Based on the control, the drive of the second sensor unit is controlled. Therefore, even if the temperature tolerance of the first sensor unit is low, the reliability of the control of the drive control unit can be enhanced.

　以下、この発明の空気調和機を図示の実施の形態により詳細に説明する。なお、図面において、同一の参照番号は、同一部分または相当部分を表わすものである。 Hereinafter, the air conditioner of the present invention will be described in detail by the illustrated embodiment. In the drawings, the same reference numerals represent the same or corresponding parts.
　図１は、この発明の一実施形態の空気調和機の室内ユニット１のケーシング２の設置状態を示す概略図である。 FIG. 1 is a schematic view showing an installation state of a casing 2 of an indoor unit 1 of an air conditioner according to an embodiment of the present invention.
　上記空気調和機は、室内ユニット１のケーシング２と、この室内ユニット１のケーシング２と冷媒配管などを介して接続された室外ユニット(図示せず)とを備えている。 The air conditioner includes a casing 2 of the indoor unit 1 and an outdoor unit (not shown) connected to the casing 2 of the indoor unit 1 via a refrigerant pipe or the like.
　室内ユニット１のケーシング２は、室内の壁面１０１の上側に設置されている。壁面１０１には、室内ユニット１のケーシング２の近傍にコンセント１０２が設けられている。室内ユニット１のケーシング２が電源ケーブル１０を介してコンセント１０２に接続されている。また、室内ユニット１のケーシング２には焦電型赤外線センサ３および室温センサ４が固定されている。この焦電型赤外線センサ３は、人体からの赤外線を受光できるように、少なくとも一部が室内ユニット１のケーシング２から露出している。一方、室温センサ４は、室内空気の温度を検出するため、室内ユニット１のケーシング２内の吸込口２ａの近傍に設置されている。なお、焦電型赤外線センサ３は第１センサ部の一例である。 The casing 2 of the indoor unit 1 is installed above the wall surface 101 of the room. An outlet 102 is provided on the wall surface 101 near the casing 2 of the indoor unit 1. A casing 2 of the indoor unit 1 is connected to an outlet 102 via a power cable 10. Further, a pyroelectric infrared sensor 3 and a room temperature sensor 4 are fixed to the casing 2 of the indoor unit 1. At least a part of the pyroelectric infrared sensor 3 is exposed from the casing 2 of the indoor unit 1 so as to be able to receive infrared light from the human body. On the other hand, the room temperature sensor 4 is installed in the vicinity of the suction port 2 a in the casing 2 of the indoor unit 1 in order to detect the temperature of the indoor air. The pyroelectric infrared sensor 3 is an example of a first sensor unit.
　また、室内ユニット１のケーシング２の下側右側部には、第２センサ部の一例としての可動センサ部５が回動可能に取り付けられている。この可動センサ部５は、円柱形状のケーシング５０と、レーダーの一例としてのドップラーセンサ５１と、サーモパイル型赤外線センサ５２と、画像センサの一例としての距離画像センサ５３とを有している。ここで、ドップラーセンサ５１はケーシング５０で覆われて一部も露出していないが、サーモパイル型赤外線センサ５２および距離画像センサ５３は、それぞれ、受光部がケーシング５０から露出している。 A movable sensor unit 5 as an example of a second sensor unit is rotatably attached to the lower right side of the casing 2 of the indoor unit 1. The movable sensor unit 5 has a cylindrical casing 50, a Doppler sensor 51 as an example of a radar, a thermopile infrared sensor 52, and a distance image sensor 53 as an example of an image sensor. Here, although the Doppler sensor 51 is covered with the casing 50 and a part thereof is not exposed, the light receiving portion of each of the thermopile infrared sensor 52 and the distance image sensor 53 is exposed from the casing 50.
　図２は、焦電型赤外線センサ３の検出範囲Ｅ０を説明するための模式図である。また、図３は、ドップラーセンサ５１の検出範囲Ｅ１を説明するための模式図である。また、図４は、サーモパイル型赤外線センサ５２の検出範囲Ｅ２を説明するための模式図である。また、図５は、距離画像センサ５３の検出範囲Ｅ３を説明するための模式図である。 FIG. 2 is a schematic view for explaining the detection range E0 of the pyroelectric infrared sensor 3. As shown in FIG. FIG. 3 is a schematic view for explaining a detection range E1 of the Doppler sensor 51. FIG. 4 is a schematic view for explaining a detection range E2 of the thermopile type infrared sensor 52. Moreover, FIG. 5 is a schematic diagram for demonstrating the detection range E3 of the distance image sensor 53. As shown in FIG.
