I. System design ideas and selection principles
(A) design ideas
(摘录)(GB50116-98)作为设计依据，结合贵方的需求，用最佳设计方案体现最高的性能价格比，使系统的功能和指标达到国内同类型系统的先进行列，是我们的总体设计思想。 In strict accordance with the design specifications of the fire alarm system of the Ministry of Public Security of the People's Republic of China (excerpt) (GB50116-98) as the design basis, combined with your needs, the best design solution reflects the highest performance-price ratio, so that the system's functions and indicators reach The advance of domestic similar systems is our overall design idea. It is embodied in the following aspects:
1. Advancement and scalability:
With the development of modern information technology, new products and new technologies are emerging 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. Scientific and normative:
The public broadcasting system is different from the general audio 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. It must be done in strict accordance with relevant national standards and specifications 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.
The main specifications of the implementation include:
①GBJ-89 "Engineering Technical Specifications for Cable Television System for Civil Buildings"
②GJ / T16-92 "Design Code for Civil Building Electrical Appliances"
③GB50168-92 "Code for Construction Acceptance of Cables for Electrical Installation Engineering"
④ GB50254-96 "Code for Construction and Acceptance of Low-Voltage Electrical Apparatus at the Bottom of Electrical Installation"
⑤JGJ / T16-92 "Code for Electrical Design of Civil Construction"
3. Safety and reliability:
The construction of the public 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, and tried its best in equipment selection and system design. Reduce 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. It is particularly important that all major key equipment selected in this solution have obtained the authorization certificate of the manufacturer or agent of the equipment, and promised to give full support in the provision of engineering equipment, technical support and after-sales service. (Pay the authorization certificate later) This is one of the key conditions for the key assessment of international and domestic engineering bidding projects.
4. Sound quality optimization:
Focus on 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.
/消防广播系统。 This design is based on Party A's requirements and comprehensively absorbs the advanced technology of the current domestic fire protection system, such as Hunan Huaihua Sports Center, Beijing Hualian Commercial Building, Shangri-La Hotel and Guangzhou Asian Games. Modern public / fire-fighting broadcasting system with elegant style, beautiful sound quality and complete functions . The main equipment is equipped with brand-name products to ensure superb performance indicators, while the auxiliary equipment is selected from imported or domestic reliable brands to appropriately reduce the cost. Utilizing our many years of theoretical and practical experience in system engineering design and construction, we carefully mix and match to ensure excellent performance and reliable quality.
(Two), selection principles
1. Scientific, accurate and advanced system design:
When designing the public 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.
2. Systematic and practical to meet functional requirements:
In the public 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 public broadcasting system are all advanced products from well-known foreign and domestic 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. Equipment reliability and service guarantee:
TEANMA(天玛)专业产品具有极高的可靠性和出色的性能表现已在国内各地成功应用并获很高的赞誉;同时TEANMA(天玛)专业产品在全国承诺所有用户享有2年的免费维修，3个月包换，并在国内各地建立有完善的技术服务网络，为客户提供及时有效的服务。 The main equipment in the public broadcasting system we design are products of well-known brands. TEANMA professional products have extremely high reliability and excellent performance and have been successfully applied throughout the country and received high praise; meanwhile, TEANMA (Tianma) (M) Professional products in the country promise that all users enjoy 2 years of free maintenance, 3 months replacement, and establish a comprehensive technical service network throughout the country to provide customers with timely and effective services.
4. Economics of system configuration:
We always follow the principle that the ratio of the performance and price of the equipment used in the public broadcast system is the best to ensure that the public broadcast system configuration is highly economical and practical.
Comprehensive Description of the Background Music System Design of Chencun Flower Culture Expo
1. Functional requirements of Chencun Flower Culture Expo:
① Normally play background music.
②The host interacts with the on-site visitors through the broadcast, releases some notices about the park and emergency notices, finds people on the live broadcast, etc.
2. Chencun Flower Culture Expo background music design plan:
The background music system of the Chencun Flower Cultural Expo is mainly used to provide daily background music and daily broadcast notifications for hotels, and it can further realize the function of controlling broadcast by area. Teanma广播系列中的数控广播系统，它良好的音质，简单方便的操作，集中功能，再加上该系统合理齐全简洁的配置，集我公司智能系统丰富经验，提出全套解决方案，使本工程完全达到投资者的要求。 According to the actual requirements and characteristics of Chencun Flower Cultural Expo, and considering the advanced, reliable and economical equipment, the main equipment is selected from the CNC broadcast system in the Teanma broadcast series. It has good sound quality, simple and convenient operation, and centralized functions Coupled with the reasonable and complete configuration of the system, the rich experience of intelligent systems of our company has been put forward, and a complete set of solutions has been proposed to make this project completely meet the requirements of investors.
The corresponding schemes are explained in detail below:
Broadcasting system analysis:
Since the background music of the Chencun Flower Cultural Expo is mainly distributed in the green belt of public areas and indoor corridors,
; Due to environmental considerations, so ;
(TM-626系列)。 The entire Flower Culture Expo uses outdoor weatherproof sound columns (TM-626 series).
