Description

  The present invention relates to an abnormality diagnosis device, a portable terminal device, an abnormality diagnosis system, and a program, which are used to diagnose an operation abnormality such as a failure of a device to be diagnosed such as an image forming device.

  In an image forming apparatus such as MFP (Multi Function Peripheral), which is a multi-function digital image forming apparatus, and other apparatuses, an abnormal sound is generated during operation when an abnormality such as a failure occurs.

  Such abnormal sounds are generated periodically at a specific timing during operation or often do not occur due to subtle differences in operating conditions. It is often difficult to do it alone. For example, when the sliding property of the drive unit or the like deteriorates, sliding noise is suddenly generated at the timing when the load on the sliding section increases, such as when the sheet is transported with high curvature of the sheet path or pushed out when discharging. There is. It is likely to occur at the same load timing, but often it will not be reproduced if the state of the sliding part is changed. In addition, the friction noise may be abnormal while passing through an abnormal portion on a specific sheet passing path (for example, the sheet transport guide is curled up, the sheet remaining, the abrasion of the separation roller). It often occurs at the end timing etc. Furthermore, a sliding noise, such as when each operating unit operates in a short time during operation, such as a post-processing device, is generated only at that timing.

  Conventionally, there has been proposed a method of measuring a sound at the time of operation of an image forming apparatus using a portable terminal device of a serviceman or a user and identifying an abnormal part where abnormal noise is generated from the measurement data. (For example, patent document 1).

  FIG. 3 is a block diagram showing an example of a control configuration of the mobile terminal device 120. As shown in FIG. Hereinafter, the portable terminal device is simply referred to as a portable terminal.

  The mobile terminal 120 may be, for example, a smart phone or a tablet terminal, and includes a system control unit 121. The storage unit 122, the communication unit 123, the display unit 124, the input unit 125, and the measurement unit 126 are connected to the system CPU 121. The system CPU 121 performs these controls. The storage unit 122 temporarily stores data in various processes such as a memory, and further stores measurement data in this embodiment.

  The communication unit 123 is a unit that performs wireless communication such as wifi or BlueTooth (registered trademark), exchanges information with the MFP 100, exchanges timing information, and also communicates with a management apparatus of a center that performs failure management and the like. . The display unit 124 is a part that displays an image such as an LCD, and displays measurement data and operation unit timing so as to be recognized by the operator.

  The input unit 125 is a touch panel on the screen, a key SW, or the like, and in the present embodiment, inputs an instruction of the operator such as instructing by touching the abnormal noise data portion of the measurement data screen.

  The measurement unit 126 is configured of a microphone that measures sound, a sound source control element, or the like, or an acceleration sensor that measures vibration.

  An example of the display screen of the measurement data in the conventional portable terminal 120 is shown in FIG. In the following description, the case where the measurement target is a sound will be described.

  The time change of measurement data is displayed as a graph on the screen to make it easy for the operator to see. As the display method, there are various different display methods depending on the screen or application of the portable terminal 120, but in the present embodiment, any display can be used as long as the time change of the sound to be measured can be understood. It is good. Further, although in FIG. 5 the data is the total sound volume, the same may be applied to the time change for each frequency due to the FFT processing or the time change such as the vibration amount such as vibration or the vibration frequency. In FIG. 5, since only the time change is displayed, the operation state of the image forming operation of MFP 100 is not displayed up to which volume the operation state is. Therefore, the operator moves MFP 100 and the time There is no choice but to compare the measured data to judge the operation, and not enough to identify the cause of noise.

  Therefore, in order to solve this problem, in this embodiment, the portable terminal 120 temporally synchronizes the measurement data and the operation of the MFP 100 using synchronization information indicating a predetermined operation state of the MFP 100.

  FIG. 5 is a diagram for describing an example of a method of synchronizing measurement data by portable terminal 120 with the operation of MFP 100. In this example, synchronization information indicating the start of the image forming operation is transmitted from MFP 100 to portable terminal 120, and measurement is started when portable information 120 is received as synchronization information to synchronize the measurement data with the operation of MFP 100. Is configured.

