The processing unit 230 of the equipment management device 200 associates the operation data (YYY) of the new communication device 30 with the operation data of the outdoor unit 10 before the replacement and the operation data of the outdoor unit 10 after the replacement, and the operation data of the indoor unit 20 before the replacement and the operation data of the indoor unit 20 after the replacement. As a result, when any one of the communication device 30, the outdoor unit 10, and the indoor unit 20 is replaced, the equipment management device 200 stores the operation data of the communication device 30, the outdoor unit 10, and the indoor unit 20 before the replacement. Furthermore, the processing unit 230 integrates the operation data of the outdoor unit 10 before replacement with that of the replaced outdoor unit 10, and integrates the operation data of the indoor unit 20 before replacement with that of the replaced indoor unit 20. The process of integrating the operation data is, for example, a process of summing up the power-on time of the outdoor unit 10 before replacement and the power-on time of the outdoor unit 10 after replacement. This allows the equipment management device 200 to perform a process such as determining whether the power-on time of the outdoor unit 10 and the indoor unit 20 has exceeded their service life using the sum of the power-on time.

[0041] 8 is a diagram showing another example of the repair content registration screen. When replacing the outdoor unit 10, the worker terminal device 410 may display input fields for the model name of the pre-replacement device, the serial number of the pre-replacement device, the model name of the post-replacement device, and the serial number of the post-replacement device. The worker terminal device 410 reads, for example, a code attached to the pre-replacement outdoor unit 10 and a code attached to the post-replacement outdoor unit 10. This allows the worker terminal device 410 to automatically input the model name "XXX" of the pre-replacement device and the serial number "111" of the pre-replacement device, the model name "YYY" of the post-replacement device and the serial number "222" of the post-replacement device into the input fields. In response to receiving the operation in which the registration button has been selected, the worker terminal device 410 transmits work information to the equipment management device 200, the work information including information indicating that the selected equipment is the outdoor unit 10, information indicating the model name of the equipment before replacement, the serial number of the equipment before replacement, the model name of the equipment after replacement, and the serial number of the equipment after replacement, and information indicating that data transfer will be performed automatically.

[0042] FIG. 9 is a diagram showing an example of the transfer of operation data in the embodiment. Assume that the outdoor unit 10 to which the communication device 30 and the indoor unit 20 are connected is replaced with a new outdoor unit 10. In this case, the equipment management device 200 receives, for example, information indicating the model name of the pre-replacement equipment, the serial number of the pre-replacement equipment, the model name of the post-replacement equipment, and the serial number of the post-replacement equipment, and information indicating that data transfer is to be performed automatically. The equipment management device 200 associates the operation data of the pre-replacement outdoor unit 10 with the operation data of the post-replacement outdoor unit 10. For example, the equipment management device 200 can transfer the operation data of the pre-replacement outdoor unit 10, which is not accumulated, such as stop and operation history, operation mode, and set temperature, to the operation data of the post-replacement outdoor unit 10. The equipment management device 200 can also not transfer the operation data of the pre-replacement outdoor unit 10, which is accumulated, such as the power supply time, the number of on / off times, and operation time, from the operation data of the pre-replacement outdoor unit 10 to the operation data of the post-replacement outdoor unit. The equipment management apparatus 200 may store, rather than erase, the operating data that is not to be carried over.

[0043] FIG. 10 is a diagram showing another example of the repair content registration screen. When the repair content is "refrigerant charging", the worker terminal device 410 displays, for example, as shown in FIG. 10, a charging amount input field, a reason input field, a repair date input field, a repair person input field, a photo input field, and a data transfer input field for charging the refrigerant. The worker terminal device 410 accepts, for example, an operation of inputting "1 kg" in the charging amount input field and "automatic" in the data transfer input field, and accepts an operation of selecting the registration button. The worker terminal device 410 transmits work information to the equipment management device 200, including information indicating that the repair content is "refrigerant charging" and that the charging amount input field is "1 kg", and information indicating that data transfer is to be performed automatically.

