Tracking anti-theft system, tracking anti-theft method and gateway tag

Abstract

The invention relates to a tracking anti-theft system comprising a data service platform, a gateway tag which can be carried in a vehicle, and an anti-theft tag mounted on the vehicle or another object. When the power of the gateway tag is greater than a preset value or is in a charging state, a wireless radio frequency signal sent by the anti-theft tag can be received. Whether a unique identifier(UID) of the anti-theft tag is in a stolen-object database is judged. If the UID of the anti-theft tag is in the stolen-object database, a current location of a device is calculated, and data comprising current location information and the UID of the anti-theft tag is sent to the data service platform. The data service platform determines an approximate location range of a stolen object based onthe location information and a signal covering range of the gateway tag. The tracking anti-theft system has the advantage of making up for the deficiency that an existing fixed gateway has signal blank areas and can not judge whether the stolen vehicle is in the signal blank areas. The gateway tag is capable of detecting a wireless signal of the stolen vehicle and location information of an uploading device when passing through the signal blank areas of the existing fixed gateway.

Description

technical field [0001] The invention relates to the field of vehicle anti-theft, in particular to a tracking anti-theft system and method and a gateway label. Background technique [0002] The applicant once applied for a patent titled: A vehicle tracking system with the patent number 201510466475.4. The main technical solutions of the invention include servers, fixed base stations, and vehicle tags. The anti-theft principle is that the vehicle tags send radio frequency information including vehicle information. After receiving the signal, the fixed base station compares the vehicle information with the data in the stolen vehicle database, and forwards it to the server if the vehicle is a stolen vehicle. Since the geographic location of the fixed gateway is fixed and the signal range of the fixed gateway is basically unchanged, the server receives the data sent by the fixed gateway, and can determine the identity of the stolen vehicle according to the vehicle information the...

Problems solved by technology

[0003] The vehicle positioning function of this system mainly depends on the fixed gateway, which needs to be distributed in a predetermined area such as an urban area. Ideally, the signal range of the fixed gateway completely covers the entire urban area, but it is difficult to achieve in practice, and the signal coverage of the fixed gateway will exist. certain blank space

There are two main reasons. First, to achieve full signal coverage, the number of fixed gateways is required to be large, which will lead to increased equipment costs, installation costs, and maintenance costs. Therefore, in general, basic coverage is also possible. That is, it is enough to cover most of the traffic roads and residential areas; second, the complex environment and the influence of buildings on the signal reduce the theoretical signal coverage and make the circular signal range into an irregular shape resulting in blank space

[0004] When inspectors go to search for stolen vehicles, in most cases, the target stolen vehicles are in a static state. If the target stolen vehicle is in a blank area due to the influence of buildings when it is stationary, the sent The wireless signal cannot be received by the fixed gateway, which increases the difficulty of searching
