Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, in particular to a data transmission method and device. BACKGROUND

[0002] With the development of science and technology, the wireless transmission technology of electronic devices also progresses. In the process of transmitting data using wireless transmission technology, the specific sending and receiving are generally performed by the wireless transmission module built-in in the electronic device, that is, the wireless transmission end. That is to say, when the main chip end processes the data and obtains the data to be transmitted, the data to be transmitted is first sent to the wireless transmission end, and then the wireless transmission end transmits the data to be transmitted to other electronic devices by using the wireless transmission mode. Conversely, when the electronic device receives data based on the wireless transmission technology, the wireless transmission end first receives the data, and then transmits the data to the main chip end for processing.

[0003] At present, in the process of transmitting data by using the wireless transmission technology, multiple different data need to be divided into different data packets and transmitted between the main chip end and the wireless transmission end in turn. When the data amount of each data packet is small, for example, the data amount of each data packet is 1 kb or 2 kb, the transmission between the electronic devices is performed at the speed of kilobyte level, so that the data transmission efficiency between the electronic devices is low.

[0065] Exemplary embodiments of the present application will be described in detail with reference to the drawings. Although exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this application will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.

[0066] It should be noted that, unless otherwise specified, technical terms or scientific terms used in the present application should be understood as their common meanings to those skilled in the art to which the present application pertains.

[0067] An embodiment of the present application provides a flowchart of a data transmission method, which is applied to a slave device, such as a wireless transmission end in an electronic device. Figure 1 As shown in the figure, the method comprises the following steps.

[0068] 101. Obtain a plurality of target data to be transmitted.

[0069] In the present embodiment, the method is applied to a data transmission process between a master chip end and a wireless transmission end in an electronic device, which includes a process of transmitting data from the internal master chip end to the wireless transmission end when the electronic device sends data to the outside world, and a process of transmitting data from the internal wireless transmission end to the master chip end when the electronic device receives data sent by the outside world. Therefore, based on different processes, the execution subject of the present embodiment is also different.

[0070] Here, in order to facilitate description, the method of the present embodiment is applied to the process of sending data to the outside world by the electronic device, so that the execution subject of the present embodiment is the master chip end. Based on this, in the present step, when the master chip end obtains data that needs to be transmitted to the outside world after processing, it needs to determine which data is the target data that needs to be sent to the wireless transmission end, and obtain the target data.

[0071] 102. Combine the plurality of target data according to a preset rule to obtain a data block.

[0072] Among them, the data block contains two or more target data; the preset rule is used to limit the number of target data when combining the data block.

[0073] After the above steps obtain multiple target data, the multiple target data blocks need to be combined. The combination process selects a certain number of target data according to a preset rule. The method described in the embodiment is mainly to improve the efficiency of data transmission, so the number of selected target data is greater than or equal to two or more, that is, when there are multiple target data, at least two target data are selected to form a data block. In addition, it should be noted that the number of target data defined by the preset rule in the embodiment can be selected based on the needs of the user, and of course, the transmission bandwidth of the transmission channel between the main chip end and the wireless transmission end should also be considered to avoid the problem that the overall data amount of the data block composed of too much target data is too large to be sent at a time.

[0074] 103. Transmitting the data block to the target end for processing by the target end.

[0075] The target end includes a main chip end and a wireless transmission end.

[0076] After the multiple target data are combined into a data block, the data block can be directly transmitted to the target end, that is, the wireless transmission end. The specific transmission method can be selected according to the transmission channel between the main chip end and the wireless transmission end, which includes but is not limited to a USB channel (Universal Serial Bus, USB for short), a PCIE channel (peripheral component interconnect express, PCIE for short), and an SDIO channel (Secure Digital Input and Output, SDIO for short). In this way, it is ensured that multiple target data can be transmitted in the form of a data block during data transmission, avoiding the waste of transmission channel bandwidth caused by transmitting one target data at a time, and improving the data transmission efficiency. Moreover, after the target end receives the data block, it is parsed, which is equivalent to receiving multiple target data at the same time, avoiding the process of triggering a receiving event and processing each time when the target end receives target data in a conventional manner, thereby avoiding the problem of resource occupation and consumption of the target end caused by processing these events.

