Problems solved by technology

[0002] With the rapid development of social economy, the application fields of computers are becoming more and more extensive, among which there are more and more applications in the field of data retrieval. When the traditional data retrieval method stores data, it directly stores the object position data. , and do batch data loading and statistical analysis; this method makes the data retrieval process inflexible, time-consuming and labor-intensive, resulting in poor retrieval efficiency

Abstract

The invention discloses a quick retrieval method and system based on space-time collision. The method comprises the steps: obtaining original data which comprises object track data; performing key information extraction on the original data to obtain an object identifier, positioning time and longitude and latitude; processing the longitude and latitude by adopting a Geohash algorithm to generatea grid code; processing the grid code, and generating a unique optimization code according to the processed grid code, the object identifier and the positioning time; data storage is carried out according to the sequence of the optimized codes, so that target data can be quickly obtained when retrieval is carried out based on the content of the optimized codes. Therefore, organization optimizationis performed on the position data before storage, so that the target data can be quickly acquired through the optimized information during retrieval, and the retrieval efficiency is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a fast retrieval method based on space-time collision, a computer-readable storage medium, a computer device and a fast retrieval system based on space-time collision. Background technique [0002] With the rapid development of social economy, the application fields of computers are becoming more and more extensive, among which there are more and more applications in the field of data retrieval. When the traditional data retrieval method stores data, it directly stores the object position data. , and do batch data loading and statistical analysis; this method makes the data retrieval process inflexible, time-consuming and labor-intensive, resulting in poor retrieval efficiency. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the above-mentioned technologies at least to a certain extent. Therefore, an object of t...
