Description

Embodiments relate to elevator control devices, elevator control systems, methods and programs.

Conventionally, as an elevator device, a double deck elevator having two cages arranged one above the other in the same hoistway is known.
There are double operation control and semi-double operation control as the operation control of this double deck elevator.

The double operation control is an operation control in which one of the two cars shares the even-numbered floors and the other car shares the odd-numbered floors with respect to the boarding floor and the destination floor.
On the other hand, the semi-double operation control is an operation control that does not limit the division of cars on the middle floors except the top floor and the bottom floor.

International Publication 2013/164882

In a double deck elevator, when a destination floor control system (DCS: Destination Control System) using a landing destination floor registration device (HDC: Hall Destination Controller) that can register a user's destination floor at the landing is applied, it is considered as an odd floor. In semi-double operation where movement to even floors is not restricted, there is a risk that the passenger may not be able to go to the destination floor due to a mistake in riding between the upper and lower cars.

In addition, in full DCS or hybrid DCS, which is a system in which a landing destination floor registration device is installed only on a specific floor and a destination button is set in the car, the user can use the destination button in the car to set the destination floor (stop floor). By giving an additional instruction, a stop schedule that induces erroneous boarding of other passengers on the destination floor may be added.

For example, when the call floor (occurrence floor) is set to the 9th floor (specific floor) and the destination floor is set to the 15th floor by the landing destination floor registration device and the call is assigned to the lower car, the passengers in the upper car make the destination. When the 9th floor is added as a floor, the upper car arrives at the 9th floor first, so there is a possibility that the passenger on the 9th floor who called the destination floor may accidentally get on the upper car.
Therefore, the purpose of this proposal is to prevent erroneous riding between the upper and lower cars even under the semi-double operating condition of full DCS or hybrid DCS.

The elevator control device of the embodiment is an elevator control device that controls the operation of one or more elevators having two cars connected vertically in the same hoistway by a destination floor registration device installed at the landing. An allocation control unit that assigns a destination call to one of the two elevators in one elevator when a destination call is made, and a car inner destination floor installed in the other car after the destination call is assigned. It is provided with an allocation change control unit that changes the allocation destination of the destination call to the other car when the floor on which the destination call is made is instructed as the destination floor by the instruction device.

It is explanatory drawing of the structural example of the elevator control system of embodiment. It is operation processing timing chart of embodiment. It is a processing flowchart of the allocation change determination processing.

Hereinafter, the elevator control system of the embodiment will be described in detail with reference to the drawings.
FIG. 1 is an explanatory diagram of a configuration example of the elevator control system of the embodiment.
The elevator control system 10 is roughly divided into a plurality of double deck elevators 11 (three in the example of FIG. 1), a group management device 12 that performs group management control of the double deck elevator 11, and control of the group management device 12. A plurality of single control devices 13 for controlling each double deck elevator 11 below, a destination floor registration device 14 provided at a landing on a specific floor of a building in which the double deck elevator 11 is provided, and a double deck elevator 11 are provided. It is equipped with a car-calling device 15 having at least one of a car-calling button 15U and 15D provided at a landing on a general floor (a floor other than a specific floor) of a building.

When it is necessary to identify each double deck elevator 11 in the following description, they are referred to as double deck elevator 11A (Unit A), double deck elevator 11B (Unit B) and double deck elevator 11C (Unit C), respectively. It shall be.

Each double deck elevator 11 includes an upper car 22 and a lower car 23 arranged vertically in the same hoistway 21.
Here, the upper car 22 and the lower car 23 have an announcement device 31 for making various announcements and a car inner destination floor instruction device 32 provided with a destination button for designating a destination floor desired by passengers. Each is provided.

The group management device 12 is installed in the other car after the destination call is assigned to one of the upper car 22 and the lower car 23 constituting the double deck elevator 11. When the floor on which the destination call is made is instructed as the destination floor by the instruction device, the assignment change control unit 41 that gives an instruction to change the allocation destination of the destination call to the other car, the waiting time, and the boarding time. It is provided with an allocation control unit 42 that selects a car to be actually stopped based on an allocation evaluation or a change instruction from the allocation change control unit 41, which is an operation prediction evaluation result based on the capacity and the type of destination call.

