横风公路行车安全引导系统
|
摘要
公路上横风由于其突发性和隐蔽性,对车辆行车安全性有较大影响,对大、中型客车等厢式车辆影响尤为突出,常导致重大恶性交通事故。目前国内在横风多发路段并无完备的横风预警与控制方面的智能设备,仅仅通过设置橫风标志牌以警示驾驶人,无法满足车辆在横风天气下的安全行驶。本研究以横风公路行车安全限速模型为基础,建立一个通过风速、风向传感器等实时测量和数据采集,经Zigbee通信传输至中心ARM处理器进行分析处理,再由可变信息板等组成的发布模块对结果进行发布的横风公路行车安全引导系统,以提高公路车辆在横风气象条件下的安全性。从实际应用角度出发,建立的公路横风的安全引导系统,具有价格低廉、智能灵敏特性,拥有良好的系统扩展性和市场推广性。
The crosswind on highways has great impact on the safety of vehicle driving and usually leads to major malignant traffic accidents due to its suddenness and concealment,especially for the large and medium-sized passenger vans. At present,there isn't any complete warning and control intelligent devices on the crosswind-prone sections in the domestic,and only some crosswind warning signs are set,which cannot meet the safety requirement of vehicle in crosswind weather. The research was carried out based on the speed limit model of vehicle safety on crosswind highways. In this model,several sensors were set up to acquire the data of wind speed and wind direction by real-time measurement and transmit them to ARM to get further analysis by Zigbee. Then,the analytical results were displayed on a deployment module that consists of variable message signs. By applying this model,we can achieve greater safety when driving on highways in crosswind weather condition. In this paper,a complete safety guidance system is established for crowsswind on highway from the perspective of practical application. And the system is low cost,intelligent sensitive,working normally under night and different weather conditions. So it has good system expansibility and market extension.
