　以下、本発明の実施の形態（実施例）を図面に基づいてより詳細に説明する。
　図１は、本実施例における危機管理システムの構成を説明するためのブロック図、図２は、図１の危機管理システムのシステム構成図である。 Hereinafter, embodiments (examples) of the present invention will be described in more detail with reference to the drawings.
FIG. 1 is a block diagram for explaining the configuration of the crisis management system according to the present embodiment, and FIG. 2 is a system configuration diagram of the crisis management system of FIG.
　図１、２に示すように、本実施例の危機管理システム１０は、作業者２２の位置情報を取得する位置情報取得手段１２と、作業者２２の生体・行動情報を取得する生体・行動情報取得手段１４と、位置情報および生体・行動情報から作業現場における危険エリアおよび／または危険行動を判断する危機検知装置１６とを備えている。 As shown in FIGS. 1 and 2, the crisis management system 10 according to the present embodiment includes position information acquisition means 12 that acquires position information of the worker 22, and living body / behavior information that acquires the biological / behavior information of the worker 22. An acquisition unit 14 and a crisis detection device 16 that determines a dangerous area and / or dangerous behavior at a work site from position information and biological / behavior information are provided.
　位置情報取得手段１２として、本実施例では、送信機１８と受信機２０とを含んで構成されている。
　図２に示すように、送信機１８は、作業者２２がそれぞれ所有している。また、送信機１８には、どの作業者２２が所有しているかを識別するための作業者識別情報取得手段２４を備えている。なお、作業者識別情報取得手段２４としては、例えば、送信機１８の個体識別情報や、送信機１８に登録されている作業者識別情報などを取得するソフトウェアにより構成することができ、送信機１８から受信機２０に作業者識別情報を送信することで、危機検知装置１６は作業者識別情報を取得することができる。 In this embodiment, the position information acquisition unit 12 includes a transmitter 18 and a receiver 20.
As shown in FIG. 2, the transmitter 18 is owned by the operator 22. Further, the transmitter 18 is provided with worker identification information acquisition means 24 for identifying which worker 22 owns. Note that the worker identification information acquisition unit 24 can be configured by software for acquiring individual identification information of the transmitter 18, worker identification information registered in the transmitter 18, and the like. By transmitting the worker identification information from the receiver 20 to the receiver 20, the crisis detection device 16 can acquire the worker identification information.
　なお、本実施例では、図２に示すように、作業現場２６が複数のエリア２６ａ，２６ｂ，２６ｃ，２６ｄに区分けされており、各エリアには、送信機１８と接続される複数の受信機２０が設けられている。 In this embodiment, as shown in FIG. 2, the work site 26 is divided into a plurality of areas 26 a, 26 b, 26 c, and 26 d, and each area includes a plurality of receivers connected to the transmitter 18. 20 is provided.
　このように構成された本実施例における位置情報取得手段１２は、送信機１８から送信された信号を、各受信機２０が受信する際の信号強度の減衰量の差や、送信機１８から各受信機２０に送信される信号の到達時間の差に基づいて位置情報を取得することができる。 The position information acquisition means 12 in the present embodiment configured as described above has a difference in attenuation amount of signal strength when each receiver 20 receives a signal transmitted from the transmitter 18, and each signal from the transmitter 18. The position information can be acquired based on the difference in arrival times of signals transmitted to the receiver 20.
　なお、このような位置情報取得手段１２は、工場やプラントなどの建設現場において屋内外での運用を考慮すれば、例えば、ＲＦＩＤ（Radio Frequency Identifier）、Ｗｉ－Ｆｉ（登録商標）、Ｂｌｕｅｔｏｏｔｈ（登録商標）、ＺｉｇＢｅｅ（登録商標）などの近距離無線通信を用いて構成することが好ましい。一方で、屋外のみでの運用であれば、他にも、ＧＰＳ（Global Positioning System）やＧＬＯＮＡＳＳ（Global Navigation Satellite System）などの衛星測位システムを利用することもできる。 Such position information acquisition means 12 is, for example, an RFID (Radio Frequency Identifier), Wi-Fi (registered trademark), or Bluetooth (registered) in consideration of indoor / outdoor operation at a construction site such as a factory or a plant. (Trademark), ZigBee (registered trademark), etc. On the other hand, if the operation is performed only outdoors, other satellite positioning systems such as GPS (Global Positioning System) and GLONASS (Global Navigation Satellite System) can be used.
　なお、本実施例では、複数の受信機２０は互いに接続されローカルネットワークを形成し、また、受信機２０と危機検知装置１６はネットワーク２８により接続されている。なお、本明細書において、「ローカルネットワーク」とは、例えば、イントラネットなどのローカルエリアネットワーク（ＬＡＮ）やワイヤレスセンサーネットワークなど、閉じられたネットワークのことをいい、他の通信規格を利用したネットワークを利用しても構わない。また、本明細書において「ネットワーク」とは、上述するローカルネットワークに加えて、インターネットなどのワイドエリアネットワーク（ＷＡＮ）なども含むネットワークのことをいう。 In the present embodiment, the plurality of receivers 20 are connected to each other to form a local network, and the receiver 20 and the crisis detection device 16 are connected by a network 28. In this specification, “local network” means a closed network such as a local area network (LAN) such as an intranet or a wireless sensor network, and a network using another communication standard is used. It doesn't matter. In addition, in this specification, “network” refers to a network including a wide area network (WAN) such as the Internet in addition to the local network described above.
