Button type linear vibration motor based on Internet of Things communication technology

Abstract

The invention discloses a button type linear vibration motor based on the Internet of Things communication technology, the button type linear vibration motor comprises a linear motor, an intelligent driving circuit, a magnetic base and a fixed base, the inner side of the magnetic base is insulated, the bottom of the shell of the linear motor is connected with the insulated side of the magnetic base, and the intelligent driving circuit is fixed on the magnetic base through the fixed base. Communication between an upper PC and a main single-chip microcomputer is achieved through an RS232 serial port, wireless communication of signals is completed through PTR8000, then the signals are transmitted to the single-chip microcomputer, resonance of a button type linear vibration motor is achieved through the intelligent driving circuit, and the tested industrial blade generates free vibration. According to the invention, the defects of different knocking strength and knocking directions and the like during the traditional industrial blade frequency manual hammer test are overcome, and the upper PC sends a resonant frequency signal to the linear vibration motor to generate consistent exciting force, so that the tested blade generates free vibration, and the measurement precision and efficiency are improved.

Description

technical field [0001] The present invention relates to the field of vibration motor industry, in particular to a button-type linear vibration motor based on the communication technology of the Internet of Things. Background technique [0002] As the Internet of Things technology matures, its applications in the field of Industrial Internet of Things are gradually increasing. In the traditional industrial blade frequency test site, the blade is knocked with a small hammer to make it vibrate. This traditional method will be limited by manpower, so that the strength of each knock and the direction of the knock are different, resulting in poor frequency measurement results. good. The linear motor has the characteristics of reciprocating linear operation in the direction of the vibration unit and the vibration is stable. Therefore, the linear vibration motor based on the communication technology of the Internet of Things has a promising application prospect in the field of indu...
