Fig. 3 is a flowchart illustrating a method for distributing a network according to an exemplary embodiment, where in the embodiment illustrated in fig. 3, the first terminal is a mobile phone, and the second terminal is a camera, for example, to describe, that is, in the embodiment illustrated in fig. 3, a network distribution method provided by the present disclosure is described by taking a mobile phone as a camera, as illustrated in fig. 3, the method includes the following steps:
in step S301, the mobile phone acquires network configuration information.
The network configuration information may include network access information and user information associated with a terminal (i.e., a second terminal) to be configured with a network, specifically, the network access information may include a router ID and a password of a network to be connected to the camera, the user information may include encrypted information of a user name of a user who inputs the network configuration information, and in addition, the user information may further include information such as encrypted information of an area where the user is located, fig. 4 is a scene interaction diagram illustrating how a mobile phone performs network distribution for a smart camera according to an exemplary embodiment, as shown in fig. 4, in a specific network distribution scene, the camera is initialized first, the user may input the router ID, the password and other network configuration information in an interface of a mobile phone application program, and then, a mobile phone terminal may combine the network configuration information input by the user into a character string in a specific format, so as to generate a playable audio file based on the character string.
For example, the internal data protocol format may be b = xxxxx & s = xxxxx & p = xxxxx & r = xxxxx, where s and p fields are used to store character strings corresponding to router IDs and passwords, b field is used to store a character string corresponding to encryption information of a user name of a user who inputs the network configuration information, and r field is used to store a character string corresponding to encryption information of an area where the user who inputs the network configuration information is located, so that the network configuration information input by the user may be combined into a character string in a specific format, which is described in the above example only by way of example, and the disclosure is not limited thereto.
In step S302, the mobile phone performs AES encryption processing on the network configuration information to obtain network configuration encryption information.
In this step, in order to improve the security of data communication, the network configuration information to be transmitted may be encrypted, and the mobile phone may perform AES encryption on a character string of a specific format combined based on the network configuration information.
Any AES encryption algorithm such as AES128, AES256, AES192, etc. may be used to encrypt the character string, and the specific encryption process may refer to descriptions in related documents, which is not limited in this disclosure.
In step S303, a check code and a forward error correction code are added to the network configuration encryption information to obtain a network configuration data frame.
In order to improve the accuracy and the reliability of communication data transmission, a Check code and a forward error correction code may be added to the data to be transmitted, where the Check code may be a CRC (Cyclic Redundancy Check) 32 Check code, and the forward error correction code may be an FEC forward error correction code.
In this step, the mobile phone may generate a Cyclic Redundancy Check (CRC) 32 check code for the network configuration encryption information through byte exclusive-or calculation, and generate the forward error correction code for the network configuration encryption information through a Forward Error Correction (FEC) algorithm; and then combining the network configuration encryption information, the CRC32 check code and the FEC forward error correction code to obtain a network configuration data frame.
In step S304, the mobile phone performs high-frequency GMSK code modulation on the network configuration data frame to obtain the first encoded data, and performs low-frequency GMSK code modulation on the network configuration data frame to obtain the second encoded data.
In order to improve the detection rate of data, the network configuration data frame can be encoded by adopting two frequencies (namely high frequency and low frequency), so that after a camera end receives sound, the network configuration information can be obtained by decoding data of one frequency, the detection rate of the network configuration information is improved, and the efficiency of a distribution network and the success rate of the distribution network are further improved.
In this step, a preset high-frequency center frequency and a preset low-frequency center frequency may be obtained; then, according to the preset high-frequency central frequency, high-frequency GMSK coding modulation is carried out on the network configuration data frame to obtain first coding data; and performing low-frequency GMSK coding modulation on the network configuration data frame according to the preset low-frequency central frequency to obtain the second coding data.
For example, the preset high frequency center frequency may be 7200HZ, and the preset low frequency center frequency may be 3200HZ, which are only examples, and in practical applications, the high frequency center frequency and the low frequency center frequency may be set arbitrarily according to specific requirements.
In step S305, the mobile phone determines pulse code modulation PCM acoustic data from the first encoded data and the second encoded data.
In this step, the mobile phone may generate the high frequency PCM data by the NCO according to a preset acoustic wave sampling rate from the first encoded data, generate the low frequency PCM data by the NCO according to the preset acoustic wave sampling rate from the second encoded data, and then superimpose the digital voice on the high frequency PCM data and the low frequency PCM data to obtain the PCM acoustic wave data.
The preset acoustic wave sampling rate can also be set according to actual requirements, and for example, can be set to 32K.
In step S306, after writing the PCM sound wave data into a preset file, the mobile phone generates a WAV audio file by adding WAV file format header data to the PCM sound wave data, and plays the WAV audio file.
In order to enable the mobile phone end to normally play the generated PCM sound wave data, the PCM sound wave data also needs to be converted into a playable audio file in a preset audio format, for example, the preset audio format may be any audio format such as WAV and mp3, and in consideration of the fact that the audio file in the WAV format is not distorted, in order to further ensure the accuracy of data transmission, in this embodiment, the mobile phone may convert the PCM sound wave data into the WAV audio file.
The WAV file format may be specifically set according to experience and a preset sound wave sampling rate when the PCM sound wave data is generated by the NCO, for example, the WAV file format may be set to a mono channel/32K sampling rate/16-bit wide, which is only an example here, and the disclosure does not limit this.
In step S307, the camera records the WAV audio file played by the mobile phone to obtain PCM sound wave data.
The PCM sound wave data is generated by the mobile phone after network configuration information is subjected to high-frequency and low-frequency GMSK coding modulation respectively.
In a possible implementation manner of this step, the camera may first create a ring buffer queue, and may start two threads, one thread may call a BSP interface of the camera to record, collect PCM sound wave data, and set a format of the PCM sound wave data to be monaural/32K sampling rate/16 bit wide, the recorded data is written into the ring buffer queue, and the other thread may loop to read the ring buffer data, and perform S308 to complete data demodulation.
In step S308, the camera performs GMSK demodulation on the PCM acoustic data to obtain a network configuration data frame.
As described above, the mobile phone encodes the network location information by using two frequencies, i.e. high frequency + low frequency, and considering that the decoding frequencies supported by different cameras may be different, in this step, the camera may demodulate by using any one of the following two methods:
in the first mode, the PCM sound wave data is subjected to GMSK demodulation according to a preset frequency supported by the camera to obtain the network configuration data frame, where the preset frequency includes a high frequency or a low frequency.
