Abstract

PROBLEM TO BE SOLVED: To facilitate the identification of power cable connection with a highly versatile system.SOLUTION: A power connection device includes: a first and a second power connection unit forming a power supply path therebetween; a control unit having a function to detect a predetermined signal arriving at the first power connection unit from the outside and a function to enable the transmission of a signal having the same format as the predetermined signal to the second power connection unit; a notification unit for issuing a predetermined notification when the control unit detects the predetermined signal; and a switch unit for supplying the control unit with an instruction to transmit the signal having the same format as the predetermined signal.

Description

本発明は、電源接続装置および接続確認方法に係り、特に、電源ケーブルの接続技術に係る。   The present invention relates to a power connection device and a connection confirmation method, and more particularly to a power cable connection technique.

近年、システムセンター、サーバルームなどでは、一つの架（筐体）に複数のサーバ、端末などの機器（情報処理装置など）が設置されており、テーブルタップに複数台の機器の電源プラグが接続されていることが多い。このようなシステムでは、点検や工事を行うとき、抜いてはいけない機器の電源プラグを、誤ってテーブルタップなどの電力分配器から抜いてしまう可能性がある。その場合、機器の利用者の通信が切断されるなどの障害が発生する。   In recent years, in system centers, server rooms, etc., multiple devices such as servers and terminals (information processing devices, etc.) are installed on a single rack (casing), and the power plugs of multiple devices are connected to the table tap. It is often done. In such a system, when performing inspection or construction, there is a possibility that a power plug of a device that should not be removed is mistakenly removed from a power distributor such as a table tap. In that case, a failure such as disconnection of communication of the user of the device occurs.

そこで、特許文献１において、機器の電源プラグを電力分配器から誤って抜き取ることを防止する誤抜防止装置が開示されている。電源遮断制御部は、機器の電源プラグを電力分配器のコンセントから抜き取り可能であるか否かが設定された電源遮断判定情報を受信し、受信した電源遮断判定情報の設定に基づいて高周波に変換した電源遮断判定信号を生成し、供給元電源から機器が有する電源部へ電力を供給する電力線の電力信号と、電源遮断判定信号とを合成する。電力分配器は、電源遮断制御部から送信された電力信号から電源遮断判定信号を抽出して、電源遮断判定情報を復調し、高周波信号受信部において復調された電源遮断判定情報が、機器の電源プラグを電力分配器のコンセントから抜き取り可能であることを示すとき、抜き取り可能であることを表示する指示を状態表示器にする。   Therefore, Patent Document 1 discloses an erroneous disconnection prevention device that prevents a power supply plug of a device from being accidentally extracted from a power distributor. The power shutoff control unit receives the power shutoff determination information in which it is set whether or not the power plug of the device can be removed from the outlet of the power distributor, and converts it to a high frequency based on the setting of the received power shutoff determination information The power-off determination signal is generated, and the power signal of the power line that supplies power from the supply source to the power supply unit of the device and the power-off determination signal are combined. The power distributor extracts a power cutoff judgment signal from the power signal transmitted from the power cutoff controller, demodulates the power cutoff judgment information, and the power cutoff judgment information demodulated by the high frequency signal receiver is When indicating that the plug can be removed from the outlet of the power distributor, an indication indicating that the plug can be removed is displayed on the status indicator.

また、ケーブルの一端にあるコネクタにＬＥＤ（Light Emitting Diode）を設け、ケーブルの反対側にあるコネクタにスイッチを設けることにより、スイッチのＯＮあるいはＯＦＦによりＬＥＤの点灯あるいは消灯を確認し、ケーブルの両端が明確になることにより、ケーブルの保守性を改善するＬＥＤ確認コネクタが特許文献２において開示されている。   Also, an LED (Light Emitting Diode) is provided on the connector at one end of the cable, and a switch is provided on the connector on the opposite side of the cable, so that the LED is turned on or off by turning the switch on or off. As a result, the LED check connector that improves the maintainability of the cable is disclosed in Patent Document 2.

特開２０１０−２８７０１４号公報JP 2010-287014 A 特開２００８−１９２５８３号公報JP 2008-192583 A

以下の分析は本発明において与えられる。   The following analysis is given in the present invention.

