摘要:
In an elevator operation control device, a plurality of operation control profiles for prescribing values regarding operation of an elevator, for example, a speed of a car are registered in an operation control device body. The operation control device body collects values such as the activation frequency of the car and the like as information on a condition of use of the elevator. The operation control device body also selects one of the operation control profiles in accordance with the information on the condition of use, and controls the operation of the elevator based on the selected operation control profile.

An elevator operation control device has a component temperature detecting portion for detecting a temperature of a drive device, and a component-protective operation control portion for restraining an elevator from operating in accordance with the temperature detected by the component temperature detecting portion. Upon detecting a rise in the temperature of the drive device, the component-protective operation control portion changes operation control parameters of the elevator to restrain the elevator from operating and thus stops the rise in the temperature of the drive device before a protection circuit stops the elevator from operating.

In an elevator apparatus, a rescue operation for a car is performed by a rescue operation controller. The rescue operation controller obtains a rescue operation voltage value and applies a voltage having the rescue operation voltage value to a brake coil in response to a signal from a speed detector at a time of the rescue operation for the car. The rescue operation voltage value is a value of the voltage necessary to reduce braking force of a brake device to move the car by using a state of imbalance between the car and a counterweight.

In an elevator apparatus, a brake control device has a first brake control portion for operating a brake device upon detection of an abnormality to stop a car as an emergency measure, and a second brake control portion for reducing a braking force of the brake device when a degree of deceleration of the car becomes equal to or higher than a predetermined value at a time of emergency braking operation of the first brake control portion. The second brake control portion detects emergency braking operation of the brake device independently of the first brake control portion.

In an elevator apparatus, a brake device is controlled by a brake control device. The brake control device has a first brake control portion for operating the brake device to stop a car as an emergency measure upon detection of an abnormality, and a second brake control portion for reducing a braking force of the brake device when a deceleration of the car becomes equal to or larger than a predetermined value during emergency braking operation of the first brake control portion. The second brake control portion controls the brake device independently of the first brake control portion.
摘要:
In an elevator apparatus, a brake device stops a car from running. The brake device can adjust the magnitude of part of a total braking force generated at a time of emergency braking of the car. As an example of the brake device, the brake device has a nonadjustable brake portion for immediately generating a braking force without making an adjustment thereof at the time of emergency braking of the car, and an adjustable brake portion for generating a braking force while making an adjustment thereof at the time of emergency braking of the car.
摘要:
In an elevator apparatus, a brake device for braking the running of a car is controlled by a brake control device. The brake control device monitors a speed of the car and a degree of deceleration of the car at a time of emergency braking of the car. When the degree of deceleration of the car reaches a preset target deceleration, the brake control device generates a target speed pattern for decelerating the car from a speed of the car at that time.
