detailed description

The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

A global positioning networking communication tracking method provided in this embodiment comprises the following steps:

S1. Each locator sends its own GPS data information to each tracker within its signal coverage range irregularly or periodically through radio signals;

S2. After receiving the corresponding signal, the tracker b within the signal coverage of the locator in step S1 will decode the signal and pair it with the locator corresponding to the signal;

In step S2, if case A occurs: the pairing is successful, display the GPS data information of the locator and upload the GPS data information of the locator to the cloud server through the Internet; if case B occurs: the pairing is unsuccessful, then Upload the GPS data information of the locator to the cloud server through the Internet;

S3. The cloud server stores the GPS data information uploaded by each tracker to form a database;

S4. The tracker outside the signal coverage of the locator in step S1 sends a request instruction to the cloud server through the Internet, and the cloud server searches the database for GPS data information paired with the tracker according to the received request instruction ;

In step S4, if case C occurs: the GPS data information paired with the tracker is found and the pairing is successful, the tracker downloads the GPS data information through the Internet and displays it.

Since a locator is paired with at least one tracker or a tracker is paired with at least one locator in advance to form one-to-one, one-to-many, many-to-many and other pairing forms, in order to fully explain the above steps, As shown in Figure 1 and Figure 2, a total of five trackers (numbered 1-5), ten locators (numbered 001-010) and one cloud server are set up; among them, tracker 1 has been paired in advance or originally with positioning Tracker 001, Tracker 2 was previously or originally paired with Locator 002, Tracker 3 was previously or originally paired with Locator 002, Tracker 4 was previously or originally paired with Locators 003, 004, 005, and 006, and Tracker 5 was previously or originally paired with Locator 002 The original pair has locators 005, 006, 007, 008, 009 and 010.

When many targets (such as the elderly, children, pets, luggage, equipment, etc.) move to different positions with their respective locators (ie 001-010), the following distribution will occur:

The locator 001 is within the wireless signal receiving range of the tracker 1;

The locator 002 is within the wireless signal receiving range of the tracker 2;

The locator 003 is within the wireless signal receiving range of the tracker 2 and the tracker 3 at the same time;

The locator 004 is within the wireless signal receiving range of the tracker 4;

The locator 005 is within the wireless signal receiving range of the tracker 4;

The locator 006 is within the wireless signal receiving range of the tracker 5;

The locator 007 is within the wireless signal receiving range of the tracker 5;

The locator 008 is within the wireless signal receiving range of the tracker 5;

The locator 009 is within the wireless signal receiving range of the tracker 1;

Locator 010 is within the wireless signal receiving range of tracker 1, tracker 2 and tracker 3 at the same time;

Therefore, when each locator (001-010) sends a signal to the outside, the corresponding tracker (1-5) will realize the following operations:

Tracker 1 is successfully paired with tracker 001 and displays the GPS data information of tracker 001. At the same time, the GPS data information of tracker 009 and tracker 010 is uploaded to the cloud server. The data information is uploaded at the same time to update the database in the cloud server;

The tracker 2 successfully paired with the tracker 002 and displayed the GPS data information of the tracker 002, and uploaded the GPS data information of the tracker 003 and the tracker 010 to the cloud server. The information is uploaded at the same time to update the database in the cloud server;

The tracker 3 will upload the GPS data information of the locator 003 and the locator 010 to the cloud server to update the database in the cloud server; since the locator 002 is not within the range of its signal reception, the tracker 3 can download from the cloud server through the Internet Find the latest GPS data information of the locator 002 in the database and download it, so as to realize the tracking of the locator 002;

The tracker 4 successfully paired the tracker 004 and the tracker 005, and displayed the GPS data information of the tracker 004 and the tracker 005. At the same time, the user can decide whether to upload the GPS data information of the tracker 004 and the tracker 005 to the cloud server; Because the locator 003 and the locator 006 are not within its wireless signal receiving range, the tracker 4 can search and download the latest GPS data information of the locator 003 and the locator 006 from the database of the cloud server through the Internet, thereby realizing the tracking of the locator. Tracking of 003 and Locator 006;

Tracker 5 has successfully paired Tracker 006, Tracker 007 and Tracker 008, and displays the GPS data information of Tracker 006, Tracker 007 and Tracker 008. The GPS data information of the locator 008 is uploaded to the cloud server; since the locator 009 and the locator 010 are not within the range of its wireless signal reception, the tracker 5 can find the latest updates of the locator 009 and the locator 010 from the database of the cloud server through the Internet GPS data information and download, so as to realize the tracking of locator 009 and locator 010;

In this way, using the above method, many trackers and locators can be integrated into a global network search system through the cloud server. When a target carries its locator beyond the wireless receiving range of its paired tracker, the locator It will automatically send its own information to other nearby trackers, and use other trackers to upload the information to the cloud server. At this time, the tracker paired with it can obtain the information of the locator through the cloud server, thereby avoiding The positioning is lost and a comprehensive tracking effect is achieved.

In order to ensure that the tracker of the lost target can find its paired locator and ensure the reliability of the tracking, in step S4, if case D occurs: no GPS data information paired with the tracker is found, the cloud server adopts The following two ways:

When the user sends a request command to the cloud server through the Internet according to the demand, the cloud server cannot find the GPS data information of the tracker 002, and can only wait until the tracker 002 appears on the tracker When any one of the wireless signals in (1-5) is within the receiving range, the cloud server updates the GPS data information of the locator 002 in the database, and then, the cloud server actively sends the GPS of the locator 002 to the tracker 3 according to the recorded request instruction The data information is actively downloaded by the tracker 3 when waiting for the next request instruction from the tracker 3 or passively.

In order to optimize the content of GPS data information, ensure the accuracy of tracking and reduce data redundancy, the GPS data information sent by each tracker includes the identification number of the tracker (that is, the number that matches the identification number of the tracker) and GPS Geolocation coordinates, whereby a map display can be made on the interface of the tracker's software application.

In order to ensure the coverage of the wireless signal and ensure a comprehensive scan of the signal to prevent omissions, in step S1, the locator uses a UHF radio wave signal (i.e. UHF) to each tracker within its signal coverage Send its own GPS data information, and at the same time, each tracker performs uninterrupted scanning in the frequency band of UHF radio waves, so that the signal can be guaranteed to cover an area with a radius of 3 kilometers.

Further, in order to reduce the data storage cost of the cloud server and ensure the timeliness of the database, in step S3, after the cloud server decodes the GPS data information uploaded by each tracker, the received information is duplicated with that in the database. The information is filtered out to update the database in real time to ensure that the GPS data information downloaded by the relevant tracker is the latest data; of course, the information within the relevant period can also be retained to facilitate the search for the tracker's path.

In this way, the radio receiver e under the control of the first microprocessor 3 will perform uninterrupted frequency scanning in the preset frequency band. When a signal sent by the locator b is received on a certain channel, the first The microprocessor 3 quickly decodes the signal and restores the data, and at the same time the first memory 4 stores the data, and then transmits it to the display terminal 5 for display in a wired or wireless manner; while the first energy storage battery 1 can be stably The pressing chip 2 provides a stable voltage for the entire tracker c.
