Description

Embodiments of the present invention relate to an elevator system.

An elevator system equipped with a plurality of double-deck elevators including two cars arranged one above the other in the same hoistway is known. The double deck elevator is operated in a double operation mode in which the lower car is landed on only one of the odd and even floors and the upper car is landed on only the other of the odd and even floors, thereby increasing its transport capacity. It is improving.

When the double deck elevator is operated in the double operation mode, passengers boarding from even floors can only register destination calls with even floors as destination floors, and cannot disembark on odd floors. In addition, passengers boarding from odd-numbered floors can only register destination calls with the destination floor as the odd-numbered floor, and cannot get off on even-numbered floors. Therefore, passengers who want to move from even-numbered floors to odd-numbered floors or from odd-numbered floors to even-numbered floors need to use stairs or escalator to move to a landing where the destination floor can be registered as the destination floor. Alternatively, after getting off, it is necessary to use stairs or an escalator to move from the floor where you got off to the destination floor. Such an elevator driving method is very inconvenient for passengers who have difficulty in using stairs and escalators, such as wheelchair users.

In order to solve such a problem, Patent Document 1 discloses a double deck elevator that can be operated in a semi-double operation mode in which upper and lower cars can be landed on both odd-numbered floors and even-numbered floors, respectively. ..

Japanese Unexamined Patent Publication No. 10-21209

However, in the double deck elevator using the landing destination floor registration device where passengers register the destination floor at the landing, the problem is that the passengers mistakenly ride the upper and lower cars when the double deck elevator is operated in the semi-double operation mode. It has become. For example, if a double-deck elevator is operated in semi-double operation mode and the upper and lower cars land on the landing with passengers in succession, the passengers will board the car that landed first on the landing of the upper and lower cars. There is a tendency. However, if the previously landed car is a car that has not responded to the destination call registered by the passenger, the passenger cannot go to the target destination floor.

The present invention has been made in consideration of such points, and is an elevator system including a plurality of double-deck elevators in which destination floors are registered using a landing destination floor registration device, and is up and down by passengers.

(First Embodiment)
Hereinafter, the first embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing a configuration of an elevator system according to the first embodiment. The elevator system 1 shown in FIG. 1 includes a group management control device 10 for group management and control of the operation of the double deck elevators A, B, C of multiple units and the double deck elevators A, B, C of multiple units, and each landing. Includes the landing destination floor registration device 20 provided. In the illustrated example, elevator system 1 includes three double deck elevators A, B, C. However, the number of double deck elevators included in the elevator system 1 is not particularly limited.

Each of the double deck elevators A, B, and C includes a car device 30 that moves up and down in the hoistway, and a single control device 35 that controls the car device 30.

The car device 30 includes an upper car 31 and a lower car 32 for passengers to ride. The upper car 31 and the lower car 32 are vertically connected in the same hoistway, and move up and down together in the hoistway. Each car 31, 32 is provided with a occupancy rate detection unit 33 and a notification unit 34.

In the illustrated example, the occupancy rate detection unit 33 detects the occupancy rate of the cars 31, 32 based on the load capacity in the cars 31, 32 measured by using the in-car load sensor. Of course, the occupancy rate detection unit 33 may detect the occupancy rate by another method. For example, the occupancy rate detection unit 33 detects the occupancy rate of the cars 31, 32 based on the analysis result of the image (video) taken by the cameras installed in the cars 31, 32. good.

The notification unit 34 receives the input from the group management control device 10 and provides various information to the passengers. In the illustrated example, the notification unit 34 notifies information by voice, but the present invention is not limited to this. For example, the notification unit 34 may notify information by means of a video or a signal. The notification unit 34 may be provided at each landing.

The single control device 35 controls the running of the car device 30 and controls the opening and closing of the door. The single control device 35 controls the door opening / closing of the upper car 31 and the door opening / closing control of the lower car 32 independently of each other.

At least one landing destination floor registration device 20 is installed at each landing on each floor. The landing destination floor registration device 20 is provided with a destination floor registration unit 21 for passengers to register the destination floor and a special call registration unit 22 for registering special calls.

In the illustrated example, the landing destination floor registration device 20 includes a numeric keypad for inputting a destination floor. Further, in the illustrated example, the special call registration unit 22 includes a special call registration button, and a special call can be registered by pressing the special call registration button.

The landing destination floor registration device 20 is used when the destination call is registered without a special call, that is, when the destination floor registration unit 21 is operated without operating the special call registration unit 22. Depending on whether the landing on which the registration device 20 is provided is an odd-numbered floor or an even-numbered floor, only one of the odd-numbered floor and the even-numbered floor can be registered as the destination floor. In the illustrated example, if the landing where the landing destination floor registration device 20 is provided is an odd floor, only the odd floor can be registered as the destination floor. Further, if the landing where the landing destination floor registration device 20 is provided is an even floor, only the even floor can be registered as the destination floor.

