摘要
由于传统系统存在不能实时采集车辆之间的距离、机动车驾驶安全系数较低的问题,为了提高机动车驾驶安全,设计了一种基于激光传感器的车辆安全距离自主预警系统。根据不同驾驶者的驾驶特征,设计了系统的硬件部分。将激光传感器中的数据图像处理芯片作为系统的核心处理器,设计了相应的速度采集模块、语音报警模块,利用CCS对系统进行编程。系统的软件部分以ARM芯片作为核心单元,对天气状况以及道路状况进行实时采集。利用GPS获取驾驶车辆的位置信息,通过GPRS将车辆位置信息发送至系统服务中心。利用系统的服务中心对数据进行分析及处理,并将车辆所对应的相关道路信息发送至车载主控制器。系统中的主控制器对采集模块采集到相关信息进行综合处理,通过处理结果对车辆的安全状况进行判断,针对不同的情况发出不同的预警信息。实验结果表明,所设计系统能够有效减少交通事故的发生,更大程度地提高了驾驶员的安全。
Because the traditional system can not collect the distance between vehicles in real time, the safety of motor vehicle driving is poor. In order to improve the driving safety of motor vehicles, a self-warning system for vehi cle safety distance based on laser sensor is designed. According to the driving characteristics of different drivers, the hardware part of the system is designed. The data image processing chip in the laser sensor is used as the core proces sor of the system, and the corresponding speed acquisition module and voice alarm module are designed. The system is programmed by CCS. The software part of the system uses the ARM chip as the core unit to collect real-time weather conditions and road conditions. The position information of the driving vehicle is obtained byGPS, and the vehicle po sition information is transmitted to the system service center through GPRS. The system is analyzed and processed by the service center of the system, and relevant road information corresponding to the vehicle is transmitted to the vehicle main controller. The main controller in the system comprehensively processes the relevant information collected by the acquisition module, judges the safety status of the vehicle through the processing result, and issues different warning information for different situations. The experimental results show that the designed system can effectively reduce the occurrence of traffic accidents and improve the safety of drivers.
