Description

本発明は、照明制御システムに関するものである。   The present invention relates to a lighting control system.

従来より、それぞれ個別の論理アドレスを割り当てられた複数の照明器具と、複数の照明器具と伝送線を介して接続されたコントローラからなる照明制御システムがあり、タイムスケジュール、スイッチ操作、センサ入力などに応じて、コントローラが制御対象となる照明器具の論理アドレスを含む伝送信号を送信することで、その論理アドレスが割り当てられた照明器具の点灯・消灯・調光レベルの変更といった制御が行われる。   Conventionally, there is a lighting control system consisting of a plurality of lighting fixtures each assigned an individual logical address and a controller connected to the plurality of lighting fixtures via a transmission line. For time schedules, switch operations, sensor inputs, etc. In response, the controller transmits a transmission signal including the logical address of the lighting fixture to be controlled, thereby performing control such as turning on / off the lighting fixture to which the logical address is assigned and changing the dimming level.

この種の照明制御システムにおいては、各照明器具に割り当てられた論理アドレスをコントローラに予め設定しておく必要があり、例えば、照明器具に論理アドレスを明記したシールを貼るなどして照明器具の論理アドレスを施工者が把握できるようにし、論理アドレスと施工場所との関係が図示された施工図面に基づいて施工者が照明器具を配設した後、コントローラにリモコン等を用いて各照明器具の論理アドレスを設定するといった方法が考えられる。   In this type of lighting control system, it is necessary to set in advance a logical address assigned to each lighting fixture in the controller. For example, a logical label of the lighting fixture is attached to the lighting fixture. After the installer has installed the lighting fixtures based on the construction drawing that shows the relationship between the logical address and the construction location so that the installer can grasp the addresses, the logic of each lighting fixture is used using a remote controller etc. A method such as setting an address is conceivable.

このようにすれば、各照明器具はコントローラからの伝送信号が受信できれば良いので、比較的安価なＣＰＵを用いることが可能であるが、照明器具に割り当てられた論理アドレスの管理、論理アドレスを明記したシールなどの貼り付けなどの管理コストや、施工図面の作成及び施工時論理アドレスの確認に手間がかかっていた。   In this way, each luminaire only needs to be able to receive a transmission signal from the controller, so it is possible to use a relatively inexpensive CPU. However, the management of logical addresses assigned to the luminaires and the logical addresses are clearly specified. It took time and effort to check the management costs such as pasting stickers, creating construction drawings, and checking logical addresses during construction.

そこで、論理アドレスをコントローラに予め設定する方法として、例えば特許文献１に記載されているように、コントローラが各照明器具に対して論理アドレスを要求する要求信号を出力し、各照明器具が要求信号に応じて自身の論理アドレスをコントローラに送信することで、コントローラに全ての照明器具の論理アドレスを設定する方法が提案されている。この方法を用いることで、施工者はコントローラのみをリモコンにより操作すれば良く、施工にかかる手間が大幅に低減される。   Therefore, as a method for presetting the logical address in the controller, for example, as described in Patent Document 1, the controller outputs a request signal for requesting a logical address to each lighting fixture, and each lighting fixture receives a request signal. In response to this, a method has been proposed in which the logical addresses of all lighting fixtures are set in the controller by transmitting its own logical address to the controller. By using this method, the installer only has to operate the controller with the remote controller, and the labor required for construction is greatly reduced.

特開平７−４６２５８号公報JP-A-7-46258

しかしながら、コントローラの要求信号に応じて全ての照明器具が一斉に論理アドレスを送信すると、通信ライン上で論理アドレスを含む信号が壊れたり、信号の波形が変形して、コントローラが誤った論理アドレスを取得するという可能性があった。   However, if all the lighting fixtures send a logical address all at once in response to a request signal from the controller, the signal containing the logical address is broken on the communication line, or the waveform of the signal is deformed, and the controller sets the wrong logical address. There was a possibility of getting.

この問題を回避する方法として、各照明器具がキャリアセンスを実行して論理アドレスを送信する方法が考えられるが、キャリアセンスを実行するためには、各照明器具に高価なＣＰＵを搭載する必要があり、製造コストが高くなるという問題があった。   As a method for avoiding this problem, a method in which each lighting fixture performs carrier sense and transmits a logical address is conceivable. However, in order to execute carrier sensing, it is necessary to mount an expensive CPU in each lighting fixture. There was a problem that the manufacturing cost was high.

