Also, the signal receiving module 13 receives a control signal from the light control device C via the bus 14, and drives the light driving means 12 by the control signal. The bus 14 may use a wired signal line, or may use wireless communication.

ライト制御装置Ｃは、ＣＰＵ（Central Processing Unit）２０、ＲＡＭ（Random Access Memory）２１Ａ及びＲＯＭ（Read Only Memory）２１Ｂからなるメモリ２１、さらには信号発信モジュール２２を有するものであって、カードリーダ２３により取得した入退出データに基づき紫外線ライト１１を点灯／消灯させる制御信号を生成する。
なお、カードリーダ２３はバス２３Ａを介してＣＰＵ２０に接続されており、ライト制御装置Ｃの構成の一部として設けられている。 The light control device C has a CPU (Central Processing Unit) 20, a memory 21 consisting of a RAM (Random Access Memory) 21A and a ROM (Read Only Memory) 21B, and a signal transmission module 22.

ＣＰＵ２０は演算制御装置であって、メモリ２１に記憶されたプログラム及びカードリーダ２３により取得した入退出データに基づき、紫外線の照射スペースに設定された部屋内に人がいるか否かを判断するとともに、当該部屋への紫外線照射時間を計算や、照射命令を下すための制御信号を出力する（この演算制御機能については、図４のフローチャートを参照して後述する）。 The CPU 20 is an arithmetic and control unit, and judges whether or not there is a person in the room set as the ultraviolet irradiation space based on the program stored in the memory 21 and the entrance/exit data acquired by the card reader 23. It calculates the ultraviolet irradiation time for the room and outputs a control signal for issuing an irradiation command (this arithmetic control function will be described later with reference to the flowchart of FIG. 4).

メモリ２１のＲＯＭ２１ＢにはＣＰＵ２０を動作させるためのプログラムが記憶される。また、メモリ２１のＲＡＭ２１Ａには、カードリーダ２３（後述する）を介して取り込まれた入退出データが順次記憶される。

そして、このカードリーダ２３では、図３に示すような入室者の氏名（符号３０Ａで示す）、滞在時間（符号３０Ｂで示す）、入退出回数（符号３０Ｃで示す）及び部屋での滞在の有無を示す入室フラグ（符号３０Ｄで示す）からなる入退出データ３０が読み取られる。 The card reader 23 is a measuring means for measuring the entry and exit of a person to a room set in the ultraviolet irradiation space, and reads the entry and exit data of a person via a magnetic card or an IC (Integrated Circuit) card as an employee ID card. Record.
In addition, although the card reader 23 is used in the measurement means of this example, the entrance/exit data may be acquired using information specific to a person such as face authentication or fingerprint authentication.
In this card reader 23, as shown in FIG. 3, the name of the occupant (indicated by reference numeral 30A), the length of stay (indicated by reference numeral 30B), the number of times of entry and exit (indicated by reference numeral 30C), and the presence or absence of stay in the room are recorded. Entry/exit data 30 consisting of an entry flag (indicated by reference numeral 30D) indicating is read.

次に、図４のフローチャートを参照してＣＰＵ２０にて実行されるプログラムの制御内容をステップＳ毎に説明する。
〔ステップＳ１〕
カードリーダ２３にて部屋の利用者のカードがスキャンされたか否かを判断し、ＹＥＳの場合に次のステップＳ２に進む。 Next, the control contents of the program executed by the CPU 20 will be described for each step S with reference to the flowchart of FIG.
[Step S1]
It is determined whether or not the card of the user of the room has been scanned by the card reader 23, and if YES, the process proceeds to the next step S2.

〔ステップＳ２〕
ステップＳ１で取得した入退出データに基づき部屋に入室があったか否かを判断し、ＹＥＳの場合にステップＳ３に進み、ＮＯの場合にステップＳ４に進む。
〔ステップＳ３〕
ステップＳ２で入室者がいると判断した場合に、図３に示すように入室者の入室フラグ３０Ｄを立てて滞在時間３０Ｂのカウントを始めた後、ステップＳ１に戻る。なお、この処理は入室者毎に行う。 [Step S2]
Based on the entrance/exit data obtained in step S1, it is determined whether or not someone has entered the room. If YES, the process proceeds to step S3, and if NO, the process proceeds to step S4.
[Step S3]
When it is determined in step S2 that there is a person entering the room, the entrance flag 30D of the person entering the room is set as shown in FIG. 3, and the counting of the staying time 30B is started. Note that this process is performed for each person entering the room.

