[0045] The embodiment of the present application provides a device control method. An auxiliary device with a wireless positioning module is used to assist in determining the theoretical position information of the remote control terminal relative to each controlled device. Based on the theoretical position information and the actual position information of the remote control terminal relative to the currently targeted controlled device, the target controlled device currently controlled by the remote control terminal is determined. Thus, without the need for all controlled devices to be equipped with positioning modules, the remote control can have the ability to control different types of devices, which not only improves the compatibility between the remote control terminal and the controlled devices, but also reduces the cost of other controlled devices due to the additional positioning module.

[0049] For ease of understanding, the specific process in the embodiments of this application is described below. Please refer to Figure 1 , Figure 1 which is a schematic flowchart of an embodiment of the device control method provided by the embodiments of this application.

[0050] In Figure 1 the embodiment shown, the method specifically includes the following steps:

[0051] S101, Receive a device control request initiated based on the remote control terminal.

[0052] It should be explained that the remote control terminal used in this solution refers to a conventional remote control or a mobile terminal capable of simulating the functions of a remote control, such as a mobile phone or a tablet computer, etc.

[0053] In this embodiment, when the user needs to operate the controlled device (such as an air conditioner or a TV, etc.) through the remote control terminal, first, a device control request needs to be received and initiated to the remote control terminal. The device control request can be triggered by physical buttons or touchscreens integrated on the remote control terminal. It can also be triggered by inputting voice commands through a voice control module integrated on the remote control terminal, etc., without limitation here.

[0054] S102, According to the device control request, use an auxiliary device with a wireless positioning module to determine the current first position coordinates of the remote control terminal.

[0055] It should be explained that the positioning module can be a UWB (Ultra Wide Band, a wireless carrier communication technology), or a StarFlash dongle (a small external device, usually connected to a computer or other devices through a USB interface, used to provide additional functions or connectivity), or other modules that can achieve positioning through positioning technology, without limitation here.

[0056] In this embodiment, an auxiliary device with a wireless positioning module (such as a TV, an air conditioner, or any one of the controlled devices) can assist in determining the current first position coordinates of the remote control terminal. Meanwhile, the obtained first position coordinates can be stored locally in the remote control terminal or in a cloud server.

[0057] S103. According to the first position coordinates and the second position coordinates of the controlled device pre-bound to the remote control terminal, calculate the theoretical position information of the remote control terminal relative to each of the controlled devices respectively.

[0058] It should be explained that the theoretical position information refers to the position information calculated according to a certain rule or algorithm when the current first position coordinates of the remote control terminal and the second position coordinates of the controlled device are known. The theoretical position information may include distance, direction angle, etc., which will be described in detail below.

[0059] S104. Compare each of the theoretical position information with the actual position information of the remote control terminal relative to the currently specified target controlled device one by one, and determine the target theoretical position information that meets the preset conditions from the comparison results.

[0060] It should be explained that the actual position information refers to the position information of the remote control terminal relative to the currently specified target controlled device. The actual position information may include distance, direction angle, etc., but needs to correspond to the same category as the theoretical position information, which will be described in detail below.

[0061] In this embodiment, compare each of the theoretical position information with the actual position information of the remote control terminal relative to the currently specified target controlled device one by one, and determine the target theoretical position information that meets the preset conditions from the comparison results. It should be noted that the actual position information can be obtained through sensors (such as gyroscopes, accelerometers, etc.) built in the remote control terminal.

[0062] S105. Use the controlled device corresponding to the target theoretical position information as the target controlled device currently controlled by the remote control terminal, and switch the control interface on the remote control terminal to the target control interface corresponding to the target controlled device.

[0063] In this embodiment, use the controlled device corresponding to the target theoretical position information as the target controlled device currently controlled by the remote control terminal. Switch the control interface on the remote control terminal to the target control interface corresponding to the target controlled device. The target control interface may include device status, control options, etc.

[0064] For example, assume that a user has three smart devices in a room: a TV, an air conditioner, and a light. The user presses the "Control" button on the remote control terminal to initiate a device control request for one of the smart devices. After analysis, the TV is taken as the target controlled device for the current control. At this time, the control interface of the remote control terminal is automatically switched to the TV control interface, and options such as the TV's power on / off, volume adjustment, and channel selection are displayed through the TV control interface.

