Description

本発明は、例えばオフィスのフロアに設置された複数台の照明の調光率を設定する照明調光率決定装置に関する。   The present invention relates to an illumination dimming rate determination device that sets dimming rates of a plurality of lights installed on, for example, an office floor.

オフィスのエネルギ消費増大に対する抑制は社会的な課題であり、このような背景の下、在席者付近だけ照明を点灯させることで消費電力量削減を図る照明制御方式が開発されている。すなわち、明るさが必要な箇所には必要な照度を与え、明るさが必要でない箇所は極力明るさを落とすことにより、消費電力の削減を図ることを目的としたものである。例えば、特許文献１に示す照明制御方式では、在席者の位置を人感センサで検知し、在席者の近傍は高い調光率として在席者から離れるにつれて徐々に調光率を下げていくことで、必要な明るさを維持しつつ消費電力量を抑えるようにしている。   Controlling the increase in energy consumption in the office is a social issue, and under such a background, an illumination control system has been developed that reduces power consumption by lighting only the vicinity of the occupant. That is, it is intended to reduce power consumption by giving necessary illuminance to a place where brightness is necessary and reducing brightness as much as possible in a place where brightness is not needed. For example, in the illumination control method shown in Patent Document 1, the position of the occupant is detected by a human sensor, and the dimming rate is gradually decreased as the occupant is away from the occupant as a high dimming rate in the vicinity of the occupant. By doing so, the power consumption is reduced while maintaining the necessary brightness.

特開平７−３１２２９４号公報JP 7-312294 A

しかしながら、オフィスの在席状態が時々刻々と変化する状況を考慮した場合、上記特許文献１で示されているような従来の制御方法で得られる調光率の設定は、明るさ維持と消費電力量削減の両立の観点で最良とはいえないものであった。例えば、図６は従来方式を適用した場合の、オフィスに１人在席している場合と２人在席している場合の調光率を概念的に示したものである。もし１人在席時の調光率で明るさ維持と消費電力量削減の両立を最適な状態で実現できているとすれば、２人在席時に前から在席していた在席者の隣の照明の調光率が増加するため、前から在席していた在席者にとっては明るすぎる状態となってしまう。つまり、１人在席時と２人在席時では最適な調光率の組合せは本来異なるが、従来方法を用いた場合は、このように在席状態の違いを考慮して調光率の組合せを変えることができなかった。また、従来方法では、在席者付近を７５０［ｌｘ］、在席者から少し離れたエリアを７５０［ｌｘ］〜２８０［ｌｘ］とするように調光出力値を設定できると記載されているが、その照度を満たすための調光出力値の決定方法については具体的な方法が開示されていなかった。   However, when considering the situation where the office attendance changes from moment to moment, the dimming rate setting obtained by the conventional control method as shown in Patent Document 1 described above is to maintain brightness and consume power. This was not the best in terms of both reductions in quantity. For example, FIG. 6 conceptually shows the dimming rate when one person is present in the office and when two persons are present when the conventional method is applied. If it is possible to achieve both brightness maintenance and power consumption reduction in an optimal state with the dimming rate when one person is present, the number of people who have been present before when two persons are present Since the dimming rate of the adjacent lighting increases, it becomes too bright for the occupant who was present from before. In other words, the optimal combination of dimming rates is different between when one person is present and when two people are present. However, when the conventional method is used, the dimming rate is adjusted in consideration of the difference in the presence state. The combination could not be changed. In the conventional method, it is described that the dimming output value can be set so that the vicinity of the occupant is 750 [lx] and the area slightly away from the occupant is 750 [lx] to 280 [lx]. However, no specific method has been disclosed for determining the dimming output value for satisfying the illuminance.

この発明は上記のような課題を解決するためになされたもので、在席状態が変化する中で在席者付近の明るさ維持と消費電力量削減を両立するよう、複数照明の調光率を設定することのできる照明調光率決定装置を得ることを目的とする。   The present invention has been made to solve the above-described problems, and the dimming rate of a plurality of illuminations is used so as to achieve both maintenance of brightness near the occupant and reduction of power consumption while the occupancy state changes. An object of the present invention is to obtain an illumination dimming rate determination device capable of setting

