　表示制御装置１０は、第１の検出センサ７及び第２の検出センサ８のそれぞれによる歯車板６ａの検出回数及び検出タイミングに基づいて、エスカレータ１の運転速度及び運転方向を判定する。 The display control device 10 determines the operation speed and the operation direction of the escalator 1 based on the number of detections and the detection timing of the gear plate 6a by each of the first detection sensor 7 and the second detection sensor 8.
　エスカレータ１が上昇運転している場合には、同一の歯車板６ａは、第１の検出センサ７により検出された後、第２の検出センサ８により検出される。反対に、エスカレータ１が下降運転をしている場合には、同一の歯車板６ａは、第２の検出センサ８により検出された後、第１の検出センサ７により検出される。従って、表示制御装置１０は、第１の検出センサ７及び第２の検出センサ８のそれぞれによる歯車板６ａの検出タイミングにより、回転方向を検出することができる。また、表示制御装置１０は、一定時間内において、第１の検出センサ７及び第２の検出センサ８の少なくともいずれか一方による歯車板６ａの検出回数により、回転速度を検出することができる。 When the escalator 1 is in the ascending operation, the same gear plate 6 a is detected by the second detection sensor 8 after being detected by the first detection sensor 7. Conversely, when the escalator 1 is performing the descending operation, the same gear plate 6 a is detected by the first detection sensor 7 after being detected by the second detection sensor 8. Therefore, the display control device 10 can detect the rotation direction based on the detection timing of the gear plate 6a by each of the first detection sensor 7 and the second detection sensor 8. Further, the display control device 10 can detect the rotation speed based on the number of times the gear plate 6a is detected by at least one of the first detection sensor 7 and the second detection sensor 8 within a certain time.
　表示制御装置１０は、第１の検出センサ７及び第２の検出センサ８による歯車板６ａの検出結果を、信号線１３を介して取得する。また、制御盤９は、エスカレータ１の運転動作を制御するものである。そこで、表示制御装置１０は、制御盤９により生成されたエスカレータ１の停止状態を含む運転状況の情報を、信号線１４を介して取得する。 The display control device 10 acquires the detection result of the gear plate 6a by the first detection sensor 7 and the second detection sensor 8 via the signal line 13. The control panel 9 controls the operation of the escalator 1. Therefore, the display control device 10 obtains, via the signal line 14, information on the operating state including the stop state of the escalator 1 generated by the control panel 9.
　表示制御装置１０は、第１の検出センサ７及び第２の検出センサ８による歯車板６ａの検出結果に基づいて、エスカレータ１の運転速度及び運転方向を判定する。また、表示制御装置１０は、これらの運転速度及び運転方向に合わせて、表示装置３に表示するメッセージの表示速度及び表示方向を制御する。 The display control device 10 determines the operation speed and the operation direction of the escalator 1 based on the detection result of the gear plate 6a by the first detection sensor 7 and the second detection sensor 8. The display control device 10 controls the display speed and the display direction of the message displayed on the display device 3 in accordance with the operation speed and the operation direction.
　本実施の形態１に係る表示制御システムにおいて、表示制御装置１０は、表示装置３の周辺に設けられた照度センサ１１及び乗客センサ１２の検出結果に基づいて、表示装置３の表示輝度を制御する。照度センサ１１及び乗客センサ１２は、信号線１６により表示制御装置１０と接続されている。 In the display control system according to the first embodiment, the display control device 10 controls the display brightness of the display device 3 based on the detection results of the illuminance sensor 11 and the passenger sensor 12 provided around the display device 3. . The illuminance sensor 11 and the passenger sensor 12 are connected to the display control device 10 by a signal line 16.
　図１において、表示装置３は、複数の表示パネル３ａから構成されている。それぞれの表示パネル３ａには、照度センサ１１と乗客センサ１２とが１つずつ設けられている。すなわち、照度センサ１１と乗客センサ１２とが一対となったものが、表示パネル３ａの数だけ複数配列されている。 In FIG. 1, the display device 3 is composed of a plurality of display panels 3a. Each display panel 3a is provided with one illuminance sensor 11 and one passenger sensor 12. That is, a plurality of pairs of the illuminance sensors 11 and the passenger sensors 12 are arranged by the number of the display panels 3a.
