Description

本発明は街路灯等照明器具の点消灯や調光を制御する照明制御システムに関する。   The present invention relates to an illumination control system that controls lighting and dimming of lighting fixtures such as street lamps.

従来、車道や歩道等の道路を照明する街路灯の照明制御システムの一例としては、夜間に街路灯を全光束（１００％）で点灯した後、所定時間（例えば４時間）が経過した時点で減光する調光制御または消灯に切り替えることにより、人通りや交通量の少ない深夜における電力消費量を低減するものが知られている（例えば、特許文献１参照。以下、従来技術１という）。   Conventionally, as an example of a lighting control system for a street light that illuminates a road such as a roadway or a sidewalk, a predetermined time (for example, 4 hours) elapses after the street light is turned on at full luminous flux (100%) at night. It is known to reduce power consumption in the middle of the night when traffic light and traffic volume are low by switching to dimming control or dimming (for example, refer to Patent Document 1, hereinafter referred to as Prior Art 1).

また、これら街路灯のランプ寿命による玉切れについては、その管理者が定期的に巡回して目視で確認することにより検知していた。しかし、この方法では、管理者が街路灯の玉切れの目視チェックのために定期的に巡回しなければならず、ランニングコストの増大を招く。   Further, the outage due to the lamp life of these street lamps was detected by the manager periodically visiting and checking visually. However, in this method, the manager has to go around periodically to visually check the street lamps for running out of light, resulting in an increase in running cost.

そこで、他の従来例では、照明器具と別置の照度センサにより、ランプが点灯中の室内の照度を検出し、この照度検出値が所定値を超えているときに、そのランプの玉切れの監視データを送信する遠隔照明制御システムが知られている（例えば、特許文献２参照。以下、従来技術２という）。   Therefore, in another conventional example, the illuminance sensor installed separately from the luminaire detects the illuminance in the room where the lamp is lit, and when this illuminance detection value exceeds a predetermined value, A remote lighting control system that transmits monitoring data is known (see, for example, Patent Document 2, hereinafter referred to as Conventional Technology 2).

また、ランプの平均寿命を考慮して予め決められた期間毎に、ランプの全数を交換する方法（例えば、特許文献３参照。以下、従来技術３という）が知られている。
特開２００３−３４７０６７号公報 特開２００５−６３８０４号公報 特開２００１−２１０４８１号公報 In addition, a method is known in which the total number of lamps is replaced every predetermined period in consideration of the average life of the lamps (see, for example, Patent Document 3, hereinafter referred to as Prior Art 3).
Japanese Patent Laid-Open No. 2003-347067 Japanese Patent Laid-Open No. 2005-63804 JP 2001-210481 A

しかしながら、上記従来技術１では、街路灯の設置場所によっては、夜間の所定時間経過後の深夜に人通りや交通量が減少しない場合もあり、この場合は街路の照度が低くなり過ぎ、暗過ぎるために交通安全性が低下するという新たな課題が発生する。   However, in the above prior art 1, depending on the place where the street light is installed, the traffic and traffic volume may not decrease at midnight after a predetermined time at night. In this case, the street illumination is too low and too dark. Therefore, the new subject that traffic safety falls will generate | occur | produce.

また、これとは逆に、街路灯の周囲にある店舗等の人工照明により所要の明るさが確保されている場合には、所定時間の経過前に減光制御して節電することが可能であるにも拘らず、所定時間が経過する前には減光しないので、節電効果のさらなる向上を図ることができない。   On the other hand, if the required brightness is secured by artificial lighting such as stores around street lamps, it is possible to save power by dimming control before the lapse of a predetermined time. Nevertheless, since the light is not dimmed before the predetermined time elapses, the power saving effect cannot be further improved.

そこで、これらの課題を解決するために、複数の街路灯に照度センサや交通量検出センサをそれぞれ設け、これらセンサの各検出値に応じて各街路灯をそれぞれ個別に点消灯や調光等の光出力制御を行う方法が考えられる。   Therefore, in order to solve these problems, a plurality of street lights are provided with illuminance sensors and traffic volume detection sensors, and each street light is individually turned on / off, dimmed, etc. according to each detected value of these sensors. A method of performing light output control is conceivable.

しかし、この制御方法では、その光出力制御が各街路灯間で何らの関連もなく、バラバラに行なうことになり、調光度が街路灯毎に相違するので、道路上の明るい部分と暗い部分の差が明瞭になり、この明暗差が街路灯に沿って繰り返されるので、視感環境が悪化し、不快感が増すという新たな課題が発生する。   However, in this control method, the light output control is performed separately without any relation between the street lamps, and the dimming degree is different for each street lamp. Since the difference becomes clear and the difference in brightness is repeated along the street light, a new problem arises that the visual environment deteriorates and uncomfortable feeling increases.

