摘要
介绍了一种改进的火灾信号预处理方法——使用带通FIR滤波器进行采样信号的预处理工作,通过滤波器有效去除火灾信号中的干扰信号后,应用Matlab工具对该滤波处理方法进行了仿真分析。
It introduces an advanced method,which uses the band-pass FIR filter to realize pretreatment of sample signals.Comparing with high-pass FIR filter,this filter has better performance.After disturbing the single in fire is removed,the filter method is simulated with Matlab.
