Description

本発明は、インターホンに関し、特に住宅外部の通話装置と通話可能なものに関する。   The present invention relates to an interphone, and more particularly, to an intercom that can communicate with a telephone device outside a house.

インターホンは、例えば住宅内部に設置された親機と、住宅の外部、例えば玄関に設置された子機との間で、通話を行うものである。ところで、インターホンを設置した住宅の住人が外出しているときに、来客があった場合に、外出先から来客と通話可能としたインターホンが、例えば特許文献１に開示されている。   The interphone is used to make a call between a parent device installed inside a house and a child device installed outside the house, for example, at a front door. By the way, for example, Patent Document 1 discloses an interphone that can make a call with a visitor from the outside when a resident of the house where the interphone is installed is out.

この特許文献１の技術では、在宅の時には、在宅留守切換スイッチを在宅に切り換えて、玄関子機から呼び出しがあると、親機と玄関子機とで通話可能とし、留守の時には、在宅留守切換スイッチを留守に切り換えて、玄関子機から呼び出しがあると、親機は、予め定めた携帯電話に電話を掛け、親機を介して携帯電話と玄関子機との間で通話可能とする。   In the technology of Patent Document 1, when the user is at home, the home answering switch is switched to home, and if there is a call from the front cordless handset, the master unit and the front cordless handset can make a call. When the switch is set to absence and there is a call from the entrance cordless handset, the base phone calls a predetermined mobile phone so that the mobile phone and the entrance cordless handset can talk over the base phone.

特開平９−１６３０００号公報Japanese Patent Laid-Open No. 9-163000

特許文献１の技術によれば、玄関子機から呼出があると、携帯電話機に電話を掛けるが、携帯電話機が何らかの理由で応答しなかった場合の対処についてはなんら開示されていない。   According to the technique of Patent Document 1, when a call is made from the front door unit, a call is made to the mobile phone, but no countermeasure is disclosed when the mobile phone does not respond for some reason.

本発明は、外部の通話装置が応答しない場合でも、外部通話装置に連絡できる確率を高めたインターホンを提供することを目的とする。   An object of the present invention is to provide an interphone with an increased probability of being able to contact an external call device even when the external call device does not respond.

本発明の一態様によるインターホンは、親機と子機とを備えている。親機は、住宅の内部に設置され、住宅外部の複数の外部通話装置と通話可能である。外部通話装置としては、携帯電話機や、予め定めた固定電話機等がある。外部通話装置への通話は、公衆回線、例えば電話回線を使用することもできるし、インターネット等を使用することもできる。子機は、前記親機と通話可能である。この通話は無線で行うこともできるし、有線で行うこともできる。前記親機は、前記子機から呼び出しがあると、前記複数の外部通話装置のうち応答したものを除いて繰り返し前記各外部通話装置を呼び出す。   An interphone according to one embodiment of the present invention includes a parent device and a child device. The master unit is installed inside the house and can talk to a plurality of external call devices outside the house. Examples of the external call device include a mobile phone and a predetermined fixed phone. Calls to the external call device can use a public line such as a telephone line, or can use the Internet or the like. The slave unit can communicate with the master unit. This call can be performed wirelessly or wired. When there is a call from the slave unit, the base unit repeatedly calls the external call units except for ones that have responded among the plurality of external call units.

このように構成されたインターホンでは、子機からの呼出があると、親機は、複数の外部通話装置を、例えば予め定めた順に従って呼び出す。この呼出に応じるものがあると、それと通話を行う。複数の外部通話装置への呼出が一巡したときに、まだ呼出に応答していない外部通話装置があると、それらを対象として再び呼び出す。それによっても応答しないものがあると、呼出が一巡した後、さらに応答していないものを対象として呼び出す。これを繰り返すことによって、各外部通話装置とそれぞれ通話することができる確率が高くなる。   In the intercom configured as described above, when there is a call from the slave unit, the master unit calls a plurality of external call devices in accordance with, for example, a predetermined order. If there is something to answer this call, it will talk to it. When a call to a plurality of external call devices is completed, if there are external call devices that have not yet responded to the call, they are called again. If there is something that does not respond to the call, the call is made for a non-response after the call is completed. By repeating this, the probability that a call can be made with each external call device increases.

前記子機としては、が前記住宅の内部に設置されている緊急用子機を使用することができる。緊急用子機は、例えば無線を利用したもので、その設置場所に自由度がある。緊急用子機は、病人等の要介護者の傍に設置される。従って、要介護者が緊急の用事がある場合で、住宅内に介護者等が以内場合には、複数の外部通話装置に順に電話を掛け、全ての外部通話装置と通話できるように、応答していないものを除いて呼出を行うので、緊急の用事があることを確実に介護者等に連絡することができる。   As the handset, an emergency handset installed inside the house can be used. The emergency cordless handset uses radio, for example, and has a degree of freedom in its installation location. The emergency cordless handset is installed near the care recipient such as a sick person. Therefore, if the care recipient has an urgent business and there are no caregivers in the house, make a call to multiple external call devices in order and answer so that they can talk to all external call devices. Since calls are made except for those that are not, it is possible to reliably notify caregivers that there is an urgent business.

前記子機が前記住宅の外部に設置され、来訪者を検知する来訪者検知用子機とすることができる。来訪者検知用子機は、例えば住宅のドアや窓が開閉されたことや、住宅の所定の領域に来訪者があることを検知するセンサを備えている。   The said subunit | mobile_unit can be set as the subunit | mobile_unit for visitor detection which is installed in the exterior of the said house and detects a visitor. A visitor detection cordless handset is provided with the sensor which detects that the door and window of a house were opened and closed, for example, and that there is a visitor in the predetermined field of a house.

このように構成すると、来訪者、例えば不法侵入者があることを来訪者検知用子機のセンサが検知したとき、複数の外部通話装置を呼び出して通知するが、複数の通話装置を全て呼び出しても、応答しないものがあると、応答していないものを対象として再び呼び出す。このような呼出を繰り返すので、不法侵入者があることを確実に各外部通話装置に報知することができる確率が高くなる。   With this configuration, when the sensor of the visitor detection slave unit detects that there is a visitor, for example, a trespasser, a plurality of external call devices are called and notified. However, if there is something that does not respond, it calls again for those that do not respond. Since such a call is repeated, the probability that it is possible to reliably notify each external communication device that there is an illegal intruder increases.

