Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
As shown in Figure 1, in one embodiment, a kind of method that wireless monitoring equipment logs in wireless network is provided, it should
Method can be applied to establish the terminal of wireless communication with wireless monitoring equipment, and terminal can control wireless monitoring equipment, simultaneously
The monitoring picture that display wireless monitoring equipment transmits, these terminals include but not limited to the portable of AF playing function
Computer, personal digital assistant, tablet computer, smart mobile phone etc..This method comprises the following steps：
Step 101, terminal obtains network identity and network cipher.
In the present embodiment, network identity (SSID, service set) and network cipher (PASSWORD) are that wireless monitor is set
The standby network information for logging on to wireless network needs.Network identity and network cipher separately include at least one character.For example, net
Network mark and network cipher can be Route Distinguisher and routing login password under wireless router respectively.Terminal and wireless monitor
Equipment is under same wireless network, and terminal could be established with wireless monitoring equipment and be wirelessly communicated, and terminal obtains wireless monitor and sets
The network identity and cipher mark of the standby wireless network that will be logged in.
Step 102, network identity and network cipher are mapped as corresponding frequency of sound wave by terminal, and are given birth to according to frequency of sound wave
At audio data.
In the present embodiment, character, the word that terminal will include in network identity and network cipher are indicated by frequency of sound wave
Symbol is converted to corresponding frequency of sound wave, further, audio data is generated according to frequency of sound wave, for example, terminal is to by a string
Numerical character " 123 " is sent to wireless monitoring equipment, can the character " 1 ", " 2 " and " 3 " in " 123 " be first respectively converted into correspondence
10HZ, 20HZ and 30HZ frequency of sound wave, then according to the frequency of sound wave of 10HZ, 20HZ and 30HZ generate audio data.
In one embodiment, according to nyquist sampling theorem, in the transfer process for carrying out analog/digital signal,
If sample frequency is more than 2 times that send signal frequency, the signal after sampling could completely retain the letter in original signal
Breath.Network identity and network cipher are mapped as corresponding frequency of sound wave and similarly follow this principle by terminal, for example, wireless prison
The frequency of sound wave for controlling equipment sampling is 8000HZ, in order to ensure that wireless monitoring equipment can accurately identify the frequency of sound wave of terminal transmission
Corresponding character, then network identity and the frequency of sound wave highest of network cipher mapping are no more than 4000HZ (8000HZ/2).
Step 103, audio data is converted to voice signal and sent by terminal.
In the present embodiment, frequency of sound wave is played out by voice signal, specifically, the sound card in terminal is by audio data
It is converted to voice signal and is played out by included loud speaker, since voice signal corresponds to network identity and network is close
Code, wireless monitoring equipment is anti-by network identity and network cipher lane in order to prevent, should first believe the corresponding sound of network identity
It number plays out, then plays the corresponding voice signal of network cipher again.
Voice signal can be interfered in communication process by ambient noise, therefore be needed during sending voice signal
Pay attention to problems with：
(1) there should be enough discriminations between frequency of sound wave, that is, when should have enough between the voice signal sent
Between be spaced, by test, it is preferred that time interval be 100 milliseconds.As shown in Fig. 2, being one section of amplified display of voice signal
Scheme, the line of the different density degree in figure represents different frequency of sound wave, has fixed width between different frequency of sound wave, should
Width is the time interval sent between voice signal.
(2) since voice signal has certain loss and superimposed noise in the air so that wireless monitoring equipment receives
Voice signal outline is less than the voice signal that terminal is sent.As shown in figure 3, for one section of voice signal pair in the voice signal of transmission
The oscillogram answered is apparent that ambient noise is influenced caused by voice signal from figure.Therefore, sending voice signal needs
(SendTime) just can guarantee that wireless monitoring equipment can be analyzed receiving voice signal for a period of time for the transmission to be stablized,
Preferential after tested, SendTime takes 50 milliseconds.
(3) in order to avoid there is voice signal aliasing, during sending voice signal, network identity has been sent
It is needed after waiting for a period of time after corresponding voice signal, just sends the corresponding voice signal of network cipher.One section of the waiting
Time is transmission time interval (SendInterTime), and after tested preferably, SendInterTime is 1 second.
Step 104, wireless monitoring equipment receives voice signal, is decoded to obtain network identity and net to voice signal
Network password.
Step 105, wireless monitoring equipment logs on to corresponding wireless network according to network identity and network cipher.
The voice signal that terminal is sent is propagated in air, and the microphone of wireless monitoring equipment collects terminal and sends over
Voice signal after, voice signal be converted to be decoded after audio data get corresponding frequency of sound wave, according to sound wave
For frequency acquisition to network identity and network cipher, wireless monitoring equipment can log on to correspondence by network identity and network cipher
Wireless network.Terminal scans under the wireless network arrives the wireless monitoring equipment so that the wireless monitoring equipment is registered automatically
Into terminal so that terminal establishes the wireless communication between wireless monitoring equipment.
The method that above-mentioned wireless monitoring equipment logs in wireless network, can by terminal by network identity and network cipher with
Voice signal is sent to wireless monitoring equipment, and wireless monitoring equipment can automatically log into corresponding nothing by receiving voice signal
In gauze network, the purpose of the terminal-pair wireless monitoring equipment plug and play automatic configuration network information is realized, is simplified to nothing
The operating process of line monitoring device network information configuration, thus, high wireless monitoring equipment logs on to the efficiency of wireless network, shortens
R&D cycle of wireless monitoring equipment, reduce R&D costs.
