［構成］
　図１は、本発明の第１実施形態における電力制御システム１を説明する図である。電力制御システム１は、配電線からの電力が供給されるコンセント３０と電気機器４０との間に設けられる電源タップ１０、および電源タップ１０と通信してコンセント３０から電気機器４０への通電を制御するための通信端末２０を有する。 <First Embodiment>
[Constitution]
FIG. 1 is a diagram illustrating a power control system 1 according to the first embodiment of the present invention. The power control system 1 controls the energization from the outlet 30 to the electrical device 40 by communicating with the power strip 10 provided between the electrical outlet 40 to which the power from the distribution line is supplied and the electrical device 40, and the power tap 10. A communication terminal 20 is provided.
　通信端末２０は、この例ではスマートフォンであるが、携帯電話、ＰＤＡ、ノートパソコンなど他の携帯端末であってもよいし、デスクトップパソコンなどの据置型端末であってもよい。 The communication terminal 20 is a smartphone in this example, but may be another portable terminal such as a mobile phone, a PDA, or a notebook personal computer, or may be a stationary terminal such as a desktop personal computer.
　電源タップ１０は、コンセント３０から電気機器４０への電力供給ラインとなるプラグ１０１、スイッチ１０２および接続部１０４を有する。この例では、電源タップ１０は、電気機器４０へ供給される電力を測定する電力測定部１０３を有する。また、電源タップ１０はスイッチ１０２の制御を行う構成として、通信部１１１、記憶部１１２、制御部１１３およびタイマ１１４を有する。 The power strip 10 includes a plug 101 that serves as a power supply line from the outlet 30 to the electrical device 40, a switch 102, and a connection unit 104. In this example, the power strip 10 includes a power measurement unit 103 that measures the power supplied to the electrical device 40. The power tap 10 includes a communication unit 111, a storage unit 112, a control unit 113, and a timer 114 as a configuration for controlling the switch 102.
　プラグ１０１は一般的な電気機器に設けられているプラグと同様な形状であり、コンセント３０に挿し込んで接続された状態でコンセント３０から電力の供給を受けるプラグ部である。スイッチ１０２は電流供給ラインに設けられた電磁リレーなどの継電器であり、制御部１１３の制御によって電気機器４０への通電の有無を切り替える切替部である。以下、スイッチ１０２が通電している状態を通電状態、通電していない状態を非通電状態という。接続部１０４は、コンセント３０と同様に一般的な電気機器のプラグが挿し込める形状であり、プラグ１０１に供給された電力を、挿し込まれて接続された電気機器４０に供給する。なお、接続部１０４は、コンセント３０とは別の規格のプラグが挿し込める形状であってもよい。 The plug 101 has a shape similar to that of a plug provided in a general electric device, and is a plug portion that receives power supply from the outlet 30 while being inserted into the outlet 30 and connected thereto. The switch 102 is a relay such as an electromagnetic relay provided in the current supply line, and is a switching unit that switches whether the electric device 40 is energized or not under the control of the control unit 113. Hereinafter, a state where the switch 102 is energized is referred to as an energized state, and a state where the switch 102 is not energized is referred to as a non-energized state. The connection unit 104 has a shape in which a plug of a general electric device can be inserted, similarly to the outlet 30, and supplies the electric power supplied to the plug 101 to the electric device 40 that is inserted and connected. The connection unit 104 may have a shape in which a plug having a standard different from that of the outlet 30 can be inserted.
　電力測定部１０３は電気機器４０へ供給した電力を測定して、測定結果を制御部１１３に出力する。 The power measuring unit 103 measures the power supplied to the electric device 40 and outputs the measurement result to the control unit 113.
　図２は、本発明の第１実施形態における電源タップ１０の外観図である。図２（ｂ）は図２（ａ）に示す矢印Ｆの方向から見た図である。電源タップ１０は、この例では、略直方体の形状であり、プラグ１０１が設けられた面と接続部１０４が設けられた面とは対向している。 FIG. 2 is an external view of the power strip 10 according to the first embodiment of the present invention. FIG. 2B is a view as seen from the direction of the arrow F shown in FIG. In this example, the power tap 10 has a substantially rectangular parallelepiped shape, and the surface on which the plug 101 is provided and the surface on which the connection portion 104 is provided are opposed to each other.
