the arrival time interval calculation module is specifically configured to acquire a preceding train of the train according to the train sequence relation chain through an ATC of the train, query current train information of a stored line according to the preceding train, acquire train number, position and speed information of the preceding train, and calculate arrival time of the preceding train passing through a certain switch node in the throat area.
And the ATC of the train also calculates the arrival time of the train passing through a certain turnout node in the throat area according to the position and the speed of the train.
And the ATC of the train calculates the arrival time interval between the train and the preceding train according to the arrival time of the train and the preceding train passing through a certain turnout node in the throat area.
10. The method of claim 9, wherein:
the passing time interval adjusting module is specifically configured to subtract a passing interval specified in the planned operation diagram from an arrival time interval between the local train and a preceding train by using an ATC of the train to obtain a difference value;
when the difference value is larger than zero, setting the recommended speed of the train to be larger than the current train speed, adjusting the running process of the train by the ATC of the train according to the recommended speed, and compressing the arrival time interval between the train and the preceding train until the difference value disappears or is within a specified numerical range;
and when the difference value is smaller than zero, setting the recommended speed of the train to be smaller than the current train speed, adjusting the running process of the train by the ATC of the train according to the recommended speed, and increasing the arrival time interval between the train and the preceding train until the difference value disappears or is within a specified numerical range.
