  The present invention relates to a program or the like for notifying an operator of an error of an electronic device, and in particular, can provide error information that can be easily recognized by the operator and accurately notify the operator of more detailed error information using the apparatus. The present invention relates to an error notification program and the like.

  Conventionally, when an error occurs in a receipt printer, the receipt printer is shot with a video using a mobile terminal, etc., and the information corresponding to the internal status of the receipt printer from the shooting result (appropriate handling information according to the error code, etc.) Has been proposed (for example, see Patent Document 1 below).

JP2015-52816A

  However, in the method disclosed in Patent Document 1, the method of notifying an error is only the blinking of the LED attached to the printer, and it is desired to express more detailed error contents to the operator. Has its limits. In addition, if the expression due to blinking of the LED is complicated, it is difficult for humans to understand, and there is a possibility that the operator may misrecognize.

  Therefore, an object of the present invention is to provide an error notification program that can provide error information that can be easily recognized by the operator and that can accurately notify the operator of more detailed error information using the apparatus. It is to provide.

  In order to achieve the above object, according to one aspect of the present invention, there is provided an acquisition step in which a program for causing a mobile terminal device to perform error notification processing acquires a warning sound and a warning light of an electronic device, and the acquired warning A pattern generation step of generating an intensity pattern of sound and warning light, a notification information determination step of determining notification information based on the generated intensity pattern, and a notification step of notifying the determined notification information And causing the mobile terminal device to execute.

  Thus, since the notification information can be associated with each combination of the warning sound and the intensity pattern of the warning light, a large amount of information can be notified. Furthermore, since the large number of pieces of notification information are expressed by two media of a warning sound and a warning light, it is possible to simplify the representation by one medium and it is easy for the operator to recognize.

  In the above invention, a preferred aspect is that the mobile terminal device stores a sound and light intensity pattern associated with the notification information, and the notification information determined in the notification information determination step is generated as described above. The notification information associated with the stored sound and light intensity patterns that matches the warning sound and light intensity patterns.

  This simplifies the process of acquiring notification information corresponding to the warning sound and warning light intensity patterns stored in the mobile terminal device, and facilitates the implementation of the error notification program.

  Furthermore, in the above invention, a preferred aspect is characterized in that the warning sound emitted from the electronic device and the intensity pattern of the warning light have the same shape and are emitted with a phase difference.

  This makes it possible to notify a lot of detailed information on errors that occur in the electronic device.

  In the above-mentioned invention, a preferred aspect is characterized in that the shape of the intensity pattern represents a classification of an error that has occurred in the electronic device, and the phase difference represents detailed information of the error.

  As a result, the classification of errors can be expressed in an easy-to-understand manner for humans by the warning sound and warning light intensity patterns emitted by the electronic device. Furthermore, more detailed error states can be notified to the operator by two notification media of warning light and warning sound. Furthermore, since detailed error information is associated with phase difference information of the intensity pattern, a large amount of detailed information on errors occurring in the electronic device can be notified.

  In the above invention, a preferable aspect is that the notification in the notification step is at least one of display on the screen of the mobile terminal device, notification by voice, or transmission by e-mail. And

A pattern generation step for generating the intensity pattern, a notification information determination step for determining notification information based on the generated intensity pattern, and a notification step for notifying the determined notification information. .

  In order to achieve the above object, still another aspect of the present invention is that, when an error occurs, the electronic device emits a warning sound and a warning light having the same intensity pattern and having a phase difference.

  Thus, if the same intensity pattern represents the error classification and the detailed information of the error is expressed by the phase difference, the detailed information of many errors can be notified with a small intensity pattern. In addition, since it is expressed with a small intensity pattern, it is easy for the operator to understand.

  In order to achieve the above object, according to still another aspect of the present invention, in an error notification system including an electronic device and a mobile terminal device, the electronic device has the same intensity pattern and is mutually relative when an error occurs. A notification unit that emits a warning sound and a warning light having a phase difference, the mobile terminal device acquiring a warning sound and a warning light of the electronic device, and an intensity pattern of the acquired warning sound and the warning light A pattern generation unit that generates a notification, a notification information determination unit that determines notification information based on the generated intensity pattern, and a notification unit that notifies the determined notification information.

