ネットワークシステム、在不在判断方法、およびコントローラNetwork system, presence / absence determination method, and controller
　本発明は、人感センサを利用することによって部屋の中に人がいるか否かを判断するためのネットワークシステム、在不在判断方法、およびコントローラの技術に関する。 The present invention relates to a network system, a presence / absence determination method, and a controller technology for determining whether or not there is a person in a room by using a human sensor.
　住宅やオフィスなどの部屋に人がいるか否かを検知するための人感センサが知られている。そして、人感センサを他の装置のスイッチとして利用する技術も知られている。 There are known human sensors for detecting whether or not there is a person in a room such as a house or office. A technique of using a human sensor as a switch of another device is also known.
　たとえば、特開２００７－２２７３３０号公報（特許文献１）には、人感センサ付天井直付け照明器具が開示されている。特開２００７－２２７３３０号公報によると、天井直付け照明器具の点灯動作切り替えモードにおいて、通常の常時点灯する保安灯モードに加え、さらに人感センサ待機モードが設けられる。人感センサ待機モードには、感知終了後、保安灯は遅延回路により数十秒間点灯後、徐徐に暗くなり消灯するフェードアウト機能が設けられる。人感センサ部は、照明器具本体の器具本体周縁部に照明器具本体の中心から離れる方向に露出して設けられている。 For example, Japanese Unexamined Patent Application Publication No. 2007-227330 (Patent Document 1) discloses a ceiling-mounted lighting fixture with a human sensor. According to Japanese Patent Laid-Open No. 2007-227330, in the lighting operation switching mode of the direct lighting fixture, a human sensor standby mode is further provided in addition to the normal safety light mode in which the lighting is always performed. The human sensor standby mode is provided with a fade-out function in which, after the sensing is completed, the safety light is turned on for several tens of seconds by the delay circuit, and then gradually becomes dark and turns off. The human sensor part is provided to be exposed in a direction away from the center of the luminaire main body at the peripheral edge of the luminaire main body.
　また、特開２００９－１０８４８８号公報（特許文献２）には、門柱および玄関アプローチ構造が開示されている。特開２００９－１０８４８８号公報によると、当該構造は、敷地外部側の正面板材と、建物側の背面板材と、これら正面板材および背面板材間に設けられる門柱用機器とを備える。この門柱用機器は、人感センサと、この人感センサが人体等の発熱を感知した際に点灯する本体照明とを備える。この人感センサの感知エリアは、人感センサおよび正面板材の側端部どうしの延長線と、人感センサおよび背面板材の側端部どうしの延長線との間の範囲内である。これにより、正面板材および背面板材に対して真正面から近づく者は感知せずに、正面板材および背面板材の側方から近づく者だけを感知できる。 In addition, JP 2009-108488 A (Patent Document 2) discloses a gate post and a door approach structure. According to Japanese Patent Application Laid-Open No. 2009-108488, the structure includes a front plate member on the outside of the site, a back plate member on the building side, and a gatepost device provided between the front plate member and the back plate member. This gate post device includes a human sensor and main body lighting that is turned on when the human sensor detects heat generated by the human body or the like. The detection area of the human sensor is within a range between an extension line between the side edges of the human sensor and the front plate member and an extension line between the side ends of the human sensor and the rear plate member. Thereby, only those who approach from the side of a front board material and a back board material can be sensed, without detecting those who approach a front board material and a back board material from the front.
　また、特開２００５－２２２７２６号公報（特許文献３）には、照明システム及び照明手法が開示されている。特開２００５－２２２７２６号公報によると、照明システムは、街路の一部を所定の検知エリアとしこの検知エリア内における人の存在の有無を検知する人感センサと、街路に隣接された建物に設けられ人感センサが人の存在を有と検知したときに動作する照明器具とを備える。照明器具は、動作の変化が検知エリア内にいる人から認識できるとともに照明器具の照射範囲の少なくとも一部の範囲が検知エリア内にいる人から見て死角となるように設置される。 JP-A-2005-222726 (Patent Document 3) discloses an illumination system and an illumination technique. According to Japanese Patent Application Laid-Open No. 2005-222726, a lighting system is provided in a building adjacent to a street and a human sensor that detects a presence or absence of a person in the detection area with a part of the street as a predetermined detection area. And a lighting device that operates when the presence sensor detects the presence of a person. The luminaire is installed such that a change in operation can be recognized by a person in the detection area and at least a part of the irradiation range of the luminaire is a blind spot as seen from the person in the detection area.

　しかしながら、人感センサは所定時間以上停止している人を検知できない場合がある。すなわち、部屋の中に人がいるかを判断する場合において、当該部屋の中にいる人が所定時間以上停止している場合には、人感センサを利用しても部屋の中に人がいないと判断されてしまう虞がある。 However, the human sensor may not be able to detect a person who has stopped for a predetermined time. In other words, when determining whether there is a person in the room, if the person in the room has been stopped for a predetermined time or more, there is no person in the room even if the human sensor is used. There is a risk of being judged.