この発明に係る照明調光率決定装置は、複数台の照明の調光率を決定する照明調光率決定装置において、複数台の照明の設置位置を管理する照明情報管理部と、複数台の照明の設置数と同数の地点の目標照度を入力する目標照度入力部と、各照明の調光率を各々異なる変数として定義し、この変数を用いて各照明が目標照度入力部で定義された各地点に与える照度を逐点法で定式化することで、各照明の調光率を入力したときに各地点の照度を出力する連立方程式を生成する調光率・照度モデル生成部と、調光率・照度モデル生成部が生成した連立方程式を行列で表現し、各地点の照度を入力したときに各照明の調光率を出力する逆行列を生成する照度・調光率モデル生成部と、照度・調光率モデル生成部が生成した逆行列に対して、目標照度入力部から入力された各地点の照度を入力として調光率を出力として得る調光率決定部とを備え、照度・調光率モデル生成部は、逆行列を生成する前に、各地点数分の連立方程式を行列で表現したときにこの行列が正則か否かを判定し、正則でない場合に目標照度入力部に別の地点を選択するように通知し、目標照度入力部が再選択した別の地点の情報を用いて再度処理を行うものである。 An illumination dimming rate determination device according to the present invention is an illumination dimming rate determination device that determines a dimming rate of a plurality of lights, and an illumination information management unit that manages the installation positions of the plurality of lights, The target illuminance input unit that inputs the target illuminance at the same number of points as the number of installed lights and the dimming rate of each light are defined as different variables, and each variable is defined in the target illuminance input unit using this variable. By formulating the illuminance given to each point by the point-by-point method, a dimming rate / illuminance model generation unit that generates simultaneous equations that output the illuminance at each point when the dimming rate of each illumination is input, Illuminance / dimming rate model generation unit that generates simultaneous matrix equations generated by the light rate / illuminance model generation unit in a matrix and generates an inverse matrix that outputs the dimming rate of each illumination when the illuminance at each point is input; The target illumination is applied to the inverse matrix generated by the illuminance / dimming rate model generation unit. And an obtaining dimming ratio determining unit as an output a dimming ratio as an input illuminance of each point that is input from the input unit, the illumination-light control rate model generating unit, before generating the inverse matrix, local points min When this simultaneous equation is expressed in a matrix, it is determined whether or not this matrix is regular, and if it is not regular, the target illuminance input unit is notified to select another point, and the target illuminance input unit re-selects The processing is performed again using the information on the point .

この発明の照明調光率決定装置は、各照明の調光率を入力した時に各地点の照度を出力する連立方程式を生成し、この連立方程式を行列で表現して、各地点の照度を入力した時に各照明の調光率を出力する逆行列を生成し、かつ、この逆行列に対して、各地点の照度を入力として調光率を出力として得るようにしたので、在席状態が変化する中で在席者付近の明るさ維持と消費電力量削減を両立するよう、複数照明の調光率を設定することができる。   The illumination dimming rate determination device of the present invention generates simultaneous equations that output the illuminance at each point when the dimming rate of each illumination is input, expresses the simultaneous equation as a matrix, and inputs the illuminance at each point. When this happens, an inverse matrix that outputs the dimming rate of each illumination is generated, and the illuminance at each point is input to the inverse matrix to obtain the dimming rate as an output. In the meantime, the dimming rate of the plurality of illuminations can be set so as to achieve both the brightness maintenance near the occupant and the power consumption reduction.

図１に示す照明調光率決定装置は、目標照度入力部１、照明情報管理部２、調光率・照度モデル生成部３、照度・調光率モデル生成部４および調光率決定部５を備えている。
目標照度入力部１は、ユーザや他システムに対して、オフィスフロア内の複数地点の目標照度を入力するための機能を提供する。図２は目標照度入力部１における入力画面の一例を示しており、図２（ａ）は、オフィスフロア図を表示することで複数地点を選択して目標照度を入力できるようにしたものである。また、図２（ｂ）に示す例では、各照明の直下の照度を入力させるようなインタフェースとしたものである。ただし、目標照度入力部１で入力する目標照度の数は照明の数と同数とする。 Embodiment 1 FIG.
1 is a block diagram showing an illumination dimming rate determining apparatus according to Embodiment 1 of the present invention.
The illumination dimming rate determination device shown in FIG. 1 includes a target illuminance input unit 1, an illumination information management unit 2, a dimming rate / illuminance model generation unit 3, an illuminance / dimming rate model generation unit 4, and a dimming rate determination unit 5 It has.
The target illuminance input unit 1 provides a function for inputting target illuminances at a plurality of points in the office floor to a user or another system. FIG. 2 shows an example of an input screen in the target illuminance input unit 1, and FIG. 2 (a) displays the office floor diagram so that a plurality of points can be selected and the target illuminance can be input. . Further, in the example shown in FIG. 2B, an interface is provided for inputting the illuminance immediately below each illumination. However, the number of target illuminances input by the target illuminance input unit 1 is the same as the number of illuminations.

