Description

発明の詳細な説明Detailed Description of the Invention

本発明は、時刻情報を送信する配電盤に関する。  The present invention relates to a switchboard that transmits time information.

家庭用の電気器具ないし電気機器、いわゆる家電製品の時刻合せ、すなわち家電製品が具備している時計の時刻を合わせるのに、時刻情報の伝送線として電力線を利用する技術が知られている。例えば、特開２００３−１０６６２５号公報には、次のような技術が示されている。
電力線搬送機能を備えた電気器具であって、カレンダーや現在時刻等を設定する設定手段を有した電気器具を備えた制御システムにおいて、標準電波を自動受信する受信手段を搭載した制御装置を備え、この制御装置が商用電源に接続され、電力線搬送機能を備えた電気器具の前記設定手段に対し、カレンダーや現在時刻等を設定し、或いは設定手段に設定されたカレンダーや現在時刻等を修正することを特徴とする制御システム、に関する技術である。
これによれば、ある家電製品（電気器具）の時刻合わせをするためには、制御装置には、常にＡＣ電源を供給しておかなければならない。すなわち、該制御装置の電源プラグをＡＣ電源供給部（いわゆるコンセント）差しっぱなしにしておかなければならない。どうしてかと言うと、ある家電製品例えばビデオデッキ、いわゆるＶＴＲを使おうと思って、そのＶＴＲの電源プラグをコンセントに差し込んでも、時刻情報の送信元である該制御装置の電源プラグがコンセントに差し込んでなければ、使用するＶＴＲは、電力線（ＡＣ電源伝送線）を介して該制御装置から時刻情報を受け取れず、ＶＴＲの時刻合わせができないからである。
従って、従来の時刻合せシステムは、時刻情報の送信元である制御装置が、常時、余分な（待機）電力を消費することになる。2. Description of the Related Art There is known a technique that uses a power line as a transmission line for time information in order to synchronize the time of household appliances or electric appliances, so-called home appliances, that is, to adjust the time of a clock included in home appliances. For example, Japanese Patent Laid-Open No. 2003-106625 discloses the following technique.
An electric appliance having a power line carrying function, and a control system including an electric appliance having setting means for setting a calendar, a current time, etc., and a control device equipped with a receiving means for automatically receiving a standard radio wave, The control device is connected to a commercial power source, and the calendar, the current time, etc. are set to the setting means of the appliance having the power line carrying function, or the calendar, the current time, etc. set in the setting means are corrected. It is the technique regarding the control system characterized by this.
According to this, in order to set the time of a certain home appliance (electric appliance), it is necessary to always supply AC power to the control device. That is, the AC power supply unit (so-called outlet) must be left plugged in the control device. After all, if you want to use a certain home appliance such as a video deck, so-called VTR, and plug the power plug of the VTR into an outlet, the power plug of the control device that is the source of time information must be plugged into the outlet. This is because the VTR to be used cannot receive time information from the control device via the power line (AC power transmission line) and cannot adjust the time of the VTR.
Therefore, in the conventional time adjustment system, the control device that is the transmission source of the time information always consumes extra (standby) power.

発明が解決しようとする課題Problems to be solved by the invention

本発明に係る時刻情報を送信する配電盤は、上記した従来の技術が有する問題点に鑑み成されたものであり、次の課題を解決することを目的とする。
電力線を利用する時刻合せシステムにおいて、時刻情報を送信する送信元、すなわち時刻合せシステムの制御部が電力をほとんど消費しない、時刻情報を送信する配電盤を提供する。The switchboard for transmitting time information according to the present invention is made in view of the problems of the above-described conventional technology, and aims to solve the following problems.
In a time adjustment system using a power line, a distribution board for transmitting time information in which a transmission source for transmitting time information, that is, a control unit of the time adjustment system consumes little power is provided.

課題を解決するための手段Means for solving the problem

上記課題を解決するための本発明は、請求項１に記載されたとおりの時刻情報を送信する配電盤であり、電力の供給を受ける外線が配線されているとともに、給電用の電力線を収容する配電盤に、前記電力線へ時刻情報を送信する時刻情報送信手段を設け、前記時刻情報は、前記時刻情報送信手段の内部で生成されて前記電力線に送信されるか、もしくは前記外線を介して前記時刻情報送信手段に供給されて前記電力線に送信されるか、であり、電力消費量変化検出手段を具備し、その電力消費量の変化が所定レベルを超えると、前記時刻情報送信手段が前記電力線へ時刻情報を送信する、構成である。The present invention for solving the above-mentioned problems is a switchboard for transmitting time information as described in claim 1, wherein an external line for receiving power supply is wired and a switchboard for accommodating a power supply power line Provided with time information transmitting means for transmitting time information to the power line, wherein the time information is generated inside the time information transmitting means and transmitted to the power line, or the time information is transmitted via the external line. Is supplied to the transmission means and transmitted to the power line, and includes power consumption change detection means, and when the change in the power consumption exceeds a predetermined level, the time information transmission means sends a time to the power line. This is a configuration for transmitting information .