　ただし、照度センサ１１は、必須の構成要件ではない。表示制御装置１０は、乗客センサ１２があれば、乗客の位置に応じて、表示装置３の輝度を変更する表示制御を行い、消費電力の削減を図ることができる。 However, the illuminance sensor 11 is not an essential component. If the passenger sensor 12 is provided, the display control device 10 can perform display control to change the luminance of the display device 3 according to the position of the passenger, thereby reducing power consumption.
　表示制御装置１０は、それぞれの乗客センサ１２による検出結果に基づいて、エスカレータ１上での乗客の位置を特定する。さらに、表示制御装置１０は、特定された乗客の位置から視認される表示パネル３ａに関しては、より明るい輝度で表示させることで、視認性の向上を図ることができる。一方、表示制御装置１０は、特定された乗客の位置から視認されない表示パネル３ａに関しては、より暗い輝度で表示させることで、消費電力の削減を図ることができる。 The display control device 10 specifies the position of the passenger on the escalator 1 based on the detection result of each passenger sensor 12. Further, the display control device 10 can improve the visibility by displaying the display panel 3a visually recognized from the specified position of the passenger with brighter brightness. On the other hand, the display control device 10 can reduce power consumption by displaying the display panel 3a that is not visually recognized from the specified position of the passenger with darker luminance.
　具体的には、表示制御装置１０は、より明るい輝度で表示パネル３ａの表示を行わせる際の高レベルの輝度係数と、より暗い輝度で表示パネル３ａの表示を行わせる際の中レベルの輝度係数とを、予め記憶部に記憶させておくことができる。この場合、表示制御装置１０は、乗客センサ１２による検出結果に基づいて、それぞれの表示パネル３ａの輝度係数を可変設定することで、表示輝度を制御することができる。 Specifically, the display control device 10 controls the high-level luminance coefficient when displaying the display panel 3a with brighter luminance and the medium-level luminance when displaying the display panel 3a with darker luminance. The coefficient can be stored in the storage unit in advance. In this case, the display control device 10 can control the display luminance by variably setting the luminance coefficient of each display panel 3a based on the detection result by the passenger sensor 12.
　さらに、照度センサ１１が設置されている場合には、表示制御装置１０は、照度センサ１１の設置場所における照度データを取得することができる。従って、表示制御装置１０は、取得した照度データに応じて、さらに、表示輝度を制御することができる。具体的には、表示制御装置１０は、周囲環境が暗く、より低い照度データが得られた場合には、輝度を下げるように表示輝度を制御する。一方、表示制御装置１０は、周囲環境が明るく、より高い照度データが得られた場合には、輝度を上げるように表示輝度を制御する。この結果、表示制御装置１０は、照度センサ１１により検出された照度データに基づいて、視認性の改善、及び消費電力の削減を図ることができる。 Further, when the illuminance sensor 11 is installed, the display control device 10 can acquire illuminance data at the installation location of the illuminance sensor 11. Therefore, the display control device 10 can further control the display luminance according to the acquired illuminance data. Specifically, when the surrounding environment is dark and lower illuminance data is obtained, the display control device 10 controls the display luminance so as to reduce the luminance. On the other hand, when the surrounding environment is bright and higher illuminance data is obtained, the display control device 10 controls the display luminance so as to increase the luminance. As a result, the display control device 10 can improve the visibility and reduce the power consumption based on the illuminance data detected by the illuminance sensor 11.
　図２は、上述した表示制御システムに備えられる表示装置３の細部構成を拡大して示した図である。但し、図２に示す表示装置３は、図１に示した２台の表示装置３のうちの下階側に設けられた方を示している。 FIG. 2 is an enlarged view showing a detailed configuration of the display device 3 provided in the display control system described above. However, the display device 3 shown in FIG. 2 shows the one provided on the lower floor side of the two display devices 3 shown in FIG.
