Design and Application Of Yield MOnitor System for Corn Ear
摘要
Abstract
A yield monitor system for corn ear was designed and applied in field. It is consisted of a monitor, a ground speed sensor, a yield sensor, a DGPS, a header sensor, an elevator speed sensor and the guiding device. The data of grain-ear ratio and moisture content of corn grains were sampled before harvest. The header sensor was used as a logic switch of the system while harvesting corn ears. All the corns were forced to impact the yield sensor at the same speed with the help of the guiding device. The monitor received signals coming from the yield sensor, the ground speed sensor, the elevator speed sensor and the DGPS worked out the yield in the plot and saved it in the file with extension of ". Vld". The yield map would be drawn by means of the self-developed DCAS ( data collecting and application system) . This system was applied in field in the autumn of 2009. The data of the experiment showed that the average relative error of the yield monitor system was 18. 11% .关键词
