Preferred embodiment
Current existing facility environment, generally have the communication equipment such as mobile phone, and mobile phone has loud speaker certainly, and intelligent appliance equipment all can have a microphone, therefore, the present invention based on prior art these thinking, it is contemplated that to select audible sound ripple also and above-mentioned hardware environment to access WiFi network.
Existing information of acoustic wave transmission, a kind of usual method be by by modulates information on the sound wave of certain frequency, take over party is by obtaining useful information to reception data demodulates, and another conventional method is analyzed in original time domain the data received, thus obtains useful data.
Current modulating data and time domain analysis shortcoming have three:
1) accuracy rate is low: according to the frequency spectrum speciality of voice signal, and audible sound ripple (20 20kHz) is one and is very easy to be subject to external interference, thus causes being configured to power very low. But, the embodiment of the present invention by time-domain signal is converted to frequency domain signal just can evade falling this problem.
2) cost height: prior art often will configure modulates information in supersonic band if it is desired to improve accuracy rate, although the low problem of accuracy rate can be solved like this, but what bring is the significantly increase of cost, and this is unrealistic often in family expenses.
3) configuration speed is slow: tradition sound wave configuration method is because of the speciality of its sound wave in time domain, and it is limited for transmitting quantity of information, can cause like this configuring overlong time. But, time-domain information is converted into frequency information by the embodiment of the present invention, by setting the judgement of frequency, it is possible to obtain valid data very fast.
The present embodiment is for above-mentioned thinking, it provides a kind of method accessing WiFi network. In embodiments of the present invention, with the intelligent equipment (such as mobile phone etc.) of loud speaker by digital to analog converter (Digitaltoanalogconverter, referred to as DAC) outwardly send a sound signal (sinusoidal wave, such as 100Hz) in loud speaker Hz-KHz. WIFI access device is by analog to digital converter (AnalogtoDigitalConverter, referred to as ADC) this sound signal of sampling, and the frequency domain data of sound signal is calculated by FFT, if this calculates data peaks is the 100Hz sent, data bit is judged as 1, illustrate that data now are available data, otherwise it is 0, without these data.
Transmitting procedure flow process for data can be as shown in Figure 6, in the process of transmission, 8 data bit are one group, form a data set, transmitting procedure is data set burst data transmission, and wherein commencing signal and end signal are also that the data set taking 8 data bit carries out transmitting, and its structure is illustrated as shown in Figure 7, in the drawings, commencing signal is not shown and terminates the physical length of signal. When realizing, each data bit interval 5ms, is furnished with a synchronous head (such as 0x55) before often organizing data. When configuration starts, intelligence equipment sends a commencing signal (such as 0x5A), after WIFI access device finds this commencing signal, enters data receive mode: often find a synchronous head, receive the sequential of a data bit with 5ms, altogether receive 8 data bit. Intelligence equipment sends and terminates signal (such as 0xAA) when finished. Now, WIFI access device networked required for data. The workflow of said process is as shown in Figure 8.
The embodiment of the present invention is by the judgement to certain frequency on audible sound ripple signal frequency domain, the data needed can be obtained very fast, simultaneously, because single-point frequency is in the singularity of a living environment, can effectively shield external interference, serve the effect of digital filtering, thus significantly improve the success ratio of configuration process. For the problem of data integrity, it is necessary to the particular data frame format provided by the present embodiment ensures.By the embodiment of the present invention, the signal analysis in frequency adds that the setting of particular data frame can significantly improve the speed in whole configuration process, immunity from interference and reliability.
Although being example object, having disclosed the preferred embodiments of the present invention, it is also possible for those skilled in the art will recognize various improvement, increase and replacement, and therefore, the scope of the present invention should be not limited to above-described embodiment.
