It should be noted that the structure shown in fig. 1 is merely an example, and the embodiment of the present application is not limited thereto.

Based on the above description, fig. 2 illustrates an exemplary flow of a method for controlling a smart device according to an embodiment of the present application, where the flow may be executed by an apparatus for controlling a smart device. The method for controlling the smart device may be performed by the first smart device, or may be performed by a chip or a circuit provided in the first smart device. The following describes an example of a method for controlling the smart device performed by the first smart device.

As shown in fig. 2, the process specifically includes:

in step 201, when the first intelligent device detects an ultra wideband communication UWB signal of the second intelligent device, the first intelligent device determines the position information of the second intelligent device through a set position measurement algorithm.

In this embodiment of the present application, the first intelligent device is a device having an operation function and a UWB function, and the second intelligent device is a device having a UWB function. Illustratively, the first intelligent device may be a smart phone, a tablet computer, a smart television, a smart refrigerator, a smart air conditioner, a smart dressing mirror or other devices with certain operation capability (or data processing capability) and supporting UWB functions; the second intelligent device can be a device supporting UWB functions, such as an intelligent television, an intelligent refrigerator, an intelligent air conditioner, an intelligent curtain, an intelligent fan, an intelligent sound box, an intelligent dressing mirror, an intelligent mobile phone, a tablet personal computer or an intelligent bracelet. When the first intelligent device detects a UWB signal transmitted by the second intelligent device through the UWB antenna, the position information of the second intelligent device can be determined through a set position measurement algorithm. Specifically, the UWB technology is an ultra wide band communication technology, and uses non-sinusoidal narrow pulses of nanosecond to microsecond order to transmit data, which has the characteristics of strong anti-interference performance, high transmission rate, low power consumption, and the like, so that the UWB technology can play an important role in the field of spatial positioning, and can accurately position a certain spatial object with UWB function, so that based on the characteristics of the UWB technology, the UWB technology is gradually applied to spatial positioning of smart home scenes, so as to provide more convenient service for indoor spatial object positioning of smart home scenes (such as positioning of smart home devices).

If the first intelligent device is an intelligent home device at a fixed position, the trusted position range is a three-dimensional space region where the first intelligent device is located. The intelligent household equipment at the fixed position can comprise equipment such as an intelligent television, an intelligent refrigerator, an intelligent air conditioner or an intelligent dressing mirror; the three-dimensional space region is used for determining whether to allow the second intelligent device to connect to the wireless network where the first intelligent device is located. Thus, authentication of the intelligent device entering the three-dimensional space region can be completed through the three-dimensional space region, and when the second intelligent device is located in the three-dimensional space region, the second intelligent device can be considered as a trusted device, and the second intelligent device is allowed to be connected with a wireless network where the first intelligent device is located. If the second intelligent device is determined to be outside the three-dimensional space region, the second intelligent device is considered to be an untrusted device, and the second intelligent device is not allowed to connect to the wireless network where the first intelligent device is located. When the first intelligent device is an intelligent home device, firstly, one UWB antenna is respectively deployed at m position points of the first intelligent device according to a set angle, and two UWB antennas are deployed at the (m+1) th position point of the first intelligent device. Wherein the distance between the two UWB antennas is no greater than half a wavelength of the UWB signal. Then, through UWB antennas of m position points, and according to UWB ranging basic principles, at least one position information of the second intelligent device can be accurately determined. Meanwhile, through two UWB antennas deployed on the (m+1) th position point of the first intelligent device, a straight line formed by connecting the two UWB antennas is perpendicular to a plane where the first intelligent device is located, for example, the first intelligent device is taken as an intelligent television, two UWB antennas are deployed on the (m+1) th position point on the intelligent television, the straight line formed by connecting the two UWB antennas is perpendicular to the plane where the intelligent television is located (namely, the screen surface of the intelligent television), and the like, based on an AOA (Angle of Arrival) positioning algorithm and the like, the position direction of the second intelligent device relative to the first intelligent device can be accurately determined through the two UWB antennas, so that the position information matched with the position direction can be determined from at least one position information of the second intelligent device, and the position information matched with the position direction is determined as the position information of the second intelligent device, and therefore accurate space positioning of the second intelligent device is achieved. Wherein m is an integer of 3 or more.

