The design and implementation of circuit breaker on-line monitoring device

This paper designed a circuit breaker on-line monitoring system based on S3C2440A core controller. With the high speed and high precision extended A/D, this device can sample signals on real time. It is fast, easy networking and convenient for remote data transmission by Ethernet. The embedded linux operating system, which can be cut arbitrarily and easy to translate, is used in this device. This monitoring system has complete functions, and has the advantages of user management and real-time multitasking. Tests show that the system can sample quickly and accurately, and transmit data fast and safely. System´s anti-interference ability is strong, performance is stabilized and the bit error rate is low. So, it is better than the traditional 485 communication way.
