Description

Technical Field

[0001] The present invention relates to an image information acquisition type fastening means and a monitoring system.

Background Art

[0002] Currently, various members are used in various scenes, including buildings such as buildings, bridges, towers, dams, etc. (hereinafter referred to as buildings) that form spaces such as buildings, houses, halls, etc., various means of transportation including vehicles such as automobiles, bicycles, railways, etc., machinery and equipment, electrical equipment, power generation equipment, chemical plants, etc. (hereinafter referred to as structures). Also, various materials such as iron, resin, rubber, stone, concrete, wood, ceramic, glass, etc. are used as the materials.

[0003] For example, just taking buildings, there are various things related to social infrastructure such as houses, apartment buildings, school buildings, station buildings, airport terminals, hospitals, town halls, bridges, tunnels, etc. These buildings are maintained in their shapes by various structural materials such as columns, beams, floors, ceilings, bolts, nuts, reinforced concrete, etc. Also, not limited to structural materials, various members and facilities such as window glass and doors are used and are configured in various shapes and structures by various materials.

[0004] Structural materials are assumed to be used over a long period of time, but due to thermal expansion and contraction due to temperature changes, aging over time, and external forces due to impacts such as earthquakes, aging is inevitable. If aging is left unattended, there is also a risk of disasters related to human life.

[0005] In addition, disasters such as typhoons, tornadoes, and earthquakes, which are expected to be larger in the future, may apply excessive stress and load even to window glass, resulting in cracks or chipping. If these are left unattended, it may lead to cracks in the window glass and the risk of injury.

[0006] Therefore, in the future, it is important to be able to quantitatively and extensively monitor various members such as building materials and perform maintenance to prevent accidents and disasters and achieve disaster reduction and prevention (national resilience). Conventionally, a technique has been proposed in which defects on the surface of concrete are photographed by a camera such as a high-definition camera, and a defect inspection is performed while looking at the image (for example, Patent Document 1).

[0007] In addition, a technique has been proposed in which a drone equipped with a camera is flown by remote control to photograph structures such as dams, buildings, and viaducts, and the photographed images are used to inspect the structures (for example, Patent Document 2).

Summary of the Invention

Problems to be Solved by the Invention

[0009] However, even taking buildings as an example, there are a huge number of them at present, and it is practically impossible to prioritize the building materials that need to be maintained or to determine which structural materials in a single building should be intensively maintained.

[0010] In addition, even when performing visual inspections or inspections using camera images, it is ultimately necessary to go to the site, but continuously performing regular inspections of a huge number of buildings, etc. is very difficult from the viewpoints of securing necessary personnel, moving to the site, the time required for inspections, or the associated risks.

[0011] In addition, according to shooting using a drone, it becomes possible to inspect locations that are difficult for workers to approach easily. However, it may not be able to fly due to strong rain or wind, or its attitude may not be maintained even if it is made to fly. That is, the inspection using a drone may not be available at all depending on the weather, and the inspection can only be performed while the drone is flying.

Embodiment for Carrying out the Invention

[0036] Hereinafter, an embodiment of a monitoring system using the image information acquisition type fastening member of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the monitoring system 1 of the present embodiment. The monitoring system 1 includes a plurality of image information acquisition type fastening members 10 and a monitoring device 100, and the image information acquisition type fastening member 10 and the monitoring device 100 are communicably connected wirelessly or by wire.

[0037] FIG. 2 is a diagram showing the appearance of the image information acquisition type fastening member 10 of the present embodiment. The image information acquisition type fastening member 10 includes a fastening body 12, an imaging unit 20 capable of imaging moving images and / or still images, and the like. The fastening body 12 has a so-called bolt-like shape. For example, the fastening body 12 is composed of a head 14 having a hexagonal outer shape and a shaft portion 16 (screw portion) in which male screw spiral grooves are formed on at least a part of the outer peripheral surface.

[0038] The imaging unit 20 is a digital camera capable of imaging the monitoring target area attached to the fastening body 12. Here, it is an omnidirectional camera, and an omnidirectional (360°) panoramic image is acquired. Also, the imaging unit 20 has a size that does not protrude radially outside the head 14. That is, the imaging unit 20 has a shape that fits within the contour of the outer peripheral surface of the head 14 in the axial view of the fastening body 12. Also, FIG. 3 is a block diagram showing the imaging unit 20. The imaging unit 20 has a control unit 22 that comprehensively controls the operations of each part. Connected to the control unit 22 are an imaging unit 24, an image processing unit 25, a storage unit 26, an analysis unit 28, a transmission / reception unit 30, a position information acquisition unit 32, an azimuth sensor 34, a power supply unit 36, etc.

