<Configuration and operation of remote management system>
FIG. 3 is a block diagram showing a part of the configuration of the remote management system. As shown in FIG. 1, the remote management system 1 performs remote management of a plurality of properties B1, B2, B3,... A configuration constructed between the remote management device 4 and the property B1 will be described. Further, in the configuration constructed between the remote management device 4 and the property B1, the system of the outdoor unit 7a and the indoor units 8aa, 8ab ..., the system of the outdoor unit 7b and the indoor units 8ba, 8bb ..., and the outdoor unit 7c and the room Since the management of the systems of the units 8ca, 8cb,... Is similar, the remote management system 1 is composed of the indoor units 8aa, 8ab,..., The outdoor unit 7a, the local controller 3a, the remote management device 4, and the service terminal 6. The structure of the part which is present will be described. In addition, since the use of the present invention is to cope with an abnormality of the air conditioner, the configuration and operation necessary for the abnormality are mainly described, and the description of the normal operation and the like is omitted.

  FIG. 3 is a block diagram of abnormality detection in the control of the components of the outdoor unit 7a and the indoor units 8aa, 8ab... Using various sensors by the outdoor side control unit 18 and the indoor side control units 19a, 19b. Will be described. As shown in FIG. 3, the outdoor side control unit 18 of the outdoor unit 7a has a storage unit 30, and the indoor side control units 19a, 19b ... of the indoor units 8aa, 8ab ... have storage units 31a, 31b ... Yes. The storage unit 30 stores an abnormal code notification application 32, and the storage units 31a, 31b,... Store abnormal code notification applications 33a, 33b, and individual number notification applications 34a, 34b,. The abnormal code notification applications 32, 33a, 33b... Are temperature sensors 21 to 24, 27a to 29a, 27b to 29b, pressure sensors 25 and 26, and control objects of the outdoor side control unit 18 and the indoor side control units 19a, 19b. An abnormality is identified based on information sent from each component device and information given to each component device to be controlled, and an abnormality code corresponding to the identified abnormality is identified. The identification of the abnormality is performed based on whether or not the combination of transmission / reception information between the sensor and the control target component device matches the combination of transmission / reception information corresponding to the abnormality code stored in advance. The individual number notification applications 34a, 34b,... Are started when the abnormal code is notified, and the individual numbers of the indoor units 8aa, 8ab,. It has a function.

  3 and the temperature sensors 20 to 24, 27a, 27b, 28a, 28b, 29a, 29b, and the pressure sensors 25, 26 and the control shown in FIG. Since the connection with each target component device is the same as the connection relationship shown in FIG. 2, the description thereof is omitted.

  The outdoor side control unit 18 and the indoor side control units 19a, 19b ... are temperature sensors 20-24, 27a, 27b ..., 28a, 28b ..., 29a, 29b ..., pressure sensors 25, 26, the compressor 11, and four-way switching. When a signal indicating abnormality is received from the valve 12, the outdoor fan 16, the expansion valves 14a, 14b, etc., the indoor fans 17a, 17b, etc., the abnormality indicated by the received signal is specified. If the abnormality occurs in the indoor units 8aa, 8ab,..., The indoor units 8aa, 8ab... Correspond to the individual numbers of the indoor units 8aa, 8ab. The abnormal code is transmitted to the local controller 3a.

  For example, if there is an abnormality such that the indoor fan 17a does not rotate even if it instructs air blowing, the indoor controller 19a recognizes the on / off abnormality of the indoor fan 17a by the abnormality code notification application 33a. An abnormal code corresponding to the on / off abnormality, for example, a code such as “XXX001” is transmitted to the outdoor control unit 18. At that time, the indoor control unit 19a transmits an individual number indicating the indoor unit 8aa, for example, a number such as “YY1001” to the outdoor control unit 18 by the individual number notification application. Receiving the abnormal code and the individual number of the indoor unit 8aa, the outdoor control unit 18 transfers the abnormal code and the individual number to the local controller 3a.

