Description

Embodiments according to the present invention relate to an elevator control system and an elevator control method.

Elevator systems include double deck elevators that have two cars located one above the other in the same hoistway. Double operation and semi-double operation are known as operation control of a double deck elevator. The double operation is operation control in which one of the two cars shares an even floor with respect to the boarding floor and the destination floor and the other car shares an odd floor. On the other hand, the semi-double operation is an operation control that does not limit the car sharing on the middle floor.

In a double-deck elevator, a passenger registers his or her destination floor in a destination floor registration device installed in the hall. However, the destination registration device does not display the allocation of the upper car and the lower car. Therefore, in the semi-double operation, an erroneous ride may occur in which the passenger mistakenly rides the upper car and the lower car.

In order to avoid erroneous boarding, various techniques for controlling car allocation have been proposed so far.

However, in the conventional technology, a wrong call is avoided when a new destination call is generated with the floor where the destination call has already occurred as the destination floor, and the traveling direction of the car is reversed at the floor where the destination call has already occurred. I couldn't.

International publication WO2013/080242

The present embodiment is made in consideration of such a point, and a new destination call is generated with the floor where the destination call has already occurred as the destination floor, and at the floor where the destination call has already occurred. An object of the present invention is to provide an elevator control system and an elevator control method capable of avoiding an erroneous riding when the traveling direction of a car is reversed.

The elevator control system according to the present embodiment includes a destination floor registration device, an elevator control device, a backward call detection unit, an allocation candidate exclusion unit, and an allocation control unit. The destination floor registration device is installed in an elevator hall having a plurality of cars arranged above and below in the same hoistway, and registers the input destination floor to generate a destination call.

Hereinafter, embodiments according to the present invention will be described with reference to the drawings. This embodiment does not limit the present invention. Further, in the drawings referred to in the embodiments, the same portions or portions having similar functions are designated by the same reference numerals or similar reference numerals, and repeated description thereof will be omitted.

(First embodiment)
The configuration of the elevator control system according to the first embodiment will be described below with reference to FIG. FIG. 1 is a configuration diagram showing an elevator control system 1 according to the first embodiment. The elevator control system 1 according to the first embodiment can be used to control a double deck elevator 2 which is an example of an elevator having a plurality of cars arranged above and below in the same hoistway.

Here, the double deck elevator 2 will be briefly described. The double-deck elevator 2 includes an upper car 21 and a lower car 22 that are examples of a plurality of cars, a destination floor registration device 23, and a unit controller 24 that is an example of an elevator controller. The upper car 21 and the lower car 22 are arranged vertically in the same hoistway. A set of one upper car 21 and one lower car 22 corresponds to the car unit for the first car. The double-deck elevator 2 of the present embodiment is provided with three car units, A-C to C-car. However, the number of car units is not particularly limited. The operation of each unit is individually controlled by the unit controller 24.

In order to control the operations of the cars 21 and 22 in the double deck elevator 2 as described above, the elevator control system 1 includes the destination floor registration device 23 and the single unit control device 24, the backward call detection unit 31, and the allocation candidate. An exclusion unit 32 and an allocation control unit 33 are provided. The backward call detecting unit 31, the allocation candidate excluding unit 32, and the allocation control unit 33 are provided in the elevator group management device 3 that manages a plurality of car units (that is, machine numbers). Hereinafter, the components of the elevator control system 1 will be sequentially described.

The destination floor registration device 23 is a device that is installed in the hall of the double-deck elevator 2 and that registers the input destination floor and generates a destination call.

More specifically, at least one destination floor registration device 23 is installed at each hall of the double deck elevator 2. The destination floor registration device 23 is provided with a registration button 23a for passengers to register the destination floor. The passenger can register both the even floor and the odd floor by using the registration button 23a on each floor. When the destination floor is registered, a destination call signal indicating the destination floor is transmitted from the destination floor registration device 23 to the elevator group management device 3.

The unit control device 24 is a device that controls traveling and door opening/closing of the upper car 21 and the lower car 22 of the corresponding unit.

