Abstract

A wireless remote monitoring system (100) for remotely monitoring a first elevator (11) via an LTE line network (30) includes: an elevator monitoring device (12); an LTE terminal (13) that is constantly connected to an APN1 of the LTE line network (30); and a first monitoring center (41) that is connected to the APN 1 and performs data exchange with the elevator monitoring device (12). When a connection to the first monitoring center (41) cannot be established, the elevator monitoring device (12) switches the constant connection destination of the LTE terminal (13) from the APN1 to an APN2 to which a second monitoring center (42) is connected, and performs data exchange with the second monitoring center (42). Thus, when an abnormality occurs in an LTE line, the remote monitoring can be backed up in a simple way.

Description

無線遠隔監視システムWireless remote monitoring system
　本発明は、ＬＴＥ回線網を用いたエレベーターの無線遠隔監視システムの構造に関する。 The present invention relates to a structure of an elevator wireless remote monitoring system using an LTE network.
　エレベーターの遠隔監視システムは、無線通信によってエレベーター監視装置と監視センターとの間のデータ授受を行うものが用いられている。無線通信回線としてはＬＴＥ回線と３Ｇ回線とを併用して用い、電波強度或いは基地局障害等により、ＬＴＥ回線の接続が確立できない場合にはＬＴＥ回線を３Ｇ回線に切換えてデータの授受を行う方法が提案されている（例えば、特許文献１，２参照）。 The remote monitoring system for elevators is used to exchange data between the elevator monitoring device and the monitoring center by wireless communication. A method in which an LTE line and a 3G line are used in combination as a wireless communication line, and when the connection of the LTE line cannot be established due to radio field strength or a base station failure, the LTE line is switched to a 3G line to exchange data. Has been proposed (see, for example, Patent Documents 1 and 2).

　ところで、ＬＴＥ回線網を通じて監視センターとエレベーター監視装置との間の通信を行う場合、エレベーター監視装置側のＬＴＥ端末は１つのアクセスポイントに常時接続されるので、ＬＴＥ端末と１つのアクセスポイントとの間で接続障害が発生すると、ＬＴＥ端末と監視センターとの間の通信を行うことができなくなってしまい、エレベーターの遠隔監視を行うことができなくなってしまう。 By the way, when communication is performed between the monitoring center and the elevator monitoring device through the LTE network, the LTE terminal on the elevator monitoring device side is always connected to one access point, and therefore, between the LTE terminal and one access point. If a connection failure occurs, communication between the LTE terminal and the monitoring center cannot be performed, and remote monitoring of the elevator cannot be performed.
　この場合、複数のアクセスポイントを用いてＬＴＥ端末と監視センターとの通信のバックアップを行うことが考えられる。しかし、ＬＴＥ端末は、常時接続しているアクセスポイント以外のアクセスポイントからの信号を受信できないので、他のアクセスポイントを用いて通信のバックアップを行うことが難しかった。 In this case, it is conceivable to back up communication between the LTE terminal and the monitoring center using a plurality of access points. However, since the LTE terminal cannot receive a signal from an access point other than the access point that is always connected, it is difficult to backup communication using another access point.
　また、エレベーター監視装置に複数のＬＴＥ端末を接続し、監視センターとの間の通信回線を二重化して通信のバックアップを行うことが考えられるが、システムが複雑になってしまうという問題があった。 In addition, it is conceivable to connect a plurality of LTE terminals to the elevator monitoring device and duplicate the communication line with the monitoring center to perform communication backup, but there is a problem that the system becomes complicated.
　そこで、本発明は、ＬＴＥ回線網を用いた遠隔監視システムにおいて、ＬＴＥ回線に異常が発生した場合に、簡便な方法で遠隔監視のバックアップを行うことを目的とする。 Therefore, an object of the present invention is to perform remote monitoring backup by a simple method when an abnormality occurs in the LTE line in the remote monitoring system using the LTE line network.
　本発明の無線遠隔監視システムは、エレベーターに接続されて前記エレベーターの運行状態を監視するエレベーター監視装置と、前記エレベーター監視装置に接続され、ＬＴＥ回線網の中の１のアクセスポイントに常時接続されるＬＴＥ端末と、前記ＬＴＥ回線網の前記１のアクセスポイントに接続されて前記エレベーター監視装置との間でデータの授受を行う１の監視センターと、を含み、前記ＬＴＥ回線網を介して前記エレベーターの遠隔監視を行う無線遠隔監視システムであって、前記エレベーター監視装置は、前記１の監視センターとの間の接続が確立できない場合に、前記ＬＴＥ端末の常時接続先を前記１のアクセスポイントから他の監視センターが接続されている他のアクセスポイントに切換えて、前記他の監視センターとの間でデータの授受を行うこと、を特徴とする。 The wireless remote monitoring system of the present invention is connected to an elevator and monitors the operation state of the elevator, is connected to the elevator monitoring device, and is always connected to one access point in the LTE network. An LTE terminal and one monitoring center connected to the one access point of the LTE line network and transferring data to and from the elevator monitoring device, and the elevator terminal via the LTE line network A wireless remote monitoring system that performs remote monitoring, wherein the elevator monitoring device determines whether to always connect the LTE terminal from the one access point to another when the connection with the one monitoring center cannot be established. Switch to another access point to which the monitoring center is connected, and connect to the other monitoring center. In that for exchanging data, characterized by.
　これにより、ＬＴＥ端末と常時接続先のアクセスポイントとの間の接続障害の発生によりエレベーター監視装置と１の監視センターとの間のデータ授受ができない場合でも、常時接続先のアクセスポイントを切換えることにより、エレベーター監視装置と他の監視センターとの間でデータ授受が可能となり、他の監視センターによりエレベーターの遠隔監視をバックアップすることができる。 As a result, even when data cannot be exchanged between the elevator monitoring apparatus and one monitoring center due to the occurrence of a connection failure between the LTE terminal and the always-connected access point, by switching the always-connected access point Data can be exchanged between the elevator monitoring device and another monitoring center, and remote monitoring of the elevator can be backed up by the other monitoring center.
