Description

Elevator and control method

Technical Field

The present invention relates to an elevator having a function of supplying power to a power storage device mounted on a car in a non-contact manner, and a control method.

Background

A typical elevator supplies electricity to equipment within the car through an electricity supply line called a tail cable suspended from the car. However, recently, a super high-rise building has been constructed, and when an elevator is installed in the super high-rise building, the installed elevator has a long stroke. When the elevator has a long stroke, the tail cable becomes long and the mass thereof also increases, and if the length exceeds a certain length, the weight cannot be received. However, when the tail cable is removed, there is a problem in supplying power to the devices in the car of the elevator.

As a method of supplying power to devices in a car, for example, as shown in patent document 1, there is disclosed a method of supplying power using non-contact power supply during a stop, charging a power storage device mounted on the car, and supplying power from the power storage device during a running.

In an elevator having such a car mounted with a power storage device, there is a possibility that the operation efficiency is lowered when the remaining power level is lowered. Patent document 1 discloses a measure in which, as the electric energy required for a response to a call from an elevator lobby, each elevator control device provided for each elevator predicts the electric energy required for movement from the floor where the current car is located to the floor where the call is made (hereinafter referred to as "call floor") and the movement time from the call floor to the destination floor, calculates a predicted value obtained by adding the predicted value to reserve electric energy assumed to be consumed in the stop time, and excludes allocation when the remaining electric energy is lower than this value.

Disclosure of Invention

However, in the technique described in patent document 1, the amount of electricity consumed by the car during the stop of the car at a floor where electricity cannot be supplied (hereinafter referred to as "non-power supply floor") is calculated in the reserve electricity amount, but the floor where electricity can be supplied (hereinafter referred to as "power supply floor") and the non-power supply floor are not distinguished. Therefore, the reserve power amount becomes large, and the power storage device mounted on the car may increase.

On the other hand, even if the power storage device stores a certain amount of power as a backup, if the car is continuously stopped at the non-power supply floor, the remaining power level is greatly reduced, and therefore there is a possibility that the service (operation of the elevator) may be stopped in the middle.

In view of the above circumstances, a method is desired for suppressing an increase in the storage capacity and reliably suppressing a decrease in the remaining storage capacity in an elevator having a car mounted with a power storage device.

An elevator according to one aspect of the present invention includes: a car on which a power storage device provided for each of the plurality of elevators is mounted; and a group management control device which controls the operation of the cars of the elevators, which supply power when the cars stop at the power supply floor, in response to the call floor information based on the call signal for calling the cars and the destination floor information based on the registration signal for registering the destination floor.

The group management control device further includes a power supply floor setting storage unit that stores power supply floor setting information that is information of a power supply floor of each elevator, and controls the operation of the car of each elevator so as not to exceed a predetermined value of the number of times of continuous stop allowance to a non-power supply floor to which power supply is not possible, based on at least the call floor information, the power supply floor setting information, and registered destination floor information including information of a call floor and a destination floor that have been registered before the call signal is received.

Effects of the invention

According to at least one aspect of the present invention, it is possible to reliably suppress a decrease in the battery power level while suppressing an increase in the storage capacity of the power storage device mounted on the car.

Problems, structures, and effects other than those described above will become apparent from the following description of the embodiments.

<1 > first embodiment >

[ integral Structure of Elevator System ]

First, an overall configuration example of an elevator system that performs contactless power feeding according to the first embodiment will be described.

Fig. 1 is a schematic configuration diagram showing an example of the overall configuration of an elevator system that performs contactless power feeding. An elevator system 1 (an example of an elevator) shown in fig. 1 is an example in which a destination floor registration device is provided in an elevator hall at each floor. Here, since the operation control method and the power supply system of the car are explained, the detailed configuration and the device wiring of the elevator such as the suspension rope, the guide rail, and the guide roller will not be explained. Further, as the power feeding system of the present embodiment, non-contact power feeding using electromagnetic induction between coils is assumed, but a non-power feeding system based on electric field coupling or electromagnetic waves (microwaves) can also be applied.

The elevator system 1 is configured by 3 elevators, i.e., an elevator a, an elevator B, and an elevator C, to form one elevator group, and performs allocation and operation control of an elevator (elevator) for a call from an elevator hall (hereinafter, sometimes referred to as an "elevator hall call") by the group management control device 20. In fig. 1, floors of 1, 2, 3, 4 and 5 floors are shown.

Elevator controllers 11a, 11B, and 11C are provided for elevator a, elevator B, and elevator C, respectively. The

elevator control devices

11a, 11b, and 11c are provided corresponding to the respective elevators, and perform drive control and door opening/closing control of a hoist (not shown) that winds a rope connecting a car and a counterweight (not shown) of each elevator. Thereby, the

cars

12a, 12b, and 12c of the elevators perform lifting operations in the respective lifting/lowering paths. In the following description, the elevator control device 11a, the elevator control device 11b, and the elevator control device 11c will be referred to as an elevator control device 11 unless otherwise specified. When the car 12a, the car 12b, and the car 12c are not distinguished, they are referred to as the car 12.

The battery power level Est of the battery device 33 mounted on each of the cars 12a to 12C of the elevator a, the elevator B, and the elevator C is transmitted from the car device 34 to each of the elevator control devices 11a to 11C via a communication line. The remaining battery power Est of the power storage device 33 mounted on the car 12 of each elevator is transmitted from each of the elevator control devices 11a to 11c to the group management control device 20 via the communication line. The battery power level Est is represented by a ratio [% ] to a fully charged state of the power storage device 33.

