A data transmission device of an existing communication system is generally a transmitter, and a main task of the transmitter (a transmitter circuit) is to modulate a high-frequency carrier wave with a useful low-frequency signal, so as to convert the high-frequency carrier wave into an electromagnetic wave which has a certain bandwidth at a certain center frequency and is suitable for being transmitted through an antenna. The transmitter general workflow can be summarized as: generating a bit stream corresponding to data to be sent by software; in a baseband part, a bit stream is subjected to modulation and other operations to generate a digital signal and is stored; when the data needs to be sent, the stored data is read, and an analog signal is generated and sent out after digital-to-analog conversion and radio frequency processing. When a general transmitter transmits some signals, the following problems exist: when sending a long pulse signal, the long pulse signal has a transmission time as long as a second, and if such a long signal is generated by software, is stored in a baseband memory after being modulated by a baseband, and is sent out by hardware, then very large memory resources are consumed, for example, if the sampling rate is 240Msps, the signal bit width is 32bit, and the storage space required for a signal with a transmission time of 12 seconds is 240 × 32 × 12 ^ 10^6 ^ 92.16Gbit, which is difficult for a transmitter to accept, if all the long pulse signals are sent out while being generated by hardware, the design difficulty of the transmitter is greatly increased, and the cost of the transmitter is also increased. Moreover, when some identical repeated signals are transmitted, the situation that the identical digital signals are stored in multiple copies occurs in the baseband, and the memory resources of the baseband are wasted. In order to solve the above problem, an embodiment of the present application provides a data transmission method.

Referring to fig. 1, fig. 1 is a schematic flow chart of a data transmission method according to a first embodiment of the present application. In this embodiment, a main body of the data transmission method is a device having a data transmission function, for example, a transmitter. The data transmission method as shown in fig. 1 may include:

s101: acquiring a first reading period parameter; the first reading period parameters include a sleep duration and a first reading data length of a non-sleep period corresponding to each first reading period, and the first reading period includes a sleep period and a non-sleep period.

In this embodiment, the device may include a buffer area and a storage area, where the data to be sent may be stored in the buffer area, and the buffer area reads the data to be sent from the storage area. When the device detects a data transmission instruction, data is read from the buffer area. In this embodiment, when reading data from the buffer area, the reading cycle is divided into a sleep period and a non-sleep period to meet the requirements 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 read signal may be generated by a first read parameter and a first preset counting rule, and the first read parameter may include a sleep duration and a first read data length in each first read cycle, and the number of the first read cycles. The device may further obtain relevant parameters of the first read queue, for example, the first read cycle parameters may further include the number N _ sequence _ rep of the first read queue sequence, the number N _ frame (N) _ rep of different first read cycles included in the first read queue, and the like, in addition to the sleep time and the first read data length in each first read cycle frame, and the number of first read cycles. The parameters can be preset and stored in the first parameter storage area. The queue parameter control unit in the device may generate a first read signal to read the first data from the storage area according to the first read parameter and a first preset count rule.

All parameters required to be obtained in this embodiment are described below by taking fig. 2 as an example. Defining all data to be transmitted as a data queue, called sequence, configuring the repeated transmission times (N _ sequence _ rep) of the data queue sequence, wherein the data queue sequence is composed of a plurality of first reading period frames, the number (N _ frame) of the first reading period 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 indicates that the number of first read cycles of frame (1) is 2, and 3_ frame (2) _ rep indicates that the number of first read cycles of frame (2) is 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 of each first read cycle frame and the first read data length pulse _ len of the non-sleep period pulse can be individually configured. The pulse _ len represents the length of data required to be sent in the non-sleep period pulse part of the current first read cycle frame, and specific data in the pulse can be preset and stored in the non-buffer area. As shown in fig. 2, N _ sequence _ rep is configured to be 2, which means that the entire data queue is repeatedly transmitted 2 times; n _ Frames are configured as 3, meaning that sequence contains 3 frames, frame1, frame2, and frame 3; n _ frame (1) _ rep, N _ frame (2) _ rep, and N _ frame (3) _ rep are software configured such that N _ frame (1) _ rep is 2, N _ frame (2) _ rep is 1, and N _ frame (3) _ rep is 1, indicating 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 duration 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. And only in the non-sleep period, reading corresponding data from the buffer area. In the dormancy period, the reading of the data is stopped, and in the duration of the dormancy period, the filled data does not need to be generated, the storage resource does not need to be occupied, 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. Therefore, data corresponding to multiple groups of first reading periods can be 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 duration.

