摘　　要：针对高速公路上事故发生后,后续车辆不能及时了解前方路况而造成的二次事故,结合GPS定位技术和无线通讯技术设计了一套高速公路二次事故预警系统,系统分为事故检测装置和警示灯报警装置。事故检测装置固定在车辆内部(驾驶员可以接触到的位置,且不妨碍驾驶);警示灯报警装置被放置在高速路中央的隔离带上,每隔50 m放置1个。该系统具有反应快、误差小、有效预警等特点,有效解决了在事故地点后方设置路障这个复杂过程,具有很强的实用性。The second accident is caused because the follow-up vehicles cannot understand the road conditions in time after an accident occurs on the highways. For the second accidents,a warning system was designed by combining with GPS positioning technology and wireless communication technology. The system includes an accident detection device and a warning light alarm device. Accident detection device is fixed inside the vehicle( the driver can touch the position and does not hinder driving),the warning light alarm device is placed on the isolation belt in the center of the highway and placed every 50 meters. The experimental results show that the system has the characteristics of normal function,small error,quick response,simple and easy to operate,and effectively solves the complex process of setting up roadblocks behind the accident site,and has a strong practicality.
