FIG. 1 shows a schematic 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 with each other by wireless communication such as short distance wireless communication, for example. The user terminal 14 and the server 16 are communicably connected to each other via a communication line 18 such as a LAN (Local Area Network) or the Internet.

The air conditioning system 12 is provided, for example, in a building or the like. The air conditioning system 12 includes one or more air conditioners 20 that are devices to be subjected to maintenance. 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 centrally controls one or more air conditioners 20 included in the air conditioning system 12. The communication unit 28 includes, for example, a short distance wireless communication adapter, and has a function of communicating with the user terminal 14. Alternatively, the communication unit 28 may be configured of, for example, a network adapter, and may have a function of directly communicating with the server 16 via the communication line 18.

The user terminal 14 is a computer used by a user who is a person who performs maintenance of 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 near the air conditioning system 12.

The communication unit 30 includes, for example, a short distance wireless communication adapter, a network adapter, and the like. 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 of the user terminal 14 communicating with the server 16 via the communication line 18.

The storage unit 32 is configured of, for example, a read only memory (ROM) or a random access memory (RAM). In the storage unit 32, a device maintenance support application operable on the user terminal 14 is installed. 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. The display unit 34 displays various display screens. The audio output unit 36 includes, for example, a speaker. The voice output unit 36 outputs various voices. The input unit 38 is configured to include a touch panel or a button. The input unit 38 is used by the user to input an instruction 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. The control unit 40 also executes the device maintenance support application stored in the storage unit 32.

The user terminal 14 also 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, for example, various types of sensors such as a camera, a microphone, a temperature sensor, a humidity sensor, a wind force sensor, an atmospheric pressure sensor, and an illuminance sensor. Although the details will be described later, the confirmation sensor 42 is used to acquire detection data regarding the air conditioner 20 in the operating state.

When maintaining the air conditioner 20, the user first confirms the state of the air conditioner 20. Thus, it is determined whether the air conditioner 20 is operating normally. If 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 state input screen as shown in FIG. 2 is displayed on the display unit 34. In the status input screen, a list L1 of statuses that the air conditioner 20 that is not operating normally, that is, in an abnormal status can be taken, and a check box C1 corresponding to each status are displayed. The user puts a check in the check box C1 corresponding to the state of the air conditioner 20 that he has confirmed, and presses the send button B1. Thus, status information indicating the status of the air conditioner 20 is transmitted to the server 16. Note that the state of the air conditioner 20 indicated by the state information does not identify the content of the problem of the air conditioner 20, but the state when the air conditioner 20 not operating normally is viewed objectively, or the air conditioner 20 Indicates the situation of the place where the As shown in FIG. 2, the state includes, for example, “weak wind speed”, “does not cool”, or “does not warm up”.

FIG. 3 shows a schematic configuration 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 capable of performing the functions described below.

The communication unit 50 includes, 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, a ROM, or a 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, in the storage unit 52, 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. The defect information DB 54, the operation content DB 56, and the repair operation content DB 58 are created in advance by, for example, a skilled maintenance worker or the like based on the past maintenance result and the like, and stored in the storage unit 52. Every time a maintenance operation using the device maintenance support system 10 is performed, the confirmation result history DB 60 accumulates and stores information on the maintenance operation. Each DB will be described below.

In the defect information DB 54, each state that can be taken when the air conditioner 20 is not operating normally and the content of the defect that is the cause of each state are stored in association with each other. The example of defect information DB54 in this embodiment is shown by FIG. As shown in FIG. 4, for example, “filter dirt” and “fan motor deterioration”, which are fault contents causing the state, are associated with the state “low wind speed”. As described above, a plurality of defect contents causing one state may be considered. Therefore, in the defect information DB 54, a plurality of defect contents may be associated with one state. Although only a part of the defect information DB 54 is shown in FIG. 4, actually, in the defect information DB 54, one or more defect contents are defined for a large number of states. In FIG. 4, weight information indicating the weight of the defect content is attached to each content of the defect, which will be described later.

