Network Module Design of miniRTU

With the ten years’ development of Internet technology, Ethernet has become the leading technology for business communication. Industrial Ethernet technology is the Internet technology used in industry. In this paper, based on the platform of ARM7 and by embedding TCP / IP protocol into the embedded system the network communication functions are achieved. The specific content includes the designs on hardware and software of network module. The hardware design includes the design of network control chip and external circuit while the software design involves the design of bottom driver and TCP/IP protocol. The system is applicable for distance letter, telemetry, remote control functions in water conservancy, power scheduling, municipal scheduling, and other industries.
