Description

Electronic Shelf Label and Control Method {AN ELECTRONIC SHELF LABEL AND A CONTROLLING METHOD THEREOF}

The present invention relates to an electronic shelf label and a control method thereof. More specifically, the present invention relates to a method for reducing battery consumption of an electronic shelf label. In the related art, the electronic shelf label periodically transmits an alive signal to a server, but stops alive signal transmission during a business closing time. It provides a way to reduce the cost and extend the battery life of electronic shelf labels.

Recently, stores such as hypermarkets have been using electronic shelf label (ESL) to display price information. Electronic shelf label is a system that displays information such as real-time price information, price per unit, barcode, etc. of tens of thousands of products displayed in a large mart or convenience store on an electronic label of a display stand. In Europe, the use of such electronic shelf labels is common, but most domestic retail stores still use paper price tags instead of electronic labels. In the coming years, however, electronic shelf labels will replace paper price tags.

The electronic shelf label periodically sends an alive signal to the server so that the server can check the status of each electronic shelf label.

On the other hand, in the case of a general store, when the business hours are over, the entire store is turned off. The electronic shelf label uses a built-in battery without an external power supply, and conventionally, even when the business hours expire, the alive signal transmission continues to consume the battery.

Electronic shelf labels can be used for two to three years with a single battery installed, so it's also a good idea to reduce trace battery consumption.

An object of the present invention is to provide a method for extending the battery life by stopping the alive signal transmission of the electronic shelf label when the store is closed.

According to one embodiment of the invention, there is provided an electronic shelf label installed on the shelf of the store to display information about the goods. The electronic shelf label may include: a communication module configured to receive data to be displayed from a server, a business end signal, and business start time information, and periodically transmit an alive signal to the server; A display for displaying the received data; A memory for receiving the received data and information about the business hours; A power supply unit supplying power; And a control unit for synchronizing time with the server, stopping transmission of the alive signal when receiving a business end signal from the server, and resuming transmission of the alive signal when the business start time arrives.

According to an embodiment of the present invention, there is provided a control method of an electronic shelf label installed on a shelf of a store to display information about a product. The method includes synchronizing time with a server; Periodically sending an alive signal to the server; Receiving a business closing signal and business start time information from a server; Stopping transmission of the alive signal; And resuming transmission of the alive signal when the business start time comes.

According to the present invention, when the operation of the store where the electronic shelf label is installed is terminated, the alive signal transmission of the electronic shelf label can be stopped, thereby extending the battery life and consequently reducing the management cost of the electronic shelf label.

1 is a network diagram of an electronic shelf label system according to an embodiment of the present invention.

Referring to FIG. 1, an electronic shelf label 30 (ESL terminal) is mounted on a shelf of a store such as a large mart or a general store to display product information such as a price. The electronic shelf label 30 communicates with the server 10 via a gateway in the vicinity of the plurality of gateways 20.

A console is connected to the server 10, and the store manager may control the server 10 through the console, and control the gateway 20 and the electronic shelf label 30 that communicate with the server 10.

The store manager transmits information of goods to be displayed on the electronic shelf label 30 through the server 10, such as price, product image, discount information, bar code, and the like, to be displayed on the electronic shelf label 30. 2 illustrates an example of the electronic shelf label 30, and as shown in FIG. 2, a product name, a price, a barcode, and the like may be displayed on the electronic shelf label 30, and the image or information to be displayed may be a server ( 10).

The server 10 and the gateway 20 may be connected by wire or wirelessly, for example, may communicate through Ethernet or Wi-Fi.

The gateway 20 and the electronic shelf label 30 may be wirelessly connected, for example, by ZigBee, Wi-Fi, and UWB (Ultran Wide Band) communication.

The electronic shelf label 30 operates as a built-in power supply and displays data received from the server 10. The electronic shelf label 30 may be equipped with a display that consumes power only when changing the displayed image, such as a bitstable cholesteric display (BCD) or an electronic ink display. In addition, the electronic shelf label 30 periodically transmits an alive signal to the server 10, and the server 10 manager may determine whether the electronic shelf label 30 operates normally through the received alive signal.

Each of the electronic shelf labels 30 has unique identification information (ID), and the server 10 may use the unique ID as an address when communicating with the electronic shelf label 30.

The unique ID is set when the store manager first installs the electronic shelf label 30 on the shelf of the store. The store manager assigns a unique ID to the electronic shelf label 30 using the handheld device and registers it with the server 10 as well.

Once the electronic shelf label 30 is registered with the server 10, the store manager changes the image displayed on the electronic shelf label 30 via the server 10, and transmits various control commands to the electronic shelf label 30. ) Can be controlled.

On the other hand, stores such as large marts, general stores, etc. are usually established in the store opening hours, the electronic shelf label 30 does not need to operate when the store is closed. Since the electronic shelf label 30 operates as a power supply, it is necessary to stop the operation to reduce power supply consumption when the store business is closed. In particular, it is preferable to stop the operation of periodically sending the alive signal to the server 10.

3 shows a configuration of an electronic shelf label 30 according to an embodiment of the present invention.

As shown in FIG. 3, the electronic shelf label 30 according to an embodiment of the present invention receives data to be displayed from the server 10, a business end signal, and business start time information, and transmits the information to the server 10. A communication module 32 for periodically sending an alive signal, a display 38 for displaying the received data, a memory 34 for receiving information on the received data and the business hours, a power supply for supplying power 40 and synchronize the time with the server 10, and upon receiving the business end signal from the server 10, stops the transmission of the alive signal, and resumes the transmission of the alive signal when the business start time arrives. The control unit 36 is configured.

The communication module 32 communicates with the server 10 via the gateway 20 of FIG. 1 and may be a Zigbee communication module, a Wi-Fi communication module, or a UWB communication module which is a short range communication module.

The display 38 may use any display, but is preferably a display that consumes very little power to reduce power consumption and consumes power only when updating the displayed image, such as a Vicetable cholesteric (BCD) display or Electronic ink displays can be used.

The memory 34 stores command codes for controlling the operation of the controller 36 and also stores data received from the server 10. The memory 34 may use any storage device such as a flash memory or an EEPROM.

The battery may be used as the power supply 40.

4 is a diagram illustrating an operation of an electronic shelf label system according to an embodiment of the present invention according to a timeline.

First, the store manager may input a store end time and a start time to the server 10.

Then, at time A, server 10 sends time information to gateway 20 and electronic shelf label 30, and at time B, gateway 20 and electronic shelf label 30 receive the received time information. Synchronize the time with the server 10 based on.

At time C, server 10 sends a business start time and end time to gateway 20.

At time D, the electronic shelf label 30 periodically sends an alive signal through the gateway 20 to the server 10.

When the business close time comes, at time E, the gateway 20 sends a business close message and the next business start time to the electronic shelf label 30.

At time F, electronic shelf label 30 stops transmitting the alive signal, preferably suspends all operations in addition to the timer and enters sleep mode.

When the business start time comes, the electronic shelf label 30 automatically wakes up from the sleep mode and resumes the alive signal transmission at time G.

5 is a flowchart illustrating a control method performed on the electronic shelf label 30 according to an embodiment of the present invention.

In step S11, the electronic shelf label 30 synchronizes time with the server 10 based on the time information received from the server 10. As mentioned above, the electronic shelf label 30 is connected with the server 10 through the gateway 20, and the gateway 20 also synchronizes time.
