However, those of ordinary skill in the art can understand that in each embodiment of the application, many technical details are provided for readers to better understand the application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in this application can also be realized. The division of the following embodiments is for the convenience of description, and should not constitute any limitation to the specific implementation of the present application, and the embodiments can be combined and referred to each other on the premise of no contradiction.

In order to facilitate the understanding of the embodiments of the present application, firstly, relevant information of the tracker is introduced here.

The tracker is a portable positioning device, the tracker is small in size and light in weight. Trackers can be worn, such as locating watches or bracelets worn on children, locating collars and locating anklets worn on pets, etc. Trackers can also be attached and installed on other items, such as crutches installed on the carrier , on a wheelchair, sewn into the pocket of the wearer's clothes, etc.

The tracker is inserted with a SIM card or has a built-in ESIM card. It can communicate with the IoT server through the base station to realize the connection with the tracker client. The tracker searches the satellite to obtain its own position information during positioning, and reports the position information to the IoT server through the base station. After that, the networked server reacquires its own location information at regular intervals, and reports it to the IoT server through the base station. Users can view the client corresponding to the tracker in real time, and view the tracker, that is, the real-time location and travel trajectory information of the tracker carrier.

An embodiment of the present application relates to a positioning method applied to a tracker. The implementation details of the positioning method in this embodiment are described in detail below, and the following content is only implementation details provided for easy understanding, and is not necessary for implementing this solution.

The specific flow of the positioning method in this embodiment may be shown in FIG. 1 , including step 101 , step 102 , step 103 and step 104 .

Step 101 , check whether there is a communication device supporting connection with the tracker, if yes, execute step 102 , otherwise, execute step 104 .

Specifically, when the tracker reports its own location information to the server, it may first detect whether there is a communication device that supports connection with the tracker. The communication device that supports the connection with the tracker can be connected with the tracker to assist the tracker to report its own location information.

In an example, the communication device may be a Wi-Fi device, and the Wi-Fi device may cover Wi-Fi signals to the surroundings for the surrounding devices to connect and communicate with the base station in a wired or wireless manner.

For example: Wi-Fi equipment can be indoor or outdoor fixed customer premise equipment (Customer Premise Equipment, referred to as: CPE), CPE can be connected to an external power supply, the power is very large, the Wi-Fi signal strength is strong, high stability, good quality, The Wi-Fi signal coverage is also great.

Another example: the Wi-Fi device can be a portable Wi-Fi device (User Wi-Fi, referred to as: UFi), and the UFi can have a built-in large-capacity battery, which can be carried around, has higher flexibility, and is more convenient to use.

In an example, the communication device may be a Bluetooth device, and the Bluetooth device may cover a Bluetooth local area network to the surroundings for connection of surrounding devices and communicate with the base station through wired or wireless Bluetooth.

In an example, the tracker can first determine whether it has a bound communication device. If the tracker is not bound to any communication device or cannot find the bound communication device, then check whether there is support for connecting with the tracker. If the bound communication device can be found, continue to use the bound communication device to prevent the tracker from occupying and using multiple communication devices at the same time, and save the communication resources of the communication device.

In an example, the tracker detects a communication device that supports connection with the tracker may be implemented through the steps shown in FIG. 2 , specifically including step 201 and step 202 .

Step 201, scan the communication devices around the tracker to obtain the unique identifier of each communication device.

In a specific implementation, when the tracker detects whether there is a communication device that supports connection with the tracker, it can scan the communication devices around the tracker, for example, scan the wireless network information around the tracker to obtain the unique identifier of each communication device. The unique identifier may indicate information such as the identity of the communication device.

In an example, the tracker can obtain the Basic Service Set Identifier (BSSID for short) of each communication device, and use the BSSID as the unique identifier of the communication device.

Step 202, according to the unique identifier of each communication device, determine the communication device that supports binding with the tracker.

In a specific implementation, after the tracker obtains the unique identifier of each communication device, it can send the unique identifier of each communication device to the server, and the server will query whether these communication devices support binding with the tracker, and inform the tracker of support A communication device bound to the tracker. The communication device supporting the connection with the tracker can be detected more quickly and accurately according to the unique identifier of each communication device.

