Problems solved by technology

[0002] At present, the analysis and prediction of road conditions are based on video monitoring and statistics of traffic flow. Usually, only regular road conditions can be predicted, and only local road sections can be predicted, which has certain limitations. Now Some road condition analysis and prediction schemes are not timely enough, not smart enough, and not accurate enough

Embodiment Construction

[0042] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0043] Such as figure 1 As shown, a schematic flow chart of an OBD-based road condition prediction method provided by an embodiment of the present invention, the method includes:

[0044] S1. Obtain the ignition data and flameout data of multiple vehicles through the OBD device.

[0045] It should be noted that the ignition data includes: the time of ignition, the position information of the vehicle at the time of ignition, and the data of extinguishment includes: the time of extinguishment, the position information of the vehicle at the time of extinguishment, for example, it can be set by the ignition of the OBD device on each vehicle. , Flameout detection function, to detect the ignition and flameout of the vehi...

Abstract

The invention discloses a method and a system for predicting road conditions on the basis of OBD (on-board diagnostics), and relates to the field of internets of things. The method includes acquiringignition data and flameout data of a plurality of vehicles by the aid of OBD equipment; acquiring first road condition information of selected road sections in preset time intervals according to the ignition data and the flameout data of all the vehicles; acquiring second road condition information in a next preset time interval according to the first road condition information. The method and thesystem for predicting the road conditions on the basis of the OBD have the advantages that the road conditions of the selected road sections can be accurately analyzed on the basis of running route conditions of each vehicle, and timely and accurate prediction results can be obtained by the aid of the method and the system.

Description

technical field [0001] The present invention relates to the field of the Internet of Things, in particular to an OBD-based road condition prediction method and system. Background technique [0002] At present, the analysis and prediction of road conditions are based on video monitoring and statistics of traffic flow. Usually, only regular road conditions can be predicted, and only local road sections can be predicted, which has certain limitations. Now Some road condition analysis and prediction schemes have the disadvantages of not being timely enough, not smart enough, and not accurate enough. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an OBD (On-Board Diagnostic, on-board diagnostic system)-based road condition prediction method and system for the deficiencies of the prior art. [0004] The technical scheme that the present invention solves the problems of the technologies described above is as follows: ...
