Description

Detailed Description of the Invention (Industrial Application Field) The present invention connects a plurality of electronic scales having a registration function for each call number through a common bus line, and mutually exchanges the registration data registered in each electronic scale. The present invention relates to an electronic scale control device that can be used for.

(Prior art) An electronic scale includes a weight detection section that measures the weight of an article placed on a weighing pan, a key input section equipped with a numeric keypad and function keys, and a weight value of the article weighed by the weight detection section. The weight value of the weighed article is captured by the display section that displays the weight value of the weighed article, and the label printer that prints the weight value of the article weighed by the weight detection section and the product name of the article, etc. The computer is equipped with an arithmetic control section that performs data transfer, storage of various data, and arithmetic operations.

This type of electronic scale can store various data in advance in a storage unit controlled by an arithmetic control unit, and when weighing an item, first enter a code representing the item using a key input unit. When the article is weighed after inputting data from etc. will be displayed. Further, the printer prints out a label on which the product name, expiration date, processing date, unit price, weight, price, etc. of the product are printed.

In such electronic scales, call numbers are set in advance for frequently used products, and data such as the product code, product name letter code, unit price, etc. for each product can be stored in the storage section using the numeric keypad. Generally, it is registered in a registration memory.

In places with large sales floor areas, such as department stores and supermarkets, multiple electronic scales may be used in the same sales floor. Registration data was registered for each.

(Problems with the prior art) As the registration data for the same product is registered in multiple electronic scales, there is a limit to the number of products that can be registered. Since it is necessary to further calculate the values by hand, it has the disadvantage that it takes a lot of time to calculate sales proceeds and create product management data.

(Purpose of the Invention) The present invention aims to solve such problems by connecting a plurality of electronic scales each having registered data of different products through a common bus line and mutually using the registered data. This system performs weighing processing to enable the registration of a wide variety of products, and also allows the creation of aggregated data for each product using the electronic scale in which the registration data for the product is registered.

(Summary of the Invention) The electronic scale control device of the present invention has a common bus line that connects a plurality of electronic scales in which the product name, unit price, etc. of each product are registered in advance for each call number, and a call number that is input when weighing the product. If the scale is not registered in the electronic scale that weighed the item, the registered data corresponding to the corresponding call number is called from another electronic scale, and the electronic scale on the weighing side determines which electronic scale is the called up electronic scale. The weighing value is stored in the scale, and the price is calculated by multiplying the unit price included in the registered data corresponding to the product to be weighed, and the data for aggregation such as the price is sent to the call number corresponding to the product to be weighed. It is composed of an arithmetic control unit that transmits the total data for each product to the electronic scale in which it is stored and stores the total data for each product.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic diagram of an electronic scale according to the present invention, which includes a weight detection section 1 such as a load cell that measures the weight of a product, and an AD conversion that converts an analog weighing signal obtained by the weight detection section 1 into a digital value. 2, an arithmetic control section 3 consisting of a microcomputer or the like, a display section 4, a printer 5, a storage section 6, a key input section 7 consisting of a numeric keypad, a function key, etc., and a bus line 8.

The storage unit 6 includes a registration memory, a total memory, a setting memory, a scale number memory, etc., and the registration memory stores various data such as a call number, product code, product name character code, and unit for each product. Registered. The total sales amount for each product is totaled and stored in the total memory.

FIG. 2 is an overall configuration diagram of an electronic scale control device according to the present invention, in which a plurality of electronic scales are connected via a common bus line.

The electronic scale with scale number 1 has registered various data for 70 types of products with call numbers 1 to 70.
Various data of 70 types of products with call numbers 71 to 140 are registered in the electronic scale with scale number 2. In the same way, 700 types of products up to the electronic scale with scale number 10 are registered so that they can be identified by their unique call numbers, and each electronic scale is connected by a common bus line 8, so that they can mutually transmit data, It is configured to enable reception.

FIG. 3 is a flowchart showing the processing procedure when mutually calling and responding between the electronic scales.

This flowchart will be explained below.

(1) When weighing a certain product using, for example, an electronic scale with scale number 2, enter the call number corresponding to the product and turn on the call key (step S ₁ ). Next, the registration memory is searched for the call number entered using the numeric keypad (step _S2 ), and the corresponding call number is assigned to the electronic scale (in this case, scale number 2).
(step _S3 ).

(2) If the corresponding call number exists in the electronic scale with scale number 2, for example, transfer the registered data to the setting memory and store it (step
S ₉ ), and store the scale number 2 of the electronic scale in the scale number memory (step S ₁₀ ). Next, the measured value and
The price is calculated by multiplying the product unit price stored in the setting memory (step _S16 ), and a label or receipt is printed (step _S17 ). Next, the content of the scale number memory is checked (step _S18 ), and if it is the current scale number, the price is added and stored in the tally memory corresponding to the calling number (step _S19 ).

