Description

見守り通知装置Watch notification device
　本発明は見守り通知装置に関し、より詳細には、見守りの対象者が使用する機器での資源の消費量を利用して対象者を見守る見守り通知装置に関する。 The present invention relates to a watch notification device, and more particularly, to a watch notification device that uses a resource consumption in a device used by a watch target person to watch the target person.
　従来、利用者の日々の電力の使用状況をパターン化したデータと、クライアント端末から得られた電力の使用状況のデータとの差分を求め、差分が閾値を越えた場合に、異常発生と判定してあらかじめ定めた宛先に通知する技術が提案されている（たとえば、日本国特許出願番号２００７－１８３８９０参照、以下“文献１”という）。 Conventionally, the difference between the data that patterned the user's daily power usage and the data on the power usage obtained from the client terminal is obtained, and if the difference exceeds the threshold, it is determined that an abnormality has occurred. A technique for notifying a predetermined destination is proposed (for example, refer to Japanese Patent Application No. 2007-183890, hereinafter referred to as “Document 1”).
　文献１に記載された技術では、利用者の電力の使用状況が平時とは異なる場合に、利用者に異常が生じたと判断して通知している。 In the technique described in Document 1, when the usage state of the user's power is different from the normal time, it is determined that an abnormality has occurred to the user and notified.
　しかしながら、電力の使用状況が平時とは異なるからといって、利用者に異常が生じているとは限らないから、文献１に記載された技術では、誤報の頻度が高くなる可能性がある。また、高齢者を見守りの対象者として、家族などに高齢者の生活状況を通知するような用途では、文献１に記載された技術を使用したとしても、異常と判断されたときにのみ通知されるだけであって、異常の兆候などを見出すことはできない。 However, just because the usage status of power is different from that in normal times, it does not necessarily mean that an abnormality has occurred in the user, so the technique described in Document 1 may increase the frequency of false alarms. In addition, in applications where the elderly are watched over, such as notification of the living conditions of the elderly to the family, etc., even if the technique described in Document 1 is used, it is notified only when it is determined to be abnormal. You can't find any signs of abnormality.
　本発明は、誤報の頻度を低減可能であり、また対象者の異常の兆候を見出すことが可能になる見守り通知装置を提供することを目的とする。 The object of the present invention is to provide a watch notification device that can reduce the frequency of false alarms and can detect signs of abnormality of the subject.
　本発明に係る見守り通知装置は、取得部と、評価部と、生成部と、通信部とを備える。前記取得部は、見守られる対象者が生活する対象空間で使用される少なくとも一つの対象機器による資源の消費量を、計測装置から取得する。前記評価部は、前記取得部が平時に取得した前記資源の消費量である第１の消費量と前記取得部が取得した前記資源の最新の消費量である第２の消費量との差異を評価して、得られた結果を評価結果として出力する。前記生成部は、前記評価部の前記評価結果に応じて異なる内容の報知情報を生成する。前記通信部は、前記生成部が生成した前記報知情報を、登録されている報知装置に電気通信回線を通して送信する。 The watch notification device according to the present invention includes an acquisition unit, an evaluation unit, a generation unit, and a communication unit. The said acquisition part acquires the consumption of the resource by the at least 1 object apparatus used in the object space where the object person to be watched lives lives from a measuring device. The evaluation unit calculates a difference between a first consumption that is the consumption of the resource acquired by the acquisition unit in normal time and a second consumption that is the latest consumption of the resource acquired by the acquisition unit. Evaluate and output the result as an evaluation result. The said production | generation part produces | generates the alerting | reporting information of a different content according to the said evaluation result of the said evaluation part. The communication unit transmits the notification information generated by the generation unit to a registered notification device through an electric communication line.
　本発明の見守り通知装置の構成によれば、誤報の頻度を低減することが可能になり、また対象者の異常の兆候を見出せる可能性がある。 According to the configuration of the watch notification device of the present invention, the frequency of false alarms can be reduced, and there is a possibility that a sign of abnormality of the subject can be found.

　図１に示すように、以下に説明する見守り通知装置１０は、取得部１１と評価部１２と生成部１３と通信部１４とを備える。取得部１１は、見守られる対象者が生活する対象空間で使用される少なくとも一つの対象機器３１による資源の消費量を、計測装置３０から取得する。評価部１２は、取得部１１が平時に取得した資源の消費量である第１の消費量と取得部１１が取得した最新の資源の消費量である第２の消費量との差異を評価する。評価部１２は、得られた結果を評価結果として出力する。生成部１３は、評価部１２の評価結果に応じて異なる内容の報知情報を生成する。通信部１４は、生成部１３が生成した報知情報を、登録されている報知装置２０に電気通信回線２１を通して送信する。なお平時とは、たとえば、資源の消費量が第１の消費量から所定の範囲内にある状態である。 As shown in FIG. 1, the watch notification device 10 described below includes an acquisition unit 11, an evaluation unit 12, a generation unit 13, and a communication unit 14. The acquisition unit 11 acquires the amount of resource consumption by the at least one target device 31 used in the target space where the target person to be watched lives from the measuring device 30. The evaluation unit 12 evaluates the difference between the first consumption that is the resource consumption acquired by the acquisition unit 11 during normal times and the second consumption that is the latest resource consumption acquired by the acquisition unit 11. . The evaluation unit 12 outputs the obtained result as an evaluation result. The generation unit 13 generates notification information having different contents according to the evaluation result of the evaluation unit 12. The communication unit 14 transmits the notification information generated by the generation unit 13 to the registered notification device 20 through the electric communication line 21. The normal time is a state in which the resource consumption is within a predetermined range from the first consumption.
　本実施形態の見守り通知装置１０によれば、平時の消費量である第１の消費量と最新の消費量である第２の消費量との差異を評価し、評価に応じて異なる内容の報知情報を生成するから、単純に閾値を用いて異常と判断する場合に比べると、誤報の頻度を低減することが可能になる。また、第１の消費量と第２の消費量との差異に応じた内容の報知情報を生成するから、差異の程度や差異の生じ方などの情報を評価することによって、対象者の異常の兆候を見出せる可能性がある。 According to the watch notification device 10 of the present embodiment, the difference between the first consumption, which is normal consumption, and the second consumption, which is the latest consumption, is evaluated, and different contents are notified according to the evaluation. Since the information is generated, it is possible to reduce the frequency of false alarms as compared to the case where the abnormality is simply determined using a threshold value. In addition, since the notification information is generated according to the difference between the first consumption amount and the second consumption amount, by evaluating information such as the degree of difference and how the difference occurs, Signs may be found.
　報知情報は、報知装置２０の管理者から対象者に連絡する方法である連絡情報を含むことが望ましい。また、通信部１４は、あらかじめ定めた時刻に報知情報を報知装置２０に通知する定時通知と、報知情報が確定した時点で報知情報を報知装置２０に通知する即時通知とを行うことが可能であることが望ましい。この場合、生成部１３は、定時通知か即時通知かに応じて連絡情報の内容を変更することが望ましい。 It is desirable that the notification information includes contact information that is a method for contacting the target person from the administrator of the notification device 20. Further, the communication unit 14 can perform a scheduled notification that notifies the notification device 20 of the notification information at a predetermined time and an immediate notification that notifies the notification device 20 of the notification information when the notification information is determined. It is desirable to be. In this case, it is desirable that the generation unit 13 changes the content of the contact information depending on whether it is a scheduled notification or an immediate notification.