The basic principle Of UWB ranging is divided into TOF (Time Of Flight)Ranging) or TW-TOF (Two-Way Time Of Flight) or the like. The TOF ranging algorithm mainly uses the time of flight of signals between two asynchronous transceivers (transceivers) to measure the distance between nodes. For example, the time interval between the data packet sent by the sending end and the response received by the receiving end is denoted as TTOT, and the time interval between the data packet received by the receiving end and the response sent by the receiving end is denoted as TTAT, so that the data packet unidirectionally flies in the airThen, according to the time of unidirectional flight TTOF and the propagation speed of electromagnetic waves, the distance d=c×ttof between the two points can be calculated. Wherein, C is the speed of light. Each module in the TW-TOF ranging algorithm generates an independent time stamp from start-up. The transmitter of the module a transmits a pulse signal of a request property at Ta1 on its timestamp, which is received by the module B at its own timestamp Tb1, after which the module B waits for a response moment, transmits a signal of a response property to the module a at Tb2, which is received by the module a at its own timestamp Ta 2. Thus, the flight time of the pulse signal between the two modules can be calculated to determine the flight distance S between the two modules, i.e. S=C× [ (Ta 2-Ta 1) - (Tb 2-Tb 1) ]. Wherein, C is the speed of light.

An example, taking a first intelligent device as an intelligent dressing mirror as an example, as shown in fig. 3, is a schematic structural diagram of the intelligent dressing mirror provided in the embodiment of the present application. According to a certain angle, each of 3 position points on the intelligent dressing mirror is provided with one UWB antenna, meanwhile, the 4 th position point is provided with two UWB antennas, a straight line formed by connecting the two UWB antennas is perpendicular to the mirror surface of the intelligent dressing mirror, the distance between the two UWB antennas is not more than half wavelength of UWB signals, for example, each of three position points A, B, C is provided with one UWB antenna, the two UWB antennas are arranged at the position point D based on the thickness of the intelligent dressing mirror, the straight line formed by connecting the two UWB antennas is perpendicular to the mirror surface of the intelligent dressing mirror, and the distance between the two UWB antennas is not more than half wavelength of UWB signals. Then, UWB days through A, B, C three-position pointsLine and determining at least one location information of a second smart device (such as a smart air conditioner) such as location information m1 (x) as shown in fig. 4 based on the basic principle of UWB ranging ₁ ,y ₁ ,z ₁ )、m2(x ₂ ,y ₂ ,z ₂ ). The position information m1 and the position information m2 are two position coordinate points with opposite vector directions, and the vector direction of the position information m1 and the vector direction of the position information m2 are parallel to the z coordinate direction, that is, the two position information are respectively located at mirror positions on two sides of the intelligent dressing mirror. Meanwhile, the position direction of the second intelligent device relative to the intelligent dressing mirror can be determined through the two UWB antennas arranged at the position point D, and if the position direction of the second intelligent device relative to the intelligent dressing mirror is the direction opposite to the mirror surface of the intelligent dressing mirror, the position information m1 matched with the position direction (the direction opposite to the mirror surface of the intelligent dressing mirror) can be determined from the two position information m1 and m2, and the position information m1 is determined as the position information of the second intelligent device.

When determining at least one piece of position information of the second intelligent device, the first intelligent device can determine m pieces of distance information between the second intelligent device and m position points through a set ranging algorithm, and can construct spherical equations corresponding to the m position points according to a spherical three-dimensional coordinate formula based on the m pieces of distance information and respective position coordinates of the m position points. Wherein the position coordinates of each position point are also obtained by measurement. And then solving spherical equations corresponding to the m position points respectively, so that at least one position information of the second intelligent device can be accurately determined.