Further, as information from the elevator hall destination floor registration device 13, the floor (call floor Fc) on which the destination floor registration operation is performed and the registered destination floor Fd are transmitted to the group management control device 20 via the communication line. Information generally used for group management, such as the position and load information in the building (in the hoistway) of each of the cars 12a to 12c, is also transmitted from each of the elevator control devices 11a to 11c, but not shown here. The group management control device 20 determines an elevator to be actually allocated from among candidates for allocation of call amount based on information such as the battery power level Est, the call floor Fc, and the destination floor Fd, and outputs the determined elevator as an allocation result AR to the corresponding elevator (elevator).

On the other hand, an elevator lobby floor registration device 13 for reserving (registering) a floor of interest by a user is provided in front of or in an elevator lobby of each floor of a building. The elevator hall destination layer registration device 13 includes: an operation unit 14 for performing an input operation by a user, and a display unit 15 for displaying an assigned elevator. In fig. 1, reference numerals indicating the operation unit 14 and the display unit 15 are given to only the elevator hall destination layer registration device 13 at 5 floors. The operation unit 14 outputs a call signal for calling the car 12 and a registration signal corresponding to the destination floor inputted to the corresponding elevator control device 11 via a communication line. As a method of registering a destination layer, an operation based on a numeric key in which a number is written is generally used, but voice processing or wireless communication may be used as long as the destination layer can be registered.

A car 12a of the elevator a is mounted with a power receiving unit 32 formed of a power receiving coil or the like, a power storage device 33, and car equipment 34. On the other hand, a power transmission unit 31a formed of a power transmission coil or the like is provided on a side wall in the hoistway of the elevator a for each floor. Power transmission unit 31a supplies power to power reception unit 32 mounted on car 12a of elevator No. a in a non-contact manner, and power storage device 33 is charged via power reception unit 32. Then, the electric power stored in the power storage device 33 is supplied to the car equipment 34 mounted on the car 12 a. The car device 34 includes, for example, a door opening/closing device, a controller, a display, and the like. The car device 34 communicates with the elevator control device 11a of the elevator a via a communication line (wireless transmission in the case where the tail cable is removed).

The same applies to the car 12B of the elevator No. B and the car 12C of the elevator No. C. Power is supplied in a non-contact manner from a power transmission unit 31B provided in a side wall of the hoistway of the No. B elevator corresponding to a floor and a power receiving unit 32 mounted on the car 12B of the No. B elevator, and the power storage device 33 is charged. Further, power is supplied in a non-contact manner from a power transmission unit 31C provided in a side wall in the hoistway of the No. C elevator corresponding to a floor and a power receiving unit 32 mounted on the car 12C of the No. C elevator, and the power storage device 33 is charged. In the following description, the power transmission unit 31a, the power transmission unit 31b, and the power transmission unit 31c will be referred to as the power transmission unit 31 unless otherwise specified. In fig. 1, the power receiving unit 32 is shown by filling in when non-contact power is supplied from the power transmitting unit 31 and the power receiving unit 32, or when the positional relationship between the power transmitting unit 31 and the power receiving unit 32 is such that non-contact power supply is possible.

Here, the power transmission unit 31a of the elevator a is provided on three floors, i.e., the 1 st floor, the 2 nd floor, and the 4 th floor, and the car 12a can supply power when stopping at these floors. The power transmission unit 31B of the elevator car No. B is provided on two floors, i.e., the 1 st floor and the 5 th floor, and the power transmission unit 31C of the elevator car No. C is provided corresponding to three floors, i.e., the 1 st floor, the 2 nd floor, and the 5 th floor. The manner of providing the power supply layer is not limited to this example, but is set here for the following reasons.

First, floor 1 is the first floor, which is the floor with the most passengers. Floor 1 is also called the reference floor of the elevator, and an empty car with no user often waits on the reference floor. Therefore, the stop time of layer 1 is large and the stop frequency is high, and both the charging time and the improvement in serviceability (reduction in waiting time) can be ensured. Therefore, in the present embodiment, the power transmission unit is provided for all elevators on floor 1, and floor 1 is provided as a floor to which power can be supplied to all three elevators, i.e., elevator a, elevator B, and elevator C. Two power transmission units (power transmission unit 31a of elevator No. a and power transmission unit 31C of elevator No. C) are provided at floor 2.

Here, the more the number of power supply layers, the more the opportunity to charge the power storage device 33 of the car increases, and therefore, the increase in the power storage capacity of the power storage device 33 can be suppressed. However, by reducing the number of power supply layers, the cost including the installation of the power transmission unit can be reduced. Therefore, in the elevator system 1, the 3-floor is set as a floor (non-power supply floor) to which elevator cannot supply power. In addition, the power transmission unit 31a of the elevator No. a is provided on the 4 th floor, and the power transmission unit 31B of the elevator No. B and the power transmission unit 31C of the elevator No. C are provided on the 5 th floor. By changing the setting of the power supply floor (presence or absence of the power transmission unit for each floor) according to the elevator in this way, it is possible to avoid a situation in which it takes an extremely long time when the cars of the elevators move to a specific floor, and the serviceability is improved.

In the present embodiment, the number of floors to which power cannot be supplied by all elevators is set to be equal to or less than the number of elevators. With such a configuration, there is no time zone in which all elevators stop at the non-power supply floor, and one or more elevators are always in operation, and thus service can be continuously provided to users.

The group management control device 20 according to the present embodiment obtains at least: the call floor Fc based on the call signal for calling the car 12, the power supply layer setting information, which is information on the power supply layer of each elevator, and the registered destination floor information including the information on the call floor and the destination floor registered before the call signal is received. Then, the group management control device 20 controls the operation of the car 12 of each elevator so as not to exceed a predetermined value (the number of consecutive no-power supply permitted times) of the number of consecutive stop permitted times to the non-power supply layer to which power supply is not permitted, based on at least the call floor Fc, the power supply layer setting information, and the registered destination floor information.

