Abstract: A design of the main controller applicable to Distributed Control System(DCS) is presented. The hardware platform of the main controller centers on the high-performance processor is based on PowerPC architecture, and the software platform is based on μC/OS-Ⅱ operating system. Dual parallel processing CPU unit is employed to improve the computing efficiency of main controller. The redundant topology of working and backup controller is used to attain higher reliability. PCI-Express communication interface is employed to assure the high-speed redundant communication between working and backup controller. Test results prove that the main controller has high reliability and excellent computing performance.

Key words: main controller, PowerPC architecture, μC/OS-Ⅱ operating system, dual CPU, redundant communication
