Research And Design On The Security System Of Intelligent Community Based On LonWorks

Intelligent Residential Community has become a new industry with the development of Information Technology, which is in the primitive stage in our country at present. The Security Precaution and the monitoring system of equipment are close and relevant with computer control system. With the development of the control system, especially the appearance of Fieldbus technology, the intelligent district control system is paid close attention to.Combined with practical system, in this thesis, the author first discusses the concept and composition of Intelligent Community, as well as its reality in our country and then introduce the main feature of Lonworks technology, finally, the author analyses the feasibility of applying Lonworks technology to Intelligent Community and brings forward a designing scheme of Intelligent Community based on Lonworks. In this scheme, The whole Intelligent Community is taken as a Lon network, and each subsystems as a node of Lon network. The structure and communication protocol of visual inter-conversation subsystems has been debated in the thesis, and the main relevant software development technology has been studied carefully.This thesis is organized into five chapters: Chapter One introduced the research background of the thesis, sketch basic structure of the Intelligent Community and Fieldbus. Chapter Two has introduced Lonworks technology at length. The article has done detailed research to Neuronchip, LonTalk communication protocol, network variables etc. Chapter Three brings forward a designing scheme of security system of Intelligent Community, and introduced each subsystems of security system. Chapter Four is the key chapter of this thesis. It introduced the structure and communication protocol of visual inter-conversation subsystems and designed the Circulation Converters. The main relevant software development technology has been studied carefully. At last, the main relevant software development technology has been studied carefully. Chapter Five concludes the thesis with a summary.With the development of people's living standard, the Intelligent Community would be paid more attention to by the society, the Lonworks technology and the computer control system must get more extensive application during the district construction.
