Abstract

The invention provides a wireless-based system and method for synchronously measuring the pressure along the way of a slurry conveying pipeline. The measuring system adopts wide-range and high-precision push plate type pressure sensors capable of preventing silt clogging, a pressure sensor is mounted on a dredging and sludge discharging pipeline at intervals, a solar panel is combined with lithiumbatteries to supply power for the measuring system, synchronization, transmission and storage functions of pressure sensor data are realized in a wireless mode, ship end data is transmitted to a dataprocessing terminal through wireless transmission equipment and is synchronized with the pressure data of the data processing terminal, a pressure change curve can be displayed in real time on a display screen of the data processing terminal, and the calculated value of the coefficient of friction resistance lambda m along the way of a measured pipe section can be given out according to the measured data. The system and the method provided by the invention can realize real-time, synchronous, long-term and stable monitoring and prediction of the change condition of the pressure along the way of the dredging and sludge discharging pipeline, and the technology of conveying of the dredging and sludge discharging pipeline for real-time and synchronous monitoring and analysis of the pressure along the way appears for the first time.

Description

technical field [0001] The invention relates to the technical field of pipeline slurry transport measurement, in particular to a wireless-based system and method for synchronously measuring pressure along a slurry transport pipeline. Background technique [0002] The environmental conditions of dredging construction are becoming more and more complex, and the construction difficulty is increasing, which puts forward higher requirements for the existing dredging equipment, technology and dredging and filling technology. Only when dredging enterprises continuously improve their overall strength, strive to improve the level of dredging technology and construction efficiency, strengthen construction management, and reduce construction energy consumption and construction costs, can they calmly cope with complex and changeable construction environmental conditions. [0003] At present, the mud discharge pipelines used by large dredging ships in sea reclamation projects generally h...
