The electrical automation embedded control system is such an automatic control system in which one or several independent full-featured small or micro computer devices as a component or subsystems are combined with control system organically to construct a more powerful and more sophisticated automatic control system. From perspectives of the processing power and the characteristics of handling signals, the commonly used embedded processors include such four types as single-chip microcontrollers, digital signal processors, embedded microprocessors, on-chip systems. There are a lot of common embedded real-time operating systems. The performance, functionality, cost and applications of WinCE, Linux and eCos have been analyzed and compared. It has great reference and guidance significance for people to develop and apply the embedded systems. The automation embedded systems will develop in network, rapid, market-oriented, concise, scientific, environmental direction.
