  Next, the configuration of the data holding device 10 will be described. As shown in FIG. 1, the data holding apparatus 10 includes a database 20, a communication management unit 16, and a control unit 21. The database 20 is configured by, for example, an HDD (Hard Disk Drive). The database 20 may be a non-volatile memory such as a flash memory. The database 20 holds a model data file 11, an abnormal data file 12, and a service data file 13. These files store, for each model, information on abnormalities that have occurred in the past and how to handle them. That is, the information on the latest abnormality is sequentially registered in the database 20.

  The abnormal data file 12 is a file in which a plurality of abnormal data, which are data relating to an abnormality occurring in the air conditioner, are listed. The service data file 13 is a file in which a plurality of service data, which is data including a method for dealing with an abnormality, is listed. The model data file 11 is a file that associates abnormal data and service data using the model information of the air conditioner as a key.

  FIG. 2 is a view showing a configuration example of a model data file held by the database shown in FIG. As shown in FIG. 2, the model data file 11 associates and holds model information, an abnormality code, and a service code which is an identifier different for each service data. The model data is data including model information, an error code, and a service code for each model. In the example illustrated in FIG. 2, the model data of the indoor unit A includes a plurality of abnormality codes of EA-001 to 7999 and a plurality of service codes of SA0000, SA0001, and SA0003. Focusing on one anomaly code, a plurality of service codes are associated with one anomaly code in the model data. Also, focusing on one service code, a plurality of anomaly codes are associated with one service code. This is because a plurality of causes can be considered with respect to one abnormality, and there can be a way of coping with each of the plurality of causes.

  If the occurrence frequency is calculated statistically among a plurality of causes for one abnormality, presenting the operator with a countermeasure for the cause with the highest occurrence frequency can reduce the time required for maintenance. Therefore, in the model data file 11, when a plurality of service codes can be considered for one abnormal code, at least one service code having a high frequency of use may be associated. Further, the number of service codes to be associated is not limited to one, and may be two or more numbers determined in advance in descending order of usage frequency.

  Although the case has been described in which the number of service codes associated with one abnormal code is narrowed down by use frequency, when multiple abnormal codes are associated with one service code, they are associated with one service code. The number of anomaly codes may be narrowed by frequency of use. Although the case where the number of service codes associated with the abnormal code is determined by the frequency of use has been described, the determination method is not limited to the frequency of use of the service code. Further, the model data may hold the abnormality code and the service code in one-to-one correspondence.

  FIG. 3 is a diagram showing an exemplary configuration of an abnormal data file held by the database shown in FIG. As shown in FIG. 3, the abnormal data file 12 has a configuration in which a plurality of abnormal data are listed. The abnormal data includes information of an abnormal code, detailed information of the abnormal content, a cause of the abnormal and a coping method for the cause. The abnormal data file 12 is configured such that information necessary for maintenance can be obtained using the abnormal code as a key.

The abnormality data file 12 is held in the database 20 for each type of air conditioner such as an outdoor unit, an indoor unit, an air conditioner, a ventilator, and a hot water supply device.

  FIG. 4 is a diagram showing an example of a configuration of service information held by the database shown in FIG. The service data file 13 has a configuration in which a plurality of service data are listed. The service data includes a service code, detailed information at the time of occurrence of an abnormality, information on the cause for which the service is required, and a solution to the cause. The service data file 13 is configured such that information on necessary services can be obtained using the service code as a key. The service data file 13 shown in FIG. 4 is a service data file of the indoor unit A. The service data file 13 is held in the database 20 for each type of air conditioner such as an outdoor unit, an indoor unit, an air conditioner, a ventilator, and a hot water supply device.

The communication management unit 16 has a function of access restriction of the database 20. An example of access restriction will be described. The communication management unit 16 reads the device identifier of the transmission source included in the received data. The communication management unit 16 determines whether the device identifier of the transmission source matches the device identifier registered in advance. When the device identifier of the transmission source matches the registered device identifier, the communication management unit 16 authenticates the device to which the access is permitted, and transfers the received data to the control unit 21. On the other hand, when the device identifier of the transmission source and the registered device identifier do not match, the communication management unit 16 recognizes the transmission source as a target device for access restriction, and does not transfer the received data to the control unit 21.

  When the communication management unit 16 receives, from the air conditioning management device 30 and the information terminal 80, a data acquisition command requesting data stored in the database 20, the communication management unit 16 authenticates the transmission source and transfers the data acquisition command to the control unit 21. When the communication management unit 16 receives data from the control unit 21 as a response to the data acquisition command, the communication management unit 16 sends the data back to the transmission source. Further, when the communication management unit 16 receives a data setting instruction including a data rewriting instruction held by the database 20 from the air conditioning management device 30 and the information terminal 80, the communication management unit 16 authenticates the transmission source, and transmits the data setting instruction to the control unit 21. Forward.

