摘要
鉴于高速公路上汽车追尾碰撞事故比例日渐增的状况,汽车防撞系统的研究越来越受到重视。通过针对追尾交通事故分析,主要涵盖由于驾驶员未能专心或疲劳驾驶导致不能与前车保持安全车距的两种主要原因。从安全评价的角度进行研究,结合国内外定点检测技术的发展,设计出了基于环形线圈检测的汽车防撞系统,在事故多发地点设置若干检测线圈,线圈检测出来的数据通过无线传感设备上传至数据库,导入安全距离公式后,当得到的数据小于安全距离的时候,路旁红色闪灯打开对驾驶员予以警告。随着环形线圈检测技术的广泛应用,记录在数据库的数据可广泛用于交通调查,事故判断等。
In view of the increasing proportion of car rear-end collision accidents on expressways,research on car collision avoidance systems has received increasing attention.Through the analysis of rear-end traffic accidents, it mainly covers two main reasons why the driver cannot maintain a safety distance from the preceding vehicle due to the driver's failure to concentrate or fatigue. From the perspective of safety evaluation, combined with the development of fixed-point detection technology at home and abroad, this paper designs a car anti-collision system based on toroidal coil detection. Several detection coils are set in the accident-prone location, and the data detected by the coil is uploaded by the wireless sensor device. To the database, after importing the safety distance formula, when the obtained data is less than the safety distance, the roadside red flashing light turns on to warn the driver. With the wide application of toroidal coil detection technology, data recorded in the database can be widely used for traffic investigation, accident judgment, and the like.