　位置情報取得手段１２により取得した作業者２２の位置情報は、作業者識別情報と関連付けられて危機検知装置１６に送られ、危機検知装置１６は、事前に記録されたエリアマップと照合することにより、作業者２２がどのエリア２６ａ～２６ｄにいるかを判断している。 The position information of the worker 22 acquired by the position information acquisition means 12 is sent to the crisis detection device 16 in association with the worker identification information, and the crisis detection device 16 collates with the area map recorded in advance. It is determined which area 26a to 26d the worker 22 is in.
　また、危機検知装置１６には、位置情報取得手段１２により取得した作業者２２の位置情報と、位置情報の取得時刻とを関連付けて記録される。このように、位置情報と取得時刻とを関連付けて記録することで、作業者２２の動きをより正確に把握することができる。 Also, the crisis detection device 16 records the position information of the worker 22 acquired by the position information acquisition unit 12 in association with the acquisition time of the position information. Thus, by recording the positional information and the acquisition time in association with each other, the movement of the worker 22 can be grasped more accurately.
　また、生体・行動情報取得手段１４では、作業者２２の体温や心拍数などの生体に関する情報や、作業者２２の加速度の変化など行動に関する情報、作業者２２の周囲の外気温や湿度などのその他の情報を取得するように構成されている。 The living body / behavior information acquisition unit 14 also includes information on the living body such as the body temperature and heart rate of the worker 22, information on the action such as a change in the acceleration of the worker 22, and the outside temperature and humidity around the worker 22. It is configured to acquire other information.
　なお、生体・行動情報取得手段１４としては、例えば、加速度センサー、体温センサー、心拍数センサー、外気温センサー、湿度センサー、気圧センサーなどを用いることができ、これらを組み合わせて用いても構わない。また、このようなセンサーは、作業者２２が所有する送信機１８に組み込んでもよいし、外気温センサーや湿度センサーなどは、送信機１８とは別の装置として、エリア２６ａ～２６ｄごとに設置しても構わない。 As the living body / behavior information acquisition means 14, for example, an acceleration sensor, a body temperature sensor, a heart rate sensor, an outside air temperature sensor, a humidity sensor, an atmospheric pressure sensor, or the like may be used, and these may be used in combination. Further, such a sensor may be incorporated in the transmitter 18 owned by the operator 22, and an outside air temperature sensor, a humidity sensor, and the like are installed for each of the areas 26 a to 26 d as a separate device from the transmitter 18. It doesn't matter.
　このようにして得られた作業者２２の位置情報と、生体・行動情報とに基づいて、危機検知装置１６は、危険エリアおよび／または危険行動を特定する。 Based on the position information of the worker 22 and the biological / behavior information obtained in this way, the crisis detection device 16 identifies a dangerous area and / or dangerous behavior.
　具体的には、生体・行動情報取得手段１４として加速度センサーを用いる場合には、危機検知装置１６は、加速度センサーにより得られた加速度情報に基づき、作業者２２の変則的な行動を検知するとともに、変則的な行動が発生した位置情報を取得する。 Specifically, when an acceleration sensor is used as the living body / behavior information acquisition unit 14, the crisis detection device 16 detects the anomalous behavior of the worker 22 based on the acceleration information obtained by the acceleration sensor. The location information where the anomalous behavior has occurred is acquired.
　ここで変則的な行動とは、加速度の急な変化などである。このように、加速度の急な変化が生じる箇所では、土地が陥没していたりケーブルが這っていたりして労働者が躓いたと判断することができる。このため、エリアマップにおいて、変則的な行動が頻出する位置を危険エリアとして特定することができる。 Here, the anomalous behavior is a sudden change in acceleration. In this way, it is possible to determine that the worker has crawled because the land has collapsed or the cable has crushed at a place where a sudden change in acceleration occurs. For this reason, in the area map, a position where irregular behavior frequently appears can be specified as a dangerous area.
　また、生体・行動情報取得手段１４として、体温センサーや外気温センサー、湿度センサーを用いる場合には、体温センサーや外気温センサー、湿度センサーにより得られた作業者２２の体温情報や作業者２２の周囲の外気温情報、湿度情報に基づいて、作業者２２の健康状態を検知する。 Further, when a body temperature sensor, an outside air temperature sensor, or a humidity sensor is used as the living body / behavior information acquisition means 14, the body temperature information of the worker 22 obtained by the body temperature sensor, the outside air temperature sensor, or the humidity sensor, or the worker 22 Based on surrounding ambient temperature information and humidity information, the health state of the worker 22 is detected.
　このような情報からは、例えば、作業者２２の日々の体調の変化や熱中症の初期症状などを健康状態として検知することができ、作業者２２が体調不良となるまえに予防を講じることができる。
　また、生体・行動情報取得手段１４として、気圧センサーを用いる場合には、気圧センサーにより得られた気圧情報に基づき、作業者２２の位置情報として高さを取得することができる。これにより、位置情報として平面的な位置のみならず、立体的に作業者２２が居る場所を把握することができ、例えば、高所作業者に特有の危険エリア、危険行動の特定が可能となる。 From such information, for example, changes in the daily physical condition of the worker 22, initial symptoms of heat stroke, and the like can be detected as a healthy state, and prevention can be taken before the worker 22 becomes unwell. it can.
Further, when a barometric pressure sensor is used as the living body / behavior information acquisition unit 14, the height can be acquired as the position information of the operator 22 based on the barometric pressure information obtained by the barometric pressure sensor. Thereby, not only a planar position but also a three-dimensional place where the worker 22 is present can be grasped as position information.
