Study on optical fiber grating sensing technology applied in temperature measurement of mined-out areas

摘要：

In this paper,an advanced mining fiber fire monitoring system is proposed,which meets the need of coal industry and mined-out areas.The system adopts the international advanced fiber grating temperature-sensing technology including Fiber Grating temperature sensor and demodulation.Compared with the conventional electrical sensor,the optical fiber sensor has more advantages.Such as: not charged,essential security,small volume,light weight,simple structure,anti-electromagnetism,easy to realize multipoint distributed measurement,etc.In summary,this technology can realize real-time long-term monitoring to the mined-out areas.
