Fig. 1 shows a schematic flow diagram of a wireless network based tracking method according to an embodiment of the invention. As shown in fig. 1, an embodiment of the present invention provides a tracking method based on a wireless network, including the following steps:

step 101, monitoring whether a tracking system fixed on a tracking target is separated from the tracking target;

102, when the tracking system is monitored to be separated from a tracking target, generating a trigger signal; and

step 103, in response to the trigger signal, sending alarm information of the tracking system to the associated device of the tracking system.

The following describes the steps in the wireless network-based tracking method in further detail:

in step 101, it is monitored whether the tracking system fixed on the tracking target is separated from the tracking target.

The tracking system is fixed on a tracking target to be tracked through a fixing device. The tracking target may be a person who is easily lost, such as a child or an old person, or a domestic animal, a poultry, or an economic animal, and the present invention is not limited thereto. The tracking system may be fixed to the tracking target in various ways, such as a watch, a bracelet, a foot ring, a collar, or an ear tag, but the invention is not limited thereto. The system may monitor whether the tracking system is out of the way of the tracking target via sensors. The fixtures of the tracking system may be dislodged or damaged from the tracking target by a malicious person in an unexpected situation. Therefore, when the tracking system is separated from the tracking target, the tracking target may be stolen, abducted, kidnapped or lost.

Optionally, monitoring whether the tracking system fixed on the tracking target is separated from the tracking target may include: monitoring whether a fixture of the tracking system is unfastened or broken; and determining that the tracking system is separated from the tracking target when the fixing device is monitored to be unlocked or damaged.

The system can determine whether the tracking system is disengaged from the tracking target by monitoring whether the fixture is unfastened or broken. When the fixation device is detected to be unfastened or broken, the system can determine that the tracking system is detached from the tracking target. Taking the lost tracking watch used by the child as an example, the lost tracking watch for the child should be fixed on the child body by wearing on the wrist of the child. When the wrist band of the tracking watch is unfastened or cut, the tracking system can determine that the tracking watch is separated from the body of the child.

Optionally, monitoring whether the tracking system fixed on the tracking target is separated from the tracking target may include: monitoring whether the distance between the tracking system and the tracking target is greater than a preset threshold value or not; and when the monitored distance is greater than a preset threshold value, determining that the tracking system is separated from the tracking target.

The system can judge whether the tracking system is separated from the tracking target by monitoring whether the distance between the tracking system and the tracking target is larger than a preset threshold value. The distance monitoring may be performed by a distance sensor, which may be disposed on a surface of the fixing device contacting the body of the tracking target, and measures a distance between the fixing device and the tracking target. Thus, when the monitored distance is greater than the preset threshold, the system may determine that the tracking system is out of tracking proximity. The value range of the preset threshold can be reasonably set according to practical experience, and the invention is not limited to this. Still taking the child missing tracking watch as an example, a distance sensor may be disposed on the inner side (i.e., the side close to the human body) of the tracking watch, for example, the distance sensor is disposed on the back of the watch face of the tracking watch. The distance sensor continuously monitors the distance between the watch and the body of the child. When the distance monitored by the distance sensor is greater than a preset threshold value, the tracking system can determine that the tracking watch is separated from the body of the child.

Alternatively, the monitoring whether the tracking system fixed on the tracking target is separated from the tracking target may be monitoring whether the tracking system fixed on the tracking target is abnormally separated from the tracking target.

The system can also monitor whether the tracking system is abnormally separated from the tracking target, and does not monitor the condition that the tracking system is normally separated from the tracking target. By monitoring the condition that the tracking system is abnormally separated from the tracking target, the system can accurately judge whether the tracking target has accidental conditions such as missing and the like.

Optionally, the monitoring whether the tracking system fixed on the tracking target is abnormally separated from the tracking target may include: monitoring whether a fixing device of the tracking system is damaged or not unfastened in a preset mode; and when the fixing device is detected to be damaged or not unlocked in a preset mode, determining that the tracking system is abnormally separated from the tracking target.