The single control device 13 controls the traveling and opening / closing of the upper car 22 and the lower car 23 of any one of the corresponding double deck elevators 11. Further, when the double deck elevator 11 is an elevator having an inter-floor adjustment function for adjusting the distance between the upper car 22 and the lower car 23 according to the distance between the stop floors, the inter-floor adjustment is controlled.

The destination floor registration device 14 is installed at a landing on a specific floor of the double deck elevator 11, and registers the input destination floor to generate a destination call.

More specifically, the destination floor registration device 14 is installed at least one at the landing on the specific floor of the double deck elevator 11. The destination floor registration device 14 includes a registration button panel 14A in which a plurality of registration buttons for passengers to register the destination floor are arranged, a wheelchair button 14B for a wheelchair user to call a wheelchair-compatible double deck elevator, and the like. A display panel 14C for displaying various information is provided.

Passengers can operate the registration buttons on each floor of the registration button panel 14A to register as a desired destination floor on either even-numbered floors or odd-numbered floors. Then, when the destination floor is registered, a destination call signal indicating the destination floor is sent from the destination floor registration device 14 to the group management device 12.
These registration information are displayed on the display panel 14C.

At least one car calling device 15 is installed on a general floor other than a specific floor of the double deck elevator 11. The car calling device 15 has an upper calling button 15U for calling a double deck elevator heading to a floor above the floor where the car calling device 15 is provided, and a floor below the floor where the car calling device 15 is provided. At least one of the lower call buttons 15D for calling the double deck elevator heading to the floor is provided.

Next, the operation of the embodiment will be described.
FIG. 2 is an operation processing timing chart of the embodiment.
At the landing on any particular floor, passengers can register for a given destination floor on either even or odd floors using the registration buttons on each floor that make up the registration button panel 14A. It has become.
Therefore, when the passenger registers the destination floor using the registration button of each floor constituting the registration button panel 14A (step S11), the destination call signal indicating the destination floor is transmitted from the destination floor registration device 14 to the group management device 12. Is sent to the allocation control unit 42 of (step S12).

Upon receiving the destination call signal, the allocation control unit 42 selects a car to be actually stopped based on the allocation evaluation, which is an operation prediction evaluation result based on the waiting time, boarding time, capacity, and type of destination call, and assigns the destination call. (Step S13).

More specifically, the allocation control unit 42 assigns the destination call to one of the two cars 22 and 23 of any one of the double deck elevators 11A to 11C.
That is, when the destination is called by the destination floor registration device 14 installed at the landing, the allocation control unit 42 selects one from the plurality of cars 22 and 23 of the plurality of double deck elevators 11A to 11C. Assign a destination call. If there is only one double-deck elevator, one of the cars 22 and 23 of the double-deck elevator will be selected and a destination call will be assigned.

In the following, a case where a destination call is assigned to the upper car 22 of the double deck elevator 11A by the allocation control unit 42 will be described as an example.
When a destination call is assigned to the upper car 22 of the double deck elevator 11A by the allocation control unit 42, and the destination floor is designated by the car inner destination floor indicating device 32 of the lower car 23 of the double deck elevator 11A (step S14). ), The allocation change control unit 41 determines whether or not the deceleration of the upper car 22 or the lower car 23 of the double deck elevator 11A to the scheduled stop floor has started (step S15).
In the determination of step S15, if the deceleration has not been started yet (step S15; No), the allocation change control unit 41 is in the standby state.
In the determination of step S15, if deceleration is started (step S15; Yes), it is necessary to change the assignment of the destination call assigned to the upper car 22 as it is the timing to make the assignment change determination. Is determined (step S16).

Here, the determination of whether or not it is necessary to change the assignment of the destination call will be described in detail.
FIG. 3 is a processing flowchart of the allocation change determination process.
First, the allocation change control unit 41 assigns a destination call to the upper car 22 as one car of the double deck elevator 11, and then indicates the destination floor of the car installed in the lower car 23 which is the other car. It is determined whether or not the same floor as the destination floor corresponding to the destination call assigned to the upper car 22 is designated as the destination floor by operating the destination button of the device 32 (step S21).

