The management facility needs to monitor not only the operating state of each power receiving / transforming facility but also the self-inspection state of the monitoring device and the transmission device. For example, in Patent Document 1, in a (device monitoring control) system for managing a drainage station (building facility), a monitoring device having a monitoring function including a device response monitoring function and a response function and a device having a response function There is a device monitoring control system in which a monitoring control device is connected to a communication network.

しかし、伝送装置と監視装置がそれぞれ別個の機器で構成される場合には、伝送装置、即ち、監視装置の監視信号を収集してネットワークに送信する集線装置や、監視装置、また受変電設備（機器）の異常検出や異常を検出した場合に管理設備で故障分離が可能な警報伝達をすることが困難な問題があった。   However, when the transmission device and the monitoring device are configured as separate devices, the transmission device, that is, the concentrator that collects the monitoring signal of the monitoring device and transmits it to the network, the monitoring device, and the receiving / transforming equipment ( There is a problem that it is difficult to transmit alarms that can be separated into faults in the management equipment when an abnormality is detected.

また、故障分離に必要な識別情報ＩＤを付与して管理する伝送装置、又はその様な管理機能を備えた伝送装置と監視機能を備えた機器監視制御装置は装置コストを要する問題があった。
特開２００７−２５１６９７ Further, a transmission apparatus that assigns and manages identification information ID necessary for fault isolation, or a transmission apparatus that has such a management function and a device monitoring and control apparatus that has a monitoring function have a problem of requiring apparatus cost.

以下本発明の実施形態について、図面を参照して説明する。図１は、本発明の実施形態に関わる遠隔監視システムの構成図である。   Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram of a remote monitoring system according to an embodiment of the present invention.

図１において、遠隔監視システムは、伝送路１に接続される集線装置（第２の集線装置を構成している）２ａ、集線装置（第１の集線装置を構成している）２ｂ…２ｎ、各集線装置２ａ〜２ｎに接続される主監視装置４、従監視装置５、表示装置７、および集線装置用応答装置２１ａ、２１ｂ…２１ｎを備える。集線装置用応答装置２１ａは、第２の集線装置用応答装置を構成し、集線装置用応答装置２１ｂ…２１ｎは第１の集線装置用応答装置を構成している。なお、ここで従監視装置５は、１台のみ示されているが、表示装置７を含めて３台以上（図示せず）設置されていてもよい。   In FIG. 1, the remote monitoring system includes a line concentrator (which constitutes a second line concentrator) 2a, a line concentrator (which constitutes a first line concentrator) 2b... 2n connected to the transmission line 1. The main monitoring device 4, the secondary monitoring device 5, the display device 7, and the concentrator response devices 21a, 21b,... 21n connected to the respective concentrators 2a to 2n. The concentrator response device 21a constitutes a second concentrator response device, and the concentrator response devices 21b... 21n constitute a first concentrator response device. Although only one slave monitoring device 5 is shown here, three or more (not shown) including the display device 7 may be installed.

主監視装置４、従監視装置５、表示装置７、及び集線装置用応答装置２１ａ〜２１ｎは、後述のネットワークＮを介して信号を伝送するため、それぞれが固有の識別情報ＩＤを持ち、その識別情報ＩＤにより各装置間で通信する。   Since the main monitoring device 4, the slave monitoring device 5, the display device 7, and the concentrator response devices 21a to 21n transmit signals via the network N described later, each has a unique identification information ID, and its identification Communication is performed between the devices based on the information ID.

主監視装置４と従監視装置５には、それぞれ受変電設備を構成する変圧器、遮断器、その他空調、照明関連の機器が接続され、主監視装置４と従監視装置５からはそれぞれの自己監視信号と接続された被監視対象機器の監視信号とが集線装置２ａ、２ｂへ出力されている。   The main monitoring device 4 and the sub-monitoring device 5 are connected to transformers, circuit breakers, and other air-conditioning and lighting-related devices constituting the power receiving / transforming equipment, respectively. The monitoring signal and the monitoring signal of the monitored device connected thereto are output to the line concentrators 2a and 2b.

