Description

本発明は、赤外線や特定小電力無線通信方式を用いた照明装置の無線式調光制御システムに関する。   The present invention relates to a wireless dimming control system for a lighting device using infrared rays or a specific low power wireless communication system.

従来から、遠隔操作装置を操作して照明装置の明るさを制御する無線式調光制御システムが実用化されている（特許文献１参照）。従来の無線式調光制御システムについて、図４を参照しつつ説明する。照明装置の調光レベルは、レベル１からレベル６までの６段階に調光可能であるとする。調光レベルがレベル１に設定されており、調光レベルを高くしようとする場合、ユーザは、遠隔操作装置に設けられている調光アップボタン（例えば、△ボタン）を操作する。遠隔操作装置は、ユーザが調光アップボタンを連続して押し続けている間、一定の間隔で所定の調光信号（調光アップ信号）を出力する。あるいは、ユーザが調光アップボタンを押している時間が所定の時間よりも短い場合は、ユーザが一度調光アップボタンを操作するたびに、１つずつ所定の調光信号を出力する。   Conventionally, a wireless dimming control system that operates a remote control device to control the brightness of a lighting device has been put into practical use (see Patent Document 1). A conventional wireless dimming control system will be described with reference to FIG. It is assumed that dimming levels of the lighting device can be dimmed in six levels from level 1 to level 6. When the dimming level is set to level 1 and the user wants to increase the dimming level, the user operates a dimming up button (for example, a Δ button) provided in the remote control device. The remote control device outputs a predetermined dimming signal (dimming up signal) at regular intervals while the user continues to press the dimming up button. Alternatively, when the time during which the user presses the dimming up button is shorter than the predetermined time, a predetermined dimming signal is output one by one each time the user operates the dimming up button.

照明装置では、受信部が遠隔操作装置からの調光アップ信号を受信するたびに、制御部は調光レベルを１段階ずつ高くする。ユーザは、自分の好みの調光レベル（明るさ）に到達した時点で、調光アップボタンの操作を停止する。照明装置の制御部は、遠隔操作装置からの新たな調光信号を受信するまで、そのときの調光レベルを記憶し、維持する。調光レベルを低くしようとする場合は、遠隔操作装置に設けられている調光ダウンボタン（例えば、▽ボタン）を操作すればよく、遠隔操作装置及び照明装置における動作は同様である。   In the illumination device, the control unit increases the dimming level by one step each time the receiving unit receives the dimming up signal from the remote control device. The user stops the operation of the dimming up button when the user's favorite dimming level (brightness) is reached. The control unit of the lighting device stores and maintains the light control level at that time until a new light control signal is received from the remote control device. In order to lower the dimming level, a dimming down button (for example, the ▽ button) provided in the remote operation device may be operated, and the operations in the remote operation device and the lighting device are the same.

従来の無線式調光制御システムでは、遠隔操作装置のＬＥＤ発光部と照明装置の受信部との間に障害物が存在すると、調光信号が正しく送受信されないという問題点を有していた。そのため、近年、特定小電力無線通信方式の規格（ＳＴＤ−Ｔ６７など）を用いた電波による無線式調光制御システムも提案されている。ところが、例えばＳＴＤ−Ｔ６７によれば、信号送信時間は５秒以内であり、その後必ず２秒間信号送信してはならないという規定が存在するため、調光動作を５秒以内に終了させる必要がある。ところが、ユーザによって、遠隔操作装置の調光アップボタン又は調光ダウンボタンの操作は様々であり、調光動作を５秒以内に終了させられない場合も起こり得る。特に、ユーザによる調光アップボタン又は調光ダウンボタンの操作が長い場合、最初の調光信号の送信開始から５秒を経過した時点で強制的に調光信号の送信が停止されてしまい、その後一定時間調光信号が送信できないため、調光信号が失報し、ユーザは遠隔操作装置又は照明制御装置の故障であると勘違いする可能性があるという問題点を有していた。
特開平５−７６０６４号公報 The conventional wireless dimming control system has a problem in that the dimming signal is not correctly transmitted and received when an obstacle exists between the LED light emitting unit of the remote control device and the receiving unit of the lighting device. Therefore, in recent years, a wireless dimming control system using radio waves using a standard (STD-T67 or the like) of a specific low power wireless communication system has been proposed. However, according to STD-T67, for example, there is a regulation that the signal transmission time is within 5 seconds, and then signal transmission must not be performed for 2 seconds, so the dimming operation needs to be completed within 5 seconds. . However, the operation of the dimming up button or dimming down button of the remote control device varies depending on the user, and the dimming operation may not be completed within 5 seconds. In particular, when the user operates the dimming up button or the dimming down button for a long time, the transmission of the dimming signal is forcibly stopped when 5 seconds have elapsed from the start of the first dimming signal transmission. Since the dimming signal cannot be transmitted for a certain period of time, the dimming signal is lost, and there is a problem that the user may misunderstand that the remote control device or the lighting control device is out of order.
JP-A-5-76064