　図２～図５に示すように、焦電型赤外線センサ３の水平方向の検出範囲Ｅ０は、ドップラーセンサ５１，サーモパイル型赤外線センサ５２，距離画像センサ５３の水平方向の検出範囲Ｅ３よりも広くなっている。より詳しく説明すると、距離画像センサ５３の水平方向の検出範囲Ｅ３は、サーモパイル型赤外線センサ５２の水平方向の検出範囲Ｅ２よりも広くなっている。また、サーモパイル型赤外線センサ５２の水平方向の検出範囲Ｅ２は、ドップラーセンサ５１の水平方向の検出範囲Ｅ１よりも広くなっている。すなわち、ドップラーセンサ５１，サーモパイル型赤外線センサ５２および距離画像センサ５３においては、ドップラーセンサ５１の水平方向の検出範囲Ｅ１が最も狭く、距離画像センサ５３の水平方向の検出範囲Ｅ３が最も広くなっている。ここで、検出範囲Ｅ０～Ｅ１とは、各センサで人体に関する情報を検出可能な領域を指す。なお、焦電型赤外線センサ３の水平方向の検出範囲Ｅ０は、第１範囲の一例である。また、ドップラーセンサ５１，サーモパイル型赤外線センサ５２および距離画像センサ５３の水平方向の検出範囲Ｅ３は、第２範囲の一例である。 As shown in FIGS. 2 to 5, the detection range E0 in the horizontal direction of the pyroelectric infrared sensor 3 is wider than the detection range E3 in the horizontal direction of the Doppler sensor 51, the thermopile infrared sensor 52, and the distance image sensor 53. ing. More specifically, the horizontal detection range E3 of the distance image sensor 53 is wider than the horizontal detection range E2 of the thermopile infrared sensor 52. Further, the detection range E2 in the horizontal direction of the thermopile infrared sensor 52 is wider than the detection range E1 in the horizontal direction of the Doppler sensor 51. That is, in the Doppler sensor 51, the thermopile infrared sensor 52, and the distance image sensor 53, the detection range E1 in the horizontal direction of the Doppler sensor 51 is the narrowest, and the detection range E3 in the horizontal direction of the distance image sensor 53 is the widest. . Here, the detection ranges E0 to E1 indicate areas in which information on the human body can be detected by each sensor. The detection range E0 in the horizontal direction of the pyroelectric infrared sensor 3 is an example of a first range. A detection range E3 in the horizontal direction of the Doppler sensor 51, the thermopile infrared sensor 52, and the distance image sensor 53 is an example of a second range.
　また、焦電型赤外線センサ３およびドップラーセンサ５１の検出距離は、サーモパイル型赤外線センサ５２および距離画像センサ５３の検出距離よりも長くなっている。そして、焦電型赤外線センサ３の検出距離は、ドップラーセンサ５１の検出距離と略同じである。また、サーモパイル型赤外線センサ５２の検出距離は、距離画像センサ５３の検出距離と略同じである。すなわち、焦電型赤外線センサ３およびドップラーセンサ５１の検出距離は比較的長く、サーモパイル型赤外線センサ５２および距離画像センサ５３の検出距離は比較的短くなっている。 Further, the detection distances of the pyroelectric infrared sensor 3 and the Doppler sensor 51 are longer than the detection distances of the thermopile infrared sensor 52 and the distance image sensor 53. The detection distance of the pyroelectric infrared sensor 3 is substantially the same as the detection distance of the Doppler sensor 51. Further, the detection distance of the thermopile infrared sensor 52 is substantially the same as the detection distance of the distance image sensor 53. That is, the detection distances of the pyroelectric infrared sensor 3 and the Doppler sensor 51 are relatively long, and the detection distances of the thermopile infrared sensor 52 and the distance image sensor 53 are relatively short.
　図６は、上記空気調和機の要部のブロック図である。 FIG. 6 is a block diagram of the main part of the air conditioner.
