摘要
在车辆行驶过程中，轮胎的胎压及相关环境参数的稳定对行车安全至关重要。传统的胎压管理多依赖人工检查，存在参数监测不及时、异常处理滞后、远程监控缺失等问题，难以满足现代化车辆智能化安全管理的需求。
基于 STM32F103C8T6 单片机的胎压监测系统（项目编号：mcuclub-dz-1029），整合了 DS18B20 温度传感器、压力检测模块、GPS 模块、按键、OLED 显示屏、4G 模块、喷淋装置、水泵、步进电机及语音提醒装置、LED 灯，实现了对车辆轮胎及相关环境的自动化监测、异常处理及远程管理。系统核心功能包括：通过 DS18B20 监测当前环境温度，当温度大于设置的最大值时，启动喷淋装置并控制水泵抽水降温；通过压力检测模块检测当前胎压，若胎压大于最大值，进行语音提醒并通过步进电机模拟打开放气阀门，同时 LED 灯变红提醒，当气压小于最大值时，关闭放气阀门；通过 GPS 获取当前的定位信息；利用按键可设置各参数阈值并进行相关控制；通过 OLED 显示屏显示各项测量值；通过 4G 模块将检测数据传输到手机端，手机端可远程控制喷淋装置的开启。
该系统的实现，有效提升了胎压监测的自动化、智能化水平，通过实时监测、及时处理异常及远程控制，为车辆的行车安全提供了可靠的技术支持，同时为智能车辆安全监测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
During the operation of a vehicle, the stability of tire pressure and related environmental parameters is crucial to driving safety. Traditional tire pressure management relies heavily on manual inspection, which has problems such as untimely parameter monitoring, delayed abnormal handling, and lack of remote monitoring, making it difficult to meet the needs of modern vehicle intelligent safety management.
The tire pressure monitoring system based on STM32F103C8T6 microcontroller (Project No.: mcuclub-dz-1029) integrates DS18B20 temperature sensor, pressure detection module, GPS module, buttons, OLED display, 4G module, sprinkler device, water pump, stepper motor, voice reminder device and LED lights, realizing automatic monitoring, abnormal handling and remote management of vehicle tires and related environments. The core functions of the system include: monitoring the current ambient temperature through DS18B20, and when the temperature exceeds the set maximum value, starting the sprinkler device and controlling the water pump to pump water for cooling; detecting the current tire pressure through the pressure detection module, if the tire pressure is greater than the maximum value, providing voice reminders and simulating the opening of the deflation valve through the stepper motor, while the LED light turns red for reminder, and closing the deflation valve when the air pressure is less than the maximum value; obtaining current positioning information through GPS; using buttons to set various parameter thresholds and perform related controls; displaying various measured values through the OLED display; transmitting detection data to the mobile phone terminal through the 4G module, and the mobile phone terminal can remotely control the opening of the sprinkler device.
The implementation of this system effectively improves the automation and intelligence level of tire pressure monitoring. Through real-time monitoring, timely handling of abnormalities and remote control, it provides reliable technical support for vehicle driving safety, and also provides a reference for the development of the intelligent vehicle safety monitoring field, with high practical value and promotion significance.
