Data transmission method, device and system based on intelligent traffic, and storage medium

The invention provides a data transmission method, a device and a system based on intelligent traffic, and a storage medium. The method comprises the steps of acquiring working state information of anintelligent vehicle-mounted network terminal in a vehicle at the current moment; judging whether the working state information meets a preset transmission state condition; if the working state information does not meet the preset transmission state condition, storing the position information acquired by the intelligent vehicle-mounted network terminal at the current moment; and if the working state information meets the preset transmission state condition, respectively sending the position information acquired by the intelligent vehicle-mounted network terminal at the current moment and the position information stored at the previous moment to a back-end server. The state of the intelligent vehicle-mounted network terminal can be judged, the actual situation of the current intelligent vehicle-mounted network term
