The data transmission device of the existing communication system is generally a transmitter, and the main task of the transmitter (A TRANSMITTER circuit) is to perform modulation of a useful low-frequency signal to a high-frequency carrier wave, and to change the modulation into an electromagnetic wave with a certain bandwidth at a certain center frequency and suitable for being transmitted through an antenna. The transmitter general workflow can be summarized as: generating a bit stream corresponding to data to be transmitted by software; in the baseband part, the bit stream generates a digital signal through operations such as modulation and the like and stores the digital signal; when the data is required to be transmitted, the stored data is read, subjected to digital-to-analog conversion and radio frequency processing, and then an analog signal is generated and transmitted. A general transmitter has the following problems when transmitting some signals: when a long pulse signal is transmitted, the long pulse signal is up to the second level due to the long transmission time, if the long pulse signal is generated by software, is stored in a baseband memory after being modulated by a baseband and is transmitted by hardware, very large memory resources are required to be consumed, for example, if the sampling rate is 240Msps, the signal bit width is 32 bits, the storage space required for transmitting a signal with the time length of 12 seconds is 240 x 32 x 12 x10 x 35 gbit= 92.16Gbit, which is unacceptable for a transmitter, and if all the long pulse signal is generated by the hardware and is transmitted, the design difficulty of the transmitter is greatly increased, and the cost of the transmitter is also increased. And, when transmitting some identical repeated signals, the situation that the same digital signal is stored in multiple parts occurs in the baseband, which wastes the memory resources of the baseband. In view of the above problems, the embodiment of the application provides a data transmission method.
Referring to fig. 1, fig. 1 is a schematic flowchart of a data transmission method according to a first embodiment of the present application. The execution body of a data transmission method in this embodiment is a device having a data transmission function, for example, a transmitter or the like. The data transmission method as shown in fig. 1 may include:
S101: acquiring a first reading period parameter; the first reading period parameters comprise a sleep period and a non-sleep period corresponding to each first reading period, and the first reading period comprises a sleep period and a non-sleep period.
In this embodiment, the device may include a buffer area and a storage area, where data to be sent may be stored, and the buffer area reads the data to be sent from the storage area. When the device detects a data transmission instruction, the data is read from the cache area. In this embodiment, when data is read from the buffer area, the reading period is divided into a sleep period and a non-sleep period to adapt to the needs of various data waveforms.
The device obtains a first read cycle parameter. The first reading period parameter may be preset, and the first reading period parameter is determined according to the first reading signal. The first reading signal may be generated by a first reading parameter and a first preset counting rule, and the first reading parameter may include a sleep time length and a first reading data length in each first reading period, and the number of first reading periods. The device may further obtain parameters related to the first read queue, for example, the first read cycle parameters may include, in addition to the sleep duration and the first read data length in each first read cycle frame, the number of first read cycles, the number of first read queue sequences n_sequence_rep, the number of different first read cycles n_frames (N) _rep included in the first read queue, and so on. The parameters may be preset and stored in the first parameter storage area. The queue parameter control unit in the device may generate a first read signal according to the first read parameter and a first preset count rule, and read the first data from the storage area.
In the following, taking fig. 2 as an example, all parameters to be acquired in the present embodiment will be described. Defining all data to be transmitted as a data queue, called sequence, the repeated transmission times (n_sequence_rep) of the data queue sequence can be configured, the data queue sequence is composed of a plurality of first reading periods frames, the number (n_frames) of the first reading periods frames can be configured in advance, and each first reading period frame can be configured with different repeated transmission times: n_frame (1) _rep, N_frame (2) _rep, N_frame (N) _rep. For example, 2_frame (1) _rep represents frame (1) as a number of first read cycles of 2, and 3_frame (2) _rep represents frame (2) as a number of first read cycles of 3. Each first read cycle frame is composed of 1 sleep period delay and 1 non-sleep period pulse, and the duration delay_len of the sleep period delay and the first read data length pulse_len of the non-sleep period pulse of each first read cycle frame can be independently configured. pulse_len represents the data length that needs to be transmitted for the non-sleep period pulse portion of the current first read cycle frame, and specific data in pulse may be preset and stored in the non-cache area. As shown in fig. 2, n_sequence_rep is configured to be 2, indicating that the entire data queue will be repeatedly transmitted 2 times; n_frame is configured to be 3, meaning that 3 frames are included in the sequence, frame1, frame2, and frame3, respectively; n_frame (1) _rep, n_frame (2) _rep, and n_frame (3) _rep are software configured to n_frame (1) _rep=2, n_frame (2) _rep=1, n_frame (3) _rep=1, meaning that frame1 needs to be repeatedly transmitted 2 times, frame2 needs to be repeatedly transmitted 1 time, and frame3 needs to be repeatedly transmitted 1 time.