  For example, if the outdoor fan 16 is experiencing an abnormality, the outdoor control unit 18 recognizes the on / off abnormality of the outdoor fan 16 by the abnormality code notification application 32, and turns this on An abnormal code corresponding to the off abnormality, for example, a code such as “XXX101” is transmitted to the local controller 3a. In the case of an abnormality in the outdoor unit 7a, there is usually only one outdoor unit in one system. Therefore, the abnormal code “XXX101” specifies that the abnormal part is the outdoor fan 16 of the outdoor unit 7a. it can. In the case of the outdoor unit 7a, since it is not necessary to identify the individual if the system can be identified as in the conventional case, it is necessary to store the individual number notification applications 34a, 34b ... of the indoor units 8aa, 8ab ... in the storage unit 30. There is no. However, the individual number notification application may be prepared for the indoor units 8aa, 8ab... And the individual numbers of the indoor units 8aa, 8ab.

  As illustrated in FIG. 3, the local controller 3 a includes a communication unit 35, a controller-side control unit 36, and a storage unit 37. The communication unit 35 of the local controller 3a transmits / receives data to / from the outdoor control unit 18 via the communication network 10a, and transmits / receives data to / from the remote management device 4 via the communication line 5 such as the Internet. When an abnormality occurs in the air conditioner 2a, the communication unit 35 receives state data, an abnormality code, and the like sent from the outdoor control unit 18. As the state data, for example, the operation time and the number of operations of the outdoor unit 7a and the indoor units 8aa, 8ab... Of the air conditioner 2a, the rotation speed of the motor of the compressor 11, the on / off of the outdoor fan 16 and the rotation speed, ON / OFF of the indoor fans 17a, 17b..., The number of revolutions, the indoor temperature, the outdoor temperature, the temperature of the outdoor heat exchanger 13, the temperature of the indoor heat exchangers 15a, 15b, and the refrigerant discharged from the compressor 11 And the temperature and pressure of the refrigerant sucked into the compressor 11.

  The controller-side control unit 36 monitors the operating state of the air conditioner 2a in accordance with instructions from the remote management device 4. For monitoring, the controller-side control unit 36 processes the status data and the abnormality code received from the air conditioner 2a. Further, the controller-side control unit 36 may perform control such as on / off control of the outdoor unit 7a and indoor units 8aa, 8ab.

  The storage unit 37 of the local controller 3a stores the state information 38 of the outdoor unit 7a and the indoor units 8aa, 8ab, etc., such as the state data and the abnormality code of the air conditioner 2a received by the communication unit 35, and is necessary for these processes. This information is stored in advance and is output to the controller-side control unit 36. Moreover, the controller side control part 36 memorize | stores the content etc. of the control which performed with respect to the air conditioning apparatus 2a.

  The storage unit 37 stores group / abnormal code correspondence information 39. A group is a group to which members extracted from the same outdoor unit 7a and indoor units 8aa, 8ab... Belong, and the same group is considered together with the abnormal indoor unit when an abnormality is detected. Includes indoor and outdoor units that must be present. In addition, since the affected range and the range to be considered differ depending on the type of abnormality that has occurred, naturally, the allocation of indoor units and outdoor units belonging to a group is performed in accordance with the abnormality code. For this reason, the correspondence between the abnormality code of the indoor unit in which such an abnormality has occurred and the group is described in the correspondence information 39 of the group / abnormal code. In the local controller 3a, not only the indoor unit in which an abnormality has occurred but also the indoor units related thereto are identified as one group from the individual number and the abnormality code. When the property B1 is a building, the indoor units 8aa, 8ab,... Belonging to the same unit belonging to the outdoor unit 7a may belong to different tenants, and the indoor units belonging to the group may be allocated.

  For example, when the indoor fan 17a as described above does not operate, the influence of this abnormality is limited to the indoor unit 8aa. Therefore, the abnormality code indicating the on / off abnormality of the indoor fan 17a. As the group “XXX001”, only the indoor unit 8aa in which the indoor fan 17a is broken may belong. On the other hand, if the expansion valve 14a does not close even if the same indoor unit 8aa is abnormal, the refrigerant flowing to the other indoor units 8ab ... may be insufficient, and an appropriate refrigeration cycle may be performed in the other indoor units 8ab ... It can be difficult. In such a case, not only the indoor unit 8aa but also other indoor units 8ab... Are grouped.

