【発明の属する技術分野】
本発明は、遠隔制御装置に関し、特に交流電源から負荷への電源供給線を利用して制御信号を送信する遠隔制御装置に関するものである。
【０００２】
【従来の技術】
従来から、負荷である例えば照明装置等に、電源を供給する電源供給線を利用して制御信号である例えば調光信号を伝送するようにした遠隔制御装置が知られている。
【０００３】
図７は、このような従来の遠隔制御装置（第１の従来例）の制御方式を示すもので、この制御方式は、交流電源ＡＣの電圧波形である正弦波のある２つの半波Ｍ１，Ｍ２を削除し、その削除された半波Ｍ１，Ｍ２間の所定時間Ｔ内の正弦波の周期数をカウントして、この周期数を調光信号としたものである。
【０００４】
図８は、従来の別の遠隔制御装置（第２の従来例）の制御方式を示すもので、前記第１の従来例と異なる点は、半波を削除するのに代えて所定位相各部分の波形Ｐ１，Ｐ２を削除するようにした点であり、他は前記第１の従来例と同様の方式としたものである。
【０００５】
【発明が解決しようとする課題】
しかしながら、このように構成された第１の従来例に示す遠隔制御装置の制御方式においては、負荷である照明装置に供給される電源波形に削除された半波Ｍ１，Ｍ２部分が存在するため、この部分で負荷に対する電源電圧の実効値が下がり、負荷に供給される電力が低下すると共に、負荷である照明装置にちらつきが発生してしまうという問題点があった。
【０００６】
また、第２の従来例に示す遠隔制御装置の制御方式においては、負荷に供給される電力低下は減少するものの、所定位相各部分の波形Ｐ１，Ｐ２が削除されているため電力低下は避けられず、また、照明装置のちらつきも少しはましにはなるものの、なおちらつきが発生するという問題点があった。
【０００７】
本発明は、上記問題点に鑑みてなされたもので、その目的とするところは、負荷に安定した電力を供給しながら負荷への電源供給線を利用して制御信号を送信できる遠隔制御装置を提供することにあり、また、別の目的とするところは、負荷が照明装置である場合に、そのちらつきをなくした遠隔制御装置を提供することにある。
【０００８】
【課題を解決するための手段】
本発明は上記の問題点を解決するため、請求項１記載の発明にあっては、交流電源ＡＣから電源供給線１を介して負荷２に印加される交流電圧の一部を適宜、前記負荷２の制御信号に加工して送信する制御親機３と、この制御親機３と前記電源供給線１を介して接続されると共に信号抽出部４ａで前記制御信号を抽出して負荷制御部４ｂに送信し前記負荷２を制御させる制御端末４とを備えた遠隔制御装置において、前記制御親機３が、前記交流電源ＡＣの電圧波形を振幅と周期が等しい異なる波形に加工する波形加工部３ａと、前記交流電圧波形の所定区間内の少なくとも一部の波形を、前記異なる波形に置き換えて前記負荷２に出力する波形演算部３ｂとを備えてなり、前記波形加工部３ａが、照明装置である負荷２に供給される電力が低下することがないように、商用電源である交流電源ＡＣの電圧波形を削除することなくその位相を反転させて異なる波形に加工するものであることを特徴とするものである。
【００１１】
請求項２記載の発明にあっては、請求項１記載の遠隔制御装置において、前記制御端末４の信号抽出部４ａが、前記電源供給線１を介して入力される電圧波形が、１周期毎に直前の波形に対して異なる波形である場合を１として制御信号を抽出することを特徴とするものである。
【００１２】
請求項３記載の発明にあっては、請求項１記載の遠隔制御装置において、前記制御端末４の信号抽出部４ａが、前記電源供給線１を介して入力される電圧波形が、１周期毎に前記交流電源ＡＣの電圧波形と異なる波形である場合を１として制御信号を抽出することを特徴とするものである。
【００１３】
請求項４記載の発明にあっては、請求項２、または請求項３記載の遠隔制御装置において、前記制御端末４が、連続した１の数をカウントして前記負荷２を制御したことを特徴とするものである。
【００１４】
請求項５記載の発明にあっては、請求項２、または請求項３記載の遠隔制御装置において、前記負荷制御部４ｂで前記信号抽出部４ａから送信される制御信号をデジタル信号として前記負荷２を制御させたことを特徴とするものである。
【００１６】
【発明の実施の形態】
図１及び図２は、本発明の遠隔制御装置の第１の実施の形態を示すものであり、この遠隔制御装置は、制御親機３と制御端末４とを備えて構成されている。
【００１７】
制御親機３は、交流電源ＡＣである商用電源に接続されてなり、その交流電圧波形Ａを異なる波形である振幅と周期が同じで位相を反転させた波形Ｂに加工する波形加工部３ａと、この波形加工部３ａの出力波形である異なる波形Ｂと交流電源ＡＣの電圧波形Ａとを組み合わせて、つまり、所定区間Ｔ内の交流電源ＡＣの電圧波形Ａを異なる波形Ｂと置き換えて出力する波形演算部３ｂと、波形演算部３ｂを制御する制御部３ｃと、その制御部３ｃへ制御状態を入力・指令する入力部３ｄ、及び波形加工部３ａや波形演算部３ｂ及び制御部３ｃ等に動作電源を供給する電源部３ｅとを備えて構成されている。また、波形演算部３ａの出力側が負荷２である例えば照明装置の電源供給線１に接続されており、制御信号を送信しないときには、交流電源ＡＣの交流電圧波形である波形Ａがそのまま出力されるようにされている。
