DETAILED DESCRIPTION OF THE INVENTION

[0017] Hereinafter, embodiments of the present invention will be described with reference to the drawings. It should be noted that the embodiments are merely examples, and any modifications that a person skilled in the art could easily make while maintaining the gist of the invention are naturally included within the scope of the present invention. Furthermore, in order to clarify the explanation, the drawings may show the width, thickness, shape, etc. of each part more schematically than the actual embodiment. However, the shapes shown in the drawings are merely examples and do not limit the interpretation of the present invention.

[0018] In this specification and drawings, identical or similar components are represented by the same reference numeral. However, when the components are distinguished, the reference numeral may be accompanied by a capital letter. When a component is distinguished into multiple parts, the multiple parts may be accompanied by a lowercase letter or by a hyphen and a natural number.

[0019] First Embodiment A condition evaluation device 10 according to one embodiment of the present invention will be described with reference to FIGS.

[0020] 1. Usage of the Condition Evaluation Device 10 The manner in which the condition evaluation device 10 is used will be described with reference to FIGS.

[0021] Fig. 1 is a schematic diagram illustrating a state in which a user wears a condition evaluation device 10 according to one embodiment of the present invention. Fig. 2 is a schematic diagram illustrating a state in which a user evaluates the condition of an object to be inspected using a condition evaluation device 10 according to one embodiment of the present invention.

[0022] As shown in FIG. 1 , the condition evaluation device 10 includes an impact device 100, a control device 200, and a connection cable 300. The impact device 100 and the control device 200 are communicatively connected via the connection cable 300. However, the impact device 100 and the control device 200 may also be communicatively connected wirelessly. In this case, the connection cable 300 is not required. The configuration of the impact device 100 will be described in detail later. The impact device 100 strikes the surface of an object to be inspected and detects a tapping sound. A tapping sound detection signal corresponding to the tapping sound detected by the impact device 100 is transmitted to the control device 200 via the connection cable 300. The control device 200 can generate a control signal for controlling the operation of the impact device 100 and analyze the tapping sound detection signal. The control signal generated by the control device 200 and a determination result based on an analysis of the tapping sound detection signal are transmitted to the impact device 100 via the connection cable 300.

[0023] The control device 200 is provided with a power button 201 that starts or stops the impact of the impact device 100, and an operation mode switching button 202 that changes the operation mode of the impact device 100. When the user operates the power button 201, the impact of the impact device 100 on the surface of the object to be inspected starts or stops. The user can also operate the operation mode switching button 202 to select one of a plurality of different operation modes to evaluate the condition of the object to be inspected. The control device 200 is also provided with a determination display unit 204, and the user can check the determination result of the condition of the object to be inspected by looking at the display on the determination display unit 204.

[0024] Although not shown, a battery is connected to the control device 200. The battery may be built into the control device 200, or may be installed separately from the control device 200 and connected to the control device 200 via a connection cable. When the battery is built into the control device 200, it is preferable that the battery be a rechargeable battery such as a lithium-ion battery. The power required to operate the impact device 100 is supplied via a connection cable 300 from a battery connected to the control device 200.

[0025] The impact device 100 and the control device 200 are respectively equipped with a strap 103 and a strap 203. The strap 103 is closed so that the user's wrist can be placed around it. The strap 203 is also closed so that the user's neck can be placed around it. That is, when using the condition evaluation device 10, the user places the strap 103 around their wrist and holds the impact device 100. The user also places the strap 203 around their neck and hangs the control device 200 from their neck. The condition evaluation device 10 evaluates the condition of the inspection object while the user moves the impact device 100 themselves. By attaching the strap 103 to the impact device 100, even if the impact device 100 falls off the user's hand, the strap 103 supports the impact device 100, preventing it from falling to the ground and being damaged. Similarly, the strap 203 can prevent the control device 200 from falling to the ground and being damaged.

[0026] FIG. 2 illustrates an object to be inspected. For ease of explanation, the following description will be given assuming that the object to be inspected using the condition evaluation device 10 is an exterior wall 600 to which an exterior material 610 is adhered. However, the use of the condition evaluation device 10 is not limited to this. The object to be inspected may be a building or a structure such as an overpass or dam, and may be an exterior material or an interior material or flooring material. When using the condition evaluation device 10 to evaluate the condition of the exterior wall 600, a user moves a held impact device 100 along the surface of the exterior wall 600. The impact device 100 strikes the exterior material 610 of the exterior wall 600 and detects a tapping sound. The impact device 100 generates the detected tapping sound as a tapping sound detection signal. The generated tapping sound detection signal is analyzed by the control device 200 to determine the condition of the exterior wall 600. For example, if the exterior material 610 is not firmly adhered and is floating, an unusual tapping sound will be detected. In this case, the control device 200 can determine that the condition of the exterior wall 600 is abnormal. In this way, using the condition evaluation device 10, it is determined whether the condition of the exterior wall 600 is normal or abnormal. Note that the condition of the exterior wall 600 also corresponds to the condition of the exterior material 610, and therefore, hereinafter, the condition of the exterior material 610 may be referred to as the condition of the exterior wall 600 instead of the condition of the exterior wall 600.