  The device identifiers of the air conditioning management device 30 and the information terminal 80 may be registered in advance in the memory of the control unit 21 or may be registered in a memory provided in advance in the communication management unit 16. Further, instead of the device identifier, a user ID and password predetermined for each worker may be used for authentication of access restriction release. In addition, the control unit 21 may have a function of access restriction.

  The control unit 21 edits the contents of each data, the search processing unit 18 for searching appropriate data from the data held by the database 20, the display application unit 17 for providing the information terminal 80 with a tool for displaying the searched data, and And a setting application unit 19 for providing the information terminal 80 with the The control unit 21 has a memory for storing a program, and a CPU for executing processing in accordance with the program. When the CPU executes the program, the display application unit 17, the search processing unit 18, and the setting application unit 19 are configured in the data holding apparatus 10.

  The search processing unit 18 acquires appropriate data from the model data file 11, the abnormal data file 12, and the service data file 13 based on the data acquisition instruction received from the air conditioning management device 30 and the information terminal 80. For example, the search processing unit 18 identifies an abnormality code from the model data file 11 based on the model information included in the data acquisition command, and the abnormal content, the cause of the abnormality, and the countermeasure for the abnormality associated with the abnormality code. Acquired from the abnormal data file 12 Further, the search processing unit 18 identifies the service code from the model data file 11 based on the model information included in the data acquisition command, and the detailed information at the time of the abnormality occurrence associated with the service code and the cause of the anomaly The content of the service and the coping method may be acquired from the service data file 13. Furthermore, if the data acquisition command includes the model information and the abnormal code, the search processing unit 18 identifies the service code by referring to the model data file 11 using the model information and the abnormal code as a key, and identifies the specified service code. Service data corresponding to may be acquired from the service data file 13.

  When the display application unit 17 receives a data acquisition instruction from the information terminal 80 via the communication management unit 16, the display application unit 17 causes the display unit 82 of the information terminal 80 to display the data searched by the search processing unit 18 based on the data acquisition instruction. When the display application unit 17 receives a data acquisition command from the air conditioning management device 30 via the communication management unit 16, the display application unit 17 displays the data retrieved by the search processing unit 18 based on the data acquisition command in the display unit 33 of the air conditioning management device 30.

  When the setting application unit 19 receives a data setting instruction from the information terminal 80 via the communication management unit 16, the setting application unit 19 is related among the model data file 11, the abnormal data file 12, and the service data file 13 based on the data setting instruction. Rewrite the file contents. When the setting application unit 19 receives a data setting instruction from the air conditioning management device 30 via the communication management unit 16, the setting application unit 19 selects one of the model data file 11, the abnormal data file 12 and the service data file 13 based on the data setting instruction. , Rewrite the contents of the associated file.

  Although the display application unit 17, the setting application unit 19, and the search processing unit 18 are described as being configured by the CPU executing a program with reference to FIG. 1, a dedicated circuit for executing these functions is described. It may be configured by hardware such as a device. The search processing unit 18 may be configured by the CPU executing an independent application software program stored in the data holding device 10. In this case, this application software program may be stored in advance in the data holding apparatus 10. Similarly, the display application unit 17 may be configured such that the CPU executes an independent application software program stored in the data holding device 10. In this case, the application software program may be stored in advance in the data holding device 10.

  The information terminal 80 includes a communication management unit 81, a display unit 82, an input unit 83, and a control unit 84 that controls the configuration of these. Control unit 84 has a memory for storing a program and a CPU for executing processing in accordance with the program. The information terminal 80 is, for example, a portable information terminal such as a smartphone and a tablet. When transmitting the data acquisition instruction and the data setting instruction to the data holding apparatus 10 via the communication management unit 81, the control unit 84 attaches the device identifier of the information terminal 80 to these instructions and transmits it.

  The control unit 84 has a function of causing the display unit 82 to display data held by the database 20 of the data holding device 10 via the display application unit 17 and the search processing unit 18. The control unit 84 also has a function of editing data held by the database 20 of the data holding device 10 via the setting application unit 19. Therefore, the worker operates the information terminal 80, and the data held by the database 20 can be rewritten via the setting application unit 19. In addition, the worker can operate the information terminal 80 to cause the display unit 82 to display data held by the database 20 via the display application unit 17. The control unit 84 does not have to hold a software program for displaying and editing data held by the database 20. For example, the control unit 84 may hold a browser. In this case, the process of causing the display application unit 17 to display data on the display unit 82 can be considered to be equivalent to a process of transmitting data to be displayed on the browser by the control unit 21 to the information terminal 80.