For example, in the case of an a-size elevator, when the car 12a is stopped continuously at 3 floors and 5 floors where the power transmission unit 31a is not provided, the car 12a is stopped continuously at the non-power supply floor. The number of consecutive stops to the non-power supply layer is counted by successively setting "1" twice when the car 12 stops to the non-power supply layer two or more times in succession, and incrementing the value by 1 every time after the third time. For example, when the car 12 stops to the non-power supply layer discontinuously, the number of consecutive stops to the non-power supply layer is calculated as "0", when the car stops to the non-power supply layer twice consecutively, the number of consecutive stops to the non-power supply layer is calculated as "1", and when the car stops to the non-power supply layer three times consecutively, the number of consecutive stops to the non-power supply layer is calculated as "2". The predetermined value of the number of continuous stop permission times to the non-power supply layer (the number of continuous non-power supply permission times) is a value of the number of continuous stop permission times to the non-power supply layer.

[ internal Structure of group management control device ]

Fig. 2 is a block diagram showing an example of the internal configuration of the group management control device 20.

The group management control device 20 includes: a battery remaining amount determination unit 21, a power supply control unit 22, an allocation candidate extraction unit 23, and an allocation control unit 24.

The remaining battery level determining unit 21 determines whether or not the remaining battery level Est of the power storage device 33 mounted on the car 12 of each elevator is equal to or greater than a threshold Eth (Est ≧ Eth), and outputs the determination result to the power supply control unit 22 or the assignment candidate extracting unit 23. The information of the threshold Eth is held in, for example, a register provided in the CPU51 shown in fig. 11 and a ROM52 shown below. Generally, an elevator provided with a power supply system is provided with a battery level determination unit 21.

When the battery power level Est is less than the threshold Eth, the power supply control unit 22 sets the corresponding elevator to the power supply mode as the battery power level is insufficient. Here, the power feeding mode is a mode in which the corresponding elevator is excluded from the allocation candidates and power is fed by moving the car 12 to the power feeding floor. When the car 12 reaches the power supply floor, non-contact power supply is performed from the power transmitting unit 31 to the power receiving unit 32, and the power storage device 33 is charged. If the corresponding car 12 is in the middle of the transportation of passengers, the transition to the power supply mode is to the power supply floor after the completion of its service. Therefore, the threshold Eth is determined in advance in consideration of the standard time required for the power supply layer to be reached.

The allocation candidate extracting unit 23 operates when the battery power level Est of the battery device 33 of the car 12 of each elevator in the battery power level determining unit 21 is equal to or greater than the threshold Eth. The allocation candidate extracting unit 23 extracts, as allocation candidates, elevators whose car 12 does not exceed a predetermined value of the number of consecutive stop allowability times to the non-power supply floor, based on the call floor Fc (call floor information), the destination floor Fd (destination floor information), the power supply floor setting information, which is information on the power supply floor of each elevator (presence or absence of the power transmitting unit of each floor), and the registered destination floor information of each elevator.

(configuration of allocation candidate extracting section)

Here, the allocation candidate extracting unit 23 will be further described. As shown in fig. 2, the allocation candidate extraction unit 23 includes: a power supply floor setting storage unit 231, an elevator lobby floor power supply determination unit 232, a destination floor power supply determination unit 233, a continuous non-power supply determination unit 234, a registered destination floor list 235, and an allocation candidate list 236.

The power supply layer setting storage unit 231 is a nonvolatile storage unit that stores the power supply layer setting information. In fig. 2, the power supply layer setting storage unit 231 is provided in the allocation candidate extraction unit 23, but may be provided in the group management control device 20.

The elevator hall floor power supply determination unit 232 determines whether or not the call floor Fc output from the elevator hall destination floor registration device 13 is a power supply floor with reference to the power supply floor setting information of the power supply floor setting storage unit 231, and outputs the determination result to the continuous non-power supply determination unit 234.

The destination power supply determining unit 233 determines whether or not the destination floor Fd output from the elevator hall destination floor registration device 13 is a power supply floor with reference to the power supply floor setting information of the power supply floor setting storage unit 231, and outputs the determination result to the continuous non-power supply determining unit 234.

The continuous non-power-supply determining part 234 determines whether the number of times of continuous stop of the car 12 of each elevator to the non-power-supply floor exceeds the allowable number (predetermined value) based on each determination result of the elevator hall floor power-supply determining part 232 and the destination floor power-supply determining part 233, the registered destination floor list 235, and the power-supply floor setting information. The registered destination floor list 235 stores information on the call floor and the destination floor that have been registered before the call floor Fc is received from the elevator hall destination floor registration device 13. When the number of consecutive stops of the car 12 to the non-power supply floor does not exceed the allowable number, the corresponding elevator is registered as an allocation candidate for an elevator hall call in the allocation candidate list 236. The allocation candidate list 236 is stored in, for example, a RAM53 in fig. 11 described later.

The assignment control unit 24 determines an assigned elevator for a call signal (elevator hall call) output from the elevator hall destination floor registration device 13 from the elevators extracted by the continuous non-power supply determination unit 234 and registered as assignment candidates in the assignment candidate list 236. The assignment control unit 24 outputs the assigned elevator to the corresponding elevator control device 11 as the assignment result AR.

[ procedure for assigning Elevator decision method ]

Fig. 3 is a flowchart showing a procedure of an assigned elevator decision method in the group management control device 20.

As a premise, the group management control device 20 determines whether or not the battery power level Est of the battery device 33 mounted on the car 12 of each elevator is equal to or greater than the threshold Eth (Est ≧ Eth) by the battery power level determining unit 21 (S1). When the battery power level Est is less than the threshold Eth (no in S1), the group management control device 20 shifts the corresponding elevator to the power feeding mode as the battery power level is insufficient (S2). Then, the power supply control unit 22 controls the power supply mode.

