The invention discloses a data communication method, device and system and a storage medium, and relates to the technical field of Ethernet communication, and the data communication method comprises the steps: firstly obtaining a plurality of data packets generated by an upper-layer application, and then constructing corresponding communication sub-packets according to the data length, the content and the check code of the data packets; and extracting a standard Ethernet frame header, inserting a combined identification field, splicing the communication sub-packets to the identification field in sequence, adding a frame verification sequence to generate a combined packet, and sending the combined packet to a receiving end. And the receiving end executes first integrity check through the frame check sequence, splits the communication sub-packets according to the merging identifier after the first integrity check passes, and executes second integrity check through the communication sub-packet check code to process the effective communication sub-packets. According to the invention, the redundancy overhead is reduced through merging and packaging of multiple small data packets, the equipment compatibility is guaranteed by the standard frame header, the anti-error-code capability is improved through double-layer verification, and the transmission efficiency and the anti-error-code performance of the small data packets can be optimized while the compatibility is considered.

The invention relates to the technical field of short-wave communication, and provides an acoustic codeword encoding and decoding method, device and equipment and a storage medium, and the method comprises the steps: receiving a data frame of acoustic codeword data transmitted by a transmitting end; the data frame at least comprises a vocoder data field and a frame mark word field, the frame mark word field comprises effective elements, and the number of the effective elements is used for judging whether the data frame is an end frame or not; determining whether the data frame is an end frame or not according to a preset threshold value of an effective element corresponding to the vocoder data; and when the data frame is an end frame, decoding the end frame and all data frames before the end frame to obtain target pulse code modulation (PCM) voice data. According to the method provided by the invention, the data frame of the vocoder data with the effective elements sent by the sending end is received, and the vocoder data is decoded to obtain the target pulse code modulation (PCM) voice data, so that the error code resistance and the reliability of data detection in the short-wave low-speed vocoder data transmission process are improved.
