Description

この発明は、監視カメラを備えた防犯灯ポールを用いたネットワーク型緊急通報システムに関する。   The present invention relates to a network-type emergency call system using a security light pole equipped with a surveillance camera.

近年、路上強盗，引ったくり，誘拐などの犯罪が急増している。従来、このような社会問題に応えるべく、図６，７に示すような街頭の防犯灯に監視制御機器や通信機器を設け、ネットワークを介して監視センターに通報するようにしたネットワーク型緊急通報システムが提案されている（特許文献１，２参照）。すなわち、図６のように防犯灯ポール１ａ，１ｂに照明灯２ａ，２ｂと、緊急呼出しボタン３ａ，３ｂと、監視カメラ４ａ，４ｂとを含む警報機器と、図７のようにマイク１０ｃ，スピーカ１０ｄ，カメラ１０ｅ，モニタ表示部１０ｆを有し双方向の通話を可能にしたテレビインターホン１０とを備えている。   In recent years, crimes such as street robbery, snatching, and kidnapping are increasing rapidly. Conventionally, in order to respond to such social problems, a network-type emergency call system in which monitoring control devices and communication devices are provided in street crime prevention lights as shown in FIGS. 6 and 7 and the monitoring center is notified via the network. Has been proposed (see Patent Documents 1 and 2). That is, as shown in FIG. 6, the alarm lights including the crime prevention light poles 1a and 1b, the illumination lights 2a and 2b, the emergency call buttons 3a and 3b, and the monitoring cameras 4a and 4b, and the microphone 10c and the speaker as shown in FIG. 10d, a camera 10e, and a monitor interfacing unit 10f, and a TV intercom 10 that enables two-way communication.

さらに、テレビインターホン１０には、ＣＰＵなどからなり各部を制御する制御部１０ａと、マイク１０ｃ，スピーカ１０ｄによりインターホン通話を可能にする通話部１０ｂとを備えている。また、防犯灯ポール１ａ，１ｂには、ＣＰＵなどからなり防犯灯ポール１ａ，１ｂ全体の動作を制御する制御部１０１と、防犯灯監視制御サーバ１００（図６参照）を備えた監視センターとのネットワークＬを介する通信を制御する通信制御部１０２とを備えている。これによって、緊急呼出しボタン３ａ，３ｂが押下された場合、監視センターとの双方向通話を可能にするとともに、監視カメラ４ａ，４ｂで撮像された画像を監視センターのモニタに表示するようになっている。   Furthermore, the TV interphone 10 includes a control unit 10a that includes a CPU and controls each unit, and a call unit 10b that enables an interphone call using a microphone 10c and a speaker 10d. The security light poles 1a and 1b include a control unit 101 that includes a CPU and controls the entire operation of the security light poles 1a and 1b, and a monitoring center including the security light monitoring control server 100 (see FIG. 6). And a communication control unit 102 that controls communication via the network L. As a result, when the emergency call buttons 3a and 3b are pressed, two-way communication with the monitoring center is made possible and images taken by the monitoring cameras 4a and 4b are displayed on the monitor of the monitoring center. Yes.

また、図７のように、防犯灯ポール１ａ，１ｂには音響センサ５０が設けられ、音響センサ５０が人の叫び声や事故などの音を感知したときには、防犯灯監視制御サーバ１００を呼出し、防犯灯監視制御サーバ１００からの指令に基づいて警報機器を自動的に作動させることができる。また、緊急呼出しボタン３ａが押下された場合、近接する防犯灯ポール１ｂの監視カメラ４ｂを、緊急呼出しボタン３ａが押下された防犯灯ポール１ａ側に振り向けることも可能である。   As shown in FIG. 7, the security light poles 1a and 1b are provided with an acoustic sensor 50. When the acoustic sensor 50 senses a sound of a person screaming or an accident, the security light monitoring control server 100 is called to The alarm device can be automatically activated based on a command from the lamp monitoring control server 100. When the emergency call button 3a is pressed, the monitoring camera 4b of the adjacent security light pole 1b can be turned to the security light pole 1a side where the emergency call button 3a is pressed.

