Description

本発明は、家屋周りの屋外に不審者が存在することを検知したときに、屋内に配置された照明器具を自動的に点灯させることにより、屋内の居住者に対し不審者の通報を行う照明制御システムに関する。   The present invention automatically lights a lighting device arranged indoors when it is detected that a suspicious person exists outdoors around a house, thereby making a suspicious person's report to an indoor resident It relates to the control system.

従来の屋外に設置された所定の検知エリア内での人の在否に基づいて照明器具の点灯状態を制御するようにした照明制御システムとしては、同じ検知エリアで来客と不審者とを識別し、不審者を検知すると照明器具を自動的に点灯させるようにしたものが知られている（特許文献１参照）。これらの照明制御システムでは、屋外に設けられた人感センサと、人感センサによる検出信号を基に屋内外に配置された照明器具の点灯を制御するコントローラとを備え、コントローラは、人感センサによる人検知状態の時間当たりの回数又は１回分の検知時間が予め設定されたスレッシュレベルを超えたときに、屋内に配置された照明器具を点灯させるように構成されている。
特開平５−１０９４８６号公報 A conventional lighting control system that controls the lighting state of a lighting fixture based on the presence or absence of a person in a predetermined detection area installed outdoors can identify a visitor and a suspicious person in the same detection area. In addition, a device that automatically turns on a lighting fixture when a suspicious person is detected is known (see Patent Document 1). These lighting control systems include a human sensor provided outdoors, and a controller that controls lighting of a lighting fixture arranged indoors and outdoors based on a detection signal from the human sensor. When the number of times per person in the human detection state by 1 or the detection time for one time exceeds a preset threshold level, the lighting device arranged indoors is lit.
Japanese Patent Laid-Open No. 5-109486

上述したような照明制御システムにおいては、人感センサの周囲温度の変化に応じたスレッシュレベルの調整機能を有しないために、季節変化に基づく人感センサの周囲温度による性能変動により、不審者検出の精度を維持することが難しい。また、人感センサが、玄関口や勝手口などの出入口付近の天井部分に配置されるために、不審者に対する威嚇が行われ、不審者に対する刺激がかえって不審行動を助長させることがある。   Since the lighting control system as described above does not have a function of adjusting the threshold level according to the change in the ambient temperature of the human sensor, the suspicious person is detected due to the performance variation due to the ambient temperature of the human sensor based on the seasonal change. It is difficult to maintain accuracy. In addition, since the human sensor is arranged on the ceiling near the entrance / exit such as the entrance and the doorway, threatening the suspicious person is performed, and the suspicious person may be stimulated to promote suspicious behavior.

本発明は、上記従来の問題を解決するためになされたものであり、季節変化に基づく人感センサの周囲温度による性能変動を排除して、不審者検出の精度を維持することができ、また、大掛かりなカメラを露出して設置する場合等に比べて、不審者を刺激することが少ない照明制御システムを提供することを目的とする。   The present invention has been made to solve the above-described conventional problems, can eliminate performance fluctuations due to the ambient temperature of the human sensor based on seasonal changes, and maintain the accuracy of suspicious person detection. It is an object of the present invention to provide an illumination control system that does not irritate a suspicious person compared to a case where a large camera is exposed and installed.

上記目的を達成するために請求項１の発明は、屋外に設けられた人感センサと、前記人感センサによる検出信号を基に屋内外に配置された照明器具の点灯を制御するコントローラとを備え、前記コントローラは、前記人感センサによる人検知状態の時間当たりの回数又は１回分の検知時間が予め設定されたスレッシュレベルを超えたときに、不審者通報モードに入り、屋内に配置された照明器具を点灯させる照明制御システムにおいて、前記コントローラに設定されるスレッシュレベルは、前記人感センサの周囲温度の変化に応じて、自動又は手動により調整自在とされており、前記人感センサは、屋外に設けられた照明器具のセンサ取付部に取り付けられるものである。   In order to achieve the above object, the invention of claim 1 includes a human sensor provided outdoors, and a controller for controlling lighting of a lighting fixture arranged indoors and outdoors based on a detection signal from the human sensor. The controller is placed indoors in a suspicious person notification mode when the number of times per person detected by the human sensor or the detection time for one time exceeds a preset threshold level. In a lighting control system for lighting a lighting fixture, a threshold level set in the controller is adjustable automatically or manually according to a change in ambient temperature of the human sensor, It is attached to the sensor attachment part of the lighting fixture provided outdoors.