　計測装置３０は、対象空間で使用される複数の機器３のうちの着目する複数の対象機器３１について、資源の消費量を個別に計測することが望ましい。この場合、評価部１２は、対象機器３１ごとの資源の消費量の組み合わせを用いて緊急度を設定し、生成部１３は、緊急度に応じて異なる内容の報知情報を生成することが望ましい。 It is desirable that the measuring device 30 individually measures resource consumption for a plurality of target devices 31 of interest among the plurality of devices 3 used in the target space. In this case, it is desirable that the evaluation unit 12 sets the urgency level using a combination of resource consumption for each target device 31, and the generation unit 13 generates notification information with different contents according to the urgency level.
　報知装置２０は、表示装置２０１を備え、報知情報は、第１の消費量と第２の消費量とを含み、第１の消費量と第２の消費量とを表示装置２０１の画面に並べて表示させることが望ましい。 The notification device 20 includes a display device 201. The notification information includes a first consumption amount and a second consumption amount, and the first consumption amount and the second consumption amount are arranged on the screen of the display device 201. It is desirable to display.
　以下に説明する構成例は、対象空間が住宅４０であり、対象者が高齢者である場合を想定している。ただし、対象空間は、対象者が長期に亘って生活する空間であれば住宅４０に限らず、施設における居室などであってもよい。また、対象者も高齢者に限らず、同居していない家族などであってもよい。 The configuration example described below assumes a case where the target space is the house 40 and the target person is an elderly person. However, the target space is not limited to the house 40 as long as the target person lives for a long period of time, and may be a room in a facility. The target person is not limited to an elderly person, and may be a family who does not live together.
　見守り通知装置１０から報知情報を受け取る報知装置２０は、たとえば、スマートフォン、タブレット端末、モバイル型のパーソナルコンピュータなどである。報知装置２０は、表示装置２０１としてのディスプレイと、操作装置２０２としてのタッチパネルあるいはキーボードを備える。電気通信回線２１は、インターネット上に構築されるＶＰＮ（Virtual Private Network）を想定しているが、移動体電話網であってもよい。また、電気通信回線２１が、インターネットと移動体電話網との両方を含む場合には、インターネットと移動体電話網との中継を行うゲートウェイ、サーバなどの装置が電気通信回線２１に必要である。 The notification device 20 that receives the notification information from the watch notification device 10 is, for example, a smartphone, a tablet terminal, a mobile personal computer, or the like. The notification device 20 includes a display as the display device 201 and a touch panel or a keyboard as the operation device 202. The telecommunications line 21 is assumed to be a VPN (Virtual Private Network) constructed on the Internet, but may be a mobile telephone network. When the telecommunication line 21 includes both the Internet and the mobile telephone network, a device such as a gateway or a server that relays between the Internet and the mobile telephone network is required for the telecommunication line 21.
　見守り通知装置１０は、独立した装置であってもよいが、以下では、ＨＥＭＳコントローラ（HEMS: Home Energy Management System）の一部の機能として実現されている場合を想定する。ＨＥＭＳコントローラは、住宅４０で使用される機器３の動作を管理するコントローラである。 The watch notification device 10 may be an independent device, but in the following, it is assumed that the device is realized as a partial function of a HEMS controller (HEMS: Home Energy Management System). The HEMS controller is a controller that manages the operation of the device 3 used in the house 40.
　以下に、実施形態をさらに詳しく説明する。以下に説明する実施形態では、図１のように、住宅４０に設けられる機器３が電気を資源として動作する構成である場合を例として説明する。つまり、取得部１１が計測装置３０から資源の消費量を取得する機器（対象機器）３１は、電気機器を想定している。 Hereinafter, the embodiment will be described in more detail. In the embodiment described below, as shown in FIG. 1, a case where the device 3 provided in the house 40 is configured to operate using electricity as a resource will be described as an example. That is, the device (target device) 31 from which the acquisition unit 11 acquires the resource consumption from the measurement device 30 is assumed to be an electrical device.
　ただし、ガスあるいは水道水を資源として動作する機器を対象機器３１として用いる場合でも、以下に説明する技術的思想は適用可能である。たとえば、調理、給湯、暖房などに関する機器であってガスを資源として動作する機器を対象機器３１として用いる場合には、計測装置３０であるガスメータが計測したガスの流量を監視することにより、対象機器３１の動作状態を把握することが可能である。たとえば、給水、給湯などに関する機器であって水道水を資源として動作する機器を対象機器３１として用いる場合には、計測装置３０である水道メータが計測した流量を監視することにより、対象機器３１の動作状態を把握することが可能である。 However, even when a device that operates using gas or tap water as a resource is used as the target device 31, the technical idea described below can be applied. For example, in the case where a device that operates on gas as a resource and is a device related to cooking, hot water supply, heating, etc., the target device 31 is monitored by monitoring the gas flow rate measured by the gas meter that is the measuring device 30. It is possible to grasp the operation state of 31. For example, when a device that operates on tap water as a resource and is related to water supply, hot water supply, etc., is used as the target device 31, the flow rate measured by a water meter that is the measuring device 30 is monitored. It is possible to grasp the operating state.
　本実施形態は、電力を資源として動作する電気機器を対象機器３１として用いるから、対象機器３１で使用した資源（電力）の消費量は、住宅４０に設置された分電盤３２に併設または内蔵された計測装置３０が電力量として計測する。計測装置３０は、たとえば、分電盤３２において複数系統に分岐した分岐回路に流れる電流をそれぞれ計測するセンサ（図示せず）を備える。計測装置３０は、それぞれのセンサが計測した電流値と、分岐回路の線間電圧とを用いることにより、分岐回路の各々で消費される電力量を単位時間ごとに算出する。センサは、たとえば、分岐回路の電路に取り付けられるクランプ式の電流トランス、分電盤３２に内蔵されたロゴスキーコイルなどである。 In the present embodiment, since an electric device that operates using power as a resource is used as the target device 31, the consumption of the resource (power) used in the target device 31 is provided or built in the distribution board 32 installed in the house 40. The measured measuring device 30 measures the amount of power. The measuring device 30 includes, for example, sensors (not shown) that respectively measure currents flowing in branch circuits branched into a plurality of systems in the distribution board 32. The measuring device 30 calculates the amount of power consumed by each branch circuit per unit time by using the current value measured by each sensor and the line voltage of the branch circuit. The sensor is, for example, a clamp-type current transformer attached to the electric circuit of the branch circuit, a Rogowski coil built in the distribution board 32, or the like.
　計測装置３０が電力量を計測する単位時間は、３０秒、１分、２分、５分、１０分、１時間などから選択される。ただし、これらの値は一例であって、さらに短い時間を単位時間として電力量を計測してもよい。また、計測装置３０は、分岐回路ごとの電力量ではなく、機器３ごとの電力量を計測する構成を採用することも可能である。 The unit time for the measuring device 30 to measure the electric energy is selected from 30 seconds, 1 minute, 2 minutes, 5 minutes, 10 minutes, 1 hour, and the like. However, these values are merely examples, and the electric energy may be measured using a shorter time as a unit time. In addition, the measuring device 30 may employ a configuration that measures the amount of power for each device 3 instead of the amount of power for each branch circuit.