【００１８】
したがって、この電源供給線１には、制御信号が送信されていないときには商用電源ＡＣの交流電圧波形Ａである正弦波が印加されており、制御信号を送信するときには、制御部３ｃにより波形演算部３ｂが制御されて、波形演算部３ｂで交流電圧波形Ａの途中で波形が異なる波形Ｂと入れ替えられ、制御信号の送信が完了すると再び波形が元の交流電圧波形Ａに戻るようにされている。そして、例えば数値１０を制御信号として送信させる場合には、交流電圧波形Ａの途中の例えばゼロクロスする点で波形が異なる波形Ｂと入れ替えられて位相が反転するように変化し、波形Ｂが１０周期送られた後にゼロクロスする点で、位相が反転して波形が元の交流電圧波形Ａに戻るようにされている。つまり、電源供給線１に印加される負荷２への電源波形Ｃは、位相の反転する２点間の所定区間Ｔ内に、１０周期分の異なる波形Ｂが出力されるようにされており、２つの位相の変化点では、同じ極性の半波が連続するようにされているのである。
【００１９】
制御端末４は、波形演算部３ｂの出力側から延出された電源供給線１に接続されてなり、その電源供給線１から制御信号を抽出する信号抽出部４ａと、信号抽出部４ａからの制御信号により負荷２である照明装置を制御させる負荷制御部４ｂと、信号抽出部４ａと負荷制御部４ｂの電源部４ｃとを備えて構成されている。そして、信号抽出部４ａで波形演算部３ｂから出力される負荷２への電源波形Ｃから、位相の反転する２点間の所定区間Ｔ内に送信される異なる波形Ｂの周期数を抽出するようにされている。
【００２０】
このように構成されているため、本実施の形態における遠隔制御装置においては、負荷２に電源を供給する電源供給線１を利用して制御信号の送信ができて、信号線を設ける必要がなく、また、負荷２への電源波形Ｃに波形の削除された部分がないため、負荷２に安定した電力を供給することができると共に、負荷２が照明装置であってもちらつきが生ずることがない。
【００２１】
図３は、本発明の遠隔制御装置の第１の参考例を示すものであり、前記第１の実施の形態と異なる点は、波形加工部３ａから出力される異なる波形Ｂを、交流電源ＡＣの電圧波形Ａを全波整流した波形とした点であり、他は前記第１の実施の形態と同様に構成されている。
【００２２】
図４は、本発明の遠隔制御装置の第２の実施の形態を示すものであり、前記第１の実施の形態と異なる点は、制御親機３が、波形演算部３ａから出力されて電源供給線１に印加される負荷２への電源波形Ｃが、１周期毎に直前の波形に対して異なる波形Ｂである場合、つまり、ここでは位相が異なる場合を１とし、そうでない場合を０とした制御信号を送信すると共に、制御端末４の信号抽出部４ａでその電圧波形からデジタル信号として制御信号を抽出させて負荷制御部４ｂに送信させることにより負荷２を制御させて、信号抽出部４ａで連続した１の数をカウントさせて負荷２を制御した点であり、他は前記第１の実施の形態と同様に構成されている。このように構成しても、前記第１の実施の形態と同様の効果を奏する。
【００２３】
図５及び図６は、本発明の遠隔制御装置の第２の参考例を示すものであり、前記第１の参考例と異なる点は、制御端末４にアドレス設定部４ｄを設けた点と、制御親機３が、波形演算部３ａから出力されて電源供給線１に印加される負荷２への電源波形Ｃを１周期毎に交流電源ＡＣの電圧波形Ａと異なる波形である場合、つまり、ここでは全波整流された波形である場合を１として、交流電源ＡＣの電圧波形Ａである場合を０として、例えば調歩同期通信方式のようなフォーマットにしたがって負荷２のアドレスと共に制御信号を送信させた点と、制御端末４の信号抽出部４ａでその電圧波形からアドレス信号とデジタル信号としての制御信号を抽出させて負荷制御部４ｂに送信させた点であり、他は前記第１の参考例と同様に構成されている。
【００２４】
なお、前記各実施の形態においては、異なる波形Ｂの位相が異なる波形を、交流電源ＡＣの電圧波形の位相を反転させた、つまり１８０度ずらせた波形としたものである。
【００２５】
【発明の効果】
このように構成されているため本発明にあっては、負荷に電源を供給する電源供給線を利用して制御信号の送信ができて、信号線を設ける必要がなく、また、負荷の電源波形に波形の削除された部分がないため、負荷に安定した電力を供給することができて、負荷である照明装置にちらつきがなくなる。

[0016]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 and FIG. 2 show a first embodiment of a remote control device of the present invention, and this remote control device comprises a control master unit 3 and a control terminal 4.
