The invention discloses an STM32 chip-based parking space warning system and method for an electric vehicle charging pile, and belongs to the field of vehicle parking safety. The invention designs an STM32 chip-based parking space warning system for an electric vehicle charging pile, aiming at the situation that an electric vehicle needing to be charged cannot be charged due to the fact that a parking space of the electric vehicle charging pile is occupied. When the automobile is driven into the parking space, whether the license plate of the parked automobile is green or not is recognized through the OPENMV module, and whether the charging pile is in operation or not is judged through the current sampling circuit; and if any one of the information does not accord with the information of the parking lot, the buzzer continuously gives an alarm, a corresponding warning slogan appears on the display screen, and the GPS module and the ESP8266 communication module are started at the same time to prompt the vehicle owner of the corresponding information of the nearest parking lot. Through the license plate recognition function and the charging detection function, the situation of the automobile entering the parking space of the charging pile is analyzed from multiple angles, the system gives an alarm and guides the automobile to a place where the automobile can be parked at the same time, and it is fully guaranteed that the parking space of the charging pile is not occupied.
一种基于STM32芯片的电动汽车充电桩车位警示系统及方法,属于汽车停车安全领域。针对电动汽车充电桩车位被霸占而导致需要充电的电动汽车无法充电的情况,本发明设计了一种基于STM32芯片的电动汽车充电桩车位警示系统。当汽车驶进车位时,通过OPENMV模块识别停入车辆车牌是否有绿色,以及通过电流采样电路判断充电桩是否在运行;若是任意一项不符合,则蜂鸣器持续发出警报,并且显示屏上会出现相应的警示标语,且同时GPS模块与ESP8266通信模块启动,为车主提示最近停车场的相应信息。本发明通过车牌识别功能和检测充电功能,多角度分析了进入充电桩车位的汽车情况,且系统发出警示的同时,也引导他们前往能够停车的地方,充分保障了充电桩车位不被占用。
