Description

本発明は、制御盤に関する。   The present invention relates to a control panel.

図６を参照して、既設の制御盤の構成について説明する。既設制御盤の筐体１１の前面開口部には、前面メンテナンス用の扉１３が取付けられている。筐体１１の内部には、中柱１２および中柱１２に実装された各機器が収められている。中柱１２には、既設ＩＯユニット１４、既設電源取付パネル１６、既設電気用品取付パネル１７が実装されている。既設ＩＯユニット１４には、さらに既設ＩＯユニット用外線コネクタ１９が実装されている。既設ＩＯユニット用外線コネクタ１９には、外部に接続する既設外線ケーブル１８が配線されている。既設外線ケーブル１８は、制御盤外部との信号送受信や電力供給のために用いられる。また、既設ＩＯユニット１４には既設ＩＯ１５が収納されている。既設ＩＯ１５は、既設ＩＯユニット１４を介して既設外線ケーブル１８に電気的に接続している。   The configuration of the existing control panel will be described with reference to FIG. A front maintenance door 13 is attached to a front opening of the housing 11 of the existing control panel. Inside the housing 11, a center pillar 12 and devices mounted on the center pillar 12 are stored. On the middle pillar 12, an existing IO unit 14, an existing power supply mounting panel 16, and an existing electric appliance mounting panel 17 are mounted. An existing IO unit external line connector 19 is further mounted on the existing IO unit 14. The existing external cable 18 for external connection is wired to the external line connector 19 for the existing IO unit. The existing external cable 18 is used for signal transmission / reception with the outside of the control panel and power supply. The existing IO unit 14 houses the existing IO 15. The existing IO 15 is electrically connected to the existing external cable 18 via the existing IO unit 14.

図７を参照して、従来の制御盤更新手法にて既設ＩＯを新設ＩＯに更新する場合の更新後の構成について説明する。従来の制御盤更新手法では、新設制御盤を既設制御盤と同一の電気室のスペースに設置する（特許文献１等）。新設制御盤の筐体２１の中柱２２には、新設ＩＯユニット３４が実装される。既設制御盤の筐体１１内の既設ＩＯユニット１４（図６）は撤去され、中柱１２には、更新用中継端子台２５が実装される。既設ＩＯユニット１４に配線されていた既設外線ケーブル１８は、更新用中継端子台２５に配線し直される。更新用中継端子台２５と新設ＩＯユニット３４の間は、追加外線ケーブル２８で結線される。   With reference to FIG. 7, a description will be given of a configuration after updating when an existing IO is updated to a new IO by a conventional control panel updating method. In the conventional control panel updating method, a new control panel is installed in the same electric room space as an existing control panel (Patent Document 1 and the like). A new IO unit 34 is mounted on the middle pillar 22 of the housing 21 of the new control panel. The existing IO unit 14 (FIG. 6) in the housing 11 of the existing control panel is removed, and the intermediate pillar 12 is mounted with the relay terminal block 25 for updating. The existing external cable 18 wired to the existing IO unit 14 is rewired to the update relay terminal block 25. The update relay terminal block 25 and the new IO unit 34 are connected by an additional external cable 28.

特開２００６−３１１６３１号公報JP 2006-316331 A

従来の制御盤更新手法では、既設外線ケーブルを流用するために、既設制御盤内の既設ＩＯユニットを撤去し、そのあと既設制御盤を中継端子台化している。中継端子台化するためには、現地での改造期間を十分に確保する必要がある。また、既設ＩＯユニットが撤去されて既設制御盤に戻すことができないこと、および、既設ＩＯユニットを撤去した後にしか新設ＩＯの動作確認を行うことができないことから、現地での更新に際して十分なシステム試験期間を確保する必要がある。そのため、設備停止期間が長期化する問題があった。   In the conventional control panel updating method, in order to divert an existing external cable, an existing IO unit in the existing control panel is removed, and then the existing control panel is used as a relay terminal block. In order to make it a relay terminal block, it is necessary to secure a sufficient period of remodeling on site. In addition, since the existing IO unit is removed and cannot be returned to the existing control panel, and the operation of the new IO can be checked only after removing the existing IO unit, a sufficient system for updating on site is needed. It is necessary to secure a test period. For this reason, there has been a problem that the equipment suspension period is prolonged.

