We used National Instruments cards NI PCI-6251, NI PCIe-M6251, and NI PCI-M6040. Acquisition cards are available in a broad range for various tasks and quality requirements. The time series, most often in the form of parallel voltage signals, enter the program through a number of channels of an acquisition card, building the interface between computers and experimental setups. Running time: As desirable: microseconds to hoursĪ time series can originate from a wide range of physical signals, such as temperature, voltage, current, etc. Restrictions: Only tested in Windows-operating LabVIEW environments, must use TDMS format, acquisition cards must be LabVIEW compatible, driver DAQmx installed. The program can be easily customized for time series analyses. In particular, the program is optimized to deal with large amounts of data, e.g., taken with high sampling frequencies and over long time intervals. Due to optimized timing and usage of computational resources, such as multicores and protocols for memory usage, this program provides extremely reliable data acquisition. Solution method: This LabVIEW program is developed to directly stream any kind of time series onto a hard disk. This type of data acquisition often produces very large amounts of data not easily streamed onto a computer hard disk using standard methods. Nature of problem: For numerous scientific and engineering applications, it is highly desirable to have an efficient, reliable, and flexible program to perform data streaming of time series sampled with high frequencies and possibly for long time intervals. Operating system: Windows XP and Windows 7 of bytes in distributed program, including test data, etc.: 63 259Ĭomputer: Any machine running LabVIEW 8.6 or higher of lines in distributed program, including test data, etc.: 250 Licensing provisions: Standard CPC licence, Program obtainable from: CPC Program Library, Queen's University, Belfast, N. ![]()
