, the RAM2'd of the CPU2 ', in the row direction,
The configuration has t ₁ , t ₂ , a, b, and f registers. Here, the t ₁ , t ₂ , a, and f registers are registers for storing data transmitted from the POS terminal side, that is, corresponding sales quantity data, sales amount data, PLU number, and flag data. The b register stores predetermined address data. Further, the sales totalizer 3'is configured to have a total memory M'by product category and another total memory CM ', and the total memory M'by product category is different from the memory M on the POS terminal side.
Instead of storing the flag data corresponding to the LU number, the total sales amount is stored. CPU2 ′
Outputs a data transmission request signal, an ACK signal (acknowledgement signal) for data transmission, a NACK (negative acknowledgment signal), etc. to the transmission control unit 6 '.

Next, the operation of the above embodiment will be described. First, the electronic register C on the head office center side presets the product name and unit price corresponding to the PLU number, and the preset data is transmitted to each electronic register Ta to Tk on the POS terminal side, and the PLU number is stored in the main total memory M thereof. It is assumed that it is set according to.

In this state, when changing the set unit price on the POS terminal side before or after registration is started, the procedure is performed according to the following key operation procedure. First, the mode selector switch 1e is switched to the "PR" position to set the setting mode. In this setting mode, the unit price key 1d is operated by inputting the changed unit price. Then PL
Enter the U number and enter the PLU key 1c. When the PLU key 1c is operated according to such a key operation procedure, the operation according to the flow of FIG. 3 is executed. First, in step S ₁ , the auxiliary total memory m of the sales totalizer 3
Increment processing for incrementing the content of the area PT provided in +1 is executed, and the stored maximum address data in the auxiliary total memory m is updated. When changing the unit price,
The input PLU number is written in the address area n (PT) of the auxiliary total memory m which is addressed by the contents of the area PT by the execution of the next step S ₂ . In the next, in step S _3, sequentially reads the PLU number of the primary total memory M searching for PLU number equal to the PLU number entered, this process of transferring the A register corresponding address data obtained by the execution To be done. In this way A
The main total memory M is addressed based on the address data set in the register, and the designated address area M
From (A), the unit price data (step S ₄ ) is read first, and then the piece number data (step S ₅ ) is read out, and the auxiliary total memory m
Are sequentially written in the designated address area m (PT). That is, in steps S ₄ and S ₅ , the contents of the main total memory M (unit price and number data before the change) are changed as the unit price is changed.
Is transferred to the auxiliary total memory m and saved. When such transfer processing is completed, in step S _6, the inputted modified bid data is written to the specified address area M (A) of the primary total memory, followed by step
In S _7, the number data of the address area M (A) is erased, and Thus, in the last step S _8, the address area M
"1" is written in (A) as flag data. This makes it possible to specify that the unit price of the corresponding PLU number has been changed.

Then, at the headquarters center side, a data transmission request signal is output from the headquarters center side in response to the operation of the transmission key 1'f, and when the data transmission request signal is input to the CPU2 at the POS terminal side, the POS terminal CPU2 on the side is the fourth
The operation according to the flow in the figure is executed. First, in step S _11, initialization processing for setting "1" as the initial address data in the B register is executed. Next, a process of reading flag data from the address area M (B) of the main total memory M addressed by the contents of the B register and transferring it to the F register (step S ₁₂ ).
After executing, whether the content of this F register is "1",
In other words, the unit price change presence / absence determination process (step S ₁₃ ).
Is executed. Since the flag data corresponding to the PLU number for which the unit price has not been changed is “0”, in this case,
It is determined that determination in Step S _13, the process proceeds to step S _14. Here, the flag data “0” and the PLU number and number data read from the designated address area M (B) of the main total memory are transmitted to the head office center side. Therefore,
In the next step S _15, whether or not the contents of the B register has reached the final address "l" of the major total memory M or not.
If the answer is NO, an increment process (step S ₁₆ ) is performed to set the contents of the B register to +1 and then the process proceeds to step S ₁₇ to check the presence / absence of an ACK signal from the head office center side. As a result, when the headquarters center side reliably receives the transmission data, an ACK signal is output from the headquarters center side.
While returning to S _12, when it is determined that "no", the flow proceeds to the next step S _18, this time is checked whether NACK signal. Here, the case where it is judged that there is a NACK signal is a case where an error occurs in the data transmitted to the headquarters center side.In such a case, in order to retransmit the same data, After executing the process of subtracting "1" (step S ₁₉₎ from the contents of the B register updated in S _16, it returns to step S _12, when it is determined that "None", the step S ₁₇ Return, ACK signal or NACK
It stands by until either one of the signals arrives.