以上のように、このインターホンによれば、複数の外部通話装置のうち、子機からの呼出に応答しない外部通話装置があっても、応答しない外部通話装置を対象として応答するまで繰り返し呼出を行うので、各外部通話装置に確実に子機から通知することができる確率を高めることができる。   As described above, according to this interphone, even if there is an external call device that does not respond to a call from a slave unit among a plurality of external call devices, the call is repeated until the external call device that does not answer is answered. Therefore, it is possible to increase the probability that each external communication device can be surely notified from the slave unit.

本発明の一実施形態のインターホンは、図１に示すように、親機４と複数の子機とを備えている。親機４は、住宅２内に設置されている。また、住宅の外部、例えば玄関には、各子機のうち外部子機、例えば玄関子機６が設置されている。さらに、住宅の外部、例えば不法侵入者が侵入しやすい場所には、各子機のうち来訪者検知用子機、例えばセンサ子機８が設置されている。センサ子機８は、異なる場所ごとにそれぞれ設置することもできる。また、住宅２内の異なる場所には、各子機のうち室内子機１０がそれぞれ設置されている。この実施の形態では、３台の室内子機１０が設置されている。なお、室内子機１０は設置されない場合もある。また、設置する場合でも、その台数は任意に変更することができる。さらに、住宅２内の要介護者がいる場所には、緊急用子機、例えばパニック釦１２が配置されている。パニック釦１２は、任意の場所に設置することができる。親機４は、玄関子機６、センサ子機８、室内子機１０、パニック釦１２とは無線によって通信回線を構成することができる。この無線による通信回線は、少ないチャンネルを使用したもので、例えば室内子機１０同士が通話を行っているような場合、他の子機からの呼出が親機４に伝わらないことがある。更に、親機４は、外部の公衆回線、例えば電話回線１４を介して外部通話装置、例えば携帯電話機１６ａ、１６ｂ、１６ｃと通話可能に構成されている。なお、外部通話装置としては携帯電話機の他に、固定電話機を使用することもできるし、電話回線以外にインターネットを公衆回線として使用することもできる。外部通話装置の台数も任意の台数とすることができる。   An interphone according to an embodiment of the present invention includes a parent device 4 and a plurality of child devices as shown in FIG. The base unit 4 is installed in the house 2. In addition, an external slave unit, for example, the entrance slave unit 6 among the slave units is installed outside the house, for example, the entrance. Furthermore, a visitor detection slave unit, for example, a sensor slave unit 8 among the slave units is installed outside the house, for example, in a place where an illegal intruder easily enters. The sensor slave unit 8 can also be installed at each different location. Moreover, the indoor subunit | mobile_unit 10 is each installed in the different place in the house 2 among each subunit | mobile_unit. In this embodiment, three indoor cordless handsets 10 are installed. The indoor cordless handset 10 may not be installed. Moreover, even when installing, the number can be changed arbitrarily. Further, an emergency handset, for example, a panic button 12 is disposed in the house 2 where a care recipient is present. The panic button 12 can be installed at an arbitrary place. The master unit 4 can form a communication line wirelessly with the entrance slave unit 6, the sensor slave unit 8, the indoor slave unit 10, and the panic button 12. This wireless communication line uses a small number of channels. For example, when the indoor slave units 10 are making a call, calls from other slave units may not be transmitted to the master unit 4. Furthermore, the base unit 4 is configured to be able to make a call with an external call device such as mobile phones 16a, 16b and 16c via an external public line such as a telephone line. In addition to the mobile phone, a fixed telephone can be used as the external call device, and the Internet can be used as a public line in addition to the telephone line. The number of external communication devices can also be any number.

このインターホンでは、図２に示すように、パニック釦１２の緊急釦１２ａが操作されると（ステップＳ２）、パニック釦１２は、親機４に呼出信号を送信する（ステップＳ４）。親機４から応答があるかパニック釦１２は判断し（ステップＳ６）、この判断の答えがイエスであると、親機４との通話動作に入る（ステップＳ８）。   In this intercom, as shown in FIG. 2, when the emergency button 12a of the panic button 12 is operated (step S2), the panic button 12 transmits a calling signal to the base unit 4 (step S4). The panic button 12 determines whether or not there is a response from the parent device 4 (step S6). If the answer to this determination is yes, a call operation with the parent device 4 is started (step S8).

ステップＳ６の判断の答えがノーの場合、パニック釦１２は、予め定めた第１の時間、例えば１分の経過を待ち（ステップＳ１０）、その後に親機４へ呼出信号を送信する（ステップＳ１２）。親機４から応答があるかパニック釦１２は判定し（ステップＳ１４）、応答があれば、ステップＳ８を実行して、親機４との通話動作に入る。   If the answer to the determination in step S6 is no, the panic button 12 waits for a predetermined first time, for example, 1 minute (step S10), and then transmits a call signal to the parent device 4 (step S12). ). The panic button 12 determines whether or not there is a response from the parent device 4 (step S14), and if there is a response, executes step S8 and starts a call operation with the parent device 4.

この判断の答えがノーの場合、パニック釦１２は、予め定めた第２の時間、例えば３０秒の経過を待ち（ステップＳ１６）、その後に親機４へ呼出信号を送信する（ステップＳ１８）。親機４から応答があるかパニック釦１２は判定し（ステップＳ２０）、応答があると、ステップＳ８を実行して、親機４との通話動作に入る。この判断の答えがノーの場合には、待機状態に入る（ステップＳ２２）。このようにパニック釦１２の緊急釦が１２ａが操作されると、親機４が応答するまで、複数回の呼出が時間をおいて行われる。   If the answer to this determination is no, the panic button 12 waits for a predetermined second time, for example, 30 seconds (step S16), and then transmits a call signal to the parent device 4 (step S18). The panic button 12 determines whether or not there is a response from the parent device 4 (step S20), and if there is a response, executes step S8 and starts a call operation with the parent device 4. If the answer to this determination is no, a standby state is entered (step S22). In this way, when the emergency button 12a of the panic button 12 is operated, a plurality of calls are made at intervals until the master unit 4 responds.

なお、室内子機１０の通報／停止釦１０ｄが操作された場合にも、室内子機１０は、図２のフローチャートで示すように動作をする。   Even when the notification / stop button 10d of the indoor child device 10 is operated, the indoor child device 10 operates as shown in the flowchart of FIG.

