Research On An Intelligent Monitor For Yield Mapping Of Cotton Picker

This research was supported by a cooperative project—Testing and Application of the Imported Cotton Yield Monitoring System & Research of National Technology, conducted by the Science and Technique Committee of Shihezi in Xinjiang and the Research Centre for Precision Agriculture of China Agriculture University.With the development of precision agriculture (PA), the supporting technique is developing rapidly. Crop information collection and correlative equipment development become more and more important in applied information technology innovation research. The PF yield monitoring system of Ag Leader Corporation was studied deeply. With the three-year cotton field testing, it obtained more important harvesting experience and yield data were obtained. A new yield monitor was developed at the Research Center for Precision Agriculture (PAC) of China Agricultural University.PF cotton yield monitoring system is consisted of a yield monitor, cotton flow sensor, head height sensor, ground speed sensor, fan speed sensor. GPS receiver and other components. The cotton flow sensor is the most important part of the system. In addition, a sort named SMS Basic for data processing was applied.The designed yield monitoring system can collect 4 analog signals and 3 digital signals, and can receive DGPS signal at same time. It stores these signals to CF card once per second. A liquid crystal display and a touch screen were integrated to input and output signals. A friendly interface was designed. Field tests show that the system can finish the yield-monitoring task. It runs normally and stably. The accuracy of the system depends on appropriate installation, calibration, and operation. And the cost of the system is very low comparing with the commercial products on the market.