On the other hand, in step S _13, the flag data in the F register is "1", in other words, if there bid change is detected, the address region M corresponding to the PLU number
The quantity data of (B) is written in the T ₁ register (step S ₂₀ ), and then the unit price of the address area M (B) is multiplied by the quantity data to calculate the total sales amount by product category, The total sales amount obtained by this is written in the T ₂ register (step S ₂₁ ). Then, step S ₂₂ ,
In S ₂₃ , S ₂₄ , and S ₂₅ , the corresponding PLU from the auxiliary total memory m
The process of searching for the number is executed. That is, first,
Sets "1" as the initial address data in the C register (step S _22), PL from the address area of the auxiliary total memory m (C) addressed by the contents of the C register
The U number is read and the PLU of the PLU number area M (B) is read.
It is determined whether or not it is equal to the number (step S ₂₃ ), and if it is determined as negative as a result, the process proceeds to step S ₂₅ via step S ₂₄ , and the process of setting the content of the C register to +1 is executed. after being to return to step S _23. Thus if it is determined "YES" in a search operation in accordance with the step S _23, the number data of the address area m (C) corresponding to the PLU number is accumulated in the T ₁ register (step S
₂₆ ) and then the total sales amount obtained by multiplying the unit price of the address area m (C) by the number data is accumulated in the T ₂ register (step S ₂₇ ). This gives T ₁ , T
The contents of the ₂ register are the cumulative value of the number of units sold or the total amount of sales before and after the unit price change, that is, the number of units actually sold or the total amount of sales.

Then, in the next step S ₂₈ , the stored maximum address data of the auxiliary total memory m stored in the area PT and C
It is determined whether the address data of the register is the same. When it is determined not Here, C in step S ₂₅
To return to the step S ₂₃ after updating the contents of the register. That is, when the unit price of the same PLU number is changed by two or more, the same PLU number is stored in the auxiliary total memory m over two or more address areas. It is for searching. Therefore, when the unit price of the same PLU number is changed more than once, as a result of performing steps S ₂₆ and S ₂₇ sequentially,
The contents of the T ₁ and T ₂ registers are cumulative data for the number of changes.

And Thus, if it is determined "YES" in the step S ₂₄ or step S _28, the process proceeds to step S _29, PLU number of the flag data "1" and the address area M (B), T ₁ and T ₂ After the process of transmitting the contents of the registers is executed, the process returns to step S ₁₅ . As a result, if “YES” is determined in step S ₁₅ , the process proceeds to step S ₃₀ and a transmission end signal is transmitted to the headquarters center side.

In this way, when transmitting sales data from the POS terminal side to the headquarters center side, the PLU number that matches the preset unit price on the POS terminal side and the headquarters center side,
That is, the PLU whose unit price was not changed on the POS terminal side
The number, as shown in step S _14, only the transmission number data as sales data, also do not match PL
U number, i.e., for the PLU number for which the unit price changes, as shown in step S _27, in addition to the number data as sales data, to calculate the actual total amount data revenue obtained (total amount of about bid change) To transmit.

