Description

Method for saving GPS positioning power consumption and wearable device
Technical Field
The invention relates to the technical field of wearable equipment, in particular to a method for saving GPS positioning power consumption and the wearable equipment.
Background
Currently, many children telephone watches on the market use a GPS module to perform GPS positioning, so that parents can timely acquire the positions of children. Because the battery capacity of the child telephone watch is generally small, and the GPS positioning power consumption of the GPS module is also high, the GPS module cannot be started for a long time generally. In practical application, when a householder usually wants to acquire the position of a child, the child telephone watch sends a positioning instruction to the child telephone watch through a server, and then the child telephone watch starts a GPS module to perform GPS positioning.
However, since it is not known how long the child telephone watch turns on the GPS module before the positioning is successful, it is a common practice in the industry to set a fixed turn-on duration (e.g., 1 minute) for the GPS module, and turn off the GPS module if the positioning result is not obtained within the fixed turn-on duration. This approach has two drawbacks: firstly, the GPS positioning cannot be successful indoors, but the GPS module is started within a fixed starting time (such as 1 minute), so that the power consumption of the GPS positioning is wasted; secondly, in some places with weak outdoor signals, the positioning may need to be successful after exceeding the fixed opening time (for example, 1 minute and half minutes), but at this time, the GPS module is already closed, and the GPS positioning cannot be performed.

and if the GPS positioning is not successfully carried out within the second specified time length, the wearable equipment closes the GPS module.
A second aspect of an embodiment of the present invention discloses a wearable device, including:
the prediction unit is used for predicting whether the GPS positioning can be successfully carried out within the second specified time length at intervals of a first specified time length by using the prediction model after the GPS module is started; wherein the second specified time is longer than the first specified time, the prediction model comprises at least the time T for the final GPS positioning success under the historical number of connected satellites s1 and the historical average signal strength of connected satellites c1 which are collected;

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention discloses a method for saving GPS positioning power consumption and wearable equipment, which can save the GPS positioning power consumption of the wearable equipment. The following detailed description is made with reference to the accompanying drawings.
Example one
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for saving GPS positioning power consumption according to an embodiment of the present invention. As shown in fig. 1, the method may include the following steps.
101. After the GPS module is started, the wearable device predicts whether GPS positioning can be successfully carried out within a second specified time period at intervals of a first specified time period by using a prediction model; wherein the second designated duration is longer than the first designated duration, and the prediction model at least comprises the collected time T for the final GPS positioning success under the historical number of connected satellites s1 and the historical average signal strength of connected satellites c 1.
In this embodiment of the present invention, the wearable device may include various intelligent wearable devices such as a smart watch (e.g., a telephone watch), a smart bracelet, a smart foot ring, a smart ear ring, a smart necklace, a smart hat, and a smart garment, which is not limited in this embodiment of the present invention.
As an alternative embodiment, the wearer of the wearable device may actively control the wearable device to turn on the GPS module, for example, the wearer of the wearable device may actively control the wearable device to turn on the GPS module when leaving a safe area (e.g., school, cell).
Or, as another alternative, the wearable device may automatically turn on the GPS module, for example, the wearable device may actively control the wearable device to turn on the GPS module when the signal from the trusted Wi-Fi hotspot is not detected.
As another example, the wearable device may obtain that the user device sends a location request through a service device and turn on the GPS module according to the location request, for example, the wearable device may obtain that a parent of the user device (e.g., a parent's mobile phone) sends a location request through the service device (e.g., a location server) and turn on the GPS module according to the location request.
