pipe percussion dataset

The data is the signal data collected by tapping two pipes of the same specification at five different locations under seven different working conditions. Data set 1 and data set 2 correspond to two pipelines respectively, and A-G in them correspond to seven different working conditions. Working condition 1 is the original pipeline without corrosion, and working condition 2 is the pipeline 10h after the first corrosion, which is followed by 5 times of corrosion for 6 hours each time. Therefore, working condition 7 is the pipeline after 40h corrosion. The values 1-5 in each working condition indicate the different tapping positions of each pipe, with the same spacing between each two adjacent tapping positions. The numbers 1-110 in the table represent 110 strokes at each tap position. In terms of corrosion, two carbon rods are connected to the power supply and electrochemical corrosion is carried out inside the pipeline to produce different working conditions. In the acquisition, the microphone of BK company is used as the acquisition device, connected to the acquisition card of NI company, the acquisition card is inserted into the acquisition chassis, and the chassis is connected to the notebook, and the acquisition is carried out through the labview program.

本数据集为在七种不同工况下，于两根同规格管道的五个不同位置敲击采集得到的信号数据。数据集1与数据集2分别对应两根待测管道，其中标识A至G对应七种不同工况。工况1为无腐蚀的原始管道；工况2为首次腐蚀10小时后的管道，后续依次开展五次每次持续6小时的腐蚀作业，因此工况7为累计腐蚀40小时后的管道。每个工况下的1至5代表单根管道的不同敲击位置，相邻敲击位置间距一致。表格中的1至110代表每个敲击位置下的110次敲击采样。腐蚀环节通过将两根碳棒连接至电源，在管道内部实施电化学腐蚀，以生成不同的工况状态。数据采集环节采用布鲁埃尔&凯耶（BK）公司的麦克风作为采集设备，该设备连接至国家仪器（NI）公司的采集卡，采集卡插入采集机箱，机箱与笔记本电脑相连，并通过LabVIEW程序完成数据采集。