  When an abnormality is detected in the air conditioner 2 a and the local controller 3 a issues an abnormality to the remote management device 4, the local controller 3 a stores the outdoor unit / indoor unit stored in the storage unit 37. Among the status information 38, the status information for 30 minutes before the occurrence of the abnormality is transmitted. However, when the group corresponding to the abnormal code includes only some of the indoor units in the system, the status information is transmitted by focusing on information related to the group. To what extent the status information is transmitted corresponding to the abnormal code is described in the group / abnormal code correspondence information 39.

  Therefore, when there is an abnormality in any of the indoor units 8aa, 8ab... And the local controller 3a sends an abnormality report to the remote management device 4, the individual number, abnormality code, and abnormality code of the abnormal indoor unit are displayed. The corresponding group code and status information related to the group are included in the abnormality notification.

  3 shows only the local controller 3a. However, the fact that the local controllers 3b, 3c,... Shown in FIG. 7a, 7b, 7c... And indoor units 8aa, 8ab..., 8ba, 8bb..., 8ca, 8cb. Therefore, in FIG. 3, the description of the local controllers 3b, 3c... Is omitted, and the redundant explanation is omitted.

  When the remote management device 4 receives the abnormal report from the local controller 3a, the remote management server 4a processes the abnormal report and sends it to the service terminal 6 used by the service person via the communication line 5 such as the Internet. Send information. For example, even if the service number is known to the service person, the service person is not useful for efficient repair. Individuals such as what type of indoor unit is identified by the individual number, where it is installed, and which tenant is using in order for a service person to respond quickly to an abnormality in the property Information related to the number is required. In order to send such information, the remote management device 4 uses the individual number related information 41 in which the information related to the indoor unit specified by the individual number is accumulated in the storage unit 40 of the remote management server 4a, and the abnormal code. An abnormality code related information 42 in which information related to the specified abnormality is accumulated and group related information 43 in which information related to the group is accumulated are stored.

  Here, a specific group setting method will be described. First, on the side of the local controller 3a, during the trial run, the outdoor unit / indoor unit is detected for each system in the same manner as before, and each system is set as a default group. All error codes are set to the default group. Next, an arbitrary group is created with one or more indoor units as components on the local controller 3a side as necessary. At this time, the abnormal code is moved from the default group to the newly created group. When the test run notification transmission process is executed, the created group information is also transmitted to the remote management device 4. In the remote management device 4, a test run report reception process is executed, and the created group information is read.

  When setting a group, one indoor unit is allowed to belong to a plurality of groups. When the failure is caused by a different failure, the influence of the indoor unit in which the failure has occurred is different, and the object to be considered may be different. For example, a failure in which a group G1 in the case of a failure such as the expansion valve of the indoor unit on the first floor is not closed is assigned to the indoor unit arranged on the first floor, and the indoor fan of the same first floor indoor unit does not operate When the group G2 in this case is assigned to the indoor unit that has caused an abnormality arranged on the first floor, the same indoor unit on the first floor belongs to the group G1 and also belongs to the group G2.

  Further, the remote management server 4a of the remote management device 4 has a storage unit 40. In this storage unit 40, rewriting the correspondence information of the group / abnormal code, which is an application for rewriting the correspondence between the abnormal code and the group. An application 44 is stored. By starting the correspondence information rewriting application 44, the group / abnormal code correspondence information 39 stored in the storage unit 37 of the local controller 3a can be rewritten. If it is necessary to set a group of indoor units 8aa, 8ab... During the test operation, the work during the test operation increases and the burden of the operation of operating the air conditioner 2a increases. Therefore, from the remote management device 4, the group / abnormality code correspondence information rewriting application 44 can create an arbitrary new group and change / delete an existing group as needed with one or more indoor units. Like that. When a new group is created from the default group including all outdoor units 7a and indoor units 8aa, 8ab... By the correspondence relationship information rewriting application 44, an appropriate abnormality code is set for the newly created group. For example, after considering the operating condition of the air conditioner 2a, the model, the tenant, and the like, the combination of the group and the abnormal code considered to be appropriate is selected. When a group is created / changed / deleted, the setting information is notified to the local controller 3a. In response to the notification from the remote management device 4, the local controller 3a updates the group information (including the error code information).

