Design and Data Processing of AD Acquisition Program Based on LabVIEW—Motor Speed Detection as an Example
2018
Using LabVIEW as the software platform, the Altai PCI8932 signal acquisition card is the hardware. According to the motor speed detection project, the design and data processing of the AD acquisition program are carrying out, and the test of the motor speed frequency is completed. Based on the PCI driver function, a complete AD processing program is designed. The arithmetic average filtering algorithm and scale conversion data processing scheme are programmed for graphics in data acquisition process. To achieve more accurate and stable sampling data, it provides the basis for the later application of motor speed data (PID, result output).
