摘要：随着汽车保有量的不断增加，行车安全问题日益受到关注。轮胎气压异常以及超速行驶是导致交通事故的重要因素之一，为了有效预防交通事故的发生，设计胎压与速度监测系统迫在眉睫
本设计基于STM32F103C8T6单片机，开发了一种汽车胎压与行驶速度监测系统，旨在提升车辆行驶的安全性。系统通过胎压监测模块实时获取轮胎气压数据，当胎压超出预设的最大值或低于最小值时，触发声光报警；通过测速模块监测车辆行驶速度，一旦速度超过设定的最大值，同样启动声光报警。系统通过按键可手动设置胎压和车速阈值，并切换显示界面；通过显示屏实时显示胎压、车速等实时数据。通过蓝牙模块，可将测量数据传输至手机端进行显示，并可通过手机端远程阈值设置和速度切换操作。
实物测试表明，该系统运行稳定，能够准确监测轮胎气压和车速，并在异常情况发生时及时报警，有效提高了行车安全性，为驾驶者提供了可靠的安全保障，具有较高的实用价值和市场推广前景。

Based on the monitoring system for tire pressure and driving speed of automobiles
Abstract：With the continuous increase in car ownership, driving safety issues are receiving increasing attention. Abnormal tire pressure and speeding are important factors leading to traffic accidents. In order to effectively prevent traffic accidents, it is urgent to design a tire pressure and speed monitoring system
This design is based on the STM32F103C8T6 microcontroller and develops a tire pressure and driving speed monitoring system for automobiles, aiming to improve the safety of vehicle operation. The system obtains real-time tire pressure data through the tire pressure monitoring module. When the tire pressure exceeds the preset maximum value or falls below the minimum value, it triggers an audible and visual alarm; Monitor the vehicle’s driving speed through the speed measurement module, and once the speed exceeds the set maximum value, activate the sound and light alarm. The system can manually set tire pressure and vehicle speed thresholds through buttons, and switch display interfaces; Real time data such as tire pressure and vehicle speed are displayed on the screen. Through the Bluetooth module, measurement data can be transmitted to the mobile phone for display, and remote threshold setting and speed switching operations can be performed through the mobile phone.
Physical testing has shown that the system operates stably, accurately monitors tire pressure and vehicle speed, and promptly alarms in case of abnormal situations, effectively improving driving safety and providing reliable safety guarantees for drivers. It has high practical value and market promotion prospects.