照明情報管理部２は、オフィスフロア内における照明の設置位置情報、および設置された照明の配光曲線情報を管理している。
設置位置情報を参照することで、オフィスフロア内に設置された照明と照明の位置関係、オフィスフロアの各地点と照明の位置関係を算出することが可能である。
配光曲線情報を参照することで、オフィスフロア内に設置された照明器具がオフィスフロアの各地点へ与える光度情報を得ることが可能である。 The illumination information management unit 2 manages the installation position information of the illumination in the office floor and the light distribution curve information of the installed illumination.
By referring to the installation position information, it is possible to calculate the positional relationship between the lighting installed in the office floor and the lighting, and the positional relationship between each point on the office floor and the lighting.
By referring to the light distribution curve information, it is possible to obtain the light intensity information given to each point on the office floor by the lighting equipment installed in the office floor.

調光率・照度モデル生成部３は、オフィスフロア内に設置された各照明が目標照度入力部１で設定された各地点へ与える照度の影響を逐点法により定式化する。以下に、本手順を詳細に説明する。   The dimming rate / illuminance model generation unit 3 formulates the influence of the illuminance exerted on each point set by the target illuminance input unit 1 by each illumination installed in the office floor by a point-by-point method. This procedure will be described in detail below.

先ず、図３を用いて目標照度入力部１で設定された各地点の内の１点（以下、地点k）とオフィスフロア内に設置された全照明の内の１台（以下、照明i）との関係を説明する。地点kにおける照度e（単位：lx／ルックス）は、照明iのθ方向の光度I(θ)、照明iの調光率r、角度θ、地点kと照明iの距離dを用いて、式（１）で表現できる。

Figure 0005631234
ここでcos(θ)=h/dであるため、式（１）は式（２）で表現できる。
Figure 0005631234
なお、光度I(θ)は、照明情報管理部２が保持する配光曲線情報を利用する。 First, one of the points set in the target illuminance input unit 1 with reference to FIG. 3 (hereinafter referred to as point k) and one of all the lights installed on the office floor (hereinafter referred to as lighting i). Will be described. The illuminance e (unit: lx / lux) at the point k is expressed by using the luminous intensity I (θ) of the illumination i in the θ direction, the dimming rate r of the illumination i, the angle θ, and the distance d between the point k and the illumination i. It can be expressed by (1).
Figure 0005631234
Here, since cos (θ) = h / d, Expression (1) can be expressed by Expression (2).
Figure 0005631234
The light intensity I (θ) uses light distribution curve information held by the illumination information management unit 2.

次に、オフィスフロア内にN台(1,2, ・・・,i,・・・N)の照明が設置されている場合を考えると、地点kの照度はN台の照明の影響を受ける。すなわち、各照明ｉと地点kとの角度をθi、各照明が地点kの方向へ与える光度をI(θi)、および各照明の調光率をriとすると、地点kにおける照度ekは、式（３）で表現できる。ただし、ここではオフィスフロア内における高さh（机上面と天井面との垂直距離）は一定とする。

Figure 0005631234
Next, considering the case where N (1,2, ..., i, ... N) lights are installed in the office floor, the illuminance at point k is affected by the N lights. . That is, if the angle between each illumination i and point k is θi, the luminous intensity given to each point in the direction of point k is I (θi), and the dimming rate of each illumination is r i , the illuminance e k at point k is , Can be expressed by equation (3). However, here, the height h in the office floor (the vertical distance between the desk surface and the ceiling surface) is constant.
Figure 0005631234

さらに、式（３）を用いて目標照度入力部１で設定された全ての地点(1,2, ・・・,k,・・・N)の照度を求めるように行列式で表すと式（４）の通りとなる。

Figure 0005631234
ここで、x_k、y_kはオフィスフロア内における地点kの位置、x_i、y_iはオフィスフロア内における照明iの位置である。
以上が調光率・照度モデル生成部３の動作である。 Furthermore, when the illuminance at all the points (1, 2,..., K,... N) set in the target illuminance input unit 1 is obtained using the equation (3), the equation ( 4) As follows.
Figure 0005631234
Here, x_k and y_k are the position of the point k in the office floor, and x_i and y_i are the positions of the illumination i in the office floor.
The operation of the dimming rate / illuminance model generation unit 3 has been described above.