請求項１の発明によれば、コントローラに設定されるスレッシュレベルは、人感センサの周囲温度の変化に応じて自動又は手動により調整することができるので、季節変化に基づく人感センサの周囲温度による性能変動を排除して、不審者検出の精度を維持することができる。また、人感センサは、屋外に設けられた照明器具のセンサ取付部に取り付けられるので、照明器具の外観からその存在を直ちに確認することができず、大掛かりなカメラを露出して設置する場合等に比べて、不審者を刺激することが少ない。   According to the first aspect of the present invention, since the threshold level set in the controller can be adjusted automatically or manually according to the change in the ambient temperature of the human sensor, the ambient temperature of the human sensor based on the seasonal change. Therefore, the accuracy of suspicious person detection can be maintained. In addition, since the presence sensor is attached to the sensor mounting portion of a lighting fixture provided outdoors, its presence cannot be immediately confirmed from the appearance of the lighting fixture, and when a large camera is exposed and installed, etc. Compared to suspicious people, it is less irritating.

（第１の実施形態）
本発明の第１の実施形態に係る照明制御システムについて図１及び図２を参照して説明する。照明制御システム１は、人感センサ２１を有した照明器具２と、人感センサ２１による検出信号を基にシステム全体を制御するコントローラ３と、人感検知を居住者に報知する機能を持つ報知用器具４と、を備える。照明器具２は屋外に配置され、コントローラ３と報知用器具４は屋内に配置される。報知用器具４としては、この例では屋内の照明器具を用いているが、この例に限られない。 (First embodiment)
A lighting control system according to a first embodiment of the present invention will be described with reference to FIGS. 1 and 2. The lighting control system 1 includes a lighting fixture 2 having a human sensor 21, a controller 3 that controls the entire system based on a detection signal from the human sensor 21, and a notification having a function of notifying a resident of human detection. Instrument 4. The lighting fixture 2 is arranged outdoors, and the controller 3 and the notification appliance 4 are arranged indoors. As the notification device 4, an indoor lighting device is used in this example, but is not limited to this example.

照明器具２は、該器具のセンサ取付部に取り付けられた人感センサ２１と、人感センサ２１による人の検知をトリガにして検出信号の送信制御を行う制御部２２と、赤外線、ＲＦ、又は有線などで検出信号をコントローラ３の受信部３１に向けて送信する送信部２３と、人感センサ２１の検知とは独立し、一般の点灯制御を行う負荷２４と、を備える。負荷２４としては、例えば、ランプや蛍光灯等が挙げられるが、この例に限られない。   The luminaire 2 includes a human sensor 21 attached to a sensor mounting portion of the fixture, a control unit 22 that performs transmission control of a detection signal using human detection by the human sensor 21 as a trigger, and infrared, RF, or A transmission unit 23 that transmits a detection signal to the reception unit 31 of the controller 3 by wire or the like, and a load 24 that performs general lighting control independent of the detection of the human sensor 21 are provided. Examples of the load 24 include a lamp and a fluorescent lamp, but are not limited to this example.

コントローラ３は、照明器具２の送信部２３から送信される検知信号を受信する受信部３１と、受信部３１で受信した検知信号の受信時刻を計る計時部３２と、受信部３１で受信した検出信号と計時部３２で計った受信時刻を基に報知用器具４の点灯を制御する制御部３３と、制御部３３での制御に際し使用されるスレッシュレベルの設定、調整等を行う調整部３４とを備える。調整部３４としては、例えば、調整ツマミやディップスイッチを用いてレベル設定を切替える。   The controller 3 includes a reception unit 31 that receives a detection signal transmitted from the transmission unit 23 of the lighting fixture 2, a time measuring unit 32 that measures a reception time of the detection signal received by the reception unit 31, and a detection received by the reception unit 31. A control unit 33 that controls lighting of the notification instrument 4 based on the signal and the reception time measured by the time measuring unit 32; and an adjustment unit 34 that performs setting, adjustment, and the like of a threshold level used in the control by the control unit 33; Is provided. As the adjustment unit 34, for example, the level setting is switched using an adjustment knob or a dip switch.

上記のように構成された本実施形態のシステム全体の動作について次に説明する。照明器具２の人感センサ２１が人を検知すると、送信部２３は、制御部２２からの指示により、検出信号をコントローラ３の受信部３１に向けて送信する。一方で、制御部２２は、人感センサ２１の検知とは独立した一般の制御信号を基に、負荷２４の点灯を制御する。これにより、コントローラ３が検出信号を受信するに際し、不審者を不要意に刺激することがない。   Next, the operation of the entire system of the present embodiment configured as described above will be described. When the human sensor 21 of the lighting fixture 2 detects a person, the transmission unit 23 transmits a detection signal to the reception unit 31 of the controller 3 in accordance with an instruction from the control unit 22. On the other hand, the control unit 22 controls the lighting of the load 24 based on a general control signal independent of the detection of the human sensor 21. Thereby, when the controller 3 receives a detection signal, a suspicious person is not stimulated unnecessarily.

