The operator operates the information processing device 50 to obtain operation data from the outdoor units 60-1 and 60-2 and the indoor units 70-1 to 70-4 via the private network 91 and the air conditioning management device 30. Monitor the operating status of these air conditioners. In addition, the operator inputs operation data to the information processing apparatus 50, whereby the outdoor units 60-1 and 60-2 and the indoor unit 70- are connected from the information processing apparatus 50 via the private network 91 and the air conditioning management apparatus 30. 1 to 70-4 are operated.

The information processing apparatus 50 is a target of access restriction of the database 20, but the air conditioning management apparatus 30 is not a target of access restriction of the database 20. Therefore, the operator can cause the information processing device 50 to acquire the data held in the database 20 of the data holding device 10 via the air conditioning management device 30 by operating the information processing device 50. Further, the operator can edit the data held in the database 20 of the data holding device 10 via the air conditioning management device 30 by operating the information processing device 50.

Note that the information processing apparatus 50 may be a portable information terminal, like the information terminal 80. The information processing apparatus 50 may be a notebook personal computer, for example. Further, the information terminal 80 and the information processing apparatus 50 may hold a software program for displaying and editing data held in the database 20. In this case, the display application unit 17 and the setting application unit 19 may not be provided in the control unit 21.

Next, the operation of the air conditioner maintenance system in the first embodiment will be described. FIG. 5 is a sequence diagram showing an operation procedure of the air conditioner maintenance system according to Embodiment 1 of the present invention.

When an operator operates the information terminal 80 and inputs model information and an abnormal code while looking at the display unit 33 of the air conditioning management device 30, the information terminal 80 holds a data acquisition command including the model information and the abnormal code as data. It transmits to the apparatus 10 (step S101). When receiving the data acquisition command from the information terminal 80, the communication management unit 16 of the data holding device 10 determines whether or not the transmission source information terminal 80 is an access restriction target. If the communication management unit 16 determines that the information terminal 80 is not subject to access restriction, the communication management unit 16 transfers a data acquisition command to the search processing unit 18.

When the search processing unit 18 receives the data acquisition command from the communication management unit 16, the search processing unit 18 reads the model information and the error code from the data acquisition command. Then, the search processing unit 18 searches the model data file 11 using the model information and the abnormal code as keys (step S102), and identifies the service code. Subsequently, the search processing unit 18 reads out service data corresponding to the identified service code from the service data file 13. Thereafter, the search processing unit 18 instructs the display application unit 17 to display the read service data on the information terminal 80. When receiving the service data from the search processing unit 18, the display application unit 17 displays the service data on the display unit 82 of the information terminal 80 via the communication management unit 16 (step S103). The information terminal 80 displays the service data on the display unit 82 (step S104).

In step S102, the search processing unit 18 may read the abnormal data corresponding to the abnormal code from the abnormal data file 12, and attach the read abnormal data to the service data to the display application unit 17. In this case, the display application unit 17 displays the abnormal data and service data on the display unit 82 of the information terminal 80. In this case, the operator can confirm the cause of the abnormality in more detail by referring to the information of the abnormality data displayed on the display unit 82.

Here, the process in step S102 of the search processing unit 18 will be described with reference to FIG. FIG. 6 is a diagram illustrating an example of search processing executed by the search processing unit illustrated in FIG. When the search processing unit 18 receives a data acquisition command including the indoor unit A and the abnormality code EA-0002 from the communication management unit 16, the search processing unit 18 refers to the model data file 11 and associates the indoor unit A with the abnormal code EA-0002. Read service code SB-0003. Then, the search processing unit 18 reads the service data of the service code SB-0003 from the service data file SB. At this time, the search processing unit 18 may pass the abnormal data together with the service data to the display application unit 17. In this case, the operator can understand from the information of the abnormal data displayed on the display unit 82 that the “temperature abnormality” is the cause of the abnormality.

In this way, the operator can acquire the abnormal data and the service data from the database 20 using the model information and the abnormal code as keys by operating the information terminal 80 and inputting the model information and the abnormal code. Therefore, the operator can efficiently acquire maintenance information including the cause of the abnormality and a countermeasure for the air conditioner in which the abnormality has occurred.

