摘要
利用红外遥控专用芯片PT2262与PT2272,围绕51单片机搭建简单可行的红外控制电路,并提出了经济方便的PWM电机驱动电路,结合揉性带式底盘设计了红外遥控小车。通过对电磁阀电压控制特性的分析提出了PWM控制电路,并结合红外传感器建立了自动喷雾系统。
The article makes use of the infrared ray telecontrolled appropriation chip PT2262 and PT2272s around 51MCU to build the simplely appropriate electric circuit controlled by infrared ray, and put forward the economic convenient electric circuit of PWM to drive the engineering, combining to crumpling resistance belt chassis designed the small car telecontrolled by infrared ray. Analysis the characteristic or the electromagnetism valve voltage and put forward the PWM control electric circuit, and combined the infrared ray sensor to build up spray automatically system.
