Description

【０００１】
【発明の属する技術分野】
本発明は、信号線を介して親機と接続され、親機から信号線を介して伝送される指令に応じて１乃至複数の照明負荷の点滅制御並びに調光制御を行う調光制御装置を備えた調光制御システムに関するものである。
【０００２】
【従来の技術】
従来の調光制御装置（調光制御端末器）Ｂ及び調光制御システムの一例を図４に示す。この従来システムは、商用電源（図示せず）から複数の照明負荷（照明器具）Ｌ１〜Ｌ４への電力供給をオン／オフして点滅（点灯又は消灯）制御するためのオン／オフ制御端末器Ａ、各照明器具Ｌ１〜Ｌ４の光出力を変化させるための調光信号を出力する調光制御端末器（調光制御装置）Ｂ、照明器具Ｌ１〜Ｌ４を点灯／消灯するための点滅スイッチの操作状態を監視し、点滅スイッチが操作されたときに監視信号を出力する監視端末器（図示せず）、照明器具Ｌ１〜Ｌ４の調光率（全点灯時の光出力を１００％としたときの比率）を設定する操作スイッチの操作状態を監視し、操作スイッチが操作されたときに監視信号を出力する監視端末器（図示せず）等が信号線Ｌｓを介して親機Ｍに接続されて構成される。
【０００３】
親機Ｍは各端末器に割り当てられた固有のアドレスで個々の端末器を識別するとともに、監視端末器とオン／オフ制御端末器Ａ及び調光制御端末器Ｂとのアドレスの対応関係を予め記憶しており、信号線Ｌｓを介して監視信号を受信すると、監視信号を送信した監視端末器とアドレスの対応関係が設定されている制御端末器（オン／オフ制御端末器Ａ又は調光制御端末器Ｂ）に対して監視信号に応じた指令、例えば制御対象の照明器具Ｌ１，…を点灯する点灯指令又は消灯する消灯指令、あるいは照明器具Ｌ１の調光率を指令する調光率指令と、制御対象の照明器具Ｌ１，…を指定するアドレス（負荷アドレス）とを信号線Ｌｓを介してオン／オフ制御端末器Ａ並びに調光制御端末器Ｂに出力する。
【０００４】
一方、オン／オフ制御端末器Ａは、各照明器具Ｌ１〜Ｌ４とそれぞれ給電線Ｔ１〜Ｔ４を介して接続され、商用電源から給電線Ｔ１〜Ｔ４を介して各照明器具Ｌ１〜Ｌ４に給電する給電経路をそれぞれ開閉する複数のリレーを具備しており、信号線Ｌｓを介して親機Ｍから受信した点灯指令又は消灯指令に応じてリレーを駆動し、負荷アドレスで指定される照明器具Ｌ１，…への給電経路を開閉することによって制御対象の照明器具Ｌ１，…を点灯又は消灯する。
【０００５】
また、調光制御端末器Ｂは、一対の電線からなる調光信号線Ｋにて各照明器具Ｌ１〜Ｌ４が送り配線されており、親機Ｍから受信した調光率指令に応じた調光信号（照明器具Ｌ１，…の光出力を調光率に応じたレベルに変化させるための信号）を調光信号線Ｋを介して各照明器具Ｌ１〜Ｌ４に出力する。
【０００６】
照明器具Ｌ１〜Ｌ４は、例えば蛍光灯などの光源と、商用電源から供給される交流電力を電力変換して光源に供給する調光器等を具備し、調光信号線Ｋを介して受け取った調光信号に応じて調光器から光源への出力を可変することで光源の光出力を指定された調光率に一致させる。
【０００７】
上述のように構成された従来例の動作を簡単にまとめる。例えば照明器具Ｌ１が消灯している状態で照明器具Ｌ１とアドレスの対応関係が設定された監視端末器の点滅スイッチが押操作されると、この監視端末器から信号線Ｌｓを介して監視信号が親機Ｍに送信される。上記監視信号を受信した親機Ｍは、監視信号の送信元である監視端末器を監視信号に含まれるアドレスから認識し、このアドレスと対応関係が設定されたオン／オフ制御端末器Ａのアドレスに対して点灯指令を送信する。なお、上記アドレスはオン／オフ制御端末器Ａを特定するアドレスに制御対象とする複数の照明器具Ｌ１〜Ｌ４を指定する負荷アドレスを組み合わせたものである。そして、信号線Ｌｓを介して親機Ｍからの点灯指令を受信したオン／オフ制御端末器Ａでは、上述のようにリレーを駆動して負荷アドレスで指定される照明器具Ｌ１への給電経路を閉成することによって商用電源から電源供給を行って制御対象の照明器具Ｌ１を点灯させる。
【０００８】
一方、照明器具Ｌ１が点灯している状態で照明器具Ｌ１とアドレスの対応関係が設定された監視端末器の操作スイッチが操作されると、この監視端末器から信号線Ｌｓを介して監視信号が親機Ｍに送信される。この監視信号を受信した親機Ｍは、監視信号の送信元である監視端末器を監視信号に含まれるアドレスから認識し、このアドレスと対応関係が設定された調光制御端末器Ｂのアドレスに対して操作スイッチの操作に応じた調光率を指令する調光率指令を送信する。そして、信号線Ｌｓを介して親機Ｍからの点灯指令を受信した調光制御端末器Ｂでは、上述のように親機Ｍから受信した調光率指令に応じた調光信号を調光信号線Ｋに出力することにより、点灯状態にある照明器具Ｌ１の調光率を指定された調光率に一致させる。
