A location tracking method based on two-dimensional barcode

Abstract

The invention provides a position tracing method based on a two-dimensional bar code. With the adoption of the position tracing method, accurate locations of position personnel can be determined by depending on a GPS (Global Position System) and a monitoring point, and image information of the position personnel can be shot, so that whether the position personnel have relevant qualification at the monitoring point can be determined accurately, and a management bug is eliminated. Relevant information can be sent to an upper server by a GPRS (General Packet Radio Service) through a handheld terminal without additional transmission equipment, so that the cost is saved, and the method is convenient to operate.

Description

technical field [0001] The invention relates to a positioning method, in particular to a positioning tracking method based on a two-dimensional barcode. Background technique [0002] In the existing technology, the well-known technology is that at present, the personnel who need to locate and manage all need qualifications and rich missions. At present, they all use "dispatch-check-return-manual input report" and "station-check-manual networking Entry report" process management. This solution mode is undoubtedly effective but by no means the optimal solution. It always has the problem of whether the parties strictly follow the process (whether they are themselves and whether they have reached the specified position), so there are serious management loopholes. [0003] Existing positioning technologies are roughly classified into continuous positioning. [0004] Continuous positioning technology is based on GPS (Global Positioning System) or wireless communication base stat...

Problems solved by technology

[0005] GPS positioning technology covers a wide range and can provide positioning information at any location. However, there are problems such as limited positioning accuracy and the inability of the signal to radiate indoors. It cannot provide accurate location information, so it is only suitable for positioning accuracy such as long-distance driving positioning. insensitive applications

[0006] Wireless communication base station positioning technology can provide high-precision positioning information in theory, but limited by the coverage of base station signals, it cannot provide positioning information at any location, and the shielding effect, reflection effect and multipath interference of indoor signals will affect The accuracy of positioning information cannot provide stable positioning information for indoors, which is the main place for personnel activities

[0007] To sum up, the continuous positioning technology is not suitable for the positioning of personnel, which is the deficiency of the existing technology