The backward call detection unit 31 detects a backward call-assigned cage of the upper cage 21 and the lower cage 22 that is the forward cage in the traveling direction and to which the destination call in the opposite direction to the traveling direction is assigned. The allocation control unit 33 may determine which one of the upper car 21 and the lower car 22 is to be assigned (that is, to respond) to the destination call. Further, the backward call detecting unit 31 detects the backward call generation floor at which the backward destination call has occurred.

The allocation candidate excluding unit 32 generates a new destination call on the floor between the backward call allocation car and the backward call generation floor after the generation of the backward destination call, and the destination floor of the new destination call. Is the same as the backward call generation floor, the backward car in the traveling direction for the backward call assigned car of the upper car 21 and the lower car 22 is selected from the candidates for the new call assigned car to be assigned to the new destination call. exclude.

On the other hand, the allocation candidate excluding unit 32, if a new destination call does not occur on the floor between the backward call assignment car and the backward call occurrence floor after the backward destination call occurs, the new call assignment car Is not selected. Further, the allocation candidate excluding unit 32, even if a new destination call occurs on the floor between the backward call assignment car and the backward call generation floor after the occurrence of the backward destination call, the new call When the destination floor of the destination call is different from the backward call generation floor, the car in the traveling direction behind the upper call 21 and the lower call 22 for the backward call assignment car is not excluded from the candidates for the new call assignment car.

When a new destination call occurs on the floor between the backward call allocation car and the backward call generation floor, the allocation control unit 33 determines that the new call is selected from the cars not excluded from the candidates for the new call allocation car. Select an assigned car.

The allocation control unit 33 may select the backward call allocation car as the new call allocation car. As a result, it is possible to easily select a car to which a new call is assigned. The allocation control unit 33 can also select a car of a different machine for each backward call allocation car as a new call allocation car.

Hereinafter, an operation example of the elevator control system 1 according to the first embodiment having the above configuration will be described with reference to FIGS. 2 and 3. FIG. 2 is a flowchart showing an operation example of the elevator control system 1 according to the first embodiment. The flowchart of FIG. 2 is repeated as needed.

As shown in FIG. 2, first, the backward call detection unit 31 of the elevator group management device 3 is a forward car of the upper car 21 and the lower car 22 in the traveling direction, and is a destination call in the direction opposite to the traveling direction. The backward call assigned car to which the call is assigned is detected (step S1).

Further, the backward call detecting unit 31 detects the backward call generation floor at which the backward destination call has occurred (step S2). Step S2 may be interchanged with step S1 before or after, or may be executed simultaneously with step S1.

The destination call is generated according to the input of the destination floor in the destination floor registration device 23 described above. The backward call assignment car may be selected by the assignment control unit 33 of the elevator group management device 3.

The specific method of selecting the backward call assignment car is not particularly limited. For example, the elevator car control system 1 allocates each car 21, such that the lower car 22 shares an odd floor as a boarding floor (that is, a response floor) and a destination floor, and the upper car 21 shares an even floor as a boarding floor and a destination floor, When the allocation of 22 is set and the backward call generation floor is an even floor, the upper car 21 may be selected as the backward call assignment car. However, if there is an even/odd mismatch between the backward call generation floor and the destination floor of the backward destination call, even if the backward call generation floor is an even floor, the backward call assignment car , The lower basket 22 may be selected. In this case, the double deck elevator 2 is temporarily switched from the double operation to the semi-double operation.

Then, the allocation candidate excluding unit 32 determines whether or not a new destination call has occurred on the floor between the backward call allocation car and the backward call generation floor after the occurrence of the backward destination call (step S3).

When a new destination call occurs (step S3: Yes), the allocation candidate excluding unit 32 determines whether the destination floor of the new destination call is the same as the backward call generation floor (step S4). .. On the other hand, if no new destination call is generated (step S3: No), the allocation control unit 33 ends the process without selecting a new call allocation car.

When the destination floor of the new destination call is the same as the backward call generation floor (step S4: Yes), the allocation candidate excluding unit 32 proceeds to the backward call allocation car of the upper car 21 and the lower car 22. The car rearward in the direction is excluded from the candidates for the new call assignment car assigned to the new destination call (step S5). On the other hand, when the destination floor of the new destination call is different from the backward call generation floor (step S4: No), the allocation candidate excluding unit 32 sets the car behind the backward call allocation car in the traveling direction to the new call allocation car. Do not exclude from candidates.

