Abstract

When a specific destination floor call is made, the control unit assigns an elevator of which waiting time is within the reference time from the plurality of elevators to the specific destination floor call, the waiting time being a time from a time when the specific destination floor call is made to a time when the specific user can get on an elevator at the specific floor. Further, when a general destination floor call is made, the control unit assigns one of the plurality of elevators in response to the general destination floor call such that an elevator of which waiting time to the specific destination floor call that is made after the general destination floor call is within the reference time is left.

Claims

1. An elevator group management system comprising:

a destination floor registering device with which a user inputs a destination floor; and

a control device configured to assign one of a plurality of elevators based on the destination floor registered with the destination floor registering device to a destination floor call that is based on the destination floor, wherein

the destination floor registering device comprises

a destination floor input unit configured to input a destination floor from the user, and output a signal related to the input destination floor to the control device, and

a user input unit configured to receive from a specific user, information indicating that a user inputting the information is the specific user, and output to the control device a specific signal indicating that a user is the specific user,

the control device comprises

a storage unit configured to store a reference time and a specific floor associated with the specific user, and

a control unit, wherein

when the destination floor call is a specific destination floor call, the control unit assigns an elevator of which waiting time is within the reference time from the plurality of elevators to the destination floor call, the specific destination floor call being a call made with the specific signal is inputted when the signal related to the destination floor is inputted from the destination floor registering device, the waiting time being a time from a time when the specific destination floor call is made to a time when the specific user can get on an elevator at the specific floor, and

when the destination floor call is a general destination floor call, the control unit assigns one of the plurality of elevators in response to the general destination floor call to the destination floor call such that an elevator of which waiting time to the specific destination floor call which is made after the general destination floor call is within the reference time is left, the general destination floor call being a call made with the specific signal not inputted when the signal related to the destination floor is inputted from the destination floor registering device.

2. The elevator group management system according to claim 1, wherein the control unit assumes that the general destination floor call is assigned to each of the plurality of elevators when the general destination floor call is made, and determines whether or not there is an elevator of which waiting time for the specific destination floor call which is made after the general destination floor call is within the reference time,

when it is determined that there is an elevator of which waiting time is within the reference time, the control unit sets the elevator to which the determination as to the waiting time is performed, as a candidate elevator to the general destination floor call,

when it is determined that there is no elevator of which waiting time is within the reference time, the control unit does not set the elevator to which the determination as to the waiting time is performed, as the candidate elevator to the general destination floor call, and

the control unit determines an elevator to be assigned in response to the general destination floor call from the candidate elevators according to a predetermined rule.

3. The elevator group management system according to claim 1, wherein the control unit assumes that the specific destination floor call is assigned to each of the plurality of elevators when the specific destination floor call is made, and determines whether or not a waiting time for the specific destination floor call with respect to the assumed elevator is within the reference time,

when it is determined that the waiting time is within the reference time, the control unit sets the elevator to which the determination as to the waiting time is performed, as a candidate elevator in response to the specific destination floor call,

when it is determined that the waiting time is not within the reference time, the control unit does not set the elevator to which the determination as to the waiting time is performed, as the candidate elevator in response to the specific destination floor call, and

the control unit determines an elevator to be assigned in response to the specific destination floor call from the candidate elevators according to a predetermined rule.

4. An elevator group management system comprising:

a destination floor registering device with which a user registers a destination floor; and

a control device configured to assign one of a plurality of elevators based on the destination floor registered with the destination floor registering device to a destination floor call that is based on the destination floor, wherein

the destination floor registering device comprises

a destination floor input unit configured to input a destination floor from the user, and output a signal related to the inputted destination floor to the control device, and

a user input unit configured to receive from a specific user, information indicating that a user inputting the information is the specific user, and output to the control device a specific signal indicating that a user is the specific user,

the control device comprises

a storage unit configured to store a reference time and a specific floor associated with the specific user, and

a control unit, wherein

when the destination floor call is a specific destination floor call, the control unit assigns an elevator of which service completion time is within the reference time from the plurality of elevators to the destination floor call, the specific destination floor call being a call made with the specific signal is inputted when the signal related to the destination floor is inputted from the destination floor registering device, the service completion time being a time from a time when the specific user gets on an elevator at the specific floor after a specific destination floor call is made to a time when the specific user can get off the elevator at the destination floor, and

when the destination floor call is a general destination floor call, the control unit assigns one of the plurality of elevators in response to the general destination floor call to the destination floor call such that an elevator of which service completion expected time at which a service is expected to complete to the specific destination floor call which is made after the general destination floor call is within the reference time is left, the general destination floor call being a call made with the specific signal not inputted when the signal related to the destination floor is inputted from the destination floor registering device.

5. The elevator group management system according to claim 4, wherein the control unit assumes that the general destination floor call is assigned to each of the plurality of elevators when the general destination floor call is made, and determines whether or not there is an elevator of which service completion time for the specific destination floor call which is made after the general destination floor call is within the reference time,

when it is determined that there is an elevator of which service completion time is within the reference time, the control unit sets the elevator to which the determination as to the service completion time is performed, as a candidate elevator in response to the general destination floor call,