  After an operator such as a serviceperson or a user sets conditions for the image forming operation for measurement (step N01), the MFP 100 calls the portable terminal 120 to perform measurement and requests the measurement operation (step N02). When the portable terminal 120 responds that the measurement operation is possible (step N03), the process of synchronizing the measurement is advanced. Here, the mobile terminal 120 is called when calling the identification information of the mobile terminal 120 registered in advance for service personnel in the management apparatus of the MFP 100 or the center, or the mobile terminal of the operator who is in the vicinity of calling measurement operation. There may be a case where the process proceeds with a response that can be handled by the terminal 120, or a case where the operator of the MFP 100 inputs identification information of the portable terminal 120. If there is a response from the portable terminal 120, the MFP 100 requests model information from the portable terminal 120 (step N04), and from the reply (step N05), the model information is grasped. The model information includes model information of the mobile terminal 120, presence / absence of the mounted function, characteristics of the mounted function, characteristics of the measurement application, etc., necessary information is registered in advance, and these are requested to the mobile terminal 120 By doing this, the MFP 100 obtains it and copes with the measurement operation.

  Next, if it is determined that the measurement can be actually performed, the MFP 100 requests the portable terminal 120 to put the measurement application in the measurement standby state (step N06). Here, the request includes the start instruction of the measurement application, the download instruction and the installation instruction of the specified application from the WEB site in the case of not being installed, etc., and the request for setup until the measurement is possible is made. .

  If there is a notification of measurement standby of the measurement application from the portable terminal 120 (step N07), the MFP 100 notifies the portable terminal 120 of the image forming operation condition (step N08). Specifically, information on an operating part that performs an operation to be measured and information on an operating part that transmits an operating state sequentially during or after an operation are transmitted. The information of the moving parts here is preset based on the information such as the image forming operation at the time of measurement and narrowing down of the rough factor to some extent, and the information of these moving parts is transmitted at least. This is for reducing the amount of transmission data, reducing the communication load, reducing the processing load on the portable terminal 120 side, and reducing the storage area. In addition to this, it is also possible for the operator to specify the moving parts.

  The portable terminal 120 having received the image forming operation conditions performs the initial setting necessary for storing the conditions, transmitting them to the management apparatus of the center, or performing display etc. Respond (step N09).

  If the MFP 100 determines that the portable terminal 120 can be measured by the series of exchanges, the MFP 100 displays a message on the operation panel unit 1 to press the start button, for example. When the operator presses the start button (step N10), the MFP 100 starts an image forming operation and transmits synchronization information indicating an operation start (measurement start instruction) to the portable terminal 120 (step N11). The measurement is started in response to the reception of the synchronization information, and the start of the measurement and the operation start of the MFP 100 are associated and synchronized. The portable terminal 120 notifies the MFP 100 that measurement has been started (step N12).

  As a result of the start of measurement and the start of the image forming operation of MFP 100 being synchronized in portable terminal 120 by such processing as shown in the lower diagram of FIG. Even when the operation shown in the upper diagram of 5 is performed, the measurement data and the operation of the MFP 100 can be grasped in a synchronized state, and can be handled in a synchronized state. Therefore, the operator can easily identify and grasp in which operation state an abnormal sound or an abnormal vibration or the like due to a failure occurs.

  Although detailed description is omitted, measurement may not be performed synchronously due to some reason, in which case, various operations may be performed such as stopping the image forming operation or continuing only the image forming operation and displaying measurement not performed. A response is made.

FIG. 10 is a flowchart for describing processing of the MFP 100 in the case.

  When the subroutine for performing synchronous processing is called, in step S130, the presence or absence of a request for an image forming operation for measurement is confirmed. If there is no request (NO in step S130), the process returns. If there is a request (YES in step S130), in step S131, a message is displayed on the operation panel 111 to notify the operator that the mobile terminal 120 is in the start standby state until it is in the measurement standby state.