[0044] FIG. 11 is a diagram showing another example of the transfer of operation data in the embodiment. The equipment management device 200 receives information indicating that the repair content is "refrigerant charging" and that the charging amount input field is "1 kg", and information indicating that the data transfer will be performed automatically. The equipment management device 200 updates the information on the charging amount of refrigerant for the air conditioner 100 associated with the operation data of the communication device 30 using the received information indicating that the charging amount input field is "1 kg". The equipment management device 200 changes the charging amount of refrigerant to, for example, the current charging amount of refrigerant plus 1 kg.

[0045] FIG. 12 is a diagram showing another example of the repair content registration screen. When the repair content is "part replacement", the worker terminal device 410 displays a replacement part input field, a reason input field, a repair date input field, a repair person input field, a photo input field, and a data transfer input field, as shown in FIG. 12, for example. The worker terminal device 410 can accept an operation of inputting "compressor" in the replacement part input field and "automatic" in the data transfer input field, and can accept an operation of selecting the registration button. The worker terminal device 410 transmits work information including information indicating that the repair content is "part replacement" and that the replacement device is "compressor", and information indicating that data transfer is to be performed automatically, to the equipment management device 200.

[0046] FIG. 13 is a diagram showing another example of the transfer of operation data in the embodiment. The equipment management device 200 receives, for example, information indicating that the repair content is "part replacement" and the replacement equipment is "compressor", and information indicating that data transfer is to be performed automatically. The equipment management device 200 resets the operation data to be accumulated among the current operation data of the compressor 12. The accumulated operation data is, for example, data such as the number of times the compressor 12 is turned on and off. The equipment management device 200 does not need to reset the operation data that is not accumulated among the current operation data of the compressor 12. The operation data that is not accumulated is, for example, data such as the operating frequency of the compressor 12. Note that, when the parts of the outdoor unit 10 and the indoor unit 20 are repaired, it is preferable that the equipment management device 200 transfers the accumulated operation data from the parts before repair to the parts after repair without resetting the accumulated operation data of the parts before repair.

[0047] FIG. 14 is a diagram showing another example of the repair content registration screen. For example, as shown in FIG. 14, when the repair content is "cleaning", the worker terminal device 410 displays a cleaning part input field, a reason input field, a repair date input field, a repair person input field, a photo input field, and a data transfer input field. The worker terminal device 410 can accept an operation of inputting "vane" in the cleaning part input field and "no" in the data transfer input field and selecting the registration button. The worker terminal device 410 transmits information indicating that the repair content is "cleaning" and that the cleaning part is "vane", and information indicating that data transfer will not be performed, to the equipment management device 200. When the equipment management device 200 receives information indicating that data transfer will not be performed, the equipment management device 200 does not transfer the operation data for the cleaning part. The equipment management device 200 updates the replacement and repair history information for the vane.

[0048] FIG. 15 is a sequence diagram showing an example of signal transmission and reception in the equipment management system. The air conditioner 100 transmits operation data to the equipment management device 200, and the equipment management device 200 stores the received operation data. For example, when performing work to replace equipment such as the outdoor unit 10, the equipment management device 200 transmits request information to the worker terminal device 410 to prompt the worker to transmit work information, and the worker terminal device 410 transmits the work information to the equipment management device 200. When the worker terminal device 410 receives request information from the equipment management device 200 to prompt the worker to transmit work information, it can start up application software and display an input screen for the work information. This can prevent a situation in which the worker performs work but the work information is not transmitted.

[0049] For example, the worker terminal device 410 may transmit a request to delete operation data related to the equipment or part before replacement to the equipment management device 200. When the equipment management device 200 receives the request to delete, it deletes the operation data related to the equipment or part corresponding to the request.

[0050] The equipment management device 200 transfers the operation data using the work information. In response to the data transfer, the equipment management device 200 notifies the owner terminal device 300 and the maintenance company terminal device 400 of the work. The work notification may include information including, for example, the equipment ID of the equipment on which the worker performed the work, the property ID, and the work content. FIG. 16 is a diagram showing an example of a screen for notifying the owner terminal device 300 or the maintenance company terminal device 400 of the work. The owner terminal device 300 and the maintenance company terminal device 400 can display a screen as shown in FIG. 16 based on the work notification.