請求項２の発明は、請求項１に記載の無線式調光制御システムにおいて、前記第３所定時間は、特定小電力無線通信方式の規格で定められた送信禁止期間と同じ時間であることを特徴とする。   According to a second aspect of the present invention, in the wireless dimming control system according to the first aspect, the third predetermined time is the same time as a transmission prohibition period defined in the standard of the specific low power wireless communication system. Features.

請求項１の発明によれば、ユーザによる調光アップボタン又は調光ダウンボタンなどの操作部の操作が比較的速く、特定小電力無線通信方式の規格（ＳＴＤ−Ｔ６７など）における送信可能時間（例えば５秒）以内に調光制御が完了できる場合、すなわち、送信部が前記調光信号の送信を完了してから第２回目の第１操作又は第２操作がなされるまでの操作間隔が第２所定時間以内であるときは、操作部が第１操作又は第２操作されるたびに、信号発生部は直ちに調光信号を発生し、送信部を介して調光制御装置に送信する（従来例と同様の調光制御）。それに対して、ユーザによる調光アップボタン又は調光ダウンボタンなどの操作部の操作が比較的遅く、特定小電力無線通信方式の規格（ＳＴＤ−Ｔ６７など）における送信可能時間（例えば５秒）以内に調光制御が完了できそうにない場合、すなわち、上記操作間隔が第２所定時間よりも長いときは、送信部が調光信号の送信を完了してから第３所定時間（例えば２秒）経過したときに新たな調光信号を発生し、送信部を介して送信する。それによって、ユーザによる調光アップボタン又は調光ダウンボタンの操作などに応じて調光信号の送信間隔を制御することができ、照明装置の調光レベルをユーザの操作に合わせて自然に変化させることができる。   According to the first aspect of the present invention, the operation of the operation unit such as the dimming up button or the dimming down button by the user is relatively fast, and the transmission possible time (STD-T67, etc.) For example, if the dimming control can be completed within 5 seconds), that is, the operation interval from when the transmission unit completes the transmission of the dimming signal until the second first operation or second operation is performed is 2 When the time is within the predetermined time, each time the operation unit is operated for the first operation or the second operation, the signal generation unit immediately generates a dimming signal and transmits it to the dimming control device via the transmission unit (conventional). Dimming control similar to the example). On the other hand, the operation of the operation unit such as the dimming up button or the dimming down button by the user is relatively slow, and within the transmission possible time (for example, 5 seconds) in the standard of the specific low power wireless communication system (STD-T67 etc.) When the dimming control is unlikely to be completed, that is, when the operation interval is longer than the second predetermined time, a third predetermined time (for example, 2 seconds) after the transmitter completes the transmission of the dimming signal. When the time has elapsed, a new dimming signal is generated and transmitted via the transmission unit. Thereby, the transmission interval of the dimming signal can be controlled according to the operation of the dimming up button or dimming down button by the user, and the dimming level of the lighting device is naturally changed according to the user's operation. be able to.

