[0028] Please see Figure 1 , Figure 1 This is a flowchart illustrating the control method for intelligent home appliances provided in an embodiment of the present invention. The control method for the intelligent home appliances will be described in detail below. Figure 1 As shown, the method includes the following steps S110-S140.

[0029] S110. If a remote control command triggered by the user is received, multiple deviation values ​​of multiple smart home appliances relative to a spatial vector are obtained, wherein the spatial vector is a vector calculated based on the spatial coordinates of the two UWB modules, and one of the UWB modules is installed in the smart home appliance.

[0030] In this embodiment of the invention, the remote control is equipped with at least two UWB (Ultra Wide Band) modules, and one of the multiple smart home appliances is equipped with one of the UWB modules. For ease of understanding, the ranging principle of the UWB module is first introduced: When the UWB module is activated, it generates a timeline. Assuming there are two devices A and B, A sends a communication signal at time TA1, B receives the communication signal at time TB1 and sends a response signal at time TB2, and A receives the response signal at time TA2. Then the distance between A and B is D = ((TA2-TA1)-(TB2-TB1))*c / 2, where c is the speed of light. This distance D is calculated using the time difference and is therefore called the TDOA (Time Difference of Arrival) value. Understandably, the distance between any two devices equipped with UWB modules in space can be calculated using the above principle. Assume we take the extension of the line connecting any device point a to any other device point b as the X-axis, the perpendicular line from device point c to the X-axis as the Y-axis, and the perpendicular point O as the origin of the coordinate system. Establish a three-dimensional coordinate system by drawing the Z-axis perpendicular to the X and Y axes. Given the distances between the three devices as Dab, Dac, and Dbc, we can obtain the specific values ​​of a(Xa, 0, 0), b(Xb, 0, 0), and c(0, Yc, 0). Therefore, for any point R1(x1, y1, z1) and R2(x2, y2, z2) in space, their coordinates can be calculated from their distances to the other three devices. From R1(x1, y1, z1) and R2(x2, y2, z2), we can calculate the spatial vectors of R1 and R2.

[0031] Please see Figure 2 , Figure 2 This is a scene diagram illustrating a control method for smart home appliances provided in an embodiment of the present invention. Figure 2 The system includes three smart home appliances: M1, M2, and M3. M1 and M2 are air conditioners, and M3 is a speaker. Each of M1, M2, and M3 is equipped with a UWB module. Two UWB modules (T1 and T2) in the remote control are positioned along the direction of the remote control signal transmission and are on the same horizontal plane as the transmitter. After powering on M1, M2, M3, and the remote control, T1 and T2 in the remote control continuously communicate with the UWB modules in M1, M2, and M3. At this time, the distance D between the three smart home appliances can be determined through the UWB modules. M12 D M13 D M23 Based on D M12 D M13 D M23 M1(X) can be obtained M1 ,0,0),M2(X M2M3(0, Y) M3 ,0),M1(X M1 ,0,0),M2(X M2 M3(0, Y) M3 (X, 0) represents the spatial coordinates of M1, M2, and M3. M1, M2, and M3 send their device information and spatial coordinates to the remote controller. The remote controller receives the device information and spatial coordinates of M1, M2, and M3, and determines the spatial coordinates (M1(X, 0) based on the spatial coordinates). M1 ,0,0),M2(X M2 M3(0, Y) M3 Calculate the spatial coordinates of the two UWB modules, for example, T1(x11, y11, z11) and T2(x22, y22, z22); calculate the spatial vector V based on the spatial coordinates of the two UWB modules. T1T2 For each smart home appliance, the perpendicular distance between the smart home appliance and the spatial vector is obtained as the deviation value; the deviation value and the device information are saved, that is, the deviation value and the device information are saved in the memory of the remote control. It should be noted that the device information includes device category, device status, and device communication protocol.

[0032] Furthermore, when the user operates the remote control, that is, if the remote control receives a remote control command triggered by the user, it retrieves the spatial vector V of multiple smart home devices from memory. T1T2 Multiple deviation values, such as the deviation values ​​of devices M1, M2, and M3, are P respectively. M1 P M2 and P M3 It should be noted that the smart home appliances mentioned can be one or more of the following: air conditioners, speakers, and washing machines. It should also be noted that if there are only two smart home appliances located close to each other indoors, in order to accurately control both appliances, a standby base station can be set up indoors. This standby base station only performs data communication and has no other functions, nor does it respond to remote control signals.

[0033] S120. Detect whether the multiple smart home appliances are within the remote control path range based on the multiple deviation values.

[0034] In this embodiment of the invention, after obtaining a plurality of deviation values, for each of the plurality of deviation values, the deviation value is compared with a preset deviation value; if the deviation value is not greater than the preset deviation value, the smart home appliance corresponding to the deviation value is set as a smart home appliance that can be remotely controlled within the remote control path range; understandably, if the deviation value is greater than the preset deviation value, the smart home appliance corresponding to the deviation value is set as a smart home appliance that is not remotely controlled within the remote control path range. For ease of understanding, assume that the deviation values ​​of devices M1, M2, and M3 are P respectively. M1 P M2 and P M3 The preset deviation value is P max If P M1 ≤P max Then, device M1 will be set as a smart home appliance that can be remotely controlled within the remote control path range. It can be understood that if P... M1 >P max If so, device M1 is set as a smart home appliance that cannot be remotely controlled within the remote control path range, and devices M2 and M3 are judged according to the above judgment process.