[0077] In an optional implementation, the method described in the embodiment can be applied to a system as shown in FIG. 1. Figure 2The system architecture shown. Among them, when the embodiment of the method is applied to the scene of the smart TV interacting with the router, the execution subject of the above-mentioned method of the embodiment can be HOST (i.e. the main chip end), and the target end is SLAVE wireless transmission module (i.e. the wireless transmission end) at this time. When it is detected that there is target data, the main chip end (HOST) combines multiple target data to obtain a data block, and then sends the data block to the target end (SLAVE wireless transmission module) through the USB channel. After that, the target end sends the data block to the external router through the wireless transmission technology, so as to realize the data transmission function with the external network. Similarly, when the external network sends target data to the smart TV through the router, the execution subject of the above-mentioned method can be SLAVE wireless transmission module (i.e. the wireless transmission end) at this time, and the target end is HOST (i.e. the main chip end). At this time, the SLAVE wireless transmission module combines multiple target data into a data block, and then sends the data block to the target end HOST through the USB channel, so that the target end HOST processes it. In this way, through the above-mentioned interaction process, the communication function between the smart TV and the external network is realized, and the normal video playing effect is realized.

[0078] Based on this, the embodiment provides a data transmission method. Compared with the prior art, in the data transmission process, since the data block contains two or more target data, it can be ensured that when there are two or more target data during data transmission, they do not need to be sent one by one, but can be combined into a data block for transmission at one time, thereby avoiding the problem of low transmission efficiency caused by transmitting a single target data each time when the data amount of the target data is small. The efficiency of data transmission can be improved. At the same time, since the target end includes the main chip end and the wireless transmission end, that is, during the execution of the application, whether the data is transmitted from the main chip end to the wireless transmission end or the data is received by the wireless transmission end and then transmitted to the main chip end, the target data can be combined into a data block for transmission according to the above-mentioned method, so that the problem of slow data transmission between the main chip end and the wireless transmission end can be avoided, thereby improving the efficiency of receiving and transmitting data. In addition, since the transmission data is no longer transmitted one by one, the target end can avoid triggering the receiving event during the process of receiving the target data each time, thereby reducing the number of receiving events that need to be processed by the target end when receiving data, and further reducing the resource occupation and consumption of the target end.

[0079] In some embodiments, the acquiring of the plurality of target data to be transmitted in step 101 of the foregoing embodiments, when executed, can include: when it is determined that there are a plurality of target data, acquiring the plurality of target data based on a preset time period.

[0080] Since some data needs to be guaranteed to be effective during transmission, in this embodiment, the process of acquiring the plurality of target data to be transmitted also needs to consider acquiring according to a preset time period, that is, when there are a plurality of target data, it is necessary to determine which of these target data belong to data that need to be transmitted urgently and acquire such data based on the preset time period set by the user in advance. In this way, when there are a large number of target data, the data that need to be transmitted urgently can be selected based on the preset time period, so as to ensure that when there are a large number of target data, the data that need to be transmitted urgently can be selected based on the preset time period, so as to ensure the timeliness of the data.

[0081] In addition, during the execution of this step, real-time judgment can also be made based on the preset time period to determine whether new target data to be transmitted has appeared, and judgment is made based on the preset time period. When no new target data to be transmitted appears within the preset time period, the target data that have been determined are acquired for subsequent steps to combine data blocks, so as to avoid the problem of affecting timeliness due to waiting for other target data for too long.

[0082] In some embodiments, when it is determined that there are a plurality of target data in the foregoing steps, the plurality of target data are acquired based on a preset time period, which, when executed, can include:

[0083] When the first target data is detected, the timing starts, which is recorded as a starting time;

[0084] determining whether there is a next target data from the starting time to a termination time, wherein the termination time is determined based on the starting time and the preset time period;

[0085] If there is, the timing is restarted until the target data is not detected within the preset time period, and the target data detected within a plurality of preset time periods are acquired.

