The Data Processing System of Coal Slurry Pipeline Pressure Based on AMFL

Aiming at the problem of blocked pipe in coal slurry pipeline transportation process, the transportation experiment platform of coal slime pipeline is built for experiment and research. In order to analyze the pressure distribution and the blockage position of the pipeline, the data processing method was presented which combined average median filtering method and Lab VIEW-AMFL, the data acquisition system of coal slurry pipeline pressure was designed, include of the upper machine and lower machine. Here, the STC12C5A60S2 as the core of the system, collected coal slurry pipeline multiplex pressure data at different position, transmitted the data to the upper machine of Lab VIEW through the RS-232 serial communications, next, analyzed and displayed these data. And many experiments and tests were completed by simulating obstruction of different degree, achieved the multi-channel data acquisition system in Lab VIEW environment, the speed and accuracy of this method are higher than the traditional method.
