Specific embodiment
In order to make those skilled in the art better understand the technical solutions in the application, below in conjunction with the application reality
The attached drawing in example is applied, the technical scheme in the embodiment of the application is clearly and completely described, it is clear that described implementation
Example is merely a part but not all of the embodiments of the present application.Based on the embodiment in the application, this field is common
The application protection all should belong in technical staff's every other embodiment obtained without creative efforts
Range.
In view of the problems of existing means of payment, in view of terminal is when payment in this example, by same
When send lightwave signal and acoustic signals, at receiving end (or payment equipment end) according to receiving lightwave signal and acoustic signals
Time, determine terminal distance payment equipment end distance, determine whether to meet preset payment distance, if it is satisfied,
Payment data is then obtained from lightwave signal, if being unsatisfactory for preset payment distance, does not trigger delivery operation.By this
Mode, so that it may realize accurate ranging, and payment process is more convenient, accidentally paying occurs in the people for being also not easy to occur except range
The case where.
Based on this, a kind of distance measuring method is provided in this example, and the distance measuring method is mutually tied with lightwave data transmission
Close the method for payment for completing payment.Ranging is carried out by the transmission time difference of light wave and sound wave, is based on signal compared to existing
Intensity ranging scheme (such as: based on the ranging of bluetooth intensity, be based on intensity of acoustic wave ranging), by light wave and with the transmission of sound wave
Time difference ranging, available more stable distance measurement result may be implemented to pass through the flexible accurate control of payment range
Lightwave signal (for example, Bluetooth signal) transmits payment data, and it is low also to solve the problems, such as that sound wave pays existing transmission rate.
It is illustrated for using Bluetooth signal as lightwave signal, as shown in Figure 1, utilizing payment terminal (such as: mobile phone)
Existing bluetooth module and loudspeaker module simultaneous transmission short signal are (that is, Bluetooth broadcast channel short packages and sound wave pulse
Signal)；It pays equipment end and is receiving Bluetooth signal and when acoustic signals, when measuring the arrival of Bluetooth signal and acoustic signals
Between, according to the arrival time of Bluetooth signal and acoustic signals, determine payment terminal to the distance for paying equipment end.
As shown in Fig. 2, specifically, why payment terminal can be determined to payment machine according to Bluetooth signal and acoustic signals
Distance between tool is because the velocity of sound (340m/s) is well below the distance between the light velocity (3e8m/s), payment terminal to payment equipment
It can be approximated to be 340*dT.It is therefore unrelated with signal strength by being then based on transmission time difference ranging, it also would not be by people
The influence of body and environment to sound wave and lightwave signal intensity, so as to obtain than being based solely on Bluetooth signal ranging, Huo Zhedan
The solely distance measurement result more accurate based on acoustic signals ranging.
In this example, acoustic signals do not play the role of transmitting payment data, and are only to transmit for the short of ranging
When timing signal.In view of for acoustic signals, simple reception signal peak time judgement will receive ambient noise
It influences, therefore, it is necessary to control the arrival time of the signal to reach the ranging that the precision within 50us is able to achieve precision just as 1-2cm
Precision a, if only acoustic impluse in short-term is transmitted, when payment equipment microphone receiving end is difficult accurate reproduction arrival out
Between.
It, can be as shown in figure 3, believing in sound wave in order to improve the influence of timing signal precision and filtering environmental noise as far as possible
Number short-time pulse in transmission one end length be N (wherein, N can be 8 or the 16) pseudo-random sequence of position with value, in this way,
Receiving end can determine cross-correlation peak value by signal convolution, to obtain more accurate timing results.That is, passing through convolution correlation
Operation, in the correlation peak point time of the payment available signal in equipment end, to obtain more stable audio timing signal.
Sound wave pulse signal is when choosing, it is contemplated that it is preferably selected the signal frequency range that human ear can't hear, specifically,
When realization, the sound wave pulse signal of the frequency range between 18kHz to 24kHz can choose, and can be according to the energy of loudspeaker
Power is transmitted in multiple channels.
In this example, in order to realize ranging, Bluetooth signal needs to be closed with acoustic signals in time difference signal ranging
Connection correspond to because acoustic signals are only used for timing ranging, not Portable device identify, it is therefore possible to use acoustic signals with
Machine frequency hopping design carries bluetooth equipment ID (such as: MAC Address) in the data packet of Bluetooth signal and sets with the payment terminal
The current frequency of standby corresponding acoustic signals.
Arrival time and the correspondence of bluetooth data packets can be obtained by bluetooth listening broadcast channel at payment equipment end
Acoustic signals arrival time.Due to acoustic signals can in multiple frequency signal transmissions, selected by accidental channel
It selects, the collision between multiple mobile phones can be avoided to the greatest extent.Further, because can be big according to the intensity of Bluetooth signal
Cause the distance for judging payment terminal, therefore, can filter out and be not required to by the distance of the payment terminal determined based on Bluetooth signal
Bluetooth to be processed and sound wave time difference distance measuring signal.
In view of emitting core used by lightwave signal and transmitting acoustic signals when actually realizing, in payment terminal
Piece is different, will lead to actual signal transmission time and changes.As shown in Figure 1, if Bluetooth signal and acoustic signals are same
When issue, due to factors such as time delay of signal processor and operating system in different payment terminals, when actual signal transmits
Between from payment SDK call transmission application interface time may exist it is different, so also just will affect pay equipment end signal
The calculating of time difference.
For this purpose, the device model of payment terminal can be determined first, then the device model is calibrated, specifically, can
With by the off-line test to known distance, when calibrating the transmitting terminal acoustic signals as caused by equipment compatibility and Bluetooth signal
Between it is poor, and by the time difference be included in bluetooth data packets in, for pay equipment end group in the event difference carry out the time difference
Amendment.
In this example, acoustic signals are combined and lightwave signal carries out joint ranging, more accurately ranging can be carried out,
For example, range error can be limited between 5cm-10cm, it, can if applying the distance measuring method in payment scene
Payment range is accurately controlled with realizing.For example, in the scene of payment channel, can set payment fence distance as
Channel width (such as: 80cm), to reach accurate controllable payment range setting.That is, using acoustic signals and lightwave signal into
The ranging of row time difference may be implemented the ranging of stable and accurate payment terminal to payment equipment, flexibly may be used so as to reach
The payment distance of control or the control of payment fence, such as: it can be set to 20cm, 1m, 2m etc..
It is worth noting that, above-mentioned is the explanation carried out using Bluetooth signal as lightwave signal, when actually realizing,
The above-mentioned lightwave signal transmitted for ranging and data can also be Zigbee signal, WIFI signal etc., above-mentioned payment terminal
It can be other mobile devices, for example, wearable device, automobile, tablet computer etc..The application is not construed as limiting this,

Because chip used by different mobile phones is different, result in this way acoustic signals and lightwave signal transmission when
It waits, can there is certain time delay, for this purpose, can determine time delay present in each terminal device (that is, signal time is poor), it can
Carrying signal time difference in lightwave signal, in this way for receiving end, after getting lightwave signal, Ke Yicong
Extracting that signal time is poor in lightwave signal, the distance determined can be adjusted by being then based on signal time difference, thus
So that ranging is more accurate.That is, determining the distance of target object according to first time and second time, may include:
S1: it is poor to obtain the signal time carried in the lightwave signal；
S2: it is poor according to the signal time, the first time and second time are modified, after obtaining amendment