本発明は、上述のような課題を解決するためになされたもので、既設ＩＯの撤去前に新設ＩＯを用いたシステム試験を行うことができ、既設設備を短期間で更新できる制御盤を提供することを目的とする。   The present invention has been made to solve the above-described problems, and provides a control panel that can perform a system test using a new IO before removing the existing IO and can update the existing equipment in a short period of time. The purpose is to do.

上記目的の達成のため、本発明に係る制御盤は、既設ＩＯ、新設ＩＯ、新設ＩＯ用盤内線ケーブル、既設ＩＯユニット、中継アダプタを備える。   To achieve the above object, a control panel according to the present invention includes an existing IO, a new IO, a board extension cable for a new IO, an existing IO unit, and a relay adapter.

新設ＩＯ用盤内線ケーブルは、一端が新設ＩＯに取り付けられ、他端が中継アダプタに取り付けられる。既設ＩＯユニットは、既設ＩＯユニット用外線コネクタを有し、該コネクタを介して既設外線ケーブルに接続する。   One end of the new IO extension cable is attached to the new IO, and the other end is attached to the relay adapter. The existing IO unit has an external line connector for the existing IO unit, and is connected to the existing external line cable via the connector.

中継アダプタは、既設ＩＯと既設ＩＯユニットとの間に装着されて既設ＩＯと既設外線ケーブルとを電気的に接続する。さらに、中継アダプタは、新設ＩＯ用盤内線ケーブルの他端が取り付けられて新設ＩＯと既設外線ケーブルとを電気的に接続する。なお、中継アダプタは他の機器（既設ＩＯ、既設ＩＯユニット、新設ＩＯ用盤内線ケーブル）とワンタッチで接続できることが好ましい。   The relay adapter is mounted between the existing IO and the existing IO unit, and electrically connects the existing IO to the existing external cable. Furthermore, the other end of the new IO internal cable is attached to the relay adapter to electrically connect the new IO to the existing external cable. It is preferable that the relay adapter can be connected to other devices (existing IOs, existing IO units, and new IO internal extension cables) with one touch.

このような中継アダプタを用いることで、従来の制御盤更新手法のように、既設制御盤を中継端子台化して既設外線ケーブルを接続し直す作業が不要になる。また、中継アダプタを用いることで、既設ＩＯユニットを撤去することなく、既設ＩＯと新設ＩＯの両方を既設外線ケーブルに接続することができる。そのため、既設ＩＯで設備を運転している期間に新設ＩＯの動作確認を行うことができ、システム試験における設備停止期間を短縮することができる。また、新旧システムの切換によるシステム試験を行うことにより、設計品質を向上させることができる。   By using such a relay adapter, it is not necessary to convert the existing control panel into a relay terminal block and reconnect the existing external cable as in the conventional control panel updating method. Also, by using the relay adapter, both the existing IO and the new IO can be connected to the existing external cable without removing the existing IO unit. Therefore, it is possible to confirm the operation of the new IO while the equipment is operating on the existing IO, and it is possible to shorten the equipment stoppage period in the system test. Further, by performing a system test by switching between a new system and an old system, design quality can be improved.

１つの態様では、制御盤は、筐体前方増設枠と新設ＩＯユニットとをさらに備える。筐体前方増設枠は、制御盤の筐体の前面開口部に装着される。新設ＩＯユニットは、筐体前方増設枠に取り付けられる。新設ＩＯは、新設ＩＯユニットに収納される。   In one aspect, the control panel further includes an additional frame at the front of the housing and a new IO unit. The enclosure front extension frame is attached to the front opening of the enclosure of the control panel. The new IO unit is attached to the front extension frame of the housing. The new IO is stored in the new IO unit.

このような筐体前方増設枠を用いることで、既設制御盤に新設ＩＯを増設できるため、従来の制御盤更新手法における新設制御盤を設ける必要がない。そのため、既設制御盤と外部の新設制御盤との間を結線する追加外線ケーブル２８（図７）は不要である。追加外線ケーブル２８よりも長さの短い新設ＩＯ用盤内線ケーブル（例えば、数ｍ）で新設ＩＯと中継アダプタとを結線すれば足りる。このため、更新コスト、設置スペースともに改善が図られる。   By using such an extension frame at the front of the housing, a new IO can be added to the existing control panel, and thus it is not necessary to provide a new control panel in the conventional control panel update method. Therefore, the additional external cable 28 (FIG. 7) for connecting between the existing control panel and the external new control panel is unnecessary. It is sufficient to connect the newly-installed IO and the relay adapter with a newly-installed IO board extension cable (for example, several meters) shorter in length than the additional external cable 28. Therefore, both the renewal cost and the installation space are improved.