For example, taking the first intelligent device as an intelligent dressing mirror, for example, disposing one UWB antenna at each of the A, B, C three position points of the intelligent dressing mirror, taking the lower left corner of the intelligent dressing mirror as the origin of three-dimensional coordinates, setting the coordinates of the mirror surface perpendicular to the intelligent dressing mirror as the z-coordinate, taking the left and right of the mirror surface of the intelligent dressing mirror as the x-coordinate, and taking the vertical direction of the mirror surface of the intelligent dressing mirror as the y-coordinate, so that the coordinates of the position point a can be obtained by measurement as (x _A ,y _A 0), the coordinates of the position point B are (x) _B ,y _B 0), the coordinates of the position point C are (x _C ,y _C ,0). For example, as shown in fig. 5, in a schematic diagram of a three-dimensional space region where an intelligent dressing mirror provided in an embodiment of the present application is located, when a second intelligent device (such as a smart phone supporting UWB functions) is located at a certain position in the three-dimensional space region, when the intelligent dressing mirror detects a UWB signal emitted by the smart phone through a UWB antenna, distance information of three A, B, C position points of the smart phone and the intelligent dressing mirror, that is, r, can be determined through a ranging algorithm such as TOF or TW-TOF _A 、r _B And r _C . Then, according to the spherical three-dimensional coordinate formula (x-a) ² +(y-b) ² +(z-c) ² ＝r ² A spherical equation corresponding to each of the three A, B, C position points, namely, (x-x) _A ) ² +(y-y _A ) ² +(z-0) ² ＝r _A ² 、(x-x _B ) ² +(y-y _B ) ² +(z-0) ² ＝r _B ² And (x-x) _C ) ² +(y-y _C ) ² +(z-0) ² ＝r _C ² . Then, the three spherical equations are solved in a joint manner, so that at least one coordinate position of the smart phone can be solved, and the smart phone is assumed to be represented by M, such as M1 (x _M1 ,y _M1 ,z _M1 ) And M2 (x) _M2 ,y _M2 ,z _M2 ). The coordinate position M1 and the coordinate position M2 are two position coordinate points with opposite vector directions, namely, mirror positions of the two coordinate positions on two sides of the intelligent dressing mirror respectively.

It should be noted that, the positions of the two UWB antennas of the above position point D are variable, only the straight line formed by connecting the two UWB antennas needs to be guaranteed to be parallel to the z coordinate direction, and the three position points A, B, C are also variable, only a certain distance between the three position points needs to be guaranteed, and the calculation of the position of the coordinate point with a larger distance is more accurate, so that the coordinate position of the second intelligent device can be accurately measured. Of course, it is also possible to calculate by adding other position points than the m position points to compose a plurality of equation sets And each piece of position information in the at least one piece of position information of the second intelligent device is averaged to determine the at least one piece of position information of the second intelligent device, so that the measured at least one piece of position information of the second intelligent device can be more accurate. For example, taking the second smart device as a smart phone as an example, measuring a plurality of coordinate positions M1 and a plurality of coordinate positions M2 of the smart phone based on a plurality of equation sets, and then performing average calculation on the plurality of coordinate positions M1 to determine an average coordinate position M ₁ ' simultaneously, the average calculation is carried out on a plurality of coordinate positions M2, and an average coordinate position M is determined ₂ '. Finally, the coordinate position M ₁ ' and coordinate position M ₂ ' as two location information for a smart phone.

When the position direction of the second intelligent device relative to the first intelligent device is determined, the first intelligent device can determine the incident angle of the second intelligent device relative to the two UWB antennas through a set positioning algorithm, namely, the incident angle of the second intelligent device relative to the two UWB antennas can be timely and accurately determined through the phase difference of UWB signals emitted by the UWB antennas of the second intelligent device, and based on the incident angle, the position direction of the second intelligent device relative to the first intelligent device can be accurately determined, so that support is provided for accurately determining the position information of the second intelligent device.

For example, the first smart device is taken as an example of a smart dressing mirror, for example, two UWB antennas are deployed at a position point D of the smart dressing mirror, a straight line formed by connecting the two UWB antennas is parallel to the z coordinate direction, and a distance between the two UWB antennas is not greater than half a wavelength of the UWB signal, and the second smart device is taken as an example of a smart phone located at a certain position in the three-dimensional space region. The incident angles of the smart phone relative to the two UWB antennas can be measured through an AOA positioning algorithm and the like, and the position direction of the smart phone relative to the smart dressing mirror can be accurately determined according to the incident angles, for example, the smart phone is positioned in the right direction of the smart dressing mirror.

The AOA positioning algorithm is to measure an incident angle through a phase difference of UWB signals sent by UWB signal sending sources (such as smart phones) received by two antennas. For example, as shown in fig. 6, a schematic diagram of a phase angle of a transmission signal is provided in an embodiment of the present application. The UWB signals sent by the same signal transmitting source are received through the UWB antenna 1 and the UWB antenna 2, and the UWB signals received by the UWB antenna 1 and the UWB antenna 2 are asynchronous, so that the phase difference of the signals reaching the UWB antenna 1 and the UWB antenna 2 can be determined through mathematical operation, and the incident angle alpha of the signal transmitting source relative to the UWB antenna 1 and the UWB antenna 2 can be calculated by combining the distance between the UWB antenna 1 and the UWB antenna 2. Then, according to the incident angle alpha, the position direction of the signal emitting source relative to the UWB antenna 1 and the UWB antenna 2 can be determined. Wherein, the distance between UWB antenna 1 and UWB antenna 2 is less than or equal to half wavelength of UWB signal.

