I have encountered many problems in the process of using NI products for data collection. Among them, the way of data collection and storage is very important and related to the results of our experiments. LabVIEW provides three commonly used waveform data storage methods, namely bin, txt, and tdms. The first two types of data may be familiar to everyone and are easy to operate, but there will be some problems in the process of using these two types of data. As the amount of data you need to save increases, you will find that these two types of data require a lot of space, especially txt, which takes some time to open, which is not very convenient. I once wrote a data storage program that requires long-term detection of equipment. If you keep writing data in a file, it feels that the running speed of the program will decrease. Here I want to talk more about tdms, which is a data storage format that can be used by LabVIEW, Labwindows/CVI. For the same amount of data, tdms requires about half the space of bin, and it can also be very convenient to set various properties of the waveform like bin. For equipment that needs long-term detection, NI engineers have provided a programming method called data flow, which is very effective and convenient. The structure diagram of the program they provide is posted below. If you need it, you can contact me and learn from each other.