The first reading period parameters comprise a sleep period and a first reading data length corresponding to each first reading period, the first reading period comprises a sleep period and a non-sleep period, and each reading period comprises a sleep period and a non-sleep period. Only during the non-sleep period, the corresponding data is read from the cache region. And in the dormant period, reading of the data is stopped, and the filled data does not need to be generated in the dormant period, so that the occupied storage resource is not needed, and the cost is reduced.
The first read cycle parameter may include a sleep duration and a first read data length corresponding to a plurality of different first read cycles. Thus, the data corresponding to the plurality of groups of first reading periods are read according to the parameters of each first reading period.
S102: and stopping reading the data to be read in the dormant period of the first reading period, and entering the non-dormant period of the first reading period after waiting for the dormant period.
The device stops reading the data to be read in the dormant period of the first reading period, and enters the non-dormant period of the first reading period after waiting for the dormant period, so that the filled data does not need to be generated in the dormant period, and storage resources do not need to be occupied.
In order to accurately read the data to be read after the sleep period has elapsed, a counter may be set for the sleep period, and S102 may include: stopping reading the data to be read in the dormant period of the first reading period, starting a first counter, and entering the non-dormant period of the first reading period after the first counter is timed out; and the timing duration of the first counter is the sleep duration. For example, the first counter is set as a delay1 counter, the duration of the sleep period is delay_len (1), reading of data to be read is stopped in the sleep period of the first reading period, the delay1 counter is started, and when the count value of the delay1 counter reaches delay_len (1), the count value of the delay1 counter is reset and the next counting is waited.
S103: and in the non-dormant period of the first reading period, reading the first data corresponding to the first reading period from the data to be read according to the first reading data length, and entering the dormant period of the next first reading period.
The device reads the first data corresponding to the first reading period from the data to be read according to the first reading data length in the non-dormant period of the first reading period, and enters the dormant period of the next first reading period.
In this embodiment, when the first data is read in the non-sleep period, the first data may be read by using a counter. When the non-sleep period is entered, a second counter is started, the second counter starts to work, and the counting range of the second counter is the length of the first read data. For example, the second counter is set as a pulse1 counter, the first read data length is pulse_len (1), during the non-sleep period of the first read cycle, a read data signal is generated, the first data corresponding to the first read cycle is read from the data to be read according to the first read data length, the pulse1 counter is started, when the count value of the pulse1 counter reaches the pulse_len (1), the count value of the pulse1 counter is reset, the next count is waited, the read data signal is closed, and then the next first read cycle is entered.
And in the non-dormant period of the first reading period, reading the data with the first reading data length from a first preset starting position of the cache area to obtain first data corresponding to the first reading period. The mode of storing the data to be read in the buffer area is different, and the first preset starting position is also different. In one embodiment, the data to be read may be stored according to the duration of the sleep period and the first read data length of the non-sleep period in the first read cycle parameter, where the buffer area includes all the data to be sent. And in each non-dormancy period, the device acquires the storage position of the data corresponding to the first reading period in the cache area, and reads the first data according to the storage position. In another embodiment, the buffer area stores only the data corresponding to the first read data length of the non-sleep period from the first preset starting position at a time, deletes the old data whenever the data corresponding to the first read data length of the new non-sleep period is detected, and stores the new data from the first preset starting position. The device starts reading from a first preset starting position every time it reads data from the cache area. For example, when the first data is read, the first data may be read by adopting a counter mode, the second counter starts to work, when the count value of the second counter reaches pulse_len (1), the pulse repetition count is increased by 1, but the set value of 2 is not reached, the second counter returns to 1 to count again, and the count range is still 1-pulse_len (1); in the above example, the second counter returns to 1 again for counting every time, 1 is the first preset starting position, and the first data is read from the same first preset starting position every time when the first data is read, so that an excessive storage space is not needed, and resources are further saved.
Because the reading parameters and the parameters of the buffer area are all preset, when the device reads the first data corresponding to one first reading period from the buffer area, the data corresponding to the first reading data length of the non-sleep period of the next first reading period is updated in the buffer area. This requires the storage area to constantly store new data to the first preset starting position of the cache area. In this embodiment, a buffer area is set, and a storage area is set at the same time, in which initial data of data to be transmitted is stored.
Further, before S101, S105 to S106 may be further included, and as shown in fig. 3, S105 to S106 are specifically as follows:
S105: acquiring a second reading period parameter; the second read cycle parameter includes a second read data length of each second read cycle.