In addition, the three-dimensional space region where the first smart device is located may be determined by: the first intelligent device determines the position information of a plurality of mobile position points of the third intelligent device in the space range of the first intelligent device through a set position measurement algorithm; the third smart device is a UWB enabled mobile device. And then, based on the position information of the plurality of mobile position points, a three-dimensional space region where the first intelligent device is located can be constructed.

By way of example, continuing taking the three-dimensional space region where the intelligent dressing mirror shown in fig. 5 is located as an example, and assuming that the first intelligent device is the intelligent dressing mirror, and the third intelligent device is a smart phone with UWB function, when the three-dimensional space region where the intelligent dressing mirror is located is constructed, the smart phone can be respectively placed in eight corners of the three-dimensional space region, and for each corner, the intelligent dressing mirror determines the position information of the smart phone in the corner through a set position measurement algorithm, so that the position information of the smart phone in the eight corners can be measured, and the three-dimensional space region where the intelligent dressing mirror is located can be constructed according to the position information of the smart phone in the eight corners. Or, the smart phone may be placed at four corners of the three-dimensional space region with symmetrical oblique angles, or may be placed at four different spatial position points of the three-dimensional space region, which are not in the same plane, so that a three-dimensional space region where the smart dressing mirror is located may be constructed, which is not limited in this embodiment of the present application.

If the first smart device is a mobile terminal that is mobile, the trusted location range is a range that is no greater than a distance threshold from the mobile terminal. The mobile terminal can comprise a mobile terminal such as a smart phone, a smart bracelet or a tablet personal computer; the distance threshold is used to determine whether to allow the second smart device to connect to the wireless network in which the first smart device is located. Thus, authentication for a certain intelligent device can be completed through the distance threshold, and when the distance between the second intelligent device and the mobile terminal is not greater than the distance threshold, the second intelligent device can be considered as a trusted device, and the second intelligent device is allowed to be connected with a wireless network where the first intelligent device is located. And if the distance between the second intelligent device and the mobile terminal is determined to be greater than the distance threshold, the second intelligent device is considered to be an untrusted device, and the second intelligent device is not allowed to be connected with the wireless network where the first intelligent device is located. When the first intelligent device is a movable mobile terminal, the movable mobile terminal is close to a second intelligent device with a built-in UWB function by utilizing the safety and accuracy characteristics of UWB measurement distance, the distance information between the movable mobile terminal and the second intelligent device can be accurately determined according to the basic principle of UWB ranging, and then the movable mobile terminal determines whether the distance information between the movable mobile terminal and the second intelligent device is positioned in a trusted position range or not, namely, the movable mobile terminal judges whether the distance between the movable mobile terminal and the second intelligent device is smaller than or equal to a distance threshold. If the distance between the movable mobile terminal and the second intelligent device is smaller than or equal to the distance threshold, the movable mobile terminal confirms that the second intelligent device is a trusted device and sends the wireless account number and the wireless password to the second intelligent device, so that the second intelligent device can be connected with a wireless network where the first intelligent device is located in time. If the distance between the movable mobile terminal and the second intelligent device is greater than the distance threshold, the movable mobile terminal confirms that the second intelligent device is not a trusted device, and the wireless account number and the wireless password are not sent to the second intelligent device. The distance threshold may be set according to an experience value of a person skilled in the art, or according to an experimental result obtained by multiple experiments, or according to an actual application scenario, which is not limited in the embodiment of the present application.

The mobile terminal is taken as a smart phone, the second smart device is taken as a smart phone as an example for description, the smart phone is close to the smart television under the assumption that the distance threshold is 20cm, the smart phone measures the distance between the smart phone and the smart television through a ranging algorithm such as TOF or TW-TOF, for example, the measured distance between the smart phone and the smart television is 15cm, and therefore, the distance between the smart phone and the smart television can be determined to be smaller than the distance threshold, the smart television can be confirmed to be a trusted device, and a WIreless Fidelity (WiFi) network name and a WIreless WiFi password can be sent to the smart television, so that the smart television can be timely connected with a WIreless WiFi network where the smart phone is located. Or, for example, the measured distance between the smart phone and the smart television is 25cm, so that the distance between the smart phone and the smart television can be determined to be larger than the distance threshold, and therefore the smart television can be confirmed to be an untrustworthy device, and the wireless WiFi name and the wireless WiFi password cannot be sent to the smart television.

