The conference room is a place for meetings and also a place to place conference TV equipment. Therefore, the rationality of conference room design determines the quality of conference TV images and directly affects the efficiency of the conference. A complete video conference room planning and design can not only provide a comfortable meeting environment for participants, but more importantly, it can realistically reflect the people and scenery at the scene (venue) and give participants a sense of presence, so as to achieve good results in visual and language communication. Images from the conference room should include people, landscapes, charts, words and so on.
Two. Type, size and environment of meeting room
1. Type of meeting room
The types of meeting rooms are classified according to the nature of the meeting, and are generally divided into public meeting rooms and professional meeting rooms. Public meetings are suitable for opening to the outside world, including administrative work meetings and business meetings. This kind of meeting room is well equipped, mainly including TV, microphone, speaker, controlled camera, flat camera and auxiliary camera (scene shooting, etc.). ). If the venue is large, it can be equipped with a projection TV (rear projection is preferred). The special meeting room mainly provides academic discussion, distance teaching and medical consultation, so in addition to the above-mentioned public meeting room equipment, teaching and learning equipment can be added as needed, such as whiteboard, video recorder, fax machine, printer, etc.
2. Meeting room size
The size of the conference room is related to the video conference equipment and the number of participants. According to the number of people who usually attend the meeting, apart from deducting the distance from the first row of seats to the display equipment behind the podium, the space occupied by each person can be considered as 2m2, or even relaxed to 2.5m2 per person. The ceiling height should be greater than 3m2.
3, the environment of the meeting room
The temperature and humidity of the meeting room should be suitable, generally considered as room temperature 18 ~ 25℃, and the humidity of 60% ~ 80% is reasonable. In order to ensure suitable indoor temperature and humidity, an air conditioning system can be installed in the conference room to realize the functions of heating, humidification, refrigeration, dehumidification and ventilation. The meeting room requires fresh air, and the number of air changes per person per hour shall not be less than 18m3. The environmental noise level of the conference room is required to be 40dB(A) to form a good conference environment. If the indoor noise is too loud, such as the noise of air conditioning, it will greatly affect the performance of the sound system, and other venues can't hear the speech clearly.
Third, the layout, lighting and sound effects of the conference room
In addition to the required layout, the conference TV room can be flexibly arranged. The following figure shows the layout of a typical TV conference room:
The display equipment of the whole conference room is divided into two parts. One part is the projection (or rear projection TV) behind the rostrum, which is responsible for providing the participants with the images of this venue and another venue. The other part is the four TVs in front of the rostrum, which are divided into two groups and are responsible for displaying the images of this venue and another venue for the leaders of the rostrum.
Image acquisition equipment is also divided into two groups. The main camera is installed in the center of the venue to capture the image of the rostrum in real time, and another set of panoramic cameras is installed in front of the conference room to take a panoramic view of the venue. Both sets of cameras should be controlled cameras, which can be controlled by conference television equipment.
A pair of speakers should be installed in the front and back of the conference room. In order to get better sound effect, it is required to be at least one meter away from the wall and TV.
2, the layout of the meeting room
Another factor that affects the image quality is the scenery and colors around the venue, as well as the colors of tables and chairs. Generally do not use colors such as "white" and "black". These two colors will have adverse effects on people's photography, such as "reflecting light" and "stealing light". Therefore, it is advisable to use light colors around the walls, tables and chairs, such as beige, light green and light brown around the walls. Cool colors should be used in the south and warm colors should be used in the north, so the video level provided is about 0.35V V V. The camera background (the wall behind the main body) is not suitable for hanging scenery and other scenery, otherwise it will increase the information of camera objects, which is not conducive to the improvement of image quality. You can consider putting flowers, bonsai and other elegant objects indoors to increase the overall elegant, lively and harmonious atmosphere of the conference room, which is very helpful to promote the meeting effect.
Judging from the viewing effect, the layout of the display is often placed in the position relative to the center of the participants, about one meter away from the ground, and the distance between people and the display is about 4-6 times the height of the screen. Each participant's horizontal viewing angle on the display shall not exceed 60 degrees. The size of the monitor screen used should be determined according to the data rate of conference TV, the number of people attending the conference, the size of the conference room and other factors. Small conference rooms can only use 29-34 inch monitors, or a local area of large conference rooms; Large conference rooms should be dominated by projection TV sets, all of which adopt rear projection type. You can choose the size of the TV as appropriate, and it is best to place the TV in the front of the meeting room facing people.
