Embodiment Construction

[0050] 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.

[0051] Such as figure 1 Shown is a schematic flow chart of an online monitoring method for road icing and snow melting provided by an embodiment of the present invention. The online monitoring method for road icing includes:

[0052] Acquire the sample data of icing and snow melting and ice melting, mark the sample data according to the state information of icing and snow melting and ice melting, and obtain the sample label data. The state data of icing and snow melting and ice melting, as well as the state data of icing and snow melting and ice melting collected from laboratory icing and snow melting and ice melting experiments;

[0053] Constructing a deep neural network, and training the sample label data throug...

Abstract

The invention discloses a road icing, snow melting and deicing online monitoring method and system. The method includes the following steps that: the sample data of icing, snow melting and deicing areacquired, and the sample data are marked according to the state information of the icing, snow melting and deicing, so that sample marked data are obtained; a deep neural network is constructed, andthe sample marked data are trained through the deep neural network, so that the estimated value of at least one key parameter is obtained; the meteorological information of a monitored area is obtained, and statistic analysis is performed on the meteorological information through a statistical judging algorithm, so that the target parameter value of the monitoring area is obtained; and whether road icing or snow melting and deicing occurs in the monitoring area is judged through the statistical judging algorithm according to the estimated value of the key parameter and the target parameter value of the monitored area.

Description

technical field [0001] The invention relates to the field of road safety, in particular to an online monitoring method and system for road icing and snow melting and ice melting. Background technique [0002] In winter, roads in high-altitude areas and in northern parts of the country freeze and melt snow and ice, which reduces the friction between the tires of passing vehicles and the ground, resulting in vehicle skids and sideslips, which have a great impact on driving safety. Providing timely and effective road safety information for vehicles in various road scenarios (especially roads prone to traffic accidents) is not only an area that road traffic management departments / operating companies focus on and actively deploys technological means to guarantee, but also a field that current car manufacturers Actively investing in the field of research and development is an important supporting technology necessary for intelligent driving and driverless driving. [0003] For th...