　図１に戻って説明を続ける。通信部１１１は通信端末２０と通信して情報の送受信を行う。通信部１１１は、この例では無線ＬＡＮ（Local Area Network）により通信端末２０と通信するものとするが、Ｂｌｕｅｔｏｏｔｈ（登録商標）などの近距離無線通信、携帯電話などで用いられる通信回線などを用いてもよい。また、無線通信に限らず、有線通信であってもよい。有線通信の場合には、ＰＬＣ（Power Line Communication）などの電力線搬送通信を用いてもよい。 Referring back to FIG. The communication unit 111 communicates with the communication terminal 20 to transmit / receive information. In this example, the communication unit 111 communicates with the communication terminal 20 via a wireless LAN (Local Area Network), but uses a short-distance wireless communication such as Bluetooth (registered trademark), a communication line used in a mobile phone, or the like. May be. Moreover, not only wireless communication but wired communication may be used. In the case of wired communication, power line carrier communication such as PLC (Power Line Communication) may be used.
　記憶部１１２は不揮発性メモリであり、通電制限時間を示す情報を記憶する。通電制限時間とは、スイッチ１０２により通電が開始されてから停止するまでの時間である。この例では、通電制限時間は予め決められている。タイマ１１４は制御部１１３の制御により所定の周期（クロック信号の周期など）でカウンタの値を増加（カウントアップ）し、カウンタの値を制御部１１３に出力する。カウンタの値はカウントアップを開始してからの経過時間に相当する。 The storage unit 112 is a nonvolatile memory and stores information indicating the energization limit time. The energization limit time is the time from when energization is started by the switch 102 until it is stopped. In this example, the energization limit time is predetermined. The timer 114 increases (counts up) the counter value at a predetermined period (such as a clock signal period) under the control of the control unit 113, and outputs the counter value to the control unit 113. The counter value corresponds to the elapsed time from the start of counting up.
　制御部１１３は演算処理装置であり、通信端末２０からの指示に応じて電力制御処理を行う。電力制御処理については別途詳述するが、非通電状態において通信端末２０から通電開始要求を受け付けることにより通電状態に切り替え、通電制限時間が経過すると非通電状態に切り替える処理である。 The control unit 113 is an arithmetic processing unit, and performs power control processing according to an instruction from the communication terminal 20. The power control process will be described in detail separately, and is a process of switching to the energized state by accepting an energization start request from the communication terminal 20 in the non-energized state, and switching to the non-energized state when the energization limit time has elapsed.
　通信端末２０は、制御部２０１、タッチパネル２０２および通信部２０３を有する。制御部２０１は演算処理装置であり、図示しない記憶部に記憶されたアプリケーションプログラムを実行することにより、通信端末２０を電源タップ１０における電力制御処理を実行させるための指示を行う装置として機能させる。通信部２０３は電源タップ１０と通信して情報の送受信を行う。この例では、電源タップ１０に接続された電気機器４０へ通電を開始させるための通電開始要求が通信端末２０から電源タップ１０へ送信される。タッチパネル２０２は、制御部２０１の制御により画像の表示を行う画面、および画面へのユーザの操作（画面へのタッチなど）を検出して制御部２０１に操作信号を出力するタッチセンサを有する。 The communication terminal 20 includes a control unit 201, a touch panel 202, and a communication unit 203. The control unit 201 is an arithmetic processing device, and functions as a device for instructing the communication terminal 20 to execute power control processing in the power strip 10 by executing an application program stored in a storage unit (not shown). The communication unit 203 communicates with the power tap 10 to transmit / receive information. In this example, an energization start request for starting energization of the electrical device 40 connected to the power tap 10 is transmitted from the communication terminal 20 to the power tap 10. The touch panel 202 includes a screen that displays an image under the control of the control unit 201, and a touch sensor that detects a user operation (such as touching the screen) on the screen and outputs an operation signal to the control unit 201.
　図３は、本発明の第１実施形態における通信端末２０での表示例を示す図である。タッチパネル２０２には、図３に示すように、電源タップ１０に対して通電開始要求を送信するためのボタン２１１、通電制限時間の表示領域２１２、および電力関連情報の表示領域２１３などを含む画像が表示される。 FIG. 3 is a diagram showing a display example on the communication terminal 20 in the first embodiment of the present invention. As shown in FIG. 3, the touch panel 202 includes an image including a button 211 for transmitting an energization start request to the power tap 10, an energization time limit display area 212, and a power related information display area 213. Is displayed.
