摘　　要：微系统技术集信息获取、处理、交换、执行以及供能等功能于一体,已广泛应用于物联网终端,而物联网终端电池续航能力限制了其在各类场景中的应用能力。将自唤醒技术--一种能量管理策略--应用于物联网终端微系统,可实现微系统低功耗休眠与唤醒状态的自动切换。对微系统的自唤醒技术进行归纳与分析,根据微系统休眠时功耗特点的不同,将自唤醒技术分为四类。然后在此基础上,对微系统自唤醒技术主要应用场景中有效工作时长占比小、分布范围广、部署数量多等特点进行了分析。最后对微系统自唤醒技术未来发展与面临挑战的讨论表明,自唤醒技术在未来物联网的构建过程中将发挥重要作用。Microsystem technology integrates the functions of information acquisition,processing,exchange,execution and power supply,which has been widely used in the terminal of the Internet of Things(IoT).Many IoT terminals'battery endurance limits its application ability in various scenarios.Passive wake-up technology is a kind of energy management strategy,which is applied in the microsystem of IoT terminals,and can realize the automatic switch between low-power sleep state and wake working state.In this paper,the passive wake-up technology of microsystems is reviewed and summarized.According to the different power consumption characteristics of microsystems during sleep state,the passive wake-up technology is divided into four categories.The main application scenarios of microsystem passive wake-up technology are introduced.The scenarios usually have the characteristics of small proportion of effective working time,wide distribution range and large number of deployments.Finally,the future development and challenges of microsystem passive wake-up technology are discussed.In the future construction of the IoT,passive wake-up technology will further play an important role.
