An ABS brake control circuit of an elevator brake system comprises a brake controller, a backup power supply, a manual rescue instruction circuit, a power grid power-off instruction circuit, a system failure instruction circuit, a signal identification circuit and a brake mode switching circuit. when transport equipments, such as an elevator, an escalator, and so on, encounters a system failure or power grid power-off or needs an emergency rescue, the ABS brake control circuit can allow the transport equipment to transition to a safe brake stop through a previous safe deceleration, thereby eliminating a significant security risk caused by a halt resulted from one-step brake which exists in an elevator brake system, and being capable of ensuring that the manual brake releasing will not cause the phenomena of a stalling of an elevator car and a brake failure of a brake, such that the brake safety of the transport equipments such as an elevator, an escalator, a moving walkway and the like is increased.
