Database Design in Data Acquisition System for Electric Vehicle´s Driving Motor Test Bench

Although widely used in data acquisition system, LabVIEW doesn´t provide direct accesses to database. In this paper, several methods accessing to database indirectly in LabVIEW are presented, and their advantages and disadvantages are discussed. Based on the discussion, the method that using user-developed database toolkit LabSQL is adopted, and the principle communicating with Microsoft Access Database is illustrated. In addition, according to the actual requirements of data acquisition system used for electric vehicle´s driving motor test bench, programs realizing function of add, query and delete operations are designed to manage data automatically. And with the help of this database system, the information management for the experiment of electric vehicle´s driving motor is improved drastically.
