Multimedia Conference System in the Report Hall of Judicial Organs-Scheme Construction


System Overview:
The construction of the multimedia conference system in the report hall of the judicial organ is closely related to the development of the times and the actual needs. It can meet the informatization needs of the judicial organs, cross-regional cooperation needs, real-time and effective communication needs, and can improve meeting efficiency and cost savings. These factors promote the judicial organs to build a multimedia conference system, so as to improve the quality and efficiency of work, and better serve the development of judicial affairs.

 

Demand analysis:
Conference room for language sound is mainly clarity and intelligibility requirements, but also requires a certain degree of loudness, so that it sounds effortless. At the same time, the spectrum is required to be balanced and not distorted. For music, in addition to the requirements of clarity and loudness, there are also requirements for fullness, space and balance. It is generally believed that good sound quality should have appropriate loudness; it has a certain sense of space; it has good timbre (that is, low, medium and high frequency parts are well balanced, and the timbre is not distorted or distorted). Therefore, the sound quality of the sound reinforcement system has the following requirements:
The fullness of the sound: fullness refers to the enhancement and contrast effect of the direct sound due to the reflection of each interface when listening to the sound in the hall. An acoustically designed hall should feel thick, round, warm and elastic, with a sense of intimacy. Therefore, we strive to make the electric sound reinforcement system of the multi-function hall work in the full field, from the acoustic point of view, it should have sufficient loudness and brightness, medium and high frequency sound is appropriate, bright but not stinging, medium and low frequency energy is sufficient, and the transient response is good. What a great.
The bright and clear sound: the bright and clear sound mainly refers to the high-frequency components in the sound, and the attenuation is slow, and there are rich high-order harmonics. This is of great help to the expression of language and the level of music, giving the audience a feeling of clarity and transparency, just like a Tan Qingshui, looking to the end. What a great.
Sound energy distribution is uniform: the sound energy distribution of each point in the whole hall is uniform, that is, the sound field is evenly distributed, which can ensure that the loudness of the audience in each area is basically the same. In the hall with uniform sound field, the difference between the maximum sound pressure level and the minimum sound pressure level shall not exceed 6dB, and the difference between the maximum sound pressure level (or the minimum sound pressure level) and the average sound pressure level shall not exceed 3dB. In the sound quality design, the following measures can be taken to make the sound fully diffused, and the sound energy distribution is relatively uniform. And so much.
Appropriate reverberation time: the quality of the hall is very close to the reverberation time. Choosing the right reverberation time can improve the clarity of speech and the fullness of timbre. The near-reflection sound helps to strengthen the direct sound, especially the reflection sound from the side wall in the hall, which plays an important role in the sense of space and the sense of the sound. In large halls, near-subreflection sound can be used to make the sound field uniform. And so much.
Control of noise and feedback: in the design of the hall sound reinforcement system, the most headache is the background noise of the system and the feedback feedback of the microphone. In terms of sound construction, as the target place is irregular cuboid, it is easy to form the generation condition of simple standing wave. Therefore, we suggest that the owner should fully consider the design of sound construction materials and use surface decorations with appropriate sound absorption coefficient when decorating the hall, in order to obtain moderate early reflection sound, avoid harmful reflection sound, and reduce the sound field conditions of acoustic feedback.

 

Design ideas:
Equipment selection is based on the principles of international advanced, economically reasonable, safe and reliable use, convenient and fast maintenance. Ensure a good on-site sound reinforcement effect, ensure that the venue has a higher clarity, and provide more, more convenient and reliable expressions for the participants. We design the whole system with the idea of practicality, convenience, diversity, advancement, scalability, openness and security.
• Practicality:
To the maximum extent to meet the requirements of the actual work, to meet the user's business management as the first element of consideration, the use of centralized management and control mode. According to the actual needs to design the corresponding system, on the basis of meeting the functional requirements and technical indicators as far as possible to simplify the design, adhere to the practical, fully meet the needs of users.
• Expanding, maintainability:
To reserve space for the future upgrade of the system, system maintenance is the largest proportion of the entire system life cycle. It is necessary to fully consider the reasonable and standardized structural design. The maintenance of the system can be completed in a very short time. The project should have a good overall audio-visual effect, appropriate style and style, all products should be selected from domestic and foreign regular manufacturers, and accompanied by a product certificate.
• Economy:
Under the premise of ensuring the advanced, reliable and high performance price ratio of the system, the most economical goal is achieved by optimizing the design.
• Forward-looking technology:
Considering the future status of the system, forward-looking technologies and systems should be used in the design. The system structure is advanced, open system structure and the use of scientific system, the whole system can reflect the development level of today's sound reinforcement equipment.
• Availability and flexibility of system equipment:
It can meet the requirements of actual work to the greatest extent, consider meeting the owner's management as the first element, adopt the mode of centralized management and control, and meet the functional requirements on the basis of convenient operation, simple maintenance and simple management. Pursue the best investment effect ratio of less investment under the premise of satisfying the function.

 

Functional advantages:
Provide high-definition audio and video: The multimedia conference system can provide high-definition audio and video effects, so that participants can clearly hear and see other people's speeches and presentations. This can improve the communication effect of the meeting, let the participants better understand the content of the meeting, and improve the participation.
Realize remote conference: The multimedia conference system can connect the judicial organs in different locations through the network, so that it can conduct remote conference. This saves time and money, reduces unnecessary travel and travel expenses, and improves productivity.
Support a variety of meeting forms: The multimedia conference system can support a variety of meeting forms, including one-to-one or one-to-many exchanges, group discussions, speeches and presentations. It provides the opportunity for flexible selection, enabling the meeting to take different forms and modes as needed.
Information sharing and collaboration: The multimedia conference system enables information sharing and collaboration among participants by sharing files and screens. This not only improves the efficiency of the meeting, but also promotes cooperation and interaction among participants.
Convenient and easy-to-use operation interface: multimedia conference system usually provides convenient and easy-to-use operation interface, so that users can easily master the use of the system, and can quickly switch different functions and modes, improve the efficiency and fluency of the meeting.
Security and confidentiality: The multimedia conference system can provide secure network connection and data transmission to ensure the security and confidentiality of the conference content. This is very important for the judiciary because they need to deal with sensitive legal information and cases.
