Design Ideas for Intelligent Upgrade and Reform of Campus Broadcasting
In strict accordance with the design specifications (excerpts) of the fire alarm system of the Ministry of Public Security of the People's Republic of China (GB50116-98) as the design basis, combined with your needs, the best design solution is used to reflect the highest performance-price ratio, so that the system functions and indicators reach The advance of domestic similar systems is our overall design idea. It is embodied in the following aspects:
2.1 Advancedness and scalability: With the development of modern information technology, new products and new technologies emerge endlessly. Therefore, the system should make full use of the latest modern technology when the investment cost permits, so that the system can adapt to social development in the longest possible time. However, due to the rapid development of modern science and technology, the future development needs must be fully considered, and the design scheme must be forward-looking and scalable. This scalability not only fully protects Party A's investment, but also has a high comprehensive performance-price ratio. This design has given full consideration to this, the necessary pipelines are embedded, and various interfaces are reserved, which is extremely convenient for system expansion and upgrade.
2.2 Science and Standardity: The campus broadcasting system is different from the general sound system. It is an advanced and complex comprehensive system project. It must start from the system design, including the entire process of construction, installation, commissioning, and final acceptance. Standards and specifications, and do a good job of systematic standardized design and scientific management. Finally, a formal test and acceptance report and a full set of construction drawings and technical data are submitted for Party A's archives. Especially as a government funding project, it is necessary to ensure that the entire project can withstand rigorous tests in various aspects and for a long time.
2.3 Security and reliability: The construction of campus broadcasting system directly affects the user's use effect, external image and return on investment. Therefore, the system design must be safe and reliable. This solution has fully considered the use of mature technologies and products. Type and system design to minimize the occurrence of failures. And from the aspects of line laying, equipment installation, system debugging, and technical training of Party A personnel, all of them must meet the reliability requirements. A particularly important point is that all major key equipment selected for this scheme, and promised to give full support in the provision of engineering equipment, technical support and after-sales service.
2.4 Sound quality optimization: The core of the design is sound quality. In order to achieve this goal, the selection of equipment is the primary condition. We choose high-fidelity products here, and cooperate with advanced and reasonable system design to ensure the optimization of sound quality.
III. Selection Principles for Intelligent Upgrade and Reform of Campus Broadcasting
3.1 Scientificity, accuracy and advancedness of system design:
When designing the campus broadcasting system, ensure that the acoustic technical indicators of these venues meet the requirements specified in the bidding documents, so that the sound system design of each venue is scientific, accurate and advanced.
3.2 Systematic and practical to meet functional requirements:
In the campus broadcast system equipment configuration, we ensure that the system should have the ability and level to complete the functions required by the project, meet the actual needs of the project and the requirements of relevant domestic regulations, and are easy to implement and easy to operate.
The equipment used in the campus broadcast system are all advanced products from well-known domestic and foreign manufacturers. The equipment's indicators meet the requirements, and they have consistency and interchangeability, which makes the system have good flexibility, compatibility, scalability and portability.
3.3 Equipment reliability and service guarantee:
The main equipment in the campus broadcasting system we designed are products of famous brands. XXX professional products have extremely high reliability and outstanding performance and have been successfully applied in various places in the country. Users enjoy a 1-year free warranty, and have established comprehensive technical service networks throughout the country to provide customers with timely and effective services.
3.4 economy of system configuration:
We always follow the principle that the ratio of the performance and price of the equipment used in the campus broadcast system is optimal to ensure that the campus broadcast system configuration is highly economical and practical.
Functions and Applications of Intelligent Upgrade and Transformation of Campus Broadcasting
After the system is upgraded, it can integrate school broadcasting, background music, work and rest signals, multi-zone power control and other functions into one. While completing school and other work and rest signals with music (or music ringtones), it can also engage Listening to English can also enable students to appreciate the beautiful songs and tunes, cultivate their sentiments, and create a good campus environment. Its main functions are as follows:
4.1 Replace Chinese and foreign electronic ringtones with famous Chinese and foreign songs (or music ringtones);
4.2 Regularly play eye exercises, radio gymnastics, and campus background music;
4.3 Automatically retransmit radio programs and tape programs on a regular basis;
4.4 Automatic or manual directed regional broadcasting: noon music, school music broadcast to the whole school, etc .;
4.5 Fully automatic system operation: In the morning, the system automatically controls the content of daily work and rest. After all the daily work and rest are finished, it will automatically exit and stop.
4.6 Seven sets of programs can be set in a week (it can be different every day). Hundreds of daily work items can be set each day. The length of each piece of music can be set arbitrarily, from one second to the whole song, from one song to dozens of songs. The need for playback control;
4.7 The outdoor sound column and indoor broadcasting box used in the system are designed according to the characteristics of the school and produced by Hite Wai Yip. Its appearance and sound quality are better than those of general market products .
