The invention discloses an elevator band-type brake control circuit and an elevator. The elevator band-type brake control circuit comprises a safety control module, a power conversion circuit and a microprocessor. The controlled end of the safety control module is connected into an elevator safety loop, the input end of the safety control module is connected with the microprocessor, and the output end of the safety control module is connected with the controlled end of the power conversion circuit. Wherein the microprocessor is used for outputting a control signal to the safety control module; the safety control module is used for switching on or switching off electric connection between the microprocessor and the power conversion circuit according to an output signal of the elevator safety circuit; and the power conversion circuit is used for supplying power to an elevator braking component according to the control signal. A band-type brake contactor is omitted, and the elevator stopping and people trapping condition and action noise of the band-type brake contactor caused by abnormity of the band-type brake contactor are avoided.
