Background
The intelligent monitoring and management platform of the mechanical equipment can predict and analyze the health state and potential faults of the mechanical equipment according to data generated in the mechanical manufacturing. The capacitance method is a hot spot for researching the vibration analysis field in recent years, and the principle is that the change of the distance between the metal surface layer of the measured object and the measuring electrode layer caused by vibration is converted into the change of capacitance voltage, and the vibration displacement value is measured by the voltage value, so that the capacitance method has the advantages of quick dynamic response, good temperature stability, large measuring range, high precision and the like. However, in vibration measurement of a pipe (rod) shaped object, due to bending of the metal surface of the pipe (rod), the traditional capacitance sensor on the cylindrical surface is difficult to fix, the planar electrode is not matched with the metal cambered surface to be measured, and the sensor readings in one or more vibration directions are inaccurate, so that the measurement accuracy is not high, and the disturbance rejection capability is poor. Therefore, a plurality of angle measurements (for example, a is a sensor and B is a measured object in fig. 3 and 3) are required, and when the next point measurement is replaced after a certain angle measurement, in order to ensure concentric rotation, conventionally, a rotation shaft is provided at the center of a sensor mounting housing, then one rotation is performed after one angle is not measured, and if the rotation is performed for a plurality of times, multipoint measurement is realized. The rotating shaft is arranged in the center of the sensor shell, so that the installation space of the sensor in the shell is sacrificed, and the rotating shaft penetrates through the shell, so that the sensor shell is abnormally large, and the larger installation space in the shell is obtained, so that structural redundancy is caused.