　一般に、住宅４０に設置された分電盤３２では、空調機器、電子レンジ、ＩＨクッキングヒータ（IH: Induction Heating）のように単位時間当たりの消費電力量の最大値が比較的大きい機器３には１回路ずつの分岐回路が割り当てられる。一方、分電盤３２では、アウトレットに接続される機器、照明器具のように単位時間当たりの消費電力量の最大値が比較的小さい機器３については、部屋を単位として分岐回路が割り当てられることが多い。分岐回路が単独の機器３に割り当てられている場合は、計測装置３０が計測する分岐回路ごとの消費電力量から、機器３ごとの消費電力量を求めることができる。一方、分岐回路が部屋単位に割り当てられている場合でも、例えば機器３ごとにセンサを設けることで、機器３ごとの消費電力量を求めることができる。以下では、消費電力量を計測する単位について分岐回路か個別の機器３（対象機器３１）かを区別せずに、機器３（対象機器３１）と記載して説明する。 In general, the distribution board 32 installed in the house 40 is 1 for devices 3 having a relatively large maximum power consumption per unit time, such as air conditioners, microwave ovens, and IH cooking heaters (IH: Induction Heating). A branch circuit for each circuit is assigned. On the other hand, in the distribution board 32, for a device 3 having a relatively small maximum power consumption amount per unit time, such as a device connected to an outlet or a lighting fixture, a branch circuit may be assigned in units of rooms. Many. When the branch circuit is assigned to the single device 3, the power consumption for each device 3 can be obtained from the power consumption for each branch circuit measured by the measuring device 30. On the other hand, even when the branch circuit is assigned to each room, for example, by providing a sensor for each device 3, the power consumption for each device 3 can be obtained. In the following description, the unit for measuring the power consumption is described as device 3 (target device 31) without distinguishing whether it is a branch circuit or individual device 3 (target device 31).
　見守り通知装置１０は、計測装置３０が計測した（単位時間当たりの）消費電力量を取得する取得部１１を備える。取得部１１は、計測装置３０が計測するすべての機器３について消費電力量を取得するよう構成されていてもよい。ただし、対象者を見守るためには、すべての機器３について消費電力量を取得する必要はない。また、対象者を見守るために必要な機器３（対象機器３１）は、住宅４０によって異なる。そのため、見守り通知装置１０は、着目する機器（対象機器）３１を選択できるように設定部１５を備えている。つまり、取得部１１は、設定部１５で設定された（少なくとも一つの）対象機器３１のみの消費電力量を、計測装置３０から取得する。 The watching notification device 10 includes an acquisition unit 11 that acquires the power consumption (per unit time) measured by the measurement device 30. The acquisition unit 11 may be configured to acquire the power consumption for all the devices 3 measured by the measurement device 30. However, in order to watch over the target person, it is not necessary to acquire the power consumption amount for all the devices 3. Further, the device 3 (target device 31) necessary for watching the target person differs depending on the house 40. Therefore, the watching notification device 10 includes a setting unit 15 so that a device (target device) 31 of interest can be selected. That is, the acquisition unit 11 acquires the power consumption amount of only the (at least one) target device 31 set by the setting unit 15 from the measurement device 30.
　設定部１５は、対象機器３１として選択可能な機器３の選択肢を、後述する表示装置２０１に表示させることが望ましい。機器３の選択肢は、たとえば、表示装置２０１が有するタッチパネルスクリーン上に、仮想的なボタンなどの形で表示される。たとえば、表示装置２０１に表示された選択肢は、利用者が操作装置２０２を操作することにより選択される。表示装置２０１に表示する選択肢は、利用者にとってわかりやすくなるように、部屋名あるいは機器名を用いて特定することが望ましい。また、設定部１５は、住宅４０の全体を選択肢に含めてもよい。住宅４０の全体が対象機器３１として選択された場合、たとえば、取得部１１は、対象者が生活する対象空間（住宅４０）で使用されるすべての機器３による資源の消費量（消費電力量）の、総量を取得するよう構成される。 It is desirable that the setting unit 15 displays the options of the device 3 that can be selected as the target device 31 on the display device 201 described later. For example, the options of the device 3 are displayed in the form of virtual buttons or the like on the touch panel screen of the display device 201. For example, the option displayed on the display device 201 is selected when the user operates the operation device 202. The options displayed on the display device 201 are preferably specified using a room name or a device name so as to be easily understood by the user. The setting unit 15 may include the entire house 40 as an option. When the entire house 40 is selected as the target device 31, for example, the acquisition unit 11 consumes resources (power consumption) by all the devices 3 used in the target space (house 40) where the target person lives. Configured to obtain a total amount.
　なお、取得部１１が消費電力量を取得する対象機器３１の数が増加すると、見守り通知装置１０の処理負荷が増大するから、設定部１５により選択可能な選択肢の最大数は、たとえば、４程度に制限されていることが望ましい。いま、分岐回路が部屋を単位として割り当てられている場合を想定する。この場合、利用者による操作装置２０２の操作に応じて、設定部１５により、たとえば、「キッチン」「リビング」「寝室」「洗面所・トイレ」の４種類が選択される。 Note that, when the number of target devices 31 from which the acquisition unit 11 acquires power consumption increases, the processing load of the watch notification device 10 increases. Therefore, the maximum number of options that can be selected by the setting unit 15 is, for example, about 4 It is desirable to be limited to Assume that the branch circuit is assigned in units of rooms. In this case, according to the operation of the operation device 202 by the user, for example, four types of “kitchen”, “living room”, “bedroom”, and “toilet / toilet” are selected by the setting unit 15.
　取得部１１が取得した対象機器３１の各々の単位時間当たりの消費電力量は、時計部１６が計時する日時と併せて記憶部１７に格納される。記憶部１７には、対象機器３１の各々の消費電力量の変動が、所定の期間を１サイクルとして格納される。記憶部１７に格納する消費電力量は、ここでは１日を単位（１サイクル）とする場合を想定している。たとえば、対象機器３１の各々について、単位時間（たとえば１時間）当たりの消費電力量が、０時から次の日の０時までの期間を１サイクルとして、記憶部１７に格納される。ただし、１日を複数の時間帯ごとの期間に分割することも可能である。１日を複数の期間に分割する場合、個々の期間の長さは等しくなくてもよい。要するに、対象者の住宅４０での日々の生活において、消費電力量の変化に周期性ないし習慣性が見出される対象機器３１に着目し、この周期性ないし習慣性を抽出できるように期間が設定されていればよい。また、平日と休日とでは消費電力量の変化が異なる可能性が高いため、平日と休日との消費電力量を区別して記憶部１７に格納可能に構成されていることが望ましい。 The power consumption per unit time of the target device 31 acquired by the acquisition unit 11 is stored in the storage unit 17 together with the date and time counted by the clock unit 16. The storage unit 17 stores the variation of the power consumption amount of each target device 31 with a predetermined period as one cycle. Here, the power consumption stored in the storage unit 17 is assumed to be a unit (one cycle) of one day. For example, for each target device 31, the power consumption per unit time (for example, 1 hour) is stored in the storage unit 17 with a period from 0:00 to 0:00 on the next day as one cycle. However, it is also possible to divide a day into periods for a plurality of time zones. When dividing one day into a plurality of periods, the lengths of the individual periods may not be equal. In short, in the daily life of the target person's house 40, the period is set so that the periodicity or habituality can be extracted by paying attention to the target device 31 in which the periodicity or habituality is found in the change in power consumption. It only has to be. Further, since there is a high possibility that the change in power consumption differs between weekdays and holidays, it is desirable that the power consumption amounts between weekdays and holidays can be distinguished and stored in the storage unit 17.
