Embodiment Construction
[0040] In order to make the objects, technical solutions, and advantages of the present invention, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are merely the embodiments of the invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained without making creative labor without making creative labor, in the premise of creative labor.
[0041] Next, a specific massive trajectory query method provided in the present application embodiment will be described in conjunction with the accompanying drawings.
[0042] Such as figure 1 As shown, the massive trajectory inquiry provided in the present application embodiment includes:
[0043] S101, receive query requests for query objects and acquire multiple trajectory data of the query object; the trajectory data includes time information and / or spatial location information;
[0044] S102, the trajectory da...

The invention relates to a massive track query method and system, and a retrieval server. The method comprises the following steps: receiving a query request of a query object, and obtaining multiple pieces of track data of the query object; and encapsulating the track data of the query object into a tree structure with a plurality of leaf nodes, wherein a father node of the tree structure comprises identification information and last position information of a query object, a leaf node comprises information of a single track or multiple tracks of the query object in a period of time or multiple different space ranges, and a child node under the leaf node comprises track information of a same row and an accompanying object of the track. Based on the query condition of free combination of time and space, the purposes of quickly retrieving, reducing and efficiently drawing the mass track data are achieved, the pressure of receiving and displaying the mass data by a client is greatly reduced, and the massive track data are more quickly, clearly and intuitively displayed.
Description
Technical field [0001] The present invention belongs to the technical field of communication, and more particularly to a massive trajectory query method, retrieval server and system. Background technique [0002] The current massive trajectory data query and display system, the main research direction is in two aspects, one is a selection of invention and improvement techniques for storage, query algorithms, which can combine a certain business scene in two aspects. More accurately query and draw the trajectory of business objects in massive data; the other is based on the condition of the query, retrieves all the qualified data sets in the business object massive trajectory data, and the set is returned to the query end, and then The query side is drawn in the map data collection, which can meet the query and display of the retrieval object massive trajectory data single or multiple trajectories. But it has the following shortcomings: [0003] Massive trajectory query method, th...
