With urbanization, the number of outdoor advertising screens has surged. However, traditional wired networks are difficult and costly to lay in remote areas, and struggle to adapt to the changing locations of advertising screens. Traditional wireless networks are prone to signal attenuation and interruption outdoors, failing to ensure stable network connectivity and content updates for advertising screens. Therefore, an efficient wireless networking solution is urgently needed.
The industrial 4G router is specifically designed for industrial scenarios. It features industrial-grade protection, operating stably in temperatures ranging from -40℃ to +75℃, and is dustproof, splashproof, surge-resistant, and vibration-resistant. It is equipped with a high-performance processor, offers a rich array of interfaces, supports multiple carrier 4G networks, and is easy to deploy with a simple plug-and-play SIM card.
The ZR2000 series 4G wireless router has a built-in 4G communication module that connects to a base station to obtain network access. It encapsulates advertising screen data according to the TCP/IP protocol and transmits it to the internet via the 4G network. Simultaneously, it decapsulates data from the internet and forwards it to the advertising screen, enabling bidirectional communication between the advertising screen and a remote platform.
The outdoor advertising screen system architecture consists of a front-end advertising screen, a 4G industrial router, and a remote management platform. The advertising screen is responsible for content playback and environmental data collection; the industrial router connects the advertising screen to the internet; data is transmitted via 4G network with VPN encryption; the remote platform, based on a B/S architecture, enables functions such as equipment status monitoring, content publishing, and parameter adjustment.
The 4G wireless module breaks geographical limitations and allows for flexible deployment; industrial-grade quality ensures stable operation in harsh environments, guaranteeing advertising playback; remote centralized management reduces maintenance costs and improves management efficiency; excellent environmental adaptability extends equipment lifespan and reduces failures. Urban bus stop advertising screens use 4G industrial routers to achieve real-time content updates, reducing failure rates and maintenance costs; this solution can also be used for highway advertising screens to update advertisements and traffic information promptly.
