Sensing Science and Engineering Centre (SEC) Vibration Data

Two structural columns host the sensors (named A3 and A8) and sensors are mounted on the ceiling slabs of every second floor, i.e. levels 3,5,7 and 9 for both columns.  Most locations measure three axes of acceleration, except for Level 3 Column A8 and Level 7 Column A8 which only measure x axis.

Two additional sites are instrumented, a footbridge leading out of the building and a site to monitor the vibration under a Transmission Electron Microscope (TEM).

The footbridge has a total of 8 axes simultaneously measured with addition to two Acoustic Emmisions (AE) sensors monitoring the bridge support and mid span.

The TEM has a three-axis accelerometer mounted under the concrete and rubber slab the microscope is mounted to and monitors the vibration the microscope is exposed to.

Samples are simultaneously sampled at each location and different sample sites are triggered via a central location to minimise clock drift.

Data is sampled at 2000 samples per second per axis 24 hours a day, 7 days a week and logged into csv files.  In total there are 31 Axes of data collected throughout the building.

Data is uploaded from the data collection server to the storage server in 30 minute intervals.  Data is stored in "g's".

National Instruments NI-9234 module acquiring data at 2KHz, anti-aliasing filter at 900Hz.

Software specifically written to collect, organise and store data onto QUT's storage systems.

Time stamped vibration data from multiple locations throughout the Science and Engineering Centre building on the Gardens Point campus of Queensland University of Technology.  Files are stored in Comma Separated Values (.csv). 

At approximately 90MB/hour/channel, software is required that can handle large datasets such as Mathworks MATLAB or National Instruments DIAdem.

两根结构柱搭载编号为A3与A8的传感器，且两根传感器柱均安装在奇数楼层的天花板楼板上，对应楼层为3、5、7、9层。绝大多数测点可采集三维加速度数据，仅3层A8柱与7层A8柱仅采集X轴加速度数据。
另有两处额外测点：一处为连接建筑的人行天桥，另一处用于监测透射电子显微镜（Transmission Electron Microscope, TEM）下方的振动环境。
该人行天桥共设置8个振动轴同时采集数据，另配备2台声发射（Acoustic Emissions, AE）传感器，分别监测天桥支座与跨中区域的振动。
该透射电子显微镜测点安装了一台三轴加速度传感器，固定于显微镜搭载的混凝土橡胶楼板下方，用于采集显微镜所处环境的振动数据。
各测点同步执行采样操作，并通过中央控制点触发各采样位点的采集任务，以最大限度降低时钟漂移带来的误差。
所有数据以每轴每秒2000个采样点的频率连续采集，全年无休（每日24小时、每周7天），并存储为逗号分隔值（Comma Separated Values, CSV）文件。整个建筑内共采集31个振动轴的数据集。
数据采集服务器每30分钟将采集数据上传至存储服务器，数据以重力加速度单位g为存储量纲。
数据采集采用美国国家仪器（National Instruments, NI）NI-9234模块，采样频率为2kHz，配套900Hz抗混叠滤波器。
本数据集配套专用采集软件，用于数据的采集、整理与存储，并将数据写入昆士兰科技大学（Queensland University of Technology, QUT）的存储系统。
本数据集采集了昆士兰科技大学花园角校区科学与工程中心建筑内多个测点的带时标振动数据，数据文件均以CSV格式存储。
单通道每小时约产生90MB数据量，因此需采用可处理大规模数据集的软件，例如迈特沃克斯（Mathworks）MATLAB或美国国家仪器（NI）DIAdem。
