汽车智能透气功能之硬件电路设计

Circuit Design in Automobile Intelligent Ventilation Function

本文介绍了以单片机为核心的新型汽车智能透气功能电路。该电路能够自动探测车内温度以及是否有人在车内,如车内有人并且车内温度达到设定值,则该电路自动控制车辆两侧后窗玻璃自动下降10厘米,进行通风透气,从而保护车内的儿童安全。用红外线传感器检测车内是否有人,并采用自动断开电源进行双重安全保护。目前的汽车没有此功能,它的智能程度高,同时具有定时、自动断电保护等功能。通过本研究以期为汽车安全设计提供一定的实用参考价值。

This paper introduces the circuit design in a new type of automobile intelligent ventilation function based on single chip microcomputer.The infrared sensor is used in this circuit to detect the temperature inside the car so as to decide if there are people in the car,and then the circuit will automatically control the rear window glass on both sides to automatically drop by 10 cm for ventilation.The circuit is very intelligent,and has timing and automatic power-off protection function.
