Description

本考案は、船舶における機関区画給電システムに関する。   The present invention relates to an engine compartment power supply system in a ship.

従来、船舶における機関区画給電システムは、図3に示すように、機関区画に装備された動力機器の遠隔始動・遠隔停止及び遠隔状態監視信号などを各機器毎に専用のケーブルを用いてアナログ信号として機関制御盤兼監視盤へ伝送していた。このため、各デッキ毎に最短長となる位置に多芯線接続箱を設け多芯線化し、電線本数を減らす省配線化し伝送していた。   Conventionally, as shown in FIG. 3, the engine compartment power supply system in a ship uses a dedicated cable for each device to perform remote start / stop and remote status monitoring signals of power equipment installed in the engine compartment. It was transmitted to the engine control panel and monitoring panel. For this reason, a multi-core wire connection box is provided at the position where the shortest length is provided for each deck to make multi-core wires, reducing the number of wires and reducing the transmission.

図3は、従来の船舶における機関区画給電システムの概略を示す図であり、図3中、符号100は、機関室、101、102,103は、各デッキ、104は、機関室デッキ101上に配置されるNo.1集合始動器盤、105は、同主配電盤(発電機盤およびAC440V給電盤)、106は、No.2集合始動器盤、107は、機関制御盤兼監視盤である。また、108は、前記デッキ102上に配置されたポンプおよび電動機であり、109は、同発停箱、110は、同ポンプおよび電動機、111は、同発停箱、112は、多芯線接続箱であり、113、114、115は、それぞれ前記多芯線接続箱112に接続されるセンサである。   FIG. 3 is a diagram showing an outline of an engine compartment power supply system in a conventional ship. In FIG. 3, reference numeral 100 denotes an engine room, 101, 102, and 103 each deck, and 104 on the engine room deck 101. No. to be arranged 1 collective starter panel, 105 is the main switchboard (generator panel and AC440V power supply panel), 106 is No. A two-set starter panel 107 is an engine control panel / monitoring panel. Further, 108 is a pump and an electric motor arranged on the deck 102, 109 is the same stop / stop box, 110 is the same pump and electric motor, 111 is the same start / stop box, and 112 is a multi-core wire connection box. 113, 114 and 115 are sensors connected to the multi-core connection box 112, respectively.

また、116は、前記デッキ103上に配置されたポンプおよび電動機であり、117は、同発停箱、118は、同ポンプおよび電動機、119は、同発停箱、120は、多芯線接続箱であり、121、122、123は、それぞれ前記多芯線接続箱120に接続されるセンサである。また、濃実線で示されるのが、AC440V給電線であり、波線で示されるのが、遠隔発停止電線、点線で示されるのが、計装信号線(アナログ信号)である。   Further, 116 is a pump and an electric motor arranged on the deck 103, 117 is the same starting and stopping box, 118 is the same pump and electric motor, 119 is the same starting and stopping box, and 120 is a multi-core connection box. Reference numerals 121, 122, and 123 denote sensors connected to the multi-core connection box 120, respectively. In addition, a solid line indicates an AC440V power supply line, a dashed line indicates a remote stop electric wire, and a dotted line indicates an instrumentation signal line (analog signal).

そこで、このような船舶内の信号伝送に多芯線化を図り、省配線化は可能となったが、アナログ信号伝送はそのままであるため、結線作業や電線布設占有面積においては、多芯線化を図る以前と変わることはなく、しかも電線長が長いので現場工数が多く掛かってしまうという問題があった。そこで、少なくとも、この種の機関区画に装備された動力機器の遠隔始動・遠隔停止及び遠隔状態監視信号の伝送に関し、デジタル化を図り、また、電力線を通じて伝送するものとしては、いわゆるPLCを用いた、例えば、特開2004−56197号公報等に開示のものが知られている。   Therefore, multi-core wires are used for signal transmission in such ships, and wiring can be saved, but analog signal transmission remains as it is. There was no change from before it was planned, and there was a problem that it took a lot of man-hours on site because the wire length was long. Therefore, at least for the remote start / stop of the power equipment installed in this type of engine compartment and the transmission of the remote condition monitoring signal, digitization is attempted, and so-called PLC is used as the transmission through the power line. For example, what is disclosed in Japanese Patent Application Laid-Open No. 2004-56197 is known.

