First, when the power supply of the lighting control system according to the first embodiment is turned on (step S1), the transmission unit 41 of the lighting control device 4 sequentially transmits information acquisition request signals to the terminal device 2 and each receiving device 3 ( Step S2). In the terminal device 2, when the transmission unit 22 receives the information acquisition request signal from the lighting control device 4, it returns a type signal to the lighting control device 4 under the control of the terminal device control unit 23. Similarly, in each receiving device 3, when the transmission unit 31 receives the information acquisition request signal from the lighting control device 4, the type signal is returned to the lighting control device 4 under the control of the receiving device control unit 32 (step S3). After the illumination control device 4 receives the type signal from the terminal device 2 and each receiving device 3, the illuminance information acquisition request signal is transmitted to the terminal device 2 whose sensor type is “illuminance sensor” (step S4).

端末器2では、伝送部22が照度情報取得リクエスト信号を受信すると、端末器制御部23が照度センサ20の照度計測結果を取得し、赤外線送信部21を制御して現在の照度計測結果及び目標照度値の情報を赤外線信号で送信する(ステップS5)。各受信装置3では、受光センサ30が端末器2からの赤外線信号を受光すると、受信装置制御部32が伝送部31を制御して受信信号を照明制御装置4に送信する(ステップS6)。   In the terminal device 2, when the transmission unit 22 receives the illuminance information acquisition request signal, the terminal device control unit 23 acquires the illuminance measurement result of the illuminance sensor 20 and controls the infrared transmission unit 21 to control the current illuminance measurement result and the target. Information on the illuminance value is transmitted as an infrared signal (step S5). In each receiving device 3, when the light receiving sensor 30 receives an infrared signal from the terminal device 2, the receiving device control unit 32 controls the transmission unit 31 and transmits the received signal to the illumination control device 4 (step S6).

照明制御装置4では、伝送部41が各受信装置3から受信信号を受信すると、位置特定部42が各受信装置3の位置情報と赤外線信号の大きさから端末器2の位置を特定し、調光部43が端末器2の位置情報、照度計測結果及び目標照度値から調光制御パラメータを算出する。その後、調光部43の制御によって、調光信号送信部44は上記調光制御パラメータを含む調光信号を照明装置1に送信する(ステップS7)。   In the lighting control device 4, when the transmission unit 41 receives a reception signal from each receiving device 3, the position specifying unit 42 specifies the position of the terminal 2 from the position information of each receiving device 3 and the magnitude of the infrared signal, and adjusts the position. The light unit 43 calculates the dimming control parameter from the position information of the terminal device 2, the illuminance measurement result, and the target illuminance value. Thereafter, the dimming signal transmitter 44 transmits a dimming signal including the dimming control parameter to the lighting device 1 under the control of the dimmer 43 (step S7).

照明装置1では、調光信号受信部11が調光信号を受信すると、負荷制御部12が調光信号の内容に基づいて照明負荷10の輝度を調整する(ステップS8)。このような動作を照明制御システムの電源がオフなるまで続ける(ステップS9)。   In the lighting device 1, when the dimming signal receiving unit 11 receives the dimming signal, the load control unit 12 adjusts the luminance of the lighting load 10 based on the content of the dimming signal (step S8). Such an operation is continued until the illumination control system is turned off (step S9).

以上、実施形態1によれば、端末器2の位置特定のために赤外線信号を用いることによって、電波を用いる場合に比べて指向性を高めることができ、端末器2の位置を精度よく特定することができる。これにより、端末器2の位置での照度が目標照度に精度よく近づくように各照明装置1の照明負荷10を調光制御することができる。   As described above, according to the first embodiment, by using the infrared signal for specifying the position of the terminal device 2, the directivity can be improved as compared with the case of using radio waves, and the position of the terminal device 2 can be specified with high accuracy. be able to. Thereby, dimming control of the illumination load 10 of each illuminating device 1 can be carried out so that the illumination intensity in the position of the terminal device 2 may approach the target illumination intensity accurately.

