Embodiment 1

[0051] Such as image 3 As shown, Embodiment 1 of the present invention proposes a method for data transmission, based on the base station, the method includes the following steps:

[0052] Step S110: Receive the display data delivered by the server.

[0053] Specifically, the display information of the electronic price tag will be updated regularly or irregularly. At this time, it needs to request the base station to request the corresponding display data, and the update of the display data of the base station needs to be obtained from the server. When the server receives the The display data update request will send the corresponding display data to the base station, and at this time, the base station can receive the display data sent by the server.

[0054] Step S120: Compress the display data using a preset streaming compression algorithm, generate and store a corresponding display data compression package.

[0055] Specifically, when the base station receives the displa...

Embodiment 2

[0063] Such as Figure 5 As shown, Embodiment 2 of the present invention proposes a data transmission method based on the electronic price tag terminal. The method includes the following steps:

[0064] Step S210: sending a new display data request to the base station, and receiving the display data compression package sent by the base station when the display data request is passed.

[0065] Specifically, the display information of the electronic price tag will be updated regularly or irregularly. At this time, it needs to request the base station to request the corresponding display data, that is, send a new display data request to the base station, and when the display data request passes, receive The base station sends a compressed display data packet, which is a compressed display data packet obtained by compressing the display data with a preset streaming compression algorithm in Embodiment 1.

[0066] Step S220: Decompress the compressed display data package by using a...

Embodiment 3

[0074] Such as Figure 7 As shown, Embodiment 3 of the present invention proposes a terminal 20, the terminal 20 includes a memory 21, a processor 22, a program stored in the memory and operable on the processor, and a program for implementing the processor 21 and the memory 22 The data bus 23 for connection and communication between them, when the program is executed by the processor, implements the steps of the data transmission method in the first embodiment above, as described above in detail, and will not be repeated here.

[0075] It should be noted that the embodiment of the terminal 20 and the method embodiment 1 in the embodiment of the present invention belong to the same idea, and the specific implementation process is detailed in the method embodiment 1, and the technical features in the method embodiment 1 are the same as in the terminal 20 embodiment. Correspondingly applicable, no more details here.

Abstract

The embodiment of the invention discloses a data transmission method, a terminal and a storage medium, and belongs to the technical field of electronic price tags. When the method is based on a base station end, the method comprises the following steps: receiving display data issued by a server; and carrying out compression processing on the display data by adopting a preset streaming compression algorithm to generate a corresponding display data compression packet and storing the display data compression packet. When the method is based on an electronic price tag end, the method comprises the following steps: sending a new display data request to a base station, and when the display data request passes, receiving a display data package sent by the base station; performing decompression processing on the display data compression package by adopting a preset streaming decompression algorithm, outputting corresponding display data and displaying the display data on the current screen. According to the technical scheme, the technical problem that the transmission failure rate and time are increased due to the fact that the transmission data volume is too large when data transmission is carried out between an existing electronic price tag and a base station can be effectively solved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of electronic price tags, and in particular to a data transmission method, terminal and storage medium. Background technique [0002] Electronic price tag is an electronic display device with information sending and receiving function, which is mainly used in electronic labels for displaying price information in supermarkets, convenience stores, pharmacies, etc. When it is placed on the shelf, it can replace the traditional paper price tag. Each electronic price tag is connected to the computer database (base station) of the shopping mall through a wired or wireless network, and the latest commodity information is displayed on the screen on the electronic price tag. . It can be seen that the electronic price tag has actually successfully incorporated the shelf into the computer program, got rid of the situation of manually changing the price tag, and realized the price consistency ...
