【0004】
【発明が解決しようとする課題】
しかしながら、前記トイレや玄関等の扉の開閉等は、生活パターンの中でも比較的傾向のばらつきが大きい要素であり、基準パターンとの比較で居住者の体調の良否を判断するには正確さに欠ける面がある。また、照明器具等の操作内容は、比較的ばらつきの少ない要素ではあるものの、当該操作内容を取得するには、電源の調達など別途操作内容を取得する為の設備が必要となる。仮に光センサを用いて照明の使用を検出するとしても、屋外からの光など外乱の影響を受けやすいという欠点もある。また、更に多くのセンサを設置して判断の正確さを期そうとすれば、今度は、それらを運用するための設備や処理内容も多くなりコスト的な問題が浮上する。
【0005】
本発明は、上記実情に鑑みてなされたものであって、統計的にパターンのばらつきが比較的少なく、別途付属的な設備工事を必要とせず、且つ外乱の影響を受けにくい低コストな冷蔵庫の扉開閉感知用伝送端末装置及び生活モニターシステムの提供を目的とする。
【0006】
【課題を解決するための手段】
上記課題を解決するために為された本発明による冷蔵庫の扉開閉感知用伝送端末装置は、電源部、伝送部、及び検出部から構成され、前記電源部は、電力供給源からの交流起電力を直流に変換する整流回路、及び直流化された起電力を二次電池に蓄えそれを放電する為の充放電回路とを備え、前記伝送部は、冷蔵庫の扉を開閉した旨の信号供給源たる前記検出部からの信号を受けて当該伝送端末装置のIDデータを無線信号として送出する送信回路を備え、前記検出部は、微細振動検出センサ及び衝撃振動検出センサを備え、前記微細振動検出センサにピエゾ素子が用いられていることを特徴とする。
【0007】
尚、上記微細振動検出センサ及び衝撃振動検出センサは、一個のセンサが兼用されていても良いし、別個のセンサが用いられていても良い。前記微細振動検出センサとしてピエゾ素子を用いるとしているが、前記衝撃振動検出センサにもピエゾ素子を用い得ることは言うまでもない。
【0008】
上記課題を解決するために為された本発明による生活モニターシステムは、冷蔵庫の扉の開閉を感知するセンサの稼働を示す稼働データを無線発信する伝送端末装置と、当該稼働データを受信し当該稼働データに基づき前記センサの一定期間毎の動作回数及びその動作時刻を冷蔵庫の扉開閉実績パターンとして保存するパターン保存手段、及び前記扉開閉実績パターンとあらかじめ保持している扉開閉基準パターンとを比較し居住者の体調を推定するパターン判定手段とを具備し前記推定結果が体調異常との判断である場合に予め定めた宛先へ発信する中継端末装置とから構成されることを特徴とする。
【0009】
尚、前記稼働データは、センサの稼働及び停止を認識できれば良く、“開”または“閉”のステータスを示すステータスデータでも良いし、“開から閉へ”或いは“閉から開へ”ステータスが変化した際のトリガーデータでも良い。
【0010】
また、前記伝送端末装置に、冷蔵庫に生じる振動を電気信号に変換する無線発信用電源を設けても良く、前記パターン保存手段によって保存された扉開閉実績パターンの統計を一定期間毎にとり、当該統計結果に基づいて前記扉開閉基準パターンを更新する基準更新手段を設けても良い。
【0011】
【発明の実施の形態】
以下、本発明による冷蔵庫を用いた生活モニターシステムの実施の形態を図面に基づき説明する。
当該例は、冷蔵庫10における扉の開閉を感知するセンサのステータスの変化を示す稼働データを無線発信する冷蔵庫取付用伝送端末装置(以下、伝送端末装置12と記す)と、当該稼働データを受信し当該稼働データに基づき前記センサの一定期間毎の動作回数及びその動作時刻を冷蔵庫10の扉開閉実績パターンとして各々保存するパターン保存手段14と、前記扉開閉実績パターンとあらかじめ保持している扉開閉基準パターンとを比較し居住者の体調を推定するパターン判定手段15とを具備し、前記推定結果が体調異常との判断である場合に予め定めた宛先へ発信する中継端末装置16とから構成されるシステムである(図1参照)。
【0012】
前記伝送端末装置12は、電源部1、伝送部2、及び検出部3から構成される。
前記電源部1は、電力供給源からの交流起電力を直流に変換する整流回路4、直流化された起電力を充放電可能なニッケル水素蓄電池等の二次電池5に蓄えそれを放電する為の充放電回路6とから構成され、前記伝送部2は、信号供給源からのパルス信号を伝送用のトリガー信号のレベルに増幅するアンプ回路13と、前記トリガー信号を受けて当該伝送端末装置12のIDデータを含む稼働データをFM無線信号として送出する送信回路7とから構成され、前記検出部3は、振動検出用のセンサ8,9によって構成される(図2及び図3参照)。
【0013】
