Intelligent fire alarm system based on technology of CAN fieldbus

Thisp paper proposes an intelligent fire alarm and control system based on CAN fieldbus technology and multi single chip computer communication system. controller area network(CAN) is a fast serial bus that is designed to provide an efficient, reliable and economical link between sensors and actuator. CAN uses a twisted pair cable to communicate at speeds up to 1Mbit/s with up to 40 devices. Miss alarm and error alarm are two difficult problems in fire alarm system. By use of the new technology of CAN fieldbus and single chip computer technology, the system proposed in this paper provides some new intelligent method to solve these problems. The alarm veracity and system reliability are improved by the use of these new methd and technology. This system also provides great convenience to the design of engineering and construction.
