Vehicle trajectory query system and method

Abstract

The invention provides a vehicle trajectory query system and method. The method comprises following steps: a voice input module converts the voice of a user into a digital audio signal; a keyword extraction module performs keyword matching and extracting operation for the digital audio signal according to a current voice library; a grammatical analysis module sends keywords to a position query module when the grammatical analysis module receives keywords meeting preset requirements; the position query module takes corresponding position data from a memory module according to the keywords; a trajectory analysis module analyzes and processes the position data of the received position data and then obtains corresponding text information; the text information is synthesized into a first prompt tone by a voice synthesis module; the voice synthesis module sends the prompt tone to a voice output module through a second communication module and a first communication module; and the voice output module broadcasts the first prompt tone. By employing the query system and method, the user can feel less tired in eyes and hands when the user queries the vehicle trajectory, and the query efficiency, query accuracy and universality are further improved.

Description

technical field [0001] The invention relates to the field of vehicle supervision, and more specifically, relates to a vehicle trajectory query system and a query method. Background technique [0002] In the field of vehicle supervision, the vehicle positioning system has been widely used, especially for the query of the historical position of the vehicle (multiple positions can also form a track). With the rapid improvement of network speed, the query frequency is getting higher and higher, and the amount of information is getting bigger and bigger. Therefore, the workload of supervising violations of rules and regulations in vehicle operation has increased dramatically. For example, when replaying the track of a vehicle, if the track is played back point by point, the playback speed is slow, the time is long, and the query efficiency is low, and if the complete track is drawn on the map at one time without track playback, then It makes it difficult for users (mainly monit...