[0039] The imaging unit 24 includes an optical system including a fish-eye lens or an ultra-wide-angle lens, a zoom lens, and a focus lens, and an imaging element such as a CCD or a CMOS that generates an imaging signal based on the subject light incident on the imaging surface. Also, the imaging unit 24 is not limited to one, and there may be a plurality of them.

[0040] For example, when the viewing angle by the optical system is 180° or more, as shown in FIG. 4(a), the imaging unit 20 is composed of two imaging units 24a and 24b. That is, the imaging unit 20 is composed of an imaging unit 24a including an optical system 40a and an imaging element 42a, and an imaging unit 24b including an optical system 40b and an imaging element 42b. Also, the imaging units 24a and 24b are arranged such that the optical axes of the respective optical systems 40a and 40b are aligned on the same straight line. Thereby, since the imaging units 40a and 40b image the back side that is outside the shooting range of one with the other, it becomes possible to acquire an omnidirectional panoramic image.

[0041] In addition, if there are three or more imaging units 24, the blind spots in the shooting range can be further eliminated. For example, in a plane parallel to the plane on which the camera unit 20 is fixed, the imaging unit 24 may be configured by arranging four imaging units in different directions at intervals of 90°. Specifically, as shown in FIG. 4(b), the imaging element 42a is arranged with the direction of θ = 0°, the imaging element 42b is arranged with the direction of θ = 180°, the imaging element 42c is arranged with the direction of θ = 90°, and the imaging element 42d is arranged with the direction of θ = 270°. In this way, what exists between the imaging elements 42a and 42b and outside both imaging ranges can be imaged by the imaging elements 42c and 42d, and what exists between the imaging elements 42c and 42d and outside both imaging ranges can be imaged by the imaging elements 42a and 42b, so that a panoramic image without blind spots can be obtained.

[0042] In addition, the imaging unit 20 may further include a rotation mechanism for rotating the optical system and the imaging element, and an operation circuit capable of remotely operating the rotation mechanism. In this way, even if each viewing angle by the optical systems 40a and 40b and the imaging elements 42a and 42b is less than 180°, substantially omnidirectional imaging can be achieved by operating the rotation mechanism according to the instruction received via the transmission / reception unit 30.

[0043] The image processing unit 25 creates panoramic image data by performing various image processes on the imaging signals generated by the imaging elements of the imaging unit 24. Specifically, panoramic image data is created by performing a synthesis process or the like for connecting the image data based on the imaging signals generated from a plurality of imaging elements. Of course, the image processing by the image processing unit 25 is not limited to this, and includes known image processes such as A / D conversion processing, pixel interpolation processing, resizing processing, and color correction processing.

[0044] The storage unit 26 stores the unique ID of the image information acquisition type fastening member 10, and also stores the processing results of each unit, etc. Note that the storage unit 26 may store the image data based on the imaging signals generated by each imaging unit 24 that serves as the basis of the panoramic image data.

[0045] The analysis unit 28 performs detection of detection targets (shown in the panoramic image) existing in the monitoring target area through image analysis. Here, the detection targets include, for example, loosening, corrosion (rust, etc.), damage (peeling, flaking, chipping, cracking, scratches, etc. of paint, etc.), dirt, deformation (including bending, warping, breaking, stretching, shrinking, swelling, contraction, etc.), displacement (settling, movement, inclination, etc.), discoloration, alteration, stain, dropping off, play, falling out, clogging (of earth and sand, etc.), adhesion of foreign matter, burning, charring, disappearance, etc. of fasteners such as bolts and nuts including itself (fastening body 12) shown in the panoramic image. Further, the foreign matter includes moisture including raindrops and snow, salt, bird droppings, sand, dust, pollen, etc., and includes those that can cause a burden or corrosion of the member.

[0046] For example, the detection method of the detection target may be to set a reference luminance for each subject and detect a location where the luminance has changed with respect to the reference luminance as the detection target. In the detection by the change in luminance, good image data cannot be obtained in a time zone when the sun has set and there is little visible light compared to a time zone such as a bright day. Similarly, good image data cannot be obtained in a location that is shaded and has little sunlight hitting it.

