ARM-based Security Architecture Development And Application Of Network Information System

Research and development of this project based on ARM technology and network of building intelligent information technology security network information system, Internet remote control and ARM control technologies combine to achieve a system of data processing and wireless control, avoiding the cabling, as ARM-based design, good system scalability. This paper first describes the overall system, combined with Ethernet technology and the ARM target board's power, the system is divided into data processing module, SPI interface module, MODEM module and Ethernet module, and then made Ethernet comprehensive analysis, combined with the target board, debugging developed a WEB server functionality of the system. In order to facilitate data processing, we developed the ADC modules target board; follow-up functions for the realization of development, development of a MODEM module; take into account the requirement of real time systems real time operating system for transplantationμC/OS-Ⅱ. The design is completed on the target board of SPI, ADC, MODEM module functions of the development, simultaneously ENC28J60 Ethernet-based control module programming.
