Description

The present invention relates to an abnormality diagnosis device, a portable terminal device, an abnormality diagnosis system and a program used for diagnosing 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 an MFP (Multi Function Peripheral), which is a multi-function digital image forming apparatus, and other devices, if an abnormality such as a failure occurs, an abnormal sound is generated during operation.

Such abnormal sounds often occur periodically at a specific timing during operation, or may or may not occur due to subtle differences in operating conditions, and are sounds that measure the identification of abnormal points. It is often difficult to do it alone. For example, when the slidability of the drive unit deteriorates, a sliding noise suddenly occurs at the timing when the load on the sliding unit increases, such as when the paper is conveyed through a paper path with a high curvature or when it is pushed out during ejection. There is. It tends to occur at the same load timing, but it often does not reproduce when the state of the sliding part changes. In addition, the friction noise may be abnormal when the paper passes through an abnormal part on a specific paper passage path (for example, turning over of the paper transport guide, paper residue, wear of the Saba Kira roller), and especially the front / rear of the paper. It often occurs at the edge timing. Further, a sliding noise such as when each moving unit operates in a short time during operation such as an aftertreatment device is generated only at that timing.

Conventionally, a method has been proposed in which a sound during operation of an image forming apparatus is measured by using a mobile terminal device of a serviceman or a user, and an abnormal part where an abnormal noise is generated is identified from the measured data. (For example, Patent Document 1).

However, the technique described in Patent Document 1 described above has the following problems.

That is, the technique described in Patent Document 1 measures an abnormal sound of an image forming apparatus with a portable terminal device and determines an abnormal part by comparing it with a similar waveform of the frequency analysis result. Even if the location is known, it is not easy to actually identify it unless the timing information such as the sensor that knows the operating state of the operating part and the position of the paper is known. In the technique described in Patent Document 1, the abnormal part is specified by comparing with the waveform of the abnormal state for each factor, but the timing of the abnormal occurrence may differ or may occur depending on the conditions of the image forming apparatus. Considering that there may be no cases, there is a problem that it is difficult to sufficiently identify the abnormal part only by the waveform comparison.

It is configured in.

After an operator such as a serviceman or a user sets the conditions for image forming operation for measurement (step N01), he calls the mobile terminal 120 for measurement from the MFP 100 and requests the measurement operation (step N02). When a response is made from the mobile terminal 120 that the measurement operation is possible (step N03), the process of synchronizing the measurement proceeds. Here, the mobile terminal 120 is called when the identification information of the mobile terminal 120 registered in advance for the serviceman in the MFP 100 or the management device of the center is called, or when the measurement operation is performed and the mobile phone of the operator in the vicinity is called. There are cases where the processing proceeds with a response that the terminal 120 can handle, and cases where the operator of the MFP 100 inputs the identification information of the mobile terminal 120. If there is a response from the mobile terminal 120, the MFP 100 requests the mobile terminal 120 for model information (step N04), and based on the response (step N05), the model information is grasped. The model information includes the model information of the mobile terminal 120, the presence / absence of the installed function, the characteristics of the installed function, the characteristics of the measurement application, etc., and the necessary information is registered in advance, and the information is requested to the mobile terminal 120. By doing so, the MFP 100 is obtained and corresponds to the measurement operation.

Next, the MFP 100 requests the mobile terminal 120 to put the measurement application in the measurement standby state if it can determine that the measurement can actually be performed (step N06). Here, the request includes a start instruction of the measurement application, a download instruction and an installation instruction of the specified application from the WEB site when it is not installed, and requests the setup until the measurement is possible. ..

If the mobile terminal 120 notifies the mobile terminal 120 of the measurement standby of the measurement application (step N07), the MFP 100 notifies the mobile terminal 120 of the image formation operating condition (step N08). Specifically, it transmits information about an operating component that performs an operation to be measured, and information about an operating component that sequentially transmits an operating state during or after the operation. The information on the moving parts here is set in advance based on the information such as the image forming operation at the time of measurement and the narrowing down of some general factors, and at least the information on these moving parts is transmitted. This is to reduce the amount of transmitted data, reduce the communication load, reduce the processing load on the mobile terminal 120 side, reduce the storage area, and the like. In addition to this, the operating parts can also be specified by the operator.

