BEST MODE FOR CARRYING OUT THE INVENTION

[0012] Next, the embodiments will be described in detail with reference to the drawings.

[0013] FIG. 1 is a block diagram showing the configuration of a maintenance work support device 100 in the first embodiment. Referring to FIG. 1, the maintenance work support device 100 includes a detection unit 101, a selection unit 102, and an execution control unit 103. The maintenance work support device 100 is provided, for example, by a service provider entrusted with maintenance support services such as maintenance and repair of facilities installed in a store. The maintenance work support device 100 provides maintenance support services to store employees and the like through a mobile terminal 200 in the store via a network. The maintenance support service includes, for example, receiving the provision of maintenance work information necessary for maintenance work, connecting to the provider (call center) of the maintenance support service and performing maintenance work while communicating such as having a conversation or a chat, or having a maintenance worker dispatched. In the present embodiment, the mobile terminal 200 includes a dedicated terminal, a terminal having a display screen such as a smartphone or a notebook PC, and a wearable device worn by a user such as a smartwatch or smart glasses. FIG. 1 shows a block diagram when a smart glass is used as the mobile terminal 200 in the present embodiment. Next, the configuration of the maintenance work support device 100 in the first embodiment will be described in detail.

[0014] FIG. 2 is a diagram showing an example of a hardware configuration in which the maintenance work support apparatus 100 according to the first embodiment of the present disclosure is realized by a computer apparatus 500 including a processor. As shown in FIG. 2, the maintenance work support apparatus 100 includes a CPU (Central Processing Unit) 501, a ROM (Read Only Memory) 502, a memory such as a RAM (Random Access Memory) 503, a storage device 505 such as a hard disk that stores a program 504, a communication I / F (Interface) 508 for network connection, and an input / output interface 511 for inputting and outputting data. In the first embodiment, the error information of the facility received by the detection unit 101 is input to the maintenance work support apparatus 100 via the communication I / F 508 for network connection. In the first embodiment, the maintenance work support apparatus 100 is connected to an input device 509 and an output device 510 via a bus 512. Further, the maintenance work support apparatus 100 in the first embodiment shown in FIG. 1 can also be configured by cloud computing or the like.

[0015] The CPU 501 operates an operating system to control the entire maintenance work support apparatus 100 according to the first embodiment of the present invention. Further, the CPU 501 reads programs and data from a recording medium 506 mounted on, for example, a drive device 507 into the memory. Further, the CPU 501 functions as a part of the detection unit 101, the selection unit 102, and the execution control unit 103 in the first embodiment, and executes the processing or instructions in the flowchart shown in FIG. 6 described later based on the program.

[0016] The recording medium 506 is, for example, an optical disk, a flexible disk, a magneto-optical disk, an external hard disk, or a semiconductor memory. A semiconductor memory or the like that is a part of the recording medium is a non-volatile storage device, and a program is recorded therein. Further, the program may be downloaded from an external computer (not shown) connected to the communication network.

[0017] The input device 509 is realized by, for example, a mouse, a keyboard, or built-in key buttons, and is used for input operations. The input device 509 is not limited to a mouse, a keyboard, or built-in key buttons, and may be, for example, a touch panel or a microphone for voice input. In the first embodiment, the output device 510 is realized by, for example, a display, and is used to check the output.

[0018] As described above, the first embodiment shown in FIG. 1 is realized by the computer hardware shown in FIG. 2. However, the means for realizing each unit of the maintenance work support device 100 in FIG. 1 is not limited to the configuration described above. The maintenance work support device 100 may be realized by one physically combined device, or may be realized by a system consisting of two or more physically separated devices connected by wire or wirelessly. For example, the input device 509 and the output device 510 may be connected to the computer device 500 via a network. In the first embodiment, the detection unit 101 of the maintenance work support device 100 may be realized by the mobile terminal 200, and the other configurations may be realized by the computer device 500.

[0019] The detection unit 101 is a means for detecting the necessity of equipment maintenance work. The equipment is, for example, equipment installed in a store or office, which requires recovery work when an error occurs and regular maintenance work. Examples of the equipment include coffee machines, refrigerators, POS terminals, multifunction devices, and multimedia terminals installed in convenience stores. Equipment maintenance work includes, for example, operating the equipment, clearing errors, replacing or replenishing equipment, washing or cleaning, and the like. Maintenance means, for example, monitoring the state of the equipment, detecting or predicting an abnormal state of the equipment, and replacing, inspecting, or repairing the equipment.

