Description

[Technical Field]

[0001] The present invention relates to an information processing device and a program. [Background technology]

[0002] For example, one method for detecting abnormalities in devices such as multifunction peripherals is to use a sound collection device such as a microphone. Specifically, a sound collection device is attached to the inside of the device, and the sound is collected and analyzed to detect abnormalities. By determining the installation position of the sound collection device in advance, it is also possible to identify the location of the abnormality.

[0003] However, if customers use the equipment with the sound collection means attached, there is a risk of eavesdropping, which makes it difficult for customers to accept. For this reason, the sound collection means is sometimes made detachable so that it can be attached only when necessary. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-133885 [Patent Document 2] Japanese Patent Application Laid-Open No. 2015-094620 Summary of the Invention [Problem to be solved by the invention]

[0005] Suppose an abnormality in the device is detected by analyzing the sound picked up by the sound pickup means. In this case, it is possible that the problem is not actually the device itself, but that the detachable sound pickup means is not properly attached to the designated position. In other words, improper attachment of the sound pickup means may result in normal sounds being mistaken for abnormal sounds. Therefore, it is preferable to be able to diagnose whether the sound pickup means is properly attached even before the device is first used.

[0006] The present invention aims to diagnose a sound collection means used to identify an abnormality from the operating sound of a device by testing the device after the sound collection means is attached to the device and before the device is put into operation. [Means for solving the problem]

[0007] The information processing device of the present invention is equipped with a processor, and in a test mode of a sound collection means used to identify an abnormal part of an equipment from the operating sound of the equipment, after the sound collection means is attached to the equipment and before the equipment is operated, the processor operates a specified component included in the equipment, acquires signal data output from the sound collection means when the specified component is operating, and if the signal data does not match predetermined reference data that is output from the sound collection means when the sound collection means is correctly fixed in a specified position of the equipment, displays a diagnostic result indicating that the sound collection means is malfunctioning.

[0008] The processor may also display instructions for resolving the malfunction of the sound pickup means as a diagnostic result of the malfunction.

[0009] Furthermore, when the sound pressure of the sound picked up by the sound pickup means obtained from the signal data does not match the reference data regarding sound pressure, the processor displays an instruction to properly attach the sound pickup means to the specified position as a diagnostic result of the malfunction.

[0010] Furthermore, if the sound pressure of the sound picked up by the sound pickup means obtained from the signal data does not match the reference data regarding sound pressure, and if the frequency of the sound picked up by the sound pickup means obtained from the signal data does not match the reference data regarding frequency, the processor displays an instruction to replace the sound pickup means as a diagnostic result of the malfunction.

[0011] The processor is also characterized in that if the sound pressure and frequency of the sound picked up by the sound pick-up means obtained from the signal data do not match the reference data even after the sound pick-up means has been replaced, it displays a message indicating that there is an abnormality in the specified part.

[0012] Furthermore, when the frequency of the sound collected by the sound collection means obtained from the signal data does not match the reference data, the processor displays an instruction to fix the attachment jig for the sound collection means to the equipment as a diagnostic result of the malfunction.

[0013] The program of the present invention enables a computer to realize the following functions: when in test mode for a sound collection means used to identify abnormal parts of equipment from the operating sounds of the equipment, after the sound collection means is attached to the equipment and before the equipment is operated, operate a specified component included in the equipment; acquire signal data output from the sound collection means when the specified component is operating; and, if the signal data does not match preset reference data output from the sound collection means when the sound collection means is correctly fixed in a specified position on the equipment, display a diagnostic result indicating that the sound collection means is malfunctioning. [Effects of the Invention]

[0014] According to the invention described in claim 1, the sound collection means used to identify abnormalities from the operating sounds of equipment can be diagnosed in a test before the equipment is put into operation after the sound collection means is attached to the equipment.

[0015] According to the invention as set forth in claim 2, it is possible to perform an operation to eliminate malfunction of the sound collection means.

[0022] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

[0023] 1 is a diagram showing an example of the hardware configuration of a multifunction peripheral according to the present embodiment. In this embodiment, a multifunction peripheral equipped with a plurality of functions will be described as an example of a device.