集線装置２ａ〜２ｎは、ハブ、又はノードと呼ばれる伝送装置である。そして、各集線装置２ａ〜２ｎの通信ポートには、主監視装置４又は従監視装置５、又は表示装置７と、集線装置２ａ〜２ｎに対応する集線装置用応答装置２１ａ〜２１ｎが接続される。そして、これらの各集線装置２ａ〜２ｎの通信ポートに入出力される信号を主監視装置４から指定される応答要求により指定された機器・装置の間で、伝送路１を介して中継伝送する。   The concentrators 2a to 2n are transmission devices called hubs or nodes. The main monitoring device 4 or the secondary monitoring device 5 or the display device 7 and the concentrator response devices 21a to 21n corresponding to the concentrators 2a to 2n are connected to the communication ports of the concentrators 2a to 2n. . Then, the signals input / output to / from the communication ports of the respective concentrators 2a to 2n are relayed and transmitted via the transmission line 1 between the devices / devices designated by the response request designated by the main monitoring device 4. .

即ち、伝送路１と伝送路１によって接続される集線装置２ａ〜２ｎとは、監視信号を送受信する監視信号ネットワークＮを構成している。   That is, the transmission line 1 and the line concentrators 2a to 2n connected by the transmission line 1 constitute a monitoring signal network N that transmits and receives monitoring signals.

信号を中継伝送する通信手順は、ＬＡＮ（Lacal Area Network）で用いられるＣＤＭＡ（符号分割多元接続）方式とは異なり、トークンパッシング、ＩＰ（インターネットプロトコル）等により通信手順上は信号の衝突や消滅が無く、また送信元、送信先が識別情報ＩＤにより特定できるものが用いられる。本実施形態の故障分離方法では、この集線装置には、識別情報ＩＤが付与されたものでなく、単なるハブの様な信号を集合・分配する機能のみの機器の場合でも故障分離を可能としている。   Unlike the CDMA (Code Division Multiple Access) method used in LAN (Lacal Area Network), the communication procedure for relaying signals does not cause collision or disappearance of signals due to token passing, IP (Internet Protocol), etc. None, and a transmission source and a transmission destination that can be specified by identification information ID are used. In the fault isolation method according to the present embodiment, the concentrator is not provided with identification information ID, but enables fault isolation even in the case of a device only having a function of collecting and distributing signals such as a hub. .

図２は、集線装置用応答装置２１ａ〜２１ｎの内部構成を示す機能ブロック図である。集線装置用応答装置２１ａ〜２１ｎは、各集線装置２ａ、２ｎの自己点検監視を行った監視信号を各集線装置２ａ、２ｎとの間で入出力する機器である。通常、主監視装置４から自装置宛の応答要求を受信すると、自装置が接続されている集線装置が正常であると判断し、応答要求に対応して自分自身が健全なとき正常を示すヘルシーの応答信号を識別情報ＩＤと共に出力する。   FIG. 2 is a functional block diagram showing an internal configuration of the concentrator response devices 21a to 21n. The concentrator response devices 21a to 21n are devices that input and output the monitoring signals obtained by performing self-inspection monitoring of the concentrators 2a and 2n to and from the concentrators 2a and 2n. Normally, when a response request addressed to the own device is received from the main monitoring device 4, it is determined that the line concentrator to which the own device is connected is normal, and indicates a healthy state when the device itself is healthy in response to the response request. Is output together with the identification information ID.

この集線装置用応答装置２１ａ〜２１ｎからのヘルシーの応答信号は、集線装置用応答装置自身の自己点検データを含まない単なる受信確認のみのオウム返しの応答であっても構わない。   The healthy response signal from the concentrator response devices 21a to 21n may be a response of a simple parrot return that does not include self-check data of the concentrator response device itself.