[0017]
The control master unit 3 is connected to a commercial power source that is an AC power source AC, and has a waveform processing unit 3a that processes the AC voltage waveform A into a waveform B that has the same amplitude and cycle and is inverted in phase. The different waveform B, which is the output waveform of the waveform processing unit 3a, is combined with the voltage waveform A of the AC power source AC, that is, the voltage waveform A of the AC power source AC in the predetermined section T is replaced with a different waveform B and output. The waveform calculation unit 3b, the control unit 3c that controls the waveform calculation unit 3b, the input unit 3d that inputs and commands the control state to the control unit 3c, the waveform processing unit 3a, the waveform calculation unit 3b, the control unit 3c, etc. And a power supply unit 3e for supplying operating power. Further, when the output side of the waveform calculation unit 3a is connected to the power supply line 1 of the lighting device, for example, the load 2, and the control signal is not transmitted, the waveform A that is the AC voltage waveform of the AC power supply AC is output as it is. Has been.
[0018]
Therefore, a sine wave that is the AC voltage waveform A of the commercial power supply AC is applied to the power supply line 1 when no control signal is transmitted. When the control signal is transmitted, the control unit 3c performs a waveform calculation unit. 3b is controlled, and the waveform calculation unit 3b replaces the waveform B with a different waveform in the middle of the AC voltage waveform A. When the transmission of the control signal is completed, the waveform returns to the original AC voltage waveform A again. . For example, when the numerical value 10 is transmitted as a control signal, the waveform B is changed so that the phase is inverted by replacing the waveform B with a different waveform at the point where, for example, zero crossing occurs in the middle of the AC voltage waveform A, and the waveform B has 10 cycles. At the point of zero crossing after being sent, the phase is inverted and the waveform returns to the original AC voltage waveform A. That is, the power waveform C to the load 2 applied to the power supply line 1 is set so that a different waveform B for 10 cycles is output within a predetermined section T between two points whose phases are inverted. At the two phase change points, half waves of the same polarity are made continuous.
[0019]
The control terminal 4 is connected to a power supply line 1 extended from the output side of the waveform calculation unit 3b, and extracts a control signal from the power supply line 1, and a signal extraction unit 4a from the signal extraction unit 4a. A load control unit 4b that controls the lighting device that is the load 2 by a control signal, a signal extraction unit 4a, and a power supply unit 4c of the load control unit 4b are configured. Then, the signal extraction unit 4a extracts the number of periods of different waveforms B transmitted within a predetermined section T between two points whose phases are inverted from the power supply waveform C to the load 2 output from the waveform calculation unit 3b. Has been.
[0020]
Since it is configured in this manner, in the remote control device according to the present embodiment, it is possible to transmit a control signal using the power supply line 1 that supplies power to the load 2, and there is no need to provide a signal line. In addition, since there is no waveform deleted portion in the power supply waveform C to the load 2, stable power can be supplied to the load 2 and flickering does not occur even if the load 2 is a lighting device. .
[0021]
FIG. 3 shows a first reference example of the remote control device of the present invention, which is different from the first embodiment in that a different waveform B output from the waveform processing unit 3a is converted into an AC power supply AC. The voltage waveform A is a waveform obtained by full-wave rectification, and the rest is configured in the same manner as in the first embodiment .
[0022]
Figure 4 shows a second embodiment of the remote control device of the present invention, the is different from the first embodiment, the control base unit 3, is outputted from the waveform calculation unit 3a Power When the power supply waveform C to the load 2 applied to the supply line 1 is a waveform B different from the previous waveform every cycle, that is, here, the case where the phase is different is 1, and the case where it is not is 0 The signal extraction unit 4a of the control terminal 4 extracts the control signal as a digital signal from the voltage waveform and transmits the control signal to the load control unit 4b to control the load 2, and the signal extraction unit The load 2 is controlled by counting the number of consecutive 1's in 4a, and the rest is configured in the same manner as in the first embodiment. Even if comprised in this way, there exists an effect similar to the said 1st Embodiment.
[0023]
5 and 6 show a second reference example of the remote control device of the present invention. The difference from the first reference example is that an address setting unit 4d is provided in the control terminal 4, and When the control master 3 has a waveform different from the voltage waveform A of the AC power supply AC every cycle, the power waveform C to the load 2 output from the waveform calculation unit 3a and applied to the power supply line 1 is Here, a case where the waveform is a full-wave rectified waveform is set to 1, and a case where the waveform is the voltage waveform A of the AC power supply AC is set to 0. For example, the control signal is transmitted together with the address of the load 2 according to a format such as an asynchronous communication system. And the point that the signal extraction unit 4a of the control terminal 4 extracts the address signal and the control signal as a digital signal from the voltage waveform and transmits them to the load control unit 4b, and the others are the first reference example. Configured in the same way .
[0024]
Incidentally, in the above each embodiment, the phase of the different waveform B is different waveforms obtained by inverting the phase of the AC power supply AC voltage waveform, that is obtained by a 180 ° shifted allowed waveform.
[0025]
