【摘要】 以PDA移动设备为硬件平台,在Windows mobile操作系统上,采用Visual Studio 2005、.NET CompactFramework和SQL mobile等软件,针对荷斯坦奶牛线性评分的1-50分制的标准和转换为1-9分制的原理,开发完成了PDA奶牛体型线性评分嵌入式系统。与具有大内存和高速CPU的电脑比较,开发的PDA移动系统同样可以在现场对奶牛主要性状的线性评分数据进行录入、分值转化和体型总分计算,也可对特定牛群的体型线性评分的优劣分布(如优、良、佳、好、中、差等)进行统计图形分析处理。此外,指出了开发的PDA系统今后应与图像采集与数字化处理技术相结合,使得线性评分的依据更客观、整体评分结果更接近实际。更多还原

【Abstract】 Based on PDA mobile equipment and Windows mobile operation system,as well as Visual Studio 2005,.NET Compact Framework and SQL mobiles software technologies etc.,in this stud,1 to 50 score standard and transfer into 1 to 9 score standard of linear evaluation for Holstein cattle were introduced,and an embedded PDA system of linear evaluation for dairy cattle was developed.The final results showed that the system had the same performances with the system designed on the table or notebook computer with both high capacity memory and high speed CPU.It can deal with on-line data and store a lot of records,and even do some styles graph-analysis according to good and bad distribution of evaluating results.Those results include excellent,very good,good,relative good,middle and bad etc.Furthermore,the future improved orientation of this PDA system is to combine digital pictures collecting and digital process,and to get indirect and more exact body measurement so that to get impersonal linear scores and final whole body evaluation.更多还原
