摘 要: 现有的智能家居中的阀门或者开关一般用的是手动遥控,虽然可以远程操控,但是依旧摆脱不了对多种开关繁琐的操作。为了克服以上缺点,在无线网络环境下开发了一个根据家中人数情况自动运行的智能开关控制系统。系统硬件由主控板、发射板、接收板、驱动板、人体检测装置、无线收发装置和开关器件驱动装置等组成。在主控板的单片机中烧录控制程序系统就可以投入运行。该系统利用抗干扰激光技术自动统计进出大门的人数,实现根据人数情况自动开合开关的功能,在测试实验中连续运行30个小时后,运行稳定,误码率低。该系统解决了智能家居的开关智能控制问题,具有安全、高效的优点。

Abstract: The remote manual control is generally used for valve or switch in the smart home. Although they can be controlled remotely, people still cant operate them in a easy way. An intelligent switch control system was developed in wireless network, which can operate automatically according to the number of people at home. The system consists of the main control board, emission board, receiving board, driver board, human body detection device, wireless transceiver and switch drive device. This system can be put into operation after burning the control program to the micro control unit (MCU). The anti?interference laser technology is used in the system to count the number of people in and out of the door to realize the functions of automatically turning?on or ?off the switch according to the number of people at home. It had low error rate worked stable in a test of 30 h. This system solved the on?off intelligent control problem of the smart home. It is safe and efficient.

随着科技的发展,与智能家居相关的设备逐渐走入了人们的家中。南京物联传感技术有限公司提出的自我搭建智能家居的平台,使得手动搭建智能家居变成可能[1];海尔推出的智能云家电,实现了家电终端生产与智能家居平台的结合[2]。这些产品的优点在于实现了家居生活的智能和远程控制,但是目前很少有商家能考虑到家中开关的智能控制,开关的智能控制能从源头上解决安防问题,并且更加稳定。
现代家庭中的阀门和开关的控制至关重要,大量媒体报道过由于电源没有关闭造成的漏电和火灾,或者冬天出门时候由于忘记关闭阀门而造成的水管破裂[3]。……