3. Meeting room lighting
Lighting is the basic requirement of the conference room. The camera has an automatic color equalization circuit, which can provide true and natural colors. The light incident from the window (color temperature about 5800K) is higher than that of fluorescent lamp (3500K) or tricolor lamp (3200K). If there are two kinds of light sources (natural light source and artificial light source) indoors, video images of blue projection and red shadow area will be produced. On the other hand, the meeting time is random, and the illumination and color temperature of natural light sources are different in the morning and afternoon. Therefore, the meeting room should avoid using natural light sources and use artificial light sources, and all windows should be covered with dark curtains. When using artificial light sources, cold light sources, such as "tricolor lights" (R, G, B), should be selected to obtain the best effect. Avoid using thermal light sources, such as iodine tungsten lamp with high illumination. The illumination of the meeting room should be 500LUX for the camera area, such as the human face. In order to prevent the uneven light of the face (eyes, nose and full shadow), the tricolor lamp should be rotated to a suitable position, which was determined when the conference TV was installed. For monitors and projection TVs, the illumination around them should not be higher than 80LUX, but should be between 50 and 80 lux, otherwise the viewing effect will be affected. In order to ensure the readability of documents and charts, the illumination in the chart area of documents should be no more than 700LUX, and the chairman area should be controlled at about 800LUX.
4, the sound effect of the meeting room
In order to ensure the sound insulation and sound absorption effect, there are carpets, ceilings and sound insulation blankets on the surrounding walls in the room. Windows should be double-glazed and sound insulation devices should be considered when entering or leaving the door.
According to the acoustic technical requirements, a certain volume of conference room has certain reverberation time requirements. Generally speaking, if the reverberation time is too short, the sound will be dull and dry; The mixing time is too long and the sound is chaotic. Therefore, different conference rooms have their best reverberation time. If the reverberation time is appropriate, it can beautify the speaker's voice, cover up the noise and increase the meeting effect. The calculation formula of specific reverberation time is as follows:
t = KV/{ S[-2.3 LG( 1-a)]+4MV }
Among them:
K is a parameter variable of room shape, generally 0.161;
V is the room volume (usually m
S is the total surface area of indoor sound absorber (m glass
A is the indoor average sound absorption coefficient; The specific calculation method is as follows:
α=(∑Siαi+∑Njαj)/S
Where: s-total indoor surface area;
Si- the surface area of each part in the room;
αI- corresponds to the sound absorption coefficient of surface Si;
NJ- the number of people or objects;
αj- corresponds to the sound absorption coefficient of Ni.
M is the attenuation coefficient of sound in air; When the relative humidity is 70%, it is about 1000Hz0.00 12.
4000Hz0.0062
6000Hz0.0 134
8000Hz0.0200
10000Hz0.0250
T is reverberation time (s);
When the height of the conference room is about 4m, the volume is
Fourth, the conference room power supply system
In order to ensure the safety and reliability of the power supply system in the conference room and reduce the electrical crosstalk caused by power supply, three sets of power supply systems should be adopted. A power supply system is used for lighting the meeting room; The second power supply system, as the power supply of the whole terminal equipment and control room equipment, adopts Uninterruptible Power Supply System (UPS). The third power supply system is used for the power supply of air conditioners and other equipment.
Grounding is an important problem in power supply system. The grounding wire required for the control room or computer room and conference room shall be connected to the grounding bus bar set in the control room or computer room. If the grounding body is set separately, the grounding resistance should not be greater than 4W; When it is difficult to set up a separate grounding body, it can also be used in conjunction with other grounding systems, and the grounding resistance should not be greater than 0.3W It must be emphasized that in the three-phase five-wire system with common grounding mode, the protective ground wire must be the fifth wire and must be strictly separated from the AC current zero line, otherwise the unbalanced power supply of the zero line will cause serious interference to the image.
How to arrange the secretary's meeting place?
Lead: How to arrange the negotiation venue, the arrangement scheme of the negotiation venue and the arrangement of the negotiation environment are also very important. The following is how the secretary arranges the contents of the negotiation venue. Welcome to refer to it!
Choosing a negotiation environment generally depends on whether you feel pressured. If you do, the environment will be unfavorable. Unfavorable negotiation occasions include: noisy voices, extremely uncomfortable seats, too high or too low temperature in the negotiation room, being disturbed by outsiders from time to time, burnout caused by unfamiliar environment, and no opportunity to talk privately with colleagues. These environmental factors will affect the negotiators' attention and lead to the failure of negotiations.
From the point of etiquette, generally speaking, in order to arrange a good negotiation environment for partners or negotiators, which is conducive to the smooth progress of negotiations between the two sides, the following factors should be considered:
First, light. Natural light sources or artificial light sources can be used. The use of natural light, that is, sunlight, should be equipped with screens to prevent glare; When using artificial light source, it is necessary to configure lamps reasonably to make the light as soft as possible.
Second, the sound. The room should be quiet so that the negotiation can proceed smoothly. The room should not face the street, not close to the construction site, the doors and windows should be soundproof, and there should be no noise interference such as telephone ringing and footsteps around.
Third, the temperature. It is best to use air conditioners and humidifiers indoors to keep the temperature and humidity of the air at an appropriate level. The temperature is 20 degrees. C, the relative temperature is between 40% and 60%. Under normal circumstances, at least keep the air fresh and circulating.