ところで、街頭の騒音には交通騒音や工事音、公園や小学校の校庭では子供の遊ぶ叫び声などのさまざまな音があり、これらの中から犯罪に関わる叫び声や事故音を感知することは極めて難しく、単にレベルの大きさだけで判断すると警報機器が頻繁に誤動作する原因ともなる。
また、緊急呼出しボタン３ａが押下された場合、近接する防犯灯ポール１ｂの監視カメラ４ｂを、緊急呼出しボタン３ａが押下された防犯灯ポール１ａ側の方に振り向けるものでは、防犯灯ポール１ａの近くで起きる犯罪には有効であるが、そこから少し離れた場所で発生する犯罪に対しては、緊急呼出しボタンを操作するまでに時間が掛かり、効果が薄くなる。 By the way, street noise includes various sounds such as traffic noise and construction sounds, and children's screams in parks and elementary schools. Judging by the size of the level alone may cause the alarm device to malfunction frequently.
When the emergency call button 3a is pressed, the surveillance camera 4b of the adjacent security light pole 1b is turned toward the security light pole 1a where the emergency call button 3a is pressed. It is effective for crimes that occur nearby, but for crimes that occur slightly away from it, it takes time to operate the emergency call button, and the effect is reduced.

さらに、夜間に防犯灯ポール１ａ，１ｂから少し離れて暗闇になるような場所での犯罪に対しては、監視カメラ４ａ，４ｂの撮像画像が見づらくなるという問題がある。
したがって、この発明の課題は、特に地域防犯協会や警察署などが普及活動を推進している、防犯ブザーや防犯警笛等の特定音に対して警報機器を作動させるようにするとともに、その発生音の方向に監視カメラおよび投光器を振り向けることができる緊急通報システムを提供することにある。 Furthermore, there is a problem that it is difficult to see the images captured by the monitoring cameras 4a and 4b for crimes in a place that is a little away from the security light poles 1a and 1b at night.
Therefore, an object of the present invention is to activate an alarm device for a specific sound such as a security buzzer or a security whistle, which is promoted by a local crime prevention association or police station, etc. It is an object of the present invention to provide an emergency call system capable of directing a surveillance camera and a projector in the direction of.

このような課題を解決するため、請求項１の発明では、照明灯と緊急呼出しボタンと監視カメラとを含む警報機器と、マイクおよびスピーカを有するインターホンとを少なくとも備えた防犯灯ポールと、前記警報機器を制御する防犯灯監視制御サーバを有する監視センターとをネットワークに接続して構成される緊急通報システムにおいて、
前記防犯灯ポールに警報機器としての投光器と、複数個の音響センサと特定音検知器と音源位置検出器とからなり音源位置または方角の少なくとも一方を検出する周囲音検出装置とを設けたことを特徴とする。 In order to solve such a problem, in the invention of claim 1, an alarm device including an illuminating lamp, an emergency call button, and a monitoring camera, a security light pole including at least an interphone having a microphone and a speaker, and the alarm In an emergency call system that is configured by connecting to a network with a surveillance center having a security light monitoring control server that controls the device,
The crime prevention light pole is provided with a projector as an alarm device, and a surrounding sound detection device that includes a plurality of acoustic sensors, a specific sound detector, and a sound source position detector that detects at least one of a sound source position or a direction. Features.

上記請求項１の発明においては、前記特定音は、防犯ブザー，防犯警笛を含む防犯用器具に関するものであることができ（請求項２の発明）、請求項１または２の発明においては、前記監視カメラおよび投光器を上下，水平方向に旋回可能にすることができ（請求項３の発明）、請求項１〜３のいずれかの発明においては、前記防犯灯ポールは、前記緊急呼出しボタンの操作時のほか、前記特定音を検知したときに前記警報機器を作動させることができる（請求項４の発明）。   In the invention of claim 1, the specific sound can relate to a security device including a security buzzer and a security horn (invention of claim 2). In the invention of claim 1 or 2, The surveillance camera and the projector can be turned in the vertical and horizontal directions (invention of claim 3), and in the invention of any one of claims 1 to 3, the security light pole operates the emergency call button. In addition to time, the alarm device can be activated when the specific sound is detected (invention of claim 4).

