The following explains the control method of the smart home device in detail according to the embodiment of the present application.
Fig. 2 is a flowchart of a method for controlling smart home devices according to an embodiment of the present application, please refer to fig. 2, where the method includes the following steps.
Step 201: the mobile terminal determines distances between the mobile terminal and a plurality of first intelligent household devices in a house and device identifications of the first intelligent household devices through a UWB technology, and sends the distances between the mobile terminal and the first intelligent household devices and the device identifications of the first intelligent household devices to an intelligent household 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 greater than a duration threshold value, the mobile terminal determines the distances between the mobile terminal and the plurality of first intelligent household devices in the house and the device identifications of the plurality of first intelligent household devices through a UWB technology, and sends the distances between the mobile terminal and the plurality of first intelligent household devices and the device identifications of the plurality of first intelligent household devices to the intelligent household platform.
The pointing operation of the user can be triggered in a mode that the mobile terminal points to any intelligent household device in the house, or can be triggered in a mode that the mobile terminal is swung and points to any intelligent household device in the house. Wherein the duration threshold is set in advance. Moreover, the duration threshold value can 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 smart home device receives the UWB ranging signal sent by the mobile terminal, a UWB response signal is sent to the mobile terminal, and the UWB response signal carries the device identifier of the corresponding first smart home device. The mobile terminal receives UWB response signals sent by the first intelligent household devices, and determines distances between the mobile terminal and the first intelligent household devices respectively based on the sending time of the UWB ranging signals and the receiving time of the UWB response signals from the first intelligent household devices.
Because each of the plurality of first smart home devices is internally provided with a UWB component, and the UWB components are used for receiving and sending UWB signals, after each first smart home device receives a UWB ranging signal sent by the mobile terminal, a UWB response signal can be sent to the mobile terminal through the respective built-in UWB component, and the UWB response signal carries the device identifier of the corresponding first smart home device.
Since the determination methods of the distance between the mobile terminal and each of the first smart home devices are the same, the determination method of the distance between the mobile terminal and each of the first smart home devices will be described by taking one of the first smart home devices as an example. For convenience of description, the first smart home device is 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 from the first smart home device a based on the sending time of the UWB ranging signal and the receiving time of the UWB response signal from the first smart home device a, and further determines a distance between the mobile terminal and the first smart 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).
Figure BDA0003492426780000081
Wherein, 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, UWB signals are electromagnetic wave signals, and the propagation speed of electromagnetic wave signals is equal to the speed of light, so c is fixed.
The device identifier is used for uniquely identifying the smart home device, and may be a serial number, a manufacturer, a brand, a model number, and the like of the smart home device, or may be obtained by combining these pieces of 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 identifications of the first intelligent home devices, and determines position coordinates of the mobile terminal based on the distances between the mobile terminal and the first intelligent home devices and the device identifications of the first intelligent home devices.
After receiving the distances between the mobile terminal and the plurality of first intelligent home devices in the house and the device identifications of the plurality of first intelligent home devices, which are sent by the mobile terminal, the intelligent home platform acquires the position coordinates of the plurality of first intelligent home devices based on the device identifications of the plurality of first intelligent home devices. Then, the position coordinates of the mobile terminal are determined based on the distances between the mobile terminal and the plurality of first smart home devices respectively and the position coordinates of the plurality of first smart home devices.
The intelligent home platform stores the corresponding relation between the equipment identification and the position coordinate of the intelligent home equipment. Therefore, after receiving the device identifiers of the first smart home devices, the smart home platform acquires the position coordinates of the first smart home devices from the stored correspondence between the device identifiers and the position coordinates based on the device identifiers of the first smart 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, respectively, and the position coordinates of the plurality of first smart home devices, further determines a sum of squares of residuals corresponding to each of the candidate position coordinates based on the distances between the mobile terminal and the plurality of first smart home devices, respectively, 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 a plurality of candidate position coordinates of the mobile terminal according to the following formula (2).
m＝(ATA)-1ATb(2)
Wherein in the above formula (2), m represents any one of the candidate position coordinates,
Figure BDA0003492426780000091
it should be noted that x represents the abscissa of the position coordinate of the candidate, y represents the ordinate of the position coordinate of the candidate, and x1Abscissa, y, representing position coordinates of a first smart home device1Ordinate representing the position coordinate of the first smart home device, d1' represents a distance between the mobile terminal and the first smart home device, and N represents the number of the plurality of first smart home devices.
