基于LabVIEW与DSP的电机调速系统在光声图像采集中应用

Motor Speed Control System Application in MedicalImage Acquisition Based on LabVIEW and DSP

针对生物医学光声成像系统图像采集过程中要求扫描电机带动扫描探头的转速稳定可调,而且满足于上位机系统的LabVIEW图像采集主程序的兼容和可植入性,结合LabVIEW串口通信功能和DSP在电机控制技术中的应用,设计了一种图像采集系统的电机控制方法,实现了电机转速的可调与稳定精确控制。

For the scanning speed of probe driven by motor is stable and adjustable in the photoacoustic imaging acquisition system,the motor control program is compatible which can be embedded in LabVIEW main image acquisition program,combined with LabVIEW serial communication function and application of DSP in the motor control technology,a kind of motor control method was designed in image acquisition system.The accurate and stable control of the motor was realized.
