Detailed Description
in order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
in the embodiment of the invention, the original data in the original data packet is acquired and split into N data strings, the N data strings are sent to the buffer according to the sequence, and after the data strings received by the buffer are sent, the next data string is sent to the buffer.
in order to explain the technical means of the present invention, the following description will be given by way of specific examples.
the first embodiment is as follows:
Fig. 1 is a flowchart illustrating a packet processing method according to a first embodiment of the present invention, which is detailed as follows:
step S11, obtaining the original data in the original data packet, and splitting the original data into N data strings, where N is an integer and is greater than or equal to 1.
when there are a plurality of buffers, in order to balance the use of the buffers and avoid excessive use of any one of the buffers, the step S11 specifically includes:
A1, the number of acquisition buffers and the original data in the original data packet.
And A2, when the number of the buffers is N, splitting the original data in the original data packet into N data strings.
specifically, the original data in the original data packet is obtained, the number of buffers is obtained, and when the number of the buffers is N, the original data in the original data packet is split into N data strings according to the number of the buffers. It should be noted that the size of the split N-segment data string is smaller than the maximum capacity of the buffer. In general, when there are a plurality of buffers, the maximum capacity is equal, and at this time, the original data may be divided into N data strings of equal byte size, but if the bytes of the original data are not enough to divide the N data strings of equal byte size equally, the original data is first divided into N-1 data strings of equal byte size, and the remaining bytes are regarded as the nth data string. For example, the original data is split into a data string of 3(N ═ 3) segments with a byte size of 8 bytes. Of course, if the remaining data string is less than 8 bytes after splitting the 2-byte data string having a byte size of 8 bytes, the remaining bytes will be the 3 rd-stage data string.
Optionally, when there is only one buffer, in order to avoid that the size of the data string sent to the buffer exceeds the maximum capacity of the buffer, the step S11 specifically includes:
A1', obtaining the capacity of the buffer and the original data in the original data packet;
A2', splitting the original data in the original data packet into N data strings, so that the size of the split data strings is smaller than or equal to the capacity of the buffer. Specifically, whether the size of the original data exceeds the maximum capacity of a buffer is judged, and when the size of the original data exceeds the maximum capacity of the buffer, the original data in the original data packet is split into N data strings, so that the size of each split data string is smaller than or equal to the capacity of the buffer.
And step S12, sending the N data strings to a buffer according to the sequence.
Specifically, after splitting the original data in the obtained original data packet into N data strings according to the number or capacity of the buffer, the N data strings are sent to the buffer according to the sequence of the original data, for example, the 1 st data string is sent to the buffer first, and then the 2 nd data string is sent.
Optionally, in order to ensure that the split data strings are sent in sequence, before the S12, the method includes:
And B0, marking the split data strings into N sections according to the sequence of the original data.
Specifically, after the original data in the obtained original data packet is divided into N data strings according to the number or capacity of the buffer, the N data strings are labeled from small to large according to the sequence of the original data, and at this time, step S12 sequentially sends the N data strings to the buffer according to the labels from small to large.
optionally, when the number of buffers is N, in order to ensure that the split data strings are sent in sequence, the S12 includes:
b1, configuring the priority of the N buffers.
B2, setting a one-to-one correspondence according to the sequence of the data strings and the high and low priorities of the buffers, and sending the N sections of data strings to the corresponding buffers according to the correspondence.
Specifically, the data string ranked at 1 is set to correspond to the buffer with the highest priority, the data string ranked at 2 is set to correspond to the buffer with the second highest priority, and the rest are analogized in sequence. Since the higher the priority of the buffer is, the earlier the sequence of transmitting the data strings is, the priority transmission of the data strings in the front is guaranteed.
step S13, after the data string received by the buffer is sent, the next data string is sent to the buffer.
Specifically, after the data string received by the buffer is confirmed to be sent, the next segment of data is sent to the buffer, so that the data string can be guaranteed to be completely sent, and a receiver can be guaranteed to receive the complete data string.
in order to further confirm that the data string received by the buffer has been sent, the step S13 specifically includes:
And C1, reading a preset sending flag bit, and judging whether the data string received by the buffer is sent completely according to the sending flag bit.
And C2, after the data string received by the buffer is completely sent, sending the next segment of data string to the buffer.
Specifically, after the data string received by the buffer is sent, a preset sending flag bit is read, and whether the received data string is sent or not is judged according to the sending flag bit. And when the preset sending flag bit is read to indicate that the data string received by the buffer is completely sent, sending the next segment of data string to the buffer. And when a preset sending flag bit is read to indicate that the data string received by the buffer is not sent completely, continuing to wait for sending the next segment of data string to the buffer.