本発明はこれらの事情を考慮してなされたもので、その目的は、周囲の状況に応じて複数の照明器具をこれらの間で調和のとれた調光を行なう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 consideration of these circumstances, and an object thereof is to provide a lighting control system that performs dimming light control between a plurality of lighting fixtures according to the surrounding situation. is there.

そして、上記従来技術２では、照度センサの検出値が外光等の影響により必ずしも正確ではなく、精度が高くないという課題がある。   And in the said prior art 2, there exists a subject that the detection value of an illumination intensity sensor is not necessarily accurate by the influence of external light etc., and accuracy is not high.

また、上記従来技術３では、ランプ寿命が実際の点灯時間や点滅回数により変動するので、寿命末期でないランプまで、全数交換してしまうために、コストが増大するという課題がある。   Moreover, in the said prior art 3, since a lamp life changes with the actual lighting time and the frequency | count of blinking, since all lamps which are not the end of life are replaced | exchanged, there exists a subject that cost increases.

本発明はこれらの事情を考慮してなされたもので、その目的は、ランプ切れによるランプ交換に伴うコストの低減を図ることができる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 these circumstances, and an object of the present invention is to provide an illumination control system capable of reducing the cost associated with lamp replacement due to lamp burnout.

このために、複数の照明器具毎に調光度が相違しないので、照明器具毎に調光度が相違することによる視感環境の悪化を未然に防止することができる。   For this reason, since the dimming degree is not different for each of the plurality of lighting fixtures, it is possible to prevent deterioration of the visual environment due to the dimming degree being different for each lighting fixture.

また、照度センサは、第１の照明器具のみに設け、第２の照明器具には設けなくてもよいので、その分、コスト低減を図ることができる。   Further, since the illuminance sensor is provided only in the first lighting fixture and not in the second lighting fixture, the cost can be reduced accordingly.

請求項２に係る照明制御システムによれば、照度センサの照度検出値のみならず、交通量検出センサの交通量検出値の両者により光出力制御値を求め、この光出力制御値により第１，第２の照明器具の光出力を制御するので、照明器具の周囲の照度と道路の交通量の両者に共に応じた好適な調光度により道路を照明することができる。   According to the illumination control system according to claim 2, the light output control value is obtained not only by the illuminance detection value of the illuminance sensor but also by the traffic volume detection value of the traffic volume detection sensor.

図１は本発明の第１の実施形態に係る照明制御システム１の要部正面図である。照明制御システム１は、車道や歩道等の道路の幅方向両端部または一端部において、長手方向に沿って複数の街路灯２，２，…を所要のピッチで配設している。   FIG. 1 is a front view of an essential part of a lighting control system 1 according to a first embodiment of the present invention. In the lighting control system 1, a plurality of street lamps 2, 2,...

これら街路灯２，２，…は、複数のグループＡ，Ｂ，…に区分されている。これらの各グループＡ，Ｂ，…は、少なくとも１台の第１の照明装置である第１街路灯２Ａ，２Ｂ，…と、複数台の第２の照明装置である第２街路灯２ｐ，２ｐ，…とをそれぞれ具備している。   These street lamps 2, 2,... Are divided into a plurality of groups A, B,. Each of these groups A, B,... Includes at least one first lighting device 2A, 2B,... And a plurality of second lighting devices 2nd street light 2p, 2p. ,... Respectively.

第１照明器具２Ａ２，２Ｂ２，…はＨＩＤランプ（HIGH INTENSITY DISCHARGE LAMPS）や蛍光ランプ等のランプ（光源）を具備しており、これらの点消灯や調光は第１調光器２Ａ５，２Ｂ５，…によりそれぞれ制御される。   The first lighting fixtures 2A2, 2B2,... Are equipped with lamps (light sources) such as HID lamps (HIGH INTENSITY DISCHARGE LAMPS) and fluorescent lamps. Controlled by.

照度センサ２Ａ４，２Ｂ４，…は、第１照明器具２Ａ２，２Ｂ２，…により照明される被照明部の路面等の照度を検出する。   The illuminance sensors 2A4, 2B4,... Detect the illuminance on the road surface of the illuminated part illuminated by the first lighting fixtures 2A2, 2B2,.

