摘要
目的:设计一种基于单片机和计算机的心理测验数据实时采集系统。方法:系统由一个连接到计算机的单片机控制单元和多个与控制单元有线连接的手持键盒组成。低功耗的MSP430F135作为单片机控制单元的MCU,通过I/O口顺序扫描被试键盒的按键状态,实时采集被试对测验的反应数据,并通过USB接口将数据传送至计算机。结果:实验结果表明,系统通讯稳定可靠。经多家单位使用,该系统性能稳定,抗干扰性强。结论:计算机和电子技术的应用,实现了测验数据采集电子化,提高了心理学测验的效率,系统适用于心理学研究和检查。
Objective To develop a data acquisition system based on computer and micro control unit（MCU） for psychometric questionnaire test.Methods The system was composed of one MCU control unit connected with the computer and multiple hand-hold keypads wirely linked to the above unit.Low-power-consumption MCU MSP430F135 was used as MCU of the control unit.The status of the keypads were scanned by I/O of MCU,then reaction data of participants could be detected and sent to the computer through USB interface.Results The reliability,stability and interference immunity of the system were proved by the experiment.Conclusion The psychometric data acquisition system,with computer and electronic technology applied,can acquire electronic experiment data for psychological research and examination.
