Intelligent conference system is the process of meeting attendance, voting, and nations language translation, on-site camera video tracking function, and in the process of a speech management to human high-tech level, make the meeting may be a key control.
 
What is the central control system?
 

Refers to sound, light, electricity, etc. Various kinds of equipment for centralized control equipment.
 
Modern conference room is equipment?
 

Conference equipment: video (TV/plasma displays, projector/video stage, DVD/videocorder, camera ball) audio (CD/MD, amplifiers, mixers, microphone, mixer, etc.) data equipment (computer) and related equipment.
 

Environmental equipment: temperature/humidity regulator, lighting, electric projection screen, electric curtain, electric door, electric lift central control system, etc.
 

A microphone two horn can open a congress, this is how many years the traditional mode of extended meeting. And in human communication process, the effectiveness of information 55% dependent on visual effect, 38% depends on sound, only 7% depends on the content. So just use a voice to show, far cannot satisfy the requirements of modern meeting. Modern meeting requirements concise and lively expression participants thought, vivid and clear display their products. With professional words also expounds the content of the above is: high quality audio signal, high-resolution video moving, state pictures and images, physical material accurate data to express the thought of the participants.
 
Four subsystems
 

Four parts to realize function each are not identical, you can according to the actual need to choose what you need subsystem, the functions of each subsystem for further details
 
A, digital conference and simultaneous interpretation system
 

Digital conference network word technology first, make the superiority of digital technology to promote. Use simple network system processing and transmission of digital signal, not only greatly improve quality, but also simplify the installation and operation.
 

DC control system have two choices: one is the advanced operation scheme of software implementation of adjustment and control; Another kind is no maintenance member of the automatic control. Easy to operate is both common features. DCN on all types of meeting can provide flexible management, whether small informal meeting or multilingual, thousands of international conferences of all handy, operation freely. DCN is similar equipment take the lead in using full digital technology system. Has the multi-function, high quality, digital transmission security, reliability, etc. The whole network realization function is meeting to discuss speech, meeting the collective voting, meeting the real-time multilingual translation (up to 14 languages), the recording, all kinds of audio signal access, etc.
 

Function: to all participants transfer stability, pure conference audio signal, including meeting collective voting and realize real-time multilingual translation of simultaneous interpretation.
 

Features: DCN is similar equipment take the lead in using full digital technology system, has the multi-function, high quality, digital transmission security, reliability, etc. Functions: through the network can realize meeting to discuss speech, meeting the collective voting, meeting the real-time multilingual translation (up to 14 languages), full range recording, all kinds of audio signal access, etc.
 
Second, the projection display and sound system
 

A. projection display system
 

The projector from 3 guns projection CRT way to now LCD single gun LCD projection and the latest development of the DLP digital projector, although experienced only short for several years, but the technology invention but has brought people much convenience and benefits.
 

Taking the projection way to distinguish, there are cast, the DLP projection, combination splicing three ways. Is divided again for hoisting, sit put two kinds, its advantage is site high efficiency and easy installation. The DLP projection way resistance to ambient light interference ability, air, beautiful, defect is requirements area should have enough depth. Combination splicing is currently greatly surface projection the first selection of means, is widely used in television, traffic control monitoring center, alarm center, forces and so on, its advantage is high brightness, the pictures combination way is flexible, screen size is large, but also need to have enough investment.
 

B. sound system
 

Sound mainly includes power amplifier, the main speakers, the center channel speaker, surround speakers, positioning speaker components, functions can be divided into public address, sound, the sound, surround, different configuration and the different grades of audio equipment will build a completely different effect, therefore in the concrete configuration and be according to the requirements of the environment, and combining with actual need, through consulting professional audio people given a set of real practical, perfect sound system.
 

Three, multimedia peripheral equipment
 

Modern meeting need a variety of video signal and field environment control, if you want to play some product demo CD and video which requires DVD and video recorder, such as field environment regulation and control the dimming lamp, fluorescent lamp and electric curtains, etc. We put the above equipment collectively referred to as multimedia peripheral equipment. Here's a list of some modern meeting required some multimedia peripheral equipment: DVD video video stage tape holder TV computer projector electric screen scene lighting electric curtain electronic whiteboard...
 

Four, intelligent control system
 

Modern conference facility set a computer and a variety of audio input/output devices, the operator needs to realize control of each equipment, but also complete equipment room of signal switching, make in one or more studio broadcast equipment, at the same time modern meeting to light, electric screen and curtain cooperation control is also an indispensable requirement.
 

