Campus Broadcasting System Construction Scheme


Campus Broadcast-- Program construction


System Overview
The digital IP network broadcasting system adopts the TCP/IP network technology widely used in the world today, and transmits the audio signal in the form of data packets on the local area network and wide area network, which completely solves the problems of poor sound quality, complex maintenance and management, and poor interactive performance of the traditional broadcasting system. The system equipment is simple to use, easy to install and expand, just connect the digital broadcasting terminal to the computer network to form a powerful digital broadcasting system.

demand analysis
Requirement 1: The power supply of the broadcasting system is unified and cannot be controlled by the main power switch in the classroom;
Requirement 2: Set up sub-control room according to actual requirements;
Requirement 3: The classroom can be organized at will to facilitate the classification of grade groups;
Requirement 4: The broadcasting system software can use Pinyin input method and five-stroke input method to input text for editing instructions;
Requirement 5: Save a certain number of broadcast system instruction templates, and some broadcast system instruction templates can be automatically switched to execute according to the set time;
Demand six: mobile phone or computer can remotely control the broadcast system software, edit and modify the instructions;
Demand seven: in the holding of important examinations, such as the high school entrance examination when the broadcast system can achieve double insurance backup broadcast;
Demand eight: linkage with the school fire protection system, in case of fire or other emergency situations, realize the emergency alarm broadcast to inform the school teachers and students to evacuate the scene;.

Design Ideas
Implementation 1: Separate power supply to the classroom broadcast speakers in the teaching area, IP addressing speakers, power amplifiers, switches and other equipment in the network broadcast part, which are all led to each classroom by the host computer room and are not controlled by the power switch on the floor where each classroom is located;
Implementation two: according to the actual needs to set up sub-control room, each broadcasting station is equipped with sub-control computer, network paging intercom microphone, mixer and network audio encoder;
Implementation 3: The classroom in the teaching area adopts IP network broadcast addressing wall-mounted sound box auxiliary box, which can not only realize independent control, but also carry out unified broadcast and regional broadcast, thus flexibly meeting actual needs; The dormitory area and public area adopt IP network decoding terminal power amplifier sound box, and different music is played in different areas at the same time in public area according to needs;
To achieve four: broadcast system software supports Pinyin input method and five input method, and can be switched at will;
Implementation 5: There are 1000 broadcast system instruction templates that support saving. Multiple broadcast system instruction templates can realize timing switching function, and instruction templates can be copied;
Implementation 6: The broadcast system sub-control software/mobile phone software can run on any computer/mobile phone on the broadcast network, providing a remote operation platform for broadcast administrators and users of the broadcast system;
Implementation 7: The CD player power amplifier IP network broadcast addressing wall-mounted sound box constant pressure backup module is used to realize that when single or multiple devices in different areas are out of network or power failure, the analog backup system replaces the IP broadcast system for non-delay broadcasting. At the same time, if the main power amplifier fails, the main-standby switch will switch to the standby power amplifier immediately when it detects an abnormal signal and continue the English listening test;
Implementation 8: Configure the IP network alarm host to interface with the school's own fire fighting system. When the fire fighting system receives an emergency signal, it will instantly activate the IP network alarm host. The network alarm host will alarm in zones, regions and layers according to corresponding settings, and cooperate with linkage output to trigger other equipment to carry out emergency actions.