　ボタン２１１の表示領域にユーザがタッチすると、制御部２０１は、通信部２０３を介して、電源タップ１０に対して通電開始要求を送信する。制御部２０１は、予め記憶部１１２に記憶されている通電制限時間を電源タップ１０から受信し、表示領域２１２に表示させる。また、制御部２０１は、電力測定部１０３により測定された電力の値を電源タップ１０から受信し、表示領域２１３に表示させる。電力量、料金については、所定の計算式において電力から算出された値として表示される。なお、表示領域２１２、２１３については存在しなくてもよい。以上が電力制御システム１の構成についての説明である。 When the user touches the display area of the button 211, the control unit 201 transmits an energization start request to the power tap 10 via the communication unit 203. The control unit 201 receives the energization time limit stored in advance in the storage unit 112 from the power tap 10 and causes the display area 212 to display it. In addition, the control unit 201 receives the power value measured by the power measurement unit 103 from the power tap 10 and causes the display area 213 to display the power value. About electric energy and a charge, it displays as a value calculated from electric power in the predetermined | prescribed calculation formula. Note that the display areas 212 and 213 may not exist. The above is the description of the configuration of the power control system 1.
［電力制御処理］
　続いて、電源タップ１０における電力制御処理について説明する。図４は、本発明の第１実施形態における通電制御処理を説明するフローチャートである。電源タップ１０は、プラグ１０１がコンセント３０に挿し込まれ、接続部１０４に電気機器４０のプラグが挿し込まれることにより、電気機器４０へ電力供給が可能な状態になると、電力制御処理を開始する。電力制御処理が開始されると、制御部１１３は通信端末２０からの通電開始要求の受信を待つ（ステップＳ１０１；Ｎｏ）。 [Power control processing]
Next, power control processing in the power tap 10 will be described. FIG. 4 is a flowchart for explaining energization control processing in the first embodiment of the present invention. When the plug 101 is inserted into the outlet 30 and the plug of the electric device 40 is inserted into the connecting portion 104, the power strip 10 starts the power control process when power can be supplied to the electric device 40. . When the power control process is started, the control unit 113 waits for reception of an energization start request from the communication terminal 20 (step S101; No).
　ユーザが通信端末２０を操作（タッチパネル２０２に表示されているボタン２１１をタッチ）して通電開始要求が送信され、電源タップ１０において通電開始要求を受信する（ステップＳ１０１；Ｙｅｓ）と、制御部１１３は記憶部１１２に記憶された通電制限時間を読み出して、タイマ１１４から出力される値と比較するための時間として設定する（ステップＳ１０２）。制御部１１３はスイッチ１０２を制御して非通電状態から通電状態に切り替えて電気機器４０への通電を開始する（ステップＳ１１１）。制御部１１３はタイマ１１４を起動し、カウンタをリセットする（ステップＳ１１２）。なお、ステップＳ１０２、Ｓ１１１、Ｓ１１２の処理については、それぞれ順番が入れ替わってもよい。 When the user operates the communication terminal 20 (touches the button 211 displayed on the touch panel 202), an energization start request is transmitted, and the energization start request is received at the power tap 10 (step S101; Yes), the control unit 113. Reads out the energization limit time stored in the storage unit 112 and sets it as a time for comparison with the value output from the timer 114 (step S102). The control unit 113 controls the switch 102 to switch from the non-energized state to the energized state and starts energizing the electrical device 40 (step S111). The control unit 113 activates the timer 114 and resets the counter (step S112). Note that the order of the processes of steps S102, S111, and S112 may be changed.