The operator operates the information processing device 50 to acquire 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 condition of these air conditioners. In addition, the worker inputs the operation data to the information processing device 50 to allow the outdoor unit 60-1, 60-2 and the indoor unit 70 to pass from the information processing device 50 through the private network 91 and the air conditioning management device 30. Operate 1 to 70-4.

  The information processing device 50 is an object of access restriction of the database 20, but the air conditioning management device 30 is not an object of access restriction of the database 20. Therefore, the worker can operate the information processing apparatus 50 to cause the information processing apparatus 50 to acquire data held by the database 20 of the data holding apparatus 10 via the air conditioning management apparatus 30. Further, the worker can operate the information processing apparatus 50 and edit the data held by the database 20 of the data holding apparatus 10 via the air conditioning management apparatus 30.

  The information processing apparatus 50 may be a portable information terminal, as in the case of the information terminal 80. The information processing apparatus 50 may be, for example, a laptop personal computer. Further, the information terminal 80 and the information processing device 50 may hold a software program for displaying and editing data held by 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 according to 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 the operator operates the information terminal 80 and inputs model information and an abnormality code while looking at the display unit 33 of the air conditioning management device 30, the information terminal 80 holds data acquisition command including the model information and the abnormality code. 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 the transmission source information terminal 80 is a target of access restriction. When the communication management unit 16 determines that the information terminal 80 is not a target of access restriction, the communication management unit 16 transfers a data acquisition command to the search processing unit 18.

  When receiving the data acquisition instruction from the communication management unit 16, the search processing unit 18 reads out the model information and the abnormality code from the data acquisition instruction. Then, the search processing unit 18 searches the model data file 11 using the model information and the abnormality code as keys (step S102), and specifies the service code. Subsequently, the search processing unit 18 reads service data corresponding to the specified 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 the display application unit 17 receives the service data from the search processing unit 18, the display application unit 17 causes the display unit 82 of the information terminal 80 to display the service data 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 out the abnormal data corresponding to the abnormal code from the abnormal data file 12, attach the read out abnormal data to the service data, and pass it to the display application unit 17. In this case, the display application unit 17 causes the display unit 82 of the information terminal 80 to display abnormal data and service data. In this case, the worker can confirm the cause of the abnormality occurrence in more detail by referring to the information of the abnormal data displayed by 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 showing an example of search processing executed by the search processing unit shown 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 is associated with the indoor unit A and the abnormality code EA-0002. The service code SB-0003 is read. Then, the search processing unit 18 reads out 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 to the display application unit 17 together with the service data. In this case, it is known from the information of the abnormal data displayed by the display unit 82 that the “temperature abnormality” is the cause of the abnormal occurrence.

  In this manner, the worker operates the information terminal 80 to input the model information and the abnormality code, and thereby can acquire the abnormal data and the service data from the database 20 using the model information and the abnormality code as a key. Therefore, the worker can efficiently obtain maintenance information including the cause of the abnormality and the countermeasure method for the air conditioner in which the abnormality has occurred.

  Further, the worker may operate the information processing device 50 to acquire service data from the data holding device 10 via the information processing device 50 and the air conditioning management device 30. Specifically, when the worker inputs model information and an abnormality code into the information processing apparatus 50, the information processing apparatus 50 transmits a data acquisition command to the data holding apparatus 10 via the air conditioning management apparatus 30. Since the air conditioning management device 30 does not receive 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. Then, when the data holding device 10 acquires service data from the database 20 based on the data acquisition command, the data holding device 10 causes the display unit 33 of the air conditioning management device 30 to display the service data. 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 data.

  In this case, even if the information processing device 50 not connected to the network 90 is a device whose access to the database 20 is restricted, the worker operates the information processing device 50 and passes the air conditioning management device 30. , Information on maintenance can be obtained from the database 20. As a result, the convenience of maintenance of the worker is improved.

  Next, a case where a worker operates the information terminal 80 to edit data held by the database 20 will be described. FIG. 7 is a sequence diagram showing an operation procedure in the case of editing data held by the database in the air conditioner maintenance system according to Embodiment 1 of the present invention. Here, it is assumed that the file to be edited is the service data file 13. Also, the description on the access restriction is omitted.

  When an operator operates the information terminal 80 to input an instruction to request display of the service data file 13, the information terminal 80 generates a display request signal to request display of the service data file 13 as a data holding device. Send to 10 When the control unit 21 of the data holding device 10 receives the display request signal, the display application unit 17 causes the display unit 82 of the information terminal 80 to display the service data file 13.