特開2004−56197号公報に開示ものは、発明名称「電力線通信システム」に係り、「電力線を介して通信を行う電子装置群の通信信号が、電力線を介して電力の供給のみを受ける電子装置群の動作に影響を与えることを防止し、更に、通信信号を確実に送信先へ伝送可能な電力線通信システムを提供すること(同公報明細書段落番号0005参照)」を目的として、「接続した第1の接続領域と、電力線を介して電力の供給のみを受ける電子装置群を接続した第2の接続領域とに分割する。そして、第1,2の接続領域間に具備された信号遮断手段によって、第1の接続領域に接続した電子装置群の通信信号を遮断する」構成とすることにより(同公報明細書段落番号0006参照)、「電力線を介して電力の供給のみを受ける電子装置群が、電力線を介して互いに通信を行う電子装置群の通信経路上に混在しない上、電力線を介して互いに通信を行う電子装置群の通信信号が、第1の接続領域内にて遮断されるため、電力線を介して互いに通信を行う電子装置群の通信信号が、電力線を介して電力の供給のみを受ける電子装置群の動作に影響を与えることを防止できる(同公報明細書段落番号0007参照)」とするものである。   Japanese Patent Laid-Open No. 2004-56197 relates to an invention name “power line communication system”, “an electronic device in which a communication signal of an electronic device group that performs communication via a power line is only supplied with power via the power line” For the purpose of providing a power line communication system capable of preventing the influence of the operation of the group and further reliably transmitting a communication signal to the transmission destination (see paragraph number 0005 of the publication) The first connection area is divided into a second connection area to which an electronic device group that receives only power supply via a power line is connected, and signal blocking means provided between the first and second connection areas. Is configured to block the communication signal of the electronic device group connected to the first connection region (see paragraph number 0006 of the same gazette specification), so that the “electron receiving only power supply via the power line” The device group is not mixed on the communication path of the electronic device group that communicates with each other via the power line, and the communication signal of the electronic device group that communicates with each other via the power line is blocked in the first connection region. Therefore, it is possible to prevent the communication signals of the electronic device groups that communicate with each other via the power line from affecting the operation of the electronic device group that receives only the supply of power via the power line (paragraph number 0007 of the publication). Reference) ”.

このように電力線通信(PLC)は、何ら新しいものではないが、しかし、上述するように、これを船舶船内の機関区画に装備された動力機器の遠隔始動・遠隔停止や遠隔状態監視信号等の各機器の制御や監視の信号伝送に応用しようとするとき、船舶では、上述するように、AC440V給電を行っているため、家庭内のAC100V耐用ののものを持ち込むことはできず、また、特開2004−56197号公報に開示のもののように自動車制御に使用するものをそのまま使用することはできない。
特開2004−56197号公報
In this way, power line communication (PLC) is not new, but as described above, it is used for remote start / stop of power equipment and remote condition monitoring signals for power equipment installed in the engine compartment in the ship. When trying to apply to control and monitoring signal transmission of each device, as described above, since the ship is powered by AC440V, it is not possible to bring in an AC100V-resistant one in the home. Those used for automobile control such as those disclosed in Japanese Unexamined Patent Publication No. 2004-56197 cannot be used as they are.

そこで、電線布設占有面積を減少させ結線作業を軽減可能な区画別給電方式及ぴ集配線システムを提供し、さらに、主配電盤のコンパクト化を図ることを目的とする。   Accordingly, it is an object of the present invention to provide a section-by-section power supply method and a collection and wiring system that can reduce the wiring installation occupation area and reduce the wiring work, and further aim to make the main switchboard compact.