　室内ユニット１のケーシング２は、マイクロコンピュータと入出力回路などからなる制御装置６と、可動センサ部５を駆動する駆動装置７とを備えている。この制御装置６は、焦電型赤外線センサ３,室温センサ４,ドップラーセンサ５１,サーモパイル型赤外線センサ５２,距離画像センサ５３,駆動装置７などに接続されており、各センサからの信号を受信する。また、制御装置６は、焦電型赤外線センサ３,ドップラーセンサ５１,サーモパイル型赤外線センサ５２および距離画像センサ５３の少なくとも一つによって検出される情報に基づいて、室内ユニット１のケーシング２の空調運転を制御する。 The casing 2 of the indoor unit 1 includes a control device 6 including a microcomputer and an input / output circuit, and a drive device 7 for driving the movable sensor unit 5. The control device 6 is connected to the pyroelectric infrared sensor 3, the room temperature sensor 4, the Doppler sensor 51, the thermopile infrared sensor 52, the distance image sensor 53, the driving device 7 and the like, and receives signals from the respective sensors. . Further, the control device 6 performs the air conditioning operation of the casing 2 of the indoor unit 1 based on the information detected by at least one of the pyroelectric infrared sensor 3, the Doppler sensor 51, the thermopile infrared sensor 52 and the distance image sensor 53. Control.
　焦電型赤外線センサ３は、強誘電体を有し、人体からの赤外線を受光する。このとき、上記赤外線の受光量に応じた変化が強誘電体の自発分極に生じ、強誘電体の表面の電荷が増減する。この強誘電体の表面の電荷量を示す信号が制御装置６で処理されることにより、室内に居る人の体動に関する情報が検出される。なお、室内に居る人の体動に関する情報は、第１情報の一例である。 The pyroelectric infrared sensor 3 has a ferroelectric substance and receives infrared rays from the human body. At this time, a change according to the amount of light received by the infrared light occurs in the spontaneous polarization of the ferroelectric, and the charge on the surface of the ferroelectric increases or decreases. The signal indicating the amount of charge on the surface of the ferroelectric is processed by the control device 6 to detect information on the body movement of the person in the room. In addition, the information regarding the body motion of the person who is indoors is an example of 1st information.
　室温センサ４は、サーミスタからなり、室内空気の温度に応じて抵抗値が変化する。制御装置６は、この室温センサ４の抵抗値を示す信号に基づいて、室内空気の温度を検出する。 The room temperature sensor 4 is composed of a thermistor, and its resistance value changes according to the temperature of room air. The control device 6 detects the temperature of the room air based on the signal indicating the resistance value of the room temperature sensor 4.
　ドップラーセンサ５１は、例えばＦＭ－ＣＷ(Frequency Modulated Continuous Wave)方式のドップラーレーダーであり、周波数変調されたマイクロ波を人体に出射する。このとき、人体とドップラーセンサ５１との距離が変化すると、ドップラー効果によって人体で反射した反射波が変化する。この人体からの反射波を示す信号が制御装置６で処理されることにより、室内に居る人の脈拍および呼吸に関する情報と、上記人の数に関する情報とが、検出される。なお、室内に居る人の脈拍および呼吸に関する情報と、上記人の数に関する情報とは、第２情報の一例である。 The Doppler sensor 51 is, for example, an FM-CW (Frequency Modulated Continuous Wave) Doppler radar, and emits a frequency-modulated microwave to a human body. At this time, when the distance between the human body and the Doppler sensor 51 changes, the reflected wave reflected by the human body changes due to the Doppler effect. The signal indicating the reflected wave from the human body is processed by the control device 6, whereby information on the pulse and respiration of the person in the room and information on the number of the persons are detected. The information on the pulse and respiration of the person in the room and the information on the number of persons are examples of the second information.
　サーモパイル型赤外線センサ５２は、人体からの赤外線を受光すると、赤外線の受光量に応じた起電力が発生する。この起電力を示す信号が制御装置６で処理されることにより、室内に居る人の皮膚温に関する情報が検出される。なお、室内に居る人の皮膚温に関する情報は、第２情報の一例である。 When the thermopile infrared sensor 52 receives infrared light from the human body, an electromotive force corresponding to the amount of received infrared light is generated. The signal indicating the electromotive force is processed by the control device 6 to detect information on the skin temperature of the person in the room. In addition, the information regarding the skin temperature of the person who is indoors is an example of 2nd information.