【０００９】
【発明が解決しようとする課題】
しかしながら、上記従来システムにおいては、照明器具Ｌ１，…の点滅制御と調光制御をオン／オフ制御端末器Ａと調光制御端末器Ｂの２種類の端末器で別々に行っているため、親機Ｍとの接続のための信号線Ｌｓの配線作業が繁雑になり、施工に多大な手間がかかるという問題がある。一方、調光率が０％に指定されると商用電源から調光器への給電を停止して消灯するタイプの照明器具（以下、このタイプの照明器具を「調光切り型照明器具」と呼ぶ）が最近になって提供され始めているが、上記従来システムや調光制御端末器Ｂでは、このような調光切り型照明器具に対応することはできなかった。
【００１０】
本発明は上記問題に鑑みて為されたものであり、その目的は、いわゆる調光切り型照明器具からなる照明負荷が使用可能となって信号線の配線作業が簡素化できる調光制御システムを提供することにある。
【００１１】
【課題を解決するための手段】
請求項１の発明は、上記目的を達成するために、１乃至複数の調光制御装置と、各調光制御装置と信号線を介して接続され、各調光制御装置に対して照明負荷の点灯、消灯又は調光率を指令する親機と、各調光制御装置から出力される制御指令に応じて点灯、消灯又は調光される１乃至複数の照明負荷とを備え、調光制御装置は、信号線を介して照明負荷の点灯を指示する点灯指令又は消灯を指示する消灯指令を受信する第１の受信手段と、信号線を介して照明負荷の全点灯に対する光出力の割合を０％〜１００％の比率で表した調光率を指令する調光率指令を受信する第２の受信手段と、第１の受信手段で受信した点灯指令又は消灯指令と第２の受信手段で受信した調光率指令を演算処理して照明負荷を制御するための制御指令を作成する制御処理手段と、制御処理手段から与えられる制御指令に応じて各照明負荷の光出力を設定するための調光信号を出力する調光信号出力手段とを備え、制御処理手段は、点灯指令、消灯指令及び調光率指令を記憶するとともに、点灯指令受信時には、記憶している調光率指令に従って照明負荷を調光制御するための制御指令を作成し、調光率指令受信時には照明負荷を指令された調光率で調光制御するための制御指令を作成し、消灯指令受信時には照明負荷を消灯させるための制御指令を作成し、０％の調光率を指令する調光率指令受信時には照明負荷を０％の調光率で調光制御するための制御指令を作成し、各照明負荷は、０％の調光率で調光するための制御指令を受け取ると消灯することを特徴とし、いわゆる調光切り型照明器具からなる照明負荷の点滅制御並びに調光制御が調光率の指定によって行え、従来のオン／オフ制御端末器が不要となって信号線の配線作業が簡素化できる。
【００１３】
【発明の実施の形態】
図１〜図３を参照して本発明の実施形態を詳細に説明する。
【００１４】
図１は本実施形態の調光制御装置Ｄを示すブロック図である。この調光制御装置Ｄは、親機Ｍとの間で信号線Ｌｓを介して伝送信号を送受信し、調光切り型照明器具（以下、特に断らない限りは「照明器具」と略す）Ｌ１’，…の点灯を指示する点灯指令又は消灯を指示する消灯指令を受信する第１の送受信部１と、同じく親機Ｍとの間で信号線Ｌｓを介して伝送信号を送受信し、照明器具Ｌ１’，…の調光率を指令する調光率指令を受信する第２の送受信部２と、第１の送受信部１で受信した点灯指令又は消灯指令と第２の送受信部２で受信した調光率指令を演算処理して照明器具Ｌ１’，…を制御するための制御指令を作成する制御処理部３と、制御処理部３から与えられる制御指令に応じて各照明器具Ｌ１’，…の光出力を設定するための調光信号を出力する調光信号出力部４とを備える。
【００１５】