That is, the smart home platform may input 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 into the above formula (2), so as to obtain a candidate position coordinate of the mobile terminal. The distance between the mobile terminal and the plurality of first intelligent household devices and the position coordinates of the plurality of first intelligent household devices can be randomly combined by the intelligent household platform, so that the distance is input 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, and input the distance between the mobile terminal and the selected first smart home devices, and the 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 formula (2) only include elements corresponding to the selected first smart home devices, and do not include elements corresponding to 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, and therefore 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, an equation set 1 as shown below may be created, where the equation set 1 includes a plurality of equations in one-to-one correspondence with the plurality of first smart home devices. The i-th equation included in the equation set 1 is subtracted from the i + 1-th equation to obtain 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 a least square method, and the expression of the candidate position coordinates of the mobile terminal is obtained as m ═ a (a)TA)- 1ATb。
Figure BDA0003492426780000101
Figure BDA0003492426780000102
Because there may be an error in the distance between the mobile terminal and each first smart home device, the matrix 1 may be solved by using a least square method, so that the influence caused by the error is reduced, and the accuracy of the determined position coordinate 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 a residual square sum corresponding to each candidate position coordinate. Since the sum of squares of the residuals is used to characterize the degree of fit between the candidate position coordinates of the mobile terminal and the position coordinates of the mobile terminal, that is, if the sum of squares of the residuals corresponding to a certain candidate position coordinate is smaller, it indicates that the candidate position coordinate is closer to the position coordinates of the mobile terminal. Therefore, the candidate position coordinate with the smallest sum of squared residuals among the plurality of candidate position coordinates is determined as the position coordinate of the mobile terminal.
As an example, the smart home platform may determine the sum of the squares of the residuals according to equation (3) below.
Figure BDA0003492426780000103
Wherein, in the above formula (3), f represents the sum of squares of residuals corresponding to any one of the candidate position coordinates, and di' represents a distance between the mobile terminal and the ith intelligent household device in the plurality of first intelligent household devices, diRepresenting the distance between the position coordinate of any candidate position coordinate and the position coordinate of the ith first smart home device, x representing the abscissa of any candidate position coordinate, y representing the ordinate of any candidate position coordinate, and xiAn abscissa, y, representing the position coordinate of the ith first smart home deviceiAnd the vertical coordinate represents the position coordinate of the ith first intelligent household equipment, and N represents the number of the plurality of first intelligent household equipment.
The manner in which the smart home platform determines the position 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 manners. Exemplarily, the smart home platform acquires 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 location coordinates of the plurality of first smart home devices from the stored correspondence between the device identifiers and the location coordinates based on the device identifiers of the plurality of first smart home devices. Then, the position coordinates of each first smart home device are used as round points, the distance between the mobile terminal and each first smart home device is used as a radius, a plurality of circles corresponding to the plurality of first smart home devices one to one are drawn, and the position coordinates of the intersection points of the plurality of circles are determined as the position coordinates of the mobile terminal.
For example, please refer to fig. 3, fig. 3 is a schematic diagram illustrating a method for determining location coordinates of a mobile terminal according to an embodiment of the present disclosure. 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 intelligent home platform uses the position coordinate (x) of the refrigerator1,y1) As a dot, drawing a circle 1 with a radius of 1 meter, and a position coordinate (x) of the oven2,y2) As a dot, drawing a circle 2 with a radius of 3 m and a position coordinate (x) of the washing machine3,y3) The circle 3 is drawn as a dot with a radius of 5 m. The position coordinates of the intersection point a of the circle 1, the circle 2, and the circle 3 are the position coordinates of the mobile terminal.
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 with a certain point of the house as an origin. Moreover, 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 position coordinates of a plurality of second intelligent home devices located 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 a room where the mobile terminal is located currently in a house.
In some embodiments, the smart home platform determines a room identifier of a room in which the mobile terminal is currently located in the house based on the location coordinates of the mobile terminal to obtain a room identifier of the target room. The intelligent home platform acquires the equipment identifications of the plurality of second intelligent home equipment in the target room from the stored corresponding relation between the room identifications and the equipment identifications based on the room identifications of the target room. Based on the above description, the smart home platform further stores the correspondence between the device identifiers and the position coordinates of the smart home devices, 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 stored correspondence between the device identifiers and the position coordinates based on the device identifiers of the plurality of second smart home devices. And then, sending the position coordinates of the mobile terminal and the position coordinates of the plurality of second smart home devices to the mobile terminal.