ところで、特許文献１に開示される誤抜防止装置では、テーブルタップ、電源タップあるいは電源盤に相当する電力分配器にＬＥＤなどの状態表示器を備えている。また、電源遮断判定信号を生成する電源遮断制御部は、情報処理装置からの指示によって動作する。したがって、既存の情報処理装置と既存の電源タップを有するシステムに適用しようとする場合、新たに電源遮断制御部を設けて、情報処理装置に新たな処理機能を付加すると共に、専用の電力分配器を設置しなければならない。すなわち、既存の装置の置き換えが必要であり、汎用性に欠けるシステムであると言える。   By the way, in the error prevention device disclosed in Patent Document 1, a power indicator corresponding to a table tap, a power tap, or a power panel is provided with a status indicator such as an LED. Further, the power cutoff control unit that generates the power cutoff judgment signal operates according to an instruction from the information processing apparatus. Therefore, when applying to a system having an existing information processing apparatus and an existing power strip, a new power-off control unit is newly provided to add a new processing function to the information processing apparatus, and a dedicated power distributor Must be installed. In other words, it can be said that the system needs to be replaced with an existing device and lacks versatility.

また、特許文献２に開示されるＬＥＤ確認コネクタは、コネクタ間の配線の３本を利用してＬＥＤの表示の確認を行うものであって、配線が異なるコネクタ毎に新規に製作されるべきものである。したがって、汎用性に欠けると共に電源ケーブルに適用することは不可能である。   Moreover, the LED confirmation connector disclosed in Patent Document 2 is for confirming the LED display using three wirings between the connectors, and should be newly manufactured for each connector having a different wiring. It is. Therefore, it is not versatile and cannot be applied to a power cable.

したがって、本発明の目的は、汎用性の高いシステムによって電源ケーブルの接続の特定を容易に行う電源接続装置および接続確認方法を提供することにある。   Accordingly, an object of the present invention is to provide a power connection device and a connection confirmation method for easily specifying the connection of a power cable by a highly versatile system.

本発明の１つのアスペクト（側面）に係る電源接続装置は、２つの間に電源供給経路が形成される第１および第２の電源接続部と、外部より第１の電源接続部に到来する所定の信号を検知する機能と、所定の信号と同一の形式の信号を第２の電源接続部に送出可能とする機能とを有する制御部と、制御部が所定の信号を検知した場合に所定の通知を行う通知部と、所定の信号と同一の形式の信号を送出する指示を制御部に対して与えるスイッチ部と、を備える。   The power connection device according to one aspect (side surface) of the present invention includes first and second power connection portions in which a power supply path is formed between the two, and a predetermined arrival at the first power connection portion from the outside. A control unit having a function of detecting a signal of the above and a function of enabling a signal having the same format as the predetermined signal to be sent to the second power supply connecting unit, and a predetermined unit when the control unit detects the predetermined signal. A notification unit that performs notification, and a switch unit that instructs the control unit to transmit a signal having the same format as the predetermined signal.

本発明の他のアスペクト（側面）に係る接続確認方法は、第１および第２の電源接続装置を電源ケーブルを介して接続するシステムにおける接続確認方法であって、第１の電源接続装置におけるスイッチ部を活性化するステップと、所定の信号を第１の電源接続装置から電源ケーブルを介して送出するステップと、電源ケーブルを介して到来する所定の信号を第２の電源接続装置が検知するステップと、第２の電源接続装置において所定の通知を行うステップと、を含む。   A connection confirmation method according to another aspect of the present invention is a connection confirmation method in a system in which first and second power connection devices are connected via a power cable, and the switch in the first power connection device A step of activating the unit, a step of sending a predetermined signal from the first power connection device via the power cable, and a step of the second power connection device detecting a predetermined signal coming through the power cable And a step of performing a predetermined notification in the second power connection device.

本発明によれば、汎用性の高いシステムによって電源ケーブルの接続を容易に特定することができる。   According to the present invention, the connection of the power cable can be easily specified by a highly versatile system.

以下、実施形態に即し、図面を参照して詳しく説明する。   Hereinafter, it will be described in detail with reference to the drawings according to the embodiment.

［実施形態］
図１は、本発明の一実施形態に係る電源接続部が用いられる電源供給システムの構成を示す図である。図１において、電源供給システムは、電源ユニット１０、ＰＬＣ機器２０ａ、２０ｂ、電源ケーブル３０、ＯＡタップ４０、基幹電源ケーブル５０を備える。 [Embodiment]
FIG. 1 is a diagram showing a configuration of a power supply system in which a power connection unit according to an embodiment of the present invention is used. In FIG. 1, the power supply system includes a power supply unit 10, PLC devices 20 a and 20 b, a power cable 30, an OA tap 40, and a main power cable 50.

電源ユニット１０は、不図示のサーバなどの電子機器の電源ユニットであり、電源ケーブル３０との間にＰＬＣ機器２０ａを接続する。   The power supply unit 10 is a power supply unit of an electronic device such as a server (not shown), and connects the PLC device 20 a to the power cable 30.

