1. System requirements 
In order to meet the needs of modern teaching and management mode, our school plans to gradually establish a school-wide teaching network system, which uses multimedia technology and distance education technology, integrating digital, video, audio and other media in one, throughout management and teaching In all aspects, improve work efficiency and provide an informatized teaching environment for school teachers and students to conduct teaching, management, and scientific research activities. The specific requirements are as follows:
Establish a closed-circuit television interactive multimedia integrated teaching system. The system realizes: the principal's TV speech, temporary TV monitoring, shared media resources throughout the school, two-way multimedia teaching, and control and management of the school's teaching TV.
2. The necessity of system construction On the basis of the unidirectional campus CCTV system, it is converted into a CCTV interactive multimedia system, which is the real TV teaching system. Teachers can actively control the computers, video recorders, DVD players, etc. of the main control room remotely in the classroom. A variety of media playback devices significantly improve the quality of teaching and classroom effects, enhance students ’interest in learning, and change the teaching model so that teachers can easily use the equipment. At the same time, school equipment is managed in the main control room, and the main control computer controls the TVs in each classroom Control, easy for various management of audio-visual teachers.
3. System design features Multi-channel program source switching In the Lucent SD series of closed-circuit television interactive multimedia integrated teaching system, the universal remote control has 4 sets of program switching functions. During the same teaching time, teachers can perform simple operation program switching on 4 channels of programs.
No changes to equipment
In the closed-circuit television interactive multimedia comprehensive teaching system, the control system adopts full infrared remote control technology, and all equipment does not need any modification.
Mouse control
In the SD-D8000 closed-circuit television interactive multimedia integrated teaching system, the remote controller of each classroom is equipped with a universal remote controller with a mouse trackball, which can control the operation of the remote computer at any time in the classroom, and use hot keys or shortcut keys to timely Go online and switch between various program sources.
Unified power management and temporary monitoring
In the SD-D6000 and SD-D8000 closed-circuit TV interactive multimedia integrated teaching system, the main control room can detect the normal conditions of classroom equipment, control the classroom TV power supply, channels, return the real picture of the classroom TV, and temporarily monitor a classroom Open class.
Intelligent Directional Broadcast
The main control system of the interactive multimedia system has the function of wired intelligent broadcasting or wireless FM broadcasting. When the wired intelligent broadcasting system needs to be installed, an audio cable is added to the wiring system, the classroom is connected to active speakers, and the main control room is connected to the power amplifier. Selective intelligent campus broadcasting can be carried out; when automatic FM broadcasting needs to be installed, there is no need for separate wiring. The main control room can be connected to an FM transmitter and broadcast automatic playback host, and the classroom can be connected to an FM speaker to realize multi-channel FM broadcasting.
Break through tradition
The use of traditional teaching equipment is to move video recorders, DVD players, computers, etc. to the classroom for teaching, which is inconvenient and easy to damage the equipment. In order to make up for the above deficiencies, our company specially launched the "Lixun SD series-CCTV interactive multimedia integrated teaching system ". The system is a high-tech teaching system with perfect performance and simple operation. It is an indispensable tool for schools to carry out audio-visual teaching.
High intelligence
The system takes advantage of the characteristics of a computer, and delegates the processing of a large amount of control information to the "central intelligent controller", which simplifies the wiring and hardware equipment of the system, has greater reliability and functions, and has higher efficiency and more convenient networking with campus . And a good computer control interface makes the operation easier.
High capacity
The basic capacity is 128 terminals and 16 program sources. If necessary, it can be expanded to 256 terminals and 64 channels of program sources.
Bus
All control signals and intercoms are completed by only one twisted pair from beginning to end, which not only reduces the cost, but also increases the reliability of the system.
Convenient and fast networking function
Through computer networking, the Luxeon SD series can be connected to the Internet and other types of networks through the remote keyboard and mouse in the classroom to roam online, achieving a good transition from the CCTV teaching system to the campus network system.
Upgrade function
The design of the system fully takes into account the modernization of education and the rapid development of teaching equipment. Each system has an interface platform that can be expanded and upgraded, which can be upgraded very conveniently. The company can continuously provide the school with the latest technical support.
4. System design principles Principle of practicality
No matter how much the project investment is, it can fully play its role in the actual classroom teaching and management, to achieve high frequency of use, improve work and classroom efficiency, is the primary design principle.
Principle of convenience
The system is based on simple operation and simple principles to meet the needs of teachers in various subjects.
Stability principle
Under the premise of frequent use of the system, ensure the normal operation of the system to ensure the smooth progress of classroom teaching.
Compatibility principle
According to the actual situation of the school, every system should be compatible as much as possible, and various resources should be used as much as possible to become an inseparable whole.
Principle of scalability
The system is scalable and can be compatible with other new systems at any time.
Economic principle
Make the system easy to use and enough, choose equipment according to the current situation of the school, ensure the rationality of the investment, and choose the performance-price ratio suitable for the specific situation.
