　XUNWEI engineers: a standard multi-media classrooms, it should at least include computer systems, projection display systems, audio-visual systems, environmental equipment and systems, such as centralized control.
Computer systems that can direct a computer teaching, training and demonstrations can also be produced through a variety of software to different disciplines of teaching and learning materials. Computer systems can use the desktop and notebook computers can be used.
Projection display system consists of multi-media projector, Video Showcase, projection screen and so on. At present, the projector to see more brands. Import brands such as Japan, EPSON, SONY, and the Netherlands, PHILIPS, South Korea's LG products such as fully mature technology, reliable quality assurance, which is in the high-end models. China-made brands such as Digital China's Morningstar series projector is a low-end model, with its low price to occupy a certain market. Funding schools according to their own situation, the actual use of the environment to select the projector practical. In general, the choice of the physical resolution of 800 * 600, brightness in projector 2000ANSI about to meet the needs of our teaching.
Video Showcase ----- the choice of teaching without chalk, you can vote in kind, but also for film, a combination of slide projector, film projector function, an increase of teaching visual effects. Brands such as Samsung, Yuan-tai, Japan, JVC, Panasonic, XUNWEI booth and so on, bottom lights, side lights, flip-chip functions with positive and negative, in the 470 line-definition video about the use of different environments to meet
. From the texture on the projection screen can be divided into玻珠screen, white plastic screen, metal screen and so on. Classroom use is the way to vote, the general choice of white plastic screen projector more in line with the principle of optical reflection, the image cast a clear, bright, and affordable.
Audio-visual systems, including audio and video playback devices such as DVD, VCR, deck; line audio equipment if there is a microphone, wireless microphone; sound reinforcement equipment, amplifiers, speakers and so on. Some schools also have additional equipment such as mixer mixer, reverberation, etc., which were based on the size of the classroom, the walls of the absorption coefficient to determine the actual situation.
Environmental equipment mainly refers to adjustable lighting, electric curtains, so as to ensure good teaching and learning environment. How to effectively use and manage such a large number of multimedia devices, and not because of the switching equipment, the environment so that teachers deal of control, so that teachers and students dedicate to teaching and learning, the best solution is to have a central control system.
Centralized control system that combines computer technology, network technology up-to-date results, the operation of all equipment will be focused on the completion of an interface table. Its greatest feature is to allow the operation of complex process of simplification, so that users using a variety of equipment in the course of a relaxed, calm. Through years of development and use of the concept of centralized control has been widely accepted. The first to enter China's multi-media control system CRESTRON the United States and the AMX. More mature products, the system has good stability, but there are also a number of shortcomings: Installation trouble programming to be professionals at the scene, which to the future upgrade and maintenance is extremely difficult; controlled mechanical interface, once installed, can no longer change; expensive for most schools is concerned, can not afford such costs, from the point of view of cost performance, not the best choice. Some businesses to get involved since 1997 in this area. Learn through the years, absorbing and improving, there are several manufacturers have come to the fore, such as Beijing, WISE, Chengdu XUNWEI series control system, in terms of system stability, the function of the system, the system is scalable, can be replaced by even more than the import brands.
In the choice of control system should pay attention to the following aspects:
First of all, the system should be stable and reliable. The purpose of the installation of control systems in order to simplify the operation, so that teachers can easily control a variety of equipment, highly effective, if the system can not be unstable not only simplify the operation, it will affect the effectiveness of teachers. Choice is in the first place should be the quality rather than price.
Second, the system should pay attention to the openness and compatibility. Installation is simple, easy to upgrade, add, replace equipment that does not trouble; control interface simple and crisp, clear logic, easy to operate, fast.
Finally should be noted that the way to have a variety of control operations. Most have a touch screen control system, software, manual control panel and handheld remote control. School teachers the level of computer operation is inconsistent, and some teachers who are not good at computer, you can use the manual control panel. With remote control, a teacher from the rostrum, the same ease of control can be a variety of devices.
To sum up, to establish a comprehensive multi-media classroom, it should relate to sound, light, electricity and other aspects, the teacher should give full consideration to the question of the use of the process, on the one hand it is necessary to take into account the financial situation of the school; another On the one hand, teachers have to take into account the actual operation, simple, fast, convenient and to make use of the computer teachers are not very familiar with the courage to use in teaching multi-media equipment, and improve efficiency in the use of highly effective.