　図１及び図２を参照すれば、表示装置３に設けられた複数の表示パネル３ａのそれぞれには、表示メッセージの文字が表示される。照度センサ１１は、表示装置３の周辺の照度を検出するものであり、表示装置３に設置される。例えば、照度センサ１１は、図２に示したように、踏段２における１段間隔で７個の表示パネル３ａのそれぞれ下部位置に設置されることが望ましい。 1 and 2, the characters of the display message are displayed on each of the plurality of display panels 3 a provided on the display device 3. The illuminance sensor 11 detects illuminance around the display device 3 and is installed on the display device 3. For example, as shown in FIG. 2, it is desirable that the illuminance sensor 11 be installed at a lower position of each of the seven display panels 3 a at one-step intervals on the steps 2.
　乗客センサ１２は、踏段２上の乗客の有無を検出するもので、表示装置３に設置される。例えば、乗客センサ１２は、図２に示されるように、踏段２における１段間隔で７個の表示パネル３ａのそれぞれ下部位置に、照度センサ１１と対を成すように設置されることが望ましい。このように配置されることで、乗客センサ１２は、表示装置３の周辺を通過する利用者の有無を検出することができる。 The passenger sensor 12 detects the presence or absence of a passenger on the steps 2 and is installed on the display device 3. For example, as shown in FIG. 2, it is desirable that the passenger sensor 12 be installed at a lower position of each of the seven display panels 3 a at one-step intervals on the steps 2 so as to form a pair with the illuminance sensor 11. With this arrangement, the passenger sensor 12 can detect the presence or absence of a user passing around the display device 3.
　表示制御装置１０は、第１の検出センサ７及び第２の検出センサ８による検出結果に基づいて、エスカレータ１の運転方向及び運転速度を判定する。さらに、表示制御装置１０は、運転方向及び運転速度に加えて、乗客センサ１２による検出結果を考慮することで、踏段２の移動に伴う乗客の到達位置を予測することができる。 The display control device 10 determines the driving direction and the driving speed of the escalator 1 based on the detection results of the first detection sensor 7 and the second detection sensor 8. Further, the display control device 10 can predict the arrival position of the passenger accompanying the movement of the steps 2 by considering the detection result of the passenger sensor 12 in addition to the driving direction and the driving speed.
　そして、表示制御装置１０は、予測した到達位置から乗客が視認可能な位置に設置されている表示パネル３ａに関しては、より明るい輝度で表示させることで、視認性の向上を図ることができる。一方、表示制御装置１０は、予測した到達位置から乗客が視認できない位置に設置されている表示パネル３ａに関しては、より暗い輝度で表示させることで、消費電力の削減を図ることができる。 {Circle around (5)} The display control device 10 can improve the visibility by displaying the display panel 3a installed at a position where the passenger can be visually recognized from the predicted arrival position with brighter brightness. On the other hand, the display control device 10 can reduce the power consumption by displaying the display panel 3a installed at a position where the passenger cannot be visually recognized from the predicted arrival position with darker luminance.
　また、表示制御装置１０は、予測した到達位置に設置されている照度センサ１１から照度データを取得することで、設置環境における照度に応じて表示パネル３ａの表示輝度をさらに制御することもできる。 The display control device 10 can further control the display luminance of the display panel 3a according to the illuminance in the installation environment by acquiring the illuminance data from the illuminance sensor 11 installed at the predicted arrival position.
　なお、表示制御装置１０は、視認性を向上させるための高レベルの輝度係数と、消費電力の低減を図るための中レベルの輝度係数との切り替えによる２段階の表示輝度制御を行うことに加え、エスカレータ１が使用停止中には、最も輝度を下げるための低レベルの輝度係数をさらに考慮して、３段階の表示輝度制御を行うこともできる。 The display control device 10 performs two-stage display luminance control by switching between a high-level luminance coefficient for improving visibility and a medium-level luminance coefficient for reducing power consumption. When the escalator 1 is not in use, three-stage display brightness control can be performed by further considering a low-level brightness coefficient for lowering the brightness.
