Research on Data Acquisition Technology of Embedded Mobile Terminal

ABSTRACT

In this paper, database acquisition system is composed by three modules, that is hardware of the embedded mobile terminals, transmission and acquisition of data data processing of server database. The core component of the embedded mobile terminals consists of a CPU of Cortex-A8, GPS, network cards, keys and display screens etc, in order to realize order form information acquisition and supervisory control online of logistics systems. Data transmission and acquisition take 3G technology as premise of data transmission and acquisition, Internet work as supporter, cache and FIFO algorithm as techniques, transfer data information of embedded mobile terminals to former server. Server database take charge data maintenance and processing, realize the instantaneity of data, and provide server of on-line inquiry. The three part supplement each other, collectively realize data acquisition of whole logistics database, so as to meet the needs of real- time of business management of logistics industry, gain integrated management model of data flow and information flow, supply an informative platform of logistics management, promote the management level of logistics industry.
