Embodiment Construction

[0043] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0044] refer to figure 1 , shows a structural block diagram of an elevator braking control device according to an embodiment of the present invention. The elevator brake control device includes: a safety brake power supply circuit 110 , a brake control circuit 120 and an elevator host 130 . Wherein, one end of the brake control circuit 120 is connected to the power output end of the safety brake power supply circuit 110 , and the other end of the brake control circuit 120 is connected to the brake of the elevator...

Abstract

The invention discloses an elevator brake control device and method. The elevator brake control device comprises: a safety band-type brake power supply circuit, a band-type brake control circuit and an elevator host; one end of the band-type brake control circuit is connected with the power output end of the safety band-type brake power supply circuit, and the other end of the band-type brake control circuit is connected with a brake of the elevator host; the safety band-type brake power supply circuit is used for outputting a power supply signal to the band-type brake control circuit according to a power supply enable signal so as to supply power for the band-type brake control circuit; the band-type brake control circuit is used for generating current according to a band-type brake control enable signal and the power supply signal output by the safety band-type brake power supply circuit, so that the brake is in a release state, and a corresponding control fault signal can be fed back to an elevator main control system when a short-circuit fault is detected, so as to trigger the output of a turn-off enable signal of the elevator main control system so that the brake is in a release state. According to the elevator brake control device, the problem can be solved that the on-off control of the existing motor and brake loop depends on the contactor in the elevator, thereby improving the flexibility of the brake control of the elevator.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of elevators, in particular to an elevator braking control device and method. Background technique [0002] Usually, the normal stop or emergency stop of the elevator is realized by disconnecting the motor and brake circuit. Specifically, when the power supply of the motor is disconnected or the driving waveform is canceled, the motor stops running, the brake circuit is disconnected, and the power supply braking function is activated, that is, when the brake circuit is powered off, the electromagnetic force disappears, and under the action of spring force pressure The shoe part quickly presses against the braking surface to form a brake that keeps the motor in a braking state. It can be seen that the stopping of the motor and the closing of the brake jointly ensure the safety of the elevator when it stops. [0003] At present, cutting off the power supply of the motor and the brak...
