Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless shelf label display change system for displaying information such as the price of each product near each product by wirelessly transmitting product information from a server to a shelf label display. The present invention relates to a wireless shelf label display change system used in a store where a change in shelf layout is frequently performed.

[0002]

2. Description of the Related Art In recent years, in stores such as supermarkets and convenience stores, so-called POS (P
(Point of Sales) system is widely used. This POS system mainly includes a plurality of POS terminals (registers) and a store controller placed in a backyard, and the store controller uses the input operation at the POS terminal when selling products to store the data of the sold products. This is a system for displaying and counting data. In this POS system, since the product management is performed by using the product code (bar code) attached to the product, the product code can be linked to information on the product such as the price.
There is no need to put a price tag on each product. For this reason, PO
In a store that employs the S system, a shelf label indicating the price of a product is placed on a shelf where the product is displayed, so that the price of the product is indicated to the customer.

Recently, in addition to the POS system, an ESL system (Electric Shelf Lab) has been proposed.
el System (electronic shelf label system). In this ESL system, the transceiver installed in the store and the ESL attached to each product
(Electronic shelf label) by radio, and each ESL is linked to a store controller or a head office computer (a computer of a chain head office that coordinates a plurality of stores) via a server connected to a transceiver. Here, the server obtains information on the product in the product master from the store controller or the like, transmits the information to the ESL, and displays the product price or the like on the ESL. Therefore, this E
If the SL system is used, the actual sales amount (hereinafter, referred to as an actual selling price) at the POS terminal and the displayed amount of the ESL of each product (hereinafter, referred to as a displayed selling price) can be automatically matched. This eliminates the hassle of replacing paper shelf labels at the time of bargain sale, etc., and the actual selling price matches the displayed selling price of the shelf label due to a mistake in replacing the shelf label or the time difference between the actual selling price change and the replacement of the shelf label. It is possible to minimize problems such as the occurrence of a state in which the customer does not work and the customer's credibility is lost.

[0004] The product master is a set of information (data) related to products, and has data such as a product code, a product name, a normal price, and a special sale price for each product.

[0005]

Conventionally, a transceiver, which is a transceiver that directly communicates with each ESL attached to a shelf on which a product is displayed, is fixed to a ceiling at an appropriate interval in a store. Infrared communication is often used as a communication means, and the communication area that one transceiver can cover is limited. This is because directivity cannot be sharply narrowed down because ESLs are scattered in various places in the store.

[0006] For this reason, usually, a plurality of transceivers are installed on the ceiling of a store so that the inside of the store enters the communicable area of the transceiver. However, at the stage of introducing and installing the ESL system in the store, even if all the places in the store where the products are displayed are in the communicable area of the transceiver, the shelf layout is redesigned in the store thereafter,
If a decoration such as a Christmas tree is temporarily installed, a shelf or a decoration may block infrared communication. In other words, even if there is no area in the store where transceivers are properly placed at the time of introduction and installation of the ESL system, and there is no area where communication failure occurs in the store, if there is a subsequent pattern change in the store, there will be an area where communication will be shadowed. Communication between the ESL located in the area and the transceiver becomes impossible.

In such a case, it is necessary to add a transceiver at a position where communication can be performed with an area in which communication failure occurs due to pattern change or the like.
However, to install a transceiver on the ceiling,
Construction work such as drilling holes in the ceiling and wiring cables is required, and construction work can only be performed at night, after business hours of the store. For this reason, even if it is decided to increase the number of transceivers at a high cost, it is difficult to immediately eliminate the inability to communicate. In other words, while the transceiver is being expanded, the display of the ESL in the area cannot be controlled. Further, in the case of temporarily installing decorations in a store, it is inefficient and not practical to add transceivers each time.

An object of the present invention is to eliminate an ESL (shelf label display) communication failure caused by remodeling of a store or temporary installation of decorations without adding a transceiver (transceiver). (Wireless shelf label display change system).

That is, when the product information is updated in the product master file 3a after the special sale period or after the special sale period ends, the product information file 48 of the ESL server 11 is automatically updated accordingly. Then, when the information of the product information file 48 is updated, the ESL server 11 sends the corresponding ESL 14 via the base station 12 and the transceiver 13.
Send the product information change to.

(Transceiver) Transceiver 13
Is a wireless transceiver having both a function of transmitting to the ESL 14 and a function of receiving a feedback signal from the ESL 14, and wirelessly transmits product information held by the ESL server 11 to each of the ESLs 14 using infrared rays.
The feedback signal from the SL 14 is received and transmitted to the ESL server 11. Since the transceiver 13 needs to communicate with an unspecified number of ESLs 14, the transceiver 13 is omnidirectional, and the reach of infrared rays is limited.
In consideration of this, the transceiver 13 is connected to each ESL.
14 is fixed to the ceiling in the store 90 at a predetermined interval so that the data can be reliably transmitted to the store 14. Specifically, as shown in FIG. 2, it is attached to the ceiling of the sales floor of the store 90 for each section. Here, 12 transceivers 1
3 is attached.