ＰＬＣ機器２０ａは、電源ケーブル３０を介してＰＬＣ機器２０ａの一端に接続する。   The PLC device 20 a is connected to one end of the PLC device 20 a via the power cable 30.

ＰＬＣ機器２０ｂは、他端をＯＡタップ（電源タップ）４０に接続する。ＰＬＣ機器２０ａ、２０ｂは、電源ケーブルを通信回線としても利用する電力線搬送通信（ＰＬＣ：Power Line Communication）用の機器であり、電源接続装置として機能する。   The PLC device 20 b connects the other end to an OA tap (power tap) 40. The PLC devices 20a and 20b are devices for power line communication (PLC) using a power cable as a communication line, and function as a power connection device.

ＯＡタップ４０は、商用電源あるいは無停電電源装置（ＵＰＳ：Uninterruptible Power Supply）などに基幹電源ケーブル５０によって接続される電源盤として機能する。基幹電源ケーブル５０から供給される電源は、ＯＡタップ４０に接続される多数の電子機器に対して分配される。   The OA tap 40 functions as a power panel connected by a main power cable 50 to a commercial power source or an uninterruptible power supply (UPS). The power supplied from the main power cable 50 is distributed to many electronic devices connected to the OA tap 40.

次に、ＰＬＣ機器の詳細について説明する。図２は、ＰＬＣ機器２０ａの構成を示すブロック図である。図２において、ＰＬＣ機器２０ａは、電源接続部２１ａ、２１ｂ、ＰＬＣ制御部２２、操作スイッチ２３、ＬＥＤ表示部２４、ＡＣ／ＤＣ変換部２５、データ通信部２６、外部接続端子２７を備える。   Next, details of the PLC device will be described. FIG. 2 is a block diagram showing a configuration of the PLC device 20a. In FIG. 2, the PLC device 20 a includes power connection units 21 a and 21 b, a PLC control unit 22, an operation switch 23, an LED display unit 24, an AC / DC conversion unit 25, a data communication unit 26, and an external connection terminal 27.

電源接続部２１ａは、図１の電源ユニット１０に接続され、電源ユニット１０に電源供給を行う、例えばメス型の形状の接続コネクタを有する。   The power supply connection portion 21a is connected to the power supply unit 10 in FIG. 1 and has a connection connector having a female shape, for example, for supplying power to the power supply unit 10.

電源接続部２１ｂは、電源ケーブル３０の一端に接続され、例えばオス型の形状の接続コネクタを有し、電源ケーブル３０から供給される電源を電源接続部２１ａに供給する。ここで、電源ケーブル３０の一端のコネクタの形状は、電源接続部２１ａの接続コネクタの形状と同一であることが好ましい。   The power connection part 21b is connected to one end of the power cable 30 and has, for example, a male connector, and supplies power supplied from the power cable 30 to the power connection part 21a. Here, the shape of the connector at one end of the power cable 30 is preferably the same as the shape of the connection connector of the power connection portion 21a.

ＰＬＣ制御部２２は、ＡＣ／ＤＣ変換部２５、データ通信部２６を含む。   The PLC control unit 22 includes an AC / DC conversion unit 25 and a data communication unit 26.

ＡＣ／ＤＣ変換部２５は、電源接続部２１ａ、２１ｂ間の配線のＡＣ電圧をＤＣ電圧に変換し、変換されたＤＣ電圧を電源としてデータ通信部２６に供給する。   The AC / DC conversion unit 25 converts the AC voltage of the wiring between the power supply connection units 21a and 21b into a DC voltage, and supplies the converted DC voltage to the data communication unit 26 as a power source.

データ通信部２６は、操作スイッチ２３が操作された（例えば押下された）場合、所定の信号を電源接続部２１ａ、２１ｂ間の配線に対して出力する。所定の信号は、電源接続部２１ｂから電源ケーブル３０に向けて送出される。また、電源接続部２１ｂに到来した所定の信号を受信した場合、データ通信部２６は、ＬＥＤ表示部２４を点灯あるいは点滅させる。ここで、所定の信号とは、ＰＬＣの規格に則った信号であってもよい。また、ＬＥＤ表示部２４は、所定の期間、例えば１０秒間、点灯あるいは点滅させるようにしてもよい。あるいは、所定の信号が到来している間中、点灯あるいは点滅を続けるようにしてもよい。なお、ＬＥＤ表示部２４は、ここではＬＥＤ（Light Emitting Diode）による表示としているが、これに限定されず、他の可視表示や、音による通知、を含む、保守者にとって識別可能な一般的な通知等であればよい。   When the operation switch 23 is operated (for example, pressed), the data communication unit 26 outputs a predetermined signal to the wiring between the power supply connection units 21a and 21b. The predetermined signal is transmitted from the power supply connection portion 21b toward the power cable 30. In addition, when receiving a predetermined signal arriving at the power supply connection unit 21b, the data communication unit 26 lights or blinks the LED display unit 24. Here, the predetermined signal may be a signal conforming to a PLC standard. Moreover, you may make it the LED display part 24 light or blink for a predetermined period, for example, 10 seconds. Alternatively, the lighting or blinking may be continued while a predetermined signal arrives. Here, the LED display unit 24 is a display using an LED (Light Emitting Diode), but is not limited to this, and is a general identifiable for the maintenance person including other visual display and sound notification. Any notification or the like may be used.

