With the development of science and technology, intelligent furniture has become popular. In the related art, when a plurality of smart devices exist in a user room, if it is necessary to control the plurality of devices by voice, different names need to be set for the respective devices. For example, when a plurality of independent fluorescent lamps are installed in a living room, the fluorescent lamps may be named as a fluorescent lamp 1 and a fluorescent lamp 2.

With the development of science and technology, intelligent furniture has become popular. In the related art, when a plurality of smart devices exist in a user room, if it is necessary to control the plurality of devices by voice, different names need to be set for the respective devices. For example, when a plurality of independent fluorescent lamps are installed in a living room, the fluorescent lamps may be named as a fluorescent lamp 1 and a fluorescent lamp 2. However, when the number of devices that need to be controlled increases to a certain extent, a plurality of different names need to be set. When a user sets, the setting steps are very complicated. In addition, during control, the device name needs to be added to all control instructions, for example, when the fluorescent lamp 1 needs to be controlled to be turned off through semantic control, the voice control instruction needing to be input is to turn off the fluorescent lamp 1, and when the control instruction of turning off is directly sent out, the control target cannot be determined. This also results in a very cumbersome control procedure. Therefore, the related intelligent device control scheme has the defect of complicated control steps.
In order to solve the foregoing defects in the prior art, an embodiment of the present invention provides a method for controlling an apparatus, where the method for controlling an apparatus is applied to a control terminal. It is understood that the control terminal may be, for example, a remote controller or a wearable device. Wherein, wearing equipment can be intelligent bracelet, intelligent glasses or intelligent earphone etc.. The present embodiment does not specifically limit the specific type of the control terminal.
Further, referring to fig. 3, the control terminal 10 includes a first ranging unit 11a and a second ranging unit 11 b. Wherein the first distance measuring unit 11a and the second distance measuring unit 11b are arranged at intervals. I.e. there is a certain separation distance between the first and second ranging units 11a, 11 b. The size of the distance between the first ranging unit 11a and the second ranging unit 11b is not particularly limited in this embodiment.
It is understood that the spaced distance between the first ranging unit 11a and the second ranging unit 11b may be fixed. For example, referring to fig. 4, when the control terminal 10 is provided as a smart eye, the first ranging unit 11a and the second ranging unit 11b may be respectively provided at both sides of the frame. Thus, the first ranging unit 11a and the second ranging unit 11b are made to be a fixed distance. Referring to fig. 5, when the control terminal 10 is set as the smart tws headset, the headset 10 may include a first sub-headset and a second sub-headset on which the first ranging unit 11a and the second ranging unit 11b are respectively disposed. When different users wear the earphone, the distance between the first sub earphone and the second sub earphone is different because of different bone widths of the users. Or the earphones are in different states (such as a wearing state and a non-wearing state), the distance between the first sub earphone and the second sub earphone is different, so that the distance between the first distance measuring unit 11a and the second distance measuring unit 11b arranged on the first sub earphone and the second sub earphone is changed along with the change of the distance between the first sub earphone and the second sub earphone.
In this embodiment, when a plurality of devices to be controlled exist in a space where the control terminal is located, the control terminal may first obtain an angle value of a detection angle corresponding to each device to be controlled. The equipment to be controlled can be intelligent furniture such as an intelligent air conditioner, an intelligent television and an intelligent electric lamp. Or other intelligent devices which can be controlled by the control terminal. The detection angle is an included angle between a straight line where the first distance measuring unit and the second distance measuring unit are located, a middle point between the first distance measuring unit and the second distance measuring unit and a straight line where the equipment to be controlled is located.
Illustratively, referring to fig. 3, in a space where the control terminal 10 is located, there are a device to be controlled a and a device to be controlled B. Wherein, the detection angle corresponding to the device A to be controlled is theta2The corresponding detection angle of the device B to be controlled is theta1。
For convenience of calculation, the detection angle is generally set to be an angle smaller than or equal to 90 ° in an included angle between a straight line where the first ranging unit and the second ranging unit are located and a straight line where the device to be controlled is located and a midpoint between the first ranging unit and the second ranging unit, and is used as the detection angle.
Specifically, when obtaining the angle value of the detection angle corresponding to each device to be controlled, a first separation distance between the first distance measuring unit and the device to be controlled and a second separation distance between the second distance measuring unit and the device to be controlled may be obtained first, a third separation distance between the first distance measuring unit and the second distance measuring unit may be obtained, and then the angle value of the detection angle may be determined according to the first separation distance, the second separation distance, and the third separation distance.
