There are 2 buildings and 5 floors in the teaching building, with a corridor length of 120 meters and a total of 98 classrooms;
The administrative building has 6 floors and a corridor length of 100 meters, with a total of 30 offices;
The 2 dormitory buildings have 5 floors and the corridor is 100 meters long;
A canteen has 2 floors. 3,000 square meters per floor;
An outdoor standard sports ground; outdoor trunk roads and green belts on campus.
At present, the school plans to establish a digital campus daily broadcasting, teaching broadcasting and background music system. Requirements are as follows:
Adopt IP network broadcast system, use existing LAN and realize multi-network integration. Full digital transmission, covering the entire campus.
The system has good scalability. As long as the campus network can cover the broadcast information point, all networked computers in the campus network can be used as the branch control point of the campus broadcast system; such as the teacher's office, the student office, and the leadership office. Each broadcast control station is set up.
It is required to use a computer to operate the broadcasting system, to meet the basic needs of regularly playing the music ringtones of the classes, the inter-class broadcast exercises, eye exercises, daily broadcast notices, etc., and to realize the unattended campus digital automatic broadcast function.
The campus broadcasting system can be set up through the software to achieve unified centralized system control management throughout the school, and there are independent control management in each area, which can meet flexible zoning and grouping without the need for additional wiring. The broadcast administrator can flexibly change the classroom grouping settings according to the actual situation; the teaching building can implement a point-to-point broadcast system; the classroom can be assigned programs at the same time by grade or class, or English listening training and exams.
The teaching building, administrative building, cafeteria and dormitory on the campus can be divided into several fixed partitions, and all buildings can be arbitrarily combined or controlled in the broadcast center. You can listen to the same source program at the same time, or broadcast separately.
Campus broadcasting requires monitoring. System administrators and authorized leaders can monitor or monitor the content of any broadcast point on campus in real time.
The campus broadcasting system also needs to be able to meet school broadcasts (such as: issuing administrative notices, leadership speeches, etc.), emergency fire broadcasting, campus background music, English listening learning, broadcasting radio stations, playing music and music appreciation, etc., so as to cultivate students' interest and create good Campus Environment.
Second, the system plan design combines the user's needs, with the best design plan to reflect the highest performance-price ratio, so that the system's functions and indicators reach the advanced level of the same type of system in China.
Overall System Construction Goals At present, the overall goal of campus information construction is to build a campus information broadcasting system with information sharing, resource integration, centralized management, and good service based on the principles of first-class planning, first-class design, first-class construction, and first-class quality. The construction of Jinmai Video Campus Digital IP Network Broadcasting System is based on the requirements of school users, using modern computer software engineering, TCP / IP network, automatic control, voice codec and other information technologies to promote the integration of multiple networks and establish multi-level, Innovative and open model schools, guided by new teaching concepts and management theories, go beyond the traditional education model and improve the quality and efficiency of comprehensive schools.
With the advancement of modern education construction today, modern buildings are rapidly developing towards large-scale and comprehensive directions, so that the management of broadcast audio systems has become more and more complicated, and the requirements for system functions and reliability are becoming higher and higher. Mainly based on large campus bells, radio and various campus background music playback functions, depending on the actual venue, using a variety of different speakers can cover the entire teaching function area and campus sound field.
System design description This design makes full use of the existing campus network, or pre-frames the basic campus network system to reduce repeated wiring and construction projects, which is simple and fast. Realize the campus broadcast system to meet the daily management, timing, real-time playback requirements, less equipment, simple maintenance; friendly interface and easy operation. The daily teaching broadcast and listening learning effect is good, effectively improving the learning effect. Make sure the sound is clear and smooth in the English listening test.
The division of broadcasting is reasonable. The network broadcasting terminals of each district can speak to the broadcasting point in this area, or can perform two-way paging and intercom with the broadcasting main control room, leading workstation, and broadcasting terminals in other areas. For example, the dormitory administrator can broadcast the affairs, notify, call people, etc. of the dormitory he manages through the broadcast terminal installed in the management room.
The leading office installs the network paging terminal GM-8003. You can select any terminal for individual traffic notification, and select a terminal with intercom function for two-way intercom to achieve more convenient internal communication. Teachers can publish management information to the classrooms they manage in the office;
Like other standard network equipment, campus network communication can be used. Workstations on teachers' and leaders' notebooks can work in any area covered by the campus network to facilitate teachers' office needs.
The main control workstation (main control center) of this campus broadcast is designed in the teaching building. Broadcast control: The main control room is located in the broadcast monitoring and control center on the first floor of the teaching building, which can realize any point-to-point single-point control. The corridors and outdoor areas such as teaching buildings, administrative buildings, dormitory buildings, canteens, etc. are divided into several areas, so that single points, groups or all broadcast points can be selected for broadcasting.
This system is designed to forcibly insert the emergency broadcast of fire protection and public emergencies into this broadcast system. The system design network alarm host adopts a networked interface, which can expand the number of fire routes at will; sixteen fire signal input, fire signal network transmission, and alarms are set at any point ;,
System front-end audio source design Campus audio system audio source includes digital audio source and analog audio source. Mainly use computer (system server host), high-quality DVD player, touch double deck, digital tuner, broadcast microphone, wireless microphone, etc.
