Abstract

PROBLEM TO BE SOLVED: To improve a conventional technology, for example, operation during power failure.SOLUTION: An elevator system includes an elevator and a control device. The control device can select a normal operation when a power source for power is sound or a power-failure operation for operating the elevator at a rated speed on a power from a building side power storage device at the time of failure of the power source for power. The control device can select, as the power-failure operation, a power-failure limitless operation or a power-failure limited operation. The power-failure limitless operation performs operation equivalent to the normal operation during a period before minimum operable time lapse for power-failure operation after the power source for power fails. The power-failure limited operation operates by limiting stop floors of the elevator in a case where a remaining power storage amount is an operable power storage amount or more after minimum operable time lapse for power-failure operation.

また、電源制御装置１３は、動力用電源５０からの電力の供給状態に応じてエレベータ１を運転させる電力を適宜切り替えると共に、建物側バッテリ１０２、エレベータ側バッテリ１２の充放電制御を行うことが可能になっている。電源制御装置１３は、少なくとも動力用電源５０、建物側バッテリ１０２、エレベータ側バッテリ１２のいずれかから供給される電力を、エレベータ１を駆動させる電力として使用する。運転制御装置１１は、この電力を用いて各部を作動させ、エレベータ１を運転させる。電源制御装置１３は、例えば、後述するように、動力用電源５０が健全である通常運転時には、カゴ２の移動に使用する電力として、動力用電源５０から供給される電力を主に使用する。このとき、電源制御装置１３は、建物側バッテリ１０２に蓄電されている電力を、動力用電源５０からの電力をアシストする目的で利用することもできる。また、電源制御装置１３は、動力用電源５０の停電時には、カゴ２の移動に使用する電力として、建物側バッテリ１０２、あるいは、エレベータ側バッテリ１２から供給される電力を使用する。また、電源制御装置１３は、エレベータ１の通常運転時に動力用電源５０から供給される電力の一部、通常運転時、停電時のエレベータ１の回生運転時に電動機５ｃによって回生発電された回生電力を利用してエレベータ側バッテリ１２を充電することができる。電源制御装置１３は、通常運転時、停電時のエレベータ１の回生運転時に電動機５ｃによって回生発電された回生電力を利用して建物側バッテリ１０２を充電することも可能である。   The power supply control device 13 can appropriately switch the power for operating the elevator 1 according to the supply state of power from the power source 50 for power, and can perform charge / discharge control of the building-side battery 102 and the elevator-side battery 12. It has become. The power supply control device 13 uses power supplied from at least one of the power source 50 for power, the building-side battery 102 and the elevator-side battery 12 as power for driving the elevator 1. The operation control apparatus 11 operates each part using this electric power, and operates the elevator 1. For example, as will be described later, the power supply control device 13 mainly uses power supplied from the power supply 50 as power used to move the car 2 during normal operation when the power supply 50 is healthy. At this time, the power supply control device 13 can also use the power stored in the building-side battery 102 for the purpose of assisting the power from the power source 50 for power. Moreover, the power supply control apparatus 13 uses the electric power supplied from the building side battery 102 or the elevator side battery 12 as electric power used for the movement of the car 2 at the time of a power failure of the power source 50 for power. Further, the power supply control device 13 uses a part of the power supplied from the power supply 50 during normal operation of the elevator 1, regenerative power generated by the electric motor 5c during regenerative operation of the elevator 1 during normal operation and power failure. The elevator side battery 12 can be charged by using. The power supply control device 13 can also charge the building-side battery 102 using regenerative power generated by the electric motor 5c during regenerative operation of the elevator 1 during normal operation or during a power failure.

In the elevator 1, the operation control device 11 performs the car call registration of the car 2 or the hall call registration according to the car call registration signal and the hall call registration signal. Then, the operation control device 11 can reasonably move the car 2 based on the car call registration, the hall call registration, various sensors, outputs from the detectors, the current moving direction (lifting direction) of the car 2, and the like. However, the landing order of the basket 2 is determined so as to answer each call. Then, the operation control device 11 drives and controls the hoist 5 to move the basket 2 to the target floor. Thus, in the elevator 1, the car 2 moves up and down in the vertical direction in the hoistway 7 and moves to the landing 6 on an arbitrary destination floor. When the elevator 1 detects that the car 2 has landed on the landing 6 on the destination floor and has landed at a predetermined landing position, the operation control device 11 thereafter detects the car 2 and the door 14 of the landing 6. Is released. As a result, a user waiting at the landing 6 can get into the car 2, and a user inside the car 2 can get off at the landing 6.

そして、本実施形態の制御装置１０の運転制御装置１１は、動力用電源５０の停電状態においても、建物側バッテリ１０２によって停電時運転を実行可能である。つまり、本実施形態の制御装置１０は、上記で説明した通常運転と、建物側バッテリ１０２を用いた停電時運転とを切り替えて実行可能である。   And the operation control apparatus 11 of the control apparatus 10 of this embodiment can perform the operation at the time of a power failure by the building side battery 102 even in the power failure state of the power source 50 for power. That is, the control device 10 according to the present embodiment can be executed by switching between the normal operation described above and the operation at the time of power failure using the building-side battery 102.

ここで、通常運転とは、上述のように動力用電源５０の健全時にエレベータ１を定格速度で運転する運転であり、主に動力用電源５０からの電力によってカゴ２を昇降させる運転である。なお、制御装置１０は、当該通常運転では、上述のようにさらに建物側バッテリ１０２の電力をアシスト電力として用いてもよい。制御装置１０は、通常運転時には、エレベータ１と当該エレベータ１が設けられる建物１００での電力使用状態とを連係させて、建物１００の全体で電力のマネージメントを効率的に行い、省エネルギでエレベータ１を運用する。   Here, the normal operation is an operation in which the elevator 1 is operated at a rated speed when the power source 50 is healthy as described above, and is an operation in which the car 2 is moved up and down mainly by the electric power from the power source 50. In the normal operation, the control device 10 may further use the power of the building-side battery 102 as assist power as described above. During normal operation, the control device 10 links the elevator 1 and the power usage state in the building 100 in which the elevator 1 is provided, efficiently manages power in the entire building 100, and saves the elevator 1 with energy saving. Is operated.

一方、停電時運転とは、通常運転とは異なる運転であり、動力用電源５０の停電時の運転である。停電時運転とは、動力用電源５０の停電時に建物側バッテリ１０２からの電力によってエレベータ１を定格速度で運転する運転であり、すなわち、建物側バッテリ１０２を用いてカゴ２を通常運転と同等の定格速度で昇降させる運転である。   On the other hand, the operation at the time of a power failure is an operation different from the normal operation and is an operation at the time of a power failure of the power source 50 for power. The operation at the time of a power failure is an operation in which the elevator 1 is operated at a rated speed by the power from the building-side battery 102 at the time of a power failure of the power source 50, that is, the car 2 is equivalent to the normal operation using the building-side battery 102. It is an operation that moves up and down at the rated speed.

より詳細には、制御装置１０の運転制御装置１１は、停電時運転として、停電時制限無し運転と、停電時制限有り運転とを切り替えて実行可能である。停電時制限無し運転とは、動力用電源５０が停電した後、当該動力用電源５０の停電時の建物側バッテリ１０２の残存蓄電量に基づいた停電時運転可能最低時間経過前の期間に通常運転と同等の運転を行うものである。一方、停電時制限有り運転とは、停電時運転可能最低時間経過後でかつ建物側バッテリ１０２の残存蓄電量が運転可能蓄電量以上である場合に上記停電時制限無し運転と比較してエレベータ１の停止可能階床を制限して運転するものである。   More specifically, the operation control device 11 of the control device 10 can perform switching between an operation without a power failure restriction and an operation with a power failure restriction as a power failure operation. Unrestricted operation at the time of power failure is normal operation during the period before the minimum time that can be operated at the time of power failure based on the remaining power storage amount of the building-side battery 102 at the time of power failure of the power source 50 after power failure of the power source 50 Is equivalent to the operation. On the other hand, the operation with restriction at the time of power failure means that the elevator 1 is compared with the operation without restriction at the time of power failure when the remaining storage amount of the building-side battery 102 is equal to or more than the operable storage amount after the elapse of the minimum operation time at power failure. It is intended to operate with limited floors that can be stopped.

ここで、停電時運転可能最低時間とは、動力用電源５０の停電時の建物側バッテリ１０２の残存蓄電量によって、エレベータ１において定格速度で通常運転と同等の運転を継続することができる最低限の時間に相当する。運転制御装置１１は、典型的には、動力用電源５０の停電時の建物側バッテリ１０２の残存蓄電量と、当該動力用電源５０の停電後に予測される電気設備１０１での消費電力量と、エレベータ１の停電時制限無し運転での消費電力量とに基づいて停電時運転可能最低時間を算出することができる。この場合、運転制御装置１１は、例えば、動力用電源５０が停電した時点で、建物側バッテリ１０２の電流計１０２ａ、電圧計１０２ｂから電源制御装置１３等を介して検出結果を受信する。そして、運転制御装置１１は、当該検出結果に基づいて、建物側バッテリ１０２の電流値、電圧値から建物側バッテリ１０２の残存蓄電量を算出する。動力用電源５０の停電後に予測される電気設備１０１での消費電力量は、予め実験等に応じて算出しておき、運転制御装置１１の記憶部に記憶しておけばよい。また、運転制御装置１１は、通常運転時に電気設備１０１での消費電力量を監視、学習しておき、これに基づいて動力用電源５０の停電後に予測される電気設備１０１での消費電力量を推定してもよい。この場合、運転制御装置１１は、動力用電源５０の停電時に建物１００の最低限の機能を確保するための電気設備１０１（例えば、照明やセキュリティ等）の作動を維持できる程度の消費電力量を推定するようにしてもよい。エレベータ１の停電時制限無し運転での消費電力量は、予め実験等に応じて算出しておき、運転制御装置１１の記憶部に記憶しておけばよい。運転制御装置１１は、例えば、停電時制限無し運転を実行した場合に、建物側バッテリ１０２の残存蓄電量が予め設定される所定パーセンテージになるまでの時間を、停電時運転可能最低時間として算出する。当該所定パーセンテージは、例えば、建物側バッテリ１０２が満充電である状態を１００％とした場合に、運転可能蓄電量に対してマージン等を踏まえて設定されるパーセンテージである。また、上記運転可能蓄電量とは、残存蓄電量に対して設定される蓄電量であり、例えば、実験等に応じて予め設定される。運転可能蓄電量は、カゴ２が意図せず各階床の中間で停止してしまうことなく、所定の昇降行程の昇降を適正に完了するために必要な下限の蓄電量（言い換えれば、ラストランを可能とする最低限の蓄電量）に相当する。   Here, the minimum operable time at the time of a power failure is the minimum that allows the elevator 1 to continue the operation equivalent to the normal operation at the rated speed by the remaining power storage amount of the building-side battery 102 at the time of the power failure. Is equivalent to The operation control device 11 typically has a remaining power storage amount of the building-side battery 102 at the time of a power failure of the power source 50, a power consumption amount of the electrical equipment 101 predicted after a power failure of the power source 50, Based on the power consumption in the unrestricted operation at the time of power failure of the elevator 1, the minimum operable time at the time of power failure can be calculated. In this case, for example, the operation control device 11 receives the detection result from the ammeter 102a and the voltmeter 102b of the building-side battery 102 via the power supply control device 13 or the like when the power source 50 for power supply fails. And the operation control apparatus 11 calculates the remaining electrical storage amount of the building side battery 102 from the electric current value and voltage value of the building side battery 102 based on the said detection result. The power consumption in the electrical equipment 101 predicted after a power failure of the power source 50 may be calculated in advance according to an experiment or the like and stored in the storage unit of the operation control device 11. In addition, the operation control device 11 monitors and learns the power consumption in the electric equipment 101 during normal operation, and based on this, the power consumption in the electric equipment 101 predicted after a power failure of the power source 50 is calculated. It may be estimated. In this case, the operation control device 11 has a power consumption amount sufficient to maintain the operation of the electrical equipment 101 (for example, lighting, security, etc.) for ensuring the minimum function of the building 100 when the power source 50 for power supply is interrupted. You may make it estimate. The power consumption amount of the elevator 1 during the power failure-free operation may be calculated in advance according to an experiment or the like and stored in the storage unit of the operation control device 11. The operation control device 11 calculates, for example, the time until the remaining power storage amount of the building-side battery 102 reaches a predetermined percentage set in advance when the unrestricted operation at the time of a power failure is performed as the minimum operable time at the time of a power failure. . The predetermined percentage is, for example, a percentage that is set in consideration of a margin or the like with respect to the operable power storage amount when the state where the building-side battery 102 is fully charged is 100%. The operable power storage amount is a power storage amount set with respect to the remaining power storage amount, and is set in advance according to, for example, an experiment or the like. The amount of power that can be operated is the minimum amount of electricity required to properly complete the raising and lowering of a predetermined lifting process without the car 2 unintentionally stopping in the middle of each floor (in other words, last run is possible) Equivalent to the minimum charged amount).

運転制御装置１１は、動力用電源５０が停電した場合、電源制御装置１３の制御により電源系統が切り替えられて、通常運転から停電時運転に切り替える。このとき、運転制御装置１１は、上述のように停電時運転可能最低時間を算出し、停電時運転可能最低時間経過前の期間においては、定格速度で停電時制限無し運転を行う。すなわち、この場合、運転制御装置１１は、エレベータ１の停止可能階床を制限せず、通常運転と同等の運転を行う。   When the power supply 50 for power failure causes a power failure, the operation control device 11 switches from the normal operation to the power failure operation by switching the power supply system under the control of the power supply control device 13. At this time, the operation control device 11 calculates the minimum operation possible time at the time of power failure as described above, and performs unrestricted operation at the time of the power failure at the rated speed in the period before the minimum operation possible time at the time of power failure. That is, in this case, the operation control device 11 does not restrict the stoppable floor of the elevator 1 and performs an operation equivalent to the normal operation.

そして、運転制御装置１１は、停電時運転可能最低時間経過後でかつ建物側バッテリ１０２の残存蓄電量が運転可能蓄電量以上である場合に、停電時運転を、停電時制限無し運転から停電時制限有り運転に切り替える。すなわち、この場合、運転制御装置１１は、定格速度でエレベータ１を運転すると共に、エレベータ１の停止可能階床を制限し、通常運転、停電時制限無し運転と比較して制限された運転を行う。この場合、運転制御装置１１は、例えば、予め設定された停止禁止階にはカゴ２を停止させないようにする。ここでは、運転制御装置１１は、停電時制限有り運転では、例えば、停止可能階床以外の階床（停止禁止階）へのカゴ呼び、停止可能階床以外の階床での乗場呼び、及び、停止可能階床での所定方向以外の乗場呼びを無効とする。運転制御装置１１は、例えば、停止可能階床での所定方向以外の乗場呼びとして、基準階方向以外の乗場呼びを無効とする。このようにして、運転制御装置１１は、通常運転、停電時制限無し運転と比較して制限された停電時制限有り運転を行う。   Then, the operation control device 11 performs the operation at the time of the power failure from the operation without the restriction at the time of the power failure when the remaining power storage amount of the building-side battery 102 is equal to or greater than the operationable power storage amount after the elapse of the minimum operable time at the time of the power failure. Switch to limited operation. That is, in this case, the operation control device 11 operates the elevator 1 at the rated speed, restricts the floor where the elevator 1 can be stopped, and performs a limited operation as compared with the normal operation and the unrestricted operation during power failure. . In this case, for example, the operation control device 11 does not stop the basket 2 at a preset stop prohibited floor. Here, the operation control device 11 performs, for example, a call to a floor other than the stoppable floor (stop prohibited floor), a hall call on a floor other than the stoppable floor, Any hall call other than the specified direction on the stoppable floor is invalidated. For example, the operation control device 11 invalidates the hall call other than the reference floor direction as the hall call other than the predetermined direction on the stoppable floor. In this manner, the operation control device 11 performs the limited operation at the time of power failure that is limited compared to the normal operation and the operation without limitation at the time of power failure.

ここで、上記基準階とは、このエレベータ１におけるサービスの基準となる階床であり、例えば、エントランス等が存在するロビー階等である。停止可能階床、及び、停止禁止階は、予め設定されてもよいし、防災センタや管理人室の監視装置から任意に設定できるようにしてもよい。例えば、建物１００が高層の建築物である場合、停止可能階床は、高層階に設定され、停止禁止階は、基準階（例えば、１階）を除いた低層階に設定されてもよい。   Here, the reference floor is a floor serving as a service reference in the elevator 1, and is, for example, a lobby floor where an entrance or the like exists. The stoppable floor and the stop prohibition floor may be set in advance, or may be arbitrarily set from the monitoring device of the disaster prevention center or the manager room. For example, when the building 100 is a high-rise building, the stoppable floor may be set as a high-rise floor, and the stop-prohibited floor may be set as a low-rise floor excluding a reference floor (for example, the first floor).

この結果、このエレベータシステム１Ａは、動力用電源５０が停電しても、建物側バッテリ１０２の電力によって停電時制限無し運転を行うことで、エレベータ１において定格速度で通常運転と同様のサービスを継続することができる。そして、エレベータシステム１Ａは、動力用電源５０が停電した後、停電時運転可能最低時間が経過すると、建物側バッテリ１０２の残存蓄電量が運転可能蓄電量以上である場合には、エレベータ１を停電時制限無し運転から停電時制限有り運転に切り替える。これにより、エレベータシステム１Ａは、動力用電源５０が停電している状態で、建物側バッテリ１０２の電力によって停電時制限有り運転を行うことで、停止可能階床をサービス性が優先される階床（例えば、高層階）に制限してサービスを継続することができる。したがって、エレベータシステム１Ａは、動力用電源５０の停電時においても、階段を利用しての移動が大変になる高層階等の階床へのサービス性を可能な限り損なわないような運転を実現することができる。よって、エレベータシステム１Ａは、停電時の運転を適正に行うことができる。   As a result, this elevator system 1A continues the same service as the normal operation at the rated speed in the elevator 1 by performing the unrestricted operation at the time of the power failure by the power of the building-side battery 102 even if the power source 50 for the power supply fails. can do. Then, after the power supply 50 for power failure, the elevator system 1A powers off the elevator 1 when the remaining power storage capacity of the building-side battery 102 is equal to or greater than the drive power storage capacity after the minimum operating time during power failure elapses. Switch from operation without time limit to operation with time limit. As a result, the elevator system 1A performs a limited operation at the time of a power failure by the power of the building-side battery 102 in a state where the power source 50 is in a power failure. The service can be continued by limiting to (for example, higher floors). Therefore, the elevator system 1A realizes an operation that does not impair serviceability to a floor such as a higher floor where movement using the stairs becomes difficult even during a power failure of the power supply 50. be able to. Therefore, the elevator system 1A can appropriately perform the operation at the time of a power failure.

またさらに、本実施形態の運転制御装置１１は、動力用電源５０の停電状態において、上記建物側バッテリ１０２の残存蓄電量が運転可能蓄電量未満となった際に、建物側バッテリ１０２によって停電時継続運転を実行可能である。   Furthermore, the operation control device 11 of the present embodiment is configured such that when the remaining power storage amount of the building side battery 102 becomes less than the operable power storage amount in the power failure state of the power source 50, the building side battery 102 causes a power failure. Continuous operation can be executed.

ここで、停電時継続運転とは、通常運転や停電時運転とは異なる運転であり、動力用電源５０の停電時の運転である。停電時継続運転とは、動力用電源５０の停電時にエレベータ側バッテリ１２からの電力によってエレベータ１を定格速度より低速で運転する運転である。これにより、エレベータ１は、停電時継続運転において、通常運転や停電時運転の場合と比較して、電動機５ｃの負荷を抑制し、電力使用量を抑制してカゴ２の昇降を継続することができる。   Here, the continuous operation at the time of a power failure is an operation different from the normal operation or the operation at the time of a power failure, and is an operation at the time of a power failure of the power source 50 for power. The continuous operation at the time of a power failure is an operation in which the elevator 1 is operated at a speed lower than the rated speed by the electric power from the elevator-side battery 12 when the power source 50 is powered down. Thereby, in the continuous operation at the time of power failure, the elevator 1 can suppress the load on the electric motor 5c and continue to raise and lower the car 2 while suppressing the amount of electric power used as compared with the case of normal operation or operation at the time of power failure. it can.

より詳細には、制御装置１０の運転制御装置１１は、停電時継続運転として、停電時継続制限無し運転と、停電時継続制限有り運転とを切り替えて実行可能である。停電時継続制限無し運転とは、動力用電源５０の停電時に、建物側バッテリ１０２の残存蓄電量が運転可能蓄電量未満となった後、停電時継続運転可能最低時間経過前の期間に停止可能階床を制限しないで運転を行うものである。一方、停電時継続制限有り運転とは、停電時継続運転可能最低時間経過後でかつエレベータ側バッテリ１２の残存蓄電量が運転可能蓄電量以上である場合に停電時継続制限無し運転と比較してエレベータ１の停止可能階床を制限して運転するものである。   More specifically, the operation control device 11 of the control device 10 can perform switching between a continuous operation without a power failure restriction operation and a continuous operation with a power failure restriction operation as a continuous operation during a power failure. Operation without continuation restriction during power failure means that the power can be stopped in the period before the minimum time that can be continuously operated during power failure after the remaining amount of power stored in the building-side battery 102 becomes less than the amount of operable power during power failure Driving without restricting the floor. On the other hand, the operation with continuous restriction during power failure is compared with the operation without continuous restriction during power failure when the remaining power storage capacity of the elevator-side battery 12 is equal to or greater than the operable power storage capacity after the elapse of the minimum time for continuous operation during power failure. The elevator 1 is operated with the stoppable floors restricted.

ここで、停電時継続運転可能最低時間とは、建物側バッテリ１０２の残存蓄電量が運転可能蓄電量未満となった時のエレベータ側バッテリ１２の残存蓄電量に基づいた時間である。停電時継続運転可能最低時間とは、建物側バッテリ１０２の残存蓄電量が運転可能蓄電量未満となった時のエレベータ側バッテリ１２の残存蓄電量によって、定格速度より低速で全ての階床を停止可能階床として運転を継続することができる最低限の時間に相当する。運転制御装置１１は、典型的には、建物側バッテリ１０２の残存蓄電量が運転可能蓄電量未満となった時のエレベータ側バッテリ１２の残存蓄電量と、エレベータ１の停電時継続制限無し運転での消費電力量とに基づいて停電時継続運転可能最低時間を算出することができる。この場合、運転制御装置１１は、例えば、建物側バッテリ１０２の残存蓄電量が運転可能蓄電量未満となった時点で、エレベータ側バッテリ１２の電流計１２ａ、電圧計１２ｂから電源制御装置１３等を介して検出結果を受信する。そして、運転制御装置１１は、当該検出結果に基づいて、エレベータ側バッテリ１２の電流値、電圧値からエレベータ側バッテリ１２の残存蓄電量を算出する。エレベータ１の停電時継続制限無し運転での消費電力量は、予め実験等に応じて算出しておき、運転制御装置１１の記憶部に記憶しておけばよい。運転制御装置１１は、例えば、停電時継続制限無し運転を実行した場合に、エレベータ側バッテリ１２の残存蓄電量が予め設定される所定パーセンテージになるまでの時間を、停電時継続運転可能最低時間として算出する。当該所定パーセンテージは、例えば、エレベータ側バッテリ１２が満充電である状態を１００％とした場合に、運転可能蓄電量に対してマージン等を踏まえて設定されるパーセンテージである。また、上記運転可能蓄電量とは、上記と同様に、残存蓄電量に対して設定される蓄電量であり、例えば、実験等に応じて予め設定される。   Here, the minimum allowable continuous operation time during a power failure is a time based on the remaining storage amount of the elevator-side battery 12 when the remaining storage amount of the building-side battery 102 becomes less than the operable storage amount. The minimum time for continuous operation during a power failure is that all floors are stopped at a speed lower than the rated speed, depending on the remaining storage amount of the elevator-side battery 12 when the remaining storage amount of the building-side battery 102 becomes less than the operable storage amount. This corresponds to the minimum time during which operation can be continued as a possible floor. Typically, the operation control device 11 is configured to operate with no remaining power storage of the elevator-side battery 12 when the remaining power storage amount of the building-side battery 102 is less than the operable power storage amount, and operation without continuation restriction during a power failure of the elevator 1. It is possible to calculate the minimum time that can be continuously operated during a power failure based on the amount of power consumption. In this case, for example, the operation control device 11 changes the power control device 13 from the ammeter 12a and the voltmeter 12b of the elevator-side battery 12 when the remaining power storage amount of the building-side battery 102 becomes less than the operable power storage amount. The detection result is received via And the operation control apparatus 11 calculates the remaining electrical storage amount of the elevator side battery 12 from the electric current value and voltage value of the elevator side battery 12 based on the said detection result. The power consumption of the elevator 1 during operation without a continuous restriction during a power failure may be calculated in advance according to an experiment or the like and stored in the storage unit of the operation control device 11. For example, when the operation control device 11 performs an operation without continuous restriction at the time of a power failure, the time until the remaining power storage amount of the elevator-side battery 12 reaches a predetermined percentage set in advance is set as the minimum time that can be continuously operated at the time of a power failure. calculate. The predetermined percentage is, for example, a percentage that is set based on a margin or the like with respect to the operable power storage amount when the state where the elevator-side battery 12 is fully charged is 100%. The operable power storage amount is a power storage amount set with respect to the remaining power storage amount as described above, and is set in advance according to, for example, an experiment or the like.

運転制御装置１１は、動力用電源５０が停電した後、停電時運転で建物側バッテリ１０２の残存蓄電量が運転可能蓄電量未満となった場合、電源制御装置１３の制御により電源系統が切り替えられて、停電時運転から停電時継続運転に切り替える。このとき、運転制御装置１１は、上述のように停電時継続運転可能最低時間を算出し、停電時継続運転可能最低時間経過前の期間においては、定格速度より低速で停電時継続制限無し運転を行う。すなわち、この場合、運転制御装置１１は、エレベータ１の停止可能階床を制限せずに運転を行う。   The operation control device 11 switches the power supply system under the control of the power supply control device 13 when the remaining power storage amount of the building-side battery 102 becomes less than the operable power storage amount after the power supply 50 for power failure. Switch from operation at power failure to continuous operation at power failure. At this time, the operation control device 11 calculates the minimum time that can be continuously operated during a power failure as described above, and performs an operation without continuous restriction during a power failure at a speed lower than the rated speed in the period before the minimum time that allows continuous operation during a power failure. Do. That is, in this case, the operation control device 11 operates without restricting the stoppable floor of the elevator 1.

そして、運転制御装置１１は、停電時継続運転可能最低時間経過後でかつエレベータ側バッテリ１２の残存蓄電量が運転可能蓄電量以上である場合に、停電時継続運転を、停電時継続制限無し運転から停電時継続制限有り運転に切り替える。すなわち、この場合、運転制御装置１１は、定格速度より低速でエレベータ１を運転すると共に、エレベータ１の停止可能階床を制限し、停電時継続制限無し運転と比較して制限された運転を行う。この場合、運転制御装置１１は、例えば、予め設定された停止禁止階にはカゴ２を停止させないようにする。ここでは、運転制御装置１１は、停電時継続制限有り運転では、停電時制限有り運転と同様に、例えば、停止可能階床以外の階床（停止禁止階）へのカゴ呼び、停止可能階床以外の階床での乗場呼び、及び、停止可能階床での所定方向以外の乗場呼びを無効とする。このときの停止可能階床、及び、停止禁止階は、停電時制限有り運転の場合と同様の階床に設定されてもよいし、停電時制限有り運転の場合とは異なる階床に設定されてもよい。このようにして、運転制御装置１１は、停電時継続制限無し運転と比較して、さらに制限された停電時継続制限有り運転を行う。   Then, the operation control device 11 performs the continuous operation at the time of a power failure and the operation without the continuous restriction at the time of a power failure when the remaining power storage amount of the elevator-side battery 12 is equal to or greater than the operable power storage amount after the elapse of the minimum allowable continuous operation time at the time of a power failure. Switch to operation with continuous restriction during power failure. That is, in this case, the operation control device 11 operates the elevator 1 at a speed lower than the rated speed, limits the stoppable floor of the elevator 1, and performs a limited operation as compared to the operation without continuous restriction during power failure. . In this case, for example, the operation control device 11 does not stop the basket 2 at a preset stop prohibited floor. Here, the operation control device 11 performs, for example, a car call to a floor other than a stoppable floor (stop prohibited floor), a stoppable floor in the operation with a continuous restriction during a power failure, as in the limited operation during a power failure. A hall call on a floor other than the above and a hall call other than a predetermined direction on a stoppable floor are invalidated. The floors that can be stopped and the floors that are prohibited to stop at this time may be set to the same floors as in the case of operation with restrictions during power failure, or different from those in the case of operation with restrictions during power failure. May be. In this way, the operation control device 11 performs a further limited operation at the time of a power failure, compared to the operation without a continuous limitation at the time of a power failure.

このエレベータシステム１Ａは、動力用電源５０が停電した後、停電時運転で建物側バッテリ１０２の残存蓄電量が運転可能蓄電量未満となった場合でも、エレベータ側バッテリ１２の電力によって停電時継続制限無し運転を行う。この結果、このエレベータシステム１Ａは、エレベータ１において定格速度より低速であるものの、全階床を停止可能階床としてサービスを継続することができる。そして、エレベータシステム１Ａは、停電時継続運転可能最低時間が経過すると、エレベータ側バッテリ１２の残存蓄電量が運転可能蓄電量以上である場合には、エレベータ１を停電時継続制限無し運転から停電時継続制限有り運転に切り替える。これにより、エレベータシステム１Ａは、エレベータ側バッテリ１２の電力によって停電時継続制限有り運転を行うことで、停止可能階床をサービス性が優先される階床（例えば、高層階）に制限してサービスを継続することができる。したがって、エレベータシステム１Ａは、動力用電源５０の停電後、建物側バッテリ１０２の残存蓄電量がなくなった場合でも、階段を利用しての移動が大変になる高層階等の階床へのサービス性を可能な限り損なわないような運転を実現することができる。この結果、エレベータシステム１Ａは、動力用電源５０の停電時に、建物側バッテリ１０２の電力、及び、エレベータ側バッテリ１２の電力を計画的に利用し、停電時の運転を適正に行うことができる。   This elevator system 1 </ b> A is configured to limit the continuation during power failure by the power of the elevator side battery 12 even when the remaining power storage amount of the building-side battery 102 becomes less than the operable power storage amount after a power failure of the power supply 50. Run without operation. As a result, although this elevator system 1A is slower than the rated speed in the elevator 1, the service can be continued with all the floors being stoppable floors. Then, when the minimum amount of time that can be continuously operated during a power failure has elapsed, the elevator system 1A causes the elevator 1 to operate at the time of a power failure from operation without continuous restriction during a power failure when the remaining power storage amount of the elevator-side battery 12 is equal to or greater than the operable power storage amount. Switch to operation with continuous restriction. As a result, the elevator system 1A performs the operation with limited continuation during power failure by the power of the elevator-side battery 12, thereby limiting the stoppable floor to a floor (for example, a higher floor) where serviceability is given priority. Can continue. Therefore, the elevator system 1A provides serviceability to floors such as higher floors that make it difficult to move using stairs even if the remaining power storage capacity of the building-side battery 102 is lost after a power failure of the power supply 50. It is possible to realize an operation that does not impair as much as possible. As a result, the elevator system 1A can systematically use the power of the building-side battery 102 and the power of the elevator-side battery 12 at the time of a power failure of the power source 50, and appropriately perform the operation at the time of the power failure.

一例として、エレベータシステム１Ａは、例えば、図２に例示するように、通常運転、停電時運転、及び、停電時継続運転を使い分けることができる。図２の例では、エレベータシステム１Ａは、通常運転においては、動力用電源５０や建物側バッテリ１０２を用いて、定格速度で全階床（ここでは１階から９階）を停止可能階床（サービス階）としてエレベータ１の運転を行う。この場合、エレベータシステム１Ａは、全階床へのカゴ呼び、全階床での乗場呼びを有効とする。また、エレベータシステム１Ａは、停電時運転の停電時制限無し運転においては、建物側バッテリ１０２を用いて、定格速度で全階床（ここでは１階から９階）を停止可能階床としてエレベータ１の運転を行う。この場合も、エレベータシステム１Ａは、全階床へのカゴ呼び、全階床での乗場呼びを有効とする。一方、エレベータシステム１Ａは、停電時運転の停電時制限有り運転においては、建物側バッテリ１０２を用いて、定格速度で停止可能階床を制限してエレベータ１の運転を行う。この場合、エレベータシステム１Ａは、停止可能階床以外の階床（ここでは、２階から５階）へのカゴ呼び、停止可能階床以外の階床での乗場呼び、及び、停止可能階床での所定方向（ここでは基準階である１階に向う方向）以外の乗場呼びを無効とする。さらに、エレベータシステム１Ａは、停電時継続運転の停電時継続制限無し運転においては、エレベータ側バッテリ１２を用いて、定格速度より低速で全階床（ここでは１階から９階）を停止可能階床としてエレベータ１の運転を行う。この場合、エレベータシステム１Ａは、全階床へのカゴ呼び、全階床での乗場呼びを有効とする。一方、エレベータシステム１Ａは、停電時継続運転の停電時継続制限有り運転においては、エレベータ側バッテリ１２を用いて、定格速度より低速で停止可能階床を制限してエレベータ１の運転を行う。この場合、エレベータシステム１Ａは、停止可能階床以外の階床（ここでは、２階から５階）へのカゴ呼び、停止可能階床以外の階床での乗場呼び、及び、停止可能階床での所定方向（ここでは基準階である１階に向う方向）以外の乗場呼びを無効とする。   As an example, as illustrated in FIG. 2, for example, the elevator system 1 </ b> A can properly use normal operation, operation during a power failure, and continuous operation during a power failure. In the example of FIG. 2, the elevator system 1 </ b> A can stop all the floors (here, the first floor to the ninth floor) at the rated speed using the power source 50 for power and the building-side battery 102 in normal operation ( The elevator 1 is operated as a service floor. In this case, the elevator system 1A validates the car call to all floors and the hall call on all floors. Further, the elevator system 1A uses the building-side battery 102 to operate all floors (here, from the first floor to the ninth floor) at a rated speed as a floor that can be stopped by using the building-side battery 102 in the operation at the time of a power failure. Do the operation. Also in this case, the elevator system 1A validates the car call to all floors and the hall call on all floors. On the other hand, the elevator system 1A operates the elevator 1 by restricting the stopable floor at the rated speed by using the building-side battery 102 in the operation with a limit during a power failure. In this case, the elevator system 1A calls for a car to a floor other than the stoppable floor (here, 2nd to 5th floors), a hall call on a floor other than the stoppable floor, and a stoppable floor. A hall call other than a predetermined direction at (in this case, the direction toward the first floor as the reference floor) is invalidated. Further, the elevator system 1A can stop all floors (here, the first floor to the ninth floor) at a speed lower than the rated speed using the battery 12 on the elevator side in the continuous operation without a power failure during a power failure. The elevator 1 is operated as a floor. In this case, the elevator system 1A validates the car call to all floors and the hall call on all floors. On the other hand, the elevator system 1 </ b> A operates the elevator 1 by using the elevator-side battery 12 to limit the stoppable floor at a speed lower than the rated speed in the operation with continuous restriction during a power failure. In this case, the elevator system 1A calls for a car to a floor other than the stoppable floor (here, 2nd to 5th floors), a hall call on a floor other than the stoppable floor, and a stoppable floor. A hall call other than a predetermined direction at (in this case, the direction toward the first floor as the reference floor) is invalidated.

次に、図３のフローチャートを参照して制御装置１０による制御の一例、ここでは、動力用電源５０の停電時の制御の一例を説明する。なお、これらの制御ルーチンは、数ｍｓないし数十ｍｓ毎の制御周期で繰り返し実行される。   Next, an example of control by the control device 10, here, an example of control during a power failure of the power source 50 will be described with reference to the flowchart of FIG. 3. Note that these control routines are repeatedly executed at a control cycle of several ms to several tens of ms.

まず、制御装置１０の電源制御装置１３は、動力用電源５０の作動状態に基づいて、動力用電源５０が停電したか否かを判定する（ステップＳＴ１）。制御装置１０は、電源制御装置１３により動力用電源５０が健全であると判定された場合（ステップＳＴ１：Ｎｏ）、現在の制御周期を終了し、次の制御周期に移行する。   First, the power supply control device 13 of the control device 10 determines whether or not the power supply 50 has failed due to the operating state of the power supply 50 (step ST1). When the power supply control device 13 determines that the power supply 50 is healthy (step ST1: No), the control device 10 ends the current control cycle and shifts to the next control cycle.

制御装置１０の運転制御装置１１は、電源制御装置１３により動力用電源５０の停電が復旧したと判定された場合（ステップＳＴ１：Ｙｅｓ）、停電時運転可能最低時間を算出する（ステップＳＴ２）。この場合、運転制御装置１１は、建物側バッテリ１０２の電流計１０２ａ、電圧計１０２ｂから電源制御装置１３等を介して検出結果を受信し、建物側バッテリ１０２の残存蓄電量等に基づいて停電時運転可能最低時間を算出する。   When it is determined by the power supply control device 13 that the power failure of the power source 50 has been restored (step ST1: Yes), the operation control device 11 of the control device 10 calculates the minimum operable time during a power failure (step ST2). In this case, the operation control device 11 receives the detection result from the ammeter 102a and the voltmeter 102b of the building-side battery 102 via the power supply control device 13 and the like, and at the time of a power failure based on the remaining charged amount of the building-side battery 102, etc. Calculate the minimum operating time.

次に、運転制御装置１１は、電源制御装置１３の制御により電源系統を切り替えて、通常運転から建物側バッテリ１０２を用いた停電時制限無し運転に切り替える（ステップＳＴ３）。   Next, the operation control device 11 switches the power supply system under the control of the power supply control device 13, and switches from normal operation to unrestricted operation during power failure using the building-side battery 102 (step ST3).

次に、運転制御装置１１は、動力用電源５０の停電後、ステップＳＴ３で算出した停電時運転可能最低時間が経過したか否かを判定する（ステップＳＴ４）。運転制御装置１１は、停電時運転可能最低時間が経過していないと判定した場合（ステップＳＴ４：Ｎｏ）、ステップＳＴ３の処理に移行し、以降の処理を繰り返し実行する。   Next, after the power failure of the power source 50, the operation control device 11 determines whether or not the minimum operable time during a power failure calculated in step ST3 has elapsed (step ST4). If the operation control device 11 determines that the minimum operable time during a power failure has not elapsed (step ST4: No), the operation control device 11 proceeds to the process of step ST3 and repeatedly executes the subsequent processes.

運転制御装置１１は、停電時運転可能最低時間が経過したと判定した場合（ステップＳＴ４：Ｙｅｓ）、建物側バッテリ１０２の残存蓄電量が運転可能蓄電量以上であるか否かを判定する（ステップＳＴ５）。この場合、運転制御装置１１は、再度、建物側バッテリ１０２の電流計１０２ａ、電圧計１０２ｂから電源制御装置１３等を介して検出結果を受信し、建物側バッテリ１０２の残存蓄電量を算出する。   If the operation control device 11 determines that the minimum operable time during a power failure has elapsed (step ST4: Yes), the operation control device 11 determines whether or not the remaining charged amount of the building-side battery 102 is greater than or equal to the operable charge amount (step). ST5). In this case, the operation control device 11 again receives the detection result from the ammeter 102a and the voltmeter 102b of the building-side battery 102 via the power supply control device 13 and the like, and calculates the remaining charged amount of the building-side battery 102.

運転制御装置１１は、建物側バッテリ１０２の残存蓄電量が運転可能蓄電量以上であると判定した場合（ステップＳＴ５：Ｙｅｓ）、停電時制限無し運転から停電時制限有り運転に切り替える（ステップＳＴ６）。その後、運転制御装置１１は、ステップＳＴ５の処理に移行し、以降の処理を繰り返し実行する。   If the operation control device 11 determines that the remaining power storage amount of the building-side battery 102 is greater than or equal to the driveable power storage amount (step ST5: Yes), the operation control device 11 switches from the unrestricted operation during power failure to the operation with power failure limitation (step ST6). . Then, the operation control apparatus 11 transfers to the process of step ST5, and performs the subsequent processes repeatedly.

運転制御装置１１は、建物側バッテリ１０２の残存蓄電量が運転可能蓄電量未満であると判定した場合（ステップＳＴ５：Ｎｏ）、停電時継続運転可能最低時間を算出する（ステップＳＴ７）。この場合、運転制御装置１１は、エレベータ側バッテリ１２の電流計１２ａ、電圧計１２ｂから電源制御装置１３等を介して検出結果を受信し、エレベータ側バッテリ１２の残存蓄電量等に基づいて停電時継続運転可能最低時間を算出する。   If the operation control device 11 determines that the remaining power storage amount of the building-side battery 102 is less than the driveable power storage amount (step ST5: No), the operation control device 11 calculates the minimum continuous operation time during a power failure (step ST7). In this case, the operation control device 11 receives the detection result from the ammeter 12a and the voltmeter 12b of the elevator side battery 12 via the power supply control device 13 and the like, and at the time of power failure based on the remaining storage amount of the elevator side battery 12 and the like. Calculate the minimum continuous operation time.

次に、運転制御装置１１は、電源制御装置１３の制御により電源系統を切り替えて、建物側バッテリ１０２を用いた停電時運転からエレベータ側バッテリ１２を用いた停電時継続制限無し運転に切り替える（ステップＳＴ８）。   Next, the operation control device 11 switches the power supply system under the control of the power supply control device 13 to switch from the operation at the time of power failure using the building-side battery 102 to the operation without continuous restriction at the time of power failure using the elevator-side battery 12 (step) ST8).

次に、運転制御装置１１は、建物側バッテリ１０２の残存蓄電量が運転可能蓄電量未満になった後、ステップＳＴ７で算出した停電時継続運転可能最低時間が経過したか否かを判定する（ステップＳＴ９）。運転制御装置１１は、停電時継続運転可能最低時間が経過していないと判定した場合（ステップＳＴ９：Ｎｏ）、ステップＳＴ８の処理に移行し、以降の処理を繰り返し実行する。   Next, after the remaining storage amount of the building-side battery 102 becomes less than the operable storage amount, the operation control device 11 determines whether or not the minimum time for continuous operation during a power failure calculated in step ST7 has elapsed ( Step ST9). If the operation control device 11 determines that the minimum time for continuous operation during a power failure has not elapsed (step ST9: No), the operation control device 11 proceeds to the process of step ST8 and repeatedly executes the subsequent processes.

運転制御装置１１は、停電時継続運転可能最低時間が経過したと判定した場合（ステップＳＴ９：Ｙｅｓ）、エレベータ側バッテリ１２の残存蓄電量が運転可能蓄電量以上であるか否かを判定する（ステップＳＴ１０）。この場合、運転制御装置１１は、再度、エレベータ側バッテリ１２の電流計１２ａ、電圧計１２ｂから電源制御装置１３等を介して検出結果を受信し、エレベータ側バッテリ１２の残存蓄電量を算出する。   If the operation control device 11 determines that the minimum allowable continuous operation time has elapsed during a power failure (step ST9: Yes), the operation control device 11 determines whether the remaining power storage amount of the elevator-side battery 12 is equal to or greater than the driveable power storage amount ( Step ST10). In this case, the operation control device 11 again receives the detection result from the ammeter 12a and the voltmeter 12b of the elevator side battery 12 via the power control device 13 and the like, and calculates the remaining charged amount of the elevator side battery 12.

運転制御装置１１は、エレベータ側バッテリ１２の残存蓄電量が運転可能蓄電量以上であると判定した場合（ステップＳＴ１０：Ｙｅｓ）、停電時継続制限無し運転から停電時継続制限有り運転に切り替える（ステップＳＴ１１）。その後、運転制御装置１１は、ステップＳＴ１０の処理に移行し、以降の処理を繰り返し実行する。   If the operation control device 11 determines that the remaining power storage amount of the elevator-side battery 12 is equal to or greater than the driveable power storage amount (step ST10: Yes), the operation control device 11 switches from the operation without continuation restriction during power failure to the operation with continuation limitation during power failure (step). ST11). Then, the operation control apparatus 11 transfers to the process of step ST10, and performs the subsequent processes repeatedly.

運転制御装置１１は、エレベータ側バッテリ１２の残存蓄電量が運転可能蓄電量未満であると判定した場合（ステップＳＴ１０：Ｎｏ）、カゴ２を最寄階に停止させ停電時継続運転を終了し、現在の制御周期を終了して、次の制御周期に移行する。   When it is determined that the remaining storage amount of the elevator-side battery 12 is less than the operable storage amount (step ST10: No), the operation control device 11 stops the car 2 at the nearest floor and ends the continuous operation during a power failure. End the current control cycle, and shift to the next control cycle.

運転制御装置１１は、動力用電源５０が停電から復旧した場合には、電源制御装置１３の制御により電源系統を切り替えて、エレベータ１を通常運転に復帰させる。   When the power supply 50 for power is restored from the power failure, the operation control device 11 switches the power supply system under the control of the power supply control device 13 and returns the elevator 1 to the normal operation.

なお、上述の制御装置１０は、動力用電源５０の停電後から建物側バッテリ１０２を用いた停電時運転が作動するまでの期間にエレベータ側バッテリ１２を用いた停電時継続運転を実行可能である。例えば、上述のエレベータシステム１Ａは、動力用電源５０が停電した後、停電時運転可能最低時間を算出するために一定時間を要する場合がある。この場合、制御装置１０は、動力用電源５０の停電の直後は、一旦、エレベータ側バッテリ１２を用いて停電時継続制限無し運転を行い、停電時運転可能最低時間の算出完了後に建物側バッテリ１０２を用いた停電時制限無し運転を行うようにしてもよい。これにより、エレベータシステム１Ａは、動力用電源５０の停電の直後もすぐにサービスを継続することができる。   In addition, the above-mentioned control apparatus 10 can perform the continuous operation at the time of a power failure using the elevator side battery 12 in the period from after the power failure of the power source 50 to the operation at the time of a power failure using the building side battery 102 operating. . For example, the elevator system 1A described above may require a certain period of time after the power supply 50 for power failure to calculate the minimum operable time during a power failure. In this case, immediately after the power failure of the power source 50, the control device 10 once performs an operation without continuous restriction at the time of power failure using the elevator side battery 12, and the building side battery 102 after completing the calculation of the minimum operation time possible at the time of power failure. You may make it perform an unrestricted operation at the time of a power failure using. Thereby, the elevator system 1A can continue the service immediately after the power failure of the power source 50.

また、エレベータシステム１Ａは、上述の停電時制限有り運転、停電時継続制限有り運転の際に、車椅子利用者等の特定の利用者に対する停止禁止階へのサービスを許容することもできる。この場合、エレベータシステム１Ａは、例えば、カゴ２内や乗場６にＩＤカード等の識別情報を読み取ることができる読取装置を備える。そして、エレベータシステム１Ａは、車椅子利用者等が、自身の識別情報や目的階等が書き込まれたＩＤカードの識別情報を当該読取装置に読み取らせることで、目的階が停止禁止階であってもカゴ２の当該停止禁止階への停止を許容するようにする。これにより、エレベータシステム１Ａは、停電時制限有り運転や停電時継続制限有り運転の最中であっても、車椅子利用者等の特定の利用者に対するサービス性を適正に確保することができる。   Further, the elevator system 1A can allow a service to a stop prohibition floor for a specific user such as a wheelchair user during the above-described operation with restriction during a power failure and operation with continuation restriction during a power failure. In this case, the elevator system 1A includes, for example, a reading device that can read identification information such as an ID card in the car 2 or the hall 6. The elevator system 1A allows the wheelchair user or the like to read the identification information of the ID card on which the identification information or the destination floor is written by the reading device, so that even if the destination floor is a stop-prohibited floor The stop of the basket 2 to the stop prohibited floor is allowed. As a result, the elevator system 1A can appropriately ensure serviceability for a specific user such as a wheelchair user even during a limited operation during a power failure or a continuous operation during a power failure.

以上で説明したエレベータシステム１Ａは、エレベータ１と、制御装置１０とを備える。エレベータ１は、動力用電源５０からの電力と、建物１００の電気設備１０１を作動させる電力を蓄電可能である建物側バッテリ１０２からの電力とによって運転可能である。制御装置１０は、動力用電源５０の健全時にエレベータ１を定格速度で運転する通常運転と、動力用電源５０の停電時に建物側バッテリ１０２からの電力によってエレベータ１を定格速度で運転する停電時運転とを切り替えて実行可能である。制御装置１０は、停電時運転として、停電時制限無し運転と停電時制限有り運転とを切り替えて実行可能である。停電時制限無し運転は、動力用電源５０が停電した後、当該動力用電源５０の停電時の建物側バッテリ１０２の残存蓄電量に基づいた停電時運転可能最低時間経過前の期間に通常運転と同等の運転を行うものである。停電時制限有り運転は、停電時運転可能最低時間経過後でかつ建物側バッテリ１０２の残存蓄電量が運転可能蓄電量以上である場合に停電時制限無し運転と比較してエレベータ１の停止可能階床を制限して運転するものである。したがって、エレベータシステム１Ａは、動力用電源５０が停電した場合であっても、建物側バッテリ１０２の電力を用いて停電時の運転を適正に行うことができる。   The elevator system 1A described above includes the elevator 1 and the control device 10. The elevator 1 can be operated by electric power from the power source 50 for power and electric power from the building-side battery 102 that can store electric power for operating the electric equipment 101 of the building 100. The control device 10 operates in a normal operation in which the elevator 1 is operated at a rated speed when the power source 50 is healthy, and in a power failure operation in which the elevator 1 is operated at a rated speed by power from the building-side battery 102 when the power source 50 is out of power. Can be executed by switching between The control device 10 can execute the operation at the time of a power failure by switching between an operation without a power failure restriction and an operation with a power failure restriction. The unrestricted operation at the time of a power failure is a normal operation after a power failure of the power source 50 and during a period before the elapse of the minimum allowable operating time at the time of power failure based on the remaining power storage amount of the building-side battery 102 at the time of the power failure of the power source 50. The same operation is performed. The operation with a limit at the time of a power failure is a floor where the elevator 1 can be stopped in comparison with the operation without a limit at the time of a power failure when the remaining power storage capacity of the building-side battery 102 is equal to or greater than the driveable power storage amount after the minimum operating time at a power failure has elapsed. Driving with limited floor. Therefore, the elevator system 1 </ b> A can appropriately perform the operation at the time of the power failure using the power of the building-side battery 102 even when the power source 50 for power failure occurs.
