<First Embodiment>
FIG. 1 is a schematic configuration diagram of a device maintenance support system 10 according to the first embodiment. The device maintenance support system 10 includes an air conditioning system 12, a user terminal 14, and a server 16 as a device maintenance support device. The air conditioning system 12 and the user terminal 14 can communicate by wireless communication such as short-range wireless communication, for example. Further, the user terminal 14 and the server 16 are connected to be communicable with each other via a communication line 18 such as a LAN (Local Area Network) or the Internet.

  The air conditioning system 12 is provided in a building, for example. The air conditioning system 12 includes one or a plurality of air conditioners 20 that are devices to be maintained. The air conditioner 20 includes an indoor unit 22 and an outdoor unit 24. One air conditioner 20 may include a plurality of indoor units 22. The central control unit 26 performs centralized control of one or a plurality of air conditioners 20 included in the air conditioning system 12. The communication unit 28 includes a short-range wireless communication adapter, for example, and has a function of communicating with the user terminal 14. Or the communication part 28 is comprised, for example from the network adapter etc., and may have the function to communicate directly with the server 16 via the communication line 18. FIG.

  The user terminal 14 is a computer used by a user who maintains the air conditioner 20. In the present embodiment, the user terminal 14 is a portable (mobile) terminal carried by the user, but the user terminal 14 may be a stationary personal computer provided in the vicinity of the air conditioning system 12.

  The communication unit 30 includes, for example, a short-range wireless communication adapter and a network adapter. The communication unit 30 has a function of performing wireless communication between the user terminal 14 and the air conditioning system 12. The communication unit 30 also has a function for the user terminal 14 to communicate with the server 16 via the communication line 18.

  The storage unit 32 includes, for example, a ROM (Read Only Memory) or a RAM (Random Access Memory). A device maintenance support application operable on the user terminal 14 is installed in the storage unit 32. The device maintenance support application is used when the user performs maintenance of the air conditioner 20.

  The display unit 34 includes, for example, a liquid crystal panel. Various display screens are displayed on the display unit 34. The audio output unit 36 includes, for example, a speaker. Various voices are output from the voice output unit 36. The input unit 38 includes a touch panel or buttons. The input unit 38 is used by the user to input instructions or various information to the user terminal 14. The control unit 40 includes, for example, a CPU (Central Processing Unit) or a microcontroller, and controls each unit of the user terminal 14 based on a program stored in the storage unit 32. Further, the control unit 40 executes the device maintenance support application stored in the storage unit 32.

  The user terminal 14 includes a confirmation sensor 42. Alternatively, the confirmation sensor 42 may be externally attached to the user terminal 14. The confirmation sensor 42 may be various types of sensors such as a camera, a microphone, a temperature sensor, a humidity sensor, a wind sensor, an atmospheric pressure sensor, and an illuminance sensor. As will be described in detail later, the confirmation sensor 42 is used to acquire detection data related to the air conditioner 20 in the operating state.

  In maintaining the air conditioner 20, the user first checks the state of the air conditioner 20. Thereby, it is determined whether the air conditioner 20 is operating normally. When it is determined that the air conditioner 20 is not operating normally, the user activates the device maintenance support application. When the device maintenance support application is activated, a status input screen as shown in FIG. On the state input screen, a list L1 of states that can be taken by the air conditioner 20 that is not operating normally, that is, an abnormal state, and a check box C1 corresponding to each state are displayed. The user checks the check box C1 corresponding to the state of the air conditioner 20 confirmed by the user, and presses the transmission button B1. Thereby, the status information indicating the status of the air conditioner 20 is transmitted to the server 16. The state of the air conditioner 20 indicated by the state information does not specify the details of the malfunction of the air conditioner 20, but is the state when the air conditioner 20 that is not operating normally is viewed objectively, or the air conditioner 20 It shows the situation of the place where is installed. As shown in FIG. 2, the state includes, for example, “the wind speed is weak”, “not cool”, “not warmed”, and the like.