In view of the above question, central control system is the best solution, it will be a variety of signal output and the choice of specific equipment operating focus on a touch screen or computer control interface, the operator through the intuitive control interface will be complex conference equipment operation and environmental control become relaxed freely.
 

Modern session focused on the computer and a variety of audio input/output devices, the operator needs to realize control of each equipment, but also complete equipment room of signal switching, make in one or more studio broadcast equipment; At the same time modern meeting to light, electric screen and curtain such as environmental control is also an indispensable requirement. All sorts of function concentrates in together, simple to operate by hand, the operator will appear very tedious. How to turn red tape for simple? Give it to intelligent conference system! 

System characteristics
 

Modern session focused on the computer and a variety of audio input/output devices, the operator needs to realize control of each equipment, but also complete equipment room of signal switching, make in one or more studio broadcast equipment; At the same time modern meeting to light, electric screen and curtain such as environmental control is also an indispensable requirement. All sorts of function concentrates in together, simple to operate by hand, the operator will appear very tedious.
 

How to turn red tape for simple? Give it to intelligent conference system!
 

Data integration design, the conference room all the equipment of an organic unity together, thereby increasing the host for the whole conference control degree
 

2. LCD touch screen visualizations, visual interface make various equipment was accused of become simple and convenient
 

3 technology, intelligent integrated fully embodies the modern meeting in high grade
 

Homonyms of standardization, systematization meeting configuration can help enterprise image of the improvement of improve the efficiency
 

Intelligent meeting system and the traditional system of the relation and distinction between
 

Intelligent control with the traditional or conventional control have close relations, and are not mutually exclusive. Conventional control often included in the intelligent control of intelligent control are also using conventional control method to solve the control problem of "low", and tries to expand the conventional control method and establish a series of new theory and method to solve more challenging complex control problem.
 

Traditional data automatic control is based on the determined on the basis of the model, and intelligent control of the research object of the existing model serious uncertainty, namely model unknown or those little model structure and parameters in a large range fluctuation, such as industrial process of pathological structural problems, some interference can't forecast, cause cannot establish its model, these problems based on the model of traditional automatic control is difficult to solve.
 

This traditional automatic control system of input or output equipment and people and outside environment information exchange is not convenient, want to create a can accept block, graphics and even script and verbal command and other forms of information input device, can more deeply and flexible and exchange of information system, as well as expand output device ability, to be able to use text, drawings, three-dimensional image, language form output information. In addition, usually automatic device can't accept, analysis and perception various see and hear the voice of the image, the combination of external and other information. For expansion of information channel, it must give automatic device how to simulate all kinds of mechanical way feel accurate send sound device, namely text, voice, object identification device. The good news is that, in recent years the computer and the rapid development of multimedia technology, intelligent control in this hand development provides material to prepare, and makes intelligent control into a multi-dimensional "stereo" control system.
 

3 the traditional automatic control system for the requirement of control tasks or make output for fixed value (control system), or make output follow the expected trajectory (follow system), therefore has the characteristics of oneness control tasks, and intelligent control system of the controlling tasks can be more complex, for example, in intelligent robot system, it requires system for a complex task with automatic planning and decision-making ability, have automatic evades obstacles movement to a expected target location ability, etc. For these has a complex task requirements of the system, using intelligent control mode can meet.
 

4.Homonyms of traditional control theory of linear problems have a mature theory, but to highly nonlinear control object although there are some nonlinear method can use, but unsatisfactory. And intelligent control to solve this kind of complicated nonlinear problem to find a way out, to solve this kind of problem effective way. Industrial process intelligent control system is in addition to the above several characteristic, and other characteristics, such as controlled object often is dynamic, and control system online sports, general requirements have higher real-time response speed and so on, just is these characteristics and decided it with other intelligent control systems such as intelligent robot system, aerospace control system, transportation control system difference, decided to its control method and form unique.
 

⒌ and traditional automatic control system, compared with intelligent control system has enough about human control strategy, controlled object and environment of the relevant knowledge and the ability to use the knowledge
 

6.The automatic control system with traditional compared, intelligent control system to knowledge representation of the mathematical model and the generalized mathematical said hybrid control process, USES the open closed loop control and qualitative and quantitative control with modal control mode.
