Building Intelligent Design of the relevant discussions

Abstract Intelligent building in the intelligent system is a representative of the new science and technology, is to comply with the product of the times. When the intelligent building becomes a whole appearance, the intelligent system will be orderly and scientifically distributed in the application of the building to play its due function and role. Intelligent systems play an important role in intelligent buildings, in the management process, scientific management, comprehensive examination, effective arrangement, rational utilization. In order to achieve the best results, to ensure the safe construction of building projects. In this paper, we will comprehensively explain the design concepts of intelligent systems in intelligent buildings, as well as related issues that should be noted in the process of design and construction.

Keywords intelligent building; intelligent system; design

First, the design principles of building intelligent system

(a) advanced. Intelligent building intelligent system is with the development of information and electronic science and technology, therefore, in the design of the system should analyze the development of intelligent system, absorb the open advanced design concepts, in order to improve the functioning of intelligent buildings.

(ii) Reliability. In the intelligent system design should be used modular design concept, the intelligent system of the various subsystems isolated from each other to ensure that in some subsystem failures will not affect the normal operation of other subsystems or links, thus improving the reliability of the system operation.

(C) Standardization. With the rapid development of intelligent systems, the relevant system design standards have also been developed. In the system design should be in strict accordance with the system standard design, in order to facilitate the construction and maintenance of the system.

(d) Practicality. Intelligent system design should be able to fully realize the reception of cable TV, images, monitoring equipment, multimedia communications, security, voice, data and other functions, to ensure that it is perfect in the user's information communication and entertainment at the same time to improve the security of the user's environment.

(v) Economy. Intelligent system contains a number of internal subsystems, its subsystems contain a variety of components and equipment, so the system design process should be considered in the quality assurance while trying to save investment costs.

(F) scalability. In the rapid development of electronic information technology, the current intelligent system design content will appear a certain degree of constraints and limitations. Therefore, in the intelligent system design should consider the scalability of the design content, to ensure that the intelligent building can be updated and expanded under the future development of technology.

Second, the design of intelligent building systems

(a) power supply system design

Intelligent system subsystems are usually required to carry out a separate power supply, so you need to pay attention to the design of the power supply system. General computer network systems will use UPS for centralized power supply, in the uninterruptible power supply room power supply outlets also need to be centralized power supply, while the power supply into the line to meet certain capacity requirements can be; for the uninterruptible power supply is not used in the workstations, should also be used in a separate circuit for the power supply to avoid mixing of circuits to avoid endangering the operation of the system, such as the security system should be used in a separate circuit for the centralized power supply

(ii) grounding system design

The grounding of intelligent buildings will have a direct impact on the equipment and staff safety, system reliability and stability, the quality of information transmission. In the building grounding system design should be based on the function of the building and intelligent system requirements for the design, to ensure that it can be used in the application of parts of the response to the grounding end. It is necessary to install the electrostatic grounding system, auxiliary equipotential copper row, lightning protection grounding system, safety protection grounding system, work grounding system, DC grounding system and other parts. It includes two types of grounding:

1, joint grounding method, its application in the need to pay attention to: due to the computer and other equipment, lightning performance is not high, and its system contains ultra-large-scale integrated circuits can easily result in poor resistance to high-frequency interference, it is likely to be subjected to the interference of other systems, so it should be calculated using a separate way of grounding the DC power supply; in the use of joint grounding method of grounding resistance may be greater than 1? May be greater than 1?, so there are special requirements for intelligent subsystems should be used separately grounded.

2, a separate grounding method, in the use of unified grounding mainly using the natural grounding body, if no longer use the artificial grounding body should meet the following conditions: grounding resistance should be below 1?, that is, less than the specified value; building foundation of the internal reinforcement bars should be connected to each other to form an electrical pathway and closed loop, and the closed loop Ying should be with the ground to maintain the distance of 0.7m or more; the surface of the foundation of the building is not set up. Insulation waterproof layer. Due to the separate grounding method has the advantages of simple and convenient construction, reliable grounding, cost savings, etc., so in the intelligent building grounding system design has been more widely used.