On the other hand, when the battery power level Est of the power storage device 33 is equal to or greater than the threshold Eth (yes in S1), the elevator lobby floor power supply determination unit 232 determines whether the call floor Fc is the power supply floor or the non-power supply floor, based on the information on the call floor Fc and the destination floor Fd and the information on the power supply floor of each elevator stored in the power supply floor setting storage unit 231 (S3). By determining which of the power supply layer and the non-power supply layer the call layer Fc is, the group management control device 20 can grasp whether or not the car 12 is continuously stopped to the non-power supply layer from before to after the stop at the call layer Fc.

Further, when the determination result in step S1 is yes, the destination layer feed determination unit 233 determines whether the destination layer Fd is a feed layer or a non-feed layer in parallel with the processing in step S3 (S4). By determining which of the power supply layer and the non-power supply layer the destination layer Fd is, the group management control device 20 can grasp whether or not the car 12 is continuously stopped at the non-power supply layer from before to after stopping at the destination layer Fd.

Next, after the processing of steps S3 and S4, the continuous non-power-supply determining unit 234 determines whether or not the number of times of continuous stop of the car 12 of the target elevator to the non-power-supply floor exceeds a predetermined number of times of continuous non-power-supply permission, based on the determination result of the call floor Fc of step S3, the determination result of the destination floor Fd of step S4, and the information of the destination floor already registered in the registered destination floor list 235 before receiving the information of the call floor Fc (S5). For example, in the present embodiment, the predetermined value of the number of consecutive no-power-supply permission times is set to "0" times. When the number of times of continuous non-power supply permission is 0, the car 12 is not allowed to continuously stop at the non-power supply floor.

In the determination processing in step S5, if it is determined that the number of times the car 12 of the target elevator is continuously stopped on the non-power supply floor does not exceed the predetermined number of times the continuous no-power supply is permitted (no in S5), the continuous no-power supply determination unit 234 extracts the target elevator as an allocation candidate and registers the target elevator in the allocation candidate list 236 (S6). On the other hand, when determining that the number of times of continuous stop of the car 12 of the target elevator to the non-power supply floor exceeds the predetermined number of times of continuous no-power supply allowance (yes at S5), the continuous no-power supply determination unit 234 excludes the target elevator from the allocation candidates (S7).

After the processing of step S6 or step S7, the assignment control unit 24 determines an assigned elevator for the call signal (elevator hall call of the call floor Fc) from the elevators registered as assignment candidates in the assignment candidate list 236 according to a predetermined rule, and outputs the determined assigned elevator as the assignment result AR to the corresponding elevator control device 11 (S8). The elevator control device 11 that has received the assignment result AR from the group management control device 20 causes the car 12 to travel toward the call floor Fc. After the process of step S8, the assignment control unit 24 ends the process of this flowchart.

For example, assume that the destination floor registration device 13 of the elevator lobby of 3 floors registers to the destination floor of 5 floors (Fc is 3, Fd is 5). In fig. 1, no 3 floors are set as the power supply floors for any elevators. In addition, since the 5 th floor of the a-car is the non-power supply floor, if the car 12a stops at the 3 rd floor and the 5 th floor in the a-car, the car stops continuously at the non-power supply floor. Here, when the number of consecutive no-power-supply permission times is set to 0, the elevator a is excluded from the allocation candidates. Then, the elevator B and the elevator C of which the 5 floors are the power supply floors are reserved as allocation candidates, and the allocation control unit 24 allocates one of the elevator B and the elevator C to the call of the 3 floors. Here, elevator number C is allocated because elevator number B is in downward service and elevator number C is moving from floor 1 upward with respect to the call of floor 3. The display unit 15 of the 3-floor elevator hall destination floor registration device 13 displays a message for prompting the passenger to take the elevator to the elevator car C.

In addition, even if a 4-floor passenger is registered in the car 12a of the a-number elevator, the car 12a stops at the 4-floor serving as the power supply floor after the 3-floor (non-power supply floor) stops even in response to a call from the 3-floor to the 5-floor, and thus the car does not stop continuously at the non-power supply floor. Therefore, the continuous non-power supply determination unit 234 determines that the elevator a is not stopped continuously, and the elevator a becomes an allocation candidate, and an elevator a having a waiting time shorter than that of the elevator B may be allocated.

According to the first embodiment described above, by controlling to avoid continuous stop of the car 12 on the non-power-feeding layer, the storage capacity of the spare portion, which has conventionally been set to be large due to an indefinite stop time, can be optimized. This can suppress an increase in the storage capacity of the power storage device 33 mounted on the car 12, and can reliably suppress a decrease in the remaining battery power level. As a result, a decrease in service due to a shortage of the battery power level can be suppressed.

For example, since a charging device such as a lithium ion battery is expensive, in recent years, a capacitor type power storage device called a supercapacitor has been used. Capacitor-type power storage devices have a smaller capacity than lithium ion batteries, but are easy to take out electric power, and have a longer life than lithium ion batteries. The present invention is applicable to a power storage device using such a power storage device having a relatively small charge capacity.

Here, the remaining battery level determination unit 21 is provided in the group management control device 20, but the determination may be performed by the elevator control device 11 of any of the elevators a to C, and when the remaining battery level is insufficient, the corresponding elevator control device 11 may notify the group management control device 20 of the exclusion of the allocation.

<2 > second embodiment

The second embodiment is an example in which the number of consecutive no-power-supply permitted times is set for each elevator based on the remaining power level of the power storage device 33 mounted on the car 12 of each elevator.