(3) When it is determined in step _S3 that the call number corresponding to the product does not exist in the electronic scale with scale number 2, it is checked in step _S4 whether or not the bus line 8 is in communication. If the bus line 8 is open, the process advances to step _S5 , and the scale number is the lowest (in this case, starting with the scale number 1, skipping the scale number 2 of the electronic scale, and proceeding sequentially to the scale number 3...n ) is transmitted to bus line 8.

The response side confirms that there is a scale number signal on the bus line 8 (step P ₁ ), receives the scale number signal from the bus line (step P ₂ ), checks whether the scale number signals match, and selects a no. If so, the process jumps to another step where a match with another scale number is checked, and if YES (step _P3 ), a reception completion signal is sent to the bus line 8 (step _P4 ).

(4) When the calling side receives the reception completion signal (step _S7 ), it transmits the data type code (in this case, the calling number code) and the calling number to the bus line 8 (step _S8 ). The response side confirms that the data type code is present on the bus line 8 (step _P5 ), and receives and stores the data type code and data (calling number) (step _P6 ).
Next, in step _P7 , it is checked which data type code has been received. In this example, since the calling number code has been received, the registration memory is searched by the calling number in step _P8 .

(5) If the calling number does not exist, send a code without calling number to bus line 8 (step
_P11 ) If a calling number exists, the calling number presence code and registration data registered corresponding to this calling number are transmitted to the bus line 8 (step _P10 ). On the calling side, it is checked whether a presence/absence code signal is being received (step _S11 ), and if this signal is being received, if it is a called number presence code, then in step _S13 ,
If there is no code again, the process advances to step _S14 .

(6) In step _S13 , the registration data sent from the electronic scale on the responding side is sent to the calling side (scale number 2).
(electronic scale), and the scale number of the responding electronic scale is stored in the scale number memory.
If it is determined in step _S12 that a signal with a code without a calling number has been received, it is checked in step _S14 whether it is the last scale number, and if the last scale number has not been processed yet, , the process returns to step _S6 to continue processing for the next scale number. If the corresponding call number is not found even after reaching the last scale number, an alarm is displayed indicating that some kind of error has occurred (step _S15 ).

(7) In step _S18 , if it is determined that the content of the scale number memory is that there is no number 2 of the scale being weighed, and that, for example, the electronic scale with the call number is scale number 1, the step S18 is executed. Perform price aggregation processing for S ₂₀ or less. In step _S20 , it is determined whether or not the bus line 8 is in communication. If the bus line 8 is vacant, the scale number stored in the scale number memory is transmitted to the bus line 8 in step _S21 . The response side performs steps _P1 to _P4 again and transmits a reception completion signal to the bus line 8. When the calling side receives the reception completion signal (step _S22 ), it transmits the data type code (price code in this case), price, and calling number to the bus line 8 in step _S23 .

The response side processes steps _P5 and _P6 ,
To determine the data type code in step _P7 , the price code has been sent, so step
At _P12 , the price is added and stored in the tally memory corresponding to the calling number. In other words, the registered data of the product weighed with the electronic scale with scale number 2 is the registered data of the product weighed with scale number 1.
However, by mutually transmitting and receiving signals using the common bus line 8 between the electronic scale with scale number 2 and the electronic scale with scale number 1, the electronic scale with scale number 2 can be used. The scale calculates the price and issues a label, and the electronic scale with scale number 1 can calculate the sales of the product.

Finally, in step _P13 , the response side sends the addition storage completion signal to the bus line, the calling side receives the addition storage completion signal, and the series of operations ends.

In the above explanation, the electronic scale with scale number 1 is called from the electronic scale with scale number 2, but in reality, all the electronic scales in the set have two programs, one for calling and one for response, and each one has two programs for calling and responding. You can freely call and respond to the call.

(Effects of the Invention) As explained above, the present invention registers registration data corresponding to many different types of products in a plurality of electronic scales in advance, and transmits signals using a common bus line. Since the registered data can be received and used mutually, there is no need to register the data of the same product in multiple electronic scales redundantly, and the number of registered products can be increased. In addition, the total addition for each product can be processed by any of the electronic scales forming a set using signals sent and received via the bus line, so sales calculations can be quickly executed. It is possible.

Furthermore, in the present invention, registered data such as the product name and unit price for each product is registered in each electronic scale by call number without duplication, and the desired registration number can be entered and input when weighing the product. If the call number to be weighed is not registered in the electronic scale that weighed, the registered data corresponding to the call number is called from other electronic scales, and when searching for registered data between electronic scales, the call Since it is possible to search by number, data processing in the arithmetic control unit in the electronic scale becomes easier, and memory can be used more effectively.
