Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, in one embodiment, provide a kind of method that wireless monitoring equipment logs in wireless network, the method can be applicable to the terminal setting up radio communication with wireless monitoring equipment, terminal can control wireless monitoring equipment and show the monitoring picture that wireless monitoring equipment transmits, and these terminals include but not limited to the portable computer, personal digital assistant, panel computer, smart mobile phone etc. of being with AF playing function.The method comprises the steps:
Step 101, terminal obtains network identity and network cipher.
In the present embodiment, network identity (SSID, service set) and network cipher (PASSWORD) are the network informations that wireless monitoring equipment signs in wireless network needs.Network identity and network cipher comprise at least one character respectively.Such as, network identity and network cipher can be Route Distinguisher under wireless router and route login password respectively.Under terminal and wireless monitoring equipment are in same wireless network, terminal could set up radio communication with wireless monitoring equipment, and terminal obtains network identity and the cipher mark of the wireless network that wireless monitoring equipment will log in.
Step 102, network identity and network cipher are mapped as corresponding frequency of sound wave by terminal, and generate voice data according to frequency of sound wave.
In the present embodiment, character is represented by frequency of sound wave, the character conversion comprised in network identity and network cipher is corresponding frequency of sound wave by terminal, further, voice data is generated according to frequency of sound wave, such as, terminal is to send to wireless monitoring equipment by string number character " 123 ", first the character " 1 " in " 123 ", " 2 " and " 3 " can be converted to respectively the frequency of sound wave of corresponding 10HZ, 20HZ and 30HZ, then generate voice data according to the frequency of sound wave of 10HZ, 20HZ and 30HZ.
In one embodiment, according to nyquist sampling theorem, in the transfer process of carrying out analog/digital signal, if when sample frequency is greater than 2 times that send signal frequency, the signal after sampling intactly could retain the information in primary signal.Network identity and network cipher are mapped as corresponding frequency of sound wave and follow this principle too by terminal, such as, the frequency of sound wave of wireless monitoring equipment sampling is 8000HZ, in order to ensure the character that the frequency of sound wave of wireless monitoring equipment energy accurate identification terminal transmission is corresponding, then the frequency of sound wave of network identity and network cipher mapping is the highest can not more than 4000HZ (8000HZ/2).
Step 103, voice data is converted to voice signal and sends by terminal.
In the present embodiment, frequency of sound wave is played out by voice signal, concrete, voice data is converted to voice signal and is play by the loud speaker carried by the sound card in terminal, because voice signal correspond to network identity and network cipher, in order to prevent wireless monitoring equipment from network identity and network cipher are done anti-, voice signal that should be first corresponding to network identity is play, and then the voice signal that playing network codon pair is answered.
Voice signal can be subject to the interference of ambient noise in communication process, therefore in the process sending voice signal, should be noted that following problem:
(1) should have enough discriminations between frequency of sound wave, should have time enough interval between the voice signal namely sent, through test, preferably, the time interval is 100 milliseconds.As shown in Figure 2, be the display figure after one section of voice signal amplifies, the line of the different density degree in figure represents different frequency of sound wave, has fixing width between different frequency of sound wave, and this width is the time interval sent between voice signal.
(2) because voice signal has certain loss and superimposed noise in the air, wireless monitoring equipment reception voice signal is made will to be slightly less than the voice signal of terminal transmission.As shown in Figure 3, be the oscillogram that one section of voice signal in the voice signal of transmission is corresponding, the impact seeing that ambient noise causes voice signal can be known from figure.Therefore, sending voice signal needs stable transmission a period of time (SendTime) guarantee wireless monitoring equipment can to receiving voice signal analysis, and preferential after tested, SendTime gets 50 milliseconds.
(3) in order to avoid there is voice signal aliasing, in the process sending voice signal, after needing after sending voice signal corresponding to network identity to wait for a period of time, the voice signal that just transmission network cipher is corresponding.A period of time of this wait is transmission time interval (SendInterTime), and after tested preferably, SendInterTime is 1 second.
Step 104, wireless monitoring equipment receives voice signal, carries out decoding obtain network identity and network cipher to voice signal.
Step 105, wireless monitoring equipment signs in corresponding wireless network according to network identity and network cipher.
The voice signal that terminal sends is propagated in atmosphere, after the microphone of wireless monitoring equipment collects the voice signal that terminal sends over, carrying out after voice signal being converted to voice data decodes gets corresponding frequency of sound wave, get network identity and network cipher according to frequency of sound wave, wireless monitoring equipment can sign in corresponding wireless network by network identity and network cipher.Terminal scans this wireless monitoring equipment under this wireless network, makes this wireless monitoring equipment be automatically registered in terminal, makes terminal establish radio communication between wireless monitoring equipment.
