With the gradual popularization of modern education methods, many schools have implemented various programs to ensure the smooth progress of multimedia-assisted teaching. In order to enable schools with relatively weak economies to "arm" their classrooms and realize the modernization of education at an early date, we have designed a set of economic configuration plans to transform ordinary classrooms into projection multimedia classrooms. The construction of ordinary projection classrooms is based on the principles of practicality, sufficient use, ease of use and economy. Therefore, the following equipment is mainly selected: projectors, video booths, multimedia computers, central control systems, active speakers and screens.
[Classroom environment]
The projection classroom has an area of ​​more than 60 square meters and 45 sets of student desks.

7. UPS power protection device: APC BE525ICH, about 360 yuan
8. Multimedia teaching desk: Xinghua DMT-Z1 type, about 30 million yuan
[Construction Instructions]
1. Install projection equipment. Install a 120-inch projection screen on the left side of the blackboard near the window. Combined with the lens position and screen of the projector, one projector is suspended to form an independent projection system.
2. Customized console (teacher podium). The console integrates teaching equipment such as computers, UPS, video booths, and central control systems.

3. Install the sound system. The two speakers are hoisted on the walls on both sides of the blackboard in the classroom, and the power supply and other equipment are integrated in the cabinet.
[Project Features]
1. The super-large picture can be viewed. In general teaching, the school uses a glass bead curtain. In this case, a 120-inch white plastic fluorescent curtain is installed, which enlarges the viewing angle of the picture without reducing the curtain gain. It avoids the phenomenon that students on the back row cannot see the demonstration picture clearly. At the same time, the white plastic curtain is better than the glass bead curtain in expressing the contrast of the picture.
2. Projector with high brightness and high color reproduction. The projector is the core equipment of the projection classroom, and the projection brightness becomes an important factor that affects the use effect. In this case, the PB8245 projector designed specifically for the education market is used. It is a high-end product of the BenQ projector for the education market. The brightness of 2600 lumens and the contrast ratio of 2000: 1 are sufficient to display clearly under any indoor light source Out of the picture details, the high performance positions the high grade of the projection classroom. In order to reduce the impact of dust, a dust filter is specially installed according to the environmental conditions of the school. At the same time, in response to the diversity of teaching content, PB8245 also uses BenQ's unique golden color wheel technology, the color reproduction ability is perfect, and can buy any course, courseware teaching. At the same time, its unique DVI interface, and subsequent upgrades of video playback and other equipment can reduce its signal loss to zero, reduce the impact of signal interference, and improve the quality of the image.
3. Simple and practical console and central control system. The console is also a teacher's podium, and the multimedia control booth is equipped with equipment and control panels that teachers need to operate during teaching, and the desk of the podium is simple and small in size. At the same time, in order to better manage and control the entire system, the central control can be equipped with an IC card. The teacher inserts the IC during the class, and the projector and curtain can be used. The teacher will unplug the IC after class and the system will automatically shut down the projector , Raise the curtain, all operations are very simple, easy to maintain and manage. The delayed power-off function provided by the central control provides an additional insurance for your equipment.