[0027] The judgment result generated by the control device 200 is displayed on the judgment display unit 204. In addition, the judgment result generated by the control device 200 is transmitted to the impact device 100. The detailed configuration of the impact device 100 will be described later, but the impact device 100 is also provided with a judgment display unit. The judgment display unit of the impact device 100 is provided in a position where it can be seen by a user even when the user moves the impact device 100 along the exterior wall 600. The user can check the judgment result of the condition of the exterior wall 600 by looking at the display on the judgment display unit 204 or the judgment display unit of the impact device 100. The configuration of the judgment display unit 204 may be the same as the configuration of the judgment display unit of the impact device 100, which will be described later. It is sufficient that the judgment display unit is provided on at least one of the impact device 100 or the control device 200.

[0028] 1 and 2 show the configuration of the condition evaluation device 10 in which the impact device 100 and the control device 200 are separate and communicatively connected to each other via a connection cable 300, but the configuration of the condition evaluation device 10 is not limited to this. For example, the condition evaluation device 10 may have a configuration in which the impact device 100 and the control device 200 are integrated.

[0029] 2. Configuration of the impact device 100 The configuration of the impact device 100 of the condition evaluation device 10 will be described with reference to FIGS.

[0030] 3 and 4 are each a schematic side view showing the configuration of the impact device 100 of the condition evaluation device 10 according to one embodiment of the present invention. Specifically, FIG. 3 is a side view of the impact device 100 viewed from the x direction, and FIG. 4 is a side view of the impact device 100 viewed from the y direction. Here, the surface of the inspection object is parallel to the xy plane, and the normal direction of the surface of the inspection object corresponds to the z direction. Also, FIG. 5 is a schematic bottom view showing the configuration of the impact device 100 of the condition evaluation device 10 according to one embodiment of the present invention. The bottom side of the impact device 100 is in contact with the inspection object.

[0031] The percussion device 100 includes a percussion unit 110, a sound collection unit 120, wheels 130, a judgment display unit 140, and a handle unit 150. The detailed configuration of the percussion unit 110 will be described later, but the percussion unit 110 includes a main body 111 having a hollow interior. That is, the main body 111 has a cylindrical shape, with the z direction corresponding to the cylindrical direction. The main body 111 of the percussion unit 110 has a prismatic shape including one top surface and four side surfaces. Connecting members 161 with an L-shaped cross section are connected to two opposing side surfaces of the main body 111.

[0032] The sound collection unit 120 is connected to the lower part of the main body 111 of the percussion unit 110. The sound collection unit 120 has a structure that extends in four isotropic directions (+x direction, −x direction, +y direction, and −y direction) centered on the percussion unit 110. In this embodiment, an example will be described in which the x direction and the y direction are orthogonal to each other. A microphone 121 is disposed at each end of the sound collection unit 120 in each of the four directions in which the sound collection unit 120 extends. In other words, the percussion device 100 is equipped with four microphones 121. The microphones 121 of the sound collection unit 120 detect impact sounds generated when the percussion unit 110 strikes the surface of the test object and generate impact detection signals corresponding to the impact sounds. The impact detection signals are transmitted to the control device 200 via the connection cable 300, and the control device 200 analyzes the impact detection signals to determine the state of the test object. The determination result is transmitted via the connection cable 300 to the determination display unit 140 installed above the percussion unit 110. The determination display unit 140 lights up the light source 141 (for example, an LED) based on the determination result. For example, the determination display unit 140 can change the color of the light source 141 depending on the determination result. Specifically, the determination display unit 140 lights up the light source 141 in green when the condition of the inspection object is determined to be normal, and lights up the light source 141 in red when the condition of the inspection object is determined to be abnormal. This allows the user to check the determination result of the condition of the inspection object by looking at the color of the light source 141.

[0033] The percussion device 100 includes four wheels 130. Two of the wheels 130 are connected to a connecting member 161 that is connected to one side of the main body 111 via a rotation shaft 162. Similarly, the remaining two wheels 130 are connected to a connecting member 161 that is connected to the other side of the main body 111 via a rotation shaft 162. That is, each of the four wheels 130 is connected to the connecting member 161 so as to be rotatable about the rotation shaft 162 that extends in the z direction. Furthermore, one microphone 121 is located between two adjacent wheels 130 of the four wheels 130.

[0034] The wheels 130 are means for moving the impact device 100. By rotating the wheels 130 around the rotation shafts 162, the user can move the impact device 100 in any direction within the xy plane. For example, the wheels 130 are casters, but are not limited to this.

[0035] The impact device 100 also includes a bottom cover 170 below the impact unit 110 and the sound collection unit 120. The bottom cover 170 is connected to at least one of the impact unit 110 and the sound collection unit 120. The bottom surface of the bottom cover 170 is preferably positioned slightly above the ground contact surface of the wheels 130. The bottom cover 170 has an opening 171 penetrating the top and bottom surfaces. The planar shape of the opening 171 is, for example, circular, but is not limited to this. The opening 171 may have any planar shape that allows the impact head 112 and impact head cover 113 of the impact unit 110 to pass through. In other words, in a plan view (bottom view), the bottom cover 170 has an opening 171 through which the impact head 112 and impact head cover 113 of the impact unit 110 are exposed. The outer shape of the bottom cover 170 is, for example, rectangular, but is not limited to this.

