Summary of the Invention

Problems to be Solved by the Invention

[0005] In diagnostic devices such as those described in Patent Documents 1 and 2, the belts of belt conveyors and structures (buildings, buildings, bridge piers, etc.), which are the objects of diagnosis, are devices and structures related to construction and civil engineering. Therefore, the area to be diagnosed tends to be relatively large and the use tends to continue for a relatively long period. In a system including such a diagnostic device, the information on the object acquired for diagnosis and monitoring becomes extremely large in volume, and there is a risk that the load when the information is processed by the diagnostic device becomes excessive.

[0006] The present invention was made against the background of the above-mentioned problems, and aims to provide a processing apparatus that can share the processing of information about an object, and a control method for the said processing apparatus. [Means for solving the problem]

[0007] The processing apparatus according to the present invention is a processing apparatus (20) that processes detection information detected by a detection device (10) that detects light or sound reflected from an object (1) and transmits it to a diagnostic device (30) that diagnoses the object using wireless communication, and includes an acquisition unit (20a) that acquires the detection information and an execution unit (20b) that performs a transmission process to process and transmit the detection information, wherein in the transmission process, the detection information acquired by the acquisition unit (20a) is analyzed, average value information relating to the average value of the detection information is acquired for each predetermined area of ​​the object (1), and predetermined information based on the average value information is transmitted to the diagnostic device (30).

[0008] With this configuration, the processing unit performs a transmission process, which analyzes the detection information acquired by the acquisition unit. Average value information is then obtained for each predetermined area of ​​the object, and predetermined information based on this average value information is transmitted to the diagnostic device. This allows the processing unit to handle the analysis of detection information and the acquisition of average value information, thereby reducing the processing load on the diagnostic device. Furthermore, using average value information for the average value of detection information in the diagnosis reduces detection errors and improves diagnostic accuracy.

[0009] The present invention relates to a control method for a processing apparatus, which processes detection information detected by a detection device (10) that detects light or sound reflected from an object (1) and transmits it to a diagnostic device (30) that diagnoses the object using wireless communication. The processing apparatus is capable of performing an acquisition step to acquire the detection information and an execution step to perform a transmission process to process and transmit the detection information. In the transmission process, the detection information acquired in the acquisition step is analyzed, average value information relating to the average value of the detection information is acquired for each predetermined area of ​​the object (1), and predetermined information based on the average value information is transmitted to the diagnostic device (30).

[0010] With this configuration, the control method of the processing unit involves a transmission process in which the detection information acquired by the acquisition unit is analyzed, average value information relating to the average value of the detection information is acquired for each predetermined area of ​​the object, and predetermined information based on the average value information is transmitted to the diagnostic device. As a result, the processing unit can share the task of analyzing the detection information and acquiring average value information relating to the average value, thereby reducing the processing load on the diagnostic device. Furthermore, by using average value information relating to the average value of the detection information in the diagnosis, the detection error of the detection information can be reduced, improving the accuracy of the diagnosis.

[0013] Hereinafter, examples of embodiments of the diagnostic system (100) according to the present invention, the detection device (10), the processing device (20), and the diagnostic device (30) constituting the diagnostic system (100) will be described with reference to Figures 1 to 9. Note that the configurations and operations of the embodiments described below are examples, and the present invention is not limited to such configurations and operations. In addition, similar or identical descriptions will be simplified or omitted as appropriate below. Also, in each figure, reference numerals may be omitted or the same reference numerals may be used for identical or similar members or parts. Furthermore, details of the structure of the embodiments may be simplified or omitted as appropriate in the illustrations.

[0014] [About the diagnostic system] The diagnostic system 100 according to this embodiment will be described with reference to Figure 1. The diagnostic system 100 is a system for diagnosing the deterioration state of a belt 1a provided in a conveying device 1 that transports objects (for example, soil, crushed stone, and other materials related to civil engineering).

[0015] As shown in FIG. 1, the conveying device 1 includes a belt 1a on which an object (not shown) is placed, a plurality of moving rollers 1b that support the belt 1a and move it in a predetermined direction, a plurality of support rollers 1c that support the belt 1a, and a driving unit (for example, a motor, etc., not shown) that rotates the moving roller 1b.

[0016] The belt 1a is, for example, made of black rubber (for example, about 20 mm thick and about 1400 mm wide), and is formed in an endless ring shape extending in the conveying direction A2 for conveying the object. The black rubber belt 1a is difficult to reflect light, and the reflectivity of the laser light irradiated by the detection device 10 described later is, for example, lower than that of the outer peripheral surfaces of the moving roller 1b and the support roller 1c.

[0017] The moving roller 1b and the support roller 1c are formed in a cylindrical shape made of metal, are installed on the inner peripheral side of the belt 1a, and contact the inner peripheral surface of the belt 1a to support the belt 1a. When the moving roller 1b is rotated in the predetermined direction A1 by the driving unit, the belt 1a is rotated in the conveying direction A2 so as to circulate between the conveying points of the object, and the object placed on the belt 1a is conveyed. In such a conveying device 1, for example, due to contact between the object and the roller, deterioration over time, etc., the belt 1a may become dirty, worn, perforated, cracked, damaged, deteriorated, etc.

[0018] The moving roller 1b disposed at the end of the belt 1a is formed such that its width Lb is larger than the width La of the belt 1a. When the moving roller 1b is installed on the inner peripheral side of the belt 1a, both ends of the moving roller 1b protrude from the inner peripheral side in the width direction of the belt 1a. By both ends of the moving roller 1b protruding from the inner peripheral side of the belt 1a, the both ends are not covered by the belt 1a and are irradiated with the laser light output by the detection device 10 described later, and reflect the laser light.

[0019] Furthermore, the moving roller 1b is made of a material that has a higher reflectivity of the laser light emitted from the detection device 10 (described later) compared to the reflectivity of the laser light on the outer surface of the belt 1a. When the laser light is emitted from the moving roller 1b, the emitted laser light is reflected with a higher reflectivity than the outer surface of the belt 1a. As a result, when a hole, crack, or the like occurs in the belt 1a, and the outer surface of the moving roller 1b at the opening of the hole or the like is exposed to the detection device 10, the reflection of the laser light from the part of the belt 1a with the hole or the like increases compared to the part of the belt 1a without the hole or the like. Consequently, the brightness of the laser light detected by the detection device 10 (described later) increases in that part of the belt 1a compared to other parts.