[0024] The multifunction peripheral 10 is an image forming device equipped with various functions, such as printing, copying, and scanning, and includes a built-in computer, which is an information processing device. In FIG. 1, ROM 12 stores various programs related to the control of the device, encryption of electronic data, and transmission and reception of electronic data. A CPU 11 controls the operation of various mechanisms installed in the device, such as a scanner 16 and a printer 17, in accordance with the programs stored in ROM 12. RAM 13 is used as a work memory for programs to be executed and for program execution. A hard disk drive (HDD) 14 stores electronic documents scanned using the scanner 16. An operation panel 15 accepts instructions from the user and displays information. The scanner 16 scans documents placed by the user and stores the scanned data in the HDD 14. The printer 17 prints images on output paper in accordance with instructions from the control program executed by the CPU 11. A network interface (IF) 18 connects to a network and is used for data exchange with external devices and accessing the device via a browser. An input / output interface (IF) 19 is used to connect an input device or an output device, and an address data bus 20 connects to various mechanisms controlled by the CPU 11 to communicate data.

[0025] In this embodiment, a sensor 21 is connected to the input / output interface 19. The sensor 21 is a sound collection means for collecting sound, and in this embodiment, a microphone is used as the sound collection means. The connection relationship between the input / output interface 19 and the sensor 21 will be described later. The sensor 21 converts sound into an electrical signal. The converted data is input to the multifunction device 10 via the input / output interface 19 and analyzed when diagnosing the sensor 21.

[0026] 2 is a diagram showing an example of a block configuration of the multifunction device 10 according to the present embodiment. The multifunction device 10 has a control unit 31, a test execution unit 32, an operation control unit 33, a data receiving unit 34, a display control unit 35, and a storage unit 36. Note that components not used in the description of the present embodiment are omitted from the diagram.

[0027] The control unit 31 cooperates with other components to control the entire multifunction device 10. The function of the test execution unit 32 is fulfilled by a test program that starts execution when a test mode is selected. The test execution unit 32 diagnoses the sensor 21 by executing a diagnostic test. The operation control unit 33 controls the operation of a predetermined part mounted on the multifunction device 10. For example, in this embodiment, the motor operated in the test corresponds to the predetermined part. The data receiving unit 34 receives signal data (hereinafter referred to as "sensor data") output from the sensor 21. The display control unit 35 controls the display on the operation panel 15.

[0028] In this embodiment, in the test mode, a diagnosis is made to determine whether the sensor 21 operates correctly. For the sensor 21 to operate correctly, it must be properly secured in a predetermined position on the multifunction device 10. Therefore, in the test mode, a diagnosis is made to verify this. To this end, signal data output from the sensor 21 when the sensor 21 is properly secured in a predetermined position on the multifunction device 10 is prepared in advance as reference data. In this embodiment, the reference data is generated by having the sensor 21 pick up sounds generated by driving components of the multifunction device 10, i.e., the motor, and based on the picked-up sounds. If the sensor data acquired in the test mode by driving the motor in the same manner as when generating the reference data does not match the reference data, it can be determined that the sensor 21 is not properly secured in a predetermined position on the multifunction device 10. The storage unit 36 ​​stores the reference data used in the test mode. In this embodiment, reference data related to sound pressure and reference data related to frequency are set in advance as the reference data.

[0029] Each of the components 31 to 35 in the multifunction device 10 is realized by the cooperative operation of a computer installed in the multifunction device 10 and a program running on a CPU 11 included in the computer. The storage unit 36 ​​is realized by an HDD 14 installed in the multifunction device 10. Alternatively, the RAM 13 or an external storage means may be used via a network.

[0030] Furthermore, the programs used in this embodiment can be provided not only by communication means but also by being stored in a computer-readable recording medium such as a USB memory. The programs provided from the communication means or recording medium are installed in a computer, and various processes are realized by the CPU 11 of the computer sequentially executing the programs.

[0031] Next, before describing the operation of this embodiment, the relationship between the components in the multifunction device 10 and the sensor 21 will be described.

[0032] 3 is a diagram illustrating only the sensors 21-1 and 21-2 and the motors 22-1 and 22-2 as components attached to the multifunction device 10 in this embodiment. Note that the sensors 21-1 and 21-2 are collectively referred to as "sensors 21" when there is no need to distinguish between them. Similarly, the motors 22-1 and 22-2 are collectively referred to as "motors 22."

[0033] When diagnosing the sensor 21, in this embodiment, the motor 22 is driven to generate sound, which is then picked up by the sensor 21. For this purpose, the sensor 21 is associated in advance with the motor 22 that generates the sound for that sensor 21. Information linking the sensor 21 and the motor 22 is stored in the storage unit 36. Specifically, the identification information of the sensor 21 is associated with the identification information of the motor 22.

