Abstract

The invention discloses a self-adaptive calculation method for a full-speed closely-attaching running control curve of a rail transit train. The method includes the following steps that a train running path and a train full-speed running reference curve are determined; a train traction running curve is calculated; the intersection sections of the train traction running curve and other reference curves are calculated; a train cruising running curve is calculated; the intersection sections of the train cruising running curve and other reference curves are calculated; a train braking running curve is calculated; the intersection sections of the train braking running curve and other reference curves are calculated; and in the train running direction, the train full-speed closely-attaching running control curve is generated. By the adoption of the method, a project task period can be greatly shortened, the project construction schedule is accelerated, and a large amount of expenditure is saved; and the use period of train-mounted system equipment is prolonged, the repair and maintenance workloads are reduced, the comprehensive design quality and level of a rail transit project are improved, and effective realization of the line transportation capacity is guaranteed.

Description

technical field [0001] The invention relates to an adaptive calculation method for a full-speed close-fitting operation control curve of a rail transit train, in particular to an adaptive calculation method for a full-speed close-fitting operation control curve of a train used in a rail transit train operation control system. Background technique [0002] The full-speed close-fitting operation control curve of the rail transit train operation control system is regarded as the train operation curve with the highest operating efficiency. The basis of scheme design, etc., is one of the key factors influencing the comprehensive service level of rail transit operation. [0003] The full-speed tight running control curve of rail transit trains is composed of train traction running curve, cruising running curve and braking running curve. According to the reference curve of train running at full speed (no train traction operation reference curve) obtained in advance budget, referri...