In step 202, the first smart device determines whether the location information of the second smart device is within a trusted location range.

In this embodiment of the present application, if the first smart device is a smart home device located at a fixed position, the trusted location range is a three-dimensional space area where the first smart device is located. Therefore, after the intelligent home equipment at the fixed position measures the position information of the second intelligent equipment through the set position measurement algorithm, whether the position information of the second intelligent equipment is positioned in a trusted position range or not can be determined, namely whether the position information of the second intelligent equipment is positioned in a three-dimensional space area where the first intelligent equipment is positioned or not is judged. For example, continuing to take the first intelligent device as an intelligent dressing mirror for an example, assuming that the second intelligent device is an intelligent air conditioner, when the intelligent dressing mirror detects a UWB signal emitted by the intelligent air conditioner through a UWB antenna, distance information of three position points A, B, C of the intelligent air conditioner and the intelligent dressing mirror can be determined through ranging algorithms such as TOF or TW-TOF, and at least one position information of the intelligent air conditioner is determined according to a spherical three-dimensional coordinate formula. And determining the position direction of the intelligent air conditioner relative to the intelligent dressing mirror through two UWB antennas of the position point D of the intelligent dressing mirror. Then, location information matching the location direction may be determined from at least one location information of the intelligent air conditioner. And finally, judging whether the position information of the intelligent air conditioner is positioned in the three-dimensional space area where the intelligent dressing mirror is positioned. Or, if a user needs to connect to a home wireless network when visiting a home where the smart dressing mirror is located, the smart dressing mirror can measure the position information of the smart phone with UWB function carried by the user through a set position measurement algorithm, and confirm that the smart phone of the user is a trusted device when determining that the position information of the smart phone is located in a three-dimensional space area where the smart dressing mirror is located, and send a wireless WiFi name and a wireless WiFi password of the home wireless network to the smart phone, so that the smart phone is connected to the home wireless network where the smart dressing mirror is located. Then, after the user leaves the home where the intelligent dressing mirror is located, the control authority of the user on the intelligent home equipment in the home where the intelligent dressing mirror is located is cancelled immediately.

If the first smart device is a mobile terminal that is mobile, the trusted location range is a range that is no greater than a distance threshold from the mobile terminal. Therefore, after the movable mobile terminal measures the position information of the second intelligent device through the set position measurement algorithm, whether the position information of the second intelligent device is located in a trusted position range or not can be determined, namely whether the distance between the second intelligent device and the movable mobile terminal is smaller than or equal to a distance threshold value is judged. In the exemplary embodiment, the mobile terminal is taken as an example of a smart phone, and the second smart device is assumed to be a smart refrigerator, and when the smart phone detects a UWB signal transmitted by the smart refrigerator through a UWB antenna, a distance between the smart refrigerator and the smart phone can be determined through a ranging algorithm such as a TOF or TW-TOF. And then judging whether the distance between the intelligent refrigerator and the intelligent mobile phone is smaller than or equal to a distance threshold value.

It should be noted that, the technical scheme in this application can also realize carrying out the accurate positioning to the little smart machine (such as intelligent bracelet, intelligent remote controller, smart mobile phone etc.) of built-in UWB function in the family, namely, can measure the three-dimensional coordinate position of these little smart machine accurately, for example, when the user forgets little smart machine such as smart mobile phone or intelligent remote controller and puts where, the user can inquire out the concrete position that a certain little smart machine is located through intelligent dressing mirror etc. first smart machine. Or, the intelligent mobile phone carried by the user can also be used for realizing accurate tracking of the position of the human body, and the intelligent lamp, the intelligent air conditioner, the air outlet degree, the intelligent television, the intelligent sound box and the like in the household can be controlled individually through the accurate tracking of the position of the human body.

And 203, if the first intelligent device determines that the position information of the second intelligent device is located in the trusted position range, transmitting a wireless account number and a wireless password to the second intelligent device.

