Description

この発明は、船内の監視制御室側に設けられた監視制御装置により船内の被監視制御機器を監視制御する船内監視制御システムに関するものである。 The present invention relates to an in-board monitoring control system for monitoring and controlling a monitored control device in a ship by a monitoring control device provided on the monitoring control room side in the ship.

船舶において、近年は、船体内の各所に存在する機関やタンク等の被監視制御機器側の状態をデ−タとして収集し、船橋等に在る操船室や制御室等の監視制御室側へ伝送し、遠隔にて、例えば運転時の発電機温度、燃料圧力などの監視や、例えば燃料ポンプ、冷却ファンなどの制御を行う場合、船体内の各所に点在する被監視制御機器に取り付けられた例えば温度、圧力などの各種センサ類や例えば調節弁、冷却弁などのアクチュエ−タ類等の被監視制御機器と前記監視制御室側の監視制御装置との間でデ−タ伝送を行うための専用の伝送ケ−ブルを敷設して船内ＬＡＮ等の専用の船内情報ネットワ−クを使った船内デ−タ伝送システムが構築されており、この船内デ−タ伝送システムを介して船内の各種情報の伝送が行われている。 In recent years, in the ship, the state of the monitored control equipment such as engines and tanks existing in various places in the hull is collected as data and sent to the monitoring control room such as the maneuvering room and control room on the bridge. When remotely monitoring, for example, the generator temperature and fuel pressure during operation, or controlling the fuel pump, cooling fan, etc., for example, it is attached to monitored control devices scattered throughout the ship. To transmit data between monitored sensors such as various sensors such as temperature and pressure, and actuators such as control valves and cooling valves, and the monitoring control device on the monitoring control room side. An inboard data transmission system using a dedicated inboard information network such as an inboard LAN has been constructed by laying a dedicated transmission cable of Information is being transmitted.

この種の従来の船内監視制御システムの事例としては、例えば、特開平７−２７７２８３号公報（特許文献１）に記載のものがある。 An example of this type of conventional shipboard monitoring and control system is disclosed in, for example, Japanese Patent Laid-Open No. 7-277283 (Patent Document 1).

一方、既存の船舶、特に古い船舶には、前述のような船内監視制御システムが採用されていない場合が多い。 On the other hand, existing ships, particularly old ships, often do not employ the above-described inboard monitoring and control system .

特開平７−２７７２８３号公報（図１〜図４及びその説明）Japanese Patent Laid-Open No. 7-277283 (FIGS. 1-4 and description thereof)

前述の船内監視制御システムが採用されていない既存の船舶に、前述のような前記被監視制御機器と前記監視制御室側の監視制御装置との間でデ−タ伝送を行うための専用の伝送ケ−ブルを敷設して船内ＬＡＮ等の専用の船内情報ネットワ−クを使った船内デ−タ伝送システムを構築する場合、船体内では、防水上、壁や天井に伝送ケ−ブル貫通口を設けることができる部位が限られており、特に大型の船舶では、迂回のために相当長い伝送ケ−ブルが必要となったり、伝送ケ−ブル自体を設置できない場合もあるなど、伝送ケ−ブルを新たに設置するのに手間がかかり、また、その設置費用が高くなってしまう。 Dedicated transmission for data transmission between the monitored control device as described above and the monitoring control device on the monitoring control room side to an existing ship that does not employ the inboard monitoring control system. When constructing an inboard data transmission system using a dedicated inboard information network such as an inboard LAN by laying the cable, the transmission cable through-hole is provided on the wall and ceiling in the hull. The parts that can be installed are limited, especially in large ships, a transmission cable that may require a considerably long transmission cable for detouring or the transmission cable itself may not be installed. It takes time and effort to install a new device, and the installation cost becomes high.

また、船内監視制御システムを採用し前記被監視制御機器と監視制御装置との間でデ−タ伝送を行うための専用の伝送ケ−ブルが敷設されている船舶においては、荒天などによる積荷の揺れや移動、船体の軋みなどによる伝送ケ−ブルの断線等による伝送障害が万一発生した場合、通常は船内デ−タ伝送システムの専門の保守要員は乗船しておらず、しかも船内情報ネットワ−クを使った船内デ−タ伝送システムは専門性が高いので、その復旧が困難な場合が生じ、デ−タ伝送が長時間できない状態が継続する場合が生じ得る。 In addition, in a ship that employs an inboard supervisory control system and is equipped with a dedicated transmission cable for data transmission between the monitored control device and the supervisory control device, cargoes caused by stormy weather etc. In the unlikely event that a transmission failure occurs due to disconnection of the transmission cable due to shaking, movement, or stagnation of the hull, there are usually no onboard data transmission system specialized maintenance personnel on board, and the inboard information network -Since the in-board data transmission system using the hook is highly specialized, it may be difficult to restore the data, and there may be a case where the data transmission cannot continue for a long time.