The intelligent home platform stores the position coordinate ranges of all rooms in the house, so that the intelligent home platform can compare the position coordinate of the mobile terminal with the position coordinate ranges of all rooms in the house to determine the room identification of the target room. That is, if the location coordinate of the mobile terminal falls within the location coordinate range of a certain room, the room identification of the room is determined as the room identification of the target room.
It should be noted that the position coordinate range of each room in the house is determined in advance by the smart home platform based on the ground size of each room in the house and the ground shape of the room. That is, the smart home platform stores a space division map (also referred to as a house map) of the house, establishes a coordinate system with a certain point in the space division map of the house as an origin, determines a first minimum distance and a first maximum distance of the room from the origin of the coordinate system in the horizontal axis direction based on the floor size of the room when the floor shape of the room is a square or a rectangle, determines the first minimum distance as a minimum abscissa of a position coordinate range of the room, and determines the first maximum distance as a maximum abscissa of the position coordinate range of the room. Similarly, a second minimum distance and a second maximum distance from the origin of the coordinate system in the direction of the longitudinal axis of the room are determined, the second minimum distance is determined as the minimum longitudinal coordinate of the position coordinate range of the room, and the second maximum distance is determined as the maximum longitudinal coordinate of the position coordinate range of the room, so that the position coordinate range of the room is obtained.
For example, please refer to fig. 4, fig. 4 is a schematic diagram of a space 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 bed in the space division diagram of the house as the origin. Taking the main-lying as an example, the first minimum distance of the main-lying from the origin of the coordinate system in the horizontal axis direction is 0, and the first maximum distance is 3400 mm. Therefore, the minimum abscissa of the main-lying position coordinate range is 0, and the maximum abscissa is 3400. Similarly, the second minimum distance from the origin of the coordinate system in the direction of the longitudinal axis of the main bed is determined to be 0, and the second maximum distance is 4000 mm. Therefore, the minimum ordinate of the position coordinate range of the main bed is 0, and the maximum ordinate is 4000.
The above is described by taking as an example the shape of the floor of the room as square or rectangular. Of course, the floor shape of the room may be other shapes, in which case, the room may have a plurality of coordinate ranges on the horizontal axis and a plurality of coordinate ranges on the vertical axis, which may be determined according to the floor shape of the room.
In addition, the above-described determination of the position coordinate range of each room by the space division diagram of the house is an example. In other embodiments, the information can be determined by the user and reported 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 send 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 located 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 are not needed to be sent to the mobile terminal. That is, the smart home platform can shield the mobile terminal from controlling other smart home devices in the non-target room. Therefore, the mobile terminal can be prevented from carrying out 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 household equipment is configured in the house, the position of the intelligent household equipment is basically unchanged, so that the corresponding relation between the equipment identification and the position coordinate of the intelligent household equipment can be stored. The corresponding relation between the equipment identification and the position coordinate and the corresponding relation between the room identification and the equipment identification are determined in advance by the intelligent home platform. For example, the corresponding relationship between the device identifier and the position coordinate and the corresponding relationship 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, which will be described below and will not be set forth herein.
The room identifier is used to uniquely identify a room, and may be the number, name, floor area, type, etc. of the room, or may be obtained by combining these pieces of information.
For example, please refer to fig. 5, fig. 5 is a schematic diagram of determining a room identifier according to an embodiment of the present application. In fig. 5, the user selects an existing house or a newly-built house through the mobile terminal to determine a space division diagram of the house. If the user determines the space division map of the house via the mobile terminal, each room in the house may be assigned a room identification based on the space division map of the house. If the user does not select the existing house or build a new house through the mobile terminal, that is, the user does not determine the space division diagram of the house through the mobile terminal, the room identifiers of the 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 the plurality of second intelligent home devices in the 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 deviation angles between the mobile terminal and the plurality of second intelligent household devices respectively based on the position coordinates of the mobile terminal and the position coordinates of the plurality of second intelligent household devices, and further determines target intelligent household devices from the plurality of second intelligent household devices based on the deviation angles between the mobile terminal and the plurality of second intelligent household devices respectively. And then, controlling the target intelligent household equipment.
Because the plurality of second smart 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 smart home devices, the deviation angle between the mobile terminal and the second smart home devices is determined by using a horizontal plane where the mobile terminal is located as a reference plane. That is, the deviation angle between the mobile terminal and the second smart home device is an included angle between a connection line between a center point of the mobile terminal and a center point of the second smart home device and a reference plane (horizontal plane).