In the operation content DB 56, the content of each defect defined in the defect information DB 54 and the operation content of the air conditioner 20 for eliciting the content of each defect are stored in association with each other. With the operation content of the air conditioner 20 for making the content of the problem apparent, the content of the problem can be reproduced, and the user can effectively confirm whether the content of the problem is actually occurring in the air conditioner 20 It is an operation content to be taken. In the present embodiment, the operation content DB 56 stores an operation program for automatically operating the air conditioner 20 as the operation content. However, the operation content is not limited thereto. For example, a character string indicating the operation content May be stored.

An example of the driving content DB 56 in the present embodiment is shown in FIG. As shown in FIG. 5, for example, the operation program “maximum wind speed operation program” is associated with the content of the failure “filter contamination”. This is because it is difficult to check the filter dirt even if the air conditioner 20 is operated at a low wind speed setting, but if it is operated at the maximum wind speed, it can be effectively checked whether the filter dirt is generated or not. is there.

The driving program defined in the driving content DB 56 may be a sequence program that sequentially switches a plurality of driving states. Alternatively, the operation program may operate the air conditioner 20 in an operation state that can not be performed by normal use of the air conditioner 20. That is, the air conditioner 20 may be operated in the dedicated operation state for specifying the content of the problem. For example, operation may be performed such as continuing the operation at the maximum output even if the preset temperature set in advance is reached.

The operation content DB 56 further indicates that the failure content is actually occurring in the air conditioner 20 while the air conditioner 20 is operating according to the operation program with respect to a set of the problem content and the operation program The confirmation content which is the content to be confirmed by the user in order to determine the content of the failure actually occurring in the air conditioner 20 as “the content of the true failure” is associated.

As shown in FIG. 5, in the present embodiment, the confirmation content includes the items of the confirmation target and the reference. The confirmation target is information indicating a target to be confirmed by the user, that is, “what” of “where” in the air conditioner 20 should be confirmed. In the example of FIG. 5, the check target "the wind speed of the outlet (of the air conditioner 20)" is associated with the content of the problem "filter dirt" and the operation program "maximum wind speed operation program". The reference is a value that serves as a threshold value for determining that the content of the defect is a true defect content 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 check target “wind speed of the outlet”. This means that if the wind speed of the outlet is less than XXX [m / sec] while the air conditioner 20 is operating according to the maximum wind speed operation program, it can be determined that the air conditioner 20 has filter contamination. 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 that the user should check. 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 the one to measure the measurement object but the user visually checks the appearance or internal structure of the air conditioner 20, image data is prepared as the confirmation content. Is preferred. Moreover, audio | voice data show the audio | voice which the air conditioner 20 which a user should confirm shows. 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 voice data be prepared as the confirmation content.

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

In the repair work content DB 58, the content of each defect defined in the defect information DB 54 and the content of repair work for each content of the defect are stored in association with each other. FIG. 6 shows an example of the repair work content DB 58 in the present embodiment. As shown in FIG. 6, for example, the content of the repair work "filter replacement" is associated with the content of the defect "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 in accordance with the device maintenance support program stored in the storage unit 52. Further, as shown in FIG. 3, the control unit 62 includes a defect content selection unit 64, an operation content specification unit 66, a transmission processing unit 68, a confirmation result determination unit 70, a repair operation content specification 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.

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

The driving content specifying unit 66 specifies the driving content (in the present embodiment, the driving program) associated with the defect content selected by the defect content selecting unit 64 based on the driving content database 56. Further, based on the driving content database 56, the driving content specifying unit 66 specifies the confirmation content associated with the combination of the defect content selected by the defect content selecting unit 64 and the specified driving content. For example, when the operation content DB 56 has the content shown in FIG. 5 and the malfunction content selection unit 64 selects the malfunction content “filter dirt”, the operation content specification unit 66 sets the operation program “maximum wind speed operation program”. It identifies, and also specifies the check object "air velocity of outlet" and the reference "less than XXX [m / sec]" as the confirmation content.