　本発明の無線遠隔遠視システムにおいて、前記エレベーター監視装置は、前記ＬＴＥ端末の常時接続先を前記他のアクセスポイントに切換えた場合には、前記他のアクセスポイントとの常時接続を所定期間だけ保持すること、としてもよい。 In the wireless remote hyperopia system of the present invention, the elevator monitoring device maintains a constant connection with the other access point for a predetermined period when the constant connection destination of the LTE terminal is switched to the other access point. That's good.
　常時接続先のアクセスポイントを切換えたら所定期間その状態を保持することにより、他の監視センターからエレベーター監視装置へのアクセスを確保し、遠隔監視のバックアップ状態が解除されることを抑制できる。 If the access point of the connection destination is always switched, the state is maintained for a predetermined period, so that access to the elevator monitoring device from another monitoring center can be secured and the remote monitoring backup state can be prevented from being released.
　本発明の無線遠隔遠視システムにおいて、前記エレベーター監視装置は、前記ＬＴＥ端末の常時接続先を前記他のアクセスポイントに切換えた後、所定のインターバルで前記ＬＴＥ端末と前記１のアクセスポイントとの間の接続状態を確認し、前記１のアクセスポイントとの間の接続が確立できた場合には、前記ＬＴＥ端末の常時接続先を前記１のアクセスポイントに戻すこと、としてもよい。 In the wireless remote hyperopia system of the present invention, the elevator monitoring device switches between the LTE terminal and the one access point at a predetermined interval after switching the constant connection destination of the LTE terminal to the other access point. The connection state is confirmed, and when the connection with the one access point is established, the permanent connection destination of the LTE terminal may be returned to the one access point.
　このように、通常の監視センターからの遠隔監視に戻すことにより、他の監視センターの遠隔監視の負荷を通常状態に下げることができる。 Thus, by returning to the remote monitoring from the normal monitoring center, the remote monitoring load of other monitoring centers can be reduced to the normal state.
　本発明の無線遠隔監視システムにおいて、前記エレベーター監視装置は、前記ＬＴＥ端末が所定回数だけ前記１の監視センターとの間の接続の確立に失敗した場合、前記ＬＴＥ端末の常時接続先を切換えること、としてもよい。 In the wireless remote monitoring system of the present invention, the elevator monitoring device switches the constant connection destination of the LTE terminal when the LTE terminal fails to establish a connection with the one monitoring center a predetermined number of times. It is good.
　これにより、煩雑に常時接続先のアクセスポイントの切換えが発生することを抑制できる。 This makes it possible to prevent troublesome switching of the access point to be connected constantly.
　本発明の無線遠隔監視システムにおいて、前記エレベーター監視装置は、前記エレベーターのかごの中に乗客が閉じ込められた状態で、前記ＬＴＥ端末が前記１の監視センターとの間の接続の確立に失敗した場合、前記ＬＴＥ端末の常時接続先を切換えること、としてもよい。 In the wireless remote monitoring system of the present invention, the elevator monitoring device is configured when the LTE terminal fails to establish a connection with the one monitoring center in a state where passengers are confined in the elevator car. , The permanent connection destination of the LTE terminal may be switched.
　これにより、閉じ込めの発生とＬＴＥ端末と常時接続先のアクセスポイントとの間の接続障害の発生とが重なった場合に、エレベーター監視装置と監視センターとの間のデータの授受を短時間で回復させることができる。 As a result, when the occurrence of confinement and the occurrence of a connection failure between the LTE terminal and the always-on access point overlap, data exchange between the elevator monitoring device and the monitoring center can be recovered in a short time. be able to.
　本発明の無線遠隔監視システムにおいて、前記エレベーター監視装置は、地震が発生した際には、前記ＬＴＥ端末の常時接続先を切換えずに、前記１のアクセスポイントおよび前記他のアクセスポイントと異なる第３アクセスポイントを介して地震時のエレベーター状態信号を地震時データ受信サーバに送信すること、としてもよい。 In the wireless remote monitoring system of the present invention, when the earthquake occurs, the elevator monitoring device is different from the one access point and the other access points without switching the permanent connection destination of the LTE terminal. It is good also as transmitting the elevator state signal at the time of an earthquake to the data reception server at the time of an earthquake via an access point.
　地震発生の場合には多くのＬＴＥ端末とアクセスポイントとの間の接続障害が発生することが想定される。この場合、多くのＬＴＥ端末のアクセスポイントを一度に切換えてしまうと他の監視センターの監視能力を超えてしまう場合がある。このため、地震時にはアクセスポイントの切換を行わずに第３のアクセスポイントを介してデータを地震時データ受信サーバに送信し、無線遠隔監視システム全体の機能が低下することを抑制できる。 In the event of an earthquake, it is assumed that connection failures between many LTE terminals and access points will occur. In this case, if the access points of many LTE terminals are switched at once, the monitoring capability of other monitoring centers may be exceeded. For this reason, it is possible to suppress the deterioration of the function of the entire wireless remote monitoring system by transmitting data to the earthquake data reception server via the third access point without switching the access point during an earthquake.
