Abstract: The present disclosure relates to a charging guidance method for fast charging loads based on an adjustable and graded charging service fee, including: establishing a fast charging load prediction model based on a trip chain and a Monte Carlo method to predict a fast charging demand and a spatial-temporal trajectory change of a user trip; deciding a charging location based on a weighted user charging location decision model, and calculating a fast charging load of each charging station; constructing a regional graded charging service fee adjustment model with a minimum sum of absolute values of voltage deviations of nodes in the distribution network in a region as an optimization objective, and optimizing and adjusting the charging service fee; and determining an optimal user charging location under fast charging loads by using the weighted user charging location decision model based on the adjusted charging service fee.

Abstract: Disclosed is a vehicle fuel economy evaluation method based on data analysis. The method combines data processing and a fuel model with an enhanced learning mechanism to predict fuel consumption, analyze driving behavior and output an improvement suggestion. With continuous enhanced learning and long-term dynamic improvement, the model will be able to predict economic fuel consumption in an increasingly accurate way, along with specific and intuitive driving behavior suggestions to help drivers to drive economically.

Abstract: A method for detecting the load mass of a commercial vehicle includes the following steps. Step S1, data preprocessing: including data analysis, cleaning, noise processing and other operations for original terminal data of the vehicle. Step S2, identification and analysis of working conditions: further analyzing the working conditions according to the preprocessed data. Step S3, data screening: determining whether data with the working conditions analyzed belong to test data or training data; proceeding to step S5 if the data belong to test data, or proceeding to step S4 if the data belong to training data. Step S4, model construction and combination: constructing a plurality of different basic models through the training data in the step S2, and finally combining the models through training and screening.

Abstract: An image transmission method and an apparatus are provided. The image transmission method is applied to a system in which a client device establishes a remote desktop connection to a server and includes dividing an image according to at least two pixel scales, to obtain multiple image blocks in each pixel scale, determining a hash value of each image block in each pixel scale, querying a cache according to the hash value of each image block in each pixel scale, setting a sending flag bit of each image block in each pixel scale according to a query result, and sending, according to the sending flag bit of each image block in each pixel scale, information about the image block to the client device using the remote desktop connection in order to reduce redundant data with lower computation complexity and space complexity and reduce a requirement for bandwidth.