上記目的を達成するために、本願請求項1に係る考案は、船舶内の機関制御・監視を行う船舶における機関区画給電システムにおいて、船舶機関室近傍に配置される機関制御盤兼監視盤に接続され、LAN電線にて伝送可能なI/Oユニットを備える給電盤兼集合始動器盤と、他のデッキ上に配置される前記ポンプおよび電動機に接続され、LAN電線にて伝送可能なI/Oユニットを備える第一の給電盤兼集合始動器盤とからなることを特徴とする。   In order to achieve the above object, the invention according to claim 1 of the present application is connected to an engine control panel / monitoring panel disposed in the vicinity of a ship engine room in an engine compartment power supply system for a ship that performs engine control / monitoring in the ship. I / O that is connected to a power supply panel / collective starter panel having an I / O unit that can be transmitted by a LAN wire, and the pump and motor disposed on another deck, and that can be transmitted by a LAN wire. It is characterized by comprising a first power supply panel and collective starter panel provided with a unit.

また、本願請求項2に係る考案は、前記請求項1に係る船舶における機関区画給電システムにおいて、前記I/Oユニットは、LAN電線にて伝送可能なI/Oユニットに替え、AC440V対応のPLCを備え、船舶内のAC440V動力ケーブルにて伝送可能なI/Oユニットであることを特徴とする。   Further, the invention according to claim 2 of the present application is the engine compartment power supply system for a ship according to claim 1, wherein the I / O unit is replaced with an I / O unit that can be transmitted by a LAN wire, and a PLC that supports AC440V. It is an I / O unit which can be transmitted with the AC440V power cable in a ship.

本考案は、上述のとおり構成されているので、次に記載する効果を奏する。   Since this invention is comprised as mentioned above, there exists an effect described below.

各動力機器の制御器からの信号をアナログからデジタル信号に変換し、コンピュータネットワークを介して伝送ラインの兼用化を図ったことにより、電線長の削減ができるため現場工数の削減の効果がある。また、多芯線の結線作業がなくなることによる結線作業工数の削減及び誤結線がなくなる。更に、集合始動器盤を中止することにより主配電盤のコンパクト化を図ることが可能となる。   By converting the signal from the controller of each power device from analog to digital and using the transmission line via the computer network, the length of the electric wire can be reduced, so that the number of on-site man-hours can be reduced. In addition, the number of connection work man-hours and erroneous connection are eliminated due to the elimination of the multi-core wire connection work. Furthermore, the main switchboard can be made compact by stopping the collective starter panel.

本考案にかかる船舶における機関区画給電システムを実施するための最良の形態を実施例1を図面に基づいて詳細に説明する。   The best mode for carrying out an engine compartment power feeding system in a ship according to the present invention will be described in detail with reference to the drawings.

図1は、本実施例1にかかる船舶における機関区画給電システムの概略を示す図であり、従来の概略図3に対応する図である。図1中、符号1は、デッキ101上の機関室100近傍に配置される前記機関制御盤兼監視盤107に接続される給電盤兼集合始動器盤であり、I/Oユニット2を備えている。また、11は、デッキ102上に配置される前記ポンプおよび電動機108、110に接続され給電・始動の信号等を送る給電盤兼集合始動器盤であり、I/Oユニット12を備えている。同様に、21は、デッキ103上に配置される前記ポンプおよび電動機116、118に接続され給電・始動の信号等を送る給電盤兼集合始動器盤であり、I/Oユニット22を備えている。なお、図1中の符号において、従来の機器は図3において使用した符号と同じ符号で示し、図3において示したと同様に、前記AC440V給電線を濃実線で、前記遠隔発停止電線を波線で前記計装信号線(アナログ信号)を点線で示す。   FIG. 1 is a diagram illustrating an outline of the engine compartment power feeding system in the ship according to the first embodiment, and corresponds to the conventional schematic diagram 3. In FIG. 1, reference numeral 1 denotes a power supply panel / collective starter panel connected to the engine control panel / monitoring panel 107 disposed in the vicinity of the engine room 100 on the deck 101, and includes an I / O unit 2. Yes. Reference numeral 11 denotes a power feeding panel and collective starter panel that is connected to the pump and the motors 108 and 110 disposed on the deck 102 and sends power feeding / starting signals and the like, and includes an I / O unit 12. Similarly, reference numeral 21 denotes a power feeding panel / collective starter panel that is connected to the pump and the motors 116 and 118 disposed on the deck 103 and sends power feeding / starting signals and the like, and includes an I / O unit 22. . In the reference numerals in FIG. 1, the conventional devices are indicated by the same reference numerals as those used in FIG. 3, and the AC440V power supply line is a solid line and the remote stop electric wire is a wavy line, as shown in FIG. The instrumentation signal line (analog signal) is indicated by a dotted line.

