Abstract

A pipeline network security warning system is designed based on vibration detection techniques, which consist of the front nodes module, relay modules and the computer monitor center in this paper. Someone dig in the ground of pipeline and destruction of the pipeline, when pipe stress change and the acceleration sensor close to the walls of the pipe feel the stress change. The signal through sampling transmit to ARM processor and after Wavelet denoising and the genetic algorithm processing and to have the true and false judgment by the relay modules to the information of the computer monitoring and control center with GSM module, and then PC monitoring software sound and light alarm and forwarding alarm information to the related personnel. At last the experiment shows the system could fulfill the objectives, that is, lower false alarm ratio and higher response ability.