コントローラ３の受信部３１が検知信号を受信すると、制御部３３は計時部３２により受信時刻の記録を行い、検知信号と受信時刻を基に不審者の判定を行なう。人検知状態の所定の時間当たりの回数が予め設定されたスレッシュレベルを超えたときに、不審者と判定し、判定した不審者情報を記録し、報知用器具４を点灯させる。   When the receiving unit 31 of the controller 3 receives the detection signal, the control unit 33 records the reception time by the time measuring unit 32, and determines the suspicious person based on the detection signal and the reception time. When the number of human detection states per predetermined time exceeds a preset threshold level, the person is determined to be a suspicious person, the determined suspicious person information is recorded, and the notification instrument 4 is turned on.

下記表１は、１日の時間帯毎の、人検出状態の時間、例えば６０秒当たりの回数に対する予め設定されたスレッシュレベルを示す。該スレッシュレベルは、例えば、季節や人感センサの周囲温度等に応じたテーブルとしてプログラムされており、調整部３４で切替え操作することで、簡単に調整することができる。人通りの少ない時間帯には、該スレッシュレベルを小さく設定することで、不審者をより的確に判定でき、人通りの多い時間帯には、該スレッシュレベルを大きく設定することで、通行人、来客等による不審者との判定を減らすことができる。

Figure 2008084588
Table 1 below shows preset threshold levels with respect to the time in the human detection state, for example, the number of times per 60 seconds, for each time slot of the day. The threshold level is programmed as, for example, a table according to the season, the ambient temperature of the human sensor, and the like, and can be easily adjusted by switching the adjustment unit 34. By setting the threshold level small during busy hours, the suspicious person can be determined more accurately, and by setting the threshold level large during busy hours, passers-by, It is possible to reduce the judgment of a suspicious person by a visitor or the like.
Figure 2008084588

なお、照明器具２が温度センサを備えることで、制御部２２は検知信号を基にスレッシュレベルを自動調整することも可能である。   In addition, when the lighting fixture 2 is provided with a temperature sensor, the control part 22 can also adjust a threshold level automatically based on a detection signal.

（第２の実施形態）
本発明の第２の実施形態に係る照明制御システムについて、図３を参照して説明する。照明制御システム１は、コントローラ３に人検知状態の所定の時間当たり回数に対するスレッシュレベルに学習機能を備える点で第１の実施形態と異なる。 (Second Embodiment)
An illumination control system according to a second embodiment of the present invention will be described with reference to FIG. The lighting control system 1 is different from the first embodiment in that the controller 3 has a learning function at a threshold level for a predetermined number of times of human detection state.

具体的には、所定の時間帯毎での、人検知状態の所定の時間当たりの回数を、日、曜日、月の毎に記憶し、記憶した回数の平均値を基にスレッシュレベルの設定を行う。これにより、不審者を判定する精度を上げることができる。   Specifically, the number of human detection states per predetermined time period is stored for each day, day of the week, and month, and the threshold level is set based on the average value of the stored times. Do. Thereby, the precision which determines a suspicious person can be raised.

（第３の実施形態）
本発明の第３の実施形態に係る照明制御システムについて、図４を参照して説明する。照明制御システム１は、照明器具２に温度センサ２５を備える点で第１及び第２の実施形態と異なる。 (Third embodiment)
An illumination control system according to a third embodiment of the present invention will be described with reference to FIG. The lighting control system 1 differs from the first and second embodiments in that the lighting fixture 2 includes a temperature sensor 25.

人感センサ２１は、赤外線などを利用して、周囲温度と温度差のあるものが検知エリア内で動いたときに、その温度変化を検知する仕組みになっている。また、図５で示されるように、人感センサ出力がＨｉｇｈのとき非検知、Ｌｏｗのとき検知とした場合には、Ｌｏｗ出力が開始してから次にＨｉｇｈ出力になるまでの時間が検知時間となる。周囲温度が高くなると、人の体温との温度差が少なくなり、人が居ても人感センサ出力に現れにくくなるため、短い検知時間でも検知とみなすことで、検知し易くすればよい。   The human sensor 21 uses an infrared ray or the like to detect a temperature change when an object having a temperature difference from the ambient temperature moves within the detection area. Further, as shown in FIG. 5, when the human sensor output is high, non-detection is detected, and when the human sensor output is low, the time from the start of low output to the next high output is detected time. It becomes. When the ambient temperature increases, the temperature difference from the human body temperature decreases, and even if there is a person, it becomes difficult to appear in the human sensor output. Therefore, it can be easily detected by regarding the detection even in a short detection time.