[0047] Therefore, an infrared light irradiation unit (not shown) may be provided around the imaging unit 20, on the top surface and / or the circumferential surface of the head 14, etc. When the amount of light is small, infrared light is irradiated and the state of irradiating infrared light is set as the reference luminance, and the detection target may be detected while irradiating infrared light. Further, instead of the infrared light irradiation unit, a light emitting element such as an LED may be disposed, and imaging may be performed by the imaging unit 20 while irradiating the imaging range with light from the light emitting element. Also, known appearance inspection using image recognition AI technology by machine learning may be applied to perform inspection, analysis, anomaly detection, etc. of the detection target.

[0048] Further, the analysis unit 28 may detect a detection target (loosening of the image information acquisition type fastening member 10 itself) by detecting the difference between an image captured at a certain time point and an image captured thereafter. Specifically, when loosening occurs in the fastening body 12, the imaging unit 20 rotates in the loosening direction together with the fastening body 12, and the optical axis of the optical system of the imaging unit 24 moves. Therefore, for example, by storing in advance in the storage unit 26 the captured image at the time of member fastening as a reference image, comparing the image captured by the imaging unit 20 with the reference image, and detecting the difference such as the positional deviation of the subject in the image, it is possible to detect the loosening that has occurred in the fastening body 12 and to calculate the loosening rotation angle. Of course, performing difference detection by comparing images at different time points is not limited to the purpose of detecting the loosening that has occurred in itself. For example, it may be performed to detect the loosening of other fastening bodies.

[0049] Further, the analysis unit 28 may detect a person or the like as a detection target and track the detection target when it moves. When the detection target is a person, the detection target may be detected using face detection or human body detection technology, and for example, the detection target detected by position prediction, template matching, or the like may be tracked.

[0050] The transmission / reception unit 30 transmits and receives data to / from the monitoring device 100 via an antenna (not shown). For example, in addition to transmitting panoramic image data, it receives various types of information. The position information acquisition unit 32 receives a signal from the outside such as a GPS satellite or a wireless LAN to acquire position information, or may register position information acquired in advance by some method. The azimuth sensor 34 includes a geomagnetic sensor or the like and detects the azimuth when the image information acquisition type fastening member 10 is used as a reference. The power supply unit 36 supplies the power necessary for the operation of each unit. Note that an external power source (not shown) or a battery (not shown) that supplies power can be connected to the power supply unit 36. Further, a power generation element that can generate power by receiving various forms of energy such as heat, light, vibration, pressure, and radio waves from the outside may be connected to supply the necessary power.

[0051] The monitoring device 100 is an information processing terminal capable of receiving panoramic image data and displaying a panoramic image, and includes a communication unit 110 that transmits and receives various data, a display unit 112 that displays a panoramic image of the received panoramic image data, and the like. The monitoring device 100 is, for example, a smartphone capable of displaying a panoramic image, a mobile phone (feature phone), a PDA (Personal Digital Assistant), a wearable terminal (head-mounted display, glasses-type device, etc.), a tablet terminal, a notebook PC, a desktop PC, and other various computers and monitors having an arithmetic circuit. Further, the monitoring device 100 may directly communicate with the image information acquisition type fastening member 10, or may transmit and receive data via a distribution server or the like.

[0052] Next, the application of the image information acquisition type fastening member 10 to a structure will be described. FIG. 5 is an enlarged view showing a building to which the image information acquisition type fastening member 10 of the present embodiment is applied. The image information acquisition type fastening member 10 can be applied, for example, as a screw fastening body that fastens fastening members constituting a building to each other. Further, the image information acquisition type fastening member 10 is disposed so that the imaging unit 20 is exposed when the members are fastened to each other.

[0053] Specifically, as shown in FIG. 5, at a plurality of joint portions connecting columns 52 made of rectangular tubular steel members extending in the vertical direction of the building 50, and joint portions connecting H-shaped steel members extending horizontally from the columns 52, so-called H-beams 54, an image information acquisition type fastening member 10 serving as a screw fastening member is fastened using a connection plate 56. This image information acquisition type fastening member 10 becomes a portion for joining structural members (frame members) of the building 50. Further, the imaging unit 20 is exposed outside the structural member so as to be able to image the surroundings.

[0054] It is preferable to select locations where the axial directions (fastening directions) of the plurality of image information acquisition type fastening members 10 are different from each other. In this way, panoramic images at different positions and orientations can be acquired, and it becomes possible to perform monitoring while grasping the surface state of the building 50 and the surrounding situation.