　タイマ１１４はカウンタの値を増加（カウントアップ）させて制御部１１３に出力する（ステップＳ１１３）。制御部１１３はタイマ１１４から出力されたカウンタの値と設定した時間（通電制限時間）とを比較する。上述したとおり、このカウンタの値は通電開始からの経過時間に相当する。カウンタの値に相当する経過時間が通電制限時間に到達した場合（ステップＳ１１４；Ｎｏ）には、ステップＳ１１３の処理に戻って、その経過時間が通電制限時間に到達するまで、ステップＳ１１３およびステップＳ１１４の処理を繰り返す。この繰り返しをしている間において、制御部１１３は通信部１１１を介して、電力測定部１０３で測定された電力を示す情報を通信端末２０に送信する。通信端末２０においては、この情報に基づいてタッチパネル２０２の表示領域２１３に電力関連表示が表示される。 The timer 114 increases (counts up) the value of the counter and outputs it to the control unit 113 (step S113). The control unit 113 compares the counter value output from the timer 114 with the set time (energization limit time). As described above, the value of this counter corresponds to the elapsed time from the start of energization. If the elapsed time corresponding to the counter value has reached the energization limit time (step S114; No), the process returns to step S113, and step S113 and step S114 until the elapsed time reaches the energization limit time. Repeat the process. During this repetition, the control unit 113 transmits information indicating the power measured by the power measurement unit 103 to the communication terminal 20 via the communication unit 111. In the communication terminal 20, the power related display is displayed in the display area 213 of the touch panel 202 based on this information.
　一方、経過時間が通電制限時間に到達した場合（ステップＳ１１４；Ｙｅｓ）には、制御部１１３はスイッチ１０２を制御して、通電状態から非通電状態に切り替えて電気機器４０への通電を停止させ（ステップＳ１１５）、再び通信端末２０からの通電開始要求の受信を待つ（ステップＳ１０１；Ｎｏ）。 On the other hand, when the elapsed time reaches the energization limit time (step S114; Yes), the control unit 113 controls the switch 102 to switch from the energized state to the non-energized state to stop energization of the electrical device 40. (Step S115), it waits for the receipt of the energization start request from the communication terminal 20 again (Step S101; No).
　このように、本発明の第１実施形態における電力制御システム１においては、電源タップ１０がコンセント３０に挿し込み可能なプラグ１０１を有している。そのため、予め通電制御を行うための設備が設けられていないコンセント３０においても、電源タップ１０をそのコンセント３０に挿し込んで、電気機器４０との間に設けることで、通信端末２０を用いた通電制御をすることができる。 Thus, in the power control system 1 according to the first embodiment of the present invention, the power strip 10 has the plug 101 that can be inserted into the outlet 30. Therefore, even in an outlet 30 that is not provided with a facility for performing energization control in advance, the power supply tap 10 is inserted into the outlet 30 and provided between the electric device 40 and the energization using the communication terminal 20. You can control.
＜第２実施形態＞
　第２実施形態における電力制御システム１は、第１実施形態の構成において通電制限時間を変更することができるように構成されている。通信端末２０へのユーザの操作により通電制限時間の変更指示を入力すると、通電制限時間の変更指示が電源タップ１０に送信され、図３に示す表示領域２１２の時間が変更後の通電制限時間に変更される。この例では、電源タップ１０が通電状態である場合には、ユーザによって通信端末２０に通電制限時間の変更指示が入力されると、通信端末２０から電源タップ１０に変更指示が送信される。一方、電源タップ１０が非通電状態である場合には、通電制限時間の変更指示がユーザによって入力されたときではなく、通電開始要求が電源タップ１０に送信されるときに、通電制限時間の変更指示もあわせて送信されるものとする。なお、非通電状態においては、通電制限時間の変更指示が入力されたときに、その変更指示が電源タップ１０に送信され、記憶部１１２に記憶された通電制限時間が変更されるようにしてもよい。 <Second Embodiment>
The power control system 1 in the second embodiment is configured such that the energization time limit can be changed in the configuration of the first embodiment. When an instruction to change the energization limit time is input by a user operation on the communication terminal 20, an instruction to change the energization limit time is transmitted to the power tap 10, and the time of the display area 212 shown in FIG. Be changed. In this example, when the power tap 10 is in the energized state, when the user inputs an instruction to change the energization limit time to the communication terminal 20, the change instruction is transmitted from the communication terminal 20 to the power tap 10. On the other hand, when the power tap 10 is in a non-energized state, the change in the energization limit time is not performed when an energization start request is transmitted to the power tap 10, not when an instruction to change the energization limit time is input by the user. Instructions shall be sent together. In the non-energized state, when an instruction to change the energization limit time is input, the change instruction is transmitted to the power tap 10 so that the energization limit time stored in the storage unit 112 is changed. Good.
