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.
Description
technical field [0001] The invention relates to the technical field of urban rail transit, in particular to a control circuit and a control method for a three-way turnout. Background technique [0002] With the continuous increase in the demand for operating scenarios, more and more three-way turnouts are used in urban rail transit. The existing three-way turnout control method only involves control based on software algorithms, but the current circuit design cannot fully meet the control requirements of the three-way turnout, and cannot achieve the display consistency of the three-way turnout. Contents of the invention [0003] The invention provides a control circuit and a control method of a three-way turnout, which are used to solve the defect that the circuit design in the prior art cannot fully meet the control requirements of the three-way turnout. [0004] The present invention provides a control circuit for a three-way turnout, the three-way turnout includes a fi...