従来の船舶における機関区画給電システムにおいて、多芯線化を図ることにより、省配線化は可能となったが、アナログ信号伝送はそのままのため、結線作業及び電線布設占有面積は多芯線化を図る以前と変わっておらず、また、電線長が長いので現場工数が多く掛かってしまうという問題があり、そこで、電線布設占有面積を減少させ結線作業を軽減可能な区画別給電方式として採用したのが、上記実施例1に係る船舶における機関区画給電システムである。   In the conventional engine compartment power supply system for ships, it has become possible to reduce wiring by using multi-core wires, but analog signal transmission remains the same, so the wiring work and the wiring installation occupation area are before the multi-core wires are planned In addition, there is a problem that it takes a lot of man-hours on site because the wire length is long, so that it was adopted as a power supply method by section that can reduce the wiring installation occupation area and reduce the wiring work, 2 is an engine compartment power supply system for a ship according to the first embodiment.

本実施例1に係る船舶における機関区画給電システムにおける前記給電盤兼集合始動器盤11には、各部の監視のためのセンサ113、114、115が接続され、同様に、前記給電盤兼集合始動器盤21には、各部の監視のためのセンサ121、122、123が接続され、これらの給電盤兼集合始動器盤1、給電盤兼集合始動器盤11、給電盤兼集合始動器盤21は、それぞれ内部にI/Oユニット2、12、22を備え、各I/Oユニット2、12、22間がLAN電線で接続される。なお、LAN電線は、図1においては、二点鎖線で示す。   Sensors 113, 114, and 115 for monitoring each part are connected to the power feeding panel and collective starter panel 11 in the engine compartment power feeding system in the ship according to the first embodiment. Sensor 121, 122, 123 for monitoring each part is connected to instrument panel 21, and these feeder panel / collective starter panel 1, feeder panel / collector starter panel 11, feeder panel / collector starter panel 21. Are respectively provided with I / O units 2, 12, and 22, and the I / O units 2, 12, and 22 are connected by LAN wires. In addition, a LAN electric wire is shown with a dashed-two dotted line in FIG.

図1に示すように、本実施例1に係る船舶における機関区画給電システムにおいては、各機器(例えば電動機)の始動器の制御、状態監視回路構成をデジタル対応型に変更し、各機器からデジタル信号が出力出来るようにする。あわせて、伝送ライン(LAN電線)を機関区画内に布設する。そして、推進補機始動の主配電盤組込集合始動器盤を各区画に給電盤を含めた集合始動器盤にし、区画完結型の艤装方法としたものである。本実施例1に係る船舶における機関区画給電システムにおける前記伝送ライン(LAN電線)は、コンピュータネットワークを使用した機関区画内LANシステムであり、機関区画の各デッキ毎に始動器やI/Oユニットなどのセクションボードを構成し、各デッキ上のアナログ信号をセクションボードに集約させ各信号をコンピュータネットワークを使用して機関制御盤兼監視盤へ伝送するものである。   As shown in FIG. 1, in the engine compartment power supply system for a ship according to the first embodiment, the starter control and state monitoring circuit configuration of each device (for example, an electric motor) is changed to a digital compatible type, and the digital Enable signal output. In addition, a transmission line (LAN wire) is laid in the engine compartment. Then, the main switchboard built-in collective starter panel for starting the propulsion auxiliary machine is made into a collective starter panel including a power feeding panel in each section, and a section-completed outfitting method is obtained. The transmission line (LAN wire) in the engine compartment power supply system in the ship according to the first embodiment is a LAN system in the engine compartment using a computer network, and a starter, an I / O unit, etc. for each deck of the engine compartment The section board is configured, the analog signals on each deck are aggregated on the section board, and each signal is transmitted to the engine control panel / monitoring board using a computer network.

