This paper designs a general data acquisition and management system using indigenously developed card and Paradox database based on portable computers. It has sensors to key phase, displacements and accelerations and can be used for steady and instantaneous signal sampling and analysis of rotating and reciprocating machineries. It discusses selection of the database type, establishes the fast querying structure and realizes the function of data sampling and management. The experimental results show that the system is reliable and easy to upgrade.