また、センサ子機８が侵入者等を検知すると、図３に示すように、親機４に呼出信号を送信する（ステップＳ２４）。親機４から応答があるかセンサ子機８は判断し（ステップＳ２６）、この判断の答えがイエスであると、センサ子機８は停止する（ステップＳ２８）。   Further, when the sensor slave unit 8 detects an intruder or the like, a call signal is transmitted to the master unit 4 as shown in FIG. 3 (step S24). The sensor slave unit 8 determines whether there is a response from the master unit 4 (step S26). If the answer to this determination is yes, the sensor slave unit 8 stops (step S28).

ステップＳ２６の判断の答えがノーの場合、センサ子機８は、予め定めた第１の時間、例えば１分の経過を待ち（ステップＳ３０）、その後に親機４へ呼出信号を送信する（ステップＳ３２）。親機４から応答があるかセンサ子機８は判定し（ステップＳ３４）、応答があれば、ステップＳ２８を実行する。   If the answer to the determination in step S26 is no, the sensor slave unit 8 waits for a predetermined first time, for example, one minute (step S30), and then transmits a call signal to the master unit 4 (step S30). S32). The sensor slave unit 8 determines whether or not there is a response from the master unit 4 (step S34), and if there is a response, executes step S28.

この判断の答えがノーの場合、センサ子機８は、予め定めた第２の時間、例えば３０秒の経過を待ち（ステップＳ３６）、その後に親機４へ呼出信号を送信する（ステップＳ３８）。親機４から応答があるかセンサ子機８は判定し（ステップＳ４０）、応答があると、ステップＳ２８を実行する。この判断の答えがノーの場合には、待機状態に入る（ステップＳ４２）。このようにセンサ子機８が侵入者を検知すると、親機４が応答するまで、複数回の呼出が時間をおいて行われる。   If the answer to this determination is no, the sensor slave unit 8 waits for a predetermined second time, for example, 30 seconds (step S36), and then transmits a call signal to the master unit 4 (step S38). . The sensor slave unit 8 determines whether or not there is a response from the master unit 4 (step S40), and if there is a response, executes step S28. If the answer to this determination is no, a standby state is entered (step S42). When the sensor slave unit 8 detects an intruder in this way, a plurality of calls are made at intervals until the master unit 4 responds.

また、玄関子機６が呼出を行うと、玄関子機６は図４にフローチャートで示す処理を行う。玄関子機６の呼出釦６ａが操作されると（ステップＳ４４）、玄関子機６は、親機４に呼出信号を送信する（ステップＳ４６）。親機４から応答があるか玄関子機６が判断し（ステップＳ４８）、この判断の答えがイエスの場合、親機との通話動作を行う（ステップＳ５０）。ステップＳ４８の判断の答えがノーの場合、一定時間経過したか判断し（ステップＳ５２）、その判断の答えがノーの場合、再びステップＳ４８を実行する。またステップＳ５２の判断の答えがイエスの場合、玄関子機６は待機状態となる（ステップＳ５４）。このように玄関子機６は、呼出釦６ａを操作した後、一定時間の間に親機４から応答があると、親機４と通話が行えるが、一定時間の間に親機４からの応答が無い場合には待機状態となる。   Further, when the front door 6 makes a call, the front door 6 performs the processing shown in the flowchart of FIG. When the call button 6a of the front door device 6 is operated (step S44), the front door device 6 transmits a call signal to the parent device 4 (step S46). The front handset 6 determines whether there is a response from the base unit 4 (step S48). If the answer to this determination is yes, a call operation with the base unit is performed (step S50). If the answer to the determination in step S48 is no, it is determined whether a predetermined time has passed (step S52). If the answer to the determination is no, step S48 is executed again. If the answer to the determination at step S52 is yes, the front cordless handset 6 enters a standby state (step S54). As described above, if the front cordless handset 6 operates the call button 6a and receives a response from the base unit 4 for a certain time, the front handset 4 can make a call with the base unit 4. When there is no response, it enters a standby state.

また、室内子機１０がいずれかの子機釦１０ｃまたは呼出／応答釦１０ｅを操作して、他の子機または親機４の呼出を行うと、室内子機１０は、図５にフローチャートで示すような処理を行う。室内子機１０において、子機釦１０ｃまたは呼出／応答釦１０ｅが操作される（ステップＳ５６）と、室内子機１０は親機４に呼出信号を送信する（ステップＳ５８）。そして、親機４から応答があったか判断する（ステップＳ６０）。この判断の答えがイエスの場合、親機４とまたは親機４を介して他の室内子機１０と通話動作を行う（ステップＳ６２）。   Further, when the indoor child device 10 calls one of the child device buttons 10c or the call / response button 10e to call another child device or the parent device 4, the indoor child device 10 is shown in a flowchart in FIG. Perform proper processing. In the indoor child device 10, when the child device button 10c or the call / response button 10e is operated (step S56), the indoor child device 10 transmits a calling signal to the parent device 4 (step S58). And it is judged whether there was a response from the main | base station 4 (step S60). If the answer to this determination is yes, a call operation is performed with the parent device 4 or with another indoor child device 10 via the parent device 4 (step S62).

ステップＳ６０における判断の答えがノーの場合、一定時間経過したか判断し（ステップＳ６８）、この判断の答えがノーの場合には、再びステップＳ６０を実行する。そしてステップＳ６８の判断の答えがイエスの場合には、待機状態となる（ステップＳ７０）。このように室内子機１０は、子機釦１０ｃまたは呼出／応答釦１０ｅを操作した後、一定時間の間に親機４から応答があると、親機４または親機４を介して他の室内子機１０と通話が行えるが、一定時間の間に親機４からの応答が無い場合には待機状態となる。   If the answer to the determination in step S60 is no, it is determined whether a predetermined time has passed (step S68). If the answer to this determination is no, step S60 is executed again. If the answer to the determination at step S68 is yes, a standby state is entered (step S70). As described above, if the indoor child device 10 responds from the parent device 4 for a predetermined time after operating the child device button 10c or the call / response button 10e, the indoor child device 10 receives another response via the parent device 4 or the parent device 4. A call can be made with the indoor slave unit 10, but when there is no response from the master unit 4 for a certain period of time, a standby state is entered.