再び図１に戻り、照度・調光率モデル生成部４について説明する。

Figure 0005631234
Returning to FIG. 1 again, the illuminance / light control rate model generation unit 4 will be described.
Figure 0005631234

Figure 0005631234
そのため、照度・調光率モデル生成部４で逆行列を算出する前にその行列式を求めて逆行列を算出可能であるか否かを事前に評価し、逆行列を算出する条件を満たさない場合は目標照度入力部１に通知し、再度位置を変えて目標照度を入力させるよう構成してもよい。
Figure 0005631234
Therefore, before calculating the inverse matrix in the illuminance / dimming ratio model generation unit 4, the determinant is obtained to evaluate in advance whether the inverse matrix can be calculated, and the condition for calculating the inverse matrix is not satisfied. In this case, the target illuminance input unit 1 may be notified and the position may be changed again to input the target illuminance.

最後に、調光率決定部５について説明する。

Figure 0005631234
Finally, the dimming rate determination unit 5 will be described.
Figure 0005631234

尚、照明の調光率は０％から１００％の範囲で設定可能であるが、本調光率決定部５は０％から１００％の範囲以外の値を出力する場合がある。例えば、ある照明の直下照度を１０００［ｌｘ］としてその隣の照明の直下照度を０［ｌｘ］にするといった極端な設定を行った場合、一方の照明を１００％以上、他方の照明を０％以下の値に設定するような値を出力する場合がある。
ユーザや他システムは、調光率決定部５が出力する調光率の値を参照し、０％から１００％以外の値となっていた場合はその近傍の目標照度を徐々に修正することで、望ましい照明の調光率を得ることができる。 The dimming rate of illumination can be set in the range of 0% to 100%, but the dimming rate determining unit 5 may output a value outside the range of 0% to 100%. For example, when an extreme setting is made such that the illuminance directly below one illumination is 1000 [lx] and the illuminance directly below that is 0 [lx], one illumination is 100% or more and the other illumination is 0%. A value that is set to the following value may be output.
The user or other system refers to the value of the dimming rate output from the dimming rate determining unit 5, and when it is a value other than 0% to 100%, it gradually corrects the target illuminance in the vicinity thereof. The desired dimming rate of illumination can be obtained.

このように、実施の形態１の照明調光率決定装置では、オフィスフロアの任意の箇所の照度を指定することで、その照度を満たす照明の調光率の組合せを取得することが可能である。そのため、１人在席時はその在席者近傍の照度を満たす調光率を、また、２人在席していた場合は２人の近傍の照度を同時に満たす調光率を、といったように在席者の変化に合わせてその在席者近傍の照度を満たす調光率の設定を取得することができる。   As described above, in the lighting dimming rate determination device according to the first embodiment, by specifying the illuminance at an arbitrary location on the office floor, it is possible to acquire a combination of lighting dimming rates that satisfy the illuminance. . Therefore, when one person is present, the dimming rate that satisfies the illuminance near the occupant, and when two people are present, the dimming rate that simultaneously satisfies the illuminance near the two people, etc. The setting of the light control rate that satisfies the illuminance near the occupant can be acquired in accordance with the change of the occupant.

以上説明したように、実施の形態１の照明調光率決定装置によれば、複数台の照明の調光率を決定する照明調光率決定装置において、複数台の照明の設置位置を管理する照明情報管理部と、複数台の照明の設置数と同数の地点の目標照度を入力する目標照度入力部と、各照明の調光率を各々異なる変数として定義し、この変数を用いて各照明が目標照度入力部で定義された各地点に与える照度を逐点法で定式化することで、各照明の調光率を入力した時に各地点の照度を出力する連立方程式を生成する調光率・照度モデル生成部と、調光率・照度モデル生成部が生成した連立方程式を行列で表現し、各地点の照度を入力した時に各照明の調光率を出力する逆行列を生成する照度・調光率モデル生成部と、照度・調光率モデル生成部が生成した逆行列に対して、目標照度入力部から入力された各地点の照度を入力として調光率を出力として得る調光率決定部とを備えたので、在席状態が変化する中で在席者付近の明るさ維持と消費電力量削減を両立するよう、複数照明の調光率を設定することができる。   As described above, according to the illumination dimming rate determination device of the first embodiment, in the illumination dimming rate determination device that determines the dimming rate of a plurality of lights, the installation positions of the plurality of lights are managed. The lighting information management unit, the target illuminance input unit that inputs the target illuminance at the same number of points as the number of installed multiple lighting units, and the dimming rate of each lighting are defined as different variables. Dimming rate to generate simultaneous equations that output the illuminance at each point when the dimming rate of each illumination is input by formulating the illuminance given to each point defined by the target illuminance input unit by the point method Illuminance to generate an inverse matrix that outputs the dimming rate of each illumination when the illuminance model generation unit and the simultaneous equations generated by the dimming rate / illuminance model generation unit are expressed as a matrix and the illuminance at each point is input The dimming rate model generation unit and the illuminance / dimming rate model generation unit Because it has a dimming rate determination unit that obtains the dimming rate as an output by inputting the illuminance at each point input from the target illuminance input unit for the matrix, the vicinity of the occupant in the presence state changes The dimming rate of the plurality of illuminations can be set so as to achieve both brightness maintenance and power consumption reduction.

