英文摘要：

A new design method of an embedded system,embedded PLC is proposed.There is the detailed introduction of the theory and function of it,the hardware design,kernel design,key technology and the characteristic of the embedded PLC software platform.Based on these,the method and implementation of constituting the communication networks by the embedded PLC is also introduced.The application indicates that using the embedded PLC to develop embedded system,it is easy to achieve the intereonnection of the networks,integrate the information and extend the function.Therefore,the development efficiency of the system is improved and the cycle of the development is reduced.
