　基準距離は、レベルごとに、温度計１をドア２０に設置した場合の温度計１と被検体の額との距離に基づいて設定され格納する。 The reference distance is set and stored for each level based on the distance between the thermometer 1 and the forehead of the subject when the thermometer 1 is installed on the door 20.
　図４は、温度計１をドア２０に設置した様子を示す図である。図５は、平均的な体格の被検体の温度測定位置を示す図である。図６は、小柄な体格の被検体の温度測定の位置を示す図である。 FIG. 4 is a diagram showing a state in which the thermometer 1 is installed on the door 20. FIG. 5 is a diagram showing a temperature measurement position of a subject having an average physique. FIG. 6 is a diagram showing the position of temperature measurement of a subject having a small physique.
　図４から図６に示すように、温度計１はドア２０の平面部分の被検体の額の高さに合わせて設置される。大柄な被検体を多く測定する場合には、平均的な被検体を多く測定する場合よりもより高い位置に、小柄な被検体を多く測定する場合には、より低い位置に温度計１を設置する。 As shown in FIGS. 4 to 6, the thermometer 1 is installed according to the height of the forehead of the subject on the flat surface portion of the door 20. When measuring a large number of large subjects, install the thermometer 1 at a higher position than when measuring a large number of average subjects, and when measuring a large number of small subjects, install the thermometer 1 at a lower position. do.
　平均的な体格の被検体３１の場合、腕の長さＬ１も一定の長さの範囲に収まる。従って、被検体３１がドアノブ２１を掴んだ時の温度計１と被検体３１の額との距離Ｄ１は、被検体の腕の長さＬ１に対応して一定の長さの範囲に収まる。 In the case of a subject 31 with an average physique, the arm length L1 also falls within a certain length range. Therefore, the distance D1 between the thermometer 1 and the forehead of the subject 31 when the subject 31 grips the doorknob 21 falls within a certain length range corresponding to the arm length L1 of the subject.
　小柄な体格の被検体３２の場合、腕の長さＬ２は長さＬ１よりも短い一定の長さの範囲に収まる。従って、被検体３２がドアノブ２１を掴んだ時の温度計１と被検体３２の額との距離Ｄ２は、被検体の腕の長さＬ２に対応して一定の長さの範囲に収まる。 In the case of the subject 32 having a small physique, the arm length L2 falls within a certain length range shorter than the length L1. Therefore, the distance D2 between the thermometer 1 and the forehead of the subject 32 when the subject 32 grips the doorknob 21 falls within a certain length range corresponding to the arm length L2 of the subject.
　この各長さの中央値又は平均値をレベル距離テーブル１０２Ａの基準距離に格納する。 The median or average value of each length is stored in the reference distance of the level distance table 102A.
　図７は、温度計１の制御部１０１の動作を示すフローチャートである。図７に示すように、ステップ７０１において、制御部１０１は距離を設定する。制御部１０１は温度計１の本体に別途設けられるレベル選択部１０７であるレベルスイッチによって選択されたレベルに基づいてレベル距離テーブル１０２Ａから基準距離を読み出し、読みだした基準距離を、温度検知部１０４が検知した温度を補正するための補正用距離として設定する。 FIG. 7 is a flowchart showing the operation of the control unit 101 of the thermometer 1. As shown in FIG. 7, in step 701, the control unit 101 sets the distance. The control unit 101 reads a reference distance from the level distance table 102A based on the level selected by the level switch which is a level selection unit 107 separately provided in the main body of the thermometer 1, and reads out the reference distance to the temperature detection unit 104. It is set as a correction distance for correcting the temperature detected by.
　ステップ７０２において、制御部１０１は、制御部１０１を節電状態であるスリープ状態から起動状態に移行させる。また、制御部１０１は、発光部１０５を正常動作中であることを示す発光パターン、例えば一定間隔ごとに青色により発光させる。 In step 702, the control unit 101 shifts the control unit 101 from the sleep state, which is a power saving state, to the wake-up state. Further, the control unit 101 causes the light emitting unit 105 to emit light in a light emitting pattern indicating that the light emitting unit 105 is operating normally, for example, in blue at regular intervals.
　ステップ７０３において、制御部１０１は、温度検知部１０４によって温度測定を行う。 In step 703, the control unit 101 measures the temperature by the temperature detection unit 104.
　ステップ７０４において、制御部１０１は温度計１の前に人がいるか否かを判定する。制御部１０１は、温度検知部１０４の検知温度が第２の閾値以上、例えば３５℃以上である場合、人を検知したと判定して（ステップ７０４のＹ）ステップ７０５に進む。制御部１０１は、温度検知部１０４の検知温度が第２の閾値未満の場合、人を検知していないと判定して（ステップ７０５のＮ）ステップ７１０に進む。 In step 704, the control unit 101 determines whether or not there is a person in front of the thermometer 1. When the detection temperature of the temperature detection unit 104 is equal to or higher than the second threshold value, for example, 35 ° C. or higher, the control unit 101 determines that a person has been detected (Y in step 704) and proceeds to step 705. When the detection temperature of the temperature detection unit 104 is less than the second threshold value, the control unit 101 determines that no person has been detected (N in step 705) and proceeds to step 710.
