Railway vibration monitoring system based on ARM and acceleration

With the quick development of computer, microelectronics technique and network technique, the acceleration sensor has been widely applied. This design is to check and analyze the railway vibration. Moreover, the theory is based on the relation of acceleration and vibration. The ARM-V7 structure STM32103ZET6 is used to drive ADXL345. The microprocessor reads 3 axes acceleration values of XYZ from the accelerator sensor, and sends out digital signals and the angels with nature coordinate to the host in order to control and analysis. The host receives the acceleration and angles successfully through the tests. We research the noise processing in the acceleration signals and the threshold setting of the program facilitating to judging fault of the railway vibration.
