防碰撞系统设计功能


 本文设计的基于μC/OS-Ⅱ的嵌入式高速公路防碰撞预警系统具有如下功能。首先数字地图和GPS定位导航功能:在本系统设计时为了方便使用车辆在行驶过程提前对本路段到路况有一定的了解,所以系统提供了数字地图。这样可以便于查询和选择合适行车路线。通过将数字地图和GPS定位功能的结合驾驶员可以及时把握自己的行车位置,同时还可以实现一个非常方便的导航功能。其次是路况显示功能:系设计时选用了高清晰的液晶进行路况显示。显示本车行驶路段的数字地图和根据GPS检测的位置信号显示本车在数字地图中的位置。显示功能不仅仅显示本车在数字地图中的位置还可以通过近距离无线通信模块和行驶在本路段的其他车辆进行通信获得周围车辆的位置信号,并显示在数字地图中。这样驾驶员通过显示器可以看到行驶在本路段和自己距离较近的所有车辆之间的相对车距。便于驾驶员实时调节相互之间的车距。再其次车况实时检测功能:系统可以实时检测本车的行驶状况,主要检测本车是否正常行驶还是发生故障停止路上或者发生交通事故停止在路中央。如果发生故障停止在路中间系统将通过GPRS远程通信模块将故障信号和GPS定位信号发送给高速公路管理中心,告知管理中心其发生故障的位置,方便管理中心及时提供援救和处理措施。同时如果检测到故障时还将通过近距离无线通信模块将自己的故障位置发生出去。当行驶在本路段的后面的车辆靠近时会提前收到来自它发出的故障预警无线电信号,从而后面的车辆会提前做好减速和避让措施。当车况检测正常时系统也将会通过近距离无线模块将自动的位置信号发送出去并接收周围车辆发出的位置信号。最后系统还具有路况检测功能:本系统的路况检测方法和以往的各种手段进行测距的路况检测方法不同。本系统设计的路况检测是通过将无线通信技术和GPS定位技术相结合的方法。当两辆车距离靠近时,双方会检测到彼此的无线电信号然后通过无线通信的方式提前获得对方车辆的GPS采集回来的信号,然后通过彼此间的无线通来判断彼此间的距离和分析前面车的行驶状态,是故障停止还是正常行驶。


 


Designed Features of Anti-collision System


The embedded highway vehicle anti-collision forewarning system based on μC/OS-ⅡRTOS, which is designed in this article, boasts of the following functions. Firstly, the digital map and GPS navigation function. In order to provide more convenience for the vehicle with the system can know more about the road surface before the steering, the digital map is offered in the system, which is to speed up the process of looking up or selecting the suitable route. Through the combination of the digital map and the positioning function of GPS, the driver can easily be informed of the concrete location of the vehicle during driving. In addition, the navigation can also be achieved in a rather simple way. Secondly, the display functions of the road condition. The high-definition liquid crystal display is adopted in the system design to clearly illustrate the highway conditions. The digital map displaying the covering routine of the vehicle and the location of the vehicle in the digital map identified through the GPS detection signal can be ascertained. Beside this way, the location signal of the vehicle can also be obtained and displayed in the digital map through the close-distance wireless communication module and the communication with other vehicles running in the surrounding area. In this way, the driver can read the comparative distance between his/her vehicle and other surrounding vehicles or those with the same route, which is easy for the driver to adjust the vehicle distance in a real-timely manner. Third, the real-time detection functions regarding the vehicle conditions. It is mainly for the purpose of detecting the operational status of the system borne vehicle, put it more concretely, to detect whether the vehicle is in the normal operation or has been stopped due to troubles on the road or stopped in the middle of the highway because of the traffic accidents. In the event that the vehicle is stopped due to trouble, the failure signal and GPA positioning signal will be sent to the highway management center through the GPRS long-distance correspondence module to tell it the concrete location of the trouble occurrence so that the highway management center can offer the timely rescue and treatment measures. Meanwhile, the detection of failure can also be followed up by sending the information of failure and location through the close-distance wireless module. When the rear vehicle is approaching the system-borne vehicle, it will receive the trouble precaution signals through wireless communication immediately so that the rear vehicle can get ready for speed reduction or the precautions. In case of the normal operation system of the vehicle, the location can also be sent automatically through the close-distance wireless module functions. Last but not the least, the road surface detection function. The road surface detection methods are different from those previous measurement ways of the road surface condition. The road surface detection designed in this system is achieved through the integration of wireless communication and the GPS positioning technologies. When the two vehicles are too close to each, the wireless communication signals of each vehicle can be detected by each other and the collected signals through the GPS system can also be obtained to judge the distance of each vehicle from another and to analyze the operational status, whether break down for troubles or normal operation, of the vehicles in front.
