异构网络高速公路的事故感知与报警方法

Freeway Accident Detection and Alarm Method Based on Heterogeneous Network

设计了一种基于异构网络的高速公路事故报警系统。基于该系统，提出了一种高速公路事故感知方法，并设计了异构硬件网络、交互通信协议和事故感知策略。通过设定不同的事故场景，用实验对事故感知方法进行了验证。结果表明，设计的交通事故感知方法实现了对按键报警信息、节点故障信息和总线异常信息的正确判断。

In the paper,a freeway accident alarm system based on heterogeneous network is designed.Based on the system, a method of sensing freeway accident is proposed.And the heterogeneous network,the interactive communication protocol and the accident detection method are designed.By setting different accident scenarios, the realization of the method is verified.The experiment results show that the design of traffic accident detection method can realize the correct judgment of button alarm information, node fault information and bus abnormal information.