Fig. 4 is a block diagram showing an example of the internal configuration of the group management control device according to the second embodiment.

The group management control device 20A shown in fig. 4 is configured by adding a consecutive no-power-supply permitted number setting unit 25 and a consecutive stop permitted number table 26 to the group management control device 20 shown in fig. 1.

The continuous non-power-supply permitted number setting unit 25 operates when the battery power level Est of the battery device 33 of the car 12 of each elevator in the battery power level determination unit 21 is equal to or greater than the threshold Eth. The continuous non-power-supply permitted number setting unit 25 refers to the continuous stop permitted number table 26, and dynamically sets a predetermined value of the continuous stop permitted number based on the battery power level of the battery device 33 of the target elevator determined by the battery power level determination unit 21. Then, the continuous non-power-supply permitted number setting unit 25 outputs a predetermined value of the set continuous stop permitted number to the assignment candidate extracting unit 23.

The continuous stop permission count table 26 is a table in which the correspondence relationship between the battery power level Est [% ] of the power storage device 33 and the continuous stop permission count Nm to the non-power supply layer is registered. In fig. 4, the number of consecutive stops Nm is "0" when the battery power level Est [% ] is "Eth% or more and less than 40%", and the number of consecutive stops Nm is "1" when the battery power level Est [% ] is "40% or more and less than 60%". Further, the number of consecutive stops Nm is "2" when the battery power level Est [% ] is "60% or more and less than 80%", and the number of consecutive stops Nm is "3" when the battery power level Est [% ] is "80% or more".

[ procedure for assigning Elevator decision method ]

Fig. 5 is a flowchart showing a procedure of an assigned elevator deciding method in the group management control device 20A.

In fig. 5, the processing of steps S11 and S12 is the same as the processing of steps S1 and S2 in fig. 3, and thus detailed description thereof is omitted.

When the battery power level Est of the power storage device 33 is equal to or greater than the threshold Eth in the determination processing of step S11 (yes in S11), the consecutive non-power-supply permitted number setting unit 25 refers to the consecutive stop permitted number table 26, and dynamically sets a predetermined value of the consecutive stop permitted number based on the battery power level of the power storage device 33 of the target elevator determined by the battery power level determination unit 21 (S13). Then, the continuous non-power-supply permitted number setting unit 25 outputs a predetermined value of the set continuous stop permitted number to the assignment candidate extracting unit 23.

After the process of step S13, each unit of the distribution candidate extracting unit 23 executes the processes of steps S14 to S19. The processing of steps S14 to S19 is the same as the processing of steps S3 to S8 in fig. 3, and thus detailed description thereof is omitted. In step S16, the continuous non-power-supply determination unit 234 determines whether the number of times of continuous stop of the car 12 of the target elevator to the non-power-supply layer exceeds a predetermined number of times of continuous non-power-supply allowance based on the determination result of the call floor Fc in step S14, the determination result of the destination floor Fd in step S15, and the information of the registered destination floors in the registered destination floor list 235. The predetermined value of the number of continuous non-power feeding permission times here is a value dynamically set by the number of continuous non-power feeding permission times setting unit 25 in accordance with the battery power level of the power storage device 33 in step S13. After the process of step S19, the assignment control unit 24 ends the process of this flowchart.

According to the second embodiment described above, in addition to the effects of the first embodiment, the following effects can be obtained. In the second embodiment, the predetermined value of the number of times of continuous no-power supply allowance can be set for each elevator based on the remaining power level of the power storage device 33 mounted on the car 12 of each elevator. This makes it possible to provide an optimal service for each elevator according to the state of the battery power level, for example, to delay the timing of power supply to an elevator having a surplus in battery power level. Further, when the battery power level is small, the timing of power supply can be advanced by reducing the number of times the continuous non-power supply is allowed. This can prevent a long service stop due to the battery power level depletion and the increase in the power supply time, and thus can improve the serviceability.

In the present embodiment, the predetermined value of the number of times of continuous non-power feeding permission is set according to the battery power level, but the predetermined value of the number of times of continuous non-power feeding permission may be set based on the total moving distance when the car 12 continuously moves to the non-power feeding floor. The larger the total moving distance in the case of continuously moving to the non-power supply layer, the more the amount of power consumed, and the reduction in the battery power level can be expected.

<3 > third embodiment

As shown in fig. 6, the third embodiment is an example in which an elevator system is provided with an elevator hall call device 5 and a car destination floor registration device 6 alone in place of the elevator hall destination floor registration device 13.

[ integral Structure of Elevator ]

Fig. 6 is a schematic configuration diagram showing an example of the overall configuration of an elevator system according to a third embodiment.

As shown in fig. 6, the elevator system 1B includes an elevator hall call device 5 in an elevator hall at each floor. In the case of using an elevator at each floor, the elevator hall call device 5 has an up button for directing upward and a down button for directing downward, and the user presses any button. The elevator hall call device 5 outputs a call signal according to the pressed button. A car destination floor registration device 6 is disposed inside the car 12 of each elevator. The destination layer registration is performed by the car destination layer registration device 6 in each car 12. The car destination layer registration device 6 includes an operation unit 62 for specifying a destination layer, and a display unit 63 for displaying the destination layer of the car 12 and the like. In fig. 6, only the car destination floor registration device 6 of the elevator B is shown with reference numerals of the operation unit 62 and the display unit 63.

In addition, stop

limit display portions

7a and 7b are provided in the elevator lobbies at each floor. In fig. 6, the stop limit display part 7a of the elevator a shows the priority floors 2 and 4, and the stop limit display part 7B of the elevator B shows the

priority floors

3 and 5. Thus, the user can determine to board the elevator a when he/she goes to the 2 th floor or the 4 th floor, and can determine to board the elevator B when he/she goes to the 3 rd floor or the 5 th floor. The power supply floors of elevator No. a are floor 1 as a reference floor and floors 2 and 4 that stop preferentially, and the power supply floors of elevator No. B are floor 1 as a reference floor and

floors

3 and 5 that stop preferentially. In addition, the elevator C has all floors set as power supply floors.