　本発明の無線遠隔監視システムにおいて、前記１の監視センターは、前記エレベーター監視装置との間の接続が確立できない場合に、ＳＭＳで常時接続先切換え指令のショートメールを前記ＬＴＥ端末に発信し、前記エレベーター監視装置は、前記ＬＴＥ端末が前記ショートメールを受信した場合に、前記ＬＴＥ端末の常時接続先を前記１のアクセスポイントから前記他の監視センターが接続されている他のアクセスポイントに切換えて、前記他の監視センターとの間でデータの授受を行うこと、としてもよい。 In the wireless remote monitoring system of the present invention, when the connection with the elevator monitoring apparatus cannot be established, the one monitoring center transmits a short mail of a constant connection destination switching command to the LTE terminal by SMS, and When the LTE terminal receives the short mail, the elevator monitoring device switches the always-connected destination of the LTE terminal from the one access point to another access point to which the other monitoring center is connected, Data may be exchanged with the other monitoring center.
　通常、ＬＴＥ端末の常時接続先の切換えは、エレベーター監視装置が行い、監視センターから直接切換えることができないが、これにより、監視センターからアクセスポイントの切換えを行うことが可能となる。 Ordinarily, switching of the permanent connection destination of the LTE terminal is performed by the elevator monitoring device and cannot be switched directly from the monitoring center, but this makes it possible to switch the access point from the monitoring center.
　本発明の無線遠隔監視システムは、第１国に設置されたエレベーターに接続されて前記エレベーターの運行状態を監視するエレベーター監視装置と、前記エレベーター監視装置に接続され、ＬＴＥ回線網の中の１のアクセスポイントに常時接続されるＬＴＥ端末と、前記第１国に設置され、前記ＬＴＥ回線網の前記１のアクセスポイントに接続されて前記エレベーター監視装置との間でデータの授受を行う１の監視センターと、を含み、前記ＬＴＥ回線網を介して前記エレベーターの遠隔監視を行う無線遠隔監視システムであって、前記エレベーター監視装置は、前記１の監視センターとの間の接続が確立できない場合に、前記ＬＴＥ端末の常時接続先を前記１のアクセスポイントから、前記第１国と異なる第２国に設置された他の監視センターが接続されている他のアクセスポイントに切換えて、前記第２国の前記他の監視センターとの間でデータの授受を行うこと、を特徴とする。また、本発明の無線遠隔監視システムにおいて、前記他の監視センターは、前記第２国の電話通信網を介して前記ＬＴＥ回線網に接続されていること、としてもよい。 The wireless remote monitoring system of the present invention is connected to an elevator installed in a first country and monitors the operation state of the elevator, and is connected to the elevator monitoring device and is connected to one of the LTE network. An LTE terminal that is always connected to an access point, and a monitoring center that is installed in the first country and that is connected to the first access point of the LTE network and exchanges data with the elevator monitoring device And a wireless remote monitoring system for remotely monitoring the elevator via the LTE network, wherein the elevator monitoring device cannot establish a connection with the one monitoring center, The other end of the LTE terminal is connected from the one access point to another monitoring center installed in a second country different from the first country. It is switched to other access points terpolymer is connected, characterized in that, for exchanging data with the other monitoring centers of the second country. In the wireless remote monitoring system of the present invention, the other monitoring center may be connected to the LTE network via the second country telephone communication network.
　これにより、他の国に設置された監視センターでエレベーターの遠隔監視のバックアップを行うことができる。 This enables backup of remote monitoring of elevators at monitoring centers installed in other countries.
　本発明は、ＬＴＥ回線網を用いた遠隔監視システムにおいて、ＬＴＥ回線に異常が発生した場合に、簡便な方法で遠隔監視のバックアップを行うことができる。 The present invention can perform remote monitoring backup by a simple method when an abnormality occurs in the LTE line in the remote monitoring system using the LTE line network.

　＜無線遠隔監視システムの構成＞
　以下、図面を参照しながら実施形態の無線遠隔監視システム１００について説明する。図１に示すように、第１、第２エレベーター１１，２１の遠隔監視を行う無線遠隔監視システム１００は、第１、第２エレベーター監視装置１２，２２（以下、ＭＯＰ１，ＭＯＰ２という）と、第１、第２ＬＴＥ端末１３，２３（以下、ＬＴＥ１、ＬＴＥ２という）と、ＬＴＥ回線網３０と、第１、第２監視センター４１、４２と、第１、第２地震時データ受信サーバ４３，４４とを含んでいる。 <Configuration of wireless remote monitoring system>
Hereinafter, a wireless remote monitoring system 100 according to an embodiment will be described with reference to the drawings. As shown in FIG. 1, a wireless remote monitoring system 100 for remotely monitoring the first and second elevators 11 and 21 includes first and second elevator monitoring devices 12 and 22 (hereinafter referred to as MOP1 and MOP2), 1, second LTE terminals 13 and 23 (hereinafter referred to as LTE 1 and LTE 2), LTE network 30, first and second monitoring centers 41 and 42, first and second earthquake data receiving servers 43 and 44, Is included.
　第１地域、第２地域に設置されている第１、第２監視センター４１，４２は、それぞれ、第１地域、第２地域に設置されている第１、第２エレベーター１１，２１の監視を行う。なお、第１、第２監視センター４１，４２は、それぞれ複数台のエレベーター１１，２１を監視してもよい。ここで、第１地域、第２地域とは、例えば、東日本と西日本とであってもよい。この場合、東日本に設置されているエレベーターの遠隔監視は東日本に設置されている監視センターが行い、西日本に設置されているエレベーターの遠隔監視は西日本に設置されている監視センターが行う。第１、第２監視センター４１，４２は、第１、第２エレベーター１１，２１の各データを格納するサーバと操作盤などで構成されてもよい。 The first and second monitoring centers 41 and 42 installed in the first area and the second area respectively monitor the first and second elevators 11 and 21 installed in the first area and the second area, respectively. Do. The first and second monitoring centers 41 and 42 may monitor a plurality of elevators 11 and 21, respectively. Here, the first region and the second region may be, for example, eastern Japan and western Japan. In this case, remote monitoring of elevators installed in eastern Japan is performed by a monitoring center installed in eastern Japan, and remote monitoring of elevators installed in western Japan is performed by a monitoring center installed in western Japan. The first and second monitoring centers 41 and 42 may be configured by a server that stores data of the first and second elevators 11 and 21, an operation panel, and the like.
