Design Of Small Office Automation And Control Systems

With the booming of modern science and technology, building automation technologies are becoming more mature.At the same time, the requirement of the people for building automation system also will improve, more in pursuit of the automatic control system is secure, reliable and stable.In this article, the design of a compact five-story office building on the background of the automatic control system, by building new wind in the analysis, monitoring requirements lighting, low-voltage distribution, elevators and other systems, and gives the corresponding control scheme, its distributed control monitoring and ultimately make the system relatively better state of operation.Coupled with the internship experience in a unit of Xi’an before, and consider building its own characteristics, on the basis of the building automation system and also make a brief design on the meeting room control, through infrared remote operation to achieve the goal of control all the electrical and mechanical equipment in the meeting room.In the design of the building control system engineering, combined with design requirements of the building automation control system, and compare currently the three most popular of the major building automation products in the domestic,and eventually determine use the Siemens S7-200PLC automatic control system as the present design system platform.On the basis of this platform, we completed the design of the office building automation and control systems, including the selection of related hardware systems, electrical schematics, monitoring points table, in addition, the monitor screen completed by WINCC software, so as to achieve the goal of monitoring field devices.In order to improve the design of office building automatic control system, this paper deals with fresh air system in more detailed design, including the optimization of the new air volume control design, etc.Through the system installation and debugging, indicates that the building automation system is safe, reliable, advanced control scheme is reasonable, the overall performance has reached the expected goal. The design of building automation system provide a reference direction for building automation and related system.
