摘要
为避免在使用红外辐射电暖器时的疏忽大意,及时预防火灾事故,设计了一种基于单片机的红外辐射电暖器智能控制系统。该控制系统采用AT89C51单片机作为核心部件,利用热释电红外传感器检测人体信号,利用三极管和继电器来构成断电自锁电路。智能控制系统根据相应情况,可以实现手动定时、关机提示、电源接通提示、延时关机等操作处理。程序采用C语言编写,采用模块化结构设计,条理清晰、通用性好。经过实验验证,系统控制方便、可靠性高、针对性强,能实际实现安全节能的目的。
To avoid negligence in the use of infrared radiation heater, the paper designs infrared heater intelligent control system based on single chip microcontroller to prevent fire accidents timely. This control system takes AT89C51 microcon- troller as the core components, uses the pyroeleetric infrared sensors to detect body signals, and uses transistors and relays to constitute a self - locking circuit, and thus achieves manual timing, shutdown notice, power - on tips and delayshut - down operations on the appropriate circumstances. Programs are written using C language with the modular design, well - organized and good generality. Experimental results show that the system, with high reliability, is not only easy to control, but can actually achieve the purpose of safety and energy saving.