Next, the allocation control unit 33 selects a new call allocation car from the cars not excluded from the candidates for the new call allocation car (step S6).

Hereinafter, the operation provided by the first embodiment will be described. FIG. 3 is an explanatory diagram for explaining the operation of the elevator control system 1 according to the first embodiment.

According to the elevator control system 1 according to the first embodiment configured as described above, after a backward destination call is generated, a new destination is provided on a floor between the backward call allocation car and the backward call generation floor. When a call occurs and the destination floor of the new destination call is the same as the backward call generation floor, the car in the traveling direction rearward of the backward call assigned car of the upper car 21 and the lower car 22 is Can be excluded from the candidates for the new call assignment car.

For example, as shown in FIG. 3, when the traveling directions of the cars 21 and 22 are downward, the passenger 100 inputs the 29th floor to the destination floor registration device 23 on the 26th floor below the positions of the cars 21 and 22. By doing so, it is assumed that a destination call in the opposite direction with the 29th floor as the destination floor occurs. In FIG. 3, the symbol “Δ” indicates that the boarding floor is shared when climbing, the symbol “▽” indicates that the boarding floor is shared when descending, and the symbol “○” indicates that the destination floor is shared. It shows that you do.

In this case, the 26th floor, which is the backward call generation floor, and the 29th floor, which is the destination floor of the destination call in the opposite direction, have different even and odd numbers. Therefore, the assignment control unit 33 originally has an even number as the backward call assignment car. Temporarily select the lower car 22, not the upper car 21, which should share floors.

In this way, after selecting the lower car 22 as the backward call assignment car, on the 28th floor below the positions of the cars 21 and 22, the new passenger 101 inputs the 26th floor to the destination floor registration device 23. It is assumed that a new destination call is generated with the 26th floor as the destination floor.

Here, since the 28th floor, which is the floor where the new destination call is generated, and the 26th floor, which is the destination floor for the new destination call, have an even and odd match, the upper car 21 is originally selected as the new call assignment car. ..

However, if the lower car 22 is selected as the backward call assignment car and the upper car 21 is selected as the new call assignment car as shown in FIG. 3, when the upper car 21 stops on the 26th floor, An existing passenger 100 waiting on the 26th floor accidentally gets into the upper car 21. That is, since the backward call assigned car is the lower car 22, the lower car 22 stops on the 29th floor of the destination floor, and the upper car 21 on which the passenger 100 has boarded incorrectly cannot stop on the 29th floor.

On the other hand, in the present embodiment, a new destination call is generated on the 28th floor between the lower car 22 which is the backward call assigned car and the 26th floor which is the backward call generation floor, and a new destination call is generated. Since the destination floor of the destination call is the same as the backward call generation floor on the 26th floor, the upper car 21 of the upper car 21 and the lower car 22 to the backward call assigned car 22 to the backward call assigned car 22 is the new call assigned car. Can be excluded from the candidates.

Then, the lower car 22 that is not excluded from the candidates for the new call assignment car can be selected as the new call assignment car. Accordingly, on the 28th floor, the new passenger 101 can be placed in the lower car 22 instead of the upper car 21. Then, on the 26th floor, not the upper car 21 but the lower car 22 can be stopped so that the new passenger 101 can be alighted and the existing passenger 100 can be aboard.

As a result, the existing passenger 100 can properly disembark at the destination floor by stopping the lower car 22 on the 29th floor, which is the original destination floor, after reversing the traveling direction.

Therefore, according to the first embodiment, in the case where a new destination call is generated with the floor where the destination call has already occurred as the destination floor and the traveling direction of the car is reversed at the floor where the destination call has already occurred It is possible to avoid a wrong ride.

(Second embodiment)
Next, an elevator control system 1 according to the second embodiment will be described.

