Research on Hardware System of Monitoring Equipment for PHC Pile Construction
In order to solve the vibration monitoring problem generated during the construction of PHC piles,based on the background of the soft clay treatment project in the South Extension of Wanhuan West Road(Sixteen Chong Half to Haidi Section),the power module,MCU control module,acceleration acquisition module,and wireless module for vibration acceleration are designed and developed.STM32CubeMX and Keil5 MDK software from ST company are used to complete the PCB board,and hardware is made and applied to actual soft soft clay treatment projects,achieving vibration data collection,wireless transmission,and storage of the pile body,soil,and surrounding buildings during the construction of PHC piles.It turned out that the developed hardware system has the advantages of high-precision,easy integration,low cost,and wireless transmission.It can obtain a high signal-to-noise ratio vibration acceleration time history curve,providing rich information for evaluating the disturbance caused by construction.The developed equipment can be used for engineering construction vibration problems and structural vibration monitoring,and has broad application prospects.