[0034] Basically, it is preferable to drive the motor 22 closest to the sensor 21. As shown in FIG. 3, the sensor 21-1 is linked to the closest motor 22-1, and the sensor 21-2 is linked to the closest motor 22-2. The position of the motor 22 is determined depending on the model of the multifunction device 10, so the sensor 21 is disposed in a position close to the motor 22 where it can be attached. This determines the correspondence between the sensor 21 and the motor 22. In this embodiment, for the sake of convenience, the sensor 21 and the motor 22 have a one-to-one correspondence.

[0035] In this embodiment, the type of motor 22 does not need to be particularly limited. In the case of the multifunction device 10, the motor 22 is considered to be used as a print drive reducer, for emitting laser image signals, for cooling, or for feeding paper. The motor 22 is disposed in an appropriate position depending on the intended use. Furthermore, in this embodiment, the motor 22 is used as the component of the multifunction device 10 that generates sound, but the component does not need to be limited to the motor 22 as long as it is a component other than the motor 22 that generates sound when driven.

[0036] Fig. 4 is a schematic diagram showing a method for installing the sensor 21. While Fig. 3 is a plan view, Fig. 4 is a schematic side view of one sensor 21 shown in Fig. 3 as viewed from the side. Of course, the sensor 21 and the motor 22 do not need to be positioned horizontally inside the multifunction device 10, and may be positioned vertically or at an angle.

[0037] 4, a connector (also called an "attachment jig") 23 to which the sensor 21 is attached is fixed at a predetermined position inside the multifunction device 10. The connector 23 is electrically connected to the input / output interface 19 by a harness (also called "wiring") 24. The sensor 21 has a connection terminal 21a and a microphone 21b. In a broad sense, the sensor 21 and the microphone are both considered to be sound collection means, but in a narrow sense, as shown in FIG. 4, the sensor 21 has a connection terminal 21a attached to the connector 23 and a microphone 21b with a sound collection function. A user inserts the sensor 21 in the direction of arrow A to attach the connection terminal 21a to the connector 23 and electrically connect the microphone 21b to the multifunction device 10.

[0038] In this embodiment, as described above, the sensor 21 is attached to a predetermined position on the multifunction device 10, i.e., the predetermined position where the connector 23 is attached, so that an abnormality occurring in the multifunction device 10 can be detected by analyzing the sound. By attaching multiple sensors 21 to the multifunction device 10, it is also possible to identify the location of the abnormality.

[0039] However, in order for the multifunction device 10 to be able to detect an abnormal part, it is a prerequisite that the sensor 21 operates normally. In other words, for the sensor 21 to operate normally, it is necessary that the sensor 21 itself operates normally, and that the sensor 21 is fixed in a predetermined position. In the present embodiment, the process of diagnosing whether the sensor 21 operates normally will be described below using the flowchart shown in FIG. 5. Note that even if multiple sensors 21 are attached to the multifunction device 10, the process described below can be repeated for each sensor 21, so the following description will focus on one sensor 21.

[0040] First, the user starts up the multifunction device 10 by turning on the power without the sensor 21 attached. Once the multifunction device 10 is started up, the user selects the test mode by performing a predetermined operation on the operation panel 15. The control unit 31 controls the multifunction device 10 to operate in the test mode in response to the user's operation. This allows the sensor 21 to be diagnosed.

[0041] When the system enters the test mode, a predetermined test program starts to run, which causes the test execution unit 32 to start processing. First, the test execution unit 32 causes the data receiving unit 34 to constantly receive sensor data output from the sensor 21 (step 111). In other words, during the test mode, the system is in a state where it can constantly receive sensor data.

[0042] Incidentally, at the start of the test mode, the sensor 21 is not attached to the connector 23, so no sound is picked up. Therefore, the sensor data value should normally be zero (0), so the test execution unit 32 first confirms that the sensor data value is zero (step 112). If the sensor data value is not zero, this means that there is an abnormality between the connector 23 and the input / output interface 19, or that a sensor 21 that should not be attached is attached, and the test execution unit 32 notifies the user of this by, for example, causing the display control unit 35 to display a message to that effect on the operation panel 15. This allows the user to take some kind of action.