当該例におけるセンサ8,9は、振動によって素子に加わる応力を電気エネルギーに変換するピエゾ素子の特性を採用したものである。ピエゾ素子にはピエゾセラミックが用いられる。センサ8,9として用いられたピエゾ素子は、冷蔵庫の稼働時において定常的に生じるサイン波状の微細振動や、扉の開閉に伴う比較的大きな衝撃振動による変形によって起電力を発生させる。ピエゾセラミックの形態としては、円盤状や棒状が一般的であるが、特に棒状のものは、比較的微細な応力に対する応答に優れていると言われ、冷蔵庫が恒常的に起こす振動を電力に変換して有効利用するのに適している。
【0014】
上記ピエゾ素子の起電力は、当該ピエゾ素子に設けられた対をなす端子が、図3の如く前記整流回路4にその出力を全波整流(半波整流でも可)する形で接続されることによって、当該センサ8,9を具備する前記伝送端末装置の前記電力供給源として機能し、又、無線発信用電源として機能する。また、例えば図5の如く、ピエゾ素子の両端子から直接引き出した出力によってFET等を駆動させ、定常状態の微細振動よりも比較的大きな衝撃振動によって生じるパルス信号を取り出せば、扉の開閉を示す稼働データとなるパルス信号源として機能する。
【0015】
前記センサ8,9は、前記伝送端末装置12の他の構成要素と共に筐体に収容されて、例えば図4(イ)の如く冷蔵庫10の本体(又は扉でも良い)に、筐体の裏面に貼着された磁石等の固定手段によって定着され、前記微細振動や比較的大きな衝撃振動を検出する。尚、これらを検出するセンサ8,9は異なるセンサとして個別に設けられていてもいいし、一つのセンサで共用しても良い。また、当該センサ8,9にあっても、前記伝送端末装置12の他の構成要素と共に筐体に収容されて一体化されていても良いし、前記伝送端末装置12の他の構成要素が収容された筐体からケーブル等を介して引き出されていても良い。その際は、別途センサの裏面にも磁石等の固定手段を設けることとなる。
【0016】
一方、前記中継端末装置16は、前記伝送端末装置12からの稼働データを受信する無線通信手段18と、当該稼働データに基づき前記センサのうちの衝撃振動検出センサ9の一定期間毎の動作回数及びその動作時刻を冷蔵庫10の扉開閉実績パターンとして保存するパターン保存手段14と、前記扉開閉実績パターンとあらかじめ保持している扉開閉基準パターンとを比較し居住者の体調を推定するパターン判定手段15と、前記パターン保存手段14によって保存された扉開閉実績パターンの統計を一定期間毎にとり、当該統計結果に基づいて前記扉開閉基準パターンを更新する基準更新手段17と、前記推定結果が体調異常との判断である場合に予め定めた宛先へ発信する通報手段19とを具備して構成される(図1(ロ)参照)。
【0017】
前記無線通信手段18、パターン保存手段14、パターン判定手段15、基準更新手段17、及び通報手段19は、当該伝送端末装置12のCPU回路から制御プログラムに基づいて発せられる制御コマンドによって制御される。前記稼働データは、前記無線通信手段18の通信インターフェース21及び通信制御部20を介して前記CPU回路によって監視され、例えば、前記伝送端末装置12から稼働データの受信があった際には、当該無線通信手段18によって立てられた受信フラグを以て前記CPU回路がその旨を認識し、当該稼働データをメモリ等へ保存するよう前記パターン保存手段14に促すこととなる。
【0018】
当該例においては、前記伝送端末装置12から冷蔵庫10の扉11の開閉それぞれのタイミングを示す稼働データとして送信されるので、前記パターン保存手段14は、当該稼働データを受けるたびに論理を反転させて保存すると共に、時計から当該論理が反転する際の時刻をメモリに保存する。この様にして、メモリ上に共通な時間軸をもった冷蔵庫10の扉11の開閉パターンが形成される。尚、扉11の開閉を検知する手法は、前記ピエゾ素子以外の、例えば図4(ロ)の如く、扉11の開閉状態を異なるステータスとして出力できるリミットスイッチ22等を用いることも出来る。
【0019】
上記扉の開閉パターンは、前記パターン保存手段14の機能によって、例えば一日といった一定の短期間毎に、単位時間帯毎に区切られた時間軸において、前記の如く扉の開閉が行われた時間をhigh/lowいずれかのステータスとする時系列のパターンとしてメモリに保存される。前記パターン判定手段15は、当該扉の開閉パターンを、あらかじめメモリ等に保持している同じ時間帯の扉開閉基準パターンと比較して採取された扉の開閉パターンの適否を示す判定データを形成する。
【0020】
前記扉開閉基準パターンは、例えば、基準更新手段17によって一週間といった一定の中・長期間毎に扉の開閉が行われた時間帯の統計をとり、前記扉の開閉パターンと同様に、単位時間帯毎に区切られた時間軸において一定の閾値以上に開閉の頻度が高い時間帯に扉の開閉が行われるという時系列の扉開閉基準パターン形成する。当該扉開閉基準パターンと日々の扉の開閉パターンとの比較の仕方としては、前記扉開閉基準パターンにおける扉の開放期間の中に日々の扉の開閉パターンにおける扉の開放期間が含まれていれば適正とするやり方が一例として挙げられる。また、一定の禁止要件を定めて判定基準に条件を加えても良い。
【0021】
