Description

  The present invention relates to an electronic shelf label system that electronically displays data such as product selling prices received from a management device on a shelf label display.

  In recent years, electronic shelf label systems have been introduced in retail stores such as supermarkets. The electronic shelf label system installs a shelf label display that displays the price of the product as electronic data near the product displayed in the store, and stores data such as the selling price as needed from the management device that stores the product information. It is a system that transmits to the bill display and displays it.

  Here, in order for the electronic shelf label system to operate normally, each shelf label display must be able to correctly receive data from the management device. There was the following as a method of checking.

(1) When sending price change data from the management device to the shelf label display, if the shelf label display receives the price change data, an acknowledgment (ACK signal) is sent back, and the management device confirms that The status of each shelf label display is monitored by receiving the response.
(2) Data such as selling price displayed on the shelf label display is repeatedly transmitted from the management device to the shelf label display at a predetermined set time interval, and the shelf label display can receive the data within a predetermined time. If not, the shelf label display notifies an error (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 7-175456

  However, in the above method (1), since the reception state is confirmed only for the shelf label display corresponding to the product whose price has been changed, all the shelf label displays existing in the store are confirmed. There was a problem that I could not.

  In the method (2), since data (sale price, etc.) actually displayed on the shelf label display is transmitted, in the case of a store using a large number of shelf label displays, There is a problem in that it takes a long time to check the reception state because it is necessary to transmit different data corresponding to each display device by the number of shelf label displays. In addition, this method is based on a method in which data is always repeatedly transmitted because it is determined whether or not data can be received within a predetermined time. Therefore, the shelf label display side also has a problem that the number of receptions increases and power consumption also increases. Many shelf label displays are driven by a battery such as a button battery, so that the battery life is shortened and the inconvenience is large.

  The present invention has been made in view of the above points, and an object of the present invention is to provide an electronic shelf label system that displays data such as product selling prices received from a management apparatus on a shelf label display. It is possible to execute the confirmation on all the shelf label displays in the store for a short time and with low power consumption.

  The present invention has been made to solve the above-described problem, and includes a management device that has display means and manages data related to products, and is provided corresponding to the products displayed on a product display shelf, the management device Whether the data transmitted from the management device can be received by the shelf label display device in an electronic shelf label system having a shelf label display device for displaying product information such as the selling price of the product transmitted from Confirmation signal transmitting means for transmitting the same confirmation signal to the plurality of shelf label indicators, and the shelf label for informing that when the confirmation signal is received by the shelf label indicator There is provided an electronic shelf label system characterized by comprising an informing means provided on a display.

  In this invention, the same confirmation signal is transmitted to a plurality of shelf label displays (for example, all shelf label displays in the store), and confirmation signals are sent to the shelf label displays that have received this confirmation signal. A notification is made indicating that the data has been received, that is, data can be received from the management apparatus. Therefore, if the confirmation signal can be received, notification from the notification means is performed. On the other hand, if the confirmation signal is not received, notification is not performed. Therefore, the store clerk checks whether there is notification on the shelf label display, It is possible to grasp the reception status of the shelf label display device.

In addition, since the notification of the availability of the reception state is performed immediately when the confirmation signal is received, the number of receptions at the shelf label display device is smaller than the conventional method of repeatedly transmitting and receiving the confirmation signal. Thus, it is possible to reduce the power consumption of the shelf label display.
In addition, since a common (same) signal is transmitted as a confirmation signal to a plurality of shelf label displays, the confirmation signal is different from the transmission of different actual display data for each shelf label display as in the prior art. It is possible to reduce the time required for transmission to each shelf label display. As a result, the store clerk can perform the work for confirming the reception state of the shelf label display in a short time. Furthermore, since the same confirmation signal is transmitted, it is possible to confirm the reception state for all shelf label displays in the store.

  In the electronic shelf label system, the notification unit is controlled to end the notification after a predetermined time has elapsed.

  According to the present invention, the display returns to the original state after a predetermined time is notified on the shelf label display device that has received the confirmation signal. Therefore, since the operator only needs to perform an operation for starting transmission of the confirmation signal, an operation for ending the notification and returning the display to the original is unnecessary, and the operability is improved. In addition, since the notification end process is automatically performed, it is possible to prevent the shelf label display device from continuing the notification operation indefinitely due to the operator forgetting to perform the notification end operation.

