In order to reduce the harm of accidents to drivers and passengers, the car collision detection system comes into being.This paper designs a car collision detection system based on a microcontroller. The system uses a negative acceleration sensor to monitor the vehicles negative acceleration. When the detected negative acceleration exceeds the preset maximum value, the system controls the airbag deployment via a relay and sends an SMS alarm to the mobile phone through a wireless communication module. Additionally, the negative acceleration threshold can be set via buttons, and the measurement data is displayed in real-time on the screen. The monitoring data is then transmitted to the Alibaba Cloud platform via a wireless network and synchronized to the mobile phone.The system has the characteristics of strong real-time performance, high reliability and easy operation, which can effectively improve the safety protection ability of cars in collision accidents, provide timely early warning and protection for drivers and passengers, and has important practical significance for improving the safety performance of cars and reducing accident casualties.Key words:Car collision detection; microcontroller; negative acceleration; display screen; wireless communication目 录摘 要Abstract1 引言1.1 课题研究的背景和意义1.2 国内外的研究现状1.3 系统总体设计思路1.4 课题研究的主要内容和工作1.5 本章小结2 系统总体设计方案2.1 系统整体结构2.2 方案论证和比较2.2.1 单片机模块方案选型2.2.2 负向加速度检测模块方案选型2.2.3 无线通信模块方案选型2.2.4 显示模块方案选型2.2.5 继电器模块方案选型2.3 本章小结3 系统硬件电路设计3.1 单片机最小系统电路设计3.2 负向加速度检测模块电路设计3.3 无线通信模块电路设计3.4 显示模块电路设计3.5 继电器模块电路设计3.6 按键模块电路设计3.7 本章小结4 系统软件程序设计4.1 编程软件介绍4.2 系统主流程设计4.3 负向加速度检测模块子程序设计4.4 无线通信模块子程序设计4.5 显示模块子程序设计4.6 按键模块子程序设计4.7 本章小结5 实物制作与系统调试5.1 PCB板的制作流程5.2 调试过程5.2.1硬件调试5.2.2软件调试5.2.3 实物测试5.3 实物测试数据分析5.4 本章小结6 结论致 谢参考文献附录1附录2附录3附录4
