Abstract: At present,data acquisition in the field environment mainly relies on the data collector to fill out the preset form manually,and then submit it to the data entry staff to input into the computer database.This method of data acquisition involvesmulti-person work,the process is complex,the data are easy to lose,and the quality of data is difficult to guarantee.To solve these problems,this paper designed and implemented a handheld terminal based on embedded microprocessor PXA270.The terminal integrates wired and wireless local area network,GPRS/GSM wide area network and other means of communication in hardware,integrates various encryption techniques in software,and compiles encrypted communication software within wide area network on WinCE platform,which can effectively solve data real-time transmission and security issues under field conditions.

Key words: Data acquisition, Data encryption, Embedded design, GPRS, WinCE
