Embodiment Construction

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0035] See figure 1 , the embodiment of the present invention provides a UART data transmission method, including:

[0036] Step S1, the sending end judges the transmission performance of the sending channel, and marks the sending channel as a normal sending channel or an abnormal sending channel according to the judgment result; optionally, the number of the sending channels is multiple, and more preferably, the The number of sending channels is at least 3; it can ...

Abstract

The invention discloses a UART (Universal Asynchronous Receiver / Transmitter) data transmission method. The method comprises the following steps: a sending end marks a sending channel as a normal sending channel or an abnormal sending channel; the normal sending channel obtains data from the priority buffer area and the normal buffer area in sequence and writes the data into the sending buffer areaso as to send the data to a receiving end; the receiving end performs integrity judgment on the received data, returns feedback information to the sending end, and processes the received data; judging whether the sent data exceeds the maximum retransmission frequency or not when the sending end judges that the data transmission is not successful; if so, transferring to a priority buffer area, andtransmitting by other normal transmitting channels; if not, directly resending the data; and when the sending end judges that the data transmission is successful, starting the transmission of the next frame of data. According to the invention, multiple UART channels are adopted for data distribution and transmission, mutual pressure reduction is realized, and the pressure of data transmission ofeach channel is averaged, so that the average efficiency of data transmission is effectively improved.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to a UART data transmission method. Background technique [0002] With the rapid development of modern technology, people pay more and more attention to big data. People are more sensitive to data transmission efficiency and storage, and require faster and safer transmission methods. Due to irresistible factors such as software and hardware environment and external environment, problems such as data packet loss and data retransmission occur, resulting in unsatisfactory average transmission efficiency. For software and hardware that transmit large data and require high real-time data, this is not a problem. good thing. [0003] In the prior art, when the UART serial port has data packet loss during the transmission process, the data receiver needs to notify the sender to resend the data, and the average transmission efficiency is not very high due to resending packet loss...
