Embodiment 1

[0045] In view of the fact that the suspected vehicle involved in the case frequently changes the license plate, changes the license plate number, blocks the license plate, etc., so that the vehicle number captured by it is non-continuous, this embodiment provides a method for searching for suspects based on big data. The method for the vehicle will be described below in conjunction with the accompanying drawings.

[0046] figure 1 It is a flow chart of the method for finding suspected vehicles based on big data in the invention. See figure 1 , the method uses the Hadoop platform to search for suspected vehicles, including:

[0047] Step S101: condition screening step

[0048] Designate screening conditions according to the suspect vehicle, and determine the target checkpoint and the time range for the suspect vehicle to pass through the target checkpoint, wherein the screening conditions include: the vehicle model, color and suspect license plate number of the suspect vehi...

Embodiment 2

[0066] In order to solve the above technical problems, the present invention also provides a system for finding suspected vehicles based on big data, image 3 For a schematic structural diagram of a system for finding suspect vehicles based on big data in the present invention, please refer to image 3 , the system uses the Hadoop platform to search for suspected vehicles, including: a condition screening module 1, a driving route calculation module, a suspect vehicle screening module 3 and a data cleaning module 4.

[0067] The condition screening module 1 is configured to specify a screening condition according to the suspect vehicle, and determine a target checkpoint and a time range for the suspect vehicle to pass through the target checkpoint, wherein the screening condition includes: the vehicle type of the suspect vehicle , color and suspect license plate number, the target bayonet includes at least one main bayonet, n upstream bayonets and m downstream bayonets, where ...

Abstract

During a crime process of a suspected vehicle, through modes of frequently replacing a license plate, changing the license plate, shielding the license plate and the like, the shot vehicle license plate is non-continuous. Aiming at the above situation, the invention provides a method and a system for searching the suspected vehicle based on big data. The method is characterized by through using aHadoop platform, dynamically analyzing an order relation of a vehicle passing bayonet and normal distribution of vehicle passing time, which is not influenced by factors of weather at the time of an accident, a road condition and the like; based on the dynamic order relation and the normal distribution of the vehicle passing time, providing relative accurate data for comparison analysis of upstream and downstream vehicle passing; and according to a preliminarily-determined vehicle model, searching the suspected vehicle and reducing a search range of the suspected vehicle. A support is providedfor criminal detection, police strength is greatly saved, time for determining the suspected vehicle is shortened and criminal detection efficiency is increased.

Description

technical field [0001] The invention belongs to the technical field of data search, and in particular relates to a method and system for searching suspect vehicles based on big data. Background technique [0002] With the development of society and the advancement of technology, cars have gradually entered thousands of households. Owning a car is no longer a dream for some people, nor is it a status symbol. However, while the advancement of technology has brought convenience and speed to ordinary people, it has also become a sharp weapon for some criminals to commit crimes. At present, there are endless incidents of using cars as criminal tools: such as hit-and-run, driving to flee, driving to follow and so on. Moreover, in some car-related cases, the suspect will frequently change the license plate number, cover the license plate number or modify the license plate number to avoid tracking. These actions of them have brought great difficulty to the detection of the case and...
