Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a terminal 111 part, a master terminal,
This invention relates to a sales registration system in which a master terminal and satellite terminals are connected via separate transmission lines.

[Prior Art] In shops that are not very large-scale, one master terminal 3 is connected to one terminal control unit 1 via a first transmission line 2, as shown in FIG. One satellite terminal 5 is connected to the master terminal 3 via the second transmission line 4, and the master terminal 3
In some cases, a sales registration system is adopted in which sales registration operations are carried out at two terminals: the satellite terminal 5 and the satellite terminal 5.

In such a sales registration system, the terminal control unit 1 stores product codes for all products sold on the sales floor,
A product master file is provided that stores product data such as product name, *i, number of sales items, sales amount, etc.
A product subfile is formed to store product data, sales numbers, and sales amounts of products with high sales frequency among all products set in the product master file.

Then, when the product code of the product to be sold is entered on the master terminal 3, if this product code exists in the product subfile, the product data such as the product name and unit price of the corresponding product read from this product subfile is used for sales operations. At the same time, sales data such as the number of sales items and sales amount of the corresponding product are added to the number of sales items and sales amount of the corresponding product code in the product subfile. If the corresponding product code is not found in the product subfile, the product data corresponding to this product code is sent to the terminal control unit 1 via the first transmission path 2. Then, sales operations are carried out using the product data read from the product master file of the terminal control unit 1 and sent back to the master terminal 3, and the corresponding sales data is sent to the terminal control 1 and registered in the product master file. do.

Also, when the product code of a sales product is input at satellite terminal 5, this satellite terminal.

Since no product file is provided in the terminal 5, an inquiry is made to the master terminal 3 via the second transmission path 4 for product data of the corresponding product code. If the corresponding product data exists in its own product subfile, the master terminal 3 returns the product data to the satellite terminal 5, and if the corresponding product data does not exist,
Furthermore, an inquiry is made to the terminal control section 1. and,
Sales data of products sold at the satellite terminal 5 is transmitted to the master terminal 3 and registered in the product subfile. If there is no corresponding product code in the product subfile, it is further transmitted to the terminal control unit 1 and registered in the product master file.

By providing a product subfile that stores product data of frequently sold products in the master terminal 3 in this way, it is possible to reduce the number of times product data has to be reconciled.
The processing layer of the terminal control unit 1 can be reduced. Therefore, the processing speed of the entire system can be improved. In addition, instead of connecting the terminal control unit 1, master terminal 3, and satellite terminal 5 in a closed loop, it is possible to connect the first and second terminals separately via the master terminal 3 as shown in the figure.
Since the connection is made via transmission line 2.4, there is no need to control complicated transmission procedures (protocols) on the transmission line, allowing one-to-one transmission, simplifying control of the entire system and reducing manufacturing costs. Can be reduced.

[Problems to be Solved by the Invention] However, the sales registration system configured as described above also has the following problems. In other words, since the satellite terminal 5 exchanges data with the terminal control unit 1 via the master terminal 3, if a failure occurs in the master terminal 3 for some reason, the master terminal 3 Not only this, but also the normal satellite terminal 5 becomes unable to carry out sales operations.

In such a situation, if you remove the failed master terminal 3 and connect the satellite terminal 5 directly to the terminal control unit 1, it is possible to continue sales operations using this satellite terminal 5. Connection change work for the first and second transmission lines 2.4 is performed on each transmission line 2.
Since the number of signal lines constituting 4 is also large, it becomes a very troublesome task, which is a problem that cannot be dealt with at a sales site where quick processing is required.

The present invention has been made based on such circumstances, and its purpose is to provide a connection switch in the master terminal that directly connects the first and second transmission lines as necessary. To provide a sales registration system that can immediately continue sales operations at a satellite terminal even if a failure occurs in a master terminal and improve reliability for customers.

[Means for Solving the Problems] The present invention combines a terminal IIil1wJ section having a product master tough aisle for storing product data of all products and a master terminal for storing product data of frequently sold products into a first terminal. In a sales registration system in which a master terminal and a satellite terminal for inputting sales data of sales products are connected by a transmission path and a second transmission path is connected, the first transmission path and the second transmission path are connected in the mask terminal.
A satellite terminal connection switch is provided for selectively directly connecting the satellite terminal to the transmission line.

In addition to the above invention, in another invention, in a master terminal, one end of an extension transmission line connected to an extension master terminal having almost the same configuration as the master terminal and the first transmission line are selectively connected. It is equipped with a connection switch for an additional master terminal to connect to.

