基于 STM32F103C8T6 单片机的智能测距报警小车（项目编号：mcuclub-dz-1027），整合了超声波模块 HC-SR04、温度检测模块 DS18B20、按键、OLED 显示屏、蓝牙模块 ECB02、电机驱动模块 SDC9150 及蜂鸣器、红灯，实现了对周围环境的自动化测距、报警、温度监测及远程控制。系统核心功能包括：通过 HC-SR04 获取距离值，根据距离不同（小于 40cm 大于 20cm、小于 20cm），使红灯和蜂鸣器按不同频率工作；通过 DS18B20 检测环境温度，对超声波进行温度补偿，当温度小于 25° 时，红灯和蜂鸣器以每 1/2 秒的频率工作；利用按键可设置距离最大最小值、温度最大值；通过 OLED 显示监测数据及设定的阈值；通过蓝牙模块 ECB02 将数据发送到手机端，手机端可设置阈值并控制小车行驶；通过 SDC9150 驱动小车运行。
该系统的实现，有效提升了移动小车的自动化、智能化水平，通过实时测距、精准报警、温度补偿及远程控制，为小车的安全行驶与便捷操作提供了可靠的技术支持，同时为智能移动设备领域的发展提供了参考，具有较高的实用价值与推广意义。

ABSTRACT
In various scenarios, real-time monitoring of obstacles around mobile carriers, distance warning, and convenient control are of great significance for ensuring mobile safety and operational efficiency. Traditional mobile carrier driving relies heavily on manual observation and control, which has problems such as inaccurate judgment of obstacle distance, untimely danger warning, and inconvenient remote management, making it difficult to meet the needs of modern intelligent movement.
The intelligent ranging and alarm car based on STM32F103C8T6 microcontroller (project number: mcuclub-dz-1027) integrates ultrasonic module HC-SR04, temperature detection module DS18B20, buttons, OLED display, Bluetooth module ECB02, motor driver module SDC9150, buzzer and red light, realizing automatic ranging, alarm, temperature monitoring and remote control of the surrounding environment. The core functions of the system include: obtaining distance values through HC-SR04, and making the red light and buzzer work at different frequencies according to different distances (less than 40cm and more than 20cm, less than 20cm); detecting the ambient temperature through DS18B20 to perform temperature compensation for the ultrasonic wave, and when the temperature is less than 25°, the red light and buzzer work at a frequency of every 1/2 second; using buttons to set the maximum and minimum distance values and maximum temperature value; displaying monitoring data and set thresholds through OLED; sending data to the mobile phone terminal through Bluetooth module ECB02, and the mobile phone terminal can set thresholds and control the car to drive; driving the car to run through SDC9150.
The implementation of this system has effectively improved the automation and intelligence level of the mobile car. Through real-time ranging, accurate alarm, temperature compensation and remote control, it provides reliable technical support for the safe driving and convenient operation of the car. At the same time, it provides a reference for the development of the intelligent mobile equipment field, and has high practical value and promotion significance.
