Embodiment Construction

[0051]In order to facilitate those of ordinary skill in the art to better understand the essence of the present invention, the specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0052] Example of Electronic Shelf Label Host

[0053] like figure 1 As shown, an electronic price tag host includes: a controller, a Zigbee communication module connected to the controller, a WiFi communication module, a liquid crystal module, an EEPROM module, a FLASH module, an SD_CARD module and a USB serial conversion module.

[0054] Wherein, the controller adopts a 32-bit chip of STM32F103RBT6, which has the advantages of good performance, low price, and wide application range. The chip has 3 serial ports, which can simultaneously meet the communication with the WiFi communication module, Zigbee communication module and the chip itself with the outside world. At the same time, the chip is externally connec...

Abstract

The invention discloses an electronic label host which comprises a controller, a Zigbee communication module, a WiFi communication module, a liquid crystal module, an EEPROM module, a FLASH module, an SD_CARD module and a USB serial port converting module. The modules are connected with the controller. The WiFi communication module and the Zigbee communication module are used for transmitting wireless information. The liquid crystal module is used for displaying information. The problems that a paper label is used for one time, errors can easily happen during replacing, displayed information is single, and losing can happen easily are solved. Meanwhile, the WiFi communication module and the Zigbee communication module are combined, and the manufacturing cost of the electronic label host is effectively controlled. The invention further provides an electronic label slave machine which is matched with the electronic label host for use and an electronic label system which comprises the electronic label host and the electronic label slave machine and is used for a supermarket.

Description

technical field [0001] The invention relates to the technical field of wireless communication equipment, in particular to an electronic price tag technology based on Zigbee communication and WiFi communication. Background technique [0002] Commodity information (price, place of origin, product number, etc.) in the supermarket is mostly displayed by paper cards. The display method of this kind of paper card is one-time use, and every time the product information changes, it will involve a large number of replacements, and it is easy to lose and misplace it, causing unnecessary misunderstanding between merchants and customers. Sometimes when discounts and promotions are required, they cannot be well reflected. [0003] In order to solve the technical problems of complicated, inconvenient and error-prone when changing product information on paper price tags, someone in the industry proposed an electronic price tag system. For example, a Chinese patent with publication number...
