The Design And Implementation Of Intelligent Building Based On Lonworks And .NET Technique

AS a core of intelligent building 3S (Building Automation System, Communication Automation System and Office Automation System, the three basic elements of intelligent building), the performance of BAS is the foundation stone of high effective running of an entire mansion weak electricity system. The control network technique adopted in BAS directly affects that Whether the different equipments inside mansion can work harmoniously with each other and practice thrift the energy to the utmost, And effects that whether mansion proprietors can run the building by fewer administers and reducing the operation cost as much as possible. LonWorks technique is a new generation technique of control network developed by Echelon. It supplies a complete set of control system settlement scheme. As an open flexible system , It becomes the best choice of Building Automatic System.On the other hand, Internet has become an inseparable part of people life while it becomes popularization all over the world. People are getting more and more used to linking up reciprocally and performing business affairs by utilizing Internet. The intelligent building theory researches also go into .NET age at the same time. The swift development of internet technique and application in Building Automation System cause that mansion administration staff do not come out the door and may complete the monitoring Real-time control and proper protection to the entire building . At the same time,by means of internet, the authorized user may obtain the required data through the mansion everywhere. They may also supervise the entire BAS in a distance place. This shall combine intelligent building and internet, Moreover make intelligent building become significant node in internet.Based on the above technique backdrop, Home and abroad intelligent building actuality together with tendency were formerly analyzed. This paper also Analyses the current problems exist in this territory, Moreover we propose that it is necessary to introduce Lonworks technique into China to help achieve it's leaping over style development in the intelligent building territory.Subsequently, we research and analyze the principium, Composition setup and correlation distinguishing feature of Lonworks technique. By discussing about the key problems related to control network and information network, We propose how to combine Lonworks with .NET on the network layer, Thereby achieve intelligent building control system.Finally, we designed an intelligent systematic total frame for a building in detail, and reach the aim of design an intelligent building by combine Lonworks with . NET technique, Moreover expatiate the process of design and realization.