〔ステップＳ４〕
ステップＳ２で入室者がいないと判断した場合に、図３に示す入室者の入室フラグ３０Ｄを消して滞在時間３０Ｂのカウントを停止する。
〔ステップＳ５〕
図３に示す入室者の入室フラグ３０Ｄが全て消えているか否かを判断し、ＹＥＳの場合にステップＳ６に進み、ＮＯの場合にステップＳ１に戻る。 [Step S4]
If it is determined in step S2 that there is no occupant in the room, the entry flag 30D of the occupant shown in FIG. 3 is turned off to stop counting the stay time 30B.
[Step S5]
It is determined whether or not the entrance flags 30D of the occupants shown in FIG. 3 are all turned off. If YES, the process proceeds to step S6, and if NO, the process returns to step S1.

〔ステップＳ６〕～〔ステップＳ７〕
予め設定した以下の数式１と、図３に示す入室者毎の滞在時間３０Ｂとに基づき判定スコアを算出し（ステップＳ６）、その判定スコアを基にして得た照射時間で紫外線の照射を行う（ステップＳ７）。 [Step S6] to [Step S7]
A determination score is calculated based on the preset formula 1 below and the length of stay 30B for each person entering the room shown in FIG. (Step S7).

数式１
判定スコア＝（滞在時間の合計×入室回数の合計）
÷ （入室が許可された登録人数の２乗×係数ｎの２乗） Equation 1
Judgment score = (total length of stay x total number of times of room entry)
÷ (square of registered number of people allowed to enter × square of coefficient n)

なお、上記数式１において、１０時間を超える滞在時間は全て１０時間として計算し、１０回を超える入室回数は全て１０として計算する。
例えば、登録者が３０人おり、全員が８時間出社、全員が平均５回入室、係数ｎが１０である場合には、「滞在時間の合計＝３０×８＝２４０」、「入室回数の合計＝５×３０=１５０」となる。
その結果、判定スコアは「（２４０×１５０）÷（３０２×１０２）＝０.４」と計算される。
そして、上記数式１により得た判定スコアからは、図５の「判定スコアの範囲と照射時間Тとの関係を示す判定スコアテーブル」を基にして、「１５分」という紫外線の照射時間が求められる。 In Equation 1 above, all stay times exceeding 10 hours are calculated as 10 hours, and all room entry times exceeding 10 are calculated as 10.
For example, if there are 30 registrants, all of them come to work for 8 hours, all of them enter the room 5 times on average, and the coefficient n is 10, then "total staying time = 30 x 8 = 240", "total number of times of entering the room = 5 x 30 = 150".
As a result, the judgment score is calculated as "(240×150)÷(30 2 ×10 2 )=0.4".
Then, from the judgment score obtained by the above formula 1, the UV irradiation time of "15 minutes" is obtained based on the "judgment score table showing the relationship between the judgment score range and the irradiation time Т" in FIG. be done.

〔ステップＳ８〕
カードリーダ２３で取得した入退出データに基づき、紫外線照射中に誰かが入室したか否かを判断し、ＹＥＳの場合にステップＳ９に進み、また、ＮＯの場合にステップＳ１０に進む。 [Step S8]
Based on the entrance/exit data obtained by the card reader 23, it is determined whether or not someone entered the room during the ultraviolet irradiation.

〔ステップＳ９〕
カードリーダ２３からの入退出データにより、紫外線照射中に誰かが入室したと判断した場合には、本ステップＳ９において、紫外線ライト１１の照射を停止して、照射できなかった残りの時間をＲＡＭ２１Ａに記録し、次回照射時のステップＳ６において、判定スコアより算出された照射時間に残りの照射時間を加算して照射を行わせる。
なお、本ステップＳ９で得た新たな照射時間による紫外線照射は、ステップＳ６で実行される。 [Step S9]
If it is determined that someone has entered the room during the UV irradiation from the entry/exit data from the card reader 23, the irradiation of the UV light 11 is stopped in this step S9, and the remaining time that could not be irradiated is stored in the RAM 21A. Then, in step S6 for the next irradiation, irradiation is performed by adding the remaining irradiation time to the irradiation time calculated from the determination score.
It should be noted that the ultraviolet irradiation for the new irradiation time obtained in step S9 is executed in step S6.