Since the determining manner of the deviation angle between the mobile terminal and each second smart home device is the same, next, taking one of the second smart home devices as an example, the determining manner of the deviation angle between the mobile terminal and the second smart home device is introduced. For convenience of description, the second smart home device is 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).
Figure BDA0003492426780000141
Wherein, in the above formula (4), θ represents a deviation angle between the mobile terminal and the second smart home device B, and ypRepresents the ordinate of the position coordinate of the second smart home device B, y represents the ordinate of the position coordinate of the mobile terminal, xpAnd x represents the abscissa of the position coordinate of the mobile terminal.
In some embodiments, the implementation process of the mobile terminal determining the target smart home device from the plurality of second smart home devices based on the deviation angles between the mobile terminal and the plurality of second smart home devices respectively includes: in the case that there is at least one second smart home device among the plurality of second smart home devices having a deviation angle from the mobile terminal smaller than the angle threshold value, selecting second intelligent household equipment with the smallest deviation angle with the mobile terminal from the at least one second intelligent household equipment, if the number of the selected second intelligent household equipment is 1, determining the selected second smart home devices as target smart home devices, if the number of the selected second smart home devices is greater than 1, determining the distance between each selected second smart home device and the mobile terminal based on the position coordinates of the mobile terminal and the position coordinates of each selected second smart home device, and determining the second smart home device with the smallest distance between the selected second smart home device and the mobile terminal as the target smart home device.
After the mobile terminal determines the deviation angles between the mobile terminal and the plurality of second intelligent household devices respectively, whether at least one second intelligent household device with the deviation angle between the mobile terminal and the second intelligent household devices being smaller than an angle threshold exists in the plurality of second intelligent household devices is judged. If at least one second intelligent household device with the deviation angle smaller than the angle threshold value does not exist in the plurality of second intelligent household devices, it is indicated that the target intelligent household device does not exist in the plurality of second intelligent household devices, and the operation is finished. If at least one second intelligent household device with the deviation angle smaller than the angle threshold exists in the plurality of second intelligent household devices, it is indicated that the target intelligent household device exists in the plurality of second intelligent household devices. At this time, the mobile terminal selects the second smart home device with the smallest deviation angle with the mobile terminal from the at least one second smart home device. And if only one selected second intelligent household device is available, determining the selected second intelligent household device as the target intelligent household device. And if at least two selected second intelligent household devices exist, determining the second intelligent household device with the minimum distance between the second intelligent household device and the mobile terminal as the target intelligent household 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 within the control range of the mobile terminal. At this time, the mobile terminal may control the smart home device, that is, there is a target smart home device. If the deviation angle between the intelligent household equipment and the mobile terminal is larger than the angle threshold value, it is indicated that the position of the intelligent household equipment does not belong to the control range of the mobile terminal, at the moment, the mobile terminal cannot control the intelligent household equipment, and therefore target intelligent household equipment does not exist.
The user triggers the mobile terminal to control the target intelligent household equipment in a mode that the mobile terminal points to the intelligent household equipment in the house, so that the target intelligent household equipment can be determined through deviation angles between the mobile terminal and the plurality of second intelligent household equipment. Under the condition that the deviation angle between at least two second intelligent household devices and the mobile terminal is minimum, in order to improve the control precision of the mobile terminal on the target intelligent household device, the second intelligent household device with the minimum distance between the at least two second intelligent household devices and the mobile terminal is determined as the target intelligent household device. Therefore, the target intelligent household equipment can be preferentially determined from the at least two second intelligent household equipment.
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).
Figure BDA0003492426780000161
Wherein, in the above formula (5), S represents a distance between the mobile terminal and any selected second smart home device, xqAn abscissa representing a position coordinate of the second smart home device, x represents an abscissa of a position coordinate of the mobile terminal, and y represents an abscissa of a position coordinate of the mobile terminalqAnd y represents the ordinate of the position coordinate of the mobile terminal.
It should be noted that, in the above manner, after the intelligent home platform determines the position coordinates of the mobile terminal and the position coordinates of the plurality of second intelligent home devices, the position coordinates are sent to the mobile terminal. The mobile terminal determines the 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 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 target smart home device may be determined 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, sending the device identification of the target intelligent household device to the mobile terminal. In this way, after the mobile terminal receives the device identifier of the target smart home device sent by the smart home platform, the mobile terminal can control the target smart home device.
The smart home platform determines 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, and the process of determining the target smart home device from the plurality of second smart home devices is similar to the process of determining the target smart home device by the mobile terminal.
