Intelligent network control industry is due to the formation of AV system IPdevelopment of fusion, the control system also gradually towards thedevelopment of the network. Over the past few years is the peak period of AV industry development, along with the network popularization, now a single PC areconnected to Internet, everyone has the opportunity to contact network, the network is becoming a standard, suppliers, products, network cabling, detectionof many, but have been standardized, users generally accepted on the network.Although the standard in traditional AV system are not unified, but now the AVnetworks are using the IP standard, with IP fusion. AV on the market a number ofaudio and video products is on the network path, such as projector has thenetwork function. The AV system has the network function, but also promoted thenetworked control system, the control system of AV network control system,remote access.
Now the AV products have to integrate with IP, control for AV system services, so the control not only to follow the development of the AV system to go, controlproduct is more advanced with IP fusion. Control system now is one of 5 lines to achieve the transmission of audio, video and control, transmission, distribution,signal switching system are completed by the Super 5 lines. Its meaning is: the wiring is very easy, a line on the line; integrated easily; innovation of the AV system concept, put all the blend system A, V separated from the past together,forming a very simple, easy to use, maintenance system. This point in the controlhas been beyond the control function of the traditional system, into the field, the AV as a system to integrate, control.
Modern multimedia audio and video equipment and technology to bring forth the new through the old, electronic conference system is a set of standard oftenincludes a display (projectors, plasma screen, liquid crystal display), sound(speakers, amplifier, mixer), signal source (DVD, VCR, real booth), video conference and simultaneous interpretation system and so on. Because thesystem a lot of equipment, the use of different control ways, often require theoperation and management system of professional, appear in the control systemis for the user to solve the above problem.
With the teaching and distance teaching large conference center, continue to build multimedia exhibition hall and various institutions, even intelligent Home Furnishing market also is in warm up ceaselessly, control system operatedindependently tradition in management is still insufficient, the networkcommunication in the control system based on IP also emerge as the times require. Network control through the IP network to each sub system interaction,the system administrator can focus on each piece of equipment for hundreds of thousands of sets in the system for monitoring; in the long-distance teachingsystem in Beijing, the classroom teacher, also can operate in Sichuan,Guangdong Branch, camera and video and audio system, realize the network erabrings convenience for human life.
At present, the integrated control system is no longer a simple remote control function, but becomes a more humane, intelligent features. It is reported, the application in the control system in the domestic market may not be ten years, itsdevelopment to today, has been far beyond the simple collection of multi-channelremote control function. Intelligent control is centralized control progress to comprehensive management of large scale network system of sound, light, single environment of electrical equipment, automation control status status report of remote control and the tip. Now through the program and network communication, the control system can real-time reporting system; automaticweather forecast in advance, close the window and control air conditioning system; with the movement and brightness sensor, automatic light switches andadjust the brightness; the user only needs to hold the wireless touch screen, cansimultaneously control and surf the Internet on various equipment.
In the control system network in two aspects, one is the networking: controlsystems of the past is the single equipment, for example, has 10 rooms, each room a control system, of the. The first highlight the characteristics of present management function is the mutual control, can not control equipment is notmanagement, to manage all the equipment must be able to control every device,control function is not specific control equipment, but to control the control device, the control is not to control each room projector, screen and other equipment, but each room controller control, the equivalent of two level control,this is the upgrade to the concept of device management.
Only the network can achieve mutual control. Two: in the field of management,control product only control function in the past, and now in the control to understand the controller and equipment controlled equipment needs from themanagement of the state, if the equipment is in what state, if there is a fault,control systems need to understand these, and this had to a remote controlcommand requires equipment on or off, channel switching, and management functions required to understand AV equipment in what state, whether the failure? In the past one-way control step, has now become a two-way communication, the equipment state monitoring. There is also a management function is through this feedback into a time schedule task list, can setpermissions, the equipment management platform for setting and control of the whole system. For the management of different status of each equipment.