Wherein the third spacing distance is a fixed constant when the distance between the first ranging unit and the second ranging unit is fixed, and thus may be previously stored in a storage medium. So that it is possible to read a pre-stored separation distance as the third separation distance. Otherwise, the third distance may be obtained by a preset distance measurement method.
Referring to fig. 6, fig. 6 is a simplified diagram of relative position relationships between the devices a and B to be controlled and the first ranging unit and the second ranging unit in fig. 3. The point A is the position of the device A to be controlled, the point B is the position of the device B to be controlled, the point O is the position of the first ranging unit, and the point P is the position of the second ranging unit.
It is understood that when the angle value of the detection angle θ 1 needs to be obtained, the first spacing distance L1A, the second spacing distance L2A, and the third spacing distance L3 may be obtained first. Further, point a, point O, and point P constitute a triangular AOP having sides L1A, L2A, and L3. And detecting the angle value of the angle theta 1, namely the angle value of &. Because G is the midpoint of the line segment OP, the length of the line-out segment AG can be calculated according to the triangle central line theorem, and then the cosine value of ≤ AGO can be calculated according to the cosine theorem. Therefore, the angle value of the ≤ AGO, namely the angle value of the detection angle θ 1, is obtained based on the cosine value of the ≤ AGO.
Similarly, based on L1B, L2B, and L3, an angle value of the detection angle θ 2 can be calculated.
As an optional implementation scheme, when a first separation distance between the first ranging unit and the device to be controlled and a second separation distance between the second ranging unit and the device to be controlled are obtained, if the first ranging unit and the second ranging unit are radio frequency ranging units, the first separation distance may be determined according to a first flight time of a radio frequency signal between the first ranging unit and the device to be controlled, and the second separation distance may be determined according to a second flight time of the radio frequency signal between the second ranging unit and the device to be controlled.
After determining the flight time t of the radio frequency signal between two points, the distance s between the two points can be calculated based on the following formula:
s＝t*c
c is the propagation velocity of the radio frequency signal.
For example, the first ranging unit may be configured as a bluetooth ranging unit or a ZigBee ranging unit, and when performing ranging, a ranging signal may be transmitted first, and then the flight time of the radio frequency signal may be determined according to a time point of receiving a feedback signal of the ranging signal and a time point of transmitting the ranging signal.
It should be noted that, when the distance between the first ranging unit and the second ranging unit is not fixed, the separation distance between the first ranging unit and the second ranging unit may also be obtained based on the above method.
Further, after the angle value of the detection angle corresponding to each device to be controlled is obtained, the device to be controlled, in which the corresponding angle value of the detection angle is within a preset range, may be used as a target device to be controlled, and then the received control instruction is sent to the target device to be controlled.
As an alternative embodiment, the preset range may be set to [90 ° -a,90+ a ° ], wherein a may be set to any one of values from 0 to 10. When a user needs to control the target device to be controlled through the control terminal, the detection angle corresponding to the target device to be controlled can be within the preset range through the mobile control terminal, and then the target device to be controlled can be controlled.
Exemplarily, referring to fig. 3, the control terminal is a remote controller, the remote controller includes a voice input control button 12, and when a user needs to control the device B to be controlled, the remote controller may be oriented to control the device B to be controlled, so that an angle value of a detection angle corresponding to the device B to be controlled is 90 °. And then the user can input a voice control instruction by pressing the voice input control, and when the remote controller receives the voice control instruction, the voice control instruction is sent to the equipment B to be controlled.
Referring to fig. 4, when the device to be controlled is glasses, when a user wears the glasses, the user only needs to face the target device to be controlled, and the target device to be controlled can be controlled.
In the technical scheme disclosed in this embodiment, angle values of detection angles corresponding to the devices to be controlled are obtained first, where the detection angles are included angles between straight lines where the first ranging unit and the second ranging unit are located and a straight line where a midpoint between the first ranging unit and the second ranging unit and the device to be controlled are located, then the devices to be controlled, where the corresponding angle values of the detection angles are within a preset range, are used as target devices to be controlled, and received control instructions are sent to the target devices to be controlled. The target equipment to be controlled can be determined according to the angle value of the detection angle and controlled, so that the user can control the equipment to be controlled only by changing the angle value of the detection angle between the terminal equipment and the target equipment to be controlled, and the effect of simplifying the control steps of the equipment control scheme is achieved.
