Description

  The present invention relates to a monitoring apparatus, a monitoring method, and a program for monitoring an adverse effect that occurs on a monitoring target due to external factors.

  For example, a device operated by an unspecified number of people such as an ATM (Automatic Teller Machine) may be installed in an environment where no resident maintenance personnel are present. ATMs are installed not only in bank buildings where employees are present, but also in office buildings and commercial buildings, in convenience stores, and in corners of underground passages, where there are no employees. Similarly, as an example of an apparatus arranged in an environment where maintenance personnel are not resident in the vicinity, there is an automatic contract machine installed in an unmanned store by a financial institution.

  This type of device is often operated while monitoring from a remote location. As a monitoring method, when a functional failure occurs in a device, a warning message is sent from the device to a remote monitoring terminal.

  Specifically, for example, when the occurrence of a failure is detected, an e-mail describing a message related to the failure is sent to a predetermined address via the data communication network.

  As another monitoring method, mainly from the viewpoint of crime prevention, there is a method of generating image data such as a still image or a moving image obtained by photographing the device and its surroundings and distributing it through a data communication network. In this method, since humans are the main monitoring targets, things that are extremely different in size from humans, such as dust, are not monitored.

  As another monitoring method, there is a method in which a sensor that detects dirt attached to a specific minimum point is provided, and the detection result is notified to a monitoring terminal via a data communication network.

  These monitoring methods mainly target troubles that occur in the apparatus and its surroundings and that cannot be used unless the problem is dealt with. Normally, such a monitoring method does not notify the monitoring terminal even if dust is accumulated on the surface of the apparatus. For this reason, for example, there is no problem with the ATM function, and it is operating normally, but there may be a situation where dust is accumulated on the ATM touch panel surface. As a result, ATM users may give up using the ATM by avoiding touching a dirty touch panel. Moreover, since the supervisor who monitors an apparatus with a monitoring terminal does not notice the stain | pollution | contamination of a touch panel, it cannot take countermeasures, such as instructing maintenance personnel to clean the touch panel according to the amount of dust.

  As a technique related to the present invention, Patent Document 1 describes an image reading apparatus that can accurately detect image defects caused by foreign matters such as dust and dust attached to a film, scratches on the film, and the like without erroneous detection. Has been. In particular, in the paragraph 0024, “image defects (hereinafter referred to as image defects caused by foreign matter such as dust and dust attached to the film F, scratches entering the film F, etc. using image data of IR image (non-visible image)”). , “Defect scratch”.

  As another technique related to the present invention, Patent Document 2 describes a defect inspection apparatus that can detect a defect of an inspection object having a color pattern with high accuracy. In particular, paragraph 0017 describes that the inspection target surface of the sheet-like inspection object 100 is irradiated with light having a wavelength of 780 nm or more. In the 0019th paragraph, it is described that an image of an inspection object in which only shadow information due to physical unevenness is reflected is captured by the reflected light.

  Patent Documents 1 and 2 describe detecting where a defect or the like exists in an inspection object. However, both Patent Documents 1 and 2 are intended to inspect defects of the inspection object itself, and do not describe any necessity for inspecting other than defects. That is, Patent Documents 1 and 2 do not consider continuous use or detection of a change in an inspection object due to an external factor. For example, when an inspection object is used for a long period of time, dirt or dust inevitably adheres to the inspection object, resulting in an adverse effect on the appearance of the inspection object. It may be difficult to use.

  The present invention has been made in view of such circumstances, and the problem to be solved by the present invention is to monitor an object to be inspected, that is, monitoring that can reduce adverse effects caused by dust, dust, and dirt adhering to or falling on the object to be monitored. An apparatus, a monitoring method, and a program therefor are provided.

  In order to solve the above-described problems, the present invention has, as one aspect thereof, an input device that monitors dirt in a monitoring target region of a monitoring target object and generates a monitoring result indicating the degree of dirt, and receives and monitors the monitoring result. A monitoring system is provided that includes a monitoring device that detects the state of a target region and generates an alarm when the state of the monitoring target region deteriorates.

  In another aspect of the present invention, the light source device is used to irradiate light onto a monitoring target region including a region where dirt is to be monitored among the monitoring target, using a camera. Step 2 for photographing the monitoring target area irradiated with light and generating image data, and Step 3 for transmitting a message generated based on the image data to a predetermined monitoring terminal via the data communication network. A remote monitoring method characterized by monitoring the degree of contamination of the monitoring target area and generating an alarm according to the degree of contamination.

  Moreover, this invention uses the procedure 1 which irradiates light with respect to the monitoring object area | region including the area | region which monitors a dirt among monitoring objects using a light source device as another one aspect, using a camera. Step 2 for photographing the monitoring target area irradiated with light and generating image data, and Step 3 for transmitting a message generated based on the image data to a predetermined monitoring terminal via the data communication network Is provided to monitor the degree of contamination of the monitoring target area and generate an alarm according to the degree of contamination.