請求項２の発明によれば、第３所定時間を特定小電力無線通信方式の規格で定められた送信禁止期間と同じ時間とすることにより、信号発生部が調光信号を発生する時点では、送信部は必ず送信可能な状態になっており、調光信号の失報を防止することができる。   According to the invention of claim 2, by setting the third predetermined time to be the same time as the transmission prohibition period defined in the standard of the specific low power wireless communication system, at the time when the signal generating unit generates the dimming signal, The transmission unit is always in a transmittable state, and can prevent the dimming signal from being lost.

本発明の一実施形態に係る無線式調光制御システムについて、図面を参照しつつ説明する。図１に示すように、本実施形態に係る無線式調光制御システム１は、ユーザによって操作される遠隔操作装置１０と、遠隔操作装置１０から送信される信号を受信して、受信した信号の示す内容に応じて照明装置３０を調光制御する（照明のオン／オフを含む）調光制御装置２０で構成されている。調光制御装置２０は、照明装置３０の制御回路（例えばインバータ回路）と共に一体的に構成されていてもよいし、照明装置３０とは独立して構成され、複数の照明装置３０を同時に調光制御するものであってもよい。遠隔操作装置１０は、従来から用いられている赤外線を信号の送受信に用いるものであってもよいが、特定小電力無線通信方式の規格（ＳＴＤ−Ｔ６７）による電波通信を用いたものであることが好ましい。   A wireless dimming control system according to an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the wireless dimming control system 1 according to the present embodiment receives a remote operation device 10 operated by a user and a signal transmitted from the remote operation device 10, and receives the received signal. The light control device 20 includes a light control device 20 that controls light control (including lighting on / off) according to the contents to be shown. The dimming control device 20 may be configured integrally with a control circuit (for example, an inverter circuit) of the lighting device 30 or may be configured independently of the lighting device 30 and simultaneously control the plurality of lighting devices 30. It may be controlled. The remote operation device 10 may use infrared rays that have been conventionally used for signal transmission / reception, but uses radio communication according to the standard (STD-T67) of the specific low-power wireless communication system. Is preferred.

遠隔操作装置１０は、ユーザにより操作され、照明装置の点灯及び消灯を制御する点灯ボタン（例えば、◎ボタン）及び消灯ボタン（例えば、□ボタン）、調光レベルを高くするための調光アップボタン（例えば、△ボタン）及び調光レベルを低くするための調光ダウンボタン（例えば、▽ボタン）などの複数のスイッチで構成された操作部１１と、操作部１１が操作されたときに、所定の調光信号を発生させるＣＰＵ、ＲＯＭ、ＲＡＭなどで構成された信号発生部１２と、所定の調光信号を変調して送信する赤外線ＬＥＤなどの発光素子又は所定の周波数の電波を発振する発振回路などで構成された送信部１３などを備えている。なお、遠隔操作装置１０は、必ずしもリモコン装置のようにユーザが手持ちで操作できるものに限られず、壁面に設けられた操作パネルなどであってもよい。   The remote operation device 10 is operated by a user, and a lighting button (for example, ◎ button) and a light-off button (for example, □ button) for controlling turning on and off of the lighting device, and a light control up button for increasing the light control level. (For example, a Δ button) and a light control down button (for example, a ▽ button) for lowering the light control level, and an operation unit 11 configured with a plurality of switches, and a predetermined time when the operation unit 11 is operated. A signal generator 12 composed of a CPU, ROM, RAM, etc. that generates a dimming signal, and a light emitting element such as an infrared LED that modulates and transmits a predetermined dimming signal or an oscillation that oscillates a radio wave of a predetermined frequency A transmission unit 13 composed of a circuit or the like is provided. The remote operation device 10 is not necessarily limited to a device that can be operated by a user, such as a remote control device, and may be an operation panel provided on a wall surface.