　以下の構成例では、１日について１時間ごとに電力量を取得し、記憶部１７が少なくとも１週間分の電力量を記憶する場合を想定する。つまり、記憶部１７は、１日あたり２４個のデータ（消費電力量）を記憶し、１週間では１６８個のデータを記憶することになる。 In the following configuration example, it is assumed that the power amount is acquired every hour for one day, and the storage unit 17 stores the power amount for at least one week. That is, the storage unit 17 stores 24 data (power consumption amount) per day, and stores 168 data in one week.
　ところで、見守りの対象者について異常が生じているか否かは、対象者の平時における行動との比較によって検出される。このために見守り通知装置１０は、参照部１８を備える。参照部１８は、着目する機器（対象機器３１）に関し、平時における消費電力量の推移を記憶部１７から抽出し、対象者に異常が生じているか否かを判断するための基準になる第１の消費量を生成して記憶する。 By the way, whether or not an abnormality has occurred in the monitoring target person is detected by comparison with the behavior of the target person in normal times. For this purpose, the watch notification device 10 includes a reference unit 18. The reference unit 18 extracts a transition of power consumption during normal times from the storage unit 17 with respect to the device of interest (target device 31), and serves as a reference for determining whether an abnormality has occurred in the subject. Generate and store the amount of consumption.
　第１の消費量は、たとえば、記憶部１７が記憶している過去の数日分について開始時刻が等しい単位時間ごとの消費電力量を平均した値を、それぞれの単位時間の消費電力量の値とする。たとえば、第１の消費量における午前８時から９時までの１時間の消費電力量は、月曜日から金曜日までの５日間における午前８時から９時までの１時間の消費電力量の平均値を割り当てるのである。 The first consumption amount is, for example, a value obtained by averaging power consumption amounts for each unit time having the same start time for the past several days stored in the storage unit 17, and a value of the power consumption amount for each unit time. And For example, the power consumption for one hour from 8:00 am to 9:00 am in the first consumption is the average value of the power consumption for one hour from 8:00 am to 9:00 am on five days from Monday to Friday. Assign.
　たとえば、参照部１８が記憶する第１の消費量は、所定のタイミングで更新される。一例において参照部１８は、単位時間（本例では１時間）が経過するごとに、第１の消費量を更新する。別例において参照部１８は、記憶部１７に格納される消費電力量の１サイクルが経過するごとに、第１の消費量を更新する。たとえば、記憶部１７が、１日を単位（１サイクル）として消費電力量を格納している場合、参照部１８は、毎日の０時に第１の消費量を更新する。 For example, the first consumption amount stored in the reference unit 18 is updated at a predetermined timing. In one example, the reference unit 18 updates the first consumption every time a unit time (1 hour in this example) elapses. In another example, the reference unit 18 updates the first consumption every time one cycle of the power consumption stored in the storage unit 17 elapses. For example, when the storage unit 17 stores the power consumption in units of one day (one cycle), the reference unit 18 updates the first consumption at 0:00 every day.
　第１の消費量は、単位時間ごとの数日分の平均値を用いる代わりに、単位時間ごとに数日分の中の最大値あるいは最小値を用いることも可能である。また、第１の消費量は、単位時間ごとの消費電力量でなくてもよい。たとえば、１日を３～４区間に分割し、区間ごとに求めた消費電力量の合計値を第１の消費量として用いることが可能であり、また、１日の消費電力量の合計値を第１の消費量として用いることも可能である。さらにまた、これらの値を組み合わせて第１の消費量とすることも可能である。なお、第１の消費量は、設定部１５で設定された特定の機器（対象機器３１）について求めればよいが、すべての機器３について第１の消費量を求めてもよい。 For the first consumption, instead of using the average value for several days per unit time, it is possible to use the maximum value or the minimum value for several days per unit time. Further, the first consumption amount may not be the power consumption amount per unit time. For example, it is possible to divide a day into 3 to 4 sections, and use the total value of power consumption obtained for each section as the first consumption. It can also be used as the first consumption. Furthermore, it is possible to combine these values into the first consumption amount. The first consumption may be obtained for a specific device (target device 31) set by the setting unit 15, but the first consumption may be obtained for all devices 3.
　評価部１２は、取得部１１が取得した最新の消費電力量である第２の消費量を、参照部１８が記憶している第１の消費量と比較し、第２の消費量と第１の消費量との差異を評価する。つまり、評価部１２は、対象者の行動が平時と同様であるか、あるいは平時とは異なるかの評価を行う。ここで、設定部１５によって、対象者の生活を反映しやすい機器３が対象機器３１として選択されていれば、対象者が正常に生活していない場合（つまり、対象者に何らかの異常が生じている場合）、平時の消費電力量に対して差異が現れやすくなる。 The evaluation unit 12 compares the second consumption, which is the latest power consumption acquired by the acquisition unit 11, with the first consumption stored in the reference unit 18, and compares the second consumption with the first consumption. Evaluate the difference from the consumption. That is, the evaluation unit 12 evaluates whether the behavior of the target person is the same as that during normal time or different from normal time. Here, if the device 3 that easily reflects the life of the subject is selected as the subject device 31 by the setting unit 15, the subject does not live normally (that is, some abnormality occurs in the subject). A difference in power consumption during normal times is likely to appear.
　たとえば、設定部１５で選択されている対象機器３１のいずれかにおいて、当日のある時間帯における消費電力量が、平時の消費電力量に対して所定の基準値以上の差が生じていたとすると、評価部１２は、対象者に異常が生じている可能性があると評価する。あるいは、平時において時間の経過に伴って時間帯ごとに消費電力量が変化しているにもかかわらず、当日において時間が経過しても消費電力量が変化していない場合も同様に、評価部１２は、対象者に異常が生じている可能性があると評価する。 For example, in any of the target devices 31 selected by the setting unit 15, assuming that the power consumption in a certain time zone of the day is different from the normal power consumption by a predetermined reference value or more, The evaluation unit 12 evaluates that there is a possibility that the subject has an abnormality. Alternatively, when the power consumption changes for each time zone in the normal time with the passage of time, the evaluation unit similarly does not change the power consumption even if the time passes on the day. No. 12 evaluates that there is a possibility that the subject has an abnormality.
　第２の消費量と第１の消費量との差異は、第２の消費量と第１の消費量との距離（ユークリッド距離またはマンハッタン距離）による評価が可能である。この場合、第１の消費量と第２の消費量とについて、単位時間ごとあるいは区間ごとの差分を求め、この差分の合計を距離として用いればよい。具体的な距離の求め方は、ユークリッド距離かマンハッタン距離かに応じて異なるが、どちらの距離を用いるにしても、差異の程度を定量的に表すことができる。 The difference between the second consumption amount and the first consumption amount can be evaluated by the distance (Euclidean distance or Manhattan distance) between the second consumption amount and the first consumption amount. In this case, with respect to the first consumption amount and the second consumption amount, a difference for each unit time or for each section may be obtained and the sum of the differences may be used as the distance. The specific method of obtaining the distance differs depending on whether it is the Euclidean distance or the Manhattan distance, but regardless of which distance is used, the degree of the difference can be expressed quantitatively.