これを従来の計装信号線との関係で見れば、本実施例1に係る船舶における機関区画給電システムによれば、アナログ信号を送受する前記計装信号線(点線で示される)は、図1に示されるように、デッキ102では、前記給電盤兼集合始動器盤11と前記ポンプおよび電動機108、110の間および各センサ113、114、115との間だけであり、また、デッキ103では、前記給電盤兼集合始動器盤21と前記ポンプおよび電動機117、119の間および各センサ121、122、123との間だけであり、これまで必要とされていた前記機関制御盤兼監視盤107と前記各ポンプおよび電動機108、110、116、118との間を接続する計装信号線が不要となり、電線長の削減ができることはもとより、それを敷設するための現場工数を削減でき、さらには、多芯線の結線作業がなくなることによる結線作業工数の削減及び誤結線がなくなる。そして、それは、メンテナンス作業の負担を軽減し、さらには、これらの計装信号線の接続やメンテナンスの便宜のために配置が必要とされていた前記多芯線接続箱112、120自体が不要となり、また、発電機盤およびAC440V給電盤からなる前記主配電盤105の近傍に配置されるNo.1集合始動器盤104およびNo.2集合始動器盤106が不要となり、主配電盤のコンパクト化される等配置スペースが簡略化される。   Looking at this in relation to the conventional instrumentation signal line, according to the engine compartment power supply system in the ship according to the first embodiment, the instrumentation signal line (indicated by a dotted line) for transmitting and receiving analog signals is shown in FIG. 1, in the deck 102, only between the power feeding panel and collective starter panel 11 and the pumps and motors 108, 110 and between the sensors 113, 114, 115, The engine control panel / monitoring panel 107, which has been required so far, is only between the power feeding panel / collective starter panel 21 and the pumps and motors 117, 119 and between the sensors 121, 122, 123. And the above-mentioned pumps and motors 108, 110, 116, 118 are not required to be equipped with instrumentation signal wires, and the wire length can be reduced and installed. It can reduce the field number of steps because, furthermore, reduction and improper wiring of wiring man-hours by the connecting operation of the multifilamentary wire is eliminated is eliminated. And, it reduces the burden of maintenance work, and further, the multi-core connection box 112, 120 itself that is required to be arranged for the connection of these instrumentation signal lines and the convenience of maintenance becomes unnecessary. Further, No. 1 arranged in the vicinity of the main switchboard 105 including a generator panel and an AC440V power supply panel. 1 collective starter panel 104 and No. 1 The two collective starter panels 106 are not required, and the arrangement space of the main switchboard is reduced, and the arrangement space is simplified.

次に、本考案にかかる船舶における機関区画給電システムを実施するための最良の形態を実施例2を図面に基づいて詳細に説明する。   Next, the best mode for carrying out the engine compartment power supply system in a ship according to the present invention will be described in detail with reference to the second embodiment.