従って、デ−タ伝送による船内監視制御システムを採用する場合、設置が容易でありしかも設置費用が低廉である船内監視制御システムとすることが望まれる。また、デ−タ伝送が長時間できない状態が生じないようにすることが望まれる。 Therefore, when an inboard monitoring and control system using data transmission is adopted, it is desired to provide an inboard monitoring and control system that is easy to install and inexpensive to install. It is also desirable to prevent a situation where data transmission cannot be performed for a long time.

この発明の実施の形態１は、前述のように、船内の監視制御室側に監視制御装置１１およびこの監視制御装置１１に接続された監視制御側電力線通信装置１２を有する親局１を設けると共に、船内の被監視制御機器５ａ〜５ｎの側に前記被監視制御機器５ａ〜５ｎの船内信号入出力装置２１およびこの船内信号入出力装置２１に接続された被監視制御側電力線通信装置２２を有する子局２ａ〜２ｎを設け、船内の各被監視制御機器５ａ〜５ｎの状態を、前記被監視制御側電力線通信装置２２と船内電力線３と前記監視制御側電力線通信装置１２とを介して、前記監視制御装置１１により監視し、船内の各被監視制御機器５ａ〜５ｎを、前記監視制御側電力線通信装置１２と前記船内電力線３と前記被監視制御側電力線通信装置とを介して、前記監視制御装置１１により制御するので、船内監視制御方式が採用されていない既存の船舶に前記被監視制御機器５ａ〜５ｎと前記監視制御装置１１との間でデ−タ伝送を行うための専用の伝送ケ−ブルを敷設して船内ＬＡＮ等の専用の船内情報ネットワ−クを使った船内デ−タ伝送システムを構築する従来の場合のように、船体内であるが故に、防水上、壁や天井に伝送ケ−ブル貫通口を設けることができる部位が制限され、特に大型の船舶では、迂回のために相当長い伝送ケ−ブルが必要となったり、伝送ケ−ブル自体を設置できない場合もあるなど、伝送ケ−ブルを新たに設置するのに手間がかかり、また、その設置費用が高くなってしまうというようなことがなくなり、設置が容易でしかも設置費用が低廉となる。 In the first embodiment of the present invention, as described above, the master station 1 having the monitoring control device 11 and the monitoring control side power line communication device 12 connected to the monitoring control device 11 is provided on the monitoring control room side in the ship. The inboard signal input / output device 21 of the monitored control devices 5a to 5n and the monitored control side power line communication device 22 connected to the inboard signal input / output device 21 are provided on the monitored control devices 5a to 5n in the ship. The slave stations 2a to 2n are provided, and the state of each of the monitored control devices 5a to 5n in the ship is changed through the monitored control side power line communication device 22, the inboard power line 3 and the monitoring control side power line communication device 12 Monitored by the monitoring control device 11, the monitored control devices 5 a to 5 n in the ship are connected to the front via the monitoring control side power line communication device 12, the inboard power line 3, and the monitored control side power line communication device. Since the control is performed by the supervisory control device 11, a dedicated data transmission is performed between the monitored control devices 5a to 5n and the supervisory control device 11 for an existing ship that does not employ the inboard supervisory control method. As in the conventional case of constructing an inboard data transmission system using a dedicated inboard information network such as an inboard LAN by laying a transmission cable, because it is inside the ship's body, it is waterproof, The part where the transmission cable through-hole can be provided on the ceiling is limited. Especially in large ships, a considerably long transmission cable may be required for detouring, or the transmission cable itself cannot be installed. For example, it takes time to newly install a transmission cable, and the installation cost is not increased, so that the installation is easy and the installation cost is low.

