Overview
What is a central control system?
      Refers to the sound, light, electricity and other equipment for centralized control of equipment.
      Modern conference rooms will generally have equipment?
      Conference equipment: video (TV / plasma display, projector / video display, DVD / video camera, video camera)
      Audio (CD / MD, Amplifier, Mixer, Microphone, Mixer, etc.)
      Data equipment (computer) and other related equipment.
      Environmental equipment: temperature / humidity regulator, lighting, electric projection screen, electric curtains, electric doors, electric lift central control system.
      A microphone two speakers can open a General Assembly, which is for many years has been the use of traditional conference mode. In human communication, the effectiveness of information 55% depends on the visual effects, 38% depends on the sound, only 7% depends on the content. So just use a voice to show, far can not meet the requirements of modern conferences. Modern meeting requirements of simple and lively expression of the participants ideas, vivid and clear display of their products. With the words of the same professional description of the above content is: high-quality audio signals, high-definition video, dynamic images and images, documents accurate data to express the ideas of the participants.

Projection display and sound system
      A. Projection display system
Projectors from the CRT three-gun projection to the present LCD single-gun LCD projection and the latest development of the DLP digital projector, although only a short period of a few years, but the technology has brought to the invention of too much Convenient and affordable.
      To distinguish between the projection, there are positive vote, rear projection, combined stitching in three ways. Front cast is divided into lifting, sitting two, the advantage of high utilization of the site, the installation is simple. Rear-projection method anti-environmental light interference ability, style, beauty, the disadvantage is that places require a sufficient depth. Combination splicing is currently the first choice for large-format projection, widely used in television stations, traffic control center, alarm center, troops and other occasions, its advantages are high brightness, flexible combination of screen, screen size, but also need to have sufficient investment .
      B. Sound system
The sound system mainly consists of power amplifier, main speaker, center speaker, surround sound speaker, positioning speaker and so on. The function can be divided into amplification, sound, live sound, surround, different configuration and different grades of audio equipment will create completely different Effect, so the specific configuration must be based on the requirements of the site environment, combined with the actual needs, through the advice of professional audio people are given a set of truly practical, perfect sound system.
      Multimedia peripherals
      Modern conference requires a variety of video signals and on-site environmental control, such as to play some of the product demo discs, video tapes which need DVD and VCR, such as the required environmental control dimming lights, fluorescent and electric curtains. We collectively refer to these devices as multimedia peripherals. The following list of some of the modern meeting of the necessary multimedia peripherals: DVD video recorder video cassette tape deck computer computer projector electric screen scene lighting electronic curtains whiteboard ... ...
Intelligent central control system
      The modern conference venue combines computers and a variety of audio and video input and output devices. Operators need to control each device and switch between devices to broadcast in one or more studio devices while modernizing Of the meeting on the lighting, electric screens and curtains with the control is also essential.
      In view of the above problems, the central control system is the best solution, it will be a variety of signal output and select the specific device operation concentrated in a touch screen or computer control interface, the operator through the intuitive control interface operation, the complex conference equipment Operation and environmental control becomes easy.
      Modern conference focused on the computer and a variety of audio and video input and output devices, the operator need to control each device, but also complete the signal switch between devices, so that broadcast equipment in one or more broadcast; Lighting, electric screens and curtains and other environmental control is also an essential requirement. A variety of functions together, simply by hand to operate, the operator will seem extremely complicated. How complicated for the simple? Give it to the intelligent conferencing system!

Intelligent conference system and the traditional system of contact and difference
      Conventional control is often included in the intelligent control, intelligent control is also the use of conventional control methods to solve the "low-level" control problems, trying to expand the conventional control (such as the use of conventional control, Methods and establish a series of new theories and methods to solve the more complex control problems.
      1. Traditional automatic control is based on the established model based on the intelligent control of the research object there is a model of serious uncertainty, that model is unknown or very little understanding of the model structure and parameters in a wide range of changes , Such as the pathological structure of industrial processes, some of the interference can not be predicted, resulting in the failure to build its model, these problems based on the model of traditional automatic control is difficult to solve.
      2. Traditional automatic control system input or output devices and people and the external environment is very convenient for the exchange of information, hope to create a print, graphics and even handwritten and verbal commands and other forms of information input device, can be more in-depth and flexible And system information exchange, but also to expand the capacity of the output device can be text, drawings, three-dimensional image, language and other forms of output information.In addition, the usual automatic device can not accept, analyze and perceive a variety of visible, Sound, sound, and the like, etc. In order to expand the information channel, it is necessary to provide an automatic device which can accurately simulate various senses in a mechanical manner, namely a character, voice, and object recognition device. Is that in recent years, the rapid development of computer and multimedia technology, intelligent control in this area provides the material preparation, intelligent control into a multi-directional "three-dimensional" control system.
      3. The traditional automatic control system to control the task request either to make the output value for the fixed value (adjusts the system), either causes the output volume to follow the desired movement track (following system), therefore has the control duty singleness characteristic, but the intelligent control system Such as intelligent robotic systems, it requires the system to a complex task with the ability of automatic planning and decision-making, there are obstacles to avoid the movement of an obstacle to the desired target position, etc. For these complex Of the task requirements of the system, the use of intelligent control methods can be met.
      4. The traditional control theory has a mature theory for the linear problem, while the highly nonlinear control object has some non-linear methods, but it is unsatisfactory.While the intelligent control to solve this kind of complex nonlinear problems found A way out, as an effective way to solve such problems.Industrial process intelligent control system in addition to the above-mentioned characteristics, there are other features, such as the controlled object is often dynamic, and control system online movement, the general requirements Have a higher real-time response speed, it is precisely these features and it is decided with other intelligent control systems such as intelligent robot systems, aerospace control systems, transportation control systems, etc., determines its control methods and forms of unique .
      5. Compared with the traditional automatic control system, the intelligent control system has enough knowledge about the human control strategy, the controlled object and the environment and the ability to use this knowledge
      6. Compared with the traditional automatic control system, the intelligent control system can adopt the non-mathematical generalized model of knowledge representation and the mixed control process expressed in mathematics, and adopt the multimode control mode combining open-closed-loop control and qualitative and quantitative control.
