基于双激光源的水田作业机械导航定位系统电路设计

Circuit Design of Navigation and Localization System of Paddy Field Working Machine based on Double Laser Source

为实现对水田作业机械导航定位系统提供准确的位置坐标、航向角、前轮转角、行驶速度等重要信息参数,并完成相应的控制动作,设计了一套基于双激光源的水田作业机械导航定位系统电路。该系统电路主要由激光发射电路、激光接收电路和中央处理单元组成。试验结果表明,该导航定位系统效果较好,能满足作业速度低于1.5 m/s的水田作业机械导航定位系统的要求。

In order to provide some important information including accurate position, heading angle, front wheel steering angle and speed and to complete the corresponding control action for the navigation and localization system of the paddy field working machine, the circuit of navigation and localization system of paddy field working machine based on double laser source was designed. The circuit of the system was composed of the laser transmitter, receiver, and the central processing unit. The field experiment showed that the navigation and localization system was better able to complete the requirements of field operations, when the speed of paddy field working machine was lower than 1.5 m / s.