[Operation] With the sales registration system configured in this way, if the master terminal malfunctions for some reason, you can operate the connection switch for the satellite terminal and connect the first
By directly connecting the second transmission line, the satellite terminal and the terminal control section are directly connected, so that sales operations can be continued using this satellite terminal.

In another invention, in addition to the above-mentioned effects, by operating the 2-inch connection for the additional master terminal before starting the sales operation and connecting the additional master terminal and the terminal control section for a certain period of time before the start of the sales operation, It is possible to set (load) the data necessary for sales from the terminal control unit to the additional master terminal in advance.

[Example code] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a schematic configuration of a sales σ record system according to an embodiment. This sales registration system is broadly divided into a terminal control unit 11 having a product master file;
, a master terminal 12 having a product subfile;
A satellite terminal 13 that does not have a product file, an additional master terminal 14 that has almost the same configuration as the master terminal 12, and a first transmission line 15° that connects the terminal control unit 11 and the master terminal 12. A second transmission line 16. It is composed of an additional transmission line 17 that connects the master terminal 12 and an additional master terminal 14.

The terminal control unit 11 has a function of managing sales data for the entire store, and as shown in the figure, it sends control programs, etc. to a CPtJ (central processing unit) 18 that executes arithmetic information processing via a data bus. ROM 19 for storing fixed data. A 20° RAM that temporarily stores variable data such as input sales data.A product master file 21 that stores product data such as product codes, product names, unit prices, and the number of sales items and sales amounts for all products sold at the sales floor for each product code. ．． Product master file 2 if necessary

Circuit 28. A display unit control circuit 30 that sends display data to a display unit 29 that displays sales amounts etc. electronically. A printer control circuit 32 that sends print data to a printer 31 that prints out the sales amount, total amount, etc. on a receipt! , II m.

Further, an in-line control circuit 33 for transmitting data with the terminal control section 11 and an in-line control circuit 34 for transmitting data with the satellite terminal 13 are connected to the CPU 24 via a data bus. The first transmission line 15 connected to the terminal control unit 11 connects to an extension master terminal connection switch (hereinafter abbreviated as extension switch) formed by a slide type switch via a connector 35a attached to the casing of the master terminal 12. ) 36 common terminal C.

The normally open terminal of this extension switch 36 is connected to the extension transmission line 17 connected to the extension master terminal 14 via a connector 35b also attached to the housing.

Furthermore, the normally open terminal a of the expansion switch 36 is connected to the upper common terminal C of the satellite terminal connection switch (hereinafter abbreviated as a changeover switch) 37 formed by two slide type switches, and the normally open terminal a is connected to the inline burial circuit 33.

On the other hand, the lower normally open terminal a' of the changeover switch 37 is connected to the other inline control circuit 34, and the lower common terminal C' is connected to the satellite terminal 13 via a connector 35c attached to the housing. Connected second transmission line 1
6.

Further, the upper normally open terminal b' is short-circuited to the lower normally open terminal b'. Note that this changeover switch 37 is an interlocking type, so the upper contact bar and the lower contact bar are interlocked, and when the upper contact bar is moved, the lower contact bar is also moved in the same direction. .

Further, the satellite terminal 13 is configured to be able to carry out actual sales operations in the same manner as the master terminal 12, but no product file for storing product data etc. is formed in its own storage unit. At the time of sales registration, the second transmission path 16 is used for the product codes of all sales products.
An inquiry about product data is made to the master terminal 12 via.

Further, the additional master terminal 14 has almost the same functions as the master terminal 12.

However, the additional switch 36 in the master terminal 12. Changeover switch 37 and inline control circuit 34
is not included. Therefore, the additional transmission line 17 is directly connected to the inline control circuit 33.

In the sales registration system configured as described above, during normal sales registration, the contact bar of the extension switch 36 and the contact bar of the changeover switch 37 are connected to the normally closed terminal a (a') side as shown in the figure. . In this state, the first transmission line 15 is connected to the inline system circuit 33 of the master terminal 12 via the expansion switch 36 and the changeover switch 37, and the second transmission line 15 is
7 is connected to the other in-line control circuit 34 via a changeover switch 37.