なお、操作スイッチ２３が操作された場合に送出される所定の信号は、必ずしもＰＬＣの規格に則った信号である必要は無い。すなわち、電源ユニット１０に接続された電子機器の動作に影響を及ぼさないような周波数帯と信号レベルを有する信号であればよい。例えば、所定の信号は、電源ユニット１０に存在するノイズフィルタで充分にカットされるような信号であればよい。   Note that the predetermined signal sent when the operation switch 23 is operated does not necessarily need to be a signal in accordance with the PLC standard. That is, any signal having a frequency band and a signal level that does not affect the operation of the electronic device connected to the power supply unit 10 may be used. For example, the predetermined signal may be a signal that is sufficiently cut by a noise filter present in the power supply unit 10.

また、データ通信部２６は、外部接続端子２７から入力されるデータ信号をＰＬＣの規格に則った信号に変換して電源接続部２１ｂから電源ケーブル３０に向け送出する。さらに、電源接続部２１ｂに到来したＰＬＣの規格に則った信号を変換して得たデータ信号を外部接続端子２７に出力する。すなわち、データ通信部２６は、通常知られたＰＬＣ用の通信機能をも有する。   In addition, the data communication unit 26 converts the data signal input from the external connection terminal 27 into a signal conforming to the PLC standard, and transmits the signal to the power cable 30 from the power connection unit 21b. Further, a data signal obtained by converting a signal conforming to the PLC standard arriving at the power supply connection unit 21 b is output to the external connection terminal 27. That is, the data communication unit 26 also has a generally known PLC communication function.

図３は、ＰＬＣ機器２０ｂの構成を示すブロック図である。図３において、図２と同一の符号は、同一物を表し、その説明を省略する。   FIG. 3 is a block diagram showing a configuration of the PLC device 20b. 3, the same reference numerals as those in FIG. 2 represent the same items, and the description thereof is omitted.

電源接続部２１ｃは、電源ケーブル３０の他端に接続され、電源ケーブル３０に電源供給を行う、例えばメス型の形状の接続コネクタを有する。   The power connection part 21c is connected to the other end of the power cable 30 and has, for example, a female connector for supplying power to the power cable 30.

電源接続部２１ｄは、ＯＡタップ４０に接続され、例えばオス型の形状の接続コネクタを有し、ＯＡタップ４０から供給される電源を電源ケーブル３０に供給する。ここで、電源ケーブル３０の他端のプラグの形状は、電源接続部２１ｄの接続コネクタの形状と同一であることが好ましい。   The power supply connecting portion 21 d is connected to the OA tap 40 and has, for example, a male connector, and supplies power supplied from the OA tap 40 to the power cable 30. Here, the shape of the plug at the other end of the power cable 30 is preferably the same as the shape of the connector of the power connection portion 21d.

なお、ＰＬＣ機器２０ｂにおけるデータ通信部２６は、操作スイッチ２３が操作された場合、所定の信号を電源接続部２１ｃ、２１ｄ間の配線に対し出力する。所定の信号は、電源接続部２１ｃから電源ケーブル３０に向けて送出される。また、電源接続部２１ｃに到来した所定の信号を受信した場合、データ通信部２６は、ＬＥＤ表示部２４を点灯あるいは点滅させる。   The data communication unit 26 in the PLC device 20b outputs a predetermined signal to the wiring between the power supply connection units 21c and 21d when the operation switch 23 is operated. The predetermined signal is sent out from the power supply connection portion 21 c toward the power cable 30. In addition, when receiving a predetermined signal arriving at the power supply connection unit 21c, the data communication unit 26 lights or blinks the LED display unit 24.

