[China Instrument Network Instrument R&D] On the morning of October 19th, the National High-tech Research and Development Center of the Ministry of Science and Technology organized the national high-tech research and development program undertaken by Changfei Optical Fiber & Cable Co., Ltd. (hereinafter referred to as “Changfeiâ€) (below The abbreviation "863 Plan") - "Development and Application of Advanced Fiber Optic Sensor System" was subject to on-site review and acceptance. Senior Director Liu Jinchang of the Advanced Manufacturing Department of the National High Technology Research and Development Center of the Ministry of Science and Technology and the expert group heard reports on the implementation of Changfei Company's projects, reviewed related materials, and conducted on-site inspections. After questioning and discussion, the acceptance expert group unanimously believed that the project completed the research content specified in the mission statement, achieved the objectives of the project, met the requirements of the technical indicators of the project, and the acceptance expert group recommended acceptance of the technology.
The topic of “Development and Application of Advanced Fiber Optic Sensor Systems†was formally established in January 2012. The project was completed in December 2015 with an implementation period of 4 years. The project leader is the deputy director of the State Key Laboratory of Optical Fiber Cable Manufacturing Technology of Changfei Corporation. Dr., the participating units include Wuhan ChangYangTong Optoelectronic Technology Co., Ltd., South China University of Technology, Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, Wuhan University of Technology, Wuhan Polytechnic Optical Co., Ltd. This topic develops advanced sensor core components such as high-precision pressure sensors, time-grating displacement sensors, fiber optic sensors, industrial scanning probe microscopic test systems, aerospace digital manufacturing-oriented cross-scale precision measurement systems, and cross-scale in-situ mechanical testing instruments. The system meets the needs of high-end equipment manufacturing and industrial instrumentation for accurate measurement of basic physical quantities such as position, pressure, temperature, and topography. It has formed a demonstration application and industrialization capability, and has met the huge domestic market demand for sensor products.
This topic independently developed new types of characteristic optical fibers and key devices for advanced optical fiber sensors, which effectively improved the performance index and measurement accuracy of the sensing system. The four-level symmetry of the bridge fiber was proposed by using a curing glue and a skeleton that matched the temperature stress of the optical fiber. Winding method and low tension winding process, winding the fiber ring, suppressing the shoop effect of the fiber ring, improving the temperature stability and accuracy of the fiber ring; developing a single-frequency laser as a sensor light source, improving the sensing performance from the source A high-performance distributed fiber temperature and strain sensing system was constructed to realize the on-line monitoring and demonstration application of power cables.
Through the implementation of this project, Changfei Company has realized polarization-maintaining fiber, photonic crystal fiber and rare earth-doped fiber products and special fiber integration technology, developed a distributed fiber temperature strain sensor system prototype, a series of new fiber optic sensor parts, and developed High-speed high-precision demodulation instrument and state intelligence analysis system, mechanical equipment operating state intelligent perception cloud service platform prototype system, to achieve a multi-parameter distributed temperature, pressure, stress strain, acceleration, displacement and other parameters of the operation of large-scale complex mechanical equipment Online Monitoring.
