Self-service tracker

Abstract

The invention relates to a self-service tracker. The tracker communicates with a control platform; the tracker includes an initial positioning module, a communication module, an inertial positioning module, an alarm module and a control module; and the tracker performs initial positioning through combining GPS positioning and cellular positioning, and performs positioning in a subsequent positioning process through adopting an inertia positioning mode. Based on organic combination of the GPS positioning, the cellular positioning and the inertia positioning, the technical problem of too stringent requirements for an environment when a single positioning technology is used can be solved; in the subsequent positioning process, the inertial positioning can achieve completely autonomous positioning without GPS or cellular data required, and therefore, improvement on the automaticity of the tracker can be benefitted. With the self-service tracker of the invention adopted, dependence on GPS signals and cellular data can be reduced, and accordingly, environmental requirements of the operation of a system can be decreased, and the robustness of the system can be enhanced.

Description

technical field [0001] The invention relates to the field of positioning, in particular to a self-service tracker. Background technique [0002] The tracker is a tracking locator, which can be used for positioning monitoring of people, vehicles, valuable goods, and pets. It has the characteristics of small size, fashionable appearance, durability and high positioning accuracy. Trackers usually rely entirely on the GPS satellite positioning system to automatically obtain GPS information and other data information, so as to achieve real-time tracking, track playback and other functions. [0003] The basic positioning principle of the GPS system is: satellites continuously send ephemeris parameters and time information. After the user receives these information, the three-dimensional position, three-dimensional direction, movement speed and time information of the GPS receiver are calculated and obtained. According to the positioning method, GPS positioning is divided into si...

Problems solved by technology

[0007] In order to overcome the shortcomings of traditional GPS technology and cellular technology, the present invention provides a self-service tracker. The tracker performs initial position positioning through GPS positioning combined with cellular positioning, and uses inertial positioning in the subsequent positioning process. Through the above three The organic combination of these two methods solves the technical problem of too strict environmental requirements when using a single positioning technology, and in the subsequent positioning process, inertial positioning can achieve complete autonomous positioning without GPS or cellular data. It is beneficial to improve the automaticity of the tracker. The present invention can reduce the dependence on GPS signals and cellular data, thereby correspondingly reducing the environmental requirements for system work and improving the robustness of the system.