In this state, similarly to the conventional sales registration system shown in FIG.
When the product code of the sales product is entered from 7, the product subfile in the RAM 26 is searched using this product code. If a product code exists, sales registration operations are executed using the product data read from this product subfile, and the number of items sold, sales amount, etc. are cumulatively registered in the product subfile. In addition, if the corresponding product code is not found in the product subfile, the product data corresponding to this product code is transmitted to the terminal control unit 1 via the first transmission path 15.
Make time for 1. Then, sales operations are carried out using the product data that is successively output from the product master file 21 of the terminal control unit 11 and sent back to the master terminal 12, and the corresponding sales data is transferred to the terminal system tl111.
and register it in the product master file 21.

Further, when a product code of a sales product is input at the satellite terminal 13, an inquiry is made to the master terminal 12 via the second transmission path 16 for product data of the corresponding product code. If the corresponding product data exists in the product subfile of the RAM 26, the master terminal 13 returns the product data to the satellite terminal 13, and if the corresponding product data does not exist, it also makes an inquiry to the terminal control unit 11. Sales data of products sold at the satellite terminal 13 is then transmitted to the master terminal 3 and registered in the product subfile. Note that if the product subfile does not contain the corresponding product code, it is further transmitted to the terminal control unit 11 and registered in the product master file 21.

Next, if the master terminal 12 fails for some reason, the cashier moves the contact bar of the changeover switch 37 to the normally open terminal b(t)'). Then, each inline ll al1 of the failed master terminal 12
Circuits 33, 34 are disconnected from the first and second transmission lines 15, 16. At the same time, the first transmission line 15 and the second transmission line 16 are directly connected via the changeover switch 37. Therefore, satellite terminal 13 and terminal il
111 section 11 will be directly connected.

In this state, when the product code of a sales product is input on the satellite terminal 13, this product code is not input to the inline control circuit 34 of the master terminal 12, but is directly sent to the inline ill i i of the terminal control unit 11.
The signal is input to the l1 section 23. Terminal control 081111
Searches the product master file 21 using the make-order product code input to the inline control circuit 23 to find the product name of the corresponding product code.

Read product data such as unit price and inline III 'a
It is output to the first transmission line 15 via the circuit 23. Then, the satellite terminal 13 executes sales operations using the product data input via the first and second transmission paths 15 and 16, and also transfers sales data such as the number of items sold and the sales amount The data is sent to the terminal III i11 section 11 via the transmission line 16.15. The terminal control unit 11 cumulatively registers the input sales data in the product master file 21.

In this way, even if the master terminal 12 breaks down for some reason, the cashier can switch the changeover switch 37 to the normally open terminal b (b') side, and the satellite terminal 12 and terminal control section 11 can be connected to each other. is connected directly, so satellite terminal 1
2, it is possible to immediately continue normal sales operations.

Moreover, since the time during which sales operations are interrupted due to a failure of the master terminal 12 is only the time required for switching the changeover switch 37, the reliability of the entire system can be improved without causing inconvenience to customers.

Additionally, if the sales floor is expanded or the number of customers increases, it is necessary to add more terminals. In this case, since protocol control is not performed in this system as described above, sales operations cannot be performed with the additional terminal connected to the master terminal 12 or the terminal control unit 11. Therefore, in this case, the expansion switch 36 is switched to the normally open terminal side before the start of the day's sales work.

Then, additional terminal 14 and terminal II 8 part 11
are directly connected. Fixed data necessary for sales operations is then sent from the terminal control unit 11 to the additional master terminal 14. The fixed data necessary for this sales operation includes, for example, product data such as a product code, product name, unit price, etc. that is set in advance in a product subfile formed in the RAM of the expansion master terminal 14.

When the setting process (loading) of fixed data to the extension master terminal 14 is completed, the extension switch 36 is returned to the original normally closed terminal a side, and the extension master terminal 14 is disconnected from the terminal control unit 11. Then, this additional master terminal 14 can execute sales registration work only for products corresponding to the product data set in the product subfile formed in its own RAM. Note that, like the product subfile of the master terminal 12, the product subfile provided in this additional master terminal 14 contains product data for frequently sold products, so most of the products sold to customers are stored in the product subfile. can conduct sales operations using this expanded master terminal 14. Therefore, the additional master terminal 14 can be easily operated under substantially the same conditions as the master terminal 12, if necessary, without employing complicated protocol control.

[Effects of the Invention] As described above, according to the present invention, a connection switch is provided in the master terminal to directly connect the first and second transmission paths as necessary.

Therefore, even if a failure occurs in the master terminal, sales operations can be immediately continued at the satellite terminal, improving the reliability of the entire system.

Additionally, an additional master terminal can be easily installed without affecting the master terminal and satellite terminals.