Step 102, sending a binding request to the communication device to bind with the communication device.

Specifically, after the tracker detects a communication device that supports connection with the tracker, it can establish communication with the communication device and bind with the communication device. Establishing a binding relationship can make the communication between the tracker and the communication device more accurate, reliable and secure.

In an example, the tracker detects that there are several communication devices supporting connection with the tracker, and may select the communication device with the strongest signal among the communication devices supporting connection with the tracker for binding.

In an example, the tracker can establish a communication connection with a communication device that supports connection with the tracker through Wi-Fi direct connection, Bluetooth, Zifeng protocol, infrared and other communication methods, and bind to the communication device.

For example: the communication device that supports the connection with the tracker is a CPE, and the tracker can establish a communication connection with the CPE through Wi-Fi direct connection and bind with the CPE.

Another example: the communication device that supports connection with the tracker is a Bluetooth device, and the tracker can access the Bluetooth local area network of the Bluetooth device, establish a communication connection with the Bluetooth device, and bind with the Bluetooth device.

In a specific implementation, the tracker can store the unique identifier (such as BSSID) of the communication device, and send its own identity document (ID for short) to the communication device for storage, thereby realizing the communication between the tracker and the communication device. binding.

Step 103, sending the location information of the tracker to the bound communication device, so that the bound communication device periodically reports the location information to the server.

Specifically, after the tracker is bound to a communication device that supports connection with the tracker, it can send the tracker's location information to the bound communication device, so that the bound communication device can periodically report the location information to the server. Considering that the process of the tracker locating itself to obtain location information and reporting location information to the server consumes a lot of power, if the tracker reports location information frequently, the power consumption will be very large, resulting in a relatively short battery life of the tracker. If the location information is not available, the location information cannot be reported in time, and the real-time performance is not good. The tracker in the embodiment of the present application can report location information by supporting communication devices connected to the tracker, reduce the power consumption of the tracker itself, and support high-frequency reporting of location information while greatly increasing the battery life of the tracker, thereby improving the location. The real-time reporting of information improves the user experience.

In a specific implementation, the tracker can send the ID of the tracker, the location information of the tracker, the address of the server, and the frequency of reporting to the server to the bound communication device, so that the bound communication device can address and the frequency of reporting to the server, and periodically report the location information of the tracker to the server.

In one example, the frequency of reporting to the server is once every 15 minutes, and the tracker sends the ID of the tracker, the location information of the tracker, the address of the server, and the frequency of the reporting server to the bound communication device for the The bound communication device reports the location information of the tracker to the server every 15 minutes.

In one example, after the tracker sends its own location information to the bound communication device, it can enter a dormant state, and send a heartbeat packet to the bound communication device at a preset heartbeat cycle.

For example, the tracker sends a heartbeat packet to the bound communication device with a preset heartbeat period, which can be implemented through the steps shown in FIG. 3 , including step 301, step 302, step 303 and step 304.

Step 301 , if the preset heartbeat period is reached, check whether the bound communication device can be scanned, if so, execute step 304 , otherwise, execute step 302 .

Specifically, after the tracker sends location information to the bound communication device, it immediately enters a dormant state. When the preset heartbeat period is reached, it can detect whether the bound communication device can be scanned to judge the tracker itself. The relative position to the bound communication device. Wherein, the preset heartbeat cycle can be set by those skilled in the art according to actual needs, which is not specifically limited in this embodiment of the present application.

In an example, the preset heartbeat period can be longer than the reporting frequency to the server. For example, if the reporting frequency is 20 minutes, the preset heartbeat period is 30 minutes, that is, the tracker detects whether the bound designated communication equipment.

Step 302, reacquiring location information.

Specifically, if the tracker cannot scan the bound communication device, it means that the tracker has left the signal coverage of the bound communication device, that is, the position of the tracker has changed greatly, and the tracker can reacquire its own location information.

Step 303, periodically report the reacquired location information to the server.