(C) intelligent management room and intelligent shaft

Usually the computer network system for data communication lines have the necessary length and performance requirements, in the intelligent building intelligent system design, generally use copper twisted-pair cable as a horizontal line of the computer system, and copper twisted-pair cable will affect the bandwidth of the network transmission, so according to the wiring standards and specifications, should ensure that the network Switches and computers between the use of copper twisted-pair cable length within the range of 100m; according to the curvature of the pipeline and vertical conditions, intelligent management of the distance to the edge of the building should be in the range of 60m; in the network management should be placed in the corresponding network cabinets, which should be surrounded by the installation and maintenance of space to leave a reasonable plane should be in the range of 5 to 10m2.

(D) integrated wiring system design

In the integrated wiring system design, general voice cables or horizontal subsystem data cables should be used to support bandwidth of 100M Class D system and 5e UTP cable to meet the expansion requirements of a large number of users; the total length of the horizontal cable should be within the range of 100m, of which the optimal length of horizontal wiring cable is 90m. 90m, the length of the inter-telco wiring racks on the patch cords and junction cords should not be less than 5m, for the situation is not clear for the public **** space and its cable should be calculated in accordance with the following formula:

C=(102-H)/1.2 W=C-5

where H indicates the length of the horizontal cables; C indicates that the length of equipment cables, cables in the workspace with the inter-telco patch cords in aggregate; W indicates the maximum length of the workspace cable, the value should be below 22m; D indicates the total length of the equipment cable and inter-telco patch cords.

Third, the current intelligent building problems

(a) localized system integration products

Now occupies the domestic intelligent building market still belongs to a few foreign companies, such as the United States of America's Johnson Controls, IBM, Lucent Technologies and Honeywell. Domestic systems integration products do not have the initiative, which makes it difficult to make intelligent buildings completely and truly adapted to China's national conditions.

(ii) technical barriers

In the field of intelligent buildings throughout the still exist some technical deficiencies, such as network bandwidth limitations: rapid increase in the amount of data transmission and the use of multimedia, the requirements of a wide communication space; the use of antenna local area network also need to redistribute the valuable audio wave frequency law. With the introduction of new network technologies such as ATM, Frame-relay, etc., the problem of communication space can be partially solved, but the lack of a comprehensive and complete data model still prevents the effective exchange of data between various building automation and application systems. In addition, there is a tension between data security and seamless voice and data communications. Many organizations are concerned about the security of their internal information systems and the protection of their computers and voice systems from unauthorized access, but the isolation of a building to provide protection prevents the use of more advanced communications tools.

(C) the lack of talent

Talents engaged in intelligent buildings, including the design of specialized management personnel, security products, technical support engineers, wiring, security product development senior engineers, sales engineers (responsible for security, integrated wiring products, regional market sales), burglar alarm, monitoring products, large screen development senior engineers, software development engineers (mainly responsible for the building automation system software development). Building automation system software development), and the most in short supply is the intelligent building system design and management personnel. It needs to know the electronics, communications and construction of three aspects of specialized knowledge of the composite talent. Intelligent building projects, engineering design and construction are two aspects. And both understand the engineering design, but also understand the construction program is less and less. Design and construction of how to articulate and coherent good, related to the progress and quality of the project.

Intelligent building is a product of high technology, intelligent building discipline is a multidisciplinary cross and integration, personnel training should be multi-level, multi-faceted, only emphasize the close integration of theory and practice, design and technology, construction and products, in order to cultivate a new generation of intelligent building talent.

Fourth, the concluding remarks

Intelligent building design in the intelligent system is a high level of science and technology construction of difficult high-tech buildings, whether it is the planning of the intelligent system or its management, it is necessary to optimize the control, in order to achieve the optimal design of intelligent buildings. Intelligent system construction design quality will be directly related to the overall quality and service life of intelligent buildings. Therefore, the relevant research and designers should strengthen the comprehensive analysis and management of intelligent systems, summarize the experience and problems in the construction of intelligent systems, in order to continuously improve the level and quality of intelligent system construction design.