　距離画像センサ５３は、例えばＴＯＦ(Time Of Flight)方式距離画像センサである。より詳しく説明すると、距離画像センサ５３は、人体に向けてレーザ光を出射し、人体で反射されたレーザ光を受光する。この人体で反射されたレーザ光を示す信号が制御装置６で処理されることにより、室内に居る人との距離に関する情報と、その人の行動および姿勢に関する情報とが、検出される。なお、室内に居る人との距離に関する情報と、その人の行動および姿勢に関する情報とは、第２情報の一例である。 The distance image sensor 53 is, for example, a TOF (Time Of Flight) distance image sensor. More specifically, the distance image sensor 53 emits laser light toward the human body and receives laser light reflected by the human body. The signal indicating the laser beam reflected by the human body is processed by the control device 6 to detect information on the distance to the person in the room and information on the action and posture of the person. The information on the distance to the person in the room and the information on the action and posture of the person are examples of the second information.
　また、制御装置６は、室内温度判定部６１と、駆動制御部６２とを有している。この室内温度判定部６１および駆動制御部６２は、それぞれ、ソフトウェアで構成されている。 Further, the control device 6 includes an indoor temperature determination unit 61 and a drive control unit 62. The indoor temperature determination unit 61 and the drive control unit 62 are each configured by software.
　室内温度判定部６１は、室温センサ４により検出された室内温度が、予め定めた温度以上であるか否かを判定する。ここで、上記予め定めた温度は、焦電型赤外線センサ３の耐熱性に応じて設定される。これにより、上記予め定めた温度未満であれば、焦電型赤外線センサ３による情報の検出が不可能または不正確とならない一方、上記予め定めた温度以上であれば、焦電型赤外線センサ３による情報の検出が不可能または不正確となる。 The indoor temperature determination unit 61 determines whether the indoor temperature detected by the room temperature sensor 4 is equal to or higher than a predetermined temperature. Here, the predetermined temperature is set according to the heat resistance of the pyroelectric infrared sensor 3. Thus, if the temperature is lower than the predetermined temperature, detection of information by the pyroelectric infrared sensor 3 is not impossible or inaccurate, while if it is higher than the predetermined temperature, the pyroelectric infrared sensor 3 Detection of information becomes impossible or inaccurate.
　駆動制御部６２は、室温センサ４により検出された室内温度が、予め定めた温度以上でないと判定されたとき、焦電型赤外線センサ３によって検出された情報(室内に居る人の体動に関する情報)に基づいて、可動センサ部５の駆動を制御する。一方、駆動制御部６２は、室温センサ４により検出された室内温度が、予め定めた温度以上であると判定されたとき、予め定めた駆動条件に基づいて、可動センサ部５の駆動を制御する。より詳しく説明すると、予め定めた回動角だけ可動センサ部５が回動するように、可動センサ部５の駆動が制御される。この可動センサ部５の回動は、ドップラーセンサ５１，サーモパイル型赤外線センサ５２および距離画像センサ５３のうちの少なくとも一つにより情報が検出されるまで繰り返される。なお、上記情報の検出の繰り返しは、予め定めた時間が経過しても、ドップラーセンサ５１，サーモパイル型赤外線センサ５２および距離画像センサ５３の少なくとも一つにより情報が検出されないとき、終了するようにしてもよい。 When it is determined that the room temperature detected by the room temperature sensor 4 is not higher than a predetermined temperature, the drive control unit 62 detects information detected by the pyroelectric infrared sensor 3 (information related to the body movement of a person in the room The drive of the movable sensor unit 5 is controlled based on. On the other hand, when it is determined that the indoor temperature detected by the room temperature sensor 4 is equal to or higher than a predetermined temperature, the drive control unit 62 controls the driving of the movable sensor unit 5 based on the predetermined drive condition. . More specifically, the drive of the movable sensor unit 5 is controlled such that the movable sensor unit 5 is rotated by a predetermined rotation angle. The rotation of the movable sensor unit 5 is repeated until information is detected by at least one of the Doppler sensor 51, the thermopile infrared sensor 52, and the distance image sensor 53. In addition, the repetition of the detection of the above information is ended so that the information is not detected by at least one of the Doppler sensor 51, the thermopile infrared sensor 52, and the distance image sensor 53 even after a predetermined time has elapsed. It is also good.
　また、駆動装置７は、例えばステッピングモータからなり、可動センサ部５のケーシング５０に直接またはギヤを介して駆動力を与える。 The driving device 7 is, for example, a stepping motor, and applies a driving force to the casing 50 of the movable sensor unit 5 directly or through a gear.