  The electronic shelf label system further comprises means for transmitting a command for terminating the notification by the notification means to the shelf label display.

  According to the present invention, even when an inexperienced store clerk who takes time to check all the shelf label indicators in the store performs the check operation, the notification is performed when the check operation of the store clerk is completed. Since the command to end the process can be transmitted, the store clerk can perform confirmation without hurrying.

  In the electronic shelf label system, the electronic shelf label system further includes setting means for setting a time for executing transmission of the confirmation signal, and time measuring means for measuring the current time, and determines that the time is set by the setting means. In such a case, the display unit is controlled to display a display prompting execution of transmission of the confirmation signal.

  According to the present invention, if a date and time for changing the selling price of a product is set in advance, it is displayed that it is time to send a confirmation signal at that time. Prior to transmission to the shelf label display, the reception status of the shelf label display can be reliably confirmed. This prevents mistakes such as forgetting to check the reception status of the shelf label display and sending price change data even though there is a shelf label display that cannot receive data from the management device. can do.

In the electronic shelf label system, the notification by the notification means is a blinking display on the shelf label display.
In this invention, the display is blinked in a normal shelf label display that has received a confirmation signal, and the display remains unchanged in an abnormal shelf label display that has not received a confirmation signal. It is possible to easily judge whether the shelf label display is good or bad by walking and visually checking.

  Also, in the electronic shelf label system, product information management means for managing product information such as the selling price of a product so as to be changeable and distributing the product information such as the selling price of the changed product to a POS terminal for registering a customer's purchased product. And a display that prompts execution of the transmission of the confirmation signal when the selling price of the product is changed by the product information management unit.

  According to the present invention, when the product price is changed by the product information management means, the transmission of the confirmation signal is prompted by the display. Therefore, according to the display, the shelf label is sent prior to the transmission of the data whose price has been changed to the shelf label display. The reception status of the display can be confirmed reliably. This prevents mistakes such as forgetting to check the reception status of the shelf label display and sending price change data even though there is a shelf label display that cannot receive data from the management device. can do. As a result, it is possible to prevent a problem that the selling price information in the POS terminal does not match the selling price displayed on the shelf label display.

  Also, in the electronic shelf label system, product information management means for managing product information such as the selling price of a product so as to be changeable and distributing the product information such as the selling price of the changed product to a POS terminal for registering a customer's purchased product. When the selling price of the product is changed by the product information management means, the changed product selling price is transmitted to the POS terminal, and the confirmation signal is sent from the confirmation signal transmitting means to the shelf label display. It transmits to a device.

  According to this invention, when the product selling price is changed by the product information management means, a confirmation signal is transmitted to the shelf label display device, so that it is forgotten to confirm the reception state of the shelf label display device, It is possible to prevent the occurrence of a mistake that the selling price change data is transmitted even though there is a shelf label display that cannot receive data. As a result, it is possible to prevent a problem that the selling price information in the POS terminal does not match the selling price displayed on the shelf label display. Further, only the operation for changing the selling price of the product needs to be performed, and the operation for transmitting the confirmation signal is not necessary.

  In the electronic shelf label system, after the confirmation signal is transmitted from the confirmation signal transmission unit to the shelf label display, the product price changed by the product information management unit is transmitted to the shelf label display. It is characterized by that.

  According to the present invention, the selling price change data is transmitted to the shelf label display after confirming the reception state of the shelf label display. In other words, when selling price change data is transmitted, it is possible to ensure that the reception status of all shelf label displays is normal (for example, replace the unreceivable shelf label display with a new one). In addition, the selling price change data can be received by all the shelf label displays. Thereby, the malfunction that the selling price information in a POS terminal and the selling price displayed on a shelf label display device do not correspond can be prevented effectively.

In the electronic shelf label system, the confirmation signal includes two or more character data for distinguishing the confirmation signal from other signals.
According to the present invention, the case where a confirmation signal is transmitted and the case where a signal other than the confirmation signal is transmitted are distinguished by two or more character data included in those signals. The possibility that the confirmation signal is erroneously received due to such an error can be reduced. That is, if the confirmation signal and other signals are distinguished from each other by one character data, the confirmation signal is erroneously received only when the one character becomes an error during transmission. According to the invention, such an error does not occur with an error of only one character.

