摘要
针对双CPU测控系统中,要求数据传输稳定的问题,提出利用CAN总线技术进行远程数据采集传输的方案。以单片机AT89C52,CAN控制器SJA1000以及DSP芯片TMS320LF2407为例,介绍了单片机和数字信号处理器CAN通信系统设计,并给出接口电路和编程。试验证明,利用CAN总线实现双CPU系统之间的数据通信具有速度快、可靠性高、实时性强等显著特点。
In some measurement and control system, a system with stability in remote communication is necessary, this paper proposes one scheme, which is intended to transmit sampled data to remote site by using CAN technology. Takes AT89C52,SJA1000 and TMS320LF2407 for example to introduce the design on communication system of single chip microcomputer and DSP based on CAN - bus and sets forth its interface Circuit and software. Experiments prove that the use of CAN - bus to achieve high speed data communication of the dual -CPU system has high -reliability, real -time, and other significant characteristics.
