摘要
为有效预测电气火灾的发生趋势,减少人们生命和财产损失,提出一种基于SoPC系统和CAN总线的电气火灾预警系统方案,该系统利用SoPC技术减小了火灾报警系统监控节点的设计复杂程度,同时结合现场总线通信距离远,抗干扰能力强,实时性好的优点,有效地保证了该系统的预警监测范围。与传统的火灾报警系统相比,该系统的主要优点有2个,一是该系统侧重对电气火灾的预测与预报,在火灾发生之前报警以减小损失;二是每个监控节点都带有高性能嵌入式软核处理器,使单个节点具备火灾预测信息处理的功能,大大增加了对电气火灾预测的准确率,同时减少了上位计算机的负担。
To predict the trend of electrical fires and reduce the loss of people＇s lives and property,the electric fire warning system project based on SoPC and CAN Bus is introduced.This system used the technology of SoPC to reduce the complexity of designation,combined with the long distance communication,strong anti-interference and good real-time performance of field bus,the range of monitor is effectively guaranteed.Compared with the traditional fire alarm device,this system has two main superiorities： one is that this system is emphasis on prediction electric fire,and it is designed to warn in front of fire hazard to greatly reduce the loss,the other is that each monitor node contains a high performance embedded soft core,which can process the relative information.This system can greatly improve the accuracy of fire prediction,while relieve the road of host computer.