　換言すると、表示制御装置１０は、第１の検出センサ７及び第２の検出センサ８による検出結果に基づいて判定したエスカレータ１の運転速度及び運転方向と、乗客センサ１２による検出結果と、制御盤９から取得した運転状況の情報とに応じて、それぞれの表示パネル３ａの表示輝度制御を行うことができる。さらに、表示制御装置１０は、照度センサ１１で検出される照度データを利用できる場合には、設置環境の照度に応じて、それぞれの表示パネル３ａの表示輝度制御を行うことができる。 In other words, the display control device 10 determines the driving speed and the driving direction of the escalator 1 determined based on the detection results obtained by the first detection sensor 7 and the second detection sensor 8, the detection results obtained by the passenger sensor 12, and the control panel. 9, the display brightness control of each display panel 3a can be performed in accordance with the information on the driving situation acquired from FIG. Furthermore, when the illuminance data detected by the illuminance sensor 11 can be used, the display control device 10 can control the display brightness of each display panel 3a according to the illuminance of the installation environment.
　これにより、表示装置３の表示輝度を好適に制御することが可能となる表示制御システム及び表示制御方法を実現できる。この結果、表示パネル３ａにおける表示メッセージの内容を、確実に乗客に伝えることができる。また、乗客がいない位置において、表示装置３の表示が継続して行われることがない。このため、表示装置３の消費電力が無駄にならない。 Thereby, it is possible to realize a display control system and a display control method capable of suitably controlling the display luminance of the display device 3. As a result, the contents of the display message on the display panel 3a can be reliably transmitted to the passenger. Further, the display on the display device 3 is not continuously performed at a position where there is no passenger. Therefore, the power consumption of the display device 3 is not wasted.
　表示制御装置１０による具体的な表示制御機能としては、次のような手法が考えられる。表示制御装置１０は、乗客センサ１２により乗客有りの状態を検出したときには、乗客有り用の高レベルの輝度係数を選択する。さらに、表示制御装置１０は、照度センサ１１で検出された照度データに基づいて、基準となる照度データを設定する。そして、表示制御装置１０は、基準となる照度データ及び乗客有り用の高レベルの輝度係数に基づいて算出した輝度に応じて、それぞれの表示パネル３ａの表示輝度を変更する制御を行う。 As a specific display control function of the display control device 10, the following method is conceivable. When detecting the presence of a passenger by the passenger sensor 12, the display control device 10 selects a high-level luminance coefficient for the presence of a passenger. Furthermore, the display control device 10 sets reference illuminance data based on the illuminance data detected by the illuminance sensor 11. Then, the display control device 10 performs control to change the display brightness of each display panel 3a according to the illuminance data serving as a reference and the brightness calculated based on the high-level brightness coefficient for the presence of a passenger.
　一方、表示制御装置１０は、乗客センサ１２により乗客無しの状態を検出したときには、乗客無し用の中レベルの輝度係数を選択する。さらに、表示制御装置１０は、照度センサ１１で検出された照度データに基づいて、基準となる照度データを設定する。そして、表示制御装置１０は、基準となる照度データ及び乗客無し用の中レベルの輝度係数に基づいて算出した輝度に応じて、それぞれの表示パネル３ａの表示輝度を変更する制御を行う。 On the other hand, when the display sensor 10 detects the absence of a passenger by the passenger sensor 12, the display controller 10 selects a medium-level luminance coefficient for the absence of a passenger. Furthermore, the display control device 10 sets reference illuminance data based on the illuminance data detected by the illuminance sensor 11. Then, the display control device 10 performs control to change the display luminance of each display panel 3a according to the illuminance data serving as a reference and the luminance calculated based on the medium-level luminance coefficient for no passenger.
