and the MQ queue publishing module is used for publishing the MQ message after the MQ message of the opposite terminal is acquired from the receiving queue caching module.
6. The data ferry system of claim 5, wherein the data ferry device access module is configured to start a packet cache processing thread after initializing the data ferry device access object, so that the data ferry device access object performs packet cache on data to be sent/received, and specifically includes:
after the data ferry equipment access module initializes the data ferry equipment access object, starting a data packet cache processing thread so that the data ferry equipment access object caches data packets of transmitted/received data;
when the data ferry device access object receives a data receiving success response of the opposite end, removing the data from the data packet cache;
and when the data ferry equipment access object sends the data to the opposite end and does not receive a response within the preset time, retransmitting the data, removing the data from the data packet cache when the retransmission times reach a preset threshold value, and sending a data overtime non-sending reminding event.
7. A data ferry terminal device comprising a processor, a memory and a computer program stored in the memory and configured to be executed by the processor, the memory being coupled to the processor and the processor, when executing the computer program, implementing the data ferry method of any of claims 1 to 4.
8. A computer-readable storage medium, wherein the computer-readable storage medium stores a computer program, and wherein when the computer program is run, the computer program controls an apparatus in which the computer-readable storage medium is located to execute the data ferry method according to any one of claims 1 to 4.