Further, the landing destination floor registration device 20 is used for odd-numbered floors and even-numbered floors when the destination call is registered with a special call, that is, when the destination floor registration unit 21 is operated together with the operation of the special call registration unit 22. Both can be registered as destination floors.

Here, in the following, a destination call registered without a special call is also referred to as a "normal destination call". A destination call registered with a special call is also called a "special destination call". Therefore, in the following, "when a normal destination call is registered" means a case where a destination call is registered without a special call. Further, "when a special destination call is registered" means a case where a destination call is registered with a special call.

When the destination call is registered, the landing destination floor registration device 20 outputs information about the destination call to the group management control device 10. Specifically, the landing destination floor registration device 20 provides information on the landing (floor) where the destination call is registered, the destination floor included in the destination call, and when the destination call is registered with a special call. (That is, when the destination call is a special destination call) outputs information indicating that fact to the group management control device 10.

Next, the configuration of the group management control device 10 will be described. As shown in FIG. 1, the group management control device 10 has an allocation control unit 11. The allocation control unit 11 selects the unit and the car that respond to the destination call registered by the landing destination floor registration device 20 from the plurality of units A, B, C and the cars 31, 32. In the illustrated example, the allocation control unit 11 includes a storage unit 12, a response unit allocation unit 13, a response car allocation unit 15, and a notification command unit 16.

The storage unit 12 stores information regarding the destination call output from the landing destination floor registration device 20. Specifically, in the storage unit 12, information on the landing (floor) where the destination call is registered and the destination floor included in the destination call, and when the registered destination call is a special destination call, the information is stored. Information indicating that is stored. Further, the storage unit 12 stores information about the unit and the unit assigned as the car and the car that respond to the destination call stored in the storage unit 12.

When a new destination call is registered in the landing destination floor registration device 20 (more specifically, when information about the new destination call is stored in the storage unit 12), the response unit allocation unit 13 performs the destination call. Select the unit that responds to the above from multiple units A, B, and C.

More specifically, when the normal destination call is registered, the response unit allocation unit 13 sets the units that respond to the normal destination call (hereinafter, also referred to as "normal call response unit") to the plurality of units A, B, Select from C. In other words, the response unit allocation unit 13 allocates one of the plurality of units A, B, and C as the normal call response unit when the normal destination call is registered. In the illustrated example, the response unit allocation unit 13 has a predetermined evaluation value (for example, the boarding time of the passengers of the unit when it is assumed that the above-mentioned normal destination call is assigned to the unit, and the capacity of each car of the unit. , The type of destination call assigned to the unit, the waiting time of passengers on each floor, whether or not the unit is assigned as a special call response unit to be described later, etc.), and the normal call response unit is assigned. ..

Further, when the special destination call is registered, the response unit allocation unit 13 selects the unit that responds to the special destination call (hereinafter, also referred to as “special call response unit”) from among the plurality of units A, B, and C. Select. In other words, when the special destination call is registered, the response unit allocation unit 13 allocates one of the plurality of units A, B, and C as the special call response unit. In the illustrated example, the response unit allocation unit 13 has a predetermined evaluation value (for example, the boarding time of the passengers of the unit when it is assumed that the special destination call is assigned to the unit, and the capacity of each car of the unit). , The type of destination call assigned to the unit, the waiting time of passengers on each floor, whether or not the unit is assigned as a special call response unit, etc.), the special call response unit is assigned. However, the present invention is not limited to this, and the response unit allocation unit 13 may allocate a predetermined unit as a special call response unit.

When the normal call response unit or the special call response unit is assigned by the response unit allocation unit 13, the response car allocation unit 15 places the car that responds to the registered destination call on the normal call response unit or the special call response unit. Select from the basket 31 and the lower basket 32. In the response car allocation unit 15, when the normal destination call is registered by the landing destination floor registration device 20 and the normal call response unit is assigned by the response unit allocation unit 13, the landing where the above normal destination call is registered is an odd floor. The car that responds to the normal destination call (hereinafter, also referred to as "normal call answering car") is selected from the upper car 31 and the lower car 32 of the normal call answering machine according to whether it is an even-numbered floor. .. Further, in the response car allocation unit 15, when the special destination call is registered by the landing destination floor registration device 20 and the special call response unit is assigned by the response unit allocation unit 13, the landing where the special destination call is registered is on an odd floor. The car that responds to the above special destination call (hereinafter, also referred to as "special call response car") is selected from the upper car 31 and the lower car 32 of the special call answering machine regardless of whether it is on the even floor or on the even floor. Select.

