Abstract

The invention provides an adaptive variable range motor vibration detection device, comprising a vibration detection module, a signal preprocessing module and a control module. The vibration detectionmodule is composed of a vibration sensor and used for detecting and acquiring vibration information of a motor to be detected. The signal preprocessing module is used for preprocessing the acquired vibration information of the motor to be detected and transmitting the vibration information to the control module. An input end of the signal preprocessing module is connected with the vibration detection module, and an output end of the signal preprocessing module is connected with the control module; The control module comprises a controller, a power on/off control circuit and a multipath analogswitch and is used for matching analysis with the range of the vibration sensor according to the vibration information of the motor to be detected so as to complete online adaptive conversion of therange of the vibration detection module. The adaptive variable range motor vibration detection device of the invention can solve the problems of poor adaptability and low detection accuracy caused bythe use of a fixed-range motor vibration detection device and the inability to convert the range online in the prior art.

Description

technical field [0001] The invention relates to the field of motor equipment, in particular to an adaptive variable-range motor vibration detection device. Background technique [0002] During the operation of the motor, due to mechanical reasons such as installation and electromagnetic reasons such as the application of the driver, the motor will vibrate during operation. By detecting the vibration information generated during the operation of the motor, the working state of the motor can be known during operation. On the one hand, it can cooperate with the motor control strategy to reduce the vibration generated by the motor during operation to a certain extent, thereby reducing the damage to the motor and prolonging the service life of the motor; The controller sends out a shutdown signal and an alarm to avoid damage to the motor. [0003] At present, in the related art, the vibration detection of the motor equipment adopts the vibration detection equipment whose measure...