本発明に係る制御盤によれば、既設ＩＯの撤去前に新設ＩＯを用いたシステム試験を行うことができ、容易かつ短期間に既設設備を更新できる。   ADVANTAGE OF THE INVENTION According to the control panel which concerns on this invention, a system test using a new IO can be performed before removal of the existing IO, and existing equipment can be updated easily and in a short time.

However, in the embodiments described below, when referring to the number of each element, such as the number, quantity, amount, range, etc. The present invention is not limited to such a number. The structures and the like described in the embodiments described below are not necessarily essential to the present invention, unless otherwise specified or clearly specified in principle. In the drawings, common elements are denoted by the same reference numerals, and redundant description is omitted.

実施の形態１．
本実施形態に係る既設制御盤のＩＯの更新について説明する。 Embodiment 1 FIG.
Update of the IO of the existing control panel according to the present embodiment will be described.

図１は、筐体前方増設枠を筐体に装着する前の制御盤の構成図である。制御盤の筐体１１の内部構成は、次の点を除き上述した図６と同じである。図１では、筐体１１の前面の扉１３（図６）が取り外されている。また、既設ＩＯ１５と既設ＩＯユニット１４との間には、中継アダプタ３６が装着されている。また、上述した図７と比較すると、本実施形態ではＩＯ更新後においても、既設ＩＯユニット１４は中柱１２に実装されている。そして既設ＩＯユニット１４の既設ＩＯユニット用外線コネクタ１９には、既設外線ケーブル１８が結線されたままである。   FIG. 1 is a configuration diagram of a control panel before the front frame of the housing is mounted on the housing. The internal configuration of the casing 11 of the control panel is the same as that of FIG. 6 except for the following points. In FIG. 1, the door 13 (FIG. 6) on the front surface of the housing 11 is removed. In addition, a relay adapter 36 is mounted between the existing IO 15 and the existing IO unit 14. Further, in comparison with FIG. 7 described above, in the present embodiment, the existing IO unit 14 is mounted on the center pillar 12 even after the IO update. The existing external cable 18 is still connected to the existing IO unit external line connector 19 of the existing IO unit 14.

次に、前面メンテナンス用の筐体前方増設枠３１について説明する。筐体前方増設枠３１の背面側は開口しており、扉１３が取り外された筐体１１の前面開口部に取り付け可能である。筐体前方増設枠３１の前面側は開口しており、外扉３３が取り付けられている。筐体前方増設枠３１には、新設ＩＯユニット３４が取り付けられている。新設ＩＯユニット３４は、既設ＩＯユニット１４の正面に取付けることが望ましい。新設ＩＯユニット３４には、新設ＩＯ３５が収納されている。   Next, the front frame 31 for front maintenance will be described. The back side of the front frame 31 is open and can be attached to the front opening of the housing 11 from which the door 13 has been removed. The front side of the front frame 31 is open, and an outer door 33 is attached. A new IO unit 34 is attached to the front extension frame 31 of the housing. The new IO unit 34 is desirably attached to the front of the existing IO unit 14. The new IO unit 34 stores a new IO 35.

図２は、筐体前方増設枠３１を筐体に装着した後の制御盤の構成図である。筐体１１の前面開口部に筐体前方増設枠３１の背面開口部が装着される。新設ＩＯ用盤内線ケーブル３８は、一端が新設ＩＯ３５に取り付けられ、他端が中継アダプタ３６に取り付けられる。新設ＩＯユニット３４を既設ＩＯユニット１４の正面に取付けることで、新設ＩＯ用盤内線ケーブル３８の長さは最も短くて済む。   FIG. 2 is a configuration diagram of the control panel after the housing front extension frame 31 is mounted on the housing. The rear opening of the front frame 31 is attached to the front opening of the housing 11. One end of the new IO board extension cable 38 is attached to the new IO 35, and the other end is attached to the relay adapter 36. By attaching the new IO unit 34 to the front of the existing IO unit 14, the length of the new IO panel extension cable 38 can be minimized.

このような筐体前方増設枠３１を用いることで、既設制御盤に新設ＩＯ３５を増設でき、また、長さの短い新設ＩＯ用盤内線ケーブル３８（例えば、数ｍ）で新設ＩＯ３５と中継アダプタ３６とを結線できる。このため、更新コスト、設置スペースともに改善が図られる。   By using such a front extension frame 31, a new IO 35 can be added to the existing control panel, and the new IO 35 and the relay adapter 36 are connected to the new IO panel extension cable 38 (for example, several meters) having a short length. And can be connected. Therefore, both the renewal cost and the installation space are improved.