When a normal destination call is registered, the landing destination floor registration device 20 can register only one of the odd-numbered floor and the even-numbered floor as the destination floor, and the landing where the normal destination call is registered is odd. The allocation unit 17 selects (assigns) either the upper car 31 or the lower car 32 of the normal call response unit as the normal call response car according to whether it is a floor or an even floor, so that the normal call response can be performed. Unit is operated in double operation mode.

Further, when a special destination call is registered, the landing destination floor registration device 20 can register both odd-numbered floors and even-numbered floors as destination floors, and the landing where the special destination call is registered is an odd-numbered floor. The special call response car allocation unit 15 selects (assigns) either the upper car 31 or the lower car 32 of the special call response unit as the special call response car regardless of whether it is an even-numbered floor or the upper car 31. , The special call response unit is operated in the semi-double operation mode.

In the illustrated example, the response car allocation unit 15 has an allocation unit 17 and an allocation change unit 18.

When the normal destination call is registered by the landing destination floor registration device 20 and the normal call response unit is assigned by the response unit allocation unit 13, the allocation unit 17 responds to the normal destination call registered on the even-numbered floor. The upper car 31 is assigned as, and the lower car 32 is assigned as the normal call answering car that responds to the normal destination call registered on the odd-numbered floor. Of course, the allocation unit 17 allocates the upper car 31 as a normal call answering car that responds to the normal destination call registered on the odd-numbered floor, and the lower car 32 as the normal call answering machine that responds to the normal destination call registered on the even-numbered floor. May be assigned. Then, the allocation unit 17 inputs to the storage unit 12 whether the car assigned as the normal call response car is the upper car 31 or the lower car 32. That is, when the upper car 31 is assigned as the normal call response car, it is input to the storage unit 12 that the normal call response car that responds to the normal destination call is the upper car 31. Further, when the lower car 32 is assigned as the normal call response car, it is input to the storage unit 12 that the normal call response car that responds to the normal destination call is the lower car 32.

Further, when the special destination call is registered in the landing destination floor registration device 20 and the special call response unit is assigned by the response unit allocation unit 13, the allocation unit 17 is out of the upper basket 31 and the lower basket 32 of the special call response unit. One car is temporarily assigned as a special call response car. Then, the allocation unit 17 inputs to the storage unit 12 that the special call response car that responds to the special destination call is one of the cars. In the illustrated example, the allocation unit 17 once assigns the allocation to a predetermined evaluation value (for example, the boarding time of a passenger in the car assuming that the special destination call is assigned to the upper car 31 or the lower car 32). Do based on. However, the present invention is not limited to this, and the allocation unit 17 may make the allocation once depending on whether the landing where the special call is registered is an odd-numbered floor or an even-numbered floor.

When the predetermined condition is satisfied, the allocation change unit 18 changes the special call response car stored in the storage unit 12 from one car of the special call response unit to the other car. Alternatively, change to both one car and the other car of the special call answering machine. Alternatively, the destination call assigned to the other car of the special call answering machine is reassigned to one car. In the illustrated example, the allocation change unit 18 has the other car allocation determination unit 181 and the occupancy rate determination unit 182.

The other car allocation determination unit 181 is assigned a destination call to the other car of the special call answering machine so that the other car will land on the landing where the special call is registered before one of the special call answering machines. It is judged whether or not it is. Further, the other car allocation determination unit 181 determines whether or not the destination call registered at the landing where the special call is registered is assigned to the other car.

For example, consider a case where a special destination call having the 6th floor as the destination floor is registered on the 3rd floor, and the lower car 32 of the special call answering machine is one of the cars once assigned as the special call answering car. In this case, at the time of the above determination, the car device 30 of the special call answering machine is located below the 3rd floor, and the destination call registered on the 3rd floor in the upper car 31 which is the other car or the destination whose destination floor is the 3rd floor. If a call is assigned, the other car allocation determination unit 181 is assigned a destination call to land the other car at the landing where the special call is registered before the one car. , Is determined. On the other hand, if the car device 30 of the special call answering machine is above the 3rd floor at the time of the above determination, the destination call registered on the 3rd floor in the upper car 31 which is the other car or the destination whose destination floor is the 3rd floor. Even if a call is assigned, the other car allocation determination unit 181 is not assigned a destination call to land the other car at the landing where the special call is registered before the one car. , Is determined. Then, if the destination call registered on the third floor is assigned to the upper car 31, which is the other car, the other car allocation determination unit 181 is the destination registered at the landing where the special call is registered in the other car. Determine that a call has been assigned.

The occupancy rate determination unit 182 determines whether or not the occupancy rate of the other car of the special call response unit is less than a predetermined value based on the occupancy rate acquired from the occupancy rate detection units 33 provided in the cars 31, 32. Judgment is made.

