为实现对插秧机作业区域和作业边界的自动识别以及作业面积的实时自动测量和其他相关数据采集,对插秧机作业面积自动测量系统电路进行了设计。系统主要由中央处理模块、传感器检测模块、GPS定位模块、无线数传模块、U盘数据存储模块、电源模块以及上位机远程监控模块等7部分组成。中央处理模块的主控芯片采用STC12C5A60S2单片机,主要负责采集和处理GPS定位模块以及传感器检测模块对插秧机的定位轨迹信息、发动机其他工况参数信息,并通过对GPS定位信息的分析处理完成插秧机作业面积的自动计算;无线数传模块主要负责完成与上位机之间的通讯工作;上位机远程监控模块负责通过GPRS组网技术与PC机相连,并能实现对插秧机远程启停动作。结果表明,该系统能实现对插秧机作业面积的自动测量,并能实现对插秧机作业面积的远程监测和启停动作。

Aiming to achieve operation area and boundary recognition, operation area real-time automatic measurement and data collection on rice transplanter, an automatic measurement system of working area used in rice transplanter had been designed.The system was composed of the central processing module, the sensors detecting module, the GPS positioning module, the wireless data transmission module, the U disk data storage module, the power supply module and the upper-computer controlling module.The central processing module, using MCU STC12C5A60S2, collected and processed data from GPS positioning module and sensor detecting module,and completed automatic calculation of transplanter working area by analyzing the GPS positioning information. The wireless data transmission module was used for communication with the upper-computer controlling module, which was connected to the host computer via GPRS network technology.And it can realize remote controlling start and stop action on rice transplanter. The result of the experiment showed that the automatic measurement of rice transplanter working area and start and stop action could be remote completed and remote drived by the system.
