Description

エレベーター及びエレベーター制御装置Elevator and elevator control device
　本発明は、エレベーター及びエレベーター制御装置に関する。 The present invention relates to an elevator and an elevator control device.
　従来の乗りかごは、昇降路内の電源と、乗りかごとを結ぶテールコードを通じて電力供給を受け、乗りかご内の機器（かご内照明、空調機等）が動作されていた。しかし、乗りかごが長行程でサービスを提供するようになると、テールコードの重さが乗りかごの移動に影響を与える。このため、テールコードをなくしたエレベーター装置が提供されるようになった。このようなエレベーター装置では、乗りかごに設置したバッテリーから供給される電力により乗りかご内の機器が動作される。バッテリーの電力残量が少なくなると、昇降路内の給電階に乗りかごが停止して、給電階に設置された給電装置から非接触でバッテリーに充電されていた。このように給電装置が非接触でバッテリーに電力を給電する方法を「非接触給電」と呼ぶ。 In the conventional car, power is supplied through a power supply in the hoistway and a tail cord connecting the car and the devices in the car (car interior lighting, air conditioner, etc.) are operated. However, the weight of the tail cord affects the movement of the car when the car comes to provide service on a long journey. For this reason, the elevator apparatus which eliminated the tail cord came to be provided. In such an elevator apparatus, the equipment in the car is operated by the power supplied from the battery installed in the car. When the remaining power of the battery is low, the car stops at the feeding floor in the hoistway, and the battery is charged in a contactless manner from the feeding device installed at the feeding floor. The method in which the power supply apparatus supplies power to the battery contactlessly in this manner is called "contactless power supply".

　ところで、乗りかごに設置されたバッテリーの電力残量は、乗りかごの運行に従って減少する。しかし、乗りかごに設置されたバッテリーの電力容量は多くなく、バッテリーに給電する回数は頻繁となる。直ちに乗りかごを給電階まで移動できればバッテリーを充電可能であるが、混雑時間帯（例えば、出勤時、昼食時、退勤時）には乗りかごの利用頻度が高いため、乗りかごを給電階で停止し続けることが難しい。 By the way, the remaining power of the battery installed in the car decreases with the operation of the car. However, the power capacity of the battery installed in the car is not large, and the battery is frequently supplied with power. If you can move the car to the feeding floor immediately, you can charge the battery, but stop the car at the feeding floor because the usage frequency of the car is high during busy hours (for example, when working, lunching, working) It is difficult to keep doing.
　また、特許文献１には、複数の号機を群管理する制御システムについて開示されている。しかし、特許文献１に開示された技術では、複数の号機を備えるエレベーターでなければ、充電が必要なバッテリーが設置される乗りかごを給電階に移動させて給電を行うことができない。しかし、１機の乗りかごだけが設置されるエレベーターでは、例えば乗りかごに乗車する利用者の数が多い時間帯になると、乗りかごが頻繁に移動する。バッテリーの電力残量が減少しすぎると、例えば、照明部の照明が切れてしまうといった弊害が生じる。このような事態を避けるには、利用者の有無にかかわらず乗りかごを給電階に移動させてバッテリーを充電しなければならず、利用者に十分なサービスを提供することができなかった。 In addition, Patent Document 1 discloses a control system that group-controls a plurality of units. However, with the technology disclosed in Patent Document 1, it is not possible to perform power feeding by moving a car on which a battery that needs to be charged is installed to a power feeding floor unless using an elevator equipped with a plurality of units. However, in an elevator in which only one car is installed, the car moves frequently, for example, in a time zone in which the number of users who get on the car is large. If the remaining power of the battery is reduced too much, for example, the lighting unit may be turned off. In order to avoid such a situation, it is necessary to move the car to the power supply floor to charge the battery regardless of the presence or absence of the user, and it has not been possible to provide sufficient service to the user.
　本発明はこのような状況に鑑みて成されたものであり、乗りかごに搭載されたバッテリーへの給電と、利用者に提供可能なサービスとのバランスをとることを目的とする。 The present invention has been made in view of such a situation, and an object thereof is to balance power feeding to a battery mounted in a car with a service that can be provided to a user.
　本発明に係るエレベーターは、昇降路を移動する乗りかごと、乗りかごの運行を制御するエレベーター制御装置と、を備える。乗りかごは、乗りかごで使用される機器に供給される電力を蓄電する蓄電部と、昇降路の給電階に設置された給電部から給電される電力を受電し、蓄電部を充電する受電部と、を有する。
　エレベーター制御装置は、蓄電部に蓄電される電力の電力残量と、予め設定された判定値とを比較する比較部と、電力残量が判定値以下である場合に機器に供給する電力の電力量を減じる電力供給部と、を備える。 An elevator according to the present invention comprises an elevator control device for controlling the operation of a car and a car moving on a hoistway. The car receives an electric power supplied from a power storage unit for storing power supplied to devices used in the car and a power supply unit installed at a power supply floor of the hoistway, and a power receiving unit for charging the power storage unit And.
The elevator control device compares the remaining amount of power stored in the storage unit with a preset determination value, and the power of the power supplied to the device when the remaining amount of power is equal to or less than the determination value And a power supply that reduces the amount.