  In step S132, it is confirmed whether or not the measurement start instruction is awaited, and if the measurement start instruction is not awaited (NO in step S132), the process returns. If the measurement start instruction is awaited (YES in step S132), in step S133, the standby release and the operation enablement of the image forming operation are displayed, and the process waits for a start. In step S134, it is determined whether the start button of the image forming operation is pressed (whether or not the start input is on), and if not pressed (NO in step S134), the process returns. When the button is pressed (YES in step S134), the image forming operation is started in step S135, and the mobile terminal 120 is instructed to start measurement.

  Next, in step S136, it is checked whether or not measurement has been performed in synchronization with the portable terminal 120. If it has been performed (YES in step S136), a flag of the image forming operation state is set in step S137. If not implemented (NO in step S136), a flag of measurement synchronization failure is set in step S138.

  FIG. 7 shows a process of synchronizing measurement data with the operation of MFP 100 based on start information of the image forming operation as synchronization information transmitted from MFP 100 to portable terminal 120 as described with reference to FIG. 5 is a flowchart for explaining processing of the mobile terminal 120. This process is executed by the system CPU 121 of the portable terminal 120 operating in accordance with the operation program stored in the storage unit 122 or the like.

  In step S101, it is checked whether or not there is a standby instruction from the MFP 100. If not (NO in step S101), the process ends. If there is (YES in step S101), in step S102, a standby notification is sent to the MFP 100, and in step S103, it is determined whether synchronization information has been received from the MFP. If not received (NO in step S103), the process waits until received. If received (YES in step S103), measurement is started in step S104, and in step S105, measurement start and operation start of MFP 100 are associated and stored in storage unit 122, and in step S106, measurement is started The MFP 100 is notified.

  Next, in step S107, it is determined whether or not the measurement is completed. If it is not completed (NO in step S107), the measurement is continued in step S108 and the measured value for each elapsed time is stored in the storage unit 122, and then step S107. Return to When the measurement is completed (YES in step S107), the process ends.

  FIG. 8 is a diagram for explaining another example of a method of synchronizing measurement data by portable terminal 120 with the operation of MFP 100. Referring to FIG. In this example, operation start instruction information as synchronization information is transmitted from portable terminal 120 to MFP 100, and based on the operation start instruction information, MFP 100 starts operation, and portable terminal 120 is triggered by transmission of operation start instruction information. The measurement is started, and the measurement data and the operation of the MFP 100 are synchronized.

  Condition setting of image forming operation (step N01), request of measurement operation (step N02). A response from the portable terminal 120 (step N03), a request for model information from the MFP 100 to the portable terminal 120 (step N04), an answer thereto (step N05), and a request for measurement standby state of the measurement application (step N06). The steps up to the notification (step N07) of the measurement standby of the measurement application are the same as those in the embodiment shown in FIG.

  Thereafter, the MFP 100 notifies the image forming operation condition to the portable terminal 120, and notifies itself that it is in the standby state (step N28). The portable terminal 120 having received the image forming operation conditions and the like responds to the received information to the MFP 100, stores the conditions, transmits them to the management apparatus of the center, or performs initial setting necessary for displaying etc. (Step N29). The MFP 100 displays on the operation panel 111 that the image forming operation of its own and the measurement by the portable terminal 120 are interlocked and started, and notifies the operator (step N30).

  If the portable terminal 120 determines that the MFP 100 is operable by the series of exchanges, it transmits start instruction information of the image forming operation to the MFP 100 (step N31). The MFP 100 having received the start instruction information starts an image forming operation, while the portable terminal 120 starts measurement in response to the transmission of the start instruction information. The MFP 100 notifies the portable terminal 120 that the operation has been started (step N32).