[0055] Next, a process of causing the monitoring device 100 to display the panoramic image captured by the image information acquisition type fastening member 10 will be described. The image information acquisition type fastening member 10 that fastens the structural members of the building 50 performs imaging by the imaging unit 20. That is, the control unit 22 causes the imaging unit 20 to perform imaging and acquires image data. The control unit 22 creates panoramic image data from the image data. Specifically, when the imaging unit 20 includes a plurality of imaging units 24, the control unit 22 synthesizes the image data from each imaging unit 24 by the image processing unit 25 to create panoramic image data.

[0056] The control unit 22 performs analysis processing on the panoramic image data by the analysis unit 28 to detect a detection target. In the analysis processing, detection locations are detected from changes in luminance as described above, or detection locations are detected by face detection, human body detection, etc., and appropriate detection methods are performed.

[0057] Also, the control unit 22 acquires the position information by the position information acquisition unit 32 and the azimuth information that is the detection result by the azimuth sensor 34, and associates the panoramic image data, the detection target, the position information, and the azimuth information with each other and stores them in the storage unit 26. The control unit 22 transmits the monitoring image information combining the unique ID, the panoramic image data, the detection target, the position information, and the azimuth information stored in the storage unit 26 to the monitoring device 100 by the transmission / reception unit 30.

[0058] The monitoring device 100 displays a monitoring image on the display unit 112 based on the received monitoring image information. The monitoring image shows, in addition to the panoramic image, the shooting position, azimuth, detection target, etc. based on the position information. In the monitoring image including the detection target, for example, a frame image surrounding the detection target is superimposed and displayed in the panoramic image. Specifically, for one detection target, one frame is displayed and one detection target is contained within the frame, so that the detection target can be visibly shown. Therefore, when there are a plurality of detection targets, a plurality of frame images are displayed, and the detection targets can be surely visually recognized. By displaying the surveillance image on the display unit 112 in this way, it is possible to monitor the situation around the image information acquisition type fastening member 10 installed in the building even from a remote location. Also, when the panoramic image is a moving image, the control unit 22 continuously performs the analysis process by the analysis unit 29 while the moving image is being captured, and transmits the surveillance image information to the surveillance device 100 over time. Each time the surveillance device 100 receives the surveillance image information, it updates the surveillance image being displayed on the display unit 112.

[0059] As described above, since the image information acquisition type fastening member 10 is used for fastening members to each other and at the same time the imaging unit 20 captures the surroundings to acquire a panoramic image, it is possible to constantly monitor substantially any location in a monitoring target such as a structure including a building. Also, since analysis for detecting a detection target is performed from the panoramic image, it is possible to easily confirm loosening of the fastening body, corrosion, damage, dirt, deformation, displacement, foreign matter adhesion, etc. of the member via the surveillance device 100, and the time and labor required for an operator to inspect a structure or the like by visiting the site can be reduced. Also, the detection target detected in the monitoring target area can be confirmed through the surveillance image displayed on the display unit 112 of the surveillance device 100. Also, when a surveillance image that is a moving image is displayed, it is possible to confirm changes and the like of the detection target over time.

[0060] In the above-described embodiment, it has been described that the panoramic image is analyzed by the analysis unit of the image information acquisition type fastening member, but it is not limited to this, and the panoramic image may be analyzed by the surveillance device. Specifically, an analysis unit is provided in the surveillance device, and the surveillance device analyzes the panoramic image data received from the image information acquisition type fastening member by the analysis unit to detect a detection target. In this way, the processing load on the control unit of the imaging unit can be reduced, and the processing speed of the entire surveillance system can be improved.

[0061] Alternatively, the monitoring device 100 may perform image processing. That is, the imaging unit 20 includes an imaging unit 24 and a transmission / reception unit 30, and the monitoring device includes image processing means and analysis means, so that the imaging data acquired by the imaging unit is transmitted to the monitoring device. Then, the monitoring device may create panoramic image data from the imaging data and perform analysis of the panoramic image data.

[0062] Also, although the monitoring image displayed on the display unit 112 of the monitoring device 100 includes a panoramic image, only the detection target may be simply displayed. Even in this case, it is possible to confirm the presence of the detection target.

[0063] Alternatively, a server may be provided to manage data transmission and reception between the image information acquisition type fastening member and the monitoring device, and the server may perform analysis processing to detect the detection target. In that case, the unique ID, panoramic image data, position information, and azimuth information are transmitted from the image information acquisition type fastening member to the server. Then, in addition to the information received on the detection target detected by the server through analysis, it is also possible to create monitoring image information and transmit the monitoring image information to the monitoring device.