[0020] In this embodiment, the moving roller 1b is formed of a material having a higher reflectivity than the reflectivity of the laser light of the belt 1a. However, it is sufficient that at least the outer surface of the moving roller 1b has a higher reflectivity than the reflectivity of the laser light of the belt 1a. For example, the outer surface of the moving roller 1b may be covered with a material having a higher reflectivity than the reflectivity of the infrared laser light of the belt 1a.

[0021] As shown in Figure 1, the diagnostic system 100 includes a detection device 10 that irradiates the belt 1a of the transport device 1 to be diagnosed with laser light Li1 and detects the reflected laser light Li2, a processing device 20 that processes and transmits the detection information detected by the detection device 10, and a diagnostic device 30 that diagnoses the deterioration state of the belt 1a based on the information transmitted from the processing device 20.

[0022] The detection device 10 is a so-called LiDAR (light detection and ranging) that measures the time from when it irradiates the object to be diagnosed with laser light Li1 (for example, infrared laser light) until the reflected laser light Li2 is detected, thereby determining the distance from the detection device 10 to the object. The detection information detected by the detection device 10 includes information about the distance from the detection device 10 to the object, calculated based on the time from when it irradiates the object with laser light Li1 until the reflected laser light Li2 is detected, and information about the brightness of the reflected laser light Li2.

[0023] The detection device 10 is positioned so as to irradiate the outer surface of the belt 1a in the portion supported by the moving roller 1b with laser light Li1. The detection device 10 may be configured such that, for example, one laser irradiator irradiates the belt 1a with laser light across its entire width (the length perpendicular to the conveying direction A2 on the belt 1a), or multiple laser irradiators may be configured to irradiate the belt 1a with laser light, each responsible for a portion of its width.

[0024] As described later, the detection device 10 acquires detection information regarding the detected laser light, including information about the distance between the detection device 10 and the belt 1a, and information about the brightness of the detected laser light Li2, and outputs this information to the processing device 20.

[0025] The processing unit 20 performs various processes from processing the detection information detected by the detection device 10 to transmitting it to the diagnostic device 30 (for example, as described later, distance information relating to the distance between a predetermined area of ​​the belt 1a and the detection device 10, brightness information relating to the brightness of the laser light in a predetermined area of ​​the belt 1a, etc. are acquired and analyzed as detection information related to the laser light detected by the detection device 10, and a leveling process is performed to generate average value information relating to the average value of the detection information, a histogram process is performed to acquire histogram information relating to the distribution of the class of the detection information by analyzing the average value information, and a transmission process is performed to output various information to the communication network 25 using wireless communication and transmit it to the diagnostic device 30 via the communication network 25).

[0026] The diagnostic device 30 is connected to the processing device 20 via a communication network 25. As described later, it stores histogram information transmitted by the processing device 20, diagnoses the deterioration state of belt 1a using the stored information and a pre-trained learning model, and provides notification according to the deterioration state of belt 1a.

[0027] As described above, the diagnostic system 100 of this embodiment is configured such that a laser beam Li1 is irradiated onto the belt 1a of the conveying device 1 as the target object, the reflected laser beam Li2 is detected by the detection device 10 and acquired as detection information, the detection information is processed by the processing device 20 and transmitted to the diagnostic device 30. Therefore, the diagnostic device 30 can acquire the detection information detected by the detection device 10 via the processing device 20 and diagnose the deterioration state of the belt 1a based on the detection information.

[0028] Furthermore, in the diagnostic system 100 of this embodiment, the detection device 10 is configured to irradiate the outer surface of the belt 1a, which is supported by a moving roller 1b made of a material having a higher reflectivity than the reflectivity of the laser light on the outer surface of the belt 1a, so when the laser light reflected by the belt 1a and the moving roller 1b is detected by the detection device 10, the brightness of the laser light reflected by the moving roller 1b can be increased compared to the brightness of the laser light reflected by the belt 1a for detection.

[0029] In the diagnostic system 100 of this embodiment, the detection device 10 is configured to irradiate the outer surface of the belt 1a supported by the moving roller 1b in the conveying device 1 with laser light. However, it is also possible to configure the system to irradiate a portion of the belt 1a other than the outer surface of the belt 1a supported by the moving roller 1b, for example, the outer surface of the belt 1a supported by the support roller 1c, or the portion of the belt 1a not supported by the moving roller 1b and the support roller 1c with laser light. In a configuration where the laser light is irradiated to the portion of the belt 1a not supported by the moving roller 1b and the support roller 1c, a reflective member having a higher reflectivity than the reflectivity of the laser light of the belt 1a is placed on the inner circumference side of the portion of the belt 1a irradiated with laser light, thereby achieving the same effect as the configuration of this embodiment.

[0030] Furthermore, although the diagnostic system 100 of this embodiment is configured to diagnose the belt 1a of the conveying device 1, the diagnostic system 100 may be configured to diagnose something other than the belt 1a. For example, it may be configured to diagnose equipment and structures related to construction and civil engineering (e.g., buildings, skyscrapers, bridge piers, etc.), and such a configuration will also produce the same effects as the configuration of this embodiment.

[0031] [About the detection device] The detection device 10 according to this embodiment will be described with reference to Figures 2 to 6. As mentioned above, the detection device 10 is a so-called LiDAR, and measures the elapsed time from when the laser beam Li1 is irradiated onto the target object (in this embodiment, the belt 1a of the transport device 1) until the reflected laser beam Li2 is detected, and calculates the distance between the detection device 10 and the target object based on the length of this elapsed time. The detection device 10 also measures the brightness of the reflected laser beam Li2.

[0032] As shown in Figure 2, the detection device 10 includes an irradiation device 11 that irradiates laser light Li1 of a predetermined wavelength (for example, a wavelength of 660 nm) toward the outside of the detection device 10, a receiving device 12 that receives the laser light Li2 reflected outside the detection device 10, and a control device 13 that controls the irradiation device 11 and the receiving device 12.

[0033] As shown in Figure 3, the irradiation device 11 of the detection device 10 includes an irradiation unit (not shown) that outputs laser light Li1 from a predetermined output position Po toward an object located outside the detection device 10 (in this embodiment, the belt 1a of the transport device 1, see Figure 1, etc.).

[0034] The irradiation device 11 controls the irradiation unit to irradiate the irradiation range B1 from the reference irradiation direction D1, which is a predetermined reference irradiation angle Θ1 from the output position Po, to the maximum irradiation direction D840, which is the maximum irradiation angle Θ2 (for example, 70°), with the laser beam Li1. The irradiation device 11 also performs trigger signal processing, which sends a trigger signal (irradiation) indicating the timing of the laser beam Li1 irradiation to the control device 13 each time the laser beam Li1 is irradiated onto the unit area sn during the irradiation process. The irradiation device 11 is controlled by the control device 13 of the detection device 10, and upon receiving instructions such as commands from the control device 13, it performs processing according to those instructions (for example, irradiation processing, trigger signal processing, etc.).