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, and the filled data does not need to be generated in the dormant period, and the storage resource does not need to be occupied.

In order to accurately read 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 data to be read in the sleep period of the first reading period, starting a first counter, and entering the non-sleep period of the first reading period after the first counter finishes timing; and the timing duration of the first counter is the dormancy duration. For example, the first counter is set to be 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 to wait for the next counting.

S103: and reading first data corresponding to the first reading period from the data to be read according to the first reading data length in the non-sleep period of the first reading period, and entering the sleep period of the next first reading period.

The device reads first data corresponding to a first reading period from the data to be read according to the first reading data length in a non-sleep period of the first reading period, and enters a sleep 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 also be read in a counter manner. And when the non-sleep period is entered, starting a second counter, wherein the second counter starts to work, and the counting range of the second counter is the first reading data length. For example, the second counter is set to be a pulse1 counter, the first read data length is pulse _ len (1), a read data signal is generated in the non-sleep period of the first read cycle, 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 counting is waited, the read data signal is turned off, and then the next first read cycle is started.

And reading the data with the first read data length from a first preset starting position of the buffer area in the non-sleep period of the first read period to obtain first data corresponding to the first read period. The cache area stores data to be read in different ways, and the first preset starting position is 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, and the buffer area includes all the data to be sent. In each non-sleep period, the device acquires the storage position of the data corresponding to the first reading period in the cache region, and reads the first data according to the storage position. In another embodiment, the buffer area stores only data corresponding to the first read data length of the non-sleep period from the first preset starting position each time, and deletes old data and stores new data from the first preset starting position each time data corresponding to the first read data length of the new non-sleep period is detected. The device starts reading from the first preset starting position each time the device reads data from the buffer area. For example, when the first data is read, the first data may be read by using a counter, the second counter starts to operate, when the count value of the second counter reaches pulse _ len (1), the pulse repetition number counter increments by 1, but does not reach a set value of 2, the second counter returns to 1 to count again, and the count range is still 1 to pulse _ len (1); in the above example, the second counter returns to 1 to count each time, where 1 is the first preset starting position, and when reading each time, the first data is read from the same first preset starting position, so that an excessive storage space is not required, and resources are further saved.

Since the read parameter and the parameter of the buffer area are preset, when the device finishes reading the first data corresponding to one first read cycle from the buffer area, the buffer area updates the data corresponding to the first read data length of the non-sleep period of the next first read cycle. This requires the storage area to store new data to the first predetermined starting position of the buffer area. In this embodiment, a buffer area is set, and a storage area is set, where initial data of data to be transmitted is stored.

Further, before S101, S105 to S106 may be further included, as shown in fig. 3, S105 to S106 are specifically as follows:

s105: acquiring a second reading period parameter; the second read cycle parameters include a second read data length for each second read cycle.

And the device acquires a second reading period parameter, wherein the second reading period parameter comprises the length of second reading data in each second reading period, reads the data to be read from the storage area according to the second reading period parameter, and stores the data to be read into the cache area. The second read parameters may include a second read data length and the number of second read cycles in each second read cycle. The device may further acquire relevant parameters of the second read queue, for example, the second read cycle parameter may further include, in addition to the length of the second read data in each second read cycle frame and the number of second read cycles, the number N _ sequence _ rep of second read queues, the number N _ frame (N) _ rep of different second read cycles included in the second read queues, and so on. The parameters can be preset and stored in the second parameter storage area.

S106: and reading the data to be read from the storage area according to the second reading period parameter, and storing the data to be read to the cache area.

Specifically, the apparatus reads the second data from the storage area by generating the second read signal, and stores the second data into the buffer area. The second read signal may be generated by the second read parameter and a second preset counting rule, and the memory control unit in the device may generate the second read signal according to the second read parameter and the second preset counting rule to read the second data from the storage area.

Further, S106 may include S1061 to S1062, as shown in fig. 4, S1061 to S1062 are specifically as follows:

s1061: and reading the data to be read with the length of the second read data from a second preset initial position of the storage area to obtain second data.

