Bearing Vibration Detection System Based on Eddy Current Sensor

In industrial production and life, it is often necessary to accurately measure the relative position among the instruments. Sliding bearings are key parts of many heavy machinery. And sliding bearing working conditions directly affect the safety of rotating machinery, thus stable and reliable operation is necessary. At the same time, mechanical vibration is common in the work of equipment, so the study of mechanical vibration has been one of the important issues in this field. In engineering practice, the mechanical vibration must be measured to observe the mechanical vibration and quantitative qualitative measurement. Therefore, it is necessary to study a set of sliding bearing vibration detection system, which is useful for equipment observation and theoretical practice research. This paper describes the bearing vibration sensor sliding bearing vibration detection system background, hardware design and software design part. The system uses ARM-based embedded microcontroller STM32F103 as the master chip, selects 50mm diameter probe JX20 bearing vibration sensor, uses dot matrix LCD screen LCD5110 real-time display of the measured results. According to the output of the bearing vibration sensor, the corresponding signal conditioning circuit is designed. Meanwhile, according to the system hardware design, the design of the corresponding software programs, including ADC sampling procedures and liquid crystal display program.