[0035] In the irradiation process, the irradiation direction of the laser beam Li1 is changed at a predetermined speed (e.g., 600 Hz) by an angle of change Δθ (e.g., 1 / 12°) from the reference irradiation angle Θ1, and the laser beam Li1 is irradiated onto the irradiation area S on the surface of the target object, belt 1a, a predetermined number of times (see Figures 3 and 4, etc.). The predetermined number of times n (e.g., 840 times) that the laser beam Li1 is irradiated onto the irradiation area S is preset based on the irradiation range Θ (e.g., 70°) and the angle of change Δθ (e.g., 1 / 12°).

[0036] Furthermore, the irradiation device 11 is positioned so as to irradiate the outer surface of the belt 1a in the portion supported by the moving roller 1b with laser light Li1. The positions of the detection device 10 and the irradiation device 11 are pre-adjusted so that the direction in which the irradiation direction of the laser light Li1 is changed by an angle θ coincides with the width direction B1 of the belt 1a (see Figure 4).

[0037] Hereinafter, the process in which the irradiation direction of the laser light Li1 is changed by an angle Δθ from the reference irradiation direction D1 to the maximum irradiation direction D840, and the laser light Li1 is irradiated a predetermined number of times, may be referred to as one scan cycle tn. In addition, the region s illuminated by the laser light Li1 during each irradiation of the predetermined number of irradiations of the laser light Li1 may be referred to as a unit region sn (in this embodiment, s1 to s840). As described above, the direction in which the irradiation direction of the laser light Li1 is changed coincides with the width direction of the belt 1a, so the unit regions sn are aligned linearly on the surface of the belt 1a from the reference irradiation direction D1 to the maximum irradiation direction D840, that is, in the width direction B1 of the belt 1a (see Figure 4, etc.). When the irradiation process is performed while the belt 1a of the conveying device 1 is moving in the conveying direction A2, the position of the irradiation area irradiated by scan cycles tn and tn+1 at two different points in time will be shifted in the conveying direction A2 of the belt 1a by at least the time difference between the two points in time and the distance traveled by the belt 1a based on the belt 1a's movement speed (see, for example, Figure 5).

[0038] The receiving device 12 includes a detection unit (not shown) that detects the laser light Li2 returning to the detection device 10. Each time the detection unit detects the laser light Li2, the receiving device 12 performs a receiving process that transmits a trigger signal (detection) indicating the timing of the detection of the laser light Li2 to the control device 13. The detection unit is also configured to acquire the brightness of the laser light Li2, and in the receiving process, the receiving device 12 acquires the brightness of the laser light Li2 detected by the detection unit and transmits brightness information related to that brightness to the control device 13.

[0039] The control device 13 is composed of a microcomputer consisting of a CPU, ROM, RAM, etc., and various programs stored in the storage device such as ROM are executed by the CPU, thereby enabling predetermined processing (for example, control processing described later). The control device 13 may be composed of dedicated hardware resources and software resources, or it may be composed of hardware resources and software resources shared with other control devices. The control device 13 also includes an acquisition unit 13a that acquires information on the trigger signal (irradiation) transmitted by the irradiation device 11, a timing unit 13b that measures the passage of time, and an execution unit 13c.

[0040] The acquisition unit 13a acquires at least state information relating to the state of a predetermined start switch (not shown), a trigger signal (irradiation) transmitted by the irradiation device 11, a trigger signal (detection) transmitted by the receiving device 12, and brightness information relating to the brightness of the laser light Li2 detected by the receiving device 12.

[0041] The timing unit 13b is equipped with a timer that measures the time elapsed from a preset reference time.

[0042] As described later, the execution unit 13c executes control processing to start controlling the irradiation device 11 and the receiving device 12 when it is determined that the start switch has been operated to the ON state based on the state information acquired by the acquisition unit 13a. Specifically, it starts control processing when the start switch is operated, causing the irradiation device 11 to repeatedly perform irradiation processing and trigger signal processing, and the receiving device 12 to repeatedly perform trigger signal processing, and also performs transmission processing to send various information in response to a request from the processing unit 20, which will be described later.

[0043] On the other hand, if it is determined that the start switch has been operated to the OFF state based on the status information, the control process is terminated, and the irradiation process in the irradiation device 11, the trigger signal processing, the reception process in the receiving device 12, and the transmission process in the control device 13 are terminated. The start switch may be provided in the detection device 10, or in one or both of the processing device 20 and the diagnostic device 30 described later. Alternatively, the start switch may be provided in a component of the diagnostic system 100 other than the detection device 10, processing device 20, and diagnostic device 30.

[0044] Next, the flow of the control processing performed by the detection device 10 will be explained based on Figure 6.

[0045] As shown in Figure 6, the control device 13 of the detection device 10 acquires state information regarding the state of the start switch (ON state or OFF state), and when it is determined that the start switch has changed from the OFF state to the ON state, it causes the execution unit 13c to start control processing (Sa). In the control processing (Sa), first, an irradiation processing command is sent to the irradiation device 11 indicating that irradiation processing and trigger signal processing will be performed (Sa1), and a reception processing command is sent to the receiving device 12 indicating that the receiving device will be executed (Sa2).

[0046] Then, upon receiving the irradiation processing command transmitted in step Sa1, the irradiation device 11 starts the irradiation processing and trigger processing (Sa3). In the irradiation processing, first, the irradiation device 11 is controlled so that the laser light Li1 is irradiated with the irradiation direction of the laser light Li1 set as the reference irradiation direction D1. Furthermore, when irradiation of the laser light Li1 in the reference irradiation direction D1 is started, a trigger signal (irradiation) is sent to the receiving device 12 and the control device 13, and an irradiation direction command indicating the irradiation direction of the laser light Li1 is sent to the control device 13. Then, after a predetermined time (for example, 12.5 milliseconds) has elapsed since the laser light Li1 was irradiated in the previous irradiation direction, the irradiation direction of the laser light Li1 is changed by an angle of change θ and updated to irradiation direction D2, and the irradiation of the laser light Li1 in the irradiation direction D2 is started. This control, and the trigger signal (irradiation) being sent again to the receiving device 12 and the control device 13 when the irradiation is started, is repeatedly executed until the irradiation direction of the laser light Li1 reaches the maximum irradiation angle Θ2.