[0065] An auxiliary device with a wireless positioning module is used to assist in determining the theoretical position information of the remote control terminal relative to each controlled device. Based on the theoretical position information and the actual position information of the remote control terminal relative to the currently targeted controlled device, the target controlled device currently controlled by the remote control terminal is determined. Thus, without the need for all controlled devices to have positioning modules, the remote control can be made capable of controlling different types of devices, which not only improves the compatibility between the remote control terminal and the controlled devices but also reduces the cost incurred by other controlled devices due to the additional positioning module. And there is no need for the user to manually switch the control interface when switching to control different controlled devices, thereby enhancing the user experience.

[0066] In some embodiments, calculating the second position coordinates of the controlled device pre-bound to the remote control terminal according to the first position coordinates includes:

[0067] Controlling the remote control terminal to emit two non-parallel rays at different positions towards the controlled device, namely the first ray and the second ray;

[0068] Determining the midpoint position coordinates of the straight line with the shortest distance between the first ray and the second ray;

[0069] Taking the midpoint position coordinates as the second position coordinates of the controlled device.

[0070] As Figure 2 shown, in this embodiment, when initially determining the second position coordinates of the controlled device, it is necessary to ensure that the parameters involved in calculating the theoretical position information are obtained based on the same coordinate system. In this embodiment, the coordinate system is established with the position of the auxiliary device (Device 2) as the origin. The specific steps for calibrating the second position coordinates of the controlled device are as follows:

[0071] (1) Enter the device position calibration mode, and the remote control terminal provides a screen guide;

[0072] (2) The user manipulates the remote control terminal (smart remote control) to align it with the controlled device (Device 1) within a set distance range and triggers the first calibration. When determining whether it is aligned with the controlled device, the laser scan on the remote control can be used to make the laser point fall on the device;

[0073] (3) Move the remote control terminal within the required distance range, continue to aim at the controlled device, and make the laser point as close as possible to the point in step (2) until the remote control terminal gives a prompt to remind the user that they can press the second calibration to start triggering the second calibration. To make the parameters required for calculating the second position coordinates of the controlled device obtain unique values and conform as much as possible to the actual position where the controlled device is located, the condition for the remote control terminal to prompt that the second calibration can be triggered is that the first ray L1 and the second ray L2 are not parallel to each other, and the horizontal angle projected on the horizontal plane of the space coordinate system is greater than 45°.

[0074] (4) Determine the midpoint position coordinates of the straight line with the shortest distance between the first ray and the second ray, and use the midpoint position coordinates as the second position coordinates of the controlled device.

[0075] In some embodiments, the determining the midpoint position coordinates of the straight line with the shortest distance between the first ray and the second ray includes:

[0076] Obtain the emission position coordinates of the first ray and the second ray respectively;

[0077] According to the emission position coordinates, determine the midpoint position coordinates of the straight line with the shortest distance between the first ray and the second ray;

[0078] Use the midpoint position coordinates as the second position coordinates of the controlled device.

[0079] In this embodiment, the midpoint position coordinates of the straight line with the shortest distance between the first ray and the second ray are used as the second position coordinates of the controlled device. Assume that the auxiliary device is a device equipped with a UWB module. Then the emission position coordinates of the first ray and the second ray are calculated based on the auxiliary device and the UWB module installed in the remote control terminal. Since this technology is a known and mature technology, this solution will not be elaborated.

[0080] In some embodiments, the according to the emission position coordinates, determining the midpoint position coordinates of the straight line with the shortest distance between the first ray and the second ray includes:

[0081] Obtain the first horizontal angle and the first pitch angle of the first ray relative to the remote control terminal, and the second horizontal angle and the second pitch angle of the second ray relative to the remote control terminal;

[0082] Substitute the emission position coordinates, the first horizontal angle, the first pitch angle, the second horizontal angle, and the second pitch angle into a preset midpoint determination algorithm for calculation to obtain the midpoint position coordinates of the straight line with the shortest distance between the first ray and the second ray.

[0083] As Figure 3As shown in the figure, in this embodiment, it is assumed that point A is the position where the remote control terminal is calibrated for the first time, and point B is the position where the remote control terminal is calibrated for the second time. That is, point A and point B are the emission positions of the first ray and the second ray emission points respectively. The auxiliary device selects any controlled device equipped with a UWB module. At the same time, a UWB module corresponding to the auxiliary device is installed in the remote control terminal. The polar coordinate values of point A and point B relative to the auxiliary device can be calculated by the UWB module installed in the remote control terminal. Since this technology is a known and mature technology, this solution will not be elaborated. Let the coordinates of point A be The coordinates of point B are The first ray and the second ray are L1 and L2 respectively.