By monitoring whether the fixing device of the tracking system is damaged or not unfastened in a preset mode, the system can judge whether the tracking system is abnormally separated from the tracking target or not. When the fixing device is detected to be damaged or not to be unlocked in a preset mode, the system can determine that the tracking system is abnormally separated from the tracking target. Still taking the tracking watch for the lost child as an example, a metal wire forming a circular conduction loop may be disposed in the fixing device of the tracking watch (i.e. the wrist strap of the watch). When a malicious person destroys the wrist strap of the watch (for example, cuts off the wrist strap of the watch), the metal wire is correspondingly destroyed, the conducting loop is also broken, and the system can determine that the tracking watch is abnormally separated from the child. In addition, whether the watch is abnormally separated from the tracking target can be judged by presetting a normal unlocking mode for the child lost tracking watch. For example, the normal unlocking mode may be set to require password authentication before unlocking the watch. In this way, the system may determine that the tracking watch is abnormally disengaged from the child when the tracking watch is not unlocked in a predetermined manner. The preset unlocking manner may also be fingerprint authentication, voiceprint authentication, face recognition, pressing a specific button, etc., which is not limited in the present invention.

In step 102, a trigger signal is generated when the tracking system is monitored to be out of tracking target.

When the tracking system is monitored to be separated from the tracking target, the system generates a trigger signal. The trigger signal is used to trigger other modules, functions or steps. After generating the trigger signal, the system may send the trigger signal to the corresponding module.

In step 103, in response to the trigger signal, tracking system and alarm information is sent to the associated devices of the tracking system.

In response to the trigger signal, the system sends an alert message of the tracking system to an associated device of the tracking system. The related device is a device that is previously related to the tracking system. The associated device, upon receiving the tracking system alert information, may present the tracking system alert information to the user. The alarm information is information for warning to remind the user that the tracking target may be lost or an accident may occur. For example, the user may be prompted by sounding an alarm, lighting, voice prompt, or text prompt, which is not limited in the present invention.

In one example, the association device may be a smartphone that has been associated with a child tracking watch. When a trigger signal is received, the child tracking watch may send an alert message to a parent's smartphone. The parents can receive and check the alarm information of the watch through the smart phone to remind the parents that the child is possibly lost or has an accident.

Optionally, the method may further include: in response to a trigger signal, performing one or more of: transmitting location information of the tracking system to associated devices of the tracking system; taking a picture and storing the picture; and recording and saving the recorded audio.

In response to the trigger signal, the system may take a single or continuous shot. Taking a picture can capture a picture of the environment surrounding the tracking system and possibly of a malicious person. After the picture taking is complete, the system may save the taken picture. When an accident occurs to the tracking target, the pictures which are saved in the tracking system and taken when the tracking target is separated from the tracking target are helpful for finding the tracking target.

In response to the trigger signal, the system may record. The recording is capable of recording sounds in the environment surrounding the tracking system. After the recording is complete, the system may save the recorded recording audio. When an accident occurs to the tracking target, the recorded audio recorded when the tracking target is separated from the tracking target and stored in the tracking system is helpful for searching the tracking target.

In response to the trigger signal, the system may send location information to the associated device. The position information may be obtained through a positioning system such as a Global Positioning System (GPS), a beidou satellite navigation system, an a-GPS positioning system, a Wi-Fi positioning system, and a base station positioning system, which is not limited in the present invention. After receiving the position information of the tracking system, the associated device can show the position of the tracking system to the user, so that the user is helped to find the tracking target.

The system may only perform one of the above-mentioned photographing, recording, and sending location information, or may perform two or all of them in any combination, which is not limited in this disclosure.

Optionally, the method may further include: the photo and/or recorded audio is sent to the associated device.

After the photo capture is complete, the system may send the photo to the associated device. The associated device, upon receiving the photograph sent by the tracking system, may present the received photograph to the user. When an accident occurs to the tracking target, the photo is viewed through the associated equipment, so that the tracking target can be found.

After the recording is complete, the system may send the recorded audio to the associated device. After receiving the recording audio sent by the tracking system, the associated device may play the received recording audio to the user. When the tracking target is unexpected, the recorded audio is listened through the associated equipment, so that the tracking target can be found.

Optionally, the method may further include: and receiving and storing the second downlink signal of the area in response to the trigger signal.

In response to the trigger signal, the system may receive a second downlink signal of the region. After receiving the signal, the system may save the received second downlink signal. When the tracking target is unexpected, the second downlink signal which is stored in the tracking system and is received when the tracking target is separated is helpful for searching the tracking target.

Optionally, the method may further include: and sending the second downlink signal to the associated equipment.

After receiving the signal, the system may send the received second downlink signal to the associated device. The associated device may store the second downlink signal after receiving the second downlink signal sent by the tracking system. When the tracking target is unexpected, the second downlink signal in the associated equipment can be provided to law enforcement departments and telecom operators for analysis, so that the tracking target can be found.