　更に、表示制御装置１０は、制御盤９から取得したエスカレータ１の運転状況の情報により、エスカレータ１が停止中であると判断できる場合には、停止中用の低レベルの輝度係数を選択する。そして、エスカレータ１が停止中の場合には、表示制御装置１０は、乗客センサ１２及び照度センサ１１のそれぞれの検出結果を考慮せずに、停止中用の低レベルの輝度係数に基づいて算出した輝度に応じて、それぞれの表示パネル３ａの表示輝度を変更する制御を行う。 (4) If the display control device 10 can determine that the escalator 1 is stopped based on the information on the operation status of the escalator 1 acquired from the control panel 9, the display control device 10 selects a low-level luminance coefficient for the stopped state. Then, when the escalator 1 is stopped, the display control device 10 calculates based on the low-level luminance coefficient for the stopped state without considering each detection result of the passenger sensor 12 and the illuminance sensor 11. Control is performed to change the display brightness of each display panel 3a according to the brightness.
　ところで、上述した表示制御装置１０の各機能は、表示制御方法として、換言することができる。この場合の表示制御方法は、表示装置３の周辺の乗客の有無を検出する乗客検出ステップと、エスカレータ１に設けられた踏段２に沿って設置された表示装置３の表示輝度を制御する表示制御ステップと、に大別される。 By the way, each function of the display control device 10 described above can be paraphrased as a display control method. The display control method in this case includes a passenger detection step of detecting the presence or absence of a passenger in the vicinity of the display device 3 and a display control for controlling the display brightness of the display device 3 installed along the steps 2 provided on the escalator 1. Steps are roughly divided into:
　乗客検出ステップでは、表示制御装置１０は、乗客センサ１２による検出結果に基づいて、乗客の有無を判断する。この際、表示制御装置１０は、第１の検出センサ７及び第２の検出センサ８による検出結果に基づいて判定したエスカレータ１の運転方向及び運転速度を考慮することで、乗客の到達位置を予測することができる。 In the passenger detection step, the display control device 10 determines the presence or absence of a passenger based on the detection result of the passenger sensor 12. At this time, the display control device 10 predicts the arrival position of the passenger by considering the driving direction and the driving speed of the escalator 1 determined based on the detection results by the first detection sensor 7 and the second detection sensor 8. can do.
　表示制御ステップでは、表示制御装置１０は、乗客検出ステップによる乗客有無の検出結果、および乗客の到達位置の予測結果に応じて、予め設定された異なるレベルの輝度係数に基づいて、輝度を算出する。さらに、表示制御装置１０は、輝度の算出結果に応じて、それぞれの表示パネル３ａの表示輝度を変更する制御を行う。 In the display control step, the display control device 10 calculates the luminance based on luminance coefficients of different levels set in advance according to the detection result of the presence or absence of the passenger in the passenger detection step and the prediction result of the arrival position of the passenger. . Further, the display control device 10 performs control for changing the display brightness of each display panel 3a according to the calculation result of the brightness.
　上記表示制御方法は、表示装置３の周辺の照度を検出する照度検出ステップを有しても良い。この場合、表示制御ステップでは、表示制御装置１０は、輝度を算出する際に、照度検出ステップにおいて照度センサ１１の検出結果に基づいて設定される基準となる照度データを考慮して輝度を補正することができる。 The display control method may include an illuminance detecting step of detecting illuminance around the display device 3. In this case, in the display control step, when calculating the luminance, the display control device 10 corrects the luminance in consideration of the reference illuminance data set based on the detection result of the illuminance sensor 11 in the illuminance detection step. be able to.
　図３は、上述した表示制御システムの動作処理を示すフローチャートである。このフローチャートを用いて、表示制御装置１０により実行される一連の表示制御方法について説明する。 FIG. 3 is a flowchart showing the operation processing of the display control system described above. A series of display control methods executed by the display control device 10 will be described with reference to this flowchart.