[0036] The bottom cover 170 is made of a material that does not damage the surface of the object to be inspected. For example, the bottom cover 170 can be made of a resin such as vinyl chloride, vinyl acetate, polycarbonate, polystyrene, polyethylene, polypropylene, polyamide, or nylon.

[0037] [3. Configuration of handle portion 150] The configuration of the handle portion 150 will be described with reference to FIG. 6 as well as FIG.

[0038] FIG. 6 is a schematic top view illustrating a method for gripping the handle portion 150 of the impact device 100 of the condition evaluation device 10 according to one embodiment of the present invention.

[0039] The handle portion 150 includes a gripping member 151 and a protruding member 152. The gripping member 151 is connected to the main body 111 of the striking portion 110. As shown in FIG. 6, the gripping member 151 has a U-shaped cross section that surrounds three sides of the main body 111 and is connected to the main body 111. The protruding member 152 is connected to the gripping member 151 so as to protrude from the gripping member 151 in the y direction. The gripping member 151 includes a first finger contact surface 151a that comes into contact with the user's thumb and a second finger contact surface 151b that comes into contact with the user's fingers other than the thumb (e.g., the index finger and middle finger). The second finger contact surface 151b is located on the opposite side of the first finger contact surface 151a, with the main body 111 sandwiched therebetween. The protruding member 152 is connected to the surface of the gripping member 151 other than the first finger contact surface 151a and the second finger contact surface 151b. The protruding member 152 includes a palm contact surface 152a that contacts the palm of the user and a recess 152b that contacts the fingers other than the thumb (e.g., the ring finger). The palm contact surface 152a is located at the end of the protruding member 152 and is curved so as to bulge outward from the protruding member 152. The recess 152b is formed in the lower part of the protruding member 152.

[0040] The gripping member 151 is preferably made of an elastic material that is stretchable and can absorb shock. Furthermore, the first finger contact surface 151a and the second finger contact surface 151b of the gripping member 151 preferably have high frictional force. With such a configuration of the gripping member 151, the user can firmly grip the main body 111 of the vibrating percussion unit 110 without their fingers slipping. For example, the gripping member 151 may be made of silicone rubber, but is not limited to this. Furthermore, the first finger contact surface 151a and the second finger contact surface 151b of the gripping member 151 may be provided with unevenness to increase frictional force, or may be provided with recesses into which the user's fingers can fit.

[0041] When using the condition evaluation device 10, the user places their thumb on the first finger contact surface 151a of the gripping member 151 and their index finger and middle finger on the second finger contact surface 151b. The user also places their palm on the palm contact surface 152a of the protruding member 152, pressing the palm contact surface 152a and placing their ring finger in the recess 152b. The impact device 100 is supported and held from three directions: the first finger contact surface 151a, the second finger contact surface 151b, and the palm contact surface 152a. This allows the user to firmly grip the vibrating impact device 100.

[0042] In this embodiment, the user can move the impact device 100 along the surface of the object to be inspected while firmly gripping the handle 150 of the impact device 100. Furthermore, even when the user grips the handle 150 of the impact device 100, the light source 141 of the result display unit 140 installed on the top of the main body 111 is not covered. Therefore, while moving the impact device 100, the user can see the light of the light source 141, which displays the result, and check the condition of the object to be inspected on the spot.

[0043] 4. Configuration of the striking unit 110 Fig. 7 is a schematic diagram showing the internal structure of the impact unit 110 of the impact device 100 of the condition evaluation device 10 according to one embodiment of the present invention. For ease of explanation, Fig. 7 shows a cross-sectional view of part of the configuration (the hatched portion in Fig. 7).

[0044] The striking unit 110 includes a main body 111, a striking head 112, a striking head cover 113, a support member 114, a rod 115, an actuator 116, a striking head cover fixing member 117, and a striking force sensor 118. The striking head 112, the striking head cover 113, the support member 114, the rod 115, the actuator 116, the striking head cover fixing member 117, and the striking force sensor 118 are arranged inside the main body 111. As described above, the main body 111 has a rectangular column shape, but the shape of the main body 111 is not limited to this. For example, the main body 111 may have a cylindrical shape. The rod 115 is inserted through the actuator 116. The actuator 116 is connected to and supported by the support member 114, which is connected to the inner wall of the main body 111. The actuator 116 receives a control signal from the control device 200 via the connection cable 300 and drives the rod 115 so that the rod 115 moves (moves up and down) in the z direction based on the control signal. The striking head 112 is connected to the end of the rod 115 via an impact force sensor 118. Therefore, as the rod 115 moves up and down, the striking head 112 also moves up and down. A striking head cover fixing member 117 is connected to the striking head 112, and the striking head cover 113 is attached and fixed to the striking head cover fixing member 117. It is preferable that the striking head cover 113 be detachably attached to the striking head cover fixing member 117 so that it can be replaced.

[0045] The striking head cover 113 has an opening 113a. The striking head 112 is arranged to be inserted through the opening 113a of the striking head cover 113, and the tip of the striking head 112 is positioned below the lower end of the striking head cover 113 and is exposed from the striking head cover 113.