前記パターン判定手段15によりその日の扉の開閉パターンが不適正と判定された場合には、前記CPU回路から前記通報手段19へ通報処理開始の制御コマンドが送られる。前記通報手段19としては、その通報制御部23によって前記制御コマンドを受けて当該システムの使用者に与えられたIDのデータ及び不適正と判定された扉の開閉パターンのパターンデータを例えばパケット化し、当該パケットデータを通報インターフェース24を介して別居家族や親類縁者宅、或いは携帯電話25など所定の通報先へ電話回線などの通信回線を通じて送信する等の形態が挙げられる(図1(イ)参照)。
【0022】
上記システムは、IDの異なる複数の前記伝送端末装置12を、例えば、図6の如く、冷凍室、冷蔵室、及び野菜室(冷蔵庫の態様に応じて設置)の前記各室用としてそれぞれの扉に固定し、前記中継端末装置16は、IDの異なる各伝送端末装置12から送信されてきた各室の扉の開閉状況たる稼働データを、前記パターン保存手段14によって個別にパターン化すると共に、IDの異なる各伝送端末装置12それぞれについて扉の開閉パターンを保存し、前記パターン判定手段15でそれぞれの扉開閉基準パターンと比較することによって、短期的、或いは中・長期的に用いられた食材や飲料を推定して偏った食癖や飲料の過剰摂取等の判断に用いることも可能であり、更に、異常と判断できる場合には前記の如く通報手段19を稼働して所定の通報先へその旨のデータ等を送信することもできる。
【0023】
【発明の効果】
以上の如く、本発明による冷蔵庫の扉開閉感知用伝送端末装置によれば、冷蔵庫の扉の開閉運動に伴う衝撃振動や、冷蔵庫自体の微振動をピエゾ素子によって電力に変換して稼働用電源として使用できるので、従来の様な一定期間毎の電池交換は不要となる。
【0024】
また、使用者の体調を推認する事象として、冷蔵庫の扉という使用者の食欲に密接な関係にあるものを選択したことによって、生活パターンの中でも比較的傾向のばらつきや外乱に因る悪影響が少ない要素で、基準パターンとの比較で居住者の体調の良否を比較的性格に判断することができる。しかも、電源の調達など別途操作内容を取得する為の設備が不要であるので、システムの運用コストや設備コストを安価に抑えることが可能となる。
【0025】
前記パターン保存手段によって保存された扉開閉実績パターンの統計を一定期間毎にとり、当該統計結果に基づいて前記扉開閉基準パターンを更新する基準更新手段を設けたことによって、ばらつきが少ない扉開閉基準パターンに対して、更に状況の変化に対する補正が加わりより正確な使用者の生活モニターが可能となる。

[0003]
[Patent Document 1]
Japanese Patent No. 2862320 [Patent Document 2]
Japanese Patent No. 2578972 [0004]
[Problems to be solved by the invention]
However, the opening and closing of doors such as toilets and entrances is an element that has a relatively large tendency in the life pattern, and lacks accuracy to judge the physical condition of the resident by comparing with the reference pattern. There is a face. Moreover, although the operation content of a lighting fixture etc. is an element with comparatively few dispersion | variation, in order to acquire the said operation content, the equipment for acquiring operation content separately, such as procurement of a power supply, is required. Even if the use of illumination is detected by using an optical sensor, there is a drawback that it is easily affected by disturbance such as light from the outside. Also, if more sensors are installed to ensure accuracy of judgment, this time, the equipment and processing contents for operating them will increase and a cost problem will arise.