  ADVANTAGE OF THE INVENTION According to this invention, it is possible to implement | achieve the electronic shelf label system which can perform reception status confirmation with respect to all the shelf label displays in a shop for a short time and low power consumption.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a diagram showing a network configuration of a store in which an electronic shelf label system 10 according to an embodiment of the present invention is introduced. In this store, a POS system 20 for registering and purchasing customers' purchased products is also introduced. The electronic shelf label system 10 and the POS system 20 are connected via a LAN (Local Area Network) 30 in the store. Are connected to each other.

  In FIG. 1, an electronic shelf label system 10 includes a shelf label controller 11, a transceiver 12 that wirelessly transmits data from the shelf label controller 11 to each shelf label display, and a product displayed in the store. It comprises a plurality of shelf label displays 13 provided. The shelf label controller 11 is connected to the LAN 30 and can exchange data such as product files with the store controller 21 on the POS system 20 side. Note that wireless communication between the transceiver 12 and the shelf label display 13 is based on infrared communication in this embodiment, but may be based on other communication methods such as wireless communication. In addition, since infrared rays have directivity and the range in which a transmission signal reaches is limited, the store is divided into a plurality of blocks, and infrared communication with the shelf label display 13 is performed using a plurality of transceivers 12 corresponding to each block. It is preferable to configure the system so that it can be performed without problems.

  The POS system 20 includes a store controller 21 that manages various data such as product files and sales performance files, and a plurality of POS (Point of Sales) terminals 22 that are communicably connected to the store controller 21. The POS terminal 22 is installed in the checkout area of the store in the store, and registers the purchased product of the customer and settles the purchase price by reading the barcode on the product label. The product registration / settlement data is aggregated in the store controller 21. The store controller 21 is configured by incorporating application software for a store controller into a general personal computer.

  FIG. 2 is a diagram showing an appearance of a product display shelf 40 that is installed in a store in a store and displays products. The product display shelf 40 displays products 41 for each type, and a shelf label display 13 is attached at a position corresponding to each product on the front portion of the shelf. The transceiver 12 is installed at a position where infrared communication with the shelf label display 13 can be performed (for example, a ceiling or a wall surface) (not shown in FIG. 2).

FIG. 3 is a front external view of the shelf label display 13, and FIG. 4 is an electrical block diagram of the shelf label display 13.
The shelf label display 13 performs a predetermined operation by a CPU (Central Processing Unit) 131 executing a program in a ROM (Read Only Memory) 132. Data such as product selling price transmitted from the shelf label controller 11 by infrared rays is received by the infrared receiving unit 135. A RAM (random read / write memory) 133 stores a shelf label ID for identifying the shelf label display 13, and the shelf label display 13 discriminates data addressed to itself based on the shelf label ID. It has become. The received data is stored in the RAM 133 and displayed on the display unit 134 (configured by a liquid crystal display, for example). When a confirmation signal transmission text (see FIG. 9), which will be described later, is received, control is performed so that the display of the commodity selling price on the display unit 134 blinks. At this time, the LED lamp 136 is also turned on. Electric power for driving each part of the shelf label display 13 is supplied from the button battery 137.

  In addition, a product information label 138 is attached to the front of the shelf label display 13 so as to notify the customer which product price of the product is displayed on the shelf label display 13. The product information label is made of paper, for example, and has a product name 1381, a shelf label ID 1382, and a barcode 1383 printed thereon. The shelf label ID 1382 is the same as that stored in the RAM 133, and the barcode 1383 is the same as the barcode of the product for which the shelf label display 13 displays the price. The product information label 138 is issued from the label issuing machine 119 by the initialization process in the shelf label controller 11, as will be described later.

  FIG. 5 is an electrical block diagram of the shelf label controller 11. The shelf label controller 11 has a configuration in which an initializer 118 and a label issuing machine 119 are connected to a general personal computer including a CPU 111, a ROM 112, a RAM 113, a hard disk device 114, a display display 115, a keyboard 116, a communication interface 117, and the like. Have. The shelf label controller 11 is operated by executing the built-in application software for a predetermined shelf label controller.

