Description

監視カメラシステム及び監視カメラシステムを用いた監視方法Surveillance camera system and surveillance method using surveillance camera system
　本発明は、人や機器を監視する監視カメラシステム及び監視カメラシステムを用いた監視方法に関する。 The present invention relates to a monitoring camera system for monitoring people and devices and a monitoring method using the monitoring camera system.
　監視カメラシステムは、監視カメラで映像を時刻と紐づけて収録し、一定期間蓄積することができる。これにより、不審者の侵入や設備の異常動作を監視し、映像と紐づいている時刻にもとづいて、問題発生にかかわる状況整理や、異常発生の原因を解明するに役立つ。このような監視カメラシステムは、ネットワークを利用することにより、センタに映像を集約し、複数個所の監視を少ない人手で効率的に実施することが可能となっている。 The surveillance camera system can record video in association with time with the surveillance camera and store it for a certain period of time. As a result, intrusion of suspicious persons and abnormal operation of equipment are monitored, and it is useful for organizing the situation related to the occurrence of the problem and elucidating the cause of the abnormality based on the time linked to the video. Such a monitoring camera system can efficiently perform monitoring of a plurality of locations with a small number of people by using a network to collect video at a center.
　ネットワークの利用は、インターネット、スマートフォンなどの携帯端末の爆発的普及により、さまざまな活用形態が見出されている。インターネットは、電子メール、ホームページを代表とする人と人とのコミュニケーションのツールとなり、迅速な膨大な情報の共有を可能としている。さらに近年のネットワークの利用は、人とモノ、モノとモノとをつなげ、モノが本来もつ機能に付加的な機能を与える取組みが盛んである。いわゆるモノのインターネット「ＩｏＴ（Ｉｎｔｅｒｎｅｔ　ｏｆ　Ｔｈｉｎｇｓ）」である。 The use of networks has been found in various forms of use due to the explosive spread of mobile terminals such as the Internet and smartphones. The Internet has become a tool for communication between people such as e-mail and homepage, and enables rapid sharing of huge amounts of information. Furthermore, in recent years, the use of networks has been actively promoted to connect people and things, things and things, and add functions to the original functions of things. This is the so-called Internet of Things “IoT (Internet of Things)”.
　ＩｏＴを実現する主な技術は、センサを搭載した機器設備、そこで収集されるデータを分析する技術である。そのデータ分析技術は、ネットワークを通じて別途収集される様々なデータとクラウドと呼ばれる解析サーバーで連携することで、各々を最適とする制御、もしくは情報の提供が可能となってきている。 The main technology that realizes IoT is a technology that analyzes equipment collected with sensors and data collected there. The data analysis technology is capable of providing control or information that optimizes each of them by linking various data separately collected through a network with an analysis server called a cloud.
　ここで、センサのデータを効率よく収集し、ネットワークで伝送するかが議論となる。機器を監視する監視カメラを例にとると、画像に映る機器の状態に加えて、機器がさらされている環境データ（温度、湿度など）や駆動条件データ（電源の電圧、電流など）を同時に取り扱うことが、正確な状態監視をする上で望ましい。この場合、従来の技術では、監視カメラのデータ別途用意したデータ収録器でデータ化されたセンサ信号を別々に伝送し、解析サーバーで統合する常套的処置や、特許文献１（特開２００２－３００５６９号公報）に開示されているように、監視カメラの画像圧縮データ信号にセンサの信号データを重畳してネットワークで伝送する方法がある。 Here, it is debated whether to efficiently collect sensor data and transmit it over the network. Taking an example of a surveillance camera that monitors equipment, in addition to the state of the equipment shown in the image, environmental data (temperature, humidity, etc.) and driving condition data (power supply voltage, current, etc.) to which the equipment is exposed are simultaneously displayed. Handling is desirable for accurate state monitoring. In this case, in the conventional technique, a conventional procedure in which sensor signals converted into data by a data recorder separately prepared for the monitoring camera are separately transmitted and integrated by an analysis server, or Japanese Patent Laid-Open No. 2002-300569 is disclosed. As disclosed in Japanese Laid-open Patent Publication No. (Gazette), there is a method in which signal data of a sensor is superimposed on an image compression data signal of a surveillance camera and transmitted over a network.
