摘要
提出一种基于混沌理论的监测分布式光纤管道泄漏监测系统的方法,采用Duffing相轨迹法和Lyapu-nov指数法检测微弱的正弦信号,建立了基于混沌理论的分布式光纤管道泄漏检测系统的数学模型,并且进行了实例验证.
This put forward a method of monitoring distributed fiber-optic pipeline leak monitoring the system with cha- os theory. By using the method of Duffing phase trajectory and Lyapunov exponent to detect the weak sinusoidal signal, we establish a model of pipeline leakage detection system of distributed optical fiber based on chaos theory, and veri- fied by experiment.
