基于CAN总线的多功能车辆自动闭锁系统设计

摘要

Based on the purpose of driver's driving safety and vehicle body safety,this paper writes the design of automatic locking system based on CAN bus. The design of integrated detection system of the door,alcohol detection system,front and rear of the vehicle,obstacle detection system and method of CAN bus communication system,and through man- machine interactive information detection to determine whether to give the driver permission to start the car,and the vehicle is locked. Finally, through the physical production.The experimental results show that the system using the alcohol sensor, the ethanol concentration in the blood of the driver flexible detection,using CAN bus communication transceiver module completes the data transmission,has a good human-computer interaction control, realize the automatic locking of the vehicle.%基于驾驶员行车安全与汽车车身安全的目的,本文章攥写了基于CAN总线的多功能车辆自动闭锁系统设计.本设计整合了车门检测系统,酒精检测系统,车前、车后障碍物检测系统,以及CAN总线通讯系统的方法,并通过人机检测信息交互判断是否给驾驶员启动汽车的权限,从而实现车辆自动闭锁.论文最后通过实物制作实验结果表明,该系统利用酒精传感器,灵活的检测驾驶员血液中的乙醇浓度,利用CAN总线通讯收发模块完成了数据的传输,具有良好的人机交互控制方式,实现了车辆的自动闭锁.