In the determination of step S21, if the same floor as the destination floor corresponding to the destination call assigned to the upper car 22 is not yet instructed as the destination floor in the car inner destination floor instruction device 32 in the lower car 23. (Step S21; No), the allocation change control unit 41 ends the allocation change determination process, and shifts the process to step S17.

In the determination of step S21, when the same floor as the destination floor corresponding to the destination call assigned to the upper car 22 is instructed as the destination floor by the car inner destination floor instruction device 32 in the lower car 23 (step S21). Yes), the allocation change control unit 41 determines whether or not the destination floor of the destination call to be assigned is the floor (stop prohibited floor or unstoppable floor) on which the service cannot be provided by the lower basket 23 which is the allocation change destination. Is determined (step S22).

In the determination of step S22, if the destination floor of the destination call to be assigned is the floor on which the service can be provided in the lower basket 23 which is the assignment change destination (step S22; No), the lower basket which is the allocation change destination. It is determined whether or not 23 is in a state where it is not possible to board on the floor where the destination is called due to a temporary reason such as being full (step S24).
In the determination of step S24, if the lower car 23, which is the allocation change destination, is in a state where the passenger can board the floor on the floor where the destination call is made (step S24; No), the allocation change control unit 41 will use the destination call allocation destination. Is set to change to the lower car, which is the other car (step S26), the allocation change determination process is terminated, and the process proceeds to step S17.
In the above explanation, if the lower car 23, which is the assignment change destination, is in a state where it is possible to board on the floor where the destination is called, the allocation change is performed, but the lower car 23, which is the allocation change destination, is the destination. If the car is in a state where it can be boarded on the called floor, and if both the upper car 22 and the lower car 23 are scheduled to be stopped by the car inner destination floor instruction device 32, the destination call assigned car is rearward in the direction of travel. If it is a basket, you may change it.
With this configuration, the destination call is assigned to the car that arrives first on the floor where the destination call is made, so that the passenger who made the destination call can be boarded in the car to which the destination call is assigned. This makes it possible to reliably prevent accidental boarding between the upper and lower cars.

In the determination of step S24, if the lower car 23, which is the allocation change destination, is in a state where it cannot be boarded on the floor where the destination is called due to a temporary reason such as being full (step S24; Yes), the allocation change control unit. In the car inner destination floor instruction device 32, 41 temporarily cancels the setting for control reasons so that the specific floor cannot be instructed as the destination floor, and both the upper car 22 and the lower car Is instructed to the allocation control unit 42 (step S25) so that

In this case, the reason why the instruction device 32 for the destination floor in the car cannot give an instruction with the specific floor as the destination floor is for control reasons such as improvement of operating efficiency, and is physically the destination. This is because it can be set as a floor.

In the determination of step S22, if the destination floor of the destination call to be assigned is a floor (stop prohibited floor or unstoppable floor) that cannot be serviced by the lower car 23 as the other car to which the allocation is changed (step). S22; Yes), it is determined whether or not the destination floor is a stop-prohibited floor and the stop-prohibition is a floor that can be temporarily lifted (step S23).

In the determination of step S23, if the destination floor is a stop-prohibited floor and the stop-prohibition is a floor that can be temporarily lifted (step S23; Yes), the lower car 23 to which the assignment is changed is It is determined whether or not the passenger cannot board the floor on the floor where the destination is called due to a temporary reason such as being full (step S24).

