Detailed Description
The technical scheme provided by the embodiment of the application is described below with reference to the accompanying drawings.
It should be understood that in the description of embodiments of the present application, "/" means or is meant unless otherwise indicated, for example, A/B may represent A or B; "and/or" herein is merely an association relationship describing an association object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone.
In this embodiment, the terms "first", "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present embodiment, unless otherwise specified, the meaning of "plurality" is two or more.
With the rapid development of computer technology, electronic devices are not only of various types, but also are increasingly widely used. For example, in home life, commonly used electronic devices include various types of electronic devices such as televisions, speakers, air conditioners, refrigerators, floor sweeping robots, cameras, desk lamps, and routers. The electronic devices such as televisions, sound boxes, air conditioners, desk lamps and the like support non-contact control (namely support remote control functions) through remote control devices (such as remote controllers), and the electronic devices are very convenient for users to use. Taking a television as an example, a user can conveniently control various types of sound, channels, images and the like of the television through a remote controller.
For electronic devices supporting remote control functions, typically, each electronic device is configured with a dedicated remote control, for example, a television is configured with a remote control 1, an air conditioner is configured with a remote control 2, and a sound box is configured with a remote control 3. It can be appreciated that the user needs to switch back and forth between a plurality of remote controllers when controlling each electronic device, and the user experience is poor. Accordingly, users are increasingly demanding control of a plurality of electronic devices by one remote control device.
Fig. 1 is a schematic diagram of a device control scenario provided in an embodiment of the present application, which illustrates a scenario in which the same remote control device controls different electronic devices at different times. Referring to fig. 1, when there are a plurality of electronic devices controllable by a remote control device, the remote control device needs to determine a target control device from the plurality of electronic devices according to a control operation of a user and establish a connection with the target control device. After the connection is successful, the remote control device may send a control signal to the target control device to control the target control device. Illustratively, the remote control device and the target control device may establish a connection through Bluetooth (BT) technology, or wireless fidelity (Wireless Fidelity, wiFi) peer-to-peer (P2P) technology. It should be noted that a remote control device generally can only determine one target control device at a time, and after establishing a connection with the target control device, a plurality of control signals may be transmitted to the target control device.
It will be appreciated that if the user wants to control other electronic devices via the remote control, the target control device needs to be re-determined. For example, as shown in connection with fig. 1, in the case where the controllable electronic devices include an air conditioner, a television, and a speaker, the remote control device transmits a control signal 1 to the air conditioner to control the air conditioner after determining that the air conditioner is a target control device. If the user wants to control the television, the user needs to determine the television as the target control device again and send a control signal 2 to the television to control the television.
Currently, a remote control device typically determines a target control device from a plurality of electronic devices using Ultra Wide Band (UWB) technology or angle of arrival (AoA) estimation technology. However, UWB technology requires a remote control device to have a UWB chip (see fig. 2A), and AoA estimation technology requires the remote control device to be configured with at least two antennas (see fig. 2B), which results in higher cost of the remote control device, which is not beneficial to popularization and application of the remote control device.
To this end, an embodiment of the present application provides a device determining method capable of determining a target control device from a plurality of electronic devices by an ultrasonic technique, which is helpful for reducing the cost of a remote control device.

Based on the control system provided in each of the above embodiments, an exemplary description is given below of the device determining method provided in the embodiment of the present application.
Firstly, it should be noted that the device determining method provided in this embodiment is based on the remote control device transmitting an ultrasonic signal during the movement process. The present embodiment represents the motion condition of the remote control device by a motion parameter, which may be at least one of distance, speed, acceleration, and the like. The motion parameters determined by other electronic devices according to the received ultrasonic signals are called first motion parameters (such as a first distance, a first speed, a first acceleration, etc.), and the motion parameters detected by the remote control device itself are called second motion parameters (such as a second distance, a second speed, a second acceleration, etc.).
In the present embodiment, referring to S601 to S603 in fig. 6, the apparatus determining method includes: the remote control device transmits ultrasonic signals in the moving process; at least one electronic device receives the ultrasonic signal and determines at least one first motion parameter of the remote control device based on the ultrasonic signal. The remote control device or the at least one electronic device determines a target control device from the at least one electronic device based on the at least one first motion parameter.
