Specifically, the electronic price tag in this embodiment is a low power consumption product, and is periodically in an active state and a dormant state during operation, that is, in a periodic cycle state of "active state-dormant state-active state-dormant state", in order to save energy consumption of the electronic price tag, the time that the electronic price tag is in the active state is usually only several tens of milliseconds, and the time that the electronic price tag is in the dormant state is usually several tens of seconds.
In the using process of the electronic price tag, the electronic price tag needs to be applied to other equipment such as a server and a base station, and the electronic price tag needs to be in data communication with the server through the base station to complete the display of commodity information. In many large supermarkets or large drug stores, the working efficiency of one base station is limited, and a plurality of base stations are often used at the same time to ensure the normal use of the electronic price tags. At this time, the electronic price tag needs to be networked, and the electronic price tag is distributed to the base station.
In this embodiment, when the electronic price that is not networked is in an active state, a heartbeat data packet of the electronic price that is not networked is actively broadcasted, where the heartbeat data packet includes identification information of the electronic price and a networking request instruction of the electronic price.

As shown in fig. 4, the cloud end establishes communication with the base station through a switch poe (power Over ethernet), when an electronic price tag needs to be provided for a certain commodity, a worker may scan a barcode of the commodity with a handheld terminal (PDA), obtain commodity information (for example, basic information such as a commodity code and a commodity name) of the commodity, then scan the barcode of the electronic price tag, obtain identification information of the electronic price tag, and transmit the commodity information of the commodity and the identification information of the electronic price tag to the server. The server can find out detailed information such as real-time price, production place, production date, quality guarantee period and the like of the commodity from the commodity information base according to the commodity information of the commodity, and generate display information of the commodity according to a pre-designed electronic price tag display frame. Optionally, the electronic price tag has a plurality of specifications, and different display frames can be designed according to the specification of the electronic price tag.
As described in the foregoing embodiment, the electronic price tag is periodically in an active state and a dormant state, when the electronic price tag is in a transient active state, a heartbeat data packet of the electronic price tag is broadcasted, when there are a plurality of base stations in an application scenario, the plurality of base stations may all receive the heartbeat data packet broadcasted by the electronic price tag, detect signal strengths between each base station and the electronic price tag, upload the heartbeat data packet of the electronic price tag and signal strength information of the electronic price tag to a server, and complete networking by the server.
In step S31, the server selects a base station satisfying the predetermined signal strength condition as a target base station, for example, the server may bind the base station with the strongest signal strength of the electronic price tag as the target base station and the electronic price tag, or may bind the electronic price tag with any base station with the signal strength of the electronic price tag reaching the predetermined signal strength as the target base station.
After networking is completed, the server sends display information corresponding to the commodity bound with the electronic price tag to a target base station bound with the electronic price tag, after the networking of the electronic price tag is completed, a display information acquisition request is sent to the target base station when the electronic price tag is in an active state, at the moment, the target base station replies a data transmission instruction and the display information of the commodity to the electronic price tag, after the electronic price tag receives the data transmission instruction, the electronic price tag continues to be in the active state and receives the display information of the commodity at the same time, and the electronic price tag enters a dormant state again until the display information of the commodity is received, and repeats a low-power-consumption working mode.
According to the data transmission method of the electronic price tag, when the usage amount of the electronic price tag is large, the electronic price tag actively requests the base station for commodity information of a corresponding commodity, the base station can receive a display information acquisition request sent by the electronic price tag almost every moment and transmit the display information of the corresponding commodity to the electronic price tag, the base station can transmit more display information of the commodity corresponding to the electronic price tag in unit time, and the efficiency of transmitting the display information to the electronic price tag is greatly improved.
