Embodiment 1

[0049] In the first embodiment, the request information may also include a user ID and a temporary password; the temporary password is the authentication information sent by the server to the client when the client logs in to the server and establishes a connection successfully, and the user ID and temporary password can be used for Subsequent user and client authentication is used to verify whether the user who submits the vehicle track query request has the query authority and to verify the legitimacy of the client. The user ID can indicate the identity of the vehicle owner.

[0050] In the first embodiment, the daily trajectory data of each vehicle is stored in the database in the form of an array structure; such as figure 2 As shown, the array includes vehicle identification code information, the number of trajectories of the vehicle on the day, the start time and the number of position points corresponding to each trajectory, and the data of each position point.

Embodiment 2

[0070] In the second embodiment, the request information may also include a user ID and a temporary password; the temporary password is the authentication information sent by the server to the client when the client logs in to the server and establishes a connection successfully, and the user ID and temporary password can be used for Subsequent user and client authentication is used to verify whether the user who submits the vehicle track query request has the query authority and to verify the legitimacy of the client. The user ID can indicate the identity of the vehicle owner.

[0071] In the second embodiment, the daily trajectory data of each vehicle is stored in the database in the form of an array structure; such as figure 2 As shown, the array includes vehicle identification code information, the number of trajectories of the vehicle on the day, the start time and the number of position points corresponding to each trajectory, and the data of each position point.

Abstract

The invention relates to a method for sampling vehicle trajectory data, a client and a server. The method comprises the following steps: generating vehicle trajectory query request information according to user input information; wherein the request information comprises query time span information and vehicle identification code information; sending the vehicle trajectory query request information to a server; receiving a trajectory query result returned by the server; wherein the trajectory query result is sampling data obtained by the server by querying trajectory data, corresponding to thequery time span, of a target vehicle matching the vehicle identification code information in a database according to the request information and sampling the trajectory data according to a preset sampling interval. The problem of querying vehicle trajectories in a longer period can be solved, the query efficiency is improved, and the sexual function pressure of the client and the server is reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle data processing, in particular to a method, a client and a server for sampling vehicle trajectory data. Background technique [0002] The storage of the existing vehicle driving track data is to send all the vehicle position data to the vehicle client. The background pre-calculates the total number of fixed vehicle position data and writes it into the cache. When the vehicle client requests the query data, the cached data is returned. Among them, the vehicle position data is sampled at the vehicle end with a cycle of 1 second, so that each vehicle will generate a large amount of position data every day, and the rendering of a large amount of data will appear when the driving trajectory of a long time interval is depicted. Both the client and the server are under heavy pressure. Therefore, the existing vehicle driving trajectory data only stores the trajectory query of the latest week, and cannot ...