After the mobile terminal determines the target intelligent household equipment, the target intelligent household equipment can be controlled in different modes based on the type of the target intelligent household equipment. That is, under the condition that the type of the target smart home device is included in the first type set, the mobile terminal sends a UWB control signal to the target smart home device to control the target smart home device. And under the condition that the type of the target intelligent household equipment is contained in the second type set, the mobile terminal controls the target intelligent household equipment through the intelligent household platform. Thus, more abundant application scenes can be met.
For example, the first type set includes televisions, clothes hangers, and door locks. The second group of types includes air conditioners, ovens, refrigerators, and microwave ovens. When the target smart home device is a door lock, the mobile terminal sends a UWB control signal to the door lock, wherein the type of the door lock is included in the first type set, and the UWB control signal is used for indicating to close the door lock. And after the door lock receives the UWB control signal, the door lock is closed. When the target smart home device is an oven, since the type of the oven is included in the second type set, the mobile terminal sends the device identifier of the oven to the smart home platform through a network device such as a WIFI (Wireless Fidelity) router. After the intelligent home platform receives the equipment identification of the oven, the menu, the cooking mode and the oven state of the oven are obtained from the stored corresponding relation between the equipment identification of the intelligent home equipment and the equipment information, and the menu, the cooking mode and the oven state are sent to the mobile terminal through network equipment such as a WIFI router. After receiving the menu, the cooking mode and the oven state of the 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 the intelligent home platform receives the control instruction, the control instruction is sent to the oven through network equipment such as a WIFI router.
For example, please refer to fig. 6, where 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. The mobile terminal sends the equipment identification of the oven to the intelligent home platform through network equipment such as a WIFI router. After the intelligent home platform receives the equipment identification of the oven, the menu, the cooking mode and the oven state of the oven are obtained from the stored corresponding relation between the equipment identification of the intelligent home equipment and the equipment information, and the menu, the cooking mode and the oven state are sent to the mobile terminal through network equipment such as a WIFI router. After receiving the menu, the cooking mode and the oven state of the 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 the intelligent home platform receives the control instruction, the control instruction is sent to the oven through network equipment such as a WIFI router.
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 clothes through the intelligent home platform. Or the situation of food materials in the refrigerator is acquired through the intelligent home platform, so that a preservation scheme is set and the food materials are supplemented in time.
For example, please refer to fig. 7, where fig. 7 is a schematic diagram of obtaining information through an intelligent home platform according to an embodiment of the present application. In fig. 7, the mobile terminal may obtain a menu, 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 situation of food materials in the refrigerator is acquired through the intelligent home platform, so that a preservation scheme is set and the food materials are supplemented in time.
The first type set is a set formed by types of intelligent household equipment directly controlled by the mobile terminal through a UWB signal, and the second type set is a set formed by types of intelligent household equipment controlled by the mobile terminal through an intelligent household platform. The first type set and the second type set are obtained by the mobile terminal from the intelligent home platform in advance and are stored locally. Namely, after determining the first type set and the second type set, the intelligent home platform directly sends the first type set and the second type set to the mobile terminal for storage.
It should be noted that, when the duration of the time period that the mobile terminal points to the target smart home device is longer than the duration threshold, the mobile terminal may send the UWB control signal to the target smart home device, or control the target smart home device through the smart home platform. Therefore, the mobile terminal can determine whether to continue to control the target intelligent household equipment, and the current operation is avoided being caused by the fact that the user touches the mobile terminal by mistake.
Based on the above description, the smart home platform stores the correspondence between the device identifier and the position coordinate and the correspondence between the room identifier and the device identifier, which may be stored in the process of binding the smart home device by the smart home platform. Therefore, taking the third smart home device as an example, a binding process of the third smart home device will be described next.
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 coordinates, and the room identifier of the room in which the third smart home device is located to the smart home platform. After the intelligent home platform receives the device identifier, the position coordinate and the room identifier of the room in which the third intelligent home device is located, which are sent by the mobile terminal, the device identifier and the position coordinate of the third intelligent home device can be stored in the corresponding relationship between the device identifier and the position coordinate. And simultaneously, storing the equipment identifier of the third intelligent household 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 in which the third smart home device is located in the house, and sends the device identifier, the position coordinate, and the room identifier of the room in which the third smart home device is located 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 in which 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, and the adding interface comprises two options of manual adding and automatic searching. Namely, the user may select to add the third smart home device to be bound manually, or may select to add the third smart home device to be bound through automatic search of the mobile terminal. And if the user selects to manually add the third intelligent household equipment to be bound, the user inputs the name of the third intelligent household equipment to be bound in the input box, and sends a UWB request binding signal to the third intelligent household equipment to be bound when the mobile terminal detects the confirmation operation of the user. 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 the built-in UWB component, and the UWB device binding signal carries the device identifier of the third intelligent home device. And if the user selects to add the third intelligent household equipment to be bound through automatic search of the mobile terminal, the mobile terminal receives a UWB equipment binding signal sent by the third intelligent household equipment to be bound, and the UWB equipment binding signal carries the equipment identifier of the third intelligent household equipment.
