Embodiment Construction
[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0034] During the driving process of the car, dangerous driving may include: speeding driving, drunk driving, fatigue driving, etc. For the above three dangerous driving situations, different methods are usually used to detect and warn them in the prior art, and the methods are complicated and cumbersome . To solve this problem, the present invention provides an early warning method for any of the above dangerous driving, which can be intuitively and easily applied to the monitoring of any dangerous driving state.
[0035] The method for early warning of dangerous driving provided by the invention is based on the analysis of the driving state of the running car.
[0036] Specifically, see figure 1 shown.
[0037] The method includes performing ...

The invention provides a method and device used for early warning of dangerous driving. A user terminal moving with an automobile synchronously executes the following steps: acquiring position coordinates of a native machine according to a set sampling time interval threshold, and recording position coordinates of each sampling point on the native machine; sequentially identifying that whether the position coordinates acquired by the native machine are a dangerous driving position coordinate or not; and carrying out statistics on a ratio of the dangerous driving position coordinates in set sampling time, when the ratio of the dangerous driving position coordinates is more than a set safety threshold, judging the current driving state is dangerous driving state, and sending out a dangerous driving state signal. By virtue of the method, whether unordered dangerous driving state appears in traveling track of the automobile can be judged, the dangerous driving is visually and accurately analyzed and judged, and occurrence rate of a traffic accident is reduced.
Description
technical field [0001] The invention relates to the technical field of driving state monitoring, in particular to a method and device for early warning of dangerous driving. Background technique [0002] Dangerous driving is one of the important reasons leading to traffic accidents, and dangerous driving includes fatigue driving, drunk driving and so on. [0003] In order to reduce traffic accidents caused by dangerous driving, various early warning methods for dangerous driving have been developed in the prior art. For example, for drunk driving, the alcohol detection module of the mobile device is used to directly detect the alcohol concentration and convert the alcohol concentration As a signal, it is used to trigger the early warning system. This method is only used for drunk driving and requires an independent alcohol detection module, which has certain limitations. For fatigue driving or drunk driving, in the prior art, the swing amplitude and swing frequency of the ...