図３〜図５を参照して、中継アダプタ３６の接続状態について説明する。図３に示すように、中継アダプタ３６は、既設ＩＯ用コネクタ５１、既設ＩＯユニット用コネクタ５２、新設ＩＯ用コネクタ５３を備える。   The connection state of the relay adapter 36 will be described with reference to FIGS. As shown in FIG. 3, the relay adapter 36 includes an existing IO connector 51, an existing IO unit connector 52, and a new IO connector 53.

図４は、中継アダプタ３６の配線図である。中継アダプタ３６を既設ＩＯユニット１４に収納することにより、既設ＩＯユニット用外線コネクタ１９と既設ＩＯユニット用コネクタ５２とが結線される。既設ＩＯユニット用コネクタ５２と既設ＩＯ用コネクタ５１は、中継アダプタ３６の内部で結線されている。また、既設ＩＯユニット用コネクタ５２と新設ＩＯ用コネクタ５３も、中継アダプタ３６の内部で結線されている。これにより、既設ＩＯユニット用外線コネクタ１９は、既設ＩＯ用コネクタ５１および新設ＩＯ用コネクタ５３にそれぞれ電気的に接続される。   FIG. 4 is a wiring diagram of the relay adapter 36. By storing the relay adapter 36 in the existing IO unit 14, the existing IO unit external line connector 19 and the existing IO unit connector 52 are connected. The existing IO unit connector 52 and the existing IO connector 51 are connected inside the relay adapter 36. The existing IO unit connector 52 and the new IO connector 53 are also connected inside the relay adapter 36. As a result, the existing IO unit external line connector 19 is electrically connected to the existing IO connector 51 and the new IO connector 53, respectively.

図５は、中継アダプタ３６周辺の接続状態を説明するための図である。中継アダプタ３６は、既設ＩＯ用コネクタ５１（図４）により既設ＩＯ１５に直接接続している。中継アダプタ３６は、既設ＩＯユニット用コネクタ５２（図４）により既設ＩＯユニット１４に直接接続している。既設ＩＯユニット１４の既設ＩＯユニット用外線コネクタ１９は既設外線ケーブル１８に接続している。中継アダプタ３６は、新設ＩＯ用コネクタ５３（図４）により新設ＩＯ用盤内線ケーブル３８に接続し、新設ＩＯ用盤内線ケーブル３８を介して新設ＩＯ３５に接続している。   FIG. 5 is a diagram for explaining a connection state around the relay adapter 36. The relay adapter 36 is directly connected to the existing IO 15 via the existing IO connector 51 (FIG. 4). The relay adapter 36 is directly connected to the existing IO unit 14 by the existing IO unit connector 52 (FIG. 4). The existing IO unit external line connector 19 of the existing IO unit 14 is connected to the existing external line cable 18. The relay adapter 36 is connected to a new IO board extension cable 38 by a new IO connector 53 (FIG. 4), and is connected to the new IO 35 via the new IO board extension cable 38.

そのため、既設ＩＯ１５と新設ＩＯ３５の両方が、中継アダプタ３６と既設ＩＯユニット１４とを介して、既設外線ケーブル１８と電気的に接続している。したがって、既設外線ケーブル１８から既設ＩＯユニット１４へ入力される信号は、既設ＩＯ１５と新設ＩＯ３５とに入力される。そのため、既設ＩＯ１５で設備を運転している期間に新設ＩＯ３５の動作確認を行うことができ、システム試験における設備停止期間を短縮することができる。また、新旧システムの切換によるシステム試験を行うことにより、設計品質を向上させることができる。   Therefore, both the existing IO 15 and the new IO 35 are electrically connected to the existing external cable 18 via the relay adapter 36 and the existing IO unit 14. Therefore, a signal input from the existing external cable 18 to the existing IO unit 14 is input to the existing IO 15 and the new IO 35. Therefore, the operation of the new IO 35 can be checked while the existing IO 15 is operating the equipment, and the equipment stop period in the system test can be shortened. Further, by performing a system test by switching between a new system and an old system, design quality can be improved.

以上、本発明の実施の形態について説明したが、本発明は、上記の実施の形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲で種々変形して実施することができる。   Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and can be variously modified and implemented without departing from the spirit of the present invention.
