Abstract: The original intention of this project is to reduce the occurrence of traffic accidents and save the lives of children stranded in the car. It designs and implements an intelligent monitoring system for car movement safety to add a guarantee for life safety. The system used a three-tier architecture of front-end acquisition equipment, Alibaba cloud platform and mobile APP, and was based on AI facial expression recognition technology, alcohol detection sensors, and air quality detection sensors to achieve cloud remote control of drunk driving, fatigued driving, and children stranded in the car. The system set up a multi-level early warning and emergency control mechanism to realize the intelligent monitoring of vehicle safety and prevent accidents.