　評価部１２は、第２の消費量と第１の消費量との差異を段階的に評価してもよい。上述のように、差異の程度が定量的に表現されていれば、複数段階の閾値を用いることによって、差異を複数段階に分けることも可能である。 The evaluation unit 12 may evaluate the difference between the second consumption amount and the first consumption amount in a stepwise manner. As described above, if the degree of difference is expressed quantitatively, it is also possible to divide the difference into a plurality of stages by using a plurality of stages of threshold values.
　ここで、第２の消費量と第１の消費量との差異を距離のみによって評価すると、第２の消費量が第１の消費量に対して時間軸方向にシフトしている関係であっても、大きい差異と認識される可能性がある。この関係の場合、第２の消費量を第１の消費量に対して時間軸方向にシフトさせ、第２の消費量と第１の消費量とを重ね合わせると、第２の消費量と第１の消費量との差異が大幅に減少することが予想される。このような事象は、たとえば、対象者の起床が平時よりも遅いが、平時と同じ行動を行ったときに発生する。 Here, when the difference between the second consumption amount and the first consumption amount is evaluated based only on the distance, the second consumption amount is shifted in the time axis direction with respect to the first consumption amount. May be perceived as a large difference. In this case, when the second consumption is shifted in the time axis direction with respect to the first consumption and the second consumption and the first consumption are overlapped, the second consumption and the first consumption are overlapped. It is expected that the difference from the consumption of 1 will decrease significantly. Such an event occurs, for example, when the subject wakes up later than normal, but performs the same action as normal.
　そこで、評価部１２は、たとえば、第２の消費量（第２の変動パターン）の極大値の個数と第１の消費量（第１の変動パターン）の極大値の個数とが一致する場合（あるいは±１の誤差である場合）に、第２の消費量を第１の消費量との重複の程度が最大になるように時間軸方向に移動させることが望ましい。このように第２の消費量と第１の消費量とを時間軸方向において相対的に移動させた後は、評価部１２は、第２の消費量と第１の消費量との差異を距離によって評価すればよい。 Therefore, the evaluation unit 12, for example, when the number of maximum values of the second consumption (second variation pattern) matches the number of maximum values of the first consumption (first variation pattern) ( In the case of an error of ± 1), it is desirable to move the second consumption amount in the time axis direction so that the degree of overlap with the first consumption amount is maximized. After the second consumption amount and the first consumption amount are relatively moved in the time axis direction in this way, the evaluation unit 12 determines the difference between the second consumption amount and the first consumption amount as a distance. You may evaluate by.
　たとえば評価部１２は、第２の消費量に対応する時刻における第１の消費量を第１参照量とし、第２の消費量を第１参照量と比較して、第２の消費量と第１参照量との差の絶対値を第１差分値として求める。また評価部１２は、第２の消費量に対応する時刻から所定時間ずれた時刻（所定時間だけ前の時刻、または所定時間だけ後の時刻）における第１の消費量を第２参照量とし、第２の消費量を第２参照量と比較して、第２の消費量と第２参照量との差の絶対値を第２差分値として求める。評価部１２は、第１差分値と第２差分値とのうちの小さい方に基づいて、評価結果を生成する。 For example, the evaluation unit 12 sets the first consumption amount at the time corresponding to the second consumption amount as the first reference amount, compares the second consumption amount with the first reference amount, and compares the second consumption amount with the first consumption amount. An absolute value of a difference from one reference amount is obtained as a first difference value. In addition, the evaluation unit 12 sets the first consumption amount at a time (a time before a predetermined time or a time after a predetermined time) deviated by a predetermined time from a time corresponding to the second consumption as a second reference amount, The second consumption amount is compared with the second reference amount, and the absolute value of the difference between the second consumption amount and the second reference amount is obtained as the second difference value. The evaluation unit 12 generates an evaluation result based on the smaller one of the first difference value and the second difference value.
　なお評価部１２は、第１差分値と第２差分値とのうちの小さい方である比較対象値と予め決められた閾値とを比較し、得られた比較結果を評価結果として出力してもよい。また生成部１３は、比較対象値が閾値以下の場合は、対象者に異常がないことを示す報知情報を生成し、比較対象値が閾値よりも大きい場合は、対象者に異常があることを示す報知情報を生成してもよい。 Note that the evaluation unit 12 compares the comparison target value, which is the smaller one of the first difference value and the second difference value, with a predetermined threshold value, and outputs the obtained comparison result as the evaluation result. Good. Further, the generation unit 13 generates notification information indicating that there is no abnormality in the subject when the comparison target value is equal to or less than the threshold value, and indicates that the subject person is abnormal when the comparison target value is greater than the threshold value. The notification information shown may be generated.
　評価部１２は、複数の対象機器３１について消費電力量の差異を評価することが望ましい。つまり、設定部１５で複数の対象機器３１を選択することにより、取得部１１で複数の対象機器３１に関する消費電力量を取得するようにし、評価部１２では、複数の対象機器３１に関して第２の消費量の第１の消費量に対する差異を評価することが望ましい。 It is desirable that the evaluation unit 12 evaluates the difference in power consumption for a plurality of target devices 31. In other words, the setting unit 15 selects a plurality of target devices 31 so that the acquisition unit 11 acquires the power consumption related to the plurality of target devices 31, and the evaluation unit 12 performs the second operation on the plurality of target devices 31. It is desirable to evaluate the difference in consumption relative to the first consumption.
　設定部１５により複数の対象機器３１が選択されている場合、評価部１２は、複数の対象機器３１のうちのいずれかの使用状態が平時とは異なっていれば、対象者に異常が生じている可能性があると判断可能である。また、評価部１２は、複数の対象機器３１について抽出した消費電力量の変化を組み合わせることによって、対象者に生じている異常の種類を判断するようにしてもよい。 When a plurality of target devices 31 are selected by the setting unit 15, the evaluation unit 12 causes an abnormality in the target person if any of the usage states of the plurality of target devices 31 is different from the normal time. It is possible to judge that there is a possibility. In addition, the evaluation unit 12 may determine the type of abnormality occurring in the target person by combining changes in the power consumption extracted for the plurality of target devices 31.
　また、評価部１２は、着目する複数の対象機器３１について、対象機器３１ごとに求めた消費電力量を用い、消費電力量の組み合わせによって緊急度を設定することが望ましい。たとえば、差異（距離）が閾値以上である対象機器３１の台数が多いほど緊急度を高く設定すれば、平時とは異なる行動が多く生じているほど緊急度が高くなる。 In addition, it is desirable that the evaluation unit 12 sets the urgency level by using the power consumption obtained for each target device 31 for a plurality of target devices 31 to which attention is paid, and by combining the power consumption. For example, if the urgency level is set higher as the number of target devices 31 having a difference (distance) equal to or greater than a threshold value increases, the urgency level increases as more actions different from normal times occur.
　さらに、該当する対象機器３１に関して平時の極大値あるいは極小値との差が所定範囲内であっても、電力量が複数の時間帯に跨がってほとんど変化していなければ、対象者が対象機器３１を操作していない可能性がある。このような場合、評価部１２は、対象者の状態を異常の可能性があると評価する。この評価を行うために、評価部１２には、着目する対象機器３１について消費電力量の上限値および下限値が設定される。評価部１２は、消費電力量が上限値以上である状態あるいは消費電力量が下限値以下である状態が、あらかじめ定めた時間を超えて継続しているときに、対象者に異常が生じている可能性があると評価し、緊急度を高くする。 Furthermore, even if the difference between the maximum value or the minimum value during normal time for the target device 31 is within a predetermined range, if the amount of power hardly changes over a plurality of time zones, the target person is the target. The device 31 may not be operated. In such a case, the evaluation unit 12 evaluates that the subject's state is likely to be abnormal. In order to perform this evaluation, the evaluation unit 12 is set with an upper limit value and a lower limit value of the power consumption for the target device 31 of interest. The evaluation unit 12 has an abnormality in the subject when the state where the power consumption is equal to or higher than the upper limit value or the state where the power consumption amount is equal to or lower than the lower limit value continues for a predetermined time. Assess potential and increase urgency.