　ＭＯＰ１，ＮＯＰ２は、それぞれ第１、第２エレベーター１１、２１に接続されて第１、第２エレベーター１１，２１の各制御装置から第１、第２エレベーター１１，２１の運行状態を示すデータ、或いは故障信号等を取得し、格納する。ＭＯＰ１，ＭＯＰ２には、それぞれＬＴＥ１、ＬＴＥ２が接続されている。ＭＯＰ１，ＭＯＰ２は内部に情報処理を行うＣＰＵとメモリとを含むコンピュータで構成してもよい。 MOP1 and NOP2 are connected to the first and second elevators 11 and 21, respectively, and the data indicating the operation status of the first and second elevators 11 and 21 from the control devices of the first and second elevators 11 and 21, or Acquire and store failure signals. LTE1 and LTE2 are connected to MOP1 and MOP2, respectively. The MOP1 and MOP2 may be configured by a computer including a CPU that performs information processing and a memory therein.
　ＬＴＥ回線網３０は、ＡＰＮ１～ＡＰＮ４の４つのアクセスポイントを含んでいる。ＬＴＥ１は１のアクセスポイントであるＡＰＮ１に、ＬＴＥ２は他のアクセスポイントであるＡＰＮ２に常時接続されている。第１監視センター４１、第２監視センター４２は、それぞれ、ＡＰＮ１，ＡＰＮ２に接続されている。また、第１、第２監視センター４１，４２には、それぞれ、ＬＴＥ１、ＬＴＥ２にショートメールを発信するショートメールシステム（以下、ＳＭＳという）が取付けられている。 The LTE network 30 includes four access points APN1 to APN4. LTE1 is always connected to APN1, which is one access point, and LTE2 is always connected to APN2, which is another access point. The first monitoring center 41 and the second monitoring center 42 are connected to APN1 and APN2, respectively. The first and second monitoring centers 41 and 42 are each provided with a short mail system (hereinafter referred to as SMS) that transmits a short mail to LTE1 and LTE2.
　第１地域、第２地域に設置されている第１地震時データ受信サーバ４３、第２地震時データ受信サーバ４４は、それぞれ、ＡＰＮ３、ＡＰＮ４に接続されている。 The first earthquake data receiving server 43 and the second earthquake data receiving server 44 installed in the first area and the second area are connected to APN3 and APN4, respectively.
　ＬＴＥ回線の接続状態が正常の場合には、図１の一点鎖線９１に示すように、ＭＯＰ１は、第１エレベーター１１の運行状態を示すデータ或いは故障信号等をエレベーター１１の制御装置から取得し、格納すると共に、そのデータをＬＴＥ１、ＡＰＮ１を介して第１監視センター４１に送信する。また、第１監視センター４１は、ポーリングによってＡＰＮ１、ＬＴＥ１を介してＭＯＰ１にアクセスし、ＭＯＰ１から第１エレベーター１１の運転データ等を取得する。また、第１監視センター４１は、ＡＰＮ１、ＬＴＥ１を介して第１エレベーター１１のかごの中のインターホンに接続し、かごの中の乗客と通話する。このように、ＭＯＰ１と第１監視センター４１とは、ＡＰＮ１を介してデータの授受を行う。 When the connection state of the LTE line is normal, as shown by the one-dot chain line 91 in FIG. 1, the MOP 1 acquires data indicating the operation state of the first elevator 11 or a failure signal from the control device of the elevator 11, The data is stored and the data is transmitted to the first monitoring center 41 via the LTE 1 and the APN 1. In addition, the first monitoring center 41 accesses MOP1 via APN1 and LTE1 by polling, and acquires operation data and the like of the first elevator 11 from MOP1. Moreover, the 1st monitoring center 41 connects with the intercom in the cage | basket | car of the 1st elevator 11 via APN1 and LTE1, and talks with the passenger in a cage | basket | car. In this way, the MOP 1 and the first monitoring center 41 exchange data via the APN 1.
　同様に、ＭＯＰ２は、図１の一点鎖線９２に示すようにＡＰＮ２を介して第２監視センター４２とデータの授受を行う。 Similarly, the MOP 2 exchanges data with the second monitoring center 42 via the APN 2 as indicated by a one-dot chain line 92 in FIG.
　地震が発生した場合には、ＭＯＰ１は、図１の二点鎖線９３に示すようにＬＴＥ１をＡＰＮ４に接続し、図１の破線９４に示すように第２地震時データ受信サーバ４４に地震発生時の運転データや故障信号などのエレベーター状態信号を出力する。同様に、ＭＯＰ２は、図１の二点鎖線９５に示すようにＬＴＥ２をＡＰＮ３に接続し、図１の破線９６に示すように第１地震時データ受信サーバ４３に地震発生時の運転データや故障信号などのエレベーター状態信号を出力する。このように、ＭＯＰ１，ＭＯＰ２は地震発生時には、第１、第２エレベーター１１，２１が設置されている地域と異なる地域に設置されている地震時データ受信サーバにデータを送信する。なお、ＡＰＮ３，ＡＰＮ４は第３アクセスポイントに相当する。 When an earthquake occurs, the MOP 1 connects the LTE 1 to the APN 4 as shown by a two-dot chain line 93 in FIG. 1, and sends the second earthquake data reception server 44 at the time of the earthquake as shown by a broken line 94 in FIG. Elevator status signals such as driving data and failure signals are output. Similarly, the MOP 2 connects the LTE 2 to the APN 3 as indicated by a two-dot chain line 95 in FIG. 1, and the operation data or failure at the time of the earthquake occurs in the first earthquake data receiving server 43 as indicated by the broken line 96 in FIG. Elevator status signals such as signals are output. As described above, when an earthquake occurs, MOP1 and MOP2 transmit data to an earthquake data receiving server installed in an area different from the area where the first and second elevators 11 and 21 are installed. APN3 and APN4 correspond to a third access point.