  When an operator inputs an instruction to rewrite the content of the service to the information terminal 80 while looking at the service data file 13 displayed on the display unit 82, the information terminal 80 transmits a data setting instruction including information on the rewriting instruction to the data holding device 10 (step S201). When the control unit 21 of the data holding apparatus 10 receives the data setting instruction, the setting application unit 19 edits the service data file 13 according to the rewriting instruction included in the data setting instruction (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 manner, the worker can manipulate the information terminal 80 to edit the data held by the database 20 of the data holding device 10. The worker may operate the information processing device 50 and edit the data held by the database 20 of the data holding device 10 via the air conditioning management device 30.

  The air conditioner maintenance system 100 according to the first embodiment includes the air conditioning management device 30 for managing a plurality of air conditioners and the data holding device 10, and the data holding device 10 is provided for each abnormality occurring in the plurality of air conditioners.

The control unit 21 sends data acquisition commands for maintenance target air conditioners to the information terminal 80. When received from network via network 90, model information and error code included in data acquisition command The identify service data by searching the model data file 11 as a key, and displays the information terminal 80 reads the service data specified from the service data file 13.

  In the first embodiment, the data holding device 10 reads maintenance information related to an air conditioner to be maintained from the database 20 storing maintenance information including abnormal data and service data, and provides it to the information terminal 80 of the worker. . Therefore, the worker can easily obtain the maintenance information, and can quickly reach the cause of the abnormality of the air conditioner which requires maintenance and a countermeasure. As a result, the maintenance of the air conditioner can be made more efficient.

  Further, in the first embodiment, the information processing device 50 which can not access the data holding device 10 acquires information on maintenance from the data holding device 10 via the air conditioning management device 30. Since the worker can operate the information processing apparatus 50 from the data holding apparatus 10 which is difficult to connect for security and obtain maintenance information, the convenience of maintenance is improved.

The worker can refer to the abnormality information included in the history data matching the search condition.

  As a method of registering history data in the property data file 14, a method in which the air conditioning management device 30 automatically uploads, and a method in which a worker operates and registers the information terminal 80 or the information processing device 50 can be considered. Further, the worker may edit the history data already stored in the property data file 14 by operating the information terminal 80 or the information processing apparatus 50. As an example of a method of automatically uploading, a method may be considered in which the operation history control unit 35 reads out the operation history of the storage unit 36 and registers the operation history at a property name set in advance.

  The search processing unit 18 of the data holding device 10 searches the property data file 14 based on the model information to acquire the property in which the same model as the maintenance target is installed. Further, the search processing unit 18 acquires, for example, the model information and the device configuration of the air conditioner installed in the property from the property data file 14 based on the property name, and the model data file 11 based on the acquired model information. Can be searched to obtain abnormal data and service data associated with model information.

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

  Next, the operation procedure of the air conditioner maintenance system according to the second embodiment will be described. FIG. 10 is a sequence diagram showing an operation procedure of the air conditioner maintenance system in the second embodiment of the present invention. Here, the description on the access restriction is omitted.

  When the operator operates the information terminal 80 to input the environment information and model information of the air conditioner to be maintained, the information terminal 80 transmits a search request command including the environment information and model information to the data holding device 10a ( Step S301). When the control unit 21 of the data holding device 10a receives the search request command, the search processing unit 18 searches the property data file 14 using the environment information and the model information as keys (step S302). Then, when there is history data matching the search condition, the search processing unit 18 reads out the abnormal code included in the history data. Thereafter, the search processing unit 18 reads out the abnormal data corresponding to the abnormal code from the abnormal data file 12, and passes the read out abnormal data to the display application unit 17. The display application unit 17 causes the display unit 82 of the information terminal 80 to display the received abnormal data (step S303). The information terminal 80 displays the abnormal data on the display unit 82 (step S304).

  In this way, the operator operates the information terminal 80 and uses the property data file 14 held by the database 20 of the data holding device 10a in an environment that approximates the environment information such as the equipment configuration of the air conditioner The anomaly data of the anomaly that has occurred can be referred to.

By using it as maintenance information, it is possible to present an operator with abnormal data generated in an environment similar to an air conditioner to be maintained. As a result, the worker can consider the coping method with reference to the past information of the abnormality that has occurred in the environment closer to the air conditioner in which the abnormality has occurred.

Third Embodiment
In the third embodiment, the data holding device stores a work history file in which work history data including information of a history of abnormality occurrence of an air conditioner in which abnormality has occurred in the past is stored in units of floors and in units of buildings. Is made available to workers as maintenance information.