Each elevator hall call device 5 transmits information on the floor on which any one of the upper and lower buttons is pressed (call floor Fc) to the group management control device 20B via the communication line. The car destination floor registration device 6 in each car 12 outputs information on the floor designated by the passenger (destination floor Fd) to the car device 34, and the car device 34 transmits the destination floor Fd to each of the elevator control devices 11a to 11c via the communication line. Then, the destination floor Fd specified in the car 12 of each elevator is transmitted from each of the elevator control devices 11a to 11c to the group management control device 20B via the communication line.

[ internal Structure of group management control device ]

Fig. 7 is a block diagram showing an example of the internal configuration of the group management control device 20B.

The group management control device 20B includes: the remaining battery level determining unit 21, the power supply control unit 22, the allocation candidate extracting unit 41, the allocation control unit 24, and the target formation layer receiving unit 42. The remaining battery level determining unit 21 and the power supply control unit 22 are the same as those described in fig. 2, and therefore, description thereof is omitted.

The allocation candidate extraction unit 41 operates when the battery power level Est of the power storage device 33 of the car 12 of each elevator in the battery power level determination unit 21 is equal to or greater than the threshold Eth. The allocation candidate extracting unit 41 extracts, as allocation candidates, elevators for which the number of consecutive stop allowability times of the car 12 to the non-power supply floor is not more than a predetermined value, based on the call floor Fc (call floor information), the power supply floor setting information for each elevator, and the registered destination floor information for each elevator.

The assignment control unit 24 determines an assigned elevator for the call signal (elevator hall call) output from the elevator hall call device 5 from the elevators of the assignment candidates extracted by the assignment candidate extraction unit 41 and registered in the assignment candidate list 236. The assignment control unit 24 outputs the assigned elevator to the corresponding elevator control device 11 as the assignment result AR.

The destination floor receiving unit 42 determines whether or not the car 12 of the assigned elevator assigned by the assignment control unit 24 exceeds a predetermined value of the number of consecutive stop allowability times to the non-power supply floor, based on the information on the destination floor (destination floor registration information) specified by the car destination floor registration device 6, the power supply floor setting information, and the registered destination floor information. Then, the destination floor receiving unit 42 receives destination floor registration information of the target and registers the destination floor of the car 12 when the car 12 to which the elevator is assigned does not exceed a predetermined value of the number of times of continuous stop allowance to the non-power supply floor.

(configuration of allocation candidate extracting section)

Here, the allocation candidate extracting unit 41 will be further described. As shown in fig. 7, the allocation candidate extraction unit 41 includes: a power supply floor setting storage unit 231, an elevator lobby floor power supply determination unit 232, an allocation candidate selection unit 411, a first continuous non-power supply determination unit 412, a registered destination floor list 235, and an allocation candidate list 236.

The allocation candidate selection unit 411 refers to the determination result of the elevator lobby floor power supply determination unit 232 and the power supply floor setting information of the power supply floor setting storage unit 231, and selects (pre-registers) an elevator having a call floor Fc as a power supply floor as an allocation candidate from among elevators satisfying the electric power storage capacity Est ≧ Eth. Then, the selection result is output to the first continuous non-power-supply determining unit 412.

The first continuous non-power-supply determining unit 412 determines whether or not the elevator selected by the allocation candidate selecting unit 411 is to be stopped at a non-power-supply floor, based on the registered destination floor list 235 and the power supply floor setting information of the power supply floor setting storage unit 231. If no stop is scheduled on the non-power supply floor, the corresponding elevator is registered as an allocation candidate for an elevator hall call in the allocation candidate list 236. On the other hand, when the car 12 is scheduled to stop to the non-power supply floor and the number of consecutive stops of the car 12 to the non-power supply floor exceeds the predetermined number of consecutive non-power supply allowances, the elevator is set as the allocation exclusion.

(Structure of target stratum receiving part)

Here, the target formation receiving section 42 will be further described. As shown in fig. 7, the target formation receiving unit 42 includes: the destination power supply determination unit 233, the second continuous non-power supply determination unit 421, the destination registration unit 422, and the destination invalidation processing unit 423.

The destination floor power supply determination unit 233 determines whether the destination floor Fd is a power supply floor or a non-power supply floor when a passenger on the call floor Fc gets on the car 12 of the assigned elevator and the destination floor Fd is registered by the operation unit 62 of the car destination floor registration device 6 in the car 12. Then, the determination result is output to the second continuous non-power-supply determination section 421.

The second continuous non-power-supply determining portion 421 determines whether or not the number of times of continuous stop of the car 12 of the elevator assigned by the assignment control portion 24 to the non-power-supply floor exceeds the number of times of continuous non-power-supply allowance (predetermined value) based on the determination result of the destination-floor-power-supply determining portion 233, the power-supply-floor setting information of the power-supply-floor setting storage portion 231, and the registered destination floor list 235. The second continuous non-power-supply determining section 421 outputs the determination result to the destination layer registering section 422 when the number of times of continuous stop of the car 12 to the non-power-supply layer does not exceed the number of times of continuous non-power-supply allowance, and outputs the determination result to the destination layer disabling processing section 423 when the number of times of continuous stop of the car 12 to the non-power-supply layer exceeds the number of times of continuous non-power-supply allowance.

When the second continuous non-power supply determining portion 421 notifies that the number of times of continuous stop of the car 12 to the non-power supply layer does not exceed the number of times of continuous non-power supply allowance, the destination layer registering portion 422 receives the registration of the input destination layer Fd and continues the operation of the target elevator.

