摘要
给出了一种应用于太阳能系列产品的新型人体红外信号探测系统的研制方法,该方法将探测到的人体红外信号进行滤波放大后驱动相应负载工作,同时利用自行研制的芯片IV0201取代LM324组成滤波放大电路并加入IV0103、IV0104两颗智能型电源管理芯片,从而使该系统成功的用在太阳能系列产品,并可满足低成本、高可靠性、低功耗等要求。
A method is proposed for developing an innovative infrared human signal detection system applied in solar energy products. It can detect human infrared signals and enlarge them to drive the load efficiently with an infrared signal filter. By the use of a self-developed chip IV0202 to replace LM324, a new amplified-filter circuit is formed and two intelligent power management chips IV0103 and IV0104 are included in the circuit so as to apply the system to solar en ergy products to satisfy the requirements for low cost, high reliability and low power dissipation.
