Author：admin / Publication time：2019-06-21

1 Application Overview:

At present, the telecommunications network management center applies a digital display splicing wall system to provide comprehensive management and high-definition large-scale display for multiple networks operated by telecommunications, making it a highly intelligent control system with easy operation. By utilizing the powerful display screen and window combination function of the digital wall splicing system, it can be applied to areas such as interactive networks, transmission networks, signaling networks, intelligent networks, etcGSMVarious real-time information such as digital maps, wireless network base station distribution maps, network element topology diagrams, real-time network performance status tables, real-time warning tables, and statistical analysis tables are aggregated and displayed on the same combination screen. Realize resource sharing between systems without affecting each other, enhance collaboration and communication, and further improve the unified management function of the network management center.

System composition: LCD large screen digital display splicing wall, multi screen processor, display wall application management system. Auxiliary system: Integrated video surveillance system
twoOverview of system functions:
1. VGASignal display
User non network computer signals(VGAThe signal is partially output to the splicing wall through VGA switching matrix (optional), and real-time display of single screen, multi screen, and full screen splicing is achieved on the splicing wall through the built-in image processor. Some signals can be output to the VGA input port of the multi screen processor, and can be displayed on the splicing wall for various operations such as cross screen display, full screen roaming, arbitrary scaling, stacking, etc., without being limited by physical splicing.
2.IPNetwork signal display
With multiple network connection functions, it can connect simultaneouslyUNIXIn networks and other data networks, workstations in the network can be displayed and accessed in various ways such as scaling, cross screen, stacking, etc. on a large screen through Ethernet via a multi screen processor. The computer signals of the UNIX platform in the telecommunications network management system are displayed using X-Window display mode using software such as VLink developed by Youse. The combination screen is used as a virtual screen for the UNIX system, and the graphical desktop of the Windows series network operating system can also be displayed in window form through VLink. Enable operators to control the combination screen on the network workstation.
3. Video information display (compatible with various standards PAL/NTSC/SECAM)
The various real-time monitoring video signals of telecommunications applications are processed through video matrix (optional) and partially output to the large screen. The integrated image processor is used to perform real-time display of single screen, multi screen, and full screen splicing on the large screen. Part of the signal is connected to a multi screen processor to achieve real-time display of any path or multiple video signals on the combined screen at any size and position.

4. Multiple mixed signal display methods:

realizationRGBThe signal, network signal, and video signal are mixed and displayed on the large screen simultaneously.