[0086] In practical applications, target data does not appear all at once but rather sequentially. For example, when the target device is the main chip, the execution entity of the method in this embodiment is the wireless transmission device. In this case, the target data is received by the electronic device from an external source. The target data is transmitted sequentially by other external devices via wireless transmission and acquired one by one by the wireless transmission device. Therefore, according to the method of this embodiment, after detecting data A transmitted from the external source (i.e., the first target data), a timer is started. The current time is 6:21:15 (i.e., the start time). In this example, the preset time period is 1 minute, which determines the end time as 6:22:15. Then, it is determined whether the next target data can be detected between the detection of data A and 6:22:15. If data B is detected during this process, that is, the next target data is detected, and the current time is determined to be 6:22:03, then the timer is restarted, and it is determined whether another target data can be detected between 6:22:03 and 6:23:03 (the new end time). If the target data is not detected again by 6:23:03, it means that no data was sent from the outside after data B was detected. At this time, the detected data A and data B can be retrieved.

[0087] By timing the process after detecting the first target data and determining whether there is another target data between the start and end times based on a preset time period, the system ensures that the timeliness of data transmission is not affected by waiting for subsequent target data. This ensures that the data processed by the main chip can be sent out in a timely manner, or that the external data received by the wireless transmission terminal can be sent to the main chip for processing in a timely manner, so that the data processing process is not affected by the "data waiting" problem.

[0088] In some embodiments, step 102 of the foregoing embodiments, which combines multiple target data according to preset rules to obtain a data block, may include the following during execution:

[0089] Multiple target data sets are combined, and data block header information is added to obtain the data block. The data block header information is used to characterize the number of target data sets contained in the data block, and the attribute information of each target data set; the attribute information includes at least the data length and processing priority.

[0090] Since the data block formed in the process of combining multiple target data needs to be parsed and restored into the original target data for processing in sequence after being transmitted to the target end, in order to ensure successful data parsing, some related information and parameters of the target data need to be added in the process of combining the data block to enable the target end to parse successfully subsequently. The related information and parameters in this step can be understood as the data block header information mentioned above, which not only represents the number of target data in the current data block, but also involves the attribute information of each target data, which indicates the data length of each target data and the processing priority required for subsequent processing. In this way, the target end can parse and split based on the number of target data and the data length of each target data determined in the data block header information after receiving the data block, thereby ensuring the accuracy of restoring the data block into target data. At the same time, the processing priority in the attribute information of each target data can provide a basis for processing which target data first in the target end operation, ensuring the effect of processing urgent data first.

[0091] In some embodiments, in the foregoing step, combining the plurality of target data comprises:

[0092] determining a first transmission limit value, and determining the combination number of the target data when combining the data block based on the first transmission limit value, the first transmission limit value being used to represent the maximum data amount allowed in single transmission;

[0093] combining the target data corresponding to the combination number.

[0094] In the data transmission process, the number of target data selected for combination when the target data is combined into a data block is not unlimited, so the number of target data selected for combination needs to be determined when combining. In this embodiment, the combination number is determined based on the maximum data amount allowed in single transmission of the transmission channel, that is, based on the first transmission limit value.

[0095] Since the combination number is determined based on the maximum data amount allowed in single transmission in this embodiment, it is ensured that the combination number can be selected based on the performance threshold of single transmission of the transmission channel in the data transmission process, thereby avoiding the problem that the combined data block exceeds the maximum data amount allowed in single transmission when the combination number of the target data is too large, avoiding the problem that the data block is too large to cause the transmission process to be split and transmitted again, and ensuring the transmission efficiency.

[0096] In some embodiments, since the first transmission limit value represents the maximum data amount allowed in a single transmission, and the maximum data amount is actually different based on different transmission channels. Based on this, the determination of the first transmission limit value in the foregoing step, and the determination of the combination number of the target data when combining the data blocks based on the first transmission limit value, when executed, can include:

[0097] First, the attribute information of the transmission channel is obtained, and the first transmission limit value of the transmission channel is determined based on the attribute information;

[0098] Then, based on the first transmission limit value and the data amount of the target data, the combination number is determined.

[0099] Since in actual applications, the transmission channels are different, the ways and protocols of transmitting data are also different, for example, the maximum data amount allowed in a single transmission is different between USB channels and PCIE channels.