The transmission processing unit 68 transmits, to the user terminal 14, fault content information indicating the fault content selected by the fault content selection unit 64 and the driving program as the driving content information identified by the driving content identification unit 66. In accordance with the received defect content information, the display unit of the user terminal 14 displays the defect content selected by the defect content selection unit 64. Thereby, even if the user can not specify the content of the defect from the state of the air conditioner 20, the user can grasp the candidate of the content of the defect occurring in the air conditioner 20. In addition, 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 the fault content selected based on the state of the air conditioner 20 actually occurs in the air conditioner 20 (ie, the selected fault content is manifested The air conditioner 20 is operated according to the operation content. Therefore, even if the user does not know the operation content for causing the air conditioner 20 to reveal the candidate for the defect content received from the server 16, the air conditioner 20 is operated according to the operation program transmitted from the server 16, The user can operate the air conditioner 20 by an operation method for eliciting the content of the defect content. As a result, the user can effectively confirm whether the candidate for the content of the defect is a 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. If the driving content DB 56 stores not a driving program but a character string indicating the driving content as the driving content, the transmission processing unit 68 transmits the character string or the like as the driving content information to the user terminal 14. It may be displayed on the display unit 34 of the user terminal 14. The user can operate the air conditioner 20 according to the operation content by operating the air conditioner 20 according to the character string and the like displayed on the display unit 34.

Further, the transmission processing unit 68 transmits, to the user terminal 14, confirmation content information indicating the confirmation content identified by the driving content identification unit 66. As a result, the confirmation content specified by the driving content specification unit 66 is displayed on the display unit 34 of the user terminal 14. An example of the confirmation content displayed on the display unit 34 is shown in FIG. 7. The example of FIG. 7 is an example in which the check target “air velocity of the outlet” and the reference “less than XXX [m / sec]” are displayed as the check content together with the selected defect content “filter dirt”. Even if the user does not know where and how to check the air conditioner 20 in order to check the content of the selected defect, the confirmation content displayed on the display unit 34 is displayed. A confirmation operation can be performed on the air conditioner 20. Of course, when image data is identified as the confirmation content, the image data is displayed on the display unit 34, and when audio data is identified, the audio data is output from the audio output unit 36.

By the user performing a confirmation operation on the air conditioner 20 operating according to the operation program transmitted from the server 16, the user determines whether the content of the defect selected by the content selection part 64 of the defect is the true content of the defect Make sure. The user inputs the confirmation result of the confirmation operation 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 the display unit 34 displays a button for allowing the user to input whether or not the criteria included in the confirmation content are satisfied, as well as the selected defect content and the confirmation content. Measure the wind speed of the outlet of the air conditioner 20 using the confirmation sensor 42, and press the “Yes” button if the measurement result is less than XXX [m / sec], otherwise “No” button Press. When the "Yes" button is pressed, confirmation result information indicating that the defect content selected by the defect content selecting unit 64 is true defect content is transmitted to the server 16, and when the "No" button is pressed, Confirmation result information indicating that the defect content selected by the defect content selecting 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 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 content. For example, as described above, when the check target is the wind speed, the wind speed data detected by the wind sensor is obtained. The detection data transmitted to the server 16 may be image data obtained by imaging the air conditioner 20 or voice data obtained by recording the operation sound of the air conditioner 20.

The confirmation result determination unit 70 determines, based on the confirmation result information received from the user terminal 14 or the detection data, whether the defect content selected by the defect content selection unit 64 is true defect content. When the confirmation result information is received from the user terminal 14, the confirmation result information itself indicates whether the content of the defect selected by the content selection part 64 of the defect is the true content of the defect. Makes a judgment according to the confirmation result information.

