The Research Of Intellect Fire Control Monitor System Based On Spread Spectrum

The monitoring program based on by comparing several different means of communication , Intelligent Fire Monitor and Control System based on the tecnology of spread-spectrum which is famous for its immunity is brought up,which is raised to make Fire System more convenient,more ecnomic and more anti-interference.The design of hardware system is selected Direct Sequence Spread-spectrum SC1128 chip as its core. Hardware realization is designed in dail,inluding the design of spread-spectrum carrier,surrounder circuit of SC1128 ,the design of data collection, the design of alarming, in/out circuit anology varible and switching value, data concentrator and so on. Fire alarm controlor is a main part which is based on power line Orthogonaldirect phase-shift keying(Quaternary phase-shift keying). The design of solfware mainly contains communication initialization, Carrier send, Carrier Receive and so on. Finally using the system View simulation software for power line DS-CDMA system and the system anti-jamming carried out simulation analysis.