特開２００２－３００５６９号公報JP 2002-300569 A
　しかしながら、上記特許文献１に記載の先行技術をＩｏＴの技術として利用するのに改良の余地がある。すなわち、監視カメラの画像データに紐づくセンサは、１つだけではなく、複数のセンサを扱うことができるようになることである。また、一度設置した監視カメラに対して、接続するセンサを変更したり、センサ数を変更したりするケースを想定する必要がある。 However, there is room for improvement in using the prior art described in Patent Document 1 as the IoT technology. That is, the number of sensors associated with the image data of the surveillance camera is not limited to one, and a plurality of sensors can be handled. In addition, it is necessary to assume a case where a sensor to be connected is changed or the number of sensors is changed with respect to a surveillance camera once installed.
　本発明は上記に鑑みてなされたものであり、ネットワーク網の変更や、伝送するデータの形態の変更をすることなく、接続するセンサを変更や、センサ数を変更することができる監視カメラシステムを提供することを目的とする。 The present invention has been made in view of the above, and provides a surveillance camera system that can change the number of sensors to be connected and the number of sensors without changing the network or changing the form of data to be transmitted. The purpose is to provide.

　本発明によれば、センサデータと紐づけて画像が取得できる監視カメラを、接続するセンサの変更や、センサ数の変更に対応した仕組みで提供でき、さらに、それら変更に対するネットワーク網や伝送データ形態の変更をすることなく、効率的なシステムを実現することができる。 According to the present invention, it is possible to provide a surveillance camera capable of acquiring an image linked with sensor data with a mechanism corresponding to a change in sensors to be connected or a change in the number of sensors, and further, a network network or transmission data form for the changes. An efficient system can be realized without making any changes.

For example, a magnetic sensor, a temperature sensor, a humidity sensor, a vibration sensor, an acceleration sensor, a strain sensor, a proximity sensor, a voice sensor, an ultrasonic sensor, a current sensor, There are voltage sensors, optical sensors, radiation sensors, and the like.
　例として、図２で図示しているように、被写体２であるプロペラ３０を回転させるモータ３１での利用形態を説明する。モータ３１はプロペラ３０を回転させており、プロペラ３０に欠陥などが生じると正常に起きない振動を呈することがある。この振動は、監視カメラ３の動画として検出するためには、高速カメラのような高価なデバイスで監視する必要がある。一方、振動センサや加速度センサは、比較して安価なデバイスであり、前述のような異常振動を感度よく検知できる。そこで、センサ５の信号と監視カメラ３の画像データを紐付けて監視するために、通常の画像内に、センサ信号を埋め込み、画像データとして取り扱う監視カメラシステム１が本実施例の概要である。 As an example, as shown in FIG. 2, a usage form in a motor 31 that rotates a propeller 30 that is a subject 2 will be described. The motor 31 rotates the propeller 30, and when the propeller 30 is defective or the like, vibration that does not occur normally may occur. In order to detect this vibration as a moving image of the monitoring camera 3, it is necessary to monitor it with an expensive device such as a high-speed camera. On the other hand, a vibration sensor and an acceleration sensor are inexpensive devices, and can detect abnormal vibration as described above with high sensitivity. Therefore, the monitoring camera system 1 that embeds a sensor signal in a normal image and handles it as image data to monitor the signal of the sensor 5 and the image data of the monitoring camera 3 is the outline of this embodiment.
