Paperless office system decoration requirements:
  First, the overall design idea of ​​the conference room (paperless conference system)
  The layout of the conference room/classroom should be generous and simple, which can realistically reflect the scene characters and the conference environment, so that the participants have a sense of presence and unity to achieve good results in visual and language communication. Images transmitted in remote conference rooms/classrooms, including people, scenes, graphics, text, etc., should be legible. The temperature, humidity and air circulation of the meeting room should be kept in the remote conference room/classroom to make the participants feel comfortable and natural.
  Second, the conference room layout requirements
  In order to ensure the viewing effect of the multimedia conference system image and prevent the "glare" or "reflective" effect of the color on the person's camera, the background wall should adopt a single uniform light color, and other walls, tablecloths, carpets, ceilings, etc. of the conference room should be The background walls match and the background wall should not be used. It is recommended that the tables, chairs and walls be in beige or light cyan. Chairs should not be sofa-style, nor should they have a high backrest to avoid blocking the participants behind.
  A major factor affecting the quality of the picture is the scenery and color around the venue, as well as the color of the tables and chairs. Generally, the colors such as "white" and "black" are banned. These two colors will have adverse effects on the human body, such as "reflective" and "light-recovering". Therefore, no matter whether the walls, tables and chairs are light-colored, it is more suitable, such as beige, light green, light brown table and chair, etc., the south should use cool colors, the north should use warm colors. It is not appropriate to hang landscapes such as landscape paintings on the background of the camera (the wall behind the subject), otherwise the amount of information of the camera object will be increased, which is not conducive to the improvement of image quality.
  Third, meeting room acoustic requirements (microphone lifter)
  In order to ensure the sound insulation and sound absorption effect of the multimedia conference system, carpets, ceilings and surrounding walls are equipped with soundproof blankets. The windows should be double-glazed. Sound insulation should be considered when entering and leaving the door. At the same time, do not overdo it, and avoid the sound dry up.
  According to acoustic technical requirements, a certain volume of conference room has a certain reverberation time requirement. Generally speaking, if the reverberation time is too short, the sound will be dry and dry; the mixing time is too long and the sound is confused. Therefore, different conference rooms have their best reverberation time. For example, if the reverberation time is right, the speaker's voice can be beautified, the noise can be covered, and the effect of the conference can be increased. The speakers should be arranged so that the conference room has a uniform sound field and prevents sound back. The power amplifier of the sound reinforcement system should be set in the same venue by using several small-capacity power amplifiers. With reasonable wiring and switching system, the conference room will not interrupt the sound of the venue when it damages a power amplifier. Before the sound signal is input to the power amplifier, it should be processed with an equalizer and a feedback suppressor to improve the quality of the sound signal.
  The establishment of a good listening environment, including the two aspects of architectural acoustics and electroacoustic; the sound of the sound in the professional sound engineering is mainly the sound of the hall, the same level of equipment to play the same level, generally It is the difference in the conditions of the sound construction. No matter how good the equipment is, once placed in an environment with poor sound conditions, it will certainly not achieve good results; and the sound requirements will vary depending on the requirements of the project, and will also be affected by the quality of the building decoration. Halls with good sound conditions should have reasonable reverberation, good sound diffusion, no sound focus, no audible vibration noise, no sound shadows, no sound standing waves, etc. The requirements for sound construction cannot be unilaterally provided by sound designers. To carry out, it requires the strong cooperation of the building decoration technicians.
  The special purpose of the function room, the sound must be clear and full. The propagation of sound waves in the room can be divided into direct sound and reflected sound. When the sound is reflected indoors multiple times, a reverberation sound is formed. A suitable reverberation time makes the sound loud and round. For music signals, the best reverberation time makes the music harmonious and pleasing. If the reverberation time is too long, it is like speaking in a closed corridor, the sound will become blurred and the clarity will be reduced. If the reverberation time is too short, such as singing or playing outdoors, the sound will become dry. Powerless, dull and monotonous. In order to achieve good sound effects in the room, the indoor reverberation time must be coordinated. The multi-function hall should focus on the clarity and intelligibility of the language, and ensure that the student's seat has sufficient loudness. The reverberation time is 1.2 seconds. The treble of the corresponding amplifier should be improved, and the bass should be reduced.