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

If 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 that, the defect content selection unit 64 refers to the defect information DB 54 again, and selects another defect content associated with the state indicated by the received state information. Thereafter, the above-described process for the other fault content is repeated.

In addition, the confirmation result determination unit 70 indicates the state indicated by the state information received from the user terminal 14, the trouble content selected by the trouble content selection unit 64 based on the state, and the trouble content is true trouble content. It associates with the confirmation result indicating whether or not it is stored in the confirmation result history DB 60. Every time confirmation result information or detection data is received 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 the state, the content of the defect, and the confirmation result are associated. Thus, records are accumulated in the confirmation result history DB 60. An example of the contents of the confirmation result history DB 60 is shown in FIG.

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

The transmission processing unit 68 transmits the defect content information indicating the true defect content determined by the confirmation result determination unit 70 and the repair operation content information indicating the repair operation content identified by the repair operation content identification unit 72 to the user terminal 14. Will be sent. Then, the display unit 34 of the user terminal 14 displays the true defect content and the repair operation content. Thereby, the user can perform the repair work based on the repair work content displayed on the display unit 34 even if the user can not know the proper repair work content for the true defect content.

The confirmation result history analysis unit 74 adds weight information to each combination of the state and the content of the problem defined in the failure information DB 54 based on the confirmation result history DB 60. The specific content of the weighting information assignment process is as follows. First, the confirmation result history analysis unit 74 selects an attention combination that is a combination of the state to which weight information is to be added and the content of the failure. Next, the confirmation result history analysis unit 74 extracts a record corresponding to the target combination from the confirmation result history DB 60. For example, when the state “speed of wind is weak” and the content of the defect “filter dirt” are selected as the target combination, a record including the state “speed of wind is weak” and the content of the defect “filter dirt” is extracted from the confirmation result history DB 60. Then, the confirmation result history analysis unit 74 determines weight information for the target combination based on the number of records in which the confirmation result is “true failure content” among the extracted records. In the present embodiment, the ratio of the number of records for which the confirmation result is “true failure 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 is an index indicating the possibility that the failure content associated with the weight information is the true failure content of the air conditioner 20. Therefore, in the defect information DB 54, when a plurality of defect contents are associated with one state, the defect content selecting unit 64 gives priority to the content of the defect indicated by the weight information to be selected preferentially. It is possible to prioritize and select the content of the defect which is more likely to be the defect of. That is, with regard to the fault content that is more likely to be the true fault, the user is firstly confirmed by the user whether or not it is the true fault content. Therefore, the user can identify the true fault content earlier.

The outline of the device maintenance support system 10 according to the first embodiment is as described above. According to the device maintenance support system 10, the user simply sends the status information indicating the status of the air conditioner 20 that is not operating normally to the server 16, and the failure of the air conditioner 20 causing the status from the server 16 The content candidate and the driving content for eliciting the defect content candidate are transmitted. Therefore, even if the user can not predict the content of the problem from the state of the air conditioner 20 or can predict the content of the problem, the user does not know the operation method of the air conditioner 20 for revealing the content of the problem. Also, the air conditioner 20 can be appropriately operated to check the candidate for the content of the defect. Further, since the confirmation content information is transmitted from the server 16, even if the user does not know the content of the confirmation operation, the user can perform the confirmation operation according to the confirmation content. Furthermore, since the repair work content information is transmitted from the server 16 after the true malfunction content of the air conditioner 20 is specified, even if the user does not know the content of the repair work, the repair work content is Repair work of the air conditioner 20 can be performed.

The flow of processing of the device maintenance support system 10 according to the first embodiment will be described below according to the flowchart shown in FIG.

In step S10, the user confirms the state of the air conditioner 20 not operating normally, then starts the device maintenance support application in the user terminal 14, and inputs the confirmed state of the air conditioner 20. The input state information indicating the state of the air conditioner 20 is transmitted from the user terminal 14 to the server 16.