　このような場合、従来、カメラデバイスと別途用意されたデータ収集系で、センサの信号データを収集し、パソコンなどで紐付け処理をすることが考えられるが、画像データとセンサの信号データが同時刻で対応させることが困難である場合がある。これを通常の画像内にセンサ信号を監視カメラ内で埋め込むことで解決することができる。ここで、画像データとセンサの信号データとの時刻同期には、同期信号生成部２４（たとえば、トリガ信号発生器、水晶発振器）を設け、生成される同期信号を用いてカメラ画像取得部６とセンサ信号取得部１０を動作させることで時間差の少なくした時刻を対応させることができる。 In such a case, conventionally, it is conceivable to collect sensor signal data using a data collection system separately provided from the camera device and link the data with a personal computer, but the image data and sensor signal data are the same. It may be difficult to correspond by time. This can be solved by embedding a sensor signal in a normal image in the surveillance camera. Here, for the time synchronization between the image data and the signal data of the sensor, a synchronization signal generation unit 24 (for example, a trigger signal generator, a crystal oscillator) is provided, and the camera image acquisition unit 6 is used with the generated synchronization signal. By operating the sensor signal acquisition unit 10, it is possible to correspond to a time with a small time difference.
　次に、図３～図５を用いて、画像内にセンサ信号を埋め込む原理を説明する。 Next, the principle of embedding a sensor signal in an image will be described with reference to FIGS.
　図３は、カメラ画像取得部６で取り扱われる画像データについて説明する図である。画像データは、図示するように、画素又はピクセルと呼ばれる構成要素に数値を割り当てて輝度を表現している。たとえば、８ビットの画像の場合、図３中の白が０で、黒が２５５の値をもつ。 FIG. 3 is a diagram for explaining the image data handled by the camera image acquisition unit 6. As illustrated, the image data expresses luminance by assigning numerical values to components called pixels or pixels. For example, in the case of an 8-bit image, white in FIG. 3 has a value of 0 and black has a value of 255.
　実際の監視カメラ３の画像は、被写体２の移動などに伴い、画素値の分布が変更される。たとえば、図３（a）から図３（ｂ）の変化は、中央の四角物体４１が右方向に移動した例である。このとき、画像の中で、ほとんど変化していない領域が存在する。固定した監視カメラ３による監視の場合、この領域がほとんど変わらない。そこで、このような領域にセンサ５のデータを埋め込み、ネットワークの構成やデータの構成の変更なしに、センサの追加や変更に対応できる監視カメラ３を提供するものである。 In the actual image of the surveillance camera 3, the distribution of pixel values is changed as the subject 2 moves. For example, the change from FIG. 3A to FIG. 3B is an example in which the central square object 41 has moved to the right. At this time, there is an area in the image that hardly changes. In the case of monitoring by a fixed monitoring camera 3, this area hardly changes. Therefore, the monitoring camera 3 is provided which can embed data of the sensor 5 in such an area and can cope with the addition or change of the sensor without changing the network configuration or the data configuration.
　図４は、センサの信号データを画像の画素値に変換する原理を説明する図である。センサ５の信号は、図４（a）のようにアナログで与えられる。このアナログ値は、アナログ－デジタル変換回路（ＡＤＣ１２）でデジタル化される。図４では、７階調でデジタル化した例である。これに対して、カメラ画像のビット数が８であれば、センサの信号データの数値に対応する画素値に変換することができる。図４（ｂ）は、信号値画素値変換部１１でセンサ５の信号データを画素値に変換した結果である。 FIG. 4 is a diagram for explaining the principle of converting sensor signal data into pixel values of an image. The signal of the sensor 5 is given in analog as shown in FIG. This analog value is digitized by an analog-digital conversion circuit (ADC 12). FIG. 4 shows an example of digitization with seven gradations. On the other hand, if the bit number of the camera image is 8, it can be converted to a pixel value corresponding to the numerical value of the sensor signal data. FIG. 4B shows the result of converting the signal data of the sensor 5 into pixel values by the signal value pixel value converter 11.