In the determination of step S24, if the lower car 23, which is the allocation change destination, is in a state where the passenger can board the floor on the floor where the destination call is made (step S24; No), the allocation change control unit 41 will use the destination call allocation destination. Is set to change to the lower car, which is the other car (step S26), the allocation change determination process is terminated, and the process proceeds to step S17.
In the above explanation, if the lower car 23, which is the assignment change destination, is in a state where it is possible to board on the floor where the destination is called, the allocation change is performed, but the lower car 23, which is the allocation change destination, is the destination. If the car is in a state where it can be boarded on the called floor, and if both the upper car 22 and the lower car 23 are scheduled to be stopped by the car inner destination floor instruction device 32, the destination call assigned car is rearward in the direction of travel. If it is a basket, you may change it.
With this configuration, the destination call is assigned to the car that arrives first on the floor where the destination call is made, so that the passenger who made the destination call can be boarded in the car to which the destination call is assigned. This makes it possible to reliably prevent accidental boarding between the upper and lower cars.

In the determination of step S24, if the lower car 23, which is the allocation change destination, is in a state where it cannot be boarded on the floor where the destination is called due to a temporary reason such as being full (step S24; Yes), the allocation change control unit. In the car inner destination floor instruction device 32, 41 temporarily cancels the setting for control reasons so that the specific floor cannot be instructed as the destination floor, and both the upper car 22 and the lower car Is set to stop at the floor where the destination call is made continuously (step S25), the allocation change determination process is terminated, and the process proceeds to step S17.

As a result, the allocation change control unit 41 determines whether or not the allocation change is necessary (step S17).
When the allocation change is necessary in the determination in step S17 (step S17; Yes), the allocation change control unit 41 transfers to the allocation control unit 42 based on the setting result in the allocation change determination process (step S16). Give an instruction (step S18).

As a result, the allocation control unit 42 performs the destination call allocation change process (step S18).
If the allocation change is not necessary in the determination of step S16 (step S16; No), the allocation change control unit 41 goes into a standby state.

As described above, according to the present embodiment, the destination call registration device is applied to one of the pair of cars constituting the double deck elevator under the semi-double operation situation in the double deck full DCS or the double deck hybrid DCS. Even if the same floor as the destination floor set by Can be prevented.

Although embodiments of the present invention have been described above, these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in various other embodiments, and various omissions, replacements, and changes can be made without departing from the gist of the invention.

For example, in the above description, the start timing of the allocation change determination process (step S16) of the allocation change control unit 41 is set as the deceleration start timing to the scheduled stop floor.
However, in the timing when the destination floor is newly instructed by the in-car destination call instruction device 32, or in the double deck elevator having the inter-floor adjustment function, the deceleration start timing and the inter-floor adjustment change timing (and the time required for the change). ) Can be taken into consideration.

Further, in the above description, on the floor (stop prohibited floor or unstoppable floor) that cannot be serviced by the destination car (lower car 23 in the above example) corresponding to the destination call to be changed. If there is, and the floor is on a floor where the suspension prohibition cannot be lifted, the allocation will not be changed.

However, even in such a case, the allocation should be changed and the allocation change should be made so that the car to which the allocation is changed is the serviceable floor and the floor closest to the destination floor corresponding to the destination call is the destination floor. It is also possible to. In this case, it is also possible to further configure the announcement device 31 to announce (notify) the passengers that the nearest floor of the destination floor corresponding to the destination call will be stopped as the destination floor.

Alternatively, in the normal hybrid DCS, on the specific floor where the destination call registration device is installed, the car inward destination floor instruction device 32 is in the registration restricted state (use invalid state), but the car inward destination floor instruction device The registration restriction of 32 may be temporarily lifted. In this case, it is also possible to further configure the announcement device 31 to announce (notify) to the passengers that the registration restriction of the car inward destination floor instruction device 32 has been temporarily lifted.
Further, in the above explanation, the destination call is made by the destination floor registration device installed at the landing, and after the destination call is assigned, the destination call is made by the car inner destination floor instruction device installed in the other car. When the destination floor was instructed as the destination floor, the destination call was changed to the other car, but when the car call was made by the car call device, after the car call was assigned as well. , When the floor to which the car is called is designated as the destination floor by the car inner destination floor indicator installed in the other car, the car call allocation destination is changed to the other car. It is also possible to do.
This makes it possible to prevent erroneous boarding between the upper and lower cars.

These embodiments and modifications thereof are included in the scope and gist of the invention as well as the invention described in the claims and the equivalent scope thereof.
