  • [2017-12]    睿科光电成功中标中国中车高速铁路铁轨监测项目

            Recently, our company has successfully won the bid for the distributed optical fiber demodulation instrument procurement project of CRRC Corporation Limited, this instrument will be used for the research and development of "Major Project on advanced rail transportation"---Rail Transport Security Technology Project, as parts of the 13th Five-Year plan borne by CRRC. In this project, Anshan Realphotonics Technology Co., Ltd., as a technical support organization, is responsible for providing the distributed optical fiber demodulation instrument for monitoring temperature and strain of the track, with design and implementation of the distributed optical fiber system for monitoring temperature and strain of high-speed railway track. In the competition of bidding and comparison with international famous distributed optical fiber demodulation instrument manufacturers, the testing contrast effectively highlight our product performance on high spatial resolution, accurate measuring precision, super long measuring distance and other advantages.
            This project is mainly applied to high-speed railway track temperature and strain monitoring. Due to the effect of the constraint of the sleeper, high-speed rail track will occur non-uniform deformation under the action of temperature fluctuations in the environment, and the deformation beyond the limits can cause significant security hidden danger of high-speed railway operation. In the region with the highest temperature difference during the year, the track may be caused by the effect of temperature load, such as rail expansion and distortion. Traditionally, to eliminate this potential safety problems, railway staffs need to check the temperature and deformation of the track, and in the region of high temperature differences or severe inhomogeneous deformation area of the track, they need to carry out stress relief operation for the track. This way of artificial troubleshooting and maintenance not only consume large amounts of manpower cost, inefficient, but the information of the rail state cannot be feedback timely, comprehensively, and it is difficult to cover a long range of railway lines.
            Distributed optical fiber sensing technology is the one of the best sensing technology to develop high-speed railway track temperature and strain monitoring system, four prominent advantages listed: first, the sensing distance is long, which can reach more than dozens of kilometers of the sensing distance; Second, sensing optical fiber is optical signal demodulation, anti-electromagnetic interference, and will not affect the existing electrical signal propagation in the track; Third, the fiber material is non-metallic, anti-corrosion, has excellent durability, can meet the requirements of track long-term monitoring; Fourth, the sensing optical fiber is small in volume, light in weight and good in deformation. It can be conveniently arranged without affecting the normal use of the rails.

  • [2017-12]    中国电子科技集团第二十三研究所光纤水听器监测仪项目顺利验收

            Recently, the project of fiber hydrophone monitor undertaken from the 23th research institute of China Electronic Technology Corporation has been completed and passed the check successfully. In this project, our company develops the first distributed Brillouin optical fiber sensing demodulator, realizing distributed strain and temperature measurement of the sensing arm of optical fiber hydrophone based on Michelson interferometer with 2cm spatial resolution. The results of spot test demonstrate the status of strain distribution and periodic strain distribution of optical fiber clearly. This demodulator reveals the structure of optical fiber hydrophone and meets the requirement of higher precision. Users give this equipment sufficient praises and a high appraisal.
            Optic fiber hydrophone is a kind of acoustic sensor working undersea based on optical fiber and optoelectronic technique. It has advantage of high sensitivity, great frequency response, anti-electromagnetic interference, long-distance transmission, and large-scale networking. It has been applied to monitor of ocean environment and earthquake tsunami. However, after a long term operation undersea, part of fiber loop inside will stand too much pressure due to erosion of hydraulic pressure, resulting in transmission loss and deterioration. Meanwhile, the optic fiber hydrophone maybe present different performance under different working conditions, such as different sea area and different depth. This phenomenon is related to craftsmanship, glue of fiber loop, and it limits the development of optical fiber hydrophone. In traditional Brillouin Optical Time Domain Analysis (BOTDA) system, because of the reflection of continuous light by interface of two Faraday mirrors, the intensity of interference signal of two reflecting light will be stranger than BOTDA signal, becoming jamming signal and being unable to measure distributed strain and temperature. Besides, the spatial resolution of BOTDA system is only ~1m, which cannot meet requirement of cm level.
            For this special requirement, we develop a differential pulse pair Brillouin Optical Time Domain Analysis (DPP-BOTDA) system, which can avoid the jamming signal effectively and overcome this difficulty. Meanwhile, it breaks the limitation of 1m spatial resolution and realizes 2cm ultra-high spatial resolution. It can be competent for distributed measurement of optical fiber hydrophone. This technique provides a new kind of test method for theoretical study of optical fiber hydrophone.