In step S12, the defect content selection unit 64 selects one defect content associated with the state indicated by the state information received from the user terminal 14 based on the defect information DB 54.

In step S14, the driving content identification unit 66 identifies, based on the driving content DB 56, the driving program and the confirmation content associated with the defect content selected in step S12.

In step S16, the transmission processing unit 68 uses the defect content information indicating the defect content selected in step S12, the operation program identified in step S14, and the confirmation content information indicating the confirmation content identified in step S14. It transmits to the terminal 14.

In step S18, the user terminal 14 causes the display unit 34 to display the selected defect content and confirmation content based on the received defect content information and confirmation content information. The user terminal 14 also transfers the received operation program to the air conditioning system 12. Then, the user confirms the air conditioner 20 operating according to the operation program according to the confirmation content, and transmits confirmation result information indicating whether the defect content selected in step S12 is a true defect content to the server 16.

In step S20, the confirmation result determination unit 70 determines, based on the received confirmation result information, whether the defect content selected in step S12 is a true defect content. If it is a true defect content, the process proceeds to step S22.

If the defect is not a true defect, the process returns to step S12, and the defect content selecting unit 64 selects another defect content associated with the state indicated by the state information received from the user terminal 14 in step S12 again. Thereafter, the processes of steps S12 to S20 are repeated until it is determined in step S20 that the contents of the problem are true. As described above, even when a plurality of defect contents are associated with one state in the defect information DB 54, it is possible to specify the true defect contents by repeating the processes of steps S12 to S20.

In step S22, based on the repair work content DB 58, the repair work content specification unit 72 specifies the repair work content associated with the content of the failure specified as the true failure content in step S20.

In step S24, the transmission processing unit 68 transmits, to the user terminal 14, the defect content information indicating the true defect content identified in step S20, and the repair operation content information indicating the repair operation content identified in step S22. . In response thereto, the display unit 34 of the user terminal 14 displays the true defect content and the repair work content, and the user can perform the repair work of the air conditioner 20 based on the displayed repair work content.

The device maintenance support system 80 includes an air conditioning system 12-2, a server 16, a remote user terminal 82, and a building management system 84. The remote user terminal 82 and the building management system 84 each have a communication unit (not shown), and the server 16, the air conditioning system 12-2, the remote user terminal 82, and the building management system 84 They are communicably connected to each other. The configuration content of the server 16 is the same as that of the first embodiment (see FIG. 3). Also, the remote user terminal 82 is a computer used by a user, and is a general computer including portable and stationary. The remote user terminal 82 may have the same configuration as the user terminal 14 in the first embodiment. The remote user terminal 82 may not necessarily be installed near the air conditioning system 12-2. For example, it may be installed in a remote monitoring center that monitors the air conditioning system 12-2.

In the first embodiment, the user confirms the state of the air conditioner 20 not operating normally, and the state information indicating the state is transmitted from the user terminal 14 to the server 16. However, in the second embodiment, the building management The state of the air conditioner 20 is automatically determined based on the detection data regarding the state of the air conditioner 20 detected by the system 84. This eliminates the need for the user to go to the site where the air conditioning system 12-2 is installed in order to check the state of the air conditioner 20. Furthermore, in the second embodiment, while the air conditioner 20 is operating according to the operation program specified by the operation content specification unit 66, whether or not the defect content selected by the defect content selection unit 64 is a true defect content The check result determination unit 70 automatically determines whether or not the data is based on the detection data of the confirmation sensor 86 provided in the air conditioning system 12-2. Thus, in the device maintenance support system 80 according to the second embodiment, the confirmation of the status of the air conditioner 20 from the identification of the true defect content, the identification of the repair content for the true defect content, and the user of the identified information The notification is completely automated.

