Command Center Conference System Solution

Command Center Conference System-Scheme Construction

System Overview:
The command center is a place for consultation and command during the handling of public incidents. It has the function of holding a video conference, which is convenient for leaders to listen to the situation report and expert consultation suggestions, and conduct remote command. With image access function, it is convenient for leaders to understand the scene. When an event occurs, the application system can be called to carry out prediction and early warning, scheme discussion, etc., to provide decision support for leaders.


Demand analysis:
Multi-party call function: The command center conference system needs to support multi-party calls and can accommodate multiple conference members to participate in the conference at the same time to ensure smooth and real-time communication.
High sound quality effect: In order to ensure the clear voice communication between the conference members, the conference system needs to provide high-quality audio function, reduce the interference of background noise, and ensure that the participants can clearly hear each other's speech content.
Screen sharing and document sharing functions: In order to facilitate information sharing and discussion among conference members, the command center conference system needs to support screen sharing and document sharing functions. In this way, meeting members can share their own screen content and related documents, improving the efficiency of the meeting and the depth of discussion.
Audio and video recording function: for subsequent meeting playback and data arrangement, the conference system of the command center shall have audio and video recording function. In this way, the content and discussion of the meeting can be recorded and can be played back and referenced when needed.
Security and reliability: The command center conference system needs to have a high level of security protection mechanism to ensure that the content and information of the meeting will not be illegally obtained and leaked. In addition, the system should have reliable performance and stability to ensure that there will be no failure of important functions or stuck during the meeting.
Flexible scalability: Considering the particularity of the command center, the conference system should have flexible scalability. According to actual needs, the scale of the conference and the number of connected devices of the system can be expanded to adapt to conference activities of different scales and needs.


Design ideas:
According to the speech requirements of the venue, a U-section one-to-two wireless conference microphone is configured to facilitate mobile speech and venue interaction.
A set of hand-in-hand, 1 chairman microphone, 12 representative microphones, the chairman has a priority function.
Design with reference to Class I of National Auditorium and Conference Sound Amplifier Design Standard;
According to the sound line analysis and the coverage characteristics of each speaker, the layout of the sound reinforcement speaker in the command center is determined as follows by computer simulation operations:
• Design 2 main speakers, speakers installed in the front of the venue on both sides.
2 auxiliary speakers are designed, and the speakers are installed on both sides of the rear side of the venue.

• Power amplifier power in strict accordance with the speaker power 1.5~2 times configuration.
• 1 mixer, 1 audio processor (providing interface for audio, processing timbre effect), 1 feedback suppressor.
3.3.3 Distributed audio and video management system
Through the distributed audio and video management system, visual operation management is carried out for all node signals; the control of projection, TV, DVD and other equipment is operated. The design of this meeting is as follows:
A distributed management host, audio and video signals support real-time feedback, status synchronization, signal can be previewed and echoing;
• A wireless touch screen, touch control screen is a device for "communication docking" between people and the system;
• 6 sets of KVM-4K input terminals to convert the input audio and video signals into network signals, and to convert the control signals in the network signals into control signals;
• 6 sets of KVM-4K output terminals to convert network signals into audio and video output and display signals required by equipment, such as DVI signals, HDMI signals, audio signals and other audio and video signals;
• 6 sets of 4K input terminals, intelligent bandwidth rate tuning technology, audio and video can be synchronized, can be asynchronous switching;
• 6 sets of 4K output terminals, intelligent bandwidth rate tuning technology, audio and video can be synchronized, can be asynchronous switching;
A set of software, interactive signal transmission switching and equipment control signals are controlled in real time after logic operation by interactive interactive system;


Functional advantages:




Application effect:
• By configuring the conference speech system, the convenience of the digital microphone is higher, the function is better, and the sound reduction is higher when the number of people is larger.
-The speaker's voice is amplified with high fidelity and clarity through the sound system to meet the standards and requirements of the sound pressure level of the conference room;
Multiple regional operation centers can be deployed at the same time, allowing enterprise users to access nearby with the shortest path, improving the efficiency of multimedia communication such as audio, video, and data, and reducing data latency. In addition, the use of distributed deployment architecture can also bring an incidental value, that is, improve the stability of network video conferencing. Based on the distributed system architecture, the use of load balancing, multi-machine hot standby, fault redundancy design and other mechanisms to eliminate single point of failure, when individual servers or distributed deployment of regional operations center failure, users can be automatically transferred to other servers or operations center.
