In order to realize the duty better of real-time monitoring and control of power module and UPS in unattended application field in distance, a solution based on embedded system TCP/IP is presented. What is discussed in detail is the hardware design and realization of net node in remote monitoring and control network. The hardware components of the net node include: kernel part consist of microprocessor S3C2410A based on ARM9 and SDRAM, memory module used to store system software and user data, RS-485 bus transceiver based on chip MAX485E, ethernet interface module based on chip CS8900A, color LCD display module and touchscreen module etc. Theoretically, the net node can drive up to 127 intelligent power module or UPS terminals through RS-485 bus. Experiments suggest that the designed net node works correctly in the whole supervising system, and achieves real-time monitoring and controlling of 31 remote terminals.