第１調光器２Ａ５，２Ｂ５，…は、この照度センサ２Ａ４，２Ｂ４，…からの照度検出値に基づいて点消灯や調光度の光出力制御値を求める。すなわち、第１調光器２Ａ５，２Ｂ５は例えば照度検出値を所要の照度目標値と比較してその差を求め、さらに、この差を解消して照度検出値が照度目標値になるような調光度と点消灯を光出力制御値として求め、この光出力制御値になるように照明器具２Ａ２，２Ｂ２，…の点消灯や調光度を制御する機能を有する。   The first dimmers 2A5, 2B5,... Calculate the light output control values for turning on / off and the dimming degree based on the illuminance detection values from the illuminance sensors 2A4, 2B4,. That is, for example, the first dimmers 2A5 and 2B5 compare the detected illuminance value with a required illuminance target value to obtain the difference, and further adjust the illuminance detected value to become the illuminance target value by eliminating this difference. The light intensity and the turn-on / off are obtained as light output control values, and the light fixtures 2A2, 2B2,...

第１通信装置２Ａ３，２Ｂ３，…は、無線通信用のアンテナＡＮＴをそれぞれ有し、各自の第１調光器２Ａ５，２Ｂ５，…からの光出力制御値を中継可能に、同一グループＡ，Ｂの第２街路灯２ｐの通信装置にそれぞれ出力する機能を有する。   The first communication devices 2A3, 2B3,... Each have an antenna ANT for wireless communication, so that the optical output control values from the respective first dimmers 2A5, 2B5,. The second street lamp 2p has a function of outputting to each communication device.

一方、各第２街路灯２ｐは複数あり、上記照度センサ２Ａ４，２Ｂ４を具備していない点で上記第１街路灯２Ａ，２Ｂ，…とは主に相違するが、第１街路灯２Ａ，２Ｂ，…と同様にポール２ｐ１、ＨＩＤランプ等のランプを備えた第２照明器具２ｐ２、第２通信装置２ｐ３、第２調光器２ｐ５をそれぞれ備えている。   On the other hand, there are a plurality of second street lamps 2p, which are mainly different from the first street lamps 2A, 2B,... In that the illuminance sensors 2A4, 2B4 are not provided, but the first street lamps 2A, 2B. ,... Are provided with a pole 2p1, a second lighting fixture 2p2 provided with a lamp such as an HID lamp, a second communication device 2p3, and a second dimmer 2p5.

各第２通信装置２ｐ３は、同一グループＡ，Ｂ，…内の上記第１通信装置２Ａ３，２Ｂ３，…から直接、または他の第２通信装置２ｐ３の中継を介して第１調光器２Ａ５，２Ｂ５，…からの点消灯や調光度の光出力制御信号を受信して自己の第２調光器２ｐ４に与え、この第２調光器２ｐ４により第２照明器具２ｐ２を点消灯や調光を行なう機能を有する。ここで、第１街路灯２Ａ，２Ｂ，…、および第２街路灯２ｐはそれぞれ固有のアドレスおよび各グループアドレスが図示しない記憶部に記憶されており、互いを識別することができる。つまり、各通信装置は、固有のアドレスまたはグループアドレスを用いて互いに通信が行なわれる。   Each second communication device 2p3 is connected to the first dimmer 2A5 directly from the first communication devices 2A3, 2B3,...

Based on this detected illuminance value, a light output control value for turning on / off or dimming is obtained, and each of the first lighting fixtures 2A2, 2B2,... Is turned on or off so that the light output control value is obtained. .

そして、これら第１調光器２Ａ５，２Ｂ５，…により求めた光出力制御信号は各自の第１通信装置２Ａ３，２Ｂ３，…から各グループＡ，Ｂ，…内の第２街路灯２ｐ，２ｐ，…へそれぞれ無線送信される。   The light output control signals obtained by the first dimmers 2A5, 2B5,... Are sent from the first communication devices 2A3, 2B3,... To the second street lamps 2p, 2p,. ... are transmitted wirelessly.

各第２街路灯２ｐの第２通信装置２ｐ３は、自己のグループＡ，Ｂ，…の第１通信装置２Ａ３，２Ｂ３からの光出力制御信号のみを、直接、または他の同一グループＡ，Ｂ，…の第２通信装置２ｐ３の中継を介して受信し、自己の各第２調光器２ｐ４へそれぞれ与える。   The second communication device 2p3 of each second street light 2p receives only the light output control signal from the first communication device 2A3, 2B3 of its own group A, B,... Directly or other same group A, B, Are received via the relay of the second communication device 2p3 and given to each of the second dimmers 2p4.

