摘要
基于迈克尔逊干涉原理和弹簧有机结合, 自行设计出一种新型的测力传感器装置。采用线阵CCD作为光电传感器件捕捉干涉圆环的光强信号, 并通过MSP430单片机对电信号进行处理, 再利用设计出的迈克尔逊干涉圆环计数软件自动计算出干涉圆环数目, 即可自动精确计算出弹簧的形变量, 从而实现对所受的外力进行测量。编写相应的程序将力的大小由低功耗OCM126864-9液晶屏显示。分析表明, 该测力装置具有高测量精度和高智能化的特点。
Abstract
A new force transducer is designed based on Michelson interference principle and springs. Liner array CCD is used as electro-optic sensors to capture the light intensity signal of interference circles and the electric signal is processed by MSP430 SCM. The designed counting software of Michelson interference circles are used to figure out the number of interference circle automatically. The deformation of springs can be calculated automatically and precisely to realize all external forces measurement. The force can be displayed on low-power OCM126864-9 LCD screen by writing corresponding program. Analysis shows that the force transducer has the features of high measurement accuracy and intelligence.
