The invention relates to an elevator brake control method and device, elevator control equipment and an elevator. The elevator brake control method comprises the following steps: when the rotating speed of the host machine of the elevator is not consistent with the operating speed of the elevator car, the static friction force between a hanging device and the host machine of the elevator is obtained according to the load capacity and the first set specification parameter of the elevator car; the first set specification parameter comprises the empty weight and the counter weight of the elevatorcar and the friction coefficient between the hanging device and the host machine of the elevator; according to the specification parameter of the static friction force and a brake, the target coil current value of the brake is obtained; when the braking torque of the brake is equal to the static friction force, the target coil current value is the coil current value of the brake; the coil currentvalue of the brake is adjusted to be the target coil current value, the elevator car is braked. When the rotating speed of the host machine of the elevator is not consistent with the operating speedof the elevator car, the current of the brake is adjusted to enable the braking torque to be equal to the static friction force and effectively improve the control efficiency of elevator braking.
Description
technical field [0001] The present application relates to the technical field of electrical equipment, in particular to an elevator braking control method and device, elevator control equipment and an elevator. Background technique [0002] With the continuous development of electrical equipment technology, the elevator has also made continuous progress in the application range and technical realization, and the safety, reliability and comfort have been greatly improved. At present, during the daily operation of the elevator, when an emergency and dangerous condition occurs (such as the safety circuit of the elevator is disconnected), the control system of the elevator will disconnect the electrical connection between the brake and the drive module of the brake, so that the brake is in a power-off state. state, and immediately stop the host. After the main engine stops rotating, due to the inertia of the car and the counterweight, the suspension device will slip on the trac...
