Destination floor buttons 71 and 72 are installed in the cars 61 and 62 for the user to input the destination floor.

Upward and downward call registration devices 41 and 42 are provided at the hall of each floor, and when information on the up and down direction is input by button input by the user, the information on the call registration floor and the direction of up and down is used as the up and down call for each elevator. Output to the control devices 31 and 32 .

The destination floor registration device 50 is provided at a boarding hall of a standard floor or a specific floor, and when a call registration floor and destination floor information by a user are input, group management control is performed using the call registration floor and destination floor information as a destination call. Output to device 10A.

The group supervisory control device 10A of the first embodiment includes an up/down call reception unit 11, a destination call reception unit 12, a call occurrence status reference unit 13, a call occurrence status storage unit 14, a destination floor prediction unit 15, an up/down call reception unit 11, a destination call reception unit 12, a call occurrence status reference unit 13, a A call information conversion unit 16 , a car allocation unit 17 , and an allocation command output unit 18 are provided.

The up-and-down call reception unit 11 receives the information on the call registration floor and the up-and-down destination direction input from the up-and-down call registration devices 41 and 42 as up-and-down calls via the elevator control devices 31 and 32 .

The destination call reception unit 12 receives information on the call registration floor and the destination floor input from the destination floor registration device 50 as a destination call.

When an up-down call from the up-down call registering devices 41 and 42 is detected, the call-up situation reference unit 13 retrieves from the call-up situation storage unit 14 the past call-up situation of boarding from the call registration floor where the up-down call was made. refer.

The call occurrence situation storage unit 14 learns and stores past call occurrence situations of elevators. Specifically, the past destination floors input from the destination floor buttons 71 and 72 by the user who boarded from the call registration floor where the up-and-down calls were made are displayed according to the time zone such as commuting time zone and lunch time zone, and the occurrence of an event. This is a database classified by period. This database can be rewritten to optimal data through learning.

The destination floor prediction unit 15 calculates a predicted destination floor from the referred call occurrence situation. Specifically, based on the call origination date and the call origination time of the up-and-down call, the same time within the most recent fixed day is selected from the up-and-down calls extracted from the call-occurrence status storage unit 14 by the call-occurrence status reference unit 13. Extract the Obi call registration information. Among the extracted call registration information, the floor with the largest number of car call registrations registered by the users who boarded from the registered floor of the up-and-down call is extracted and calculated as an expected floor.

The up-and-down call information conversion unit 16 converts the registered up-and-down call information into information of the same format as the destination call based on the information on the call registration floor and the information on the expected destination floor.

The car allocation unit 17 executes optimum car allocation for the destination call input from the destination floor registration device 50 or the destination call input from the up/down call information conversion unit 16 .

The assignment command output unit 18 outputs an assignment command for the elevator car assigned by the car assignment unit 17 to the elevator controllers 31 and 32 .

<<Processing procedure of the first embodiment>>
The processing procedure of the first embodiment will be described based on the flowchart of FIG.

In the group supervisory control device 10A, the vertical calls from the vertical call registration devices 41 and 42 are monitored by the vertical call reception unit 11, and the destination call from the destination floor registration device 50 is monitored by the destination call reception unit 12 (step S1, S2).

When an up-and-down call is detected by the up-and-down call reception unit 11, the call-occurrence situation reference unit 13 refers to the call-occurrence situation storage unit 14 and searches for an upward or downward car call in the past on the floor where the call originated. (Step S3).

Next, the destination floor prediction unit 15 calculates a predicted destination floor from the referred call occurrence situation. Specifically, based on the call origination date and the call origination time of the up-and-down call, the same time within the most recent fixed day is selected from the up-and-down calls extracted from the call-occurrence status storage unit 14 by the call-occurrence status reference unit 13. Extract the Obi call registration information. Among the extracted call registration information, the floor with the largest number of car call registrations registered by the users who boarded from the registered floor of the up-down call is extracted and calculated as the expected destination floor (step S4).

When the expected destination floor is calculated, the up-down call information conversion unit 16 converts the registered up-down call information into information in the same format as the destination call based on the information on the call registration floor and the information on the expected destination floor ( step S5). This ensures consistency with the data structure of the destination floor call information.

The destination call after conversion is output to the car allocation section 17, and the optimum car is allocated (step S6). On the other hand, if a destination call is detected (step S2 YES), but no up-down call is detected, the destination call is directly output to the car assigning section 17, and the optimum car is assigned (step S6).

The assignment command for the assigned elevator car is output from the assignment command output unit 18 to each of the elevator controllers 31 and 32 (step S7).

As described above, according to the first embodiment, the hybrid DCS can commonly execute allocation processing for destination calls and up/down calls. Therefore, the device configuration can be simplified as compared with the conventional example in which destination calls and up-and-down calls are handled by separate assigning devices.

