With continued reference to FIG. 2, a flow 200 of one embodiment of a method for transmitting data in accordance with the present application is shown. The method for transmitting data of the embodiment comprises the following steps:
In this embodiment, the execution subject of the method for transmitting data (e.g., the server 105 shown in fig. 1) may acquire the target data from a computer or a terminal by wired connection or wireless connection. The target data may be payload data in which audio information to be transmitted is described.
In step 202, the target data is divided into data blocks having a first predetermined number of bytes.
In this embodiment, after the execution main body obtains the target data, the execution main body may divide the target data into data blocks having a first preset number of bytes. The number of bytes contained in the data block may be fixed or variable, and is not specifically limited in this application. Each data block comprises a set of data arranged consecutively together in the order of the target data.
After obtaining the data block, the execution subject may determine the first frame sequence from the data block. Specifically, the execution body may add a check code at the head or the tail of the data block, and a specific relationship exists between the check code added by the execution body and the corresponding data block, for example, the check code is obtained by the operation of adding, subtracting, multiplying and/or dividing data between the data blocks, and if a bit or bits of the data block are erroneous due to interference or the like, the specific relationship is destroyed. The data blocks to which the check code is added are combined into a first frame sequence. Wherein, the length of the check code is fixed or has a special mark.
The execution body may modulate the first sequence of frames into audio data after obtaining the first sequence of frames. In particular, the first frame sequence may be a baseband signal and the audio data may be a frequency band signal, which needs to be modulated for higher quality transmission. The modulation of the first frame sequence may be classified as amplitude modulation, frequency modulation, phase modulation. The first frame sequence may be modulated into audio data by adjusting the Amplitude and phase of the first frame sequence, for example, by a Quadrature Amplitude Modulation (QAM) method.
After obtaining the audio data, the execution main body may play the audio data through an audio playing device, such as a sound box, a radio, and the like.
With continued reference to fig. 3, a schematic diagram of one application scenario of a method for transmitting data according to the present application is shown. In the application scenario of fig. 3, a server 301 obtains target data W, and the server 301 divides the target data W into data blocks 302 having a first preset number of bytes, where the data blocks are denoted by a, B, C, D, …, I; the server 301 determines a first frame sequence 303 from the data blocks a, B, C, D, …, I, the first frame sequence 303 being denoted a, B, C, D, …, I. The server 301 modulates the first frame sequence 303 into audio data 304 and the audio data 304 is played by the audio playing device 305.
According to the embodiment, the target data is divided into the data blocks, so that the accuracy of data verification is improved, and a better information transmission effect is achieved.
With continued reference to fig. 4, a flow 400 of another embodiment of a method for transmitting data in accordance with the present application is shown. As shown in fig. 4, the method for transmitting data of the present embodiment may include the following steps:
At step 402, the target data is divided into data blocks having a first predetermined number of bytes.
The principle of step 401 and step 403 is similar to that of step 201 and step 203, and is not described here again.
Specifically, step 403 can be implemented by steps 4031 to 4032 as follows:
After the execution main body obtains the data blocks, a first check code corresponding to each data block can be calculated. Specifically, the Check code corresponding to each data block may be calculated by a Cyclic Redundancy Check (CRC). CRC is a calculation method for checking the accuracy of digital transmission over a communication link, and an agreed relationship between data bits and check bits is established by a certain mathematical operation, so that corresponding check bits can be calculated from the data bits, that is, a corresponding check code can be calculated for each data block according to the CRC32 algorithm in the present application.
After the execution main body obtains the first check code corresponding to each data block, each data block may be combined with the first check code corresponding to each data block to obtain a first frame sequence. The execution main body can place the first check code at the head part or the tail part of the corresponding data block, or at a certain position inside the data block, so that the data block and the corresponding first check code are combined to form a first frame sequence. The first frame sequence is obtained by combining a plurality of data frames, and each data frame is obtained by combining one data block and a corresponding first check code. The specific position of the first check code placed in the data block is not limited by the application.
In this embodiment, the first check code corresponding to each data block is calculated, and each data block and the corresponding first check code are combined to form the first frame sequence, so that the accuracy of the transmitted data can be more accurately judged.
Step 404 modulates the first sequence of frames into audio data.
The principle of step 404 is similar to that of step 204, and is not described here again.
Specifically, step 404 can be implemented by steps 4041 to 4042 as follows:
The execution subject, after obtaining the first frame sequence, may divide the first frame sequence into data groups having a second preset number of bits, for example, dividing every 4 bits into a group; and adjusting the bits in each data group into bits with preset phases and preset amplitudes, and modulating the bits to preset carriers to obtain audio data. Specifically, the execution subject may adjust the Amplitude and the phase of each group of data in the first frame sequence by a Quadrature Amplitude Modulation (QAM) method using a 16QAM modulator. And modulating each group of data after adjusting amplitude and phase onto a carrier by Orthogonal Frequency Division Multiplexing (OFDM), wherein the carrier can select the frequency of 2 KHz-12 KHz and the number of the subcarriers can be 8 in consideration of the characteristics of audio playing and receiving equipment, thereby obtaining audio data. OFDM is one type of multi-carrier modulation. The parallel transmission of high-speed serial data is realized through frequency division multiplexing, and the parallel transmission device has better multipath fading resistance and can support multi-user access.