Further, the operator may acquire service data from the data holding device 10 through the information processing device 50 and the air conditioning management device 30 by operating the information processing device 50. Specifically, when the worker inputs model information and an abnormality code to the information processing device 50, the information processing device 50 transmits a data acquisition command to the data holding device 10 via the air conditioning management device 30. Since the air conditioning management device 30 is not subject to the access restriction of the database 20, the data holding device 10 receives the data acquisition command received from the air conditioning management device 30. When the data holding device 10 acquires the service data from the database 20 based on the data acquisition command, the data holding device 10 displays the service data on the display unit 33 of the air conditioning management device 30. The air conditioning management device 30 transfers the service data displayed on the display unit 33 to the information processing device 50 and causes the display unit 52 to display the service data.

In this case, even if the information processing device 50 that is not connected to the network 90 is a device in which access to the database 20 is restricted, the worker operates the information processing device 50 and passes through the air conditioning management device 30. Information regarding maintenance can be acquired from the database 20. As a result, the convenience of maintenance for the operator is improved.

Next, a case where the operator operates the information terminal 80 to edit data held in the database 20 will be described. FIG. 7 is a sequence diagram showing an operation procedure when editing data held in a database in the air conditioner maintenance system according to Embodiment 1 of the present invention.

When the control unit 21 of the data holding device 10 receives the display request signal, the display application unit 17 displays the service data file 13 on the display unit 82 of the information terminal 80.

When an operator inputs an instruction to rewrite service contents to the information terminal 80 while viewing the service data file 13 displayed on the display unit 82, the information terminal 80 sends a data setting command including information on the rewrite instruction to the data holding device. 10 (step S201). When the control unit 21 of the data holding device 10 receives the data setting command, the setting application unit 19 edits the service data file 13 according to the rewrite instruction included in the data setting command (step S202). Subsequently, the display application unit 17 displays the edited service data file 13 on the display unit 82 of the information terminal 80 (step S203). The information terminal 80 displays the edited service data file 13 on the display unit 82 (step S204).

In this way, the operator can edit the data held in the database 20 of the data holding device 10 by operating the information terminal 80. The operator may edit the data held in the database 20 of the data holding device 10 via the air conditioning management device 30 by operating the information processing device 50.

You can refer to the abnormal data that occurred. An operator may operate the information processing device 50 and acquire maintenance information using the property data file 14 held in the database 20 of the data holding device 10a via the air conditioning management device 30.

In the second embodiment, the control unit 21 stores the property data file 14 that holds the history data including the model information, the model environment of the model information, and the abnormality code of the abnormality that has occurred in the model in the building unit and the floor unit. By using it as maintenance information, it is possible to present abnormal data generated in an environment similar to an air conditioner to be maintained to an operator. As a result, the worker can examine the countermeasure method with reference to the past information of the abnormality occurring in the environment closer to the air conditioner in which the abnormality has occurred.

Embodiment 3 FIG.
In the third embodiment, the data holding device stores a work history file that holds work history data including history information at the time of occurrence of an abnormality of an air conditioner in which an abnormality has occurred in the past. Is made available to the operator as maintenance information.

The configuration of the air conditioner maintenance system in the third embodiment will be described. In the third embodiment, detailed description of the same configuration as in the first and second embodiments is omitted. FIG. 11 is a block diagram showing an example of the configuration of the data holding device according to Embodiment 3 of the present invention.

As shown in FIG. 11, in the data holding device 10b according to the third embodiment, the database 20 holds a work history file 15 in addition to the information shown in FIG. The work history file 15 stores the latest information related to the work history of monitoring the operations and operations at the time of occurrence of a past abnormality for each air conditioner.

FIG. 12 is a diagram showing a configuration example of a work history file held by the database shown in FIG. The work history file 15 has a plurality of work history data for each property such as a building unit and a floor unit. The work history data includes a property name, a work date, a work history, and arbitrary information. The work history is information on the history of operation when an abnormality occurs in the air conditioner. Specifically, the work history includes model information, an operation when the air conditioner of the model information has an abnormality, and information on the time of each operation. In the arbitrary information, work information when an abnormality is dealt with is registered. When registering work history data, the worker can arbitrarily enter work information in the optional information column.

The work history file 15 is configured to acquire the work history of the air conditioner in which an abnormality has occurred, using the property name as a key. The work history data can also be searched using the model information of the air conditioner to be maintained as a key. If the operator does not know the cause of the failure of the air conditioner to be maintained and the corrective action from the model information and the error code alone, the operator operates the information terminal 80 and searches the work history file 15 to obtain information related to maintenance. As a work history can be obtained.

As a method for registering work history data in the work history file 15, a method in which the air conditioning management device 30 automatically uploads and a method in which the operator operates the information terminal 80 or the information processing device 50 to register are considered.

