Abstract
Accurate acquisition of vibration signal information is the key for bearing fault diagnosis. This system comprised a sensor to obtain vibration signal data
which are transmitted to STM32 micro-controller after A/D conversion
STM32 controls Wi-Fi module to transfer these data to PC. Afterwards
Local mean decomposition(LMD) is adopted to analyze and process the vibration data to perform a remote monitoring on the running state of the rolling bearing. The experimental results show that the system is capable of collecting and analyzing vibration signals effectively of the rolling bearing
it has good transmission performance at a fast speed and can be introduced to the industry.