第１及び第２の送受信部１，２は、親機Ｍから信号線Ｌｓを介して送信される、図３に示すフォーマットの伝送信号Ｕによって、点灯指令、消灯指令並びに調光率指令を受信する。この伝送信号Ｕは、信号送出開始を示す同期信号ＳＹ、伝送信号Ｕのモードを示すモードデータＭＤ、調光制御装置Ｄを含む端末器を各別に呼び出すためのアドレスデータＡＤ、照明器具Ｌ１’，…を制御する制御データＣＤ、伝送誤りを検出するためのチェックサムデータＣＳ、監視端末器Ｅ等からの返送信号（監視データ）を受信するタイムスロットである信号返送期間ＷＴよりなる双極性の時分割多重信号であり、パルス幅変調によってデータが伝送されるようになっている。そして、第１及び第２の送受信部１，２では、信号線Ｌｓを介して受信した伝送信号Ｕにより伝送されたアドレスデータＡＤがあらかじめ設定されているアドレスに一致すると、伝送信号Ｕから制御データＣＤを取り込み、取り込んだ制御データを制御処理部３に出力する。すなわち、点灯指令、消灯指令並びに調光率指令は制御データＣＤとして送信される。なお、第１及び第２の送受信部１，２は、上述のように同じフォーマットの伝送信号Ｕを受信するものであるから、別々の回路で構成せずとも１つの回路で構成可能である。
【００１６】
制御処理部３は、第１及び第２の送受信部１，２から入力された制御データのうちで点灯指令又は消灯指令を記憶する第１の記憶部３ａと、調光率指令を記憶する第２の記憶部３ｂと、マイクロコンピュータで構成された演算処理部３ｃとを具備する。この演算処理部３ｃは、第１の記憶部３ａに記憶された点灯指令又は消灯指令と、第２の記憶部３ｂに記憶された調光率指令とを論理演算して制御指令を作成し、作成した制御指令を調光信号出力部４に出力する。
【００１７】
調光信号出力部４は、演算処理部３ｃから受け取った制御指令に応じて照明器具Ｌ１’，…を点灯、消灯又は調光制御するための調光信号を調光信号線Ｋに出力する。そして、調光信号線Ｋを介して調光信号を受信した照明器具Ｌ１’，…では調光信号に応じて調光器の出力調整を行うのである。
【００１８】
次に、演算処理部３ｃにおける論理演算の具体的な内容について説明する。
【００１９】
まず、第１の送受信部１で点灯指令を受信した場合、第１の記憶部１の記憶内容を点灯指令に書き換えるとともに、第２の記憶部３ｂに記憶している調光率にて照明器具Ｌ１’，…を調光点灯（但し、調光率が１００％の時は全点灯）させるための調光信号（電圧信号）を調光信号線Ｋに出力する。また、第２の送受信部２で０％以外の調光率指令を受信した場合、第２の記憶部３ｂに記憶している調光率を書き換えるとともに、照明器具Ｌ１’，…が点灯中（第１の記憶部３ａに点灯指令が記憶されている状態）であれば、書き換えられた調光率にて照明器具Ｌ１’，…を調光点灯させるための調光信号を調光信号線Ｋに出力する。さらに、第１の送受信部１で消灯指令を受信した場合、第１の記憶部３ａの記憶内容を消灯指令に書き換えるとともに、照明器具Ｌ１’，…を消灯させるための調光信号、すなわち、調光率０％に対応した調光信号を調光信号線Ｋに出力する。最後に、第２の送受信部２で０％の調光率指令を受信した場合、第１の記憶部３ａの記憶内容を消灯指令に書き換えるとともに第２の記憶部３ｂに記憶している調光率を０％に書き換え、調光率０％に対応した調光信号を調光信号線Ｋに出力する。
【００２０】
図２は本実施形態の調光制御装置Ｄを端末器として備える調光制御システムのシステム構成図を示している。すなわち、本実施形態の調光制御装置Ｄと、従来例で説明したように照明器具Ｌ１’，…を点灯／消灯するための点滅スイッチの操作状態を監視し、点滅スイッチが操作されたときに監視信号（監視データ）を出力する監視端末器Ｅと、照明器具Ｌ１’，…の調光率を設定する操作スイッチの操作状態を監視し、操作スイッチが操作されたときに監視信号を出力する監視端末器（図示せず）等が信号線Ｌｓを介して親機Ｍに接続されて構成される。但し、図示は省略しているが、各照明器具Ｌ１'，…には商用電源から給電線を介して給電される。
【００２１】
例えば、消灯中の照明器具Ｌ１’，…を点灯するために監視端末器Ｅで点滅スイッチが操作されると、親機Ｍから調光制御装置Ｄに対して点灯指令を制御データとする伝送信号Ｕが送信される。また、照明器具Ｌ１’，…の調光率を７０％に設定するために監視端末器で操作スイッチが操作されると、親機Ｍから調光制御装置Ｄに対して調光率７０％の調光率指令を制御データとする伝送信号Ｕが送信される。調光制御装置Ｄでは、上述のように第１の送受信部１で点灯指令を受信して第１の記憶部３ａに記憶するとともに第２の送受信部２で調光指令を受信して第２の記憶部３ｂに記憶し、演算処理部３ｃにて照明器具Ｌ１’，…を調光率７０％で調光点灯させるための制御指令を作成して調光信号出力部４に出力し、調光信号出力部４から照明器具Ｌ１’，…を調光率７０％で調光点灯するための調光信号を調光信号線Ｋに出力する。そして、調光信号線Ｋを介して調光信号を受信した照明器具Ｌ１’，…では、調光器の出力が調整されて調光率７０％で調光点灯する。
【００２２】
