An easy control-conference room control solution
An easy control-conference room control solution
1. The proposal of the central control plan With the continuous progress of science and technology, customers have put forward increasingly higher requirements for various multi-functional conference rooms, academic exchange centers, training centers, command centers, and monitoring centers; various advanced The audio and video equipment, electronic equipment, etc. are used by many high-demand customers in order to achieve the desired effect. However, with the increase in the number of devices, there will be more and more remote controllers and more and more control methods, and people are at a loss. At the same time, it is difficult to control the environment in a timely manner as needed to achieve the desired effect.
The fully automatic intelligent equipment central integrated control system can control almost all electrical equipment through the touch-type wired / wireless LCD display control screen. All electronic equipment in the hall can be controlled through a touch screen with video surveillance, including projectors, screen lifting, audio and video equipment, signal switching, as well as lighting, system dimming, volume adjustment, etc. in the venue. Simple and clear Chinese interface, just touch the corresponding interface on the touch screen with your hand, the system will automatically help you achieve the function you want to do, it can not only control DVD, video playback, fast forward, fast reverse, pause, select It has functions such as music, and can control the switch of the projector, the switching of signals, as well as the rise and fall of the screen, the adjustment of incandescent lamps, the switch of fluorescent lamps, etc., which eliminates the complicated and large number of remote controllers.
2. Overview of the central control plan
· Central control equipment is the soul of the system design, which integrates lighting, mechanical, projection and audio-visual control methods in one body, providing users with simple and direct control solutions, so that users can easily master the entire space environment Status and function.
The whole system is centered on the central controller. It is connected to each device with a control bus, accepts the control requirements issued by the operator, and then sends control commands to each extended control device and controlled device. All control functions are programmed by special system software, and specific control can be realized by color LCD touch screen or ordinary PC. The operation interface is intuitive and easy to understand (full Chinese, modularized graphics) and easy to operate according to the actual requirements of users.
Control effect:
â—‡ Can control the operation of various types of video and audio equipment according to needs (such as various function adjustments on the projector, such as brightness, contrast, computer / video screen conversion, video recorder function control, such as playback, fast forward, fast reverse, pause , Stop, recording, video recording and other functions and advanced settings such as device settings);
â—‡ According to the needs, through the control of various professional matrices and related equipment, it can complete the switching of various audio / visual / computer signals and adjust the signal path;
â—‡ Volume control box can be used to control the volume;
â—‡ The stepless dimming of the incandescent lamp in the conference center can be performed, and the fluorescent lamp group can also be switched on and off;
â—‡ Through the relay controller, complete the control of the electric curtains and electric screens, the switch of the electromagnetic lock and the control of the power-on single-transparent glass;
â—‡ The central control equipment can design programs according to different needs, such as various lighting modes, dimming rate, password protection use rights, etc., and adjust it on the spot according to the actual use. In addition, according to the specific needs of users, it is possible to write a linked operation program, and only one command can complete multiple actions.
The central control system equipment configured in this solution can realize the following control functions:
(1) Various function adjustments on the projector, such as brightness, contrast, computer / video screen conversion, machine on / off, etc .;
(2) Function control of VCR, DVD player, recording deck, such as playback, fast forward, rewind, pause, stop, recording, video recording, warehouse entry, warehouse exit, opening / closing, etc .;
(3) Volume control;
(4) A variety of video and computer signals can be switched to the projector at will;
(5) Grouped on / off control of fluorescent lamps (light pipes);
The control operations of all these devices are performed on the 5.7-inch SV wireless color LCD touch screen of the control system.
The SV touch screen can input the user's favorite colors, patterns, national texts and fonts, and can add user icons, pop-up sub-pages and preset functions. High-definition LCD touch screen display, you can customize various control buttons and graphics.
3. Hardware introduction of the central control solution
3. A new generation of main control machine SV-PRO
SV-PRO is not only a high-performance integrated control system, but also has extended functions. Its cutting-edge technology and superior and reliable performance make the SV series better than other control systems. SV-PRO provides communication that the existing control system did not have. The unique DPA (direct processor communication) of Xunkong is connected to the local area network or the Internet via Ethernet for remote debugging and control. The expansion slot of DPA card of SV system is suitable for 10M, 100M and future communication protocols like ATM and FIREWARE. Each SV system has an IP address specified by the user, fully integrated with your computer network.
The SV control system can be equipped with any fast control panel, touch screen, wireless transceiver, interface and network equipment. The fast control SV system uses unique advanced technology, as long as it is connected to the controlled equipment, you can build your own comprehensive control system.
The description of the host port of the SV-PRO control system is as follows:
