Next, a control method of the smart home device provided by the embodiment of the present application is explained in detail.
Fig. 2 is a flowchart of a control method of an intelligent home device provided in an embodiment of the present application, please refer to fig. 2, and the method includes the following steps.
Step 201: the method comprises the steps that the distance between the mobile terminal and a plurality of first intelligent home devices in a house and the device identification of the plurality of first intelligent home devices are determined through a UWB technology, and the distance between the mobile terminal and the plurality of first intelligent home devices and the device identification of the plurality of first intelligent home devices are sent to an intelligent home platform.
When the mobile terminal detects the pointing operation of the user, the duration of the pointing operation of the user is determined. Under the condition that the duration of the pointing operation of the user is longer than a duration threshold, the mobile terminal determines the distances between the mobile terminal and a plurality of first intelligent home devices in the house and the device identifiers of the plurality of first intelligent home devices respectively through the UWB technology, and sends the distances between the mobile terminal and the plurality of first intelligent home devices and the device identifiers of the plurality of first intelligent home devices to the intelligent home platform.
The pointing operation of the user can be triggered by pointing the mobile terminal to any intelligent home device in the house, or can also be triggered by swinging the mobile terminal and pointing the mobile terminal to any intelligent home device in the house. Wherein the time duration threshold is set in advance. Moreover, the duration threshold may also be adjusted according to different requirements.
In some embodiments, the mobile terminal transmits UWB ranging signals to the plurality of first smart home devices. After each first intelligent home device receives the UWB ranging signals sent by the mobile terminal, UWB response signals are sent to the mobile terminal, and the UWB response signals carry the device identifiers of the corresponding first intelligent home devices. The mobile terminal receives UWB response signals sent by the plurality of first intelligent home devices, and determines the distance between the mobile terminal and the plurality of first intelligent home devices respectively based on the sending time of UWB ranging signals and the receiving time of UWB response signals from the plurality of first intelligent home devices.
Because the plurality of first intelligent home devices are all internally provided with UWB components, the UWB components are used for receiving and transmitting UWB signals, after each first intelligent home device receives UWB ranging signals transmitted by the mobile terminal, UWB response signals can be transmitted to the mobile terminal through the built-in UWB components, and the UWB response signals carry device identifiers of the corresponding first intelligent home devices.
Because the distance between the mobile terminal and each first smart home device is determined in the same manner, the manner of determining the distance between the mobile terminal and one of the first smart home devices is described below by taking one of the first smart home devices as an example. For convenience of description, the first smart home device will be referred to as a first smart home device a.
The mobile terminal determines a time difference between the sending time of the UWB ranging signal and the receiving time of the UWB response signal based on the sending time of the UWB ranging signal and the receiving time of the UWB response signal from the first intelligent home device A, and further determines a distance between the mobile terminal and the first intelligent home device A based on the time difference.
As an example, the mobile terminal may determine the distance between the mobile terminal and the first smart home device a according to the following formula (1).
In the above formula (1), R represents a distance between the mobile terminal and the first smart home device a, c represents a propagation speed of the UWB signal, and T represents a time difference between a transmission time of the UWB ranging signal and a reception time of the UWB response signal from the first smart home device a. In general, since UWB signals are electromagnetic wave signals and the propagation speed of electromagnetic wave signals is equal to the speed of light, c is fixed.
The device identifier is used for uniquely identifying the smart home device, and the device identifier can be the number, manufacturer, brand, model and the like of the smart home device or can be obtained by combining the information.
Step 202: the intelligent home platform receives distances between the mobile terminal and a plurality of first intelligent home devices in a house respectively and device identifiers of the plurality of first intelligent home devices, and determines position coordinates of the mobile terminal based on the distances between the mobile terminal and the plurality of first intelligent home devices respectively and the device identifiers of the plurality of first intelligent home devices.
After receiving distances between the mobile terminal and a plurality of first intelligent home devices in the house and device identifiers of the plurality of first intelligent home devices, which are sent by the mobile terminal, the intelligent home platform acquires position coordinates of the plurality of first intelligent home devices based on the device identifiers of the plurality of first intelligent home devices. And then, determining the position coordinates of the mobile terminal based on the distances between the mobile terminal and the plurality of first intelligent home devices and the position coordinates of the plurality of first intelligent home devices.
The intelligent home platform stores the corresponding relation between the device identification and the position coordinates of the intelligent home device. Therefore, after receiving the device identifiers of the plurality of first intelligent home devices, the intelligent home platform acquires the position coordinates of the plurality of first intelligent home devices from the corresponding relation between the stored device identifiers and the position coordinates based on the device identifiers of the plurality of first intelligent home devices.
In some embodiments, the smart home platform determines a plurality of candidate position coordinates of the mobile terminal based on distances between the mobile terminal and the plurality of first smart home devices and the position coordinates of the plurality of first smart home devices, further determines a sum of squares of residuals corresponding to each candidate position coordinate based on distances between the mobile terminal and the plurality of first smart home devices and the plurality of candidate position coordinates, and then determines a candidate position coordinate with the smallest sum of squares of residuals corresponding to the plurality of candidate position coordinates as the position coordinate of the mobile terminal.
As an example, the smart home platform may determine candidate location coordinates of the mobile terminal according to the following formula (2).
m＝(A T A) -1 A T b(2)
Wherein in the above formula (2), m represents any one of the plurality of candidate position coordinates,
it should be noted that x represents the abscissa of any candidate position coordinate, y represents the ordinate of any candidate position coordinate, and x 1 Abscissa, y representing position coordinates of a first smart home device 1 Ordinate, d representing the position coordinates of the first smart home device 1 ' represents a distance between the mobile terminal and the first smart home device, and N represents a number of the plurality of first smart home devices.
That is, the smart home platform may input distances between the mobile terminal and the plurality of first smart home devices and the position coordinates of the plurality of first smart home devices into the above formula (2) respectively, so as to obtain a candidate position coordinate of the mobile terminal. The smart home platform can randomly combine the distances between the mobile terminal and the plurality of first smart home devices and the position coordinates of the plurality of first smart home devices, so as to input the distance into the formula (2). That is, the smart home platform may select some first smart home devices from the plurality of first smart home devices, input distances between the mobile terminal and the selected first smart home devices, respectively, and position coordinates of the selected first smart home devices into the above formula (2). At this time, the matrix a and the matrix b in the above formula (2) only include the elements corresponding to the selected first smart home device, and do not include the elements corresponding to the unselected first smart home devices in the plurality of first smart home devices, so as to obtain a candidate position coordinate of the mobile terminal. When the intelligent home platform selects different first intelligent home devices, different candidate position coordinates of the mobile terminal can be obtained, so that a plurality of candidate position coordinates of the mobile terminal are obtained.
In some embodiments, based on the distances between the mobile terminal and the plurality of first smart home devices and the position coordinates of the plurality of first smart home devices, respectively, a system of equations 1 may be created, where the system of equations 1 includes a plurality of equations that are in one-to-one correspondence with the plurality of first smart home devices. Subtracting the i-th equation and the i+1-th equation included in the equation set 1 yields an equation set 2 shown below. Then, the equation set 2 is converted into a matrix form, the obtained matrix 1 is am=b, the matrix 1 is solved by using a least square method, and the expression of a plurality of candidate position coordinates of the mobile terminal is m= (A) T A) - 1 A T b。
Because the distance between the mobile terminal and each first intelligent home device may have an error, the matrix 1 can be solved by adopting a least square method, so that the influence caused by the error is reduced, and the accuracy of the determined position coordinates of the mobile terminal is improved.
According to the method, a plurality of candidate position coordinates of the mobile terminal can be determined, and in order to ensure that the position coordinates of the mobile terminal are accurately determined, the intelligent home platform determines the residual square sum corresponding to each candidate position coordinate. Since the sum of squares of residuals is used to characterize the degree of fitting between the candidate location coordinates of the mobile terminal and the location coordinates of the mobile terminal, i.e. if the sum of squares of residuals corresponding to a certain candidate location coordinate is smaller, it is indicated that the candidate location coordinate is closer to the location coordinate of the mobile terminal. Therefore, the candidate position coordinates having the smallest sum of squares of residuals corresponding to the plurality of candidate position coordinates are determined as the position coordinates of the mobile terminal.
As one example, the smart home platform may determine the sum of squares of residuals according to equation (3) below.
Wherein in the above formula (3), f represents the sum of squares of residuals corresponding to any one of the plurality of candidate position coordinates, d i ' represents a distance, d, between the mobile terminal and an ith first smart home device of the plurality of first smart home devices i Representing the distance between any candidate position coordinate and the position coordinate of the ith first intelligent home equipment, wherein x represents the abscissa of any candidate position coordinate, y represents the ordinate of any candidate position coordinate, and x is the coordinate of the first intelligent home equipment i Abscissa representing position coordinates of the ith first smart home device, y i And the ordinate representing the position coordinates of the ith first smart home device, and N representing the number of the plurality of first smart home devices.
The manner in which the smart home platform determines the location coordinates of the mobile terminal in the above manner is an example. In other embodiments, the smart home platform may also determine the location coordinates of the mobile terminal in other ways. The smart home platform obtains the position coordinates of the plurality of first smart home devices based on the device identifiers of the plurality of first smart home devices, and directly determines the position coordinates of the mobile terminal based on the distances between the mobile terminal and the plurality of first smart home devices and the position coordinates of the plurality of first smart home devices. That is, the smart home platform obtains the position coordinates of the plurality of first smart home devices from the correspondence between the stored device identifications and the position coordinates based on the device identifications of the plurality of first smart home devices. And then, drawing a plurality of circles corresponding to the first intelligent home devices one by taking the position coordinates of the first intelligent home devices as dots and the distance between the mobile terminal and the first intelligent home devices as a radius, and determining the position coordinates of the intersection points of the circles as the position coordinates of the mobile terminal.
For example, referring to fig. 3, fig. 3 is a schematic diagram of determining location coordinates of a mobile terminal according to an embodiment of the present application. In fig. 3, the distances between the mobile terminal and the refrigerator, the oven and the washing machine are 1 meter, 3 meters and 5 meters, respectively. At this time, the smart home platform uses the position coordinates (x 1 ,y 1 ) Circle 1 is drawn with a radius of 1 meter as a circle point, and the position coordinates (x 2 ,y 2 ) Is a round dot, a circle 2 is drawn with a radius of 3 meters, and the position coordinates (x 3 ,y 3 ) Circle 3 is drawn with a radius of 5 meters as a circle point. The position coordinates of the intersection point A of the circles 1, 2 and 3 are the position coordinates of the mobile terminal.
It should be noted that, the position coordinates of the plurality of first smart home devices and the position coordinates of the mobile terminal belong to the same coordinate system, and the coordinate system is established by taking a certain point of the house as an origin. In the following, the position coordinate range of each room in the house also belongs to the coordinate system.
Step 203: the intelligent home platform determines the position coordinates of a plurality of second intelligent home devices positioned in a target room based on the position coordinates of the mobile terminal, and sends the position coordinates of the mobile terminal and the position coordinates of the plurality of second intelligent home devices to the mobile terminal, wherein the target room is the room where the mobile terminal is currently positioned in the house.
In some embodiments, the smart home platform determines a room identification of a room in which the mobile terminal is currently located in the house based on the location coordinates of the mobile terminal, so as to obtain the room identification of the target room. Based on the room identification of the target room, the intelligent home platform acquires the equipment identifications of a plurality of second intelligent home equipment in the target room from the corresponding relation between the stored room identifications and the equipment identifications. Based on the above description, the smart home platform further stores a correspondence between device identifiers of the smart home devices and the position coordinates, and at this time, the smart home platform determines the position coordinates of the plurality of second smart home devices located in the target room from the correspondence between the stored device identifiers and the position coordinates based on the device identifiers of the plurality of second smart home devices. And then, the position coordinates of the mobile terminal and the position coordinates of the plurality of second intelligent home devices are sent to the mobile terminal.
The intelligent home platform stores the position coordinate ranges of all rooms in the house, so the intelligent home platform can compare the position coordinates of the mobile terminal with the position coordinate ranges of all rooms in the house, and the room identification of the target room can be determined. That is, if the position coordinates of the mobile terminal fall within the position coordinate range of a certain room, the room identification of the room is determined as the room identification of the target room.
The location coordinate range of each room in the house is determined in advance by the smart home platform based on the floor size of each room in the house and the floor shape of the room. That is, the smart home platform stores a spatial division map (also referred to as a house pattern) of the house, establishes a coordinate system with a point in the spatial division map of the house as an origin, and, when the floor shape of the room is square or rectangular, determines a first minimum distance and a first maximum distance from the origin of the coordinate system in the horizontal axis direction of the room based on the floor size of the room, determines the first minimum distance as a minimum abscissa of the position coordinate range of the room, and determines the first maximum distance as a maximum abscissa of the position coordinate range of the room for any room. Similarly, a second minimum distance and a second maximum distance of the room from the origin of the coordinate system in the longitudinal axis direction are determined, the second minimum distance is determined as the minimum ordinate of the position coordinate range of the room, and the second maximum distance is determined as the maximum ordinate of the position coordinate range of the room, so that the position coordinate range of the room is obtained.
For example, referring to fig. 4, fig. 4 is a schematic diagram of a spatial division diagram of a house according to an embodiment of the present application. In fig. 4, a coordinate system is established with the lower left corner of the main sleeper in the spatial division diagram of the house as the origin. Taking the main couch as an example, the first minimum distance of the main couch from the origin of the coordinate system in the horizontal axis direction is 0 and the first maximum distance is 3400mm. Therefore, the minimum abscissa of the position coordinate range of the main lying is 0, and the maximum abscissa is 3400. Similarly, a second minimum distance of 0 and a second maximum distance of 4000mm from the origin of the coordinate system in the direction of the longitudinal axis of the main sleeper is determined. Therefore, the minimum ordinate of the position coordinate range of the main lying is 0, and the maximum ordinate is 4000.
The above description is given taking the floor shape of the room as square and rectangle as an example. Of course, the floor shape of the room may be another shape, and in this case, there may be a plurality of coordinate ranges on the horizontal axis and a plurality of coordinate ranges on the vertical axis, and the floor shape of the room may be specifically determined.
In addition, the above determination of the position coordinate range of each room by the spatial division map of the house is an example. In other embodiments, the user may also determine and report the information to the smart home platform through the mobile terminal. That is, the user may input the position coordinate range of each room in the mobile terminal and transmit the position coordinate range of each room to the smart home platform.
After the intelligent home platform determines the position coordinates of the plurality of second intelligent home devices in the target room, the position coordinates of the mobile terminal and the position coordinates of the plurality of second intelligent home devices are sent to the mobile terminal, and the position coordinates of the intelligent home devices in other rooms do not need to be sent to the mobile terminal. That is, the smart home platform may shield the mobile terminal from controlling other smart home devices in the non-target room. Therefore, the mobile terminal can be prevented from performing error control on other intelligent household equipment in a non-target room, and the control precision of the mobile terminal on the target intelligent household equipment is further improved.
After the intelligent home equipment is configured in the house, the position of the intelligent home equipment is basically unchanged, so that the corresponding relation between the equipment identification and the position coordinate of the intelligent home equipment can be stored. The corresponding relation between the equipment identifier and the position coordinates and the corresponding relation between the room identifier and the equipment identifier are determined in advance for the intelligent home platform. For example, the correspondence between the device identifier and the location coordinate, and the correspondence between the room identifier and the device identifier may be determined by the smart home platform in the process of binding the smart home device, where the binding process of the smart home device will be described below, and will not be described herein.
The room identifier is used to uniquely identify the room, and may be the number, name, floor space, type, etc. of the room, or may be obtained by a combination of these pieces of information.
For example, please refer to fig. 5, fig. 5 is a schematic diagram for determining a room identifier according to an embodiment of the present application. In fig. 5, a user selects an existing house or a newly-built house through a mobile terminal to determine a spatial division map of the house. If the user determines a spatial division map of the house through the mobile terminal, a room identification may be assigned to each room within the house based on the spatial division map of the house. If the user does not select an existing house or newly build a house through the mobile terminal, that is, the user does not determine a space division diagram of the house through the mobile terminal, room identifications of a plurality of rooms in the house can be customized. That is, the user may enter a room identification for each room within the house in the mobile terminal.
Step 204: the mobile terminal receives the position coordinates of the mobile terminal and the position coordinates of a plurality of second intelligent home devices in a target room, which are sent by the intelligent home platform, and controls the target intelligent home devices in the plurality of second intelligent home devices based on the position coordinates of the mobile terminal and the position coordinates of the plurality of second intelligent home devices.
The mobile terminal determines the deviation angles between the mobile terminal and the plurality of second intelligent home devices based on the position coordinates of the mobile terminal and the position coordinates of the plurality of second intelligent home devices, and further determines the target intelligent home device from the plurality of second intelligent home devices based on the deviation angles between the mobile terminal and the plurality of second intelligent home devices. Then, the target smart home device is controlled.
Because the plurality of second intelligent home devices may be located at different heights, in order to uniformly compare the deviation angles between the mobile terminal and the plurality of second intelligent home devices, the deviation angle between the mobile terminal and the second intelligent home devices is determined by taking the horizontal plane where the mobile terminal is located as a reference plane. That is, the offset angle between the mobile terminal and the second smart home device is an angle between a line connecting a center point of the mobile terminal and a center point of the second smart home device and a reference plane (horizontal plane).
The method for determining the deviation angle between the mobile terminal and each second smart home device is the same, so that the method for determining the deviation angle between the mobile terminal and one of the second smart home devices is described below by taking one of the second smart home devices as an example. For convenience of description, the second smart home device will be referred to as a second smart home device B.
As an example, the mobile terminal may determine the deviation angle between the mobile terminal and the second smart home device B according to the following formula (4).
In the above formula (4), θ represents a deviation angle between the mobile terminal and the second smart home device B, and y p Representing the position of a second smart home device BOrdinate of the coordinates, y represents ordinate of the position coordinates of the mobile terminal, x p And x represents the abscissa of the position coordinate of the mobile terminal.
In some embodiments, the mobile terminal determines, based on the deviation angles between the mobile terminal and the plurality of second smart home devices, the implementation procedure of the target smart home device from the plurality of second smart home devices, including: and under the condition that at least one second intelligent home device with the deviation angle smaller than the angle threshold value exists between the plurality of second intelligent home devices and the mobile terminal, selecting the second intelligent home device with the smallest deviation angle between the plurality of second intelligent home devices and the mobile terminal from the at least one second intelligent home device, if the number of the selected second intelligent home devices is 1, determining the selected second intelligent home device as the target intelligent home device, and if the number of the selected second intelligent home devices is greater than 1, determining the distance between each selected second intelligent home device and the mobile terminal based on the position coordinates of the mobile terminal and the position coordinates of each selected second intelligent home device, and determining the second intelligent home device with the smallest distance between the selected second intelligent home device and the mobile terminal as the target intelligent home device.
After determining the deviation angles between the mobile terminal and the plurality of second intelligent home devices, the mobile terminal judges whether at least one second intelligent home device with the deviation angle smaller than an angle threshold value exists in the plurality of second intelligent home devices. And if at least one second intelligent home device with the deviation angle smaller than the angle threshold value between the mobile terminal and the second intelligent home devices does not exist in the plurality of second intelligent home devices, indicating that the target intelligent home device does not exist in the plurality of second intelligent home devices, and ending the operation. And if at least one second intelligent home device with the deviation angle smaller than the angle threshold value with the mobile terminal exists in the plurality of second intelligent home devices, indicating that a target intelligent home device exists in the plurality of second intelligent home devices. At this time, the mobile terminal selects a second smart home device having the smallest deviation angle from the mobile terminal from the at least one second smart home device. And if only one second intelligent home equipment is selected, determining the selected second intelligent home equipment as the target intelligent home equipment. And if at least two second intelligent home devices are selected, determining the second intelligent home device with the smallest distance between the second intelligent home device and the mobile terminal as the target intelligent home device.
The angle threshold is the maximum angle at which the mobile terminal can control the intelligent household equipment, and if the deviation angle between the intelligent household equipment and the mobile terminal is smaller than the angle threshold, the position of the intelligent household equipment is indicated to be within the control range of the mobile terminal. At this time, the mobile terminal can control the smart home device, that is, the target smart home device exists. If the deviation angle between the intelligent home equipment and the mobile terminal is larger than the angle threshold, the position of the intelligent home equipment is not in the control range of the mobile terminal, and at the moment, the mobile terminal cannot control the intelligent home equipment, namely, the target intelligent home equipment does not exist.
The user triggers the mobile terminal to control the target intelligent home equipment by pointing the mobile terminal to the intelligent home equipment in the house, so that the target intelligent home equipment can be determined through the deviation angles between the mobile terminal and the second intelligent home equipment. And under the condition that the deviation angle between at least two second intelligent home devices and the mobile terminal is minimum, determining the second intelligent home device with the minimum distance between the at least two second intelligent home devices and the mobile terminal as the target intelligent home device in order to improve the control precision of the mobile terminal on the target intelligent home device. In this way, the target smart home device can be preferentially determined from the at least two second smart home devices.
Wherein the angle threshold is set in advance. Moreover, the angle threshold can be adjusted according to different requirements.
As an example, the mobile terminal may determine the distance between each selected second smart home device and the mobile terminal according to the following formula (5).
In the above formula (5), S represents a distance between the mobile terminal and any selected second smart home device, and x q And x represents the abscissa of the position coordinate of the mobile terminal, y q And representing the ordinate of the position coordinate of the second intelligent home equipment, and y represents the ordinate of the position coordinate of the mobile terminal.
It should be noted that, the above manner is that after the smart home platform determines the position coordinates of the mobile terminal and the position coordinates of the plurality of second smart home devices, the position coordinates are sent to the mobile terminal. And the mobile terminal determines target intelligent household equipment from the plurality of second intelligent household equipment based on the position coordinates of the mobile terminal and the position coordinates of the plurality of second intelligent household equipment. Of course, in other embodiments, after determining the position coordinates of the mobile terminal and the position coordinates of the plurality of second smart home devices, the smart home platform may determine the target smart home device from the plurality of second smart home devices directly based on the position coordinates of the mobile terminal and the position coordinates of the plurality of second smart home devices. And then, the device identification of the target intelligent home device is sent to the mobile terminal. Thus, after the mobile terminal receives the device identifier of the target intelligent home device sent by the intelligent home platform, the target intelligent home device can be controlled.
The process of determining the target smart home device from the plurality of second smart home devices based on the position coordinates of the mobile terminal and the position coordinates of the plurality of second smart home devices by the smart home platform is similar to the process of determining the target smart home device by the mobile terminal, so the relevant content of the above steps can be referred to, and will not be repeated here.
After the mobile terminal determines the target intelligent home equipment, the target intelligent home equipment can be controlled according to different modes based on the type of the target intelligent home equipment. That is, in the case that the type of the target smart home device is included in the first type set, the mobile terminal transmits a UWB control signal to the target smart home device to control the target smart home device. And controlling the target intelligent home equipment by the mobile terminal through the intelligent home platform under the condition that the type of the target intelligent home equipment is contained in the second type set. Thus, richer application scenes can be satisfied.
For example, the first type of collection includes televisions, hangers, and door locks. The second type of collection includes air conditioners, ovens, refrigerators and microwave ovens. When the target smart home device is a door lock, the mobile terminal transmits a UWB control signal to the door lock, wherein the UWB control signal is used for indicating to close the door lock, because the type of the door lock is contained in the first type set. After the door lock receives the UWB control signal, the door lock is closed. When the target smart home device is an oven, the mobile terminal sends the device identifier of the oven to the smart home platform through network devices such as a WIFI (Wireless Fidelity ) router and the like because the type of the oven is contained in the second type set. After receiving the equipment identification of the oven, the intelligent home platform acquires a menu, a cooking mode and an oven state of the oven from the stored corresponding relation between the equipment identification and the equipment information of the intelligent home equipment, and sends the menu, the cooking mode and the oven state to the mobile terminal through network equipment such as a WIFI router. After receiving a menu, a cooking mode and an oven state of an oven sent by the intelligent home platform, the mobile terminal generates a control instruction and sends the control instruction to the intelligent home platform. After receiving the control instruction, the intelligent home platform sends the control instruction to the oven through network equipment such as a WIFI router and the like.
For example, referring to fig. 6, fig. 6 is a schematic diagram of a control target smart home device according to an embodiment of the present application. In fig. 6, the target smart home device determined by the mobile terminal from the three second smart home devices, namely, the oven, the refrigerator and the microwave oven, is the oven. And the mobile terminal sends the equipment identification of the oven to the intelligent home platform through network equipment such as a WIFI router and the like. After receiving the equipment identification of the oven, the intelligent home platform acquires a menu, a cooking mode and an oven state of the oven from the stored corresponding relation between the equipment identification and the equipment information of the intelligent home equipment, and sends the menu, the cooking mode and the oven state to the mobile terminal through network equipment such as a WIFI router. After receiving a menu, a cooking mode and an oven state of an oven sent by the intelligent home platform, the mobile terminal generates a control instruction and sends the control instruction to the intelligent home platform. After receiving the control instruction, the intelligent home platform sends the control instruction to the oven through network equipment such as a WIFI router and the like.
The mobile terminal obtains the menu, the cooking mode and the oven state of the oven through the intelligent home platform as an example. The mobile terminal can also acquire the exclusive washing scheme of the washing machine based on the material, the type and the season of the clothes through the intelligent home platform. Or, the condition of food materials in the refrigerator is obtained through the intelligent home platform, so that a fresh-keeping scheme is set and the food materials are timely supplemented.
For example, please refer to fig. 7, fig. 7 is a schematic diagram of information acquisition through the smart home platform according to an embodiment of the present application. In fig. 7, the mobile terminal may acquire a recipe, a cooking mode, and an oven state of the oven through the smart home platform. The mobile terminal can also acquire the exclusive washing scheme of the washing machine through the intelligent home platform. Or, the condition of food materials in the refrigerator is obtained through the intelligent home platform, so that a fresh-keeping scheme is set and the food materials are timely supplemented.
The first type set is a set formed by types of intelligent household equipment controlled by the mobile terminal through the UWB signal, and the second type set is a set formed by types of intelligent household equipment controlled by the mobile terminal through the intelligent household platform. The first type set and the second type set are obtained from the intelligent home platform by the mobile terminal in advance and stored locally. That is, after the first type set and the second type set are determined, the intelligent home platform directly sends the first type set and the second type set to the mobile terminal for storage.
Under the condition that the duration of pointing to the target intelligent household equipment by the mobile terminal is longer than the duration threshold, the mobile terminal can send UWB control signals to the target intelligent household equipment or control the target intelligent household equipment through the intelligent household platform. Therefore, the mobile terminal can determine whether to continue to control the target intelligent home equipment, and the current operation is avoided due to the fact that the user touches the mobile terminal by mistake.
Based on the above description, the intelligent home platform stores the corresponding relation between the device identifier and the position coordinate, and the corresponding relation between the room identifier and the device identifier, where the corresponding relation may be stored by the intelligent home platform in the process of binding the intelligent home device. Accordingly, the binding process of the third smart home device will be described below taking the third smart home device as an example.
In some embodiments, after the third smart home device is added to the house, the mobile terminal further needs to send the device identifier, the location coordinate, and the room identifier of the room in which the third smart home device is located to the smart home platform. After receiving the device identifier and the position coordinate of the third intelligent home device and the room identifier of the room in the house, which are sent by the mobile terminal, the intelligent home platform can store the device identifier and the position coordinate of the third intelligent home device into a corresponding relationship between the device identifier and the position coordinate. And simultaneously, storing the equipment identifier of the third intelligent home equipment and the room identifier of the room in the house into the corresponding relation between the room identifier and the equipment identifier.
That is, the mobile terminal receives a UWB device binding signal sent by a third smart home device to be bound, where the UWB device binding signal carries a device identifier of the third smart home device, obtains a position coordinate of the third smart home device, and a room identifier of a room where the third smart home device is located in a house, and sends the device identifier, the position coordinate, and the room identifier of the room where the third smart home device is located in the house to the smart home platform, so as to instruct the smart home platform to store the device identifier, the position coordinate, and the room identifier of the room where the third smart home device is located in the house.
When the mobile terminal detects the adding operation of the intelligent household equipment of the user, the mobile terminal displays an adding interface, wherein the adding interface comprises two options of manual adding and automatic searching. Namely, the user can select to manually add the third smart home device to be bound, or can select to automatically search through the mobile terminal to add the third smart home device to be bound. If the user selects to manually add the third intelligent home equipment to be bound, the user inputs the name of the third intelligent home equipment to be bound in an input box, and when the mobile terminal detects the confirmation operation of the user, a UWB request binding signal is sent to the third intelligent home equipment to be bound. After receiving the UWB request binding signal sent by the mobile terminal, the third intelligent home device sends a UWB device binding signal to the mobile terminal through a built-in UWB component, and the UWB device binding signal carries the device identifier of the third intelligent home device. If the user selects to add the third smart home device to be bound through automatic searching of the mobile terminal, the mobile terminal receives a UWB device binding signal sent by the third smart home device to be bound, wherein the UWB device binding signal carries a device identifier of the third smart home device.
The mobile terminal obtains the position coordinates of the third intelligent home equipment, and the implementation process of the room identification of the room where the third intelligent home equipment is located in the house comprises the following steps: the mobile terminal displays a first user interface, wherein the first user interface comprises a space division diagram of a house, the position coordinates of the first position are determined in response to the selection operation of the first position in the space division diagram, the room identification of the room where the first position is located, the position coordinates of the first position are determined to be the position coordinates of the third intelligent home equipment, and the room identification of the room where the first position is located is determined to be the room identification of the room where the third intelligent home equipment is located in the house. That is, the mobile terminal displays a first user interface including a spatial division map of the house. The user can select the position of the third intelligent home equipment in the space division diagram, when the mobile terminal detects the selection operation of the user, the position selected by the user is determined to be the first position, then the position coordinate of the first position is determined, the room identifier of the room where the first position is located is determined, the position coordinate of the first position is determined to be the position coordinate of the third intelligent home equipment, and the room identifier of the room where the first position is located is determined to be the room identifier of the room where the third intelligent home equipment is located in the house.
The manner in which the mobile terminal obtains the position coordinates of the third smart home device and the room identifier of the room in which the third smart home device is located in the house in the above manner is an example. In other embodiments, the mobile terminal may further obtain the location coordinates of the third smart home device and the room identifier of the room in which the third smart home device is located in the house in other manners. When the mobile terminal detects the binding operation of the user, the mobile terminal displays a second user interface, wherein the second user interface comprises an input frame corresponding to the position coordinates of the third intelligent home equipment and room identifications of a plurality of rooms in the house. The user can input the position coordinate of the third smart home device in the input box, and can also select the room identifier of the room where the third smart home device is located from the plurality of room identifiers. When the mobile terminal detects the confirmation operation of the user, the position coordinate input by the user is determined to be the position coordinate of the third intelligent household equipment, and the room identification selected by the user is determined to be the room identification of the room where the third intelligent household equipment is located in the house.
The binding operation of the user can be triggered by means of voice interaction, and also can be triggered by clicking operation of a binding button. For example, the user triggers the binding operation by entering "bind smart home device" through voice. The user's confirmation operation may be triggered by means of a voice interaction, and may also be triggered by a click operation of a submit button in the second user interface.
For example, please refer to fig. 8, fig. 8 is a schematic diagram of a binding third smart home device according to an embodiment of the present application. In fig. 8, the mobile terminal displays a first user interface, and a user adds a third smart home device in a plurality of rooms included in the house.

That is, the mobile terminal may manage only one house, or may manage a plurality of houses at the same time. If the mobile terminal manages a plurality of houses simultaneously, when the mobile terminal detects a switching operation of the user, the mobile terminal displays a third user interface, the third user interface includes house identifications of the plurality of houses, and the user can select one house identification from the plurality of house identifications. When the mobile terminal detects the confirmation operation of the user, the house corresponding to the house identification selected by the user is determined to be the house which is required to be controlled by the intelligent household equipment currently. Then, the mobile terminal controls the smart home devices in the house according to the processes of the steps 201 to 204.
The house identifier is used for uniquely identifying the house, and the house identifier may be the number, the floor area, the type, etc. of the house, or may be obtained by combining these information.
Optionally, in some embodiments, the mobile terminal may also install an Application (APP). At this time, the mobile terminal may implement the processes of step 201 and step 204 through the smart home APP.
In the embodiment of the application, the UWB technology is used for transmitting data by utilizing extremely narrow pulses of nanosecond to microsecond levels, and the UWB signal has higher spatial resolution. Therefore, the mobile terminal can accurately determine the distances between the mobile terminal and the plurality of first intelligent home devices in the house respectively through the UWB technology. Then, the intelligent home platform can accurately determine the position coordinates of the mobile terminal and the room where the mobile terminal is currently located in the house based on the distances between the mobile terminal and the plurality of first intelligent home devices respectively. And the target intelligent home equipment determined by the mobile terminal is more accurate, so that the control precision of the mobile terminal on the target intelligent home equipment is improved. In addition, after the mobile terminal determines the target intelligent home equipment, the target intelligent home equipment can be controlled according to different modes based on the type of the target intelligent home equipment. Namely, the mobile terminal can directly control the target intelligent household equipment, and can also control the target intelligent household equipment through the intelligent household platform. Thus, richer application scenes can be satisfied.