Specifically, after the tracker reacquires its own location information, it can directly and periodically report the reacquired location information to the server, so as to ensure that the server can receive the location information of the tracker.

In an example, after the tracker cannot scan the bound communication device, it can re-detect whether there is a communication device around the tracker that supports connection with the tracker. If it is detected that there is a communication device around the tracker that supports connection with the tracker , can be bound to the communication device, and periodically send the reacquired location information of the tracker to the server through the communication device.

Step 304, sending a heartbeat packet to the bound communication device.

Specifically, if the tracker can scan the bound communication device, it means that the tracker has not left the signal coverage of the bound communication device, that is, the position of the tracker has not changed, or the change is very small, and the tracker does not need to To re-obtain its own location information, it only needs to send a heartbeat packet to the bound communication device to inform the bound communication device that it is still within the signal coverage of the bound communication device.

In one example, after the tracker sends the tracker's location information to the bound communication device, it can receive the relocation instruction sent by the server in real time and enter the relocation process. The tracker relocation can be performed through the steps shown in Figure 4 The implementation specifically includes step 401 and step 402.

Step 401, if the relocation instruction sent by the server is obtained, reacquire location information according to the relocation instruction.

In a specific implementation, the server can obtain the user's operation information on the client corresponding to the tracker in real time, generate a relocation instruction according to the user's operation information on the client corresponding to the tracker, and send the relocation instruction to the tracker.

In one example, the client corresponding to the tracker includes the option "obtain real-time information of the tracker". Send to tracker.

Step 402, sending the reacquired location information to the bound communication device, so that the bound communication device periodically reports the reacquired location information to the server.

Specifically, after the tracker reacquires the location information according to the relocation instruction, it can send the reacquired location information to the bound communication device, so that the bound communication device periodically reports the reacquired location information to the server. The embodiment of the present application allows the server to forcibly start the relocation process, which allows the user to obtain the real-time location of the tracker in a more timely manner, and further improves the user experience.

Step 104, periodically report the location information to the server.

Specifically, if the tracker detects that there is no communication device supporting connection with the tracker, it can directly report the location information of the tracker to the server periodically to ensure that the server can receive the location information of the tracker.

In this embodiment, if the tracker detects a communication device that supports connection with the tracker, it will send a binding request to the communication device to bind with the communication device. Establishing a binding relationship can make the communication device between the tracker and the communication device Communication is more accurate, reliable and secure. Send the location information of the tracker to the bound communication device for the bound communication to periodically report the location information to the server; if no communication device supporting connection with the tracker is detected, periodically report to the tracker The above server reports the location information, considering that the process of the tracker itself locating and obtaining the location information and reporting the location information to the server consumes a lot of power. Short, if the tracker reports location information at a low frequency, it cannot report location information in time, and the real-time performance is not good. The tracker in the embodiment of the present application can report location information by supporting communication devices connected to the tracker, reduce the power consumption of the tracker itself, and support high-frequency reporting of location information while greatly increasing the battery life of the tracker, thereby improving the location. The real-time reporting of information improves the user experience.

Another embodiment of the present application relates to a positioning method, which is applied to a communication device. The communication device may be a Wi-Fi device, such as a CPE, UFi, etc., or a Bluetooth device. The implementation details of the positioning method of this embodiment are described in detail below. The following content is only the implementation details provided for the convenience of understanding, and is not necessary for the implementation of this solution. Figure 5 is a flow chart of the positioning method described in this embodiment, including steps 501, step 502 and step 503.

Step 501, if a binding request sent by the tracker is received, bind with the tracker.

Specifically, the communication device can receive a binding request from the tracker in real time, and if the communication device receives the binding request sent by the tracker, it can bind with the tracker. Establishing a binding relationship can make the communication between the communication device and the tracker more accurate, reliable and secure.

In an example, the communication device can establish a communication connection with the tracker through Wi-Fi direct connection, Bluetooth, Zifeng protocol, infrared and other communication methods, and bind with the tracker.

