摘要
为更好地保障车内滞留儿童的生命安全,设计了一套用于监测车厢内部生命的系统,采用STM32F407ZGT6作为主控制器,使用温湿度、CO_(2)浓度传感器和视觉检测模块对车厢内环境状况监测、采集;通过NB-IoT物联网通信模块实现数据传输,同时触发系统做出保护动作并发出报警信息。自主搭建简易试验装置,进行系统测试。结果表明:一旦检测到人像,且车厢内温湿度和CO_(2)浓度达到设定阈值,系统即自动做出安全保护动作,同时发出报警信息以提醒用户。研究表明,此设计具有一定的合理性和可行性,可为样机实际应用提供依据。
To protect the life safety of children left behind in the vehicle,a set of system for monitoring the vehicle indoor life was designed.Taking STM32 core board as the controller,several kinds of sensors probing temperature,humidity and gas density and visual detection module were used to monitor and collect the interior parameters of vehicle.The collection parameters were converted and transmitted by NB-IoT,and then the system was triggered to make protection actions and issue alarm information.A simple test device for vehicle indoor life monitoring system is established and the test is obtained.The results show that the sys⁃tem will automatically make protection actions and send alarm information to remind once human image is detected while tem⁃perature,humidity and carbon dioxide concentration in the carriage reaching the preset threshold.It can be concluded that the design and device is reasonable and feasible,which can provide some basis for the application of physical prototype.