The mobile terminal 120 that has received the image formation operating conditions is on standby after performing the initial settings necessary for storing those conditions, transmitting them to the management device of the center, displaying the images, and the like. Respond (step N09).

When the MFP 100 determines that the mobile terminal 120 can be measured by these series of exchanges, for example, the MFP 100 displays a message on the operation panel unit 1 to press the start button. When the operator presses the start button (step N10), the MFP 100 starts the image forming operation, and at the same time, sends synchronization information indicating the start of operation (measurement start instruction) to the mobile terminal 120 (step N11), and the mobile terminal 120 The measurement is started when the synchronization information is received, and the start of the measurement and the start of the operation of the MFP 100 are associated and synchronized. The mobile terminal 120 notifies the MFP 100 that the measurement has started (step N12).

As a result of such processing, in the mobile terminal 120, as shown in the lower diagram of FIG. 5, the start of measurement and the start of the image forming operation of the MFP 100 are synchronized, and as a result, each part of the MFP 100 is shown according to the passage of time. Even if the operation is performed as shown in the upper figure of No. 5, the measurement data and the operation of the MFP 100 can be grasped in a synchronized state and can be handled in the synchronized state. Therefore, the operator can easily identify and understand in which operating state the abnormal sound, abnormal vibration, or the like due to the failure is generated.

Although detailed explanation is omitted, there are cases where the measurement is not performed synchronously for some reason. In that case, the image formation operation is stopped, or only the image formation operation is continued and the measurement not performed is displayed. Correspondence is done.

FIG. 6 synchronizes the measurement data by the mobile terminal 120 with the image forming operation of the MFP 100 based on the start information of the image forming operation as the synchronization information transmitted from the MFP 100 to the mobile terminal 120 as described with reference to FIG. It is a flowchart for demonstrating the process of the MFP 100 in the case.

When the subroutine that performs the synchronization process is called, it is confirmed in step S130 whether or not there is a request for an image forming operation for measurement. If there is no request (NO in step S130), it returns. If there is a request (YES in step S130), in step S131, a message notifying the operator that the mobile terminal 120 is in the start standby state until the measurement standby state is displayed is displayed on the operation panel 111.

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

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

FIG. 7 shows a process of synchronizing the measurement data and the operation of the MFP 100 based on the start information of the image forming operation as the synchronization information transmitted from the MFP 100 to the mobile terminal 120 as described with reference to FIG. It is a flowchart for demonstrating the processing of a mobile terminal 120. This process is executed by the system CPU 121 of the mobile terminal 120 operating according to 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, and if not (NO in step S101), the process ends. If there is (YES in step S101), the standby notification is sent to the MFP 100 in step S102, and then it is determined in step S103 whether or not the synchronization information has been received from the MFP. If it has not been received (NO in step S103), it waits until it is received. Upon receiving (YES in step S103), after starting the measurement in step S104, the measurement start and the operation start of the MFP 100 are associated with each other and stored in the storage unit 122, and the measurement is started in step S106. Notify the MFP100.

Next, it is determined in step S107 whether or not the measurement is completed, and if it is not completed (NO in step S107), the measurement is continued in step S108, the measured value for each passage of 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 is completed.

FIG. 8 is a diagram for explaining another example of a method of synchronizing the measurement data by the mobile terminal 120 and the operation of the MFP 100. In this example, the operation start instruction information as synchronization information is transmitted from the mobile terminal 120 to the MFP 100, the MFP 100 starts the operation based on the operation start instruction information, and the mobile terminal 120 triggers the transmission of the operation start instruction information. It is configured to start measurement and synchronize the measurement data with the operation of the MFP 100.

Setting conditions for image formation operation (step N01) and requesting measurement operation (step N02). A response from the mobile terminal 120 (step N03), a request for model information from the MFP 100 to the mobile terminal 120 (step N04), an answer (step N05), and a request for a measurement standby state of the measurement application (step N06). Since the procedure up to the notification of the measurement standby of the measurement application (step N07) is the same as that of the embodiment shown in FIG. 6, the same step number is assigned and the description is omitted.