主監視装置４は従監視装置５および表示装置７、集線装置用応答装置２１ａ〜２１ｎとの間で応答要求を行って、監視信号を収集する。各監視装置に接続された機器からの監視信号を判読して、機器の動作状態を細部に点検するか、または、各機器や各集線装置用応答装置からの応答の有無を監視することにより、どの機器が故障しているかの故障分離を行う。   The main monitoring device 4 makes a response request between the slave monitoring device 5 and the display device 7 and the concentrator response devices 21a to 21n, and collects monitoring signals. By reading the monitoring signal from the equipment connected to each monitoring device and checking the operating state of the equipment in detail, or by monitoring the presence or absence of a response from each device or each concentrator response device, Perform fault isolation to determine which equipment has failed.

以下、本実施形態の遠隔監視システムの故障分離に関わる動作処理を中心に説明する。   Hereinafter, the operation processing related to the fault isolation of the remote monitoring system of this embodiment will be mainly described.

主監視装置４は、従監視装置５と表示装置７と集線装置用応答装置２１ａ、２１ｂ、２１ｎにネットワークＮを介して応答要求を行う。主監視装置４は、各機器から識別情報ＩＤと共にヘルシーの応答信号を受信するとそれが正常と判断する。いずれかの機器から応答がない場合、従監視装置５又は表示装置７と集線装置用応答装置２１ａ、２１ｂ、２１ｎの応答可否の組み合わせによって集線装置２ａ、２ｂ、２ｎが異常、従監視装置５又は表示装置７の異常、集線装置用応答装置２１ａ、２１ｂ、２１ｎが異常かを判断して、表示装置７に異常を送信する。以上の処理を一定時間毎に行うことにより監視を行うものである。   The main monitoring device 4 sends a response request to the slave monitoring device 5, the display device 7, and the concentrator response devices 21a, 21b, and 21n via the network N. When the main monitoring device 4 receives the healthy response signal together with the identification information ID from each device, the main monitoring device 4 determines that it is normal. When there is no response from any of the devices, the concentrators 2a, 2b, 2n are abnormal due to the combination of the response of the subordinate monitoring device 5 or display device 7 and the concentrator response devices 21a, 21b, 21n. It is determined whether the display device 7 is abnormal or the concentrator response devices 21a, 21b, 21n are abnormal, and the abnormality is transmitted to the display device 7. Monitoring is performed by performing the above processing at regular intervals.

主監視装置４は、ネットワークＮを介して監視信号の入力及び出力機能を有する集線装置２ａに接続され、従監視装置５、表示装置７、集線装置用応答装置２１ｂ、２１ｎ、集線装置２ａ〜２ｎの故障分離を行う。   The main monitoring device 4 is connected to the line concentrator 2a having monitoring signal input and output functions via the network N, and the slave monitoring device 5, the display device 7, the line concentrator response devices 21b and 21n, and the line concentrators 2a to 2n.

図５では、ビル１００においてビルの施設を管理するための主監視装置４は、従監視装置５と表示装置７と集線装置２ａ〜２ｎと集線装置用応答装置２１ａ〜２１ｎを使用しているものとする。   In FIG. 5, the main monitoring device 4 for managing the building facilities in the building 100 uses the sub-monitoring device 5, the display device 7, the line concentrators 2a to 2n, and the line concentrator response devices 21a to 21n. And

従監視装置５は、ネットワークＮを介して応答信号の送受信に関わる通信インタフェースを行う応答処理部５０と、主監視装置５からの応答信号に対応する被監視対象機器からの応答信号を監視する応答監視部５１とを備える。集線装置用応答装置２１ａ〜２１ｎもネットワーク５を介して応答信号の送受信に関わる通信インタフェースを行う応答処理部９０を備える。表示装置７も同様のネットワーク５を介して応答信号の送受信に関わる通信インタフェースを行う応答処理部７０を備え、また主監視装置４の送受信部４６から異常を示す警報を受信した場合、警報を発報する警報発報部７１を備える。   The slave monitoring device 5 performs a response processing unit 50 that performs a communication interface related to transmission / reception of a response signal via the network N, and a response that monitors a response signal from the monitored device corresponding to the response signal from the main monitoring device 5. And a monitoring unit 51. The concentrator response devices 21 a to 21 n also include a response processing unit 90 that performs a communication interface related to transmission / reception of response signals via the network 5. The display device 7 also includes a response processing unit 70 that performs a communication interface related to transmission / reception of response signals via the same network 5, and issues an alarm when an alarm indicating abnormality is received from the transmission / reception unit 46 of the main monitoring device 4. An alarm issuing unit 71 for reporting is provided.

