Method and system for transmitting vehicle-mounted video data

The embodiment of the invention discloses a method and system for transmitting vehicle-mounted video data. The method comprises the steps: enabling an updated historical video list to be transmitted to a terminal, wherein the historical video list comprises a transmitted video list and a video list which is not transmitted; receiving a program request command sent by the terminal; inquiring the corresponding historical video data from stored data according to the query condition contained in the program request command, and transmitting the program request command to the terminal. Through the above method of sending the program request command and inquiring the corresponding historical video data from stored data according to the query condition contained in the program request command, the targeted historical video data can be obtained in a non-transmission time, thereby bringing convenience to a ground worker for knowing the condition of a haulage motor, reducing the potential safety hazards of the haulage motor in a running process, and enabling the solutions for the ground worker to solve vehicle equipment problems to be diversified.