The second reading parameter may include a second reading data length and the number of second reading cycles in each second reading cycle. The device may further obtain relevant parameters of the second read queue, for example, the second read cycle parameter may include, in addition to the second read data length in each second read cycle frame, the number of second read cycles, the number n_sequence_rep of the second read queue sequences, the number n_frame (N) _rep of different second read cycles included in the second read queue, and so on.

And the equipment starts from a second preset starting position of the storage area, reads the data to be sent of a second read data length, and obtains second data. It will be appreciated that the device has data read from the storage area and stored in the buffer area in accordance with the configuration of the second read parameter, awaiting reading, before reading the data from the buffer area and transmitting. After waiting for the data in the buffer area to be read out, the buffer area requests new data from the storage area after the number of the data in the buffer area is reduced, and the new data is still read out and stored in the buffer area according to the configuration of the second reading parameter. It is understood that the buffer is data whether or not data is transmitted. That is, the second data is read out from the storage area as configured according to the second read parameter and stored in the buffer area.
S1062: and storing the second data from the first preset starting position of the cache area.
The device stores the second data from a first preset starting position of the cache area. For example, the first preset starting position is address 1, and the device stores the second data from address 1, and overwrites the old second data stored previously.
When the number of data in the buffer area is smaller than the threshold value, the buffer area is read out to avoid the condition that the buffer area is empty when the data is transmitted, and before the data is read from the buffer area and transmitted, the second data is read out from the storage area and stored in the buffer area to wait for being read according to the configuration of the second reading parameter. After the second data in the buffer area is read out, the buffer area requests new second data from the storage area after the number of the data in the buffer area is reduced and is smaller than the threshold value, and the new second data is still read out and stored in the buffer area according to the configuration of the second reading parameter.

S107: the accumulated number of repetitions is acquired before a non-sleep period of the first read cycle.
The device obtains a cumulative number of repetitions prior to a non-sleep period of the first read cycle. In this embodiment, the cumulative repeat count is increased by 1 for the first reading period after the first reading period finishes reading. Each first read cycle frame may be configured with a different number of repeated transmissions: n_frame (1) _rep, N_frame (2) _rep, N_frame (N) _rep. For example, 2_frame (1) _rep represents frame (1) as a number of first read cycles of 2, and 3_frame (2) _rep represents frame (2) as a number of first read cycles of 3.
S108: and if the accumulated repetition number is smaller than the repetition number threshold, reading the second data in the buffer area to obtain the first data, and adding 1 to the accumulated repetition number.
After the device reads the first data from the buffer area, it is determined whether the accumulated repetition number is smaller than a repetition number threshold. If the accumulated repetition number is smaller than the repetition number threshold, the first data is read from the cache area if the accumulated repetition number is still needed to be read again, and 1 is added to the accumulated repetition number.
S109: and if the accumulated repetition number is equal to the repetition number threshold, resetting the accumulated repetition number to the initial value and waiting for the next first reading period.
After the device reads the first data from the buffer area, the device determines the accumulated repetition number and the threshold value of the repetition number. If the accumulated number of repetitions is equal to the repetition threshold, it is indicated that another first read cycle is currently required to begin. The device resets the accumulated repetition number to an initial value, recalculates the repetition number of the new first reading period, and waits for the next first reading period.
S104: and converting the first data into an analog signal and transmitting the analog signal.
The first data read by the device are digital signals, and the device converts the digital signals into analog signals and then sends the analog signals.
The data transmission method provided in this embodiment is described below with reference to a specific application:
The transmitting device comprises a queue parameter control unit, a memory control unit and a storage area, wherein the queue parameter control unit comprises a first parameter storage area and a data transmission control logic unit, and the memory control unit comprises a second parameter storage area, a cache area and a memory read address control logic unit.
After the data to be sent is obtained from the device, the data to be sent is stored in the storage area, and the memory control unit in the device can generate a second reading signal according to the second reading period parameter of the second parameter storage area and a second preset counting rule so as to read the second data from the storage area and store the second data in the cache area. When a data transmission instruction is detected, a queue parameter control unit in the device can generate a first reading signal according to a first reading period parameter and a first preset counting rule, and read first data from a cache area. The device converts the first data into an analog signal and transmits the analog signal.