  According to the present invention, the degree of contamination of the monitoring target area of the monitoring target in a remote place is digitized as an index value, and a message related to the numerical value is transmitted to the monitoring terminal. It can be grasped as a numerical value.

FIG.

  A remote monitoring system 1 according to an embodiment of the present invention will be described. Referring to FIG. 1, the remote monitoring system 1 includes a light source 2, a camera 3, an image analysis unit 4, a communication unit 5, a monitoring control unit 6, a data communication network 7, and a monitoring terminal 8. Among these, a subsystem including the light source 2, the camera 3, the image analysis unit 4, the communication unit 5, and the monitoring control unit 6 is referred to as a monitoring device 9. A subsystem including the light source 2, the camera 3, and the communication unit 5 is referred to as an input device. The remote monitoring system 1 transmits a warning message to the monitoring terminal 8 when dust in the monitoring target area 11 is detected in the monitoring target 10 that is the monitoring target.

  The light source 2 is a device for irradiating the entire monitoring target region 11 with light. The light source 2 preferably emits light including infrared rays, and particularly preferably emits light including near infrared rays. Specifically, it is conceivable to use, as the light source 2, an LED (Light Emitting Diode) that emits infrared light (InfraRed) including near infrared light. Hereinafter, the infrared LED may be referred to as an IR LED.

  The camera 3 is a camera configured to be able to photograph the entire monitoring target area 11 and outputs image data of the monitoring target area 11. The file format of image data is not particularly limited. When the light source 2 emits infrared rays or near infrared rays, it is preferable that the imaging device of the camera 3 has sensitivity in the infrared region or near infrared region. The imaging device of the camera 3 may be, for example, a CCD (Charge Coupled Device), a CMOS (Complementary MOS), an InGaAs (Indium Gallium Arsenide), an InSb (Indium Antimonide), or the like. The used infrared detection element may be used. Hereinafter, the infrared camera may be referred to as an IR visible camera.

  The light source 2 emits infrared rays, and particularly preferably includes near infrared rays. At this time, when the light source 2 irradiates infrared rays or near infrared rays, the camera 3 is preferably an infrared camera that includes an infrared sensor that converts light including an infrared region into an electrical signal and is capable of photographing infrared rays. An infrared camera capable of photographing infrared rays is preferable.

  Considering this, hereinafter, only the case where an IR LED and an IR visible camera are used as the light source 2 and the camera 3, respectively, will be described. When light is applied to minute dust such as dust, scattered light is generated in the minute dust. The present invention uses this phenomenon to calculate the amount of minute dust. That is, the amount of minute dust is calculated by performing image analysis processing on the image of the monitoring target region and identifying a portion emitting scattered light. Micro dust emits scattered light particularly strongly when irradiated with infrared rays or near infrared rays. For this reason, the light source 2 preferably emits infrared rays, particularly near infrared rays, and the camera 3 preferably has sensitivity in the infrared region, particularly near infrared region.

  The image analysis unit 4 is a processing device that performs image analysis processing on image data. More specifically, the image analysis unit 4 performs image analysis processing on the image data of the monitoring target area 11 generated by the camera 3 while illuminating with the light source 2, and an index value corresponding to the amount of dust in the monitoring target area 11. Is compared with a threshold value of a predetermined index value, and the comparison result is output to the monitoring control unit 6.

  When an article having fine dust such as dust attached to its surface is irradiated with light and photographed with a camera capable of photographing the light, an image including scattered light due to the fine dust can be obtained. As shown in FIG. 2, the desktop computer is set as the monitoring object 10, the screen of the liquid crystal display device is set as the monitoring target area 11, illuminated by the light source 2 (not shown), and photographed by the camera 3. The power supply or output to the screen of the liquid crystal display device is off. The screen of the liquid crystal display device does not emit light and is black, and when it is illuminated with light, scattered light is generated by minute dust on the screen, and an image as shown in FIG. 3 is obtained. In this figure, white dots on the screen are minute dust or dust. The image analysis unit 4 calculates an index value based on a white portion in the image.

  Returning to FIG. 1, the communication unit 5 is a data communication interface device for communicating with the monitoring terminal 8 via the data communication network 7 in accordance with the output of the image analysis unit 4. Send.

  When the connection to the data communication network 7 is performed by wire, the communication unit 5 is a wired data communication interface device, and for example, the data communication network 7 via a LAN (Local Area Network) cable, an optical fiber cable, a coaxial cable, or the like. Connected. On the other hand, when the connection with the data communication network 7 is performed wirelessly, the communication unit 5 is a wireless data communication interface device, for example, a wireless LAN such as IEEE802.11 and a mobile phone communication such as LTE (Long Term Evolution). Wireless data communication is performed based on a standard, a short-range wireless communication standard such as Bluetooth (registered trademark), and the like, and the data communication network 7 is connected.