Further, the C1 specifically includes:
and C11, reading a preset sending flag bit, and judging that the data string received by the buffer is sent completely when the sending flag bit is a first preset value. For example, the first preset value may be set to 1.
and C12, when the sending flag bit is a second preset value, determining that the sending of the data string received by the buffer is not completed, where the second preset value is not equal to the first preset value. For example, the second preset value may be set to 0.
correspondingly, after the data string received by the buffer is completely sent, before the next data string is sent to the buffer, the method includes:
and C13, resetting the sending flag bit from the first preset value to the second preset value.
specifically, after the data string received by the buffer is sent, a preset sending flag bit is read, when the sending flag bit is a second preset value, it is determined that the received data string is not sent completely, the next data string is continuously sent to the buffer, when the sending flag bit is a first preset value, it is determined that the data string received by the buffer is sent completely, the sending flag bit is reset from the first preset value to a second preset value, and then the next data string is sent to the buffer.
Optionally, in order to improve the transmission efficiency and avoid invalid waiting, after the end of transmitting the data string received by the buffer, before transmitting the next segment of data string to the buffer, the method further includes:
And D1, when the data string received by the buffer is judged not to be completely transmitted and the next data string is continuously transmitted, acquiring the transmission time of the data string received by the buffer.
and D2, when the sending time is larger than or equal to a preset time threshold, restarting to send the data string received by the buffer. It should be noted that, when restarting transmission of a data string received by the buffer, since the buffer may have stored part of the data string at the last reception, in order to avoid the buffer storing an erroneous data string, when the buffer receives the first data of a new data string, if it is determined that the buffer has stored data, the data stored in the buffer is overwritten with the newly received data string.
D3, when the number of times of restarting and sending the data string received by the buffer is larger than the preset number of times, prompting that the sending is failed.
specifically, when the read preset sending flag bit is a second preset value and it is determined that the sending of the received data string is not completed, obtaining sending time for sending the data string received by the buffer, and when the sending time is smaller than a preset time threshold, continuing to wait for the end of the sending; and restarting to transmit the data string received by the buffer when the transmission time is greater than or equal to a preset time threshold.
specifically, taking an application scenario as an example, after the controller receives the data packets, the number of the acquired buffers is 3, the controller splits the original data of the can data packet into 3 data strings according to the number of the buffers, configures the priorities of the 3 buffers according to the sequence of the 3 data strings, stores the data string 1 with the highest sequence in the buffer 1 with the highest priority, and starts to send the data string 1. Before sending the data string 2 to the buffer 2, the controller reads a preset sending flag bit, when the sending flag bit is 1, the data string 1 received by the buffer 1 is judged to be sent completely, the controller resets the sending flag bit to 0, then the data string 2 is sent to the buffer 2, and the sending of the data string 2 is started; if the preset transmission flag bit is read to be 0 before the data string 2 is transmitted to the buffer 2, it is determined that the data string 1 received by the buffer 1 has not been transmitted. Acquiring the sending time of the sending data string 1, and when the sending time is greater than or equal to a preset time threshold value, restarting the sending data string 1 received by the sending buffer 1 before sending the data string 2 to the buffer 2 by the controller. When the number of times of restarting the data string 1 received by the transmission buffer 1 is larger than a preset number of times, a transmission failure is prompted.
In the first embodiment of the present invention, original data in an original data packet is obtained and split into N data strings, the N data strings are sequentially sent to a buffer, after the sending of the data string received by the buffer is completed, a sending flag is read, when the sending flag is a first preset value, it is determined that the sending of the received data string is completed, and then the next data string is sent to the buffer. When the sending flag bit is a second preset value, the received data string is judged not to be sent completely, and the next data string continues to wait for sending, so that the completion of orderly sending of each data string is ensured, and the accuracy of data sending is improved.
it should be understood that, in the embodiment of the present invention, the sequence numbers of the above-mentioned processes do not mean the execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiment of the present invention.

In general, when there are a plurality of buffers, the maximum capacity is equal, and at this time, the original data may be divided into N data strings of equal byte size, but if the bytes of the original data are not enough to divide the N data strings of equal byte size equally, the original data is first divided into N-1 data strings of equal byte size, and the remaining bytes are regarded as the nth data string. For example, the original data is split into a data string of 3(N ═ 3) segments with a byte size of 8 bytes.