これにより、各第２調光器２ｐ４は、同一グループＡ，Ｂ，…内の各第１調光器２Ａ５，２Ｂ５，…により求めた光出力制御値により各第２照明器具２ｐ２を制御する。   Thereby, each 2nd light control device 2p4 controls each 2nd lighting fixture 2p2 by the light output control value calculated | required by each 1st light control device 2A5, 2B5, ... in the same group A, B, ....

したがって、Ａグループの各第２照明器具２ｐ２は、同じＡグループに属する第１照明器具２Ａ２と同一の光出力値（点消灯または調光度）に制御される。これと同様に、Ｂグループ以下の各第２照明器具２ｐ２についても、同一グループＢ，…にそれぞれ属する第１照明器具２Ｂ２，…と同一の光出力制御値に制御される。   Therefore, each 2nd lighting fixture 2p2 of A group is controlled by the same light output value (lighting-off or dimming degree) as 1st lighting fixture 2A2 which belongs to the same A group. Similarly, the second lighting fixtures 2p2 below the B group are controlled to the same light output control values as the first lighting fixtures 2B2,... Belonging to the same group B,.

このために、各照明器具２Ａ２，２Ｂ２，…、２ｐの調光度は各グループＡ，Ｂ，…毎に同一であるので、同一の調光度が所定区間続く。   For this reason, since the dimming degree of each lighting fixture 2A2, 2B2, ..., 2p is the same for every group A, B, ..., the same dimming degree continues for a predetermined area.

これにより、従来例のように各照明器具２Ａ２，２Ｂ２，…、２ｐ毎に調光が変化するために、明るい区域と暗い区域が明瞭に区別され、これら明暗区域が道路の長手方向に沿って繰り返す場合の視感環境の悪化を未然に防止することができる。   Thereby, since dimming changes for each lighting fixture 2A2, 2B2,..., 2p as in the conventional example, the bright and dark areas are clearly distinguished, and these bright and dark areas are along the longitudinal direction of the road. It is possible to prevent deterioration of the visual environment when repeated.

また、この照明制御システム１によれば、各グループ２Ａ，２Ｂ，…の照度センサ２Ａ２，２Ｂ２，…の照度検出値に基づいて各照明器具２Ａ２，２Ｂ２，…、２ｐ２の光出力を制御するので、常に周囲の照度に応じた光出力制御を行なうことができる。   Moreover, according to this illumination control system 1, since the light output of each lighting fixture 2A2, 2B2, ..., 2p2 is controlled based on the illumination intensity detection value of illumination sensor 2A2, 2B2, ... of each group 2A, 2B, ... Therefore, it is possible to always perform light output control according to ambient illuminance.

さらに、照度センサ２Ａ４，２Ｂ４，…は各グループ２Ａ，２Ｂ，…毎に少なくとも１台ずつ設ければよく、各街路灯２毎にそれぞれ設ける必要が無いので、照度センサ２Ａ４，２Ｂ４，…の個数を減らしてコスト低減を図ることができる。   Further, at least one illuminance sensor 2A4, 2B4,... Suffices to be provided for each group 2A, 2B,... And it is not necessary to provide each illuminance sensor 2A, 2B4,. This can reduce the cost.

図２は本発明の第２実施形態に係る照明制御システム１Ａの要部平面図である。この照明制御システム１Ａは、複数（図２では２台）の第１照明装置２Ａ，２Ｂ間において複数の第２照明装置２ｐ，２ｐ，…が列状に配設されている場合に、これら第２照明装置２ｐ，２ｐ，…の調光度を、これらの両側にある第１照明装置２Ａ，２Ｂの両調光度（例えば図２では５０％と７５％）の中間値であって、しかも、これら両側の第１照明装置２Ａ，２Ｂからの距離に比例して徐々に調光度が相違するように制御する点に特徴がある。   FIG. 2 is a plan view of an essential part of an illumination control system 1A according to the second embodiment of the present invention. This illumination control system 1A is used when a plurality of second illumination devices 2p, 2p,... Are arranged in a row between a plurality of (two in FIG. 2) first illumination devices 2A, 2B. The dimming levels of the two lighting devices 2p, 2p,... Are intermediate values of both dimming levels (for example, 50% and 75% in FIG. 2) of the first lighting devices 2A and 2B on both sides thereof. It is characterized in that the dimming degree is controlled to gradually differ in proportion to the distance from the first lighting devices 2A and 2B on both sides.

