无线传感器通常长期在野外工作,其电源能耗一直是受业界关注的技术问题.针对采用低压锂电池供电的无线传感器,提出采用多级多路径控制的电源管理方法,实现超低压降、电源超低功耗和大电流输出.采用本电源管理方法的无线传感器不仅能充分利用电池电能量,还能兼容多种供电电源(如锂电池、锂亚电池、干电池、铅酸电池等)的应用场景.%Wireless sensors usually work in the field for a long time,whose power consumption has always been a technical problem concemed by the industry.A power supply management method based on multi-level multipath control for wireless sensor powered by low voltage lithium battery was proposed,which can achieve ultralow voltage drop,low power consumption and high current output.The wireless sensor that adopts the power management method can not only make full use of the battery energy,but also be compatible with a variety of power supply (such as lithium batteries,lithium-thionyl chloride(Li/SOCl2) batteries,dry batteries,lead-acid batteries,etc.).