<<Modified example of the first embodiment>>
The destination floor prediction unit extracts call registration information for the same time period within the most recent fixed day from the call generation status storage unit based on the call generation date and call generation time of the up and down calls, and extracts the extracted call registration information. Among the registration information, among the car call registrations registered by the users who boarded from the registered floors for up and down calls, the top several intermediate floors are calculated as expected floors.

This configuration also provides the same effects as the first embodiment.

<Second embodiment>
<<Configuration of the Second Embodiment>>
FIG. 3 is a block diagram showing the configuration of an elevator system including a group supervisory control device of the second embodiment.

In the first embodiment, when an up-down call is registered, the call occurrence situation reference unit 13 refers to the past call occurrence situation stored in the call occurrence situation storage unit 14, and the destination floor prediction unit 15 stores the past call occurrence situation. It is configured to predict the destination floor based on call generation. In the group supervisory control device 10B of the second embodiment, the call generation situation reference unit 13 and the call generation situation storage unit 14 are eliminated, and when an up-down call is registered, the destination floor prediction unit 19 of the second embodiment directly I try to predict the destination floor.

The destination floor prediction unit 15 is set in advance based on the up-down call information on the call registration floor where the up-down call was made and the up-down call registration time when up-down calls from the up-down call registration devices 41 and 42 are detected. output the expected destination floor.

<<Processing procedure of the second embodiment>>
A processing procedure of the elevator system of the second embodiment will be described based on the flowchart of FIG. The same step numbers are assigned to the same procedures as those in the flowchart of the first embodiment shown in FIG. 2, and the description thereof is omitted.

When an up-down call is detected by the up-down call reception unit 11 (step S1 YES), the destination floor prediction unit 19 presets based on the up-down call information on the call registration floor where the up-down call is made and the registration time of the up-down call. The expected destination floor thus determined is output (step S11). For example, during the commuting time zone, the leaving time zone, or the lunch time zone, the destination floors of calls registered from the calling registration devices 41 and 42 can be almost predicted, so the expected destination floors can be set in advance for each time period. Also, if it is the event holding time, the event holding floor can be predicted as the destination floor.

When the expected destination floor is set in this way, the up-and-down call information conversion unit 16 converts the registered up-and-down call information into information in the same format as the destination call based on the information on the call registration floor and the information on the expected destination floor. (step S5). Since the subsequent processing is the same as in the first embodiment, the description is omitted.

Thus, according to the second embodiment, the same effects as those of the first embodiment can be obtained. Further, since there is no need to provide the call occurrence status reference section 13 and the call occurrence status storage section 14, the configuration of the group supervisory control device 10B can be simplified.

<Third Embodiment>
<<Configuration of the Third Embodiment>>
FIG. 5 is a block diagram showing the configuration of an elevator system to which the group supervisory control device of the third embodiment is applied.

A group supervisory control device 10C of the third embodiment has an allocation control section 20 added to the configuration of the group supervisory control device 10A of the first embodiment.

The allocation control unit 20 confirms the input of the destination call from the destination floor registration device 50 and the input of the top and bottom calls from the top and bottom call registration devices 41 and 42, and if there is an input of the destination call, Based on this, the car allocation unit 17 is instructed to allocate cars. When there is no destination call input but there is an upstream call input, a car allocation unit 17 is instructed to allocate a car based on the destination call converted by the upstream and downstream call information conversion unit 16 .

<<Processing procedure of the third embodiment>>
A processing procedure of the elevator system of the second embodiment will be described based on the flowchart of FIG. The same step numbers are assigned to the same procedures as those in the flowchart of the first embodiment shown in FIG. 2, and the description thereof is omitted.

A group supervisory control device 10C of the third embodiment has an allocation control section 20 added to the configuration of the group supervisory control device 10A of the first embodiment.

The assignment control unit 20 confirms the input of the destination call from the destination floor registration device 50 and the input of the top and bottom calls from the top and bottom call registration devices 41 and 42 . When a destination call is detected by the destination call receiving unit 12 (step S21), the car allocation unit 17 is instructed to assign the destination call to the optimum car prior to the up-and-down call (step S22).

On the other hand, when a destination call is not detected by the destination call receiving unit 12 and a vertical call is detected by the vertical call receiving unit 11 (steps S21 NO, S1), steps S3 to S3 are performed as in the first embodiment. The process of S7 is executed.

Thus, according to the third embodiment, the same effects as those of the first embodiment can be obtained. In addition, since destination calls are assigned to cars with priority over calls for up and down calls, the control load on the group supervisory control device 10C can be reduced as compared with the first embodiment.
