An ABS brake control circuit of an elevator brake system, comprising a brake controller, a backup power supply, a manual rescue instruction circuit, a power grid power-off instruction circuit, a system breakdown instruction circuit, a signal identification circuit and a braking mode switching circuit. When transport equipment, such as an elevator, an escalator and the like, suffers from system breakdown or power grid power-off or needs an emergency rescue, the ABS brake control circuit can allow the transport equipment to make the transition to a safe braking stop through a previous safe speed reduction, so as to eliminate a major potential safety hazard caused by stopping by one-step braking which exists in an elevator brake system, and be capable of ensuring that the manual release of brake will not cause the phenomena of the stalling of an elevator car and the braking failure of a brake device, thereby increasing the braking safety of transport equipment such as an elevator, an escalator, a moving walkway and the like. |
