Development And Research On The Security Precaution System Based On Fieldbus

The development of the intelligentized building has produced not only the intelligent mansion but also the intelligent district. 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 intelligentized district control system is paid close attention to.Combined with practical system,the computer control system based on intelligentized district of the Fieldbus has been discussed mainly in this paper. The structure of the security precaution system and equipment monitoring system has been debated in detail in the thesis,and the main relevant technology has been studied carefully.Chapter one introduced the research background of the thesis,sketch basic structure and basic characteristic of the computer control system. Chapter two introduces the control object of the system,which is the intelligent district;and analyzes the reason that the intelligentization thought has been put forward and basic composition in the intelligentized district. Chapter three has carried on the present hot Fieldbus technology in detail;and analyzed the structure characteristic of Fieldbus technology,several kinds of bus technology at present have been compared with each other. Chapter four has introduced LonWorks technology at length. As the industrial standard of the domestic intelligent-building field,LonWorks is extensively applied in the intelligentized district. The article has done detailed research to Neuron chip,LonTalk communication protocol,network variables etc. Chapter five has introduced the main technology of the intelligent district computer system. The serial ports of communication technology,communication program development,and multithread programming technology has been analyzed in detail. Chapter six analyzed the structure of equipment monitoring system,and recommend monitoring software model and the method of data gathering procedure. Chapter seven develops the course of security precaution system in the intelligentizeddistrict,including the system demand analysis,the system structure design,and the database structure design. In addition,some difficult questions in the course of software development have been probed. Chapter eight has discussed the developing direction of the intelligent district computer system and prospect of Fieldbus technology.With the development of people's living standard,the intelligentized district would be paid more attention to by the society;the computer control system must get more extensive application during district construction.
