Method and device for identifying vehicle aggregation event based on GPS signal data

Abstract

The invention discloses a method and device for identifying a vehicle aggregation event based on GPS signal data, and the method and device are applied to vehicles to be detected, and comprise the steps: obtaining the GPS signal data of each vehicle to be detected under the condition that an aggregation identification request for each vehicle to be detected is received; identifying a target vehicle and a target gathering place of the target vehicle in each to-be-detected vehicle through at least one of a same-position interruption gathering algorithm, a same-position stay gathering algorithm and a same-position repeated occurrence gathering algorithm based on the GPS signal data; acquiring offline verification data corresponding to the target vehicle and the target gathering place; and based on the offline verification data, the target vehicle and the target gathering place, determining whether the target vehicle has a vehicle gathering event. In the process of determining the vehicle gathering event, multiple methods are adopted to determine the target vehicle and the target gathering place, and whether the target vehicle is the vehicle gathering event or not is jointly determined based on the offline verification data, so that the accuracy of vehicle gathering event identification is improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and device for identifying vehicle aggregation events based on GPS signal data. Background technique [0002] At present, auto financial service manufacturers use GPS data to identify whether vehicles have aggregation or concentration risks, mainly by delineating some potential high-risk locations on the map in advance, such as second-hand car trading markets, areas where car repairs are concentrated, and borrowing. Areas where intermediaries gather, locations of public security organs, etc. Secondly, it is judged by the algorithm that once the vehicles entering the area and staying in the area for a long time exceed a certain threshold, it will be considered as a vehicle gathering. [0003] However, once the place where the vehicles gather is not within the pre-delineated range, it cannot be identified. In addition, many potential high-risk areas are extremely...

Problems solved by technology

[0005] In view of this, the present invention provides a method and device for identifying vehicle aggregation events based on GPS signal data, which is used to solve the current vehicle aggregation algorithm mainly judged by the duration and number of vehicles in the preset electronic fence. A vehicle gathering event occurred in the fence, and the coverage is limited. The identification of the vehicle gathering event is not accurate, and it is easy to cause the omission of risk warning. The specific plan is as follows:
