The two AQSIQ scientific research projects undertaken by Jiangsu Metrology Institute passed the acceptance

[China Instrument Network Instrument R&D] On June 30, the Scientific Research Institute of the General Administration of Quality Supervision, Inspection and Quarantine, Jiangsu Province, was responsible for the development of a comprehensive digital thread measuring device, and the development of a calibration device for borehole borehole quality inspection system. 》The acceptance passed smoothly, further highlighting the scientific research capabilities of Jiangsu Measuring Institute.

Seven experts from the Southeast University, China Machine Productivity Promotion Center, Nanjing Metrology Supervision and Inspection Institute, Zhejiang Institute of Metrology and other units formed an acceptance committee. Wei Huaiqin, Deputy Director of the Provincial Bureau of Planning and Science and Technology Department presided over the acceptance meeting. Ma Yuming, Deputy Director of the Provincial Metrology Institute attended the meeting. Acceptance experts listened to the project work report, watched the live demonstration, and after questioning and discussion, they agreed that the submitted acceptance data was complete and met the requirements for the acceptance of science and technology projects, completed the objectives of the project task book, and agreed to pass the acceptance check.

The project “Development of Digital Thread Synthetic Measuring Device” studied the measurement principle of threading integrated parameters (action size) and on-line real-time measurement technology, developed a new type of general-purpose digital thread measuring device prototype, based on the measurement principle and experimental data, to study error separation and The source of measurement accuracy was traced, and a self-calibration method for the device was proposed and programmed.

The “Development of Calibrating Device for Bored Pile Boring Quality Inspection System” completed a calibrated device for borehole quality inspection system for bored piles, including calibration device for caliper, calibrating device for sediment slag, and calibration device for inclinometer. The components can meet the calibration and calibration requirements of the manufacturer and the testing unit of bored hole drilling hole quality inspection system, improve the construction quality inspection level, and promote the testing and calibration ability of the bored pile detection system in the region.
