Puniu Technology is a high-tech enterprise established for the transformation of industry-university-research technology at Shanghai Jiao Tong University. It was founded by the fiber optic sensing research team from the State Key Laboratory of Advanced Optical Communication Systems and Networks, and researchers with extensive experience in signal processing.
The company focuses on the research, design, manufacturing, and sales of high-precision distributed fiber optic acoustic sensing technology. Its products and solutions are widely used in various fields including oil and gas (leakage and safety warning for oil and gas pipelines, downhole condition monitoring for oil and gas wells, reservoir monitoring); transportation (rail wheel-rail and subgrade safety monitoring, tunnel noise monitoring, tunnel safety monitoring, highway subgrade condition monitoring); and civilian infrastructure (safety monitoring of urban pipe networks, airports, bridges, dams, municipal roads, high-rise buildings, etc.).
Since its establishment, the company has adhered to the principle of "technology research and development as the guide" and has collaborated with major universities and research institutes such as Shanghai Jiao Tong University, China University of Petroleum, SINOPEC Geophysical Research Institute, and the Innovation Academy for Precision Measurement Science and Technology of the Chinese Academy of Sciences. It has conducted a series of exploratory research projects including downhole acoustic monitoring for oil and gas wells, wheel-rail defect monitoring, natural earthquake monitoring, urban underground space exploration, long-term performance monitoring of highways, submarine cable monitoring, tsunami warning, cable partial discharge detection, microseismic monitoring, urban fault detection, coal mine safety monitoring, and urban lifeline safety engineering. Significant progress has been made in all these projects.
