Can Bus Technology, Research And Practice, The Intelligent Community Of The Underlying Network

In order to construct low-priced, reliable intelligent network in the uptown, to meet the demands of safety and information management in the intelligent uptown, I studied the fieldbus technology and one of its solutions ?CAN technology. Base on our country condition of intelligent building system and development tendency in the future, I made a suggestion on technical precept of CAN+RS485 double deck bottom network, to design a intelligent network model of uptown safety, field measurement and signal transmission.This model is base on CAN technology. The uptown CAN network is composed of Main controller (It has CAN bus interfaces) and cell controller. The lower layer of RS485 network is composed of many tenement signal collectors. The upper layer made use of PC to connect CAN network as management center in intelligent uptown, to realize the functions of management, control, alarm, signal collection and self-examination.This dissertation serves as an introduction to analysis, design, implementation and troubleshooting of intelligent network model. This dissertation is composed of intelligent uptown technology, feildbus technology, CAN technology, hardware and software.