一方、点灯中の照明器具Ｌ１’，…を消灯するために監視端末器Ｅで点滅スイッチが操作されると、親機Ｍから調光制御装置Ｄに対して消灯指令を制御データとする伝送信号Ｕが送信される。調光制御装置Ｄでは、上述のように第１の送受信部１で消灯指令を受け取ると第１の記憶部３ａの内容を消灯指令に書き換え、演算処理部３ｃにて照明器具Ｌ１’，…を調光率を０％とする制御指令を作成して調光信号出力部４に出力し、調光信号出力部４から照明器具Ｌ１’，…を調光率を０％とする調光信号を調光信号線Ｋに出力する。そして、調光信号線Ｋを介して調光率０％の調光信号を受信した照明器具Ｌ１’，…では、調光器が出力を停止して消灯する。
【００２３】
本実施形態は上述のように構成され、いわゆる調光切り型照明器具の点滅制御並びに調光制御が調光率の指定によって行え、従来のオン／オフ制御端末器Ａが不要となって信号線Ｌｓの配線作業が簡素化できるという利点がある。しかも、本実施形態の調光制御装置Ｄは、従来例の調光制御端末器Ｂと同じハードウェア構成を用い、演算処理部３ｃのソフトウェアを変更して上述の演算処理を実行させるだけで済むために大幅なコストダウンが図れる。

BACKGROUND OF THE INVENTION
The present invention provides a dimming control device that is connected to a master unit via a signal line and performs blinking control and dimming control of one or more lighting loads in response to a command transmitted from the master unit via the signal line. The present invention relates to a dimming control system provided .
[0002]
[Prior art]
An example of a conventional light control device (light control terminal) B and a light control system is shown in FIG. This conventional system is an on / off control terminal for turning on / off power supply from a commercial power supply (not shown) to a plurality of lighting loads (lighting fixtures) L1 to L4 to control blinking (lighting or extinguishing). A, a dimming control terminal (a dimming control device) B that outputs a dimming signal for changing the light output of each of the lighting fixtures L1 to L4, and a flashing switch for turning on / off the lighting fixtures L1 to L4 A monitoring terminal (not shown) that monitors the operating state and outputs a monitoring signal when the blinking switch is operated, the dimming rate of the lighting fixtures L1 to L4 (when the light output when fully lit is 100%) The monitoring terminal (not shown) that monitors the operation state of the operation switch that sets the ratio) and outputs a monitoring signal when the operation switch is operated is connected to the main unit M via the signal line Ls. Configured.