図１は、本発明に係る時刻情報を送信する配電盤の実施の一形態を示すブロック図である。
配電盤１は、送電所１０から電力の供給を受けるべく外線７が引き込んである。すなわち、ここでいう外線７は、配電盤１に電力を送り込むための電線ないし送電線である。
配電盤１は、従来技術同様、何系統かの電力線３、少なくとも１系統の電力線が収容してあり、電力線３の末端は、いわゆるコンセントであり、ここでは、２系統の電力線３と、コンセントＡ４ａ、コンセントＢ４ｂ及びコンセントＣ４ｃの三つのコンセントを想定する。もちろん、本発明を実施するのに、電力線３の系統数及びコンセントの数に制限はない。それらは、当業者が適宜設計選択する事項である。
各コンセントＡ〜Ｃ（４ａ〜４ｃ）には、それぞれ単数または複数の電源プラグを差し込むことができる。便宜上、本明細書では、１つのコンセントには、１つの電源プラグを差し込むものとして説明する。
ここでは、コンセントＡ４ａには、電気機器Ａ６ａが備える電源プラグ４ａを、コンセントＡ４ｂには、電気機器Ｂ６ｂが備える電源プラグ４ｂを、コンセントＣ４ｃには、電気機器Ａ６ｃが備える電源プラグ４ｃを、それぞれ差し込んで、配電盤１及び電力線３を介して電力の供給を受けるものとする。FIG. 1 is a block diagram showing an embodiment of a switchboard for transmitting time information according to the present invention.
The distribution board 1 has an outside line 7 drawn in to receive power from the power transmission station 10. That is, the external line 7 here is an electric wire or a power transmission line for sending electric power to the switchboard 1.
As in the prior art, the switchboard 1 accommodates several power lines 3 and at least one power line. The terminal of the power line 3 is a so-called outlet. Here, the two power lines 3 and the outlet A4a, Assume three outlets, outlet B4b and outlet C4c. Of course, there are no restrictions on the number of power lines 3 and the number of outlets for carrying out the present invention. These are matters that are appropriately selected by those skilled in the art.
One or a plurality of power plugs can be inserted into each of the outlets A to C (4a to 4c). For the sake of convenience, this specification will be described assuming that one power plug is inserted into one outlet.
Here, the power plug 4a included in the electric device A6a is inserted into the outlet A4a, the power plug 4b included in the electric device B6b is inserted into the outlet A4b, and the power plug 4c included in the electric device A6c is inserted into the outlet C4c. Thus, it is assumed that power is supplied through the switchboard 1 and the power line 3.

