TLJ型土工离心机数据采集系统更新升级
Update and upgrade of data acquisition system for TLJ geotechnical centrifuge
摘要
Abstract
The TLJ-3 geotechnical centrifuge from Chang'an University has been in operation for 18 years since it was built and put into use in 2004,making it the longest running geotechnical centrifuge in this series.Due to the low integration of electronic devices at the beginning of the 21st century,the early data acquisition systems of TLJ centrifuge gradually could not meet the high-precision and large data throughput collection needs of the existing experimental data.Based on the wireless transmission technology,the problem of data transmission caused by changes in contact resistance of electric slip rings is eliminated.The fiber optic integration of multiple sensors is used to miniaturize the sensors,non-contact displacement field scanning is used to achieve full section monitoring of the ground surface,and the Open CV image stitching technology is used to solve the problem of image distortion.The upgraded TLJ-3 geotechnical centrifuge has served several research projects with good performance.关键词
