| Abstract: | This virtual instrument measurement system uses the grain loss sensor made by the author,charge amplifier, wavebook516,uses DASYLAB programming the measurement code,and carries out an indoor simulation experiment according to real operating mode. It is proved that this system can discriminate the grain loss from the straw which is originally discharged form the back of the combines quite exactly. This paper performs dynamic online test of grain loss at home firstly,This study provides useful experience and data as well as new ideas for the applications of virtual instrument technique in agricultural engineering. |
