基于STM32的儿童安全座椅防遗忘检测报警系统
|
摘要
本文提出了一种基于电容传感器的儿童安全座椅防遗忘检测方法,与传统的检测方法相比,该检测方法具有准确、可靠且易于安装等优点,且在儿童防遗忘检测功能的基础上加入了车辆发动机启停检测装置、车内环境检测装置和报警装置。发动机启停装置可以将发动机状态利用蓝牙模块发送到MCU,MCU可根据发动机的状态有效地提醒车主不要将儿童遗忘在车内,同时利用车内环境检测装置对车内环境进行实时监测,当车内环境恶化且危害到儿童的生命时,可以利用GSM模块及时提醒车主。
This paper proposes a method for anti-forgetting detection of child safety seat based on capacitive sensor. Compared with the traditional detection method,this detection method has the advantages of accuracy,reliability and being easy to install,and based on children prevent forgotten detection function joins the vehicle engine start-stop detection device,interior environment detection device and alarm device. Engine start-stop engine condition using Bluetooth module can be sent to the MCU. The MCU can effectively remind the owner not to forget the child in the car according to the state of the engine,at the same time use the interior environment detection device for real-time monitoring of interior environment. When the car environmental degradation could be harmful to children's life,timely reminding the owner could use the GSM module.