The present embodiment can improve the accuracy of phase and amplitude adjustment for the first frame sequence by dividing the first frame sequence into data groups and adjusting the phase and amplitude for each data group.
Specifically, step 4042 may be implemented by steps 40421 to 40422 as follows:
Specifically, after the execution body divides every 6 bits in the first frame sequence into one data group, the 6 bits in each data group may be mapped to one state of a 64QAM constellation by a 64QAM modulator. State, refers to the unique 64 constellation points of a 64QAM constellation determined by 6 bits. For example, there is 2 from the 6 bits of a data set 100001 in the first frame sequence6Different permutation combinations, each of which may be mapped to a constellation point in a 64QAM constellation diagram, such that one of the first frame sequencesData set 100001 may determine 64 constellation points of a 64QAM constellation, where the 64 constellation points determined correspond to a unique state of a 64QAM constellation.
After obtaining the state of the preset constellation corresponding to each data group, the execution main body may modulate each state to a preset carrier to obtain audio data. Specifically, the execution main body may modulate data having a preset phase and amplitude corresponding to each state onto carriers of 2KHz to 12KHz through an OFDM technique, where the number of the carriers may be 8, and the carrier frequency and the number are not specifically limited in the present application.
In the embodiment, the bits in each data group are mapped into one state of the preset constellation diagram, so that a foundation can be laid for correctly demodulating data subsequently.
The principle of step 405 is similar to that of step 205, and is not described here again.
With further reference to fig. 5, as an implementation of the methods shown in the above-mentioned figures, the present application provides an embodiment of an apparatus for transmitting data, which corresponds to the method embodiment shown in fig. 2, and which is particularly applicable to various electronic devices.
As shown in fig. 5, the apparatus 500 for transmitting data of the present embodiment includes: a data acquisition unit 501, a data block division unit 502, a first frame sequence determination unit 503, a modulation unit 504, and an audio playback unit 505.
A data acquisition unit 501 configured to acquire target data.
A data block dividing unit 502 configured to divide the target data into data blocks having a first preset number of bytes.
A first frame sequence determining unit 503 configured to determine the first frame sequence based on the data blocks.
A modulation unit 504 configured to modulate the first sequence of frames into audio data.
An audio playing unit 505 configured to play audio data.
In some optional implementations of this embodiment, the first frame sequence determining unit 503 is further configured to: calculating a first check code corresponding to each data block; and combining each data block with the first check code corresponding to each data block to obtain a first frame sequence.
In some optional implementations of this embodiment, the modulation unit 504 is further configured to: dividing the first frame sequence into data groups having a second preset number of bits; and adjusting the bits in each data group into bits with preset phases and preset amplitudes, and modulating the bits to preset carriers to obtain audio data.
In some optional implementations of this embodiment, the modulation unit 504 is further configured to: mapping the bits in each data group into a state of a preset constellation diagram; and modulating each state to a preset carrier wave to obtain audio data.
It should be understood that units 501 to 505, respectively, recited in the apparatus 500 for transmitting data correspond to the respective steps in the method described with reference to fig. 2. Thus, the operations and features described above for the method for transmitting data are equally applicable to the apparatus 500 and the units included therein and will not be described again here.
With continued reference to FIG. 6, a flow 600 of one embodiment of a method for transmitting data in accordance with the present application is shown. The method for transmitting data of the embodiment comprises the following steps:
In this embodiment, the execution subject of the method for transmitting data (for example, the server 105 shown in fig. 1) may sample the audio data played from the audio playing device through a wired connection or a wireless connection. In particular, the execution body may sample audio data at a 32k sampling rate. The sampling rate is not specifically limited in this application. The sampling rate, i.e. the sampling frequency, refers to the number of times a sound sample is taken per second. The higher the sampling frequency is, the better the sound quality is, and the more real the sound is restored, but the more resources are occupied at the same time.
Step 602 demodulates the sampled audio data into a second frame sequence.
The audio data obtained by performing the body sampling is a frequency band signal overmodulating the phase and amplitude, and the frequency band signal needs to be demodulated into a second frame sequence, which can be obtained by demodulating the modulated frequency band signal through OFDM.
After obtaining the second frame sequence, the execution subject may determine the plurality of data blocks according to the second frame sequence and the first preset number. In particular, the execution body may divide the second frame sequence into a plurality of data blocks having a first preset number of bytes.
After the execution main body obtains the plurality of data blocks, the accuracy of the obtained plurality of data blocks can be verified, and after the verification is passed, the execution main body can directly combine the plurality of data blocks according to a preset arrangement sequence to obtain target data.
