Design and Experimental Investigation of Vehicle Indoor Life Monitoring System
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.