After that, the MFP 100 notifies the mobile terminal 120 of the image forming operation condition and also notifies that it is in the standby state (step N28). The mobile terminal 120 that has received the image forming operation conditions and the like responds to the MFP 100 that it has been received, and at the same time, the initial settings necessary for storing those conditions, transmitting them to the management device of the center, displaying, and the like. (Step N29). The MFP 100 displays on the operation panel 111 that its own image forming operation and the measurement by the mobile terminal 120 are started in conjunction with each other, and notifies the operator (step N30).

When the mobile terminal 120 determines that the MFP 100 is operable by these series of exchanges, it transmits the start instruction information of the image forming operation to the MFP 100 (step N31). The MFP 100 that has received the start instruction information starts the image forming operation, while the mobile terminal 120 starts the measurement with the transmission of the start instruction information as an opportunity. The MFP 100 notifies the mobile terminal 120 that the operation has started (step N32).

As a result of such processing, in the mobile terminal 120, as shown in the lower diagram of FIG. 8, the start of measurement and the start of the image forming operation of the MFP 100 are synchronized, and as a result, each part of the MFP 100 is shown according to the passage of time. Even if the operation is performed as shown in the upper figure of No. 8, the measurement data and the operation of the MFP 100 can be grasped in a synchronized state.

FIG. 9 synchronizes the measurement data by the mobile terminal 120 with the image forming operation of the MFP 100 based on the start instruction information of the image forming operation as the synchronization information transmitted from the mobile terminal 120 to the MFP 100 as described with reference to FIG. It is a flowchart for demonstrating the process of the MFP 100 in the case of making a person.

When the subroutine that performs the synchronization process is called, it is confirmed 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), it returns. If there is a request (YES in step S140), in step S141, a message notifying the operator that the image forming operation is in the standby state is displayed on the operation panel 111.

In step S142, it is confirmed whether or not the image formation operation start instruction information from the mobile terminal 120 has been received. If it has not been received (NO in step S142), it returns. If it has been received (YES in step S142), the image forming operation is started in step S143, and the mobile terminal 120 is notified that the operation is in progress. Next, in step S144, a flag indicating that the mobile terminal 120 is performing measurement in synchronization with the image forming operation is set.

FIG. 10 shows a case where the measurement data and the operation of the MFP 100 are synchronized based on the start instruction information of the image forming operation as the synchronization information transmitted from the mobile terminal 120 to the MFP 100 as described with reference to FIG. , Is a flowchart for explaining the processing of the mobile terminal 120. This process is executed by the system CPU 121 of the mobile terminal 120 operating according to 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, and if not (NO in step S111), the process ends. If there is (YES in step S111), the operation start instruction information is transmitted to the MFP 100 in step S112, then the measurement is started in step S113, and then the measurement start and the operation start of the MFP 100 are associated with each other in the storage unit in step S114. Store in 122.

Next, it is determined in step S115 whether or not the measurement is completed, and 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 is completed.

FIG. 11 is a diagram for explaining still another example of a method of synchronizing the measurement data by the mobile terminal 120 with the operation of the MFP 100. In this example, instead of synchronizing with the start of operation of the MFP 100, the information indicating the operation state of the preset operating components sent from the MFP 100 at preset time intervals from the start of operation of the MFP 100 is used as the synchronization information, and the mobile terminal is used. Each time the 120 receives synchronization information, the operation of the operating component and the measurement data are associated and synchronized.

In the example of FIG. 11, a drive motor, a paper feed clutch, a paper feed sensor, a timing clutch, a timing sensor, and the like are exemplified as preset operating parts.

Similar to the examples shown in FIGS. 5 and 8, image formation is performed after processing of exchanges such as measurement operation request / model information / application standby instruction / operation condition notification with the mobile terminal 120 before the image formation operation. At the start of operation, synchronization with the mobile terminal 120 is not performed, and after the start of image formation operation, the operation state such as the ON / OFF state of each operating component is shown from the MFP 100 to the mobile terminal 120 at predetermined time intervals Δt. The information is transmitted as synchronization information (steps N41 to N47 in FIG. 11).