また、船内電力線３は、デ−タ伝送を行うための専用の伝送ケ−ブルより大径で強度が大きいので断線し難く、また、例えば過負荷などによるノ−ヒュ−ズブレ−カのＯＦＦ動作などにより船内電力線３の或る区間で万一停電が生じても、船内の不点灯照明や不動作電力機器の範囲から停電区間を容易に把握できると共に、その復電も、船内情報ネットワ−クを使った船内デ−タ伝送システムのような専門性の高い要員でなくても容易に可能であるので、デ−タ伝送を行うための専用の伝送ケ−ブルを敷設して船内ＬＡＮ等の専用の船内情報ネットワ−クを使った船内デ−タ伝送システムを構築する従来の場合のように伝送障害が万一発生した場合に船内デ−タ伝送システムの専門の保守要員が乗船していないことによりデ−タ伝送が長時間できない状態が継続する場合が生じるようなことがなくなり、信頼性の高い船内監視制御システムを実現できる。 Further, the inboard power line 3 is larger in diameter and stronger than a dedicated transmission cable for data transmission, so that it is difficult to disconnect, and for example, the fuse breaker OFF operation due to overload or the like. Even if a power outage occurs in a certain section of the inboard power line 3, the power outage section can be easily grasped from the range of non-lighting lighting and non-operating power equipment in the ship, and the power recovery is also performed in the inboard information network. Because it is possible even without highly specialized personnel such as an inboard data transmission system using an inboard, a dedicated transmission cable for performing data transmission is laid and an inboard LAN etc. Constructing an inboard data transmission system using a dedicated inboard information network In the unlikely event that a transmission failure occurs, no specialized maintenance personnel for the inboard data transmission system are on board. Data transmission for a long time When the state that can not continues prevents such results, it is possible to realize a highly reliable inboard monitoring and control system.

しかしながら、前述の発明が解決しようとする課題やこの発明の実施の形態１において詳述したように、伝送ケ−ブルに断線等による伝送障害が生じた場合、前記前記船内被監視制御機器５ａ〜５ｎの各種センサ類４ａ〜４ｎから前記船内親局１内の前記船内監視制御装置１１への計測デ−タ（前記船内被監視制御機器５ａ〜５ｎの状態信号）や、前記船内親局１内の前記船内監視制御装置１１から前記船内被監視制御機器５ａ〜５ｎの各種アクチュエ−タ類６ａ〜６ｎへの制御信号の伝送ができなくなり、場合によっては、伝送障害の復旧までに長時間かかる場合がある。 However, as described in detail in the problem to be solved by the above-described invention and the first embodiment of the present invention, when a transmission failure occurs due to disconnection or the like in the transmission cable, the inboard monitored control device 5a to Measurement data (status signals of the inboard monitored control devices 5a to 5n) from the various sensors 4a to 4n to the inboard monitoring control device 11 in the inboard main station 1, and the inboard main station 1 The control signal cannot be transmitted from the inboard monitoring and control device 11 to the various actuators 6a to 6n of the inboard monitored control devices 5a to 5n, and in some cases, it takes a long time to recover from the transmission failure. There is.

このようなことを回避するために、この発明の実施の形態２においては、前記船内被監視制御機器５ａ〜５ｎと前記監視制御室側の船内監視制御装置１１との間でデ−タ伝送を行うための専用の伝送ケ−ブルを敷設して船内ＬＡＮ等の専用の船内情報ネットワ−ク７を使った船内デ−タ伝送システムが構築されている船舶に、前述のこの発明の実施の形態１の船内監視制御方式を併用し、船内情報ネットワ−ク７に伝送障害が発生した場合には、前述のこの発明の実施の形態１の船内監視制御方式により、前記船内被監視制御機器５ａ〜５ｎと前記監視制御室側の船内監視制御装置１１との間で前記計測デ−タ（前記船内被監視制御機器５ａ〜５ｎの状態信号）や前記制御信号の伝送を行い、バックアップ動作するようにしてある。 In order to avoid such a situation, in Embodiment 2 of the present invention, data transmission is performed between the in-board monitored control devices 5a to 5n and the in-board monitoring control device 11 on the monitoring control room side. The above-described embodiment of the present invention is applied to a ship in which an inboard data transmission system using an inboard information network 7 such as an inboard LAN is constructed by laying a dedicated transmission cable for performing the above.

