Portable linear motor multi-axis linkage measuring and controlling system

Abstract

The invention discloses a portable linear motor multi-axis linkage measuring and controlling system. The portable linear motor multi-axis linkage measuring and controlling system comprises a computer, a multi-axis motion control card, a grating, a current sensor, a voltage sensor, a signal processing circuit and a wireless transmitting and receiving module. Positions, speeds, voltage, currents and other performance parameters of all axis linear motors are collected dynamically, the grating, the current sensor and the voltage sensor send collected signals to the motion control card through the wireless transmitting and receiving unit, the multi-axis motion control card communicates with the computer through the wireless transmitting and receiving module, data are displayed through an own liquid crystal display screen of the control card, or the multi-axis motion control card is connected with the computer in a wireless mode, and the collected data are displayed, analyzed and stored through a virtual instrument development platform LABVIEW. The portable linear motor multi-axis linkage measuring and controlling system has the advantages of being simple, portable and high in sampling speed, testing accuracy and processing efficiency and avoiding complex wiring.

Description

technical field [0001] The invention relates to the field of motor automatic testing, in particular to a portable linear motor multi-axis linkage measurement and control system. Background technique [0002] With the increasing application of multi-axis processing machine tools such as XY table driven by linear motors, five-axis machining centers, and turn-milling machine tools, multi-axis motion control technology suitable for high-speed and high-precision machining of complex shapes and surfaces has become more and more popular. people's attention. In the testing or control process of linear motors, the control and monitoring of some parameters such as position and power are crucial, which are directly related to the precision performance of the motor. [0003] The existing linear motor multi-axis linkage measurement and control system needs to transmit the measured value of the online signal provided by each sensor to the computer through the corresponding cable. It als...
