| Abstract: | A simple , versatile , portable data acquisition and processing system based on computer＆#39;s sound card is designed by LabVIEW software .The system can realize real-time data acquisition ,online analysis and multifunctional off-line analysis ,which makes it have higher practical application value .Using database technology to write the user login module is able to ensure the security of the system . The producer/consumer model structure is taken as the overall framework to prevent data losing and overflowing and ensure the integrity of the data .Finally ,the sound and vibration toolkit in LabVIEW is applied to this system , which provides a basis for the maintenance and extension of the system . |