主監視装置４は、所定のタイミング、又は図示されない入力手段から監視応答を要求するコマンド等を入力されたタイミングに従監視装置５と集線装置用応答装置２１ｂに応答要求信号１１１を応答要求部４１から図５では示さないがネットワークＮを介して送信する。従監視装置５と集線装置用応答装置２１ｂとはこれに対して、それぞれ自身が正常である場合、ヘルシーである応答信号１１２を識別情報ＩＤと共に返信する。主監視装置４は、正常でヘルシーの応答信号を受信した場合はこの正常な応答があったことを応答有無格納部４２から応答要求部４１と応答処理部４０へと通知する監視信号１１３を送信する処理を一定時間毎に繰り返す。   The main monitoring device 4 sends a response request signal 111 to the monitoring device 5 and the concentrator response device 21b according to a predetermined timing or a timing when a command for requesting a monitoring response is input from an input means (not shown). From FIG. 5, although not shown in FIG. On the other hand, when the slave monitoring device 5 and the concentrator response device 21b are normal, they return a healthy response signal 112 together with the identification information ID. When the main monitoring device 4 receives a normal and healthy response signal, the main monitoring device 4 transmits a monitoring signal 113 for notifying the response requesting unit 41 and the response processing unit 40 that this normal response has been received. This process is repeated at regular intervals.

図６は従監視装置５に異常がある場合の応答信号の処理手順を説明する概念図である。   FIG. 6 is a conceptual diagram illustrating a response signal processing procedure when the slave monitoring device 5 has an abnormality.

図６において、従監視装置５に異常がある場合には従監視装置５からの応答信号１１２はなく集線装置用応答装置２１ｂからの応答信号が有ったことを通知する信号１１４が応答有無格納部４２から集線装置異常判定部４３へ出力される。そして、集線装置異常判定部４３は、上述の様に従監視装置５が異常と判断する故障分離を行う。そして、従監視装置５の異常を通知する信号１１７が送受信部４６へ送信され、その異常を通知する警報信号１１８としてネットワークＮを介して表示装置７へ通知され、警報発報部７１で従監視装置５の異常が発報（表示）される。   In FIG. 6, when there is an abnormality in the slave monitoring device 5, there is no response signal 112 from the slave monitoring device 5 but a signal 114 for notifying that there is a response signal from the concentrator response device 21 b is stored as a response presence / absence. The data is output from the unit 42 to the concentrator abnormality determination unit 43. And the concentrator abnormality determination part 43 performs the fault isolation | separation which the monitoring apparatus 5 judges as abnormal as above-mentioned. Then, a signal 117 for notifying the abnormality of the slave monitoring device 5 is transmitted to the transmission / reception unit 46 and notified to the display device 7 through the network N as an alarm signal 118 for notifying the abnormality. An abnormality of the device 5 is reported (displayed).

図７は集線装置２ｂに異常がある場合の応答信号の処理手順を説明する概念図である。   FIG. 7 is a conceptual diagram illustrating a response signal processing procedure when there is an abnormality in the concentrator 2b.