Then, the allocation change unit 18 determines that the other car allocation determination unit 181 is assigned a destination call to land the other car at the landing where the special call is registered before the one car. If the occupancy rate determination unit 182 determines that the occupancy rate of the other car is less than a predetermined value, the special call response car stored in the storage unit 12 is transferred from one car to the other car. change. This assigns the other car as a special call answer car. Then, the other car responds to the special destination call. Therefore, only the other car will land at the landing where the special call is registered. In addition, passengers who have registered a special call can go to the destination floor (destination floor of the special destination call) by boarding the other car. Therefore, there is no possibility that a passenger who has registered a special call may mistakenly ride the upper and lower baskets 31 and 32.

Further, the allocation change unit 18 determines that the other car allocation determination unit 181 is assigned a destination call to land the other car at the landing where the special call is registered before the one car. If the occupancy rate determination unit 182 determines that the occupancy rate of the other car is equal to or higher than a predetermined value, the special call response car stored in the storage unit 12 is transferred from one car to one car and the other car. Change to both of the other baskets. As a result, both one car and the other car are assigned as special call response cars. Then, both one car and the other car respond to the special destination call. Therefore, both one car and the other car will land on the landing where the special call is registered, but passengers who have registered the special call must go to the destination floor regardless of which car they board. Can be done.

Further, the allocation change unit 18 determines that the other car allocation determination unit 181 has not been assigned a destination call to land the other car at the landing where the special call is registered before the other car. If it is determined that the destination call registered at the landing where the special call is registered is assigned to the other car, the boarding rate of one car determined by the boarding rate determination unit 182 is predetermined. If it is less than the value, the destination call assigned to the other car is reassigned to one car. Specifically, when the normal destination call registered at the landing where the special call is registered is assigned to the other car, the other car is stored in the storage unit 12 as the normal call response car that responds to the normal destination call. As remembered, change this normal call answering car from the other car to one car. As a result, only one car will land on the landing where the special call is registered, and one car will respond not only to the destination call registered with the special call but also to the above-mentioned normal destination call. .. Therefore, only one car will land at the landing where the special call is registered, but passengers who have registered the normal destination call can board one car and go to the destination floor. It should be noted that the case where the other car allocation determination unit 181 determines that the other car is not assigned a destination call for landing the other car at the landing where the special call is registered before the one car. If it is determined that the destination call registered at the landing where the special call is registered is assigned to the other car, the destination call assigned to the other car must be reassigned to one car, or the other car must be reassigned. A passenger who has registered a destination call assigned to the vehicle may not be able to reach the target destination floor by accidentally boarding one of the cars that landed first at the landing. Therefore, by reassigning the destination call assigned to the other car to one car as described above, it is possible to prevent the passenger who registered the destination call from mistakenly riding the upper and lower cars 31, 32.

In addition, the allocation change unit 18 determines that the other car allocation determination unit 181 has not been assigned a destination call to land the other car at the landing where the special call is registered before the other car. If it is determined that the destination call registered at the landing where the special call is registered is assigned to the other car, the occupancy rate of one car determined by the occupancy rate determination unit 182 is predetermined. If it is greater than or equal to the value, the destination call assigned to the other car remains assigned to the other car. In other words, the other car is maintained as a car that responds to the destination call. Therefore, the passenger who has registered the destination call can go to the destination floor (destination floor of the destination call) by getting in the other car. However, in this case, as described above, the passenger who has registered the destination call assigned to the other car may mistakenly board the one car that has landed first at the landing. Therefore, as will be described later, by instructing the passengers who have registered the destination call assigned to the other car to board the other car, it is possible to prevent the passengers from mistakenly riding the upper and lower cars 31, 32.

Further, the allocation change unit 18 determines that the other car allocation determination unit 181 has not been assigned a destination call to land the other car at the landing where the special call is registered before the other car. If it is determined that the destination call registered at the landing where the special call is registered is not assigned to the other car, the storage unit 12 does not depend on the determination result of the occupancy rate determination unit 182. Do not change the special call answering car stored in. This leaves one car assigned as the special call answer car. In other words, one car is maintained as a special call response car. Then, only one of the cars responds to the destination call registered with the special call. In this case, only one of the cars will land at the landing where the special call is registered. In addition, passengers who have registered a special call can go to the destination floor (destination floor of a destination call registered with a special call) by boarding one of the cars. Therefore, there is no possibility that a passenger who has registered a special call may mistakenly ride the upper and lower baskets 31 and 32.

In the illustrated example, the other car allocation determination unit 181 and the occupancy rate determination unit 182 perform the above determination at the following timings. That is, in the other car allocation determination unit 181 and the occupancy rate determination unit 182, the car device 30 of the special call response unit is used to land one of the one car and the other car at the landing where the special call is registered. After starting deceleration, the above determination is made. As a result, the other car allocation determination unit 181 can make a determination in consideration of the destination call assigned to the special call response unit by the time the car device 30 starts decelerating. Further, the occupancy rate determination unit 182 determines based on the occupancy rate of one car and the other car immediately before one car or the other car of the special call response unit lands on the landing where the special call is registered. It can be performed.