配電盤１には、時刻情報送信手段２が設けてあり、時刻情報送信手段２には、時計２ａを具備させることができる。なお、本明細書でいう時計というのは、時刻情報を信号として出力できればいいのであって、時刻そのものを数字や針で表示する必要は必ずしもない。
また、時刻情報送信手段２は、自身の内部で（例、時計２で）生成する時刻情報、もしくは外部から受信する時刻情報を電力線３に送出する機能を有する。具体的には、電力信号に時刻情報をいわゆる重畳ないし変調して電力線３へ送出する。電力信号とその他の信号の重畳による伝送は、明白な周知技術であるので、本発明を実施しようとする者は、その点については任意の方法、方式を用いればよい。
配電盤１に設けられた時刻情報送信手段２は、常時、または定期的（一定時間間隔毎）に、時刻情報を電力線３を介して各コンセントへ送信し、時刻情報送信手段２が送信する時刻情報の流れ８は、図１で示されるように、コンセント（４ａ、４ｂ）に電源プラグ（５ａ、５ｃ）を差し込んでいる電機機器にまで到達する。電気機器Ａ６ａ及び電気機器Ｃ６ｃは、所望なら、すなわち受信する電力信号から時刻情報を分離ないし復調するように作られているものであるなら、時刻合わせをすることができる。
電機機器Ａ〜Ｃ（６ａ〜６ｃ）を使用しないときは、各電源プラグ（５ａ〜５ｃ）を各コンセント（４ａ〜４ｃ）から外しておき、電気機器を使用するべく電源プラグ（５ａ〜５ｃ）をコンセント（４ａ〜４ｃ）差し込めば、それだけで、時刻情報を受信でき、時刻合わせをし得ることが理解され得よう。つまり、テレビやＶＴＲや音響機器などの電気機器（家電製品）を使用しないときは、その電源プラグをコンセントから外しておいても何の不都合もないわけであるから、本発明を実施すれば、節電を図ることができる。そして、そのようにして節電を図った場合でも、その電気機器を実際に使うときは、既に時刻合わせができているので、ユーザが一々時刻合わせをする必要がなく、快適にその電気機器を使用することができる。もちろん、時刻合わせのための制御装置（例、ホームサーバ、エアコンなど）にＡＣ電源を常時供給しておく必要もない。そのような無駄な電力消費をも抑制できる。The switchboard 1 is provided with time information transmission means 2, and the time information transmission means 2 can be provided with a clock 2a. Note that the timepiece in this specification only needs to be able to output time information as a signal, and it is not always necessary to display the time itself with numerals or hands.
Further, the time information transmission unit 2 has a function of transmitting to the power line 3 time information generated inside itself (for example, with the clock 2) or time information received from the outside. Specifically, time information is so-called superimposed or modulated on the power signal and sent to the power line 3. Since transmission by superimposing a power signal and other signals is an obvious well-known technique, a person who intends to implement the present invention may use any method and method in this regard.
The time information transmitting means 2 provided in the switchboard 1 transmits time information to each outlet via the power line 3 at all times or regularly (at regular time intervals), and the time information transmitted by the time information transmitting means 2 As shown in FIG. 1, the flow 8 reaches the electrical equipment in which the power plugs (5a, 5c) are inserted into the outlets (4a, 4b). The electric device A6a and the electric device C6c can adjust the time if desired, that is, if the electric device A6a and the electric device C6c are designed to separate or demodulate time information from the received power signal.
When the electric devices A to C (6a to 6c) are not used, the power plugs (5a to 5c) are removed from the outlets (4a to 4c), and the power plugs (5a to 5c) are used to use the electric devices. It will be understood that the time information can be received and the time can be adjusted by simply plugging in the outlet (4a to 4c). In other words, when not using electrical equipment (home appliances) such as TVs, VTRs and audio equipment, there is no inconvenience even if the power plug is removed from the outlet. Power can be saved. Even when power is saved in this way, when you actually use the electrical device, the time has already been set, so there is no need for the user to set the time one by one. can do. Of course, it is not necessary to always supply AC power to a control device (eg, home server, air conditioner, etc.) for time adjustment. Such wasteful power consumption can be suppressed.

図２は、本発明に係る時刻情報を送信する配電盤の別の実施の一形態を示すブロック図である。
配電盤１には、時刻情報送信手段２が必要である。しかし、配電盤１ないし時刻情報送信手段２が電力線３に送出する時刻情報の生成元、すなわち時計は、配電盤１の内部に設ける必要は必ずしもない。
時刻情報を生成する時計１２ａは、配電盤１の外部、例えば送電所１０に設けてもよい。この場合、送電所１０は、電力の送電だけでなく、時刻情報送信手段１２によって、時刻情報をも外線を介して、常時または定期的に、配電盤１へ送信する。配電盤１の時刻情報送信手段２は、受信する時刻情報を含む電力信号を電力線３へ送信する。その後の動作は、上述した図１の説明と同様なので詳細は省略する。図２では、電気機器Ａ６ａ及び電気機器Ｂ６ｂが電力の供給を受けるとともに、時刻情報をも受信する。
なお、図示しないけれども、本発明を実施するのに、送電所１０に時計１２ａを設け、配電盤１にも時計を設ける構成でもよい。この場合、普段は、配電盤１側の時計が出力する時刻情報を電力線３へ送出し、定期的に送電所１０からの時刻情報を配電盤１が受信して、配電盤１側の時計を合わせる、などすることができる。
なお、配電盤１に設ける時計または送電所１０に設ける時計は、標準電波時計であってもよいことはもちろんである。FIG. 2 is a block diagram showing another embodiment of a switchboard for transmitting time information according to the present invention.
The switchboard 1 requires time information transmission means 2. However, it is not always necessary to provide the time information generation source, that is, the clock, sent from the switchboard 1 to the time information transmission unit 2 to the power line 3.
The clock 12 a that generates time information may be provided outside the switchboard 1, for example, in the power transmission station 10. In this case, the power transmission station 10 transmits not only the power transmission but also the time information to the switchboard 1 constantly or periodically via the external line by the time information transmitting unit 12. The time information transmission means 2 of the switchboard 1 transmits a power signal including the received time information to the power line 3. Since the subsequent operation is the same as that of FIG. In FIG. 2, the electric device A6a and the electric device B6b are supplied with power and also receive time information.
In addition, although not shown in figure, in order to implement this invention, the structure which provides the timepiece 12a in the power transmission station 10, and provides the timepiece also in the switchboard 1 may be sufficient. In this case, usually, the time information output by the clock on the switchboard 1 side is sent to the power line 3, the time information from the power transmission station 10 is periodically received by the switchboard 1, and the clock on the switchboard 1 side is set. can do.
Of course, the timepiece provided on the switchboard 1 or the timepiece provided at the power transmission station 10 may be a standard radio timepiece.

