The comprehensive seeding accuracy testing method proposed in this dissertation to test performance of precision seeder , grain drill seeder , hill - drop planter , seeding monomer , and seed sowing device is an integrative one with technology of computer vision , patter recognition , and automatic control 本文提出的适用于精密播种机、谷物条播机、穴播机,及排种器等多类型播种机具的播种精度检测方法,是集计算机视觉、模式识别、自动控制为一体的综合技术。
The system has been used in wood drying kiln production process since december 2002 . high precise , real - time scanning , accuracy test is validated by operational result . reliability of measure result , convenience of fit and debug , long distance of signal transmission , lower price and capability of anti - noise are the performance characteristic of this system 半年来,实际运行结果表明,该系统能够高精度、实时巡测窑内温度、平衡含水率、木材含水率等干燥过程基本参数,准确提供干燥状态信息,具有测量参数全面、测量结果可靠、系统功能丰富、安装调试方便、信号传输距离远、检测精度高、成本低、抗干扰能力强等特点。
These methods are developed into programs by matlab6 . 5 software . a series of forecast models are produced by running these programs when related history data of ports in the last decade are input . the most appropriate forecast models are chosen and defined by comparing the related test and the accuracy test 计算是通过用matlab6 . 5软件将这几种预测方法的算法编写成程式进行的,从而得出一系列港口吞吐量的预测模型和未来特征年( 2005年和2010年)的od分布,比较各种模型的相关检验和分布的精度检验,确定预测模型和特征年的分布。
So as to guarantee the company " the tenth five " plan obtained comprehensive implementation , the company has enlarged the check - out facility investment , and has established the pump valve products examination center , increasing a set of great current capacity high accuracy test platform , 5 valve examined test platform as well as various kinds of instrumentation 为保证公司的“十五”规划得到全面实施,公司加大了检测设备的投入,建立了泵阀产品检测中心,新增了大流量高精度试验台一套,阀检测试验台5台,并增加了各类检测仪器。
In new state standard < < machining center testing items - accuracy testing > > [ refering to iso / dis10791 ] , issued in 1999 , the test of straightness accuracy has been changed . now it becomes more scientific and reasonable . in old state standard , the testing of straightness accuracy of kinetic part only focus on vertical and " horizontal plane , and it only includes two linear errors ; but in new state standard , we not only measure those two linear errors , but also measure the errors of pitching , deflecting , and inclining of the kinetic part , so it includes two linear errors and three angle errors 1999年公布的国标《加工中心检验条件?精度检验》 (参照iso dis10791订)中,直线度等项的检测做了更为科学的实质性更改,坐标移动的直线度以由只检测垂直面和水平面内的两个平移线值误差,改为用移动坐标方向之外的另两个坐标的平移线值误差和移动部件绕三个坐标轴的俯仰,偏摆和倾斜三个角值误差综合表征。