  FIG. 3 shows a schematic configuration diagram of the server 16. The server 16 is a computer having a performance that can function as a server. At least the server 16 may be a computer that can exhibit the functions described below.

  The communication unit 50 is composed of, for example, a network adapter. The communication unit 50 has a function of communicating with the user terminal 14 or the air conditioning system 12 via the communication line 18.

  The storage unit 52 includes, for example, a hard disk, ROM, or RAM. The storage unit 52 stores a device maintenance support program for operating each unit of the server 16. Alternatively, the storage unit 52 stores various control data and various processing data. Further, as shown in FIG. 3, a defect information DB (database) 54, an operation content DB 56, a repair work content DB 58, and a confirmation result history DB 60 are defined in the storage unit 52. The defect information DB 54, the operation content DB 56, and the repair work content DB 58 are created in advance by, for example, a skilled maintenance worker based on the past maintenance results and stored in the storage unit 52. The confirmation result history DB 60 stores and stores information related to maintenance work every time maintenance work using the device maintenance support system 10 is performed. Hereinafter, each DB will be described.

  The defect information DB 54 stores each state that can be taken when the air conditioner 20 is not operating normally and the contents of the defect that causes each state in association with each other. FIG. 4 shows an example of the defect information DB 54 in the present embodiment. As shown in FIG. 4, for example, the state “wind velocity is weak” is associated with “filter dirt”, “fan motor deterioration”, and the like, which are fault contents causing the state. Thus, since there may be a plurality of trouble contents that cause one state, in the trouble information DB 54, a plurality of trouble contents can be associated with one state. Although only a part of the defect information DB 54 is shown in FIG. 4, actually, one or more defect contents are defined for many states in the defect information DB 54. In FIG. 4, weight information indicating the weight of the defect content is attached to each defect content, which will be described later.

  In the operation content DB 56, each failure content defined in the failure information DB 54 and the operation content of the air conditioner 20 for making each failure content manifest are stored in association with each other. The content of the operation of the air conditioner 20 for making the content of the malfunction manifest is that the content of the malfunction is reproduced and the user can effectively confirm whether or not the content of the malfunction actually occurs in the air conditioner 20. It is the operation content. In the present embodiment, the operation content DB 56 stores an operation program for automatically operating the air conditioner 20 as the operation content, but the operation content is not limited to this, for example, a character string indicating the operation content, etc. May be stored.

  FIG. 5 shows an example of the operation content DB 56 in the present embodiment. As shown in FIG. 5, for example, an operation program “maximum wind speed operation program” is associated with the defect content “filter contamination”. This is because even if the air conditioner 20 is operated at a low wind speed setting, it is difficult to check the filter dirt, but if it is operated at the maximum wind speed, it is possible to effectively check whether the filter dirt is generated. is there.

  The operation program defined in the operation content DB 56 may be a sequence program that sequentially switches a plurality of operation states. Or the said operation program may operate the air conditioner 20 in the operation state which cannot be performed by normal use of the air conditioner 20. That is, the air conditioner 20 may be operated in a dedicated operation state for specifying the defect content. For example, an operation such as continuing the operation at the maximum output even when the temperature reaches a preset temperature may be performed.

  The operation content DB 56 further indicates that the failure content actually occurs in the air conditioner 20 while the air conditioner 20 is operating according to the operation program for the set of the failure content and the operation program (hereinafter referred to as the operation content DB 56). In order to determine the content of the trouble actually occurring in the air conditioner 20 is described as “true trouble content”), confirmation content that is a content to be confirmed by the user is associated.

  As shown in FIG. 5, in the present embodiment, the confirmation content includes items for confirmation and reference. The confirmation target is information indicating what should be confirmed by the user, that is, “what” of “where” of the air conditioner 20. In the example of FIG. 5, the confirmation target “wind speed of the air conditioner 20” is associated with the defect content “filter contamination” and the operation program “maximum wind speed operation program”. The reference is a value serving as a threshold value for determining that the content of the defect is the true content of the defect when the result of confirming the confirmation target can be acquired as a numerical value. In the example of FIG. 5, the reference “less than XXX [m / sec]” is associated with the confirmation target “wind velocity at the outlet”. This means that when the air conditioner 20 is operating in accordance with the maximum wind speed operation program, if the wind speed at the outlet is less than XXX [m / sec], it can be determined that the filter condition of the air conditioner 20 has occurred. is doing.

