摘　　要：为解决城市道路车辆越线违章问题,设计研究了1种嵌入于道路表面的车辆越线警示装置.根据装置结构简单、成本低、智能化和适用于各种路段的原则,设计了警示装置总体方案,分析了装置工作过程的原理,并对装置信息采集模块、视觉与听觉警示模块、电源模块和控制系统模块的软硬件进行了设计和介绍.此装置通过薄膜式压力传感器内部的压敏电阻阻值的变化来检测是否有车辆发生压线行为,并将数据发送到单片机进行读取并处理,单片机采集到这种信号后,控制相应的IO接口,使控制LED灯带和蜂鸣器的开关闭合,此时LED灯带和蜂鸣器会同时启动,一直到违章驾驶员行驶至正常车道,该警示装置才会停止响应.该装置结构轻巧便携、易于装卸、成本低、适用于各种路段,推广嵌入于道路表面的车辆越线警示装置,对治理城市越线违章行为和改善城市道路交通情况有一定的促进作用.In order to solve the problem of illegal vehicles crossing the solid lane line on urban roads,a vehicle crossing warning device embedded in the road surface is designed and studied.According to the principles of simple structure,low cost,intelligence and applicability to various road sections,the overall scheme of the warning device is designed,the principle of the working process of the device is analyzed,and the device information collection module,visual and auditory warning module,power supply module and the software and hardware of the control system module are designed and introduced.This device detects whether there is a line-pressing behavior of the vehicle through the change of the piezoresistor resistance inside the thin-film pressure sensor,and sends the data to the single-chip microcomputer for reading and processing.After the single-chip microcomputer collects this signal,it controls the corresponding IO.The interface makes the switch that controls the LED light strip and the buzzer close,and the LED light strip and the buzzer will start at the same time,and the warning device will not stop responding until the violating driver returns to the normal lane.The device is light and portable in structure,easy to load and disassemble,low in cost,and is suitable for various road sections.The promotion of vehicle line crossing warning devices embedded in the road surface will have a certain effect on the control of urban line crossing violations and the improvement of urban road traffic conditions.
