摘要
设计了一种基于对射型红外光电传感器和单片机控制的智能烟草定量穴施追肥机。该追肥机在发动机牵引下前进时,先由传感器检测装置中的20对对射型红外光电传感器检测出烟株中心位置和直径,再由单片机决策出最佳追肥点,控制鸭嘴完成自动化定量穴施追肥。试验表明:传感器检测装置检测准确率达99%,追肥准确率达97%,烟苗损伤率小于2%。
A kind of intelligent tobacco quantitative hole application topdressing machine based on opposite-type infrared photoelectric sensor and microcontroller was designed. When the topdressing machine moved forward pulled by the engine, 20 pairs of opposite-type infrared photoelectric sensors of the sensor detection device accurately detected the central position and diameter of the tobacco plant, then the microcontroller determined the best topdressing point and controlled the duckbill to complete the automatic and quantitative hole application topdressing. The test results showed that the detection accuracy rate of sensor detection device reached to 99% , the topdressing accuracy reached to 97% , and the tobacco plant injury rate was less than 2%.