On the mobile terminal 120 side, the information on the operating state received is associated with the measurement data at that time. By performing such a synchronization process every Δt, a series of measurement data can be associated with the operation state of the image forming operation, so that the synchronization is achieved. It should be noted that the association may be performed each time the synchronization information for each Δt is received, or only a part of the synchronization information is performed, and based on the synchronization state, the measurement data before that or the measurement data after that may be associated. The association with the operating state may be carried out later on the mobile terminal 120 side based on Δt. It is premised that the measurement is performed at least for a predetermined period including the image forming operation of the abnormal noise portion.

As described with reference to FIG. 11, FIG. 12 shows a data structure when the MFP 100 transmits information indicating an operating state of an operating component to the mobile terminal 120.

As described above, the ON / OFF state is converted into data at each time t0 / t1 / t2 ... For the target operating component selected in advance according to the image formation mode of the measurement target, and the MFP100 is used. The system controller 101 sequentially converts the data specified by the communication protocol into data and transmits the data to the mobile terminal 120. Depending on the operating component, it may be an analog value instead of ON / OFF, but in that case, it shall be specified by a multi-bit digital conversion value and transmitted. The data conversion method here is not limited to the sequential synchronization method shown in FIG. 11, but is synchronized at the start of the image forming operation, and information indicating the operating state of the operating component at a certain point in the image forming operation is collectively collected in chronological order. The same applies to the case of sending.

FIG. 13 shows measurement data by the mobile terminal 120 and image formation of the MFP 100 based on information indicating the operating states of a plurality of operating components as synchronization information transmitted from the MFP 100 to the mobile terminal 120 as described with reference to FIG. It is a flowchart for demonstrating the process of the MFP 100 when the operation is synchronized.

In step S150, it is checked whether or not the measurement operation by the mobile terminal 120 is in progress, and if it is not in the measurement operation (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 since the previous transmission. If it has not passed (NO in step S151), it returns. If it has passed (YES in step S151), the data for reading the operating state of the operating component selected in advance according to the measurement mode (image forming operation mode) in step S152 and transmitting it to the mobile terminal 120 in step S153. Make a set. The set data is then transmitted to the mobile terminal 120.

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

After starting the measurement in step S121, it is determined in step S122 whether or not the information indicating the operating state of the operating component is received from the MFP 100. If it has not been received (NO in step S122), it is checked whether or not the predetermined time preset in step S125 has elapsed, and if the predetermined time has not elapsed (NO in step S125), the process returns to step S122. If the predetermined time has elapsed (YES in step S125), the process ends.

If the information indicating the operating state of the operating component is received in step S122 (YES in step S122), the received information is stored in association with the measurement data in step S123, and then whether or not the measurement is completed is determined in step S124. to decide. If it is not completed (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 is terminated.

FIG. 15 is a table for explaining a method of selecting an operating component to be transmitted to the mobile terminal 120 in the example described with reference to FIG. 11.

A group of target operating parts is preset for each image forming operation mode, and when the image forming operation mode is selected by some method according to the occurrence situation of abnormal noise, the image forming operation mode is set. The corresponding group of target moving parts is extracted from the table of FIG. 15, and information about those moving parts is transmitted. The list of target operating parts may be stored in advance in the storage device 106 of the MFP 100, or may be searched from the database for failure diagnosis in the management device of the center before the image forming operation for measurement.

FIG. 16 is a diagram for explaining still another example of a method of synchronizing the measurement data by the mobile terminal 120 with the operation of the MFP 100. In this example, unlike the method of sequentially transmitting the operating state of the operating component described with reference to FIG. 11, at least one or a plurality of operating components that can be determined as a synchronization reference, such as the start information of the image forming operation, are used. By transmitting to the mobile terminal 120 an operating state that is preset for each image forming mode and can uniquely grasp changes in the operation of those operating components, it is handled as synchronization information that serves as a reference for synchronization. .. Here, by synchronizing the operation start timing of the main motor and the operation timing of the first paper feed clutch with the measurement data of the mobile terminal 120, synchronization is possible even in the subsequent time change.

Setting conditions for image formation operation (step N01) and requesting measurement operation (step N02). A response from the mobile terminal 120 (step N03), a request for model information from the MFP 100 to the mobile terminal 120 (step N04), an answer (step N05), and a request for a measurement standby state of the measurement application (step N06). Since the procedure up to the notification of the measurement standby of the measurement application (step N07) is the same as that of the embodiment shown in FIG. 5, the same step number is assigned and the description is omitted.

