以下、本発明の実施形態を図面に基づいて説明する。図1に示すインターホンシステム1は、来訪者が操作する玄関子機11と、居住者が操作するインターホン親機21とから構成されている。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. The intercom system 1 shown in FIG. 1 includes an entrance handset 11 operated by a visitor and an interphone base unit 21 operated by a resident.

玄関子機11には、子機全体の動作を制御する子機CPU12と、来訪者を含む玄関周辺を撮影するためのカメラ13と、来訪者が居住者を呼び出すための呼出ボタン14と、来訪者が居住者との通話に使用する子機マイク15および子機スピーカ16と、夜間など玄関子機11の周辺が暗いときに点灯する照明灯としての白色LED17と、子機CPU12がインターホン親機21と通信するための子機I/F18とが設けられている。なお、白色LED17は、玄関子機11周辺の明るさを検出する照度センサ(図示略)、または子機CPU12の時計機能を用いて点灯させることができる。   The entrance slave unit 11 includes a slave unit CPU 12 for controlling the operation of the entire slave unit, a camera 13 for photographing the vicinity of the entrance including the visitor, a call button 14 for the visitor to call a resident, and a visitor. Handset microphone 15 and handset speaker 16 used by a person for a call with a resident, white LED 17 as an illuminating lamp that lights when the periphery of the entrance handset 11 is dark such as at night, and the handset CPU 12 is an interphone base unit A slave I / F 18 for communicating with 21 is provided. The white LED 17 can be turned on using an illuminance sensor (not shown) for detecting the brightness around the entrance slave unit 11 or a clock function of the slave unit CPU 12.

インターホン親機21には、親機全体の動作を制御するための親機CPU22と、玄関子機11のカメラ13が撮影した映像を出画するモニタ23と、居住者が来訪者との通話に使用する親機音声部24と、居住者が来訪者との通話を開始する際に操作する通話ボタン25と、居住者が玄関子機11に設けられた白色LED17の明るさを変更設定するために操作する操作部26と、居住者が外部に異常を知らせるために操作する異常報知部27と、親機CPU22が玄関子機11と通信するための親機I/F28とが設けられている。   The interphone master unit 21 includes a master CPU 22 for controlling the operation of the entire master unit, a monitor 23 for displaying images taken by the camera 13 of the front door slave unit 11, and a resident for a call with a visitor. In order to change and set the brightness of the main unit voice unit 24 to be used, the call button 25 operated when the resident starts a call with the visitor, and the white LED 17 provided on the entrance cordless handset 11 by the resident. Are provided with an operation unit 26 operated by the resident, an abnormality notification unit 27 operated by a resident to notify the outside of the abnormality, and a main unit I / F 28 for the main unit CPU 22 to communicate with the entrance unit 11. .

次に、上記のように構成されたインターホンシステム1の動作について説明する。来訪者が玄関子機11の呼出ボタン14を押すと、子機CPU12が子機I/F18、親機I/F28を介して呼出信号を親機CPU22に送信する。図2に示すように、親機CPU22は、玄関子機11からの呼出信号を検出すると(S31)、モニタ23を起動し(S32)、モニタ23に玄関子機11のカメラ13が撮像した映像を出画させ、親機音声部24から呼出音を発生させ(S33)、居住者に来訪者の訪問を知らせる。   Next, the operation of the intercom system 1 configured as described above will be described. When a visitor presses the call button 14 of the entrance slave unit 11, the slave unit CPU 12 transmits a call signal to the master unit CPU 22 via the slave unit I / F 18 and the master unit I / F 28. As shown in FIG. 2, when the master CPU 22 detects a call signal from the entrance slave unit 11 (S31), it activates the monitor 23 (S32), and an image captured by the camera 13 of the entrance slave unit 11 on the monitor 23 Is displayed, a ringing tone is generated from the main unit voice unit 24 (S33), and the resident is informed of the visit of the visitor.

夜間など玄関子機11の周辺が暗いときには、子機CPU12が親機CPU22に照明要請を通知する。親機CPU22は、照明要請を受けると、白色LED17の明るさを段階的に変化させるための明るさ変更指令を子機CPU12に返信する。この実施形態の明るさ変更通知には、白色LED17を最大の明るさ(第1の明るさ)で点灯させる呼出時調光指令と、白色LED17を呼出時よりも暗い標準的な明るさ(第2の明るさ)で点灯させる通話時調光指令とが含まれている。   When the periphery of the entrance slave unit 11 is dark, such as at night, the slave unit CPU 12 notifies the master unit CPU 22 of a lighting request. When receiving the illumination request, the master CPU 22 returns a brightness change command for changing the brightness of the white LED 17 stepwise to the slave CPU 12. The brightness change notification of this embodiment includes a call-time dimming command for turning on the white LED 17 at the maximum brightness (first brightness), and a standard brightness (first brightness darker than that at the time of calling the white LED 17). Dimming command during a call to be lit at (brightness of 2).

そして、図2に示すように、玄関子機11から呼出信号を受信しているときに、親機CPU22は、照明要請を確認したのち(S34)、呼出時調光指令を子機CPU12に送信する(S35)。子機CPU12は、白色LED17への電源供給量が最大となるように玄関子機11の調光回路(図示略)を制御し、白色LED17を最大の明るさで点灯させる。なお、昼間など玄関子機11の周辺が充分に明るい場合は、子機CPU12が照明要請を通知しないため、親機CPU22は白色LED17を消灯させた状態で呼び出しに応答するための別処理に移行する(S40)。   Then, as shown in FIG. 2, when receiving a call signal from the entrance slave unit 11, the master unit CPU 22 confirms the illumination request (S34), and then transmits a dimming command for calling to the slave unit CPU 12 (S35). The subunit | mobile_unit CPU12 controls the light control circuit (illustration omitted) of the entrance subunit | mobile_unit 11 so that the power supply amount to white LED17 may become the maximum, and makes white LED17 light with the maximum brightness. When the surroundings of the entrance slave unit 11 is sufficiently bright such as in the daytime, the slave unit CPU 12 does not notify the lighting request, so the master unit CPU 22 shifts to another process for answering the call with the white LED 17 turned off. (S40).