Next, the operation of the headquarters center side will be described. "pay off"
When the transmission key 1'f is operated in the mode, the fifth key
The operation according to the flow in the figure is executed. First, in step _S51 , a data transmission request signal is transmitted to the POS terminal side. In the following, the process proceeds to step S _52, a check data transmission whether from the POS terminal side. As a result, "Yes"
If it is determined, the process proceeds to the next step S ₅₃ , a check calculation (for example, parity check) is performed based on the transmitted data to determine whether the data is transmitted correctly, and based on this result. Then, in the next step S ₅₄ , it is checked whether or not there is an error. If there is an error,
To request transmission of data again, but returns to step S ₅₂ after executing the processing (step S ₅₅₎ for transmitting a NACK signal, in the case of no error, the process proceeds to the next step S _56, the transmission data Is received.

That is, flag data transmitted in step S ₅₆ is set to f register, whether the flag data is "1", in other words, whether there is a change in the unit price at POS terminal side is determined (step S ₅₇ ). As a result, if it is determined to be no, the process proceeds to step _S58 , and the transmitted PLU number and number data are respectively stored in the a register and t ₁
It is set in the register. Find the PLU number of the commodity classification by total memory M 'in accordance with the next step S ₅₉ PLU number of the set in a register, the processing for setting the corresponding address data to the b-registers is executed thereby obtained It Then, in the next step S ₆₀ , a process of accumulating the number data in the t ₁ register in the address area M ′ (b) of the total memory addressed by the contents of the b register is executed. Subsequently, the unit price of the address area M ′ (b) is multiplied by the number of t ₁ registers to calculate the total sales amount, and the calculation result data is accumulated as the amount data of the address area M ′ (b) (step S ₆₁ and S ₆₂ ) are executed.

Set the other hand, if the flag data is judged as "1", then the process proceeds to step S _64, transmitted come the PLU number, number data and the total amount data a respective, to t _1, t ₂ register To be done. After this, in steps S ₆₅ and S ₆₆ , the same processes as in steps S ₅₉ and S ₆₀ described above are executed, and then the process _proceeds to step S ₆₇ . In step S ₆₇ , the total amount data in the t ₂ register is accumulated as the amount data in the address area M ′ (b).

After the step S ₆₂ and step S _67, respectively proceeds to step S ₆₃ and step S _68, the contents of RAM2'd is erased. When the processes of steps S ₆₃ and S ₆₈ are completed, AC indicating that the reception process of the transmission data is surely completed
K signal is sent to the POS terminal side (step
S ₆₉ ).

When this process ends, but returns to step S _52, if it is determined that not Here, in the next step S _70, is examined transmission end signal whether the POS terminal side, if this signal is also no , the process returns to step S _52, a standby state until one is present in the data transmission or the transmission end signal. And Thus, if it is determined that "Yes" in step S _70, the process proceeds to the next step S _71, whether or not the determination finished to specify all machines POS terminal side (electronic register Ta～Tk) To be done. Here, if it is determined to be no, the next step
Proceeds to S _72, after executing the process of designating the next machine number, returns to step S _51.

In this way, electronic registers Ta to Tk on the POS terminal side
Is sequentially designated to transmit a data transmission request signal, the data transmitted by this is accumulated in the classification total memory M ′, and the sales data for each product category of each electronic register Ta to Tk is totaled. To be executed.

In the above example, when the unit price is changed on the POS terminal side, the total sales amount is transmitted in addition to the number data, but the changed unit price data and each unit price are used instead of the total sales amount. It is also possible to transmit the number data for each item and calculate the total sales amount on the side of the headquarters center based on the transmitted unit price before and after the change and the number. Further, although the sales data processing device and the data collection device are each an electronic register in the above embodiment, the present invention is not limited to this, and other sales data processing device and data collection device may be used.

[Effect of the Invention] According to the present invention, it is possible to reduce the transmission time when transmitting sales data to the data collection device, and to reduce expenses such as telephone charges.