  The warning message is a message for notifying that a certain amount of dust has accumulated in the monitoring target area 11. As a message transmission form, for example, an e-mail transmitted to a predetermined e-mail address can be considered. In this case, the monitoring terminal 8 is installed with e-mail client software set to receive the predetermined e-mail address. Other transmission forms include instant message, SMS (Short Message Service), and the like. Client software corresponding to the message transmission mode is installed in the monitoring terminal 8. The message transmission form is preferably push distribution, but may be pull distribution.

  The monitoring control unit 6 is a processor that controls operations of the light source 2, the camera 3, the image analysis unit 4, and the communication unit 5, and monitors the monitoring target 10. That is, the dust index value of the monitoring target area 11 is calculated, and when the index value exceeds a predetermined threshold, a warning message is sent to the monitoring terminal 8 via the data communication network 7.

  The data communication network 7 is a data communication network such as the Internet. The data communication network 7 may be formed by interconnecting a plurality of computer networks each having a different network address. The data communication network 7 may be a wired network, a wireless network, or a wired network and a wireless network interconnected.

  The monitoring terminal 8 is a terminal device connected to the data communication network 7. The monitoring terminal 8 only needs to be able to perform data communication with the communication unit 5 via the data communication network 7. For example, various information processing such as a desktop computer, a laptop computer, and a workstation connected to the Internet. It may be a terminal or a wireless data communication terminal such as a mobile phone device or a smartphone.

  The monitoring object 10 is an article including a monitoring object area 11 that is an area to be monitored by the remote monitoring system 1. For example, the monitoring object 10 is a device that is used by an unspecified number, and the monitoring target region 11 is a touch display included in the device. Examples of this type of device include ATMs (Automatic Teller Machines), automatic contract machines, and the like.

  The monitoring target area 11 is not necessarily limited to a part of the monitoring target object 10 and may be the entire monitoring target object 10. When the entire monitoring target 10 is used as the monitoring target region 11, the light source 2 is arranged so that the entire monitoring target 10 can be irradiated with light, and the camera 3 can capture the entire monitoring target 10. Be placed.

  Next, the operation of the remote monitoring system 1 will be described.

  When a predetermined operating condition is satisfied, the monitoring controller 6 starts the monitoring process shown in FIG. As an operation condition, for example, one that is executed periodically such as once at midnight every day can be considered. As another operating condition, the monitoring device 9 is further provided with a light / dark sensor (not shown), and the brightness of a room or the like in which the monitoring object 10 is installed is measured by the light / dark sensor, and the room becomes dark. It can be executed. In addition, as another operating condition, a light / dark sensor is provided in the same manner as the above-described operating condition, for example, a first time when 10 minutes or more have passed in a predetermined time zone of the day and the room is dark. It is possible to execute it on

  When the operation condition is satisfied, first, the monitoring control unit 6 switches on the light source 2 to illuminate the monitoring target region 11 (step S1). Next, the monitoring control unit 6 captures the monitoring target area 11 with the camera 3 and generates image data (step S2). Next, the monitoring control unit 6 causes the image analysis unit 4 to perform an image analysis process on the generated image data to generate an index value (step S3). In the image analysis processing, for example, the area of a region (white region) emitting scattered light indicating dust in the monitoring target region 11 is obtained from image data captured as shown in FIG. 3, and the obtained area is used as an index value. It is possible to use as. Next, the image analysis unit 4 compares the obtained index value with a predetermined threshold value (steps S4 and S5). As the threshold value, for example, it is conceivable to use an index value when a predetermined ratio (for example, 30%) of the area of the monitoring target region 11 is covered with dirt. The threshold value is stored in advance in a storage device provided in the image analysis unit 4 or the monitoring control unit 6. If the index value is greater than or equal to the threshold value, the monitoring control unit 6 sends a warning message from the communication unit 5 to the monitoring terminal 8 via the data communication network 7 (step S6). If the index value is less than the threshold value, the monitoring controller 6 does nothing and ends the process.

  According to such a remote monitoring system 1, when a certain amount or more of dust accumulates in the monitoring target area 11, the monitoring person can notice that the warning message reaches the monitoring terminal 8. For this reason, the monitoring person can go to the monitoring object 10 and clean the monitoring object area 11.

  In the remote monitoring system 1, the warning message is sent according to the comparison result between the index value and the threshold value, but the index value generated in step S3 is sent as it is to the monitoring terminal 8 without being compared with the threshold value. Also good. In this case, the comparison between the index value and the threshold value performed in steps S4 and S5 is omitted.

