摘 要：为了解决大型商场在高峰時期车位紧张、车主进入车库后盲目寻找车位引起交通堵塞以及无法实时统计当天该车位的停车次数等问题，设计了一款基于STM32的智能车位检测系统。该系统以STM32L431RC微控器作为主控芯片，分别采用超声波测距模块作为车位状态检测模块、光电传感器模块进行停车车辆的检测和计数操作、火焰探测传感器模块作为检测车位着火模块、智能路灯模块作为车位的照明模块、有机发光二极管模块作为车位停车次数的显示模块，NB-IoT通信模块将数据传输至车主手机上。该系统实现了车位状态检测、车位停车次数统计和车位着火监控等功能。结果表明，该系统具有实时性、稳定性强等特点，易于实现。

Abstract： In order to solve the problems of shortage of parking spaces in large shopping malls during peak hours， car owners blindly look for parking spaces after entering the garage， causing traffic congestion， vehicle safety hazards caused by parking space fire， and unable to count the parking times of the parking space on the same day in real time.This paper designs an intelligent parking space detection system based on STM32.The system takes STM32L431RC microcontroller as the main control chip， and uses ultrasonic ranging module as the detection module of parking space state，the photoelectric sensor module is used as the detection and counting operation of parking vehicles， flame detection sensor module as the detection module of parking space fire.the intelligent street lamp module is used as the lighting module of the parking space， the OLED module is used as the display module of the parking times of the parking space， and the NB-IoT communication module transmits the data to the owner's mobile phone.The system realizes the functions of parking space state detection， parking number statistics and parking space fire monitoring. The results show that the system has real-time， strong stability and easy to implement.

近些年，随着人们生活水平的大幅提升，私家车数量迅猛增长。在一些大型购物中心，大多数停车场采用人工方式进行车位管理。由于人力资源有限，工作人员无法及时了解停车场内的车位情况，而引起车主不清楚停车场内的车位状态，开车绕库几圈都找不到车位的尴尬局面[1]。为了方便车主及时了解停车场车位使用情况，设计了一款基于STM32的智能车位检测系统。该系统以STM32L431RC微控制器作为主控芯片，配备了超声波测距传感器、NB-IoT通信、火焰探测传感器、车流计数传感器、有机发光二极管（Organic Light-Emitting Diode，OLED）显示屏等一系列模块，能够提高停车场管理人员的工作效率和服务质量，方便车主实时监控车位状态，减少车主停车时间。……