　＜ＭＯＰ１の動作＞
　次に、図２、図３を参照しながらＬＴＥ１とＡＰＮ１との間の接続障害が発生した場合の無線遠隔監視システム１００の動作について説明する。なお、以下の説明では、ＭＯＰ１の動作について説明する。なお、ＭＯＰ２の動作はＭＯＰ１の動作と同様である。 <Operation of MOP1>
Next, the operation of the wireless remote monitoring system 100 when a connection failure between the LTE 1 and the APN 1 occurs will be described with reference to FIGS. In the following description, the operation of MOP1 will be described. The operation of MOP2 is the same as that of MOP1.
　図２のステップＳ１０１に示すように、ＭＯＰ１は起動時にＬＴＥ１の常時接続先をＡＰＮ１とする。ＭＯＰ１は,起動時にＬＴＥ１の常時接続先がＡＰＮ１となっていない場合には、ＬＴＥ１の常時接続先をＡＰＮ１としてＬＴＥ１を再起動してＬＴＥの常時接続先をＬＴＥ１とする。 As shown in step S101 of FIG. 2, MOP1 sets the always-connected destination of LTE1 to APN1 when it is activated. When the always-connected destination of LTE1 is not APN1 at the time of activation, MOP1 restarts LTE1 with the always-connected destination of LTE1 as APN1, and sets the always-connected destination of LTE to LTE1.
　図２のステップＳ１０２に示すように、ＭＯＰ１は、ＬＴＥ１とＡＰＮ１との接続が確立しているかどうかを判断する。ＡＰＮ１との接続が確立している場合には接続障害が発生していないと判断して、図２のステップＳ１０３に進み、ＬＴＥ１とＡＰＮ１との常時接続を保持し、ステップＳ１０４に示すように、１の監視センターである第１監視センター４１との間でデータの授受を行う。 As shown in step S102 of FIG. 2, MOP1 determines whether or not the connection between LTE1 and APN1 has been established. If the connection with APN1 is established, it is determined that no connection failure has occurred, and the process proceeds to step S103 in FIG. 2 to maintain a constant connection between LTE1 and APN1, and as shown in step S104, Data is exchanged with the first monitoring center 41 which is one monitoring center.
　一方、ＭＯＰ１は、図２のステップＳ１０２で、ＬＴＥ１とＡＰＮ１との接続が確立できない場合には通信障害が発生していると判断して、図２のステップＳ１０５に進む。ステップＳ１０５において、ＭＯＰ１は、例えば、第１エレベーター１１のインターホンボタンが押し続けられている、或いは、戸開ボタンが押し続けられているようにかごの中に乗客が閉じ込められている状態が発生していると判断した場合には、図２のステップＳ１０８に進んでＬＴＥ１の常時接続先をＡＰＮ１からＡＰＮ２に切換える。これにより、図３に示すように、ＬＴＥ１はＡＰＮ２と常時接続される。ＭＯＰ１は図２のステップＳ１０９に進んで、図３の一点鎖線９１ａに示すようにＡＰＮ２に接続されている他の監視センターである第２監視センター４２との間でデータの授受を行う。 On the other hand, if the connection between LTE1 and APN1 cannot be established in step S102 of FIG. 2, MOP1 determines that a communication failure has occurred, and proceeds to step S105 of FIG. In step S105, for example, the MOP 1 has a state in which the intercom button of the first elevator 11 is kept pressed or the passenger is trapped in the car so that the door open button is kept pressed. If it is determined, the process proceeds to step S108 in FIG. 2 to switch the constant connection destination of LTE1 from APN1 to APN2. Thereby, as shown in FIG. 3, LTE1 is always connected with APN2. The MOP1 proceeds to step S109 in FIG. 2, and exchanges data with the second monitoring center 42, which is another monitoring center connected to the APN 2, as indicated by a one-dot chain line 91a in FIG.
　これにより、かごの中の乗客は、インターホンを通じて第２監視センター４２の監視員と通話することができるようになる。このように、閉じ込めが発生とＡＰＮ１と接続障害の発生とが重なった場合に、ＭＯＰ１と監視センターとの間のデータの授受を短時間で回復させることができる。 This allows passengers in the car to talk to the monitor at the second monitoring center 42 through the intercom. As described above, when the confinement occurs and the APN1 and the connection failure overlap, the data exchange between the MOP1 and the monitoring center can be recovered in a short time.
　また、ＭＯＰ１は、図２のステップＳ１０５でＮＯと判断した場合には、図２のステップＳ１０６に進んで、所定回数だけ接続回復動作をしたかどうかを確認する。そして、図２のステップＳ１０６でＮＯと判断した場合には、図２のステップＳ１０７に進んで、ＬＴＥ１にＡＰＮ１との接続動作を行わせ、図２のステップＳ１０２に戻ってＡＰＮ１との接続が確立したかどうか確認する。ここで、所定回数は、自由に設定できるが、例えば、３回、５回、１０回等に設定してもよい。 Further, if the MOP 1 determines NO in step S105 in FIG. 2, the process proceeds to step S106 in FIG. 2 to confirm whether or not the connection recovery operation has been performed a predetermined number of times. If NO is determined in step S106 of FIG. 2, the process proceeds to step S107 of FIG. 2 to cause LTE1 to perform the connection operation with APN1, and the process returns to step S102 of FIG. 2 to establish the connection with APN1. Check if you did. Here, the predetermined number of times can be set freely, but may be set to three times, five times, ten times, or the like.