After that, the MFP 100 notifies the mobile terminal 120 of the image forming operation condition and also notifies that it is in the standby state (step N58). The mobile terminal 120 that has received the image forming operation conditions and the like responds to the MFP 100 that it has been received, and at the same time, it is necessary to store those conditions, transmit them to the management device 140 of the center, display the images, and the like. After performing the setting (step N59), the measurement is started.

After the measurement, as shown in the upper diagram of FIG. 16, the MFP 100 transmits the operation start timing of the main motor to the mobile terminal 120 as synchronization information when the main motor is started (step N60), and the operation timing of the first paper feed clutch. Is transmitted to the mobile terminal 120 as synchronization information (step N61).

The mobile terminal 120 associates and synchronizes the operation start timing of the received main motor, the operation timing of the first paper feed clutch, and the like within the time change of the measurement data.

By such processing, as shown in the lower figure of FIG. 16, it becomes possible to synchronize the subsequent time change of the measurement data. Since the main motor is constantly rotating during image formation, the rotation start timing and the first paper feed clutch can be used as the time reference for the image formation operation, and the time change of the subsequent measurement operation and image formation operation. Can be associated.

FIG. 17 shows an example of a method of associating the measurement data obtained by the mobile terminal 120 with the operating state of the operating component of the MFP 120.

The time (t1, t2, ... t2) is used as a parameter for the volume data value of the measurement data, the measurement level for each frequency by FFT processing, etc., and the operation state for each time of each operating component transmitted from the MFP100. And associate. By handling in this association, it is possible to easily determine the time change of the measurement data and the operating state of the MFP 100 when, for example, the measurement data and the operating state of the operating component are displayed.

FIG. 18 shows an example of handling the associated measurement data and the operating state of the operating component of the MFP 120.

In FIG. 17A, as described with reference to FIG. 17, the measurement data is stored in the storage unit 122 of the mobile terminal 120 in association with the operation state of the MFP 120, so that the measurement data is image-forming even after the measurement. It will be possible to easily determine the state of the result.

In the figure (B), the measurement data associated with the mobile terminal 120, the image forming operation mode information, and the state information of the target operating component are transmitted to the center management device 140, and the center management device 140 side performs failure analysis. Store, manage, or display as a database. The management device 140 is composed of a personal computer.

In the figure (C), the measurement data and the operating state of the operating 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 mobile terminal 120 with the operating state of the operating component of the MFP 120.

The volume data value of the measurement data, the measurement level for each frequency by FFT processing, etc., and the operation state for each time of each operating component transmitted from the MFP100 are separately referred to as "measurement result DATA_S1" and "measurement result DATA_Tm1". A series of measurements are made by handling each data group in a predetermined time unit (t1, t2, ... t2) and separately associating these data groups with the reference time (t0) that serves as a synchronization reference. Associate the data with the operating state of the operating component. In this case, based on the time (t0) of the synchronization reference described above, at the time of subsequent handling, the related processing for each time is performed again, and the handling and display processing in the management device 140 of the center are performed. good.

At the time of transmission to the management device 140 of the center, it is premised that a series of necessary related information other than the measurement data and the operation component information such as the image formation operation mode and the identification information of the target MFP 100 are also transmitted at the same time. ..

FIG. 20 shows an example of a method of displaying the measurement data obtained by the mobile terminal 120 and the operating state of the operating 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 of the screen, and the operating state of the operating parts of the MFP 100 is displayed on the same time axis by a predetermined ON / OFF display method. is 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 an abnormal noise indicated by the broken line circle, for example, it is possible to judge that it is the timing when the paper is rushing into the guide position. It can be easily determined that the noise is abnormal. The display method is an example, and depending on the screen conditions of the mobile terminal 120 and the device of the application, it is possible to display the screen in an easy-to-see screen configuration or in a state with good operability.