　下表１は、焦電型赤外線センサ３,ドップラーセンサ５１,サーモパイル型赤外線センサ５２,距離画像センサ５３の特性を説明するための表である。 Table 1 below is a table for explaining the characteristics of the pyroelectric infrared sensor 3, the Doppler sensor 51, the thermopile infrared sensor 52, and the distance image sensor 53.
Figure JPOXMLDOC01-appb-T000001
Figure JPOXMLDOC01-appb-T000001
　上記表１に示しているように、焦電型赤外線センサ３,室温センサ４,ドップラーセンサ５１,サーモパイル型赤外線センサ５２,距離画像センサ５３によって、上述した情報以外の情報も検出可能である。例えば、ドップラーセンサ５１からの信号を制御装置６で処理することにより、室内に居る人の体動に関する情報、上記人との距離に関する情報、および、上記人の姿勢に関する情報も、検出可能である。 As shown in Table 1, the pyroelectric infrared sensor 3, the room temperature sensor 4, the Doppler sensor 51, the thermopile infrared sensor 52, and the distance image sensor 53 can also detect information other than the above-described information. For example, when the signal from the Doppler sensor 51 is processed by the control device 6, it is possible to detect information on body movement of a person in the room, information on the distance to the person, and information on the posture of the person .
　また、各センサにより情報を検出できない環境がある。より具体的に言うと、室内が暗闇になっている環境だと、距離画像センサ５３により情報を検出できない。また、室内が高温環境だと、焦電型赤外線センサ３およびサーモパイル型赤外線センサ５２により情報を検出できない。また、振動が生じている環境では、ドップラーセンサ５１により情報を検出できない。 Moreover, there is an environment where information can not be detected by each sensor. More specifically, in an environment where the room is dark, the distance image sensor 53 can not detect information. In addition, when the room is in a high temperature environment, information can not be detected by the pyroelectric infrared sensor 3 and the thermopile infrared sensor 52. In addition, in an environment where vibration occurs, the information can not be detected by the Doppler sensor 51.
　また、上記表１で示していないが、距離画像センサ５３を用いることにより、室内に居る人の識別情報も得られる。すなわち、距離画像センサ５３からの信号を制御装置６で処理することにより、個人認証を行うことも可能である。 Further, although not shown in the above-mentioned Table 1, by using the distance image sensor 53, identification information of a person present in the room can also be obtained. That is, it is also possible to perform personal authentication by processing the signal from the distance image sensor 53 by the control device 6.
　なお、上記表１において、△は、○に比べて、情報の検出の精度が低いことを意味している。また、×は、情報の検出ができないことを意味している。 In Table 1, Δ means that the accuracy of detection of information is lower than ○. Also, x means that information can not be detected.
　上記構成の空気調和機では、焦電型赤外線センサ３,ドップラーセンサ５１,サーモパイル型赤外線センサ５２および距離画像センサ５３の水平方向の検出範囲Ｅ０～Ｅ３内に人が入っている場合、焦電型赤外線センサ３,ドップラーセンサ５１,サーモパイル型赤外線センサ５２および距離画像センサ５３による検出された情報に基づいて、室内ユニット１の空調運転が制御される。したがって、上記室内に居る人と室内ユニット１の空調運転との適合性を高めることができる。 In the air conditioner of the above configuration, when a person is in the horizontal detection range E0 to E3 of the pyroelectric infrared sensor 3, the Doppler sensor 51, the thermopile infrared sensor 52, and the distance image sensor 53, a pyroelectric type The air conditioning operation of the indoor unit 1 is controlled based on the information detected by the infrared sensor 3, the Doppler sensor 51, the thermopile type infrared sensor 52 and the distance image sensor 53. Therefore, the compatibility between the person present in the room and the air conditioning operation of the indoor unit 1 can be enhanced.
　また、室内に居る人が、焦電型赤外線センサ３の水平方向の検出範囲Ｅ０内に入っているが、例えばドップラーセンサ５１の水平方向の検出範囲Ｅ１内に入っていない場合、可動センサ部５をケーシング５０の中心軸を中心に回動させて、その検出範囲Ｅ１内に人を入れることができる。したがって、ドップラーセンサ５１による情報の検出能力を高めることができる。 Further, when the person in the room is within the detection range E0 of the pyroelectric infrared sensor 3 in the horizontal direction, for example, when it is not within the detection range E1 of the Doppler sensor 51 in the horizontal direction, the movable sensor unit 5 Can be turned about the central axis of the casing 50 to put a person in the detection range E1. Therefore, the detection capability of information by the Doppler sensor 51 can be enhanced.
