Abstract: The present disclosure provides a data transmission method, node and system, which belong to the field of computer communication. According to this method, data acquired in real time may be stored in response to detecting interruption of communication with an analysis node. In response to detecting restoration of the communication with the analysis node, real-time data whose storage duration is less than a duration threshold is sent over a first channel, and history data whose storage duration is greater than or equal to the duration threshold is sent over a second channel. The integrity of the data received by the analysis node will not be affected since the data acquired in real time is not lost after detecting interruption of communication with the analysis node. Moreover, since the stored data is simultaneously transmitted to the analysis node over different channels, the efficiency of transmitting data to the analysis node is improved, and the real-time and continuity of the data received by the analysis node is ensured.