In one example, after the communication device receives the binding request sent by the tracker, it can send the unique identifier (such as BSSID) of the communication device itself to the tracker that sent the binding request, and save the tracking of sending the binding request. ID of the tracker, so as to realize the binding of the communication device and the tracker.

In one example, after the communication device obtains the ID of the tracker that sent the binding request, it can judge whether the tracker is a legal device according to the ID of the tracker, and if the tracker is a legal device, it will conduct a communication with the tracker. bound.

Step 502, receiving the location information of the tracker sent by the bound tracker.

Specifically, after the communication device is bound to the tracker sending the binding request, it can receive the location information of the tracker sent by the bound tracker in real time.

Step 503, periodically report the location information to the server.

Specifically, the server may periodically report the location information to the server after receiving the location information of the tracker sent by the bound tracker. Considering that the process of the tracker locating itself to obtain location information and reporting location information to the server consumes a lot of power, if the tracker reports location information frequently, the power consumption will be very large, resulting in a relatively short battery life of the tracker. If the location information is not available, the location information cannot be reported in time, and the real-time performance is not good. The communication device of the embodiment of the present application can be used as a bridge to receive the location information of the tracker sent by the tracker and report the location information, reduce the power consumption of the tracker itself, and support high frequency while greatly increasing the battery life of the tracker. Report location information to improve the real-time performance of location information reporting, thereby improving user experience.

In one example, the communication device can also receive the ID of the tracker, the address of the server and the frequency of reporting to the server sent by the bound tracker in real time, and according to the ID of the tracker, the address of the server and the frequency of reporting to the server, the periodic Report the location information of the tracker to the server.

In an example, the frequency of reporting to the server is once every 15 minutes, and the communication device receives the ID of the tracker, the address of the server and the frequency of the reporting server sent by the bound tracker, and reports to the server every 15 minutes Tracker location information.

In this embodiment, if the binding request sent by the tracker is received, bind with the tracker; receive the location information of the tracker sent by the bound tracker; periodically report the location to the server information. As a bridge, the communication device receives the location information of the tracker sent by the tracker and reports the location information, reduces the power consumption of the tracker itself, and supports high-frequency reporting of location information while greatly increasing the battery life of the tracker, improving location information Real-time reporting, thereby improving user experience.

In one embodiment, after the communication device receives the tracker's location information sent by the bound tracker, it can receive the heartbeat packet sent by the bound tracker in real time, and the communication device receives the heartbeat packet sent by the bound tracker. The flow of the heartbeat packet can be realized through the steps shown in FIG. 6 , specifically as follows.

Step 601, judge whether the heartbeat packet sent by the bound tracker is received within the preset time, if yes, execute step 602, otherwise, execute step 603.

Specifically, while the communication device periodically reports the location information of the bound tracker to the server, it can also determine whether it has received the heartbeat packet sent by the bound tracker within the preset time, that is, to determine whether the communication device itself Also keeps a heartbeat with the bound tracker. Wherein, the preset time may be consistent with the preset heartbeat cycle of the tracker, or the preset time may be slightly longer than the preset heartbeat cycle of the tracker, which is not specifically limited in this embodiment of the present application.

Step 602, continue to periodically report the location information to the server.

Specifically, if the communication device receives the heartbeat packet sent by the bound tracker within the preset time, that is, the heartbeat between the communication device and the bound tracker is still maintained, and the position of the bound tracker does not occur. If the change or change is small, no relocation is required, and the communication device can continue to periodically report the location information of the bound tracker to the server.

In one example, the preset time is 30 minutes. If the communication device receives the heartbeat packet sent by the bound tracker again 30 minutes after receiving the heartbeat packet sent by the bound tracker, continue Periodically report location information to the server.

Step 603, unbind from the bound tracker.

Specifically, if the communication device does not receive the heartbeat packet sent by the bound tracker within the preset time, that is, there is no heartbeat between the communication device and the bound tracker, the position of the bound tracker will If there is a big change, or the battery of the bound tracker is exhausted, if the communication device still periodically reports the location information of the bound tracker to the server, it will cause a report error, and the communication device will be disconnected from the bound tracker Binding avoids error reporting and prevents waste of communication equipment resources.

