摘要：
Circuits and methods for controlling an elevator braking system are provided. A circuit for controlling an elevator braking system includes a contracting brake signal generating circuit, wherein a door lock relay DJ and a contracting brake contractor ZJ are series connected; a contracting brake signal processing circuit, for converting between high and low level to trigger a braking controller; and an isolation control switch CK jointly connected in the contracting brake signal generating circuit and the contracting brake signal processing circuit.
