Wireless type flexible-arm vibration control system based on virtual instrument technology

Abstract

The invention discloses a wireless flexible arm vibration control system based on virtual instrument technology, which uses a SRWF-1021-50 wireless module for wireless communication. It consists of three parts: piezoelectric double-rod flexible arm, on-site vibration control terminal and main control terminal. Among them, AT89S52 single-chip microcomputer controls the movement of stepping motor, uses electromagnetic coil as sensor to detect vibration signal, piezoelectric element as actuator, and uses SRWF -1021-50 wireless module realizes the wireless transmission of signals between the vibration control terminal and the main control terminal. It solves the operation inconvenience caused by the use of wires, and at the same time improves the security of the system. The research on the wireless vibration control system has high practicability, and it is also of great significance to the realization of remote control and telemetry.

Description

technical field [0001] The invention relates to a wireless flexible arm vibration control system based on virtual instrument technology, which is suitable for the mechanical field. Background technique [0002] With the rapid development of modern science and technology and social economy, flexible arms are widely used in machining, precision measurement, aerospace and other fields due to their advantages of high work efficiency, low energy consumption, and large load-to-mass ratio. However, the flexible arm is prone to elastic vibration, which lasts for a long time, which makes it difficult to accurately position the flexible arm, reduces work efficiency, and affects the normal use of the machine. The current vibration control method generally uses motors and smart materials to simultaneously control the movement of the flexible arm. The application of smart materials is also a hot spot in the research of flexible arms in recent years. In these studies, smart materials are...

Problems solved by technology

[0003] However, the traditional vibration control system has complex circuits and cumbersome installation, which is not suitable for remote control

It generally adopts the wired method. In multi-point, multi-parameter, long-distance detection and control, there are many cables that need to be laid and arranged, which takes up a lot of time, manpower and material resources, and is very easy to cause human errors.

Once a problem occurs, it is also very difficult to find errors in complex cables