  Here, the initializer 118 and the label issuing machine 119 are devices used for the initialization process of the shelf label display 13. In the initialization process, the shelf label display 13 is brought close to the initializer 118, the shelf label ID is stored in the RAM 133 of the shelf label display 13 by non-contact communication, and the product information label 138 is printed and issued from the label issuing machine 119. For non-contact communication, RF (Radio Frequency) communication or infrared communication can be used. In the case of infrared communication, the above-described infrared receiving unit 135 can be used as a receiver on the shelf label display 13 side. However, in the case of RF communication, a new RF receiver is provided on the shelf label display 13. On the side of the initializer 118, a transmitter (not shown) corresponding to them is provided. Further, the shelf label ID stored in the RAM 133 and other information to be printed on the product information label 138 are specified from the shelf label controller 11 by an operator (operator) instruction.

  FIG. 6 shows an example of a shelf label file. The shelf label file is a database that stores the product code of the product and the shelf label ID of the shelf label display 13 in association with each other, and is stored in the shelf label controller 11. The shelf label controller 11 refers to the shelf label file to determine to which shelf label display 13 the selling price data of each product should be transmitted. Further, at the time of initialization processing, the shelf label ID associated with the product (product code) for which the shelf label display device 13 to be initialized is displayed based on the shelf label file is transferred from the initializer 118 to the shelf label. The data is written in the RAM 133 of the display unit 13.

  7 and 8 show an example of a product file and a special sale file, respectively. These files are created, edited, and changed on the store controller 21 so that the same information is shared between the store controller 21 and the shelf label controller 11. In the product file, the product name, normal price, shelf label ID, etc. are stored for each product code. In the sale file, for each product code of a product to be sold, a product name, a sale price, a sale start date, a sale end date, and the like are stored. On a regular day (other than a special sale day), data on the normal price in the product file is transmitted to the shelf label display 13 of each product, and on a special sale date, the data on the special price in the sale file is transmitted to the shelf label display 13. Is done. As a result, the selling price of each commodity corresponding to the normal day and the special sale day is displayed on the shelf label display 13. The same selling price data is also transmitted to the POS terminal 22 for product registration.

  FIG. 9 is a diagram showing the structure of data (transmission text) transmitted from the shelf label controller 11 to the shelf label display 13. The transmission text includes a general data transmission text (FIG. 9 (a)) for transmitting selling price data and the like at a normal time, and a confirmation signal transmission text (FIG. 9 (FIG. 9) transmitted when confirming the reception state of the shelf label display 13. b)), each of which includes a start code field, a shelf label ID field, and a data field.

  The start code field is a field in which data for determining the type of transmission text is arranged. Data “S2” is used for general data transmission text, and data “S1” is used for confirmation signal transmission text. The shelf label ID field is a field for designating the shelf label display 13 as the transmission destination of the transmission text. Here, the shelf label ID of the shelf label display 13 is described, and the shelf label display 13 having the same shelf label ID as the shelf label ID described in the shelf label ID field receives the data in the data field. It has become. Here, in the confirmation signal transmission text, “00000” is described as the value of the shelf label ID. In this case, all the shelf label displays 13 receive the transmission text. In this case, instead of describing the value “00000” in the shelf label ID field of the confirmation signal transmission text, when the value of the start code field is “S1”, all the shelf label ID fields are not checked. The shelf label display 13 may receive the transmitted text.

  The data field is a field in which the substance of the data to be transmitted is arranged, and the format differs between the general data transmission text and the confirmation signal transmission text. In the general data transmission text, sales price data and the like are described. FIG. 9A shows an example in which data “159” (refer to the sale file in FIG. 8) indicating the sale price of the product “ABC biscuit” is described. On the other hand, in the confirmation signal transmission text, a command “F” for blinking data displayed on the display unit 134 of the shelf label display 13, a parameter value for designating the blinking time, and a command “S” for terminating the blinking. Described. In FIG. 9B, the parameter value for designating the blinking time is “5”. In this case, blinking continues for 5 minutes.

  Next, operation | movement of the electronic shelf label system 10 which has said structure is demonstrated with reference to a flowchart.

(Operation example 1)
10 to 12 show an operation example 1 in which the reception state of the shelf label display 13 in the store is confirmed at a preset time. FIG. 10 is a flowchart of the shelf label controller 11, and FIG. 11 is a flowchart of the shelf label display 13.

