With the continuous improvement of the intelligent requirements of modern buildings, the building automation system, as an important part of the intelligent building, is of great significance for improving the management efficiency and energy utilization efficiency of the building. Architecture choices are particularly critical when implementing building automation systems. This paper will make a detailed analysis of the application of BS architecture in building automation system, aiming to provide useful reference for relevant practitioners.
The BS architecture, i.e., browser and server architecture, is a web-based application architecture. In this architecture, the client application is simplified and contains only a web browser, while the main functions of the application are implemented on the server. The user accesses the web page on the server through the browser and interacts with the server, realizing the information sharing and data interaction between the client and the server.
Application advantages of the B S architecture in the building automation system
1. Reduce costs: The client part of the BS architecture only needs a standard web browser and does not need to install specific software, thus reducing the maintenance cost of client hardware and software.
2. Cross-platform: Web browser has a wide range of platform compatibility, and BS architecture applications can run on different operating systems and devices, which improves the scalability and flexibility of the system.
3. Easy to upgrade and maintain: The upgrade and maintenance of the server-side application of the BS architecture is relatively simple, and only the server-side needs to be updated to achieve synchronous updates of all clients.
4. High security: The data transmission of the B S architecture adopts encryption technology to improve the security of data transmission. At the same time, because the data is stored centrally on the server, it is also convenient for unified security management and backup.
Implementation of the BS architecture in a building automation system
1. System architecture design.
The building automation system based on the BS architecture mainly includes three levels: data acquisition layer, data processing layer and data display layer. The data acquisition layer is responsible for collecting the operation data of various equipment in the building; The data processing layer is responsible for processing, analyzing, and storing the collected data; The data display layer is responsible for displaying the processed data to the user in the form of graphics, **, etc., and receiving the user's control instructions.
2. Data acquisition layer implementation.
The data acquisition layer mainly collects the operation data of building equipment through various sensors and intelligent devices. These sensors and smart devices are distributed in various areas of the building according to the needs of the system and communicate with the data processing layer to transmit the collected data to a server. In order to ensure the accuracy and real-time performance of data, sensors and smart devices with stable and reliable accuracy should be selected.
3. Data processing layer implementation.
The data processing layer is the core part of the entire system, which is responsible for processing, analyzing, and storing the collected data. In the BS architecture, the data processing layer is mainly implemented on the server side. The server uses efficient data processing algorithms and an optimized database management system to process and store the received data. At the same time, the server is also responsible for the control and regulation of various equipment to meet the operational needs of the building. In order to ensure the stability and reliability of the system, high-performance server hardware and reliable operating system should be selected.
4. Implementation of data display layer.
The data display layer is mainly responsible for displaying the processed data to the user in the form of graphics, **, etc., and receiving the user's control instructions. In the BS architecture, the data presentation layer is implemented through a web browser. Users can access the web page on the server through a browser to view the operating status of building equipment, energy consumption data and other information, and can remotely control the equipment through the control buttons on the page. To improve user experience and ease of use, a clean, easy-to-use interface should be designed. At the same time, the front-end framework and web technology with fast response speed and strong interaction should be used to improve the real-time and user experience of the system.