[0046] The striking head 112 is made of a material that is difficult to deform, such as metal. When the striking head 112 strikes, the tip of the striking head 112 comes into contact with the surface of the object being inspected. To deliver a momentary strike to the surface of the object being inspected, it is preferable that the contact area between the tip of the striking head 112 and the surface of the object being inspected is small. For this reason, it is preferable that the tip of the striking head 112 is curved, such as in a spherical shape. As described above, the tip of the striking head 112 is exposed from the striking head cover 113, but the periphery of the striking head 112 is covered by the striking head cover 113.

[0047] The impact force sensor 118 detects the impact force that the impact head 112 receives from the surface of the test object, and generates an impact force detection signal. The generated impact force detection signal is transmitted to the control device 200 via the connection cable 300. For example, the impact force sensor 118 is a piezoelectric sensor.

[0048] The striking head cover 113 has a structure in which an upper disc shape is combined with a lower inverted truncated cone shape, with an opening 113a passing through the center of each of the disc shape and the inverted truncated cone shape. The upper surface of the striking head cover 113 is connected to the striking head cover fixing member 117 of the striking part 110, and the striking head cover 113 is fixed to the striking head cover fixing member 117. The striking head cover 113 may be fixed to the striking head cover fixing member 117 by adhesive or by screw fastening. Although not shown, an engaging member for engaging with the striking head cover fixing member 117 may be provided on the upper surface of the striking head cover 113. Providing the engaging member on the striking head cover 113 makes it easier to align the striking head cover 113 and the striking head cover fixing member 117, making it easier to attach the striking head cover 113 to the striking head cover fixing member 117.

[0049] The side of the lower part of the striking head cover 113 (i.e., the side of the inverted truncated cone shape) has a tapered shape. Specifically, the side of the striking head cover 113 is inclined so that the outer circumference of the striking head cover 113 increases from the lower end of the striking head cover 113 toward the top.

[0050] The striking head cover 113 is made of a different material than the striking head 112. The striking head cover 113 is made of a material that is more flexible than the striking head 112. Furthermore, the striking head cover 113 is preferably made of a material with a certain degree of rigidity so that it does not damage the object being inspected upon contact with it and does not deteriorate itself. For example, the striking head cover 113 can be made of a resin such as vinyl chloride, vinyl acetate, polycarbonate, polystyrene, polyethylene, polypropylene, polyamide, or nylon. When the upper (disk-shaped) and lower (frusto-conical) parts of the striking head cover 113 are formed separately, the upper (disk-shaped) and lower (frusto-conical) parts may be made of the same material or different materials. Furthermore, the striking head cover 113 may be made of the same material as the bottom cover 170 or different materials.

[0051] 5. Striking Operation of Striking Unit 110 8 and 9 are schematic diagrams illustrating the impact operation of the impact unit 110 of the impact device 100 of the condition evaluation device 10 according to one embodiment of the present invention. For ease of explanation, a portion of the configuration (the hatched portion in FIGS. 8 and 9) is shown as a cross-sectional view in FIGS. 8 and 9. In addition, in FIG. 8, the state of the impact unit 110 before the impact operation is shown by a dotted line.

[0052] The actuator 116 drives the rod 115 so that it moves in the z direction (up and down). In a steady state (before the striking unit 110 performs a striking operation), the striking head 112 and striking head cover 113 are positioned above the top surface of the bottom cover 170. The tip of the striking head 112 does not protrude from the opening 171 in the bottom cover 170. When the striking unit 110 starts a striking operation, the rod 115 moves downward, and the tip of the striking head 112 protrudes from the opening 171 in the bottom cover 170. The tip of the striking head 112 protruding from the opening 171 in the bottom cover 170 can strike the surface of the object being inspected. The striking head cover 113 is attached to a striking head cover fixing member 117 connected to the striking head 112 and moves downward in accordance with the downward movement of the striking head 112. A portion of the striking head cover 113 protrudes from the opening 171 in the bottom cover 170.

[0053] 8 shows the state of the striking part 110 when the rod 115 has moved at its maximum stroke. When the tip of the striking head 112 strikes the surface of the test object, the striking head 112 receives a resistance force from the surface of the test object corresponding to the striking force, so only the tip of the striking head 112 may protrude from the opening 171 of the bottom cover 170.

[0054] The striking action of the striking unit 110 may be repeated, in which case it is preferable that the actuator 116 periodically moves the rod 115 up and down (raise and lower). The striking action of the striking unit 110 can be changed by operating the operation mode switching button 202 of the control device 200. For example, the frequency of the striking action can be changed by operating the operation mode switching button 202.

[0055] The state of the striking part 110 shown in Figure 9 is a state in which the tip of the striking head 112 is depressed into a joint 620 in the exterior wall 600. The joint 620 is formed between two exterior materials 610. Note that a joint material has been applied to the joint 620 shown in Figure 9.