And the device reads the data to be sent with the second read data length from the second preset initial position of the storage area to obtain second data. It can be understood that, before the device reads data from the buffer area and transmits the data, the data is read from the memory area and stored in the buffer area according to the configuration of the second reading parameter, and waits to be read. And after the data in the cache region is read out, so that the number of the data in the cache region is reduced, the cache region requests new data from the storage region, and the new data is still read out according to the configuration of the second reading parameter and is stored in the cache region. It is understood that the buffer is data regardless of whether data is sent or not. That is, the second data is read from the storage area and stored in the buffer area as configured by the second read parameter.

S1062: and starting to store the second data from the first preset starting position of the cache region.

The device starts to store the second data from a first preset starting position of the buffer area. For example, the first preset starting position is address 1, and the device starts to store the second data from address 1, overwriting the old second data stored before.

When the number of the data in the buffer area is less than the threshold, in order to avoid the buffer area being read empty when the data is transmitted, before the data is read from the buffer area and transmitted, the second data is already read from the memory area and stored in the buffer area according to the configuration of the second reading parameter, and the second data is waited to be read. After the second data in the cache area is read out, and the number of the data in the cache area is reduced and is smaller than the threshold value, the cache area requests the new second data from the storage area, and the new second data is still read out and stored in the cache area according to the configuration of the second reading parameters.

Further, before S1061, 10611 to 10612 may be further included, as shown in fig. 5, 10611 to 10612 are specifically as follows:

10611: and acquiring the data to be transmitted and acquiring an initial position of a second preset initial position.

The device obtains data to be sent and obtains the initial position of the second starting position. For example, address 1 in the storage area may be the initial position of the second start position.

10612: and storing the data to be transmitted from the initial position of the second preset initial position of the storage area.

And the equipment starts to store the data to be sent from the initial position of the second initial position of the storage area and stores the data to be sent to the corresponding address of the storage area.

On the basis of S105 to S106, S107 to S109 may be further included after S101, and as shown in fig. 6, S107 to S109 are specifically as follows:

s107: acquiring a cumulative number of repetitions before a non-sleep period of the first read cycle.

The device obtains the accumulated number of repetitions before the non-sleep period of the first read cycle. In this embodiment, the accumulated number of repetitions is for the first read cycle, and 1 is added to the accumulated number of repetitions each time the first read cycle completes reading. Each first read period 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 indicates that the number of first read cycles of frame (1) is 2, and 3_ frame (2) _ rep indicates that the number of first read cycles of frame (2) is 3.

S108: and if the accumulated repetition times is smaller than the repetition time threshold, reading the second data in the cache region to obtain first data, and adding 1 to the accumulated repetition times.

After the device reads the first data from the buffer area each time, whether the accumulated repetition number is less than the repetition number threshold value or not is judged. And if the accumulated repetition number is smaller than the repetition number threshold, indicating that the first data still needs to be continuously read from the buffer area again at present, reading the first data from the buffer area, and adding 1 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 each time, the size of the accumulated repetition number and the size of the repetition number threshold are judged. If the accumulated repetition number is equal to the repetition number threshold, it indicates that another first reading period needs to be started currently. The device resets the accumulated number of repetitions to an initial value, recalculates the number of repetitions for a new first read cycle, and waits for the next first read cycle.

S104: and converting the first data into an analog signal, and transmitting the analog signal.

The first data read by the equipment are digital signals, and the equipment sends the analog signals after converting the digital signals into the analog signals.

After the device obtains the data to be sent, the device stores all the data to be sent in the storage region, and the memory control unit in the device may generate a second read signal according to a second read cycle parameter of the second parameter storage region and a second preset count rule, so as to read the second data from the storage region and store the second data in the cache region. When the data sending instruction is detected, the queue parameter control unit in the device may generate a first read signal according to the first read cycle parameter and a first preset counting rule, and read the first data from the buffer area.

When the device reads the second data from the storage area, a counter mode may be adopted, a data waveform of the second read cycle parameter is as shown in fig. 7, in this embodiment, a counter is set for each parameter, pulse _ len (1) means that the length of the second read data in the second read cycle is pulse _ len (1), the number of second read queues is N _ sequence _ rep is 2, the number of second read cycles with length of pulse _ len (1) is N _ pulse (1) _ rep is 2, and the number of second read cycles with length of pulse _ len (2) is N _ pulse (2) _ rep is 1. When the count value of the read address counter reaches pulse _ len (1), that is, data of the length of pulse _ len (1) has been read in the second read cycle, it needs to be determined whether the number of pulse repetitions reaches the number of the second read cycle:

adding 1 to a pulse repetition number counter, but not reaching the number 2 of the second reading period;

b. the read address counter returns to address 1 to count again, and the counting range is still 1-pulse _ len (1);

thereafter, the read address counter continues to operate until the read address counter reaches pulse _ len (1) for the 2 nd time:

adding 1 to a pulse repetition number counter, and changing the counting range of the pulse repetition number counter into 1-N _ pulse (2) _ rep when the set value is 2;

b. the counting range of the reading address counter is changed into pulse _ len (1) + 1-pulse _ len (2);

and c, adding 1 to the pulse number counter.

