A location tracking method

Abstract

The invention discloses a location tracking method. The information terminal obtains the location information of the information terminal itself through the location system, and the information terminal actively sends the location information and safety information to the central system according to the set cycle, and one or more The monitoring device obtains the current or historical location information and security information of the information terminal through this central system, and the monitoring device will display these location information on the map graphic interface of the monitoring device; wherein, the above-mentioned positioning system receives The radio signal of the positioning satellite, and at the same time interact with the positioning server on the Internet to obtain the position information of the information terminal itself. The invention realizes the monitoring of the monitored equipment, and effectively guarantees the positioning accuracy, the real-time data and the historical record query of the information terminal.

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
