分布式光纤光栅测振技术在核电安防中的应用研究

The Application of Distributed Fiber-Grating Technology on the Vibration Detection in the Security and Protection System of Nuclear Power Plant

针对厂区振动光纤探测系统受大风影响频繁产生误报警、定位精度低、环境适应能力差等问题,提出采用分布式光纤光栅入侵报警系统作为替代方案,通过实践应用表明该系统具有布置灵活、精度高、误报警率低、维护方便等诸多优势,具有应用推广价值。

In order to solve the problems concerning vibrating-fiber detection system such as false alarm, low positioning precision and poor environmental adaptability caused by strong wind, this paper puts forward a distributed optic fiber-grating technology as an alternative scheme. The practical application shows that the new system exhibits more advantages in respect to flexible arrangement, high precision, low false alarm rate, and maintenance convenience etc., and is worth for widespread application.