次に、電源供給システムの動作について説明する。図４は、電源供給システムの動作を表すフローチャートである。   Next, the operation of the power supply system will be described. FIG. 4 is a flowchart showing the operation of the power supply system.

ステップＳ１１において、ＰＬＣ機器２０ａにおける操作スイッチ２３が操作される（例えば押下される）。   In step S11, the operation switch 23 in the PLC device 20a is operated (for example, pressed).

ステップＳ１２において、ＰＬＣ機器２０ａにおけるデータ通信部２６は、操作スイッチ２３が操作されたことを検知し、所定の信号を電源接続部２１ｂから電源ケーブル３０に向け送出する。   In step S12, the data communication unit 26 in the PLC device 20a detects that the operation switch 23 has been operated, and sends a predetermined signal from the power supply connection unit 21b to the power cable 30.

ステップＳ１３において、ＰＬＣ機器２０ｂにおけるデータ通信部２６は、電源接続部２１ｃに所定の信号が到来したことを検知する。   In step S13, the data communication unit 26 in the PLC device 20b detects that a predetermined signal has arrived at the power supply connection unit 21c.

ステップＳ１４において、ＰＬＣ機器２０ｂにおけるデータ通信部２６は、ＬＥＤ表示部２４を点灯あるいは点滅させる。   In step S14, the data communication unit 26 in the PLC device 20b lights or blinks the LED display unit 24.

以上のように動作する電源供給システムによれば、電源ユニット１０に接続されたＰＬＣ機器２０ａにおける操作スイッチ２３を操作することで、対向するＯＡタップ４０上のＰＬＣ機器２０ｂにおけるＬＥＤ表示部２４が点灯あるいは点滅する。したがって、ＯＡタップ４０に接続される電源ケーブル３０の数が多い場合であっても、ＰＬＣ機器２０ｂのＬＥＤ表示部２４を目視することで、電源ユニット１０に対向するＯＡタップ４０上のコネクタを容易に特定することができる。この場合、電源供給システムとしては、既存の装置に対してＰＬＣ機器２０ａ、２０ｂを挿入して設置するだけであって、電源ユニット１０およびＯＡタップ４０には、何らの変更を必要としない。したがって、汎用性の高いシステムを構成することができる。   According to the power supply system that operates as described above, by operating the operation switch 23 in the PLC device 20a connected to the power supply unit 10, the LED display unit 24 in the PLC device 20b on the opposing OA tap 40 is turned on. Or it blinks. Therefore, even when the number of power cables 30 connected to the OA tap 40 is large, the connector on the OA tap 40 facing the power supply unit 10 can be easily viewed by visually checking the LED display unit 24 of the PLC device 20b. Can be specified. In this case, as a power supply system, only the PLC devices 20a and 20b are inserted and installed in an existing apparatus, and no changes are required for the power supply unit 10 and the OA tap 40. Therefore, a highly versatile system can be configured.

また、ＯＡタップ４０上のＰＬＣ機器２０ｂにおける操作スイッチ２３を操作することで、対向する電源ユニット１０に接続されたＰＬＣ機器２０ａにおけるＬＥＤ表示部２４が点灯あるいは点滅する。したがって、ＯＡタップ４０に接続されるサーバなどにおける電源ユニット１０を特定するのも容易である。   Further, by operating the operation switch 23 in the PLC device 20b on the OA tap 40, the LED display unit 24 in the PLC device 20a connected to the opposing power supply unit 10 is turned on or blinked. Therefore, it is easy to specify the power supply unit 10 in a server or the like connected to the OA tap 40.

なお、以上の説明では、電源ケーブル３０が二芯である場合を前提として説明したが、これに限定されず三芯以上であってもよい。この場合、ＰＬＣ機器２０ａ、２０ｂは、三芯以上の電源ケーブルに対応した接続構造を有し、互いに所定の信号を伝達可能なように構成されていれば良い。   In the above description, the case where the power cable 30 has two cores has been described. However, the present invention is not limited to this and may be three or more cores. In this case, the PLC devices 20a and 20b only need to have a connection structure corresponding to a power cable having three or more cores and be configured to transmit a predetermined signal to each other.

このような電源供給システムによれば、機器が大量に設置されているデータセンタでの、移設・撤去・保守点検などの作業時においてケーブルを特定する用途に好適である。   Such a power supply system is suitable for use in identifying a cable at the time of work such as relocation, removal, maintenance and inspection in a data center where a large amount of equipment is installed.

なお、上記の実施形態の一部または全部は、以下の付記のようにも記載されうるが、以下に限定されるものではない。   In addition, although a part or all of said embodiment may be described also as the following additional remarks, it is not limited to the following.
