摘 要
车辆胎压监测在现代汽车工业中具有重要的意义。正常的胎压是确保车辆安全和性能的关键因素之一。胎压不足或异常可能导致事故风险增加、燃油效率下降以及轮胎寿命缩短。因此，对车辆胎压的实时监测变得至关重要。本文介绍了一种基于单片机的车辆胎压监测蓝牙传输系统的设计，包括从机和主机两部分的功能。从机的主要功能是通过胎压检测模块检测车辆的胎压值，并通过DS18B20传感器检测车辆的温度值。随后，从机利用蓝牙技术将这些检测数据传输到主机端，以供进一步处理和显示。主机端的功能包括通过蓝牙接收从机端传来的胎压值和温度值，并在检测到胎压值或温度值超出事先设置的上下限时，触发声光报警以提醒驾驶员。此外，主机还提供了设置汽车胎压和温度上下限值的按键操作，以满足不同车辆和需求的要求。最后，通过LCD1602液晶屏显示车辆的胎压和温度，使驾驶员能够实时监测车辆状态。本设计为车辆胎压监测系统提供了一种便捷、实用和可靠的解决方案，有望提高行车安全性和驾驶舒适性。这一系统在车辆胎压和温度监测方面具有广泛的应用前景，有望在汽车行业得到广泛推广和采用。

Abstract
Vehicle tire pressure monitoring is of great significance in the modern automotive industry. Normal tire pressure is one of the key factors in ensuring vehicle safety and performance. Insufficient or abnormal tire pressure can lead to increased accident risks, reduced fuel efficiency, and shortened tire lifespan. Therefore, real-time monitoring of vehicle tire pressure has become crucial. This paper introduces the design of a Bluetooth transmission system for vehicle tire pressure monitoring based on a microcontroller, which includes the functions of the slave unit and the master unit.
The primary function of the slave unit is to detect the vehicle’s tire pressure using a tire pressure detection module and measure the vehicle’s temperature using a DS18B20 sensor. Subsequently, the slave unit utilizes Bluetooth technology to transmit this collected data to the master unit for further processing and display. The master unit’s functions include receiving the tire pressure and temperature values sent by the slave unit via Bluetooth, and triggering audio and visual alarms when the tire pressure or temperature values exceed predefined upper and lower limits to alert the driver.Furthermore, the master unit provides buttons for setting upper and lower limits for vehicle tire pressure and temperature to cater to various vehicle types and requirements. Finally, it displays the vehicle’s tire pressure and temperature on an LCD1602 screen, allowing the driver to monitor the vehicle’s status in real time. This design offers a convenient, practical, and reliable solution for vehicle tire pressure monitoring systems, with the potential to enhance driving safety and comfort. This system has a wide range of applications in the monitoring of tire pressure and temperature, making it a candidate for broad adoption in the automotive industry.
