Queen's Park Bridge ambient vibration data with multiple setups

Three datasets, TS01, TS02 and TS03. TS01 has 7 triaxial servo acc. 30 min. @ 200Hz for 1 setup, covering 6 locations on one side of bridge and 1 location on the other side, total 7x3=21 dofs. TS02 has 6 (2 reference + 4 rovers) triaxial servo acc. 15 min. @ 200Hz for 16 setups, covering 33 locations each on 2 sides of bridge, total 33x2=66 locations and 66x3=198 dofs. TS03 has 4 MEMS acc. from smartphones for 10 min., covering 4 locations on one side of bridge, total 4x3=12 dofs. The data at different smartphones was started at about the same time but with different sampling rates.本数据集涵盖TS01、TS02与TS03三个子数据集。TS01配置7台三轴伺服加速度传感器（triaxial servo accelerometer），单组布设场景下采样时长为30分钟，采样率200Hz，测点覆盖桥梁单侧6个位置与另一侧1个位置，总计7×3=21个自由度（degrees of freedom，DOFs）。TS02配备6台三轴伺服加速度传感器（其中2台为参考传感器、4台为流动测点传感器），共开展16组布设场景，单场景采样时长15分钟、采样率200Hz；测点覆盖桥梁两侧各33个位置，总计66个测点，对应66×3=198个自由度。TS03采用4台智能手机内置的MEMS加速度计（MEMS accelerometer），采样时长10分钟，测点覆盖桥梁单侧4个位置，总计4×3=12个自由度；不同智能手机的采样启动时刻大致同步，但各自采样率存在差异。
