A block diagram of the sensor device of this embodiment is shown in FIG. The sensor device includes a control unit 1, an infrared sensor unit 2, an illuminance sensor unit 3, a temperature sensor unit 4, a humidity sensor unit 5, an antenna 6, a wireless communication unit 7, a power supply unit 8, and the like.

赤外線センサ部２は、多数のサーモパイル素子が縦横に配置されてなる赤外線アレイセンサ(図示せず)や、赤外線アレイセンサから出力される電気信号を信号処理して検出領域の温度分布を求める信号処理回路(図示せず)などを具備する。赤外線アレイセンサは、検出領域に存在する熱源(例えば、人体)から放射される赤外線を各サーモパイル素子で検出する。信号処理回路は、各サーモパイル素子で検出される赤外線量を温度値に変換するとともに各サーモパイル素子の温度値をその位置座標と対応付けたもの(以下、熱画像と呼ぶ。)を一定のフレーム周期で外部(制御部１)に出力する。   The infrared sensor unit 2 is an infrared array sensor (not shown) in which a number of thermopile elements are arranged vertically and horizontally, or a signal process for obtaining a temperature distribution in a detection region by processing an electric signal output from the infrared array sensor. A circuit (not shown) is provided. The infrared array sensor detects infrared rays emitted from a heat source (for example, a human body) existing in a detection region by each thermopile element. The signal processing circuit converts the amount of infrared rays detected by each thermopile element into a temperature value and associates the temperature value of each thermopile element with its position coordinate (hereinafter referred to as a thermal image) at a fixed frame period. To the outside (control unit 1).

照度センサ部３は、光電変換素子と、光電変換素子の出力電流(光電流)の大きさに応じた電圧信号(照度信号)を出力する出力回路とを有する。温度センサ部４は、サーミスタなどの温度検出素子を用いて検出領域における雰囲気温度を検出し、当該雰囲気温度に応じた温度検出信号を外部(制御部１)に出力する。湿度センサ部５は、検出素子の電気抵抗又は静電容量の変化を利用して検出領域における湿度を検出し、当該湿度に応じた湿度検出信号を外部(制御部１)に出力する。   The illuminance sensor unit 3 includes a photoelectric conversion element and an output circuit that outputs a voltage signal (illuminance signal) corresponding to the magnitude of the output current (photocurrent) of the photoelectric conversion element. The temperature sensor unit 4 detects the ambient temperature in the detection region using a temperature detection element such as a thermistor, and outputs a temperature detection signal corresponding to the ambient temperature to the outside (the control unit 1). The humidity sensor unit 5 detects the humidity in the detection region using a change in the electrical resistance or capacitance of the detection element, and outputs a humidity detection signal corresponding to the humidity to the outside (the control unit 1).

制御部１はマイクロコントローラからなり、各センサ部２〜５の検出出力を信号処理する。例えば、制御部１では、赤外線センサ部２からフレーム周期毎に出力される熱画像に基づき、検出領域における人の存在や人数、さらに各人の移動方向などを検出し、その検出結果を示す情報(人体検出情報)を無線通信部７に出力する。同様に、制御部１は照度センサ部３、温度センサ部４、湿度センサ部５から出力される照度信号、温度検出信号、湿度検出信号に基づき、検出領域における照度、温度、湿度の各検出結果を示す情報(照度情報、温度情報、湿度情報)を電気信号として無線通信部７に出力する。   The control unit 1 includes a microcontroller, and performs signal processing on detection outputs of the sensor units 2 to 5. For example, the control unit 1 detects the presence and number of people in the detection area, and the movement direction of each person based on the thermal image output from the infrared sensor unit 2 for each frame period, and information indicating the detection result (Human body detection information) is output to the wireless communication unit 7. Similarly, the control unit 1 detects each illuminance, temperature, and humidity detection result in the detection area based on the illuminance signal, temperature detection signal, and humidity detection signal output from the illuminance sensor unit 3, the temperature sensor unit 4, and the humidity sensor unit 5. (Illuminance information, temperature information, humidity information) indicating the above is output to the wireless communication unit 7 as an electrical signal.