(Embodiment 4)
The illumination control system of Embodiment 4 includes a plurality of terminals 2 as shown in FIG. 5, and the terminal controller 23 of each terminal 2 distinguishes it from infrared signals transmitted from other terminals 2. Therefore, it has a transmission pattern control function for controlling the transmission pattern of the infrared signal transmitted from the infrared transmission unit 21, and the reception device control unit 32 of each reception device 3 transmits the infrared signal received by the light receiving sensor 30. This is different from the first embodiment in that each pattern is distinguished. In addition, about the component similar to Embodiment 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.

本実施形態の各端末器2では、図1に示す端末器制御部23が、単位時間あたりのパルス数を変更することで複数の送信パターンを赤外線送信部21に生成させることができる。例えば単位時間あたりに4つのパルスを有するもの、2つのパルスを有するもの、1つのパルスを有するものなどによって、複数の送信パターンを生成させることができる。   In each terminal device 2 of the present embodiment, the terminal control unit 23 shown in FIG. 1 can cause the infrared transmission unit 21 to generate a plurality of transmission patterns by changing the number of pulses per unit time. For example, a plurality of transmission patterns can be generated by having four pulses per unit time, having two pulses, having one pulse, or the like.

また、本実施形態の端末器2には、使用者Pが送信パターンを切り替えるために、筐体24(図3参照)の表面に露出させた操作部を有する切替スイッチ(図示せず)が設けられている。使用者Pは切替スイッチの操作部を操作することによって、端末器2ごとに異なる送信パターンに切り替えることができる。   Further, the terminal device 2 of the present embodiment is provided with a changeover switch (not shown) having an operation unit exposed on the surface of the casing 24 (see FIG. 3) in order for the user P to change the transmission pattern. It has been. The user P can switch to a different transmission pattern for each terminal device 2 by operating the operation part of the changeover switch.

各受信装置3の受信装置制御部32は、受光センサ30で受光された赤外線信号を送信パターンごとに区別し、伝送部31に対して、送信パターン情報を追加した受信信号を照明制御装置4に送信するように制御する。   The reception device control unit 32 of each reception device 3 distinguishes the infrared signal received by the light receiving sensor 30 for each transmission pattern, and sends the reception signal with the transmission pattern information added to the illumination control device 4 to the transmission unit 31. Control to send.

照明制御装置4の位置特定部42は、伝送部41が各受信装置3から受信信号を受信すると、受信信号に含まれている送信パターン情報ごとに、実施形態1と同様の動作を行い、各端末器2の位置を特定する。   When the transmission unit 41 receives a reception signal from each reception device 3, the position specifying unit 42 of the illumination control device 4 performs the same operation as that of the first embodiment for each transmission pattern information included in the reception signal. The position of the terminal device 2 is specified.

以上、本実施形態によれば、複数台の端末器2,・・・を備える場合に、端末器2ごとに異なる送信パターンを対応させることができるので、端末器2ごとに位置を特定して各照明装置1の照明負荷10の照度を制御することができる。   As described above, according to the present embodiment, when a plurality of terminals 2,... Are provided, different transmission patterns can be associated with each terminal 2. Therefore, the position is specified for each terminal 2. The illuminance of the lighting load 10 of each lighting device 1 can be controlled.

なお、実施形態3又は4の変形例として、実施形態2のように、端末器2の端末器制御部23が、赤外線送信部21から送信される赤外線信号の強度を制御する信号強度制御機能を有するものであってもよい。このような構成によれば、実施形態3又は4の効果を奏しながら、受光センサ30の受信精度を高めることができる。   As a modification of the third or fourth embodiment, as in the second embodiment, the terminal control unit 23 of the terminal device 2 has a signal intensity control function for controlling the intensity of the infrared signal transmitted from the infrared transmission unit 21. You may have. According to such a configuration, it is possible to improve the reception accuracy of the light receiving sensor 30 while achieving the effects of the third or fourth embodiment.