The destination floor invalidation processing unit 423 invalidates the inputted destination floor Fd when the second continuous non-power supply determination unit 421 notifies that the number of times of continuous stop of the car 12 to the non-power supply layer exceeds the number of times of continuous non-power supply allowance. The destination floor invalidation processing unit 423 notifies the car destination floor registration device 6 of the target elevator that the destination floor Fd designated by the passenger is invalid, and displays the notification on the display unit 63. The passenger can confirm that the designated destination layer Fd is invalid (or is not invalid) by viewing the display contents of the display unit 63. The destination floor invalidation processing unit 423 notifies the assignment control unit 24 that the destination floor Fd specified by the passenger in the car destination floor registration device 6 of the target elevator is invalid. The assignment control unit 24 having received the notification performs a process of calling another alternative elevator to the call floor Fc.

[ procedure for assigning Elevator decision method ]

Fig. 8 is a flowchart showing a procedure of an assigned elevator deciding method in the group management control device 20B.

The determination process of step S21 and the process of step S22 in fig. 8 are the same as the determination process of step S1 and the process of step S2 in fig. 3.

Next, in the case of yes at step S21, the elevator lobby floor power supply determination unit 232 of the allocation candidate extraction unit 41 determines whether or not the call floor Fc (elevator lobby floor) is a power supply floor, based on the information on the call floor Fc and the information on the power supply floor of each elevator stored in the power supply floor setting storage unit 231 (S23). Here, when the call layer Fc is the power supply layer (yes in S23), the process proceeds to step S24, and when the call layer Fc is not the power supply layer (no in S23), the process proceeds to step S27. The determination processing of step S23 corresponds to the processing of step S3 of fig. 3.

Next, the allocation candidate selecting unit 411 selects (preliminarily registers) an elevator whose call floor Fc is a power supply floor as an allocation candidate (S24). Then, the selection result is output to the first continuous non-power-supply determining unit 412.

Next, in the first continuous non-power-supply determining unit 412, it is determined whether or not the number of times of continuous stop of the car 12 of the target elevator to the non-power-supply floor exceeds a predetermined number of times of continuous non-power-supply allowance, based on the information of the registered destination floor and the power-supply floor setting information in the registered destination floor list 235, with respect to the elevator selected in step S24 (S25). The determination processing of step S25 is similar to the determination processing of step S5 of fig. 3, but is spare data here.

In the determination processing in step S25, if it is determined that the number of times the car 12 of the target elevator is continuously stopped on the non-power supply floor does not exceed the predetermined number of times of continuous no-power supply allowance (no in S25), the first continuous no-power supply determination unit 412 extracts the target elevator as an allocation candidate and registers the target elevator in the allocation candidate list 236 (S26). On the other hand, when it is determined that the number of times the car 12 of the target elevator is continuously stopped on the non-power supply floor exceeds the predetermined number of times the non-power supply is allowed continuously (yes in S25) or when it is determined that the number of times the car is continuously stopped on the non-power supply floor exceeds the predetermined number of times the non-power supply is allowed continuously (no in step S23), the first continuous non-power supply determination unit 412 excludes the target elevator from the allocation candidates (S27). The processing of steps S26, S27 corresponds to the processing of steps S6, S7 of fig. 3.

Next, after the processing of step S27 or step S28, the assignment control unit 24 determines an assigned elevator for the call signal (elevator hall call of the call floor Fc) from the elevators of the assignment candidates registered in the assignment candidate list 236 according to a predetermined rule, and outputs the determined assigned elevator as the assignment result AR to the corresponding elevator control device 11 (S28). The allocation control unit 24 allocates the service from the allocation candidates in consideration of the short waiting time and the like. The process of step S28 corresponds to the process of step S8 of fig. 3. Then, the elevator control device 11 that has received the assignment result AR from the group management control device 20B causes the car 12 to travel toward the call floor Fc.

For example, when a person on level 1 who gets into the car 12 registers a non-power supply floor by the car destination floor registration device 6, if a passenger on the call floor Fc registers the non-power supply floor as the destination floor Fd getting into the car 12, the non-power supply floor is continuously stopped. The determination processing in step S25 prevents such a situation in which the car 12 is continuously stopped (more than the number of times of continuous non-power supply allowance) to the non-power supply layer.

Next, the destination power supply determining unit 233 of the destination layer receiving unit 42 determines whether or not the destination layer Fd is a power supply layer, based on the information of the destination layer Fd specified by the car destination layer registration device 6 of the car 12 of the elevator to be used and the information of the power supply layer of each elevator stored in the power supply layer setting storage unit 231 (S29). The process of step S29 corresponds to the process of step S4 of fig. 3.

Next, in the second continuous non-power-supply determining portion 421, it is determined whether or not the number of times of continuous stop of the car 12 of the target elevator to the non-power-supply floor exceeds a predetermined number of times of continuous non-power-supply permission, based on the information of the registered destination floor and the power-supply floor setting information in the registered destination floor list 235, with respect to the elevator selected in step S24 (S30). Here, the second continuous non-power-feeding determination unit 421 outputs the determination result to the destination layer registration unit 422 when the number of times of continuous stop of the car 12 to the non-power-feeding layer does not exceed the number of times of continuous non-power-feeding allowance (no in S30). On the other hand, when the number of times the car 12 is continuously stopped on the non-power supply floor exceeds the number of times the power is continuously not supplied (yes in S30), the determination result is output to the destination floor invalidation processing unit 423.

Next, when it is determined that the number of times the car 12 is continuously stopped in the non-power supply floor does not exceed the number of times the power supply is continuously not allowed (no in S30), the destination floor registration unit 422 receives the input registration of the destination floor Fd and continues the operation of the target elevator (S31).

