摘要
为了保证数据传输的实时性、可靠性,解决数据传输过程中易受干扰的问题,并保证数据采集和控制系统的性能,采用CAN总线作为现场总线来实现数据传输。经过对系统软硬件在不同环境下的多次测试,验证了该系统的性能,同时也体现了CAN总线在通信能力、可靠性和实时性等方面的明显优势。
In order to ensure real-time and reliable data transmission,solve the problem that the data is prone to be interfered in the process of data transmission,and ensure the capability of the data acquisition and control system,CAN(controller area network) bus is taken as the fieldbus in the system to realize data transmission.CAN is a kind of serial communication network that supports the distributed control and the real time control,and has the characteristics of high performance and high reliability.The repeated tests for the hardware and software of the system demonstrates the capability of the system,and embodies the obvious advantage of CAN bus in the aspects of the communication capability,reliability,real time,and so on.
