The construction of the computer room of the Beijing No. 4 Middle School Student TV Station project should conform to the national radio and television project construction standards, which mainly include construction standards, engineering technical specifications, engineering cost quotas, investment estimates and protection spacing standards. For the construction of the computer room and studio, please refer to the "County-level Radio and Television Engineering Construction Standards". See GY / T 5064-1999 (Engineering Construction Standards Compilation 10). 1. Part of the design instructions for the computer room construction project: According to the field survey, the school TV station room environment is hexagonal, and two sides are single-layer profile glass windows. The room embodies three functional areas: editing machine room, studio, and teacher's office. Consider the studio shooting space, the teacher's office lighting, the easy access to the editing room and campus network; see the layout: Between the studio and the editing room and the teacher's office, sound-absorbing and sound-absorbing walls (irregular twists, high-pitched cavity, bass cavity, sound-absorbing cavity) and sound-proof observation window (double-layer inclined), sound-proof door (central sound-proof steel plate, sound-absorbing sponge, soft Bags, trapezoidal wedges) anti-static and flame-retardant carpets on the ground, and curtains (sound-absorbing, flame-retardant) covering the windows to ensure an acoustic environment. The anti-static floor is installed in the editing room and the teacher's office, embedded cable tracks (audio, video, power supply, grounding copper wire), sound-absorbing panel ceiling, primary soundproof partition wall. Before the site reconstruction 2. Description of design of studio lighting system: The studio is a small studio, and the scenic spots are in the form of special topics and interviews. The overall lighting system uses three primary colors of cold light source lamps; ring-shaped lighting is the main, three-point lighting assists the integrated lighting method; the hanging device (fixed sliding track) is used to configure the lamp hanging system. It is the most advanced and practical lighting mode in China. It not only achieves beautiful and practical, outstanding effect, but also does not waste capital. It can fully meet the requirements for the production of news, special topics, interviews (1-2 people) and other types of program production. The characteristics and configuration of its lighting mode mainly include the following aspects. 1. Lamp system: A new three-color cold light source lamp is used. The light is even and delicate, and the light distribution method is flexible and changeable. Meet the needs of the production of light. It shows the texture and three-dimensional sense of the objects and characters. Therefore, it lays a good foundation for the post-production of the program. 2. Hanging system: Considering the height of the room in this studio, the sliding single-layer track and hanging device are adopted in the track design, so that the lights can move left and right, up and down, and freely. The reasonable suspension system is configured on the suspension and structure, adapts to the variability in lighting, and provides a reliable guarantee for lighting lighting. Through the use of users at all levels in recent years, it has fully demonstrated its superiority. 3. Control system: The cold light system in the studio area is controlled by a single lamp and a single circuit, and a separate distribution box is more convenient and random in the comprehensive light distribution. Suitable for teachers and students to operate. 4. Wire and cable: The wire and cable used in the studio are all special flame retardant cables for film and television. The circuit design uses complete separation of strong and weak currents, reducing the hidden danger of line failures, avoiding the interference of strong currents on DMX512 signals, other weak current signals, and video signals, and fully meeting the requirements of power circuits for TV studio projects. This design plan complies with the "Specifications for the Design of the Lighting System of Television Studios" promulgated by the General Administration of Radio and Television of the People's Republic of China, GY / T155-200 "Standards of the People's Republic of China and the National Radio, Film and Television Industry", GY / T5212-1997 "Cable Broadcasting The system installation project budget quota preparation and use instructions ", GYJ33-88" Radio and Television Engineering Building Design Fire Standard "data requirements, and combined with the actual situation of your studio design. After the site reconstruction 3. The budget table of the computer room construction project and the studio lighting system (omitted) Finally, as a complete solution, it is necessary to consider background scenes, tables and chairs for shooting, artificial plants, etc. in the studio, as well as student chairs that match the editing desk.
