The Design of Remote Frequent Collection Based on ARM9

The paper introduce the design of system of frequent signal collection.The hardware's core are arm embedded processor S3C2440 and Ethernet interface chip DM9000 with 10/100M bit/s self-adaption.The system include signal collection, frequent signal measure, arm embedded process system and Ethernet interface.The software adopt embedded linux operating system, TCP protocol are used in communication.The system have power Ethernet function so the data can be transfered to remote fault diagnosis centre by internet.