The present embodiment classifies the device determination method into two categories:
(1) A centralized device determination method. In the method, the at least one first motion parameter is feature-matched or checked by the remote control device, and the target control device is determined from at least one electronic device.
(2) A distributed device determination method. In the method, the at least one electronic device performs feature matching or verification according to the first motion parameter, and a target control device is determined from the at least one electronic device.
The device determination method provided in this embodiment is described below in an exemplary manner with reference to specific examples, respectively.
Fig. 7 is a schematic flowchart of a device determining method according to an embodiment of the present application, specifically, a centralized device determining method, including the following steps S701 to S715.
S701, the remote control device receives a first user operation.
In the present embodiment, the first user operation is for controlling the remote control device to turn on a function of determining the target control device based on ultrasonic waves (simply referred to as a device selection function).
In some embodiments, the first user operation is an operation in which a user presses/touches a preset button/control on the remote control device. For example, referring to fig. 8A, taking an example in which the remote control device is a remote controller, a first key and other keys are provided on the remote controller, and the first user operation is an operation in which the user presses the first key. Alternatively, as shown in fig. 8B, taking an example in which the remote control device is a mobile phone, the mobile phone is provided with a remote control application (for example, "universal remote control"), and a first control and other controls are displayed on a user interface of the remote control application, where the first user operation is an operation in which a user touches the first control.
In other embodiments, the remote control device may acknowledge receipt of the first user operation upon detecting that it has changed from a stationary state to a moving state (e.g., the remote control device is picked up by the user). It will be appreciated that by this method, the remote control device can turn on the function of determining the target control device based on the ultrasonic waves in accordance with the change in the motion state.
In some other embodiments, the remote control device determines that the first user operation is received after receiving the first voice information to be input by the user. The first voice information may be, for example, a "switch target control device" or the like, which is not limited by the present embodiment.
S702, the remote control device broadcasts a starting instruction.
In this embodiment, the remote control device may broadcast a start instruction to surrounding devices through bluetooth, or broadcast a start instruction to devices in the local area network through WiFi, where the start instruction is used to instruct the electronic device to start the recording function.
S703, at least one electronic device receiving the start instruction starts the recording function.
For example, the electronic apparatuses 1 to 3 each receive a start instruction and respectively start the recording function in response to the start instruction. In other words, taking an example that the electronic device that receives the start instruction includes the electronic devices 1 to 3, and the electronic devices 1 to 3 are mutually trusted with the remote control device, the electronic devices 1 to 3 respectively start the recording function.
It should be noted that, in some embodiments, the device selection function of the remote control device may be in a normally-on state, and the recording function of the at least one electronic device is also in a normally-on state. Based on this, the remote control device and the respective electronic devices may omit S701 to S703, and the target control device may be determined according to the second user operation by directly performing S704.
S704, the remote control device follows the second user operation movement and plays the ultrasonic signal.
In this embodiment, the second user operation may be one-dimensional, two-dimensional or three-dimensional performed by the user holding the remote control device, and the second user operation may be a preset operation or an operation arbitrarily performed by the user. Wherein the remote control device moves in a linear or near linear direction in a one-dimensional motion. In a two-dimensional motion, the remote control device moves in a plane or near plane. Under the three-dimensional action, the remote control device can move along all directions in the three-dimensional space.
It should be noted that the present application does not limit the sequence of playing the ultrasonic signal and following the operation movement of the second user by the remote control device. For example, the remote control device may play the ultrasonic signal immediately after the first user operation is acquired, and follow the second user operation movement for any period of time during which the ultrasonic signal is played. Alternatively, the remote control device may start playing the ultrasonic signal after detecting that the remote control device follows the second user operation movement, and stop playing the ultrasonic signal after detecting that the remote control device is stationary. In other words, in S704, the remote control device may have an ultrasonic signal to be broadcast out during all or part of the following operation movement of the second user.
In one example, as shown in fig. 9, taking the remote control device as a remote controller, the electronic device for starting the recording function is an air conditioner, a television, and a sound box, respectively, if the target control device currently controlled by the remote control device is the air conditioner, but when the user wants to control the television through the remote control device, the remote control device needs to switch the target control device to the television according to the user operation. For example, the user may first press a first key on the remote control device (i.e., the user performs a first user operation) to control the remote control device to play the ultrasonic wave; the user then moves the handheld remote control device closer to the television (i.e., the user performs a second user operation) to select the television as the target control device.
