室内用电离家模式智能控制装置的设计与实现*

摘要

An intelligent control device for indoor power consumption in a “leaving home” mode is designed herein to reduce power waste of home appliances in a standby mode. When nobody is at home, the “leaving home” mode will automatically start to cut off the power supply; otherwise, the“coming home” mode will automatically start to restore the power supply; and the remote control is also supported. The realization scheme of the device is elaborated and corresponding software and hardware design is presented. Furthermore, the personnel detecting algorithm integrating personnel counting and pyroelectric infrared sensor information data is introduced to improve the detection accuracy.%　　针对家用电器待机电能浪费的问题，设计了一种室内用电离家模式智能控制装置，判断室内无人时，自动进入离家模式，切断供电电源；有人时进入居家模式自动恢复供电；支持远程控制。阐述了该装置的实现方案，给出了装置的硬件、软件设计，特别是提出了基于人员计数和热释电红外人体传感器信息数据融合的人员检测算法，提高了人员检测精度。
