Patent ID: 8118140

Claim:
An elevator system, comprising: an elevator control system, for implementing controlled movement of the elevator car; a door mechanism control system, for implementing controlled movement of the elevator car door; a door coupler, for forming a mechanical coupling between elevator car door and landing door; and a controller of fast start of travel, said controller having: an input for elevator car position data; an input for landing door position data; an input for car door position data; and at least one output for activating the elevator motor power supply circuit and the elevator brake release circuit, wherein between the elevator control system, the fast start controller and the door mechanism control system, a communication bus is provided, the elevator control system is configured to send to the door mechanism control system a request for closing the elevator car door, and in connection with this a fast start request to the fast start controller, the fast start controller being configured to determine the progress of fast starting on the basis of elevator car position data, landing door position data and car door position data, the fast start controller is configured to send, after the elevator car door has been closed, an activation signal for activating the elevator motor power supply circuit and the elevator brake release circuit, the elevator control system is configured to allow current to be passed through the activated elevator motor power supply circuit to the elevator motor so as to keep the elevator car immovable in the elevator shaft, the elevator control system is configured to release the elevator brake by controlling the activated brake release circuit, and the fast start controller is configured to send to the elevator control system, after the landing door has been closed, a permission to start travel of the elevator.