In one example, the preset time is 30 minutes. If the communication device does not receive the heartbeat packet sent by the bound tracker after 30 minutes after receiving the heartbeat packet sent by the bound tracker, then Unbind from a bound tracker.

In this embodiment, after receiving the location information of the tracker sent by the tracker, it also includes: if the heartbeat packet sent by the bound tracker is received within a preset time, continue the cycle Report the location information to the server; if the heartbeat packet sent by the bound tracker is not received within the preset time, the bound tracker will be unbound to avoid error reporting , to prevent the waste of communication equipment resources.

In one embodiment, after the communication device is bound to the tracker that sent the binding request, it can receive the initial signal strength between the tracker and the communication device sent by the bound tracker, and the bound signal strength received by the communication device The heartbeat packet sent by a given tracker includes the signal strength of the latest communication between the tracker and the communication device. The communication device can judge whether relocation is required according to the initial signal strength between the tracker and the communication device, and the signal strength of the latest communication between the tracker and the communication device. The relocation method of this embodiment can be shown in Figure 7 The steps shown are implemented, specifically including step 701 , step 702 and step 703 .

Step 701, if the difference between the initial signal strength and the signal strength of the latest communication is greater than a preset difference, instruct the bound tracker to reacquire location information.

Specifically, each time the communication device receives the heartbeat packet sent by the bound tracker, it can obtain the signal strength of the latest communication between the tracker and the communication device in the heartbeat packet, and calculate the initial signal strength and The difference between the signal strengths of the last communication, if the difference is greater than the preset difference, the communication device instructs the bound tracker to reacquire the location information. Wherein, the preset difference can be set by those skilled in the art according to actual needs, which is not specifically limited in this embodiment of the present application.

In a specific implementation, the signal coverage of some communication devices is very wide, and the tracker may also have a relatively large position change in this coverage, such as moving from the center of the signal coverage of the communication device to the edge of the coverage, while in the In the case of the center position and the case of the edge position, the signal strength between the tracker and the communication device is different. In the embodiment of this application, each time the communication device receives a heartbeat packet, it will judge the change of the signal strength The way of judging whether the bound tracker needs to be relocated can effectively improve the accuracy of the location information reported by the communication device.

In one example, if the difference between the initial signal strength and the signal strength of the latest communication is less than or equal to a preset difference, it means that the position of the tracker has changed little, and no relocation is required.

In one example, the preset difference is 10dBm, and after the communication device is bound to the tracker that sent the binding request, it receives an initial signal strength of -120dBm between the tracker and the communication device. After the communication device receives the heartbeat packet sent by the tracker, it obtains that the signal strength of the latest communication between the tracker and the communication device is -85dBm, and the communication device determines the difference between the initial signal strength and the signal strength of the latest communication If the value is 35dBm, which is greater than the preset difference, it means that the position of the tracker changes greatly and needs to be relocated, and the communication device sends a relocation instruction to the tracker.

Step 702, receiving the reacquired location information sent by the bound tracker.

Specifically, after instructing the bound tracker to reacquire the location information, the communication device may receive the reacquired location information sent by the bound tracker.

Step 703, periodically report the reacquired location information to the server.

Specifically, after receiving the reacquired location information sent by the bound tracker, the communication device may periodically report the reacquired location information to the server.

In this embodiment, after the binding with the tracker, it further includes: acquiring the initial signal strength between the tracker and the communication device sent by the bound tracker; the heartbeat packet includes the signal strength of the latest communication between the bound tracker and the communication device; after receiving the heartbeat packet sent by the bound tracker, it also includes: if the If the difference between the initial signal strength and the signal strength of the latest communication is greater than a preset difference, it indicates that the bound tracker reacquires the location information; and receives the reacquired location information sent by the bound tracker Location information: Periodically report the reacquired location information to the server. In the embodiment of the present application, by judging the change of the signal strength, it is judged whether the bound tracker needs to be relocated, and the accuracy of the location information reported by the communication device is greatly improved.