FIG. 21 shows another example of a method of displaying the measurement data obtained by the mobile terminal 120 and the operating state of the operating 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 touching or the like at the abnormal portion determined to be an abnormal noise indicated by the broken line circle. Since the mobile terminal 120 can determine which point in the measurement data is indicated from the coordinates of the touch input on the screen, information on the operating state of the operating component associated with the measurement data at that time can be displayed on a pop-up screen or the like. It is displayed in. As a result, the operator can determine the operating state of the moving component with an easy-to-see screen configuration, so that it can be determined, for example, that the timing is when the paper is rushing into the guide position, and it is easy to determine that the noise is abnormal at that time. can.

FIG. 22 shows an example in which, in addition to the operating state of the operating component of the MFP 100, the signal state of the image forming operation, for example, the position information of the paper and the calculation formula for calculating the operation of the mechanism unit are also handled in association with each other. ..

FIG. 22 shows a case where the calculation formula of the paper position is associated. The parameters such as the paper transport path length and the paper transport speed of the MFP 100 used in the calculation formula are preset values. The paper position can be calculated by a predetermined calculation formula from the paper size length in the image formation mode in which the measurement is performed and the operating state of each operating component (time of the ON / OFF change state, etc.), and the MFP100 They are associated and stored for each image formation mode.

Then, at the time of measurement by the mobile terminal 120, the MFP 100 transmits the set value and the calculation formula used in the calculation formula to the mobile terminal 120, and each time the information about the operating state of each operating component is transmitted from the MFP 100, the mobile terminal 120 Calculates the paper tip position using a calculation formula, and stores it in association with the measurement data and the operating state of each operating component.

From the mobile terminal 120, information indicating the operating state of the operating component and information such as a paper calculation formula are transmitted to the center management device 140, and the center management device 140 calculates the operation progress state such as the paper position. A method of returning the information to the mobile terminal 120 in association with the operating state of the operating component is also possible, and in this case, the processing load of the mobile terminal 120 can be reduced.

In the example of FIG. 22, the paper position is described, but in the MFP 100, for example, the time change of the operation of a specific mechanism unit such as the reading position of the image reading unit and the staple position of the post-processing device is calculated, and the abnormal noise location is obtained. It is possible in a similar way, such as facilitating the identification of.

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

With respect to the graph of the measurement data on the time axis, the operating state of the moving parts is shown in the graph, and the time change of the front end position and the rear end position of the paper is shown in the graph. Although not shown, layout information such as the roller position of the MFP 100 that can determine the paper position may also be displayed, and the paper position can be determined from the paper position graph. As a result, it is possible to easily determine where the front and rear edges of the paper are on the MFP 100 at the abnormal location determined to be an abnormal noise indicated by the broken line circle, which is a factor that causes the paper to rush into the guide, for example. Can be easily determined. The paper position can be displayed in an easy-to-see screen configuration or as a moving image depending on the screen conditions of the mobile terminal 120 and the device of the application.

FIG. 24 is a diagram showing an example of a method of determining and displaying a failure factor based on the relationship between the measurement data and the operating state of the operating component.

As shown in FIG. 3A, the mobile terminal 120 transmits the associated measurement data and the operating state of the operating means to the management device 140 of the center. The management device 140 side of the center is connected to a database of sound data that serves as a criterion for identifying various failure factors, and sound data for each failure factor can be extracted from those databases by searching or the like. There is. On the management device 140 side of the center, data of candidate failure factors is extracted from the database from various information such as measurement data, image formation operation mode, information of MFP100, and operation parts transmitted from the mobile terminal 120, and at the same time, data of candidate failure factors is extracted from the database. By synchronizing the sound data, which is the measurement data, with the extracted candidate data based on the time change of the operating state of the moving parts, the difference between the measurement data and the sound data in the database causes abnormal noise. The narrowing down on the time axis and the failure factor from the database are determined, and the measurement data transmitted from the mobile terminal 120 is further associated with the abnormal noise determination time and the failure factor, and the data is returned to the mobile terminal 120. As a result, on the mobile terminal 120 side, the abnormal noise data with respect to the measurement data and the factor identification can be associated with each other. In the example of FIG. 24B, the abnormal noise data at t4 and the failure factor 1 are associated with each other.

By such an association, when the measurement data and the operating state of the operating component are displayed on the display unit 124 of the mobile terminal 120, as shown in FIG. 25, abnormal noise at the abnormal portion indicated by the broken line circle in the measurement data.
