Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In the embodiment of the invention, the wireless device controls the light change of the wireless device, so that the intelligent terminal obtains at least 2 image frames including the light change information of the wireless device, decodes the light change information to obtain the basic information of the wireless device, the basic information of the wireless device includes the address information of the wireless device, and the wireless device receives a connection establishment request sent by the intelligent terminal according to the address information of the wireless device so as to establish connection with the wireless device.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
The first embodiment is as follows:
fig. 1 shows a flowchart of a wireless device connection method according to a first embodiment of the present invention, which is mainly described from a wireless device (such as a bluetooth device or a wifi device) side, and is detailed as follows:
and step S11, the wireless device controls the light change of the wireless device, so that the intelligent terminal obtains at least 2 image frames including the light change information of the wireless device, and decodes the light change information to obtain the basic information of the wireless device, wherein the basic information of the wireless device includes the address information of the wireless device.
Specifically, the wireless device controls the light change of the wireless device after receiving the pairing instruction, for example, the wireless device may be set to start the wireless device as an action of issuing the pairing instruction, the wireless device may also be set to start the wireless device and then press another key as an action of issuing the pairing instruction, and of course, the wireless device may also be set to receive a voice including the pairing instruction as an action of issuing the pairing instruction.
In this step, the intelligent terminal acquires at least 2 image frames including the light change information of the wireless device, which should represent the light change, such as a level change representing the brightness amplitude or the chromaticity amplitude of the light, and preferably, the acquired at least 2 image frames are at least 2 consecutive image frames.
Optionally, the wireless device controls its own light change, specifically including:
a1, the wireless device determines the brightness and/or the chroma of the output light according to a preset modulation mode and the basic information of the wireless device, wherein the preset modulation mode comprises: dividing the amplitude of the brightness and/or the amplitude of the chromaticity of the light into N levels, wherein N is more than or equal to 2, each level corresponds to one piece of information, and amplitude modulation is carried out at a preset frame rate. Specifically, when the modulated information is transmitted in a binary manner, N is equal to 2; when the modulated information is transmitted in a multilevel manner, N is greater than 2. For example, assuming that the brightness of the lamp light is 0 to 255 and N is 2, if 0 to 125 are classified into one class and the value corresponding to the class is 0, and 126 to 255 are classified into another class and the value corresponding to the class is 1, the brightness of the lamp light can be modulated into any one of 0 to 125 when the information to be transmitted is 0.
In this step, the amplitude of the brightness and/or the amplitude of the chromaticity of the light are divided into N levels (2 levels or a plurality of levels), each level corresponds to one piece of information, and the basic information of the wireless device is converted into a corresponding binary value or a multilevel numerical value, so that the level of the amplitude of the brightness and/or the amplitude of the chromaticity of the light corresponding to the basic information of the wireless device can be determined according to the binary value or the multilevel numerical value corresponding to the basic information of the wireless device.
It should be noted that the preset frame rate Fs is less than or equal to half of the frame rate of the smart terminal camera, so that the wireless device can transmit Fs log2(N) bits of data per second.
And A2, the wireless device controls the light of the wireless device to change correspondingly according to the brightness and/or the chromaticity of the light which is determined to be output. In this step, assuming that the brightness of the output lamp light is determined to be 2, 25, 55, 60, the corresponding brightness values are sequentially output according to the determined brightness values.
Further, the a2 specifically includes:
and A21, the wireless device controls the light of the screen backlight of the wireless device to change correspondingly according to the determined brightness and/or chromaticity of the output light. In this step, the wireless device controls its own screen backlight so that the luminance and/or chromaticity of the lamp light output from the screen backlight is the same as the luminance and/or chromaticity of the lamp light determined to be output.
Or,
and A22, the wireless device controls the light change of the indicator light of the wireless device according to the brightness and/or the chromaticity of the light output by the wireless device.
In the above a21 and a22, the screen backlight includes: LED lamps or cold cathode fluorescent lamps CCFL; the indicator light comprises an LED light; the LED lamp is arranged in a screen of the wireless equipment and used as a screen backlight lamp, or the LED lamp is arranged on the side edge or the rear shell of the wireless equipment and used as an indicator lamp. In this step, an LED lamp may be disposed on the wireless device, and the LED lamp may be disposed in a screen of the wireless device, or the LED lamp may be disposed on a side or a rear case of the wireless device. When the LED lamp is arranged in the screen of the wireless equipment, the wireless equipment outputs corresponding light brightness and/or chromaticity by controlling the LED lamp in the screen; when the LED lamp is arranged on the side edge or the rear shell of the wireless equipment, the wireless equipment outputs corresponding light brightness and/or chromaticity by controlling the LED lamp on the side edge or the rear shell of the wireless equipment. When the indicator light or the screen backlight lamp is an LED lamp, the connection speed of the wireless equipment can be improved, and the hardware cost is not increased.