また、実施の形態１の照明調光率決定装置によれば、照度・調光率モデル生成部は、逆行列を生成する前に、各地点数分の連立方程式を行列で表現した時にこの行列が正則か否かを判定し、正則でない場合に目標照度入力部に別の地点を選択するように通知し、目標照度入力部が再選択した別の地点の情報を用いて再度処理を行うようにしたので、確実に複数照明の調光率を設定することができる。   Further, according to the illumination dimming rate determination device of the first embodiment, the illuminance / dimming rate model generation unit generates the matrix when the simultaneous equations for the number of points are expressed as a matrix before generating the inverse matrix. It is determined whether or not it is regular, and if it is not regular, the target illuminance input unit is notified to select another point, and the target illuminance input unit performs processing again using information on another point reselected. As a result, the dimming rate of the plurality of illuminations can be set with certainty.

実施の形態２．
図４は、実施の形態２の照明調光率決定装置を示す構成図である。
実施の形態２における照明調光率決定装置は、目標照度入力部１、照明情報管理部２、調光率・照度モデル生成部３、照度・調光率モデル生成部４、調光率決定部５ａおよびダミー地点選択部６を備えている。 Embodiment 2. FIG.
FIG. 4 is a configuration diagram illustrating an illumination dimming rate determining apparatus according to the second embodiment.
The illumination dimming rate determination device according to the second embodiment includes a target illuminance input unit 1, an illumination information management unit 2, a dimming rate / illuminance model generation unit 3, an illuminance / dimming rate model generation unit 4, and a dimming rate determination unit. 5a and a dummy point selection unit 6 are provided.

目標照度入力部１は、実施の形態１の目標照度入力部１と同様の機能を有するものである。但し、実施の形態１では、目標照度入力部１で入力可能な地点の数は照明の数と同数としたが、実施の形態２では、地点の数は照明の数以下であれば構わない。   The target illuminance input unit 1 has the same function as the target illuminance input unit 1 of the first embodiment. However, in the first embodiment, the number of points that can be input by the target illuminance input unit 1 is the same as the number of lights. However, in the second embodiment, the number of spots may be equal to or less than the number of lights.

ダミー地点選択部６は、目標照度入力部１で入力された地点の数が照明の数と同数になるように、ダミーの地点を選択する機能を有している。図５は、ダミー地点選択部６による地点の選択方法の一例を示しているが、本例では目標照度入力部１で入力された各地点を最も近い照明に割り付け、余った照明の直下をダミーの地点として選択している。   The dummy spot selection unit 6 has a function of selecting a dummy spot so that the number of spots input by the target illuminance input unit 1 is the same as the number of lights. FIG. 5 shows an example of a method for selecting a spot by the dummy spot selection unit 6. In this example, each spot input by the target illuminance input unit 1 is assigned to the nearest illumination, and a dummy directly below the remaining illumination is assigned. Is selected as the point.

照明情報管理部２、調光率・照度モデル生成部３および照度・調光率モデル生成部４の構成は実施の形態１と同様であるため、その説明は省略する。   Since the configuration of the illumination information management unit 2, the dimming rate / illuminance model generation unit 3, and the illuminance / dimming rate model generation unit 4 is the same as that of the first embodiment, description thereof is omitted.

Figure 0005631234
そのため、照度・調光率モデル生成部４で逆行列を算出する前にその行列式を求めて逆行列を算出可能であるか否かを事前に評価し、逆行列を算出する条件を満たさない場合はダミー地点選択部６に通知し、再度位置を変えるよう構成してもよい。
Figure 0005631234
Therefore, before calculating the inverse matrix in the illuminance / dimming ratio model generation unit 4, the determinant is obtained to evaluate in advance whether the inverse matrix can be calculated, and the condition for calculating the inverse matrix is not satisfied. In such a case, the dummy point selection unit 6 may be notified and the position may be changed again.

最後に、調光率決定部５ａについて説明する。本処理部は、第１ステップ実行部５１、第２ステップ実行部５２および第３ステップ実行部５３の３ステップで処理を行う。以下、各ステップ実行部の処理を説明する。