[0043] Next, the user attaches the sensor 21 to the connector 23 attached at a predetermined position. When the sensor 21 is attached to the connector 23, it starts picking up sound. Therefore, the sensor data value should not normally be zero (0). This is because there is always environmental sound around the multifunction device 10. When it detects that the sensor 21 has been attached, the test execution unit 32 verifies that the sensor data value is not zero (step 113). If the sensor data value is zero, this indicates that there is an abnormality between the sensor 21 and the input / output interface 19, and the test execution unit 32 notifies the user by, for example, causing the display control unit 35 to display a message to that effect on the operation panel 15. This allows the user to take some kind of action.

[0044] Next, when the attachment of the sensor 21 is confirmed, the test execution unit 32 refers to the storage unit 36 ​​to identify the motor 22 associated with the identified sensor 21, and causes the operation control unit 33 to drive the identified motor 22 (step 114). As a result, the motor 22 starts to operate, but the content of the operation is predetermined, and specifically, the content of the operation is the same as when the reference data was recorded.

[0045] In addition, when a test is performed by attaching multiple sensors 21 in sequence, the test execution unit 32 can identify the attached sensor 21 by referring to the identification information of the sensor 21 (e.g., "sensor ID") added to the sensor data.

[0046] The operating sound of the motor 22 is picked up by the sensor 21. The test execution unit 32 records the sensor data output from the sensor 21 by the picked-up sound in the storage unit 36 ​​(step 115). There is no particular need to limit the recording time, etc., as long as it is possible to compare the recorded sensor data with reference data.

[0047] Next, the test execution unit 32 analyzes the recorded sensor data to obtain the sound pressure and frequency of the sound picked up by the sensor 21 (step 116). Then, the test execution unit 32 compares the sound pressure obtained from the sensor data (hereinafter also referred to as "measured sound pressure value") with reference data on the sound pressure corresponding to the motor 22 associated with the sensor 21, and determines whether the measured sound pressure value matches the reference data.

[0048] Here, "match" does not necessarily mean that the sound pressure measurement value matches the reference data perfectly, but also means that a tolerance is set for the deviation of the sound pressure measurement value from the reference data, and the sound pressure measurement value is considered to match if it is within that tolerance. The same applies to the measurement value being a frequency.

[0049] If the measured sound pressure value does not match the reference data (N in step 117), the test execution unit 32 determines that the measured sound pressure value is an abnormal value. Next, the test execution unit 32 compares the frequency obtained from the sensor data (hereinafter also referred to as the "measured frequency value") with reference data related to the frequency corresponding to the motor 22 associated with the sensor 21, and determines whether the measured frequency value matches the reference data. If the measured frequency value matches the reference data (Y in step 118), the test execution unit 32 determines that the measured sound pressure value is normal.

[0050] In this way, if the sound pressure measurement value is abnormal but the frequency measurement value is normal, it is determined that the distance between the sensor 21 and the motor 22 associated with that sensor 21 is incorrect, that is, the sensor 21 may not be correctly attached to the predetermined position. More specifically, it is determined that the connection terminal 21a may not be inserted properly into the connector 23 and may not be attached all the way.

[0051] In this case, the test execution unit 32 diagnoses that the sensor 21 is malfunctioning and displays the diagnosis result indicating that the sensor 21 is malfunctioning. In this embodiment, the diagnosis result does not simply notify the user of the malfunction, but rather displays instructions for resolving the malfunction, i.e., instructions to correctly attach the sensor 21 in a predetermined position. More specifically, the test execution unit 32 causes the display control unit 35 to display on the operation panel 15 a message instructing the user to check that the sensor 21 is attached properly (step 119).

[0052] On the other hand, if the measured sound pressure value matches the reference data (Y in step 117), the test execution unit 32 determines that the measured sound pressure value is normal. Next, as described above, the test execution unit 32 compares the measured frequency value obtained from the sensor data with reference data related to the frequency corresponding to the motor 22 associated with the sensor 21, and determines whether the measured frequency value matches the reference data. Here, if the measured frequency value does not match the reference data (N in step 120), the test execution unit 32 determines that the measured frequency value is abnormal.

[0053] In this way, if the sound pressure measurement value is normal but the frequency measurement value is abnormal, it is determined that the sensor 21 may be vibrating for some reason. For example, it is determined that the sensor 21 may be correctly attached to a predetermined position, but the connector 23 may not be securely fixed to the housing of the multifunction device 10, causing the sensor 21 to vibrate along with the connector 23.