図３は、配電盤に電力消費量変化検出手段を設けた本発明に係る時刻情報を送信する配電盤の実施の形態を示すブロック図である。
配電盤１に電力消費量変化検出手段９を設け、配電盤１から電力線３に流れ出る電力量（電流）を検出する。その変化が所定レベルを超えると、新たに電気機器Ｂ６ｂの電源プラグＢ５ｂがコンセントＢ４ｂに差し込まれたと、制御盤１が判断する。そこで、制御盤１は、時刻情報を電力線３に送信する。電気機器Ｂ６ｂは、他の電気機器（６ａ、６ｃ）同様、該時刻情報を受信する。もちろん、配電盤１は、定期的に時刻情報を電力線３に送信するとともに、それに加えて電力消費量変化検出手段９の検知レベルの所定量以上の変化の度に、時刻情報を収容している全ての電力線３に送信する構成でもよい。FIG. 3 is a block diagram showing an embodiment of a switchboard for transmitting time information according to the present invention in which power distribution amount change detection means is provided in the switchboard.
The switchboard 1 is provided with a power consumption change detecting means 9 to detect the amount of power (current) flowing out of the switchboard 1 to the power line 3. When the change exceeds a predetermined level, the control panel 1 determines that the power plug B5b of the electric device B6b is newly inserted into the outlet B4b. Therefore, the control panel 1 transmits time information to the power line 3. The electric device B6b receives the time information like the other electric devices (6a, 6c). Of course, the switchboard 1 periodically transmits time information to the power line 3, and in addition to this, every time the power level change detecting means 9 changes the detection level by a predetermined amount or more, all the time information is accommodated. A configuration of transmitting to the power line 3 may be used.

発明の効果The invention's effect

本発明に係る時刻情報を送信する配電盤は、以上説明してきたような構成であるので、以下に記載する効果を奏する。
配電盤は、外線と接続されており、停電にでもならない限り、その外線を介して常時電力の供給を受けている。従って、時刻情報の送信元装置である配電盤は、電源プラグをコンセントに差し込む必要がなく、時刻情報送信のために余計な電力を消費しない。また、配電盤に時計を設けた場合でも、その時計を駆動するための電力消費、及びその時計が生成する時刻情報を電力線へ送出するための電力消費は、微々たるものである。
時刻情報の供給を受ける家電製品は、未使用のときは、その電源プラグをコンセントから外しておき、使用するときになって、その電源プラグをコンセントに差し込めばよい。電力線から時刻情報を分離し得る手段を持つ家電製品であるなら、電力線からの受信時刻情報に基づき、自身の時計の時刻合わせが可能である。つまり、家電製品の節電と時刻合わせを両立させることができる。
また、従来のように、時刻合せシステムの時刻情報の送信元装置（例えばエアコン装置など）に常時通電しておく必要は全くない。
従って、電力線を利用する時刻合せシステムにおいて、時刻情報を送信する送信元、すなわち時刻合せシステムの制御部が電力をほとんど消費しない、時刻情報を送信する配電盤を提供することができる。Since the switchboard for transmitting time information according to the present invention is configured as described above, the effects described below are obtained.
The switchboard is connected to an external line, and is always supplied with power through the external line unless a power failure occurs. Therefore, the switchboard which is the time information transmission source device does not need to insert the power plug into the outlet, and does not consume extra power for transmitting the time information. Even when a clock is provided on the switchboard, power consumption for driving the clock and power consumption for sending time information generated by the clock to the power line are insignificant.
A household electrical appliance that is supplied with time information may be unplugged from the outlet when not in use, and then plugged into the outlet when it is in use. If the home appliance has a means capable of separating the time information from the power line, the time of its own clock can be set based on the reception time information from the power line. That is, it is possible to achieve both power saving and time adjustment of home appliances.
Further, unlike the prior art, there is no need to energize the time information transmission source device (for example, an air conditioner) at all times.
Therefore, in the time adjustment system using a power line, it is possible to provide a switchboard for transmitting time information in which a transmission source for transmitting time information, that is, a control unit of the time adjustment system consumes little power.