このために、例えば調光度が５０％のＡグループの第１照明装置２Ａから、同７５％のＢグループの第１照明装置２Ｂまで調光度が急激に変化せずにＡグループの第１照明装置２ＡからＢグループの第１照明装置２Ｂまで調光度が５％ずつ徐々に上昇して行くので、調光度の変化をなだらかにすることができる。このために、調光度が急激に変化することによる不快感や視感環境の低下を抑制することができる。   For this reason, for example, the dimming degree does not change rapidly from the first illuminating device 2A of the A group having a dimming degree of 50% to the first illuminating device 2B of the B group having 75% of the dimming degree. Since the dimming degree gradually increases by 5% from 2A to the first lighting device 2B of the B group, the change of the dimming degree can be made smooth. For this reason, it is possible to suppress discomfort and a decrease in visual environment due to a sudden change in the dimming degree.

なお、上記第１，第２実施形態に係る照明制御システム１，１Ａにおける照度センサ２Ａ４，２Ｂ４，…を、図示しない光学式や電波式等の交通量検出センサに置換してもよい。この場合は第１調光器２Ａ５，２Ｂ５，…を、この交通量検出センサにより検出された交通量検出値に基づいて所望の点消灯または調光度を求めるように構成する。   Note that the illuminance sensors 2A4, 2B4,... In the illumination control systems 1 and 1A according to the first and second embodiments may be replaced with optical or radio traffic detection sensors (not shown). In this case, the first dimmers 2A5, 2B5,... Are configured to obtain a desired lighting-off or dimming degree based on the traffic volume detection value detected by the traffic volume detection sensor.

この構成によれば、道路の交通量に応じた好適な調光度により道路を照明できるので、節電を図りつつ主に交通安全性を向上させることができる。例えば、単位時間に通過する車の量が多い場合には調光度を維持し、渋滞時には調光度を下げることができる。   According to this configuration, the road can be illuminated with a suitable dimming degree according to the traffic volume of the road, so that it is possible to mainly improve traffic safety while saving power. For example, the dimming degree can be maintained when the amount of vehicles passing through the unit time is large, and the dimming degree can be lowered during a traffic jam.

また、この交通量検出センサを上記照度センサ２Ａ４，２Ｂ４，…と共に設け、これら交通量検出センサにより検出された交通量検出値と、照度センサ２Ａ４，２Ｂ４，…により検出された照度検出値の両者に基づいて所望の点消灯または調光度等の光出力制御値を求めるように構成してもよい。   Further, this traffic volume detection sensor is provided together with the illuminance sensors 2A4, 2B4,..., Both of the traffic volume detection values detected by these traffic volume detection sensors and the illuminance detection values detected by the illuminance sensors 2A4, 2B4,. A light output control value such as a desired light extinction or dimming degree may be obtained based on the above.

これによれば、道路の交通量と照度の両者に共に応じた好適な調光度により道路を照明できるので、節電を図りつつ交通安全性の向上を図ることができる。   According to this, since the road can be illuminated with a suitable dimming degree corresponding to both the traffic volume and the illuminance of the road, it is possible to improve traffic safety while saving power.

図３は本発明の第３実施形態に係る照明制御システム１Ｂの一部切欠正面図である。この照明制御システム１Ｂは、第３の照明装置である第３街路灯２Ｘを具備している。   FIG. 3 is a partially cutaway front view of a lighting control system 1B according to a third embodiment of the present invention. The lighting control system 1B includes a third street light 2X that is a third lighting device.

この第３街路灯２Ｘは、地面等に立設される所要高さの円柱状または角柱状のポール２Ｘ１の上端部に、照明器具２Ｘ２を直角等所要角で固着している。照明器具２Ｘ２は、そのＨＩＤランプ等所要ランプの近傍に照度センサ２Ｘ３を配設している。   In this third street light 2X, a lighting fixture 2X2 is fixed at a required angle such as a right angle to the upper end of a columnar or prismatic pole 2X1 of a required height standing on the ground or the like. The luminaire 2X2 is provided with an illuminance sensor 2X3 in the vicinity of a required lamp such as an HID lamp.

また、ポール２Ｘ１には、アンテナＡＮＴを備えた通信装置２Ｘ４と、マイクロプロセッサ等からなる制御装置２Ｘ５とを設けている。   The pole 2X1 is provided with a communication device 2X4 provided with an antenna ANT, and a control device 2X5 composed of a microprocessor or the like.

制御装置２Ｘ５は、上記第１，第２調光器２Ａ５，２Ｂ５，…、２ｐ４とほぼ同様の点消灯、調光機能と、通信装置２Ｘ４の通信機能を中継可能に制御する通信制御機能と、第１の玉切れ予測手段とを具備している。   The control device 2X5 includes a lighting control and dimming function substantially similar to those of the first and second dimmers 2A5, 2B5,..., 2p4, and a communication control function for controlling the communication function of the communication device 2X4 so as to be relayable. 1st ball piece prediction means.

