Aiming at potential safety hazards in vehicle driving such as lack of driver identity verification, drunk driving, unfastened seat belts, vehicle overload, abnormal vehicle speed and inability to realize real-time management of driving positions, the traditional vehicle safety monitoring methods have single functions, passive monitoring, lagging early warning, and cannot realize remote real-time monitoring of multi-dimensional driving safety data, which is difficult to meet the needs of intelligent vehicle safety management. This paper designs an intelligent vehicle safety monitoring and remote monitoring system based on STM32F103C8T6 microcontroller. The system integrates multiple core functions including driver identity recognition, alcohol concentration detection, seat belt wearing status monitoring, vehicle load monitoring, vehicle speed dynamic monitoring, GPS positioning, local data display, abnormal sound and light early warning, WiFi remote data transmission and mobile terminal threshold customization. The system relies on the RC522 radio frequency module to realize driver card-swiping identity recognition, and completes vehicle start verification by matching different driver identity permissions. The MQ-3 alcohol sensor is used to collect real-time in-vehicle alcohol concentration, and the vehicle start function is locked and early warning is triggered when the concentration exceeds the standard. Combined with the JS opposite tube to detect the driver’s seat belt wearing state, the KY-003 Hall sensor and MX1508 motor are used to simulate the wheel driving working conditions to real-time monitor abnormal conditions such as unfastened seat belts during driving, sudden speed changes, excessive speed and sudden vehicle stop. The HX711 weighing module is equipped to accurately collect vehicle load data and identify vehicle overload violations. Meanwhile, the ATGM332D-5N GPS module acquires real-time accurate vehicle geographic location information. Equipped with an OLED display screen, the system can locally and real-time display all monitoring data including identity recognition status, alcohol concentration, vehicle load, driving speed and positioning information. It supports users to customize the safety thresholds of vehicle load and alcohol concentration through the mobile terminal. When each monitoring parameter exceeds the preset safety range or there are illegal operations and driving abnormalities, the device will immediately trigger local sound and light alarms, and linkage the mobile terminal to pop up windows and vibrate for remote early warning. The system realizes remote wireless transmission of all monitoring data through the ESP8266 WiFi module, which can be synchronized to the mobile terminal in real time, facilitating managers and drivers to grasp the vehicle driving safety status anytime and anywhere. Integrating multi-dimensional vehicle safety monitoring functions, this system effectively solves the problems of low intelligence, untimely early warning, incomplete management and inability of remote monitoring of traditional vehicle safety monitoring. It realizes the integration of vehicle start permission verification, driver status monitoring, driving condition monitoring, position positioning, intelligent abnormal early warning and remote visual management, greatly improves the intelligence and automation level of vehicle driving safety management, can effectively reduce the incidence of vehicle driving safety accidents, and has high practical application value and promotion significance.
