一种基于CAN总线的电气火灾监控系统的设计

In this paper, on the basis of analyzing the functions, requirements, and products characteristics，an advanced kind of electrical fire monitoring and control system based on AVR MCU is designed. Firstly, the system design of electrical fire monitoring and control system is introduced. It divides the system into three functional sections that are residual current instrument transformer, electrical fire detector and electrical fire monitoring and control device. And then, the presentation of performance indexes of instrument transformer is emphasized, as well as the hardware and software of detector and monitoring and control device. At last, the system reliability is analyzed, and practical methods of improving reliability are discussed from the aspects of both hardware and software.