請求項１〜４のいずれかの発明においては、前記周囲音検出装置で検出された特定音の発生位置または発生方角に、前記防犯灯ポールの監視カメラを振り向けることができ（請求項５の発明）、また、請求項１〜５のいずれかの発明においては、前記周囲音検出装置で検出された特定音の発生位置または発生方角に、前記防犯灯ポールの投光器を振り向けることができる（請求項６の発明）。   In the invention according to any one of claims 1 to 4, the security light pole monitoring camera can be directed to the generation position or direction of the specific sound detected by the ambient sound detection device. (Invention) In the invention of any one of claims 1 to 5, the projector of the security light pole can be directed to the generation position or direction of the specific sound detected by the ambient sound detection device ( Invention of Claim 6).

請求項１〜４の発明によれば、防犯に関わる特定音を検出して警報機器を自動的に作動させるようにしたので、人の叫び声や事故等で自動作動する従来方式より、間違った判断による自動作動の回数を著しく低減させることができる。また、防犯灯ポールから離れた位置で発生した犯罪に対し、スピーカによる警報鳴動や回転赤色灯の点灯などをタイムリーに行なうことができ、犯罪を未然に防止できる効果がある。   According to the inventions of claims 1 to 4, since the alarm device is automatically activated by detecting a specific sound related to crime prevention, it is erroneously judged from the conventional method that automatically activates when a person screams or accidents occur. The number of automatic operations can be significantly reduced. Further, for crimes occurring at a position away from the crime prevention light pole, an alarm can be sounded by a speaker, a rotating red light can be turned on in a timely manner, and the crime can be prevented in advance.

また、請求項５の発明によれば、特定音の発生位置に監視カメラを振り向けることができるので、防犯灯ポールから離れた位置で発生した緊急事態も確実に撮像することができる。さらに、請求項６の発明によれば、特定音の発生位置に投光器を振り向けることができるので、防犯灯ポールから離れた暗闇などで起きた緊急事態も確実に撮像することができ、監視センターでの監視もより正確になる。なお、投光器は３０〜４０ｍ程度の遠方照射が可能なものが望ましい。   According to the invention of claim 5, since the surveillance camera can be directed to the position where the specific sound is generated, it is possible to reliably image an emergency situation that occurs at a position away from the security light pole. Furthermore, according to the invention of claim 6, since the projector can be directed to the position where the specific sound is generated, it is possible to reliably capture an emergency situation that occurred in the dark away from the crime prevention light pole. Monitoring at will also be more accurate. In addition, it is desirable for the projector to be able to irradiate a distance of about 30 to 40 m.

And a sound source position detector 30 comprising: Here, one acoustic sensor M1, M2, M3, and M4 of the security light pole 1 is attached to each of the X, Y, and Z axes including the origin of the three-dimensional coordinate system as shown in FIG.

動作について、説明する。
まず、防犯灯ポール１の周囲音検出装置では、音響センサＭ１，Ｍ２，Ｍ３，Ｍ４によって防犯灯ポール１付近の騒音を常時連続して計測しており、計測された音響信号は全て特定音検知器２０の信号整形器２１に入力される。信号整形器２１では、Ａ／Ｄ変換，フィルタ処理など所要の整形処理を行ない、記憶器２２に記憶する。記憶器２２は上書き可能なＦＩＦＯ（Ｆａｓｔ ｉｎ Ｆａｓｔ ｏｕｔ：先入れ先出し）方式により所定時間の音響信号を記憶するとともに、予め設定されたしきい値との比較を行ない、音響センサＭ１，Ｍ２，Ｍ３，Ｍ４からの音響信号の中で、どれか１つでもしきい値を超える信号が入力されると、その前後数秒間の音響信号を記憶器２２により記憶した後、記憶された代表的な音響信号を解析器２３に出力する。 The operation will be described.
First, in the ambient sound detection device for the crime prevention light pole 1, noises around the crime prevention light pole 1 are continuously measured by the acoustic sensors M1, M2, M3, and M4, and all the measured acoustic signals are detected as specific sounds. To the signal shaper 21 of the device 20. The signal shaper 21 performs necessary shaping processing such as A / D conversion and filter processing, and stores it in the storage device 22. The storage device 22 stores an acoustic signal for a predetermined time by an overwritable FIFO (Fast in First Out) method, and compares the acoustic signal with a preset threshold value, and performs acoustic sensors M1, M2, M3, and M4. When any one of the acoustic signals from the input signal exceeding the threshold is input, the storage unit 22 stores the acoustic signals for several seconds before and after that, and then stores the stored representative acoustic signals. Output to the analyzer 23.

解析器２３では、予め設定された特定音の特徴を抽出するための、周波数パターンや変動パターンなどを求める。図５に、防犯ブザーの動作音に対して１／３オクターブバンド成分でのレベルトレンドの例を示すが、概略０．１秒から０．２秒間の定常レベル定常周期で変動すること、音響レベル（オーバオール）の支配的な周波数成分は１ｋＨｚ〜５ｋＨｚ、図５はその一例として点線で示す４ｋＨｚ成分が支配的で、略２０ｄＢの一定レベル変動幅で変動すること、などが特徴である。このような防犯ブザーは、性格上日常の環境騒音には存在しないような音質であり、識別のための特徴的なパターン化が容易である。   The analyzer 23 obtains a frequency pattern, a fluctuation pattern, and the like for extracting the characteristics of a specific sound set in advance. FIG. 5 shows an example of a level trend in the 1/3 octave band component with respect to the operation sound of the security buzzer. The fluctuation of the steady level steady period of about 0.1 second to 0.2 second, the sound level The dominant frequency component of (overall) is 1 kHz to 5 kHz, and FIG. 5 is characterized in that, for example, the 4 kHz component indicated by the dotted line is dominant and fluctuates with a constant level fluctuation range of approximately 20 dB. Such a security buzzer has a sound quality that does not exist in daily environmental noise due to its nature, and can easily be formed into a characteristic pattern for identification.

解析器２３で求めた特徴的パターンはその後判定器２４に入力され、予め設定されている判定パターンと比較される。その結果、特定音と判断されると、記憶器２２に記憶された全音響信号を音源位置検出器３０の時間差演算器３１に入力する。時間差演算器３１では、包絡線処理やバンドパスフィルタ処理などにより、各音響信号のレベル増加位置を明瞭にした後、音響センサＭ１，Ｍ２，Ｍ３，Ｍ４に到達した特定音の時間差を求め、それと音響センサの配置関係に基づいて音源方角を求める。   The characteristic pattern obtained by the analyzer 23 is then input to the determiner 24 and compared with a preset determination pattern. As a result, when it is determined that the sound is a specific sound, all the sound signals stored in the storage device 22 are input to the time difference calculator 31 of the sound source position detector 30. The time difference calculator 31 clarifies the level increase position of each acoustic signal by envelope processing, bandpass filter processing, etc., and then obtains the time difference of the specific sound reaching the acoustic sensors M1, M2, M3, M4, and The sound source direction is obtained based on the arrangement relationship of the acoustic sensors.