　本発明によれば、電力残量に応じて機器に供給する電力の電力量が減じられるため、給電回数を減らすことができ、例えば乗りかごに乗車する利用者の数が多い時間帯であっても利用者にサービスを継続して提供することが可能となる。
　上記した以外の課題、構成及び効果は、以下の実施の形態の説明により明らかにされる。 According to the present invention, since the amount of power supplied to the device can be reduced according to the remaining amount of power, the number of times of power feeding can be reduced, for example, a time zone in which the number of users who get on a car is large. It will also be possible to continue providing services to users.
Problems, configurations, and effects other than those described above will be apparent from the description of the embodiments below.

　昇降路５は、複数階床用であって、乗りかご１０は、行き先階に応じて各階の停止位置を示す着床レベル（乗場）で停止する。支持体６は、乗りかご１０を支持する昇降路５の壁、柱、又はガイドレール等である。コイルユニット８は、非接触給電の送電を担う給電部の一例として用いられ、支持体６に直接又は他の物体を介して間接的に固定される。このコイルユニット８は、利用者が多い１階又は最上階（展望階）等を給電階とする昇降路５の内部に設置される。図１では、コイルユニット８が１階に設置された例が示される。 The hoistway 5 is for multiple floors, and the car 10 is stopped at a landing level (hallhole) that indicates the stop position of each floor according to the destination floor.

The coil unit 21 a receives the power transmitted from the coil unit 8. The charging circuit 21b charges the battery 22 with the power received by the coil unit 21a.
　バッテリー２２は、乗りかご１０で使用される機器に供給される電力を蓄電する蓄電部の一例として用いられる。バッテリー２２として、例えば、キャパシタ、鉛蓄電池、リチウムイオン電池等が用いられる。 The battery 22 is used as an example of a power storage unit that stores power supplied to devices used in the car 10.

Represents power.
　エレベーター制御装置３は、比較部３１、電力供給部３２、判定値記憶部３３、判定値変更部３４及び運行制御部３５を備える。
　比較部３１は、バッテリー２２に蓄電される電力の電力残量（以下、「バッテリー残量」と呼ぶ）と、判定値記憶部３３に予め設定される第１判定値及び第２判定値とを比較し、比較結果を電力供給部３２に出力する。なお、第２判定値は、第１判定値より低い値である。 The elevator control device 3 includes a comparison unit 31, a power supply unit 32, a determination value storage unit 33, a determination value change unit 34, and an operation control unit 35.
Comparison unit 31 compares the remaining amount of power stored in battery 22 (hereinafter referred to as “remaining battery amount”), and the first determination value and the second determination value set in advance in determination value storage unit 33. The comparison is performed, and the comparison result is output to the power supply unit 32. The second determination value is a value lower than the first determination value.
　電力供給部３２は、比較部３１から入力された比較結果に基づいて、バッテリー２２が乗りかご１０で使用される機器に供給する電力の電力量を減じて、乗りかご１０で使用される機器に電力を供給する。乗りかご１０で使用される機器に供給する電力の電力量が減じられるのは、バッテリー残量が第１判定値以下、又は第１判定値及び第２判定値以下である場合となる。 The power supply unit 32 reduces the amount of power supplied by the battery 22 to the device used by the car 10 based on the comparison result input from the comparison unit 31, thereby reducing the power consumption by the device used by the car 10. Supply power. The amount of power supplied to the devices used in the car 10 is reduced when the battery remaining amount is less than or equal to the first determination value or less than or equal to the first determination value and the second determination value.
　判定値記憶部３３には、比較部３１により参照される判定値として、第１判定値及び第２判定値が記憶されている。第１判定値及び第２判定値は、電力供給部３２により判定値記憶部３３から適宜読み出され、バッテリー残量との比較に用いられる。 The determination value storage unit 33 stores a first determination value and a second determination value as the determination values referred to by the comparison unit 31. The first determination value and the second determination value are appropriately read from the determination value storage unit 33 by the power supply unit 32, and are used for comparison with the battery remaining amount.
　判定値変更部３４は、運行制御部３５から供給される乗りかご１０の運行状況、又は乗りかご１０の運行時刻が含まれる時間帯に応じて、判定値記憶部３３に設定される第１判定値及び第２判定値を増加又は減少する変更を行う。また、判定値変更部３４は、過去の所定期間（例えば、現在時刻から過去１時間）における電力残量の平均値が、現在の第１判定値以下である場合に、第１判定値及び第２判定値を増加する変更を行う。また、判定値変更部３４は、過去の所定期間（例えば、現在時刻から過去１時間）における電力残量の平均値が、現在の第１判定値を超える場合に、第１判定値及び第２判定値を減少する変更を行う。 The determination value changing unit 34 sets the first determination set in the determination value storage unit 33 according to the operation status of the car 10 supplied from the operation control unit 35 or the time zone in which the operation time of the car 10 is included. Change to increase or decrease the value and the second judgment value. In addition, when the average value of the remaining power during a predetermined period in the past (for example, one hour from the current time) is equal to or less than the current first determination value, the determination value changing unit 34 determines the first determination value and the 2 Make a change to increase the judgment value. In addition, when the average value of the remaining power during a predetermined period in the past (for example, one hour from the current time) exceeds the current first determination value, the determination value changing unit 34 determines the first determination value and the second determination value. Make a change that reduces the judgment value.
　運行制御部３５は、乗りかご１０で使用される機器の動作を制御し、各機器の動作状況を取得する。そして、運行制御部３５は、乗りかご１０の運行を制御し、乗りかご１０の運行状況を比較部３１に通知する。また、運行制御部３５は、バッテリー２２への充電状況をコイルユニット２１ａから受信する。また、運行制御部３５は、巻上機４の動作を制御して、巻上機４に主ロープを巻上げさせ、乗りかご１０を昇降路５内で移動させる。そして、運行制御部３５は、エンコーダー４ａから送られる情報を解析して、乗りかご１０の現在位置を確認する。 The operation control unit 35 controls the operation of the devices used in the car 10 and acquires the operation status of each device. Then, the operation control unit 35 controls the operation of the car 10 and notifies the comparison unit 31 of the operation status of the car 10. In addition, the operation control unit 35 receives the charging status of the battery 22 from the coil unit 21a. The operation control unit 35 also controls the operation of the hoisting machine 4 to cause the hoisting machine 4 to wind up the main rope and move the car 10 in the hoistway 5. Then, the operation control unit 35 analyzes the information sent from the encoder 4 a and confirms the current position of the car 10.
　そして、運行制御部３５は、乗りかご１０が給電階に到着した場合に、かごドア２７の開時間を、給電階以外の階床に停止した場合におけるかごドア２７の開時間よりも延長する。これにより、乗りかご１０が給電階に停止する時間が長くなり、受電部２１がコイルユニット８から送電される電力を受電する時間も長くなる。この結果、受電部２１がバッテリー２２に充電する時間が長くなり、バッテリー２２に十分な電力を充電することが可能となる。 Then, when the car 10 arrives at the power feeding floor, the operation control unit 35 extends the open time of the car door 27 more than the open time of the car door 27 when stopping on a floor other than the power feeding floor. As a result, the time when the car 10 stops at the feeding floor becomes longer, and the time when the power receiving unit 21 receives the power transmitted from the coil unit 8 also becomes longer. As a result, the time for which the power receiving unit 21 charges the battery 22 becomes long, and it becomes possible to charge the battery 22 with sufficient power.
　図３は、エレベーター制御装置３を構成する計算機Ｃのハードウェア構成例を示すブロック図である。
　計算機Ｃは、いわゆるコンピューターとして用いられるハードウェアである。計算機Ｃは、バスＣ４にそれぞれ接続されたＣＰＵ（Central Processing Unit：中央処理装置）Ｃ１、ＲＯＭ（Read Only Memory）Ｃ２、ＲＡＭ（Random Access Memory）Ｃ３を備える。さらに、計算機Ｃは、不揮発性ストレージＣ５、ネットワークインターフェイスＣ６を備える。 FIG. 3 is a block diagram showing an example of the hardware configuration of the computer C that constitutes the elevator control device 3. As shown in FIG.
The computer C is hardware that is used as a so-called computer. The computer C includes a central processing unit (CPU) C1 connected to the bus C4, a read only memory (ROM) C2, and a random access memory (RAM) C3. Furthermore, the computer C includes a non-volatile storage C5 and a network interface C6.
　ＣＰＵ Ｃ１は、本実施の形態例に係る各機能を実現するソフトウェアのプログラムコードをＲＯＭ Ｃ２から読み出して実行する。ＲＡＭ Ｃ３には、演算処理の途中に発生した変数やパラメーター等が一時的に書き込まれる。 The CPU C1 reads out from the ROM C2 a program code of software that implements each function according to the present embodiment and executes it. In the RAM C3, variables, parameters, and the like generated during the arithmetic processing are temporarily written.
　不揮発性ストレージＣ５としては、例えば、ＨＤＤ（Hard Disk Drive）、ＳＳＤ（Solid State Drive）、フレキシブルディスク、光ディスク、光磁気ディスク、ＣＤ－ＲＯＭ、ＣＤ－Ｒ、磁気テープ、不揮発性のメモリ等が用いられる。この不揮発性ストレージＣ５には、ＯＳ（Operating System）、各種のパラメーターの他に、エレベーター制御装置３を機能させるためのプログラムが記録されている。ＲＯＭ Ｃ２、不揮発性ストレージＣ５は、ＣＰＵ Ｃ１が動作するために必要なプログラムやデータ等を記録しており、エレベーター制御装置３によって実行されるプログラムを格納したコンピューター読取可能な非一過性の記録媒体の一例として用いられる。 As the non-volatile storage C5, for example, a hard disk drive (HDD), a solid state drive (SSD), a flexible disk, an optical disk, an optical magnetic disk, a CD-ROM, a CD-R, a magnetic tape, a non-volatile memory, etc. are used. Be In addition to OS (Operating System) and various parameters, a program for causing the elevator control device 3 to function is recorded in the non-volatile storage C5. The ROM C2 and the non-volatile storage C5 store programs, data, etc. necessary for the CPU C1 to operate, and are computer readable non-transitory records storing programs executed by the elevator control device 3 It is used as an example of a medium.
　ネットワークインターフェイスＣ６には、例えば、ＮＩＣ（Network Interface Card）等が用いられ、端子が接続されたＬＡＮ（Local Area Network）、専用線等を介して各種のデータを装置間で送受信することが可能である。 For example, a NIC (Network Interface Card) or the like is used for the network interface C6, and various data can be transmitted and received between devices via a LAN (Local Area Network) to which a terminal is connected, a dedicated line, or the like. is there.
　図４は、バッテリー２２の蓄電容量と、現在のバッテリー残量との例を示す説明図である。例えば、バッテリー２２の蓄電容量を１００％とすると、図１に示した受電部２１は、バッテリー２２に対して最大で１００％まで充電することが可能である。 FIG. 4 is an explanatory view showing an example of the storage capacity of the battery 22 and the current remaining amount of the battery. For example, assuming that the storage capacity of the battery 22 is 100%, the power receiving unit 21 shown in FIG. 1 can charge the battery 22 up to 100%.
　図４では、バッテリー残量を斜線で塗りつぶして表す。例えば、現在のバッテリー残量は、蓄電容量の８０％とする。また、蓄電容量の５０％を第１判定値とし、蓄電容量の３０％を第２判定値とする。バッテリー残量が蓄電容量の８０％であれば、バッテリー残量は十分にあるため、乗りかご１０で使用される機器には通常使用される電力が電力供給部３２から供給される。 In FIG. 4, the remaining battery amount is indicated by hatching. For example, the current remaining amount of battery is 80% of the storage capacity. Further, 50% of the storage capacity is taken as a first determination value, and 30% of the storage capacity is taken as a second determination value. If the remaining battery capacity is 80% of the storage capacity, the remaining battery capacity is sufficient, so that the power used by the equipment used in the car 10 is supplied from the power supply unit 32.
　しかし、バッテリー残量が蓄電容量の５０％以下になると、電力供給部３２により、照明部２４及び表示部２６に供給される電力の電力量が減じられる。このため、照明部２４は、通常使用される輝度よりも低い輝度で乗りかご１０内を照明する。また、表示部２６は、通常使用される輝度よりも低い輝度で行先階等の案内を表示する。このように照明部２４及び表示部２６に供給される電力の電力量が減じられたとしても、乗りかご１０に乗車する利用者にとって快適性が著しく低下することはない。 However, when the battery remaining amount becomes 50% or less of the storage capacity, the power supply unit 32 reduces the amount of power supplied to the illumination unit 24 and the display unit 26. For this reason, the illumination unit 24 illuminates the interior of the car 10 at a lower luminance than that normally used. In addition, the display unit 26 displays the guidance such as the destination floor at a lower luminance than that normally used. Thus, even if the amount of power supplied to the illumination unit 24 and the display unit 26 is reduced, the comfort for the user riding on the car 10 is not significantly reduced.
　さらに、バッテリー残量が蓄電容量の３０％以下になると、電力供給部３２により、空調部２５に供給される電力の電力量が減じられる。このとき、空調部２５のファンが停止する。このように空調部２５に供給される電力の電力量が減じられたとしても、乗りかご１０に乗車する利用者にとって快適性が著しく低下することはない。 Furthermore, when the battery remaining amount becomes 30% or less of the storage capacity, the power supply unit 32 reduces the amount of power supplied to the air conditioning unit 25. At this time, the fan of the air conditioning unit 25 is stopped. Thus, even if the amount of power supplied to the air conditioning unit 25 is reduced, the comfort for the user in the car 10 is not significantly reduced.
　上述したように第１判定値及び第２判定値は、乗りかご１０が運行される時間帯、乗りかご１０が設置される建物における運行状況等に応じて、判定値変更部３４により変更される。例えば、乗りかご１０が運行される時間帯が通常利用される時間帯であれば、第１判定値及び第２判定値は初期値（第１判定値が５０％、第２判定値が３０％）が維持される。しかし、利用者があまり乗車しない深夜帯等であれば、判定値変更部３４により、第１判定値及び第２判定値は初期値よりも低い値に変更される。このため、バッテリー残量が第１判定値及び第２判定値よりも低くなりにくく、乗りかご１０が給電階に移動する回数を減らすことができる。 As described above, the first determination value and the second determination value are changed by the determination value changing unit 34 according to the time zone in which the car 10 is operated, the operation status in the building in which the car 10 is installed, and the like. . For example, if the time zone in which the car 10 is operated is a time zone normally used, the first determination value and the second determination value are initial values (the first determination value is 50%, and the second determination value is 30%). ) Is maintained. However, in the case of a late night zone or the like where the user hardly rides, the determination value changing unit 34 changes the first determination value and the second determination value to values lower than the initial value. Therefore, the battery remaining amount is less likely to be lower than the first determination value and the second determination value, and the number of times the car 10 moves to the power feeding floor can be reduced.
　一方、乗りかご１０が運行される時間帯が、混雑時間帯であれば、乗りかご１０が給電階にて停止する時間が短くなるため、バッテリー残量が減少しやすい。そこで、判定値変更部３４により、第１判定値及び第２判定値は初期値よりも高い値に変更される。このため、バッテリー残量が、変更された第１判定値及び第２判定値よりも低くなると、直ちに乗りかご１０で使用される機器に供給される電力の電力量が減少する。これにより、混雑時間帯であっても、乗りかご１０が給電階に移動する回数を減らすことができる。 On the other hand, if the time zone in which the car 10 is operated is the congested time zone, the time for which the car 10 stops at the power feeding floor becomes short, so the remaining battery capacity tends to decrease. Therefore, the determination value changing unit 34 changes the first determination value and the second determination value to values higher than the initial value. For this reason, when the battery remaining amount becomes lower than the changed first determination value and the second determination value, the amount of power supplied to the device used in the car 10 immediately decreases. Thereby, even in the congested time zone, it is possible to reduce the number of times the car 10 moves to the feeding floor.

　図５は、乗りかご１０で使用される機器に供給される電力の電力量を制御する処理の例を示すフローチャートである。 <Example of elevator control processing>
Next, a processing example of the elevator control device 3 will be described with reference to FIG. 5 to FIG.
FIG. 5 is a flowchart showing an example of a process of controlling the amount of power supplied to the devices used in the car 10.
　始めに、比較部３１は、バッテリー残量が蓄電容量の５０％以下であるか否かを判定する（Ｓ１）。バッテリー残量が蓄電容量の５０％以下でないと判定された場合（Ｓ１のＮＯ）、バッテリー残量は十分にあるため、本処理を終了する。 First, the comparison unit 31 determines whether the remaining battery capacity is 50% or less of the storage capacity (S1). If it is determined that the battery remaining amount is not 50% or less of the storage capacity (NO in S1), the battery remaining amount is sufficient, and the present process is ended.
　バッテリー残量が蓄電容量の５０％以下であると判定された場合（Ｓ１のＹＥＳ）、電力供給部３２は、照明部２４及び表示部２６に供給する電力を減じる。このとき、例えば、照明部２４のＬＥＤ、及び表示部２６の液晶画面の輝度が下げられる（Ｓ２）。 When it is determined that the battery remaining amount is 50% or less of the storage capacity (YES in S1), the power supply unit 32 reduces the power supplied to the illumination unit 24 and the display unit 26. At this time, for example, the brightness of the LED of the illumination unit 24 and the liquid crystal screen of the display unit 26 is lowered (S2).
　次に、比較部３１は、バッテリー残量が蓄電容量の３０％以下であるか否かを判定する（Ｓ３）。バッテリー残量が蓄電容量の３０％以下でないと判定された場合（Ｓ３のＮＯ）、照明部２４のＬＥＤ、及び表示部２６の液晶画面の輝度を下げた状態で本処理を終了する。 Next, the comparison unit 31 determines whether the remaining battery capacity is 30% or less of the storage capacity (S3). When it is determined that the battery remaining amount is not 30% or less of the storage capacity (NO in S3), the processing is ended in a state where the brightness of the LED of the illumination unit 24 and the liquid crystal screen of the display unit 26 is lowered.
　バッテリー残量が蓄電容量の３０％以下であると判定された場合（Ｓ３のＹＥＳ）、電力供給部３２は、空調部２５に供給する電力を減じる。これにより、空調部２５のファンが停止する（Ｓ４）。 If it is determined that the battery remaining amount is equal to or less than 30% of the storage capacity (YES in S3), the power supply unit 32 reduces the power supplied to the air conditioning unit 25. Thereby, the fan of the air-conditioning unit 25 is stopped (S4).
　次に、運行制御部３５は、乗りかご１０が給電階に停止したか否かを判定し（Ｓ５）、比較部３１によるバッテリー残量の比較結果を受信する。ステップＳ３を経たことにより、運行制御部３５は、比較部３１より、バッテリー残量が蓄電容量の３０％以下であると判定されたことを示す比較結果を受信している。 Next, the operation control unit 35 determines whether or not the car 10 has stopped at the power feeding floor (S5), and receives the comparison result of the battery remaining amount by the comparison unit 31. After passing through step S3, the operation control unit 35 receives, from the comparison unit 31, a comparison result indicating that the battery remaining amount is determined to be 30% or less of the storage capacity.
　そして、運行制御部３５は、乗りかご１０が給電階に停止していないと判定した場合（Ｓ５のＮＯ）、本処理を終了する。一方、乗りかご１０が給電階に停止したと判定した場合（Ｓ５のＹＥＳ）、運行制御部３５は、乗りかご１０が給電階でかごドア２７を開く時間を、乗りかご１０が給電階以外に停止したときにかごドア２７を開く時間よりも延長する（Ｓ６）これにより、バッテリー２２への充電時間を長く確保することができる。その後、本処理を終了する。 Then, when it is determined that the car 10 has not stopped at the power feeding floor (NO in S5), the operation control unit 35 ends the present process. On the other hand, when it is determined that the car 10 has stopped at the power feeding floor (YES in S5), the operation control unit 35 sets the time for the car 10 to open the car door 27 at the power feeding floor. The time for charging the battery 22 can be secured longer than the time for opening the car door 27 when stopped (S6). Thereafter, the process ends.
＜現在の判定値を変更する第１の処理の例＞
　エレベーター１の運行状況は時間毎に変化するものであり、第１判定値及び第２判定値を固定したままではバッテリー残量がすぐに第１判定値及び第２判定値よりも低下する場合がある。しかし、バッテリー２２への充電回数をなるべく抑える必要がある。そこで、電力供給部３２は、第１判定値及び第２判定値を変更する第１の処理を行う。以下に電力供給部３２が第１判定値及び第２判定値を変更する第１の処理の例について、図６と図７を参照して説明する。 <Example of First Processing to Change Current Determination Value>
The operation status of the elevator 1 changes with time, and when the first determination value and the second determination value are fixed, there may be a case where the battery remaining amount immediately drops below the first determination value and the second determination value. is there. However, it is necessary to minimize the number of times the battery 22 is charged. Therefore, the power supply unit 32 performs a first process of changing the first determination value and the second determination value. An example of the first process in which the power supply unit 32 changes the first determination value and the second determination value will be described below with reference to FIGS. 6 and 7.