上記のようにして、屋外子機６、センサ子機８、室内子機１０またはパニック釦１２からの呼出があると、親機４は、図６（ａ）または（ｂ）のフローチャートで示すように動作する。即ち、図６（ａ）に示すように、パニック釦１２の緊急釦１２ａまたは室内子機１０の通報／停止釦１０ｄが操作されたことにより緊急呼出信号を親機４が受信する（ステップＳ６８）と、パニック警報動作を行う（ステップＳ７０）。   As described above, when there is a call from the outdoor slave unit 6, the sensor slave unit 8, the indoor slave unit 10, or the panic button 12, the master unit 4 is as shown in the flowchart of FIG. 6 (a) or (b). To work. That is, as shown in FIG. 6A, the base unit 4 receives the emergency call signal when the emergency button 12a of the panic button 12 or the notification / stop button 10d of the indoor unit 10 is operated (step S68). Then, a panic alarm operation is performed (step S70).

パニック警報動作では、図７に示すように、親機４は全室内子機１０にパニック信号を送信する（ステップＳ７２）。これによって、各室内子機１０は、警報ランプ１０ａを点滅動作させ、所定時間、例えば１分間の警報音を発生する。ステップＳ７２に続いて、親機４は、警報ランプ４ａを点滅動作させ、所定時間、例えば１分間の警報音を発生する（ステップＳ７４）。これら警報ランプ４ａ及び警報音発生装置が、呼出報知手段に相当する。そして、予め登録されている複数の登録先、例えば携帯電話機１６ａ、１６ｂ、１６ｃのうち１台に電話をかける（ステップＳ７６）。   In the panic alarm operation, as shown in FIG. 7, base unit 4 transmits a panic signal to all indoor unit 10 (step S72). Thus, each indoor unit 10 causes the alarm lamp 10a to blink, and generates an alarm sound for a predetermined time, for example, 1 minute. Subsequent to step S72, the base unit 4 causes the alarm lamp 4a to blink, and generates an alarm sound for a predetermined time, for example, 1 minute (step S74). The alarm lamp 4a and the alarm sound generator correspond to a call notification unit. Then, a call is made to one of a plurality of registration destinations registered in advance, for example, the mobile phones 16a, 16b, and 16c (step S76).

次に、親機４は判定を行う（ステップＳ７８）。即ち、電話を掛けた登録先から応答があったか、親機４の一斉呼出／応答釦４ｈが操作されて親機４が応答したか、或いは親機４からも携帯電話機からも応答が無いか判断する。一斉呼出／応答釦４ｈが呼出応答手段に相当する。   Next, the base unit 4 performs determination (step S78). That is, it is determined whether there is a response from the registration destination that made the call, whether the master device 4 responds by operating the general call / response button 4h of the master device 4, or whether there is no response from the master device 4 or the mobile phone. To do. The simultaneous call / response button 4h corresponds to a call response means.

登録先が応答したと判定されると、親機４はパニック釦１２または室内子機１０（通報／停止釦１０ｄが操作されたもの）に応答信号を送信し、他の室内子機１０に決定信号を送信する（ステップＳ８０）。この決定信号の送信によって各室内子機１０は、警報ランプ１０ａの点滅動作を中止する。そして、登録先の携帯電話機とパニック釦１２または通報／停止釦１０ｄが操作された室内子機１０との間に通話路を開設し、通話が開始される（ステップＳ８２）。そして、この通話が終了したか親機４は判定し（ステップＳ８４）、この判断の答えがノーの場合には通話が開始されてから所定時間、例えば３分が経過しているか判断する（ステップＳ８６）。この判断の答えがノーの場合には、ステップＳ８４を再び実行する。そして、ステップＳ８４またはＳ８６の判断の答えがイエスになると、即ち、通話が終了するか通話開始から一定時間が経過すると、次の登録先があるか判断し（ステップＳ８８）、その判断の答えがイエスの場合には、次の登録先に電話を掛け（ステップＳ９０）、ステップＳ７８を再び実行する。従って、次の登録先に電話を掛けて、応答があれば、ステップＳ８０、Ｓ８２、Ｓ８４、Ｓ８６が実行され、次の登録先と通話が行われる。   If it is determined that the registration destination has responded, base unit 4 transmits a response signal to panic button 12 or indoor unit 10 (the one in which report / stop button 10d has been operated), and determines to other indoor unit 10 A signal is transmitted (step S80). By transmitting this determination signal, each indoor unit 10 stops the blinking operation of the alarm lamp 10a. Then, a call path is established between the registered mobile phone and the indoor cordless handset 10 on which the panic button 12 or the report / stop button 10d is operated, and the call is started (step S82). Then, base unit 4 determines whether or not the call has ended (step S84). If the answer to this determination is no, it is determined whether a predetermined time, for example, 3 minutes has elapsed since the call was started (step S84). S86). If the answer to this determination is no, step S84 is executed again. Then, when the answer to the determination in step S84 or S86 is yes, that is, when the call is ended or when a certain time has elapsed from the start of the call, it is determined whether there is a next registration destination (step S88). If yes, the next registration destination is called (step S90) and step S78 is executed again. Therefore, if a call is made to the next registration destination and there is a response, steps S80, S82, S84, and S86 are executed, and a call is made with the next registration destination.

ステップＳ８８の判断の答えがノーの場合、全ての登録先に電話を掛けたことになる。そこで、全ての登録先のうち未応答のものがあるか判断し（ステップＳ９２）、この判断の答えがノーの場合、親機４は待機状態となり、パニック釦１２または通報／停止釦１０ｄが操作された室内子機１０はスリープ状態となる（ステップＳ９４）。   If the answer to the determination in step S88 is no, it means that all registration destinations have been called. Therefore, it is determined whether there is an unanswered one among all the registered destinations (step S92). If the answer to this determination is no, the base unit 4 enters a standby state and the panic button 12 or the report / stop button 10d is operated. The indoor child device 10 thus set enters the sleep state (step S94).

ステップＳ９２の判断の答えがイエスの場合、それら未応答の登録先全てに規定回数リダイヤルしたか判断し（ステップＳ９６）、その判断の答えがイエスの場合には、ステップＳ９４を実行し、その判断の答えがノーの場合には、ステップＳ９０が実行される。   If the answer to the determination in step S92 is yes, it is determined whether all the unanswered registration destinations have been redialed a specified number of times (step S96). If the answer to the determination is yes, step S94 is executed and the determination is made. If the answer is no, step S90 is executed.