  As a result of the start of measurement and the start of the image forming operation of MFP 100 being synchronized as shown in the lower diagram of FIG. Even when the operation shown in the upper side of FIG. 8 is performed, the measurement data and the operation of the MFP 100 can be grasped in a synchronized state.

  FIG. 9 synchronizes the measurement data of the portable terminal 120 with the image forming operation of the MFP 100 based on start instruction information of the image forming operation as synchronization information transmitted from the portable terminal 120 to the MFP 100 as described in FIG. FIG. 10 is a flowchart for explaining the processing of the MFP 100 in the case of making

  When the subroutine for performing synchronous processing is called, it is checked in step S140 whether or not there is a request for an image forming operation for measurement. If there is no request (NO in step S140), the process returns. If there is a request (YES in step S140), a message is displayed on operation panel 111 to notify the operator that the image forming operation is in a standby state in step S141.

  In step S142, it is checked whether start instruction information of the image forming operation from the portable terminal 120 has been received. If not received (NO in step S142), the process returns. If it is received (YES in step S142), the image forming operation is started in step S143, and the portable terminal 120 is notified that it is in operation. Next, in step S144, a flag indicating that measurement is being performed in synchronization with the image forming operation is set.

  FIG. 10 shows a case where processing of synchronizing measurement data and the operation of MFP 100 is performed based on start instruction information of an image forming operation as synchronization information transmitted from portable terminal 120 as described in FIG. 9 is a flowchart for explaining the processing of the mobile terminal 120. This process is executed by the system CPU 121 of the portable terminal 120 operating in accordance with the operation program stored in the storage unit 122 or the like.

  In step S111, it is checked whether there is a standby notification from the MFP 100. If there is no notification (NO in step S111), the process ends. If there is (YES in step S111), operation start instruction information is transmitted to MFP 100 in step S112, and then measurement is started in step S113. Then, in step S114, the memory start is associated with operation start of MFP 100. It stores in 122.

  Next, in step S115, it is determined whether or not the measurement is completed. If it is not completed (NO in step S115), the measurement is continued in step S116, and then the process returns to step S115. When the measurement is completed (YES in step S115), the process ends.

  FIG. 11 is a diagram for illustrating yet another example of a method of synchronizing measurement data by portable terminal 120 with the operation of MFP 100. In this example, instead of synchronizing with the operation start of the MFP 100, the information indicating the operation state of the preset operation components sent from the MFP 100 every predetermined time from the operation start of the MFP 100 is used as the synchronization information. Each time the synchronization information is received, the operation of the operating part and measurement data are associated and synchronized.

  In the example of FIG. 11, a drive motor, a sheet feeding clutch, a sheet feeding sensor, a timing clutch, a timing sensor, and the like are illustrated as preset operation parts.

  As in the example shown in FIGS. 5 and 8, after processing of exchange of measurement operation request / model information / application standby instruction / operation condition notification etc. with the portable terminal 120 before image formation operation, image formation is performed. At the start of operation, synchronization with portable terminal 120 is not performed, and after the start of the image forming operation, MFP 100 to portable terminal 120 indicates an operation state such as ON / OFF state of each operation component at predetermined time intervals Δt set in advance. The information is transmitted as synchronization information (steps N41 to N47 in FIG. 11).

  On the side of the portable terminal 120, the information of the received operation state is associated with the measurement data at that time. By performing such synchronization processing at every Δt, since a series of measurement data can be associated with the operation state of the image forming operation, synchronization is established. The association may be performed each time the synchronization information for each Δt is received, or only a part is performed, and based on the synchronization state, measurement data before that or measurement data after that is used. The association with the operation state may be performed later on the portable terminal 120 side on the basis of Δt. It is assumed that measurement is performed at least for a predetermined period including an image forming operation of the abnormal sound portion.

  As described in FIG. 11, FIG. 12 shows a data configuration in the case where the MFP 100 transmits information indicating the operation state of the operation component to the portable terminal 120.

