With the deepening promotion of the concept of smart city, the application of various display smart terminal devices that accompany smart city is becoming more and more widespread, and the need for the unified management, information dissemination and reduction of operating costs of many smart terminals is increasingly urgent. In view of this requirement, after in-depth discussion with software system manufacturers, a set of solutions for managing many intelligent display terminals has been put forward. The application of this solution solves the problem well for many customers with centralized management needs. This management model can not only timely put advertisements and TV news (such as emergency announcements) on any one or more of the display screens. Real-time weather conditions, safety notifications, and monitoring cameras will be installed on the screen, allowing timely dissemination of safety information, traffic conditions, emergencies and so on, such as robbery of vehicles, license plate number, suspect information can be quickly displayed on the screen.
The control principle is as follows
Compared with synchronization system, cluster management and control system has the following advantages:
Terminal and server are developed based on Linux system, which is safe, stable and reliable. Multimedia files are transmitted through the network, centralized management is unified, real-time management and monitoring of terminal is realized, and fault alarm is timely upgraded. It has strong expansibility to meet the customization requirements, and can be docked with queuing call, exchange rate, stock market quotations, short message interactive games and other systems in the future. Various screen splitting and terminal grouping can be selected to play different contents instead of channels.
1. Real-time release of information
Real-time release of emergency information (typhoon warning), emergencies, television content, weather forecast, sports events, policies and regulations, bank foreign exchange, flights, on-site promotional information and other real-time information.
2. Network centralized management
The program content is transmitted through the network, and the remote control of the timing switch is realized without manual card exchange and card insertion. It does not need to consume a lot of manpower and material resources to solve the big management problems: often missed and misplaced, causing a large number of complaints from customers.
3. Content Screen Display
A screen can simultaneously play video (sketches, humorous movies), pictures, time, weather, news, scrolling subtitles, enterprises and other groups of information. To solve the problem of content attention, the audience can always get what they need from the screen.
4. Packet Playing of Content
Different platforms and waiting halls can play different program contents, different windows of the same platform and waiting hall can play different program contents, different time periods can play different program contents (divided into golden time and Non-Golden time). This makes the content of the program more targeted, and greatly improves the attention of the advertisement.
5. Information Security Guarantee
Servers and terminals adopt the most stable and reliable operating system. In the terminal aspect, the special encryption technology can control all non-platform audited and approved programs to play on the terminal (even if the network is disconnected, the program can not be replaced), which effectively ensures the security of outdoor media advertising. Program content adopts two-level auditing mechanism, which can effectively control the safe release of information content.
