Research on Liquid Leakage Detection System Based on Embedded Technology
The liquid pipeline is susceptible to corrosion in the underground soil environment,which affects the service life and safety of the liquid pipelines,hence,this research uses multiple oil film detection sensors,oil level sensors,temperature sen-sors and other hardware devices to realize the performance detection of liquid pipelines.Hardware and software design for de-tection is based on embedded technology,including the central processing unit,memory,calculator,controller,A/D conver-sion module,D/A conversion module,and multiple sensor interfaces.The hardware design realizes the collection,calculation and detection of data information.The S3C6410(ARM11)is used as the processor of the microprocessor,and transmits data to the Linux kernel space in the embedded software through the serial peripheral interface(SPI)bus.The fault judgment of da-ta information is realized by Bernoulli equation.Experiments show that this study has the highest accuracy for liquid pipeline detection,with a docking accuracy of 99.2％,which improves the efficiency of detection.
