Some problems in the design of intelligent weak current system

Abstract: intelligent building is the combination of traditional building technology and modern information technology. As human society enters the information age, setting up intelligent systems in buildings has gradually become an important part of building functions, and the content of intelligent systems is also increasing. With the vigorous development of the real estate industry in China, intellectualization, as a new development hotspot, has also promoted its development to a certain extent. But at present, the implementation of intelligent building is not standardized, and there are still many problems in the design and implementation

As human society enters the information age, the setting of intelligent systems in buildings has gradually become an important part of building functions, and the content of intelligent systems is also increasing. With the vigorous development of the real estate industry in China, intellectualization, as a new development trend, is the hot spot of activity-based costing, which also promotes its development to a certain extent. But at present, the implementation of intelligent building is not standardized, and there are still many problems in the design and implementation. Design is the forerunner and soul of the construction of intelligent weak current system. As the design unit of the main building, the design institute has certain advantages in undertaking the design of intelligent system. On the one hand, it depends on the gradual standardization of the integrated market of intelligent system design. At the same time, it also depends on the designers' ability to adapt to the market demand, master new technologies, and improve the design ability of intelligent buildings

Zhejiang Architectural Design Institute, Zhejiang University Architectural Design Institute, China United Engineering Corporation, Hangzhou Architectural Design Institute, Wenzhou Architectural Design Institute and other units have made certain efforts in this regard, and have undertaken the intelligent system design of a large number of large-scale projects by enriching and adjusting their forces, The author also participated in the intelligent system design of large public buildings such as Hangzhou National Tax building, Ningbo national inspection University composite aircraft building, Anji county administrative center, Zhejiang Mobile hub building, Zhejiang University Science and Technology Park, Dongyang people's court, Yueqing power building, and intends to discuss some common problems in the design

I. characteristics and charging of intelligent weak current system design

intelligent weak current system has many contents, fast technology updates, and no mature and fixed mode to follow; Although the national standards "intelligent building design standard" and "national residential district intelligent system demonstration project construction key points and technical guidelines" have been issued, they are all recommended standards. In practical application, different regions will differ with the local technical and economic development. Designers mainly design according to industry standards and specifications in specific design; The owner's personnel are mostly the original civil engineering professionals, who lack in-depth understanding of the weak current system and are unable to provide a clear demand analysis; As the overall design of the project, the civil engineering design unit was originally convenient for professional coordination and cooperation, which was very beneficial to the design and implementation quality of the project, but most civil engineering design units excluded the weak current system from the design scope due to qualification problems and unclear design costs

with regard to the charging of design, in the 2002 revision of the charging standard for engineering survey and design issued by the Ministry of construction of the State Development Planning Commission, weak current has been charged as a single discipline, according to the charging base price in the basic price table of engineering design corresponding to the investment, and a complex adjustment coefficient of 1.3 can be considered. According to the estimated weak current of 10million, the charging rate can reach 5%

II. Definition of design content and scope

the design depth of intelligent weak current system has not been clearly stipulated by the state and industry. At present, it is mainly divided into scheme design, expansion design, construction drawing design and deepening construction drawing design with reference to the requirements of strong current design. The scheme design and expansion design are mainly to analyze and refine the needs of the owner. The main workload of the weak current system design is that the weak current construction drawing design is basically synchronized with the civil design, and the specific equipment model has not been determined. After the later interior decoration design is completed, the setting of the weak current front end point often changes. Therefore, the weak current construction drawing design should mainly determine the content and overall scale of the whole system, the roughly reasonable front-end point layout, the basic structure and mutual relationship of each subsystem, the coordination requirements with other disciplines (the signal contacts reserved in the strong current distribution box, the power configuration of information points), the location of main machine rooms and weak current rooms, satellite antennas and UPS loads

weak current construction drawing design shall mainly provide the following drawings: general description of design, list of main materials and equipment, general layout, weak current plan of each floor (according to the complexity of weak current system, it can be divided into 1~2 sets of plane representation: 1 set of BA system engineering, 1 set of other weak electronic systems, meeting system plan), overall system structure diagram, subsystem system diagram, BA system control point table, BA system control schematic diagram, and various details (satellite antenna location and installation details, layout plan of equipment in each weak current machine room, layout details of weak current room), UPS distribution system diagram of weak current system, overall point position table of system front end, lightning protection and grounding system diagram of weak current system, etc

III. design of generic cabling system

as the main carrier of modern communication and computer network system and the information highway in the building, generic cabling system is the communication platform of the whole building intelligent system, and has become an important part of the building intelligent system. In theory, generic cabling design can support the wiring of various intelligent subsystems, but it is essentially the most suitable for the wiring of voice and data

1. determination of the number of information points

with the improvement of the building's demand for local and wide area applications, there are more and more generic cabling information points in the building. The "intelligent building design standard" stipulates three standards a, B and C, of which the class a standard is one double hole information point per 5~10m2 work area (one supporting voice and one supporting data), The code for engineering design of generic cabling system in buildings and building clusters is divided into integrated configuration. Basic configuration and enhanced configuration. After estimating that they are also applicable to the area of the injection molding machine area (usually about 1/3 of the building area), we can quickly estimate the area of the building
