Problems solved by technology
At this stage, when a vehicle has a traffic accident, it often requires manual operation by the traffic participant to call the police, which is less time-sensitive, especially when a serious traffic accident occurs, or in a sparsely populated place, or when there is an illegal behavior such as escaping after the accident. There is a problem that it is difficult to locate the accident in a timely and accurate manner, which is not conducive to rescuing the injured and restoring the process of the traffic accident, thus causing greater losses

The invention provides a traffic accident detection and alarm method based on an intelligent vehicle-mounted terminal. The intelligent vehicle-mounted terminal identifies the traffic accident and uploads the time, the place and the type of the accident, so that the traffic rescue is quicker and more effective. The intelligent vehicle-mounted terminal can utilize a built-in high-precision accelerometer and a gyroscope to calculate and correct to obtain the current posture and driving state of the vehicle, so as to judge whether the vehicle has a traffic accident or not and the grade of the accident, record the time and position of the traffic accident, and give an alarm and report to the platform after time delay. Thus, positive effects are achieved for timely handling traffic accidents and rescuing the wounded. In addition, the function of manually cancelling the alarm is added in the alarm delay, so that the possibility of false alarm of the intelligent vehicle-mounted terminal can be effectively avoided, and the reliability of traffic accident reporting is improved.
Description
technical field [0001] The invention relates to the technical field of early warning of vehicle traffic accidents, and in particular relates to a method for detecting and alarming traffic accidents through a vehicle-mounted terminal of an intelligent vehicle. Background technique [0002] With the development of social economy, the number of vehicles is increasing, and the road conditions are becoming more and more complex. The possibility of vehicle accidents increases significantly. How to discover, locate and deal with traffic accidents in time has a positive effect on saving lives and quickly restoring road traffic. Especially when a traffic accident occurs in a sparsely populated place, or there is an illegal escape from the accident, it is more important to timely and accurately identify the traffic accident and call the police in time to save the injured and restore the process of the traffic accident. At this stage, when a vehicle has a traffic accident, it often re...