If a new destination call (new normal destination call) without a special call is registered before the special call response car lands on the destination floor of the special destination call, the response unit allocation unit 13 will perform a special call. Units other than the response unit are assigned as normal call response units that respond to the new normal destination call. For example, when Unit A is assigned as a special call response unit, the response unit allocation unit 13 selects a normal call response unit that responds to a new normal destination call from Units B and C. As a result, it is possible to prevent a decrease in the transportation efficiency of the special call response unit due to the assignment of a new normal destination call to the special call response unit, and as a result, it is possible to prevent a decrease in the transportation efficiency of the elevator system 1.

In addition, the response unit allocation unit 13 responds when a new destination call with a special call (new special destination call) is registered before the special call response car lands on the destination floor of the special destination call. The unit is assigned as a special call response unit that responds to the new special destination call. For example, when Unit A is assigned as a special call response unit, the response unit allocation unit 13 selects Unit A as a special call response unit that responds to a new special destination call. As a result, it is possible to prevent a decrease in the transportation efficiency of the elevator system 1 due to an increase in the number of special call response units.

The notification command unit 16 inputs a signal to the notification unit 34 to notify the information. When both one car and the other car of the special call response unit are assigned as the special call response car, the notification command unit 16 inputs a signal to the notification unit 34, and the other car registers the special call. When landing at the landing, a guidance urging passengers who have registered a special call to give priority to boarding will be notified. In addition, the notification command unit 16 is a case where both one car and the other car continuously land on the landing where the special call is registered, and the passenger who registered the special call should board. If the other passengers should board differently, a signal is input to the notification unit 34 to indicate which passenger should board which car.

Next, the operation of the elevator system 1 shown in FIG. 1 (particularly the operation of the group management control device 10) will be described with reference to FIGS. 2A and 2B. 2A and 2B are flowcharts showing the operation of the elevator system 1 shown in FIG.

When the passengers operate the landing destination floor registration device 20 to register the destination call, the information regarding the destination call is sent from the landing destination floor registration device 20 to the group management control device 10 and stored in the storage unit 12. .. Then, the response unit allocation unit 13 determines whether or not the destination call is registered with the special call (step S11).

When it is determined in step S11 that the destination call is registered without a special call (NO), the response unit allocation unit 13 selects the normal call response unit from the plurality of units A, B, and C. If any of the multiple units A, B, and C is already assigned as the special call response unit, the normal call response unit is selected from the units other than the special call response unit (step S12). Then, either the upper car 31 or the lower car 32 of the normal call response unit is assigned as the normal call response car by the normal call response car allocation unit 14 (step S13). The allocation result is stored in the storage unit 12. As a result, the normal call response car of the normal call response unit responds to the destination call.

On the other hand, when it is determined in step S11 that the destination call is registered with the special call (YES), the special call response unit is selected from the plurality of units A, B, and C by the response unit allocation unit 13. .. If any of the multiple units A, B, and C is already assigned as a special call response unit, that unit (the unit already assigned as a special call response unit) responds to the above destination call. Selected as the unit (step S14). Then, one of the upper car 31 and the lower car 32 of the special call response unit is temporarily assigned as the special call response car by the allocation unit 17 of the special call response car allocation unit 15 (step S15). Further, one car is stored in the storage unit 12 as a special call response car.

After one car is once assigned as a special call response car, the car device 30 of the special call response unit decelerates in order to land either one car or the other car on the landing where the special call is registered. When started, the other car allocation determination unit 181 determines whether or not the other car is assigned a destination call that causes the other car to land on the landing where the special call is registered before the one car. Is performed (step S16).

When it is determined in step S16 that the other car is assigned a destination call to land the other car at the landing where the special call is registered before the one car (YES), the occupancy rate determination unit 182 Determines whether or not the occupancy rate of the other car is less than a predetermined value (step S17).

Then, when it is determined in step S17 that the occupancy rate of the other car is less than a predetermined value (YES), the other car is assigned as a special call response car (step S18). Specifically, the allocation change unit 18 changes the special call response car stored in the storage unit 12 from one car to the other. As a result, the other car of the special call answering machine responds to the destination call registered with the special call.

On the other hand, when it is determined in step S17 that the occupancy rate of the other car is equal to or higher than a predetermined value (NO), both one car and the other car are assigned as special call response cars. Specifically, the allocation change unit 18 changes the special call response car stored in the storage unit 12 from one car to both one car and the other car. As a result, both one car and the other car of the special call answering machine respond to the destination call registered with the special call. In addition, a signal is input from the notification command unit 16 to the notification unit 34 to notify the passengers who have registered the special call to give priority to the passengers who have registered the special call when the other car lands on the landing where the special call is registered. (Step S19).