In summary, in the tracking method based on the wireless network according to the embodiment of the present invention, the alarm information is sent when the tracking system is separated from the tracking target, so that the user can be reminded and warned when the tracking target is lost or an accident occurs.

Fig. 2 shows a schematic flow diagram of a wireless network based tracking method according to another embodiment of the invention. As shown in fig. 2, an embodiment of the present invention provides a tracking method based on a wireless network, including the following steps:

step 201, receiving a first downlink signal of an area where a tracking system is located;

step 202, determining an uplink signal frequency band of an area according to a first downlink signal;

step 203, monitoring whether the tracking system fixed on the tracking target is separated from the tracking target;

step 204, when the tracking system is monitored to be separated from the tracking target, generating a trigger signal;

step 205, in response to the trigger signal, capturing and storing an uplink signal on a nearby uplink signal frequency band; and

in response to the trigger signal, an alert message of the tracking system is sent to the device associated with the tracking system, step 206.

in step 201, a first downlink signal of an area where a tracking system is located is received.

The tracking system receives a first downlink signal of an area in which the tracking system is located. The tracking system may enter different cells as the tracking target moves, and the frequency bands used by different cells may be different. The system continuously receives the first downlink signal of the cell where the system is currently located. The downlink signal can be used for determining the network system of the wireless communication system in the area and the frequency band of the uplink signal.

In step 202, the uplink signal frequency band of the area is determined according to the first downlink signal.

After receiving the first downlink signal of the area, the system determines the uplink signal frequency band of the area according to the first downlink signal. For example, for a TDD system, uplink signals and downlink signals are in the same frequency band; for FDD systems, the uplink signal is matched in pairs with the downlink signal. Therefore, no matter which wireless communication system network system is adopted, the frequency band of the uplink signal can be determined through the frequency band of the downlink signal after the frequency band of the downlink signal is acquired.

Step 203 may refer to step 101 above and will not be described further herein.

Step 204 may refer to step 102 above and will not be described further herein.

In step 205, in response to the trigger signal, the uplink signal on the nearby uplink signal frequency band is captured and saved.

The system adjusts its own receiving frequency range to the frequency range of the current area according to the uplink signal frequency band determined in step 202. When receiving the trigger signal, the system starts signal capture, that is, continuously receives one or more uplink signals on the uplink signal frequency band near the tracking system. In an example, the grabbing of the uplink signal may be performed by using a signal receiver such as a zero intermediate frequency receiver or a low intermediate frequency receiver, which is not limited by the present invention. And after the signal capture is finished, the system stores the captured uplink signal. When the tracking target is unexpected, the captured uplink signal which is stored in the tracking system and is separated from the tracking target can be provided to law enforcement departments and telecom operators for analysis, the captured uplink signal may contain uplink information of a wireless terminal (such as a mobile phone) of a malicious person, and the information of the malicious person can be obtained by analyzing the uplink information of the wireless terminal of the malicious person, so that the tracking target can be searched.

Optionally, the method may further include: and transmitting the uplink signal to the associated equipment.

After the signal capture is completed, the system may send the captured uplink signal to the associated device. The associated device may store the uplink signal after receiving the uplink signal sent by the tracking system. When the tracking target is unexpected, the uplink signal in the associated equipment can be provided for law enforcement departments and telecom operators to be analyzed, and the tracking target searching is facilitated.

Step 206 may refer to step 103 above and will not be described further herein.

Optionally, sending the alarm information of the tracking system to the associated device of the tracking system may further include: generating frequency band avoidance information according to the uplink signal frequency band; and determining the frequency band and/or the transmission time used for transmission according to the frequency band avoiding information.

The system generates band avoidance information based on the uplink signal band determined in step 202. When the system sends the alarm information to the associated device, the system may select the uplink signal frequency band and/or the sending time different from the uplink signal frequency band being grabbed according to the frequency band avoiding information to send, so as to avoid interference to the grabbing of the uplink signal.

In summary, in the tracking method based on the wireless network according to the embodiment of the present invention, by sending the alarm information when the tracking system is separated from the tracking target, the user can be reminded and warned when the tracking target is lost or an accident occurs; by capturing and storing the nearby uplink signal when the tracking system is separated from the tracking target, the user can acquire the information of a possible malicious person when the tracking target is lost or an accident occurs, and the tracking target is favorably searched.