従って、全ての登録先に電話が掛けられ、所定回数リダイヤルするまでに全ての登録先が応答すれば、待機状態及びスリープ状態に親機４及びパニック釦１２（または通報／停止釦１０ｄが操作された室内子機１０）はなるが、所定回数リダイヤルするまでに全ての登録先が応答するまで、登録先に電話が掛けられる。   Therefore, if all the registered destinations are called and all the registered destinations answer before the predetermined number of redials, the master unit 4 and the panic button 12 (or the report / stop button 10d are operated in the standby state and the sleep state). However, the registration destinations are called until all the registration destinations answer before the predetermined number of redials.

ステップＳ７８において、親機４が応答したと判断されると、親機４はパニック釦１２または通報／停止釦１０ｄが操作された室内子機１０に応答信号を送信し、室内子機に決定信号を送信する（ステップＳ９８）。この決定信号に応じて各室内子機１０は警報ランプ１０ａの点滅を中止する。そして、親機４とパニック釦１２または通報／停止釦１０ｄが操作された室内子機１０との間で通話路を開設し、通話が開始される（ステップＳ１００）。そして、再びステップＳ７８の判定が行われる。従って、親機４とパニック釦１２または通報／停止釦１０ｄが操作された室内子機１０との間で通話が行われていても、登録先が応答すると、ステップＳ７８からステップＳ８０以降が実行され、登録先との通話が優先される。   If it is determined in step S78 that the base unit 4 has responded, the base unit 4 transmits a response signal to the indoor unit 10 in which the panic button 12 or the notification / stop button 10d is operated, and a determination signal is transmitted to the indoor unit. Is transmitted (step S98). In response to this determination signal, each indoor unit 10 stops blinking of the alarm lamp 10a. Then, a communication path is established between the parent device 4 and the indoor child device 10 in which the panic button 12 or the report / stop button 10d is operated, and the call is started (step S100). And determination of step S78 is performed again. Therefore, even if a call is made between the base unit 4 and the indoor unit 10 in which the panic button 12 or the notification / stop button 10d is operated, if the registration destination responds, steps S78 to S80 and subsequent steps are executed. Priority is given to calls with registered parties.

ステップＳ７８において、登録先も親機も応答しないと判定されると、登録先に所定回数コールしたか判断し（ステップＳ１０２）、その判断の答えがノーの場合には、ステップＳ７８が再び実行され、ステップＳ１０２の判断の答えがイエスの場合、ステップＳ８８以降が実行される。   If it is determined in step S78 that neither the registration destination nor the base unit responds, it is determined whether a call has been made to the registration destination a predetermined number of times (step S102). If the answer to the determination is no, step S78 is executed again. If the answer to the determination at step S102 is yes, step S88 and subsequent steps are executed.

上記のように親機４とパニック釦１２等との間で通話が行われていても、全ての登録先が応答するまで親機４は登録先の呼出を行うので、登録先に確実に緊急事態の発生を報知することができる。例えば図８に示すように登録先として携帯電話機１６ａ、１６ｂ、１６ｃが登録されており、リダイヤル回数が５回と設定されているとする。１回目に親機４は携帯電話機１６ａを呼び出すが、応答がなければ、携帯電話機１６ｂを呼び出す。これも応答が無ければ携帯電話機１６ｃを呼び出す。これで１回目の呼出は終了したが、いずれも応答が無いので、２回目の呼出を行う。２回目の呼出において携帯電話機１６ｂが応答したとすると、３回目の呼出では携帯電話機１６ａ、１６ｃの順に呼び出し、携帯電話機１６ｂの呼び出しは行わない。３回目で携帯電話機１６ａ、１６ｃの応答が無ければ、４回目の呼び出しを携帯電話機１６ａ、１６ｃに行う。ここで、携帯電話機１６ａが応答したとすると、最後の５回目の呼び出しは未応答の携帯電話機１６ｃに対してのみ行う。ここで、携帯電話機１６ｃからの応答がなければ、呼び出しを中止する。   Even if a call is made between the parent device 4 and the panic button 12 or the like as described above, the parent device 4 calls the registration destination until all the registration destinations answer. The occurrence of the situation can be notified. For example, as shown in FIG. 8, it is assumed that mobile phones 16a, 16b, and 16c are registered as registration destinations, and the number of redials is set to five. The first time base phone 4 calls mobile phone 16a, but if there is no response, it calls mobile phone 16b. If there is no response, the mobile phone 16c is called. This completes the first call, but since no response is received, the second call is performed. If the mobile phone 16b answers in the second call, the mobile phone 16b is called in the order of the mobile phones 16a and 16c in the third call, and the mobile phone 16b is not called. If there is no response from the mobile phones 16a and 16c at the third time, the fourth call is made to the mobile phones 16a and 16c. Here, if the mobile phone 16a responds, the final fifth call is made only to the unanswered mobile phone 16c. Here, if there is no response from the mobile phone 16c, the calling is stopped.

図６（ｂ）に戻って親機４がセンサ子機８、玄関子機６または室内子機１０からの呼出信号を受信したとき（ステップＳ１０４）、呼出信号がセンサ子機８からのものか判断する（ステップＳ１０６）、その判断の答えがイエスの場合、センサ警報動作を行う（ステップＳ１０８）。ステップＳ１０６の判断の答えがノーの場合、玄関子機６からの呼出か判断し（ステップＳ１１０）、その判断の答えがイエスの場合には、玄関子機呼出動作を行い（ステップＳ１１２）、その判断の答えがノーの場合には、室内子機呼出動作を行う（ステップＳ１１４）。   Returning to FIG. 6B, when the master unit 4 receives a call signal from the sensor slave unit 8, the entrance slave unit 6 or the indoor slave unit 10 (step S104), is the call signal from the sensor slave unit 8? Judgment is made (step S106). If the answer to the decision is yes, a sensor alarm operation is performed (step S108). If the answer to the determination in step S106 is no, it is determined whether the call is from the front door 6 (step S110). If the answer is yes, a call to the front door is performed (step S112). If the answer to the determination is no, an indoor cordless handset calling operation is performed (step S114).

図９に示すようにセンサ警報動作では、親機４が在宅モードであるか判断する（ステップＳ１１６）。例えば、親機４の在宅釦４ｆが操作され、転送／外出釦４ｅが操作されていないか判断する。この判断の答えがイエスの場合、在宅モードセンサ警報オン動作が行われ（ステップＳ１１８）、この判断の答えがノーの場合には、在宅釦４ｆが操作されずに、転送／外出釦４ｅが操作されて、外出モードであるので、外出モードセンサ警報オン動作が行われる（ステップＳ１２０）。   As shown in FIG. 9, in the sensor alarm operation, it is determined whether the parent device 4 is in the home mode (step S116). For example, it is determined whether the home button 4f of the parent device 4 is operated and the transfer / outing button 4e is not operated. If the answer to this determination is yes, a home mode sensor alarm on operation is performed (step S118). If the answer to this determination is no, the home button 4f is not operated and the transfer / outing button 4e is operated. Since it is the outing mode, the outing mode sensor alarm ON operation is performed (step S120).

