Design And Implementation Of Embedded Residential Gateway Based On Lpc2210 And UClinux

With the rapid development of computer technology and network technology, the embedded system has won a huge chance to develop. Recently, the embedded system has been applied widely in all kinds of field. Moreover, ARM which is 32-bit embedded RISC microprocessor, has been spread to the range of the world, and occupied in the field of application of low consumption, low cost and high performance embedded system. And, the embedded web technology will be the key technology of building long-distance distributed Measurement and Control system based on Internet, it plays an important role in web technology penetrating in the field of measurement and control as well as the field of tel-communication instrument, also it will bring an important innovation in information field.The task chooses lpc2210 chip of Philips based-on ARM7. Considering embedded Linux is getting more and more attention for it's free, open-code and strong network supported characteristic, therefore, the author chooses uClinux as software platform. Based on the platform described above, the author replants embedded web server BOA to implement the embedded gateway application system with CGI technology. The embedded gateway connects with intelligent devices by RS485 BUS in the task, it makes users to access and control intelligent devices by explorer outside the field.The embedded gateway realizes long-distance distributed measurement and control, has natural price ratio, can be applied to industry control, traffic control; also can be suitable for home area, then the embedded gateway may be called embedded residential gateway.