It will be appreciated that the ultrasonic signal played by the remote control device during movement will be doppler shifted, which will cause the frequency of the ultrasonic signal transmitted by the remote control device (i.e. the first frequency) to be different from the frequency of the ultrasonic signal received by the other electronic device (i.e. the second frequency). It should also be appreciated that the second frequency of the ultrasonic signal received by each electronic device may also be different due to the different location of each electronic device relative to the remote control device.
S705, the remote control device determines first time information, which is used to determine a first time period.
The remote control device may be in a motion state or a stationary state during the process of playing the ultrasonic signal. It should be understood that the ultrasonic signal emitted by the remote control device during the movement can be used to make the device determination, and therefore, the present embodiment refers to the ultrasonic signal emitted by the remote control device during the movement as an effective ultrasonic signal and the ultrasonic signal emitted by the remote control device during the rest as an ineffective ultrasonic signal. Based on this, in the present embodiment, the first time information is used to indicate the playing time/receiving time (i.e. the first time period) corresponding to the effective ultrasonic signal.
In the first period, the ultrasonic signal played by the remote control device may be some or all of the ultrasonic signals played by the remote control device, and the ultrasonic signal received by the electronic device may be some or all of the ultrasonic signals received by the electronic device, which is not limited in this embodiment. In addition, the ultrasonic signal in the first period may further include an inactive ultrasonic signal on the basis of the active ultrasonic signal. In summary, it is sufficient that there is a period of the effective ultrasonic signal within the first time period.
In some embodiments, referring to FIG. 10, the first time information includes a start time T 1 And expiration time T 2 Then the first time period corresponding to the first time information is T 1 ～T 2 . Alternatively, the first time information includes a start time T 1 And duration DeltaT, then the first time period corresponding to the first time information is T 1 ～T 1 +Δt. It should be noted that the first time information is generally applicable to a scenario in which the second user operation is a one-dimensional action, for exampleFor example, a user holds the remote control device in a hand to make a straight line or a similar straight line motion near the electronic device.
In this embodiment, alternatively, the remote control device may determine the time at which the first user operation is received as T 1 Distance T 1 The time of the preset duration (such as 3S) is determined as T 2 . Alternatively, the remote control device may determine the first time information based on its movement, e.g., the remote control device may determine the time at which it starts movement as T 1 Determining the time for stopping the motion as T 2 The specific determination manner of the first time information is not limited in this embodiment.
In other embodiments, as shown in FIG. 10, the first time information includes T 1 And T 2 Or T 1 And delta T, can also comprise a characteristic sampling period T S . Wherein T is S The preset parameter may be set, which is not limited in this embodiment. Based on this, in the present embodiment, the remote control device may perform the remote control at every interval T S Dividing an ultrasonic signal emitted in a first time period into an ultrasonic signal period; in addition, the electronic device receiving the ultrasonic signal may also be provided with a T-shaped section S The ultrasonic signal received in the first time period is divided into an ultrasonic signal segment. The first time information is applicable to a scene in which the second user operation is a one-dimensional motion, a two-dimensional motion, or a three-dimensional motion.
S706, the remote control device broadcasts the first time information to at least one surrounding electronic device.
In this embodiment, the remote control device may broadcast the first time information to at least one electronic device around through bluetooth, or broadcast the first time information to at least one electronic device in the local area network through WiFi.
After S704, the remote control device may directly execute S707 without executing S705 to S706. If the remote control device directly performs S707 immediately after S704, then in S707 and subsequent steps, the first time period may be the entire time period for the remote control device to play the ultrasonic signal; for an electronic device receiving an ultrasonic signal, the first time period may be the entire time period during which it receives the ultrasonic signal.
S707, the remote control device determines a second motion parameter of the remote control device during the first period of time.