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

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

  FIG. 12 is a view showing an example of the configuration of a work history file held by the database shown in FIG. The work history file 15 has a plurality of work history data in units of property such as a building unit and a floor unit. The work history data includes a property name, a work date and time, a work history, and arbitrary information. The work history is information on the history of the operation when the air conditioner has an abnormality. 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. As the arbitrary information, work information when dealing with an abnormality is registered. When registering work history data, the worker can arbitrarily input work information in the field of arbitrary information.

  The work history file 15 is configured to be able to acquire the work history of the air conditioner in which the abnormality has occurred using the property name as a key. Further, work history data can also be retrieved using the model information of the air conditioner to be maintained as a key. If the worker does not know the cause of the failure of the air conditioner to be maintained and the corrective measures only with the model information and the abnormality code, the information related to maintenance by searching the work history file 15 by operating the information terminal 80 You can get work history as

  As a method of 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 a worker operates and registers the information terminal 80 or the information processing device 50 can be considered.

  An example of an automatic upload method will be described. The operation history control unit 35 stores the operation data and the operation data in the storage unit 36 at fixed time intervals. When an abnormality occurs in the air conditioner connected to the air conditioning management device 30, the operation history control unit 35 reads out operation data and operation data of a predetermined time before and after the abnormality occurs, and makes model information into these data. Create included work history data. In addition, the operation history control unit 35 attaches, to the operation history data, information on which building and which floor the target air conditioner is installed. Then, the operation history control unit 35 transmits the created operation history data to the data holding device 10b. The control unit 21 of the data holding device 10 b classifies the work history data received from the air conditioning management device 30 for each building and each floor and stores the data in the work history file 15. In this manner, 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 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. Further, the worker may edit the work history data already stored in the work history file 15 by operating the information terminal 80 or the information processing device 50. For example, the worker may operate the information terminal 80 to register work information in the field of the optional information.

  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 in which the same model as the maintenance target is installed. Further, the search processing unit 18 can acquire, for example, work history data associated with the model information from the work history file 15 based on the model information.

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

  When the worker operates the information terminal 80 to input the model information of the air conditioner to be maintained, the information terminal 80 transmits a search request instruction including the model information to the data holding apparatus 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, the search processing unit 18 passes work history data to the display application unit 17 when there is work history data matching the search condition. The display application unit 17 causes the display unit 82 of the information terminal 80 to display the received work history data (step S403). The information terminal 80 displays the work history data on the display unit 82 (step S404).

  In this manner, the worker operates the information terminal 80, and using the work history file 15 held by the database 20 of the data holding device 10b, the air conditioner of the same type as the air conditioner to be maintained has failed in the past. You can refer to the history when it occurred. As a result, the worker can grasp the phenomenon which will occur in the air conditioner to be maintained in the future and cope with it in advance. In addition, 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 worker may operate the information processing apparatus 50 to obtain maintenance information by using the work history file 15 held by the database 20 of the data holding apparatus 10 b via the air conditioning management apparatus 30.

  In recent years, entry into buildings such as buildings is often strictly managed, and air conditioners installed in such buildings are also placed in an environment where communication connection is strictly managed. In maintenance of an air conditioner installed in such an environment, it may be difficult for the operator to connect an information processing device or information terminal for maintenance to the air conditioner management device via a network. Therefore, it is difficult for the worker to collect maintenance information by collating the information at the time of maintenance with the state of the air conditioning management device.

  On the other hand, 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 in units of floors every time the work history data is received from the air conditioning management device 30. Then, the job history file 15 held by the database 20 is stored. Since the data holding device 10 b does not restrict access to the air conditioning management device 30, the air conditioning management device 30 is a data holding device that creates the work history data created each time an abnormality occurs in the air conditioner managed by the own device. 10b can be registered sequentially. Therefore, the data holding apparatus 10b can easily accumulate the latest work history information and can automatically update the maintenance information.

  In the third embodiment, the control unit 21 stores work history data including building history and operation history information when there is an abnormality in the machine type information in building units and floor units. By using the file 15 as the maintenance information, the operator can refer to the history when an abnormality has occurred in the past in the air conditioner of the same model as the air conditioner to be maintained. As a result, the worker can grasp the phenomenon which will occur in the air conditioner to be maintained in the future and 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 is described. However, in the data holding device 10 described in the first embodiment, the work history file 15 is described. It may be provided.

  Also, in order to cause the information processing apparatus including the computer and the server to execute the processing executed by the data holding apparatus described in the first to third embodiments described above, a recording medium in which the procedure of the processing is described in a program May be stored in Further, the information processing apparatus storing the program may provide the program to another information processing apparatus via the network.
