Scheme Description:

With the rapid development of information technology, the number of new products and technologies is increasing day by day. Therefore, this system should make full use of the latest technology in the case of investment cost permission, so that the system as long as possible in the period of time and social development adapt. So the design must be forward-looking and scalable. This scalability not only fully protects the investment of Party A, but also has a high comprehensive cost performance. This design has made full consideration to this, reserved a variety of interfaces, very easy to expand and upgrade the system. IP digital broadcasting is different from general broadcast system, is an advanced and powerful comprehensive system engineering, system design must be safe, reliable, the optimal configuration, construction, installation, debugging, the whole process in strict accordance with the relevant national standards and norms, to do a good job of standardized design and scientific management system.

Case application:

1, line multiplexing capabilities: IP digital broadcasting system, USES the pure digital IP network transmission, and general TCP/IPV4 compatibility, can be run in LAN, wan, adopts distributed structure, the various IP network broadcast equipment layout school, the school teaching building, office building, library, playground, etc., using the original campus private network connects devices, IP network broadcast system of new campus, without rewiring, greatly saves the wire rod cost and construction cost.


2. Simple operation and convenient expansion: IP digital broadcasting system adopts distributed structure, each terminal can run independently in the network, or can be run in a network, the overall structure is very simple. If the system needs to be expanded, it only needs to connect the newly added various network terminals to the campus network, without additional wiring and construction. The master server management operation is also very convenient, touch screen programming operation, can also be connected to the keyboard and mouse operation, more powerful one-button deployment function, each terminal will be added to the master server operation interface.


3, system and emergency center linkage function: system in the computer room configuration IP network signal acquisition unit, when receiving the emergency center sent the emergency signal, system real-time broadcast sirens or emergency evacuation command password, there is other radio signal automatically blocked or forcibly boot device are in a dormant state of the system. The device can operate independently from the main server, or it can be distributed anywhere in the network to collect emergency signals, issue sirens or forcibly start sleep devices.


4. System backup function: The IP digital broadcasting system has dual backup function: Off-line and off-network backup: When the system is debugged for the first time, the timing programming task is downloaded to each terminal. When the server is down and the network is down, each terminal can play the pre-downloaded programming program through the built-in SD card, so as to ensure the normal playing of the clock and the background music.


5, Automatic programming and playback function: the system has multiple sets of timing task management schemes, supporting multi-mode operation of timing task. The timing task can be controlled by weekly cycle or executed by day. Through flexible configuration of timing task, it is fully suitable for various complex applications. At the same time, the main server has a rich source of programs, such as all kinds of bells, gymnastics, etiquette songs, all kinds of sirens, etc., which can be called and played at any time.


6. Peer-to-peer playback function: all devices in the system can be identified by IP address setting. Each classroom terminal has its own independent IP, which accepts the system's timing programming and independent playback. The system can set up multiple functional groups with different names, and each classroom terminal can belong to multiple groups at the same time. Such as in the middle school campus, first class 1, it can belong to the first grade group, can also belong to the middle group (first, second, third for the middle group, different from the high school group). The system can be programmed to play specific program sources by groups, and groups can play the same or different programs at the same time.


7, sub-control function: the system supports multi-point distribution control function, only need to install IP digital broadcasting system sub-control software on the ordinary PC, you can manage the entire system operation. At the same time, the system supports the function of mobile phone APP sub-control. Any Android phone with IP digital broadcasting system APP sub-control software can manage each terminal.


8, remote paging function: the system can be configured with multiple IP network touch paging platform, respectively arranged in the school, the school main room, the principal's office, teaching office, grade leader's room, gatekeeper's room and other places that need to interrupt the notification. School leaders can pager the entire school or pager a single school, multiple zones or groups to speak, play local programs; Each paging platform can also intertalk with each other, support PCM uncompressed audio format, and the delay is close to 0 millisecond, the sound is clear and smooth without lag.


9. Local sound amplification, seamless integration with audio-visual multimedia system: classroom terminal equipment, in addition to receiving any program source broadcast in the network, also has line input function, can be connected to the audio-visual multi-media computer in the classroom program source amplification; At the same time, the terminal equipment of the classroom has the function of 2.4G microphone, infrared laser pointer and PPT page turning function, which can amplify the teacher's voice through the classroom speaker, greatly reducing the burden of the teacher's voice when lecturing.


10, campus radio station functions: the system is configured with a digital IP network mixer, which can access multi-channel microphone and multi-route input, programmable playback mixer with built-in SD card program source, can be mixed output. In peacetime, the campus announcer will broadcast all kinds of entertainment programs to create a comfortable campus environment for all teachers and students. In the school sports meet, the use of wireless microphone can be used to broadcast the sports meet and the site of the athletes voice interview.


11, high sound quality, low delay function: the system adopts network data packet transmission mode, can close to CD-level sound quality, support all the current mainstream audio formats such as PCM (uncompressed format), ADPCM, MP3, WAV, OGG and other program sources.