[0056] As shown in FIG. 9 , even if the tip of the striking head 112 falls into the joint 620, in the striking device 100, the striking head cover 113 covers the side end of the striking head 112, and the striking head cover 113 comes into contact with the corner or surface of the exterior material 610. In other words, the striking head cover 113 covers the corner of the joint 620 (the corner of the exterior material 610). Therefore, in the striking device 100, the striking head 112 does not come into contact with the corner of the joint 620. Furthermore, because the striking head cover 113 comes into contact with the corner of the joint 620 before the rod 115 extends to its maximum stroke, the striking head 112 does not strike the bottom surface of the joint 620 (or the joint material). In other words, in the striking device 100, it is possible to prevent the striking head 112 from striking the corner or bottom surface of the joint 620 instead of the surface of the exterior material 610 to perform a condition evaluation. Furthermore, because the striking head cover 113 deforms upon contact with the corners of the joint 620, the striking force caused by the striking head cover 113 coming into contact with the corners of the joint 620 is small, and the striking force detected by the striking force sensor 118 is also small. As will be described in detail below, in the condition evaluation process using the condition evaluation device 10, an inspection object is determined when the striking force of the striking force detection signal exceeds a threshold. In other words, the striking force when the striking head 112 strikes the joint 620 is small and does not exceed the threshold, so an inspection object is not determined. Therefore, the condition evaluation device 10 can prevent erroneous condition evaluation when striking the joint 620 rather than the exterior material 610.

[0057] 6. Condition evaluation process of inspection object using condition evaluation device 10 FIG. 10 is a flowchart showing a condition evaluation process for an inspection object using the condition evaluation device 10 according to one embodiment of the present invention.

[0058] The condition evaluation process shown in FIG. 10 begins when a user moves the impact device 100 to a predetermined position while bringing the wheels 130 of the impact device 100 into contact with the surface of the object to be inspected (e.g., the exterior wall 600), and then operates the power button 201 of the control device 200. When the power button 201 is operated, a control signal for starting the impact operation of the impact head 112 is sent from the control device 200 to the actuator 116, and the rod 115 begins to periodically move up and down. This starts the impact operation of the impact head 112. The up and down movement of the impact head 112 continues until the power button 201 is operated again. While the condition evaluation process is being performed by the condition evaluation device 10, the user can move the impact device 100 along the surface of the object to be inspected.

[0059] The state evaluation process shown in Figure 10 includes steps S110 to S140. Steps S110 to S140 are repeatedly executed while the striking head 112 is performing a striking operation. Steps S110 to S150 will be explained in order below.

[0060] In step S110, the microphone 121 of the sound collection unit 120 detects the tapping sound and generates a tapping sound detection signal corresponding to the tapping sound. The generated tapping sound detection signal is transmitted to the control device 200.

[0061] In step S120, the impact force sensor 118 detects the impact force and generates an impact force detection signal corresponding to the impact force. The generated impact force detection signal is sent to the control device 200.

[0062] In step S130, the control device 200 converts the impact force detection signal into an impact force detection waveform and calculates the maximum impact force. The control device 200 also determines whether the maximum impact force is equal to or greater than a threshold value. When the impact head 112 strikes the surface of the exterior wall 600, the movement distance of the impact head 112 differs from when the impact head 112 strikes the surface of the exterior material 610 and when the impact head 112 strikes the joint 620, resulting in a different impact force detected by the impact force sensor 118. When the impact head 112 strikes the surface of the exterior material 610 reliably, the resistance force the impact head 112 receives from the surface increases, resulting in a higher impact force detected by the impact force sensor 118. In contrast, when the impact head 112 strikes the joint 620, the resistance force the impact head 112 receives from the joint 620 decreases, resulting in a lower impact force detected by the impact force sensor 118. Therefore, by determining whether the maximum impact force is equal to or greater than a threshold value, it is possible to determine whether the impact head 112 reliably struck the surface of the object being inspected. In the impact device 100, when the impact head 112 strikes the joint 620, the impact head cover 113 may come into contact with the corner of the joint 620. However, the impact head cover 113 is flexible and can be significantly deformed. In this case, the resistance force that the impact head 112 receives from the joint 620 is small, and the impact force detected by the impact force sensor 118 is also small.

[0063] If the maximum impact force is equal to or greater than the threshold value (step S130: YES), step S140 is performed. If the maximum impact force is less than the threshold value (step S130: NO), one state evaluation process ends, but if the impact operation of the impact head 112 continues, the process returns to step S110, and steps S110 to S140 are repeatedly executed.

[0064] In step S140, the control device 200 converts the tapping detection signal into a tapping detection waveform. Because the impact device 100 has four microphones 121, the control device 200 generates four converted tapping detection waveforms. The control device 200 can determine the state of the inspection object based on the four converted tapping detection waveforms. For example, the control device 200 determines the state of the inspection object based on the maximum amplitude of each of the four tapping detection waveforms (for example, the amplitude of the first waveform cycle) and generates a determination result. Note that a conventional method can be used to generate the determination result of the state of the inspection object.

[0065] The judgment result is displayed on the judgment display unit 204 of the control device 200. Therefore, the user can check the judgment result of the state of the exterior wall 600 by looking at the judgment display unit 204. The judgment result is also transmitted to the judgment display unit 140 of the impact device 100. The judgment display unit 140 turns on the light source 141 based on the judgment result. The user can check the judgment result of the state of the exterior wall 600 by looking at the lighting of the light source 141 (for example, the color of the light source 141).

