In recent years , with the development of communication technologies , digital protection devices are also improved . in this paper , the communications that are used in digital protection device and the protocol they followed are studied . as a kind of field bus technology , can ( control area network ) is applied to the communications of double mcu , which has higher reliability and strong transmission ability
同以往的通信技术相比， can信号传输采用短帧结构，每帧的有效字节数为8个，因而传输时间短，受干扰的概率低，当节点严重错误时，具有自动关闭的功能，以切断该节点与总线的联系，使总线上的其他节点和通信不受影响，具有较强的抗干扰能力。