調光制御装置２０は、送信部１３から送信された所定の調光信号を受信する受光素子又はアンテナ及び復調機などで構成された受信部２１と、受信した調光信号に応じて調光制御を行うＣＰＵ、ＲＯＭ、ＲＡＭなどで構成された調光制御部２２と、ユーザにより操作され、遠隔操作装置１０を介さずに直接調光制御するための操作部２３などを備えている。なお、照明装置３０は、必ずしもこの無線式調光制御システムに含まれている必要はない。   The dimming control device 20 includes a light receiving element or an antenna that receives a predetermined dimming signal transmitted from the transmitting unit 13, an antenna, a demodulator, and the like, and dimming control according to the received dimming signal. A light control unit 22 composed of a CPU, a ROM, a RAM, and the like, and an operation unit 23 that is operated by a user and directly controls light without using the remote operation device 10. The lighting device 30 is not necessarily included in the wireless dimming control system.

図２及び図３は、本実施形態に係る無線式調光制御システム１における２つの調光制御動作パターンを示すタイムチャートである。この無線式調光制御システム１では、ユーザによる操作部１１の調光アップボタン又は調光ダウンボタンなどの操作間隔ΔＴが、あらかじめ設定された第２所定時間Ｔ２以内か、あるいは第２所定時間Ｔ２よりも長いかによって、調光信号Ｓ１の送信のタイミングを変化させるように構成されている。   2 and 3 are time charts showing two dimming control operation patterns in the wireless dimming control system 1 according to the present embodiment. In the wireless dimming control system 1, the operation interval ΔT of the dimming up button or dimming down button of the operation unit 11 by the user is within a preset second predetermined time T2, or the second predetermined time T2. The transmission timing of the dimming signal S1 is changed depending on whether it is longer.

遠隔操作装置１０の信号発生部１２は、ユーザにより操作部１１が照明装置３０の調光レベルを高くするための最初の第１操作Ｍ１又は調光レベルを低くするための最初の第２操作Ｍ２がなされると、その最初の第１操作Ｍ１又は第２操作Ｍ２に応じて、照明装置３０の調光レベルを現在の調光レベルよりも１段高く又は低くするための調光信号を発生し、送信部１３は、第１所定時間Ｔ１だけ調光信号Ｓ１を変調して送信する。この時点では、ユーザによる調光アップボタン又は調光ダウンボタンなどの操作部１１の操作が速いか遅いか不明であるため、操作部１１が操作されると直ちに調光信号Ｓ１を発生し、送信する。   The signal generation unit 12 of the remote operation device 10 causes the user to perform the first first operation M1 for the operation unit 11 to increase the dimming level of the lighting device 30, or the first second operation M2 for lowering the dimming level. Is performed, a dimming signal is generated to make the dimming level of the lighting device 30 one level higher or lower than the current dimming level in accordance with the first first operation M1 or the second operation M2. The transmitter 13 modulates and transmits the dimming signal S1 for the first predetermined time T1. At this time, since it is unknown whether the operation of the operation unit 11 such as the dimming up button or the dimming down button by the user is fast or slow, the dimming signal S1 is generated and transmitted immediately when the operation unit 11 is operated. To do.

次に、ユーザにより操作部１１が第２回目の第１操作Ｍ１’又は第２操作Ｍ２’がなされると、調光制御部２２は、１３送信部が前回の調光信号Ｓ１の送信を完了してから第２回目の第１操作Ｍ１’又は第２操作Ｍ２’がなされるまでの操作間隔ΔＴを第２所定時間Ｔ２と比較する。ここで、操作間隔ΔＴが第２所定時間Ｔ２以内（ΔＴ≦Ｔ２）であるときは、ユーザによる調光アップボタン又は調光ダウンボタンなどの操作部１１の操作が比較的速く、特定小電力無線通信方式の規格（ＳＴＤ−Ｔ６７など）における送信可能時間（例えば５秒）以内に調光制御が完了できると予想される場合である。従って、図２に示すように、信号発生部１２は、従来例と同様に、直ちに新たな調光信号Ｓ１’を発生し、送信部１３を介して調光制御装置２０に調光信号Ｓ１’を送信する。   Next, when the operation unit 11 performs the second first operation M1 ′ or the second operation M2 ′ by the user, the dimming control unit 22 completes the transmission of the previous dimming signal S1 by the 13 transmitting unit. Then, the operation interval ΔT until the second first operation M1 ′ or the second operation M2 ′ is performed is compared with the second predetermined time T2. Here, when the operation interval ΔT is within the second predetermined time T2 (ΔT ≦ T2), the operation of the operation unit 11 such as the dimming up button or the dimming down button by the user is relatively fast, and the specific low power wireless This is a case where the dimming control is expected to be completed within the transmission possible time (for example, 5 seconds) in the communication system standard (STD-T67 or the like). Therefore, as shown in FIG. 2, the signal generation unit 12 immediately generates a new dimming signal S1 ′ and transmits the dimming signal S1 ′ to the dimming control device 20 via the transmission unit 13, as in the conventional example. Send.