　＜ネットワークシステム１の全体構成＞
　まず、本実施の形態に係るネットワークシステムの全体構成について説明する。図１は、本実施の形態に係るネットワークシステム１の全体構成を示すイメージ図である。 <Overall configuration of network system 1>
First, the overall configuration of the network system according to the present embodiment will be described. FIG. 1 is an image diagram showing an overall configuration of a network system 1 according to the present embodiment.
　図１を参照して、本実施の形態に係るネットワークシステム１は、部屋４０１の入り口（ドア）の付近の天井に配置される人感センサ２００Ａと、部屋４０１の中央の天井に設置される人感センサ２００Ｂとを備える。たとえば、人感センサ２００Ａ，２００Ｂは、動いている熱源を検知するものである。 Referring to FIG. 1, network system 1 according to the present embodiment includes human sensor 200 </ b> A arranged on the ceiling near the entrance (door) of room 401 and a person installed on the center ceiling of room 401. And a sensor 200B. For example, the human sensors 200 </ b> A and 200 </ b> B detect a moving heat source.
　人感センサ２００Ａは、部屋４０１の入り口にいる人を検知する。人感センサ２００Ｂは、部屋４０１の内部にいる人を検知する。人感センサ２００Ａのセンシングエリア２０１Ａと人感センサ２００Ｂのセンシングエリア２０１Ｂは重ならないことが好ましい。 The human sensor 200 </ b> A detects a person at the entrance of the room 401. The human sensor 200 </ b> B detects a person inside the room 401. It is preferable that the sensing area 201A of the human sensor 200A and the sensing area 201B of the human sensor 200B do not overlap.
　ネットワークシステム１は、照明３０１Ａ，３０１Ｂと、エアコン３０２と、テレビ３０３とを含む。なお、ネットワークシステム１は、照明３０１Ａ，３０１Ｂと、エアコン３０２と、テレビ３０３以外の家電を含んでもよい。 The network system 1 includes lights 301A and 301B, an air conditioner 302, and a television 303. The network system 1 may include home appliances other than the lightings 301 </ b> A and 301 </ b> B, the air conditioner 302, and the television 303.
　ネットワークシステム１は、人感センサ２００Ａ，２００Ｂと、照明３０１Ａ，３０１Ｂと、エアコン３０２と、テレビ３０３とを制御するためのコントローラ１００を含む。換言すれば、コントローラ１００は、有線あるいは無線のネットワークを介して、人感センサ２００Ａ，２００Ｂと、照明３０１Ａ，３０１Ｂと、エアコン３０２と、テレビ３０３などとデータ通信が可能である。 The network system 1 includes a controller 100 for controlling human sensors 200A and 200B, lights 301A and 301B, an air conditioner 302, and a television 303. In other words, the controller 100 can perform data communication with the human sensors 200A and 200B, the lights 301A and 301B, the air conditioner 302, the television 303, and the like via a wired or wireless network.
　コントローラ１００は、ネットワークとして、たとえば、無線ＬＡＮ、ZigBee（登録商標）、Bluetooth（登録商標）、有線ＬＡＮ（Local　Area　Network）、またはＰＬＣ（Power　Line　Communications）などを利用する。コントローラ１００は、持ち運び可能であってもよいし、テーブル上に載置されたベースに着脱自在であってもよいし、部屋の壁に固設されるものであってもよい。 The controller 100 uses, for example, a wireless LAN, ZigBee (registered trademark), Bluetooth (registered trademark), a wired LAN (Local Area Network), or a PLC (Power Line Communications) as a network. The controller 100 may be portable, may be detachable from a base placed on a table, or may be fixed to a wall of a room.
　＜ネットワークシステム１の動作概要＞
　次に、本実施の形態に係るネットワークシステム１（特にコントローラ１００）の動作概要について説明する。 <Operation overview of network system 1>
Next, an outline of the operation of the network system 1 (particularly the controller 100) according to the present embodiment will be described.
　図１を参照して、本実施の形態に係るコントローラ１００は、ネットワークを介して、人感センサ２００Ａ，２００Ｂから、人を検知したことを示す情報、または人を検知していないことを示す情報などを受信する。 Referring to FIG. 1, controller 100 according to the present embodiment provides information indicating that a person has been detected or information indicating that a person has not been detected from human sensors 200A and 200B via a network. Etc.
　コントローラ１００は、人感センサ２００Ｂからの情報に基づいて、人感センサ２００Ｂが人を検知すると、部屋４０１の中に人がいると判断する。あるいは、コントローラ１００は、人感センサ２００Ａからの情報に基づいて、人感センサ２００Ａおよび人感センサ２００Ｂの少なくともいずれかが人を検知すると、部屋４０１の中に人がいると判断してもよい。 Controller 100 determines that there is a person in room 401 when human sensor 200B detects a person based on information from human sensor 200B. Alternatively, controller 100 may determine that there is a person in room 401 when at least one of human sensor 200A and human sensor 200B detects a person based on information from human sensor 200A. .