　図５は、データ合成部１４による信号データ組み込み画像データを生成する例を説明した図である。図３で説明したように、監視カメラの場合、画像データが変化しない領域が多い。この領域のうち、合成領域決定部１５によりセンサ５の信号データ数を用いて、合成領域を決定し、この領域に埋め込む信号データを取得したカメラ画像データを置換部１６で合成する。このようにして作成されたデータが図５である。このデータを伝送装置１９を通じて監視用ホストコンピュータ２０の表示部２３に表示させる。なお、監視用ホストコンピュータ２０の解析部２２では伝送装置より伝送された信号データ組み込み画像データに対し、過去に伝送された信号データ組み込み画像データとの差異を算出し、表示部２３で、差異のある画像データの領域と、センサの信号データの偏差とを表示し、過去の状態との偏差を監視するようにし複数のデータを図２の表示部２３に表示させるようにしてもよい。 FIG. 5 is a diagram illustrating an example in which image data embedded image data is generated by the data synthesis unit 14. As described with reference to FIG. 3, in the case of a surveillance camera, there are many areas in which image data does not change. Among these areas, the synthesis area determination unit 15 determines the synthesis area using the number of signal data of the sensor 5, and the replacement unit 16 synthesizes the camera image data obtained from the signal data to be embedded in this area. The data created in this way is shown in FIG. This data is displayed on the display unit 23 of the monitoring host computer 20 through the transmission device 19. The analysis unit 22 of the monitoring host computer 20 calculates the difference between the signal data embedded image data transmitted from the transmission device and the signal data embedded image data transmitted in the past, and the display unit 23 displays the difference. An area of certain image data and a deviation of signal data of the sensor may be displayed, and a deviation from a past state may be monitored to display a plurality of data on the display unit 23 in FIG.
　このような構成により、ネットワーク構成やデータ構成を変更することなく、センサ５の信号と監視カメラ３の画像を紐付けて監視するシステムの提供が可能となる。 Such a configuration makes it possible to provide a system that monitors the signal of the sensor 5 and the image of the monitoring camera 3 without changing the network configuration or the data configuration.
　実施例２を図６～図７を参照しつつ説明する。実施例２は、センサの種類や個数が変更になった場合のものである。 Example 2 will be described with reference to FIGS. In the second embodiment, the type and number of sensors are changed.
　図６は、実施例２に係る監視カメラシステムの全体構成を模式的に示す機能ブロック図である。図１と異なる点は、センサ信号取得部１０の構成において、センサを切り替えるマルチプレクサ回路（ＭＵＸ５１）、センサ出力の範囲を自動的に検知し、すべてのセンサ５の出力を同程度の出力範囲に増幅・減衰させる自動ゲイン調整回路（ＡＧＣ５２）を有する点である。複数のセンサを扱う場合、感度が異なるため。このとき、センサの信号をデジタル化するＡＧＣの入力範囲は、一定である。この入力範囲に対して、極端に出力範囲小さいセンサ５では、センサ５の信号の変動を捕らえられない。そのため、ゲインを自動調整した上で、ＡＤＣ１２でデジタル化する。また、正しい出力範囲を保存するため、ＡＧＣのゲイン出力を同じくデジタル化し、センサ信号とともに、合成画像として取り使う流れである。これにより複数のセンサ、異なるセンサが追加されても、画像データの画素数を上限にセンサ信号を取り扱うことが可能となる。 FIG. 6 is a functional block diagram schematically illustrating the overall configuration of the surveillance camera system according to the second embodiment. The difference from FIG. 1 is that in the configuration of the sensor signal acquisition unit 10, a multiplexer circuit (MUX 51) that switches the sensors, automatically detects the sensor output range, and amplifies the outputs of all the sensors 5 to the same output range. -It is a point which has the automatic gain adjustment circuit (AGC52) to attenuate. The sensitivity is different when handling multiple sensors. At this time, the input range of the AGC for digitizing the sensor signal is constant. In the sensor 5 whose output range is extremely small with respect to this input range, fluctuations in the signal of the sensor 5 cannot be captured. Therefore, the ADC 12 digitizes the gain after automatically adjusting the gain. Also, in order to preserve the correct output range, the AGC gain output is also digitized and used as a composite image together with the sensor signal. As a result, even if a plurality of sensors or different sensors are added, the sensor signal can be handled with the upper limit of the number of pixels of the image data.