Fourth, meeting room lighting requirements
  The lighting design of the video conference room is a key factor in achieving a satisfactory visual effect. In addition to providing a comfortable meeting environment for conference attendees, the well-designed video conference room can achieve a better sense of presence and improve the effectiveness of video conferencing. Video conferencing is different from ordinary conferences. Because of the use of camera devices, the lighting, color, and background of conference rooms have a great impact on the quality of video images.
  Meeting room lighting design requirements
  1. Illuminance: The illuminance of the lamp is a basic requirement for the video conference room. Since the time of the video conference is random, the artificial cold light source is applied indoors to avoid natural light. The windows and doors of the conference room should be covered with dark curtains. The light source has no adverse effects on human vision. It is more appropriate to choose a three primary color lamp. The illuminance requirements are as follows:
  A) In order to ensure correct image color and camera self-balancing, it is stipulated that the light shining on the face of the participant is uniform, and the illumination should be no less than 500 lux. The illumination near the monitor and projection TV is 50-80 lux, and direct light should be avoided.
  B) The direction of the light is more important than the intensity of the light. A diffuse lens is installed for the light to diffuse the light sufficiently to give the participants a uniform illumination.
  2, multimedia conference system installation location requirements: Three primary color lights are generally installed on the ceiling of the conference room, to install the L-shaped frame on the ceiling, the lamp is installed at the corner of the L-shaped frame, so that the light does not directly shine on objects and participants, The reflection and scattering of the light by the ceiling illuminate the conference room.
  In addition to the above two points, in order to achieve better results, you need to pay attention:
  A) Avoid direct sunlight on objects, backgrounds and lenses, which can lead to strong contrasts in glare.
  B) Auxiliary lighting is recommended when the light is weak, but avoid direct lighting.
  C) Using auxiliary lights, it is recommended to use daylight type lights. Do not use colored lights to avoid using strobe sources.
  D) Avoid direct illumination from the top or out of the window, which directly causes shadows.
  E) It is recommended to use indirect light sources or softer light reflected from a flat wall.
  3, layout principle: to ensure the multimedia conference system camera effect to achieve the purpose of reproducing clear images.
  Layout requirements:
  A) In order to prevent the color and the light-reducing effect of the person's camera, the wall should be designed separately. It is best to use a uniform light color. Usually, it is beige or gray. It is not suitable to use the frame. It is forbidden to use the contrasting color. To facilitate camera lens aperture setting.
  B), the other three walls, floors, ceilings, etc. of the room should match the color of the background wall. Avoid the saturated color of black or bright colors, usually light blue, light gray, etc. It is not suitable for each wall to use complicated patterns or to hang complex frames to avoid blurring of the image when the camera is moved or zoomed, and to increase the coding overhead. It is best to seal the windows or install tinted glass, or hang thick curtains to prevent direct sunlight.
  C), the camera lens should not be aligned with the door. If the door is used as the background, the entrance and exit of the personnel will cause the camera lens to expose the light source behind the camera.
  D), conference table (electronic table card): the conference table layout is better. At the same time, to reduce facial shadows, the conference table recommends a light-colored tabletop or tablecloth.
  Five, meeting room power supply system requirements (ultra-thin one lift)
  In order to ensure the safety and reliability of the conference room power supply system and to reduce the electrical crosstalk caused by the power supply path, three power supply systems should be used. A power supply system is used as the lighting for the conference room; the second power supply system is used as the power supply for the entire terminal equipment and control room equipment, and the uninterruptible power supply system (UPS) is used; and the third power supply system is used for power supply of the air conditioner.
  Grounding is a more important issue in power systems. The ground wire required for the control room or machine room and conference room should be connected to the grounding busbar installed in the control room or machine room. If the grounding body is separately set, the grounding resistance should not be greater than 4 ohms. When it is difficult to set up a separate grounding body, the grounding body can also be used with other grounding systems. The grounding resistance should not exceed 0.3 ohms.
  Paperless multimedia conference room project It is a comprehensive high-tech technology project that combines codec, photography, lighting, sound, network, weak electricity and strong electricity. Therefore, even if a high-end multimedia conference system terminal device is selected, a good video effect cannot be achieved without a good and stable operating environment.