  FIG. 2 is a diagram exemplifying data of error groups and states, corresponding sound and light intensity patterns, and phase differences thereof registered in the pattern data DB 301. A solid line indicates a light intensity pattern, and a broken line indicates a sound intensity pattern. For example, the light intensity pattern shown in (1) indicates “a temperature related error” in the error “group”. The intensity pattern of the sound and light having the phase difference shown in (1a) indicates the “state” of the error “print head is hot” included in the “group” of the “some error related to temperature”. , (1b) indicates a “state” that “the other part is hot”. Further, the light intensity pattern shown in (2) indicates “an error in the transport system” of the “group” of errors. The intensity pattern of the sound and light having the phase difference shown in (2a) is the “state of the movable part on-position” included in the “group” of the “any error in the transport system”. (2b) shows a “state” that “paper jam has occurred”. Further, (2c) shows a state that “paper cannot be fed”. For other “groups” and “states”, the corresponding “light intensity pattern” and “sound and light intensity pattern and phase difference” are also stored as shown in FIG. Yes.

A DB 235 and an error display unit (notification unit) 234 are provided.

  The error notification unit 23 is a dedicated application that, when an error occurs in the printer 3, images the printer 3 in the error notification state, determines the error state from the captured moving image data, and notifies the error. If the operator wants to know the error status or cannot recognize the error content, the operator acquires the status of the error that has occurred in the printer 3 by using the dedicated application (error notification unit 23). can do. Further, after acquiring the captured moving image data, the error notification unit 23 acquires the intensity pattern and the phase difference in the pattern generation unit 232 described later, and the state of the printer 3 that notifies the operator in the notification information determination unit 233. To decide. When the state is determined, the error display unit 234 of the error notification unit 23 displays the error state on the display 34 to notify the operator of the error state of the printer 3. Details regarding the acquisition of the intensity pattern and the phase difference by the pattern generation unit 232 will be described later.

  The data acquisition unit 231 is a part that acquires, in the application layer, moving image data captured by the camera 21 in the error notification unit 23. The moving image data shot by middleware or the like that operates the camera 21 is transferred to the data acquisition unit 231. The data acquisition unit 231 passes the moving image data to the pattern generation unit 232 after acquiring the data.

  The pattern generation unit 232 acquires image data representing blinking of the light emitted by the LED 33 and buzzer sound data emitted from the speaker 35 from the moving image data passed from the data acquisition unit 231, and finalizes these data. This is the part that converts to sound and light intensity patterns. Details of the method for generating the sound and light intensity patterns will be described later.

  The notification information determination unit 233 is a part that determines an error state and a coping method corresponding to the error state as notification information (comment) to be notified to the operator. The notification information determination unit 233 determines a group from the sound and light intensity patterns generated by the pattern generation unit 232, and determines a state from the phase difference between them.

  In the notification information DB 235, notification information (comments) that contains the same data as the pattern data DB 301 on the printer 3 side and is acquired by the notification information determination unit 233 and describes the details of the error to be notified to the operator is registered ( It is a database that is stored. The notification information (comment) is associated with the corresponding error status, and information on the error status to be notified and the coping method corresponding to each status (for example, in text format) is registered. Yes. For example, in the case of “paper jam has occurred” shown in the “status” of the error in FIG. 2, “paper jammed. Check inside the printer.” A comment describing the coping method corresponding to the state is registered. The notification information DB 235 is configured with a nonvolatile memory or the like as a hardware configuration.

  The error display unit (notification unit) 234 is a part that notifies the display 24 of the notification information (comment) determined by the notification information determination unit 233.

  In addition, the error notification unit 23 is configured by an application program, a CPU that operates according to the program, a RAM, and the like, that is, the data acquisition unit 231, the pattern generation unit 232, the notification information determination unit 233, and the error display unit 234. . The application program is an application that can be installed and used in the mobile terminal 2 by downloading from a predetermined site (for example, a printer manufacturer's homepage).

  The camera 21 is a camera mounted on the mobile terminal 2 for shooting still images and moving images. Although not shown, the hardware configuration includes a lens, a sensor, and the like. The camera 21 is activated when a dedicated application (error notification unit 23) is activated and an activation operation is performed by the operator.