在宅モードセンサ警報オン動作では、親機４は全室内子機１０へセンサ警報信号を送信し、各室内子機１０は、警報ランプ１０ａを点滅動作させ、警報音を所定時間、例えば一分間発生させる。同時に親機４はそれの警報ランプ４ａを点滅させ、警報音を所定時間例えば一分間発生させる。   In the home mode sensor alarm ON operation, the master unit 4 transmits a sensor alarm signal to all the indoor slave units 10, and each indoor slave unit 10 causes the alarm lamp 10a to blink and generates an alarm sound for a predetermined time, for example, one minute. Let At the same time, the base unit 4 blinks its alarm lamp 4a and generates an alarm sound for a predetermined time, for example, one minute.

外出モードセンサ警報オン動作では、図１０に示すように、親機４は全室内子機１０へセンサ警報信号を送信する（ステップＳ１２２）。これによって、各室内子機１０はセンサ警報動作を行う（ステップＳ１２４）。このセンサ警報動作では、各室内子機１０は、警報ランプ１０ａを点滅動作させ、警報音を所定時間、例えば一分間動作させる。ステップＳ１２２に続いて、親機４は、警報ランプ４ａを点滅動作させ、所定時間、例えば一分間警報を発生する（ステップＳ１２６）。   In the going-out mode sensor alarm ON operation, as shown in FIG. 10, base unit 4 transmits a sensor alarm signal to all indoor units 10 (step S122). Thereby, each indoor unit 10 performs a sensor alarm operation (step S124). In this sensor alarm operation, each indoor slave unit 10 causes the alarm lamp 10a to blink, and operates the alarm sound for a predetermined time, for example, for one minute. Subsequent to step S122, base unit 4 causes alarm lamp 4a to blink, and issues an alarm for a predetermined time, for example, one minute (step S126).

次に、登録先に電話を掛ける（ステップＳ１２８）。登録先から応答があるか判断し（ステップＳ１３０）、その判断の答えがイエスの場合には、親機４はセンサ子機８に応答信号を、室内子機に決定信号を送信し、かつ侵入者ありの音声情報を登録先に報知する（ステップＳ１３２）。侵入者ありの音声情報は親機４が備えるＲＯＭ（図示せず）に記憶されている音声データをアナログ化したものである。   Next, a telephone call is made to the registration destination (step S128). It is determined whether there is a response from the registration destination (step S130). If the determination result is yes, the base unit 4 transmits a response signal to the sensor slave unit 8, transmits a determination signal to the indoor unit, and enters. The voice information with the person is notified to the registration destination (step S132). The voice information with an intruder is analogized voice data stored in a ROM (not shown) provided in the master unit 4.

ステップＳ１３０の判断の答えがノーの場合には、規定回数登録先にコールしたか判断し（ステップＳ１４４）、その判断の答えがノーの場合には、ステップＳ１３０を再び実行する。ステップＳ１４４の判断の答えがイエスの場合、またはステップＳ１３２に続いて、即ち、登録先が応答しない場合、または登録先が応答して侵入者ありを登録先に通知した後に、次の登録先があるか判断する（ステップＳ１４６）。この判断の答えがイエスの場合には、次の登録先に電話を掛け（ステップＳ１４８）、その後にステップＳ１３０を実行する。従って、次の登録先でも電話を取ると、侵入者ありの音声情報が送信される。   If the answer to the determination in step S130 is no, it is determined whether or not the call has been made to the specified number of registration destinations (step S144). If the answer to the determination is no, step S130 is executed again. If the answer to the determination in step S144 is yes, or following step S132, that is, if the registration destination does not respond, or the registration destination responds and notifies the registration destination that there is an intruder, the next registration destination is It is determined whether or not there is (step S146). If the answer to this determination is yes, a call is made to the next registration destination (step S148), and then step S130 is executed. Therefore, when the next registration destination takes a call, the voice information with an intruder is transmitted.

ステップＳ１４６の判断の答えがノーの場合、即ち、全ての登録先に電話が終了すると、これら登録先に未応答のものがあるか判断する（ステップＳ１５０）。この判断の答えがノーの場合には、親機４を待機状態、センサ子機８はスリープ状態に戻る（ステップＳ１５２）。ステップＳ１５０の判断の答えがイエスの場合、まだ未応答の登録先があるので、未応答の登録先に規定回数リダイヤルしたか判断し（ステップＳ１５４）、その判断の答えがイエスの場合には、ステップＳ１５２を実行し、ステップＳ１５４の判断の答えがノーの場合、ステップＳ１４８を実行する。   If the answer to the determination in step S146 is no, that is, if the telephones are terminated for all the registered destinations, it is determined whether there are unanswered ones in these registered destinations (step S150). If the answer to this determination is no, the master unit 4 is returned to the standby state, and the sensor slave unit 8 is returned to the sleep state (step S152). If the answer to the determination in step S150 is yes, there is still an unanswered registration destination. Therefore, it is determined whether or not the unanswered registration destination has been redialed a prescribed number of times (step S154). If the answer to the determination is yes, Step S152 is executed, and if the answer to the determination in step S154 is no, step S148 is executed.

従って、図８に示したのと同様にして、各登録先が応答するまで、所定リダイヤル回数にわたって、各登録先に電話が掛けられる。但し、応答した登録先については電話が掛けられない。このようにして各登録先に確実に侵入者がある旨を報知できる。   Therefore, in the same manner as shown in FIG. 8, each registered address is called over the predetermined number of redials until each registered address responds. However, no telephone call can be made to the responding registration destination. In this way, it can be notified that there is an intruder at each registration destination.

玄関子機６からの呼出の際に親機４が実行する玄関子機呼出動作では、図１１に示すように親機が在宅モードであるか判断する（ステップＳ１５６）。この判断の答えがイエスの場合、在宅モードが実行され（ステップＳ１５８）、この判断の答えがノーの場合、外出モードが実行される（ステップＳ１６０）。   In the entrance slave device calling operation executed by the master device 4 when calling from the entrance slave device 6, it is determined whether the master device is in the home mode as shown in FIG. 11 (step S156). If the answer to this determination is yes, the home mode is executed (step S158), and if the answer to this determination is no, the outing mode is executed (step S160).

