Redundant data interaction method, device and equipment and electronic medium

The invention discloses a redundant data interaction method. The method comprises the following steps: sending interaction data to a redundant card; receiving interaction data sent by the redundant card; and judging whether the interaction data is staggered or not, and if the interaction data is staggered, adjusting the execution time of the receiving task in the scheduling period according to the offset of the data staggering. When the redundant card is subjected to hot restart, whether interactive data dislocation occurs or not is judged by detecting the interactive data, and the execution time of receiving tasks in the redundant interaction is adjusted in the next task scheduling period according to the offset of the data dislocation, so that the redundant interaction of the card can always receive a complete data packet, and the situation that the redundant data is misaligned due to the interactive data dislocation is avoided. Therefore, false alarm of the system is avoided, and the reliability of the sys
