Detailed Description
In order to make the objects, technical solutions and technical effects of the present invention more clear, embodiments of the present invention are further described in detail below with reference to the accompanying drawings. It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, belong to the scope of the present invention.
Fig. 1 is a flowchart of a first embodiment of a communication method according to the present invention. Referring to fig. 1, the communication method of the present embodiment includes the following steps: step S11: the first terminal emits information of a first frequency capable of receiving sound waves by modulating and loading information on a first group of sound waves with at least two sections of frequencies.
In this embodiment, the first terminal acts as a sender or a sender terminal, and correspondingly, the second terminal acts as a receiver or a receiver terminal. The first terminal and the second terminal mentioned throughout the present invention are exemplified by a smart phone, and certainly not limited to the smart phone, and may be any terminal having a sound wave transmitting and receiving function, including a notebook computer, a portable communication device, a PDA (personal digital assistant or tablet computer), an audio access control device, an audio identification and transaction payment terminal Key, and the like. Based on the above, the communication method of the invention can be suitable for access card swiping, on-the-spot transaction payment, identity identification and authentication and the like.
It should be noted that data encoding is also required before the information of the first frequency is modulated. The modulated information of the frequency of the first sound wave is embodied as a set of coded modulation data, and therefore, the set of coded modulation data must be subjected to digital-to-analog conversion to obtain corresponding analog information, and then the analog information is loaded on the first set of sound waves to be sequentially transmitted, although the first set of sound waves may also be transmitted simultaneously.
The first group of sound waves preferably has three-stage sound wave frequencies and is non-second harmonic frequencies. Of course, in other embodiments, persons skilled in the art may set the first group of sound waves to have other numbers of segments of frequencies, and the invention is not limited in this regard.
After the first set of sound waves is emitted, the first terminal turns on its own recording device, such as a microphone, and prepares to receive information fed back by the second terminal in the form of sound waves.
Step S12: the second terminal records the first group of sound waves sent by the first terminal and demodulates the first group of sound waves by adopting a second frequency which is specified in advance.
The second terminal sequentially records a first group of sound waves sent by the first terminal through a recording device of the second terminal, such as a microphone, then performs analog-to-digital conversion on the received first group of sound waves, and then demodulates and decodes the first group of sound waves after the analog-to-digital conversion.
Demodulation is the reverse process of modulation, namely information of a loaded first frequency is obtained from a first group of sound waves with three different frequencies (high frequencies) without distortion, and the demodulation frequency must be selected during demodulation.
Step S13: and judging whether the second terminal demodulates to obtain the information of the first frequency.
If the second terminal does not demodulate the information of the first frequency, which indicates that the second terminal cannot demodulate the first group of sound waves using the second frequency, that is, the second terminal cannot communicate with the first terminal at the second frequency, step S14 is executed. Conversely, if the second terminal demodulates the information of the first frequency, which indicates that the second terminal can demodulate the first group of sound waves by using the second frequency, that is, the second terminal can communicate with the first terminal by using the second frequency, step S15 is executed.
Step S14: the first terminal emits information modulation loaded on the first sound wave frequency on the second group of sound waves.
The second group of sound waves have at least two sections of sound wave frequencies different from those of the first group of sound waves, and the number of the sections of the sound wave frequencies of the second group of sound waves can be the same as that of the first group of sound waves or can be different from that of the first group of sound waves. The second group of sound waves of the present embodiment is the upper level of the at least two sound wave frequencies different from the first group of sound waves, that is, as long as the second terminal cannot demodulate the information of the first sound wave frequency through the second frequency, the step S11 is repeated, and the first terminal loads the information of the first sound wave frequency to the sound waves of other frequencies and emits the information until the step S13 is followed, and then the step S14 is not executed, but the step S15 is executed.
Step S15: the first terminal and the second terminal communicate with each other through the first frequency and the second frequency.
Based on the above, it can be seen that in the embodiment, through one or more times of sound wave communication with different frequencies between the first terminal as the sender and the second terminal as the receiver, until the second terminal can demodulate the first group of sound waves sent by the first terminal by using the second frequency specified in advance, information of the first frequency, which is loaded by the first group of sound waves and can receive the sound waves, of the first terminal is obtained, and then the second frequency and the first frequency are used as sound wave frequencies for communication between the two parties, so that the sound wave frequencies between the communication terminals can be autonomously adapted, the compatibility between the communication terminals is improved, and further the success rate of data transmission between the communication terminals is improved.
Fig. 2 is a flowchart of a communication method according to a second embodiment of the present invention. Referring to fig. 2, based on the description of the first embodiment, the communication method of the embodiment includes the following steps:
step S21: the first terminal modulates and loads information of a first model of the first terminal and a first frequency capable of receiving sound waves to a first group of sound waves with at least two sections of frequencies to emit the sound waves.
Step S22: the second terminal records the first group of sound waves sent by the first terminal and demodulates the first group of sound waves by adopting a second frequency which is specified in advance.
In this embodiment, the first terminal preferably detects whether it is adapted to another terminal before the current communication, that is, the first terminal detects whether the first model of the first terminal is in a mapping relationship with models of other terminals, and whether the frequency of the sound wave that the first terminal can receive is in a mapping relationship with other sound wave frequencies. If the mapping relationship exists, it indicates that the first terminal has been previously adapted, and in this case, it is preferable to select the adapted sound wave frequency as the demodulation frequency, that is, the second frequency demodulates the first group of sound waves emitted by the first terminal.
Step S23: and judging whether the second terminal demodulates to obtain the information of the first model and the first frequency.
If the second terminal does not demodulate the information of the first model and the first frequency, which indicates that the second terminal cannot demodulate the first set of sound waves using the second frequency, i.e. the second terminal cannot communicate with the first terminal at the second frequency, step S24 is executed. Conversely, if the second terminal demodulates the information of the first model and the first frequency, which indicates that the second terminal can demodulate the first set of sound waves using the second frequency, i.e., the second terminal can communicate with the first terminal using the second frequency, step S25 is executed.
Step S24: the first terminal emits the information modulation of the first model and the first sound wave frequency loaded on the second group of sound waves.
Step S25: and the second terminal modulates and loads the information of the second model and the second frequency of the second terminal on the sound wave with the first frequency to emit the information.
Step S26: the first terminal and the second terminal communicate with each other through the first frequency and the second frequency.
The step further records the mapping relation between the second model and the first model as well as between the first model and the second frequency as well as between the first frequency, so that the first terminal and the second terminal can directly adapt the sound wave frequency according to the mapping relation during the later communication. For this purpose, the embodiment preferably records the mapping relationship in both the first terminal and the second terminal.
