摘　　要：本设计以单片机为控制核心,以汽车内部温度为控制对象,通过温度传感器采集温度,经A/D转换器将温度转换成数字信号,当驾驶员按动汽车钥匙时,单片机将转换的数字信号在极短的时间内与事先设定的目标温度进行校对,当温度高于或低于设定的温度时,单片机会控制温度控制组件将温度调节在设定温度以内,从而达到舒适性的要求。本设计的主要特点是在外部中断发生时可以自动关闭程序。当汽车内部温度达到设定值时,会进行相应的提示。本设计具有抗干扰能力强、可靠性高、简单易用、通用性强等特点。其设计方法和实现方案对其它基于单片机的系统设计具有一定的参考价值。This design uses a single-chip microcontroller as the control core,and the temperature inside the car as the control object.The temperature is collected through the temperature sensor and converted into a digital signal by the A/D converter.When the driver turns the car key,the single-chip microcontroller compares the converted digital signal with the pre-set target temperature within a very short time.When the temperature is higher or lower than the set temperature,the single-chip microcontroller will control the temperature control component to adjust the temperature within the set temperature,thereby achieving comfort requirements.The main feature of this design is that the program can be automatically closed when an external interrupt occurs.When the temperature inside the car reaches the set value,corresponding prompts will be given.This design has the characteristics of simplicity,high reliability,strong universality,strong anti-interference ability,and high control accuracy.Its design method and implementation plan have certain reference value for other single-chip microcontroller-based system designs.