  The display 24 is a display unit of the mobile terminal 2 configured by a liquid crystal display device or the like. When the error notification unit 23 notifies the operator of the error state, the content is displayed on the display 24.

  The microphone 23 is a microphone mounted on the mobile terminal 2 for collecting voice. Similarly to the camera 21, a buzzer mainly emitted from the speaker 35 is activated when the camera activation button of the mobile terminal 2 is pressed by the operator or simultaneously with the dedicated application (error notification unit 23). To collect the sound.

  The error notification system 1 having the above configuration is characterized by an error notification process for the operator, and the specific contents thereof will be described below.

  First, the notification process on the printer 3 side will be described with reference to FIG. Here, it is assumed that the error “group” illustrated in FIG. 2 is “control system error” and the error “status” is “memory access error has occurred”. This will be described with reference to the flowchart of FIG.

  FIG. 3 is a flowchart of the notification process on the printer 3 side.

  The error assumed above occurs in the printer 3 (step S2 in FIG. 3). When the error occurs, the error detection unit 304 detects an error occurrence event (step S4 in FIG. 3). When the event is detected, the error detection unit 304 notifies the notification signal generation unit 303 of the error group and the error state.

  When the notification signal generation unit 303 receives the error group and the error state, the notification signal generation unit 303 searches the pattern data DB 301, and the sound and light intensity patterns corresponding to the error state (here, the data of (3b) in FIG. 2). ). The notification signal generator 303 generates a sound and light output signal that emits sound and light with the called intensity pattern (step S6 in FIG. 3).

  Next, the notification unit 302 sends the sound and light output signals generated in step S6 to the LED 33 and the speaker 35 (step S8 in FIG. 3).

  The LED 33 that has received the signal sent in step S8 blinks the light according to the received output signal, and the speaker 35 sounds a buzzer sound according to the received output signal to notify the occurrence of an error ( Step S10 in FIG.

  Through the processing described above, when an error occurs in the printer 3, the operator is notified of the error. By this notification, the operator identifies an error group from the blinking pattern of the LED 33 and the ringing pattern of the speaker 35. Thereafter, the operator activates a dedicated application (error notification unit 23) installed in the mobile terminal 2 in order to know the error state, and photographs the printer 3 that has notified the error.

  FIG. 4 is a diagram illustrating a state in which the printer 3 is photographed by the dedicated application (error notification unit 23) installed in the mobile terminal 2. As shown in FIG. 4, when the printer 3 is photographed by the error notification unit 23, the blinking state is photographed by placing the LED 33 in the frame F displayed by the error notification unit 23 on the display 24. To do. By taking an image in this way, it is possible to limit the place where the light intensity pattern determination process described later is performed only to the peripheral portion of the LED 33.

  FIG. 5 is a flowchart showing error notification processing on the mobile terminal 2 side.

  As described above, the operator activates the dedicated application (error notification unit 23) installed in the mobile terminal 2 in order to recognize the error state. Thereafter, as described with reference to FIG. 4, the operator uses the dedicated application (error notification unit 23) to photograph the printer 3 reporting the error with a moving image (step S <b> 12 in FIG. 5).

  Next, the error notification unit 23 acquires the moving image data captured in step S12 by the data acquisition unit 231 (step S14 in FIG. 5). Specifically, since the moving image data is sequentially passed from the middleware (not shown) dedicated to the camera 21 to the application layer while being captured by the camera 21, the data acquisition unit 231 receives the moving image data passed from the middleware. To get.

  Next, the pattern generation unit 232 creates intensity data from the moving image data acquired in step S14 (step S16 in FIG. 5). The intensity data is data representing the intensity of sound and light emitted from the LED 33 and the speaker 35 that are the subject of photographing in time series. First, the pattern generation unit 232 creates sound intensity data from audio data included in the acquired moving image data. Specifically, sound intensity data is generated by converting the acquired audio data into a frequency band signal using discrete Fourier transform processing. More specifically, the pattern generation unit 232 extracts audio data mainly from the moving image data acquired in step S14, and outputs a sound signal included in the data for a certain time (here, 0.05 (seconds). Sampling is performed every time. Then, the pattern generation unit 232 creates a plurality of sampled data (in this case, 200) and converts the data into frequency band intensity data by performing a discrete Fourier transform process. In this manner, the pattern generation unit 232 creates sound intensity data obtained by converting a time-series sound signal into intensity for each frequency. Here, as a method of creating sound intensity data, discrete Fourier transform or other methods may be used.

