【Abstract】 The paper introduces two kinds of current-collection methods-through pantograph or through collecting shoes and contrasts the advantages and disadvantages of each approach with the working principles of them analyzed. According to the present situation of Guangzhou subway line 4, a control system based on programmable logic controller (PLC) is presented, which can be used to alternate the working mode of subway locomotives between contacting collector and pantograph for collecting current.更多还原