　ステップ７０５において、制御部１０１は、温度検知部１０４によって温度測定を行う。 In step 705, the control unit 101 measures the temperature by the temperature detection unit 104.
　ステップ７０６において、制御部１０１は、気温検知部１０３によって外気温の測定を行う。 In step 706, the control unit 101 measures the outside air temperature by the air temperature detection unit 103.
　ステップ７０７において、制御部１０１は、温度補正を行う。被検体の額の温度は外気温によって被検体の内部体温より上下する。また、被検体の額から放射される赤外線の強さは、距離に応じて減衰する。 In step 707, the control unit 101 corrects the temperature. The temperature of the forehead of the subject rises and falls above the internal body temperature of the subject depending on the outside air temperature. In addition, the intensity of infrared rays emitted from the forehead of the subject is attenuated according to the distance.
　従って、制御部１０１は、気温検知部１０３によって検知された外気温と、設定されたレベルに対応する距離（補正用距離）に基づいて、予め定められた数式又は換算表によって温度検知部１０４が検知した被検体の額の温度を補正して推定体温を算出する。 Therefore, in the control unit 101, the temperature detection unit 104 uses a predetermined mathematical formula or conversion table based on the outside air temperature detected by the temperature detection unit 103 and the distance (correction distance) corresponding to the set level. The estimated body temperature is calculated by correcting the temperature of the detected forehead of the subject.
　ステップ７０８において、制御部１０１は、推定体温が第１の閾値を超えているか判定する。第１の閾値は、例えば３７．５℃など、感染症に罹患したと疑われる体温に設定できる。制御部１０１は、推定体温が第１の閾値を超えていると判定した場合（ステップ７０８のＹ）ステップ７０９に進み、推定体温が第１の閾値以下であると判定した場合（ステップ７０８のＮ）、発光部１０５をその旨を示す発光パターン、例えば一定時間の間青色により発光させ、ステップ７０２に戻る。 In step 708, the control unit 101 determines whether the estimated body temperature exceeds the first threshold value. The first threshold can be set to a body temperature suspected of having an infectious disease, for example 37.5 ° C. When the control unit 101 determines that the estimated body temperature exceeds the first threshold value (Y in step 708), the control unit 101 proceeds to step 709, and when it determines that the estimated body temperature is equal to or lower than the first threshold value (N in step 708). ), The light emitting unit 105 is made to emit light with a light emitting pattern indicating that effect, for example, blue for a certain period of time, and the process returns to step 702.
　ステップ７０９において、制御部１０１は警報を発報する。制御部１０１は、警報として、発光部１０５を推定体温が第１の閾値を超えたことを示す発光パターン、例えば赤色により連続して発行させ、発声部１０６から警告音を発生させる。 In step 709, the control unit 101 issues an alarm. As an alarm, the control unit 101 continuously issues a light emitting unit 105 with a light emitting pattern indicating that the estimated body temperature exceeds the first threshold value, for example, red, and generates a warning sound from the vocalizing unit 106.
　ステップ７１０において、制御部１０１は、所定時間経過したか判定する。制御部１０１は、所定時間経過したと判定した場合（ステップ７１０のＹ）ステップ７１１に進み、所定時間経過していないと判定した場合（ステップ７１０のＮ）ステップ７０３に戻る。 In step 710, the control unit 101 determines whether a predetermined time has elapsed. The control unit 101 proceeds to step 711 when it is determined that the predetermined time has elapsed (Y in step 710), and returns to step 703 when it is determined that the predetermined time has not elapsed (N in step 710).
　ステップ７１１において、制御部１０１は節電状態であるスリープ状態に移行する。 In step 711, the control unit 101 shifts to the sleep state, which is a power saving state.
　ステップ７１２において、制御部１０１は、所定時間経過したか判定する。制御部１０１は、所定時間経過したと判定した場合（ステップ７１２のＹ）ステップ７０２に戻り、所定時間経過していないと判定した場合（ステップ７１２のＮ）ステップ７１２に戻る。 In step 712, the control unit 101 determines whether a predetermined time has elapsed. The control unit 101 returns to step 702 when it is determined that the predetermined time has elapsed (Y in step 712), and returns to step 712 when it is determined that the predetermined time has not elapsed (N in step 712).
　つまり、制御部１０１はスリープ状態と起動状態とを繰り返しながら節電する。 That is, the control unit 101 saves power while repeating the sleep state and the wake-up state.
