At present, the distributed detection system based on Bragg grating as sensor has become a hot spot at home and abroad due to its high precision, good long-term stability and easy detection. In ordering to improve the grating multiplexing capacity in grating sensor array, this paper proposes a new distributed the weak reflected Bragg grating temperature sensing network. The system is mainly composed of light source module, photoelectric conversion module, data acquisition module and data processing module, which combine the wavelength division multiplexing (WDM) with optical timedomain reflectometer (OTDR). And it has achieved simultaneous online monitoring of weak gratings at various central wavelengths through its homemade tunable multiwavelength light source. Due to the principle of grating reflection, the detection cycle of the system is about 1s without energy accumulation, shorter than the traditional sensing system. Because of using the OTDR, it can break through the limitation of light scanning bandwidth, and its single-channel measurement can be up to kilometers. As above, the system has many advantages, such as good real-time performance, large capacity, short response time, being able to adapt to a variety of work environment, etc.