図７において、集線装置２ｂに異常がある場合には、従監視装置５からも集線装置用応答装置２１ｂの識別情報ＩＤを持つ応答信号１１２が受信されない。そして集線装置用応答装置２１ｂからの応答信号１１２がない異常を通知する信号１１５が応答有無格納部４２から集線装置異常判定部４３へ出力される。そして、集線装置異常判定部４３は、従監視装置５と集線装置用応答装置２１ｂの両方からの応答信号１１２がないことから集線装置２ｂが通信できず異常であると判定し、集線装置２ｂの異常を通知する信号１１７が送受信部４６へ送信される。そして、その異常を通知する警報信号１１８が送受信部４６からネットワークＮを介して表示装置７の警報発報部７１へ通知される。   In FIG. 7, when there is an abnormality in the concentrator 2 b, the response signal 112 having the identification information ID of the concentrator response device 21 b is not received from the slave monitoring device 5. Then, a signal 115 for notifying that there is no response signal 112 from the concentrator response device 21b is output from the response presence / absence storage unit 42 to the concentrator determination unit 43. Then, the concentrator abnormality determining unit 43 determines that the concentrator 2b cannot communicate because there is no response signal 112 from both the slave monitoring device 5 and the concentrator response device 21b, and the concentrator 2b A signal 117 for notifying abnormality is transmitted to the transmission / reception unit 46. Then, an alarm signal 118 notifying the abnormality is notified from the transmitting / receiving unit 46 to the alarm issuing unit 71 of the display device 7 via the network N.

図８は集線装置用応答装置２１ｂに異常がある場合の応答信号の処理手順を説明する概念図である。   FIG. 8 is a conceptual diagram for explaining a response signal processing procedure when there is an abnormality in the concentrator response device 21b.

図８において、集線装置用応答装置２１ｂに異常がある場合、従監視装置５からの応答信号１１２を受信したが集線装置用応答装置２１ｂからの応答信号１１２がないことを示す異常を通知する信号１１６が応答有無格納部４２から集線装置用応答装置異常判定部４５へ出力される。そして、集線装置用応答装置異常判定部４５は、集線装置用応答装置２ｂに異常があると判定して、その異常を通知する信号１１７が送受信部４６へ送信され、更にその異常を通知する警報信号１１８がネットワークＮを介して表示装置７の警報発報部７１へ通知される。   In FIG. 8, when there is an abnormality in the concentrator response device 21b, a signal notifying the abnormality indicating that the response signal 112 from the slave monitoring device 5 is received but there is no response signal 112 from the concentrator response device 21b. 116 is output from the response presence / absence storage unit 42 to the concentrator response device abnormality determination unit 45. Then, the concentrator response device abnormality determination unit 45 determines that there is an abnormality in the concentrator response device 2b, a signal 117 for notifying the abnormality is transmitted to the transmission / reception unit 46, and an alarm for notifying the abnormality. The signal 118 is notified to the alarm issue unit 71 of the display device 7 via the network N.

このように従監視装置５と集線装置用応答装置２１ｂからの応答信号の組み合わせによりどの構成が異常であるかを判定できる。主監視装置４は応答結果から異常の種類を判定し、異常判定信号１１７、表示装置７の警報発報部７１にその異常信号１１８を送信する。   In this way, it is possible to determine which configuration is abnormal based on the combination of the response signals from the monitoring device 5 and the concentrator response device 21b. The main monitoring device 4 determines the type of abnormality from the response result, and transmits the abnormality determination signal 117 and the abnormality signal 118 to the alarm notification unit 71 of the display device 7.

また、図６〜図８は、１台の従監視装置５の場合についての故障分離を説明したが、複数台の場合であっても、主監視装置４は、応答要求、および応答信号に付加される識別情報ＩＤにより各従監視装置について故障分離が可能である。   6 to 8 illustrate the fault isolation for the case of one slave monitoring device 5, but the main monitoring device 4 adds to the response request and response signal even in the case of multiple devices. Fault identification can be performed for each slave monitoring device by the identification information ID.

