基于LPC2292单片机的通信单元的设计

The design of Commutation Unit based on LPC2292

LPC2292单片机是基于arm7核的32位单片机。基于arm7核的设计,从硬件的结构上和速度上为实时操作系统的移植提供便利。在设计中充分考虑到LPC2292所具备的这种优点,通过移植实时操作系统uCosll,完成从CAN总线到以太网的协议转换。可以方便地用于变电站自动化底层中CAN网络与以太网层的互联。

LPC2292 based on arm7 core is a 32-bits microprocessor. The design of arm7 core would ease the transplant the real time operation uCosll. The design takes advantage of the merits of LPC2292. Through the transplant of uCosⅡ , the translation between CAN protocol and Ethemet protocol has been successfully fulfilled. The design can be conventionally used in the substation automation to link CAN and Ethemet.