　図５は、本発明の第２実施形態における通電制御処理を説明するフローチャートである。第２実施形態での通電制御処理のうち、第１実施形態と同じ処理を行う部分については、その説明を省略する。なお、第１実施形態と同じ処理を行う部分については同じ符号を付してある。 FIG. 5 is a flowchart for explaining energization control processing in the second embodiment of the present invention. Of the energization control process in the second embodiment, the description of the part that performs the same process as in the first embodiment is omitted. In addition, the same code | symbol is attached | subjected about the part which performs the same process as 1st Embodiment.
　通電開始要求を受信する（ステップＳ１０１；Ｙｅｓ）と、制御部１１３は通電制限時間の変更指示が通電開始要求とともに送信されているか否かを判定する（ステップＳ１２１）。通電制限時間の変更指示が送信されている場合（ステップＳ１２１；Ｙｅｓ）には、制御部１１３は記憶部１１２に記憶された通電制限時間を変更指示にしたがって変更する。 When receiving the energization start request (step S101; Yes), the control unit 113 determines whether or not an instruction to change the energization limit time is transmitted together with the energization start request (step S121). When an instruction to change the energization limit time has been transmitted (step S121; Yes), the control unit 113 changes the energization limit time stored in the storage unit 112 in accordance with the change instruction.
　通電制限時間の変更指示が送信されていない場合（ステップＳ１２１；Ｎｏ）、または通電制限時間を変更した場合（ステップＳ１２２）には、制御部１１３は記憶部１１２に記憶された通電制限時間を読み出して、タイマ１１４から出力される値と比較するための時間として設定する（ステップＳ１０２）。以降の処理は、第１実施形態と同様であるため説明を省略するが、第１実施形態とはステップＳ１１３とステップＳ１１４との間において異なる処理（ステップＳ１３１、ステップＳ１３２）が含まれるため、その部分のみ説明する。 When the instruction to change the energization limit time is not transmitted (step S121; No), or when the energization limit time is changed (step S122), the control unit 113 reads the energization limit time stored in the storage unit 112. Thus, it is set as a time for comparison with the value output from the timer 114 (step S102). Subsequent processing is the same as that of the first embodiment, and thus description thereof is omitted. However, since processing different from that of the first embodiment between step S113 and step S114 (step S131 and step S132) is included, Only the part is explained.
　ステップＳ１１３からステップＳ１１４の処理を繰り返す間に通信端末２０から通電制限時間の変更指示が送信され、電源タップ１０において受信した場合（ステップＳ１３１；Ｙｅｓ）には、制御部１１３はステップＳ１０２の処理において設定した時間を、変更指示にしたがって変更する（ステップＳ１３２）。この処理により、ステップＳ１１４においてカウンタの値に相当する経過時間との比較対象となる通電制限時間も変更される。これにより、通電開始後であっても通電制限時間を短縮したり延長したりすることができる。ここで、記憶部１１２に記憶された通電制限時間については、変更指示にしたがって変更されるようにしてもよいし、もとの時間のまま変更されないようにしてもよい。一方、電源タップ１０において通電制限時間の変更指示を受信していない場合（ステップＳ１３１；Ｎｏ）には、制御部１１３はステップＳ１１４の処理を行う。 When the communication terminal 20 transmits an instruction to change the energization limit time while repeating the processing from step S113 to step S114 and receives it at the power tap 10 (step S131; Yes), the control unit 113 performs the processing in step S102. The set time is changed according to the change instruction (step S132). By this process, the energization limit time to be compared with the elapsed time corresponding to the counter value in step S114 is also changed. Thereby, even after the start of energization, the energization limit time can be shortened or extended. Here, the energization time limit stored in the storage unit 112 may be changed according to the change instruction, or may not be changed as it is. On the other hand, when the power tap 10 has not received an instruction to change the energization limit time (step S131; No), the control unit 113 performs the process of step S114.
　このように、本発明の第２実施形態における電力制御システム１においては、通信端末２０へのユーザの操作により、通電制限時間を変更することができる。なお、第２実施形態において、ステップＳ１２１およびステップＳ１２２の処理、またはステップＳ１３１およびステップＳ１３２の処理のうち、いずれかの処理が実施されなくてもよい。 Thus, in the power control system 1 according to the second embodiment of the present invention, the energization time limit can be changed by a user operation on the communication terminal 20. In the second embodiment, any one of the processes in steps S121 and S122 or the processes in steps S131 and S132 may not be performed.

