Large-scale fiber optic hydrophone array underwater acoustic detector development and application acceptance

[China Instrument Network Instrument R&D] On May 10, 2017, the preliminary acceptance of the project of "Development and Application of Large-scale Fiber-optic Hydrophone Array Underwater Acoustic Detector", a national major scientific instrument and equipment development, was held at Beijing Shenzhou Pratt & Whitney Technology Co., Ltd. The Wuhan Production and Research Base was held.

Li Jianling, a researcher at the Department of Conditional Finance of the Science and Technology Commission of Beijing Municipality, and leaders of relevant management departments such as the Beijing Scientific Instrument Equipment Collaboration Service Center attended the preliminary acceptance meeting. A total of 9 members of the acceptance meeting expert group were elected. The meeting elected the Academician Pan Deluo as the head of the expert group and presided over the meeting.

The “Development and Application of Large-scale Fiber-optic Hydrophone Array Underwater Acoustic Detector” project was led by Beijing China Puhui Technology Co., Ltd., the United Nations University of Science and Technology, Changfei Optical Fiber and Cable Co., Ltd., Harbin Engineering University, and Shandong Academy of Sciences Ocean Instrument Research Institute has completed the research and development of the instrument. The main application units include the Guangzhou Geological Survey, China Oilfield Services Co., Ltd. and Naval University of Engineering.

The development of large-scale fiber-optic hydrophone array underwater acoustic detectors completed four important breakthroughs: the development of a large-scale fiber optic hydrophone array acoustic echo detector with more than 1,000 detection primitives; and the formation of a batch of autonomous knowledge Property-based hydroacoustic devices; realized the innovative application and industrialization of large-scale fiber optic hydrophone array underwater sound detectors; and established a marine equipment production and research base.

The expert group reviewed the relevant materials, listened to the detailed report of the project and each mission unit, conducted an on-site inspection of the production and research base, and watched the demonstration of the instrument. The expert group questioned the project and each task to form expert opinions and agreed that the project of "Development and Application of Large-scale Fiber-optic Hydrophone Array Underwater Acoustic Detector", a national major scientific instrument and equipment development project, has initially met with engineering and industry. The capacity of the target has been sold to the target instrument, the research content specified in the mission book has been completed, the expected goal has been achieved, and unanimously agreed to pass the preliminary acceptance.