Further, the location request may carry attribute information, where the attribute information includes not only an identity of the wearable device, but also identity of the user equipment and a hotspot identity of a trusted Wi-Fi hotspot to which the user equipment is currently connected; correspondingly, after the wearable device obtains the positioning request sent by the user device through the service device, whether the identity of the user device is the same as the identity of the monitoring device configured in advance by the wearable device can be checked, if not, the wearable device can ignore the positioning request and keep the GPS module in a closed state; if the Wi-Fi hotspots are the same, the wearable device can identify whether the wearable device is currently accessed to a certain Wi-Fi hotspot, if so, further checking whether a hotspot identification (such as a mac address of the Wi-Fi hotspot) of the certain Wi-Fi hotspot currently accessed by the wearable device is the same as a hotspot identification of a trusted Wi-Fi hotspot currently accessed by the user device, if so, indicating that a wearer of the wearable device and a user to which the user device belongs are both located in the same coverage range of the Wi-Fi hotspot, and the distance between the wearer of the wearable device and the user to which the user device belongs is closer, so that the wearable device can ignore the positioning request and keep the GPS module in a closed state, and power consumption caused by starting the GPS module is reduced; if the distance between the GPS module and the GPS module is different, the distance between the GPS module and the GPS module is far, and the GPS module is started according to the positioning request, so that the accuracy of starting the GPS module can be improved.
Further, after the wearable device checks that the hotspot identification (such as the mac address of the Wi-Fi hotspot) of a certain Wi-Fi hotspot currently accessed by the wearable device is different from the hotspot identification of a trusted Wi-Fi hotspot currently accessed by the user device, and before the GPS module is turned on according to the positioning request, the following steps may be further performed:
the wearable device judges whether the current residual current of the wearable device is lower than a specified electric quantity (such as 30%), and if the current residual current of the wearable device is not lower than the specified electric quantity, the wearable device starts a GPS module according to the positioning request; on the contrary, if the power consumption is lower than the specified power, the wearable device outputs prompt information, the prompt information is used for prompting that a trusted terminal (such as a mobile phone or a tablet used by a wearer of the wearable device) is close to the wearable device for near field communication, when the trusted terminal (such as a mobile phone or a tablet used by a wearer of the wearable device) is close to the wearable device, the wearable device transmits the positioning request to the trusted terminal in a near field communication mode, and the GPS module is kept in a closed state, so that the power consumption aggravation caused by the GPS module is reduced; after the trusted terminal receives the positioning request, it may first check whether the identity of the user equipment is the same as the identity of the monitoring equipment configured in advance for wearable equipment by the trusted terminal, and if not, the trusted terminal may ignore the positioning request; if the Wi-Fi hotspots are the same, the trusted terminal can identify whether the trusted terminal is currently accessed to a certain Wi-Fi hotspot, if so, further checking whether a hotspot identification (such as a mac address of the Wi-Fi hotspot) of the certain Wi-Fi hotspot currently accessed by the trusted terminal is the same as the hotspot identification of the trusted Wi-Fi hotspot currently accessed by the user equipment, and if so, the trusted terminal can ignore the positioning request; if the positioning request is different, the trusted terminal acquires the current position information of the trusted terminal as the position information of the wearable device according to the positioning request and reports the position information to the user equipment through the service equipment, so that transfer positioning can be realized, and the GPS positioning power consumption of the wearable device is reduced.
In the embodiment of the invention, the wearable device can collect big data of the corresponding relation between the historical connection satellite number s1, the historical connection satellite average signal strength c1 and the time T used for the successful final GPS positioning in advance, and performs neural network weight training on the big data by using the principle of artificial intelligence machine learning to form a set of prediction models (such as a decision tree algorithm model), wherein the prediction models at least comprise the collected time T used for the successful final GPS positioning under the historical connection satellite number s1 and the historical connection satellite average signal strength c 1. The historical number of connected satellites s1 can also be understood as the historical minimum number of connected satellites s1, that is, the prediction model can be understood as the time T taken for the final GPS positioning to be successful under the historical minimum number of connected satellites s1 and the historical average signal strength of connected satellites c 1.