続いて、居住者が通話ボタン25をONすると(S36)、親機CPU22は通話開始信号を子機CPU12に送信し、子機CPU12が子機マイク15を有効にするための制御を行う。そして、親機CPU22は、通話時調光指令を子機CPU12に送信し(S38)、子機CPU12は、白色LED17への電源供給量が予め設定された標準値となるように調光回路を制御し、白色LED17を標準的な明るさで点灯させる。その後、親機CPU22は、玄関子機11からの終話信号を確認し(S39)、処理を終了する。   Subsequently, when the resident turns on the call button 25 (S36), the master CPU 22 transmits a call start signal to the slave CPU 12, and the slave CPU 12 performs control for enabling the slave microphone 15. Then, the master unit CPU 22 transmits a dimming command during a call to the slave unit CPU 12 (S38), and the slave unit CPU 12 sets the dimming circuit so that the power supply amount to the white LED 17 becomes a preset standard value. The white LED 17 is lit with a standard brightness. Thereafter, the base unit CPU 22 confirms the end call signal from the entrance handset 11 (S39), and ends the process.

ここで、通話時調光指令が指定する白色LED17の標準的な明るさとは、居住者がインターホン親機21の操作部26で変更可能な明るさであり、例えば、モニタ23の映像が充分に見易く、しかも、来訪者が子機マイク4に近づいて通話しても眩しさを感じない程度の明るさを適宜に設定できる。また、呼出時調光指令が指定する白色LED17の明るさは、必ずしも調光回路の最大出力である必要はなく、呼出時の明るさと最大の明るさとの中間値を居住者が操作部26にて適宜に設定できる。   Here, the standard brightness of the white LED 17 specified by the dimming command during a call is the brightness that can be changed by the occupant using the operation unit 26 of the interphone master unit 21. For example, the image on the monitor 23 is sufficient. It is easy to see, and brightness can be set as appropriate so that the visitor does not feel dazzling even if he / she talks to the handset microphone 4. Further, the brightness of the white LED 17 specified by the dimming command at the time of calling does not necessarily have to be the maximum output of the dimming circuit. Can be set appropriately.

一方、居住者がインターホン親機21の異常報知部27を操作したときには、親機CPU22が子機CPU12に異常時調光指令を送信する。この異常時調光指令は、緊急を要するため、白色LED17を呼出時と同等の明るさまたはそれ以上に明るい明るさで点灯させる制御値を含み、この調光指令に応答し、子機CPU12は、白色LED17の輝度が最大またはその近くとなるように、玄関子機11の調光回路を制御する。   On the other hand, when the resident operates the abnormality notifying unit 27 of the interphone master device 21, the master CPU 22 transmits a light control command at the time of abnormality to the slave CPU 12. Since this abnormal-time dimming command is urgent, it includes a control value for turning on the white LED 17 with a brightness equivalent to or higher than that at the time of calling, and in response to the dimming command, the slave CPU 12 The dimming circuit of the entrance cordless handset 11 is controlled so that the luminance of the white LED 17 is at or near the maximum.

したがって、この実施形態のインターホンシステム1によれば、来訪者が居住者を呼び出したときに、呼出時調光指令により玄関子機11の白色LED17を相対的に明るく点灯させ、カメラ13の映像を鮮明にし、居住者にモニタ23の表示を見易くすることができ、居住者が通話ボタン25をONしたときには、通話時調光指令によって白色LED17を相対的に暗く点灯させ、来訪者が眩しさを感じることなく子機マイク15に接近して通話でき、さらに、居住者が異常報知部27を操作したときに、異常時調光指令によって白色LED17を最も明るく点灯させることができるなど、インターホン親機11からの多様な明るさ変更通知により、白色LED17の明るさを簡易に調整することができる。   Therefore, according to the intercom system 1 of this embodiment, when the visitor calls the resident, the white LED 17 of the entrance cordless handset 11 is lit relatively brightly by the dimming command at the time of calling, and the image of the camera 13 is displayed. The display of the monitor 23 can be made clear to the resident, and when the resident turns on the call button 25, the white LED 17 is turned on relatively darkly by the dimming command at the time of the call, and the visitor is made dazzling. The interphone master unit is capable of making a call close to the handset microphone 15 without feeling it, and further enabling the white LED 17 to be lit up most brightly by a dimming command when an occupant operates the abnormality notification unit 27. The brightness of the white LED 17 can be easily adjusted by various brightness change notifications from 11.

なお、本発明は、上記実施形態に限定されるものではなく、例えば、白色LED17に代えて黄色、赤色または青色LEDを含む各種の照明灯を使用するなど、発明の趣旨を逸脱しない範囲で、各部の構成または制御手順を適宜に変更して実施することも可能である。   Note that the present invention is not limited to the above-described embodiment. For example, various illumination lamps including yellow, red, or blue LEDs may be used in place of the white LEDs 17, and the scope of the invention is not deviated. It is also possible to change the configuration or control procedure of each part as appropriate.
