With the above figures, there are shown specific embodiments of the present application, which will be described in more detail below. The drawings and written description are not intended to limit the scope of the inventive concepts in any manner, but rather to illustrate the concepts of the application by those skilled in the art with reference to specific embodiments.
Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
At present, in order to satisfy the positioning functions of various APPs in mobile terminal equipment, the terminal equipment can complete positioning through two positioning modes, namely satellite positioning and network positioning.
In network positioning, taking base station positioning as an example, the SIM card of the terminal device may obtain the location of the terminal device through a specific algorithm by combining with the known location of the base station through signal differences between the SIM card and different base stations in a registered state. However, this method depends on the network, and when the network connection fails or the positioning credential is invalid, the positioning may fail.
In the satellite positioning, after a satellite signal captured by terminal equipment, the change rate of a pseudo distance and a distance from the terminal equipment to a satellite can be measured, data such as satellite orbit parameters and the like can be demodulated, according to the data, the terminal equipment can perform positioning calculation according to a positioning calculation method, and the geographic position of the terminal equipment is calculated. However, this method needs to be in an open and unobstructed area for successful positioning, i.e. the method depends on the environment of the area where the terminal device is located.
When satellite positioning and network positioning are invalid, how to acquire positioning information so as to improve user experience is an urgent problem to be solved.
Therefore, the positioning method provided by the application can be used for acquiring the positions and signal strengths of other terminal equipment through communication with other terminal equipment, such as bluetooth communication, and determining the positions according to the positions and the signal strengths to realize positioning, so that the user experience is improved.
In one possible implementation, the Signal Strength may be a Received Signal Strength Indicator (RSSI).
The RSSI is mainly used for measuring the distance between a transmitter and a receiver, and the RSSI ranging is based on the principle that radio waves or sound waves are transmitted in a medium, and the signal power is attenuated along with the propagation distance. According to the transmitting power of the known signal of the beacon node and the signal power received by the node, the distance between the nodes can be calculated through an attenuation model between the signal and the distance.
Because the signal is influenced by distance and obstacles in the process of signal propagation, the power intensity of the signal is attenuated along with the signal, and the precision is indirectly influenced. Good accuracy is required and this is only reflected by short distances.
For ease of understanding, an application scenario to which the embodiment of the present application is applied is described below with reference to fig. 1.
Fig. 1 is a schematic diagram of an application scenario applicable to the present application, and referring to fig. 1, the application scenario includes: terminal device 101, terminal device 102, terminal device 103, and terminal device 104. The terminal device 101, the terminal device 102, the terminal device 103, and the terminal device 104 can communicate by bluetooth.
Taking the terminal device 101 for positioning as an example, the terminal device 101 may establish a communication connection with the terminal device 102, the terminal device 103, and the terminal device 104, and then may determine the position of the terminal device 101 through the acquired signal strength and position of the terminal device 102, the terminal device 103, and the terminal device 104, so as to implement positioning of the terminal device 101.
It is understood that the number of the terminal devices 101, 102, 103 and 104 may be multiple, and is not shown in the figure.
The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following embodiments may exist independently or in combination, and the same or similar concepts or processes may not be described in detail in some embodiments.

It is understood that the first terminal device may also establish a communication connection directly with the at least one second terminal device to achieve positioning. That is to say, the first terminal device does not need to establish a communication connection with the second terminal device when the satellite positioning and/or the network positioning fails, that is, the positioning method of the present application may be used as an optional positioning manner, for example, the first terminal device may preferentially use the positioning manner of the present application when performing the positioning, which is not limited by the present application.
For example, the first terminal device may establish a communication connection with a bluetooth module of at least one second terminal device via the bluetooth module.
S202, obtaining first signal strength and position of at least one second terminal device.
After the first terminal device establishes a communication connection with at least one second terminal device, the first terminal device may obtain a first signal strength and a position of the at least one second terminal device to determine the position of the first terminal device.
For example, the first signal strength may be RSSI, or may be other representations, and the location may be one or more of longitude, latitude, altitude, and other dimensions, which is not limited in this application.
S203, determining the position of the first terminal device according to the first signal strength and the position of at least one second terminal device.
The way in which the first terminal device determines its location from the first signal strength and the location of the at least one second terminal device may be, for example: and the first terminal equipment determines the relative distance between the first terminal equipment and each second terminal equipment according to the first signal strength, and then determines the position of the first terminal equipment according to the relative distance and the positions of the second terminal equipment.
In this embodiment, the first terminal device establishes a communication connection with at least one second terminal device, then obtains the first signal strength and the position of the at least one second terminal device, and determines the position of the first terminal device according to the first signal strength and the position of the at least one second terminal device. Even if the satellite positioning of the first terminal equipment is invalid and the network signal is poor, the first terminal equipment can realize positioning through the positions of the terminal equipment nearby the first terminal equipment, and the user experience is improved.
Next, S203 in the above embodiment is described by an embodiment, that is, the first terminal device determines the location of the first terminal device according to the first signal strength and the location of the at least one second terminal device.
Fig. 3 is a schematic flowchart of another positioning method provided in the second embodiment of the present application, where the method may be executed by a first terminal device, and with reference to fig. 3, the method includes the following steps.
S301, determining a relative distance between the first terminal device and each second terminal device according to the first signal strength of at least one second terminal device.
After the first terminal device obtains the first signal strength and the position of the at least one second terminal device, the first key device may determine a relative distance between the first key device and each second terminal device according to the first signal strength of the at least one second terminal device.
Specifically, the first terminal device may obtain the environment attenuation parameter and a second signal strength corresponding to the preset distance, and then determine the relative distance between the first terminal device and the second terminal device according to the first signal strength, the environment attenuation parameter, and the second signal strength.