  The service terminal 6 includes a communication unit 45, a terminal side control unit 46, a storage unit 47, and a display unit 48. The communication unit 45 of the service terminal 6 transmits and receives data to and from the remote management device 4 via the communication line 5 such as the Internet. When the abnormality occurs in the air conditioner 2a, the communication unit 45 sends information from the remote management device 4 to identify the outdoor unit 7a and the indoor units 8aa, 8ab. In addition, it receives information such as an abnormal situation and information for dealing with the abnormality. The terminal-side control unit 46 mainly performs processing for displaying the information received from the remote management device 4 on the display unit 48. The storage unit 47 of the service terminal 6 stores information transmitted from the remote management device 4.

<Responding to abnormal reports>
A response when an abnormal report is received will be described with reference to FIGS. Hereinafter, regarding the response to abnormalities, when it is necessary to consider the entire system for responding to abnormalities, when it is necessary to consider groups for responding to abnormalities, and only individual indoor units are repaired to respond to abnormalities This will be explained separately.

(Correspondence by system)
As a case where the system must deal with, first, a case where a failure occurs in the outdoor unit 7a is considered. For example, if the outdoor fan 16 is not moving during the cooling operation or dirt is attached to the outdoor heat exchanger 13 and the refrigerant is not sufficiently cooled, the entire system is affected. For example, when the outdoor fan 16 is not moving, the outdoor control unit 18 of the outdoor unit 7a detects an abnormality and transmits an abnormality code “XXX101” corresponding to the abnormality to the local controller 3a. In the local controller 3a, the group corresponding to the abnormality code “XXX101” is specified by the group / abnormal code correspondence information 39. In this case, the group G0 including all the systems shown in FIG. 4 is specified. In addition, in the case of this group G0, the fact that the status data of all the outdoor units 7a and indoor units 8aa, 8ab. Since it is described in the relationship information 39, the local controller 3a includes the error code “XXX101”, information indicating the group G0, and status data for 30 minutes before the occurrence of the abnormality in the abnormality notification, and the remote controller 4 It transmits to the management server 4a. The abnormality is analyzed based on the abnormality report, and the remote management device 4 instructs the serviceman to inspect and repair the outdoor fan 16 of the outdoor unit 7a of the property B1 through the service terminal 6. It is. In this case, since the installation location of the outdoor unit 7a is limited, it is easy for the service person to specify the installation location.

(Group response)
Let us consider a case where some of the indoor units 8aa, 8ab,..., 8af, 8ag,. In this case, an abnormality code “XXX002” indicating that the cooling capacity is insufficient and an individual number of the abnormal indoor unit are transmitted to the local controller 3a via the outdoor unit 7a from some of the indoor side control units 19a, 19b. . In the local controller 3a, the group corresponding to the abnormality code “XXX002” is specified by the group / abnormal code correspondence information 39. In this case, there is a high possibility that the cooling capacity is not sufficient due to the abnormality of each indoor unit. Considering this point, the indoor unit shown in FIG. A group G1 including 8aa, 8ab... Is specified. In the case of the abnormality code “XXX002”, when the group G1 is specified, information indicating that the state data of the groups G2, G3... Is not necessary is described in the group / abnormal code correspondence information 39. The status data of G3... Is not transmitted to the remote management device 4. Therefore, the local controller 3a detects the abnormality code “XXX002”, the individual number of the indoor unit that has transmitted this abnormality code, the information indicating the group G1, and the abnormalities of the indoor units 8aa, 8ab... Belonging to the group G1 and the outdoor unit 7a. The status data 30 minutes before the occurrence is transmitted to the remote management device 4. An abnormality analysis is performed based on the abnormality report, and the remote management device 4 instructs the serviceman through the service terminal 6 to inspect and repair the indoor units 8aa, 8ab... Of the group G1 of the property B1. Is issued. For example, as shown in FIG. 5A, a display is provided on the display unit 48 of the service terminal 6 so that the location where the indoor units 8aa, 8ab... Belonging to the group G1 are installed can be seen at a glance. In FIG. 5 (a), the hatched line indicates the indoor unit that has transmitted the abnormal code. By displaying the location of the indoor unit belonging to the group on the layout screen, the service person can quickly reach the cause of the abnormality in the property where the abnormality has occurred. By linking the individual number related information 41 and group related information 43 shown in FIG. 3 and the layout screen information, a layout screen display as shown in FIG. 5A can be performed.

