CAN总线在多通道批量控制器中的应用

摘要

With the development of automation, multi processor system together to accomplish a task has become a trend in trend in the development process,the data exchange between the research has also become a focus. This paper based on multi-channel batch controller data transmission requirements,designed the multi-channel batch controller based on CAN bus. It described the hardware connection between the MSP430 with SJA1000,combined with designed of transmission characteristics of data based on application layer software CAN design. Experiments show that the communication system performance is stable and reliable, based on a high practical value.%随着自动化的发展,多处理器共同完成一个系统的任务成为了发展的趋势,多处理之间的数据交换也成为了研究重点.文中根据多通道批量控制器的数据传输要求,提出了基于CAN总线的多通道批量控制系统设计方案,描述了MSP430与SJA1000之间的硬件连接,并结合传输数据的特点设计了基于CAN的应用层软件设计要点.实验表明:该通信系统性能稳定、可靠、基于较高的实用价值.