また、表示装置７については、従監視装置５の図示されない内蔵ディスプレイ、ランプ等の表示手段により表示装置７の異常の警報を発報する点が異なるが図６〜図８と同様の手順を実施すれば故障分離が可能である。また、図示されない予備の表示装置また、内蔵ディスプレイを備える従監視装置へ警報信号が送信され、そこで警報が発報される様にしてもよい。   Further, the display device 7 is different in that an alarm of abnormality of the display device 7 is issued by a display means such as a built-in display or a lamp (not shown) of the sub-monitoring device 5, but the same procedure as in FIGS. 6 to 8 is performed. Fault isolation is possible. Further, an alarm signal may be transmitted to a standby display device (not shown) or a slave monitoring device having a built-in display, and an alarm may be issued there.

以上述べた説明は、予め主監視装置４と従監視装置５が設定されている場合の動作説明例である。従監視装置５に、図５〜図８の主監視装置４に備えている応答処理部４０、応答要求部４１、応答有無格納部４２、集線装置異常判定部４３、監視・表示装置異常判定部４４、集線装置用応答異常判定部４５、送受信部４６、応答監視部４７の構成を備えていれば、前述の実施形態と同様の処理を従監視装置５で行うことができる。このように主監視装置４と、同様な機能部を備えている従監視装置５にあってはその設定は初期設定によるほか、所定の自己診断プログラムにより相互に選択切替が行われるものであってもよい。   The above-described explanation is an operation explanation example when the main monitoring device 4 and the slave monitoring device 5 are set in advance. The slave monitoring device 5 includes a response processing unit 40, a response request unit 41, a response presence / absence storage unit 42, a line concentrator abnormality determination unit 43, and a monitoring / display device abnormality determination unit provided in the main monitoring device 4 of FIGS. 44. If the configuration of the concentrator response abnormality determination unit 45, the transmission / reception unit 46, and the response monitoring unit 47 is provided, the slave monitoring device 5 can perform the same processing as in the above-described embodiment. As described above, in the main monitoring device 4 and the slave monitoring device 5 having the same function unit, the setting is not only made by the initial setting, but also by the predetermined self-diagnosis program, the selection switching is performed mutually. Also good.

以上述べた実施形態によれば、低コストのハブである集線装置２ａ〜２ｎを用い、従監視装置５及び又は表示装置７、集線装置２ａ〜２ｎ、集線装置用応答装置２１ａ〜２１ｎの故障分離が迅速にできる遠隔監視システム及びその故障分離方法を提供することができる。   According to the embodiment described above, the fault isolation of the secondary monitoring device 5 and / or the display device 7, the concentrators 2a to 2n, and the concentrator response devices 21a to 21n using the concentrators 2a to 2n which are low-cost hubs. It is possible to provide a remote monitoring system and a fault isolation method thereof that can be performed quickly.

図９は、前述の実施形態の変形である実施形態を説明するためのフローチャートを示すもので、前述の実施形態の図４では、主監視装置４は従監視装置５と集線装置用応答装置２ｂに同時に応答要求を行っている（Ｓ１）が、図９の変形例では従監視装置５及び又は表示装置７にのみ応答要求を行う（Ｓ１０）。   FIG. 9 is a flowchart for explaining an embodiment which is a modification of the above-described embodiment. In FIG. 4 of the above-described embodiment, the main monitoring device 4 is a slave monitoring device 5 and a concentrator response device 2b. At the same time, a response request is made (S1), but in the modified example of FIG. 9, a response request is made only to the slave monitoring device 5 and / or the display device 7 (S10).