また、他の回避方法として、各照明器具にリモコン受信部を設け、リモコンからの操作信号に応じて論理アドレスを送信する方法も考えられるが、全ての照明器具にリモコン受信部を設けると製造コストが高くなるとともに、施工者が全ての照明器具に対してリモコンにより操作する必要があるため、照明制御システムの規模が大きく、照明器具の数が多くなると、施工にかかる手間が非常に大きくなってしまうという問題もあった。   Another possible avoidance method is to provide a remote control receiver for each lighting fixture and send a logical address in response to an operation signal from the remote control. As the lighting control system is large and the number of lighting fixtures increases, the construction work becomes very large. There was also a problem of end.

本発明は、上記事由に鑑みて為されたものであり、その目的とするところは、論理アドレスをコントローラに設定する際の手間や時間を低減した、低コストの照明制御システムを提供することにある。   The present invention has been made in view of the above reasons, and an object of the present invention is to provide a low-cost lighting control system that reduces labor and time when setting a logical address in a controller. is there.

上記目的を達成するために、請求項１の発明では、個別の論理アドレスが割り当てられた複数の照明器具と、各々の前記照明器具に割り当てられた前記論理アドレスを用いて所望の前記照明器具を制御するコントローラとを備え、前記コントローラは、前記照明器具の前記論理アドレスを記憶する記憶部と、前記照明器具に前記論理アドレスを要求する要求信号を含む伝送信号を送信し、前記照明器具から送信される返送信号を受信する送受信部を有し、各々の前記照明器具は、前記要求信号を受信してから、自機に割り当てられた前記論理アドレスに対応した待機時間が経過した後、前記返送信号を送信し、前記コントローラは、前記返送信号の受信時間に基づいて前記論理アドレスを取得して前記記憶部に記憶させることを特徴とする。 To achieve the above object, in the invention of claim 1, a plurality of luminaires which are assigned separate logical address, the desired the luminaire using the logical address assigned to each of the luminaire and a controller for controlling, said controller transmits a storage unit that stores the logical address of the luminaire, the transmission signal including a request signal requesting the logical address to the luminaire, transmitted from the luminaire has a transceiver for receiving a return signal, each said luminaire of, after the receiving the request signal, wait time corresponding to the logical address assigned to the own apparatus has passed, before Symbol transmits a transmission signal return, the controller is characterized in that to be stored in the storage unit by obtaining the logical address based on a reception time of the return signal.

請求項２の発明では、請求項１記載の発明において、前記コントローラは、前記照明器具からの返送信号を受信すると、当該返信信号に含まれる論理アドレスと前記照明器具を点灯させる制御命令とを含む伝送信号を前記照明器具に送信することを特徴とする。   According to a second aspect of the present invention, in the first aspect of the invention, when the controller receives a return signal from the lighting fixture, the controller includes a logical address included in the reply signal and a control command for lighting the lighting fixture. A transmission signal is transmitted to the lighting fixture.

請求項１の発明によれば、要求信号を受信した複数の照明器具は、個別に割り当てられた論理アドレスに基づいた待機時間を経過後、返送信号を送信するので、各照明器具は返送信号を一斉に送信することが無くなり、通信ライン上で返送信号が壊れる可能性を低減できる。また、各照明器具には、リモコン受信部などの特別な装置を設ける必要が無く、低コストな照明制御システムを提供することができる。   According to the first aspect of the present invention, the plurality of lighting fixtures that have received the request signal transmit a return signal after elapse of the waiting time based on the individually assigned logical addresses, so that each lighting fixture receives the return signal. Transmission at the same time is eliminated, and the possibility that the return signal is broken on the communication line can be reduced. Moreover, it is not necessary to provide each lighting device with a special device such as a remote control receiver, and a low-cost lighting control system can be provided.

請求項２の発明によれば、コントローラが論理アドレスを取得した照明器具を視覚的に確認することが可能となり、また、全ての照明器具が点灯することで、コントローラが論理アドレスの取得を完了したことが確認できる。   According to the invention of claim 2, it is possible to visually confirm the lighting fixture from which the controller has obtained the logical address, and the controller has completed the acquisition of the logical address by turning on all the lighting fixtures. I can confirm that.

以下に本発明の実施の形態を図１〜図３に基づいて説明する。   Embodiments of the present invention will be described below with reference to FIGS.

本実施の形態にかかる照明制御システムは、図１に示すように、個別の論理アドレスが割り当てられた複数台の照明器具２（２ａ…２ｎ）と、各照明器具２の動作を制御するコントローラ１とが、通信線Ｌを介して接続されている。   As shown in FIG. 1, the lighting control system according to the present embodiment includes a plurality of lighting fixtures 2 (2a... 2n) to which individual logical addresses are assigned, and a controller 1 that controls the operation of each lighting fixture 2. Are connected via a communication line L.

コントローラ１は、コントローラ１全体の動作を統括的に制御するマイコンからなる制御部１１と、例えば揮発性のＳＲＡＭからなる記憶部１２と、通信線Ｌを介して各照明器具２との間で信号の授受を行う送受信部１３とを備える。   The controller 1 is a signal between the control unit 11 composed of a microcomputer that controls the overall operation of the controller 1, the storage unit 12 composed of, for example, a volatile SRAM, and each lighting fixture 2 via the communication line L. And a transmission / reception unit 13 that transmits and receives.

記憶部１２には、制御部１１によって、各照明器具２に割り当てられた論理アドレスが書き込まれ、制御部１１が必要に応じて論理アドレスの読み出しを行う。   The logical address assigned to each lighting fixture 2 by the control unit 11 is written in the storage unit 12, and the control unit 11 reads the logical address as necessary.

送受信部１３は、制御部１１からの制御信号を変調して伝送信号として通信線Ｌに出力するとともに、通信線Ｌを介して入力される伝送信号を復調して制御部１１に出力する。ここで、伝送信号としては、各照明器具２に論理アドレスの返送を要求するアドレス要求命令、各照明器具２の点灯・消灯・調光レベルの変更を行う制御命令などの各種命令がある。   The transmission / reception unit 13 modulates the control signal from the control unit 11 and outputs it as a transmission signal to the communication line L, and demodulates the transmission signal input via the communication line L and outputs the demodulated signal to the control unit 11. Here, the transmission signal includes various commands such as an address request command for requesting each luminaire 2 to return a logical address, and a control command for turning on / off each luminaire 2 and changing the dimming level.

また、コントローラ１は、リモコン及びリモコン受信部などの操作入力部（図示せず）を備えており、その操作入力に応じて、制御部１１が接続された各照明器具２に割り当てられた論理アドレスの取得を開始する。   In addition, the controller 1 includes operation input units (not shown) such as a remote controller and a remote control reception unit, and a logical address assigned to each luminaire 2 to which the control unit 11 is connected according to the operation input. Start getting.

照明器具２は、照明器具２全体の動作を統括的に制御するマイコンからなる制御部２１と、例えばＥＥＰＲＯＭ（Ｅｌｅｃｔｉｃａｌ Ｅｒａｓａｂｌｅ Ｐｒｏｇｒａｍａｎｌｅ ＲＯＭ）などの不揮発性のメモリからなる記憶部２２と、通信線Ｌを介してコントローラ１との間で信号の授受を行う送受信部２３と、例えばＬＥＤなどからなる光源に点灯電力を出力する点灯回路２４とを備える。   The luminaire 2 includes a control unit 21 that includes a microcomputer that controls the overall operation of the luminaire 2, a storage unit 22 that includes a nonvolatile memory such as an EEPROM (Electrical Erasable Program ROM), and a communication line L. A transmission / reception unit 23 that exchanges signals with the controller 1 and a lighting circuit 24 that outputs lighting power to a light source such as an LED.

記憶部２２には、照明器具の論理アドレスが予め記憶されており、制御部２１が必要に応じて読み出しを行う。この論理アドレスは、各照明器具２ａ…２ｎの間で重複しない値に設定されている。   The storage unit 22 stores in advance the logical address of the luminaire, and the control unit 21 reads it out as necessary. This logical address is set to a value that does not overlap between the respective lighting fixtures 2a.