As an optional implementation manner, after the GPS module is turned on, the wearable device predicts, by using the prediction model, whether GPS positioning is successful within a second specified time period at every first specified time period, where the method includes:
after the GPS module is started, the wearable device detects the number s2 of the current connected satellites and the average signal intensity c2 of the current connected satellites of the wearable device every a first specified time (such as 5 seconds);
and judging whether the current connecting satellite number s2 is less than the historical connecting satellite number s1 (which can be understood as the historical minimum connecting satellite number s1) and/or judging whether the average signal intensity c2 of the current connecting satellite is less than the average signal intensity c1 of the historical connecting satellite; wherein the second specified time length is equal to the time T;
and if the current connecting satellite number s2 is smaller than the historical connecting satellite number s1 and/or the current connecting satellite average signal intensity c2 is smaller than the historical connecting satellite average signal intensity c1, determining that the GPS positioning is predicted not to be successful within the second specified time.
If the current connecting satellite number s2 is greater than or equal to the historical connecting satellite number s1 and the current connecting satellite average signal strength c2 is greater than or equal to the historical connecting satellite average signal strength c1, it is determined that the GPS positioning is predicted to be successful within a second specified time (e.g., 2 minutes) this time.
In the embodiment of the present invention, the prediction model may use various common machine learning approximation models. One embodiment, using a decision tree algorithm model, is illustrated below. A decision tree is a tree structure similar to a flow chart in which each tree node represents a test on an attribute and each branch represents the output of an attribute. As shown in fig. 10, it is assumed that the number of currently visible satellites is attribute 1, the number of currently connected satellites is attribute 2, the average signal strength of the currently connected satellites is attribute 3, and so on. The model is trained in a large number, and the w1, w2 and w3 parameters of each opening time point are determined to form the model, so that whether the GPS positioning can be successfully predicted by using the parameters in the prediction model when the GPS is opened next time.
102. And if the GPS positioning is not successfully carried out within the second specified time length, the wearable device closes the GPS module.
If the GPS positioning can be successfully carried out within the second specified time length, the GPS module is kept in the starting state, and whether the GPS positioning can be successfully carried out is predicted again after the next first specified time length.
In the method described in fig. 1, whether the positioning is successful within the specified time after the GPS module is turned on is predicted, and the scene in which the positioning is not successful can be predicted as early as possible, so that the GPS module is turned off to achieve the effect of saving the GPS positioning power consumption of the wearable device.
Example two
Referring to fig. 2, fig. 2 is a flow chart illustrating another method for saving GPS positioning power consumption according to an embodiment of the present invention. In the method described in fig. 2, it is assumed that the wearable device and the mobile device are both located in a building (e.g., a mall), and the wearable device is not close to the entrance of the building, the mobile device is close to the entrance of the building, and the mobile device utilizes the inertial measurement unit to locate the location information of the mobile device. For example, please refer to fig. 3, fig. 3 is a plan view illustrating an indoor environment of a building according to an embodiment of the present invention. As shown in fig. 3, the entrance of the building may be a building gate (represented by a black bold line segment), the wearable device is not close to the entrance of the building, and the mobile device is close to the entrance of the building (represented by a semicircular area representing the area close to the entrance of the building). The mobile equipment is provided with an inertia measuring unit which is used for sensing data such as acceleration, angular velocity, magnetic force, pressure and the like in the traveling process of the mobile equipment and calculating the step length and the direction by using the data so as to achieve the purpose of positioning and tracking. Before the mobile equipment enters the building, the position information with higher accuracy can be obtained by using a conventional outdoor positioning method, and the mobile equipment can be positioned and tracked by using the inertial measurement unit within a short time when entering the entrance of the building (at the moment, the mobile equipment is close to the entrance of the building), so that the indoor positioning of the mobile equipment can be realized. For example, when the mobile device is located outdoors and is close to an entrance of a building, the initial longitude and latitude may be obtained by using a GPS, and then within a short time (when the mobile device is close to the entrance of the building), such as 20 seconds, when the mobile device enters the entrance of the building, the inertial measurement unit configured to the mobile device performs estimation of the step length and the direction, so that the longitude and latitude of the mobile device indoors can be calculated by combining the initial longitude and latitude as the location information of the mobile device.