An example of how to upload automatically will be explained. The operation history control unit 35 stores operation data and operation data in the storage unit 36 at regular intervals. When an abnormality occurs in the air conditioner connected to the air conditioning management device 30, the operation history control unit 35 reads operation data and operation data for a predetermined time before and after the occurrence of the abnormality, and stores model information in these data. Create work history data including. Further, the operation history control unit 35 attaches information on which building and which floor the target air conditioner is installed to the work history data. Then, the operation history control unit 35 transmits the created work history data to the data holding device 10b. The control unit 21 of the data holding device 10b sorts the work history data received from the air conditioning management device 30 for each building and each floor and stores it in the work history file 15. In this way, when an abnormality occurs in the air conditioner, the air conditioning management device 30 creates work history data, and the work history file 15 is automatically updated.

When the worker registers the work history data in the data holding device 10, the information processing device 50 may be operated to input an instruction to transmit the work history data created by the air conditioning management device 30 to the data holding device 10b. The worker may edit the work history data already held in the work history file 15 by operating the information terminal 80 or the information processing apparatus 50. For example, the worker may operate the information terminal 80 to register the work information in the optional information column.

The search processing unit 18 of the data holding device 10 searches the work history file 15 based on the model information to acquire a property where the same model as the maintenance target is installed. The search processing unit 18 can acquire work history data associated with the model information from the work history file 15 based on the model information, for example.

The setting application unit 19 writes the model data file 11, the abnormal data file 12, the service data file 13, the property data file 14, and the work history file 15 based on the data setting command received from the air conditioning management device 30 and the information terminal 80. Change.

Next, the operation procedure of the air conditioner maintenance system in the third embodiment will be described. FIG. 13 is a sequence diagram showing an operation procedure of the air conditioner maintenance system according to Embodiment 3 of the present invention. Here, description regarding access restriction is omitted.

When the operator operates the information terminal 80 and inputs the model information of the air conditioner to be maintained, the information terminal 80 transmits a search request command including the model information to the data holding device 10b (step S401). When the control unit 21 of the data holding device 10b receives the search request command, the search processing unit 18 searches the work history file 15 using the model information as a key (step S402). Then, when there is work history data that matches the search condition, the search processing unit 18 passes the work history data to the display application unit 17. The display application unit 17 displays the received work history data on the display unit 82 of the information terminal 80 (step S403). The information terminal 80 displays the work history data on the display unit 82 (step S404).

In this manner, the operator operates the information terminal 80 and uses the work history file 15 held in the database 20 of the data holding device 10b to detect abnormalities in the past in the air conditioner of the same model as the maintenance target air conditioner. You can refer to the history when this occurred. As a result, the operator can grasp the phenomenon that will occur in the future in the air conditioner to be maintained, and can cope with it in advance. Further, if the work information is registered in the arbitrary information of the work history data, the worker can refer to what measures have been taken for the abnormality. The operator may operate the information processing apparatus 50 and use the work history file 15 held in the database 20 of the data holding apparatus 10b via the air conditioning management apparatus 30 to acquire maintenance information.

Recently, entry into buildings such as buildings is often strictly controlled, and air conditioners installed in such buildings are also placed in environments where communication connections are strictly controlled. In maintenance of an air conditioner installed in such an environment, it may be difficult in terms of security for an operator to connect an information processing apparatus or information terminal for maintenance to the air conditioning management apparatus via a network. Therefore, it is difficult for an operator to collect maintenance information by collating information during maintenance with the state of the air conditioning management device.

In contrast, in the third embodiment, the control unit 21 of the data holding device 10b sorts the received work history data in units of buildings and floors every time work history data is received from the air conditioning management device 30. And stored in the work history file 15 held by the database 20. Since the data holding device 10b does not restrict access to the air conditioning management device 30, the air conditioning management device 30 stores the work history data created every time an abnormality occurs in the air conditioner managed by the data holding device 10b. 10b can be sequentially registered. Therefore, the data holding device 10b can easily accumulate the latest work history information and can automatically update the maintenance information.

In the third embodiment, the control unit 21 holds work history data including model information and history information of operations when an abnormality occurs in the model of the model information in the unit of building and floor. By using the file 15 as maintenance information, the operator can refer to the history when an abnormality has occurred in the past in the same type of air conditioner as the maintenance target air conditioner. As a result, the operator can grasp the phenomenon that will occur in the future in the air conditioner to be maintained, and can cope with it in advance.

In the third embodiment, the case where the work history file 15 is provided in the data holding device 10a described in the second embodiment has been described. However, the work history file 15 is added to the data holding device 10 described in the first embodiment. It may be provided.
