中文摘要:运用VB 6.0编程语言设计了应用于谷物联合收获机称量式测产系统平台的测产软件。该软件能实时接收、显示和保存测产系统所采集的数据,计算得到实时收获总质量、收获面积等田间信息。软件对谷物流量数据计算处理作出谷物流量图;将GPS接收到的经纬度转换为高斯坐标,在平面直角坐标系中作出GPS轨迹图;最终将流量数据与GPS轨迹数据结合运算生成产量图。作图过程中当曲线即将到达界面边界时,曲线图会自动平移远离边界以保证实时图像的正常显示,在作图结束后可拖拽图像查看完整图形。经测试,软件在室内测产相对误差小于2%,在田间测产相对误差小于3%。

Abstract:A yield monitoring software was developed by VB programming language could be applied to combine harvester based on weighing. The data collected by yield monitor system could be displayed and saved by the software in real time. The software could get the harvesting total mass and the area, and draw the grain flow diagram by computing the grain flow data. It can also convert the latitude and longitude data received from GPS into Gauss coordinate, and then draw GPS locus diagram in rectangular plane coordinate system. Finally, the software can draw the yield map automatically by using the grain flow data and GPS locus data at the same time. During the process of drawing the map, the map will move itself far away from the border of interface to ensure the real time curve displaying normally before the curve arrives the border of interface. After finishing drawing, the map could be dragged in the interface freely to check the whole map. The yield monitor precision was less than 2% in laboratory and less than 3% in field.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
