The present application relates to an elevator braking control method, device, elevator control equipment, and elevator. The aforementioned method includes: when the rotation speed of the elevator host is inconsistent with the running speed of the car, according to the load capacity of the car and the first set specification Parameters to obtain the static friction torque between the suspension device and the elevator main machine; the first set specification parameters include the no-load weight of the car, the weight of the counterweight, the friction coefficient between the suspension device and the elevator main machine; according to the static friction torque and the specifications of the brake Parameters to get the target coil current value of the brake; the target coil current value is the coil current value of the brake when the braking torque of the brake is equal to the static friction torque; adjust the coil current value of the brake to the target coil current value to brake the car. By adjusting the current of the brake when the rotation speed of the main engine of the elevator is inconsistent with the running speed of the car, the braking torque is equal to the static friction torque, which effectively improves the braking control efficiency of the elevator.
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...