　まず、ステップＳ３０１において、表示制御装置１０は、制御盤９からエスカレータ１の運転情報を取得し、エスカレータ１が運転中であるか否かの判定を行う。この判定の結果、エスカレータ１が運転中でなく、停止中である場合、ステップＳ３０２に進み、表示制御装置１０は、予め設定された停止中用の低レベルの輝度係数を選択する。この後、ステップＳ３０３に進み、表示制御装置１０は、停止中用の低レベルの輝度係数に基づいて算出した輝度に応じて、各表示装置３の表示輝度を変更する制御を行う。これにより、各表示装置３の表示照度を変更する処理が行われる。この後は、動作処理を終了する。 First, in step S301, the display control device 10 acquires operation information of the escalator 1 from the control panel 9, and determines whether the escalator 1 is operating. If the result of this determination is that the escalator 1 is not operating but is stopped, the process proceeds to step S302, and the display control device 10 selects a preset low-level luminance coefficient for stopping. Thereafter, the process proceeds to step S303, and the display control device 10 performs control to change the display brightness of each display device 3 according to the brightness calculated based on the low-level brightness coefficient for the stopped state. Thereby, the process of changing the display illuminance of each display device 3 is performed. Thereafter, the operation processing ends.
　これに対し、ステップＳ３０１においてエスカレータ１が運転中であると判定された場合には、ステップＳ３０４に進み、表示制御装置１０は、乗客センサ１２の検出情報から乗客のいる踏段２を検出する。この後、ステップＳ３０５に進み、表示制御装置１０は、第１の検出センサ７及び第２の検出センサ８による検出結果から特定した現在の運転速度および運転方向に基づいて、ｎ秒後の乗客位置を予測する。ｎは、例えば１とする場合を例示できるが、エスカレータ１の運転速度、表示装置３が有する表示パネル３ａの数に応じて、適宜変更することが好ましい。また、ｎを複数設定することで、表示制御装置１０は、時間経過に伴う利用者の到達位置を予測することもできる。 On the other hand, when it is determined in step S301 that the escalator 1 is operating, the process proceeds to step S304, and the display control device 10 detects the step 2 where the passenger is present from the detection information of the passenger sensor 12. Thereafter, the process proceeds to step S305, where the display control device 10 determines the passenger position after n seconds based on the current driving speed and driving direction specified from the detection results by the first detection sensor 7 and the second detection sensor 8. To predict. For example, n may be set to 1, for example, but it is preferable to appropriately change n according to the operating speed of the escalator 1 and the number of display panels 3a included in the display device 3. Further, by setting a plurality of n, the display control device 10 can also predict the user's arrival position over time.
　引き続き、ステップＳ３０６に進み、表示制御装置１０は、表示装置３が有する表示パネル３ａの個数分のループ処理を、以降のステップＳ３０７～ステップＳ３１２について行う。図２に示した具体例では、表示装置３は、２台あり、それぞれの表示装置３は、７個の表示パネル３ａを有する。このため、総計１４個の表示パネル３ａが、表示制御装置１０による表示制御対象となる。 Then, the process proceeds to step S306, where the display control device 10 performs a loop process for the number of display panels 3a included in the display device 3 for the subsequent steps S307 to S312. In the specific example shown in FIG. 2, there are two display devices 3, and each display device 3 has seven display panels 3a. For this reason, a total of 14 display panels 3a are display control targets by the display control device 10.
　ステップＳ３０７において、表示制御装置１０は、個々の表示パネル３ａごとに、表示パネル３ａを視認可能な乗客がいるか否かを判定する。具体的には、表示制御装置１０は、表示パネル３ａの位置が、ステップＳ３０５で予測したｎ秒後の乗客位置に対応するか否かの判定を行う。 In step S307, the display control device 10 determines, for each display panel 3a, whether or not there is a passenger who can view the display panel 3a. Specifically, the display control device 10 determines whether or not the position of the display panel 3a corresponds to the passenger position after n seconds predicted in step S305.
　この判定の結果、乗客有りと判定した場合、ステップＳ３０８に進み、表示制御装置１０は、乗客有用の高レベルの輝度係数を選択する。これに対し、乗客無しと判定した場合、ステップＳ３０９に進み、表示制御装置１０は、乗客無し用の中レベルの輝度係数を選択する。 If the result of this determination is that there is a passenger, the process proceeds to step S308, and the display control device 10 selects a high-level luminance coefficient useful for passengers. On the other hand, when it is determined that there is no passenger, the process proceeds to step S309, and the display control device 10 selects a medium-level luminance coefficient for no passenger.