前述のように、通常は、前記船内被監視制御機器５ａ〜５ｎの各種センサ類４ａ〜４ｎから前記船内親局１内の前記船内監視制御装置１１への計測デ−タ（前記船内被監視制御機器５ａ〜５ｎの状態信号）や、前記船内親局１内の前記船内監視制御装置１１から前記船内被監視制御機器５ａ〜５ｎの各種アクチュエ−タ類６ａ〜６ｎへの制御信号は、インサ−ネット等の伝送方式により前記船内情報ネットワ−ク７を介して伝送されている。 As described above, usually, measurement data from the various sensors 4a to 4n of the inboard monitoring control devices 5a to 5n to the inboard monitoring control device 11 in the inboard master station 1 (the inboard monitoring control). Status signals of the devices 5a to 5n) and control signals from the inboard monitoring control device 11 in the inboard master station 1 to the various actuators 6a to 6n of the inboard monitored control devices 5a to 5n are The information is transmitted via the inboard information network 7 by a transmission method such as a network.

この状態で、前記船内情報ネットワ−ク７の伝送ケ−ブルの断線等で伝送障害が発生した場合は、前記船内親局１内の前記船内監視制御装置１１から出力されている状態問合わせパケット信号に対して、前記船内子局２ａ〜２ｎ内の船内信号入出力装置２１からの応答信号が前記伝送障害に起因して届かないことにより、前記船内親局１側では、前記船内子局２ａ〜２ｎ内のうちのどの船内子局との伝送路に障害が発生したか把握できる。 In this state, when a transmission failure occurs due to a disconnection of the transmission cable of the inboard information network 7, a state inquiry packet output from the inboard monitoring control device 11 in the inboard master station 1 In response to the signal, the response signal from the inboard signal input / output device 21 in the inboard child stations 2a to 2n does not reach due to the transmission failure, so that the inboard child station 1a has the inboard child station 2a. It is possible to grasp which of the inboard child stations in .about.2n has a failure in the transmission path.

そこで、前記船内親局１は、伝送できなくなっている船内子局２ａ〜２ｎに対して、前記監視制御側船内電力線通信装置１２→前記船内電力線３→前記被監視制御側船内電力線通信装置２２の伝送ル−トで、今後は前記船内情報ネットワ−ク７による伝送から、前記監視制御側船内電力線通信装置１２→前記船内電力線３→前記被監視制御側船内電力線通信装置２２の伝送ル−トの伝送へ切り替える旨の信号を送信し、その信号を、前記監視制御側船内電力線通信装置１２→前記船内電力線３→前記被監視制御側船内電力線通信装置２２の伝送ル−トで受信した船内子局２ａ〜２ｎは、前記船内情報ネットワ−ク７による伝送から、前記監視制御側船内電力線通信装置１２→前記船内電力線３→前記被監視制御側船内電力線通信装置２２の伝送ル−トの伝送へ切り替えることができる。 Therefore, the inboard master station 1 is connected to the inboard slave stations 2a to 2n that are unable to transmit the monitoring control side inboard power line communication device 12 → the inboard power line 3 → the monitored control side inboard power line communication device 22. From now on, the transmission route of the supervisory control side inboard power line communication device 12 → the inboard power line 3 → the monitored control side inboard power line communication device 22 from the transmission by the inboard information network 7 will be described. An inboard child station that transmits a signal for switching to transmission and that is received by the transmission route of the supervisory control side inboard power line communication device 12 → the inboard power line 3 → the monitored control side inboard power line communication device 22 2a to 2n are transmitted from the inboard information network 7 to the transmission from the supervisory control side inboard power line communication device 12 to the inboard power line 3 to the monitored control side inboard power line communication device 22. Le - can be switched to preparative transmission.

この場合、前記監視制御側船内電力線通信装置１２→前記船内電力線３→前記被監視制御側船内電力線通信装置２２の伝送ル−トの伝送はバックアップであるので、前記船内情報ネットワ−ク７の伝送障害が復旧した場合は、前記船内親局１から対象となる前記船内子局２ａ〜２ｎへ、前記監視制御側船内電力線通信装置１２→前記船内電力線３→前記被監視制御側船内電力線通信装置２２の伝送ル−トの伝送から前記船内情報ネットワ−ク７による伝送へ切り替える旨の信号を送信することにより、その信号を、前記監視制御側船内電力線通信装置１２→前記船内電力線３→前記被監視制御側船内電力線通信装置２２の伝送ル−トで受信した船内子局２ａ〜２ｎは、前記監視制御側船内電力線通信装置１２→前記船内電力線３→前記被監視制御側船内電力線通信装置２２の伝送ル−トの伝送から、前記船内情報ネットワ−ク７による伝送へ切り替え、通常の前記船内情報ネットワ−ク７による伝送へ復旧することができる。 In this case, since the transmission route transmission of the supervisory control side inboard power line communication device 12 → the inboard power line 3 → the monitored control side inboard power line communication device 22 is a backup, the transmission of the inboard information network 7 is performed. When the fault is recovered, the inboard power station communication device 12 → the inboard power line 3 → the inboard power line communication device 22 to be monitored is transferred from the inboard master station 1 to the target inboard slave stations 2a to 2n. By transmitting a signal to switch from transmission of the transmission route to transmission by the inboard information network 7, the signal is sent to the supervisory control side inboard power line communication device 12 → the inboard power line 3 → the monitored target. The inboard slave stations 2a to 2n received by the transmission route of the control side inboard power line communication device 22 are connected to the supervisory control side inboard power line communication device 12 → the inboard power line 3 → the monitored object. From Preparative transmission, the inboard information networks - - transmission le of your side inboard power line communication apparatus 22 switches to the transmission by click 7, normally the ship information networks - can be restored to the transmission by the click 7.

