Human-vehicle accompanying technology based on electronic fence and checkpoint information

Abstract

The invention discloses a human-vehicle accompanying technology based on an electronic fence and checkpoint information. The technology comprises the following specific implementation steps: finding out all records of a target vehicle appearing at checkpoints; grouping by all checkpoints through which the target vehicle passes; calculating geohash of the longitudes and latitudes of all the checkpoints through which the target vehicle passes; calculating geohash of the longitudes and latitudes of all electronic fence points; calculating out electronic fence points within 200 meters of the checkpoints; capturing mobile phone codes within five minutes before and after the target vehicle passes through the checkpoints, and grouping the mobile phone codes according to the passing time of the vehicle to form item sets one by one; removing the mobile phone codes of the permanent resident population near the electronic fence points according to the permanent resident population table; utilizing an FP algorithm in the pyspark to find out frequent item sets; and filtering out the item sets with relatively low occurrence frequency so as to export a result. According to the invention, the problem of information query and tracking on vehicle accompanying personnel by the public security organization currently is solved, and the public security organization can conveniently catch and captureillegal personnel in a public security case.

Description

technical field [0001] The invention relates to a geohash algorithm and an FP-growth algorithm, and uses the geohash algorithm and the FP-growth algorithm to develop a technology for accompanying people and vehicles based on electronic fence and bayonet information. Background technique [0002] Among the huge data resources in the society, the public security organs hold most of the data in the society. In order to make these data more effective and generate greater social value, it is necessary to conduct multi-dimensional mining and analysis of public security big data. At present, the public security industry is using 4G mobile phone electronic fence system (dw) public security bayonet-type equipment for wireless mobile network and electronic information technology, and there are few technical researches on finding vehicle accompanying personnel information through electronic fence and bayonet information. Contents of the invention [0003] The purpose of the present i...