無線通信部７は、制御部１から入力される電気信号(人体検出情報、照度情報、温度情報、湿度情報)を無線通信媒体(電波)を利用し、アンテナ６を介して外部に出力(送信)する。すなわち、本実施形態では制御部１とアンテナ６と無線通信部７が出力部に相当する。ただし、アンテナ６及び無線通信部７に代えて、通信ケーブルを介して電気信号を伝送する有線の通信インターフェース(例えば、ＵＳＢインターフェース)を出力部に採用しても構わない。   The wireless communication unit 7 outputs (transmits) an electrical signal (human body detection information, illuminance information, temperature information, humidity information) input from the control unit 1 to the outside via the antenna 6 using a wireless communication medium (radio wave). ) That is, in the present embodiment, the control unit 1, the antenna 6, and the wireless communication unit 7 correspond to an output unit. However, instead of the antenna 6 and the wireless communication unit 7, a wired communication interface (for example, a USB interface) that transmits an electric signal via a communication cable may be adopted as the output unit.

電源部８は、太陽電池80と、２次電池81と、太陽電池80の発電電力で２次電池81を充電し且つ２次電池81の放電電力と太陽電池80の発電電力を択一的に切り換えて出力する充放電部82と、充放電部82の出力電力を安定化させる定電源回路部83とを有する。定電源回路部83から制御部１及び各センサ部２〜５、無線通信部７に動作電源(例えば、電源電圧３ボルトの直流電源)が供給される。   The power supply unit 8 charges the secondary battery 81 with the solar battery 80, the secondary battery 81, and the generated power of the solar battery 80, and alternatively uses the discharged power of the secondary battery 81 and the generated power of the solar battery 80. It has a charge / discharge unit 82 that switches and outputs, and a constant power supply circuit unit 83 that stabilizes the output power of the charge / discharge unit 82. An operating power supply (for example, a DC power supply having a power supply voltage of 3 volts) is supplied from the constant power supply circuit unit 83 to the control unit 1, the sensor units 2 to 5, and the wireless communication unit 7.

図２は本実施形態のセンサ装置の外観斜視図を示し、図３は簡略化した断面図を示している。筐体10は、絶縁性を有する合成樹脂材料によって扁平な略角錐台形状に形成され、その内部に制御部１、各センサ部２〜５、アンテナ６、無線通信部７、電源部８が収納される。赤外線センサ部２は、筐体10内の前方(図２，図３における下方)中央に配置され、筐体10前面の中央に開口する窓孔11を通して、赤外線アレイセンサに赤外線が照射される。また、照度センサ部３と温度センサ部４と湿度センサ部５は、プリント配線板12に実装されており、筐体10前面に開口する丸孔13を通して、照度センサ部３に外光(可視光)が照射される。さらに、筐体10の前面には太陽電池80が配設されている。なお、電源部８の充放電部82や定電源回路部83は照度センサ部３などともにプリント配線板12に実装され、無線通信部７は別のプリント配線板14に実装されている(図３参照)。また、筐体10はねじなどの適宜の固定手段を用いて壁や天井などの造営物に取り付けられる。   FIG. 2 is an external perspective view of the sensor device of this embodiment, and FIG. 3 is a simplified cross-sectional view. The casing 10 is formed in a flat, substantially truncated pyramid shape from an insulating synthetic resin material, and the control unit 1, the sensor units 2 to 5, the antenna 6, the wireless communication unit 7, and the power supply unit 8 are housed therein. Is done. The infrared sensor unit 2 is disposed in the front (lower side in FIGS. 2 and 3) center in the housing 10, and infrared rays are irradiated to the infrared array sensor through the window hole 11 opened in the center of the front surface of the housing 10. The illuminance sensor unit 3, the temperature sensor unit 4, and the humidity sensor unit 5 are mounted on the printed wiring board 12, and the external light (visible light) is transmitted to the illuminance sensor unit 3 through a round hole 13 opened in the front surface of the housing 10. ) Is irradiated. Further, a solar cell 80 is disposed on the front surface of the housing 10. The charging / discharging unit 82 and the constant power supply circuit unit 83 of the power supply unit 8 are mounted on the printed wiring board 12 together with the illuminance sensor unit 3 and the wireless communication unit 7 is mounted on another printed wiring board 14 (FIG. 3). reference). The casing 10 is attached to a structure such as a wall or a ceiling using an appropriate fixing means such as a screw.

