Elevator operation control device which controls the elevator based on a sensed temperature
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.
1. 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.
2. 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.
3. 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.
4. 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.
5. An elevator system according to claim 4 , wherein:
the control system reduces an amount of vertical movement by prolonging a time from a door-open state to a door-closed state.
6. An elevator system according to claim 4 , wherein:
the control system reduces an amount of vertical movement by reducing at least one of a door-opening speed and a door-closing speed.
7. An elevator system according to claim 4 , wherein:
the control system reduces an amount of vertical movement by changing an allocation of calls.
8. An elevator system according to claim 4 , wherein:
the control system reduces an amount of vertical movement by reducing at least one of a speed of the elevator car, an acceleration rate of the elevator car, a deceleration rate of the elevator car, and a change in the acceleration rate of the elevator car.
9. An elevator system according to claim 4 , wherein:
the control system stops movement of the elevator car when the temperature which has been detected reaches an overheating condition.
10. An elevator system according to claim 4 , wherein:
the control system detects temperature of an inverter control circuit.
11. An elevator system according to claim 4 , wherein:
the control system detects temperature of an inverter.
12. An elevator system according to claim 4 , wherein:
the control system detects temperature of a motor.
13. An elevator system according to claim 4 , wherein:
the control system detects temperature of a drive sheave.
14. An elevator system according to claim 4 , wherein:
the control system detects temperature of a rope.
15. An elevator system according to claim 4 , wherein:
the controller which controls the operation of the motor and the control system which detects the temperature and reduces the amount of vertical movement is the same controller.