When it is determined in step S16 that the destination call for landing the other car in the landing where the special call is registered before the one car is not assigned (NO), the other car allocation determination unit According to 181 it is determined whether or not the normal destination call registered at the landing where the special call is registered is assigned to the other car (step S20).

When it is determined in step S20 that the above normal destination call is assigned to the other car (YES), the occupancy rate determination unit 182 determines whether or not the occupancy rate of one car is less than a predetermined value. It is done (step S21).

If it is determined in step S21 that the occupancy rate of one car is less than a predetermined value (YES), one car is assigned as a car that responds to the above-mentioned normal destination call assigned to the other car. Specifically, the allocation change unit 18 changes the car that responds to the normal destination call stored in the storage unit 12 from the other car to one car. As a result, one car of the special call answering machine responds to the normal destination call assigned to the other car (step S22).

On the other hand, when it is determined in step S21 that the occupancy rate of one car is equal to or higher than a predetermined value (NO), the other car is maintained as a car that responds to the above-mentioned normal destination call assigned to the other car. To. Specifically, the normal call response car that responds to the normal destination call stored in the storage unit 12 is not changed by the allocation change unit 18, and is left as the other car. As a result, both one car and the other car of the special call answering machine will land on the landing where the special call is registered, but one car will respond to the special destination call and the above normal destination call will be made. The other car responds. Further, when one of the cars landed on the landing where the special call was registered from the notification command unit 16 to the notification unit 34, the passenger who registered the special call boarded the other car and the other passengers (above). The passenger who has registered the normal call) is input with a signal to notify the guidance to guide the passenger to board the other car (step S23).

If it is determined in step S20 that the destination call registered at the landing where the special call is registered is not assigned to the other car (NO), one of the assigned cars is maintained as the special call answer car. (Step S24). Specifically, the special call response car stored in the storage unit 12 is not changed by the allocation change unit 18, and is left as one of the cars. As a result, one of the cars of the special call answering machine responds to the destination call registered with the special call.

In the first embodiment described above, in step S19, the allocation change unit 18 does not have to change the special call response car stored in the storage unit 12. In this case as well, both one car and the other car will land at the landing where the special call is registered. However, only one car responds to a destination call with a special call. In addition, the other car will land on the landing where the special call is registered before one car. Therefore, it is assumed that a passenger who has registered a special call accidentally gets in the other car that has landed earlier. In order to prevent such a situation, in this case, the notification command unit 16 inputs a signal to the notification unit 34, and when the other car lands on the landing where the special call is registered, the passenger who registered the special call. It is desirable to notify the guidance to guide the passenger to board one of the following cars.

(Second embodiment)
Next, the elevator system according to the second embodiment will be described with reference to FIGS. 3 to 5.

In the second embodiment shown in FIGS. 3 to 5, the upper basket 31 or the lower basket 32 is landed on a specific floor as compared with the first embodiment shown in FIGS. 1 to 2B. Is prohibited. Another difference is that the allocation change unit 18 of the special call response car allocation unit 15 includes the landing availability determination unit 183. Other configurations are substantially the same as those of the first embodiment. In the second embodiment shown in FIGS. 3 to 5, the same parts as those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

First, as shown in FIG. 4, in the building to which the elevator system 100 is applied, the floor distance between the 4th floor and the 5th floor is larger than the other floor distances, and the lower basket 32 is landed on the 4th floor. If this is done, the upper car 31 cannot be landed on the 5th floor, and if the upper car 31 is landed on the 5th floor, the lower car 32 cannot be landed on the 4th floor. Therefore, in the elevator system 100, it is prohibited to land the lower car 32 of the double deck elevators A, B, and C on the 4th floor, and it is prohibited to land the upper car 31 on the 5th floor. ing. Therefore, even if the special destination call is registered, if the destination floor of the special destination call is the 4th floor, the lower basket 32 cannot be made to respond to the special destination call, and the destination of the special destination call cannot be made to respond. If the floor is the 5th floor, the upper car 31 cannot be made to answer the special destination call.

In such an elevator system 100, when the landing possibility determination unit 183 is temporarily assigned to one of the special call response machines as the special call response car by the allocation unit 17, the other car of the special call response machine is special. It is determined whether or not it is possible to land on the destination floor of the destination call. In the example shown in FIG. 4, if the other car is the lower car 32 and the destination floor of the special destination call is the 4th floor, the landing possibility determination unit 183 arrives at the destination floor of the special destination call. It is determined that the floor cannot be floored. Further, if the other car is the upper car 31 and the destination floor of the special destination call is the 5th floor, the landing possibility determination unit 183 cannot land the other car on the destination floor of the special destination call. , Is determined.

