摘　　要：随着计算机技术、微处理器技术以及通讯技术的不断发展,传统仪表己经不能适应工控的要求。而CAN总线控制器的出现为工业控制系统向分散化、网络化发展等开辟了新的空间。CAN控制器具有良好的稳定性、高可靠性、较快的通讯速率以及低成本等特点,且能够有效支持实时、分布式控制,从而应用于许多领域,本设计针对内嵌CAN的STM32F103RC处理器进行深入研究,并以它为核心部件进行CAN控制器软硬件的设计,该控制器兼容模拟量数字量的输入,保证了通用性并具有较大的应用范围。在采集与输出通道数量方面也得到了保障。例如由于工业需求要增加监测点或执行点,本控制器可以解决此问题。从长远考虑会降低用户的投资成本,本控制器可以与其他CAN节点及上位机组成CAN总线远程监控系统,实现仪表网络化,智能化。With the continuous development of computer technology, microprocessor technology and communications technology, the traditional instrumentation already can not meet the requirements of the IPC. CAN bus controller for the industrial control system to a decentralized, network development has opened a new space. CAN controller has a good stability, high reliability, faster communication speed and low cost, and can effectively support real-time, distributed control, and thus used in many fields, This design in--depth study of embedded CAN STM32F103RC processors and it is the core component of the CAN controller hardware and software design from a structural point of view, The controller is compatible with analog digital input, to ensure versatility and has a large range of applications. Also guaranteed in the acquisition and the number of output channels. For example, the industry needs to increase the monitoring point or point of execution, the controller can solve this problem. Will reduce the investment cost of the user＇s long-term consideration, and CAN bus controller can be composed with other CAN nodes and PC remote monitoring system to achieve the instrument network and intellieent.
