The invention discloses a dynamic index-based high-performance fence judgment method for travel business, which comprises the following steps of: acquiring a fence judgment request which comprises a position point and current time; loading a corresponding current time period index based on the current time of the judgment request; loading a geo-fencing set; judging whether the position point is in one of the geo-fences of the geo-fence set according to the geo-fence sequence of the current time period index; if yes, returning a hit result, and updating the current time period index of the geo-fence based on the hit result; and if not, returning a miss result. According to the method, by introducing the time-phased index, the index is closer to the actual condition aiming at the condition that the hit times of each map fence in different time periods are different, and the hotspot geofence with high hit probability times is ensured to be arranged at the foremost, so that the probability of one-time hit is increased, and the judgment times are reduced.
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...
