In addition to meeting the traditional simple meeting requirements, a command center should also have elegant style, beautiful sound quality, clear image demonstration, and can be equipped with large-screen display system, digital conference discussion voting system, camera tracking system, signal switching, Paperless conferences, central control systems, sound reinforcement systems, etc. Select advanced DVDs and cameras, as well as physical and teletext transmitters to restore their images through large screens. For more efficient and real-time command, you need to have a central integrated control device to control all audio and video equipment, signal switching, volume adjustment, etc. Features that greatly increase productivity and simplify complex operations, making it suitable for everyone without the need for expertise.
Based on the needs of this field and our practical engineering experience, we divided the entire conference system into the following subsystems.

(1) Display splicing system
(2) Central Control System
(3) Conference sound reinforcement system
(4) Conference speech, camera tracking system
(5) Paperless conference system
(6) Signal switching system
1, display, signal switching system
The size of the meeting varies from a few to a few dozen people. Therefore, according to the size of the command center, it is necessary to select the appropriate display terminal equipment to ensure that all participants can clearly see the content displayed in the meeting and achieve the desired effect of the meeting.
The conference display design uses 9 splicing screens and 1 splicing processor to form a display system. The splicing process can realize the functions of video multiplier, zoom, picture-in-picture, splicing, seamless switching, character overlay, etc. Display mode: picture-in-picture, picture-out, cross-screen display, window roaming. The processor adopts pure hardware architecture, plug-in design, no operating system, and can process all input signals in real time. All signals have exclusive bandwidth, ensuring no delay, no discretization, no frame loss, and realize images. The perfect presentation.
Signal source access adopts 72 input and 72 output HD hybrid matrix, can access 16 RJ45 input, 40 HDMI input, 4 DVI input, 16 DVI output, 16 HDMI output, computer signal can be connected through VGA interface The camera's video signal can be connected to the system through the DVI interface. When the access signal source reaches a large scale, the 72-in 72-out-mixing matrix can seamlessly switch the signal that needs to be seen to the spliced ​​display.
2, digital conference system design
The digital conference host DK-4100, with digital processing and transmission technology with independent intellectual property rights, revolutionizes the introduction of all-digital technology and integrated network technology into the conference system, fully integrating advanced digital technology, network technology and audio technology. Combined, the system has 5 strong voting and 5+1 simultaneous interpretation functions, such as check-in, voting, discussion, video tracking, etc., and can also be seamlessly connected with the intelligent central control system.
3, sound reinforcement system design
1. Sound source: It mainly includes digital conference speech unit, wireless microphone, DVD player multimedia computer and other sound source devices, which can play CD records, DVD audio and video images.
2, conference audio processing equipment: is the core equipment in the conference sound reinforcement, can carry out multi-channel audio signal mixing and amplification, switching, high and low sound adjustment, effect compensation control, volume adjustment, recording, playback;
3. Amplifier and speaker: The sound quality and sound field uniformity of the entire sound reinforcement system mainly depends on the quality and arrangement of the speakers. Different types of speakers need to be equipped with different power amplifiers.
4. Central control system design
The central control host DK-7800 adopts 1GHZ high-speed processor, built-in 2G capacity DDR2 memory and 8G large-capacity flash memory, which makes the system processing and access speed fast and stable, and also ensures the appropriate upgrade in the later stage. 9-way bidirectional programmable RS -2323/485 port, 8-channel infrared output control port, which is connected with each device by control bus. The color touch screen accepts the control requirements from the controller, and then sends control to each extended control device and controlled device through various control interfaces. Instructions, all control functions are programmed through dedicated system software, and specific control can be achieved through a color LCD touch screen.
The command center is equipped with a power management module, which is responsible for the power management of the equipment in the command center. It can control the power supply of the sound system, projector power, projection screen lift, desktop lift, curtains, etc. All the controls can be completed through the wireless touch screen. In the case, it can be controlled by hand. In addition, the central control system can control the DVD player, LCD TV, curtains, etc. through the infrared interface of the central control host.
 
 
 
 
After programming, a complete central control system will be formed, and the following control functions can be easily realized:
1, HD hybrid matrix dependent switching control
a) Provide video, VGA image and audio signal switching control functions to realize audio signals from satellite signals, cameras, teleconferencing systems, DVD, VGA signals, etc., and audio from mixers, computers, conference microphones, remote terminals, etc. The signal source is conveniently and quickly switched to the audio and video terminal output.
b) The touch screen can automatically and modularly control the HDMI and VGA signal switchers configured in the multimedia system. Users can conveniently and quickly control various complicated audio and video and computers by clicking the beautiful buttons on the color touch screen with humanization, clear classification and simpleness. Signal switching eliminates complicated manual switching, improves work efficiency, and reduces false switching.
c) Select any HDMI signal device to automatically switch the audio and video matrix and VGA signal to the corresponding input and output points. If the selected device contains video signals, the system automatically opens the projector, the screen automatically lowers, and the fully automatic humanized operation improves the work. Efficiency and streamlined operational steps. Each system linkage program can be programmed according to user requirements to meet different user needs.
2, projection display system control
a) The user can easily control the functions of the switch of the projection display system and signal switching through the color touch screen.
b) With flexible programming settings, a delay can be added during the projector's switching process to protect the projector.
3, audio, video conferencing system control
a) Compatible with the remote video conferencing system to realize the signal switching and display signal distribution status of the remote video conferencing system on the touch screen.
4, infrared device control
a) The user controls the functions of playing, stopping, pausing, and skipping the audio and video equipment of all available remote controllers such as DVD, CD, TV, VCR, etc. through the color touch screen, and can control the entire conference with a single finger. The rhythm makes the various meeting processes smoother, avoids harassment of participants, and greatly improves the efficiency of the meeting.
5, paperless conference system design
The paperless conference terminal system adopts the conference management platform with independent intellectual property rights of Yide YDIT, which can provide rich conference functions and assist the conference organizers to control the entire conference process efficiently and conveniently. Provides a variety of service functions for pre-conference preparation, in-meeting management, and post-conference archiving operations to ensure that meetings are conducted in a normal, orderly, and secure manner. The system is equipped with a conference application that supports common conference functions and integrates advanced conference functions to fully meet the needs of participants. Throughout the conference, the participants can provide excellent digital office and experience special effects such as sliding, dragging and zooming. All operations are completed through one terminal, which simplifies the use of paper documents and greatly advances the development and progress of paperless conferences.