[0003]
The master unit M identifies each terminal unit with a unique address assigned to each terminal unit, and predetermines the correspondence between addresses of the monitoring terminal unit and the on / off control terminal unit A and dimming control terminal unit B. When the monitoring signal is stored and received via the signal line Ls, the control terminal (on / off control terminal A or dimming control) in which the correspondence relationship between the monitoring terminal that transmitted the monitoring signal and the address is set. A command corresponding to the monitoring signal to the terminal device B), for example, a lighting command to turn on or turn off the lighting fixtures L1,..., Or a dimming rate command to command the dimming rate of the lighting fixture L1; The addresses (load addresses) for designating the lighting fixtures L1,... To be controlled are output to the on / off control terminal A and the dimming control terminal B via the signal line Ls.
[0004]
On the other hand, the on / off control terminal A is connected to each of the lighting fixtures L1 to L4 via the feed lines T1 to T4, respectively, and supplies power to each of the lighting fixtures L1 to L4 from the commercial power source via the feed lines T1 to T4. A plurality of relays each for opening and closing the power supply path are provided, the relays are driven in accordance with the lighting command or the lighting-off command received from the master unit M via the signal line Ls, and the lighting fixtures L1, L1 specified by the load address are provided. The lighting fixtures L1,... To be controlled are turned on or off by opening and closing the power supply path to.
[0005]
In the dimming control terminal B, the lighting fixtures L1 to L4 are sent and wired by the dimming signal line K composed of a pair of electric wires, and dimming according to the dimming rate command received from the master unit M is performed. A signal (a signal for changing the light output of the lighting fixtures L1,... To a level corresponding to the dimming rate) is output to each of the lighting fixtures L1 to L4 via the dimming signal line K.
[0006]
The luminaires L1 to L4 include, for example, a light source such as a fluorescent lamp and a dimmer that converts AC power supplied from a commercial power source and supplies the converted light to the light source. By varying the output from the dimmer to the light source in accordance with the dimming signal, the light output of the light source is matched with the designated dimming rate.
[0007]
The operation of the conventional example configured as described above will be briefly summarized. For example, when the blinking switch of the monitoring terminal in which the correspondence relationship between the lighting apparatus L1 and the address is set is pressed while the lighting apparatus L1 is turned off, the monitoring signal is transmitted from the monitoring terminal via the signal line Ls. It is transmitted to the base unit M. The master unit M that has received the monitoring signal recognizes the monitoring terminal that is the transmission source of the monitoring signal from the address included in the monitoring signal, and the address of the on / off control terminal A that has a corresponding relationship with this address. A lighting command is transmitted to. In addition, the said address combines the load address which designates several lighting fixtures L1-L4 made into a control object in the address which specifies ON / OFF control terminal A. Then, in the on / off control terminal A that has received the lighting command from the master unit M via the signal line Ls, the power supply path to the lighting fixture L1 specified by the load address by driving the relay as described above is provided. By closing, power is supplied from a commercial power source to turn on the lighting fixture L1 to be controlled.
[0008]
On the other hand, when the operation switch of the monitoring terminal device in which the correspondence relationship between the lighting device L1 and the address is set is operated in a state where the lighting device L1 is lit, a monitoring signal is transmitted from the monitoring terminal device via the signal line Ls. It is transmitted to the base unit M. The master unit M that has received this monitoring signal recognizes the monitoring terminal that is the transmission source of the monitoring signal from the address included in the monitoring signal, and sets the address of the dimming control terminal B that has a corresponding relationship with this address. A dimming rate command for commanding a dimming rate according to the operation of the operation switch is transmitted. Then, in the dimming control terminal B that has received the lighting command from the master unit M via the signal line Ls, the dimming signal corresponding to the dimming rate command received from the master unit M as described above is used as the dimming signal. By outputting to the line K, the dimming rate of the lighting fixture L1 in the lighting state is made to coincide with the designated dimming rate.
[0009]
[Problems to be solved by the invention]
However, in the above-described conventional system, the blinking control and the dimming control of the lighting fixtures L1,... Are performed separately by the two types of terminals, the on / off control terminal A and the dimming control terminal B. The wiring work of the signal line Ls for connection with the machine M becomes complicated, and there is a problem that a lot of work is required for the construction. On the other hand, when the dimming rate is specified as 0%, a lighting fixture of a type that stops power supply from the commercial power supply to the dimmer and extinguishes (hereinafter, this type of lighting fixture is referred to as a “dimming lighting fixture”). However, the conventional system and the dimming control terminal B cannot cope with such a dimming type lighting fixture.
