For specific limitations of the elevator brake control system, reference may be made to the above limitations on the elevator brake control parameter generation method, and details are not described here.
In one embodiment, to facilitate understanding of embodiments of the present application by those skilled in the art, reference will now be made to the specific examples illustrated in the drawings. Referring to fig. 6, a circuit connection schematic diagram of an elevator brake control method is shown, wherein the circuit connection schematic diagram comprises: elevator control equipment, band-type brake controller and elevator band-type brake equipment.
Wherein, band-type brake controller includes: the brake power supply, first contactor, second contactor, first current sensor and second current sensor.
Wherein, elevator band-type brake equipment includes: first elevator band-type brake and second elevator band-type brake.
The first contactor is controlled by the elevator control equipment to perform pull-in or pull-out actions so as to control connection or disconnection of a circuit where the first elevator band-type brake is located. The first current sensor is used for collecting a coil current value of the first elevator brake and feeding the collected coil current value back to the elevator control equipment.
The second contactor is controlled by the elevator control equipment to perform pull-in or pull-out action so as to control connection or disconnection of a circuit where the second elevator band-type brake is located. The second current sensor is used for collecting the coil current value of the second elevator brake and feeding the collected coil current value back to the elevator control equipment.
Fig. 7 shows a starting flow chart of an elevator brake in an elevator brake control method, and the main steps of the control method for starting the elevator brake include: the elevator control equipment sends a first band-type brake starting instruction to control the first contactor to suck, and the band-type brake power supply outputs current required by starting the first elevator band-type brake; when the first elevator brake is started, the elevator control equipment controls the brake power supply to output the current required by the first elevator brake to be kept open, and sends a second brake starting instruction to control the second contactor to be closed, so that the brake power supply outputs the current required by the first elevator brake to be kept open and the second elevator brake to be started; when the second elevator band-type brake is started, the band-type brake power supply is controlled to output the current required by opening the first elevator band-type brake and the second elevator band-type brake simultaneously.
Fig. 8 shows a release flow chart of an elevator brake control method, and the main steps of the control method for releasing the elevator brake comprise: the elevator control equipment sends a first band-type brake release instruction to the band-type brake power supply, so that the output power of the band-type brake power supply is reduced, and meanwhile, the first contactor is controlled to be disconnected. After the first contactor is disconnected, the current output to the first elevator brake begins to be reduced, the elevator control equipment obtains the coil current of the first elevator brake through the current sensor, and when the coil current of the first elevator brake suddenly rises, the elevator control equipment judges that the first elevator brake generates the maximum release noise. And the elevator control equipment sends a second band-type brake release instruction to the band-type brake power supply so as to reduce the output power of the band-type brake power supply, and simultaneously controls the second contactor to be disconnected until the coil currents of the first elevator band-type brake and the second elevator band-type brake are reduced to zero, and the first elevator band-type brake and the second elevator band-type brake are released completely.

In this embodiment, start through the order of control elevator band-type brake equipment, can reduce the starting power of elevator band-type brake to through staggering the biggest time of two elevator starting noises, effectively reduce the starting noise that two elevator band-type brakes started simultaneously. Through the sequential release of control elevator band-type brake equipment, when first elevator band-type brake release noise is the biggest, release second elevator band-type brake, with the release noise maximum time stagger, effectively reduce the release noise that two elevator band-type brakes released simultaneously.
