Research on Data Acquisition Technology of Embedded Mobile Terminal

摘要

In this paper, database acquisition system is composed by three modules, that is hardware of the embeddedmobile terminals, transmission and acquisition of data data processing of server database. The core component of the embeddedmobile terminals consists of a CPU of Cortex-A8, GPS, network cards, keys and display screens etc, in order torealize order form information acquisition and supervisory control online of logistics systems. Data transmission and acquisitiontake 3G technology as premise of data transmission and acquisition, Internet work as supporter, cache and FIFOalgorithm as techniques, transfer data information of embedded mobile terminals to former server. Server database takecharge data maintenance and processing, realize the instantaneity of data, and provide server of on-line inquiry. The threepart 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 informationflow, supply an informative platform of logistics management, promote the management level of logistics industry.