[0047] In response, the control device 13, upon receiving the trigger signal (irradiation), acquires first time information regarding the time the trigger signal (irradiation) was transmitted based on the timer provided in the time timing unit 13b (S4). The first time information may be information about the actual time, or information about the elapsed time from a reference point.

[0048] Furthermore, upon receiving the reception processing command, the receiving device 12 initiates reception processing (S5). During reception processing, when the laser beam Li2 that has been reflected back to the detection device 10 is detected, a trigger signal (detection) indicating the timing of the detection of the laser beam Li2 is transmitted to the control device 13, and the receiving device 12 is controlled to transmit brightness information regarding the brightness of the detected laser beam Li2 to the control device 13 (S5).

[0049] In response, the control device 13, upon receiving the trigger signal (detection), acquires second time information regarding the time the trigger signal (detection) was transmitted, based on the timer provided in the time timing unit 13b (S6). The first time information and the second time information may be information about the actual time, or information about the elapsed time from a reference point.

[0050] Subsequently, the control device 13 calculates the difference between the first time information obtained in step Sa4 and the second time information obtained in step Sa6, and measures the distance between the detection device 10 and the object based on this difference (Sa7).

[0051] The control device 13 then acquires directional information regarding the irradiation direction of the laser light Li1, distance information regarding the distance measured based on the irradiation of the laser light Li1 in that direction, and brightness information regarding the brightness of the laser light Li2 detected based on the irradiation of the laser light Li1 in that direction, and transmits this information to the processing device 20 (Sa8).

[0052] Subsequently, the execution unit 13c causes the acquisition unit 13a to acquire the state information of the start switch again. If it is determined that the start switch has changed to the OFF state, the control process is terminated. However, if the start switch remains in the ON state, the control process is continued by repeatedly executing the steps Sa1 to Sa8 described above. This controls the system to repeatedly change the irradiation direction of the laser beam Li1 by an angle θ, acquire distance information, brightness information, and direction information, and transmit this information to the processing unit 20 (Sa8).

[0053] As described above, the detection device 10 repeatedly executes control processing to irradiate the belt 1a of the transport device 1 with laser light Li1 in the width direction B1, changing the angle of change θ by an amount, and detects the reflected laser light Li2 that returns. Based on the laser light Li1 and Li2, the detection device 10 measures the distance between the detection device 10 and the belt 1a for each unit area. The detection device 10 then sequentially transmits distance information related to the measured distance, direction information related to the irradiation direction of laser light Li1, and brightness information related to the brightness of the detected laser light Li2 to the processing device 20.

[0054] The control processing, irradiation processing, trigger signal processing, reception processing, and transmission processing performed by the detection device 10 are examples of processing performed by the detection device 10. The detection device 10 may also be configured to perform other processing methods different from these, to irradiate an object with laser light Li1, detect the reflected laser light Li2, measure the distance between the detection device 10 and the object based on the information regarding the laser light Li2, and measure the brightness of the reflected laser light Li2.

[0055] [About the processing unit] The processing unit 20 according to this embodiment will be described with reference to Figures 2, 7 to 9. The processing unit 20 is composed of a microcomputer consisting of a CPU, ROM, RAM, etc., and various programs stored in a storage device such as ROM are executed by the CPU, thereby enabling predetermined processing (for example, intermediate processing described later). The processing unit 20 may be composed of dedicated hardware resources and software resources, or it may be composed of hardware resources and software resources shared with other control devices (for example, the detection device 10, etc.).

[0056] As shown in Figure 2, the processing unit 20 includes an acquisition unit 20a that acquires distance information, direction information, and brightness information sequentially transmitted from the detection device 10 described above, an execution unit 20b that performs intermediate processing to generate intermediate information based on the distance information, direction information, and brightness information, and a transmission unit 20c that performs transmission processing to transmit the intermediate information to the diagnostic device 30.

[0057] As described above, the detection device 10 sequentially irradiates the laser beam Li1 with a change in angle θ within a range from the reference irradiation direction D1 to the maximum irradiation direction D840, and transmits distance information, direction information, and brightness information to the processing device 20 each time the laser beam Li1 is irradiated. In response, the acquisition unit 20a sequentially acquires the distance information, direction information, and brightness information transmitted from the detection device 10 each time the laser beam Li1 is irradiated and stores them in the storage means (e.g., RAM) of the processing device 20.

[0058] The execution unit 20b performs intermediate processing to analyze distance information, direction information, and brightness information acquired by the acquisition unit 20a, generate intermediate information, and transmit it to the diagnostic device 30. In the intermediate processing, first, a leveling process is performed in which the average value of the distance information Id and brightness information Il, which are measured in a predetermined number of scan cycles (four times in this embodiment), is acquired for each irradiation direction D1 to D840, and the acquired average value is stored in the storage means (e.g., RAM) of the processing unit 20. In the leveling process, for example, as shown in Figure 6, when the laser beam Li1 is irradiated in the irradiation direction D1, the average value of four distance pieces Id1_t1 to Id1_t4 obtained by four consecutive scan cycles t1 to t4 for a unit region s1 of the belt 1a is obtained, and leveled distance pieces Id1_t1-4 are obtained for the unit region s1' of the belt 1a that is irradiated with the laser beam Li1 as the belt 1a moves during the period in which the four scan cycles t1 to t4 are performed, and stored in the storage means (e.g., RAM) of the processing unit 20. Furthermore, for unit regions s2 to s840 corresponding to the irradiation direction D2 to D840 of the laser beam Li1, the average value of distance information Id acquired by four consecutive scan cycles is obtained, similar to unit region s1, and leveled distance information Id2_t1-4 to Id840_t1-4 is obtained for each unit region s1' to s840', and stored in the storage means (e.g., RAM) of the processing unit 20. Similarly, for luminance information Il, the average value of luminance information Il acquired by four consecutive scan cycles is obtained, for example, similar to distance information, and leveled luminance information Il is obtained for each unit region s1' to s840', and stored in the storage means (e.g., RAM) of the processing unit 20.

[0059] Then, in the intermediate processing, after the leveling process described above has been performed, the leveled distance information and leveled brightness information stored in the storage means (e.g., RAM) of the processing unit 20 are analyzed, and histogram processing is performed to generate histogram information relating to the leveled distance information and leveled brightness information for one full turn of belt 1a. In the histogram processing, first, the leveled distance information for one full turn of belt 1a stored in the storage means of the processing unit 20 by the leveling process described above is analyzed, and class information L1 to L5 is set based on each piece of leveled distance information.