図４に示す音響センサの配置で、各音響センサを等間隔に配置した場合の音源方角の算出方法は、例えば次式のようにする。
ｔａｎΦ＝τ１３／τ１２ …（１）
ｔａｎθ＝τ１４／√[（τ１２）2＋（τ１３）2] …（２）
ここに、τ１２，τ１３，τ１４はそれぞれ音響センサＭ２，Ｍ３，Ｍ４に対するＭ１への到達時間差（秒）であり、ΦはＭ１−Ｍ２を軸とする音源Ｐ点の方位角、θは仰角である。なお、到達時間差は音響センサ間の距離に関係し、離れているほど時間差が大きくなるため、音響信号の時間分解能を粗くできるが、実用的には数１０ｃｍ程度の間隔で充分である。音源の方角さえ分かれば発明の目的は達成できるが、音源から２個の音響センサへの到達時間差が一定であれば、音源の軌跡は双曲線になるという２次元上の理論を３次元上に展開することで、各双曲線の交点より音源位置の推定も可能である（必要ならば、特開２０００−０３５４７４号公報参照）。 In the arrangement of the acoustic sensors shown in FIG. 4, the calculation method of the sound source direction when the respective acoustic sensors are arranged at equal intervals, for example, is as follows.
tanΦ = τ13 / τ12 (1)
tan θ = τ14 / √ [(τ12) 2 + (τ13) 2 ] (2)
Here, τ12, τ13, and τ14 are arrival time differences (seconds) to M1 with respect to the acoustic sensors M2, M3, and M4, Φ is the azimuth angle of the sound source P point with M1-M2 as the axis, and θ is the elevation angle. . The arrival time difference is related to the distance between the acoustic sensors, and the time difference increases as the distance increases, so that the time resolution of the acoustic signal can be coarsened. However, an interval of about several tens of centimeters is sufficient in practice. If the direction of the sound source is known, the object of the invention can be achieved, but if the difference in arrival time from the sound source to the two acoustic sensors is constant, the two-dimensional theory that the locus of the sound source becomes a hyperbola is expanded in three dimensions. By doing so, it is also possible to estimate the sound source position from the intersection of each hyperbola (see JP 2000-035474 A if necessary).

音響センサの配置は図４のものに限らず、三角形や四角形の各コーナーに配置する方法もあり、音源位置（座標）を求めて方角を算出するようにしても良い。
以上のように音源位置検出器３０で求めた特定音の方角データは制御部１１に入力され、制御部１１からの制御信号に基づいてテレビインターホン１０と警報機器を作動させる。防犯ブザーなどの緊急音は比較的長い間作動するため、自動的に作動させることにより、監視センターでテレビインターホン１０からの音を聞くことができ、より正確な判断が可能になる。 The arrangement of the acoustic sensors is not limited to that shown in FIG. 4, and there is a method of arranging them at each corner of a triangle or a quadrangle, and the direction may be calculated by obtaining the sound source position (coordinates).
As described above, the direction data of the specific sound obtained by the sound source position detector 30 is input to the control unit 11, and the television interphone 10 and the alarm device are operated based on the control signal from the control unit 11. Since emergency sound such as a security buzzer operates for a relatively long time, by automatically operating it, the sound from the TV intercom 10 can be heard at the monitoring center, and more accurate judgment can be made.

警報機器の作動には、照明灯２によるライトアップの他に監視カメラ４，投光器５の作動と音源方向へのパン（カメラを首ふり状に回す撮影技法），チルト（カメラのレンズを上下方向に動かす撮影技法）動作などがある。これによって、緊急呼出しボタン３を押さなくても犯罪に関係する特定音を検出した場合は、警報機器を自動的に作動させることができる。また、カメラ１０ｅが内蔵されていないテレビインターホン１０で、緊急呼出しボタン３が押されたときは、制御部１１からの指令に基いて監視カメラ４がチルトダウンし、通報者を撮像するようになっている。なお、以上では、監視カメラ４と投光器５が別々に設けられる場合を説明したが、監視カメラ４に投光器５を内蔵させるようにしても良いものである。   For the operation of the alarm device, in addition to lighting up with the illumination lamp 2, the operation of the surveillance camera 4 and the projector 5 and the panning in the direction of the sound source (shooting technique that turns the camera around the neck) and tilt (the camera lens is moved up and down) Shooting techniques) As a result, when a specific sound related to a crime is detected without pressing the emergency call button 3, the alarm device can be automatically activated. When the emergency call button 3 is pressed on the TV intercom 10 that does not include the camera 10e, the surveillance camera 4 is tilted down based on a command from the control unit 11, and the caller is imaged. ing. In addition, although the case where the monitoring camera 4 and the projector 5 were provided separately was demonstrated above, you may make it make the monitoring camera 4 incorporate the projector 5.
