Fiber grating sensing and fiber communication integrated system

The invention discloses a fiber grating sensing and fiber communication integrated system. Communication and detection integrated applications are performed on the same fiber network, so the quantity and the weight of fibers are reduced. During fiber arrangement, the fiber layout process complexity and the assembling time are reduced, the system reliability is improved, and the equipment cost is cut. If sensor network communication is separated from other platform buses, the bus communication reliability is improved. Once buses malfunction or other faults occur, a sensor network can still be used normally. Therefore, a more reliable basis is provided for detection workers to detect, analyze and handle platform faults.