[0020] The detection unit 101 detects the necessity of maintenance work, for example, by receiving information indicating that an error has occurred in the equipment. Next, the detection unit 101 identifies the content of the necessary maintenance work based on the error identification information obtained by photographing the equipment when the error occurred. The error identification information is an image in which an identifier specifying the error content such as an error code is displayed when an error occurs in the equipment, or an image obtained by photographing the appearance or interior of the equipment when the error occurs. In this case, the appearance or interior of the equipment is photographed by a photographing device such as a surveillance camera in a store or the like or a camera provided in the mobile terminal 200. The detection unit 101 identifies the error content and the content of the necessary maintenance work by analyzing the identifier specifying the error content and the image of the photographed equipment. The content of the necessary maintenance work for the error content is stored in the storage device 505, for example, in association with an identifier such as an error code or an image of the equipment at the time of error occurrence.

[0021] The detection unit 101 may detect the necessity of maintenance work based on the maintenance history of the equipment. For example, the necessity of maintenance work may be detected when a certain period (for example, several months) or more has elapsed since the previous maintenance work was carried out. Further, the detection unit 101 may search for the presence or absence of the necessity of maintenance work for the equipment triggered by detecting that the user has performed an operation to confirm the necessity of maintenance work for the equipment. The operation to confirm the necessity of maintenance work includes, for example, opening a dedicated application as necessary and photographing the target equipment, or reading a barcode for identifying the target equipment. When the mobile terminal 200 is smart glasses, the operation to confirm the necessity of maintenance work may include, in addition to the above operations, wearing the smart glasses and receiving error information of the equipment from the equipment in the store via a network to detect the necessity of maintenance work. When the detection unit 101 detects that there is a necessity for maintenance work on the equipment, it outputs the content of the necessary maintenance work to the selection unit 102.

[0022] The selection unit 102 is a means for selecting a maintenance support method based on the content of the detected maintenance work. When the content of the necessary maintenance work is input from the detection unit 101, the selection unit 102 selects a support method for the maintenance work corresponding to the input maintenance work. The selection unit 102 selects a support method based on, for example, the difficulty level of the specified maintenance work. Examples of the difficulty level of the maintenance work include information such as the estimated time required for the maintenance work, the number of steps of the maintenance work, or the maintenance work history information of the person performing the maintenance work. The maintenance work history information also includes information about the support methods provided to the person performing the maintenance work in the past for the same or similar error contents and maintenance work contents. When the selection unit 102 selects a support method based on the maintenance work history information, even for a maintenance work that can generally be handled by showing a maintenance work method such as a manual, the support method may be changed according to the work level of the person performing the maintenance work. For example, if the person performing the maintenance work has a history of inquiring at the call center about the target maintenance work or the number of inquiries is above a certain level, instead of showing the maintenance work method, it may be possible to directly connect to the call center. That is, the selection unit 102 may select a support method based not only on the objective difficulty level of the maintenance work but also on the subjective difficulty level of the person performing the maintenance work.

[0023] Examples of the options for the support method selected by the selection unit 102 include display of the maintenance work method, connection to the call center, or dispatch of a maintenance staff. Display of the maintenance work method means displaying a manual or the like showing the maintenance work procedure on the screen of the mobile terminal 200. Connection to the call center means connecting to the provider of the maintenance support service through a fixed telephone line or network to receive the necessary support. Dispatch of a maintenance staff means sending a maintenance staff to the installation location of the equipment that requires maintenance. For example, when the difficulty level of the maintenance work is low, the selection unit 102 selects to display the maintenance work method on the screen of the mobile terminal 200. For example, when the difficulty level of the maintenance work is high, the selection unit 102 selects to dispatch a maintenance staff. When the selection unit 102 selects a support method for the maintenance work, it outputs the information of the selected support method to the execution control unit 103.

[0024] The execution control unit 103 is a means for executing the support method selected by the selection unit 102. When the information on the selected support method is input from the selection unit 102, the execution control unit 103 starts supporting the maintenance work through the mobile terminal 200. When the display of the maintenance work method is selected as the support method, the execution control unit 103 causes the maintenance work method to be displayed on the screen of the mobile terminal 200. The display form includes video, image, voice, or message.

[0025] When the connection to the call center is selected as the support method, the execution control unit 103 makes the mobile terminal 200 capable of making a call through the microphone and speaker of the mobile terminal 200 by connecting to the call center via a fixed telephone line or network connection. Further, the execution control unit 103 may make it possible to view the image transmitted from the call center through the display screen of the mobile terminal 200. The execution control unit 103 may share an image showing the state of the equipment during the maintenance work with the call center through the imaging device of the mobile terminal 200.