一方、上記操作間隔ΔＴが第２所定時間Ｔ２よりも長いとき（ΔＴ＞Ｔ２）は、ユーザによる調光アップボタン又は調光ダウンボタンなどの操作部の操作が比較的遅く、特定小電力無線通信方式の規格（ＳＴＤ−Ｔ６７など）における送信可能時間（例えば５秒）以内に調光制御が完了できそうにない場合である。従って、図３に示すように、送信部１３が調光信号Ｓ１の送信を完了してから第３所定時間Ｔ３（例えば２秒）経過したときに新たな調光信号Ｓ１’を発生し、送信部１３を介して調光制御装置２０に調光信号Ｓ１’を送信する。   On the other hand, when the operation interval ΔT is longer than the second predetermined time T2 (ΔT> T2), the operation of the operation unit such as the dimming up button or the dimming down button by the user is relatively slow, and the specific low power wireless communication This is a case in which the dimming control is unlikely to be completed within the transmission possible time (for example, 5 seconds) in the system standard (STD-T67 or the like). Therefore, as shown in FIG. 3, a new dimming signal S1 ′ is generated and transmitted when a third predetermined time T3 (for example, 2 seconds) elapses after the transmission unit 13 completes the transmission of the dimming signal S1. The dimming signal S1 ′ is transmitted to the dimming control device 20 via the unit 13.

ここで、操作間隔ΔＴと比較される第２所定時間Ｔ２及び第３所定時間Ｔ３について説明する。図２に示すような操作間隔ΔＴが短い場合、特定小電力無線通信方式の規格（ＳＴＤ−Ｔ６７など）における送信可能時間（例えば５秒）以内に調光制御を完了させる必要がある。そこで、調光制御装置２０による照明装置３０の調光段数をＮ、調光信号Ｓ１の送信時間（すなわち第１所定時間）をＴ１とすると、第２所定時間Ｔ２は以下の式で表される。
Ｔ２＝（５秒−Ｔ１×Ｎ）／（Ｎ−１） Here, the second predetermined time T2 and the third predetermined time T3 compared with the operation interval ΔT will be described. When the operation interval ΔT as shown in FIG. 2 is short, it is necessary to complete the dimming control within the transmittable time (for example, 5 seconds) in the standard (STD-T67 or the like) of the specific low power wireless communication system. Therefore, when the light control stage number of the lighting device 30 by the light control device 20 is N and the transmission time of the light control signal S1 (that is, the first predetermined time) is T1, the second predetermined time T2 is expressed by the following equation. .
T2 = (5 seconds−T1 × N) / (N−1)

操作間隔ΔＴが第２所定時間Ｔ２以内である場合、照明装置３０の調光レベルを最低レベルから最高レベルに又はその逆に変化させても上記送信可能時間内に調光制御を完了することができる。逆に、操作間隔ΔＴが第２所定時間Ｔ２よりも長い場合、照明装置３０の調光レベルを最低レベルから最高レベルに又はその逆に変化させると、上記送信可能時間内に調光制御を完了させることはできず、調光信号が途中で遮断されてしまう。   When the operation interval ΔT is within the second predetermined time T2, the dimming control can be completed within the transmittable time even if the dimming level of the lighting device 30 is changed from the lowest level to the highest level or vice versa. it can. On the contrary, when the operation interval ΔT is longer than the second predetermined time T2, the dimming control is completed within the transmittable time by changing the dimming level of the lighting device 30 from the lowest level to the highest level or vice versa. Therefore, the dimming signal is interrupted on the way.

