摘　　要：为了改善现有的超声电机数据采集系统不能处理大量数据、采集数据精度不高的现状,提出将MFC和多线程技术应用于超声电机数据采集系统。在Visual Studio 2012开发平台下,应用多线程技术的编程方法,设计对超声电机控制器实时收发数据以及串口监控的上位机软件程序,可实时测试超声电机在不同驱动电压和占空比的条件下转速和转矩与时间变化的关系。该软件可实现实时监测超声波电动机并对其进行操控的功能,已经成功地应用在实验室超声电机数据采集系统中。实践表明,该数据采集软件可有效控制电机启停,数据处理速度快、精度高,绘制曲线清晰、准确,可平稳可靠的运行。In order to improve the current situation that the existing ultrasonic motor data acquisition system cannot pro-cess large amounts of data and its data acquisition accuracy is not high,a method that the Microsoft Foundation Classes(MFC)and multithreading technology are applied to the data acquisition system of the ultrasonic motor is proposed. The programming method using the multi-threading technology on the Visual Studio 2012 development platform is emphatically introduced,and ap-plied to the design of the upper computer software program that performs real-time data transceiving and serial port monitoring for the ultrasonic motor controller,which can test the real-time variation of the ultrasonic motor′s rotating speed and torque ver-sus with time at different drive voltages and duty ratios. The software can realize real-time monitoring and operation functions of the ultrasonic motor,which has been successfully applied in the ultrasonic motor data acquisition system in the laboratory. The practical results show that the data acquisition software can effectively control the start and stop of the motor,has a fast speed and high accuracy in data processing,can draw clear and accurate curves,and run smoothly and reliably.
