In order to realize remote monitoring of environment and equipment at low cost, a remote monitoring system based on Embedded Ethernet is designed by using MSP430 Microcontroller Unit (MCU) and CS8900A network controller. The overall structure of the system and the design of software and hardware are introduced. Embedded Ethernet is implemented by transplanting simplified TCP/IP protocol stack. Embedded web pages are stored in Flash memory of MSP430 MCU, and an embedded remote monitoring server is constructed through hardware and software cooperation. Users can visit the embedded web pages to view and remote manage the system at any time through the network, so as to realize the remote monitoring of the system. The experimental results show that the system can meet the design requirements and the system design scheme is feasible.