　ステップＳ３０８またはステップＳ３０９の後、ステップＳ３１０に進み、表示制御装置１０は、各表示装置３のそれぞれの表示パネル３ａに対応して設置された照度センサ１１から照度データを取り込み、基準となる照度データを決定する。表示パネル３ａの輝度を決定するための基準となる照度データとしては、過去の照度データの平均値を使用しても良い。また、基準となる照度データとしては、目標とした表示パネル３ａの照度データと、その前後に存在する表示パネル３ａの照度データとの平均値を使用しても良い。 After step S308 or step S309, the process proceeds to step S310, in which the display control device 10 captures illuminance data from the illuminance sensors 11 installed corresponding to the respective display panels 3a of the respective display devices 3, and sets the reference illuminance data. To determine. As illuminance data serving as a reference for determining the luminance of the display panel 3a, an average value of past illuminance data may be used. As the reference illuminance data, an average value of the target illuminance data of the display panel 3a and the illuminance data of the display panels 3a existing before and after the target may be used.
　更に、ステップＳ３１１に進み、表示制御装置１０は、ステップＳ３１０で決定した基準となる照度データと、ステップＳ３０８で選択した乗客有り用の高レベルの輝度係数またはステップＳ３０９で選択した乗客無し用の中レベルの輝度係数と、に基づいて、表示パネル３ａの輝度を算出する。ここで、表示パネル３ａの輝度の算出は、出力電流の決定を意味する。 Further, the process proceeds to step S311, and the display control device 10 determines whether the illuminance data serving as the reference determined in step S310 and the high-level luminance coefficient for passengers selected in step S308 or the non-passenger selected in step S309 are not used. The luminance of the display panel 3a is calculated based on the luminance coefficient of the level. Here, calculation of the luminance of the display panel 3a means determination of the output current.
　この後、ステップＳ３１２に進み、表示制御装置１０は、ステップＳ３１１で算出した輝度に応じて、表示パネル３ａの表示輝度を制御する。これにより、各表示装置３の表示照度を変更する処理が行われる。 After that, the process proceeds to step S312, and the display control device 10 controls the display brightness of the display panel 3a according to the brightness calculated in step S311. Thereby, the process of changing the display illuminance of each display device 3 is performed.
　各表示装置３の表示パネル３ａの総数個分、上述したステップＳ３０７～ステップＳ３１２の処理が繰り返し行われることにより、それぞれの表示パネル３ａに対する表示輝度が、連続的に制御される。この結果、各表示装置３の表示輝度を、乗客の移動に応じて適切に変更する制御が実現できる。 (4) The display luminance for each display panel 3a is continuously controlled by repeatedly performing the above-described processing of steps S307 to S312 for the total number of display panels 3a of each display device 3. As a result, control for appropriately changing the display brightness of each display device 3 according to the movement of the passenger can be realized.
　以上に説明した実施の形態１に係る表示制御システムでは、第１の検出センサ７及び第２の検出センサ８による検出結果と、乗客センサ１２による検出結果と、制御盤９から出力され運転転状況の情報とを表示制御装置１０で取得する。そして、表示制御装置１０は、これらの取得結果に基づいて、各表示パネル３ａを適切な表示輝度に制御することができる。 In the display control system according to the first embodiment described above, the detection result by the first detection sensor 7 and the second detection sensor 8, the detection result by the passenger sensor 12, and the driving state output from the control panel 9 Is acquired by the display control device 10. Then, the display control device 10 can control each display panel 3a to an appropriate display luminance based on the obtained results.
　この結果、表示装置３の表示輝度を無駄なく好適に制御することが可能で、表示メッセージの内容を確実に乗客に伝えることが可能になる。また、乗客が視認しない状況において、表示輝度を抑制することによって、省エネ化を図ることが可能になる。 結果 As a result, the display brightness of the display device 3 can be appropriately controlled without waste, and the contents of the display message can be transmitted to the passenger without fail. Further, in a situation where the passenger is not visually recognizable, it is possible to save energy by suppressing the display luminance.