[0005]
The present invention has been made in view of the above circumstances, and statistically has a relatively small variation in patterns, does not require any additional equipment work, and is less susceptible to disturbance. The purpose is to provide a transmission terminal device for door opening / closing detection and a life monitoring system.

A transmission circuit that receives a signal from the detection unit and transmits ID data of the transmission terminal device as a radio signal, and the detection unit includes a fine vibration detection sensor and an impact vibration detection sensor, and the fine vibration detection sensor A piezo element is used.
[0007]
The fine vibration detection sensor and the impact vibration detection sensor may be used as a single sensor or may be a separate sensor. Although a piezo element is used as the fine vibration detection sensor, it goes without saying that a piezo element can also be used for the impact vibration detection sensor.
[0008]

[0011]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of a life monitoring system using a refrigerator according to the present invention will be described below with reference to the drawings.
In this example, a refrigerator-attached transmission terminal device (hereinafter referred to as a transmission terminal device 12) that wirelessly transmits operational data indicating a change in status of a sensor that senses opening / closing of a door in the refrigerator 10, and the operational data is received. Based on the operation data, the number of operations of the sensor for a certain period and the operation time thereof are stored as a door opening / closing performance pattern of the refrigerator 10, respectively, and the door opening / closing performance pattern and the door opening / closing reference stored in advance. Pattern determining means 15 for comparing the pattern and estimating the physical condition of the resident, and comprising a relay terminal device 16 for transmitting to a predetermined destination when the estimation result is a determination that the physical condition is abnormal System (see FIG. 1).
[0012]
The transmission terminal device 12 includes a power supply unit 1, a transmission unit 2, and a detection unit 3.
The power supply unit 1 stores and discharges a secondary battery 5 such as a rectifier circuit 4 that converts alternating current electromotive force from a power supply source into direct current, and a direct current electromotive force that can be charged and discharged. The transmission unit 2 includes an amplifier circuit 13 that amplifies a pulse signal from a signal supply source to the level of a trigger signal for transmission, and the transmission terminal device 12 that receives the trigger signal and receives the trigger signal. The transmission unit 7 is configured to transmit operation data including the ID data as FM radio signals, and the detection unit 3 includes vibration detection sensors 8 and 9 (see FIGS. 2 and 3).
[0013]
The sensors 8 and 9 in this example employ the characteristics of piezoelectric elements that convert stress applied to the elements by vibration into electrical energy. Piezoceramics are used for the piezo elements. The piezo elements used as the sensors 8 and 9 generate an electromotive force by deformation caused by sine wave-like fine vibration constantly generated during operation of the refrigerator or relatively large shock vibration accompanying opening and closing of the door. Piezoceramics are generally in the form of discs or rods, but rods are said to be particularly excellent in response to relatively fine stress, and the vibrations that the refrigerator constantly generates are converted into electric power. It is suitable for effective use.
[0014]
The electromotive force of the piezo element is such that a pair of terminals provided on the piezo element are connected to the rectifier circuit 4 in such a manner that the output is full-wave rectified (half-wave rectification is also possible) as shown in FIG. Therefore, it functions as the power supply source of the transmission terminal device including the sensors 8 and 9 and also functions as a power source for wireless transmission. For example, as shown in FIG. 5, when the FET or the like is driven by the output directly drawn from both terminals of the piezo element and a pulse signal generated by a relatively large impact vibration than the fine vibration in the steady state is taken out, the door is opened and closed. Functions as a pulse signal source for operation data.
