Example Embodiment

[0010] In order to better understand the present invention, the present invention will be further explained below in conjunction with the accompanying drawings.

[0011] figure 1 Shows the structure diagram of the electronic shelf label terminal of the present invention. The electronic shelf label terminal consists of a microcontroller, a display screen, a self-wake-up control module and a wireless radio frequency transceiver module. The microcontroller is responsible for the overall control of the terminal, including data reception and analysis, and the drive of the electronic paper display. The self-wake-up control module is responsible for regularly waking up the radio frequency transceiver module to detect the wake-up signal and wake up the microcontroller to update the electronic paper display. The radio frequency transceiver module is responsible for receiving and sending actual data. The electronic paper display is responsible for displaying the price information of the ...

Abstract

The invention provides a new radio frequency self-awakening communication method applied to electronic shelf label systems, wherein in the communication method, an independent self-awakening control function is added to control a sleeping status and a working status of a radio frequency transceiving module and a microcontroller; when both the radio frequency transceiving module and the microcontroller are in the sleep status, only the self-awakening control function is remained, and the function consumes extremely low power. Therefore, the method is capable of greatly prolonging the service life of an electronic shelf label terminal so as to reduce the use cost of the electronic shelf label system.

Description

technical field [0001] The invention relates to a communication method for reducing power consumption of a radio frequency communication system, and is especially suitable for an electronic shelf label system using radio frequency communication. Background technique [0002] With the continuous development of the retail industry, there are more and more types of products and more frequent promotional activities, and the demand for management and replacement of product electronic shelf labels continues to increase. However, the substantial increase in labor costs and the cost of paper electronic shelf labels has brought resistance to the development of the retail industry. Now, with the application of wireless technology, there is an electronic shelf label system used to replace paper electronic shelf labels. This system can accurately modify and display the price of goods in real time. For example, in the patent document with the announcement number CN201876908U, an electro...