図2は、本実施例2に係る船舶における機関区画給電システムの概略を示す図であり、図2において、符号51は、前記デッキ101上の機関室100近傍に配置される前記機関制御盤兼監視盤107に接続される給電盤兼集合始動器盤であり、52は、その内部に配置されるI/Oユニット、61は、前記デッキ102上に配置される前記ポンプおよび電動機108、110に接続され給電・始動の信号等を送る給電盤兼集合始動器盤であり、62は、その内部に配置されるI/Oユニット、71は、前記デッキ103上に配置される前記ポンプおよび電動機116、118に接続され給電・始動の信号等を送る給電盤兼集合始動器盤であり、72は、その内部に配置されるI/Oユニットである。各I/Oユニット52、62、72から図2において薄実線で示される船舶動力ケーブルを介して通信が維持される。   FIG. 2 is a diagram showing an outline of an engine compartment power feeding system in a ship according to the second embodiment. In FIG. 2, reference numeral 51 denotes the engine control panel that is disposed in the vicinity of the engine room 100 on the deck 101. A power supply panel / collective starter panel connected to the monitoring panel 107, 52 is an I / O unit disposed therein, and 61 is a pump and motors 108 and 110 disposed on the deck 102. A power feeding board and collective starter board connected to send power feeding / starting signals and the like, 62 is an I / O unit disposed therein, 71 is the pump and motor 116 disposed on the deck 103 , 118 is a power feeding panel / collective starter panel that sends power feeding / starting signals and the like, and 72 is an I / O unit disposed therein. Communication is maintained from each I / O unit 52, 62, 72 via a ship power cable indicated by a thin solid line in FIG.

なお、本実施例2に係る船舶における機関区画給電システムも、基本的には上記実施例1に係る船舶における機関区画給電システムと同様にコンピュータネットワークを使用した機関区画内LANシステムであり、機関区画の各デッキ毎に始動器やI/Oユニットなどのセクションボードを構成し、各デッキ上のアナログ信号をセクションボードに集約させ各信号をコンピュータネットワークを使用して機関制御盤兼監視盤へ伝送するものであるが、船舶内で使用されるネットワークは、鋼鉄製で各部署が区画されているので、無線LANを使用することはできない。そこで、本実施例2に係る船舶における機関区画給電システムは、図2に示されるように、上記実施例1に係る船舶における機関区画給電システムとは異なり、上記実施例1で使用する前記給電盤兼集合始動器盤1、I/Oユニット2、前記給電盤兼集合始動器盤11、I/Oユニット12、前記給電盤兼集合始動器盤21、I/Oユニット22に替え、給電盤兼集合始動器盤51、I/Oユニット52、前記給電盤兼集合始動器盤61、I/Oユニット62、前記給電盤兼集合始動器盤71、I/Oユニット72で構成したものである。すなわち、本実施例2に係る船舶における機関区画給電システムは、上記実施例1のLAN電線で伝送するデジタル信号を動カケーブル(図2において、薄実線で示す)に重畳させて信号ラインの削減を図ったものである。   The engine compartment power supply system in the ship according to the second embodiment is also an engine compartment LAN system that uses a computer network in the same manner as the engine compartment power supply system in the ship according to the first embodiment. Section boards such as starters and I / O units are configured for each deck, and the analog signals on each deck are aggregated into the section board and each signal is transmitted to the engine control panel and monitoring panel using a computer network. However, since the network used in the ship is made of steel and each section is partitioned, the wireless LAN cannot be used. Therefore, the engine compartment power supply system in the ship according to the second embodiment is different from the engine compartment power supply system in the ship according to the first embodiment, as shown in FIG. In addition to the power collection panel 1, the I / O unit 2, the power supply panel / collective starter panel 11, the I / O unit 12, the power supply panel / collective starter panel 21, and the I / O unit 22, A collective starter panel 51, an I / O unit 52, the power supply panel / collective starter panel 61, an I / O unit 62, the power supply panel / collective starter panel 71, and an I / O unit 72 are included. That is, the engine compartment power supply system in the ship according to the second embodiment reduces the signal line by superimposing the digital signal transmitted by the LAN wire of the first embodiment on the moving cable (shown by a thin solid line in FIG. 2). Is intended.

ここに使用するI/Oユニット52、62、72は、いずれもPLC(パワーラインコミュニケーション)対応のI/Oユニットであり、従来、家庭等で使用されるAC100V対応のものをそのまま使用するわけには行かない。そこで、船舶で使用されるAC440V動力ケーブルに重畳できるものを新たに開発して構成したものである。   The I / O units 52, 62, and 72 used here are all I / O units compatible with PLC (power line communication), and the conventional ones that are compatible with 100V AC used at home are used as they are. Will not go. Therefore, a device that can be superposed on an AC440V power cable used in a ship is newly developed and configured.
