摘要: A system attached to a small harvester and able to navigate was studied to analyse distribution information on wheat yield while reaping. In this system, a balance-based yield flowmeter was built to detect the weight of moving wheat. Coordinate transform methods were employed to reduce errors. GPS receivers and GIS technology were used to report coordinates and the corresponding yield data, based on which a yield map could be displayed synchronously, and the harvester track could be displayed on a digital map drawn by the system. A meter was programmed to accumulate and display the reaped area on a screen with data from a GPS receiver and header switch. Experiments showed that the system can detect wheat weight with an error less than 3.5%, and it can create a digital map rapidly and display the harvester's track as it moves. The reaped area was synchronously shown with errors less than 2.4%.
