Compared with traditional buildings, intelligent buildings in the new era have introduced many advanced technologies, including network technology and communication technology, and effectively combined with traditional building technologies to form an integrated control system, which is beneficial for intelligent buildings to complete their work requirements according to technical requirements.
1 Overview of weak current system integration in intelligent buildings
1. 1 concept
According to the definition of intelligent building in GB/T503 14-200, it is mainly based on architecture and is a system integration, including building equipment, communication network system and office automation. It can effectively combine building management and service to provide safer, more convenient and more comfortable buildings for human beings.
1.2 Main functions of intelligent building system integration
The main task of the whole intelligent building system is to assemble multiple systems. Because the intelligent building system introduces advanced internet technology and communication technology, it can ensure the normal communication between systems and effectively control all the information in the whole system. The core system of intelligent building system is weak current integrated system, which can create a good environment for the information transmission of the whole system. In addition, there is a key system: building system, which integrates all the systems in the whole intelligent building into a large system, namely building system integration. In this process, we must rely on the assistance of network system and automation system, recombine the functions and information of the system, apply internet technology to the whole intelligent building system, effectively realize the integration of all systems, which is conducive to the proper management of building information.
1.3 Significance of weak current system integration in intelligent building system
The realization of intelligent building system integration must rely on internet technology and management technology, and the core technology of intelligent building is the rapid collection and effective management of system information. The premise of information integration is to ensure the integration of weak current systems, provide a unified and complete information management platform for building systems, and effectively control each subsystem. In intelligent buildings, weak current system has many application advantages, including strong practicability and mature technology. By combining all the functions of the building system, the comprehensive building management system can be improved and the information release and sharing of the building system can be better realized.
2 Design objectives and principles
In the new era, with the rapid development of information technology, the system integration of computer networks has become the mainstream direction of development. From the development trend, product functions and software systems are integrated, which can better adapt to the development of information technology in the new era and provide economical and convenient solutions for users of intelligent buildings. The weak current system of intelligent building belongs to computer application system, and the development of integration is the only way. The level of integration is also an important indicator to measure the degree of intelligent building, and it is the key to evaluation and grading after the completion of intelligent building construction. China has clearly stipulated that "intelligent building is not a simple collection of various products", and the core technical method to realize intelligent building is system integration.
3 integration of weak current system in intelligent building
3. 1 data integration
Intelligent buildings generally need to use databases, and the network system is regarded as an important auxiliary tool for information communication and exchange among subsystems in the whole intelligent building system. At present, with the rapid development of science and technology, great progress has been made in network technology and information technology, the degree of integration of information systems has been significantly improved, and its requirements for intelligent building databases have been gradually improved. Intelligent building must be equipped with C/S client to better realize data monitoring, and the information in each data monitoring host can be transmitted to the server, which then packages and transmits the data to the server. After the data processing library is established, data transmission can be completed in a short time.
3.2 Network system integration
At present, network information technology is developing well. With the development of network technology, the construction rate of intelligent buildings is getting higher and higher. Internet technology has been widely used in intelligent buildings. Through the automatic control platform between buildings, the smoothness of information transmission between buildings can be improved. It is worth noting that if the hardware equipment used in the intelligent building network system is poor, all systems can be effectively connected when the advanced network information system is introduced. It is convenient to build a network information system, but it still needs to provide data information for each subsystem. Information management can realize the enjoyment of resources more efficiently.
3.3 Gateway Integration
Gateway is very important in intelligent building management system. The gateway function can effectively reduce the system burden and protect the system. In order to realize the integration of gateways, it is necessary to connect and integrate with third-party devices. After the integration of network management, each subsystem can be effectively controlled, and the network management can also coordinate the connection of each subsystem. Therefore, the realization process of gateway integration is very critical.
3.4 steps of system integration
System integration usually needs to follow the following steps: (1) Effectively manage the functions of each subsystem, ensure that it meets the basic service requirements of the building, and monitor the operation of each subsystem equipment in real time. If faults are found in the process of monitoring, corresponding measures must be taken to pay close attention to maintenance and make a maintenance plan. (2) The integration of building automation system and fire alarm system, building automation system and security monitoring system. (3) Integrate all subsystems of the whole building and adopt a unified computer management platform and TCP/IP standard protocol. By connecting the intelligent interface and the data gateway, the subsystems are interconnected. Through Ethernet and data gateway, the data exchange of the central integrated management system is realized. Data gateway is an important client of central integrated management system. Through the client, data can be sent to the server in two forms: instant and scheduled. The integrated framework of intelligent building system is shown in figure 1.
4 prospects for the integration of weak current systems in intelligent buildings
At present, compared with developed countries, the research on weak current system integration in intelligent buildings in China is not deep enough. However, with the continuous development of science and technology, the network will play a more prominent role in the integration of weak current systems in intelligent buildings, the importance of the network will gradually become prominent, and the intelligent ability of weak current system integration will become more prominent. The structure of weak current system of intelligent building should be based on each subsystem and strengthen the development of technical performance. In the future, the centralized control of weak current system must rely on advanced network technology and computer technology, and its integrated realization focuses on the application of cyberspace and the expansion of resources. In addition, there will be more and more smart products in the future, which will help promote the integration of weak current systems. Therefore, more attention should be paid to the timeliness of service content and network when developing the integration method of weak current system.
5 conclusion
To sum up, the integration of weak current systems in intelligent buildings mainly depends on advanced network technology and communication technology, and the key to integration lies in resource sharing. In the future development of intelligent buildings, we should devote ourselves to how to improve the timeliness of network information. For the research of weak current system integration mode, we must actively invest a lot of technology and funds to improve the intelligence of system management, and combine the integration mode with network technology. The specific implementation method lies in the development of network client and the application of remote operation technology in this system.
