A multi-terminal data interaction system based on rail transit, characterized in that, When the interactive terminal does not receive the interactive data returned by the receiving terminal within a preset time range, abnormal information is returned to the cloud and the independent terminal. The application relates to a data transmission method and device. The method comprises the following steps: A data acquisition module acquires rail transit data through an independent terminal; A data backup module transmits the data to a cloud backup; A data transmission module transmits the data to an interactive terminal, the interactive terminal identifies the data and generates an identification code, and then the data is transmitted to a receiving terminal; A data interaction module acquires the data through the receiving terminal and returns interactive data; The first data recognition and sending module recognizes the interactive data through the interactive terminal and sends the data to the cloud. The second data recognition and sending module recognizes the interactive data through the cloud and returns the data to the independent terminal. After obtaining the data through the independent terminal, the data is saved in the local server. The local server generates an identification code for the data according to the type and specific content of the data. Subsequently, the corresponding data is retrieved according to the identification code. The recognition code generated when the interactive terminal recognizes the data is uploaded to the cloud. The cloud retrieves relevant data for comparison according to the data recognition information of the recognition code, confirms whether the data is complete and accurate, and if so, divides the priority of the recognition code of the data according to the content and type of the data. After obtaining the data, the receiving terminal recognizes the data, calls relevant data from the cloud for comparison, confirms whether the data is complete and accurate, and if so, the receiving terminal generates corresponding interactive data according to the obtained data and transmits the data. Before returning the interactive data, the receiving terminal stores the interactive data locally. If not, the receiving terminal calls the locally stored data for transmission. When the cloud recognizes and determines that the interactive data is normal, the cloud backs up the interactive data to the cloud database, generates an independent identification number for the interactive data, and returns the interactive data to the corresponding independent terminal. When the cloud determines that the interactive data is abnormal, the cloud stops returning the interactive data, transmits the interactive data and abnormal information to the interactive terminal, and the interactive terminal compares the interactive data returned by the cloud and the interactive data returned by the receiving terminal. If the judgment result is consistent, the interactive data is transmitted to the receiving terminal again to confirm with the locally stored interactive data of the receiving terminal.
