Abstract

The embodiment of the invention discloses a driving state recognition method and device, a terminal and a storage medium, and belongs to the field of information processing. The method comprises the steps: performing feature extraction on collected driving state data, and obtaining driving state features; processing the driving state feature data through an RNN model to obtain a first output feature; performing attention calculation on the first output feature through an attention model to obtain an attention weight vector, performing scaling processing on the attention weight vector, and performing weighting processing on the first output feature according to the processed attention weight vector to obtain a second output feature; performing probability conversion on the second output feature to obtain a first probability matrix; based on the first probability matrix, determining a driving state of the mobile terminal, the driving state being used for indicating a driving state of walking of the subway or the user. According to the invention, the driving state of the subway or the walking of the user can be detected through the mobile terminal, the flexibility is high, and the identification accuracy is high.

Description

technical field [0001] The embodiments of the present application relate to the field of information processing, and in particular to a driving state recognition method, device, terminal and storage medium. Background technique [0002] At present, during the operation of public transport or subway, it is necessary to identify and monitor the driving status of these vehicles, so as to divert passengers or formulate operating strategies according to the monitored driving status. [0003] In the related technology, a speed acquisition module for acquiring the speed of the locomotive, an acceleration acquisition module for acquiring the acceleration of the locomotive, a pressure acquisition module for acquiring the brake pressure of the locomotive, and an acquisition module for acquiring the surface temperature of the brake shoe of the locomotive can be installed in the vehicle. A temperature acquisition module, and a monitoring terminal for processing the above-mentioned colle...