在宅モードでは、図１２に示すように、親機４は、全室内子機１０に玄関子機６から呼出信号を受信したことを表す信号を送信し、チャイム音を数回発生させる（ステップＳ１６２）。これに応動して、各室内子機１０では、室内子機１０の玄関子機呼出操作が行われ（ステップＳ１６４）、具体的にはチャイム音が鳴り、警報ランプ１０ａが点滅する。ステップＳ１６２に続いて、親機４の一斉呼出／応答釦４ｈが操作されたか判断する（ステップＳ１６６）。この判断の答えがイエスの場合には、親機４は玄関子機６へ応答信号を送信し、室内子機１０に決定信号を送信する（ステップＳ１６８）。これによって、各室内子機１０の警報ランプ１０ａは点滅動作を中止する。ステップＳ１６８に続いて、親機４と玄関子機６との間で通話が行われる（ステップＳ１７０）。   In the home mode, as shown in FIG. 12, the base unit 4 transmits a signal indicating that the calling signal has been received from the entrance handset 6 to all the indoor handsets 10, and generates a chime sound several times (step S162). ). In response to this, in each indoor unit 10, the door unit call operation of the indoor unit 10 is performed (step S 164), specifically, a chime sound is emitted and the alarm lamp 10 a flashes. Subsequent to step S162, it is determined whether the general call / response button 4h of the parent device 4 has been operated (step S166). If the answer to this determination is yes, the base unit 4 transmits a response signal to the front door unit 6 and transmits a determination signal to the indoor unit 10 (step S168). As a result, the alarm lamp 10a of each indoor unit 10 stops blinking. Subsequent to step S168, a call is performed between the parent device 4 and the front door device 6 (step S170).

ステップＳ１６６の判断の答えがノーの場合、親機４は、いずれかの室内子機１０からその呼出／応答釦１０ｅを操作した旨を表す信号を受信したか判断する（ステップＳ１７２）。この判断の答えがイエスの場合には、親機４は玄関子機６へ応答信号を送信する（ステップＳ１７４）。これに続いて、室内子機１０と玄関子機６との間に親機４を介して通話が行われる（ステップＳ１７６）。   If the answer to the determination in step S166 is no, the parent device 4 determines whether a signal indicating that the call / response button 10e has been operated is received from any indoor child device 10 (step S172). If the answer to this determination is yes, the base unit 4 transmits a response signal to the front door unit 6 (step S174). Following this, a call is made between the indoor unit 10 and the entrance unit 6 via the base unit 4 (step S176).

ステップＳ１７２の判断の答えがノーの場合、予め定めた規定呼出時間が経過しているか判断し（ステップＳ１７８）、この判断の答えがノーの場合にはステップＳ１６６から再び実行し、この判断の答えがイエスの場合には、親機４、室内子機１０は待機状態に、玄関子機６はスリープ状態に戻る（ステップＳ１８０）。   If the answer to the determination in step S172 is no, it is determined whether a predetermined specified call time has elapsed (step S178). If the answer to this determination is no, the process is executed again from step S166. Is YES, the master unit 4 and the indoor unit 10 return to the standby state, and the entrance unit 6 returns to the sleep state (step S180).

従って、在宅モードでは、規定呼出時間の間に、親機４または室内子機１０のうちいずれか先に応答したものが、玄関子機６と通話可能となり、規定呼出時間内に親機４も室内子機１０のいずれもが応答しないと、親機４、室内子機１０は待機状態に、玄関子機６はスリープ状態に戻る。   Accordingly, in the home mode, any one of the parent device 4 or the indoor child device 10 that has responded first during the specified calling time can make a call with the entrance child device 6, and the parent device 4 can also be within the specified calling time. If none of the indoor slave units 10 responds, the master unit 4 and the indoor slave unit 10 return to the standby state, and the entrance slave unit 6 returns to the sleep state.

図１３に示すように、外出モードでは、親機４は、チャイム音を数回発生し（ステップＳ１８２）、登録先に電話を掛ける（ステップＳ１８４）。登録先が電話を取ったか判断し（ステップＳ１８６）。その判断の答えがイエスの場合には、親機４は玄関子機６へ応答信号を送信し（ステップＳ１８８）、登録先と玄関子機６との間で通話が行われる（ステップＳ１９０）。   As shown in FIG. 13, in the outing mode, base unit 4 generates a chime sound several times (step S182) and makes a call to the registration destination (step S184). It is determined whether the registration destination has picked up the telephone (step S186). If the answer to the determination is yes, the base unit 4 transmits a response signal to the front door 6 (step S188), and a call is made between the registration destination and the front door 6 (step S190).

ステップＳ１８６の判断の答えがノーの場合、規定回数登録先をコールしたか判断し（ステップＳ１９２）。その判断の答えがノーの場合には、ステップＳ１８６を実行する。この判断の答えがイエスの場合には、次の登録先があるか判断し（ステップＳ１９４）。その判断の答えがイエスの場合には、次の登録先に電話をかけ（ステップＳ１９６）、ステップＳ１８６を再び実行する。ステップＳ１９４の判断の答えがノーの場合、即ち全ての登録先に電話をかけた場合、未応答の登録先があるか判断する（ステップＳ１９８）。この判断の答えがノーの場合、親機４は待機状態となり、玄関子機６はスリープ状態となる（ステップＳ２００）。ステップＳ１９８の判断の答えがイエスの場合には、未応答の登録先に規定回数リダイヤルしたか判断し（ステップＳ２０２）、その判断の答えがイエスの場合にはステップＳ２００を実行し、その判断の答えがノーの場合には、ステップＳ１９６を実行する。   If the answer to the determination in step S186 is no, it is determined whether the specified number of registration destinations has been called (step S192). If the answer to the determination is no, step S186 is executed. If the answer to this determination is yes, it is determined whether there is a next registration destination (step S194). If the answer is yes, a call is made to the next registration destination (step S196), and step S186 is executed again. If the answer to the determination in step S194 is no, that is, if all the registration destinations are called, it is determined whether there is an unanswered registration destination (step S198). If the answer to this determination is no, the master unit 4 is in a standby state and the entrance slave unit 6 is in a sleep state (step S200). If the answer to the determination in step S198 is yes, it is determined whether or not the unanswered registration destination has been redialed a specified number of times (step S202). If the answer to the determination is yes, step S200 is executed. If the answer is no, step S196 is executed.