In this embodiment of the present application, if the first smart device is a smart home device located at a fixed position, the trusted location range is a three-dimensional space area where the first smart device is located. If the intelligent home equipment at the fixed position determines that the position information of the second intelligent equipment is located in the three-dimensional space area where the first intelligent equipment is located, the second intelligent equipment is confirmed to be trusted equipment, and the wireless account number and the wireless password are sent to the second intelligent equipment, so that the second intelligent equipment can be timely connected with a wireless network where the intelligent home equipment at the fixed position is located, meanwhile, the intelligent home equipment at the fixed position can also send a message that the position information of the second intelligent equipment is located in the three-dimensional space area where the first intelligent equipment is located to the intelligent home control system, so that the intelligent home control system can timely add the control right of the second intelligent equipment into the intelligent home control system, and therefore management control of the second intelligent equipment by the intelligent home control system can be achieved, and support can be provided for users to intelligently control the second intelligent equipment. If the intelligent home equipment at the fixed position determines that the position information of the second intelligent equipment is not located in the three-dimensional space area where the first intelligent equipment is located, the second intelligent equipment is confirmed to be an untrusted equipment, and the wireless account number and the wireless password are not sent to the second intelligent equipment.

Illustratively, the description will be continued taking the first intelligent device as an example of the intelligent dressing mirror, assuming that the second intelligent device is an intelligent air conditioner. If the intelligent dressing mirror judges that the position information of the intelligent air conditioner is located in the three-dimensional space area where the intelligent dressing mirror is located, the intelligent air conditioner can be confirmed to be trusted equipment, and the wireless WiFi name and the wireless WiFi password are sent to the intelligent air conditioner, so that the intelligent air conditioner can be timely connected with the wireless WiFi network where the intelligent dressing mirror is located, and meanwhile, the intelligent dressing mirror can send the information of the trusted equipment of the intelligent air conditioner to the intelligent home control system, so that the intelligent home control system can timely add the control right of the intelligent air conditioner to the intelligent home control system. If the intelligent dressing mirror judges that the position information of the intelligent air conditioner is not located in the three-dimensional space area where the intelligent dressing mirror is located, the intelligent air conditioner can be confirmed to be an untrusted device, and the wireless WiFi name and the wireless WiFi password are not sent to the intelligent air conditioner.

If the first smart device is a mobile terminal that is mobile, the trusted location range is a range that is no greater than a distance threshold from the mobile terminal. If the movable mobile terminal determines that the distance between the second intelligent device and the movable mobile terminal is smaller than or equal to the distance threshold, the second intelligent device is confirmed to be a trusted device, and the wireless account number and the wireless password are sent to the second intelligent device, so that the second intelligent device can be timely connected with a wireless network where the intelligent home device located at the fixed position is located, meanwhile, the movable mobile terminal can also send a message that the distance between the second intelligent device and the movable mobile terminal is smaller than or equal to the distance threshold to the intelligent home control system, so that the intelligent home control system can timely add the control right of the second intelligent device into the intelligent home control system, management control of the second intelligent device by the intelligent home control system can be achieved, and support can be provided for a user to intelligently control the second intelligent device. If the movable mobile terminal determines that the distance between the second intelligent device and the movable mobile terminal is greater than the distance threshold, the second intelligent device is confirmed to be an untrusted device, and the wireless account number and the wireless password are not sent to the second intelligent device.

Illustratively, the description will be continued taking the mobile terminal as an example of a smart phone, assuming that the second smart device is a smart refrigerator. If the smart phone judges that the distance between the smart refrigerator and the smart phone is smaller than or equal to the distance threshold, the smart refrigerator is confirmed to be a trusted device, the wireless WiFi name and the wireless WiFi password are sent to the smart refrigerator, so that the smart refrigerator can be timely connected with a wireless WiFi network where the smart dressing mirror is located, and meanwhile, the smart phone can send a message of the trusted device of the smart refrigerator to the smart home control system, so that the smart home control system can timely add the control right of the smart refrigerator to the smart home control system. If the smart phone judges that the distance between the smart refrigerator and the smart phone is greater than the distance threshold, the smart refrigerator is confirmed to be an untrustworthy device, and the wireless WiFi name and the wireless WiFi password are not sent to the smart refrigerator.

The above embodiment shows that, because the authentication of the smart home device is completed by means of manual operation in the prior art, the authentication process of the smart home device needs to consume a long time, the control of the smart home device is not fast and convenient, and because the prior art may have the condition that a user outside the home where the smart device is located can control the smart device through the wireless network of the home connected by the mobile terminal, the control of the smart device has a security risk. Based on the method, the technical scheme of the invention provides more convenient service for indoor space object positioning in the intelligent home scene by introducing the ultra wideband communication UWB technology, thereby providing support for improving the control convenience and safety of the intelligent equipment.