In the embodiment of the present invention, the mobile device may be a wearable device, a smart phone, a tablet computer, or other mobile devices, which is not limited in the embodiment of the present invention.
As shown in fig. 2, the method may include the steps of:
201. and the wearable device acquires that the user equipment sends a positioning request through the service equipment before the GPS module is started.
Optionally, the location request may carry attribute information, where the attribute information includes not only an identity of the wearable device, but also identity information of the user equipment and a hotspot identity of a trusted Wi-Fi hotspot accessed by the user equipment; correspondingly, after the wearable device obtains the positioning request sent by the user device through the service device, whether the identity of the user device is the same as the identity of the monitoring device configured in advance by the wearable device can be checked, if not, the wearable device can ignore the positioning request and keep the GPS module in a closed state; if the Wi-Fi hotspots are the same, the wearable device can identify whether the wearable device is currently accessed to a certain Wi-Fi hotspot in the building, if so, further checking whether a hotspot identification of the certain Wi-Fi hotspot currently accessed by the wearable device is the same as a hotspot identification of a trusted Wi-Fi hotspot currently accessed by the user device, if so, indicating that a wearer of the wearable device and a user to which the user device belongs are both located in the coverage range of the same Wi-Fi hotspot in the building, and at the moment, the distance between the wearer of the wearable device and the user to which the user device belongs is closer to each other in the building, the wearable device can ignore the positioning request and keep the GPS module in a closed state so as to reduce power consumption caused by starting the GPS module; if the distance between the wearable device and the building is not the same, the distance between the wearable device and the building is far, and the wearable device starts the GPS module according to the positioning request, so that the accuracy of starting the GPS module can be improved.
Further, after the wearable device checks that the hotspot identification (such as the mac address of the Wi-Fi hotspot) of a certain Wi-Fi hotspot currently accessed by the wearable device is different from the hotspot identification of a trusted Wi-Fi hotspot currently accessed by the user device, and before the GPS module is turned on according to the positioning request, the following steps may be further performed:
the wearable device judges whether the current residual current of the wearable device is lower than a specified electric quantity (such as 30%), and if the current residual current of the wearable device is not lower than the specified electric quantity, the wearable device starts a GPS module according to the positioning request; on the contrary, if the power consumption is lower than the specified power, the wearable device outputs prompt information, the prompt information is used for prompting that a trusted terminal (such as a mobile phone or a tablet used by a wearer of the wearable device) is close to the wearable device for near field communication, when the trusted terminal (such as a mobile phone or a tablet used by a wearer of the wearable device) is close to the wearable device, the wearable device transmits the positioning request to the trusted terminal in a near field communication mode, and the GPS module is kept in a closed state, so that the power consumption aggravation caused by the GPS module is reduced; after the trusted terminal receives the positioning request, it may first check whether the identity of the user equipment is the same as the identity of the monitoring equipment configured in advance for wearable equipment by the trusted terminal, and if not, the trusted terminal may ignore the positioning request; if the Wi-Fi hotspots are the same, the trusted terminal can identify whether the trusted terminal is currently accessed to a certain Wi-Fi hotspot, if so, further checking whether a hotspot identification (such as a mac address of the Wi-Fi hotspot) of the certain Wi-Fi hotspot currently accessed by the trusted terminal is the same as the hotspot identification of the trusted Wi-Fi hotspot currently accessed by the user equipment, and if so, the trusted terminal can ignore the positioning request; if the positioning request is different, the trusted terminal acquires the current position information of the trusted terminal as the position information of the wearable device according to the positioning request and reports the position information to the user equipment through the service equipment, so that transfer positioning can be realized, and the GPS positioning power consumption of the wearable device is reduced.
The trusted terminal can acquire the current position information of the trusted terminal based on a traditional indoor positioning method.