  Further, the confirmation content may include items of image data and audio data. The image data indicates the location and state of the air conditioner 20 to be confirmed by the user. The image data may be a still image or a moving image. In particular, when the content to be confirmed by the user is not for measuring the measurement target but for the user to visually check the appearance or internal structure of the air conditioner 20, image data is prepared as the confirmation content. Is preferred. Moreover, audio | voice data shows the audio | voice which the air conditioner 20 which a user should confirm. In particular, when the content to be confirmed by the user is to confirm the sound of the air conditioner 20 during operation, it is preferable that audio data is prepared as the confirmation content.

  Which item value is included in the confirmation content for each set of failure content and operation program may be determined according to the failure content or the operation program. For example, a confirmation target and a reference may be associated with a certain group, only image data may be associated with a certain group, and only audio data may be associated with a certain group.

  In the repair work content DB 58, each trouble content defined in the trouble information DB 54 and repair work contents for each trouble content are stored in association with each other. FIG. 6 shows an example of the repair work content DB 58 in the present embodiment. As illustrated in FIG. 6, for example, the repair content “filter replacement” is associated with the failure content “filter dirt”.

  The confirmation result history DB 60 will be described later.

  The control unit 62 includes, for example, a CPU. The control unit 62 controls each unit of the server 16 according to the device maintenance support program stored in the storage unit 52. As shown in FIG. 3, the control unit 62 includes a defect content selection unit 64, an operation content identification unit 66, a transmission processing unit 68, a confirmation result determination unit 70, a repair work content identification unit 72, and a confirmation result history. It also functions as the analysis unit 74. Hereinafter, each function which the control part 62 exhibits is demonstrated.

  The defect content selection unit 64 is associated with the state indicated by the received state information based on the state information indicating the state of the air conditioner 20 that is not operating normally and the defect information DB 54 received from the user terminal 14. Select the content. For example, if the defect information DB 54 has the contents shown in FIG. 4 and the received state information indicates the state “wind speed is weak”, the defect content selection unit 64 sets the state “wind speed is weak” in the defect information DB 54. Select associated defect details. As shown in FIG. 4, when a plurality of defect contents are associated with the state indicated by the received state information in the defect information DB 54, the defect content selection unit 64 selects one of the plurality of defect contents. Select the content of the defect. At the time of the selection, the defect content selection unit 64 may select the defect content based on the weight information given to each defect content in the defect information DB 54. Specifically, the defect content selection unit 64 may preferentially select a defect content having a large weight indicated by the weight information among the plurality of defect contents.

  Based on the driving content database 56, the driving content specifying unit 66 specifies the driving content (driving program in the present embodiment) associated with the fault content selected by the fault content selecting unit 64. Furthermore, the operation content specifying unit 66 specifies the confirmation content associated with the set of the failure content selected by the failure content selection unit 64 and the specified operation content based on the operation content database 56. For example, when the operation content DB 56 has the contents shown in FIG. 5 and the failure content selection unit 64 selects the failure content “filter dirt”, the operation content specifying unit 66 sets the operation program “maximum wind speed operation program”. Further, as a confirmation content, the confirmation target “wind velocity at the outlet” and the standard “less than XXX [m / sec]” are identified.