　図６は、判定値変更部３４が第１判定値及び第２判定値を変更する第１の処理の例を示すフローチャートである。
　図７は、過去１時間のバッテリー残量の平均値と、変更された第１判定値及び第２判定値の例を示す説明図である。 FIG. 6 is a flowchart showing an example of a first process in which the determination value changing unit 34 changes the first determination value and the second determination value.
FIG. 7 is an explanatory view showing an example of the average value of the battery remaining amount in the past one hour, and the changed first determination value and second determination value.
　始めに、判定値変更部３４は、運行制御部３５から供給される運行データに基づいて、現時刻が混雑時間帯（出勤時、昼食時、退勤時）であるか否かを判定する（Ｓ１１）。現時刻が混雑時間帯であると判定された場合（Ｓ１１のＹＥＳ）、判定値変更部３４は、第１判定値を５０％から７０％に変更し、第２判定値を３０％から５０％に変更して（Ｓ１２）、本処理を終了する。混雑時間帯では、バッテリー残量が減少しやすいので、少しでもバッテリー残量の減少を抑えるために、乗りかご１０で使用される機器に供給される電力の電力量を減少する制御が早めに行われる。 First, based on the operation data supplied from the operation control unit 35, the determination value changing unit 34 determines whether or not the current time is a congested time zone (at work, at lunch, at work) (S11). ). When it is determined that the current time is in the congestion time zone (YES in S11), the determination value changing unit 34 changes the first determination value from 50% to 70%, and the second determination value from 30% to 50%. To (S12), and the process ends. In the congested time zone, since the remaining battery capacity tends to decrease, the control for reducing the amount of power supplied to the devices used in the car 10 is performed earlier to suppress the decrease in the remaining battery capacity. It will be.
　ステップＳ１１にて現時刻が混雑時間帯でないと判定された場合（Ｓ１１のＮＯ）、判定値変更部３４は、現在時刻から過去１時間のバッテリー残量の平均値（「平均バッテリー残量」と呼ぶ）が、現在の判定値（例えば、第１判定値）以下であるか否かを判定する（Ｓ１３）。なお、ステップＳ１３の判定に用いられる現在の判定値は、第２判定値としてもよい。 When it is determined in step S11 that the current time is not in the congested time zone (NO in S11), the determination value changing unit 34 determines the average value of the remaining battery capacity for the past 1 hour from the current time (“average battery remaining amount”). It is determined whether or not the call is less than or equal to the current determination value (for example, the first determination value) (S13). The current determination value used for the determination of step S13 may be the second determination value.
　図７Ａには、平均バッテリー残量が、現在の判定値である５０％以下であることが示される。そして、図７Ａでは、現在の判定値を「現第１判定値」と記載する。平均バッテリー残量が現在の判定値以下であると判定された場合（Ｓ１３のＹＥＳ）、判定値変更部３４は、現在の判定値に１０％を加えて（Ｓ１４）、本処理を終了する。これにより、第１判定値が５０％から６０％に変更される。なお、第１判定値の変更に合わせて第２判定値に１０％を加え、第２判定値を３０％から４０％に変更してもよい。図７Ａでは、変更された第１判定値を「新第１判定値」と記載し、変更された第２判定値を「新第２判定値」と記載する。このように現在の判定値が上げられるため、現時刻が混雑時間帯でなくても、バッテリー残量が減少しやすい運行状況であれば、乗りかご１０で使用される機器に供給される電力が減少するため、バッテリー残量の減少を抑えることができる。 FIG. 7A shows that the average battery remaining amount is 50% or less, which is the current determination value. And in FIG. 7A, the present determination value is described as "the present 1st determination value." If it is determined that the average battery remaining amount is equal to or less than the current determination value (YES in S13), the determination value changing unit 34 adds 10% to the current determination value (S14), and ends this processing. Thereby, the first determination value is changed from 50% to 60%. The second determination value may be changed from 30% to 40% by adding 10% to the second determination value in accordance with the change of the first determination value. In FIG. 7A, the changed first determination value is described as “new first determination value”, and the changed second determination value is described as “new second determination value”. Since the current determination value can be increased as described above, the power supplied to the devices used in the car 10 can be reduced if the battery remaining amount is likely to decrease even if the current time is not in the congested time zone. The decrease in the remaining battery capacity can be suppressed.
　平均バッテリー残量が現在の判定値を超えると判定された場合（Ｓ１３のＮＯ）、判定値変更部３４は、現在の判定値から１０％を減じて（Ｓ１５）、本処理を終了する。図７Ｂには、平均バッテリー残量が、現在の判定値である５０％を超えることが示される。これにより、第１判定値が５０％から４０％に変更される。なお、第１判定値の変更に合わせて第２判定値に１０％を減じ、第２判定値を３０％から２０％に変更してもよい。このように現時刻が混雑時間帯でなく、バッテリー残量が減少しにくい運行状況であれば、現在の判定値が下げられることで、乗りかご１０で使用される機器に供給する電力を減少することなく、長い間、機器を通常使用される状態で維持することができる。 If it is determined that the average battery remaining amount exceeds the current determination value (NO in S13), the determination value changing unit 34 subtracts 10% from the current determination value (S15), and ends the present process. FIG. 7B shows that the average battery remaining amount exceeds 50%, which is the current determination value. Thereby, the first determination value is changed from 50% to 40%. The second determination value may be reduced from 30% to 20% by subtracting 10% from the second determination value in accordance with the change of the first determination value. As described above, if the current time is not the congested time zone and the operation state in which the battery remaining amount is hard to decrease, the current determination value is lowered to reduce the power supplied to the devices used in the car 10 Instead, the device can be maintained in normal use for a long time.