[0064] Even with the monitoring system constructed by such an image information acquisition type fastening member, monitoring device, and server, it is possible to easily confirm loosening of the fastening body, corrosion, damage, dirt, deformation, displacement, foreign object attachment, etc. of the member through the monitoring device, and reduce the time and effort required for the operator to visit the site to inspect structures and the like. Also, since the analysis processing is performed by the management server, it is possible to improve the processing speed of the entire monitoring system.

[0065] Alternatively, the image information acquisition type fastening member 10 may include an audio acquisition unit having a microphone or the like for acquiring ambient sound. In that case, by performing imaging and audio acquisition at the same time, it becomes possible to confirm abnormalities such as abnormal sounds that do not appear in the image.

[0066] Incidentally, although the imaging unit 20 has been described as being provided on the top surface of the head 14, it is not limited thereto, and may be provided on the tip side of the shaft portion 16 as shown in FIG. 6(a), or may be provided at both ends of the top surface of the head 14 and the tip surface of the shaft portion 16 as shown in FIG. 6(b). Further, the image information acquisition type fastening member 10 may have a fastening body 12 having only a shaft portion without a head, and the imaging unit 20 may be disposed on one end surface of the fastening body 12 as shown in FIG. 6(c), or the imaging unit 20 may be disposed on both end surfaces of the fastening body 12 as shown in FIG. 6(d). In such a case, the imaging unit 20 is set in shape and size so as to be accommodated inside the contour formed by the valleys of the male threads of the shaft portion 16 in the axial direction view.

[0067] Of course, the imaging unit 20 may be provided on the side surface of the head 14 (or the shaft portion 16). For example, as shown in FIG. 7(a), one or a plurality of recesses 60 are formed by recessing the circumferential surface of the head 14 radially inward, and the imaging unit 20 may be configured by disposing the imaging unit 24 in the recess 60. The imaging unit 24 is configured by arranging a plurality of them at predetermined intervals in the circumferential direction as shown in FIGS. 7(b) and 7(c). The depth of the recess 60 is set so that the imaging unit 24 does not protrude outside the circumferential surface of the head 14. Further, for power supply to the imaging unit 20, a hole may be provided on the top surface of the head 14 along the axis of the head 14 and capable of piercing a part of the recess 60, and the power supply and the imaging unit 20 may be connected through the hole.

[0068] Further, the monitoring target area imaged by the imaging unit 20 is not limited to all directions and can be set as appropriate. Further, an accessory shoe may be provided on the imaging unit 20, and a shoe mounting portion may be provided on the end surface of the head 14 or the shaft portion 16 of the fastening body 12, and the imaging unit 20 may be detachably held with respect to the fastening body 12 by inserting the accessory shoe into the shoe mounting portion. If the imaging unit 20 is detachable, the imaging unit 20 is removed when fastening the fastening body 12 to the member to be fastened. After tightening the fastener 12, the imaging unit 20 can be attached, so there is no risk of a tightening tool or the like coming into contact with the imaging unit 20, and the workability of tightening can be improved.

[0069] In addition, the image information acquisition type fastening member has a bolt-like fastener, but an imaging unit may be provided on a nut-shaped fastener. That is, the imaging unit 20 may be disposed on one end surface of the female screw portion 60 having a bag nut shape shown in FIG. 8. Also in this case, in the axial direction view, the shape and size of the imaging unit 20 are set so as to fit within the outer peripheral portion of the female screw portion 60. In addition, an imaging unit may be provided on a washer-shaped fastener. That is, it is possible to configure the imaging unit to be disposed on the end surface or the circumferential surface of the washer. In addition, the imaging unit may perform imaging according to an instruction received via the transmission / reception unit, and may further transmit panoramic image data stored in the storage unit based on the instruction. In this way, it is possible to capture or transmit an image at a desired timing by remote instruction via the monitoring device.

[0070] In addition, when the imaging unit 20 is provided on the top surface of the head, a light-transmissive cover surrounding the imaging unit 20 may be arranged. Here, FIG. 9 is a view showing an image information acquisition type fastening member 10 in which a light-transmissive cover 150 is arranged on the head 14. The light-transmissive cover 150 has a closed cross-sectional structure including a closed space, and surrounds the imaging unit 20 by the closed space. That is, as shown in FIG. 9, the light-transmissive cover 150 has a substantially cup shape, and by aligning the opening of the cup with the head 14, the imaging unit 20 is positioned in the inner space of the cup, and as a result, the imaging unit 20 can be surrounded. In this way, the light-transmissive cover 150 can be appropriately set as long as it has a shape capable of surrounding the imaging unit 20, and may be, for example, a substantially dome shape, a substantially cylindrical shape, a substantially conical shape, or the like.