[0051] The equipment management device 200 may notify the owner terminal device 300 or the maintenance company terminal device 400 of the operation time of the parts based on the result of the data transfer. FIG. 17 is a diagram showing the relationship between the work history and the operation time. The equipment management device 200 transmits information indicating the work content and information indicating the operation time after the work such as replacing the blower 15, replacing the compressor 12, cleaning the blower 23, etc. after the data transfer to the owner terminal device 300 and the maintenance company terminal device 400. As a result, the owner terminal device 300 or the maintenance company terminal device 400 can check the operation time of the parts after the work by displaying the information shown in FIG. 17.

[0052] The device management device 200 may update the replacement timing of the part based on the operation time of the part after the data transfer. FIG. 18 is a diagram showing the relationship between the part, the work, and the replacement timing. For example, the device management device 200 transmits information including the replacement timing when the fan motor in the blower 15 is not cleaned, the replacement timing when regular cleaning is performed twice a year, and the replacement timing when the fan motor is replaced with a new one to the owner terminal device 300 or the maintenance company terminal device 400. As a result, the device management device 200 provides the owner terminal device 300 with information including the replacement timing of the part, and allows the owner to select the work to be performed on the fan motor. In addition, the maintenance company terminal device 400 can suggest maintenance of the fan motor to the owner.

[0053] When the equipment management device 200 receives operation data from the air conditioner 100 after the work, the equipment management device 200 associates the received operation data with the operation data before the work. The equipment management device 200 integrates the operation data acquired after the work with the operation data that has been transferred. For example, the equipment management device 200 performs processes such as a life diagnosis and a failure diagnosis of the air conditioner 100 based on the operation data transmitted from the air conditioner 100 after the work and the operation data that has been transferred. When the usage time of the outdoor unit 10 exceeds its service life, the equipment management device 200 transmits a life notification to the maintenance contractor terminal device 400. In response to receiving the life notification, the maintenance contractor terminal device 400 transmits a request to refer to the operation data to the equipment management device 200. When the equipment management device 200 receives a request to refer to the operation data from the maintenance contractor terminal device 400, the equipment management device 200 transmits to the maintenance contractor terminal device 400 the operation data that is obtained by integrating the operation data acquired after the work with the operation data that has been transferred. The maintenance contractor terminal device 400 can refer to the operating data and transmit proposal information to the owner's terminal device 300, including proposals for replacing the outdoor unit 10 and the indoor unit 20 of the air conditioner 100, and proposals for maintenance work on the air conditioner 100.

[0054] As described above, the equipment management device 200 of the embodiment includes a data acquisition unit 210 that acquires operation data related to the operation of the air conditioner 100, an acquisition unit 220 that acquires work information related to the work from the worker terminal device 410 operated by the worker who performed the work on the air conditioner 100, and a processing unit 230 that associates the operation data acquired before the work with the operation data acquired after the work based on the work information acquired by the acquisition unit 220. According to the equipment management device 200, the operation data acquired before the work can be automatically associated with the operation data acquired after the work by transmitting the work information from the worker terminal device 410 to the equipment management device 200. As a result, according to the equipment management device 200, for example, when it is necessary to take over the operation data due to the replacement of a part of the communication device 30, the outdoor unit 10, or the indoor unit 20, the burden on the worker to take over the operation data when the air conditioner 100 is replaced or repaired can be reduced. Furthermore, according to the equipment management device 200, the equipment management device 200 automatically transfers the operation data based on the work information, so that it is possible to suppress errors in the transfer of operation data by workers. As described above, the air conditioner 100 includes the communication device 30, the outdoor unit 10, and the indoor unit 20. When any one of the communication device 30, the outdoor unit 10, and the indoor unit 20 is replaced, the equipment management device 200 can store both the operation data acquired before the replacement and the operation data acquired after the replacement in association with the combination of the communication device 30, the outdoor unit 10, and the indoor unit 20 after the replacement.