送受信部２３は、通信線Ｌを介して受信した伝送信号に含まれる論理アドレスが、自身の論理アドレスを対象としたものであるかを判断し、自身の論理アドレスが対象となっていれば、この伝送信号に含まれる各種命令を制御部２１に出力する。また送受信部２３は、制御部２１が出力する各種情報とともに、自機に割り当てられている論理アドレスを含めて送信を行う。   The transmission / reception unit 23 determines whether the logical address included in the transmission signal received via the communication line L is intended for its own logical address, and if its own logical address is targeted, Various commands included in the transmission signal are output to the control unit 21. In addition, the transmission / reception unit 23 performs transmission including various information output from the control unit 21 together with the logical address assigned to the own device.

ここで、本実施の形態にかかる照明器具の初期設定として、コントローラ１が通信線Ｌを介して接続された各照明器具２の論理アドレスを取得する方法について説明を行う。   Here, as an initial setting of the lighting fixture according to the present embodiment, a method in which the controller 1 acquires the logical address of each lighting fixture 2 connected via the communication line L will be described.

まず、コントローラ１及び各照明器具２を施工後、使用者はリモコン（図示せず）などを用いて、コントローラ１が各照明器具２の論理アドレスの取得を開始するための制御信号をコントローラ１に送信する。   First, after constructing the controller 1 and each lighting fixture 2, the user uses a remote controller (not shown) or the like to send a control signal to the controller 1 for the controller 1 to start acquiring the logical address of each lighting fixture 2. Send.

コントローラ１の制御部１１は、上述の制御信号に応じて、全ての照明器具２を対象とし、各照明器具２の論理アドレスの返送を要求するアドレス要求命令を含む伝送信号Ｓ１を送信する（図２（ａ）を参照）。   The controller 11 of the controller 1 transmits a transmission signal S1 including an address request command for requesting the return of the logical address of each lighting fixture 2 for all the lighting fixtures 2 in accordance with the control signal described above (see FIG. 2 (a)).

各照明器具２は、伝送信号Ｓ１を受信すると、自機に割り当てられた論理アドレスに応じた待機時間が経過した後、自機に割り当てられた論理アドレスを含む返送信号Ｓ２を、コントローラ１に返送する。ここで返送信号Ｓ２を、５ｍｓのパルス波とし、各照明器具２の待機時間を論理アドレスを示す数値×１０ｍｓを待機時間とすることで、コントローラ１は受信した返送信号Ｓ２から、各照明器具２に割り当てられた論理アドレスを取得することができる。   Upon receiving the transmission signal S1, each luminaire 2 returns a return signal S2 including the logical address assigned to the own device to the controller 1 after the standby time corresponding to the logical address assigned to the own device has elapsed. To do. Here, the return signal S2 is a pulse wave of 5 ms, and the waiting time of each lighting fixture 2 is a numerical value indicating the logical address × 10 ms as the waiting time, so that the controller 1 determines each lighting fixture 2 from the received return signal S2. The logical address assigned to can be acquired.

例えば、照明器具２ａ、２ｂ、２ｃ、２ｄに割り当てられた論理アドレスがそれぞれ２３、５１、７、１２２とすると、照明器具２ａ、２ｂ、２ｃ、２ｄの待機時間はそれぞれ２３０ｍｓ、５１０ｍｓ、７ｍｓ、１２２０ｍｓとなる。各照明器具２ａ、２ｂ、２ｃ、２ｄは、それぞれの待機時間だけ待機した後、５ｍｓのパルス波からなる返送信号Ｓ２をコントローラ１に出力する（図２（ｂ）を参照）。   For example, if the logical addresses assigned to the lighting fixtures 2a, 2b, 2c, and 2d are 23, 51, 7, and 122, respectively, the waiting times of the lighting fixtures 2a, 2b, 2c, and 2d are 230 ms, 510 ms, 7 ms, and 1220 ms, respectively. It becomes. Each of the lighting fixtures 2a, 2b, 2c, and 2d outputs a return signal S2 composed of a 5 ms pulse wave to the controller 1 after waiting for the respective standby time (see FIG. 2B).

