Time division control train energy-saving operation method and device

Abstract

The invention provides a time-division-control train energy-saving operation method and device. The time-division-control train energy-saving operation method comprises the steps that a target route section, between adjacent platforms, of a train is determined; based on the target route section, determining a ceiling speed curve and a target speed curve of the train running in the target route section; based on the ceiling speed curve and the target speed curve, a target coasting interval is determined from the target route section, and the target coasting interval corresponds to a target coasting threshold value; and based on the target coasting interval, the ceiling speed curve and the target speed curve, a target control instruction used for controlling the running state of the train is generated. According to the time division control train energy-saving operation method, the train speed can be globally and dynamically planned, the adaptability is high, the calculation amount is small, the calculation precision is high, the smoothness is high, and the generation efficiency of the train energy-saving operation speed curve is effectively improved; and energy consumption can be effectively reduced, and both energy conservation and punctual operation are achieved.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, in particular to a time-division controlled train energy-saving operation method and device. Background technique [0002] Rail transit plays an increasingly important role in public travel. In order to meet the current fast-paced social environment, it is extremely important to ensure that trains arrive on time. However, with the surge in rail transit traffic, the total energy consumption of urban rail transit systems also soaring year by year. In the related art, the operating conditions of the train are mainly controlled by the comparison table method and the optimal solution method. However, the comparison table method makes the operation speed prone to periodic jumps, and consumes a large amount of energy; the optimal solution method generates The running speed curve cannot be changed based on the actual situation, so that the running speed curve is not the optimal energy saving ...