　評価部１２が対象者について評価した結果は生成部１３に与えられ、生成部１３は、評価部１２の評価結果に応じて異なる内容の報知情報を生成する。報知情報は、報知装置２０に報知するメッセージの内容の情報と、報知装置２０の管理者が対象者に連絡する場合の連絡の方法である連絡情報と、報知装置２０に報知するタイミングと、評価部１２が評価した緊急度とから選択される情報を含む。つまり、生成部１３は、これらの情報の少なくとも１種類について、評価部１２の評価結果に応じて異なる内容の報知情報を生成する。 The result of the evaluation unit 12 evaluating the subject is given to the generation unit 13, and the generation unit 13 generates notification information having different contents according to the evaluation result of the evaluation unit 12. The notification information includes information on the content of a message to be notified to the notification device 20, contact information that is a communication method when the administrator of the notification device 20 contacts the subject, timing to notify the notification device 20, and evaluation. The information selected from the urgency evaluated by the unit 12 is included. That is, the generation unit 13 generates notification information with different contents according to the evaluation result of the evaluation unit 12 for at least one of these pieces of information.
　たとえば評価部１２は、第１の閾値と、第１の閾値よりも大きな第２の閾値とを有する。評価部１２は、第１の消費量（対象機器３１について取得部１１が取得した平時の資源の消費量）と第２の消費量（対象機器３１について取得部１１が取得した最新の資源の消費量）との差分の絶対値が、第１の閾値以下である場合、生成部１３に第１の評価結果を出力する。評価部１２は。第１の消費量と第２の消費量との差分の絶対値が、第１の閾値よりも大きく且つ所定の第２の閾値以下である場合、生成部１３に第２の評価結果を出力する。評価部１２は、第１の消費量と第２の消費量との差分の絶対値が、第２の閾値よりも大きい場合、生成部１３に第３の評価結果を出力する。 For example, the evaluation unit 12 has a first threshold value and a second threshold value that is larger than the first threshold value. The evaluation unit 12 uses the first consumption (consumption of normal resources acquired by the acquisition unit 11 for the target device 31) and the second consumption (consumption of the latest resources acquired by the acquisition unit 11 for the target device 31). When the absolute value of the difference from the (quantity) is equal to or less than the first threshold value, the first evaluation result is output to the generation unit 13. Evaluation unit 12. When the absolute value of the difference between the first consumption amount and the second consumption amount is greater than the first threshold value and less than or equal to the predetermined second threshold value, the second evaluation result is output to the generation unit 13. . The evaluation unit 12 outputs the third evaluation result to the generation unit 13 when the absolute value of the difference between the first consumption amount and the second consumption amount is larger than the second threshold value.
　たとえば生成部１３は、評価部１２から第１の評価結果を受け取ると、見守り対象者に異常がないことを示す報知情報を生成する。この報知情報は、たとえば、予め定められた時刻に、報知装置２０に通知される。 For example, when the generation unit 13 receives the first evaluation result from the evaluation unit 12, the generation unit 13 generates notification information indicating that there is no abnormality in the watching target person. This notification information is notified to the notification device 20, for example, at a predetermined time.
　たとえば生成部１３は、評価部１２から第２の評価結果を受け取ると、見守り対象者に異常の兆候があることを示す報知情報を生成する。この報知情報は、たとえば、予め定められた時刻に、報知装置２０に通知される。 For example, when the generation unit 13 receives the second evaluation result from the evaluation unit 12, the generation unit 13 generates notification information indicating that the person to be watched has an abnormality sign. This notification information is notified to the notification device 20, for example, at a predetermined time.
　たとえば生成部１３は、評価部１２から第３の評価結果を受け取ると、見守り対象者に異常があることを示す報知情報を生成する。この報知情報は、たとえば、生成部１３が報知情報を生成した時点で即座に報知装置２０に通知される。 For example, when the generation unit 13 receives the third evaluation result from the evaluation unit 12, the generation unit 13 generates notification information indicating that the watching target person has an abnormality. For example, the notification information is immediately notified to the notification device 20 when the generation unit 13 generates the notification information.
　生成部１３が生成した報知情報は、通信部１４を通して、あらかじめ登録されている報知装置２０に送信される。報知装置２０は、たとえば、見守りの対象者の家族が管理している。たとえば、住宅４０に高齢の親が住んでいる場合に、親の状態を子供が見守るために報知装置２０が用いられる。通信部１４は、毎日定められた時刻に報知情報を報知装置２０に通知する定時通知と、報知情報が確定した時点で報知情報を報知装置２０に通知する即時通知との動作が可能である。定時通知を行う時刻は、後述するように、あらかじめ通信部１４に設定される。また、即時通知を行うタイミングは、生成部１３が生成した報知情報の内容に従う。 The notification information generated by the generation unit 13 is transmitted to the notification device 20 registered in advance through the communication unit 14. The notification device 20 is managed, for example, by the family of the person being watched over. For example, when an elderly parent lives in the house 40, the notification device 20 is used for the child to watch the state of the parent. The communication unit 14 can operate as a scheduled notification that notifies the notification device 20 of the notification information at a predetermined time every day and an immediate notification that notifies the notification device 20 of the notification information when the notification information is determined. The time for performing the scheduled notification is set in the communication unit 14 in advance, as will be described later. Further, the timing for immediate notification follows the content of the notification information generated by the generation unit 13.
　ここでは、スマートフォンを報知装置２０に用いた場合の画面例を図２～図９に示す。見守り通知装置１０から報知装置２０へは、プッシュ方式で報知情報が送信される。 Here, FIGS. 2 to 9 show examples of screens when a smartphone is used for the notification device 20. Notification information is transmitted from the watch notification device 10 to the notification device 20 by a push method.
　図２は評価部１２が対象者に異常がないと評価した場合の報知情報を、通信部１４が定時通知で報知装置２０であるスマートフォンに送信した場合の画面である。図示例は、報知情報の受信に伴って、報知装置２０の画面上にウインドウＡ１がポップアップした状態を示している。ウインドウＡ１には、報知情報に従って、「おおむねいつも通り電力を使用しています」というメッセージが表示されている。つまり、対象者に異常がない可能性が高いことを示している。 FIG. 2 is a screen when the communication unit 14 transmits the notification information when the evaluation unit 12 evaluates that the subject person has no abnormality to the smartphone that is the notification device 20 by the regular notification. The illustrated example shows a state where the window A1 pops up on the screen of the notification device 20 with the reception of the notification information. In the window A1, a message “usually using power as usual” is displayed according to the notification information. That is, there is a high possibility that the subject has no abnormality.