  As described above, the ON / OFF state is digitized at each time t0 / t1 / t2... With respect to the target moving parts selected in advance according to the image forming mode to be measured, and MFP 100 The system controller 101 sequentially converts the data defined by the communication protocol and transmits the data to the portable terminal 120. Note that depending on the operating part, it may be an analog value or the like instead of ON / OFF, but in this case, it is defined by digital conversion values of a plurality of bits and transmitted. The data conversion method here is not only the sequential synchronization method shown in FIG. 11 but also synchronizes at the start of the image forming operation, and collectively collects information indicating the operating state of the operating parts at a certain point in the image forming operation. The same applies to the case of sending a message.

  FIG. 13 shows measurement data by the portable terminal 120 and image formation of the MFP 100 based on the information indicating the operating state of a plurality of operating components as synchronization information transmitted from the MFP 100 to the portable terminal 120 as described in FIG. FIG. 10 is a flowchart for describing processing of the MFP 100 when synchronizing operations. FIG.

  In step S150, it is checked whether or not the measurement operation by the portable terminal 120 is in progress, and if the measurement operation is not in progress (NO in step S150), the process returns. If the measurement operation is in progress (YES in step S150), it is determined in step S151 whether or not a predetermined time Δt has elapsed from the previous transmission. If it has not elapsed (NO in step S151), the process returns. If it has elapsed (YES in step S151), in step S152, the operation state of the operation component selected in advance according to the measurement mode (image forming operation mode) is read, and in step S153, data for transmitting to the portable terminal 120 Do the set. The set data is then transmitted to the mobile terminal 120.

  FIG. 14 shows measurement data by the portable terminal 120 and image formation of the MFP 100 based on the information indicating the operating state of a plurality of operating components as synchronization information transmitted from the MFP 100 to the portable terminal 120 as described in FIG. It is a flowchart for demonstrating the process of the portable terminal 120 in the case of synchronizing operation | movement. This process is executed by the system CPU 121 of the portable terminal 120 operating in accordance with the operation program stored in the storage unit 122 or the like.

  After measurement is started in step S121, it is determined in step S122 whether or not information indicating the operation state of the operation component is received from the MFP 100. If it has not been received (NO in step S122), it is checked whether a predetermined time set in advance has passed in step S125. If the predetermined time has not passed (NO in step S125), the process returns to step S122. If the predetermined time has elapsed (YES in step S125), the process ends.

  If it is determined in step S122 that the information indicating the operation state of the moving part has been received (YES in step S122), the received information is stored in association with the measurement data in step S123, and then in step S124 to decide. If it is not the end (NO in step S124), the measurement is continued in step S125, and then the process returns to step S122. When the measurement is completed (YES in step S124), the process ends.

  FIG. 15 is a table for describing a method of selecting an operation component to be transmitted to the portable terminal 120 in the example described with reference to FIG.

  When a group of operating parts to be processed is set in advance for each image forming operation mode, and the image forming operation mode is selected by any method according to the occurrence of abnormal noise, the image forming operation mode is selected. The group of the corresponding target motion parts is extracted from the table of FIG. 15 and information is transmitted for the motion parts. The list of operating parts to be targets may be stored in advance in the storage device 106 of the MFP 100, or may be searched from a failure diagnosis database in the management apparatus of the center before the image forming operation for performing measurement.

  FIG. 16 is a diagram for illustrating yet another example of a method of synchronizing measurement data by portable terminal 120 with the operation of MFP 100. In this example, unlike the method of sequentially transmitting the operation state of the operation parts described in FIG. 11 every constant time, at least one or more of the operation parts that can be determined as the synchronization reference like the start information of the image forming operation The image forming mode is set in advance, and is handled as synchronization information as a reference of synchronization by transmitting to the portable terminal 120 an operation state capable of uniquely grasping the change in the operation of the operation parts thereof. . Here, by synchronizing the operation start timing of the main motor and the operation timing of the first sheet feeding clutch with the measurement data of the portable terminal 120, synchronization is enabled even in the subsequent time change.