[0026] When the support method is a call from a maintenance staff member, the execution control unit 103 notifies the terminal of the service provider entrusted with the maintenance support service for the target equipment that the call from the maintenance staff member has been selected. Further, the execution control unit 103 may directly send a message to the maintenance staff member to perform the maintenance of the equipment.

[0027] FIG. 3, FIG. 4, and FIG. 5 are examples of screens showing the content of the maintenance work method displayed by the execution control unit 103. The examples of the screens shown in FIGS. 3, 4, and 5 are examples showing the content of the maintenance work of the coffee machine. As shown in FIG. 3, for example, based on the maintenance work method, information A indicating the direction in which the equipment is actually moved as seen from the user may be displayed on the display screen D in the direction of moving the equipment. Also, as shown in FIG. 4, the maintenance work method may be displayed in the order of work. Further, when the execution control unit 103 detects a click operation from the input device 509 of the person performing the maintenance work, as shown in FIG. 5, the work information during the maintenance work may be enlarged and displayed. Further, the execution control unit 103 may identify the work content during the maintenance work based on the image data obtained by photographing the state of the equipment during the maintenance work with the photographing device of the store or the mobile terminal 200, and display the identified maintenance work method during the maintenance work. Also, when the mobile terminal 200 is a smart glass, the work content during the maintenance work may be identified based on the state of the equipment that the person performing the maintenance work is looking at through the lens, and the maintenance work method during the maintenance work may be displayed.

[0028] The operation of the maintenance work support device 100 configured as described above will be described with reference to the flowchart of FIG. 6.

[0029] FIG. 6 is a flowchart showing an overview of the operation of the maintenance work support device 100 in the first embodiment. Note that the processing according to this flowchart may be executed based on program control by the above-described processor.

[0030] As shown in FIG. 6, first, when the detection unit 101 detects the necessity of maintenance work of the equipment, the detection unit 101 outputs the content of the detected maintenance work to the selection unit 102 (step S101). Next, the selection unit 102 selects a maintenance support method based on the content of the detected maintenance work, and outputs information indicating the selected support method to the execution control unit 103 (step S102). Finally, the execution control unit 103 executes the selected support method (step S103). Thus, the maintenance work support device 100 ends the operation of supporting the maintenance work.

[0031] In the maintenance work support device 100 in the above-described embodiment, the selection unit 102 selects a maintenance support method based on the detected maintenance content. Thereby, it becomes possible to automatically execute the support for the maintenance work required for the facility.

[0032] [Modification Example of the First Embodiment] In the first embodiment, the selection unit 102 selects the support method based on the difficulty level of the maintenance work. However, the selection of the support method is not limited to this. For example, the selection unit 102 may select the support method based on the analysis result of the image obtained by the detection unit 101 photographing the state of the facility. When there is a physical failure in the analysis result of the image by the detection unit 101, the selection unit 102 may select to call a maintenance staff. On the other hand, when there is no physical failure in the analysis result of the image by the detection unit 101, the selection unit 102 may support the error code in a predetermined method. When the error code cannot be confirmed even when there is no physical failure in the above-described analysis result, the selection unit 102 may select to connect to the call center. The predetermined support method for the error code is stored in, for example, the storage device 505.

[0033] [Second Embodiment] Next, a second embodiment of the present disclosure will be described in detail with reference to the drawings. Hereinafter, the description of the content overlapping with the above description will be omitted as long as the description of this embodiment is not made unclear. Each component in each embodiment of the present disclosure can be realized by a computer device based on program control or firmware, as well as realizing its function hardware-wise, similar to the computer device shown in FIG. 2.

[0034] FIG. 7 is a block diagram showing the configuration of the maintenance work support device 110 according to the second embodiment of the present disclosure. Referring to FIG. 7, the maintenance work support device 110 according to the second embodiment will be described, centering on the parts different from the maintenance work support device 100 according to the first embodiment. The maintenance work support device 110 according to the second embodiment includes a detection unit 111, a difficulty determination unit 112, a selection unit 113, an execution control unit 114, and a maintenance staff selection unit 115. That is, the second embodiment is different from the first embodiment in that it includes at least a difficulty determination unit 112 and a maintenance staff selection unit 115. In the present embodiment, the selection unit 113 will be described assuming a situation where the calling of a maintenance staff is selected as a method for supporting maintenance work. Note that since the detection unit 111, the selection unit 113, and the execution control unit 114 of the second embodiment are basically the same in configuration and function as the detection unit 101 and the execution control unit 103 of the first embodiment, the description thereof will be omitted here.

