摘　　要：为实现集散式液位监测,设计了一种新型基于USB的光纤传感检测系统。系统利用强度补偿反射式光纤位移传感器和单片机完成多点液位信号的采集和数据处理,通过USB接口与PC机进行短距离高速数据通信,实现多处液位集中实时监测和超限报警。实验表明,本系统具有易于扩展、实时性强、精度高、本质安全等特点,有较高应用价值。To monitor distributed liquid-level, a new type fiber optics sensor system of liquid-level detecting based on USB is designed. In this system, a reflective fiber-optic displacement sensor with intensity compensation and a MCU are used for multipoint liquid-level signal acquisition and the data disposal. The USB interface is used for high-speed data communicating with PC in a short distance. The multipoint liquid-level can be monitored. It would give an alarm at the limitation highness. The results show that this system will be widely required in application for its characters of easily expanding, good real-time response, high precision and intrinsic safety.
