基于ARM和DSP的双变量施肥控制系统设计与试验(ARM and DSP-based Bivariable Fertilizing Control System Design and Implementation)
变量施肥机 实时控制系统 ARM DSP
2010/12/29
设计了一种开度、转速双调节变量施肥机控制系统的嵌入式解决方案,该系统集GPS和GPRS于一体,开发了基于ARM和DSP双CPU架构的嵌入式系统平台。上位机利用ARM9和WinCE系统支持图形化人机界面和触摸操作,能够实现施肥生产过程的信息输入与作业状况的实时反映;下位机利用DSP/BIOS实时操作系统完成排肥口开度和施肥轴转速的电动机伺服控制。详细阐述了系统软硬件结构及总体设计方案。该系统软硬件具...
基于SVM快速增量算法的HACCP控制点分类(Fast Incremental SVM Method for Classification of CCPs on HACCP Implementation)
危害分析与关键控制点 支持向量机 增量学习
2009/11/3
支持向量机方法已经在HACCP体系关键控制点的智能发现中取得较为满意的结果,但是在样本不断增加的情况下分类效率不高。本文采用支持向量机增量学习算法,优先选择可能成为支持向量的边界向量,减少参与训练的样本数量,进而实现增量学习。实验证明,改进的支持向量机增量算法在保证分类精度的同时,显著提高了分类速度。