　図６は、本発明の第３実施形態における通電制御処理を説明するフローチャートである。第３実施形態での通電制御処理のうち、第１実施形態と同じ処理を行う部分については、その説明を省略する。なお、第１実施形態と同じ処理を行う部分については同じ符号を付してある。第３実施形態では、第１実施形態とはステップＳ１１３とステップＳ１１４との間において異なる処理（ステップＳ１４１、ステップＳ１４２）が含まれるため、その部分のみ説明する。 FIG. 6 is a flowchart for explaining energization control processing in the third embodiment of the present invention. Of the energization control process in the third embodiment, the description of the part that performs the same process as in the first embodiment is omitted. In addition, the same code | symbol is attached | subjected about the part which performs the same process as 1st Embodiment. In 3rd Embodiment, since the process (step S141, step S142) different between 1st Embodiment between step S113 and step S114 is included, only the part is demonstrated.
　ステップＳ１１３からステップＳ１１４の処理を繰り返す間において、制御部１１３はタイマ１１４から出力されたカウンタの値と通知時間とを比較する（ステップＳ１４１）。この通知時間は、ステップＳ１０２において設定した時間（通電制限時間）よりも短くなるように設定され、通電制限時間より一定時間（例えば１分間）短い時間として設定される。なお、通知時間は、通電制限時間の所定割合（例えば９０％）として設定されてもよい。 While the processing from step S113 to step S114 is repeated, the control unit 113 compares the counter value output from the timer 114 with the notification time (step S141). This notification time is set to be shorter than the time set in step S102 (energization limit time), and is set as a time shorter than the power supply limit time by a certain time (for example, 1 minute). The notification time may be set as a predetermined ratio (for example, 90%) of the energization limit time.
　カウンタの値に相当する経過時間が通知時間に到達していない場合（ステップＳ１４１；Ｎｏ）には、制御部１１３はステップＳ１１４の処理に進む。一方、その経過時間が通知時間に到達した場合（ステップＳ１４１；Ｙｅｓ）には、制御部１１３は通信部１１１を介して、通信端末２０に対して通電を停止する旨の通知を行い（ステップＳ１４２）、ステップＳ１１４の処理に進む。この後、経過時間が通電制限時間に達するまで、ステップＳ１１３からステップＳ１１４の処理を繰り返すことになる。なお、この繰り返しの処理において、ステップＳ１４２で通信端末２０に対しての通知を一度行った後については、ステップＳ１４１およびステップＳ１４２の処理は省略される。 If the elapsed time corresponding to the counter value has not reached the notification time (step S141; No), the control unit 113 proceeds to the process of step S114. On the other hand, when the elapsed time reaches the notification time (step S141; Yes), the control unit 113 notifies the communication terminal 20 that the energization is stopped via the communication unit 111 (step S142). ), The process proceeds to step S114. Thereafter, the processing from step S113 to step S114 is repeated until the elapsed time reaches the energization limit time. In this repeated process, after the notification to the communication terminal 20 is performed once in step S142, the processes in steps S141 and S142 are omitted.

In addition, the same code | symbol is attached | subjected about the part which performs the same process as 1st, 2nd, 3rd embodiment.
　ステップＳ１３１およびステップＳ１３２の処理と、ステップＳ１４１およびステップＳ１４２の処理とは、いずれの処理が先に行われてもよい。また、ステップＳ１４２において通信端末２０に対して通電停止の通知がなされた後に、ステップＳ１３２において通電制限時間が変更されると、再び経過時間が通知時間に到達する場合もある。その場合には、ステップＳ１４２において改めて通信端末２０に通電停止の通知がなされるようにしてもよい。 Any of the processes of step S131 and step S132 and the processes of step S141 and step S142 may be performed first. In addition, when the energization limit time is changed in step S132 after the communication terminal 20 is notified of the communication terminal 20 in step S142, the elapsed time may reach the notification time again. In that case, in step S142, the communication terminal 20 may be notified of energization stop again.