A store 90 shown in FIG. 2 is a simplified representation of a general supermarket, and includes an entrance 91, an exit 92, a showcase 93 at a fresh food section, shelves 94a, 94b, 94c at a general commodity section, and a cash register. 95, a back room 98 and the like. The above-mentioned ECR 6 is arranged in each cash register 95. The ESL server 11 is installed in a room 99 provided in a part of the back room 98.

(ESL) The ESL 14 includes a showcase 93 and shelves 94a, 94 at a sales floor in a store 90 shown in FIG.
b, 94c, which are arranged in the vicinity of each commodity displayed, and replace the conventional paper price tag. The size and shape of the ESL 14 can be selected to some extent according to the sales floor and the product. ESL14 is
As shown in FIG.
7, a solar cell 21, a wireless receiving unit 22, a wireless transmitting unit 23, and labels 25 and 26. Label 25
Is a product name printed thereon, and is attached to the lower left side of the front surface of the ESL 14 as shown in FIG. Label 26 is
A bar code (first bar code) including the company's product code is printed, and is attached to the lower right side of the front surface of the ESL 14.

The ESL 14 has a small CPU inside, and has a receiving function, in addition to a function of displaying information on products.
It has a comparison function and a transmission function. An ESL code unique to the ESL 14 is stored in the internal memory of the ESL 14, and the ESL code included in the product information from the transceiver 13 (or the repeater 15) received by the wireless receiving unit 22 is set to the ESL code which is set to itself. After the comparison, the selling price, the unit price and the like received when they match are updated and displayed on the display units 31 to 37. In this case, the previously displayed product information is cleared, and new product information is stored in the internal memory. Also, after receiving the product information from the transceiver 13 and updating the display,
The ESL 14 transmits a feedback signal (reply) indicating that the processing has been normally completed from the wireless transmission unit 23 to the transceiver 13.

(Repeater) The repeater 15 changes the infrared communication environment by changing the shelf layout or installing a Christmas tree or a decoration for Tanabata for a limited time in a store, and changes the ESL 1 in a predetermined area.
4 is provided for additional or temporary installation when communication between the transceiver 4 and the transceiver 13 becomes impossible. Therefore, the repeater 15 is designed so that it can be easily attached to and detached from the shelves and other structures of the store, and has a smaller size and a smaller output than the transceiver 13. For this reason, when the area where communication failure occurs due to a change in the shelf layout or the like is large, it is necessary to install a plurality of repeaters 15. Due to the limitation, the installation of the repeater 15 is less expensive and takes less time than the additional transceiver 13.

The repeater 15 includes the transceiver 1
3 receives the transmission data sent to the ESL 14 and sends the transmission data to the ESL 14 in an area where the infrared rays from the transceiver 13 do not directly reach. The repeater 15 relays the feedback signal from the ESL 14 to the transceiver 13. Further, since communication is performed in a limited area in which a good communication state cannot be maintained by the transceiver 13 alone, a repeater 15 having directivity is used.

<Overview of Operation of ESL System> In the ESL system 10 having such a configuration, the ESL server 1
The HDD 44 stores information obtained by adding an ESL code for specifying the ESL 14 to information from the product master file 3 a of the store controller 3 as a product information file 48.
(See FIG. 3). This product information file 48
Is immediately updated according to the update of the product master file 3a as described above.

According to a change instruction of the product master file 3a from the headquarters of the chain or a sales strategy at each store, a predetermined product becomes a bargain and the actual selling price decreases, or a bargain product is returned to the normal selling price. When the actual selling price increases, the information of the product held in the product master file 3a is changed, and the content of the product information file 48 of the ESL server 11 is changed accordingly.

Then, the ESL server 11 transmits the product information to the ESL 14 to change the display.
Each ESL 14 compares the ESL code included in the product information received from the transceiver 13 with the ESL code set for itself, and if they match, fetches the product information and updates the actual selling price and unit price. Is displayed on each of the display units 31 to 37.

In this manner, each ESL 14 displays information such as the selling price and the special sale of the displayed product. <Additional Installation and Temporary Installation of Repeaters in ESL System> As shown in FIG.
They are arranged so as not to overlap with 94b and 94c. When this is viewed from the side, it is in a state as shown in FIG. 6, and each shelf 94a, 94b, 94c and showcase 93
The infrared communication between the ESL 14 and the transceiver 13 attached to the vicinity of the product in the above is performed well.

(Additional installation of repeater) The ESL 14 and the transceiver 1 are changed by changing the shelf layout at the store.
When an area that interferes with the communication with the E.3 occurs, the repeater 15 is added to the ESL system 10. For example, the shelves 94a, 94b, 94c arranged at the position shown in FIG. 2 are moved to the position shown in FIG.
Is changed into a store, the infrared rays from the transceiver 13 do not reach the ESL 14 in the area S1 indicated by the oblique grid lines in FIGS. 7 and 8. That is, even if the product information in the product information file 48 of the ESL server 11 is changed, the display of the ESL 14 in the area S1 does not change.