　ＭＯＰ１は、接続回復動作でＡＰＮ１との接続が確立された場合には、図２のステップＳ１０２でＹＥＳと判断して図２のステップＳ１０３、Ｓ１０４に進み、ＡＰＮ１を介して第１監視センター４１との間でデータの授受を行う。 If the connection with the APN 1 is established by the connection recovery operation, the MOP 1 determines YES in step S102 in FIG. 2 and proceeds to steps S103 and S104 in FIG. 2, and the first monitoring center 41 via the APN 1 Send and receive data between.
　一方、所定回数だけ接続回復動作を行ってもＡＰＮ１との接続を確立できず、接続障害の状態が続く場合には、ＭＯＰ１は、図２のステップＳ１０２、Ｓ１０６でＹＥＳと判断して図２のステップＳ１０８に進んでＬＴＥ１の常時接続先を図３に示すようにＡＰＮ１からＡＰＮ２に切換え、図２のステップＳ１０９に進んで図３の一点鎖線９１ａに示すように、ＡＰＮ２に接続されている他の監視センターである第２監視センター４２との間でデータの授受を行う。 On the other hand, if the connection with the APN 1 cannot be established even if the connection recovery operation is performed a predetermined number of times, and the connection failure state continues, the MOP 1 determines YES in steps S102 and S106 in FIG. Proceeding to step S108, the constant connection destination of LTE1 is switched from APN1 to APN2 as shown in FIG. 3, and proceeding to step S109 of FIG. Data is exchanged with the second monitoring center 42 which is a monitoring center.
　ＭＯＰ１は、図２のステップＳ１０９で第２監視センター４２との間でデータの授受を行ったら、図２のステップＳ１１０に示すように、所定の期間が経過するまで、ＬＴＥ１とＡＰＮ２との常時接続状態を保持する。ここで、所定の期間は、例えば、３０分、或いは、１時間などに設定することができる。 When the MOP 1 exchanges data with the second monitoring center 42 in step S109 in FIG. 2, as shown in step S110 in FIG. 2, the MOP 1 always connects the LTE 1 and the APN 2 until a predetermined period elapses. Keep state. Here, the predetermined period can be set to 30 minutes or 1 hour, for example.
　このように、所定回数だけ接続回復動作を行っても接続障害が継続する場合に常時接続先のアクセスポイントの切換えを行い、所定期間だけ切換え状態を保持するので、煩雑に常時接続先のアクセスポイントの切換えが発生することを抑制できる。また、アクセスポイントをＡＰＮ２に切換えた際の第２監視センター４２からＭＯＰ１へのアクセスを確実に行うことができる。 In this way, if the connection failure continues even if the connection recovery operation is performed a predetermined number of times, the access point of the connection destination is always switched and the switching state is maintained for a predetermined period of time, so that the access point of the connection destination is always complicated. Can be prevented from occurring. Further, it is possible to reliably access the MOP 1 from the second monitoring center 42 when the access point is switched to the APN 2.
　ＭＯＰ１は、所定期間が経過し図２のステップＳ１１０でＹＥＳと判断したら、図２のステップＳ１１１に進んでＬＴＥ１とＡＰＮ１との接続動作を実行する。そして、図２のステップＳ１１２でＬＴＥ１とＡＰＮ１との接続が確立したら、図２のステップＳ１１３に進み、ＬＴＥ１の常時接続先をＡＰＮ２からＡＰＮ１に戻し、図２のステップＳ１０３に進んでＬＴＥ１をＡＰＮ１と常時接続する。すると、無線遠隔監視システム１００は、図１に示す系統構成にもどる。そして、ＭＯＰ１は、図２のステップＳ１０４に進んで第１監視センター４１との間でデータの授受を行う。 When the predetermined period has elapsed and YES is determined in step S110 in FIG. 2, the MOP1 proceeds to step S111 in FIG. 2 and executes the connection operation between LTE1 and APN1. When the connection between LTE1 and APN1 is established in step S112 of FIG. 2, the process proceeds to step S113 of FIG. 2, the LTE1 constant connection destination is returned from APN2 to APN1, and the process proceeds to step S103 of FIG. Connect always. Then, the wireless remote monitoring system 100 returns to the system configuration shown in FIG. Then, the MOP 1 proceeds to step S104 in FIG. 2 to exchange data with the first monitoring center 41.
　一方、ＭＯＰ１は、図２のステップＳ１１２でＬＴＥ１とＡＰＮ１との接続が確立できない場合には、図２のステップＳ１１３に進んで、所定のインターバルだけ待機し、所定のインターバルだけ時間が経過したら、図２のステップＳ１１１に戻ってＬＴＥ１とＡＰＮ１との接続動作を実行する。ここで、所定のインターバルは、例えば、１０分、或いは３０分程度とすることができる。 On the other hand, if the connection between LTE1 and APN1 cannot be established in step S112 in FIG. 2, the MOP1 proceeds to step S113 in FIG. 2 and waits for a predetermined interval. Returning to step S111 of 2, the connection operation between LTE1 and APN1 is executed. Here, the predetermined interval can be set to about 10 minutes or 30 minutes, for example.
　ＭＯＰ１は、ＬＴＥ１とＡＰＮ１との接続が確立するまで、図２のステップＳ１１１からステップＳ１１３の動作を繰り返し、ＬＴＥ１とＡＰＮ１との接続が確立したら、図２のステップＳ１１３でＬＴＥ１の常時接続先をＡＰＮ２からＡＰＮ１に戻し、図２のステップＳ１０３、Ｓ１０４に進んでＬＴＥ１をＡＰＮ１と常時接続して第１監視センター４１との間でデータの授受を行う。 MOP1 repeats the operations from step S111 to step S113 in FIG. 2 until the connection between LTE1 and APN1 is established. When the connection between LTE1 and APN1 is established, the constant connection destination of LTE1 is changed to APN2 in step S113 in FIG. 2 to return to APN1 and proceed to steps S103 and S104 in FIG. 2 to connect LTE 1 to APN1 at all times and exchange data with first monitoring center 41.
