Problems solved by technology
[0005] However, in the application environment of large-scale spacecraft platforms such as manned space stations, communication satellite platforms, large-scale space deployment mechanisms, and space solar power plants, if grating sensors and communication optical fibers are arranged separately, it will increase the cost, and also cause cumbersome layout work. Increased weight of the entire system

Embodiment Construction
[0030] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0031] According to the functional requirements of the integration of system sensing and communication, and taking into account the maintainability requirements in future use, the present invention provides an integrated system of fiber grating sensing and optical fiber communication. The communication between terminals and the grating sensing in the transmission network space will greatly reduce the cost of complex optical fiber layout and realize the ability to perceive the environment of the communication system.
[0032] Such as figure 1 As shown, the integrated system includes an optical fiber modem module 3 and N communication sensing channels, where N is an integer greater than or equal to 1, and its value is determined according to the requirements of communication and sensing.
[0033] Each communication sensing channel is based on the optical fi...

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.
Description
technical field [0001] The invention relates to the technical field of optical fiber communication and optical fiber sensing, in particular to an integrated system of optical fiber grating sensing and optical fiber communication. Background technique [0002] In recent years, with the continuous development of sensor technology and information technology, people have higher and higher requirements for information transmission. Traditional electrical communication lines have been difficult to meet people's requirements for communication bandwidth. Optical fibers have exceeded the scope of backbone network applications. Transmission to end users; and in special systems (such as spacecraft, surface ships, aircraft, supercomputers, etc.), optical fiber communication technology has been applied to equipment and sensors. [0003] With the development of information technology, more and more sensors are used in production and life, and surface ships, large aircraft, space vehicles,...
