In order to improve the accuracy of pipeline leakage monitoring in various complex situations,data fusion analysis technology is applied to the design of pipeline leakage monitoring system.In terms of hardware,based on the characteristics of pipeline trans-portation,pressure sensors and temperature sensors are used to design system hardware monitoring nodes.In terms of software,it sets the format of pipeline monitoring data forwarding frames and data correctness verification codes to achieve system data trans-mission;It fusions pipeline leakage data collected by different sensors,calculates the average,mean square and variance of pipe-line monitoring data,analyzes pipeline leakage data from the perspective of time domain,judges whether there is leakage in the pipeline,and realizes pipeline leakage monitoring.The experimental results indicate that the designed pipeline leakage monitor-ing system can obtain accurate pipeline leakage monitoring and warning.