[0066] In the condition evaluation device 10, the impact device 100 includes a handle 150, and the first finger contact surface 151a, the second finger contact surface 151b, and the palm contact surface 152a of the handle 150 allow the user to firmly grip the impact device 100. Holding the handle 150 in this manner prevents the user's hand from covering the light source 141, allowing the user to see the light source 141 illuminate and confirm the assessment result of the condition of the object being inspected. Furthermore, the impact device 100 includes an impact head cover 113 that covers the side end of the impact head 112. This allows the condition evaluation device 10 to move smoothly even when a joint 620 is present, and prevents erroneous assessments due to striking the joint 620.

[0067] <Variation 1> 11 and 12, a modified example of the condition evaluation device 10 will be described. Specifically, an impact device 100A, which is a modified example of the impact device 100 of the condition evaluation device 10, will be described below. Note that, in the following, when the configuration of the impact device 100A is the same as the configuration of the impact device 100, the description of the configuration of the impact device 100A may be omitted.

[0068] Fig. 11 is a schematic side view showing the configuration of the impact device 100A of the condition evaluation device 10 according to one embodiment of the present invention. Fig. 12 is a schematic top view illustrating a method for gripping the handle 150A of the impact device 100A of the condition evaluation device 10 according to one embodiment of the present invention.

[0069] As shown in FIG. 11 , the striking device 100A includes a handle 150A. The handle 150A includes a support member 153 and a gripping member 154. The support member 153 has a flat plate shape and has an opening in the center through which the main body 111 of the striking part 110 is inserted. That is, the main body 111 is inserted into the support member 153 and is connected to the main body 111. The support member 153 may be composed of a single member or may be composed of multiple members joined together. The support member 153 supports the gripping member 154. The gripping member 154 is formed on the support member 153 and has a shape that widens from top to bottom and curves outward. The gripping member 154 also includes a recess 154a that the user's thumb rests against. For example, resins such as vinyl chloride, vinyl acetate, polycarbonate, polystyrene, polyethylene, polypropylene, polyamide, or nylon can be used as the material of gripping member 154. The surface of gripping member 154 may be provided with irregularities to increase frictional force.

[0070] As shown in FIG. 12, when using the impact device 100A, the user places the fingers and palm of the hand on the gripping member 154. The user places the thumb inside the recess 154a and grips the gripping member 154. By holding the impact device 100A in this manner, the user can firmly grasp the vibrating impact device 100A. Furthermore, even when the user grips the handle 150A of the impact device 100A, the light source 141 of the determination display unit 140 located on the top of the main body 111 is not covered. Therefore, the user can move the impact device 100A and see the light source 141 turn on, allowing them to immediately check the determination result of the condition of the test object.

[0071] The impact device 100A of the condition evaluation device 10 also includes a handle 150A, and the user can firmly hold the impact device 100A by grasping the gripping member 154 of the handle 150A. Furthermore, by holding the handle 150A in this manner, the user's hand does not cover the light source 141, and the user can see the light of the light source 141 and confirm the determination result of the condition of the object to be inspected.

[0072] <Variation 2> 13 and 14, another modified example of the condition evaluation device 10 will be described. Specifically, the following describes an impact device 100B, which is a modified example of the impact device 100 of the condition evaluation device 10. Note that, in the following, when the configuration of the impact device 100B is the same as the configuration of the impact device 100, the description of the configuration of the impact device 100B may be omitted.

[0073] 13 and 14 are each a schematic side view showing the configuration of the impact device 100B of the condition evaluation device 10 according to one embodiment of the present invention. Specifically, FIGS. 13 and 14 are side views of the impact device 100B as viewed from the y direction.

[0074] As shown in FIG. 13, the impact device 100B includes a handle 150B. The handle 150B includes a support member 155 and a gripping member 156. The support member 155 is connected to the side of the main body 111 of the impact part 110 and extends in a direction intersecting the tubular direction of the main body 111. The support member 155 does not extend parallel to the surface of the test object, but rather extends in a direction at a predetermined angle relative to the surface of the test object. The gripping member 156 is provided at the end of the support member 155. The gripping member 156 includes a plurality of recesses 156a in its lower portion that the user's fingers rest against.

[0075] When using the impact device 100B, the user places their fingers on the recess 156a and grips the gripping member 156. By gripping the impact device 100B in this manner, the user can firmly hold the vibrating impact device 100B. Furthermore, even when the user grips the handle 150B of the impact device 100B, the light source 141 of the determination display unit 140 located on the top of the main body 111 is not covered. Therefore, the user can move the impact device 100B and see the light of the light source 141 turn on, allowing them to immediately check the determination result of the condition of the object being inspected.

[0076] Although the handle portion 150B shown in FIG. 13 is provided on the side surface of the main body 111 of the striking unit 110, the position at which the handle portion 150B is provided is not limited to this. As shown in FIG. 14, the handle portion 150B may be provided on the upper portion of the main body 111. For example, the handle portion 150B further includes an angle adjustment member 157. The angle adjustment member 157 is provided on the upper portion of the main body 111 and can adjust the angle of the extending direction of the support member 155 connected to the angle adjustment member 157. However, with the configuration of the striking device 100B shown in FIG. 14, the determination display unit 140 cannot be provided on the upper portion of the main body 111, so the determination display unit 140 is provided on the side surface of the main body 111.

