摘要
针对静冰压力检测的工程适用现状,设计了一种低功耗,全天侯自动检测系统.该系统基于反射式强度调制型光纤传感器,由光发射电路、光接收电路、AD转换电路、单片机电路以及数据存储电路等组成.对该光纤静冰压力的检测电路进行了实验测试,实验结果表明,检测系统电路可实现从作用于传感器压力敏感元件的微弱静冰压力变化到信号采集端的显著电压值变化及其自动检测.
According to current situation of static ice pressure measured, a full automatic test system is designed with low - power. This system is composed of laser emitting circuit, AD converter circuit, MSP430F1611 and data storage circuit. Experimental testing is done about this detection circuit of fiber optic static ice pressure. The experimental results show this circuit design can collect the variation of static ice pressure and achieve automatic detection.
