【 Weak current college 】 building multimedia classroom---Power By 【 China power house network 】

A standard multimedia classroom, it should at least include computer systems, projection display systems, audio systems, environmental equipment and centralized control, and several other systems. Computer system that can directly be computer teaching, training and presentations by various software to make the teaching of different disciplines. The computer system you can use the desktop, you can also use the laptop. Projection display system consists of a multimedia projector, video display, projection screen, etc. At present, to see more of projector brand. Imported brands like the EPSON, SONY Japan and the Netherlands, Korea LG PHILIPS etc product grade complete, mature technology, reliable quality guarantee, in the case of high-end models. Domestic brands such as digital company Morningstar, Honghe Hite-Pro Series projectors, a low-end model, with its cheap price takes up a certain market. Schools can according to their own financial situation, the actual use of the environment to select practical projector. In General, select the physical resolution 800 * 600, brightness in about projector 810ANSI to meet the needs of our teaching. Video showcase-no chalk teaching select, you can vote for real, and cast film, slide projector, film projector functionality, increased teaching Visual effects. Brands such as Korea Samsung, Tiger, JVC, Matsushita, Japan Honghe booth, etc., a bottom lights, side lights, flip chip with positive and negative features, video clarity around in 470 line can meet the needs of different environments. Projection screen from the texture can be divided into glass bead curtain, white plastic curtain, metal curtain, etc. Classroom use is cast, select white plastic curtain generally correspond projector reflection, cast image clear, bright, and affordable. Audio and video systems including audio and video playback devices such as DVD, VCR, deck; audio device such as a wired microphone, wireless microphone, sound amplifying equipment power amplifier, speakers, etc. Some schools also have a tuning device such as a mixer, reverb, etc, which is based on the size of the classroom, walls of sound absorption coefficient of the actual situation. Environment equipment mainly refers to the adjustable lighting, electric curtains, etc., in order to ensure good teaching environment. How to effectively use and management of so many multimedia device, and not because the device switch, environmental control enables the teacher pulled to equip teachers and students to dedicate to the teaching and learning, the best solution is to have a central control system. A centralized control system is combined with computer technology, network technology, the latest results, put all equipment operating in one interface up to complete. It's best feature is to make complex and cumbersome procedures simplified, so that users in the use of various device easily and comfortably. Through years of development and use, centralized control concept has been widely been accepted. The earliest entry into China's multimedia control system is the United States of CRESTRON and AMX (Crestron). The product is more mature, system stability, but also has some shortcomings: installation troubles, professional on-site programming, this also to future upgrades and maintenance has brought about tremendous difficulties; control interface shall be installed, dull and never change; is expensive, for most schools, cannot afford such costs from the price-performance point of view, is not the best choice. Some businesses from 1997 to set foot in this area. Through years of experience, absorption and improve, several manufacturers have come to the fore, as Beijing's WISE, Guangzhou macro-control series control system, whether from the system's stability, system functionality, scalability, can be replaced even over imported brands. In the select a control system should note the following aspects
First of all, the system is stable and reliable. The purpose of installing the control system in order to simplify operations, allowing teachers to easily control various devices, to achieve a multiplier effect, if the system is unstable, not only does simplify operations, but will affect teacher teaching. So the choice is the quality in the first place instead of the price.
Secondly, it is necessary to pay attention to system openness and compatibility. Installation is simple, easy to upgrade, add or replace the equipment is not in trouble; the control interface is simple and direct, logical, clear, easy and fast. Finally it should be noted that to have a variety of control actions. At present most of the control system has a touch screen, software, manual control panel and a handheld remote control. School teacher of computer operation level is inconsistent, some teachers on computer operation is not cooked, you can use the manual control panel. With remote control, the teacher leaves the podium, similarly you can easily control various devices. To sum up, it is necessary to establish a complete multimedia classroom, it should relate to a sound, light, electricity and so on, should take full account of the teacher in question, on the one hand, it is necessary to take into account the financial situation of the school; on the other hand, the teacher of operational, simple, quick and easy to use on your computer is not very familiar with the teacher in teaching to use multimedia device, increasing efficiency, to achieve a multiplier effect.
