The invention discloses a subway return rail switching method and system adopting a double-return-rail system, and particularly relates to the field of return rail control. The subway return rail switching system comprises a control end, a change-over switch box, a grounding carbon brush and a return device; a decision judgment device is further arranged in a control carriage, wherein the controlend outputs a rail position switching signal; the decision judgment device judges the state of a train and outputs the rail position switching signal to the change-over switch box according to the judgment result; and the change-over switch box controls the train to return back from the return device through a walking rail after inputting a walking rail switching signal for a third preset time, and controls the train to return from the grounding carbon brush through a special rail after inputting a special rail switching signal for the third preset time. By judging the train condition, the subway train can switch the return rails under the safe and error-free condition, and the technology of controlling the return rails under a double-return-rail system in the prior art is perfected.
本发明公开了一种采用双回流轨系统的地铁回流轨切换方法与系统,具体涉及回流轨控制领域,包括控制端、转换开关箱、接地碳刷和回流器,控制车厢中还设有决策判断器,其中:控制端输出轨位切换信号;决策判断器判断列车状态,并根据判断结果将轨位切换信号输出至转换开关箱;转换开关箱在输入走行轨切换信号第三预设时间后,控制列车由回流器通过走行轨回流,并在输入专用轨切换信号第三预设时间后,控制列车由接地碳刷通过专用轨回流。本发明通过对列车车况的判断,使得地铁列车能够在安全、无误的情况下进行回流轨的切换,完善了现有技术在双回流轨系统下对回流轨控制的技术。