  The transmission processing unit 68 transmits, to the user terminal 14, the failure content information indicating the failure content selected by the failure content selection unit 64 and the operation program as the operation content information specified by the operation content specifying unit 66. According to the received defect content information, the defect content selected by the defect content selection unit 64 is displayed on the display unit of the user terminal 14. Thereby, even if the user cannot identify the failure content from the state of the air conditioner 20, the user can grasp the candidate for the failure content occurring in the air conditioner 20. Further, the user uses the user terminal 14 to transfer the operation program received from the server 16 to the air conditioning system 12 by wireless communication. Thereby, the air conditioner 20 can be operated according to the said operation program. As described above, the operation program can effectively confirm whether or not the failure content selected based on the state of the air conditioner 20 actually occurs in the air conditioner 20 (that is, reveal the selected failure content). The air conditioner 20 is operated according to the operation content. Therefore, even if the user does not know the operation content that makes the defect candidate received from the server 16 manifest in the air conditioner 20, by operating the air conditioner 20 according to the operation program transmitted from the server 16, The user can operate the air conditioner 20 by an operation method that makes the candidate for the defect content obvious. Thereby, the user can effectively confirm whether or not the candidate for the defect content is the true defect content.

  In the present embodiment, the transmission processing unit 68 transmits the operation program to the user terminal 14, but the transmission processing unit 68 may transmit the operation program directly to the air conditioning system 12. In the operation content DB 56, when a character string indicating the operation content instead of the operation program is stored as the operation content, the transmission processing unit 68 transmits the character string or the like as the operation content information to the user terminal 14, You may display on the display part 34 of the user terminal 14. FIG. The user can operate the air conditioner 20 according to the operation content when the user operates the air conditioner 20 according to the character string displayed on the display unit 34 or the like.

  In addition, the transmission processing unit 68 transmits confirmation content information indicating the confirmation content specified by the operation content specifying unit 66 to the user terminal 14. Thereby, the confirmation content specified by the operation content specification unit 66 is displayed on the display unit 34 of the user terminal 14. FIG. 7 shows an example of the confirmation content displayed on the display unit 34. The example of FIG. 7 is an example in which, together with the selected defect content “filter contamination”, the confirmation target “wind speed at the outlet” and the criterion “less than XXX [m / sec]” are displayed as the confirmation content. Even if the user does not know where and how to perform confirmation work on the air conditioner 20 in order to confirm the selected defect content, the confirmation content displayed on the display unit 34 is followed. A confirmation operation can be performed on the air conditioner 20. Of course, when image data is specified as the confirmation content, the image data is displayed on the display unit 34, and when audio data is specified, the audio data is output from the audio output unit 36.

  When the user performs a confirmation operation on the air conditioner 20 that is operating according to the operation program transmitted from the server 16, the user can determine whether or not the failure content selected by the failure content selection unit 64 is a true failure content. To check. The user inputs the confirmation result of the confirmation work to the user terminal 14. The user terminal 14 transmits confirmation result information indicating the confirmation result to the server 16.

  For example, as shown in FIG. 7, when a button for allowing the user to input whether or not the criterion included in the confirmation content is satisfied is displayed on the display unit 34 along with the selected defect content and confirmation content, The air velocity at the outlet of the air conditioner 20 is measured using the confirmation sensor 42. If the measurement result is less than XXX [m / sec], the "Yes" button is pressed, and if not, the "No" button Press. When the “Yes” button is pressed, confirmation result information indicating that the defect content selected by the defect content selection unit 64 is the true defect content is transmitted to the server 16. When the “No” button is pressed, Confirmation result information indicating that the defect content selected by the defect content selection unit 64 is not a true defect content is transmitted to the server 16. Of course, the confirmation result information may be transmitted from the user terminal 14 to the server 16 in other manners.

  Alternatively, the user terminal 14 may transmit the detection data acquired by the confirmation sensor 42 to the server 16 instead of the confirmation result information. The detection data is various data according to the confirmation contents. For example, as described above, if the confirmation target is the wind speed, the wind speed data detected by the wind sensor is used. Further, the detection data transmitted to the server 16 may be image data obtained by imaging the air conditioner 20, audio data obtained by recording the operation sound of the air conditioner 20, and the like.