The touch panel 202 of the communication terminal 20A is provided with a pop-up menu 214 for designating one of the plurality of power taps 10A. In the pop-up menu 214, when the user performs a predetermined operation, a list of power strips 10A that can communicate with the mobile terminal 20A is displayed, and any one of the power strips 10A can be designated. In the example shown in FIG. 9, the power strip 10A-2 corresponding to “No. 2” is designated. When the user inputs an instruction to transmit an energization start request in this state, the energization start request is transmitted to the power strip 10A-2, and the power control process described above is performed in the power tap 10A-2. As described above, the present invention can also be realized as a power control system 1A in which a plurality of power strips 10A exist for one communication terminal 20.
＜第６実施形態＞

It is good also as a structure which transmits an energization start request | requirement by type | mold communication. At this time, in transmission of the energization start request, the communication terminal 20A transmits identification information of the power tap 10A to be energized in association with the energization start request.
　図１０は、本発明の第６実施形態における通電制御処理を説明するフローチャートである。第６実施形態での通電制御処理のうち、第１実施形態と同じ処理を行う部分については、その説明を省略する。なお、第１実施形態と同じ処理を行う部分については同じ符号を付してある。第６実施形態では、第１実施形態とはステップＳ１０１とステップＳ１０２との間において異なる処理（ステップＳ１５１）が含まれるため、その部分のみ説明する。 FIG. 10 is a flowchart for explaining energization control processing in the sixth embodiment of the present invention. Of the energization control process in the sixth embodiment, the description of the part that performs the same process as in the first embodiment is omitted. In addition, the same code | symbol is attached | subjected about the part which performs the same process as 1st Embodiment. In the sixth embodiment, processing (step S151) that differs between step S101 and step S102 from the first embodiment is included, so only that part will be described.
　通電開始要求を受信する（ステップＳ１０１；Ｙｅｓ）と、制御部１１３は通電開始要求に対応付けて送信されてくる識別情報に基づいて、通電開始要求が自装置を指定して送信されたものであるか否かを判定する（ステップＳ１５１）。ここでは、制御部１１３は、送信されてきた識別情報が自装置に割り当てられている識別情報と一致する場合に、自装置が指定されたものと判定する。自装置が指定されていた場合（ステップＳ１５１；Ｙｅｓ）には、制御部１１３は、ステップＳ１０２以降の処理を行う。一方、自装置が指定されていない場合（ステップＳ１５１；Ｎｏ）には、制御部１１３は、ステップＳ１０１の処理に戻って次の通電開始要求の受信を待つことになる。この例では電力制御処理は第１実施形態の例を適用して説明したが、第２、第３、第４実施形態の例を適用することもできる。 When the energization start request is received (step S101; Yes), the control unit 113 transmits the energization start request specifying its own device based on the identification information transmitted in association with the energization start request. It is determined whether or not there is (step S151). Here, the control unit 113 determines that the own apparatus is designated when the transmitted identification information matches the identification information assigned to the own apparatus. When the own apparatus is designated (step S151; Yes), the control unit 113 performs the processing after step S102. On the other hand, when the own apparatus is not specified (step S151; No), the control unit 113 returns to the process of step S101 and waits for reception of the next energization start request. In this example, the power control process has been described by applying the example of the first embodiment, but the examples of the second, third, and fourth embodiments can also be applied.
　第５実施形態の図９で説明したように、通信端末２０Ａにおいて電源タップ１０Ａ－２を指定して通電開始要求が送信された場合には、電源タップ１０Ａ－２のみが通電を開始することになる。なお、通信端末２０Ａにおいて、ユーザが複数の電源タップ１０Ａが指定できるようになっていてもよい。この場合には、通信開始要求に対応付けて複数の識別情報が送信されればよい。そして、制御部１１３はステップＳ１５１の処理において、自装置を示す識別情報が含まれていれば、自装置が指定されていると判定すればよい。このようにすると、通電を開始させる複数の電源タップ１０Ａをまとめて指定することができる。 As described with reference to FIG. 9 of the fifth embodiment, when the communication terminal 20A designates the power strip 10A-2 and the energization start request is transmitted, only the power strip 10A-2 starts energization. Become. In communication terminal 20A, a user may be able to specify a plurality of power strips 10A. In this case, a plurality of identification information may be transmitted in association with the communication start request. And control part 113 should just judge with a self-apparatus having been specified if the discernment information which shows a self-apparatus is included in processing of Step S151. In this way, it is possible to collectively specify a plurality of power strips 10A for starting energization.