　また、上記室内に居る人が、焦電型赤外線センサ３の水平方向の検出範囲Ｅ０内に入っているが、サーモパイル型赤外線センサ５２，距離画像センサ５３の水平方向の検出範囲Ｅ２，Ｅ３内に入っていない場合も、可動センサ部５をケーシング５０の中心軸を中心に回動させて、その検出範囲Ｅ２，Ｅ３内に人を入れることができる。 Further, although the person in the room is within the detection range E0 of the pyroelectric infrared sensor 3 in the horizontal direction, it is within the detection ranges E2, E3 of the thermopile infrared sensor 52 and the distance image sensor 53 in the horizontal direction. Even when it does not enter, the movable sensor unit 5 can be rotated about the central axis of the casing 50 to put a person in the detection range E2, E3.
　また、室内ユニット１のケーシング２がリビングルームに設置されている場合、室内に居る人の体動に関する情報を焦電型赤外線センサ３で検出した後、その情報に基づいて、距離画像センサ５３の水平方向の検出範囲Ｅ３内に人が入るように、可動センサ部５を駆動させてもよい。このようにすると、距離画像センサ５３で情報を検出するのに要するのにかかる時間を短くすることができる。 In addition, when the casing 2 of the indoor unit 1 is installed in the living room, after the information related to the body movement of the person in the room is detected by the pyroelectric infrared sensor 3, the distance image sensor 53 is The movable sensor unit 5 may be driven so that a person falls within the horizontal detection range E3. In this way, it is possible to shorten the time required for the distance image sensor 53 to detect information.
　また、室内ユニット１のケーシング２がベッドルームに設置されている場合、室内に居る人の体動に関する情報を焦電型赤外線センサ３で検出した後、その情報に基づいて、ドップラーセンサ５１またはサーモパイル型赤外線センサ５２の水平方向の検出範囲Ｅ２内に人が入るように、可動センサ部５を駆動させてもよい。このようにすると、ドップラーセンサ５１またはサーモパイル型赤外線センサ５２で情報を検出するのに有する時間を短くすることができる。 In addition, when the casing 2 of the indoor unit 1 is installed in the bedroom, after the information related to the body movement of the person in the room is detected by the pyroelectric infrared sensor 3, the Doppler sensor 51 or the thermopile is based on the information. The movable sensor unit 5 may be driven so that a person falls within the horizontal detection range E2 of the infrared sensor 52. In this way, it is possible to shorten the time which the Doppler sensor 51 or the thermopile infrared sensor 52 has to detect information.
　このように、焦電型赤外線センサ３により検出された情報を用いて、可動センサ部５の駆動を制御することは、有益だが、室内が高温環境だと、焦電型赤外線センサ３により情報を検出できなくなってしまう。 As described above, it is useful to control the drive of the movable sensor unit 5 using the information detected by the pyroelectric infrared sensor 3, but if the room is in a high temperature environment, the pyroelectric infrared sensor 3 may use the information It can not be detected.
　そこで、室温センサ４により検出された室内温度が、予め定めた温度以上でないと判定されたとき、駆動制御部６２は、焦電型赤外線センサ３により検出された情報に基づいて、可動センサ部５の駆動を制御する。一方、室温センサ４により検出された室内温度が、予め定めた温度以上であると判定されたとき、駆動制御部６２は、予め定めた駆動条件に基づいて、可動センサ部５の駆動を制御する。その結果、室内の温度に関係なく、ドップラーセンサ５１,サーモパイル型赤外線センサ５２および距離画像センサ５３の水平方向の検出範囲Ｅ１～Ｅ３内に人を入れることができる。したがって、駆動制御部６２の制御の信頼性を高めることができる。 Therefore, when it is determined that the room temperature detected by the room temperature sensor 4 is not equal to or higher than a predetermined temperature, the drive control unit 62 controls the movable sensor unit 5 based on the information detected by the pyroelectric infrared sensor 3. Control the driving of On the other hand, when it is determined that the room temperature detected by the room temperature sensor 4 is equal to or higher than the predetermined temperature, the drive control unit 62 controls the driving of the movable sensor unit 5 based on the predetermined driving conditions. . As a result, it is possible to put a person in the horizontal detection range E1 to E3 of the Doppler sensor 51, the thermopile type infrared sensor 52 and the distance image sensor 53 regardless of the indoor temperature.