そして、従視装置５及び又は、表示装置７からの応答信号があるかを判断し（Ｓ１１）、ステップＳ１１において応答信号が無い場合に集線装置用応答装置２１ａ〜２１ｎに対して応答要求を行い（Ｓ１２）、その後集線装置用応答装置２１ａ〜２１ｎから応答信号があるかどうかを判断し（Ｓ１３）、集線装置用応答装置２１ａ〜２１ｎから応答要求が無い場合、集線装置２ａ〜２ｎが異常とする（Ｓ１５）。ステップＳ１３において、集線装置用応答装置２１ａ〜２１ｎから応答信号があると判断すると、従監視装置５及び又は表示装置７の異常とする。   Then, it is determined whether there is a response signal from the slave device 5 and / or the display device 7 (S11), and if there is no response signal in step S11, a response request is made to the concentrator response devices 21a-21n. (S12) After that, it is determined whether or not there is a response signal from the concentrator response devices 21a to 21n (S13). If there is no response request from the concentrator response devices 21a to 21n, the concentrators 2a to 2n are abnormal. (S15). If it is determined in step S13 that there is a response signal from the concentrator response devices 21a to 21n, the slave monitoring device 5 and / or the display device 7 are regarded as abnormal.

集線装置用応答装置２１ａ〜２１ｎは、本来集線装置が動作しているか否かを確認するための装置であって、前述の様に単純なオウム返しの機能で済ませる場合は部品数が少なく故障やエラーの発生が少ないので、故障分離の対象から除外しても支障は少ない。   The concentrator response devices 21a to 21n are devices for confirming whether or not the concentrator is operating. When the simple parrot return function can be used as described above, the number of parts is small, Since there are few errors, there is little trouble even if it is excluded from the target of fault isolation.

変形例の実施形態は、集線装置用応答装置２１ａ、２１ｂ、２１ｎの監視を省略することにより異常発生時には、改めて集線装置用応答装置２１ｂに応答要求（Ｓ１２）を行うため前述の実施形態よりも異常機器特定に時間がかかるが、正常時は応答要求の数を半分に減少させることができるのでネットワークＮに対する伝送量を減少させる効果がある。   In the embodiment of the modified example, when the abnormality occurs by omitting the monitoring of the concentrator response devices 21a, 21b, and 21n, a response request (S12) is made again to the concentrator response device 21b. Although it takes time to identify an abnormal device, the number of response requests can be reduced to half when normal, so there is an effect of reducing the amount of transmission to the network N.

また、上記の故障分離方法と、変形例とを切り替える様にして使用してもよい。例えば、前者の方法で監視をするうち、主監視装置４の応答処理部４０が、送受信部４６におけるトラフィックを監視し所定のトラフィックを超える場合、変形例に故障分離モードを変更する様に切り替える様にしてもよい。さらに、主監視装置４の図示されない入力手段からオペレータによって入力されるコマンドによって切り替える様にしてもよい。   Moreover, you may use so that said fault isolation | separation method and a modification may be switched. For example, while monitoring by the former method, when the response processing unit 40 of the main monitoring device 4 monitors the traffic in the transmission / reception unit 46 and exceeds the predetermined traffic, it is switched to change the failure isolation mode to the modified example. It may be. Furthermore, it may be switched by a command input by an operator from an input means (not shown) of the main monitoring device 4.

また、前述した実施形態の表示装置７は、従監視装置５と同様な機能を備えると共に、警報表示手段を含むものであってもよく、その警報表示手段は主監視装置４における故障分離手段が判定した異常を通知する警報信号をネットワークＮを介して警報表示手段へ送信し、その警報信号を受信した場合、その異常の警報を発報するようにしてもよい。   In addition, the display device 7 of the above-described embodiment may have a function similar to that of the slave monitoring device 5 and may include an alarm display unit. The alarm display unit may be a failure separation unit in the main monitoring device 4. An alarm signal for notifying the determined abnormality may be transmitted to the alarm display means via the network N, and when the alarm signal is received, an alarm for the abnormality may be issued.

以上説明した如く、本発明の実施形態の遠隔監視システムでは、集線装置２ａ〜２ｎに通信上の識別情報ＩＤを用いない場合であっても集線装置を含めて遠隔監視システムを構成する装置、機器の故障分離が可能なため、コストを抑えることが可能である。   As described above, in the remote monitoring system according to the embodiment of the present invention, the devices and devices constituting the remote monitoring system including the line concentrator even when the communication identification information ID is not used for the line concentrators 2a to 2n. Therefore, it is possible to reduce costs.
