基于CP2200以太網(wǎng)智能節(jié)點(diǎn)的研究與設(shè)計(jì)

工業(yè)領(lǐng)域的設(shè)備集成化、數(shù)字化、網(wǎng)絡(luò)化、智能化已是必然趨勢(shì)，“信息孤島”早已
不能適應(yīng)當(dāng)今的信息化，急需將現(xiàn)場(chǎng)設(shè)備的控制與數(shù)據(jù)采集網(wǎng)絡(luò)化，那么具有通信作用的智能節(jié)點(diǎn)是使設(shè)備網(wǎng)絡(luò)化的關(guān)鍵。CP2200 是工業(yè)領(lǐng)域最小的以太網(wǎng)控制器，它再與單片機(jī)相結(jié)合，便可實(shí)現(xiàn)以太網(wǎng)智能節(jié)點(diǎn)，來完成工業(yè)領(lǐng)域中現(xiàn)場(chǎng)數(shù)據(jù)采集與控制的任務(wù)。

Abstract：It is necessary trend that facility is integrated, digitized, networked and smarted in
industrial field. “Information-isolated-island” early don’t adapt to information of nowadays.
Control and data acquisition of field device is need urgently networking. So smart node carring communication role is key point of making device networked. CP2200 is industry’s smallest Ethernet controller. The integration of CP2200 with monolithic processor is able to realize Ethernet smart node applied to control and data acquisition of industrial field.