ここで、本実施形態のセンサ装置は、従来技術で説明したように空調機器や照明器具などの設備を制御する制御システムなどに用いられる。例えば、センサ装置で検出領域内に人が検出されると、制御システムのコントローラが照明器具を点灯させ、人が検出されなくなるとコントローラが照明器具を消灯させる。また、センサ装置で検出される照度に応じて、コントローラが照明器具を調光して室内の明るさを適正なレベルに維持する。あるいは、センサ装置で検出される温度及び湿度に応じて、コントローラが空調機器の設定温度及び設定湿度を調整することにより、室内を快適な環境に維持しつつ省電力化を図る。   Here, the sensor device of the present embodiment is used in a control system for controlling facilities such as an air conditioner and a lighting fixture as described in the related art. For example, when a person is detected in the detection area by the sensor device, the controller of the control system turns on the luminaire, and when no person is detected, the controller turns off the luminaire. Moreover, according to the illumination intensity detected with a sensor apparatus, a controller dimmes a lighting fixture and maintains the brightness of a room | chamber interior at an appropriate level. Alternatively, the controller adjusts the set temperature and set humidity of the air conditioner according to the temperature and humidity detected by the sensor device, thereby saving power while maintaining a comfortable environment in the room.

上述のように本実施形態のセンサ装置では、それぞれが異なる物理量(赤外線量、光量、温度、湿度)を検出する複数のセンサ部２〜５が、制御部１や無線通信部７や電源部８とともに、壁や天井などの造営物に取り付けられる筐体10内に収納されている。このため、従来であれば、人感センサと照度センサと温度センサと湿度センサが個別に設置されていたのに比べ、多種類の物理量を検出可能としつつ施工作業の簡素化を図ることができる。しかも、本実施形態のセンサ装置は、各センサ部２〜５の検出結果を無線信号によって外部に出力(送信)しているので、有線信号で出力する場合と比較して配線の施工作業が不要になるという利点がある。   As described above, in the sensor device of the present embodiment, the plurality of sensor units 2 to 5 that detect different physical quantities (infrared amount, light amount, temperature, humidity) are the control unit 1, the wireless communication unit 7, and the power supply unit 8. At the same time, it is housed in a housing 10 attached to a construction such as a wall or ceiling. For this reason, conventionally, compared to the case where the human sensor, the illuminance sensor, the temperature sensor, and the humidity sensor are individually installed, it is possible to simplify the construction work while making it possible to detect many kinds of physical quantities. . In addition, the sensor device according to the present embodiment outputs (transmits) the detection results of the sensor units 2 to 5 to the outside by wireless signals, so that it is not necessary to perform wiring work compared to the case of outputting by wired signals. There is an advantage of becoming.

なお、本実施形態では電源部８が太陽電池80と２次電池81と充放電部82を有しているが、これらの代わりにプラグ付きの電源コードを設け、電源コードを介して商用電源から供給される交流を定電源回路部83で直流に変換して動作電源を作成しても構わない。ただし、電源部８が太陽電池80と２次電池81と充放電部82を有する場合、電源コードを介して商用電源から給電される場合と比較して配線の施工作業が不要になるという利点がある。   In this embodiment, the power supply unit 8 includes a solar cell 80, a secondary battery 81, and a charge / discharge unit 82. Instead, a power cord with a plug is provided, and a commercial power supply is provided via the power cord. An operating power supply may be created by converting the supplied alternating current into direct current by the constant power supply circuit unit 83. However, when the power supply unit 8 includes the solar battery 80, the secondary battery 81, and the charging / discharging unit 82, there is an advantage that the wiring work is not required as compared with the case where power is supplied from a commercial power supply via the power cord. is there.