このように、この発明の実施の形態２は、船内の監視制御室側に設けられた船内監視制御装置１１により船内情報ネットワ−ク７を介して船内の被監視制御機器５ａ〜５ｎを監視制御する船内監視制御方式において、前記監視制御室側に前記船内監視制御装置１１に接続された監視制御側船内電力線通信装置１２を設けると共に、前記船内被監視制御機器５ａ〜５ｎの側に前記船内被監視制御機器５ａ〜５ｎの船内信号入出力装置２１に接続された被監視制御側船内電力線通信装置２２を設け、船内の各被監視制御機器５ａ〜５ｎの状態を、必要に応じて、前記被監視制御側船内電力線通信装置２２と船内電力線３と前記監視制御側船内電力線通信装置１２とを介して、前記船内監視制御装置１１により監視し、船内の各被監視制御機器５ａ〜５ｎを、必要に応じて、前記監視制御側船内電力線通信装置１２と前記船内電力線３と前記被監視制御側船内電力線通信装置２２とを介して、前記船内監視制御装置１１により制御する船内監視制御システムとしたので、船内監視制御方式を採用し前記船内被監視制御機器５ａ〜５ｎと船内監視制御装置１１との間で船内情報ネットワ−ク７を介してデ−タ伝送を行うための専用の伝送ケ−ブルが敷設されている船舶においては、例えば荒天などによる積荷の揺れや移動、船体の軋みなどによる伝送ケ−ブルの断線等による伝送障害が万一発生した場合、通常は船内デ−タ伝送システムの専門の保守要員は乗船しておらず、しかも船内情報ネットワ−クを使った船内デ−タ伝送システムは専門性が高いので、その復旧が困難な場合が生じ、デ−タ伝送が長時間できない状態が継続する場合が生じ得るが、そのようなことがなくなり、信頼性の高い船内監視制御システムを実現できる。 As described above, in the second embodiment of the present invention, the monitored control devices 5a to 5n in the ship are monitored and controlled via the inboard information network 7 by the inboard monitoring control apparatus 11 provided on the monitoring control room side in the ship. In the inboard supervisory control system, the supervisory control side inboard power line communication device 12 connected to the inboard supervisory control device 11 is provided on the supervisory control room side, and the inboard supervisory control devices 5a to 5n are provided with the inboard cover. A monitored and controlled inboard power line communication device 22 connected to the inboard signal input / output device 21 of the monitoring and control equipment 5a to 5n is provided, and the status of each of the monitored and controlled equipment 5a to 5n in the ship is changed as necessary. Monitoring is performed by the inboard monitoring control device 11 via the monitoring control side inboard power line communication device 22, the inboard power line 3, and the monitoring control side inboard power line communication device 12, and each monitored control device 5a in the ship is monitored. The 5n, if necessary, said monitoring control side inboard power line communication apparatus 12 and the inboard power line 3 via the monitored control side inboard power line communication apparatus 22, inboard monitoring control for controlling by said inboard monitoring control device 11 Since it is a system , a dedicated monitoring system is adopted for data transmission between the in-board monitored control devices 5a to 5n and the in-board monitoring control device 11 via the in-board information network 7. In ships where transmission cables are laid, for example, if a transmission failure occurs due to transmission cable breakage due to swaying or moving of the load due to stormy weather, stagnation of the hull, etc. No special maintenance personnel for the data transmission system are on board, and the inboard data transmission system using the inboard information network is highly specialized. - If the state of data transmission can not be a long period of time to continue may occur, but there is no such thing, it is possible to realize a highly reliable inboard monitoring and control system.
