Intelligent train set linkage control method and system based on green wave signals

The invention relates to an intelligent train set linkage control method based on a green wave signal. The method comprises the steps that the arrival time of a train set driving to a first intersection is determined based on the preset departure time of the train set and the required time length of driving to the first intersection; acquiring a green wave coordination period starting moment of the first intersection; determining a formal departure moment based on the arrival moment and the green wave coordination period starting moment; wherein the step of determining the official departure moment comprises the following steps: acquiring a first difference value between the arrival moment and the starting moment of a green wave coordination period, and judging whether the first difference value belongs to a preset first threshold range or not; when it is judged that the first difference value belongs to the first threshold range, the preset departure moment is determined as the formal departure moment; when