  In FIG. 10, the shelf label controller 11 first sets the time for checking the reception status of the shelf label display 13 (step S11). For example, a time when a predetermined time (for example, 30 minutes) has passed since the end of the daily store business hours (closed) or a time before a predetermined time (for example, 30 minutes) before the store business start time is set. This setting is performed by the operator of the shelf label controller 11 using the display 115 and keyboard 116 of the shelf label controller 11. Hereinafter, a case where the time after closing is set will be described.

  The shelf label controller 11 reads the current time from the built-in clock function and determines whether or not the set time has been reached (step S12). When the set time is reached, the shelf label controller 11 performs a display as shown in FIG. 12 urging the operator to confirm the reception state of the shelf label display 13 in the store on the display 115 (step S13). This display includes a message “Closed time. Please check the shelf label display” and an execution button.

  When the operator selects and inputs an execution button, the shelf label controller 11 transmits a confirmation signal transmission text (FIG. 9B) to all shelf label displays 13 in the store (step S14).

  On the other hand, in FIG. 11, the shelf label display 13 checks whether or not the confirmation signal transmission text has been received (step S21). When the confirmation signal transmission text is received, the shelf label display 13 blinks the data displayed on the display unit 134 according to the contents of the data field of the received text (step S22). For example, in the case of the confirmation signal transmission text in FIG. 9B, blinking continues for 5 minutes. Thereafter, when the designated blinking time has elapsed, the shelf label display 13 finishes blinking the display unit 134 and returns the display to the original state (step S23). However, since the abnormal shelf label display cannot receive the confirmation signal transmission text, the display unit 134 does not perform the blinking operation, and the display is normal (NO in step S21).

  Here, the store clerk looks around the store in the store during the blinking time and checks the shelf label display 13 to find a shelf label display that is not blinking, that is, a shelf label display with a poor reception state. This non-flashing shelf label display cannot be received from the shelf label controller 11 and needs to be replaced. The store clerk removes the shelf label display from the merchandise display shelf 40 and replaces it with a new normal shelf label display that has been initialized. In addition, you may make it replace | exchange the shelf label display which does not stop blinking even if blinking time is complete | finished.

In this way, all the shelf label displays 13 in the store are in a normal reception state. After that, if price change data (sale price data if the next day is a special sale date) is transmitted from the shelf label controller 11 to each shelf label display 13, all the shelf label displays 13 change the price without any problem. Data can be received, and correct data can be displayed on the display unit 134.
In this operation example 1, the display data on the shelf label display 13 continues to blink for 5 minutes, and then the blinking is automatically terminated. However, an end button is displayed on the display display 115 of the shelf label controller 11. When the operator operates this end button, a command for ending the blinking of the shelf label display 13 may be transmitted to each shelf label display 13. By doing in this way, even a store clerk who is unfamiliar with the confirmation work of the shelf label display device 13 can perform the confirmation work at his / her own pace without panicking.

(Operation example 2)
FIGS. 13 to 16 show an operation example 2 in which the reception state of the shelf label display 13 is confirmed when the store price is changed by the store controller 21. 13 is a flowchart of the store controller 21, and FIG. 14 is a flowchart of the shelf label controller 11. In this operation example, the operation of the shelf label display 13 is the same as that of the operation example 1, and thus the description thereof is omitted.

  In FIG. 13, when the store closing process is selected by the operator, the store controller 21 starts the store closing process (step S31). In this closing process, setting of the product price for the next day, aggregation of sales performance data for the day from the POS terminal 22 and the like are performed. When setting the product selling price, the operator opens a product file or a special sales file on the store controller 21 to perform editing / changing work.

  Next, if the next day is a special sale date, the store controller 21 transmits special sale file data to the POS terminal 22 and the shelf label controller 11 if it is not a special sale date (step S32). At this time, the POS terminal 22 overwrites and saves the selling price of the corresponding product with the received data, and the shelf label controller 11 temporarily stores the received data until it is transferred to the shelf label display 13 (step S44 in FIG. 14). Keep it. Then, the store controller 21 displays a message “Please send a confirmation signal from the shelf label controller to the shelf label display” as shown in FIG. 15 (step S33).