[0060] The class information L1 to L5 includes information indicating the following: a first class L1 indicating that a predetermined region of belt 1a is in its initial state; a fifth class L5 indicating that a predetermined region of belt 1a is in an abnormal state; a fourth class L4 indicating that a predetermined region of belt 1a is in a state different from the initial state and the abnormal state, and is one step before becoming an abnormal state; a third class L3 indicating that it is two steps before becoming an abnormal state; and a second class L2 indicating that it is three steps before becoming an abnormal state.

[0061] The first class L1 is set when the leveled distance information is within ±1% of the average value of the distance information measured when belt 1a is in its initial state, for example; the second class L2 is set when the leveled distance information is within ±3% of the average value of the distance information measured when belt 1a is in its initial state, for example; the third class L3 is set when the leveled distance information is within ±5% of the average value of the distance information measured when belt 1a is in its initial state, for example; the fourth class L4 is set when the leveled distance information is within ±3% of the average value of the distance information measured when belt 1a is in an abnormal state, for example; and the fifth class L5 is set when the leveled distance information is within ±1% of the average value of the distance information measured when belt 1a is in an abnormal state.

[0062] Then, for example, as shown in Figure 8, the occurrence frequencies n1 to n5 of each class L1 to L5 are aggregated, and information showing the relationship between classes L1 to L5 and the occurrence frequencies n1 to n5 of each class L1 to L5, and the distribution of each class L1 to L5 is generated as histogram information. The histogram information showing the first class L1 corresponds to the first frequency information of the present invention, the histogram information showing the fifth class L5 corresponds to the second frequency information of the present invention, and the histogram information showing the second to fourth classes L2 to L4 corresponds to the third frequency information of the present invention.

[0063] Similarly to distance information, luminance information Il is also assigned classes L1 to L5 based on the leveled luminance information Il and stored in the storage means (e.g., RAM) of the processing unit 20. The occurrence frequencies n1 to n5 of each class L1 to L5 are then aggregated, and histogram information is generated showing the relationship between classes L1 to L5 and the occurrence frequencies n1 to n5 of each class L1 to L5, as well as the distribution of each class L1 to L5.

[0064] Next, the flow of the intermediate process Sb executed by the processing unit 20 will be explained based on Figure 9.

[0065] As shown in Figure 9, in the intermediate processing, distance information and brightness information transmitted from the detection device 10 are sequentially acquired, associated with direction information, and stored in the storage means of the processing device 20 (Sb01). After a predetermined number of distance information and brightness information (for example, the number of times that the belt 1a is completed) are stored in the storage means, the leveling process described above is performed, and the acquired average value is stored in the storage means of the processing device 20 (for example, RAM, etc.) (Sb02). Subsequently, the histogram processing described above is performed to set classes based on distance information and classes based on brightness information, and the occurrence frequencies n1 to n5 of each class L1 to L5 are aggregated to generate histogram information showing the distribution of each class L1 to L5 (Sb03). Then, when the wireless transmission process (Sb04) is executed, transmission information is generated based on the histogram information generated by the histogram processing in step Sb03, and this transmission information is output from the wireless communication antenna 20d and transmitted to the diagnostic device 30 by wireless communication.

[0066] As described above, the processing unit 20 repeatedly performs intermediate processing so that, for every predetermined number of data points (for example, the number of data points for one rotation of belt 1a), the distance information and brightness information are leveled, and then histogram processing is performed to set classes based on distance information and classes based on brightness information. Then, information showing the distribution of the occurrence frequency of each class is transmitted to the diagnostic device 30.

[0067] In this embodiment, the class information set in the intermediate processing performed by the processing unit 20 includes five levels of information, from the first to the fifth level L1 to L5. However, the class information only needs to include at least information indicating that a predetermined area of ​​the object is in its initial state, information indicating that a predetermined area of ​​the object is in an abnormal state, and information indicating that a predetermined area of ​​the object is in a state different from the initial state and the abnormal state. It may also include three levels of information, or six or more levels of information. Furthermore, as information indicating that a predetermined area of ​​the object is in an abnormal state, different class information may be set for each different type of abnormal state (for example, a torn belt, frayed belt, deformation, etc.). The more levels of class information that are set, the higher the accuracy of detecting signs of abnormality in the object during diagnosis by the diagnostic device 30 described later. Also, the fewer levels of class information that are set, the lower the processing load on the processing unit 20 and the load when the information is transmitted to the diagnostic device.

[0068] [About diagnostic equipment] The diagnostic device 30 according to this embodiment will be described with reference to Figure 2. The diagnostic device 30 is composed of a microcomputer consisting of a CPU, ROM, RAM, etc., and various programs stored in a storage device such as ROM are executed by the CPU, thereby enabling predetermined processing (for example, the diagnostic processing described later). The diagnostic device 30 may be composed of dedicated hardware resources and software resources, or it may be composed of hardware resources and software resources shared with other control devices.

[0069] As shown in Figure 2, the diagnostic device 30 includes an acquisition unit 30a that acquires information showing the distribution of distance information and brightness information classes 1L to 5L transmitted sequentially from the processing device 20 described above, an execution unit 30b that performs a diagnostic process to diagnose belt 1a by analyzing the distribution of distance information and brightness information classes 1L to 5L, and an output unit 30c that outputs the diagnostic results.

[0070] The diagnostic device 30 acquires information from the processing device 20 as distance information and brightness information, specifically information showing the distribution of distance information and brightness information in classes 1L to 5L, via an acquisition unit 30a. Then, it extracts the brightness information and performs a first diagnostic process to diagnose the belt 1a based on the brightness information.

[0071] In the first diagnostic process, the belt 1a is diagnosed using a first learning model that is trained using training data in which brightness information and information about the state of belt 1a are associated, and outputs the state of belt 1a as a diagnostic result in response to brightness information input. In the first diagnostic process, histogram information regarding the distribution of brightness information classes set based on the leveled brightness information for each unit region s1 to s840 obtained by the processing unit 20 performing the leveling process is input to the first learning model, and the diagnostic result of belt 1a is obtained as the output result of the model.

[0072] Furthermore, the diagnostic device 30 acquires information indicating the distribution of distance information and brightness information of classes 1L to 5L transmitted from the processing device 20 using the acquisition unit 30a, then extracts distance information, and performs a second diagnostic process to diagnose the belt 1a based on the distance information.

[0073] In the second diagnostic process, the belt 1a is diagnosed using a second learning model that is trained using training data in which distance information and information about the state of belt 1a are associated, and outputs the state of belt 1a as a diagnostic result in response to input distance information. In the second diagnostic process, histogram information regarding the distribution of distance information classes set based on the leveled distance information for each unit region s1 to s840 obtained by the leveling process performed by the aforementioned processing unit 20 is input to the second learning model, and the diagnostic result of belt 1a is obtained as the output result of the model.

