The paper introduces the study of signal communicaiton and analysis based on DSP and Lab-VIEW. DSP is used for data acquisition and its serial communication module is configured. LabVIEW is used for developing upper computer communication program and data processing program to realize vibration sig-nal processing, display and storage. The paper presents a real-time acquisition, rapid processing and high cost performance data acquisition and processing system,and it can be used to monitor working condition and diag-nose fault of rotary machines.