  Condition setting of image forming operation (step N01), request of measurement operation (step N02). A response from the portable terminal 120 (step N03), a request for model information from the MFP 100 to the portable terminal 120 (step N04), an answer thereto (step N05), and a request for measurement standby state of the measurement application (step N06). The steps up to the notification (step N07) of the measurement standby of the measurement application are the same as those in the embodiment shown in FIG.

  Thereafter, MFP 100 notifies image forming operation condition to portable terminal 120, and notifies itself that it is in a standby state (step N58). The portable terminal 120 having received the image forming operation conditions and the like responds to the received information to the MFP 100, stores the conditions, transmits it to the management apparatus 140 of the center, or performs initial display etc. After setting (step N59), measurement is started.

  After the measurement, as shown in the upper side of FIG. 16, when the main motor is activated, the MFP 100 transmits the operation start timing of the main motor as synchronization information to the portable terminal 120 (step N60), and the operation timing of the first sheet feeding clutch. Are transmitted to the portable terminal 120 as synchronization information (step N61).

  The portable terminal 120 synchronizes the received operation start timing of the main motor, the first operation timing of the sheet feeding clutch, and the like in the time change of the measurement data.

  By such processing, as shown in the lower diagram of FIG. 16, synchronization of the subsequent time change of the measurement data becomes possible. Since the main motor is always rotating during image formation, the rotation start timing and the first sheet feeding clutch can be used as the time reference of the image forming operation, and the time change of the subsequent measurement operation and the image forming operation It becomes possible to associate

  FIG. 17 illustrates an example of a method of associating measurement data obtained by the portable terminal 120 with the operation state of the operation component of the MFP 120.

  The time (t 1, t 2,... T 2) is used as a parameter for the volume data value of measurement data, the measurement level for each frequency by FFT processing, etc., and the operation state for each operation component transmitted from MFP 100. To associate. By associating and handling in this manner, it is possible to easily determine the time change of the measurement data and the operation state of the MFP 100 when, for example, the measurement data and the operation state of the operation component are displayed.

  FIG. 18 illustrates an example of handling of the measurement data associated with each other and the operation state of the operation component of the MFP 120.

  In (A) of the figure, as described with reference to FIG. 17, the measurement data and the operation state on the MFP 120 side are associated with each other and stored in the storage unit 122 of the portable terminal 120. It will be easy to determine what kind of condition the result is.

  In the same figure (B), measurement data associated with the portable terminal 120, image forming operation mode information, and information on the state of the target moving parts are transmitted to the management apparatus 140 of the center, and failure analysis or Store or display as a database. The management device 140 is configured by a personal computer.

  In FIG. 7C, the measurement data and the operation state of the operation component are displayed in association with each other on the screen of the display unit 124 of the mobile terminal 120.

  FIG. 19 shows another example of the method of associating the measurement data obtained by the portable terminal 120 with the operation state of the operation component of the MFP 120. As shown in FIG.

  The measurement data volume level of measurement data, the measurement level for each frequency by FFT processing, etc., and the operation status for each operation part of each operation component transmitted from MFP 100 are separately "measurement result DATA_S1" and "measurement result DATA_Tm1". A series of measurements are handled by treating the data groups as predetermined time units (t1, t2, ... t2) and associating the data groups with a reference time (t0) as a synchronization reference separately Associate the data with the operating status of the operating part. In this case, based on the time (t0) of the above-mentioned synchronization standard, at the time of subsequent handling, processing of associating with each time is performed again, and processing and display in the management apparatus 140 of the center may be performed. good.

  In addition, it is assumed that at the time of transmission to the management apparatus 140 of the center, a series of related information other than measurement data and operation parts information, such as an image forming operation mode and identification information of the target MFP 100, are simultaneously transmitted. .

  FIG. 20 shows an example of a method of displaying the measurement data obtained by the portable terminal 120 and the operation state of the operation component of the MFP 120 according to the time change.

