A monitoring software of the host computer based on distributed optical fiber fire detection is designed

which can observe real-time temperature laying optical cable

and realize realtime alarming according to the temperature. The basic principles of distributed fiber optic sensing system

structure and optimization design of signal acquisition module of the distributed optical fiber sensing system are introduced

focusing on the PC monitoring software structure and function

and writing PC software with Qt. This system can monitor and accurately display the spatial temperature distribution of the fiber optic fiber

and has the characteristics of friendly interface

strong real-time and so on.
