Description
技术领域technical field
本发明应用于机动车的事故报警监测领域,具体涉及一种车辆事故等级自动识别及监测预警装置、系统及方法。The invention is applied to the field of accident alarm and monitoring of motor vehicles, and in particular relates to a vehicle accident level automatic identification, monitoring and early warning device, system and method.
背景技术Background technique
随着经济的发展,机动车的数量正在急速递增,随之而来的事故数也在有增无减。目前,当机动车事故发生后,特别是在人烟稀少的山区和高速公路的重大事故,交管及救护中心不能第一时间获知事故信息并及时赶到现场,这就给事故认定及伤员救治照成了很大影响。2003-2007年中国道路交通事故统计年报显示90%以上的事故形态为碰撞,且近90%以上的事故伤亡人数都是由于碰撞造成的。来自德国的数据显示约30%的人车祸后并不知道自己身处何处。同时,驾车、弃车逃逸现象时有发生,这就给伤员救援及事故责任认定造成了很大的难处。而当前的车祸自动报警只是在车祸发生后启动GPS定位器和车载电话自动拨打求救电话,并不能将事故信息发送至监管部门;同时,目前车祸自动报警系统也并不能在车祸发生后有效识别驾驶人及车祸中的视频信息。With the development of the economy, the number of motor vehicles is increasing rapidly, and the number of accidents that follow is also increasing. At present, when motor vehicle accidents occur, especially major accidents in sparsely populated mountainous areas and highways, traffic control and ambulance centers cannot be informed of the accident information at the first time and rush to the scene in time, which makes it difficult for accident identification and wounded treatment. big impact. The 2003-2007 China Road Traffic Accident Statistical Annual Report shows that more than 90% of the accidents are collisions, and nearly 90% of the accident casualties are caused by collisions. Data from Germany show that about 30% of people do not know where they are after a car accident. At the same time, the phenomenon of driving and abandoning the car to escape occurs from time to time, which has caused great difficulties in the rescue of the wounded and the identification of accident responsibilities. However, the current automatic car accident alarm system only activates the GPS locator and the car phone to automatically call for help after the car accident occurs, and cannot send the accident information to the supervision department; Video information on people and car accidents.