図４はこの第１の玉切れ予測手段の処理プログラムのフローチャートであり、図中、Ｓに数字を付した符号はこのフローチャートの各ステップを示す。   FIG. 4 is a flowchart of the processing program of the first ball-out predicting means. In the figure, the reference numerals with numerals added to S indicate the steps of the flowchart.

すなわち、第１の玉切れ予測手段は、照度センサ２Ｘ３により検出された照度検出値が予め設定したランプ寿命末期時の照度まで低下したときに、玉切れ予測を行なう点に特徴がある。すなわち、第１の玉切れ予測手段は、その処理プログラムをスタートさせた後、まずＳ１で、通信装置２Ｘ４により受信された制御信号を解読して照明器具２Ｘ２を点灯させる要求である街路灯点灯制御要求があるか否か繰り返し判断し、ＹＥＳのときに、Ｓ２で照明器具２Ｘ２を点灯させる。この点灯要求は、照度センサ２Ｘ３の照度検出値を読み込む制御装置２Ｘ５自体から生成させ出力してもよい。また、通信装置２Ｘ４により受信した図示しない中央制御装置や他の第１調光器２Ａ５，２Ｂ５，…から受信した光出力制御信号中の点灯制御信号でもよい。   In other words, the first out-of-ball prediction means is characterized in that the out-of-ball prediction is performed when the detected illuminance value detected by the illuminance sensor 2X3 falls to a preset illuminance at the end of the lamp life. That is, the first ball break prediction means starts the processing program, and first, in S1, the street light lighting control is a request for lighting the lighting fixture 2X2 by decoding the control signal received by the communication device 2X4. Whether or not there is a request is repeatedly determined, and when YES, the lighting fixture 2X2 is turned on in S2. This lighting request may be generated and output from the control device 2X5 itself that reads the detected illuminance value of the illuminance sensor 2X3. Moreover, the lighting control signal in the light output control signal received from the central controller which is not shown in figure received from the communication apparatus 2X4, and other 1st dimmer 2A5, 2B5, ... may be sufficient.

次にＳ３で、このときの照度検出値を照度センサ２Ｘ３から読み込む。   Next, in S3, the detected illuminance value at this time is read from the illuminance sensor 2X3.

この後、Ｓ４で、この読み込んだ照度検出値を予め設定してある所要の照度基準値と比較する。 照度基準値は、一般的なランプの寿命末期が初期照度の７５〜８０％程度の照度レベルであるので、ランプ取付時に全光束点灯させたときの照度検出値の例えば８０％前後に設定されている。   Thereafter, in S4, the read illuminance detection value is compared with a predetermined illuminance reference value set in advance. The illuminance reference value is set to, for example, about 80% of the illuminance detection value when the total luminous flux is lit when the lamp is mounted, since the end of life of a general lamp is an illuminance level of about 75 to 80% of the initial illuminance. Yes.

そして、この照度基準値よりも照度検出値の方が低いとき（ＹＥＳ）は、ランプ寿命末期に達したと判断して次のＳ５へ進み、ＮＯのときはＳ６へジャンプする。   If the detected illuminance value is lower than the illuminance reference value (YES), it is determined that the end of the lamp life has been reached, and the process proceeds to the next S5. If NO, the process jumps to S6.

Ｓ５では、玉切れ警告を通信装置２Ｘ４から監視装置の一例である図示しない中央制御装置へ直接、または図１，図２で示す複数の通信装置２Ａ３，２Ｂ３，…、２ｐ３の中継を介して自己に記憶されている固有のアドレスとともに送信する。   In S5, a ball-out warning is sent directly from the communication device 2X4 to a central control device (not shown) which is an example of a monitoring device, or via relays of a plurality of communication devices 2A3, 2B3,. With a unique address stored in

一方、Ｓ６では、街路灯消灯制御要求があるか否かを繰り返し判断する。この消灯制御要求も第３街路灯２Ｘ自体の制御装置２Ｘ５から生成出力されたものでもよく、または他の街路灯２の通信装置２Ａ３，２Ｂ３，…、２ｐ３から直接または中継を介して受信した制御信号でもよい。   On the other hand, in S6, it is repeatedly determined whether there is a street light extinction control request. This turn-off control request may also be generated and output from the control device 2X5 of the third street light 2X itself, or the control received from the communication devices 2A3, 2B3,. It may be a signal.

