10 is an exemplary diagram of display data transmission of the electronic price display system according to an embodiment of the present invention, and FIG. 11 is an exemplary diagram of transmission of display data between the electronic price display repeater and the electronic price display period according to an embodiment of the present invention .

The step of receiving the data signal ( S300 ) will be described with reference to FIGS. 1 to 11 .

First, the repeater 200 may generate a wakeup frame and transmit a wakeup signal including the wakeup frame as a broadcast packet. In contrast, all electronic price indicators connected to the repeater 200 may wake up and respond (S210).

For example, through a wake-up channel, the repeater may transmit a wake-up signal including a wake-up frame once every 300 seconds for 15 seconds.

In this case, in order to prevent collision between wakeup signals in a wireless environment, each repeater may use a method of transmitting its own wakeup signal in different time slots.

For example, the electronic price indicator 100 may receive a wake-up signal including an identification ID from the electronic price display repeater 200 . In this case, when the identification ID included in the wake-up signal matches the self-identification ID, it wakes up and requests data from the electronic price display repeater 200 .

In addition, the electronic price repeater 200 may transmit a wake-up signal including a wake-up frame to a plurality of predetermined electronic price indicators 300 through a predetermined wake-up channel. For example, the wakeup channel may be a transmission channel for the electronic price repeater 200 to transmit to the electronic price indicator 300 in a broadcasting method.

Also, the repeater 200 may transmit a wake-up frame for 15 seconds once every 300 seconds through a wake-up channel.

For example, the wake-up frame (Wake-up Frame) includes a wake-up ID corresponding to the identification ID of the wake-up target device and accurate current time information for correcting an error of the current time in the corresponding electronic price indicator. can

At this time, in order to prevent collision between wake-up frames in a wireless environment, each repeater transmits its own wake-up frame in different time slots. can be used

In addition, the wake-up electronic price indicator 300 may request and receive data from the electronic price display repeater 200 through a predetermined data channel to be distinguished from the wake-up channel. Matters related to the wake-up channel and the data channel may be applied to each embodiment of the present invention.

As described above, after the wakeup signal is transmitted through the wakeup channel, a process of transmitting display data may be performed through the data channel.

Subsequently, when the corresponding electronic price display 300 receives a wake-up signal from the electronic price display repeater 200, a data information request (Data Info. Request) signal is transmitted to the electronic price display repeater 200 and the A data information response (Data Info. Response) signal may be received from the electronic price display repeater 200 (S320).

Here, in the Data Info. Response signal, the data is actually displayed on the display unit of the electronic price indicator along with the total number of data packets to be transmitted, the total data size, the compressed data size, the compression method, and the checksum. Time to Update Image may be included.

Next, the electronic price indicator 300 transmits a data request signal to the electronic price display repeater 200 on the basis of the data information response signal to respond data from the electronic price display repeater 200 A signal may be transmitted (S330).

For example, although there is a slight difference depending on the size of the display unit of the electronic price indicator 300, all data can be transmitted to the electronic price indicator 300 with only one packet transmission due to the limitation of the payload size of the data transmission packet. If there is no data transmission packet by transmitting several times, the repeater 200 can transmit the entire data to the electronic price indicator (300). In this case, information such as the total number of data packets, total data size, compressed data size, and compression method may be transmitted through the data information response signal in advance.

Accordingly, when the capacity of the display data is large, the display data can be divided and transmitted based on the total number of the data packets.

In this way, when the transmission of the display data is completed, the electronic price indicator may transmit an acknowledgment (ACK) signal to the server through a repeater. The server 100 may recognize the completion of transmission of the display data based on the acknowledgment (ACK) signal.

For example, the repeater may transmit a wake-up frame for 15 seconds once every 300 seconds through a wake-up channel.

At this time, in order to prevent collision between wake-up frames in a wireless environment, each repeater transmits its own wake-up frame in different time slots. can be used

7, when the server sends a control signal to change the front page of the electronic price indicator (TAG) to the repeater (Gateway), the repeater (Gateway) wakes up the electronic price indicator (TAG) after a certain period of time It can send a wake-up signal for Here, the wake-up signal may be transmitted periodically. For example, if the transmission period of the wake-up signal is 5 minutes, the update may be performed to change the front page of the electronic price indicator only after a maximum of 5 minutes.

For example, when the electronic price indicator (TAG) receives the wake-up signal and sends a data request, the gateway sees the MAC address of the electronic price indicator and the electronic price indicator stored in the gateway (TAG) If there is information to be updated on the matching electronic price indicator after comparison with the MAC address, the control signal is transmitted to the corresponding electronic price indicator by including the page index in the control signal and mapped to the corresponding page number The displayed page can be displayed by the corresponding electronic price indicator.