　ここで、部屋４０１の中に人がいるのに、人感センサ２００Ｂが人を検知しない場合がある。たとえば、部屋４０１の中の人が動きを止めている場合には、人感センサ２００Ｂが人を検知しない場合がある。 Here, there are cases where the human sensor 200B does not detect a person even though there is a person in the room 401. For example, when a person in the room 401 stops moving, the human sensor 200B may not detect the person.
　そこで、本実施の形態に係るコントローラ１００は、部屋４０１の中に人がいると判断した後は、人感センサ２００Ｂが人を検知しておらず人感センサ２００Ａが人を検知したときに、部屋４０１に人がいない（部屋４０１から人がいなくなった）と判断する。そして、それ以降は、コントローラ１００が、人感センサ２００Ａが人を検知するまで、部屋４０１に人がいないと判断する。 Therefore, after the controller 100 according to the present embodiment determines that there is a person in the room 401, the human sensor 200B does not detect a person and the human sensor 200A detects a person. It is determined that there is no person in room 401 (no person has left room 401). Thereafter, the controller 100 determines that there is no person in the room 401 until the human sensor 200A detects the person.
　あるいは、コントローラ１００は、部屋４０１の中に人がいると判断した後は、人感センサ２００Ｂが人を検知しておらず人感センサ２００Ａが人を検知した状態を経てから、人感センサ２００Ａ，２００Ｂがともに人を検知しなかったときに、部屋４０１に人がいない（部屋４０１から人がいなくなった）と判断する。そして、それ以降は、コントローラ１００が、人感センサ２００Ａおよび人感センサ２００Ｂの少なくともいずれかが人を検知するまで、部屋４０１に人がいないと判断する。 Alternatively, after the controller 100 determines that there is a person in the room 401, after the human sensor 200B has not detected the person and the human sensor 200A has detected the person, the human sensor 200A. , 200B does not detect any person, it is determined that there is no person in the room 401 (no person has left the room 401). After that, the controller 100 determines that there is no person in the room 401 until at least one of the human sensor 200A and the human sensor 200B detects the person.
　コントローラ１００は、部屋４０１に人がいると判断した場合に、照明３０１Ａ，３０１Ｂ、エアコン３０２、あるいはテレビ３０３をＯＮする。コントローラ１００は、部屋４０１に人がいないと判断した場合に、照明３０１Ａ，３０１Ｂ、エアコン３０２、あるいはテレビ３０３をＯＦＦする。ただし、コントローラ１００は、上記の判断結果に基づいて、照明３０１Ａ，３０１Ｂと、エアコン３０２と、テレビ３０３以外の家電の動作を制御しても良い。 When the controller 100 determines that there is a person in the room 401, the controller 301 turns on the lights 301A and 301B, the air conditioner 302, or the television 303. When the controller 100 determines that there is no person in the room 401, the controller 100 turns off the lights 301A and 301B, the air conditioner 302, or the television 303. However, the controller 100 may control operations of home appliances other than the lightings 301 </ b> A and 301 </ b> B, the air conditioner 302, and the television 303 based on the above determination result.
　このように、本実施の形態に係るネットワークシステム１は、部屋４０１の入り口のエリアをセンシングするための人感センサ２００Ａの検知結果と、当該入り口よりも部屋４０１の内側のエリアをセンシングするための人感センサ２００Ｂと検知結果とに基づいて、部屋４０１に人がいるか否かを判断するため、より正確に部屋の中に人がいるか否かを判断することができる。 As described above, the network system 1 according to the present embodiment senses the detection result of the human sensor 200A for sensing the area at the entrance of the room 401 and the area for sensing the area inside the room 401 from the entrance. Since it is determined whether there is a person in the room 401 based on the human sensor 200B and the detection result, it is possible to more accurately determine whether there is a person in the room.
　以下、このような機能を実現するためのネットワークシステム１の具体的な構成について詳述する。 Hereinafter, a specific configuration of the network system 1 for realizing such a function will be described in detail.

In this case, CPU 110 repeats the processing from step S110 when human sensor 200A detects a person (YES in step S113).
　そして、ＣＰＵ１１０は、人感センサ２００Ａが人を検知しなかった場合（ステップＳ１１３においてＮＯである場合）、すなわち、人感センサ２００Ａが人を検知しつつ人感センサ２００Ｂが人を検知していないと認識してから、人感センサ２００Ａと人感センサ２００Ｂとが人を検知しないと認識した場合（ステップＳ１１３においてＹＥＳである場合）、部屋４０１に人がいないと判断する（ステップＳ１１４）。 Then, CPU 110 does not detect a person when human sensor 200A does not detect a person (NO in step S113), that is, human sensor 200B detects a person while human sensor 200A does not detect a person. When the human sensor 200A and the human sensor 200B recognize that no person is detected (YES in step S113), it is determined that there is no person in the room 401 (step S114).