　図３はスマートフォンを報知装置２０として機能させるためのアプリケーションプログラム（いわゆる「アプリ」）を起動した時点の画面例を示している。この動作も、図２に示した動作例と同様に、報知情報を受け取り、「おおむねいつも通り電力を使用しています」というメッセージが表示されている。ここでは、図２に示したウインドウＡ１とは異なる形状のウインドウＣ１が表示されている。また、図３には、対象者の住宅を選択するための矢羽根状の選択釦Ｂ１が表示されている。選択釦Ｂ１の向きに指をスライドさせると対象となる住宅４０が切り替えられる。なお、選択中の住宅４０は選択釦Ｂ１に隣接する領域に表示される（図示例では、「○○家」と示している）。 FIG. 3 shows an example of a screen when an application program (so-called “app”) for causing a smartphone to function as the notification device 20 is started. In this operation, similar to the operation example shown in FIG. 2, the notification information is received, and a message “usually using power as usual” is displayed. Here, a window C1 having a different shape from the window A1 shown in FIG. 2 is displayed. FIG. 3 also shows an arrow feather-shaped selection button B1 for selecting the subject's house. When the finger is slid in the direction of the selection button B1, the target house 40 is switched. Note that the house 40 being selected is displayed in an area adjacent to the selection button B1 (in the example shown, “XX house”).
　ところで、報知装置２０を通して報知情報を受け取った報知装置２０の管理者は、図２あるいは図３の例のように、対象者に問題がなければ、対象者に連絡する必要はないが、多少でも対象者に異常が生じた場合には、対象者の状態を確認する必要がある。対象者の異常は、消費電力量の推移に基づいているから、対象者の生活状態に異常が生じているとは限らないが、確認のために対象者に連絡して確認をとることが望まれる。ここで、報知装置２０はスマートフォンを用いているから、電話、電子メールなどの連絡装置２０３（図１参照）を備えており、管理者は、これらの連絡装置２０３を用いて対象者に連絡することが可能である。 By the way, the administrator of the notification device 20 that has received the notification information through the notification device 20 does not need to contact the subject person as long as there is no problem with the subject as in the example of FIG. 2 or FIG. When an abnormality occurs in the subject, it is necessary to check the state of the subject. Since the abnormality of the subject is based on the transition of power consumption, the subject's life status is not necessarily abnormal, but it is desirable to contact the subject for confirmation. It is. Here, since the notification device 20 uses a smartphone, the notification device 20 includes a communication device 203 (see FIG. 1) such as a telephone and an e-mail, and the administrator uses these communication devices 203 to contact the target person. It is possible.
　そこで、評価部１２が、対象者が正常ではないと評価した場合、たとえば、図４に示すようなウインドウＣ３をポップアップさせることが望ましい。ウインドウＣ３には、「長い時間、電力値に変動がありません」というメッセージが表示されている。このウインドウＣ３は、単位時間当たりの消費電力量が上限値以上あるいは下限値以下である状態が、定めた時間を超えて継続している場合に生成部１３で生成される報知情報に基づいて表示される。また、この報知情報には、報知装置２０の管理者から対象者に連絡する方法を表す連絡情報が含まれる。つまり、図４に示すように、ウインドウＣ３の中に、連絡の方法として、「電話する」の操作釦Ｂ２と、「メールする」の操作釦Ｂ３とが表示され、いずれかの操作釦Ｂ２，Ｂ３を押すことによって、電話あるいは電子メールに対応した画面が表示される。ここに電話の画面では、電話番号が事前に登録されていれば、該当する電話番号に誘導され、電子メールの画面では、メールアドレスが事前に登録されていれば、該当するメールアドレスがセットされた状態で電子メール用のプログラムが起動される。 Therefore, when the evaluation unit 12 evaluates that the subject is not normal, for example, it is desirable to pop up a window C3 as shown in FIG. In the window C3, a message “There is no fluctuation in the power value for a long time” is displayed. This window C3 is displayed based on the notification information generated by the generation unit 13 when the state where the power consumption per unit time is equal to or higher than the upper limit value or lower than the lower limit value continues for a predetermined time. Is done. Further, the notification information includes contact information indicating a method for contacting the subject person from the administrator of the notification device 20. That is, as shown in FIG. 4, as a contact method, an operation button B2 for “telephone” and an operation button B3 for “email” are displayed in the window C3. By pressing B3, a screen corresponding to a telephone or e-mail is displayed. Here, if the phone number is registered in advance on the phone screen, it will be directed to the corresponding phone number, and if the email address is registered in advance on the email screen, the corresponding email address will be set. In this state, the e-mail program is started.
　このように連絡方法を示す画面が報知装置２０の表示装置２０１に表示されることによって、報知装置２０の管理者は対象者への連絡が促される。そのため、対象者の生活状態に異常が生じている可能性がある場合に、報知装置２０の管理者にとっては対象者に連絡する契機が与えられることになり、対象者の生活状態を怠りなく確認することになる。 As described above, the screen indicating the contact method is displayed on the display device 201 of the notification device 20, whereby the administrator of the notification device 20 is prompted to contact the target person. Therefore, when there is a possibility that an abnormality has occurred in the living state of the subject person, the administrator of the notification device 20 will be given an opportunity to contact the subject person, and the living state of the subject person will be confirmed without delay. Will do.
　定時通知において、報知装置２０における表示装置２０１の画面にポップアップされるウインドウＣ１～Ｃ３の例を図５（ａ）～（ｃ）に示し、即時通知において、ポップアップされるウインドウＣ４の例を図５（ｄ）に示す。図５（ａ）の例は図３に示した例と同様であり、図５（ｃ）の例は図４に示した例と同様である。 FIGS. 5A to 5C show examples of windows C1 to C3 popped up on the screen of the display device 201 in the notification device 20, and FIG. 5 shows an example of the window C4 popped up in the immediate notification. Shown in (d). The example of FIG. 5A is the same as the example shown in FIG. 3, and the example of FIG. 5C is the same as the example shown in FIG.
　図５（ｂ）の例は、評価部１２の評価結果が、対象者は正常ではないという評価結果であるが、図５（ｃ）の例と比較すると、緊急度が低い状態を示している。つまり、単位時間当たりの消費電力量は変化しているから、対象者が生活行動を行っていることは認められるが、平時と比較すると消費電力量が少なく、対象者の行動量が平時よりも少なく、たとえば、寝込んでいる可能性が考えられる状態を示している。このような場合に、報知装置２０のウインドウＣ２には、「今日はあまり電力を使用していないようです」などのメッセージが表示され、さらに、連絡方法を示す操作釦Ｂ２，Ｂ３が表示される。 The example of FIG. 5B is an evaluation result that the evaluation unit 12 evaluates that the subject is not normal, but shows a state of low urgency compared to the example of FIG. 5C. . In other words, since the amount of power consumption per unit time has changed, it is recognized that the subject is performing living activities, but the amount of power consumption is less than normal, and the amount of behavior of the subject is lower than normal. For example, it shows a state where there is a possibility that the user is asleep. In such a case, a message such as “It seems that electricity is not used much today” is displayed in the window C2 of the notification device 20, and operation buttons B2 and B3 indicating a contact method are further displayed. .
　図５（ｂ）のウインドウＣ２と、図５（ｃ）のウインドウＣ３とでは、メッセージの内容が異なるだけではなく、緊急度の違いを示すマークが表示されるか否かの違いがある。図５（ｃ）の状態は、図５（ｂ）の状態よりも緊急度が高いと考えられるから、図５（ｃ）のウインドウＣ３には、三角形の中に感嘆符を表記したマークが表示されている。このマークは、たとえば、黄色などの色を付与しておけば、報知装置２０の管理者に緊急度の高さを示すことができる。 In the window C2 in FIG. 5B and the window C3 in FIG. 5C, not only the content of the message is different, but also there is a difference in whether or not a mark indicating a difference in urgency is displayed. Since the state of FIG. 5C is considered to be more urgent than the state of FIG. 5B, a mark indicating an exclamation mark in a triangle is displayed in the window C3 of FIG. 5C. Has been. If this mark is given a color such as yellow, for example, the manager of the notification device 20 can be shown a high degree of urgency.
