Abstract:  With continous deepening of network, the localization database has been unable to meet the terminals, platforms, and devices collaboration needs. The traditional database acquisition system to collect data algorithm is of slow speed, and it lacks of the ablility of computing in the background. Aiming at a series of problems in the traditional database, networked database data acquisition system design method is put forward. The method used UMTA to interact data in different terminals, so as to optimize the upload data. At the same time, we used DTIT to image terminal data real-time dynamically, in order to ensure data upload obtaining in offline. Design method was tested by simulation experiment, the test results show that the design of networked database data acquistions system of data acquisition and data processing arithmetic has high stability and efficiency, the overall performance of the designed system satisfied the requirement of data acquisition.
