The project is for a command center comprehensive building, divided into four regions, including the duty room(10 meters long, 10 meters wide, 3.5 meters high) in the first floor, the command center (15 meters long, 12 meters wide, 4 meters high) on the second floor, the conference room (12 meters long and 9 meters wide, 3.5 meters high) and leader’s office (5 meters long, 6 meters wide, 3 meters high) in the third floor. All audio and video signals on the third floor are required to be mutually controlled and seamlessly switched, and in the leader’s office it is also convenient to watch and control the audio and video signals in each area.
The aim is to design and build a command center for intelligent information communication. Adopt Xunkong distribution and control signal transmission technology, establish an efficient and practical real-time command system, realize the intercommunication and sharing of audio and video signals in multiple regions, and achieve the goal of unified and centralized management control of multiple signals.
1. Overview of distributed system
With the rapid rise in the current high-definition video technology and network technology, distributed system is much nore applied in the industry. In order to adapt to modern intelligent conference room, the distributed system(D3050) developed by Xunkong independently is recommended. The system is based on the network, integrated with the leading industry of the audio and video codec signal transmission and seamless switching, intelligent control technology, KVM switch transmission technology, high-definition image processing technology and digital network communication technology. It can conveniently connect the audio and video signals, control signals and computer KVM signals in all areas of the network to the system flexibly, and it is more convenient and efficient than the traditional engineering wiring and after-sales maintenance.

4. Solution of Display system for different floors
4.1 The duty room in the first floor needs five 65-inch LCD TV as the main display screens, which can display video signals from each floor and area in real time. The system topology diagram is as follows:
4.2 The command center on the second floor needs twenty 46-inch 3.5 mm high-definition LCD display unit (D5001), each seat with two LCD screens, one for a local computer screen and the other for external distributed signal access. The system topology diagram is as follows:
4.3 The conference room on the third floor is equipped with four 55-inch 3.5mm HD LCD splicing screen (D5002) for the main display, and two 70-inch LCD TVs for the auxiliary display. The system topology diagram is as follows:
4.4 The leader’s office is intended to use a 70-inch LCD TV as the main display as well as real-time display of video signals from various regions. The system topology diagram is as follows:
5. Visualized signal management platform for distributed system
This system is web-based and integrated with the leading A/V signal CODEC transmission and seamless switch techniques, intelligent control communication technique, KVM switch and transmission technique, HD image processing technique as well as digital net communication technique so that all the A/V signals in different areas in the network, control signal and computer KVM signal can be flexibly connected to the system. Supporting preview for input source signal image, window enlargement preview, virtual screen function, it also can monitor the signal image on each screen in real time and switch the signal seamlessly.
6. Connection Diagram for Audio and video signal of System
Command center and conference amplification system are both based on the national standard of sound amplification hall Level 1. We adopt professional array speaker (D2022) distributed in the room with wall-mounted installation. The array loudspeaker is good-looking with sound field covered uniformly, meeting the requirement that sound pressure level can bring amplification effect to all the command center. With a camera automatic tracking function, we use the high brightness of OLED display timing microphone, the conference HD1080 high-definition cameras can track the speakers in real time, convenient for a linkage meeting with all the four regions involved.
7. Switching diagram for KVM signal of System
Facilitate the administrative staffs of each floor to take over control of the regional computer.
8. Schematic diagram of system central control
Wireless touch screen can be used to centralize the management and control of equipment and signals in various regions, including large-screen image display, equipment switch, volume adjustment, light control, KVM takeover control and other control and adjustment.The system also supports arbitrary extension of the distributed codec terminal for future maintenance and upgrading.
The distributed system will create an advanced intelligent, efficient and stable signal comprehensive management platform for users.