Illustratively, the first signal strength is RSSI, and the first terminal device may calculate the relative distance according to the following formula:
Figure BDA0003856074400000081
wherein d is a relative distance between the first terminal device and each second terminal device, RSSI is a first signal strength, and a unit is dBm (decibel-milliwatt), a is a second signal strength corresponding to a preset distance, and the second preset distance may be 1m (meter), and the second signal strength is a signal strength at a distance of 1m between the terminal devices. n is an environmental attenuation parameter and can be between 3.25 and 4.5.
S302, determining the position of the first terminal device according to the relative distance between the first terminal device and each second terminal device and the position of at least one second terminal device.
The first terminal device may determine the location of the first terminal device based on the relative distance and the location of the at least one second terminal device.
In a possible implementation manner, when the number of the second terminal devices is 1, the location of the second terminal device may be determined as the location of the first terminal device.
In a possible implementation manner, when the number of the second terminal devices is 1 and the relative distance is less than or equal to the preset threshold, the position of the first terminal device may be determined from the position of the second terminal device, so that the accuracy of the positioning may be further improved.
In a possible implementation manner, when the number of the second terminal devices is multiple, the first terminal device may determine a circle corresponding to each second terminal device, where a center of the circle is a position of the second terminal device, and a radius of the circle is a relative distance between the second terminal device and the first terminal device. And then determining the intersection points of the circles, and determining the position of the first terminal device according to the positions of the intersection points of the circles.
Specifically, the following describes in detail the determination of the position of the first terminal device when the number of the second terminal devices is plural, by taking the number of the second terminal devices as 2 and 3 as examples.
(1) The number of the second terminal devices is 2
Taking the position of the second terminal device as the center of the circle, and taking the relative distance between the second terminal device and the first terminal device as the radius, determining 2 circles corresponding to the second terminal device, where the circles corresponding to the two second terminal devices are as shown in fig. 4, and since the relative distance between the terminal devices is not too large, for convenience of calculation, the centers of the two circles may be regarded as being on a horizontal plane, and it can be understood that fig. 4 is a top view of the circles corresponding to the two second terminal devices.
Then, the position of the first terminal device may be a position at which any one of the two intersections in fig. 4 is located, i.e., point a and point B. The first terminal device may determine the location of the point a or the point B as its location.
(2) The number of the second terminal devices is 3
Similarly, since the relative distance between each terminal device is not too large, for convenience of calculation, the centers of the three circles may be regarded as being on a horizontal plane, and it can be understood that fig. 5 is a top view of the circles corresponding to the three second terminal devices.
The position of the first terminal device may then be the position of the intersection point in fig. 5, i.e. point D. The first terminal device may determine the location of the point D as its location.
Specifically, the intersection point of the two cases may be determined by the expression of each circle through each circle center and radius, then the coordinates of the two intersection points are obtained according to the intersection point calculation method, and the first terminal device may determine the position of the intersection point according to the coordinates of the intersection point.
Therefore, the more the number of the second terminal devices is, the more accurate the positioning is.
In the application, the first terminal device can determine the relative distance between the first terminal device and each second terminal device according to the first signal strength of at least one second terminal device, and then determine the position of the first terminal device according to the relative distance between the first terminal device and each second terminal device and the position of at least one second terminal device, so that the positioning is relatively accurate, even if the satellite positioning of the first terminal device fails, and when the network signals are poor, the first terminal device can also pass through the positions of the terminal devices nearby the first terminal device, the positioning is realized, and the user experience is improved.
Next, S201 in the first embodiment is described through a third embodiment, that is, a detailed description is given of establishing a communication connection between the first terminal device and at least one second terminal device.
Fig. 6 is a flowchart of another positioning method provided in the third embodiment of the present application, where the method may be executed by a first terminal device, and with reference to fig. 6, the method includes the following steps.
And S601, sending the broadcast information.
Taking the example that the first terminal device communicates with the second terminal device through the bluetooth module, the first terminal device may send broadcast information through the bluetooth module, where the broadcast information may be a communication signal or other form of information, and the application is not limited to this.
S602, receiving device information corresponding to the broadcast information sent by the plurality of communication devices.
After each communication device in the bluetooth communication range receives the broadcast information, the device information corresponding to the broadcast information is sent to the first terminal device, for example, the device information may be a bluetooth name, so as to notify that each communication device of the refrigerator can perform communication.
S603, determining at least one second terminal device in the plurality of communication devices according to the device information.
In a possible implementation manner, the second terminal device may be provided with an auxiliary positioning identifier, and optionally, the auxiliary positioning identifier may be an attribute identifier of the bluetooth module.
The auxiliary positioning identifier is used for determining that the second terminal device supports an auxiliary positioning function, and the user can turn on or off the auxiliary positioning function, and if the user turns on the function, the device information of the second terminal device includes the auxiliary positioning identifier.
Then, the first terminal device may determine, among the plurality of communication devices, a communication device whose device information includes the auxiliary positioning identifier, and then determine, as the second terminal device, the communication device whose device information includes the auxiliary positioning identifier.
After determining the at least one second terminal device, for example, the first terminal device may establish a communication connection with the at least one second terminal device through the bluetooth module, and the first terminal device may pair with a bluetooth name corresponding to the at least one second terminal device through the bluetooth name of the bluetooth module of the first terminal device to establish the communication connection.
In this embodiment, the first terminal device may transmit the broadcast information and receive device information corresponding to the broadcast information transmitted by the plurality of communication devices, and then the first terminal device determines at least one second terminal device among the plurality of communication devices according to the device information, so that the first terminal device may exclude communication devices other than the non-terminal devices and communicate with the second terminal device to obtain the first signal strength and the position of the second terminal device.
