Positioning tracking method

Abstract

The invention discloses a positioning tracking method. An information terminal obtains position information of the information terminal through a positioning system, the information terminal actively sends the position information and safety information to a central system according to a set period, one or more monitoring devices obtain the current position information and the current safety information or the historical position information and the historical safety information of the information terminal through the central system, and the monitoring devices can display the position information on map graphical interfaces of the monitoring devices. The positioning system receives radio signals of a positioning satellite, and carries out interaction with a positioning server on the Internet to obtain the position information of the information terminal at the same time. According to the positioning tracking method, monitoring of a monitored device is achieved, and positioning accuracy, real-time performance of data and querying of historical records of the information terminal are effectively ensured.

Description

technical field [0001] The invention relates to the technical field of mobile terminal positioning, in particular to a positioning tracking method. Background technique [0002] At present, the market has more and more demand for object-to-object (m2m, machine to machine) products, especially for object position tracking products. This kind of product can be used in car anti-theft, preventing the elderly and children from getting lost, emergency rescue and other occasions. When a scene that needs to be monitored occurs, the monitor can use a mobile portable monitoring device, such as a mobile phone, to quickly and timely monitor the monitored object and certain security controls. [0003] Patent CN97117508.X discloses a technology that uses a central system to process positioning and location tracking requests. This technology can automatically switch between several positioning methods. When one positioning method fails, it can switch to another positioning method . At t...

Problems solved by technology

[0005] 1. It is difficult to determine whether the positioning system is invalid

Because complex constraints and logical judgments are required to determine whether a certain positioning system is invalid, this method will cause poor positioning results for a certain period of time.

[0006] 2. When the positioning system is switched, it is likely to cause the drift of the positioning point

In this way, when the mobile device cannot receive the query command from the server, the requester cannot obtain any information about the mobile device

Using the "question and answer" mechanism is beneficial to reduce the amount of information interaction, but when the above situation occurs, there is no mechanism to ensure that the queryer can at least obtain the security information when the mobile device loses contact with the server for the first time, such as geographical location

[0010] 2. This method cannot guarantee that the requester obtains the security history information of the mobile device before the request is sent

If the map information is to be displayed graphically on the monitoring terminal, because the data volume of general map information is huge, this will generate a large amount of communication data and consume communication costs. Monitor objects for real-time monitoring

If the monitoring terminal only uses text to describe the geographical location of the monitored object, the ease of use will be greatly reduced, resulting in a poor user experience