(実施形態２)
近年、快適性を表す指数として、PMV(Predicted Mean Vote)と呼ばれる温熱体感指標が用いられている。このPMV値を計算することによって、温度環境に関する６要素(空気温度、相対湿度、放射温度、気流速度、代謝量、着衣量)の組み合わせに対する快適度を求めることができる。 (Embodiment 2)
In recent years, a thermal sensation index called PMV (Predicted Mean Vote) has been used as an index representing comfort. By calculating this PMV value, it is possible to obtain a comfort level for a combination of six elements (air temperature, relative humidity, radiation temperature, air flow rate, metabolic rate, and clothing amount) related to the temperature environment.

そこで本実施形態のセンサ装置では、PMV値の算出に必要となる気流速度を検出するために、検出領域における空気の流れ(流速)を検出する流速センサ部９を備えている。さらに、室内の空気の汚れ具合を示す指標として二酸化炭素濃度が用いられていることに鑑み、本実施形態のセンサ装置は、検出領域における二酸化炭素濃度を検出するガスセンサ部20を備えている。なお、流速センサ部９及びガスセンサ部20を備えている点を除けば、本実施形態のセンサ装置は実施形態１のセンサ装置と共通の構成を有しているので、共通の構成要素には同一の符号を付して説明を省略する。   Therefore, the sensor device of the present embodiment includes a flow velocity sensor unit 9 that detects an air flow (flow velocity) in the detection region in order to detect an airflow velocity necessary for calculating the PMV value. Furthermore, in view of the fact that the carbon dioxide concentration is used as an index indicating the degree of indoor air contamination, the sensor device of the present embodiment includes a gas sensor unit 20 that detects the carbon dioxide concentration in the detection region. The sensor device of the present embodiment has the same configuration as that of the sensor device of the first embodiment except that the flow rate sensor unit 9 and the gas sensor unit 20 are provided. The description will be omitted.

流速センサ部９は、例えば、ヒータと、ヒータを挟んで対向する位置に配置されたサーモパイルとを有している。つまり、空気の流れがない状態では、ヒータを中心とした温度分布が対称となり、空気が流れている状態では、風上側の温度が低下するとともに風下側の温度が上昇して温度の平衡状態が崩れる。このような温度差をサーモパイルの熱起電力差として検出することにより、質量流量に応じた流速を計測することができる。ただし、流速の検出方式には様々な方式が実用化されており、本実施形態における流速センサ部９の検出方式は一例であって、これ以外の検出方式であっても構わない。   The flow velocity sensor unit 9 includes, for example, a heater and a thermopile disposed at a position facing each other across the heater. In other words, when there is no air flow, the temperature distribution around the heater is symmetrical, and when air is flowing, the temperature on the windward side decreases and the temperature on the leeward side rises, resulting in a temperature equilibrium state. Collapse. By detecting such a temperature difference as the thermoelectromotive force difference of the thermopile, the flow velocity according to the mass flow rate can be measured. However, various methods for detecting the flow velocity have been put into practical use, and the detection method of the flow velocity sensor unit 9 in this embodiment is an example, and other detection methods may be used.

ガスセンサ部20は、例えば、二酸化炭素分子が吸収する波長に合わせた赤外線を電気信号に変換することにより、検出領域における二酸化炭素濃度を検出するものである。ただし、二酸化炭素濃度の検出方式は一例であって、これ以外の検出方式であっても構わない。なお、流速センサ部９及びガスセンサ部20の検出結果も制御部１に出力され、制御部１から無線通信部７を介して外部(例えば、制御システムのコントローラ)に出力(送信)される。   The gas sensor unit 20 detects, for example, the carbon dioxide concentration in the detection region by converting infrared light matched to the wavelength absorbed by the carbon dioxide molecules into an electrical signal. However, the carbon dioxide concentration detection method is an example, and other detection methods may be used. The detection results of the flow velocity sensor unit 9 and the gas sensor unit 20 are also output to the control unit 1 and output (transmitted) from the control unit 1 to the outside (for example, a controller of the control system) via the wireless communication unit 7.

本実施形態のセンサ装置も実施形態１と同様に、多種類の物理量を検出可能としつつ施工作業の簡素化を図ることができる。   Similarly to the first embodiment, the sensor device of the present embodiment can simplify construction work while enabling detection of various types of physical quantities.