　図７は、実施例２に係る監視カメラシステムの利用形態を示す図である。実施例１と同様に、監視カメラ３は、ネットワーク（伝送装置１９）に接続されており、監視用ホストコンピュータ２０で、データの閲覧、監視カメラ３の制御を行う。 FIG. 7 is a diagram illustrating a usage form of the surveillance camera system according to the second embodiment. As in the first embodiment, the monitoring camera 3 is connected to a network (transmission device 19), and the monitoring host computer 20 browses data and controls the monitoring camera 3.
　監視カメラ３には、センサを接続するコネクタポート４が備わっており、複数のセンサ５を接続することができる。ここで、接続するセンサ５は、アナログ出力をするセンサであり、たとえば、磁気センサ、温度センサ、湿度センサ、振動センサ、加速度センサ、ひずみセンサ、近接センサ、音声センサ、超音波センサ、電流センサ、電圧センサ、光センサ、放射線センサなどがある。 The monitoring camera 3 is provided with a connector port 4 for connecting sensors, and a plurality of sensors 5 can be connected. Here, the sensor 5 to be connected is a sensor that performs analog output. For example, a magnetic sensor, a temperature sensor, a humidity sensor, a vibration sensor, an acceleration sensor, a strain sensor, a proximity sensor, a voice sensor, an ultrasonic sensor, a current sensor, There are voltage sensors, optical sensors, radiation sensors, and the like.
　例として、図７で図示しているように、プロペラ３０を回転させるモータ３１での利用形態を説明する。モータ３１はプロペラ３０を回転させており、プロペラ３０に欠陥などが生じると正常に起きない振動を呈することがある。これは実施例１と同様に振動センサを用いて、カメラの動画と振動センサの信号を紐付けて監視することが可能である。さらに、応答が速く、モータの利用状況も把握できる駆動電流や電圧を紐付けて監視することによって、より精密な監視を実施することができる。 As an example, a usage form in a motor 31 that rotates a propeller 30 as illustrated in FIG. 7 will be described. The motor 31 rotates the propeller 30, and when the propeller 30 is defective or the like, vibration that does not occur normally may occur. In the same manner as in the first embodiment, it is possible to monitor the moving image of the camera and the signal of the vibration sensor by using the vibration sensor. Furthermore, more precise monitoring can be performed by linking and monitoring drive currents and voltages that are fast in response and that can grasp the usage status of the motor.
　このような構成により、センサの追加、変更といった拡張性に対応できる監視カメラを提供することができ、ネットワーク構成やデータ構成を変更することなくより精密な監視を実施することができる。 With such a configuration, it is possible to provide a monitoring camera that can cope with expandability such as addition and change of sensors, and it is possible to perform more precise monitoring without changing the network configuration or data configuration.
　なお、本発明は上記した実施例に限定されるものではなく、様々な変形例が含まれる。例えば、上記した実施例は本発明を分かりやすく説明するために詳細に説明したものであり、必ずしも説明した全ての構成を備えるものに限定されるものではない。また、ある実施例の構成の一部を他の実施例の構成に置き換えることが可能であり、また、ある実施例の構成に他の実施例の構成を加えることも可能である。また、各実施例の構成の一部について、他の実施例の構成の追加・削除・置換をすることが可能である。 In addition, this invention is not limited to the above-mentioned Example, Various modifications are included. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described. Further, a part of the configuration of one embodiment can be replaced with the configuration of another embodiment, and the configuration of another embodiment can be added to the configuration of one embodiment. Further, it is possible to add, delete, and replace the configurations of other embodiments with respect to a part of the configurations of the embodiments.