The second read cycle parameter may include a second read data length pulse_len (N) in the second read cycle, a number n_pulse (N) _rep of the second read cycle, a number n_sequence_rep of the second read queue sequence in addition to the second read data length in each second read cycle frame, the number of second read cycles, a number n_frame (N) _rep of different second read cycles included in the second read queue, and the like. When the apparatus reads the second data from the storage area, a counter manner may be adopted, and the data waveform of the second read cycle parameter is shown in fig. 7, in this embodiment, one counter is set for each parameter, and in this process, pulse_len (1) means that the second read data length is pulse_len (1) in the second read cycle, the number n_sequence_rep=2 of the second read queues, the number n_pulse (1) _rep=2 of the second read cycle with the length of pulse_len (1), and the number n_pulse (2) _rep=1 of the second read cycle with the length of pulse_len (2). When the count value of the read address counter reaches pulse_len (1), that is, the data with the length of pulse_len (1) has been read in the second reading period, it is necessary to determine whether the number of pulse repetition times reaches the number of second reading periods:
a, adding 1 to the pulse repetition counter, but not reaching the number 2 of the second reading period;
b. the read address counter returns to address 1 to recount, and the counting range is still 1-pulse_len (1);
The read address counter then continues to operate until the count value of the read address counter reaches pulse_len (1) 2 nd time:
adding 1 to the pulse repetition counter and reaching a set value of 2, and changing the counting range of the pulse repetition counter to 1-N_pulse (2) _rep;
b. The count range of the read address counter is changed to pulse_len (1) +1 to pulse_len (2);
and c, adding 1 to the pulse number counter.
The read address counter then continues to operate until the read address counter count reaches pulse_len (2):
a, adding 1 to the count value of the pulse repetition counter, and reaching a set value of 1, wherein the count range of the pulse repetition counter is changed to 1-N_pulse (1) _rep;
b. the count range of the read address counter is changed by 1 to pulselen (1);
adding 1 to the pulse number counter and reaching a set value of 2;
The sequence repetition counter is incremented by 1, and since the set value 2 is not reached, the data is read again thereafter.
The subsequent process is similar and will not be repeated, and the device stores the read second data in the cache area.
The first read cycle parameters may include a sleep time length and a first read data length in each first read cycle, and the number of first read cycles. The method may further include the related parameters of the first read queue, for example, as shown in fig. 8, and fig. 8 is a data waveform diagram of the parameters of the first read cycle. The first read cycle parameter may include, in addition to the sleep duration and the first read data length in each first read cycle frame, the number of first read cycles, the number of first read queue sequences n_sequence_rep, the number of different first read cycles n_frames (N) _rep included in the first read queue, and so on. When the device detects a data transmission instruction, the first data is read from the cache area. In this embodiment, the parameter is set to n_sequence_rep=2, the number of first read cycles frame (2) is n_frame (2) _rep=1, the number of first read cycles frame (1) is n_frame (1) _rep=2, and n_frame=2, when the device reads the first data from the buffer area, a counter may be set for each parameter, and in this process, a timer is set, and at the beginning, the sleep timer delay counter starts to work, and when the count value of the delay counter reaches delay_len (1):
Resetting the count value of the delay counter, and waiting for the next counting;
b. and generating a read data signal;
the pulse counter starts to work, and the counting range is 1 to pulse_len (1).
When the count value of the pulse counter reaches pulse_len (1):
resetting a pulse counter, and waiting for the next counting;
b. Closing the read data signal;
frame repetition counter is incremented by 1.
Since the repetition number of frames does not reach the set value of 2, frame1 is repeatedly transmitted 1 time thereafter, and the procedure is similar and will not be repeated. When the repetition number of the frame reaches the set value of 2, the frame1 is considered to be sent completely, and the following operations are completed simultaneously:
Resetting a frame repetition counter;
the frame number counter is incremented by 1, but does not reach the set point 2;
c. At this time, the count range of the delay counter is changed from 1 to delay_len (1) to 1 to delay_len (2), the count range of the pulse counter is changed from 1 to pulse_len (1) to 1 to pulse_len (2), and the count range of the frame repetition counter is changed from 1 to N_frame (1) _rep to 1 to N_frame (2) _rep.
The transmission process of frame2 is similar to that of frame1 and will not be described again. When frame2 is sent, the controller simultaneously completes the following operations:
adding 1 to the frame number counter, and reaching a set value of 2, wherein the frame number counter and the frame repetition number counter are reset;
The count value of the sequence repetition number counter is increased by 1;
however, the count value of the sequence counter does not reach the set value 2, so the sequence is repeatedly sent for 1 time, and the sending process is similar to the 1 st time and is not repeated.
In addition, the first reading period parameter and the second reading period parameter in the present embodiment may be configured according to different transmission modes, that is, the data transmission method of the present application may support multiple transmission modes.