[0084] Convert the spherical coordinates to Cartesian coordinates:

[0085]

[0086] Get A(x1, y1, z1)

[0087]

[0088] Get B(x2, y2, z2)

[0089] Let α and β be the first horizontal angle and the first pitch angle at which the first ray L1 passes through point A, and γ and δ be the second horizontal angle and the second pitch angle at which the second ray L2 passes through point B. α and β, γ and δ can be directly given by modules such as gyroscopes and electronic compasses installed in the remote control terminal for measuring angles and directions. This part is a mature and known technology, and this solution will not be elaborated.

[0090] Then the direction vector of the first ray L1 can be expressed as The direction vector of the second ray L2 can be expressed as

[0091]

[0092] Let point p1 be on the first ray L1, point p2 be on the second ray L2, and the distance between p1 and p2 is the shortest. and can be respectively obtained through and the direction vector and be expressed as:

[0093]

[0094] where t and u are parameters.

[0095] According to the vector property, when the distance between p1 and p2 is the shortest, then and and are both perpendicular, we get:

[0096]

[0097] Substitute into the above two formulas, we get a system of linear equations about t and u:

[0098]

[0099] Solve it according to Cramer's rule:

[0100]

[0101]

[0102] If D = 0, the first ray is parallel to the second ray, and recalibration is required; if D ≠ 0, the two lines are not parallel, and there is a unique solution for t and u, we get:

[0103]

[0104] After obtaining t and u, substitute them back into the above and expressions, and the coordinates of p1 and p1 points are:

[0105]

[0106] and The coordinates of the midpoint M are

[0107] Express the coordinates of M as (x M , y M , z M )

[0108]

[0109] After t and u are calculated according to the above steps, they only contain variables x1, y1, z1, x2, y2, z2, a1, b1, c1, a2, b2, c2;

[0110] x1 = r1 * sinθ1cosφ1, y1 = r1 * sinθ1sinφ1, z1 = r1 * cosθ1

[0111] x2 = r2 * sinθ2cosφ2, y2 = r2 * sinθ2sinφ2, z2 = r2 * cosθ2

[0112] a1 = sinβcosα, b1 = sinβsinα, c1 = cosβ;

[0113] a2 = sinδcosγ, b2 = sinδsinγ, c2 = cosδ;

[0114] where r1, θ1, φ1 and r2, θ2, φ2 can be obtained by the UWB module in the remote control terminal; α and β, γ and δ can be obtained by the gyroscope and electronic compass in the remote control terminal. According to the above calculation steps and the above known values, the specific values of M(x M , y M , z M ) can be obtained. The coordinates of point M obtained can be regarded as the second position coordinates of the controlled device.

[0115] In some embodiments, the theoretical position information includes a theoretical horizontal angle and a theoretical pitch angle. Calculating the theoretical position information of the remote control terminal relative to each of the controlled devices according to the first position coordinates and the second position coordinates of the controlled devices pre-bound to the remote control terminal respectively includes:

[0116] Determining the connection lines between the remote control terminal and each of the controlled devices according to the first position coordinates and each of the second position coordinates;

[0117] Respectively determining the theoretical horizontal angle and the theoretical pitch angle corresponding to each of the connection lines.

[0118] In this embodiment, after the position calibration of the controlled device is completed according to the above method, any controlled device that has been calibrated can be controlled using the remote control terminal. When the remote control terminal points to the device, the control of the device pops up on the display screen of the remote control, and the user can perform the control. The steps for determining whether the remote control has pointed to the calibrated device are as follows:

[0119] Obtaining the current coordinates of the remote control:

[0120] The coordinates C(r3, θ3, φ3) of the current first position (hereinafter referred to as point C) of the remote control terminal obtained from the UWB module in the remote control terminal are converted into Cartesian coordinates C(x C , y C , z C ):

[0121] x C = r3*sinθ3cosφ3, y C = r3*sinθ3sinφ3, z C = r3*cosθ3

[0122] Calculate the theoretical horizontal angle and the theoretical pitch angle of the connection line L3 formed by the remote control terminal (point C) and each controlled device (hereinafter referred to as point M). And σ, the steps are as follows:

[0123] Calculate the direction vector

[0124] Calculate the direction cosine: The direction cosine is the cosine value of the angle between the vector and each coordinate axis. Let The direction cosine of be (cosα c , cosβ c , cosγ c ), then:

[0125]

[0126] The theoretical horizontal angle is the angle between the projection of the vector on the xy plane and the positive direction of the x axis. According to the direction cosines cosα c and cosβ c , we get:

[0127]

[0128] If x M = x C , (if y M - y C > 0) or (if y M - y C < 0)

[0129] The theoretical pitch angle σ: The theoretical pitch angle σ is the angle between the vector and the positive direction of the z axis (the z axis is upward as the positive direction). According to the direction cosine cosγ c and (that is The projection length on the xy plane), we get:

[0130]

[0131] If z C = z M , σ = 0 or σ = π.

