为了适应家电系统的要求和针对现有的MCU、ARM监控系统设计的不利扩展性和设计的复杂性,提出了基于GPRS、Internet和SOPC家电远程监控系统的方案。采用FPGA设计了基于NiosⅡ软核处理器和IP组件的家庭网关硬件系统;并在NiosⅡ处理器上移植uClinux操作系统、采用嵌入式C语言编写了CGI程序实现动态Web服务器交互式访问。系统实现了GPRS无线接入和Internet有线接入访问Web服务器,系统真正意义实现了SOPC。
In order to meet the requirements of home appliance system and to address the disadvantageous scalability and design complexity of the existing MCU and ARM monitoring system design, a remote monitoring system based on GPRS, Internet and SOPC appliances is proposed. The home gateway hardware system based on Nios Ⅱ soft core processor and IP component was designed by FPGA. The uClinux operating system was transplanted to Nios Ⅱ processor and the CGI program was written by embedded C language to realize dynamic Web server interactive access. The system realizes GPRS wireless access and Internet wired access to access the Web server, and the system realizes SOPC.