具体例として、ステップＳ６で取得された「１５分」という紫外線の照射時間において、１０分照射した段階で誰かが部屋に入ってきた場合には、残り照射時間の「５分」をＲＡＭ２１Ａに記憶する。
そして、入室者が５分経過後に退出した場合には、再度ステップＳ６にて照射時間を計算し直し、その時間に、先にステップＳ９で記憶した残り照射時間の「５分」を加算した上で、ステップＳ７の紫外線照射を実行する。
なお、このとき加算する照射時間は、図５に示す「判定スコアの範囲と照射時間Тとの関係表」でも示すように、最大でも１時間とする。 As a specific example, if someone enters the room after 10 minutes of UV irradiation for the UV irradiation time of "15 minutes" acquired in step S6, the remaining irradiation time of "5 minutes" is stored in the RAM 21A. do.
Then, when the person who enters the room leaves after 5 minutes have passed, the irradiation time is calculated again in step S6, and the remaining irradiation time "5 minutes" previously stored in step S9 is added to that time. Then, the ultraviolet irradiation in step S7 is executed.
It should be noted that the irradiation time to be added at this time is one hour at the maximum, as shown in the "relationship table between the judgment score range and the irradiation time T" shown in FIG.

〔ステップＳ１０〕
上記ステップＳ６，Ｓ９で算出された照射時間に紫外線照射時間が到達したか否かを判断し、ＹＥＳの場合にステップＳ１１に進み、ＮＯの場合にステップＳ８に戻る。 [Step S10]
It is determined whether or not the ultraviolet irradiation time has reached the irradiation time calculated in steps S6 and S9. If YES, the process proceeds to step S11, and if NO, the process returns to step S8.

〔ステップＳ１１〕
照射スペースとして設定された会社内の部屋に十分な紫外線が照射されたとして本フローチャートを終了する。 [Step S11]
This flow chart ends when the room in the company set as the irradiation space is irradiated with sufficient ultraviolet light.

そして、以上のような紫外線照射システム１０１では、部屋に入室した人数や滞在時間等の入退出データを加味して照射時間を算定し、その算出結果に応じて、紫外線を点灯／消灯するライト制御装置Ｃを設けることで、部屋の使用頻度に応じて滅菌度合いを調節でき、室内の紫外線照射を過不足なく行うことが可能となる。
また、上記紫外線照射システム１０１では、紫外線照射中に誰かが入室したと判断した場合に、紫外線ライト１１の照射を停止して、照射できなかった残りの時間をＲＡＭ２１Ａに記録し、次回照射時に判定スコアより算出された照射時間に残りの照射時間を加算して照射を行うようにした。これにより安全性を高めた室内の紫外線照射を実施することが可能となる。 In the ultraviolet irradiation system 101 as described above, the irradiation time is calculated in consideration of the number of people who entered the room and the entrance/exit data such as the stay time, and the light control for turning on/off the ultraviolet light according to the calculation result. By providing the apparatus C, the degree of sterilization can be adjusted according to the frequency of use of the room, and it is possible to irradiate the room with just the right amount of ultraviolet light.
Further, in the ultraviolet irradiation system 101, when it is determined that someone has entered the room during ultraviolet irradiation, the irradiation of the ultraviolet light 11 is stopped, the remaining time during which irradiation was not possible is recorded in the RAM 21A, and judgment is made at the next irradiation. Irradiation was performed by adding the remaining irradiation time to the irradiation time calculated from the score. This makes it possible to irradiate indoors with ultraviolet rays with increased safety.

なお、上記実施形態では、カードリーダ２３で取得した入退出データに基づき、紫外線照射中に誰かが入室したか否かを判断したが、これに限定されず、部屋の出入口に設置された人感センサにより人の侵入検出をしても良い。 In the above embodiment, it is determined whether or not someone has entered the room during ultraviolet irradiation based on the entrance/exit data acquired by the card reader 23. However, the present invention is not limited to this. A sensor may be used to detect human intrusion.