そして、次のＳ７では、この街路灯消灯制御要求に従ってランプを消灯させる。この後、再びＳ１へ戻り、以下のステップを繰り返す。   In the next S7, the lamp is turned off in accordance with the street lamp turn-off control request. Thereafter, the process returns to S1 again, and the following steps are repeated.

したがって、この照明制御システム１Ｂによれば、ランプの寿命末期の警告が自動的に中央制御装置に送信され通知されるので、監視員が街路灯２の玉切れの目視チェックのために巡回する必要がなく、玉切れによるランプ交換に伴うコストを低減することができる。   Therefore, according to the lighting control system 1B, a warning at the end of the lamp life is automatically transmitted to the central control device and notified, so that it is necessary for the supervisor to go around for a visual check of the street lamp 2 being blown out. Therefore, it is possible to reduce the cost associated with lamp replacement due to out of ball.

また、玉切れを判断するための照度基準値をランプ初期照度の７０〜８０％程度に設定してランプ寿命が尽きるまでに余裕を持たせているので、玉切れの前にランプを交換することにより、玉切れによる不点灯を未然に防止することができるうえに、玉切れ予測精度の向上を図ることができる。   In addition, since the illuminance reference value for judging the burnout is set to about 70 to 80% of the initial lamp illuminance, there is a margin until the lamp life is exhausted. Thus, non-lighting due to ball breakage can be prevented, and the accuracy of ball breakage prediction can be improved.

図５は本発明の第４実施形態に係る照明制御システム１Ｃの一部切欠正面図である。この照明制御システム１Ｂは、第４の照明装置である第４街路灯２Ｙを具備している。   FIG. 5 is a partially cutaway front view of a lighting control system 1C according to a fourth embodiment of the present invention. The lighting control system 1B includes a fourth street light 2Y that is a fourth lighting device.

この第４街路灯２Ｙは、地面等に立設される所要高さの円柱状または角柱状のポール２Ｙ１の上端部に、照明器具２Ｙ２を直角等所要角で固着している。   In the fourth street light 2Y, a lighting fixture 2Y2 is fixed at a required angle such as a right angle to an upper end portion of a columnar or prismatic pole 2Y1 having a required height standing on the ground or the like.

また、ポール２Ｙ１には、アンテナＡＮＴを備えた通信装置２Ｙ１と、マイクロプロセッサ等からなる制御装置２Ｙ５と、を設けている。   The pole 2Y1 is provided with a communication device 2Y1 provided with an antenna ANT, and a control device 2Y5 composed of a microprocessor or the like.

制御装置２Ｙ５は、上記第１，第２調光器２Ａ５，２Ｂ５，…、２ｐ４とほぼ同様の点消灯、調光機能と、通信装置２Ｙ４の通信機能を中継可能に制御する通信制御機能と、第２の玉切れ予測手段とを具備している。   The control device 2Y5 includes a lighting control and dimming function substantially the same as the first and second dimmers 2A5, 2B5,..., 2p4, and a communication control function for controlling the communication function of the communication device 2Y4 to be relayable. 2nd ball piece prediction means.

図４はこの第２の玉切れ予測手段の処理プログラムのフローチャートであり、図中、Ｓに数字を付した符号はこのフローチャートの各ステップを示す。   FIG. 4 is a flowchart of the processing program of the second ball-out prediction means. In the figure, the reference numerals with numerals added to S indicate the steps of this flowchart.

すなわち、第２の玉切れ予測手段は、照明器具２Ｙ２のランプの累積点灯時間が予め設定したランプ寿命末期までの累積点灯時間に達したときに、ランプ寿命末期の予測を行なう点に特徴がある。   That is, the second out-of-ball prediction means is characterized in that when the cumulative lighting time of the lamp of the lighting fixture 2Y2 reaches a preset cumulative lighting time up to the end of the lamp life, the end of the lamp life is predicted. .

つまり、第２の玉切れ予測手段は、その処理プログラムをスタートさせた後、まずＳ１１で、通信装置２Ｙ４により受信された制御信号を解読して照明器具２Ｙを点灯させる要求である街路灯点灯制御要求があるか否か繰り返し判断し、ＹＥＳのときに、Ｓ１２で照明器具２Ｙを点灯させる。この点灯要求は、通信装置２Ｙ４により受信した図示しない中央制御装置や他の第１調光器２Ａ５，２Ｂ５，…から受信した光質制御装置中の点灯制御信号でもよい。   In other words, after the second ball-out prediction means starts its processing program, first, in S11, the street lamp lighting control is a request for lighting the lighting fixture 2Y by decoding the control signal received by the communication device 2Y4. It is repeatedly determined whether or not there is a request, and if YES, the lighting fixture 2Y is turned on in S12. This lighting request may be a lighting control signal in the light quality control device received from the central control device (not shown) received by the communication device 2Y4 or the other first dimmers 2A5, 2B5,.

