检测精密排种器性能虚拟仪器的设计

Detection of a Precise Seedmeter Performance Using Virtual Instrumentation

介绍了NI公司推出的虚拟仪器LabWindows/CVI6.0在内侧充种垂直圆盘排种器测试方面的应用;研究了能检测双粒(或多粒)重播情况的检测系统;通过软件设计可以得出各种评价指标—合格指数、重播指数、漏播指数、平均值、标准差及变异系数等。试验表明,检测系统精度满足精密排种器性能要求。

Introduce virtual instrumentation LabWindows/CVI6.0 tapped by NI corporation application on the vertical-plate feeding seed-cell on inside seedmeter test, study the test system that can test double(or multiple) condition, Through software designed,it can draw varies estimating indexes: qualified, rebroadcast,loss,average, standard deviation and variance modulus etc; The experiment showed the test system fulfilled seedmeter test requirements.