  Next, the pattern generation unit 232 creates light intensity data. The pattern generation unit 232 first analyzes the data in the frame F for the acquired image data of the moving image data, and determines the image area of the LED 33. Regarding light data, unlike sound data, the intensity of light can be directly discriminated from image data included in captured (acquired) moving image data. Here, the pattern generation unit 232 analyzes the image data included in the image region in time series to create light intensity data.

  Next, the pattern generation unit 232 performs threshold processing on the sound intensity data created in step S16 using a predetermined threshold, and has intensity data having an obvious uneven shape (generally pulse shape). Convert to Similar processing is performed on the light intensity data to generate similar intensity data.

  Next, the pattern generation unit 232 obtains a sound and light intensity pattern by extracting the uneven portion from both the intensity data. Furthermore, the acquired both intensity patterns are put on the same time axis, and the phase difference between them is acquired (step S18 in FIG. 5).

  Next, the pattern generation unit 232 accesses the notification information DB 235, compares the intensity pattern acquired in step S18 with the data of “sound and light intensity pattern and phase difference”, and finds a match. The corresponding notification information (comment) is read (step S20 in FIG. 5). In this case, notification information (comment) corresponding to the state that “memory access error has occurred” (for example, corresponding notification information (comment) such as “memory access error has occurred. Please reset the printer”). ) Get and decide.

  Next, the error display unit 234 of the mobile terminal 2 displays the notification information (comment) determined in step S20 on the display 24 (step S22 in FIG. 5). The operator recognizes the error state from the display displayed on the display 24, and recognizes a corresponding coping method and the like. Even when an error other than the “memory access error” assumed this time occurs, the same processing as described above is performed.

  Note that the electronic device in which the error occurs is not limited to the printer 3 but may be a scanner, a projector, or the like.

  In addition, the method of notifying the operator of the error state and the corresponding coping method in the error notification unit 23 is not only displayed on the display 24 of the mobile terminal 2 but also notification by e-mail (transmission by e-mail) Other methods such as reading out the error state by voice (notification by voice) may be used. Or any combination thereof may be used.

  As described above, in the error notification system 1 according to the present embodiment, the printer 3 notifies the operator of an error that has occurred in the printer 3 that is an electronic device. The notification is made by the LED 33 and the speaker 35. The intensity pattern of the light emitted from the LED 33 and the sound emitted from the speaker 35 is simple and the same shape, and there is a phase difference depending on the error state. In addition, the dedicated application (error notification unit 23) installed in the mobile terminal 2 captures a moving image of the printer 3 that is generating an error, and notifies the operator of a coping method corresponding to the error state.

  Therefore, when an error occurs in the printer 3, the printer 3 is photographed by the dedicated application (error notification unit 23) installed in the mobile terminal 2, so that a coping method corresponding to the error state can be acquired immediately. Can do.

  Also, the sound and light intensity patterns emitted by the printer 3 have the same shape and are emitted with a phase difference from each other, so that the correspondence between each error state and the sound and light intensity patterns is simplified, and error notification is performed. Easy program implementation. Furthermore, a rough group of errors can be expressed by the intensity pattern of sound and light, and a detailed error state can be expressed by information on the phase difference of these intensity patterns. Thereby, the operator can first roughly recognize the error by the blinking pattern of the LED 33 or the sound emitted from the speaker 35, and can notify the operator of a more detailed error state.

  In addition, by expressing the detailed error state by information on the phase difference between the sound intensity pattern and the light intensity pattern, many error states that occur in the printer 3 can be expressed.

  In addition, since the error notification is performed by at least one of display on the screen of the mobile terminal device, notification by voice, or transmission by e-mail, the error status is immediately notified in an appropriate manner for the operator. The user convenience can be improved.

  In addition, since the mobile terminal 2 can be configured as the error notification system 1 only by installing the error notification program, it can be applied to various systems.

  The protection scope of the present invention is not limited to the above-described embodiment, but covers the invention described in the claims and equivalents thereof.