In the second embodiment, the allocation candidate excluding unit 32 determines that at least one of the upper car 21 and the lower car 22 has the backward call allocation car when the destination floor is ahead of the backward call generation floor in the traveling direction. Do not exclude the car rearward in the direction of travel from the candidates for the new call allocation car. Here, the case where at least one of the upper car 21 and the lower car 22 has the destination floor ahead of the backward call generation floor in the traveling direction is when the destination floor of the new destination call is not the same as the backward call generation floor. Is an example.

For example, in FIG. 3, when the upper car 21 is a floor below the 25th floor, which is ahead of the 26th floor, which is the backward call generation floor, in the traveling direction, the upper car 21 is excluded from candidates for newly assigned calls. do not do.

According to the second embodiment, the destination floor of the new destination call is set ahead of the backward call generation floor in the traveling direction, so that when the traveling direction of the car does not reverse in the backward call generation floor, the traveling is progressed. Even if a car rearward in the direction is selected as a new call allocation car, it is possible to avoid an erroneous boarding on a floor where the traveling direction of the car is reversed.

(Third Embodiment)
Next, an elevator control system 1 according to the third embodiment will be described.

In the third embodiment, when the positions of the upper car 21 and the lower car 22 are apart from the backward call generation floor by a certain number of floors or more, the allocation candidate excluding unit 32 is located at the rear of the backward call allocation car in the traveling direction. Do not exclude the car from the candidates for the new call allocation car.

Here, if the positions of the upper car 21 and the lower car 22 are apart from the backward call generation floor by a certain number of floors or more, the backward call is assigned in the backward direction until the backward call assignment car reaches the backward call generation floor. There is a possibility that a new destination call will occur with the destination floor located ahead of the call generation floor in the traveling direction.

In such a case, even if the car rearward in the traveling direction with respect to the backward call-assigned car is selected as the new call-assigned car, it may be possible to avoid an erroneous boarding on the floor where the traveling direction of the car is reversed. ..

(Fourth Embodiment)
Next, an elevator control system 1 according to the fourth embodiment will be described.

The elevator control system 1 according to the fourth embodiment is premised on the configuration of the third embodiment. That is, in the fourth embodiment, the single control device 24 selects the car behind the backward call assigned car in the traveling direction as the new call assigned car, and then sets the forward direction ahead of the backward call generation floor as the destination floor. If the destination call is not generated, the traveling direction of the car is not reversed when the car behind the traveling direction is opened at the backward call generation floor.

In the example of FIG. 3, when the upper car 21 on which the new passenger 101 is placed opens the door on the 26th floor, which is the backward call generation floor, the traveling direction indicator lights installed on the 26th floor hall. Displays the downward direction as the traveling direction of the car. Alternatively, the voice guidance device in the upper car 21 gives a voice announcement to the effect that the car is going downward.

Then, the single control device 24 reverses the traveling direction of the car after all the cars in the rear of the traveling direction are closed.

According to the third embodiment, after selecting a car rearward in the traveling direction with respect to the backward call assigned car as a new call assigned car, a destination call occurs in which the destination floor is in the traveling direction front of the backward call generation floor. Even if there is not, it is possible to avoid an erroneous boarding at the backward call generation floor.

(Fifth Embodiment)
Next, an elevator control system 1 according to the fifth embodiment will be described.

The elevator control system 1 according to the fifth embodiment is premised on the configuration of the third embodiment. That is, in the fifth embodiment, the allocation control unit 33 selects a car rearward in the traveling direction with respect to the backward call assigned car as a new call assigned car, and then sets the forward direction in front of the backward call generation floor as the destination floor. If no destination call is generated, the unit controller 24 is notified of a dummy car call or destination call whose destination floor is ahead of the backward call generation floor in the traveling direction.

In this case, the single control device 24 does not reverse the traveling direction of the car at the backward call generation floor.

According to the fifth embodiment, similarly to the fourth embodiment, after selecting a car rearward in the traveling direction with respect to the backward call assigned car as a new call assigned car, the vehicle forward in the traveling direction from the backward call generation floor is selected. Even when a destination call for the destination floor does not occur, it is possible to avoid an erroneous boarding at the backward call generation floor.
