基于物联网的家用汽车安防装置设计

Design of Security Device for Household Vehicle Based on Internet of Things

家用汽车安防装置可以对密闭的家用汽车内的温湿度进行检测,并可对危险数值进行报警。装置的硬件组成以单片机为核心,包括温湿度检测部分、报警器、显示器及控制部分;利用无线网络进行信息传递;软件部分包括温湿度上限设置、温湿度采集、处理、显示、报警及向车主拨打手机报警等程序。实现对汽车内温湿度实时检测,并显示;车内有人时,当温度达到设置的上限温度时,报警器响报警,通过无线网络将报警信息发到车主的手机上,同时将车窗打开通风,防止滞留在车内人员发生中暑。

A security device for household vehicle can measure temperature and humidity in a closed car,and launch alarm at the critical value.The core of the hardware is a single-chip microcomputer including detection units for temperature and humidity,an alarm,a display and a control unit.The information is transmitted by a wireless network.The software contains setting upper limits of temperature and humidity,data collection of temperature and humidity,display,alert as well as report to the car owner.With all these hardware and software,the temperature and humidity can be monitored and exhibited in real-time.For example,if a person is in the car,the alarm can be launched and reported to the car owner by the wireless network as soon as the temperature reaches to the upper limit.In the meantime,car windows can be opened to prevent the person from heatstroke.