On the other hand, when determining that the number of times the car 12 is continuously stopped on the non-power supply floor exceeds the number of times the non-power supply is continuously allowed (yes in S30), the destination floor invalidation processing unit 423 invalidates the inputted destination floor Fd and displays that the destination floor is invalid on the display unit 63 of the car destination floor registration device 6 of the target elevator (S33).

Next, the destination floor invalidation processing unit 423 notifies the assignment control unit 24 that the destination floor Fd specified by the passenger in the car destination floor registration device 6 of the target elevator is invalid. The assignment control unit 24 that has received the notification that the destination floor is invalid performs a process of placing another alternative elevator call to a floor corresponding to the call floor Fc (S33).

For example, when the destination floor Fd is a non-power supply floor (in this case, a non-priority operation floor), the second continuous non-power supply determining unit 421 determines whether or not the car 12 is continuously stopped at the non-power supply floor beyond the number of times of continuous non-power supply allowance in step S30. If the number of consecutive stop floors to the non-power supply floor exceeds the number of consecutive non-power supply permitted times, the destination floor invalidation processing unit 423 invalidates the destination floor Fd, notifies passengers via the display unit 63, for example, and calls the car 12 of another elevator to the floor.

This makes it possible to suppress a decrease in the battery power level caused by the continuous stop of the power supply to the non-power supply layer beyond the number of times the continuous non-power supply is permitted. In the example of fig. 6, the case of limiting the floors at which the car 12 can stop is shown in advance, and passengers can understand this.

After the processing of step S31 or step S33, the target formation acceptance unit 42 ends the processing of this flowchart.

In addition, in the car destination floor registration device 6 of the elevator in which the stop restriction is performed, only the power supply floor may be selected as the destination floor Fd. However, when continuous stop to the non-power supply layer is limited (the number of times of continuous non-power supply permission corresponds to 0), movement from the power supply layer to the non-power supply layer is permitted without exceeding the continuous stop, and the waiting time is reduced.

In the third embodiment, the same effects as those of the first embodiment can be obtained. That is, even in the elevator system 1B not including the elevator hall destination layer registration device 13, it is possible to suppress continuous stop (exceeding the number of times of continuous non-power supply permission) to the non-power supply layer. This makes it possible to optimize (reduce) the storage capacity of the power storage device 33 mounted on the car 12 and suppress a reduction in service due to a reduction in the remaining battery power.

In the third embodiment described above, the configuration of dynamically setting the predetermined value of the number of times of continuous non-power-supply permission in the second embodiment may be applied.

<4 > variation of the third embodiment

The modification of the third embodiment is an example in which the allocation candidate extracting unit 41 includes an allocation candidate priority setting unit 413 instead of the allocation candidate selecting unit 411 of fig. 7.

[ internal Structure of group management control device ]

Fig. 9 is a block diagram showing an example of the internal configuration of a group management control device 20C according to a modification of the third embodiment. The allocation candidate extracting unit 41A of the group management control device 20C shown in fig. 9 includes an allocation candidate priority setting unit 413 instead of the allocation candidate selecting unit 411 included in the allocation candidate extracting unit 41 of the group management control device 20B shown in fig. 7.

The assignment candidate priority setting unit 413 receives the determination result of the elevator hall floor power supply determination unit 232 and the power supply floor setting information of the power supply floor setting storage unit 231, and gives priority to the elevator as the assignment candidate. In the allocation candidate selection unit 411 of fig. 7, an elevator whose call floor Fc is a power supply floor is selected (preliminary registration) as an allocation candidate, and an elevator which is not a power supply floor is excluded from the allocation candidates. However, the assignment candidate priority setting unit 413 sets a higher priority as an assignment candidate for an elevator whose call floor Fc is a power supply floor, and leaves an elevator that is not a power supply floor as an assignment candidate by giving a lower priority. In this manner, by giving priority to each elevator based on the determination result of whether or not the call floor Fc is the power supply floor, it is possible to flexibly deal with (call the car) various situations.

Fig. 10 is an explanatory diagram showing the priority setting of allocation candidates by the allocation candidate priority setting unit 413 of the group management control device 20C.

An elevator system 1B shown in fig. 10 includes an elevator including a car 12, an elevator control device 11N for controlling the car 12N, and a power transmission unit 31N, and is referred to as an N-number elevator. Regarding the elevator No. N, 1 floor is a power supply floor, 2 floors are non-power supply floors, and 3 to 5 floors are power supply floors. As a premise, the predetermined value of the number of consecutive no-power-supply permission times is set to 0.

The user makes a call at floor 2, and for this purpose, consider the case of the N-th elevator to which the car 12N in which the passenger who takes in from floor 1 is allocated. The car 12n travels from floor 1 to floor 2 without stopping in the middle. When a user rides from the 2-floor, which is a non-power supply floor, and moves to the destination floor Fd of the upper floor, a passenger who has previously entered the car 12 registers a power supply floor located at a higher floor than the destination floor Fd. In this case, when there is no non-power supply floor between the two destination floors or there is no floor in the middle, the non-power supply floor is not continuously stopped. In the case of fig. 10, when a passenger who rides in the car 12 from 1 floor registers any one of the 3 th floor to the 5 th floor as a destination floor, even if a passenger who rides in the 2 nd floor (non-power supply floor) and goes to the upper floor designates an arbitrary destination floor Fd, the continuous stop to the non-power supply floor is not performed. The same idea can be applied to a case where the predetermined value of the number of consecutive times of no-power-supply permission is not 0. Fig. 10 is an example of a case where the call layer Fc is a non-power supply layer, and is not limited to this example.
