An electronic advertising terminal and system based on 4G communication network

Abstract

The invention relates to the field of embedded communication and advertisement, and proposes an electronic advertisement terminal based on a 4G communication network, including: an advertisement screen: used to display and play advertisement content; a control module: used to control the 4G access module and the advertisement center server The establishment and maintenance of the wireless communication connection between them, as well as downloading the corresponding configuration files and the advertisement files to be played to the advertisement center server, is also used to control the broadcast content of the advertisement screen, and can monitor the running status of the advertisement terminal in real time, respond Query requests and commands from the advertising center server; storage module: used to store advertisement files and configuration file information to be played; 4G access module: used to receive standard AT commands sent by the control module, and complete and communicate with the operator according to the AT commands The network establishes a network connection and communicates with the advertising center server through the operator's base station and network. The invention is convenient for management and maintenance, and can be widely used in the field of intelligent electronic advertisement.

Description

technical field [0001] The invention relates to the field of embedded communication and advertisement, in particular to an electronic advertisement terminal and system based on a 4G communication network. Background technique [0002] With the development of large-scale integrated circuits and the continuous improvement of manufacturing technology, more and more electronic advertising screens are pouring into daily life, such as subway advertising screens, elevator advertising screens, bus advertising screens, building advertising screens, etc. These are collectively referred to as electronic advertising. Electronic advertising is characterized by using electronic screens to present colorful advertising content, and using various advanced computer software to design advertising content, so that the production of advertising content is more refined, the content is richer, the color is softer, and the effect is more prominent. Compared with traditional print advertisements, e...

AI Technical Summary

Problems solved by technology

[0004] 1. The network compatibility is poor. As a dedicated low-speed network, ZigBee network needs to pre-set network parameters such as PANID, channel number, and network number during debugging, and the zigbee modules of different manufacturers are also incompatible. In order to realize the above solution, it is necessary to ZigBee modules in the entire network are required to use the same model of ZigBee modules from the same manufacturer

[0005] 2. The development and maintenance costs are high, and it is necessary to develop ZigBee base stations, electronic advertising terminals and the entire complete private communication protocol

In addition, maintenance personnel need to access the ZigBee private network to perform control, which is not conducive to remote maintenance

[0006] 3. Poor mobility, unable to perform real-time control and monitoring of mobile electronic advertising terminals (such as vehicle electronic advertising screens)

And the ZigBee protocol itself does not support mobility management