一方、特定小電力無線通信方式の規格（ＳＴＤ−Ｔ６７など）では、信号の送信完了後、所定の送信可能時間（例えば５秒）が経過していなくても、送信禁止期間（例えば２秒）が経過していれば、新たな信号の送信が可能になる。従って、第３所定時間Ｔ３を、特定小電力無線通信方式の規格で定められた送信禁止期間（例えば２秒）と同じ時間とすることにより、信号発生部１２が調光信号Ｓ１’を発生する時点では、送信部１３は必ず送信可能な状態になっており、調光信号Ｓ１’の失報を防止することができる。 On the other hand, in specific low-power wireless communication system standards (STD-T67 and the like), even if a predetermined transmittable time (for example, 5 seconds) has not elapsed after completion of signal transmission, a transmission prohibited period (for example, 2 seconds) If elapses, a new signal can be transmitted. Therefore, the third predetermined time T3, by the same time as the specific low-power radio communication system transmission prohibition period specified in the standard (e.g., 2 seconds), the signal generator 12 is dimming signal S1 'generated At this point, the transmission unit 13 is always in a transmittable state and can prevent misreporting of the dimming signal S1 ′.

なお、調光信号Ｓ１及びＳ１’は、少なくとも、調光アップか調光ダウンかの情報及び調光段数の情報を含んでおり、その他の情報を含んでいてもよい。例えば、無線式調光制御システム１が複数の遠隔操作装置１０及び複数の調光制御装置２０で構成されている場合は、各調光制御装置２０及び照明装置３０に識別番号を設定し、遠隔操作装置１０から送信される調光信号Ｓ１に識別番号を付与することにより、各遠隔操作装置１０から、任意の調光制御装置２０に接続された全ての照明装置３０又は任意の照明装置３０を特定して、調光制御することが可能である。   The dimming signals S1 and S1 'include at least information on whether dimming is up or down and information on the number of dimming stages, and may include other information. For example, when the wireless dimming control system 1 is composed of a plurality of remote control devices 10 and a plurality of dimming control devices 20, an identification number is set for each dimming control device 20 and the lighting device 30, and remote control is performed. By assigning an identification number to the dimming signal S1 transmitted from the operation device 10, all the illuminating devices 30 or arbitrary illuminating devices 30 connected to any dimming control device 20 from each remote control device 10 are displayed. Specifically, dimming control can be performed.

このように、本発明によれば、ユーザによる操作部１１の調光アップボタン又は調光ダウンボタンなどの操作間隔ΔＴが、あらかじめ設定された第２所定時間Ｔ２以内か、あるいは第２所定時間Ｔ２よりも長いかによって、調光信号Ｓ１の送信のタイミングを変化させるように構成しているので、照明装置の調光レベルをユーザの操作に合わせて自然に変化させることができる。また、調光信号Ｓ１、Ｓ１’の送受信に特定小電力無線通信方式の規格で定められた電波を用いた場合に、第３所定時間Ｔ３を特定小電力無線通信方式の規格で定められた送信禁止期間と同じ時間とすることにより、信号発生部が調光信号を発生する時点では、送信部は必ず送信可能な状態になっており、調光信号の失報を防止することができる。   As described above, according to the present invention, the operation interval ΔT of the dimming up button or the dimming down button of the operation unit 11 by the user is within the preset second predetermined time T2 or the second predetermined time T2. Since the transmission timing of the dimming signal S1 is changed depending on whether it is longer, the dimming level of the lighting device can be naturally changed according to the user's operation. In addition, when radio waves defined by the specific low power wireless communication standard are used for transmission and reception of the dimming signals S1, S1 ′, the third predetermined time T3 is transmitted according to the specific low power wireless communication standard. By setting the same time as the prohibition period, when the signal generating unit generates the dimming signal, the transmitting unit is always in a transmittable state, and the misreporting of the dimming signal can be prevented.