これにより、コントローラ１は、図３のように、アドレス要求命令を含む伝送信号Ｓ１を送信した後（図３のｔ０）、７０ｍｓ、２３０ｍｓ、５１０ｍｓ、１２２０ｍｓで５ｍｓのパルス波からなる返送信号Ｓ２を受信する。コントローラ１は、受信した時間に応じて、論理アドレスが７、２３、５１、１２２の論理アドレスが割り当てられた照明器具２が接続されていることを検知することができ、制御部１１が記憶部１２に７、２３、５１、１２２の値を記憶させる。   As a result, as shown in FIG. 3, the controller 1 transmits a transmission signal S1 including an address request command (t0 in FIG. 3), and then returns a return signal S2 consisting of a pulse wave of 5 ms at 70 ms, 230 ms, 510 ms, and 1220 ms. Receive. The controller 1 can detect that the luminaire 2 to which the logical addresses of 7, 23, 51, 122 are assigned is connected according to the received time, and the control unit 11 stores the storage unit. 12 stores the values of 7, 23, 51, and 122.

その後、例えば、アドレス要求命令を含む伝送信号Ｓ１を送信してから制御部１１に予め設定された所定時間が経過すると、コントローラ１は全ての論理アドレスを取得したものとして論理アドレスの収集を停止し、使用者によるリモコンなどの操作に応じて、各照明器具２の点灯・消灯などの制御を行う。   Thereafter, for example, when a predetermined time set in the control unit 11 elapses after the transmission signal S1 including the address request command is transmitted, the controller 1 stops collecting the logical addresses as if all the logical addresses have been acquired. Depending on the operation of the remote controller or the like by the user, the lighting fixtures 2 are controlled to be turned on / off.

このようにして、各照明器具２はコントローラ１からのアドレス要求命令を含む伝送信号Ｓ１に応じて、それぞれ異なる待機時間だけ待機後、パルス波からなる返送信号Ｓ２を送信するので、通信線Ｌ上で論理アドレスを含む信号が壊れたり、信号の波形が変形して、コントローラ１が誤った論理アドレスを取得するという可能性を低減することができる。また、個々の照明器具２には、リモコン受信部などの装置を搭載する必要が無く、論理アドレスをコントローラ１に設定する際の手間や時間を低減するとともに、低コストの照明制御システムを提供することができる。   In this way, each luminaire 2 transmits a return signal S2 consisting of a pulse wave after waiting for a different waiting time in accordance with the transmission signal S1 including an address request command from the controller 1, and thus on the communication line L. Thus, it is possible to reduce the possibility that the signal including the logical address is broken or the waveform of the signal is deformed so that the controller 1 acquires an incorrect logical address. Moreover, it is not necessary to mount a device such as a remote control receiver in each lighting fixture 2, and it is possible to reduce labor and time when setting a logical address in the controller 1, and to provide a low-cost lighting control system. be able to.

なお、コントローラ１は、伝送信号Ｓ１を送信後、パルス波からなる返送信号Ｓ２を受信する毎に、返送信号Ｓ２の受信時間から求めた論理アドレスを制御対象とし、照明器具２を点灯する点灯制御命令を含む伝送信号を送信するようにしてもよい。このようにすれば、コントローラ１が論理アドレスを取得した照明器具２を視覚的に確認することが可能となり、また、全ての照明器具２が点灯することで、コントローラ１が論理アドレスの取得を完了したことが確認することができる。   Note that each time the controller 1 receives the return signal S2 composed of a pulse wave after transmitting the transmission signal S1, the controller 1 controls the logical address obtained from the reception time of the return signal S2, and controls the lighting device 2 to turn on the lighting fixture 2. A transmission signal including a command may be transmitted. If it does in this way, it will become possible to confirm visually the lighting fixture 2 from which the controller 1 acquired the logical address, and the controller 1 completes acquisition of a logical address because all the lighting fixtures 2 light up. It can be confirmed.

また上記のように動作することで、使用者が全ての照明器具２が点灯したことを確認したうえでリモコンを操作することによって、コントローラ１が論理アドレスの収集を停止するようにしてもよい。   In addition, by operating as described above, the controller 1 may stop collecting the logical addresses by operating the remote controller after the user confirms that all the luminaires 2 are turned on.

なお、本実施の形態においては、返送信号Ｓ２を５ｍｓのパルス波とし、待機時間を論理アドレスの示す数値×１０ｍｓとしているが、前記内容に限定するものではなく、照明制御システムの規模や配線に応じて、適宜設定することができる。   In this embodiment, the return signal S2 is a pulse wave of 5 ms and the standby time is a numerical value indicated by the logical address × 10 ms. However, the present invention is not limited to the above contents, and the scale and wiring of the lighting control system are not limited. Accordingly, it can be set as appropriate.