従って、外出モードでは、玄関子機６から呼出があると、全ての登録先が応答するまで、応答したものを除いて繰り返し呼出が行われる。但し、規定回数リダイヤルしても、応答しない場合には、親機４は待機状態に、玄関子機６はスリープ状態になる。   Therefore, in the outing mode, when there is a call from the front cordless handset 6, the call is repeatedly made except for the ones that have responded until all registered destinations answer. However, if no response is made after redialing the specified number of times, the base unit 4 is in a standby state and the entrance unit 6 is in a sleep state.

図６に示す室内子機呼出動作（ステップＳ１１４）では、例えば図１４に示すように、親機４は、親機４の一斉／押釦４ｈが操作されたか判断し（ステップＳ２０４）、この判断の答えがイエスの場合には、親機４は呼び出した室内子機１０に応答信号を送信し（ステップＳ２０６）、その室内子機１０と親機４との間に通話路を形成し、通話を行う（ステップＳ２０８）。そして、通話終了の指示が親機４または室内子機１０からあったか判断し（ステップＳ２１０）、その判断の答えがノーの場合には、通話開始から所定時間、例えば１分が経過したか判断する（ステップＳ２１２）。この判断の答えがノーの場合には、ステップＳ２１０を再び実行する。ステップＳ２１０またはＳ２１２の判断の答えがイエスになったとき、通話路を閉じて、通話を終了させる（ステップＳ２１４）。   In the indoor cordless handset calling operation (step S114) shown in FIG. 6, for example, as shown in FIG. 14, the base unit 4 determines whether the simultaneous / push button 4h of the base unit 4 is operated (step S204). If the answer is yes, the base unit 4 transmits a response signal to the called indoor unit 10 (step S206), forms a communication path between the indoor unit 10 and the base unit 4, and makes a call. This is performed (step S208). Then, it is determined whether an instruction to terminate the call has been issued from the parent device 4 or the indoor child device 10 (step S210). (Step S212). If the answer to this determination is no, step S210 is executed again. When the answer to step S210 or S212 is YES, the call path is closed and the call is terminated (step S214).

ステップＳ２０４の判断の答えがノーの場合、即ち親機４の一斉／押釦４ｈが操作されていない場合には、他の室内子機１０の呼出／応答釦１０ｅが操作されているか判断し（ステップＳ２１６）、その判断の答えがイエスの場合には、親機４は呼び出した室内子機へ応答信号を送信し（ステップＳ２１８）、呼び出した室内子機１０と呼び出された室内子機１０との間に親機４を介して通話路を形成する（ステップＳ２２０）。そして、ステップＳ２１０以降を実行する。   If the answer to the determination in step S204 is no, that is, if the simultaneous / push button 4h of the master unit 4 is not operated, it is determined whether the call / response button 10e of another indoor unit 10 is operated (step S216) If the answer to the determination is yes, the main unit 4 transmits a response signal to the called indoor child device (step S218), and the called indoor child device 10 and the called indoor child device 10 communicate with each other. A communication path is formed between them via the base unit 4 (step S220). Then, step S210 and subsequent steps are executed.

このように子機間通話においても、通話終了の指示が与えられるか、或いは通話が行われていても所定時間が経過すると、自動的に通話が終了する。   As described above, even in a call between slave units, an instruction to end a call is given, or a call is automatically ended when a predetermined time elapses even if the call is made.

ステップＳ２１６の判断の答えがノーの場合には、規定呼出時間が経過したか判断し（ステップＳ２２２）、その判断の答えがノーの場合には、ステップＳ２０４から再び実行する。この判断の答えがイエスの場合には、親機４及び室内子機１０は待機状態に戻る（ステップＳ２２４）。   If the answer to the determination in step S216 is no, it is determined whether the specified call time has elapsed (step S222). If the answer to the determination is no, the process is executed again from step S204. If the answer to this determination is yes, the master unit 4 and the indoor unit 10 return to the standby state (step S224).

親機４と室内子機１０とが通話しているとき、または親機４を介して室内子機１０同士が通話しているとき、室内子機同士の通話にこのインターホンが使用可能な周波数帯が使用されているので、パニック釦１２または室内子機１０において通報／停止釦１０ｄが操作されたものからの緊急呼出や、センサ子機８からの侵入者検知の呼び出しに、親機４は応答することができない。そこで、上述したように、親機４と室内子機１０との通話時間、親機４を介しての子機１０同士の通話の時間は一定時間例えば１分（パニック釦８やセンサ子機８の第１の時間に等しい時間）に制限されており、かつ図２及び図３に示したように、パニック釦１２等やセンサ子機８は、親機４から応答が無くても親機４に対して再度呼び出しを自動的に第１の時間経過後及び第２の時間経過後に掛けて、パニック釦１２等やセンサ子機８からの親機の呼出が成功するように構成している。   When the base unit 4 and the indoor unit 10 are talking, or when the indoor unit 10 is talking via the base unit 4, a frequency band in which this interphone can be used for a call between the indoor units. Is used, the master unit 4 responds to an emergency call from the panic button 12 or the indoor slave unit 10 in which the notification / stop button 10d is operated or an intruder detection call from the sensor slave unit 8. Can not do it. Therefore, as described above, the call time between the parent device 4 and the indoor child device 10 and the call time between the child devices 10 via the parent device 4 are, for example, a certain time (for example, the panic button 8 or the sensor child device 8). 2, and the panic button 12 and the sensor slave unit 8 can be connected to the master unit 4 even if there is no response from the master unit 4, as shown in FIGS. 2 and 3. The call is automatically repeated after the first time and the second time, so that the call of the parent device from the panic button 12 or the like or the sensor slave unit 8 is successful.

上記の実施の形態では、センサ子機８に使用するセンサについて具体的に記載しなかったが、種々のものを使用することができる。例えば家屋の所定箇所のドアや窓が開かれたことを検出するセンサを使用したり、特定の箇所に人が入ったことを検知するセンサを使用したりすることができる。   In said embodiment, although the sensor used for the sensor subunit | mobile_unit 8 was not described concretely, a various thing can be used. For example, it is possible to use a sensor that detects that a door or window at a predetermined location of a house has been opened, or a sensor that detects that a person has entered a specific location.
