The invention provides a control circuit and a control method of a three-way turnout, the three-way turnout comprises a first turnout and a second turnout, and the control circuit comprises a starting circuit; and a first relay combination circuit comprises a first branch circuit, wherein one end of the first branch circuit is connected to a control negative power supply, and an anti-position action relay excitation coil of the first turnout and a positioning indication relay contact of the second turnout are connected to the first branch circuit in series; wherein when the positioning of the second turnout indicates that the relay is in a suction state, the anti-position action relay of the first turnout is normally driven, the first branch is conducted, and the starting circuit controls a switch motor of the first turnout to execute reverse operation. According to the control circuit and the control method for the three-way turnout, the correctness of control logic of the three-way turnout is remarkably improved, the operation safety of urban rail transit is improved, and the possibility of updating design and equipment is provided for the three-way turnout in an urban rail transit line.

    本发明提供一种三开道岔的控制电路和控制方法,三开道岔包括第一道岔和第二道岔,所述控制电路包括:启动电路;第一继电器组合电路,第一继电器组合电路包括第一支路,第一支路的一端接入控制负电源,第一道岔的反位动作继电器励磁线圈和第二道岔的定位表示继电器接点串联接入第一支路;其中,在第二道岔的定位表示继电器处于吸起状态时,第一道岔的反位动作继电器正常驱动,第一支路导通,启动电路控制第一道岔的转辙电机执行反位操作。本发明提供的三开道岔的控制电路和控制方法,显著提高了三开道岔的控制逻辑的正确性,提高了城市轨道交通的运营的安全性,也为城市轨道交通线路中三开道岔提供了更新设计和设备的可能。
