Problems solved by technology

[0004] In some current similar applications, in order to solve this problem, most of them use methods such as limiting the total amount of data obtained each time, filtering and obtaining part of the data at a fixed time interval, and obtaining only a single location data. Although this can solve the performance problem of the front-end display, But at the same time, there will be problems that cannot meet the actual needs of users.

Embodiment Construction

[0018] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further explained below in conjunction with specific embodiments.

[0019] A vehicle trajectory data aggregation operation method, the steps include:

[0020] (1) According to the time period and vehicle information conditions input by the user, obtain the original position and status information data collection of the vehicle from the data source. The data source is the established vehicle historical trajectory database. The establishment process of the vehicle historical database is as follows: The vehicle is running In, the operation status information is uploaded to the general control center through GPS, and the general control center sorts and stores the information according to peak, flat peak, and night time by day, and updates the historical database at the same time;

[0021] (2) Preprocess the original data, extra...

Abstract

The present invention discloses a vehicle trajectory data aggregation operation method. The method is based on a lot of vehicle GPS position data and vehicle state data and is combined with a complicated but optimized application program operation process to obtain the aggregation operation method which enables a front end map page to display the vehicle trajectory and state information data content rapidly and accurately, and solves the performance problem in the prior art of displaying the mass position and state data on the front end map page.

Description

Technical field [0001] The invention relates to the field of vehicle transportation and management, and in particular to a vehicle trajectory data aggregation operation method. Background technique [0002] With the rapid development of Internet technology, there are more and more services and products based on geographic location. All kinds of government and enterprise units, especially the logistics industry with a large amount of vehicle resources, have used them to improve their management level and work efficiency. The location data information system needs to manage vehicle resources, and the application of vehicle trajectory data is an essential part of it. [0003] The trajectory data of the vehicle refers to the GPS geographic location data collected and uploaded by the vehicle-mounted intelligent terminal during the actual operation of the vehicle, and it also contains the instantaneous state information data of the vehicle. Generally, the frequency of GPS data collected...