The motion parameters are used to describe the motion condition of the remote control device, and in this embodiment, the motion parameters of the remote control device may include: at least one of acceleration, speed, distance, etc. Wherein the second motion parameter is a motion parameter of the remote control device determined by the remote control device based on the sensor, for example, a second acceleration, a second speed, a second distance, and the like. The first motion parameter is a motion parameter of the remote control device, such as a first acceleration, a first speed, a first distance, etc., determined by other electronic devices according to the received ultrasonic signal.
In S707, the determination process of the second motion parameter is exemplarily described below with reference to a second user operation of a different dimension, taking a second distance in the second motion parameter as an example.
When the remote control device is moved in proximity to the electronic device (e.g., television) under one-dimensional second user operation, the remote control device may employ either of two ways to determine the second distance that the remote control device is moved.
Mode one: the remote control device detects a second distance of movement of the remote control device using one or more sensors configured with the remote control device. In one example, referring to fig. 11A, the remote control device may use a gyro sensor 406A, an acceleration sensor 406B, and a magnetometer sensor 406C to respectively acquire parameters such as angular velocity, acceleration, and strength and direction of a magnetic field of the remote control device during a first period, and calculate a second distance D of the remote control device during the first period, that is, a total movement distance of the remote control device during the first period, according to the parameters. The specific calculation process can be referred to in the prior art, and this embodiment is not described herein.
Mode two: referring to FIG. 11B, when the first time information includes a characteristic sampling period T S In this case, during a first time period, the remote control device may use the gyro sensor 406A, the acceleration sensor 406B and the magnetometer sensor 406C,at each of the spaced feature sampling periods T S Parameters such as angular velocity, acceleration, strength and direction of a magnetic field of the remote control device are respectively acquired, and the sampling period T of the remote control device in each characteristic is calculated according to the parameters S Distance of movement D within Si I=1, 2, … … N, where N is T comprised in the first period of time S Is a number of (3). It will be appreciated that in this embodiment, the second distance determined by the remote control device includes a distance D corresponding to each sampling period in sequence in the first period Si 。
It should be noted that the movement speed of the remote control device during the first period may not be uniform, and thus the remote control device may not be uniform during each feature sampling period T S Distance of movement D within S May be different.
When the remote control device moves close to the electronic device (e.g. television) under the two-dimensional/three-dimensional second user operation, and the first time information comprises a characteristic sampling period T S When referring to fig. 12, the remote control device may also measure each characteristic sampling period T S Distance of movement D within Si And sequentially corresponding the sampling periods within the first time period to the distances D Si Determining a first distance of the remote control device, i=1, 2, … … N, wherein N is T included in a first period of time S Is a number of (3). The above description about fig. 11B can be referred to specifically, and this embodiment is not repeated here.
And S708, the at least one electronic device determines a target ultrasonic signal in a first time period from the received ultrasonic signals, and determines a first motion parameter of the remote control device in the first time period according to the target ultrasonic signal.
Based on the foregoing description, the first motion parameter is a motion parameter of the remote control device, which is determined by other electronic devices according to the received ultrasonic signal, for example, a first distance, a first speed, a first acceleration, etc. of the motion of the remote control device.
It will be appreciated that the target ultrasonic signals received by the respective electronic devices will typically be different (principally different in frequency) because the remote control device is in motion for a first period of time, and the ultrasonic signals emitted by the remote control device will be doppler shifted, plus the position of the respective electronic devices relative to the remote control device may be different. Each electronic device may determine an estimated value of a motion parameter of the remote control device (i.e., a first motion parameter) during a first time period based on the target ultrasonic signal received by the electronic device, and the first motion parameters determined by each electronic device are typically different.
In one example, when the second user operation is a one-dimensional motion, taking the example that the first motion parameter is a first distance, each electronic device may calculate the first distance that the remote control device moves within the first period of time using the following formula (1).
In the formula (1), see FIG. 11A, D x The estimated movement distance of the remote control device for the other electronic device in the first period (referred to as the first distance in this embodiment), X is used to represent the detection device of the first distance, x=1, 2,3 … …, and so on. F is the frequency of the ultrasonic signal emitted by the remote control device, F S The Doppler shift is measured for the electronic device based on the received ultrasonic signals. C is the transmission speed of sound waves in air. T (T) 1 Is the starting time point of the first time period, T 2 Is the end time point of the first time period. In formula (1), T 2 -T 1 But may also be replaced by the duration deltat of the first time period.