＜現在の判定値を変更する第２の処理の例＞
　次に、現在の判定値を変更する第２の処理の例について説明する。上述した図１では、給電階を１階だけに設けた例を示したが、給電階は他の階にも設けることができる。給電階が多くなるほど、乗りかご１０が停止したときにバッテリー２２に充電する階数、充電時間が長くなるが、給電階の設置コストも上昇する。このため、建物により、給電階が設置される階数は異なる。そこで、エレベーター１の設置時に、全階床に対する給電階の設置階数に応じた判定値の変更が行われる。 <Example of Second Processing to Change Current Determination Value>
Next, an example of a second process of changing the current determination value will be described. Although FIG. 1 described above shows an example in which the feeding floor is provided only on the first floor, the feeding floor can be provided on other floors. As the number of power feeding floors increases, the number of floors charging the battery 22 when the car 10 stops and the charging time become longer, but the cost of installing the power feeding floors also increases. For this reason, the number of floors on which the feed floor is installed varies depending on the building. Therefore, when the elevator 1 is installed, the determination value is changed according to the number of installation floors of the power supply floor with respect to all floors.
　図８は、判定値変更部３４が第１判定値及び第２判定値を変更する第２の処理の例を示すフローチャートである。第１判定値及び第２判定値の初期値は、それぞれ５０％、３０％とする。 FIG. 8 is a flowchart illustrating an example of a second process in which the determination value changing unit 34 changes the first determination value and the second determination value. Initial values of the first determination value and the second determination value are 50% and 30%, respectively.
　始めに、判定値変更部３４は、全階床に対し、給電階の割合が高いか否かを判定する（Ｓ２１）。例えば、５階床毎に給電階が１つ設けられるのであれば、１０階床あれば給電階が２つ設けられる。この場合、給電階の割合を２０％と計算する。そして、判定値変更部３４は、給電階の割合が２０％であることを判定値を変更する際の基準値とする。そして、判定値変更部３４は、給電階の割合が２０％以上であれば、第１判定値及び第２判定値を維持し、給電階の割合が２０％未満であれば、第１判定値及び第２判定値を減じる変更を行う。 First, the determination value changing unit 34 determines whether the ratio of the power supply floor is high with respect to all floors (S21). For example, if one feeding floor is provided for every 5 floors, if there are 10 floors, two feeding floors are provided. In this case, the proportion of the feed floor is calculated to be 20%. Then, the determination value changing unit 34 sets that the ratio of the power feeding floor is 20% as a reference value when changing the determination value. Then, the determination value changing unit 34 maintains the first determination value and the second determination value if the ratio of the power supply floor is 20% or more, and the first determination value if the ratio of the power supply floor is less than 20%. And change the second judgment value.
　例えば、１０階床の建物に３つの給電階が設けられると、給電階の割合が３３％である。このため、判定値変更部３４は、給電階の割合が２０％以上であり、給電階の割合が高いと判定する（Ｓ２１のＹＥＳ）。この場合、判定値変更部３４は、予め判定値記憶部３３に記憶されている現在の判定値を初期値のまま維持し（Ｓ２２）、本処理を終了する。このため、第１判定値が５０％、第２判定値が３０％のまま維持される。 For example, if a building with 10 floors is provided with 3 feed floors, the percentage of feed floors is 33%. For this reason, the determination value changing unit 34 determines that the ratio of the power feeding floor is 20% or more and the ratio of the power feeding floor is high (YES in S21). In this case, the determination value changing unit 34 maintains the current determination value stored in advance in the determination value storage unit 33 as the initial value (S22), and ends this processing. Therefore, the first determination value is maintained at 50% and the second determination value is maintained at 30%.
　例えば、１０階床の建物に１つの給電階が設けられると、給電階の割合が１０％である。このため、判定値変更部３４は、給電階の割合が２０％未満であり、給電階の割合が低いと判定する（Ｓ２１のＮＯ）。この場合、判定値変更部３４は、予め判定値記憶部３３に記憶されている現在の第１判定値及び第２判定値からそれぞれ５％減じ（Ｓ２３）、本処理を終了する。このとき、第１判定値が４５％、第２判定値が２５％に変更される。そして、変更された第１判定値及び第２判定値が初期値として判定値記憶部３３に記憶される。 For example, if one feed floor is provided in a 10-floor building, the percentage of feed floors is 10%. For this reason, the determination value changing unit 34 determines that the ratio of the power feeding floor is less than 20% and the ratio of the power feeding floor is low (NO in S21). In this case, the determination value changing unit 34 subtracts 5% from the current first determination value and second determination value stored in advance in the determination value storage unit 33 (S23), and ends this processing. At this time, the first determination value is changed to 45%, and the second determination value is changed to 25%. Then, the changed first determination value and second determination value are stored in the determination value storage unit 33 as initial values.