  Further, the image data generated by the camera 3 may be transmitted to the monitoring terminal 8 as it is together with the index value or without generating the index value. When no index value is generated, steps S3-S5 are omitted. The image analysis unit 4 is not necessary.

  Further, since the remote monitoring system 1 sends a message regarding the amount of accumulated dust in the monitoring target area 11 to the monitoring terminal 8, if the dust needs to be monitored, the monitoring target 10 may be an ATM or automatic contract. It does not have to be a device like a machine. The monitoring target object 10 or the monitoring target area 11 may be a part of a building such as an exhibit such as a work of art or a craft, a window glass, or a door.

  In the remote monitoring system 1 described above, the monitoring terminal 8 and the monitoring device 9 have a one-to-one relationship, but the present invention is not limited to this. As shown in FIG. 5, N monitoring devices 9-1, 9-2,..., 9 -N may be monitored using a single monitoring terminal 8.

  When the monitoring target 10 is a device such as an ATM or an automatic contract machine, the device to be monitored and the monitoring device 9 may be linked. As shown in FIG. 6, the monitoring target device 20 corresponding to the monitoring target 10 includes a touch panel 21 and a main body control unit 22 in addition to the configuration of the monitoring device 9. The monitoring target device 20 includes a plurality of IR LED light sources 2.

  By providing a plurality of IR LED light sources 2, it becomes easy to illuminate the entire area of the touch panel 21, which is the monitoring target area, with infrared rays. The IR LED light source 2 is an LED (Light Emitting Diode) that emits infrared rays (InfraRed) including near infrared rays.

  The infrared camera 3 is a camera having sensitivity to near infrared rays. Although only one infrared camera 3 is shown in FIG. 6, a plurality of infrared cameras 3 may be installed and the entire area of the touch panel 11 may be covered by the plurality of infrared cameras 3.

  The touch panel 21 corresponds to the monitoring target area 11. The touch panel 21 is an input / output device that serves as both a display device and an input device.

  The main body control unit 22 is a processor that controls the original operation of the monitoring target device 20. When the monitoring target device 20 is an ATM, the main body control unit 22 controls the original operation of the monitoring target device 20, for example, processing and operations related to cash acceptance and payment when it is an ATM. The main body control unit 22 notifies the operation state of the monitoring target device 20 to the monitoring control unit 6. The operating state notified here includes, for example, whether or not the monitoring target device 20 is powered on and whether or not the original operation is being executed.

  The monitoring target device 20 operates in the same manner as the monitoring device 9 described above. However, it differs in that the operating condition that triggers the operation of FIG. 4 is determined based on the operating state notified from the main body control unit 9. For example, according to the operation state notified from the main body control unit 22, when the power of the monitoring target device 20 is off, the operation of FIG. 4 is executed once a day.

  When dirt such as dust adheres to the touch panel 21, there is a problem that the visibility of the screen is lowered as a display device. In addition, as an input device, there is a problem that an operator avoids contact and as a result, the number of users decreases. In the monitoring target device 20, the amount of dirt adhered to the touch panel 21 is represented by an index value, and a message is transmitted to the monitoring terminal according to the determination result based on the index value. By receiving the message, the user of the monitoring terminal knows that the monitoring target device 200 touch panel 21 in the remote place is dirty to some extent, and can trigger the cleaning of the touch panel 21.

  In the remote monitoring system 1 described above, the image analysis unit 4 compares the index value with the threshold value to determine whether or not the monitoring target area is dirty. The present invention is not limited to this, and the monitor of the monitoring terminal may determine whether there is dirt. In this case, in the flowchart of FIG. 4, after the image data of the monitoring target area 11 is generated in step S2, steps S3-S5 are omitted, and instead of sending a warning message in step S6, the image generated in step S2 A message including data is transmitted to the monitoring terminal 8. The user of the monitoring terminal, that is, the monitoring person visually checks the image to determine the presence or absence of dirt. If it is determined that it is dirty, the monitor may go to clean the monitoring target area 11 by himself / herself, or the monitoring terminal 8 may be used for the mail address, instant message address, SMS address, etc. assigned to the cleaner in advance. A message prompting cleaning of the monitoring target area 11 may be transmitted. In this case, it is not the monitoring device 9 but the monitoring person who uses the monitoring terminal 8 that determines whether or not the monitoring target area 11 needs to be cleaned.

  In addition, the index data may be transmitted instead of transmitting the image data generated in step S2 to the monitoring terminal 8 in this way. In this case, only step S5 of FIG. 4 is omitted, and a message including image data and an index value or a message including an index value is transmitted to the monitoring terminal 8 instead of the warning message in step S6.