　尚、実施の形態１に係る表示制御システムは、乗客コンベアをエスカレータ１とした場合を説明した。乗客コンベアを動く歩道とした場合にも、実施の形態１に係る表示制御システムは、同様に適用できる。動く歩道の場合、図１に示したエスカレータ１と比べ、踏段２が傾斜されておらず、平面状に展開し、それに伴い、トラス４の形状も床面に対して立設される形態となる点が相違する。表示装置３についても、図２に示すように傾斜されずに設置される形態となる。表示装置３の設置箇所は、壁面、仕切り面等である。表示制御システム自体は、エスカレータ１に適用した場合と同様な構成及び機能であるので、説明を省略する。 In the display control system according to the first embodiment, the case where the passenger conveyor is the escalator 1 has been described. The display control system according to the first embodiment can be similarly applied to a case where the passenger conveyor is a moving sidewalk. In the case of a moving sidewalk, the steps 2 are not inclined and are developed in a plane as compared with the escalator 1 shown in FIG. 1, and accordingly, the shape of the truss 4 is set up on the floor surface. The points are different. The display device 3 is also installed without being inclined as shown in FIG. The installation location of the display device 3 is a wall surface, a partition surface, or the like. The display control system itself has the same configuration and function as when applied to the escalator 1, and thus the description is omitted.
　また、実施の形態１に係る表示制御システムでは、制御盤９からの運転情報がエスカレータ１の停止中を示すとき、表示制御装置１０が停止中用の低レベルの輝度係数に基づいて算出した輝度に応じて、表示装置３の表示輝度を下げる制御とした。これに代えて、表示装置３の表示を行わず、表示装置３の表示を停止するようにしても良い。 In the display control system according to the first embodiment, when the operation information from the control panel 9 indicates that the escalator 1 is stopped, the display control device 10 calculates the luminance calculated based on the low-level luminance coefficient for the stop. In accordance with the control, the display brightness of the display device 3 is controlled to be reduced. Alternatively, the display on the display device 3 may be stopped without displaying the display device 3.
　また、実施の形態１に係る表示制御システムでは、乗客センサ１２がそれぞれの表示パネル３ａに対して個別に１つずつ設定される場合について説明した。しかしながら、乗客センサ１２の個数は、エスカレータ１の運転速度、および表示装置３が有する表示パネル３ａの数に応じて、適宜設定することが可能である。特に、上述したように、乗客センサ１２による検出結果に対して、運転方向及び運転速度を考慮することで、踏段２の移動に伴う乗客の到達位置を予測することができる。従って、このような予測結果を用いる場合には、乗客センサ１２の数を削減することが可能である。 In the display control system according to the first embodiment, the case has been described in which the passenger sensors 12 are individually set for each of the display panels 3a. However, the number of the passenger sensors 12 can be appropriately set according to the operation speed of the escalator 1 and the number of the display panels 3a included in the display device 3. In particular, as described above, by considering the driving direction and the driving speed with respect to the detection result by the passenger sensor 12, it is possible to predict the arrival position of the passenger accompanying the movement of the steps 2. Therefore, when such a prediction result is used, the number of the passenger sensors 12 can be reduced.
　また、実施の形態１に係る表示制御システムでは、照度センサ１１を設置する際に、乗客センサ１２と１対１で照度センサ１１を設置する場合について説明した。しかしながら、照度センサ１１の個数は、エスカレータ１の運転速度、表示装置３が有する表示パネル３ａの数、及び設置環境に応じて、適宜設定することが可能である。 In the display control system according to the first embodiment, the case has been described where the illuminance sensor 11 is installed one-to-one with the passenger sensor 12 when the illuminance sensor 11 is installed. However, the number of the illuminance sensors 11 can be appropriately set according to the operation speed of the escalator 1, the number of the display panels 3a included in the display device 3, and the installation environment.