なお、実施形態1〜4の変形例として、端末器2が、照度計測結果を送信する照度結果送信手段を、赤外線を送信する機能と別に備えてもよい。つまり、端末器2は、位置特定のために赤外線を送信し、これとは別に、例えば電波などを用いて照度計測結果を送信するものであってもよい。   As a modification of the first to fourth embodiments, the terminal device 2 may include an illuminance result transmitting unit that transmits the illuminance measurement result separately from the function of transmitting infrared rays. That is, the terminal device 2 may transmit infrared rays for specifying the position, and separately transmit the illuminance measurement result using radio waves, for example.

(実施形態5)
実施形態5の照明制御システムは、図6に示すように照明制御装置4aに、指向性を有する赤外線を放射する赤外線放射部45を備え、端末器2が赤外線放射部45からの赤外線を反射することによって赤外線信号を送信する点で、実施形態1と相違している。なお、実施形態1と同様の構成要素については、同一の符号を付して説明を省略する。
(Embodiment 5)
As shown in FIG. 6, the illumination control system according to the fifth embodiment includes an infrared radiation unit 45 that radiates directional infrared rays in the illumination control device 4 a, and the terminal device 2 reflects infrared rays from the infrared radiation unit 45. This is different from the first embodiment in that an infrared signal is transmitted. In addition, about the component similar to Embodiment 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.

照明制御装置4aの赤外線放射部45は、室内の全範囲を走査するように放射角度を変動させながら赤外線を放射する。また、位置特定部42は、受信信号に含まれている受信装置3の位置情報と赤外線放射部45の放射角度を用いて端末器2の位置を特定する。   The infrared radiation unit 45 of the illumination control device 4a emits infrared light while changing the radiation angle so as to scan the entire range in the room. In addition, the position specifying unit 42 specifies the position of the terminal device 2 using the position information of the receiving device 3 included in the received signal and the radiation angle of the infrared radiation unit 45.

一方、本実施形態において、端末器2の赤外線送信部21は自ら赤外線を発光するのではなく、照明制御装置4aの赤外線放射部45から放射された赤外線を反射することによって赤外線信号を送信する。また、本実施形態では、照度センサ20で計測された照度計測結果及び目標照度値の情報は、端末器制御部23の制御によって伝送部22から照明制御装置4aに送信される。   On the other hand, in the present embodiment, the infrared transmitter 21 of the terminal device 2 does not emit infrared light by itself, but transmits an infrared signal by reflecting the infrared radiation emitted from the infrared radiation section 45 of the illumination control device 4a. Moreover, in this embodiment, the illuminance measurement result measured by the illuminance sensor 20 and the information on the target illuminance value are transmitted from the transmission unit 22 to the illumination control device 4a under the control of the terminal device control unit 23.

以上、本実施形態によれば、端末器2が赤外線放射手段を備える必要がないので、端末器2の小型化及び軽量化を図ることができる。   As mentioned above, according to this embodiment, since the terminal device 2 does not need to be provided with an infrared radiation means, the terminal device 2 can be reduced in size and weight.

なお、実施形態5の変形例として、赤外線放射部45を照明制御装置4aと一体に備えるのではなく、照明制御装置4aとは別に備えてもよい。このような構成であっても、実施形態5と同様に端末器2の小型化及び軽量化を図ることができる。   As a modification of the fifth embodiment, the infrared radiation unit 45 may not be provided integrally with the illumination control device 4a, but may be provided separately from the illumination control device 4a. Even with this configuration, the terminal device 2 can be reduced in size and weight as in the fifth embodiment.

また、実施形態1〜5の変形例として、端末器2から送信される光が赤外線信号ではなく、例えば可視光などの他の波長領域の光であってもよい。例えば可視光の場合、例えば半導体レーザなどの発光手段が設けられる。このような構成であっても、実施形態1〜5と同様の効果を奏する。   As a modification of the first to fifth embodiments, the light transmitted from the terminal device 2 may be light in another wavelength region such as visible light instead of an infrared signal. For example, in the case of visible light, light emitting means such as a semiconductor laser is provided. Even if it is such a structure, there exists an effect similar to Embodiment 1-5.