  In FIG. 20, the time change of sound which is measurement data is displayed as a graph at the upper part in the screen, and the operation state of the moving parts of MFP 100 is displayed on the same time axis by the predetermined ON / OFF display method. doing. By displaying in this way, it is possible to judge from the state of the moving parts at the abnormal part judged to be abnormal noise shown by the broken line circle, for example, it is judged that it is the timing when the sheet rushes into the guide position It can be easily determined that the noise is unusual. Note that the display method is an example, and the screen conditions of the portable terminal 120, the device of the application, and the like enable display with an easy-to-see screen configuration and display with good operability.

  FIG. 21 shows another example of the method of displaying the measurement data obtained by the portable terminal 120 and the operation state of the operation component of the MFP 120 according to the time change.

  In FIG. 21, only the time change of the measurement data is displayed, and the screen portion is instructed by touch or the like at an abnormal place determined to be abnormal noise indicated by a broken line circle. The portable terminal 120 can determine from the coordinates of the touch input on the screen what time point of the measurement data is indicated, so information on the operation state of the moving part associated with the measurement data at that time is displayed as a pop-up screen etc. It is displayed by. As a result, the operator can determine the operation state of the moving parts with an easy-to-see screen configuration, so that it can determine, for example, that it is the timing when the sheet rushes into the guide position, etc. it can.

  FIG. 22 shows the case where the sheet position calculation formula is associated. The parameters, such as the sheet conveyance path length of the MFP 100 and the sheet conveyance speed, used in the calculation formula are setting values set in advance. The sheet position can be calculated by a predetermined calculation formula from the sheet size length in the image forming mode in which the measurement is performed and the operation state of each operation part (time of change state of ON / OFF, etc.) They are stored in association with each image forming mode.

  Then, at the time of measurement by the portable terminal 120, the MFP 100 transmits the setting value and calculation formula used for the calculation formula to the portable terminal 120, and the information regarding the operation state of each operation component is transmitted from the MFP 100. The sheet front end position is calculated using a calculation formula, and is stored in association with the measurement data and the operation state of each operation component.

  Note that information indicating the operation state of the moving part and information such as a sheet calculation formula are transmitted from the portable terminal 120 to the management device 140 of the center, and the management device 140 of the center calculates the operation progress state such as the sheet position, A method of returning to the mobile terminal 120 in association with the operation state of the operating part or the like is also possible. In this case, the processing load of the mobile terminal 120 can be reduced.

  Although the paper position is described in the example of FIG. 22, in MFP 100, for example, the time change of the operation of a specific mechanical unit such as the reading position of the image reading unit or the stapling position of the post-processing device is calculated It is possible in a similar manner, such as to facilitate identification of

  FIG. 23 illustrates an example of a method of displaying the sheet position information and the operation state of the mechanical unit in addition to the measurement data and the operation state of the operation component of the MFP 100.

Although not shown, layout information such as the roller position of MFP 100 that can determine the sheet position may be displayed, and the sheet position can be determined from the graph of the sheet position. As a result, it is possible to easily determine at which position on the MFP 100 the leading end and the trailing end of the sheet are at an abnormal point determined to be abnormal noise indicated by a broken line circle, which is a factor that the sheet rushes into the guide, for example. Can easily judge. Note that the display method of the sheet position can also be displayed in an easy-to-see screen configuration or in a moving image or the like by the screen conditions of the mobile terminal 120, the device of the application, or the like.

  FIG. 24 is a diagram showing an example of a method of determining and displaying a cause of failure based on the association between measurement data and the operating state of an operating part.

  As shown in FIG. 6A, the portable terminal 120 transmits the associated measurement data and the operating state of the operating means to the management device 140 of the center.

As a result, the abnormal sound data for the measurement data and the factor identification thereof can be associated on the portable terminal 120 side. In the example of FIG. 24B, the abnormal noise data at t4 and the failure factor 1 are associated.
