Internet-of-vehicle data transmission method and system

Abstract

The invention belongs to the technical field of an internet of vehicles and discloses an internet-of-vehicle data transmission method and system. The internet-of-vehicle data transmission system comprises an image acquisition module, a vehicle speed acquisition module, an oil volume acquisition module, a power acquisition module, a main control module, a data filtering module, a network communication module, a positioning module and a display module. The travel data is filtered and modified through the data filtering module, thereby further improving the accuracy and stability of an algorithmand greatly improving the accuracy of the vehicle data; and meanwhile, through the positioning module, the track of a vehicle to be positioned is matched with the road, then, position deviation obtained through matching is utilized to correct location of nearby vehicles, path matching of the corrected nearby vehicle tracks is carried out again, and the obtained position deviation is utilized to correct the track of the vehicle to be positioned, thereby improving precision of the track of the vehicle to be positioned and improving positioning precision of the vehicle to be positioned on an electronic map. The method can be used for vehicle positioning of the electronic map.

AI Technical Summary

Problems solved by technology

[0004] (1) The data collected by the existing Internet of Vehicles is easy to generate a large amount of redundant data, and the accuracy of the collected data is poor; at the same time, the accuracy of matching the trajectory of the vehicle with the geometric shape of the road is not high, which leads to the accuracy of the position of the vehicle on the electronic map not high problem

[0005] (2) The images collected by the existing Internet of Vehicles data transmission system have low resolution and cannot obtain image data that is convenient for human perception and system analysis and processing

[0006] (3) During the process of collecting vehicle speed in the existing Internet of Vehicles data transmission system, the sensor is easily affected by the environment, which reduces the detection accuracy of the speed sensor and increases the storage capacity and calculation capacity of the control system

[0007] (4) In the process of collecting vehicle power data by the existing Internet of Vehicles data transmission system, the power detector is prone to non-linear errors due to faults
