Project design requirements of campus IP network broadcasting system
The campus IP network broadcast system requires advanced and practical functions such as timed broadcast, terminal on-demand, temporary broadcast, and sub-control control. It has a software operation interface. Terminals and partitions can be combined at will, and reorganization can be realized at any time through the control software interface;
The daily campus broadcasting system mainly uses background music and teaching bells, student broadcasting stations, mainly for relaxing music playback, through the installation of outdoor sound columns on both sides of the campus building, during normal teaching broadcasts and campus classes and after classes Play light music with clear and beautiful sound effects and even coverage, creating a leisure environment for the campus. At the same time, the sound size should be appropriate to ensure that it does not affect normal conversations;
Each classroom in the teaching building is set up with an independent broadcast point, and each classroom is independently partitioned. It can broadcast independently and control the broadcast program independently. In the broadcast room, it can broadcast to any one or more classrooms;
Design effect of campus IP network broadcasting system
The design of the school background music system is combined with user needs, based on the principles of practicality, advancement, reliability, openness, compatibility and standardization. The school broadcast system design mainly meets the two parts of campus broadcast and fire protection broadcast, and can mainly achieve the following effect:
Background music broadcast:
1. School Broadcasting Room: The core of the IP network broadcasting system, which realizes functions such as regular ringing, background music, test English listening, etc., as well as two-way intercom and remote calling with IP network broadcasting terminals.
2. Classroom area: In the core area of ​​the school, an IP network broadcast terminal is set up in each classroom, remotely operated to realize network courseware playback, and has the functions of rapid positioning, repeating, and speed changing.
3. Broadcast notification: The leadership office can conduct broadcast intercom or call out. The central broadcast of the control broadcast room can be set to realize the remote broadcast notification of the leadership.
4. Sports field: the main place for student activities, to achieve the broadcast requirements of morning exercises and sports meets, in the playground broadcasting room can realize the leadership of remote speech; outdoor wireless operation, remote wireless broadcasting and other functions, to meet the use of outdoor squares, sports fields and other areas:
Campus IP network broadcast function:
1. Grouping control: All network terminals can be broadcast in arbitrary groups, which greatly enhances the flexibility of terminal management.
2. Real-time tasks: real-time playback and real-time acquisition and playback can be realized; the contents of the computer media library and the real-time acquisition and playback of external audio sources can be played anytime and anywhere.
3. Timing ringing: In response to ringing needs at a specific time and in a specific place, you can customize a variety of ringing programs.
4. Timing playback: collect specific peripheral audio sources within a specific time and play them to a designated area, and the system provides peripheral control interfaces.
5. On-demand function: It can realize the on-demand of remote media library files, and perform operations such as play, pause, fast forward, rewind, previous song and next song.
6. Intercom function: Two-way intercom and full-duplex working mode can be realized between broadcast terminals.
7. Fire linkage: The system can be seamlessly connected with the fire alarm system to realize broadcast fire alarm.
8. Broadcast recording: Real-time recording of broadcast content can be realized and used as audio data for storage.
Main features of campus IP network broadcast:
1. Fast system construction
Where there is an IP network, just connect to the IP network broadcast terminal equipment; where there is no IP network, it is relatively quick to build a simple IP network.
2. Good broadcast sound quality
The program transmission of the IP network broadcasting system adopts an all-digital method, which is not affected by the transmission distance or the environment, and listeners can enjoy high-fidelity sound quality.
3. Systematic maintenance
The equipment of the IP network broadcasting system is concise, and the network broadcasting terminal equipment adopts an embedded system to be solidified on the processor chip, which is free from viruses and can provide remote maintenance without a lot of maintenance work.
4. Easy system management
The system administrator can set up timed broadcast tasks for different users and different partitions in advance, and the system will automatically execute them when the time comes, so people are truly on duty.
5. As long as the users of the Broadcast Easy Broadcasting System are authorized by the system administrator, they can broadcast programs to designated areas on their own computer sub-control stations, or they can set up timing tasks to automatically play without running around for help.
6. Many sub-control sites
All computers on the IP LAN can be used as sub-control sites to manage or use the IP network broadcast system. As many broadcast sub-control stations can be established as many computers on the LAN.
7. Many broadcast zones
Each network broadcast point in the IP network broadcast system is an independent IP network node, with its own independent IP address, and can form an independent broadcast partition by itself. Each network broadcast point can belong to multiple zones at the same time. The change of the partition does not involve any physical changes.
8. Many programs
In the IP network broadcast system, each broadcast program is a group of IP data packets, and different broadcast programs can be broadcast simultaneously on a network cable without affecting each other. The bandwidth of CD-quality audio files is only 128KBPS. When 100 channels of different CD-level programs are broadcast at the same time, the bandwidth occupied is only 13M, which is less than 15% of the 100M LAN.