And step S12, the wireless device receives a connection establishment request sent by the intelligent terminal according to the address information of the wireless device so as to establish connection with the intelligent terminal.
In this step, after receiving a connection establishment request sent by an intelligent terminal according to address information of the wireless device, the wireless device identifies whether the intelligent terminal is a legal intelligent terminal, for example, whether the intelligent terminal is a legal intelligent terminal is judged through a preset white list, if so, a connection establishment approval feedback is sent to the intelligent terminal to establish connection with the intelligent terminal, and if not, a connection establishment rejection feedback is sent to the intelligent terminal.
The basic information of the wireless device further includes connection authentication information, and in this case, after step S12, the method includes:
and the wireless equipment receives the connection authentication information sent by the intelligent terminal, verifies the connection authentication information, and selects whether to complete pairing with the intelligent terminal according to a verification result.
After establishing connection with the intelligent terminal, the wireless device receives the connection authentication information sent by the intelligent terminal, and specifically, may verify the received connection authentication information in the following 2 ways: (1) comparing the received authentication information with pre-stored standard connection authentication information, if the received authentication information is the same as the pre-stored standard connection authentication information, completing pairing operation with the intelligent terminal, and if the received authentication information is different from the pre-stored standard connection authentication information, refusing to complete pairing with the intelligent terminal; (2) the intelligent terminal obtains a first operation result after carrying out certain operation on the received connection authentication information, obtains a second operation result after carrying out the same operation on the standard connection authentication information, judges whether the first operation result is equal to the second operation result, finishes pairing operation with the intelligent terminal if the first operation result is equal to the second operation result, and refuses to finish pairing with the intelligent terminal if the first operation result is different from the second operation result. For example, assume that the wireless device receives connection authentication information "a'" sent by the smart terminal; the first operation result obtained after a certain operation is f (A '), the standard connection authentication information is A, the second operation result obtained after the same operation is f (A), and whether f (A') is equal to f (A) is judged. Of course, the smart terminal may also directly transmit the first operation result f (a ') to the wireless device after operating "a'", which is not limited herein.
In the first embodiment of the present invention, a wireless device controls its own lighting change, so that an intelligent terminal obtains at least 2 image frames including lighting change information of the wireless device, and decodes the lighting change information to obtain basic information of the wireless device, where the basic information of the wireless device includes address information and connection authentication information of the wireless device, and the wireless device receives a connection establishment request sent by the intelligent terminal according to the address information of the wireless device, and after establishing a connection with the intelligent terminal, receives the connection authentication information sent by the intelligent terminal, so as to complete pairing with the intelligent terminal. Because the wireless device and the intelligent terminal are realized by controlling the light change of the wireless device and the intelligent terminal to be matched in the process of establishing connection and pairing, the user operation is simplified, and the good experience of the user is improved.
It should be understood that, in the embodiment of the present invention, the sequence numbers of the above-mentioned processes do not mean the execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiment of the present invention.

B2, the intelligent terminal tracks the positioned light emitting areas and counts the brightness and/or chroma values of the light emitting areas in each image frame. Specifically, the intelligent terminal tracks the position offset of the light emitting area between frames of at least 2 image frames, and counts the brightness and/or chromaticity values of the light emitting area in each frame.
B3, decoding the light change information according to the statistical brightness value and/or chromatic value and a preset modulation mode to obtain the basic information of the wireless device, wherein the basic information of the wireless device comprises the address information of the wireless device; the preset modulation mode comprises the following steps: dividing the amplitude of the brightness and/or the amplitude of the chromaticity of the light into N levels, wherein N is more than or equal to 2, each level corresponds to one piece of information, and amplitude modulation is carried out at a preset frame rate. Because each grade corresponds to one piece of information in the preset modulation mode, after the brightness value and/or the chromatic value are determined, the grade corresponding to the brightness value and/or the chromatic value can be determined, and then the information corresponding to the brightness value and/or the chromatic value can be determined, so that the decoding of the lamplight change information is realized.
And step S23, the intelligent terminal sends a connection establishment request to the wireless device according to the address information of the wireless device so as to establish connection with the wireless device.
In this step, after the intelligent terminal sends a connection establishment request to the wireless device, if receiving a connection establishment approval feedback sent by the wireless device, the intelligent terminal successfully establishes a connection with the wireless device.

In the second embodiment of the invention, in the process of establishing connection and pairing between the wireless equipment and the intelligent terminal, the wireless equipment controls the light change of the wireless equipment to be matched with the intelligent terminal, so that the user operation is simplified, and the good experience of the user is improved.
