摘要
随着工矿企业自动化程度的提高,设计了一种基于DMA方式的高速数据采集节点,采用新型系统级单片机,对节点中的高速缓存、CAN总线通讯接口等内容进行了讨论,阐述了同步采集的方法,结合节点的软硬件设计,给出了一些器件初始化程序的C51代码和部分模块的接口电路图。
With the increased automation of industrial and mining enterprises, proposing a design of the high-speed DAQ on basis of the DMA mode, using the new system-level single chip, discussing the cache, CAN bus interface and so on, expounding the synchronous acquisition method. The software design and code realization of the system are given in this paper. Combination of hardware design, some C51 code of the initialization procedure and interface circuit diagram are given in this paper.
