Research And Design Of Intelligent Controller In Breaker Based On The Embedded Real Time Operation System-μC/OS-Ⅱ

Intelligent Controller is the core of Intelligent Breaker, and software is the soul of it. Software is very important, and affects the stability and performance of Intelligent Controller. The traditional Foreground /Background system does not efficiently make full use of the resource of microprocessor. Furthermore, it is very difficult to develop a complicated system. In the paper, the Embedded RTOS－μC/OS-II is mainly produced. μC/OS-II is a free, portable, ROMable, preemptive, real-time, multi-tasking kernel. Moreover, it comes with source code. μC/OS-II is software that manages the time of microprocessor to ensure that all the critical events are processed as efficiently as possible. WithμC/OS-II, the system will be more reliable, and the ability of anti-jamming must be improved. In the paper, Modbus Serial Line Protocol is also discussed. The Modbus Standard defines an application layer message protocol, which provides "client/server" communication between devices on different types of buses or networks. With Modbus protocol, Intelligent Controllers can contact with each other, and the communication network is also available. Therefore, we can concentrate all the Intelligent Controllers, and control the line system.