The mobile terminal obtains the position coordinates of the third intelligent household device, and the implementation process of the room identifier of the room where the third intelligent household device is located in the house comprises the following steps: the mobile terminal displays a first user interface, the first user interface comprises a space division diagram of a house, and in response to the selection operation of a first position in the space division diagram, position coordinates of the first position and a room identifier of a room where the first position is located are determined, the position coordinates of the first position are determined as the position coordinates of third intelligent household equipment, and the room identifier of the room where the first position is located is determined as the room identifier of the room where the third intelligent household equipment is located in the house. That is, the mobile terminal displays a first user interface including a space division diagram of a house. The user may select a location where the third smart home device is located in the space division diagram, and when the mobile terminal detects a selection operation of the user, the location selected by the user is determined as a first location, and then a location coordinate of the first location and a room identifier of a room where the first location is located are determined, the location coordinate of the first location is determined as a location coordinate of the third smart home device, and the room identifier of the room where the first location is located is determined as a room identifier of a room where the third smart home device is located in the room.
The manner in which the mobile terminal obtains the position coordinates of the third smart home device in the above manner, and the room identifier of the room in which the third smart home device is located in the house 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 according to other manners. Illustratively, when the mobile terminal detects a binding operation of a user, the mobile terminal displays a second user interface, where the second user interface includes an input box corresponding to the position coordinates of the third smart home device and room identifiers of multiple rooms in a house. The user may input the position coordinates of the third smart home device in the input box, and may further select a room identifier of a room in which 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 as the position coordinate of the third intelligent home device, and the room identifier selected by the user is determined as the room identifier of the room where the third intelligent home device is located in the house.
The binding operation of the user can be triggered by voice interaction or by clicking a binding button. For example, the user inputs "bind smart home device" by voice to trigger the binding operation. The confirmation operation of the user can be triggered by voice interaction or by clicking a submit button in the second user interface.
For example, please refer to fig. 8, where fig. 8 is a schematic diagram of binding a third smart home device according to an embodiment of the present application. In fig. 8, the mobile terminal displays a first user interface, and the user adds a third smart home device to a plurality of rooms included in the house. And the mobile terminal determines the position coordinates of the third intelligent household equipment and the room identifier of the room in the house, and acquires the equipment identifier of the third intelligent household equipment through the UWB equipment binding signal sent by the third intelligent household equipment. And then, sending the device identifier, the position coordinates and the room identifier of the room in which the third smart home device is located to the smart home platform.
Optionally, the smart home platform may further store house identifiers of a plurality of houses, where the house identifiers of the plurality of houses correspond to the plurality of houses managed by the mobile terminal one to one. 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 the switching operation of the user, the mobile terminal displays a third user interface, the third user interface comprises house identifications of the plurality of houses, and the user can select one house identification from the plurality of house identifications. And when the mobile terminal detects the confirmation operation of the user, determining the house corresponding to the house identifier selected by the user as the house which needs to be controlled by the intelligent household equipment currently. Then, the mobile terminal controls the smart home devices in the house according to the process of the step 201 and the step 204.
The house identifier is used to uniquely identify the house, and may be the serial number, floor area, type, etc. of the house, or may be obtained by combining these information.
Optionally, in some embodiments, the mobile terminal may further install a smart home APP (Application). 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, because the UWB technology utilizes the extremely narrow pulse of nanosecond to microsecond level to transmit data, 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 household devices in the house through the UWB technology. Then, the intelligent home platform can accurately determine the position coordinates of the mobile terminal and the current room of the mobile terminal in the house based on the distances between the mobile terminal and the plurality of first intelligent home devices. And then the target intelligent household equipment determined by the mobile terminal is accurate, so that the control precision of the mobile terminal on the target intelligent household equipment is improved. In addition, after the mobile terminal determines the target intelligent household equipment, the target intelligent household equipment can be controlled according to different modes based on the type of the target intelligent household 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, more abundant application scenes can be met.