[0035] The difficulty determination unit 112 is a means for determining the difficulty level of the maintenance work based on the content of the necessary maintenance work specified by the detection unit 111. In the present embodiment, the difficulty determination unit 112 determines the difficulty level in three levels: high, medium, and low, but is not limited thereto. The difficulty level may be determined in specified levels in advance. The difficulty determination unit 112 determines the difficulty level of the maintenance work based on the estimated required time for the maintenance work, the number of maintenance work steps, or the number and types of spare parts required for the maintenance work. When the difficulty determination unit 112 determines the difficulty level of the maintenance work, it outputs the determined difficulty level to the selection unit 113.

[0036] The selection unit 113 is a means for selecting a maintenance work support method based on the difficulty level of the maintenance work determined by the difficulty determination unit 112. When the difficulty determination unit 112 determines that the difficulty level of the maintenance work is high, the selection unit 113 selects calling a maintenance staff as the maintenance work support method. On the other hand, when the difficulty determination unit 112 determines that the difficulty level of the maintenance work is low, the selection unit 113 selects to display the maintenance work method on the screen of the mobile terminal 210. Note that when the difficulty determination unit 112 does not determine that the difficulty level of the maintenance work is high or the difficulty level of the maintenance work is low, the selection unit 113 selects to connect to a call center that supports the maintenance work. In the present embodiment, the selection unit 113 selects calling a maintenance staff as the maintenance work support method. Next, the execution control unit 114 notifies the maintenance staff selection unit 115 that calling a maintenance staff has been selected.

[0037] When the maintenance staff selection unit 115 receives from the execution control unit 114 that calling a maintenance staff has been selected, the maintenance staff selection unit 115 selects a maintenance staff to be sent to the facility for the maintenance work. For example, the maintenance staff selection unit 115 selects a maintenance staff whose skill level matches the difficulty level of the maintenance work based on the past maintenance work history of the maintenance staff with respect to the difficulty level of the required maintenance work. For example, for a high-difficulty maintenance work that requires replacement of special parts, the maintenance staff selection unit 115 selects a maintenance staff who has performed similar maintenance work in the past. Also, regarding maintenance work that requires urgency, the maintenance staff selection unit 115 may select a maintenance staff to perform the maintenance work in consideration of the current location and schedule of the maintenance staff.

[0038] Next, the operation of the maintenance work support device 110 will be described with reference to the flowchart shown in FIG. 8. The processing according to this flowchart may also be executed based on the program control by the CPU described above.

[0039] As shown in FIG. 8, first, when the detection unit 111 detects the necessity of maintenance work for the facility, it outputs information indicating the detection to the difficulty determination unit 112 (step S201). Next, based on the content of the maintenance work detected by the detection unit 111, the difficulty determination unit 112 determines the difficulty of the maintenance work. If it is determined that the difficulty of the maintenance work is high (S202: YES), the selection unit 113 selects the calling of a maintenance staff as a support method (step S203). On the other hand, if the difficulty determination unit 112 does not determine that the difficulty of the maintenance work is high (S202: NO), the selection unit 113 selects either the display of the maintenance work method or the connection to the call center, and the execution control unit 114 executes the selected maintenance work support method (step S204). Next, when the selection unit 113 selects the calling of a maintenance staff as a support method, the execution control unit 114 notifies the maintenance support service provider that the calling of a maintenance staff has been selected (step S205). Finally, the maintenance staff selection unit 115 selects a maintenance staff suitable for the maintenance work and calls the maintenance staff (step S206). Thus, the maintenance work support device 110 ends the operation of supporting the maintenance work.

[0040] In the maintenance work support device 110 in the second embodiment described above, the maintenance work support method is selected based on the difficulty determined by the difficulty determination unit 112 for the maintenance work. Thereby, for example, when the maintenance work is difficult for an employee in the store, etc., a maintenance staff can be automatically called. Therefore, more appropriate support can be provided according to the necessary maintenance work. Further, in the maintenance work support device 110, the maintenance staff selection unit 115 selects and calls a maintenance staff suitable for the maintenance work. Thereby, since a maintenance staff proficient in the maintenance work performs the maintenance work, the maintenance work can be executed quickly.

[0041] Although the present invention has been described with reference to each embodiment above, the present invention is not limited to the above embodiments. Various changes that can be understood by those skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention.

[0042] For example, although a plurality of operations are described in order in the form of a flowchart, the order of the description does not limit the order in which the plurality of operations are executed. Therefore, when implementing each embodiment, the order of the plurality of operations can be changed as long as it does not interfere with the content. Also, in the second embodiment, after the maintenance work by the maintenance staff is completed, the evaluation of the maintenance staff's work may be received and stored in the storage device 505. Then, the maintenance staff selection unit 115 may select a maintenance staff suitable for future maintenance work in consideration of the received evaluation information.
