现场总线技术在SSM120优质大米筛选系统中的应用

Application of locale bus based on rice-selected system of SSM120

详细介绍了基于现场总线技术和TMS320LF2047的优质大米筛选系统的总体结构。讨论了该DSP和CAN(pcl841)的通讯协议,并在基于模式识别的基础上解决了电荷耦合器件的色谱分析问题。同时描述了主程序流程及其控制功能。实验结果表明系统设计的合理性与功能设计的灵活性和可靠性。

In this paper, the hardware structure of the Rice-selected system based on locale bus and TMS320LF2407 is introduced in detail. The communication protocol between the DSP and Card of CAN is discussed, and the question of Charge Coupled Device＇s chromatographic analysis on the basis of pattern recognition is solved. The flow chart of the main program and the control function is described. In the end we can see the rationality of the system and the flexibility of the function design from the experimental results.