[0035] S130. If there are remotely controllable smart home appliances within the remote control path range, then the target remote control device is determined from the remotely controllable smart home appliances according to the deviation value.

[0036] In this embodiment of the invention, after determining whether multiple smart home appliances are within the remote control path range, if there are remotely controllable smart home appliances within the remote control path range, a target remote control device is determined from the remotely controllable smart home appliances based on the deviation value. Specifically, if there is only one remotely controllable smart home appliance within the remote control path range, that smart home appliance is designated as the target remote control device; if there are multiple remotely controllable smart home appliances within the remote control path range, the smart home appliance with the smallest deviation value is selected from the multiple remotely controllable smart home appliances as the target remote control device. More specifically, when there are remotely controllable smart home appliances within the remote control path range, the number of remotely controllable smart home appliances is obtained. If the number is 1, indicating that there is only one remotely controllable smart home appliance, that smart home appliance is designated as the target remote control device; understandably, if the number is multiple, i.e., greater than or equal to 2, the smart home appliance with the smallest deviation value is selected from the multiple remotely controllable smart home appliances as the target remote control device.

[0037] It should be noted that in this embodiment, if there is no controllable smart home appliance within the remote control path range, an indicator light is turned on, wherein the indicator light is a laser light. It should also be noted that the reason for only turning on the laser light when there is no controllable smart home appliance within the remote control path range is that the remote control will not send a remote control signal, preventing accidental remote control due to wall reflections, etc. Furthermore, it can also provide a prompt to the user, enabling the user to control the smart home appliance more accurately.

[0038] S140. Send a remote control signal according to the acquired device information corresponding to the target remote control device to control the smart home appliance that meets the preset execution conditions to perform the operation corresponding to the remote control signal.

[0039] In this embodiment of the invention, device information corresponding to the target remote control device is obtained. This device information includes device type, device status, and device communication protocol. A remote control signal is sent according to the device communication protocol, so that the smart home appliance receiving the remote control signal verifies whether its own position is within the remote control path range. If its own position is within the remote control path range, it executes the operation corresponding to the remote control signal. Understandably, if the smart home appliance receiving the remote control signal is not within the remote control path range, the operation corresponding to the remote control signal is not executed. It should be noted that the reason for verifying the own position of the smart home appliance receiving the remote control signal is that multiple smart home appliances with the same communication protocol may receive the remote control signal. The data processing module in the smart home appliance determines whether its own position is within the remote control path range. If it is within the remote control path range, it responds to the remote control signal; if it is not within the remote control path range, it does not respond to the remote control signal. It should also be noted that in this embodiment, the device type is an air conditioner, speaker, refrigerator, fan, etc.; the device status is running, standby, etc.; and the device communication protocol varies depending on the device type.

[0040] Furthermore, after sending the remote control signal according to the device communication protocol, the method further includes: displaying the target remote control device; and turning on the indicator light to indicate the landing point of the remote control signal to the user, that is, to remind the user of the target remote control device currently being remotely controlled.

[0041] Please see Figure 3 , Figure 3 This is a simplified flowchart of a control method for a smart home appliance provided in an embodiment of the present invention. Figure 3Among them, the remote control and multiple smart home appliance devices are powered on; the UWB modules installed in the remote control and multiple smart home appliance devices work to determine the relative distances between the smart home appliance devices, calculate the spatial coordinates of each smart home appliance device based on the relative distances between the multiple smart home appliance devices. Each smart home appliance device also obtains its own device information and sends its own device information and spatial coordinates to the remote control. The remote control calculates a spatial vector based on the spatial coordinates and device information of each smart home appliance device, and calculates the deviation value of each smart home appliance device relative to the spatial vector based on the spatial vector; the user starts remote control; whether there are remotely controllable smart home appliance devices within the remote control path; if not, only the laser light is turned on; if so, the target remote control device is determined from the remotely controllable smart home appliance devices for display; a remote control signal is sent according to the device information of the target remote control device, the laser light is turned on, and the landing point of the remote control signal is prompted to the user; the smart home appliance device that receives the remote control signal checks whether its own position is within the remote control path; if it is, it responds to the remote control signal; if not, it does not respond to the remote control signal.

[0042] It should be noted that in this embodiment, whether a smart home appliance device is the device that the user hopes to remotely control is judged according to the deviation value, so as to make a decision on whether to respond to the user's remote control signal, so as to achieve the purpose of precise remote control; the laser light is used to mark the expected landing point of the current remote control signal of the remote control, so as to achieve the purpose of prompting the user about the current remotely controlled device.
