The Research And Design Of Wireless Terminal Of Monitoring System Based On ARM9

Since the IEEE 802.11b/g WLAN (Wireless Local Area Network) standard was drawn up, Wireless Broadband Communications technology had a rapid development. And with the embedded technology goes deep into nearly each fields of our work and life, the wireless access of embedded system will have very broad application prospects. The monitoring system of industrial automation needs to collect much data and information of cameras, sensors and other different equipments, and people can check and operate with a wireless hand-hold terminal, which could extremely improve efficiency. This paper has done research on the design of wireless terminal based on embedded technology and the integration of monitoring system.In this paper, there is an in-depth research on the embedded microprocessor based on ARM technology, the basic architecture of embedded system, the establishment of cross compiler environment and the Linux system device driver. This paper designs and implements the successful runningg on the embedded platform of USB wireless card. This paper discusses the controlling method of camera and cradle motor based on embedded platform, and implements the remote monitoring function. The wireless terminal based on MiniGUI graphic design adopts a modularization idea, implements the remote controlling of motor rotating and camera shooting with Telnet rlogin method through the wireless card and achieves the previous expectation.
