The invention discloses a high-performance fence judgment method based on a dynamic index for travel business, comprising the following steps: obtaining a fence judgment request, the fence judgment request including a location point and the current time; loading the corresponding Current period index; load the geofence collection; according to the geofence sorting of the current period index, determine whether the location point is within one of the geofence collections; if so, return the hit result, and update the current period of the geofence based on the hit result index; otherwise, returns a miss result. The present invention introduces a period-by-period index, aiming at the fact that the number of hits of the map fences in different periods is different, making the index closer to the actual situation, ensuring that hotspot geographical fences with high hit probability times are ranked at the top, thereby increasing the probability of a hit and reducing Judgment times.
Description
technical field [0001] The invention belongs to the technical field of computer data processing, and in particular relates to a dynamic index-based high-performance fence judgment method, device and electronic equipment for travel business. Background technique [0002] Geo-fencing is a new application of LBS, which uses a virtual fence to enclose a virtual geographic boundary. Use geofences (that is, a set of closed longitude and latitude coordinate pairs) to divide cities or regions. When operating online car-hailing, different operating strategies can be adopted based on the geofences of specific cities or regions. Therefore, how to be efficient It is a technical problem to be solved urgently to judge whether a certain point is in the fence. [0003] And the applicant found that the following technical problems exist in the prior art: [0004] Geofencing generally connects many points on the map to form a polygonal area. The existing technology uses R-tree index and ray...