　図５（ｄ）は即時通知のウインドウＣ４の例であり、実質的には図５（ｃ）に示した例と同様である。たとえば、図５（ｄ）のウインドウＣ４は、単位時間当たりの消費電力量が上限値以上あるいは下限値以下である状態が継続している場合に表示される。ウインドウＣ４に表記されたメッセージおよびマークも同様に表示される。ただし、ウインドウＣ４の中に電子メールの操作釦Ｂ３は表示されず、電話用の操作釦Ｂ２のみが表示される。マークは、たとえば、赤色などの色が付与され、緊急度の高さが示される。図５（ｄ）において連絡方法の操作釦Ｂ２が電話のみであるのは、電子メールでは即時性がないからである。 FIG. 5 (d) is an example of the immediate notification window C4, which is substantially the same as the example shown in FIG. 5 (c). For example, the window C4 in FIG. 5D is displayed when the state where the power consumption per unit time is equal to or higher than the upper limit value or lower than the lower limit value continues. Messages and marks written in the window C4 are also displayed in the same manner. However, the e-mail operation button B3 is not displayed in the window C4, and only the telephone operation button B2 is displayed. The mark is given a color such as red, for example, and indicates a high degree of urgency. The reason why the operation method button B2 for the contact method is only a telephone in FIG. 5D is that there is no immediacy in electronic mail.
　なお、図５（ｃ）のウインドウＣ３が表示されるか、図５（ｄ）のウインドウＣ４が表示されるかは、評価部１２が評価する緊急度による。たとえば、評価部１２は、上述したように複数の対象機器３１について消費電力量を評価する場合において、消費電力量が平時の消費量とは異なる対象機器３１の個数（正常ではない対象機器３１の個数）が多いほど緊急度を高くする。この場合、生成部１３は、正常ではない対象機器３１の個数（評価部１２が評価した緊急度）に応じて、図５（ｃ）のウインドウＣ３と図５（ｄ）のウインドウＣ４とのいずれか一方を選択する。なお、正常ではない対象機器３１の個数ではなく、特定の対象機器３１が正常ではないと評価された場合に、図５（ｄ）のウインドウＣ４を表示するようにしてもよい。 Whether the window C3 in FIG. 5C or the window C4 in FIG. 5D is displayed depends on the degree of urgency evaluated by the evaluation unit 12. For example, in the case where the evaluation unit 12 evaluates the power consumption for a plurality of target devices 31 as described above, the number of target devices 31 whose power consumption is different from the normal consumption (the number of target devices 31 that are not normal). The greater the number), the higher the urgency. In this case, the generation unit 13 selects either the window C3 in FIG. 5C or the window C4 in FIG. 5D depending on the number of target devices 31 that are not normal (the urgency level evaluated by the evaluation unit 12). Select either one. Note that the window C4 in FIG. 5D may be displayed when it is evaluated that the specific target device 31 is not normal, not the number of target devices 31 that are not normal.
　ところで、定時通知を行う時刻は、報知装置２０を見守り通知装置１０の操作器として用いることによって、設定することが可能である。つまり、見守り通知装置１０における種々の設定は、見守り通知装置１０に付設した表示器および操作器を用いて対話的に行うことが可能であるが、これらの表示器および操作器の機能を、報知装置２０で代用することが可能である。 By the way, the time for performing the scheduled notification can be set by watching the notification device 20 and using it as an operating device of the notification device 10. In other words, various settings in the watch notification device 10 can be interactively performed using the display device and the operation device attached to the watch notification device 10, but the functions of these display device and operation device are notified. A device 20 can be substituted.
　図６は、定時通知の時刻を報知装置２０から指定した例であって、７：００と２１：００とに見守り通知装置１０から報知装置２０に定時通知が行われることを示している。図示する２つの時刻には、それぞれオンとオフとを選択するスイッチＢ４が対応付けられており、スイッチＢ４でオンを選択した時刻に定時通知が行われるようになっている。なお、定時通知の時刻の変更および追加が可能になっている。なお、定時通知の時刻と同様に、見守り通知装置１０において対象機器３１を選択するための設定部１５も、報知装置２０で操作できるようにしておくことが望ましい。 FIG. 6 is an example in which the time of the scheduled notification is designated from the notification device 20, and shows that the scheduled notification is performed from the watch notification device 10 to the notification device 20 at 7:00 and 21:00. The two times shown in the figure are associated with a switch B4 for selecting ON and OFF, respectively, and a scheduled notification is performed at the time when ON is selected by the switch B4. Note that it is possible to change and add the scheduled notification time. In addition, it is desirable that the setting unit 15 for selecting the target device 31 in the watch notification device 10 can be operated by the notification device 20 in the same way as the time of the scheduled notification.
　図７に示す画面は、定時通知および即時通知に関する履歴を表示するウインドウＥ１の例であって、過去数日分の報知情報の内容が一覧できるように表示される。また、この画面においてスクロールを行えば、さらに前の報知情報の内容も確認可能である。 The screen shown in FIG. 7 is an example of a window E1 that displays a history regarding scheduled notifications and immediate notifications, and is displayed so that the contents of notification information for the past several days can be listed. In addition, if scrolling is performed on this screen, the content of the previous notification information can be confirmed.
　図８に示す画面は、過去数日分の住宅４０全体における消費電力量の推移を示している。このような表示を可能にすることによって、ここ数日間に消費電力量の推移に変化が生じているか否かを、簡単に読み取ることができる。つまり、前日までは評価部１２での評価が正常であったとすると、前日までは平時における消費電力量の推移Ｄ２を示すことになる。報知装置２０の管理者は、この推移Ｄ２を当日の消費電力量の推移Ｄ１と比較することによって、消費電力量についてどのような異常が生じているのかを容易に識別することが可能になる。なお、図７、図８に示した情報は、見守り通知装置１０あるいは報知装置２０で保持することが可能であるが、別に設けたサーバあるいはクラウドサーバに保持しておいてもよい。 The screen shown in FIG. 8 shows the transition of power consumption in the entire house 40 for the past several days. By making such a display possible, it is possible to easily read whether or not there has been a change in the transition of power consumption over the past few days. That is, if the evaluation by the evaluation unit 12 is normal until the previous day, the transition D2 of the power consumption during normal time is indicated until the previous day. The administrator of the notification device 20 can easily identify what kind of abnormality has occurred in the power consumption amount by comparing the transition D2 with the power consumption amount transition D1 of the day. The information shown in FIGS. 7 and 8 can be held by the watch notification device 10 or the notification device 20, but may be held in a separate server or cloud server.
　図９に示す例は、設定部１５で選択した対象機器３１（分岐回路）ごとの１日における消費電力量の推移を一覧にして示す画面であって、このような画面を表示することにより、対象者の行動をある程度把握することが可能になる。 The example shown in FIG. 9 is a screen showing a list of changes in power consumption per day for each target device 31 (branch circuit) selected by the setting unit 15. By displaying such a screen, It becomes possible to grasp the behavior of the target person to some extent.