Then, the allocation change unit 18 determines that the other car allocation determination unit 181 is assigned a destination call to land the other car at the landing where the special call is registered before the one car. If the landing availability determination unit 183 determines that the other car can land on the destination floor of the special destination call, the occupancy rate determination unit 182 determines that the occupancy rate of the other car is less than the predetermined value. If it is determined that the above is true, the special call response car stored in the storage unit 12 is changed from one car to the other car. On the other hand, when the landing possibility determination unit 183 determines that the other car cannot land on the destination floor of the special destination call, the allocation change unit 18 is the other car allocation determination unit 181 and the occupancy rate determination unit 182. The special call response car stored in the storage unit 12 is not changed regardless of the determination result.

When the notification command unit 16 determines that the other car allocation determination unit 181 is assigned a destination call to land the other car at the landing where the special call is registered before the other car. Therefore, when the landing possibility determination unit 183 determines that the other car cannot land on the destination floor of the special destination call, when the other car lands on the landing where the special call is registered. A signal for informing the passenger who has registered the special call to guide the passenger to board one of the cars is input to the notification unit 34. This is because, in this case, not only the other car but also one car will land on the landing where the special call is registered, but only one car will respond to the special destination call. In addition, the other car will land on the landing where the special call is registered before the other car. Therefore, there is a risk that a passenger who has registered a special call may accidentally board the other car.

Next, the operation of the elevator system 100 (particularly the operation of the group management control device 10) will be described with reference to FIG. FIG. 5 is a flowchart showing the operation of the elevator system according to the second embodiment. Steps S11 to S24 of FIG. 5 are the same as those of FIGS. 2A and 2B.

As shown in FIG. 5, when it is determined in step S16 that the other car is assigned a destination call for landing the other car at the landing where the special call is registered before the one car (YES). ), The landing availability determination unit 183 determines whether or not the other car can land on the destination floor of the destination call registered with the special call (step S30). If it is determined that landing is possible in step S30 (YES), the process proceeds to step S17. On the other hand, if it is determined in step S30 that landing is not possible (NO), one of the once assigned cars is maintained as a special call response car. Specifically, the special call response car stored in the storage unit 12 is not changed by the allocation change unit 18, and is left as one of the cars. As a result, one of the cars of the special call answering machine responds to the special destination call. In addition, when the other car lands on the landing where the special call is registered, the notification command unit 16 informs the notification unit 34 to guide the passenger who registered the special call to board the following one car. A signal to be notified is input (step S31).

According to the first and second embodiments described above, the elevator systems 1, 100 are double deck elevators A and B of a plurality of units including a car device 30 having an upper car 31 and a lower car 32 connected in the vertical direction, respectively. , C, the landing destination floor registration device 20 including the destination floor registration unit 21 for registering destination calls including the destination floor and the special call registration unit 22 for registering special calls, and the double of multiple units. It is equipped with a group management control device 10 for group management control of the operation of deck elevators A, B, and C. When the destination call is registered without a special call, the landing destination floor registration device 20 determines whether the landing on which the landing destination floor registration device 20 is provided is an odd-numbered floor or an even-numbered floor. When either the odd-numbered floor or the even-numbered floor can be registered and the destination call is registered with a special call, both the odd-numbered floor and the even-numbered floor can be registered as the destination floor. Further, the group management control device 10 has an allocation control unit 11 that assigns a unit that responds to a destination call registered in the landing destination floor registration device 20. The allocation control unit 11 allocates the unit that responds to the registered destination call without a special call as a normal call response unit, and determines whether the landing where the destination call is registered is an odd-numbered floor or an even-numbered floor. Accordingly, either the upper car 31 or the lower car 32 of the normal call answering machine is assigned as the normal call response car that responds to the destination call. Further, the allocation control unit 11 allocates a unit that responds to the destination call registered with the special call as a special call response unit. Further, the allocation control unit 11 temporarily allocates one of the upper car 31 and the lower car 32 of the special call response machine as a special call response car that responds to the special call, and then the upper car 31 of the special call response machine 31. And whether or not the other car of the lower car 32 is assigned a destination call to land the other car at the landing where the special call is registered before the one car above, and the other car. It is determined whether or not the destination call registered at the landing where the special call is registered is assigned to the car. Then, when the allocation control unit 11 determines that the other car is assigned a destination call for landing the other car at the landing where the special call is registered before the other car is assigned, the special call is special. When it is determined that the call answering car is treated as the other car and the other car is not assigned a destination call to land the other car at the landing where the special call is registered before the one car. If it is determined that the destination call registered at the landing where the special call is registered is assigned to the other car, the destination call assigned to the other car is assigned to one car.