Optionally, based on the foregoing embodiment, in another embodiment, referring to fig. 3 or fig. 4, the control terminal is provided with a control plane. It is understood that, when the device to be controlled is controlled by the control terminal, the device generally set to the control surface orientation is the device that the user wants to control. For example, when the terminal is controlled by a remote controller as shown in fig. 3, the control surface is in front of the remote controller, so that the device to be controlled to which the control surface points is set as the target device to be controlled. When the control terminal is the intelligent glasses shown in fig. 4, the side of the mirror surface of the glasses, which is far away from the user, is the control surface, so that when the user controls a device through the intelligent glasses, the control can be realized only by sending a control instruction to the device.
Based on the solutions disclosed in the above embodiments, referring to fig. 7, when the device C to be controlled and the device C' to be controlled exist on the front side and the back side at the same time, the device C to be controlled is the device C to be controlled that the user wants to control. However, in this case, the angle values of the inspection angles corresponding to the device to be controlled C and the device to be controlled C' are both within the preset range, which results in the control terminal screen determining that a plurality of target devices to be controlled exist at this time. That is, the control terminal determines both the device to be controlled C and the device to be controlled C' as the target device to be controlled, and therefore, it is necessary to determine the device to be controlled to which the control terminal points (faces) as the target device to be controlled. Therefore, a spatial position relationship between each target device to be controlled and the first ranging unit and the second ranging unit can be obtained, wherein the spatial position relationship is an arrangement sequence among the target device to be controlled, the second ranging unit and the first ranging unit based on an arc in which the target device to be controlled, the second ranging unit and the first ranging unit are located. As shown in fig. 7, the target devices to be controlled C on the front side, the second ranging unit and the first ranging unit are arranged in a clockwise order, and the target devices to be controlled C' on the back side, the second ranging unit and the first ranging unit are arranged in a counterclockwise order.
In the technical solution disclosed in this embodiment, the devices to be controlled on the front side of the control terminal and the devices to be controlled on the back side of the control terminal can be distinguished by the spatial position relationship between each of the devices to be controlled and the first ranging unit and the second ranging unit.
Optionally, based on any one of the embodiments described above, in a further embodiment, referring to fig. 8, when there are a plurality of target devices to be controlled that have the same angle value α corresponding to the detection angle. And acquiring the vertical distance between each target device to be controlled and a connecting line between each target device to be controlled and the first ranging unit and the second ranging unit, and then sending the received control command to the target device to be controlled with the minimum vertical distance.
For example, referring to fig. 8, when there are a target device to be controlled D and a target device to be controlled D ' having the same angle value α of the detection angle, the vertical distance corresponding to the device to be controlled D is LD, and the vertical distance corresponding to D ' is LD '. Since LD' is larger than LD. The control instruction can be sent to the device D to be controlled.
Referring to fig. 9, when a plurality of target devices to be controlled, of which the corresponding angle values α are α 1, α 2, and α 3, exist within a preset range (a shaded area in the drawing) corresponding to the angle value of the detection angle. And determining an angle difference corresponding to each target device to be controlled, wherein the angle difference is a difference value between the angle value of the detection angle and a preset angle value, and then sending the received control command to the target device to be controlled, of which the angle difference meets a preset condition. The preset condition may be set as a target device to be controlled, where an absolute value of the difference is the smallest. It is to be understood that the preset condition may also be set to two target devices to be controlled, the absolute value of which is the smallest and the second smallest.
Optionally, referring to fig. 9, based on any one of the above embodiments, in yet another embodiment, the step of obtaining the angle value of the detection angle corresponding to each device to be controlled may be executed when a preset condition is met, where the preset condition includes:
receiving the control instruction; and/or
Detecting that the control terminal moves.
In this embodiment, the target device to be controlled may be determined after receiving the control instruction. Therefore, the control terminal does not need to frequently determine the target equipment to be controlled. The purpose of saving energy is achieved, or the control terminal can be detected to move, so that the control instruction can be immediately sent to the target equipment to be controlled when the control instruction is received, and the effect of improving the response speed of the control instruction is achieved.
In addition, an embodiment of the present invention further provides a control terminal, where the control terminal includes a memory, a processor, and a control program stored in the memory and capable of running on the processor, and the control program, when executed by the processor, implements the steps of the method for controlling the device according to the above embodiments.
Furthermore, an embodiment of the present invention further provides a computer-readable storage medium, where a control program is stored, and the control program, when executed by a processor, implements the steps of the control method of the device according to the above embodiments.
