Abstract
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.
Claims15
An elevator operation control device, comprising:
- 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,
- wherein the component-protective operation control portion prolongs a time from a door-open state to a door-closed state to retard operation of the elevator in restraining the elevator from operating.
An elevator operation control device, comprising:
- 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, wherein the component-protective operation control portion changes an allocation of calls to retard operation of the elevator in restraining the elevator from operating.
An elevator operation control device, comprising:
- a component temperature detecting portion for detecting a temperature of a drive device;
- a component-protective operation control portion for restraining an elevator from operating in accordance with the temperature detected by the component temperature detecting portion;
- and
- a component temperature estimation portion for calculation a tendency of changes in the temperature of the drive device based on information from the component temperature detecting portion, wherein
- the component-protective operation control portion for restrains the elevator from operating in accordance with information from the component temperature estimating portion.
An elevator system, comprising:
- an elevator car;
- an elevator vertical movement control system including at least a drive device which raises and lowers the elevator car including at least a motor, and a controller which controls an operation of the motor which raises and lowers the elevator car;
- a control system which detects a temperature of the drive device and reduces an amount of a vertical movement of the elevator car to prevent an overheating condition while allowing the elevator car to continue to be raised and lowered to a plurality of floors.