With continued reference to fig. 7, a schematic diagram of one application scenario of a method for transmitting data according to the present application is shown. In the application scenario of fig. 7, the server 701 samples the played audio data; the server 701 demodulates the sampled audio data V into a second frame sequence 702, where the second frame sequence 702 is composed of a ', a, B ', B, C ', C, D ', D, …, and I ', I; determining a plurality of data blocks 703 according to the second frame sequence and the first preset number, where the plurality of data blocks 703 may be denoted as a ', B ', C ', D ', …, I '; the server 701 determines the target data 704 from the plurality of data chunks a ', B ', C ', D ', …, I '.
According to the embodiment, the plurality of data blocks are determined according to the second frame sequence and the first preset number, so that the accuracy of data verification is improved, and a better information transmission effect is achieved.
With continued reference to fig. 8, a flow 800 of another embodiment of a method for transmitting data in accordance with the present application is shown. As shown in fig. 8, the method for transmitting data of the present embodiment may include the following steps:
The principle of steps 801 to 802 is similar to that of steps 601 to 602, and is not described here again.
Specifically, step 802 can be implemented by steps 8021 to 8023 as follows:
The execution body may divide the audio data into data groups having a second preset number of bits after the audio data is sampled. The audio data is effectively a sequence of frames that have been amplitude and phase modulated. The sequence of frames corresponding to the audio data is divided into data groups having a second predetermined number of bits. For example, when the target data is modulated, every 4 bits in the first frame sequence corresponding to the target data are divided into one data group, and then when the audio data is demodulated, every 4 bits in the frame sequence corresponding to the audio data are also divided into one data group.
The execution body may determine a state of a preset constellation corresponding to each data group after dividing the audio data into the data groups having the second preset number of bits. The state of the predetermined constellation is a mapping of possible combinations of data in each data set, each data combination being mapped to a constellation point in the predetermined constellation, and each constellation point representing a combination of phase and amplitude. According to the phase and amplitude of the data group with the second preset number of bits, the constellation point can be determined, according to the constellation point, the state of the preset constellation diagram can be determined, and according to the preset relation between the state of the preset constellation diagram and the second preset double bits, the second preset number of bits which are uniquely corresponding to the state of the preset constellation diagram can be determined.
Specifically, step 8022 can be implemented by the following step 80221:
Each data group in the audio data corresponds to a state of a preset constellation diagram. After dividing the audio data into data groups having a second preset number of bits, an execution entity of the preset constellation may determine the second preset number of bits mapped to each state of the preset constellation according to a mapping relationship between each data group and one state of the preset constellation, respectively. For example, three bits of 001, can uniquely determine the state of an 8QAM constellation. Three bits of 001, having 2 3Different permutation combinations, each mapping to a constellation point in an 8QAM constellation, 23Arranging and combining to form a state of the 8QAM constellation diagram, wherein the state and the corresponding mapping relation determined by the three bits 001 are unique, and after the execution main body obtains a state of the preset constellation diagram, if the state and 2 of the three bits 001 are the same3If the permutation and combination are matched, the data of the second preset number of bits corresponding to the state of the 8QAM constellation can be determined to be 001.
In this embodiment, the second preset number of bits corresponding to each state is determined according to each state of the preset constellation diagram, so that the sampled audio data can be accurately demodulated.
And after obtaining a second preset number of bits corresponding to each state of the preset constellation diagram, the execution main body arranges and combines the second preset number of bits according to a preset sequence to form a second frame sequence.
The present embodiment can accurately demodulate sampled audio data.
The principle of step 803 is similar to that of step 603, and is not described here again.
Specifically, step 803 can be implemented by the following step 8031:
After the execution main body obtains the second frame sequence, each frame in the second frame sequence may be divided into a data block having a first preset number of bytes and a first check code, so as to obtain a plurality of data blocks. Here, a cyclic redundancy check method is used to check the sampled audio data. Before audio data is sent, the execution main body calculates a first check code for the divided data blocks, attaches the first check code to the transmitted data blocks and sends the data blocks to the audio receiving equipment. After the audio receiving device receives the data, a second frame sequence is obtained through demodulation, the second frame sequence comprises a first check code carried by the transmitted data, and the execution main body can divide each frame of the second frame sequence to separate the payload data of each frame, namely the data blocks of the first preset number of bytes of each frame, from the first check code to obtain a plurality of data blocks with the first preset number of bytes.
The principle of step 804 is similar to that of step 604, and is not described here again.
Specifically, step 804 can be realized by steps 8041 to 8042 as follows:
Specifically, after obtaining the plurality of data blocks, the execution subject may calculate the second parity code corresponding to each data block according to the cyclic redundancy check algorithm again.
After the execution main body obtains the second check code corresponding to each data block, the second check code corresponding to each data block can be compared with the first check code carried by the execution main body, if the second check code and the first check code are the same, the audio data is correctly transmitted, and the plurality of data blocks can be arranged and combined according to a preset sequence to restore the target data.
In the embodiment, the second check code calculated again according to the cyclic redundancy check algorithm is compared with the first check code carried by the audio data, so that whether the transmitted audio data is wrong or not can be determined, if the second check code is the same as the first check code, the audio data is correctly transmitted, and the target data is restored by arranging and combining the plurality of data blocks, so that the method has the effects of less limitation of equipment, difficulty in environmental influence, larger transmission bandwidth and broadcasting.
