Design of pipeline displacement detecting system based on MEMS accelerometer

To solve the problem of safety of the gravity-dropped slurry pipeline in the complex terrain,a design of pipeline displacement detection system based on MEMS accelerometer and the combination of the microcontroller and wireless communication is proposed.The system is mainly composed of chip STC89C52RC,solar-powered module,the displacement data-collecting module,wireless data transceiving modules,and data storage and display module,and the displacement data is sent through the serial port to the PC to display as the basis of judging the operating security by the pipeline control room.Experiments show that when the pipeline displacement reaches the threshold,it can effectively alarm.At the same time,the system is simple and stable and can effectively predict the displacement of the pipeline.
