摘 要: 研究设计了由发红外光二极管、凸透镜、PD-0120A型硅光电池裸片组组成的无盲区检测精密排种器性能的传感器以及以89C51型单片机为核心控制部件的硬件系统和软件系统。通过传感器检测、人工检测对比试验证明了该无盲区传感器可准确地检测精密排种器的各项性能指标。 In this research, a no-blind area sensor composed of infrared emission diode, convex lens and nude silicon-photocells for precisely detecting the function of a precision seed-metering device and hardware and software systems controlled by 89C51 was designed. To test the function of the senor, we analyzed the experiment data between sensor-detection and man-detection. The experiment results showed that the no-blind area sensor can meter all kinds of function of the seed drill effectively.