Thereafter, the read address counter continues to operate, and when the read address counter reaches the pulse _ len (2):

adding 1 to the count value of a pulse repetition number counter, and changing the counting range of the pulse repetition number counter into 1-N _ pulse (1) _ rep when the count value reaches a set value of 1;

b. the counting range of the reading address counter is changed by 1 to pulse _ len (1);

adding 1 to a pulse number counter, and reaching a set value of 2;

the sequence repetition counter is incremented by 1, and since the set value of 2 is not reached, the data is repeatedly read once thereafter.

Similar subsequent processes are not repeated, and the device stores the read second data in the cache area.

The first read cycle parameters may include a sleep duration and a first read data length in each first read cycle, and the number of first read cycles. The parameters related to the first read queue may be further included, for example, as shown in fig. 8, fig. 8 is a data waveform diagram of the parameters of the first read cycle. The first read cycle parameters may include the number of first read queue sequences N _ sequence _ rep, the number of different first read cycles included in the first read queue N _ frame (N) _ rep, and so on, in addition to the sleep duration and the first read data length in each first read cycle frame, and the number of first read cycles. When the device detects a data transmission instruction, first data is read from the buffer area. In this embodiment, the parameters are set to be the number of the first read queues N _ sequence _ rep is 2, the number of the first read cycles frame (2) is N _ frame (2) _ rep is 1, the number of the first read cycles frame (1) is N _ frame (1) _ rep is 2, and N _ frame is 2, when the device reads the first data from the buffer area, a counter mode may be adopted, in this process, one counter is set for each parameter, and when starting, the sleep period timer delay counter starts to operate, and when the count value of the delay counter reaches delay _ len (1):

resetting the count value of the delay counter and waiting for counting next time;

b. and generating a read data signal;

the pulse counter starts to operate, counting in the range 1 to pulse _ len (1).

When the count value of the pulse counter reaches pulse _ len (1):

resetting a pulse counter and waiting for counting next time;

b. turning off the read data signal;

and c, adding 1 to a frame repetition counter.

Since the number of frame repetitions does not reach the set value of 2, frame1 is sent repeatedly 1 time thereafter, and the process is not repeated. When the number of frame repetition reaches the set value 2, it is considered that the frame1 is sent completely, and the following operations are completed:

resetting a frame repetition number counter;

adding 1 to the frame number counter, but not reaching a set value of 2;

c. the frame2 transmission is started, in which case, the counting range of the delay counter is changed from 1 to delay _ len (1) to 1 to delay _ len (2), the counting range of the pulse counter is changed from 1 to pulse _ len (1) to 1 to pulse _ len (2), and the counting range of the frame repetition counter is changed from 1 to N _ frame (1) _ rep to 1 to N _ frame (2) _ rep.

The process of transmitting frame2 is similar to frame1 and will not be described in detail. When the frame2 is sent out, the controller completes the following operations:

adding 1 to the frame number counter, and reaching a set value of 2, and resetting the frame number counter and the frame repetition frequency counter;

adding 1 to the count value of the sequence repetition number counter;

however, the count value of the sequence counter does not reach the set value 2, so the sequence is repeatedly sent for 1 time, the sending process is similar to that of the 1 st time, and the description is omitted.

In addition, the first reading period parameter and the second reading period parameter in this embodiment may be configured according to different sending modes, that is, the data sending method of the present application may support multiple sending modes.

In the embodiment of the application, a first reading period parameter corresponding to data to be sent is obtained; stopping reading 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 duration; reading first data corresponding to the first reading period from the data to be read according to the first reading data length in a non-sleep period of the first reading period, and entering a sleep period of the next first reading period; and converting the first data into an analog signal, and transmitting the analog signal. According to the method, during the period of the sleep period, the filled data does not need to be generated, the storage resources do not need to be occupied, when the data volume is large, the data sending mode can save a lot of storage resources, the hardware implementation of the transmitter is easy, and the cost of the transmitter is reduced.