Similar to the confirmation sensor 42 in the first embodiment, the confirmation sensor 86 provided in the air conditioning system 12-2 has various types such as a camera, a microphone, a temperature sensor, a humidity sensor, a wind sensor, an air pressure sensor, and an illuminance sensor. It may be a sensor. The confirmation sensor 86 is provided with a plurality of various types of sensors at a plurality of locations of the air conditioning system 12-2 so that various parameters regarding the air conditioning system 12-2 in operation can be obtained.

The building management system 84 is a system that manages a building provided with the air conditioning system 12-2. The building management system 84 includes an environmental sensor 88 for detecting detection data related to the condition of the air conditioner 20. The environment sensor 88 is, for example, a wind sensor that detects the wind speed of the wind output by the air conditioner 20, a temperature sensor that detects the temperature of a room in which the air conditioner 20 is provided, a camera that images the air conditioner 20, or the air conditioner 20. Including a microphone that detects the sound output by

The building management system 84 receives operation setting information indicating the operation setting from the air conditioning system 12-2 each time the operation setting of the air conditioner 20 is changed. The operation setting information is, for example, information indicating the wind speed setting or the temperature setting of the air conditioner 20. Then, the building management system 84 determines whether the air conditioner 20 is operating normally based on the received operation setting information and the detection data detected by the environment sensor 88. For example, when the wind speed setting of the air conditioner 20 is "strong" but the wind force sensor as the environment sensor 88 detects weak wind power that does not meet the wind speed setting "strong", the building management system 84 It is determined that the state of the aircraft 20 is "the wind speed is weak". Further, for example, when the temperature setting of the air conditioner 20 is “24 ° C.”, when the temperature sensor as the environment sensor 88 detects a temperature higher than the temperature setting “24 ° C.”, the building management system 84 determines that the state of the air conditioner 20 is "not cool".

The building management system 84 transmits, to the server 16, status information indicating the status of the air conditioner 20 determined in this manner. The determination of the state of the air conditioner 20 may be performed 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 environment sensor 88 to the server 16, and the server 16 receives the received operation setting information and the environment sensor. The state of the air conditioner 20 is determined based on the detection data of 88.

When the server 16 receives the state information, as in the first embodiment, the defect content selecting unit 64 selects one defect content, and the driving content specifying unit 66 specifies the driving program. Then, the transmission processing unit 68 transmits the operation program to the air conditioning system 12-2. At this time, the transmission processing unit 68 may transmit defect content information indicating the selected defect content to the remote user terminal 82. Thereby, the user can grasp that the air conditioner 20 is not operating normally at this time, and confirm whether or not the selected content of the problem occurs in the air conditioner 20 operating according to the operation program. Can.

The air conditioning system 12-2 that has received the operation program from the server 16 operates the air conditioner 20 according to the operation program. Then, in the present embodiment, the plurality of confirmation sensors 86 detect a plurality of detection data regarding 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, among the plurality of received detection data, detection data for determining whether the defect content selected by the defect content selection unit 64 is true defect content. Identification of the detection data is performed 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 specification unit 66 specifies the “maximum wind speed operation program”, the confirmation result determination unit 70 specifies detection data from a wind sensor provided in the outlet of the air conditioner 20. Then, the confirmation result determination unit 70 determines whether the defect content selected by the defect content selection unit 64 is true defect 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 content of the defect selected by the content selection part 64 of the defect is the true content of the defect. At this time, the transmission processing unit 68 may transmit, to the remote user terminal 82, fault content information indicating the determined true fault content.

When the true failure content is specified by the confirmation result judging unit 70, the repair operation content specifying unit 72 specifies the repair operation content. Then, the transmission processing unit 68 transmits, to the remote user terminal 82, fault content information indicating the true fault content and repair work content information indicating the repair work content. As a result, the user can grasp the true trouble content occurring in the air conditioner 20 and the repair work content for repairing the true trouble content while being remote from the air conditioning system 12-2. .