  The confirmation result determination unit 70 determines whether or not the failure content selected by the failure content selection unit 64 is the true failure content based on the confirmation result information received from the user terminal 14 or the detection data. When the confirmation result information is received from the user terminal 14, the confirmation result information itself indicates whether or not the defect content selected by the defect content selection unit 64 is a true defect content. Determines according to the confirmation result information.

  When the detection data is received from the user terminal 14, the confirmation result determination unit 70, based on the confirmation content associated with the driving program identified by the driving content identification unit 66 and the received detection data, It is determined whether or not the defect content selected by 64 is a true defect content. For example, when the content of the operation content DB 56 is the content shown in FIG. 5 and the operation content specifying unit 66 has specified the “maximum wind speed operation program” and has transmitted it to the user terminal 14, the detection received from the user terminal 14 When the data (wind speed data) is less than XXX [m / sec], the confirmation result determination unit 70 determines that the failure content selected by the failure content selection unit 64 is the true failure content, and from the user terminal 14. When the received detection data (wind speed data) is XXX [m / sec] or more, the confirmation result determination unit 70 determines that the failure content selected by the failure content selection unit 64 is not a true failure content. In this case, determination result information indicating the determination result of the confirmation result determination unit 70 may be transmitted to the user terminal 14 by the transmission processing unit 68.

  When it is determined that the defect content selected by the defect content selection unit 64 is not a true defect content, the confirmation result determination unit 70 feeds back the determination result to the defect content selection unit 64. Based on this, the defect content selection unit 64 refers to the defect information DB 54 again and selects other defect contents associated with the state indicated by the received state information. Thereafter, the above-described processing for the other defect contents is repeated.

  Moreover, the confirmation result determination part 70 is the state which the state information received from the user terminal 14 shows, the trouble content selected by the trouble content selection part 64 based on the said state, and the said trouble content is a true trouble content. The confirmation result indicating whether or not is stored in the confirmation result history DB 60 in association with each other. Each time the confirmation result determination unit 70 receives confirmation result information or detection data from the user terminal 14, the confirmation result determination unit 70 stores, in the confirmation result history DB 60, a record that is data in which a state, a defect content, and a confirmation result are associated with each other. Thereby, records are accumulated in the confirmation result history DB 60. FIG. 8 shows an example of the contents of the confirmation result history DB 60.

  The repair work content specifying unit 72 is selected based on the repair work content DB 58 when the confirmation result determination unit 70 determines that the fault content selected by the fault content selection unit 64 is a true fault content. Identify the repair work associated with the defect. For example, when the repair work content DB 58 has the contents shown in FIG. 6 and the trouble content selection unit 64 selects the trouble content “filter dirt”, the repair work content specifying unit 72 displays “filter replacement” as the repair work content. Is specified.

  The failure content information indicating the true failure content determined by the confirmation result determination unit 70 and the repair work content information indicating the repair work content specified by the repair work content specifying unit 72 are transmitted to the user terminal 14 by the transmission processing unit 68. Sent. Then, the true defect content and the repair work content are displayed on the display unit 34 of the user terminal 14. As a result, the user can perform repair work based on the repair work content displayed on the display unit 34 even when the proper repair work content for the true defect content is not known.

  Based on the confirmation result history DB 60, the confirmation result history analysis unit 74 gives weight information to each combination of state and defect content defined in the defect information DB 54. The specific contents of the weight information adding process are as follows. First, the confirmation result history analysis unit 74 selects an attention combination that is a combination of a state to which weight information is to be assigned and a defect content. Next, the confirmation result history analysis unit 74 extracts a record corresponding to the attention combination from the confirmation result history DB 60. For example, when the state “wind velocity is weak” and the failure content “filter contamination” are selected as the attention combination, a record including the state “wind velocity is weak” and the failure content “filter contamination” is extracted from the confirmation result history DB 60. Then, the confirmation result history analysis unit 74 determines weight information for the attention combination based on the number of records in which the confirmation result is “true defect content” among the extracted records. In this embodiment, the ratio of the number of records whose confirmation result is “true defect content” to the number of extracted records is determined as weight information. Thereafter, the confirmation result history analysis unit 74 stores the determined weight information in the defect information DB 54 in association with the attention combination.

