【Abstract】 Several methods of MCU embedded internet were compared and discussed according to the tendency of development of home network.An embedded scheme was put forward,based on the SX MCU with its virtual software modules and ethernet control chip RTL8019AS. With the help of SX MCU virtual IrDA interface module, this scheme was applied to the system of long distance temperature collection an d control. The system framework and relative design of application software were introduced. This embedded scheme is reasonable and economical,easy to put to p ractice,and can promote popularity of the application of home network.更多还原