[0100] Based on this, in the present embodiment, it is necessary to first obtain the attribute information of the transmission channel, and determine the maximum data amount allowed in a single data transmission of the current transmission channel based on the attribute information, that is, the first transmission limit value. In this way, in the manner of determining the combination number based on the first transmission limit value determined by the attribute information of the transmission channel, the size of the data amount of the combined data blocks can be limited from the perspective of the data amount, so as to ensure that the transmitted data blocks can avoid exceeding the first transmission limit, and also ensure that the bandwidth of the transmission channel is utilized as much as possible, and the transmission efficiency is improved.

[0101] In some embodiments, in order to ensure flexible control in the data transmission process, the combination number of the data blocks in the transmission can also be limited based on the user's instruction, that is, the number of target data allowed in a single transmission can also be directly set as the combination number based on the user's instruction.

[0102] Based on this, in the foregoing step, combining the plurality of target data includes:

[0103] Obtaining a second transmission limit value, and determining the second transmission limit value as the combination number, wherein the second transmission limit value is the number of target data allowed in a single transmission based on a preset instruction;

[0104] Combining the target data corresponding to the combination number.

[0105] In this step, the user can set the number of target data allowed for single transmission in advance through preset instructions to obtain a second transmission limit value, and in this case, the second transmission limit value can be directly determined as the combination number in the process of combining target data, so that the user can control the combination number of target data when combining data blocks based on instructions, thereby achieving the effect of flexible control of the transmission process.

[0106] In some embodiments, the combining of the plurality of target data in the foregoing step comprises:

[0107] Obtaining a performance parameter of the target end, the performance parameter being used to represent the number of target data processed simultaneously;

[0108] Determining the combination number according to the performance parameter, and combining the target data corresponding to the combination number.

[0109] As can be known from the embodiment step 101, when the target end is the main chip end, the execution subject of the method of the embodiment is the wireless transmission end, and then in the process of transmitting data to the main chip end, the processing capability of the main chip, that is, the performance parameter, needs to be considered, and then the combination number is determined based on the performance parameter, that is, when the main chip end can process four target data simultaneously, the combination number is four, so that in the process of combining data blocks each time, the processing capability of the main chip end can be used to select an adaptive number of target data for the combination of data blocks, thereby avoiding the problem that the main chip end cannot process the target data combined in excess simultaneously, resulting in data accumulation, and also avoiding the problem that the main chip end cannot fully exert its performance due to too few target data, thereby wasting the processing resources of the main chip end.

[0110] In some embodiments, since the performance of the target end is mainly determined based on the memory thereof, the performance parameter of the main chip end can be determined based on the memory information in the process of determining the performance parameter.

[0111] Based on this, the performance parameter of the target end obtained in the foregoing step comprises:

[0112] Obtaining the memory information of the target end, and determining the performance parameter based on the memory information and the data amount of the target data, the memory information being used to represent the maximum data amount allowed to be processed simultaneously by the main chip end.

[0113] For example, when the target end is the wireless transmission end and the memory information thereof is 1 MB, and when the data amount of the target data is determined to be 100 KB, the performance parameter 10 can be determined based on the method of this step, that is, the number of target data that can be processed simultaneously by the target end is 10.

[0114] Further, as to the above Figure 1In order to achieve the method, another embodiment of the present application further provides a data transmission device. The device embodiment corresponds to the foregoing method embodiment, and for the sake of reading, the details of the foregoing method embodiment will not be described one by one, but it should be clear that the device in the embodiment can correspondingly implement all the contents in the foregoing method embodiment.

[0116] The combination unit 22 can be used to combine a plurality of target data according to a preset rule to obtain a data block, wherein the data block contains two or more target data, and the preset rule can be used to limit the number of target data when combining the data block.

[0117] The sending unit 23 can be used to send the data block to a target end, so that the target end processes the data block, and the target end includes a main chip end and a wireless transmission end.

[0118] Further, as shown, Figure 4 The acquisition unit 21 can be specifically used to acquire a plurality of target data based on a preset time period when it is determined that there are a plurality of target data.