  The weight information serves as an index indicating the possibility that the trouble content associated with the weight information is the true trouble content of the air conditioner 20. Accordingly, in the defect information DB 54, when a plurality of defect contents are associated with one state, the defect content selection unit 64 preferentially selects the defect contents having a larger weight indicated by the weight information, It is possible to preferentially select a defect content that is more likely to be a defect. In other words, the user confirms whether or not the failure content that is more likely to be a true failure is the true failure content preferentially. Therefore, the user can specify the true defect content earlier.

  The outline of the device maintenance support system 10 according to the first embodiment is as described above. According to the equipment maintenance support system 10, as a user, only by transmitting state information indicating the state of the air conditioner 20 that is not operating normally to the server 16, the malfunction of the air conditioner 20 causing the state from the server 16.

Including a microphone that detects sound output from the.

  Each time the operation setting of the air conditioner 20 is changed, the building management system 84 receives operation setting information indicating the operation setting from the air conditioning system 12-2. The operation setting information is information indicating, for example, wind speed setting or temperature setting of the air conditioner 20. Then, the building management system 84 determines whether or not the air conditioner 20 is operating normally based on the received operation setting information and the detection data detected by the environmental sensor 88. For example, when the wind speed setting of the air conditioner 20 is “strong”, but the wind sensor as the environmental sensor 88 detects weak wind power that does not match the wind speed setting “strong”, the building management system 84 sets the air conditioning It is determined that the state of the machine 20 is a “wind speed is weak” state. For example, when the temperature setting of the air conditioner 20 is “24 ° C.”, the temperature sensor as the environmental sensor 88 detects a temperature higher than the temperature setting “24 ° C.” by a certain level or more. 84, it determines with the state of the air conditioning machine 20 being a state which does not cool.

  The building management system 84 transmits state information indicating the state of the air conditioner 20 determined in this way to the server 16. The state of the air conditioner 20 may be determined on the server 16 side. In this case, the air conditioning system 12-2 transmits the operation setting information to the server 16, the building management system 84 sequentially transmits the detection data of the environmental sensor 88 to the server 16, and the server 16 receives the received operation setting information and the environmental sensor. The state of the air conditioner 20 is determined based on the 88 detection data.

  When the server 16 receives the status information, the failure content selection unit 64 selects one failure content and the operation content identification unit 66 identifies the operation program, as in the first embodiment.

In the present embodiment, the plurality of confirmation sensors 86 detect a plurality of detection data related to the air conditioner 20 in operation according to the operation program, and the plurality of detection data are transmitted to the server 16.

  The confirmation result determination unit 70 specifies detection data for determining whether or not the defect content selected by the defect content selection unit 64 is the true defect content among the plurality of received detection data. The detection data is specified based on the confirmation content associated with the driving program specified by the driving content specifying unit 66 in the driving content DB 56 (FIG. 5). For example, when the operation content specifying unit 66 specifies the “maximum wind speed operation program”, the confirmation result determination unit 70 specifies detection data from the wind sensor provided at the air outlet of the air conditioner 20. Then, the confirmation result determination unit 70 determines whether or not the failure content selected by the failure content selection unit 64 is true failure content based on the specified detection data. In the above example, when the detection data from the wind sensor is “less than XXX [m / sec]”, it is determined that the failure content selected by the failure content selection unit 64 is the true failure content. At this time, the transmission processing unit 68 may transmit defect content information indicating the determined true defect content to the remote user terminal 82.

  When the true failure content is specified by the confirmation result determination unit 70, the repair work content is specified by the repair work content specification unit 72. Then, the transmission processing unit 68 transmits the defect content information indicating the true defect content and the repair work content information indicating the repair work content to the remote user terminal 82. As a result, the user can grasp the true failure content generated in the air conditioner 20 and the repair work content for repairing the true failure content while staying remotely from the air conditioning system 12-2. .
