The measurement device and principle using weighing method were introduced briefly in the thesis. Data acquisition device and vehicle-mount computer were designed for the measuring system. By using measuring software designed for the system, user could obtain the grain mass and harvest area in field by computing the collected data. The experimental research demonstrated that the relative error of measuring system was less than 2% in laboratory and less than 3% in field by using weighing method.
