技术领域Technical field
本申请涉及高速公路上防止连环撞车预警系统,属于交通控制系统技术领域。The present application relates to an early warning system for preventing serial collision on a highway, and belongs to the technical field of traffic control systems.
背景技术Background technique
目前,国家高速公路里程已达13.1万公里,机动车拥有量2.85亿辆,汽车驾驶员2.96亿人。由于天气、路况、车况以及驾驶员的专业水平与疲劳因素引起的高速公路事故所引起的死亡数和经济损失惊人。而多数重特大事故又是经过连环撞车后造成的,“纵观近几年来全国发生的重特大交通事故,由于一次死亡人数高达10至30多人,其惨烈的事故场景和巨大的生命财产损失,无不在社会上引起强烈反响,也不断引起各界有识之士的高度关注。以2005年为例,全国共发生道路交通事故450254起,死亡98738人,伤469911人,直接财产损失18.8亿元。其中重特大交通事故47起,死亡807人,伤705人。一次死亡10至19人34起,死446人,伤531人;20至29人11起,死275人,伤134人;30人以上2起,死86人,伤40人。”道路交通事故的频繁发生,是经济社会高速发展带来的副作用,从某种意义上来说是不以人的意志为转移的。但这并不是说交通事故就无法避免。据有关媒体报道,“世界上最安全的道路在英国,英国的道路交通安全设施最完备最发达,同时,英国人有着良好的遵守交通法规的习惯,因而道路交通事故发生率最低。”但即便在最安全的英国,也没有高速防连撞预警系统。面对这样一个各国都十分关注的世界性难题,我们仍然可以从对重特大交通事故的个案分析,来总结经验和教训。中国居高不下的交通事故死亡率令道路安全设施面临升级的迫切需求。因此,解决高速公路上发生事故后及时预警的问题迫在眉睫。At present, the national highway mileage has reached 131,000 kilometers, the number of motor vehicles is 285 million, and the number of motorists is 296 million. The number of deaths and economic losses caused by highway accidents caused by weather, road conditions, car conditions, and driver's professional level and fatigue factors are alarming. Most of the major accidents were caused by serial crashes. "Overview of the serious traffic accidents that have occurred in the country in recent years, due to the death toll of more than 10 to 30 people, their tragic accident scenes and huge loss of life and property. In the society, it has caused strong repercussions, and it has also attracted the attention of people of insight from all walks of life. Taking 2005 as an example, there were 450,254 road traffic accidents in the country, 98,738 people died, 469,911 people were injured, and direct property losses were 1.88 billion yuan. Among them, 47 heavy traffic accidents, 807 deaths and 705 injuries. One death was 10 to 19 people, 34 deaths, 446 deaths, 531 injuries; 20 to 29 people, 11 deaths, 275 deaths, 134 injuries; 30 There are 2 people, more than 86 people, and 40 people injured." The frequent occurrence of road traffic accidents is a side effect brought about by the rapid development of the economy and society. In a sense, it is not transferred by human will. But this is not to say that traffic accidents cannot be avoided. According to relevant media reports, “The safest road in the world is in the UK. The road safety facilities in the UK are the most complete and developed. At the same time, the British have a good habit of obeying traffic regulations, and thus the road traffic accident rate is the lowest.” But even In the safest UK, there is no high-speed anti-collision warning system. In the face of such a worldwide problem that all countries are very concerned about, we can still sum up experience and lessons from case analysis of heavy traffic accidents. China’s high traffic accident death rate has placed an urgent need for road safety facilities to upgrade. Therefore, it is extremely urgent to solve the problem of timely warning after an accident on the expressway.
现有的技术多见车载监控系统。通过车载传感,获得车身的速度和重量信息、车辆与周边障碍物的距离并且获得驾驶员面部特征,将获得的速度、重量、距离和面部特征信息与设定的对应阈值进行比较,然后给出相应的提示或向驾驶员发出道路偏离与碰撞预警。现有的技术是对行驶车辆本身信息的采集分析处理,是对车祸可能发生的一种提示,但无法完成车祸发生后对车祸现场信息的采集,更无法向高速交管中心发送信息并对后续跟进车辆发出预警。The existing technology is more common in the vehicle monitoring system. Through vehicle sensing, the speed and weight information of the vehicle body, the distance between the vehicle and the surrounding obstacles are obtained, and the driver's facial features are obtained, and the obtained speed, weight, distance and facial feature information are compared with the set corresponding threshold values, and then given Give a corresponding prompt or issue a road deviation and collision warning to the driver. The existing technology is the collection and analysis of the information of the vehicle itself. It is a kind of warning that a car accident may occur, but it cannot collect the information of the scene of the accident after the accident, and it is impossible to send information to the high-speed traffic control center and follow up. Enter the vehicle to issue an early warning.

The vehicle anti-collision alarm system includes an in-vehicle processing unit and an in-vehicle data acquisition unit connected to the in-vehicle processing unit, a car sound, a car navigation unit, and vehicle communication. The unit, the in-vehicle processing unit is connected to the remote monitoring unit through the in-vehicle communication unit, the in-vehicle communication unit adopts wireless communication or satellite communication, and the in-vehicle data collection unit includes an ultrasonic ranging sensor and a collision sensor disposed on the vehicle, and the ultrasonic ranging sensor is configured to detect The distance from the preceding vehicle promptly reminds the driver to avoid. If the avoidance is not timely, the vehicle collision intensity signal detected by the collision sensor is the signal input device in the vehicle alarm system, and the collision sensor will detect the vehicle collision intensity signal. Passed to the microprocessor, the microcontroller determines whether to send an accident signal to the satellite according to the vehicle collision strength signal detected by the collision sensor. When the signal detected by the collision sensor exceeds the threshold, the microprocessor combines the vehicle with the received accident signal. The navigation unit determines the location of the accident point, and the microprocessor pushes the accident point information to the high-speed traffic control center through satellite communication to start the subsequent value-added service, and the controller II determines that the accident point is output to the warning light, the warning sign and the electronic device connected thereto. The display screen is activated by the controller II to activate at least 5 to 10 kilometers of warning lights and warning signs to alert and display the graphic warning function through the electronic display. The application of the system can greatly reduce the occurrence of highway accidents. .