[0077] The impact device 100B of the condition evaluation device 10 also includes a handle 150B, and the user can firmly hold the impact device 100B by gripping the gripping member 156 of the handle 150B. Furthermore, by holding the handle 150B in this manner, the user's hand does not cover the light source 141, and the user can see the light of the light source 141 and confirm the determination result of the condition of the object to be inspected.

[0078] <Variation 3> 15, a further modified example of the condition evaluation device 10 will be described. Specifically, a description will be given below of an impact device 100C, which is a modified example of the impact device 100 of the condition evaluation device 10. Note that, in the following, when the configuration of the impact device 100C is the same as the configuration of the impact device 100, the description of the configuration of the impact device 100C may be omitted.

[0079] Fig. 15 is a schematic side view showing the configuration of the impact device 100C of the condition evaluation device 10 according to one embodiment of the present invention. Specifically, Fig. 15 is a side view of the impact device 100C as viewed from the y direction.

[0080] As shown in Figure 15, the striking device 100C includes a handle 150C. The handle 150C includes a connecting member 158 and a rod-shaped member 159. The connecting member 158 is attached to the side of the main body 111 of the striking part 110. The connecting member 158 connects the rod-shaped member 159 to the main body 111. The rod-shaped member 159 connected to the main body 111 extends substantially parallel to the contact surface of the wheel 130. The surface of the rod-shaped member 159 may be provided with irregularities to increase frictional force.

[0081] When using the impact device 100C, the user holds it as if gripping the rod-shaped member 159. By holding the impact device 100C in this manner, the user can firmly grip the vibrating impact device 100C. Furthermore, even when the user holds the handle 150C of the impact device 100C, the light source 141 of the determination display unit 140 installed on the top of the main body 111 is not covered. Therefore, the user can move the impact device 100C and see the light of the light source 141 turn on, allowing them to immediately check the determination result of the condition of the object being inspected.

[0082] The impact device 100C of the condition evaluation device 10 also includes a handle 150C, and the user can firmly hold the impact device 100C by gripping the rod-shaped member 159 of the handle 150C. Furthermore, by holding the handle 150C in this manner, the user's hand does not cover the light source 141, and the user can see the light of the light source 141 and confirm the determination result of the condition of the object to be inspected.

[0083] Second Embodiment A condition evaluation system 20 according to one embodiment of the present invention will be described with reference to FIGS.

[0084] FIG. 16 is a schematic diagram illustrating the configuration of a condition evaluation system 20 according to one embodiment of the present invention.

[0085] 16, the condition evaluation system 20 includes the components of the condition evaluation device 10 (the impact device 100, the control device 200, and the connection cable 300), as well as an imaging device 400 and an information processing device 500. The information processing device 500 is communicably connected to the control device 200 and the imaging device 400 via a wired or wireless connection. Therefore, the information processing device 500 can receive the determination result generated by the control device 200 and the image captured by the imaging device 400.

[0086] The condition evaluation system 20 uses a first marker 410 and a second marker 420. The first marker 410 is attached to the impact device 100. The first marker 410 functions as a landmark indicating the position of the impact device 100 as the user moves. The position where the condition of the inspection object is evaluated overlaps with the impact device 100, so the first marker 410 attached to the impact device 100 corresponds to the position where the condition of the inspection object is evaluated. For example, the first marker 410 is attached to the upper part of the main body 111 of the impact unit 110, but this is not limited thereto. The first marker 410 may be attached to a position where it can be imaged by the imaging device 400. Furthermore, if a part of the impact device 100 has a special pattern or color, that pattern or color may be used as the first marker 410. On the other hand, the second marker 420 is attached to the exterior wall 600. When the object to be inspected has a large area, it may be difficult to evaluate the condition of the entire surface at once. Therefore, in such cases, second markers 420 are placed on the exterior wall 600 to define an evaluation area for evaluating the condition of the object to be inspected. It is preferable to use a plurality of second markers 420. For example, as shown in FIG. 16 , when two second markers 420 are placed on the exterior wall 600, a rectangular area with the two second markers 420 as diagonals can be defined as the evaluation area. The second markers 420 only need to be placed in a position where they can be imaged by the imaging device 400.

[0087] The first marker 410 and the second marker 420 may be two-dimensional codes such as a QR code (registered trademark) or an AR code.

[0088] The information processing device 500 can execute arithmetic processing based on a program. The information processing device 500 is, for example, a computer. The computer includes, for example, a central processing unit (CPU) as arithmetic means and a storage device as storage means. The storage device is, for example, a random access memory (RAM), a read only memory (ROM), or a hard disk drive (HDD).

[0089] In the condition assessment device 10, the user can check the assessment result of the condition of the exterior wall 600 on the spot by looking at the light source 141 of the assessment display unit 140, but in the condition assessment system 20, the assessment results within the assessment target area, which is part of the exterior wall 600, are collected and an assessment data map 510 is generated in which the assessment results are visualized. The generation of the assessment data map 510 by the information processing device 500 will be described below.