[0055] For example, when the communication device 30 to which the outdoor unit 10 and the indoor unit 20 are connected is replaced with a new communication device 30, the outdoor unit 10 and the indoor unit 20 to which the communication device 30 before the replacement was connected are connected to the new communication device 30, but there is a possibility that the new communication device 30 may be mistakenly recognized as a combination of the communication device 30, the outdoor unit 10, and the indoor unit 20. In this case, the operation data of the outdoor unit 10 and the indoor unit 20 connected to the communication device 30 before the replacement cannot be taken over. In contrast, according to the device management system of the embodiment, the device management device 200 recognizes that the communication device 30 has been replaced by transmitting work information from the worker terminal device 410 to the device management device 200, and the operation data of the outdoor unit 10 and the indoor unit 20 connected to the communication device 30 before the replacement can be associated with the communication device 30 after the replacement.

[0056] In the embodiment, the work may be replacing a first device included in the air conditioner 100 with a second device. The "device" in the first device and second device is, for example, any of the communication device 30, the outdoor unit 10, and the indoor unit 20. The processing unit 230 can associate the operation data of the first device with the operation data of the second device based on the work information, and perform processing based on the result of integrating the operation data of the first device with the operation data of the second device. For example, the processing unit 230 can perform a life diagnosis by adding the operation time of the first device and the operation time of the second device. For example, the processing unit 230 can create information proposing replacement of the outdoor unit 10, the indoor unit 20, and the communication device 30, or parts, included in the air conditioner 100.

[0057] In the embodiment, the work may be replacing a first part included in a device included in the air conditioner 100 with a second part. The "part" in the first part and second part is an element that constitutes a part of the communication device 30, the outdoor unit 10, or the indoor unit 20, for example, the compressor 12 in the outdoor unit 10. The processing unit 230 can associate the operation data of the first part with the operation data of the second part based on the work information, and perform processing based on the result of integrating the operation data of the first part with the operation data of the second part. For example, the processing unit 230 can perform a life diagnosis by adding the operation time of the compressor 12 before replacement and the operation time of the compressor 12 after replacement. In addition, there are cases where identification information is not given to the parts in the communication device 30, the outdoor unit 10, or the indoor unit 20, but the operation data of the parts can be taken over based on the equipment information of the communication device 30, the outdoor unit 10, or the indoor unit 20 in the work information. For example, operation data for parts is stored in both the control boards of the outdoor unit 10 and the indoor unit 20, and in the equipment management device 200. According to the equipment management system, work information is transmitted from the worker terminal device 410 to the equipment management device 200, so that when replacing parts, the operation data for parts stored in the control boards can be reset, and the operation data for parts stored in the equipment management device 200 can also be reset.

[0058] According to the embodiment, the equipment management device 200 notifies the worker terminal device 410 that work information is to be input. For example, when the equipment management device 200 does not receive work information after a replacement work is performed, the equipment management device 200 can notify the worker terminal device 410. This allows the equipment management device 200 to prevent the worker terminal device 410 from not transmitting the work information to the equipment management device 200. Furthermore, the equipment management device 200 can detect that an unintended replacement or the like has been performed by reliably acquiring the work information and notifying the owner terminal device 300 or the maintenance contractor terminal device 400 based on the work information.

[0059] According to the embodiment, the equipment management device 200 can delete the driving data before the work based on a request received from the worker terminal device 410. This allows the worker to delete unnecessary driving data.

[0060] Although the embodiment of the present disclosure has been described above in detail with reference to the drawings, the specific configuration is not limited to the above-mentioned embodiment, and includes designs within the scope of the present disclosure. The configurations described in the above-mentioned embodiment can be arbitrarily combined. For example, in the embodiment, the air conditioner 100 is described as the target of work, but this is not limited thereto, and the above-mentioned embodiment may be applied if there is a need to associate or transfer operation data before and after work due to work such as equipment replacement, part replacement, repair, or cleaning.
