1 CAN BUS的基本介绍cAN的全称为Controller Area Network,最初出现在80年代末的汽车工业中,由德国Bosch (博世)公司最先提出。1993年,CAN已成为国际标准ISO 11898(高速应用)和ISO 11519(低速应用)。CAN是一种多主方式的串行通讯总线,基本设计规范要求有高的位速率,高抗电磁干扰性,而且能够检测出产生的任何错误。当信号传输距离达到10 km时,CAN仍可提供高达5 kbit／s的数据传输速率。由于CAN总线具有很高的实时性能,因此CAN已经在汽车工业、航
1 CAN BUS basic introduction The full name of cAN Controller Area Network, first appeared in the late 1980s in the automotive industry, first proposed by the German company Bosch (Bosch). In 1993, CAN has become the international standard ISO 11898 (high-speed applications) and ISO 11519 (low-speed applications). CAN is a multi-master serial communication bus. The basic design specifications require a high bit rate, high immunity to electromagnetic interference, and the ability to detect any errors that occur. When the signal transmission distance reaches 10 km, CAN still can offer the data transmission rate up to 5 kbit / s. Since CAN bus has high real-time performance, CAN has been in the automotive industry, aviation