  14, the shelf label controller 11 receives the commodity price data transmitted in the above step S32 (step S41), and displays a “confirmation signal transmission” button and a “sell price change execution” button on the display 115. Is displayed (step S42). When the operator selects and inputs a “confirmation signal transmission” button, the shelf label controller 11 transmits a confirmation signal transmission text (FIG. 9B) to all shelf label indicators 13 in the store (step S43). .

  By receiving the confirmation signal transmission text, the reception state confirmation of the shelf label display 13 in the store is performed in the same manner as in the operation example 1 described above. After the confirmation of the shelf label display is completed and all the shelf label displays 13 can receive data from the shelf label controller 11, the operator selects the “sell price change execution” button displayed in step S42. input. When this input is made, the shelf label controller 11 transmits the commodity price data stored temporarily (see step S32) to each shelf label display 13 (step S44). Thereby, all the shelf label displays 13 can receive the selling price data without any problem, and correct data is displayed on the display unit 134.

(Operation example 3)
FIGS. 17 to 20 show an operation example 3 in which the confirmation signal transmission text is automatically transmitted to the shelf label display 13 when the store price is changed by the store controller 21. 17 is a flowchart of the store controller 21, and FIG. 18 is a flowchart of the shelf label controller 11. In this operation example, the operation of the shelf label display 13 is the same as that of the operation example 1, and thus the description thereof is omitted.

  In FIG. 17, when the store closing process is selected by the operator, the store controller 21 starts the store closing process (step S51). In this closing process, as in the operation example 2, the setting of the product sales price for the next day, the aggregation of the sales performance data for the day from the POS terminal 22 and the like are performed. When setting the product selling price, the operator opens a product file or a special sales file on the store controller 21 to perform editing / changing work.

  Next, the store controller 21 transmits the data of the special sale file to the POS terminal 22 and the shelf label controller 11 if the next day is the special sale date, and the product file data if it is not the special sale date (step S52). At this time, the POS terminal 22 overwrites and saves the selling price of the corresponding product with the received data, and the shelf label controller 11 temporarily stores the received data until it is transferred to the shelf label display 13 (step S64 in FIG. 18). Keep it. After that, the store controller 21 displays a message “A confirmation signal has been sent to the shelf label display. Please check the shelf label display” as shown in FIG. An instruction command for transmitting the confirmation signal transmission text is transmitted (step S53).

  In FIG. 18, the shelf label controller 11 receives the commodity price data transmitted in step S52 (step S61). Also, the instruction command transmitted in step S53 is received, and a confirmation signal transmission text (FIG. 9B) is transmitted to all the shelf label indicators 13 in the store according to the instruction command (step S62). Thereafter (for example, after the elapse of the blinking time of the shelf label display designated by the confirmation signal transmission text), the “sell price change execution” button is displayed on the display 115 as shown in FIG. 20 (step S63).

  By receiving the confirmation signal transmission text, the reception state confirmation of the shelf label display 13 in the store is performed in the same manner as in the operation example 1 described above. After the confirmation of the shelf label display is completed and all the shelf label displays 13 can receive the data from the shelf label controller 11, the operator selects the “sell price change execution” button displayed in step S63. input. When this input is made, the shelf label controller 11 transmits the commodity price data stored temporarily (see step S52) to each shelf label display 13 (step S64). Thereby, all the shelf label displays 13 can receive the selling price data without any problem, and correct data is displayed on the display unit 134.

As described above, the embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to the above, and various design changes and the like can be made without departing from the scope of the present invention. It is possible to
For example, instead of blinking the display data on the display unit 134 of the shelf label display 13, the LED lamp 136 may be turned on or blinked. Further, instead of blinking the display unit 134, all the digits to be displayed may be the same number, for example, “8”.

  Further, the store controller 21 and the shelf label controller 11 may be integrated.

  Further, a plurality of display units 134 of the shelf label display 13 may be provided, and the normal price and the special sale price may be displayed on each of them.

Further, a sale price change file corresponding to a sale price change including price reduction and price increase as well as special sale, that is, price reduction, may be used as a special sale file.
Further, the normal price and the special sale price of each product are set and stored in the product file without dividing the product file and the special sale file, and the data of the changed product is transmitted to the shelf label display 13 and the POS terminal 22. It may be.
