  • CAN基本知識

    CAN,全稱為“Controller Area Network”,即控制器局域網(wǎng),是國際上應用最廣泛的現(xiàn)場總線之一。最初,CAN被設(shè)計作為汽車環(huán)境中的微控制器通訊,在車載各電子控制裝置ECU之間交換信息,形成汽車電子控制網(wǎng)絡(luò)。比如:發(fā)動機管理系統(tǒng)、變速箱控制器、儀表裝備、電子主干系統(tǒng)中,均嵌入CAN控制裝置。一個由CAN 總線構(gòu)成的單一網(wǎng)絡(luò)中,理論上可以掛接無數(shù)個節(jié)點。實際應用中,節(jié)點數(shù)目受網(wǎng)絡(luò)硬件的電氣特性所限制。例如,當使用Philips P82C250作為CAN收發(fā)器時,同一網(wǎng)絡(luò)中允許掛接110個節(jié)點。CAN 可提供高達1Mbit/s的數(shù)據(jù)傳輸速率,這使實時控制變得非常容易。另外,硬件的錯誤檢定特性也增強了CAN的抗電磁干擾能力。