[0132] In some embodiments, the comparing each of the theoretical position information with the actual position information of the remote control terminal relative to the currently targeted controlled device, and determining the target theoretical position information that meets the preset conditions from the comparison results includes:

[0133] Compare each of the theoretical position information with the actual position information of the remote control terminal relative to the target controlled device currently pointed at, and determine the target theoretical position information with the highest similarity to the actual position information from the comparison results.

[0134] In this embodiment, the theoretical position information with the highest similarity to the actual position information can be determined from the comparison results as the target theoretical position information. It can be understood that the similarity calculation method can be calculated using the cosine similarity algorithm. Since this algorithm is a conventional technology, it will not be elaborated here.

[0135] In some embodiments, the actual position information includes an actual horizontal angle and an actual pitch angle. The step of comparing each of the theoretical position information with the actual position information of the remote control terminal relative to the target controlled device currently pointed at, and determining the target theoretical position information that meets the preset conditions from the comparison results includes:

[0136] Compare each of the theoretical position information with the actual position information of the remote control terminal relative to the target controlled device currently pointed at, and determine the target theoretical position information that simultaneously satisfies that the difference between the theoretical horizontal angle and the actual horizontal angle is less than or equal to a first preset threshold, and the difference between the theoretical pitch angle and the actual pitch angle is less than or equal to a second preset threshold from the comparison results.

[0137] In this embodiment, the actual horizontal angle of the current remote control terminal is read from the gyroscope and electronic compass module in the remote control terminal and the actual pitch angle ρ. Compare each of the theoretical position information with the actual position information of the remote control terminal relative to the target controlled device currently pointed at, and determine the theoretical position information that simultaneously satisfies that the difference between the theoretical horizontal angle and the actual horizontal angle is less than or equal to a first preset threshold, and the difference between the theoretical pitch angle and the actual pitch angle is less than or equal to a second preset threshold as the target theoretical position information.

[0177] The memory 120 can be used to store software programs and modules, such as the program instructions / modules corresponding to the device control method in the above embodiments. The processor 180 executes various functional applications and data processing by running the software programs and modules stored in the memory 120, and can automatically select a vibration reminder mode for device control according to the current scenario where the electronic device is located, which can not only ensure that the meeting and other scenarios are not disturbed, but also ensure that the user can perceive incoming calls, improving the intelligence of the electronic device. The memory 120 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memories, or other non-volatile solid-state memories. In some instances, the memory 120 may further include a memory remotely provided with respect to the processor 180, and these remote memories can be connected to the electronic device 1200 through a network.

Specifically, the input unit 130 may include a touch-sensitive surface 131 and other input electronic devices 132. The touch-sensitive surface 131, also known as a touch display screen or a touchpad, can collect touch operations of the user on or near it (such as operations of the user using a finger, a stylus, or any suitable object or accessory on or near the touch-sensitive surface 131), and drive the corresponding connection device according to a pre-set program. Optionally, the touch-sensitive surface 131 may include two parts: a touch detection device and a touch controller. Among them, the touch detection device detects the touch orientation of the user, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into touch point coordinates, and then sends it to the processor 180, and can receive and execute the commands sent by the processor 180. In addition, the touch-sensitive surface 131 can be implemented in multiple types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch-sensitive surface 131, the input unit 130 may further include other input electronic devices 132.

The audio circuit 160 can transmit the electrical signal converted from the received audio data to the speaker 161, and the speaker 161 converts it into a sound signal for output; on the other hand, the microphone 162 converts the collected sound signal into an electrical signal, which is received by the audio circuit 160 and then converted into audio data. After the audio data is output to the processor 180 for processing, it is sent through the RF circuit 110 to, for example, another terminal, or the audio data is output to the memory 120 for further processing. The audio circuit 160 may further include an earphone jack to provide communication between the peripheral earphone and the electronic device 1200.