[0054] In this case, the test execution unit 32 diagnoses that the sensor 21 is malfunctioning and displays the diagnosis result indicating that the sensor 21 is malfunctioning. In this embodiment, the diagnosis result does not simply notify the user of the malfunction, but rather displays instructions for resolving the malfunction, i.e., instructions to properly secure the sensor 21. In the above example, the test execution unit 32 causes the display control unit 35 to display on the operation panel 15 a message instructing the user to check whether the connector 23 is secured to the housing of the multifunction device 10 (step 121).

[0055] Furthermore, if neither the sound pressure measurement value nor the frequency measurement value matches the respective reference data (N in step 117, N in step 118), the test execution unit 32 determines that both the sound pressure measurement value and the frequency measurement value are abnormal.

[0056] In this case, the test execution unit 32 diagnoses that the sensor 21 is malfunctioning and displays the diagnosis result indicating that the sensor 21 is malfunctioning. In this embodiment, the diagnosis result does not simply notify the user of the malfunction, but rather displays instructions for resolving the malfunction, i.e., instructions to properly attach the sensor 21 to a predetermined position and to properly secure it. More specifically, the test execution unit 32 causes the display control unit 35 to display on the operation panel 15 a message instructing the user to check the state of the connector 23 and to try attaching the sensor 21 again from the beginning (step 122).

[0057] If the sound pressure measurement value and the frequency measurement value repeatedly do not match the respective reference data even when the user repeatedly takes action in accordance with the instructions displayed on the operation panel 15, the sensor 21 itself may be broken, and therefore the test execution unit 32 may display an instruction to replace the sensor 21 on the operation panel 15. Furthermore, if the sound pressure measurement value and the frequency measurement value still do not match the respective reference data even after the sensor 21 has been replaced, it is possible that the motor 22 has broken down and is not generating sound with the same sound pressure and frequency as the reference data, and therefore a message to that effect may be displayed on the operation panel 15.

[0058] Furthermore, if both the sound pressure measurement value and the frequency measurement value match the respective reference data (Y in step 117, Y in step 120), the test execution unit 32 determines that the sensor 21 is properly attached and that the connector 23 is fixed to the housing of the multifunction device 10. In other words, the test execution unit 32 determines that the sensor 21 operates normally. In this case, the test execution unit 32 causes the display control unit 35 to display a message on the operation panel 15 indicating that the sensor 21 operates normally (step 123). This ends the processing of the test execution unit 32, and the control unit 31 ends the test mode.

[0059] According to this embodiment, as described above, the operation of the sensor 21 can be diagnosed in the test mode that is executed before the multifunction device 10 is put into use. If the sensor 21 is diagnosed as malfunctioning, the malfunction diagnosis result and instructions for resolving the malfunction of the sensor 21 are displayed on the operation panel 15. The test mode may be executed in a factory before the multifunction device 10 is newly installed at a customer's site. Furthermore, if a customer wants to avoid leaving the sensor 21 attached to the multifunction device 10 because of the risk of eavesdropping, the test mode may be executed at the customer's site before starting maintenance and inspection work on the customer's multifunction device 10. In this case, a maintenance technician will bring the sensor 21 and attach it to the multifunction device 10 at the customer's site.

[0060] If the sensor 21 detects an abnormal sound after its operation has been confirmed, then it can be assumed that an abnormality has occurred in one of the components inside the multifunction device 10. If multiple sensors 21 are attached to the multifunction device 10, it becomes possible to identify the location where the abnormality has occurred.

[0061] In the above description, for convenience of explanation, the sensor 21 and the motor 22 have a one-to-one relationship, but multiple motors 22 may be associated with one sensor 21. By performing the above-described diagnosis on each of the multiple motors 22 for one sensor 21, multiple diagnosis results can be obtained. This can improve the accuracy of the diagnosis results for the sensor 21.

[0062] In the above embodiments, the term "processor" refers to a processor in a broad sense, and includes general-purpose processors (e.g., CPU: Central Processing Unit, etc.) and dedicated processors (e.g., GPU: Graphics Processing Unit, ASIC: Application Specific Integrated Circuit, FPGA: Field Programmable Gate Array, programmable logic device, etc.).

[0063] Furthermore, the operations of the processors in the above embodiments may not only be performed by a single processor, but may also be performed by multiple processors located at physically separate locations working together. Furthermore, the order of the operations of the processors is not limited to the order described in the above embodiments, and may be changed as appropriate. [Explanation of symbols]
