The invention provides a current collection method and system adaptive to the polarity of a contact network, and the method comprises the steps: recognizing and judging a vehicle driving direction in advance before a vehicle pantograph rises, enabling a vehicle to carry out the adaptive matching adjustment switching of the polarity of a vehicle current collection system in advance according to the polarity of the contact network, and enabling the polarity of the vehicle current collection system to be consistent with the polarity of the contact network; when the pantograph of the vehicle rises, the polarity of the current collection system of the vehicle is matched with the polarity of the overhead line system, current collection and electricity taking are conducted from the overhead line system, the current collection system is used for supplying energy to an electric drive system and supplementing energy to a vehicle-mounted energy storage device, the problem of uncertain contact current collection caused by randomness of the running direction of the vehicle is solved, and the safety of the current collection system of the vehicle is improved.
本发明提供了一种自适应接触网极性的受流方法及系统,本发明在车辆受电弓升弓前,提前识别判断车辆行驶方向,使车辆根据接触网极性提早对车辆受流系统的极性进行自适应匹配调节切换,使车辆受流系统与接触网的极性保持一致;车辆升弓时,车辆受流系统的极性已匹配接触网的极性,从接触网受流取电,用于电驱动系统供能和给车载储能装置进行补能,以解决车辆行驶方向随机性导致的不确定性接触受流问题,提高了车辆受流系统的安全性。