[0015]
The sensors 8 and 9 are housed in a casing together with other components of the transmission terminal device 12, and are mounted on the main body (or door) of the refrigerator 10 as shown in FIG. It is fixed by a fixing means such as an attached magnet, and detects the fine vibration and a relatively large shock vibration. The sensors 8 and 9 for detecting these may be provided individually as different sensors, or may be shared by one sensor. In addition, the sensors 8 and 9 may be housed and integrated with other components of the transmission terminal device 12, or other components of the transmission terminal device 12 may be accommodated. It may be pulled out from the case that has been made through a cable or the like. In that case, a fixing means such as a magnet is separately provided on the back surface of the sensor.
[0016]
On the other hand, the relay terminal device 16 includes wireless communication means 18 that receives operation data from the transmission terminal device 12, and the number of operations per fixed period of the shock vibration detection sensor 9 among the sensors based on the operation data. A pattern storage unit 14 that stores the operation time as a door opening / closing performance pattern of the refrigerator 10 and a pattern determination unit 15 that compares the door opening / closing performance pattern with a previously held door opening / closing reference pattern to estimate the physical condition of the resident. And statistics of the door opening / closing performance pattern stored by the pattern storage means 14 are taken at regular intervals, the reference updating means 17 for updating the door opening / closing reference pattern based on the statistical results, and the estimation result is an abnormal physical condition. And a notification means 19 for making a call to a predetermined destination when the determination is made (see FIG. 1B).
[0017]
The wireless communication unit 18, the pattern storage unit 14, the pattern determination unit 15, the reference update unit 17, and the notification unit 19 are controlled by control commands issued from the CPU circuit of the transmission terminal device 12 based on a control program. The operation data is monitored by the CPU circuit via the communication interface 21 and the communication control unit 20 of the wireless communication unit 18. For example, when operation data is received from the transmission terminal device 12, the operation data is The CPU circuit recognizes this with the reception flag set by the communication means 18 and prompts the pattern storage means 14 to save the operation data in a memory or the like.
[0018]
In this example, since the transmission data is transmitted from the transmission terminal device 12 as operation data indicating the timing of opening and closing of the door 11 of the refrigerator 10, the pattern storage unit 14 inverts the logic every time the operation data is received. At the same time, the time when the logic is inverted from the clock is stored in the memory. In this way, an opening / closing pattern of the door 11 of the refrigerator 10 having a common time axis is formed on the memory. As a method for detecting whether the door 11 is opened or closed, a limit switch 22 or the like that can output the open / closed state of the door 11 as a different status, for example, as shown in FIG.
[0019]
The opening / closing pattern of the door is the time when the door is opened / closed as described above on the time axis divided for each unit time zone by a function of the pattern storage means 14 for every short period such as one day. Is stored in the memory as a time-series pattern with either high / low status. The pattern determination means 15 forms determination data indicating the suitability of the door opening / closing pattern collected by comparing the opening / closing pattern of the door with a door opening / closing reference pattern of the same time period previously stored in a memory or the like. .
[0020]
The door opening / closing reference pattern includes, for example, statistics of a time period during which the door is opened and closed every medium and long period of time, such as one week, by the reference update unit 17. A time-series door opening / closing reference pattern is formed such that the door is opened and closed in a time zone where the frequency of opening and closing is higher than a certain threshold on the time axis divided for each zone. As a method of comparing the door opening / closing reference pattern and the daily door opening / closing pattern, if the door opening period in the daily door opening / closing pattern is included in the door opening period in the door opening / closing reference pattern, One way is to make it appropriate. Moreover, a certain prohibition requirement may be defined and conditions may be added to the determination criteria.
[0021]
When the pattern determining means 15 determines that the door opening / closing pattern of the day is inappropriate, a control command for starting notification processing is sent from the CPU circuit to the notification means 19. As the notification means 19, for example, packetized ID data given to the user of the system and the door opening / closing pattern pattern data determined to be inappropriate by receiving the control command by the notification control unit 23, The packet data may be transmitted via a communication line such as a telephone line to a predetermined reporting destination such as a separate family member, relative's house, or mobile phone 25 via the notification interface 24 (see FIG. 1 (A)). .
