摘　　要：为了解决工业控制中自确认执行器的数据采集与传输问题,同时满足工业执行器控制中的高速率和高可靠性,提出了一种基于TMS320F28335和C8051F060片内集成CAN模块构成的CAN总线通信系统。对CAN总线的优点、工业应用情况、基本结构、硬件设计、软件设计和CAN总线的位时间配置等方面做了详细论述,搭建了基于自确认执行器硬件平台的CAN总线通讯系统并进行了实验。实验结果表明,系统可以满足自确认气动执行器CAN节点的数据采集、传输和控制功能。In order to solve the data collection and transmission problem of self-validating pneumatic actua- tor in industrial control while meeting the high-speed and high reliability requirements, a CAN-bus communi- cation system based on CAN-module integrated in TMS320F28335 and C8051F060 is presented. First of all, the CAN bus advantages,industrial applications,basic structures,hardware design,software design and the configurations of CAN-bit timing are expounded in detail. Then, a CAN communication system is established based on self-validating pneumatic actuator hardware platform. The experimental results indicate that the sys- tem can meet the data collecting, transmitting and controlling functions of the self-validating pneumatic actu- ator CAN nodes.
