Project Overview:
The network broadcasting system of Baohu Huafu Kindergarten in Jinfeng District, Yinchuan City, Ningxia needs to achieve functions such as free grouping, broadcasting, and on-demand for each floor of the teaching building's classrooms, while also meeting the requirement that each floor of the listening exam can be individually multicast and played. To strengthen the later construction, the system needs to consider easy expansion and upgrading in the later stage. The system consists of 20 high-quality ceiling mounted components for indoor zoning, wall mounted speakers for classroom zoning, and 5 outdoor luxury sound columns for outdoor zoning. The system can achieve full coverage of campus classrooms, indoor and outdoor playback, paging speech, and other functions.

Project requirements:
The design of the public broadcasting system is mainly aimed at improving modern management, diversifying campus education, disseminating teaching information, and providing safe and stable listening system support for the school's examination system. The specific requirements are as follows:
Having both decentralized and centralized management modes, decentralized refers to setting up network audio terminals in each classroom of the school, which can enable independent broadcasting and control in each classroom; Centralized broadcasting refers to the establishment of system servers and sub control stations at the school's main broadcasting station. By utilizing the school network, various regional broadcasting audio terminals, network paging stations, and sub control software operating systems are connected to form a digital network broadcasting system for unified management< Br/> Equipped with functions such as manual broadcasting, scheduled broadcasting, temporary insertion, terminal configuration, terminal status viewing, terminal work monitoring, and program library establishment, as well as supporting external functions such as fire linkage broadcasting and wireless remote control broadcasting; The system supports terminal remote on-demand, paging terminal, and broadcasting functions< Br/> Campus education is diversified, and various self-made voice teaching audio courseware can also be uploaded to the server, automatically played on time or available for on-demand in the classroom, meeting the needs of modern school multimedia teaching. Teachers can submit scheduled playback tasks through workstation software, arrange voice playback plans and teaching materials for areas within their authority, and create a good learning atmosphere< Br/> The principal and director do not need to go to the computer room, but can publish broadcasting management information about the school in their own offices< Br/> School broadcasting should have the ability to achieve independent or group playback in different regions and multiple regions, which can be easily completed through software operation< Br/> School broadcasting should have functions such as timed task software programming, system server automatic operation, playing different programs at different time periods, program automatic playback, and automatic stop to meet the automatic operation requirements of the school's unmanned system< Br/> Listening system: The daily teaching listening system, as well as the requirements for the middle and high school entrance examination listening system.

System Introduction:
According to the usage requirements of the school's broadcasting system and the distribution of the school's buildings, the broadcasting system adopts an IP network broadcasting system based on campus network mode for transmission and control. The network broadcasting system solves the problem of large and wide areas in the school, making broadcasting transmission difficult. Through the transmission of campus network, the above problems are well solved and the audio quality of campus broadcasting is guaranteed. Stable and reliable network broadcasting directly depends on the network