[0074] The diagnostic results output by the first and second diagnostic processes are output from the output unit 30c. For example, if the diagnostic results identify that cracks or holes have occurred in the belt 1a, the location and extent of the cracks, etc., are displayed on the display device (not shown), and a warning sound is output from the audio output device (not shown) to notify the user of the transport device 1 or the diagnostic system 100. Also, for example, if the diagnostic results identify that there are signs of cracks or holes occurring in the belt 1a, this is notified via the display device and the audio output device. In addition, the diagnostic results output by the first and second diagnostic processes may be output as history information to a predetermined storage means by the output unit 30c.

[0075] [Regarding the effects and benefits 1] Conventionally, in diagnostic systems that target devices, structures, etc. related to architecture and civil engineering, which are used for relatively long periods and tend to cover a relatively large area of ​​diagnosis, the amount of information about the target object acquired for diagnosis and monitoring becomes very large, which may lead to an excessive load when transmitting this information to the diagnostic device and when processing it.

[0076] In contrast, the control method for the processing apparatus of this embodiment is a control method for a processing apparatus 20 that processes detection information (distance information relating to the distance between the detection device 10 and the belt 1a, and brightness information relating to the brightness of the detected laser light) detected by a detection device 10 that detects laser light reflected from the belt 1a of the transport device 1 as an object, and transmits it to a diagnostic device 30 that diagnoses the object using wireless communication. The processing apparatus 20 is capable of performing an acquisition step (step Sb01 in intermediate processing Sb) to acquire detection information in intermediate processing Sb, and an execution step (leveling process Sb02, histogram processing Sb03, wireless transmission processing Sb04 in intermediate processing Sb) to process and transmit the detection information. In the transmission process, the detection information acquired in the acquisition step is analyzed, and classes of detection information (distance information, brightness information) are set for each predetermined region s1 to s840 of the object, and histogram information relating to the distribution of classes (see, for example, Figure 8) is transmitted to the diagnostic device 30.

[0077] With this configuration, in the control method of the processing unit 20, the detection information (distance information and brightness information) acquired by the acquisition unit 10a is analyzed by the histogram processing Sb03 in the intermediate processing Sb, and classes L1 to L5 of the detection information are set for each predetermined area of ​​the object, and a histogram relating to the distribution of classes is acquired. The histogram information is then transmitted wirelessly to the diagnostic device 30 by the wireless transmission processing Sb04 of the intermediate processing Sb. Therefore, compared to a case where, for example, the detection information is directly transmitted to the diagnostic device 30 as is, the amount of information transmitted to the diagnostic device 30 (capacity of transmitted information) can be reduced, and the processing of analyzing the detection information and acquiring histogram information can be shared by the processing unit 20 in the histogram processing Sb03 of the intermediate processing Sb, thereby reducing the processing load on the diagnostic device 30.

[0078] In this embodiment, the diagnostic system 100 is configured to irradiate the belt 1a of the transport device 1, which is the object to be diagnosed, with laser light Li1, and detect the reflected laser light Li2 that returns with the detection device 10 to diagnose the object. In other words, the diagnostic system 100 diagnoses the object by detecting the light reflected from the belt 1a, which is the object. However, the diagnostic system 100 may also be configured to irradiate the object to be diagnosed with a predetermined sound wave (for example, ultrasound), and detect the reflected sound wave that returns with the detection device to diagnose the object. Even in a diagnostic system with such a configuration, the detection information from the detection device is analyzed to set a class of detection information for each predetermined area of ​​the object, histogram information of the detection information is acquired based on the class, and the histogram information is transmitted to the diagnostic device 30. This configuration reduces the amount of data transmitted compared to when detection information is transmitted, and the processing of analyzing the detection information and acquiring the histogram information can be shared by the processing device, thereby reducing the processing load on the diagnostic device 30.

[0079] Furthermore, in this embodiment, the diagnostic system 100 is configured to diagnose an object based on information obtained by detecting laser light reflected from the object by the detection device 10. However, the diagnostic system 100 may also be configured to diagnose an object based on image information obtained by capturing light reflected from the object by a camera. The camera may, for example, capture images in the visible light region, or capture images in the ultraviolet region, infrared region, or a combination thereof.

[0080] The control method of the processing apparatus 20 in this embodiment includes the following classes L1 to L5 set in the histogram processing Sb03 of the intermediate processing Sb: Class L1 indicates that a predetermined region (unit region s1 to s840) of the object, which is the belt 1a, is in an initial state (the initial stage of the process of transporting an object) for each detected distance information and brightness information; Class L5 indicates that a predetermined region of the object is in an abnormal state (a state in which cracks or holes have occurred); and Class L2 to L4 indicates that a predetermined region of the object is in a state different from the initial state and the abnormal state, and is in a state before it becomes abnormal (a stage before cracks or holes occur). The histogram information is configured to include frequency information (see Figure 8) relating to the occurrence frequencies n1 to n5 of each class L1 to L5.

[0081] With this configuration, multiple classes L1 to L5 are set for the detection information, indicating the stages from the initial state to the abnormal state. The histogram information includes information on the occurrence frequencies n1 to n5 of each class L1 to L5. Therefore, information on the progress of the object, belt 1a, until it reaches an abnormal state where cracks or holes occur due to deterioration, etc., can be transmitted to the diagnostic device 30.

[0082] In the control method of the processing device 20 of this embodiment, in the leveling process Sb02 of the intermediate process Sb, the average value of detection information (distance information and brightness information) over multiple scan cycles tn is obtained for each unit region s1 to s840 of the target object, belt 1a, and in the histogram process Sb03 that is executed thereafter, classes L1 to L5 are set based on the average value of the detection information (distance information and brightness information).

[0083] With this configuration, classes L1 to L5 are set based on the average value of the detection information for each unit area of ​​the target object, belt 1a. Therefore, even if the detection information detected by the detection device 10 includes detection errors, the errors based on the detection accuracy can be reduced to set classes L1 to L5.

[0084] The processing device 20 of this embodiment processes detection information detected by a detection device 10 that detects laser light reflected from the belt 1a(1) of the transport device 1, which is the object, and transmits it to a diagnostic device 30 that diagnoses the belt 1a using wireless communication. The processing device 20 comprises an acquisition unit 20a that acquires detection information, and an execution unit 20b that performs a transmission process (leveling process Sb02, histogram processing Sb03, and wireless transmission process Sb04 in the intermediate processing Sb) that processes and transmits the detection information. In the transmission process, the detection information acquired by the acquisition unit 20a is analyzed, and detection class L1 to L5 is set for each unit region s1 to s840 of the belt 1a, which is the object, and a histogram relating to the distribution of the class is acquired, and histogram information relating to this histogram is transmitted to the diagnostic device 30.