　以上説明した実施の形態に係るエレベーター１では、比較部３１が現在のバッテリー残量と判定値とを比較した結果に基づいて、電力供給部３２が、乗りかご１０で使用される機器に供給する電力の電力量を減じる。ここで、バッテリー２２の残量の判定値を段階的に設け、各々の判定値に応じて機器に供給する電力の電力量を変えることができる。例えば、現在のバッテリー残量が第１判定値以下となった場合に、照明部２４及び表示部２６に供給される電力の電力量が減少され、現在のバッテリー残量が第２判定値以下となった場合に、空調部２５に供給される電力の電力量が減少される。このため、バッテリー２２に充電するまでの間、バッテリー残量の減少を抑えることができる。また、現在のバッテリー残量が減少しても、乗りかご１０に乗車した利用者に対して不便を感じさせない。 In the elevator 1 according to the embodiment described above, the power supply unit 32 supplies the equipment used in the car 10 with the power supply unit 32 based on the result of the comparison unit 31 comparing the current battery remaining amount with the determination value. Reduce the amount of power. Here, determination values of the remaining amount of the battery 22 can be provided in stages, and the amount of power supplied to the device can be changed according to each determination value. For example, when the current battery remaining amount becomes equal to or less than the first determination value, the amount of electric power supplied to the lighting unit 24 and the display unit 26 is decreased, and the current battery remaining amount is equal to or less than the second determination value. If it does, the amount of power supplied to the air conditioning unit 25 is reduced. Therefore, it is possible to suppress a decrease in the remaining battery charge until the battery 22 is charged. In addition, even if the current remaining battery capacity decreases, it does not cause inconvenience for the user who gets on the car 10.
　また、判定値変更部３４は、エレベーター１の運行状況に応じて第１判定値及び第２判定値を変更することが可能である。例えば、判定値変更部３４は、エレベーター１の使用頻度が高い混雑時間帯であれば第１判定値及び第２判定値を増加し、使用頻度が低い時間帯であれば第１判定値及び第２判定値を減少する変更が可能である。このように判定値変更部３４は、エレベーター１の運行状況を学習することで、学習結果に応じて第１判定値及び第２判定値を適宜変更する運用が可能となる。そして、第１判定値及び第２判定値が適切な値に変更されるため、電力供給部３２が、乗りかご１０で使用される機器に供給する電力の電力量を減じるタイミングを遅らせることができる。 Further, the determination value changing unit 34 can change the first determination value and the second determination value in accordance with the operation status of the elevator 1. For example, the determination value changing unit 34 increases the first determination value and the second determination value if the frequency of use of the elevator 1 is high, and increases the first determination value and the second value if the frequency of use is low. 2 A change that decreases the judgment value is possible. Thus, by learning the operation status of the elevator 1, the determination value changing unit 34 can appropriately change the first determination value and the second determination value according to the learning result. Then, since the first determination value and the second determination value are changed to appropriate values, it is possible to delay the timing at which the power supply unit 32 reduces the amount of power supplied to the device used in the car 10 .
　また、判定値変更部３４は、全階床における給電階の割合に応じて予め設定されていた第１判定値及び第２判定値を変更することも可能である。このため、給電階の設置状況が異なる建物に応じて適切な第１判定値及び第２判定値を判定値記憶部３３に記憶させることができる。 Further, the determination value changing unit 34 can also change the first determination value and the second determination value which are set in advance according to the ratio of the power supply floor in all the floors. Therefore, the first determination value and the second determination value can be stored in the determination value storage unit 33 according to the buildings having different installation states of the feeding floor.
［変形例］
　なお、判定値変更部３４が変更する判定値は、第１判定値又は第２判定値のいずれか一つだけでもよい。 [Modification]
The determination value to be changed by the determination value changing unit 34 may be only one of the first determination value and the second determination value.
　また、例えば、バッテリー残量が蓄電容量の９０％以上まで充電されると、電力供給部３２は、乗りかご１０で使用される機器に供給される電力の電力量を元に戻してもよい。このため、照明部２４及び表示部２６の輝度が回復し、空調部２５のファンも回転を開始する。そして、バッテリー２２が満充電、又は、バッテリー残量が蓄電容量の９０％以上まで充電されるまでは、乗りかご１０で使用される機器に供給する電力の電力量が減少したままとなる。このため、バッテリー残量の減少を抑えることができる。 Also, for example, when the battery remaining amount is charged to 90% or more of the storage capacity, the power supply unit 32 may restore the amount of power of the power supplied to the device used in the car 10. Therefore, the brightness of the lighting unit 24 and the display unit 26 is recovered, and the fan of the air conditioning unit 25 also starts to rotate. Then, until the battery 22 is fully charged or the remaining battery charge is charged to 90% or more of the storage capacity, the amount of power supplied to the devices used in the car 10 remains reduced. For this reason, it is possible to suppress a decrease in the remaining battery capacity.
　また、エレベーター制御装置３は、乗りかご１０に設けられてもよい。そして、エレベーター制御装置３自身がバッテリー２２から電力の供給を受けて動作するようにしてもよい。 Further, the elevator control device 3 may be provided in the car 10. Then, the elevator control device 3 itself may be supplied with power from the battery 22 to operate.
　また、判定値記憶部３３に記憶される判定値として、第１判定値及び第２判定値がある。しかし、判定値は少なくとも１つあればよい。また、３つ以上の判定値が設けられてもよい。そして、電力供給部３２は、判定値毎に細かく分けた乗りかご１０で使用される機器に対して供給する電力の電力量を個別に変更してもよい。 Further, as the determination values stored in the determination value storage unit 33, there are a first determination value and a second determination value. However, at least one determination value is sufficient. In addition, three or more determination values may be provided. Then, the power supply unit 32 may individually change the amount of power supplied to devices used in the car 10 finely divided for each determination value.
