Abstract

The invention discloses a vehicle dynamic weight measuring method based on neural network regression. The vehicle dynamic weight measuring method comprises the following steps: (1), data preprocessing: collecting original data of vehicle dynamic wheel weight by using a weighing sensor and preprocessing the original data; (2), data feature extraction: acquiring the characteristics of the data related to a static weight measuring scene; (3), model training: using the data characteristics as input, and training a dynamic weight measuring model by using a neural network regression algorithm; and (4), vehicle weight measuring: calculating the weight of a vehicle by the dynamic weight measuring model according to vehicle dynamic wheel weight data obtained in real time. The invention further discloses a system adopted by the vehicle dynamic weight measuring method. The vehicle dynamic weight measuring method provided by the invention has the advantages that the nonlinear relationship betweenthe dynamic wheel weight data and accurate vehicle weight can be deeply excavated, so that the accuracy of dynamic vehicle weight measuring is improved.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation applications, in particular to a neural network regression-based vehicle dynamic weighing method and a system adopted therefor. Background technique [0002] With the continuous improvement of our country's economic level, the road transportation industry has developed rapidly and has gradually become the lifeblood of the national economy. At the same time, the phenomenon of overloading and overloading of vehicles is also increasing, which not only destroys the structural facilities of the road, but also poses a great traffic safety hazard. In order to deal with this problem, my country has successively implemented truck weight charges in various places, and strengthened the management of over-limit and overloaded transportation. At present, the weighing methods of vehicles are mainly divided into static weighing and dynamic weighing. Static weighing, that is, the measurement ...