[0085] With this configuration, the processing unit performs a transmission process (intermediate processing Sb), which analyzes the detection information acquired by the acquisition unit 20a. Classes L1 to L5 of the detection information are set for each unit region s1 to s840 of the target object, belt 1a. A histogram relating to the distribution of these classes is acquired, and histogram information relating to this histogram is transmitted to the diagnostic device 30. Compared to the case where the detection information is transmitted directly to the diagnostic device 30, the amount of data (amount of information) transmitted to the diagnostic device 30 can be reduced. Furthermore, the processing unit 20 is responsible for analyzing the detection information and acquiring the histogram information, thereby reducing the processing load on the diagnostic device 30.

[0086] [Regarding the effects and benefits, part 2] Conventionally, in diagnostic systems that target devices, structures, etc. related to architecture and civil engineering, which are used for relatively long periods and tend to cover a relatively large area of ​​diagnosis, the amount of information about the target object acquired for diagnosis and monitoring becomes very large, which may lead to an excessive load when transmitting this information to the diagnostic device and when processing it.

[0087] In contrast, the control method for the processing apparatus of this embodiment is a control method for a processing apparatus 20 that processes detection information (distance information relating to the distance between the detection device 10 and the belt 1a and brightness information relating to the brightness of the detected laser light) detected by a detection device 10 that detects laser light reflected from the belt 1a of the transport device 1 as an object, and transmits it to a diagnostic device 30 that diagnoses the object using wireless communication, wherein the processing apparatus 20 includes an acquisition step (step Sb01 in intermediate processing Sb) for acquiring detection information and a transmission process (intermediate) for processing and transmitting the detection information. The system is configured to perform execution steps such as equalization processing Sb02, histogram processing Sb03, and wireless transmission processing Sb04 in the intermediate processing Sb, and in the transmission process, the detection information acquired in the acquisition step is analyzed, and average value information (equalized distance information, equalized brightness information) is acquired for each predetermined unit area s1 to s840 of the object by a predetermined number of consecutive scan cycles (for example, 4 times) of the detection information (distance information, brightness information), and predetermined information (for example, histogram information) acquired based on the average value is transmitted to the diagnostic device 30.

[0088] With this configuration, the processing unit 20 performs a transmission process, which analyzes the detection information (distance information, brightness information) acquired by the acquisition unit 20a. Average value information (leveled distance information, leveled brightness information) relating to the average value of the detection information is acquired for each predetermined area of ​​the object. Predetermined information based on the average value information (histogram information in this embodiment) is then transmitted to the diagnostic device 30. Compared to the case where the detection information is transmitted directly to the diagnostic device 30, the amount of information transmitted to the diagnostic device 30 can be reduced. Furthermore, the processing unit 20 handles the analysis of the detection information and the acquisition of average value information relating to the average value, thereby reducing the processing load on the diagnostic device 30. Moreover, by using the average value information relating to the average value of the detection information for diagnosis, detection errors in the detection information can be reduced, improving the accuracy of the diagnosis.

[0089] In the control method of the processing apparatus of this embodiment, the detection information includes distance information relating to the flight distance of the laser light reflected from the belt 1a of the conveying device 1, and brightness information relating to the brightness of the laser light reflected from the belt 1a of the conveying device 1.

[0090] With this configuration, distance information and brightness information can be used to diagnose belt 1a, thereby improving the accuracy of the diagnosis of belt 1a.

[0091] In the control method of the processing apparatus of this embodiment, during the transmission process (leveling process Sb02, histogram processing Sb03, and wireless transmission process Sb04 in the intermediate processing Sb), average value information (leveled distance information, leveled brightness information) is analyzed, and classes are set for each z-unit region s1 to s840 of the target object, belt 1a. Histogram information regarding the distribution of classes is transmitted to the diagnostic device 30, and the target object, belt 1a, is diagnosed in the diagnostic device 30 based on the histogram information.

[0092] With this configuration, in the histogram processing Sb03 of the intermediate processing Sb, the detected information (distance information, brightness information) is analyzed and detection class L1 to L5 is set for each predetermined area of ​​the target object, belt 1a. Based on these classes L1 to L5, histogram information of the detected information is acquired and transmitted to the diagnostic device 30. This configuration reduces the amount of data transmitted compared to directly transmitting the detection information detected by the detection device 10. Furthermore, since classes L1 to L5 are set based on the average value of the detection information for each area, the error based on the detection accuracy of the detected information can be reduced when setting classes L1 to L5.

[0093] The processing device 20 of this embodiment is a processing device that processes detection information (distance information and brightness information) detected by a detection device 10 that detects laser light reflected from the target object, the belt 1a, and transmits it to a diagnostic device 30 that diagnoses the target object, the belt 1a, using wireless communication. The processing device comprises an acquisition unit 20a that acquires detection information from the detection device 10, and an execution unit 20b that performs a transmission process (leveling process Sb02, histogram processing Sb03, and wireless transmission process Sb04 in intermediate processing Sb) to process and transmit the detection information. In the transmission process, the detection information acquired by the acquisition unit 20a is analyzed, and average value information regarding the average value of the detection information is acquired for each unit region s1 to s840 of the target object, the belt 1a, and histogram information is transmitted to the diagnostic device 30 as predetermined information based on the average value information.

[0094] With this configuration, the processing unit 20 performs transmission processing (leveling processing Sb02, histogram processing Sb03, and wireless transmission processing Sb04 in intermediate processing Sb), which analyzes the detection information acquired by the acquisition unit 20a. Average value information (leveled distance information, leveled brightness information) relating to the average value of the detection information is acquired for each unit region s1 to s840 of the target object, belt 1a. Histogram information is then transmitted to the diagnostic device 30 as predetermined information based on the average value information. Compared to the case where the detection information is directly transmitted to the diagnostic device 30, the amount of information (data) transmitted to the diagnostic device 30 can be reduced. Furthermore, the processing unit 20 handles the analysis of the detection information and the acquisition of average value information relating to the average value, thereby reducing the processing load on the diagnostic device 30. Moreover, by using the average value information relating to the average value of the detection information for diagnosis, the detection error of the detection information can be reduced, improving the accuracy of the diagnosis.