202. The wearable device starts the GPS module according to the positioning request.
203. After the GPS module is started, the wearable device predicts whether GPS positioning can be successfully carried out within a second specified time period at intervals of a first specified time period by using a prediction model; wherein the second designated duration is longer than the first designated duration, and the prediction model at least comprises the collected time T for the final GPS positioning success under the historical number of connected satellites s1 and the historical average signal strength of connected satellites c 1.
204. And if the GPS positioning is not successfully carried out within the second specified time length, the wearable device closes the GPS module.
205. The wearable device performs Bluetooth searching, and determines the mobile device from the peripheral devices obtained through Bluetooth searching.
206. The wearable device acquires the position information of the mobile device, the distance between the wearable device and the mobile device and the relative direction between the wearable device and the mobile device in a Bluetooth mode.
In the embodiment of the present invention, for example, the wearable device may acquire the location information of the mobile device, the distance between the wearable device and the mobile device, and the relative direction between the wearable device and the mobile device by using a bluetooth 5.1 method. Wherein, bluetooth 5.1 mode has the range finding and surveys the direction function, and the precision reaches centimetre level.
207. The wearable device obtains the position information of the wearable device according to the position information of the mobile device, the distance between the wearable device and the mobile device and the relative direction between the wearable device and the mobile device.
It can be understood that, in step 207, the wearable device uses the mobile device as a reference object, and on the premise that the location information of the mobile device is known, the location information of the wearable device can be calculated according to the distance between the wearable device and the mobile device and the relative direction between the wearable device and the mobile device.
208. The wearable device sends location information including the wearable device to the user device through the service device.
As an optional implementation manner, when the user equipment receives the location information of the wearable device reported by the trusted terminal through the service device and also receives the location information of the wearable device sent by the wearable device to the user equipment through the service device, the user equipment may be subject to the fact that the wearable device sends the location information including the wearable device to the user equipment through the service device; or, the user equipment may also select, as the final location information of the wearable device, location information of an intermediate point of the location information of the wearable device, which is sent to the user equipment by the service device through both (i.e., the trusted terminal and the wearable device), so that the location accuracy of the wearable device may be improved.
209. The wearable device performs a Wi-Fi scanning operation to obtain a first set of Wi-Fi.
It is to be understood that the first set of Wi-Fi points may be a set of Wi-Fi hotspots resulting from the scanning operation.
210. The wearable device stores the position information of the wearable device and the first Wi-Fi set in a correlated mode to a service platform of a building, so that the service platform receives a second Wi-Fi set reported by a terminal located in the building, and when the overlapping degree of the second Wi-Fi set and the first Wi-Fi set is higher than a specified threshold value, the service platform pushes the position information of the wearable device serving as the position information of the terminal to the terminal.
The specified threshold may be set as needed, for example, the specified threshold may be set to 96%, and the embodiment of the present invention is not limited.
In step 209 to step 210, positioning data can be efficiently provided for the indoor terminal, so that the calculation amount of indoor Wi-Fi positioning can be reduced.
In the method described in fig. 2, whether the positioning is successful within the specified time after the GPS module is turned on is predicted, and the prediction can be performed as early as possible for a scene in which the positioning is not successful, so that the GPS module is turned off to achieve the effect of saving the GPS positioning power consumption of the wearable device.
In addition, in the method described in fig. 2, positioning data can be efficiently provided for indoor terminals, so that the amount of calculation for indoor positioning can be reduced.
Furthermore, in the method described in fig. 2, the positioning accuracy of the wearable device may be improved.

Referring to fig. 4, fig. 4 is a flowchart illustrating another method for saving GPS positioning power consumption according to an embodiment of the present invention. In the method described in fig. 4, as shown in fig. 3, it is assumed that the wearable device and the mobile device are both located in a certain building (e.g., a mall) and the wearable device is not close to the entrance of the building, the mobile device is close to the entrance of the building, and the mobile device utilizes the inertial measurement unit to locate the position information of the mobile device. As shown in fig. 4, the method may include the steps of:
401. and the wearable device acquires that the user equipment sends a positioning request through the service equipment before the GPS module is started.