[0090] First, the information processing device 500 receives an image captured by the imaging device 400 and acquires the second marker 420 in the image. Based on the second marker 420, the information processing device 500 defines an evaluation target area as an area of ​​the exterior wall 600 where the impact by the impact device 100 will be performed.

[0091] Next, the information processing device 500 acquires a first marker 410 in the image. The information processing device 500 detects the position of the impact device 100 based on the first marker 410. Because the first marker 410 is acquired as position coordinates based on the evaluation target area, the information processing device 500 can acquire position information of the impact device 100 within the evaluation target area. The information processing device 500 also receives the determination result from the control device 200. This allows the information processing device 500 to generate evaluation data in which the detected position information of the impact device 100 is associated with the determination result. Furthermore, the information processing device 500 can generate an evaluation data map 510 in which the determination result is represented in association with the movement path of the impact device 100 within the evaluation target area, based on the position information of the impact device 100 in the evaluation data.

[0092] In the condition evaluation system 20, the user can later check the evaluation results of the condition of the exterior wall 600 (or the condition of the exterior material 610) by looking at the evaluation data map 510 generated by the information processing device 500 without checking whether the light source 141 of the evaluation display unit 140 is lit.

[0093] FIG. 17 is a schematic diagram illustrating the combination of a plurality of evaluation data maps 510 in the condition evaluation system 20 according to one embodiment of the present invention.

[0094] As described above, the condition evaluation system 20 can define an evaluation target area using the second marker 420, so it is possible to divide the exterior wall 600 into multiple areas and generate an evaluation data map 510 for each of the multiple evaluation target areas. FIG. 17 shows four generated evaluation data maps 510 (first evaluation data map 510-1 to fourth evaluation data map 510-4). Taking the first evaluation target area corresponding to the first evaluation data map 510-1 as a reference, the second evaluation target area corresponding to the second evaluation data map 510-2 is located to the right of the first evaluation target area. Similarly, the third evaluation target area corresponding to the third evaluation data map 510-3 and the fourth evaluation target area corresponding to the fourth evaluation data map 510-4 are located below and to the lower right of the first evaluation target area, respectively. The information processing device 500 can combine the first evaluation data map 510-1 to the fourth evaluation data map 510-4 based on the position information of the evaluation target area, and generate an overall evaluation data map 520 that represents the assessment results of the condition of the entire exterior wall 600.

[0095] In this way, even if the object to be inspected has a large area, the user can check the judgment results of the overall condition of the object to be inspected by looking at the overall evaluation data map 520 generated by the information processing device 500.

[0096] <Variation 1> In the condition evaluation process by the information processing device 500 of the condition evaluation device 10, an evaluation value can be generated as a judgment parameter based on the impact sound detection signal and the impact force detection signal. For example, the evaluation value E can be calculated using the maximum impact force F and the maximum amplitude value A according to the following formulas (1) to (3). Fr=F / F0 (1) Ar=A / A0 (2) E=(Ar) i / (Fr) j (i=1, j=1 / 2) (3)

[0097] The striking force of the striking head 112 may vary depending on the orientation of the striking device 100. Therefore, to reduce the variation in the striking force of the striking head 112, a reference striking force F0 is set by averaging the striking forces produced when the orientation of the striking device 100 is changed. Similarly, because the sensitivity of the microphones 121 varies from one to another, a reference striking force A0 is set by averaging the maximum amplitude values ​​of the four microphones 121. By introducing these set values, the evaluation value E becomes less susceptible to the influence of variation.

[0098] In the information processing device 500 of the condition evaluation system 20, a wireframe model can also be created using the evaluation value E instead of the evaluation data map 510 based on the determination results.

[0099] The wireframe model is generated by plotting the first axis (x-axis) and second axis (y-axis) of a three-dimensional Cartesian coordinate system in the direction of extension of the surface of the object to be inspected, plotting the evaluation value corresponding to the position information of the impact device 100 on the third axis (z-axis), and connecting the evaluation values ​​of adjacent position information. The control device 200 cuts the wireframe model along the first and second axes at a point on the third axis where a predetermined threshold value is obtained, and evaluates whether the state of the object to be inspected differs with the cut cross section as a boundary.

[0100] Even in the case of evaluation using a wireframe model, the user can later check the condition of the exterior wall 600 (or the condition of the exterior material 610) by looking at the wireframe model generated by the information processing device 500. In particular, in the case of a wireframe model, by adjusting the threshold value, it becomes possible to identify not only the area where peeling of the exterior material 610 has occurred but also the boundary of the peeling, thereby enabling more detailed identification of the location where an abnormality has occurred.

[0101] The above-described embodiments can be implemented by appropriately combining the configurations as long as they are not mutually contradictory. Furthermore, even if a person skilled in the art appropriately adds or deletes the configuration or modifies the design based on the embodiments, or adds or omits a process or modifies conditions, such addition or deletion of the configuration or modification of conditions is included in the scope of the present invention as long as the gist of the present invention is maintained.

[0102] Even if there are other effects and advantages different from those brought about by the above-described embodiments, those that are clear from the description in this specification or that can be easily predicted by a person skilled in the art are naturally understood to be brought about by the present invention.
