1. The broadcast center adopts an embedded operating system, pure hardware, digital equipment and partitions. The Educational Affairs Office and the Political Education Office set up call stations to facilitate teaching announcements and speeches. Classrooms and function rooms can be broadcast by point-to-point single call through the system. Outdoors and corridors are first digitally partitioned and then broadcast by the corresponding power amplifier.
2. The teaching building is required to integrate the multimedia system and the broadcasting system. The classroom digital broadcasting terminal also has all the functions of modern network control (including remote control of projectors, computers, whiteboards, booths, classroom air conditioning, etc.). Status monitoring, projector switch delay protection, lamp usage time recording, and remote locking of the entire multimedia system). For the safety of students and teachers, the equipment and power supply should be minimized around the desk. The digital broadcasting terminal requires a built-in 60W + 60W digital intelligent power amplifier system for the common use of multimedia systems and digital broadcasting systems. The computer operates the broadcast system and classroom multimedia equipment, and authorizes multiple paging broadcast points. Use the existing computer campus network, do not lay too many wires to browse, increase digital broadcasting, and realize unified and centralized system control management throughout the school. You can freely choose music as the ringtone for the class, and automatically play the class exercises and background music regularly. English listening training and examinations are conducted simultaneously in grades or classes in the classroom. The system has strong expandability and realizes an unattended digital campus.
Third, the overall broadcast is reflected in: digitalization --- the new embedded ARM9 high-speed CPU, LIUNX operating system kernel, can easily achieve various functions; integration --- highly integrated equipment, teaching platform and campus broadcasting are combined into one More economic value; Networking --- Make full use of network resources to realize digital campus broadcasting and remote control multimedia teaching platform. In the campus local area network, real-time remote control and broadcast can be performed on the same network segment and across network segments to achieve fast and reliable information communication.
4. All broadcast receiving points can be grouped arbitrarily, and groups can be combined freely. Through the software for point-to-point and point-to-group broadcasting, the volume of each zone (point) is freely adjusted by the total control room.
Fifth, play regularly, under the setting of the background control software, multiple sets of work time are programmed 24 hours a day, first arrange the content to be played (such as class bell, class bell), after the play time, the software will automatically be in accordance with the regulations Play within the time, the time is accurate to the second.
6. Manual broadcast. When temporary playback is needed at some time, the administrator can stop and insert the broadcast at any time on the background computer. One click to suspend or resume all daily broadcasts of the school, providing convenience for school exams or other applications.

With USB mobile broadcaster, plug in the place where there is a computer in the campus network and immediately notify or shout the equipment of the whole school (under the premise of installing the corresponding broadcast player software), and can achieve the mixing mode, one Key switch (FI-F12 arbitrarily set and name the shortcut keys of each area) to set the area to broadcast, or shout to increase the mobility of the equipment. U-disk hardware design, easy to carry, supports USB interface, simple plug and play operation. USB-KEY has various permissions to set the permissions of the areas under the jurisdiction of leaders at all levels (such as the first-year director, only the permissions are for the first-grade classes to speak or play audio content).
Nine, without having to be in the main control room, teachers can submit scheduled playback tasks on any networked computer through workstation software, arrange voice playback plans for classrooms within the scope of authority, and create a good learning atmosphere. Self-made audio teaching courseware can also be uploaded to the server for on-demand in class and teaching evaluation function.
10. Description: The product has passed 3C, ISO9001, ISO14001 certification
