Embodiment Construction

[0052] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0053] Based on the above problems, the present invention provides a method for adjusting the data collection cycle.

[0054] refer to figure 1 , figure 1 It is a schematic flow chart of the first embodiment of the method for adjusting the data collection period of the present invention.

[0055] In this embodiment, the method for adjusting the data collection cycle includes:

[0056] Step S10, when the vehicle is detected to turn, acquire the first angular velocity corresponding to the current turning position, and calculate the second angular velocity of the vehicle rotating around the Z axis at the initial turning position according to the first angular velocity;

[0057] In this embodiment, when the data acquisition terminal associated with the vehicle detects that the vehicle generates an angular velocity, it de...

Abstract

A method and a device for adjusting a data collection cycle, the method comprising: acquiring, when it is detected that a vehicle is turning, a first angular velocity corresponding to the current turning position, and calculating, according to the first angular velocity, a second angular velocity at which the vehicle is rotating around the Z axis in the initial turning position (S10); calculating, according to a preset driving trajectory-drawing error rate, the turning radian of the vehicle driving from the initial turning position to the current turning position (S20); calculating, according to the second angular velocity and the turning radian, a data collection cycle during vehicle driving, and using the data collection cycle to adjust the GPS position information collection cycle of the vehicle (S30). The method not only reduces the network traffic of the terminal and the data processing pressure at the server terminal, but also more accurately collects the GPS position information of the vehicle during driving.

Description

technical field [0001] The invention relates to the technical field of Internet of Vehicles, in particular to a method and device for adjusting a data collection period. Background technique [0002] During normal driving, the vehicle will connect to GPS satellites for positioning, so that the server associated with the vehicle can obtain the GPS position information of the vehicle. The data collection terminal in the vehicle obtains the GPS location information collection time interval issued by the server associated with the vehicle, regularly collects the GPS location information of the vehicle during driving according to the GPS location information collection time interval, and collects the GPS location information The GPS location information is sent to the server associated with the vehicle, and the server draws the collected GPS location information as the driving track of the vehicle for user reference. When the collection time interval of the GPS location informat...
