Abstract

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.

Claims (33)

1. An elevator operation control device, comprising:

an operation control device body having registered therein a plurality of operation control profiles for prescribing values regarding operation of an elevator, configured to estimate a future temperature of a drive device that drives a car of the elevator, select one of the operation control profiles in accordance with information on a condition of use of the elevator and the estimated future temperature, and control the operation of the elevator based on the selected operation control profile.

2. The elevator operation control device according to claim 1 , wherein the operation control profiles each include at least one of items composed of a speed of a car, an acceleration of the car, a jerk of the car, a door-opening time, a door-opening speed, and a door-closing speed, and the plurality of operation control profiles are registered as to each of the items.

3. The elevator operation control device according to claim 1 , wherein the operation control device body collects at least one value of an activation frequency of the car, a running distance of the car, a number of passengers, and a number of registrations of calls as the information on the condition of use.

4. The elevator operation control device according to claim 1 , wherein the operation control device body stores information on conditions of use of a past predetermined time.

5. The elevator operation control device according to claim 1 , wherein the operation control device body calculates a transition condition of the condition of use from the information on the condition of use, and selects one of the operation control profiles based on the calculated transition condition.

6. The elevator operation control device according to claim 1 , wherein the operation control device body selects one of the operation control profiles based on an average value of information on conditions of use from a preceding day for each of time zones.

7. The elevator operation control device according to claim 1 , wherein the operation control device body estimates a future waiting time from the information on the condition of use, and selects one of the operation control profiles such that the temperature of the drive device becomes equal to or lower than an allowable value and that the waiting time is minimized.

8. The elevator operation control device according to claim 7 , wherein the operation control device body estimates the future temperature of the drive device from the information on the condition of use and a measured value of a current temperature of the drive device.

9. An elevator operation control device, comprising:

an operation control device body having registered therein a plurality of operation control profiles for prescribing values regarding operation of an elevator, for selecting one of the operation control profiles in accordance with information on a condition of use of the elevator and controlling the operation of the elevator based on the selected operation control profile,

wherein the operation control device body estimates a future temperature of a drive device for driving the car and a future waiting time from the information on the condition of use, and selects one of the operation control profiles such that the temperature of the drive device becomes equal to or lower than an allowable value and that the waiting time is minimized.

10. The elevator operation control device according to claim 9 , wherein the operation control device body estimates the future temperature of the drive device from the information on the condition of use and a measured value of a current temperature of the drive device.

11. A method of controlling an elevator using an elevator operation control device, the method comprising:

registering a plurality of operation control profiles for prescribing values regarding operation of the elevator;

estimating a future temperature of a drive device that drives a car of the elevator;

selecting one of the operation control profiles based on the estimated future temperature and a condition of use of the elevator; and

controlling the operation of the elevator based on the selected operation control profile.

12. The method according to claim 11 , wherein the operation control profiles each include at least one of items composed of a speed of a car, an acceleration of the car, a jerk of the car, a door-opening time, a door-opening speed, and a door-closing speed, and the plurality of operation control profiles are registered as to each of the items.

13. The method according to claim 11 , further comprising:

collecting at least one value of an activation frequency of the car, a running distance of the car, a number of passengers, and a number of registrations of calls as the information on the condition of use.

14. The method according to claim 11 , further comprising:

storing information on conditions of use of a past predetermined time.

15. The method according to claim 11 , further comprising:

calculating a transition condition of the condition of use from the information on the condition of use; and

selecting one of the operation control profiles based on the transition condition from the calculating.

16. The method according to claim 11 , further comprising:

selecting one of the operation control profiles based on an average value of information on conditions of use from a preceding day for each of time zones.

17. The method according to claim 11 , further comprising:

estimating a future waiting time from the information on the condition of use; and

selecting one of the operation control profiles such that the temperature of the drive device becomes equal to or lower than an allowable value and that the waiting time is minimized.

18. The method according to claim 11 , further comprising:

estimating the future temperature of the drive device from the information on the condition of use and a measured value of a current temperature of the drive device.