According to such an elevator system 1,100, when a special call is not registered, all the units A, B, and C can be operated in the double operation mode to efficiently transport passengers. Then, only when the special call is registered, some of the multiple units A, B, and C (special call response unit) are operated in the semi-double operation mode, and the passengers who have registered the special call are transported without restrictions on the destination floor. can do. Therefore, it is possible to suppress a decrease in the transportation efficiency of the elevator system 1,100 due to the operation of the double deck elevator in the semi-double operation mode. In addition, it is possible to prevent passengers from mistakenly riding the car between the upper and lower cars of the special call answering machine operated in the semi-double operation mode.

Further, according to the first and second embodiments, the allocation control unit 11 decelerates the car device 30 in order to land one of the car and the other car on the landing where the special call is registered. After starting, the above determination is made. As a result, the above determination can be made in consideration of the destination call assigned to the special call answering machine by the time the car device 30 starts decelerating.

Further, according to the first and second embodiments, the allocation control unit 11 does not accompany the special call before the special call answering car lands on the destination floor of the destination call registered with the special call. When a new destination call is registered, a machine other than the special call answering machine is assigned as a normal call answering machine that responds to the new destination call. As a result, it is possible to prevent a decrease in the transportation efficiency of the special call response unit due to the new destination call registered without the special call being assigned to the special call response unit, and as a result, the transportation efficiency of the elevator system 1,100 can be prevented. Can be prevented from decreasing.

Further, according to the first and second embodiments, the allocation control unit 11 newly carries out the special call with the special call before the special call response car lands on the destination floor of the destination call registered with the special call. When a new destination call is registered, the special call answering machine is assigned as the special call answering machine that answers the new destination call. As a result, it is possible to prevent a decrease in the transportation efficiency of the elevator system 1,100 due to an increase in the number of special call response units.

Further, according to the first and second embodiments, the elevator systems 1, 100 further include a occupancy rate detecting unit 33 for acquiring the occupancy rate of each car of the unit assigned as the special call response unit. Then, the allocation control unit 11 determines that the other car is assigned a destination call for landing the other car at the landing where the special call is registered before the one car. If the occupancy rate of the other car is equal to or higher than the predetermined value, the special call response car is used as both one car and the other car. As a result, regardless of whether the passenger who has registered the special call gets in either of the two baskets 31 and 32 of the special call answering machine, the passenger can be transported to the target destination floor. Therefore, even if a passenger gets in the car with a high occupancy rate (the other car) that has landed on the landing where the passenger is located first, out of the two cars 31 and 32 of the special call response unit, the above-mentioned boarding Even if the passenger does not get in the high rate car (the other car) but then gets in the car (one car) that has landed at the landing, the passenger can be transported to the desired destination floor.

Further, according to the first and second embodiments, in the elevator system 1,100, when the special call response car is both one car and the other car, the other car arrives at the landing where the special call is registered. It is further equipped with a notification unit 34 that gives priority to passengers who have registered a special call in the other car when they go to the floor.

Further, according to the first and second embodiments, the elevator system 1,100 has a occupancy rate detection unit 33 for acquiring the occupancy rate of each car 31, 32 of the unit selected as the special call response unit, and a notification unit 34. And, further equipped. Then, when it is determined that the other car is assigned a destination call for landing the other car at the landing where the special call is registered before the one car, the occupancy rate of the other car is high. If it is equal to or more than a predetermined value, the allocation control unit 11 keeps the special call response car as one car, and the notification unit 34 specializes when the other car lands on the landing where the special call is registered. Notify the guidance to guide the passenger who registered the call to board one of the cars. As a result, both the two cars 31 and 32 of the special call answering machine land on the landing where the special call is registered, but the car that landed first on the landing is responding to the special call. It is possible to reduce the risk that a passenger who has registered a special call in the other car will accidentally get on the car.

Further, according to the second embodiment, the elevator system 100 further includes a notification unit 34. Further, the allocation control unit 11 temporarily allocates one of the upper car 31 and the lower car 32 of the special call response machine as a special call response car that responds to the special call, and then the upper car 31 of the special call response machine 31. And whether or not the other car of the lower car 32 is assigned a destination call to land the other car at the landing where the special call is registered before the one car, and the other car. It is determined whether or not the car can land on the destination floor of the destination call registered with the special call. Then, the allocation control unit 11 determines that the other car is assigned a destination call for landing the other car at the landing where the special call is registered before the other car, and the other If it is determined that the car cannot land on the destination floor of the destination call registered with the special call, the special call answer car is left as one car. Further, in this case, when the other car lands on the landing where the special call is registered, the notification unit 34 notifies the passenger who registered the special call to guide the passenger to board the one car. do. As a result, when the other car lands earlier than one car at the landing where the special call is registered, and the destination call registered with the special call cannot be assigned to the other car. , Both of the two cars 31 and 32 of the special call answering machine land on the landing where the special call is registered, but the other car that landed first on the landing and did not respond to the special call. It is possible to reduce the risk that a passenger who has registered a special call in the car will accidentally get on the car.