　このように、ＭＯＰ１はＬＴＥ１の所定期間経過後にＡＰＮ１との接続を確立する動作を所定のインターバルで継続して行い、ＬＴＥ１とＡＰＮ１との接続が確立したら、常時接続先をＡＰＮ２からＡＰＮ１に戻して第１監視センター４１との間でデータの授受を行うので、遠隔監視のバックアップで高くなっていた第２監視センター４２の負荷を下げて、通常の状態に戻すことができる。 As described above, MOP1 continuously performs an operation of establishing a connection with APN1 after a predetermined period of LTE1 at a predetermined interval, and when a connection between LTE1 and APN1 is established, the connection destination is always returned from APN2 to APN1. Since data is exchanged with the first monitoring center 41, the load on the second monitoring center 42, which has been high due to the remote monitoring backup, can be reduced to return to the normal state.
　＜第１、第２監視センターの動作＞
　次に図４、図５を参照しながら第１監視センター４１の動作について説明する。なお、第２監視センター４２の動作は、第１監視センター４１の動作と同様である。 <Operation of the first and second monitoring centers>
Next, the operation of the first monitoring center 41 will be described with reference to FIGS. The operation of the second monitoring center 42 is the same as the operation of the first monitoring center 41.
　第１監視センター４１は、図４のステップＳ２０１に示すようにＭＯＰ１にポーリング信号を発信し、ＭＯＰ１に第１エレベーター１１の運転データ等を発信させる。従って、図５に示すように、第１監視センター４１とＡＰＮ１との間の接続が不良となった場合、ＭＯＰ１は第１監視センター４１からポーリング信号を受信せず、データの発信を行わないので、第１監視センター４１との間に接続障害が発生していること検知できない場合がある。この場合、ＭＯＰ１は常時接続先の切換えを行わない。一方、第１監視センター４１は、直接、ＬＴＥ１にアクセスしてＬＴＥ１の常時接続先を切換えることはできない。このため、ＭＯＰ１と第１監視センター４１との間のデータ授受ができない状態が継続してしまう場合がある。 The first monitoring center 41 transmits a polling signal to the MOP 1 as shown in step S201 of FIG. 4, and causes the MOP 1 to transmit the operation data of the first elevator 11 and the like. Therefore, as shown in FIG. 5, when the connection between the first monitoring center 41 and the APN 1 becomes defective, the MOP 1 does not receive a polling signal from the first monitoring center 41 and does not transmit data. In some cases, it may not be possible to detect that a connection failure has occurred with the first monitoring center 41. In this case, MOP1 does not always switch the connection destination. On the other hand, the first monitoring center 41 cannot directly access the LTE 1 to switch the permanent connection destination of the LTE 1. For this reason, a state where data cannot be exchanged between the MOP 1 and the first monitoring center 41 may continue.
　そこで、第１監視センター４１は、図４のステップＳ２０１のＭＯＰ１へのポーリング動作の際にポーリング信号の送受信を行えない場合には、図４のステップＳ２０２でＭＯＰ１との接続が確立していないと判断して図４のステップＳ２０４に進んで所定回数だけポーリング動作に失敗したかどうかを判断する。そして、所定の回数だけポーリング動作に失敗した場合には、図４のステップＳ２０４でＹＥＳと判断して図４のステップＳ２０５に進み、図５に示すように、ＬＴＥ回線網において通信のバックアップを行うには、ＳＭＳ４５からＬＴＥ１に常時接続先切換え指令のショートメールを送信する。ＬＴＥ１は、このショートメールを受信したら所定の信号をＭＯＰ１に出力する。ＭＯＰ１は、この所定の信号が入力されたら、図２のステップＳ１０８、Ｓ１０９を実行し、図５に示すように常時接続先のアクセスポイントをＡＰＮ１からＡＰＮ２に切換える。この常時接続先のアクセスポイントの切換えには１～２分程度の時間がかかる。 Therefore, if the first monitoring center 41 cannot transmit or receive a polling signal during the polling operation to MOP1 in step S201 in FIG. 4, it is assumed that the connection with MOP1 has not been established in step S202 in FIG. The process proceeds to step S204 in FIG. 4 to determine whether the polling operation has failed a predetermined number of times. If the polling operation has failed a predetermined number of times, YES is determined in step S204 in FIG. 4, and the process proceeds to step S205 in FIG. 4, where communication backup is performed in the LTE network as shown in FIG. The SMS 45 always sends a short mail of a connection destination switching command to the LTE 1. When LTE1 receives this short mail, it outputs a predetermined signal to MOP1. When this predetermined signal is input, MOP1 executes steps S108 and S109 of FIG. 2, and switches the access point to be always connected from APN1 to APN2 as shown in FIG. It takes about 1 to 2 minutes to change the access point of the constant connection destination.