Fourth, color. The colors of indoor furniture, doors, windows and walls should be harmonious and consistent, and the layout should be practical and beautiful, leaving a large space for people's activities.
Fifth, decoration. The venue for negotiation activities should be clean, elegant, solemn and generous. A spacious and tidy table, a simple and comfortable chair (sofa), several paintings and calligraphy with harmonious styles can be hung on the wall, and the room can also be decorated with appropriate handicrafts, flowers and markers, but it should not be too complicated, but simple and practical.
In the negotiation, if you want to get some effect from each other's cooperation, the arrangement of seats is learned. Whether negotiators should sit face to face or adopt some kind of casual seating arrangement embodies different meanings.
In business negotiations, negotiators from both sides should sit in an equal and relative position in the middle, and the negotiating table should be long, spacious, like a mirror and elegant; Other negotiators usually sit on both sides. This seating arrangement usually shows formality, courtesy, respect and equality.
If it is a multilateral negotiation, the main negotiators of all parties should sit around the corresponding seats of the round table, which is generally large and can also be placed in sections; Translators and other negotiators usually sit around their respective speakers, or they can sit behind the speakers.
Whether it is bilateral or multilateral negotiations, the size of tables and chairs should be adapted to the environment and negotiation level: the bigger the conference hall or the higher the negotiation level, the bigger and wider the tables and chairs are; On the contrary, it will bring a sense of depression or discomfort to the negotiators.
Unlike the rectangular negotiating table, the round negotiating table usually gives people a sense of relaxation. Therefore, in some relaxed and friendly meeting places, round tables are generally used. Whether it is a square table or a round table, pay attention to the orientation of the seats. Generally speaking, it is customary to think that the seat facing the door is the most influential. Westerners are used to thinking that this seat has a sense of power, while China people are used to calling this seat "the upper seat". Seats facing the door are the least influential. Westerners generally think that this seat has a sense of subordination, and China people are used to calling it "the next seat".
If you want to imply the level of power through the arrangement of seats in the negotiation, a better way is to put a famous brand on the seat, indicating that someone should sit somewhere and have some influence on everyone. It is also more social etiquette to arrange seats in the order of status in their respective groups.
The layout of the venue should consider the nature of the meeting and the number of participants, the requirements for the layout of the venue and how to arrange the venue. For example, if there are a large number of people, it is ideal to arrange an information conference in a theater style without a table or a classroom style with a table. In a problem-solving meeting, if there are not many people, the ideal arrangement is to let everyone sit around the table, which is convenient for everyone to communicate. For another example, in a training meeting, if the number of participants is small, participants can sit on the outer ring of the horseshoe-shaped conference table, which is not only convenient for communication between participants and the chairman, but also convenient for communication between participants. But if there are many people, it is best to divide the participants into several groups, and each group is surrounded by the same table. The advantage of this arrangement is that it is convenient for group discussion and comprehensive discussion.
Seating arrangement is closely related to the effectiveness of the meeting. In addition to seating arrangement, you should also pay attention to the following items when arranging the venue:
(1) First, we should decide whether smoking is allowed in the meeting place. If smoking is allowed, an ashtray should be prepared. If smoking is not allowed, the ashtray cannot appear in the meeting. In addition, you'd better put up a sign or words prohibiting smoking at the meeting place. When the number of participants is large, the seats can be divided into smoking areas and non-smoking areas according to actual needs.
(2) If the participants are not familiar with each other, you should consider whether to prepare business cards in advance.
(3) Prepare audio-visual equipment. Blackboards (whiteboards), white newspapers and even slide projectors, projectors and projectors should be used as basic tools for general meetings. However, it is necessary to pay special attention to: the text or graphics cast by the slide projector, projector, should be clearly seen by all participants and ready to use at any time.
(4) Unless it is a long meeting (meeting for more than one and a half hours), try not to provide refreshments to prevent the participants from being distracted.
(5) When the agenda is short and you don't need to take notes, you can consider standing for the meeting. ;
Are there any special arrangements for the chairs in the conference room? The arrangement of chairs in the conference room means that the seats are exquisite; U-shape means that the conference table is arranged in an open U-shape, and the chair is placed around the U-shape table; For projection, the projector can be placed at the U-shaped opening. Compared with the conference room of the same area, this type of pendulum can accommodate the least number of people. U-shaped layout is generally suitable for small and discussion meetings.
1. According to international practice, the seven on the right hand side are the largest, and the next one on the left hand side is the smallest; The closer to the theme, the higher the seat and seat; The farther away from the subject.
Second, the number of seats and the lower the number of seats. According to this principle, seats can be numbered;
Third, the method of seat numbering is: first, determine whether the seat is placed on the rostrum. In general, for meetings with higher specifications, the host and important guests can sit on the rostrum, and the first guest seat (or host seat) is generally located in the middle of the rostrum. Secondly, determine the chair seat, which can be close to the podium for easy access;
Then determine the seats of other guests and VIP audience.