この後、Ｓ１３で、ランプ点灯とほぼ同時にランプの点灯時間の計測を開始し、次のＳ１４で、街路灯消灯制御要求があるか否か繰り返し判断する。この街路灯消灯制御要求は第４街路灯２Ｙ自体の制御装置２Ｙ５により生成させてもよく、通信装置２Ｙ４により受信した他の街路灯２，２，…の通信装置２Ａ４，２Ｂ４，…、２ｐ４のいずれから直接、またはこれらの中継を介して受信した街路灯消灯制御要求信号でもよい。   Thereafter, in S13, the measurement of the lamp lighting time is started almost simultaneously with the lamp lighting, and in the next S14, it is repeatedly determined whether or not there is a street lamp extinguishing control request. This street lamp turn-off control request may be generated by the control device 2Y5 of the fourth street lamp 2Y itself, and the communication devices 2A4, 2B4,..., 2p4 of the other street lamps 2, 2,. The street light extinction control request signal may be received directly from any of these or via these relays.

このＳ１４で街路灯消灯制御要求があったとき（ＹＥＳ）は、次のＳ１５で、第４街路灯２Ｙの照明器具２Ｙ２のランプを消灯させ、さらに次のＳ１６で、点灯時間の計測を終了させる。   When there is a street lamp turn-off control request in S14 (YES), the lamp of the lighting fixture 2Y2 of the fourth street lamp 2Y is turned off in the next S15, and the measurement of the lighting time is finished in the next S16. .

この後Ｓ１７で、この計測した点灯時間データを通信装置２Ｙ４から図示しない中央制御装置へ送信させ、第２の玉切れ予測手段の点灯時間計測データをクリアし、次の点灯時間を計測するために再びＳ１１へ戻り、以下のステップを繰り返す。   Thereafter, in S17, the measured lighting time data is transmitted from the communication device 2Y4 to a central control device (not shown), the lighting time measurement data of the second ball-out prediction means is cleared, and the next lighting time is measured. Returning to S11 again, the following steps are repeated.

一方、中央制御装置は、第４街路灯２Ｙから受信した点灯時間計測データをメモリに記録し、これ以後の点灯時間計測データを加算して累積点灯時間を演算する。この累積点灯時間が予め設定した所要の基準時間に達したと判断したときに玉切れ警告を通知する。   On the other hand, the central controller records the lighting time measurement data received from the fourth street lamp 2Y in the memory, and adds the subsequent lighting time measurement data to calculate the cumulative lighting time. When it is determined that the accumulated lighting time has reached a predetermined reference time set in advance, an out-of-ball warning is notified.

なお、この基準時間は、一般的なランプ寿命時間の７０〜８０％程度に設定することが望ましい。これによれば、玉切れ警告を通知した後も暫時点灯が可能であるので、ランプ交換までに不点に陥る事態を回避することができる。   The reference time is desirably set to about 70 to 80% of a general lamp life time. According to this, since it is possible to light for a while even after notifying the out-of-ball warning, it is possible to avoid a situation in which there is a problem before replacing the lamp.

また、この照明制御システム１Ｃによっても、玉切れ警告を自動的に通知することができるので、玉切れの目視チェックによる精度低下とコストアップを未然に防止することができる。   In addition, this lighting control system 1C can automatically notify a ball-out warning, thereby preventing a reduction in accuracy and an increase in cost due to a visual check of the ball-out.

なお、この実施形態では、中央制御装置によりランプの累積点灯時間を演算し、玉切れ予測警告通知まで行なうように構成した場合について説明したが、本発明はこれに限定されるものではなく、例えば、この累積点灯時間の演算から玉切れ予測警告通知までを第４街路灯２Ｙの制御装置２Ｙ５により実行するように構成し、中央制御装置はこの玉切れ予測警告通知のみを受信するように構成してもよい。   In this embodiment, the case where the central control device calculates the cumulative lighting time of the lamp and is configured to perform the notification of out-of-balloon warning is described, but the present invention is not limited to this, for example, From the calculation of the cumulative lighting time until the out of ball prediction warning notification is configured to be executed by the control device 2Y5 of the fourth street light 2Y, and the central control unit is configured to receive only this out of ball prediction warning notification. May be.