本実施形態においては、照明器具２が温度センサ２５を備えているので、制御部３３に向けて送信する検知信号には、検知があったという情報と、検知時間の情報と、周囲温度の情報と、が含まれる。制御部３３は、検知時間が予め設定されたスレッシュレベルを超えたときに、１回分の人検知状態と判定する。該スレッシュレベルは、人感センサの周囲温度に応じたテーブルとしてプログラムされており、制御部３３にて自動調整される。また、調整部３４で切替え操作することで、手動調整も可能である。具体的には周囲温度と人の体温との温度差が小さい、例えば夏季には、短い検知時間でも検知とみなす判定を行い、温度差が大きい、例えば冬季には、比較的長い時間で検知とみなす判定を行う。例えば、図５において、Ｔ１が冬季、Ｔ２は春季及び秋季、Ｔ３が夏季として表される。これにより、季節変化に基づく人感センサ２１の周囲温度による性能変動を排除して、不審者検出の精度を維持することができる。   In the present embodiment, since the lighting fixture 2 includes the temperature sensor 25, the detection signal transmitted to the control unit 33 includes information that detection has occurred, detection time information, and ambient temperature information. And are included. When the detection time exceeds a preset threshold level, the control unit 33 determines that the human detection state is for one time. The threshold level is programmed as a table corresponding to the ambient temperature of the human sensor, and is automatically adjusted by the control unit 33. Further, manual adjustment is also possible by switching operation with the adjustment unit 34. Specifically, the temperature difference between the ambient temperature and the human body temperature is small.For example, in summer, the detection is performed even if the detection time is short. Judgment is made. For example, in FIG. 5, T1 is represented as winter, T2 is represented as spring and autumn, and T3 is represented as summer. Thereby, the performance variation by the ambient temperature of the human sensor 21 based on a seasonal change can be excluded, and the accuracy of suspicious person detection can be maintained.

（第４の実施形態）
本発明の第４の実施形態に係る照明制御システムについて、図６を参照して説明する。照明制御システム１は、照明器具２を複数備える点で他の実施形態と異なる。 (Fourth embodiment)
An illumination control system according to a fourth embodiment of the present invention will be described with reference to FIG. The lighting control system 1 is different from the other embodiments in that it includes a plurality of lighting fixtures 2.

本実施形態においては、複数ある照明器具２のうち、一方の照明器具２の人感センサ２１が人を検知すると、送信部２３は、制御部２２からの指示により、検出信号をコントローラ３の受信部３１に向けて送信する。コントローラ３の受信部３１が複数の検知信号を受信すると、制御部３３は計時部３２により受信時刻の記録を行い、検知信号と受信時刻を基に不審者の判定を行なう。人検知状態の所定の時間当たりの回数が予め設定されたスレッシュレベルを超えたときに、不審者と判定し、判定した不審者情報を記録し、報知用器具４を点灯させる。さらに、複数ある照明器具２のうち、２機以上の照明器具２の人感センサ２１が予め設定した時間内に連続して人を検知した場合、検知信号と受信時刻を基に要注意の不審者の判定を行なう。人検知状態の所定の時間当たりの合計回数が、該スレッシュレベルとは異なる、予め設定されたスレッシュレベルを超えたときに、不審者と判定し、判定した不審者情報を記録し、報知用器具４を点灯させる。これにより、不審者がとる可能性の高い行動を検出し、不審者を判定する精度を上げることができる。   In the present embodiment, when the human sensor 21 of one of the plurality of lighting fixtures 2 detects a person, the transmission unit 23 receives a detection signal from the controller 3 according to an instruction from the control unit 22. Transmit to the unit 31. When the receiving unit 31 of the controller 3 receives a plurality of detection signals, the control unit 33 records the reception time by the time measuring unit 32 and determines the suspicious person based on the detection signal and the reception time. When the number of human detection states per predetermined time exceeds a preset threshold level, the person is determined to be a suspicious person, the determined suspicious person information is recorded, and the notification instrument 4 is turned on. Furthermore, when the human sensor 21 of two or more lighting fixtures 2 detects a person continuously within a preset time among a plurality of lighting fixtures 2, a suspicious caution is required based on the detection signal and the reception time. The person is judged. When the total number of human detection states per predetermined time exceeds a preset threshold level different from the threshold level, it is determined that the person is a suspicious person, the determined suspicious person information is recorded, and a notification device 4 is lit. As a result, it is possible to detect an action likely to be taken by a suspicious person and improve the accuracy of determining the suspicious person.

なお、本発明は、上記各種実施形態の構成に限られることなく、発明の趣旨を変更しない範囲で種々の変形が可能である。例えば、人検知状態の所定の時間当たりの回数に対するスレッシュレベルを数段階に分けて設定し、該回数が該スレッシュレベルを超えたときに、不審者を判定するものであってよい。   The present invention is not limited to the configurations of the various embodiments described above, and various modifications can be made without changing the spirit of the invention. For example, the threshold level with respect to the number of times of the human detection state per predetermined time may be set in several stages, and the suspicious person may be determined when the number of times exceeds the threshold level.