　第１監視センター４１がＳＭＳでＬＴＥ１にショートメールを発信した２～３分後で常時接続先のアクセスポイントの切換えが終了した頃に、第２監視センター４２は、図２のステップＳ２０６に示すように、ＭＯＰ１へのポーリング動作を行い、図２のステップＳ２０７、Ｓ２０８、図５の一点鎖線９１ａに示すように、ＭＯＰ１から第１エレベーター１１の運転データ等を取得する。第２監視センター４２は、図４のステップＳ２０７、Ｓ２０８に示すように、所定期間だけＭＯＰ１との間のデータ授受を行った後、図４のステップＳ２０９に進んでＭＯＰ１との間のデータ授受を停止し、図４のステップ２０１に戻って第１監視センター４１からＭＯＰ１へのポーリング動作を行う。そして、図４のステップＳ２０２で、ＭＯＰ１との接続が確立したら図４のステップＳ２０３に進み、第１監視センター４１とＭＯＰ１との間でデータの授受を行う。 As shown in step S206 of FIG. 2, when the first monitoring center 41 completes the switching of the access point to which it is always connected two to three minutes after sending the short mail to the LTE 1 by SMS. In addition, a polling operation to the MOP 1 is performed, and operation data and the like of the first elevator 11 are acquired from the MOP 1 as shown in steps S207 and S208 of FIG. 2 and the one-dot chain line 91a of FIG. As shown in steps S207 and S208 in FIG. 4, the second monitoring center 42 performs data exchange with the MOP1 for a predetermined period, and then proceeds to step S209 in FIG. 4 to exchange data with the MOP1. The process is stopped, and the process returns to step 201 in FIG. 4 to perform the polling operation from the first monitoring center 41 to the MOP 1. When the connection with MOP1 is established in step S202 of FIG. 4, the process proceeds to step S203 of FIG. 4, and data is exchanged between the first monitoring center 41 and MOP1.
　以上のような動作により、第１監視センター４１からＬＴＥ１の常時接続先のアクセスポイントを切換えることができるので、第１監視センター４１とＡＰＮ１との間で接続障害が発生した場合でも、遠隔監視のバックアップを行うことができる。 Through the operation as described above, the access point to which the LTE 1 is always connected can be switched from the first monitoring center 41. Therefore, even if a connection failure occurs between the first monitoring center 41 and the APN 1, remote monitoring can be performed. Backup can be done.
　＜地震発生の場合の動作＞
　地震発生の場合には多くのＬＴＥ１とＡＰＮ１との間の接続障害が発生することが想定される。この場合、多くのＬＴＥ１のアクセスポイントをＡＰＮ１からＡＰＮ２一度に切換えてしまうと第２監視センター４２の監視能力を超えてしまう場合がある。そこで、ＭＯＰ１は、地震が発生によりＬＴＥ１とＡＰＮ１との間に接続障害が発生した場合には、ＬＴＥ１の常時接続先をＡＰＮ１からＡＰＮ２に切換えずにＡＰＮ４を介して地震時のエレベーター状態信号を第２地震時データ受信サーバ４４に送信する。これにより、無線遠隔監視システム１００全体の機能が低下することを抑制する。地震時のＭＯＰ２の動作は、ＭＯＰ１の動作と同様である。 <Operation when an earthquake occurs>
In the event of an earthquake, it is assumed that many connection failures between LTE1 and APN1 will occur. In this case, if many LTE 1 access points are switched from APN 1 to APN 2 at once, the monitoring capability of the second monitoring center 42 may be exceeded. Therefore, when a connection failure occurs between LTE1 and APN1 due to the occurrence of an earthquake, MOP1 sends an elevator status signal at the time of the earthquake via APN4 without switching the permanent connection destination of LTE1 from APN1 to APN2. 2 Transmit to the data receiving server 44 at the time of earthquake. Thereby, it is suppressed that the function of the whole radio | wireless remote monitoring system 100 falls. The operation of MOP2 during an earthquake is the same as that of MOP1.
　＜他の実施形態の無線遠隔監視システム＞
　図６、図７を参照しながら、他の実施形態の無線遠隔監視システム２００について説明する。先に図１を参照して説明した無線遠隔監視システム１００と同様の部分には、同様の符号を付して説明は省略する。 <Wireless Remote Monitoring System of Other Embodiment>
A wireless remote monitoring system 200 according to another embodiment will be described with reference to FIGS. 6 and 7. Components similar to those of the wireless remote monitoring system 100 described above with reference to FIG.
　無線遠隔監視システム２００は、図６に示すように、第１エレベーター１１、第１監視センター４１が第１国に設置されており、第２エレベーター２１、第２監視センター４２が第１国と異なる第２国に設置されているものである。通常は、第１国に設置されている第１エレベーター１１の遠隔監視は第１国に設置されている第１監視センター４１が行い、第２国に設置とされている第２エレベーター２１の遠隔監視は、第２国の第２監視センター４２が行っている。 As shown in FIG. 6, in the wireless remote monitoring system 200, the first elevator 11 and the first monitoring center 41 are installed in the first country, and the second elevator 21 and the second monitoring center 42 are different from the first country. It is installed in the second country. Normally, the first elevator 11 installed in the first country is remotely monitored by the first monitoring center 41 installed in the first country, and the second elevator 21 installed in the second country is remotely monitored. The monitoring is performed by the second monitoring center 42 in the second country.
　図７に示すようにＬＴＥ１とＡＰＮ１との間の接続が確立できいな場合には、ＭＯＰ１は,ＬＴＥ１の常時接続先のアクセスポイントを第２監視センター４２が接続されているＡＰＮ２に切換える。そして、第１国に設置されている第１エレベーター１１の遠隔監視を第２国に設置されている第２監視センター４２によって実行する。 As shown in FIG. 7, when the connection between LTE1 and APN1 cannot be established, MOP1 switches the access point that is always connected to LTE1 to APN2 to which the second monitoring center 42 is connected. And the remote monitoring of the 1st elevator 11 installed in the 1st country is performed by the 2nd monitoring center 42 installed in the 2nd country.
　これにより、より広範囲に設置されている多くのエレベーターの遠隔監視のバックアップを行うことができる。 This makes it possible to back up remote monitoring of many elevators installed in a wider area.
　なお、第２監視センター４２は、第２国の電話通信網を介してＬＴＥ回線網３０に接続されているように構成してもよい。 Note that the second monitoring center 42 may be configured to be connected to the LTE network 30 via the telephone communication network of the second country.