[0095] [Regarding the effects and benefits 3] Conventionally, there are monitoring devices for belt conveyors, which are transport devices equipped with a belt for transporting objects such as soil and sand. These devices project laser light onto the belt and receive the reflected light from the belt, measure the time difference between the timing of light projection and the timing of light reception, and monitor for the presence or absence of cracks in the belt based on the measurement results. However, in such monitoring devices, the reflected light of the laser beam reflected by the belt is used to monitor for the presence or absence of cracks. For example, if the reflectivity of the laser beam on the belt is relatively low, the reflected light will decrease, which may reduce the accuracy of crack detection.

[0096] In contrast, the diagnostic method of the diagnostic system 100 of this embodiment is a diagnostic method for diagnosing a belt 1a using the diagnostic system 100 of a conveying device 1 equipped with a belt 1a. The diagnostic system 100 comprises a detection device 10 that irradiates the belt 1a with laser light and detects the laser light reflected from the belt 1a, a moving roller 1b which is arranged on the second surface side (inner circumference side of the belt 1a) opposite to the first surface of the belt 1a irradiated with laser light and has a higher characteristic of reflecting laser light (reflectivity) compared to the belt 1a, and a diagnostic device 30 for diagnosing the belt 1a. The diagnostic system 100 is configured to perform a first acquisition step (a step in which the detection device 10 acquires brightness information) for acquiring brightness information related to the brightness of the reflected laser light, and a first diagnostic step which performs a first diagnostic process for diagnosing the belt 1a based on the brightness information.

[0097] With this configuration, the detection device 10 of the diagnostic system 100 irradiates the portion of the belt 1a supported by the reflective member (moving roller 1b) with laser light Li1, detects the reflected laser light Li2, and acquires detection information (distance information, brightness information). Therefore, when a crack or hole occurs in the belt 1a, the laser light Li1 irradiated by the detection device 10 passes through the opening of the crack or hole in the belt 1a and reaches the reflective member (moving roller 1b), and the laser light Li2 reflected by the reflective member can be detected. By having the diagnostic device diagnose the belt 1a based on the laser light Li2 which is reflected more strongly by the reflective member compared to the belt 1a, the detection accuracy of the crack or hole can be improved.

[0098] The diagnostic device 30 of this embodiment is equipped with a first learning model that is trained using training data in which brightness information and information regarding the state of belt 1a are associated, and outputs the state of belt 1a as a diagnostic result in response to brightness information input. In the first diagnostic process, belt 1a is diagnosed using the first learning model, and belt 1a is diagnosed based on the average value of brightness information acquired for each unit region s1 to s840 of the conveying device 1.

[0099] With this configuration, the diagnostic device 30 diagnoses the belt 1a using a learning model based on the average value of brightness information, thereby improving the detection accuracy of the cracks and holes detected by the diagnostic device.

[0100] In this embodiment, the diagnostic device 30 is configured such that, in the first diagnostic process, the belt 1a is diagnosed based on the brightness information class set for each unit area s1 to s840 of the transport device 1.

[0101] With this configuration, the diagnostic device 30 diagnoses belt 1a using a learning model based on the brightness information class that is pre-set and transmitted by the processing device 20, thus reducing the amount of data transmitted from the processing device 20 to the diagnostic device 30.

[0102] The diagnostic system 100 of this embodiment is configured to perform a second acquisition step (a step in which the detection device 10 acquires distance information) in which distance information relating to the flight distance of reflected laser light Li2 included in the detection information detected by the detection device 10 is acquired, and a second diagnostic step in which a second diagnostic process is performed to diagnose the belt 1a based on the distance information. The diagnostic device 30 is equipped with a second learning model that is learned using training data in which distance information and information relating to the state of belt 1a are associated, and outputs the state of belt 1a as a diagnostic result in response to input distance information. In the second diagnostic process, belt 1a is diagnosed using the second learning model.

[0103] With this configuration, the diagnostic system 100 diagnoses the belt 1a based on distance information and brightness information, thereby improving the detection accuracy of the cracks and holes detected by the diagnostic device 30.

[0104] The diagnostic device 30 of this embodiment is equipped with a second learning model that is trained using training data in which distance information and information regarding the state of belt 1a are associated, and outputs the state of belt 1a as a diagnostic result in response to input distance information. In the second diagnostic process, belt 1a is diagnosed using the second learning model, and belt 1a is diagnosed based on the average value of distance information acquired for each unit area s1 to s840 of the conveying device 1.

[0105] With this configuration, the diagnostic device 30 diagnoses the belt 1a using a learning model based on the average value of distance information, thereby improving the detection accuracy of the cracks and holes detected by the diagnostic device.

[0106] In this embodiment, the diagnostic device 30 is configured such that, in the second diagnostic process, the belt 1a is diagnosed based on the distance information class set for each unit area s1 to s840 of the transport device 1.

[0107] With this configuration, the diagnostic device 30 diagnoses belt 1a using a learning model based on the distance information class that is pre-set and transmitted by the processing device 20, thus reducing the amount of data transmitted from the processing device 20 to the diagnostic device 30.

[0108] The diagnostic system 100 of this embodiment is a system for diagnosing a belt 1a of a conveying device 1, and comprises a detection device 10 that irradiates the belt 1a with laser light Li1 and detects the laser light reflected from the belt 1a, a reflective member (moving roller 1b) which is arranged on the second surface side (inner circumference side of the belt 1a) opposite to the first surface of the belt 1a irradiated with laser light Li2 and which has a higher characteristic of reflecting laser light Li2 compared to the belt 1a, and a diagnostic device 30 which diagnoses the belt 1a based on brightness information regarding the brightness of the reflected laser light Li2 detected by the detection device 10.

[0109] With this configuration, the laser light is reflected more strongly by the support member at the openings of cracks and holes in the belt compared to other parts of the belt, thus improving the detection accuracy of the cracks and holes detected by the diagnostic device.

[0110] The reflective member of the diagnostic system 100 in this embodiment is positioned on the moving roller 1b, which is a support member that supports the belt 1a of the conveying device 1.

[0111] With this configuration, a reflective member can be positioned using a moving roller 1b that supports and moves the belt 1a, thereby improving the accuracy of detecting cracks and holes in the belt 1a.

[0112] The reflective member may be positioned on a support roller 1c, which is a support member that supports the belt 1a, or it may be positioned on a member different from the roller that supports the belt 1a and is located on the inner circumference side of the belt 1a. In these configurations, the reflective member can be positioned using the member that supports the belt 1a.

[0113] Although examples of embodiments of the present invention have been described above, it goes without saying that the present invention is not limited to these examples, and any modifications or additions that do not depart from the spirit of the present invention are also included in the present invention.
