Study And Design On The System Of Intelligent Community Based On LonWorks Technology

Intelligent Residential Community (IRC) has become a new industy with the development of Imformation Technology (IT), which is in the primitive stage in our country at present.In this thesis, the author first discusses the concept and composition of IRC, 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 IRC and brings forward a designing scheme of IRC based on lonworks. In this scheme, The whole IRC is taken as a lon network, and each user terminal as a node of lon network, which has some intelligent functions, such as alarm information autodetecting, telephone auto-dialing and voice-calling, remote auto-measurement of watt-hour meter, water meter and gas meter,as well as the control of electromagnetism door. After the designing of nodes, the author organizes the whole lon network and the monitoring-and-managing software of Realestate Management Center.During the node designing of Lonworks control network, a new theory of double CPU was posed here, which has overcome the lack of single Neuron chip as the node by adding a non-Neuron chip which together with Neuron node which compose the double CPU mode.By applying the theory, Home-intelligent controller is successfully designed and developed, making the double CPU mode creative and practical.