In another example, referring to fig. 11B and 12, when the first motion parameter is a first distance, the first time information includes a feature sampling time T S When the second user operation is a motion of any dimension, the electronic devices can calculate the first distance D of the remote control device in the first time period by adopting the following formula (2) x . In the present embodiment, the first distance D x I.e. T in each characteristic sampling period S Distance D of (2) Si 。
In the formula (2), D XSi The motion distance of the remote control device in the ith Ts in the first period estimated for the other electronic device X, X is used to represent the detection device of the first distance, x=1, 2,3 … …, etc. Illustratively, the electronic device 1 detects a distance D 1Si . F is the frequency of the ultrasonic signal transmitted by the remote control device. F (F) Si Sampling time T for the ith feature of the electronic device in the first time period S The frequency of the received ultrasonic signal is received, i=1, 2,3, … N. C is the transmission speed of sound waves in air. T (T) S1i Is the ith T in the first time period S Start time, T of S1i Is the ith T in the first time period S Is a starting time of (c). In formula (2), T S2i -T S1i May also be replaced by the duration T of the feature sample time S 。
S709, the at least one electronic device broadcasts the first motion parameter.
In this embodiment, each electronic device may broadcast the first motion parameter to surrounding devices through bluetooth, or broadcast the first motion parameter to other devices in the local area network through WiFi. It should be appreciated that the remote control device may receive the first motion parameters broadcast by the respective electronic device via bluetooth or WiFi.
S710, the remote control device receives the first motion parameters broadcast by the electronic devices.
And S711, the remote control device performs feature matching on the second motion parameters and each first motion parameter, and determines the target control device according to the matching result.
In this embodiment, the remote control device may determine, as the target control device, an electronic device corresponding to a first motion parameter that is closest to the second motion parameter and satisfies the threshold value threshold, from among the first motion parameters. Because the motion trail of the remote control device is usually the smallest or 0 ° with respect to the line in which the target device and the remote control device are located, and the included angle between the other devices and the line in which the remote control device is located is larger, the second motion parameter is closest to the first motion parameter of the target device.
The second motion parameter is the second distance D detected by the remote control device, and the first motion parameter is the first distance D detected by other electronic devices X For example, the remote control device may determine the difference Δd between the second distance and the respective first distances, respectively X And will be the smallest and meet Δd of the threshold δ X And the corresponding electronic equipment is determined to be the target control equipment.
It should be noted that, for the one-dimensional second user operation, if the second distance determined by the remote control device is the total movement distance D of the remote control device in the first period, and the first distances determined by the other electronic devices are the total movement distance D of the remote control device in the first period X . Then Δd X ＝|D-D X | a. The invention relates to a method for producing a fibre-reinforced plastic composite. For example, if the electronic devices that can be selectively controlled by the remote control device include the electronic device 1, the electronic device 2, and the electronic device 3, the electronic devices detect that the first distances of the remote control device moving in the first period of time are D respectively 1 、D 2 And D 3 . Then Δd 1 ＝|D-D 1 |，Δd 2 ＝|D-D 2 |，Δd 3 ＝|D-D 3 | a. The invention relates to a method for producing a fibre-reinforced plastic composite. Based on this, if Δd 1 、Δd 2 And Δd 3 The minimum value of (a) is Deltad 2 And Δd 2 <Delta, the remote control device determines the electronic device 2 as the target control device.
And for the second user operation in any one dimension of one dimension, two dimensions and three dimensions, if the second distance determined by the remote control device is the movement distance D in each Ts in the first time period Si And the first distance determined by other electronic devices is the movement distance D of the remote control device in each Ts in the first time period XSi . Then the first time period of the first time period,for example, if the electronic devices that the remote control device can selectively control include electronic device 1, electronic device 2, and electronic device 3, then +.> Based on this, if Δd 1 、Δd 2 And Δd 3 The minimum value of (a) is Deltad 2 And Δd 2 <Delta, the remote control device determines the electronic device 2 as the target control device.
In addition, if the remote control device only receives the first motion parameter sent by one electronic device within the preset time, the remote control device does not need to compare the first motion parameter with the second motion parameter to perform feature matching, and the electronic device corresponding to the first motion parameter can be directly determined to be the target control device.