In such a case, the ESL server 11
Recognizes that the ESL 14 that does not return a feedback signal despite transmitting the change of the product information is concentrated in a specific area S1, specifies the area S1, and displays a warning screen on the display screen 45. Then, a message prompting the system administrator to install the repeater 15 is presented. In addition, a similar warning and a message urging the installation of the repeater 15 are printed out on the printer 8. At this time, the ESL server 11 informs the ESL 14 that the feedback signal has not been returned,
The system administrator can specify the area S1 based on the history of whether or not the feedback signal has been returned via the interface 3 or display and output the product name of the product with the ESL 14 to which the feedback signal has not returned, thereby allowing the system administrator to specify the area S1.
Tell the location of 1.

The system administrator determines by himself or herself that the predetermined area S1 has come out of the communicable area of the transceiver 13 by the suggestion from the ESL server 11 or by the change of the shelf layout.
Repeater 1 to enable communication of ESL14
5 is installed. Repeater 15 is transceiver 13
What is necessary is just to install in the place which can communicate with ESL14 in the area S1, and can be installed on the shelf 94b as shown in FIG. 9 and FIG. As a result, the ESL 14 in the area S1 indicated by the oblique grid lines in FIGS.
Although it is not possible to communicate with No. 3, communication becomes possible via the repeater 15, and the display is changed following the change of the product information in the ESL server 11 as before the shelf layout change.

(Temporary Installation of Repeaters) In a store, if an ornament that becomes an obstacle to infrared communication is temporarily installed and an area that interferes with communication between the ESL 14 and the transceiver 13 occurs, the ESL system 10 The repeater 15 is temporarily added. For example, the store layout which was in the state shown in FIG. 9 was changed to make the display stand 93a of fruits and vegetables smaller as shown in FIG.
Is installed, direct infrared rays from the transceiver 13 do not reach the ESL 14 in the area S2 indicated by the oblique grid lines in FIGS.

In such a case, the ESL server 11
A specific area S where the ESL 14 does not return a feedback signal even though the product information change is transmitted
Recognizing that the user is concentrated on the area 2, the area S2 is identified, a warning screen is displayed on the display screen 45, and a message urging the system administrator to install the repeater 15 is presented.
Also, the same warning and repeater 1
Print out a message prompting the installation of 5.

The system administrator determines by himself or herself that the predetermined area S2 has come out of the communicable area of the transceiver 13 by the suggestion from the ESL server 11 or the installation of the Christmas tree T. The repeater 15 is installed in order to enable communication. The repeater 15 can communicate with the transceiver 13 and has the ESL1 in the area S2.
4 may be installed in a place where communication is possible with, for example, the shelf 9 of the Christmas tree T as shown in FIGS.
4c side is installed. As a result, the ESL 14 located in the area S2 cannot communicate with the transceiver 13 directly, but can communicate via the repeater 15, and the ESL 14 is in the same state as before the Christmas tree T was installed.
The display is changed following the change of the product information in the SL server 11.

<Features of the present system> (1) The product information in the product information file 48 of the ESL server 11 is linked to the product information in the product master file 3a of the store controller 3, and displayed on the ESL 14 and the actual selling price used in the ECR 6. Since the displayed selling price automatically matches, the confidence of the shopper in the store is improved. That is, if the selling price at ECR6 is higher than the displayed price at the counter, it is a complaint from the shopper, and if this occurs in the checkout line, all the shoppers in the row will receive a complaint. You will have distrust in the store. However, since the ESL system 10 as described above is introduced in the store management system, the change in the selling price in the product master file 3a and the change in the displaying price in the ESL 14 are automatically linked, and the selling price in the ECR 6 and the selling price in the sales floor are changed. The displayed selling price of the ESL 14 immediately matches. Therefore, shoppers can trust the store.

Further, it becomes possible for a store manager, a section manager, a buyer, and the like to judge a shopper's request and execute a bargain sale and measure the result in real time. (2) In the ESL system 10, the transceiver 13 fixed on the ceiling of the store transmits and receives the ESL 14 in principle. However, the layout of the store is changed, the decoration is installed, and the like. When it comes out of the possible area, the repeater 15 is additionally installed to secure infrared communication. For this reason, even when the layout of the store is changed, it is not necessary to move or add the transceiver 13 which is firmly fixed to the ceiling and whose position is difficult to change. Further, since the repeater 15 is designed to be smaller and more easily detachable than the transceiver 13, additional installation is easier than the transceiver 13, and the cost of the additional installation can be suppressed.

[0043]

According to the present invention, even when a predetermined area is deviated from the communicable area of the transceiver after the transceiver is installed in the shop and the rearrangement in the shop or the like is performed,
If a transmission / reception auxiliary device that relays communication between the shelf label display and the transceiver in the predetermined area is installed, a communication failure with the transceiver can occur without moving or adding the transceiver. Area can be placed in a communicable state.
