Day letter each LED wireless information release system adopts advanced B/S structure mode, mainly contains the operation page, IE center service software, data center, terminal equipment, four parts. Function mainly from the program information, send, center service program automatically generated information playlists, and through the service center, sent to the corresponding packet terminal equipment by the machine control system in effective period in the center of the LED display according to the information generated playlist for broadcast.
The network architecture
        System development USES the advanced B/S mode of network architecture, service center all data storage and server to facilitate daily system maintenance, and provide convenient and simple parameters configuration function according to different network environment to realize fast installation deployment server system. Customer operation UI anywhere on any computer can access to the Internet connection center, data management, and other operations, even if the center address changes, the system configuration function can easily connect the new center address.
The system user permissions
         System adopts the way of user permissions corresponding screen group, fully satisfy different users to send information to the corresponding user screen group's requirements, each other, their relative independence, assigned by the system administrator agrees to management.
The system administrator has the highest authority by default, general based data management center system administrator. All the ministries users assigned by the headquarters unified center administrator login ID, the administrator can through the system to provide the way to select screen group easily assign each user corresponding all LED screen, and manage to send each own screen.
Real-time online monitoring equipment
All terminals are keep real-time online, through service program trunking communication link, the user can easily realize real-time monitoring on IE all screen set of wireless terminal equipment is normal work online, real-time and refresh the network registration time, automatic calculation length, provide effective basis for system managers evaluate equipment working status.
Wireless data transmission
        Using UDP subcontract parts of wireless data transmission system packet transport, its advantage lies in the data transmission speed, high efficiency and low packet loss rate. Specific process roughly divided into: first of all, by the ten packets by center each group package, every package labels, a set of package will lower their phones to record has lost package labels, center received lower machine return label will only resend again has lost package. So will the data sent in sequence, and the safety and efficiency of data transmission.
         The third party forward data in real time
Center service software can automatically grab the third party software database files, will need to send information in real time automatically according to the predefined formats issued to need to play in the LED display, and carried out in accordance with the predefined time play.
End-to-end solutions
        With each day letter LDE control system is used, provide end-to-end solution as a whole.