[0071] In addition, the light-transmissive cover 150 can be formed of glass or a polymer compound or the like. The glass may include one or more of soda glass, quartz, sapphire, ruby, tempered glass, and lead glass. The high molecular compound may contain one or more of fluorine, polyester, polycarbonate, polyethylene terephthalate, polybutylene terephthalate, acrylic, polyether, vinyl, urethane, polyamide, and epoxy.

[0072] Also, by sealing between the light-transmitting cover 150 and the head 14 by a method such as screwing the end of the head 14 and the end of the light-transmitting cover 150, the dustproofness and waterproofness of the imaging unit 20 can be improved. That is, it is possible to prevent the intrusion of foreign substances such as liquid and fine dust from between the head 14 and the light-transmitting cover 150. Therefore, it becomes possible to improve the degree of freedom of the installation position of the image information acquisition type fastening member 10.

[0073] Note that the light-transmitting cover 150 may not only simply surround the imaging unit 20 but also have an antenna pattern on its surface. In this case, the antenna pattern is a non-powered element having an endless shape and is formed so as to be electromagnetically coupled with the imaging unit 20. Thereby, the imaging unit 20 can transmit and receive data via the antenna pattern. That is, in the transmission and reception processing performed by the transmission and reception unit 30, reception processing via the antenna pattern and transmission processing using the directivity of the antenna pattern can be performed.

[0074] Also, the antenna pattern can be formed by a conductive layer of a metal material mainly composed of any one or more of TiO, TiN, ITO, FTO, graphene, tin oxide, zinc oxide, indium tin oxide, etc. The formation of such an antenna pattern can be, for example, a method of patterning a metal material by photolithography or an etching method, or a method of forming by screen printing a conductive paste.

[0075] Also, the light-transmitting cover 150 may be provided with a half-mirror-like function. That is, if a part of the incident light from the outside is reflected, it is possible to suppress the occurrence of so-called halation or the like that makes the image captured by the imaging unit 20 unclear. Therefore, it is possible to improve the accuracy of detecting a detection target performed based on the captured image. In addition, it is possible to make it difficult to visually recognize the imaging unit 20 inside the translucent cover 150 from the outside. Further, by reflecting a part of the incident light from the outside, it is possible to suppress the photo-degradation of any substances existing inside the translucent cover 150, such as resin materials and metals. Also, a filter (for example, an infrared transmission filter, an ultraviolet transmission filter, etc.) that selectively transmits or blocks light of a specific wavelength may be provided on the translucent cover 150 or the imaging unit 20.

[0076] In addition, the image information acquisition type fastening member 10 or the monitoring device 100 may have a determination unit that determines the situation regarding the detection target. The determination unit may perform determination based on a preset determination criterion, or may improve the accuracy of the determination process by a learning process utilizing machine learning. Note that the situation regarding the detection target is, for example, the damage situation, the degree of progress of abnormalities in the detection target over time, etc. Also, the determination categories can be set as follows, for example. Determination category A: The detection target is not recognized or has a minor abnormality and no repair, etc. is required. Determination category B: Repair is required depending on the situation. Determination category C: From the perspective of preventive maintenance, it is necessary to perform repair, etc. promptly. Determination category D: From the perspective of safety, it is necessary to perform repair, etc. promptly. Determination category E: Emergency response is required from the perspective of safety. Determination category F: Other than that, emergency response is required. Determination category G: It is necessary to respond with maintenance work. Determination category H: Detailed investigation is required. Determination category I: Follow-up investigation is required. When such determination sections are set, the monitoring device 100 can perform a notification operation according to the determination result. Specifically, in the case of determination sections other than determination section A, it notifies that it is necessary to perform emergency response such as repair, maintenance work response, detailed investigation response, and follow-up investigation response. As a notification method, for example, the display unit 112 displays the determination section and the corresponding response content according to the section. It is also possible to perform notification by voice output from a speaker (not shown). Needless to say, the monitoring device 100 may simply notify that a detection target exists regardless of whether the determination is executed or not.
