Double screen lifting paperless conference system
Paperless meeting system framework
1. The multimedia conference room is a multi-purpose venue mainly for conferences, speeches, academic experience exchanges, internal commendation meetings, news and product launches. Therefore, the following systems and functions are required:
Paperless conference system;
Conference discussion system;
Conference sound reinforcement system;
We conduct a detailed plan analysis for the above-mentioned subsystems.
2. Paperless conference system
Boao's paperless system is a collection of conference manuscript release, manuscript review, original handwriting annotation, modification, signing, simultaneous viewing of speeches, same-screen interaction, conference service application, participant exchanges and interaction, conference voting, conference control and other functions As an integrated multimedia conference platform. Through the use of mobile tablet terminals or integrated business terminals for business lifting, the conference organizers can save paper and human resources, and truly realize an environmentally friendly, energy-saving, paperless, efficient, and interactive intelligent electronic conference mode.
Through this set of professional conference products, on the one hand, it is possible to "liberate" the vast number of conference organizers within the unit; on the other hand, the application of mobile information technology greatly improves the efficiency of the organization and helps conference organizers greatly reduce work pressure. Easily carry out on-site management and control of the meeting, continue to reduce costs and save time, bring the upgrade of internal management level, and also provide more detailed meeting information for the majority of participants, so that users can obtain comprehensive, efficient, real-time and safe Meeting services, get ubiquitous meeting information experience. At the same time, it saves a lot of printing costs and projection equipment for office units, which is fully in line with the national low-carbon and environmental protection concept.
3. Conference discussion system
The system realizes unified management of the conference speech process through the conference system host, and all microphones in the system are connected in series with single-wire connection technology, and finally to the conference host, as if holding hands. During the exchanges of medium and large group meetings, there are many speakers at the meeting, and the single-line connection technology can ensure that everyone speaks conveniently and at the same time facilitates meeting management. Digital conferences are installed in embedded and desktop formats.
The hand-in-hand conference discussion system can realize functions such as chairperson priority and speech control. The control and management mode of the conference system can be set to automatic or manual. When it is set to manual mode, the delegates of the conference need to apply in advance on the delegate machine when they speak. Participants can continue after their speeches, or the chairperson is authorized to speak, and as the conference chairperson, they can achieve priority functions and cut off the speeches of other representatives.
4. Design of sound reinforcement system
In view of the importance of the conference room system engineering design and the need for the audio sound reinforcement system to adapt to different types of meeting formats, in order to make our design more rigorous and accurate, for the sound reinforcement system design method, we use the acoustic simulation software EASE4.1 The method of on-site acoustic simulation design can better improve the design of on-site sound reinforcement. EASE4.1 Acoustics Computer Aided Design Software can perform sound field simulation design (including live podium, listening area model establishment, material pasting, speaker suspension and sound field simulation, etc.).
When designing with EASE4.1 software, we can carry out computer-aided design according to CAD architectural drawings: for the acoustic characteristics of the audience sound reinforcement system, according to the design method and calculation requirements of Article 22.3 of the "Civil Building Electrical Design Code", we adopt At present, the world's most advanced and latest acoustic computer-aided design (CAD) design software "EASE4.1" has been designed and calculated. The design calculation results are given in the form of a color display diagram of the sound field distribution.
According to the drawings and design research of the conference hall, it requires high clarity and language intelligibility for speech sound reinforcement. Therefore, the main speaker adopts a long-stroke active digital speaker array with a controllable full-frequency beam for sound field design. The sound system can radiate powerful direct sound to the listening area and avoid spreading to other sound reflection areas outside the listening area to meet the needs of high-quality listening. Therefore, in order to meet the high-standard construction needs of this conference hall, under the existing conditions, we adopt the optimized sound reinforcement method of the left and right channel configuration conference full-range speakers, and also configure the ceiling speaker group to achieve multi-purpose sound reinforcement. effect.
