The example of the consistent device and method of some aspects be described in detail in claims, the disclosure.
Fig. 1 is the structure diagram according to the implementation environment shown in an exemplary embodiment.With reference to Fig. 1, the implementation environment
It can include 1201~120n of user equipment 110 and multiple transmission end user devices.Wherein, user equipment 110 and multiple transmissions
1201~120n of end user device is such as can be smart mobile phone, Intelligent bracelet, smartwatch and self-shooting bar.In Fig. 1,
User equipment 110 is illustrated with smart mobile phone, sends end user device 1201,1202 and 120n respectively with Intelligent bracelet, intelligence
Camera and computer are illustrated.
Fig. 2 is according to a kind of flow chart of method for data transmission shown in an exemplary embodiment, the method
For in user equipment 110, as shown in Fig. 2, the described method comprises the following steps.
In step s 11, the first modulated signal sent respectively by multiple transmission 1201~120n of end user device is received,
Each first modulated signal is modulated first carrier for corresponding transmission end user device the signal of generation, different transmitting terminals
The corresponding first carrier of user equipment is the mutually different ultrasonic wave of frequency.
First carrier can be modulated using the signal of data to be transmitted as modulated signal by sending end user device, and generation adds
The first modulated signal of data to be transmitted is loaded with, and first modulated signal is sent.Specifically, end user device is sent
In can be provided with ultrasonic transmitter, the first modulated signal for being loaded with data to be transmitted is sent.User equipment 110
First modulated signal can be received by ultrasonic receiver.
For example, user equipment 110 can be opened in the case where receiving the instruction for opening ultrasound signal receipt function
The function of received ultrasonic signal can also periodically turn on received ultrasonic signal according to the preset time cycle
Function.Fig. 3 is according to the surface chart for asking whether to open received ultrasonic signal shown in an exemplary embodiment.User sets
Standby 110 for example can be in the case where detecting ultrasonic signal, and what pop-up was as shown in Figure 3 in interface asks whether that unlatching connects
The button of the prompting of ultrasonic signal function is received, user can open the function of received ultrasonic signal by key mode.
Specifically, when user equipment 110 receives the first modulated letter of multiple transmission end user devices 1201~120n transmissions
Number when, the range of frequency that the ultrasonic receiver that sets in user equipment 110 is received can cover multiple transmission end subscribers
Frequency transmitted by 1201~120n of ultrasonic transmitter of equipment.In this way, multiple transmission end user devices 1201~120n hairs
The ultrasonic wave sent can be received, and handled by user equipment 110.
For example, 1201~120n of multiple transmission end user devices includes Intelligent bracelet 1201, intelligent video camera head 1202 and electricity
Brain 1203, send end user device 1201,1202 and 1203 distinguish transmission frequency be 20KHz, 40KHz and 80KHz first
Adjust signal.The data to be sent in Intelligent bracelet 1201 are loaded with by Intelligent bracelet 1201 in the first modulated signal of 20KHz
(for example, exercise data).Institute in intelligent video camera head 1202 is loaded with by intelligent video camera head 1202 in the first modulated signal of 40KHz
The data to be sent (for example, monitor video).Institute in computer 1203 is loaded with by computer 1203 in the first modulated signal of 80KHz
The data to be sent (for example, picture file).Ultrasonic receiver can be provided in user equipment 110, it being capable of receives frequency
Ultrasonic signal for 20KHz, 40KHz and 80KHz.It is set respectively by transmission end subscriber in this way, user equipment 110 can just receive
Standby 1201,1202 and 1203 signals for being loaded with pending data sent.
In step s 12, multiple the first received modulated signals are demodulated.
After receiving and being loaded with the first modulated signal of data to be transmitted, user equipment 110 can be set by inside
The software demodulation put goes out useful information (that is, the data to be transmitted loaded).
According to above technical scheme, according to user equipment can receive it is that multiple transmission end user devices are sent, with difference
The ultrasonic wave of frequency is the modulated signal of carrier wave and is demodulated, and is connected so as to be established simultaneously with multiple transmission end user devices
It connects, while receives the data that multiple transmission end user devices are sent.Therefore, the method for data transmission that the disclosure provides adds
Fast data transmission bauds, has saved data transmission period.
Alternatively it is also possible in advance bind multiple transmission 1201~120n of end user device with user equipment 110,

Ultrasonic wave.
With step S11 similarly, sending end user device 120 can be adjusted using the facility information of itself as modulated signal
First carrier processed, generation are loaded with the first modulated signal of facility information, and first modulated signal is sent.Wherein,
The facility information is specific for multiple transmission 1201~120n of end user device to be identified one by one for user equipment 110
Information.For example, facility information can be " bracelet one ", " bracelet two " " camera one ", " camera two " etc..
In step S14, multiple the first received matched signals are demodulated, obtain the facility information.
In step S15, solicited message is generated, the solicited message is for asking the facility information and corresponding
The frequency for sending the first carrier of end user device is associated.
Multiple transmission end user devices that user equipment 110 obtains the frequency of the ultrasonic signal received and demodulation
After the facility information association of 1201~120n, just binding relationship is established with multiple transmission 1201~120n of end user device.
If receiving the ultrasonic signal of identical frequency next time, the ultrasonic signal that user equipment 110 is thought to receive be and its
What the reception end user device associated by frequency was sent, so as to which the facility information of the ultrasonic signal received is fed back to
User, it is which sends the signal that end user device is sent to understand user.Fig. 5 is according to the life shown in an exemplary embodiment
Into the surface chart of solicited message.
In step s 16, instruction is being received by the first of the facility information and corresponding transmission end user device
In the case of the associated instructions that the frequency of carrier wave is associated, by the facility information and corresponding transmission end user device
The frequency of first carrier is associated.
In surface chart shown in Fig. 5, user pushes button "Yes", that is, has sent instruction to user equipment 110 and incite somebody to action
The associated instructions that the frequency of the facility information and the first carrier of corresponding transmission end user device is associated.At this point,
" bracelet one " can be associated storage by user equipment 110 with corresponding receives frequency.
Wherein, the step of of being demodulated to multiple the first received modulated signals (step S12) includes step
S121.In step S121, only first modulated signal with associated frequency received is demodulated.
After step S16, when receiving a ultrasonic signal, user equipment 110 can be with the information of calling stored
It is compared, judges whether the frequency of the ultrasonic signal received has been carried out being associated with.In the embodiment, user equipment
110 are only demodulated the ultrasonic signal of associated frequency.In this way, user can not only be made to understand received signal
Which comes from and sends end user device, and the ultrasonic signal received can be solved again after screening
It adjusts, improves the safety of data receiver.