  In the property B1, the service person can check the indoor units 8aa... Indicated by diagonal lines, and find the cause of the failure such as insufficient refrigerant circulation due to clogged piping on the third floor. At that time, by displaying in a group, the attention of the service person other than the indoor unit that is transmitting the abnormal code is applied, so it is conceivable that the cause of the abnormality can be discovered earlier.

(Individual unit correspondence)
Consider a case where an on / off abnormality has occurred in the indoor fan 17a of the indoor unit 8aa shown in FIG. In this case, the indoor control unit 19a of the indoor unit 8aa transmits the abnormal code “XXX001” indicating the on / off abnormality and the individual number of the abnormal indoor unit 8aa to the local controller 3a via the outdoor unit 7a. . In the local controller 3a, the group corresponding to the abnormality code “XXX001” is specified by the group / abnormal code correspondence information 39. In this case, since it is known that only the indoor unit 8aa needs to be repaired, only the indoor unit 8aa shown in FIG. A group G4 is identified. In the case of the error code “XXX001”, when the group G4 is specified, information indicating that the status data of the component device is not necessary is described in the group / abnormal code correspondence information 39, so the status data is stored in the remote management device. 4 is not sent. Accordingly, the local controller 3a transmits the abnormality code “XXX001”, the individual number of the indoor unit that has transmitted the abnormality code, and information indicating the group G4 to the remote management device 4. The remote management device 4 instructs the serviceman to inspect and repair the indoor unit 8aa of the property B1 through the service terminal 6 without analyzing the abnormality based on the abnormality report. For example, by linking the individual number related information 41 shown in FIG. 3 and the layout screen information, as shown in FIG. 5B, the location of the indoor unit 8aa on the display unit 48 of the service terminal 6 is displayed. It is displayed so that it can be seen at a glance whether it is installed in.

<Grouping>
The abnormality countermeasures in the remote management system 1 and the role of the group in the abnormality countermeasures have been described above. About the group used for such an abnormality countermeasure, a certain degree of effect can be expected by any grouping. However, depending on how the grouping is performed, it may be considered that a difference occurs in the performance of the remote management system 1 for handling an abnormality. Therefore, grouping will be described in more detail with specific methods and examples.

  The effects of grouping are as follows. By grouping, it becomes possible to analyze the device in which an abnormality has occurred in a group unit, and it is considered that the cause of the abnormality can be easily determined as compared with the case where only individual devices are analyzed. Further, if the data that is grouped and transmitted in the event of an abnormality is limited to that of the group, it is considered that there is an effect that the operation data of the equipment necessary and sufficient for analyzing the abnormality that has occurred can be transmitted to the remote management device 4. It is done. Thereby, the communication cost is optimized.

  The conclusion derived from the above is that when grouping is performed, it is preferable to extract components that can maximize the above-described effects.

(Grouping method)
As a grouping method, for example, the following four grouping methods are conceivable. The first method is grouping by the content of the abnormality, the cause of the abnormality, or the abnormality code. In this case, the contents of the same abnormality, the cause of the same abnormality, or the same abnormality code are grouped into one group. In such a case, it is often the case that one unit has an abnormality, but according to the first method, one unit having an abnormality forms one group. By creating one group per unit, the remote management device 4 and the service terminal 6 can recognize that there is little possibility of anomalies in other indoor units, etc., and speed up work. To help.

  Further, not only the same abnormality content and the same cause of abnormality, but also a similar abnormality content, similar cause of abnormality and a plurality of abnormality codes can be used to form a group. In the case of creating a group of similar things, it is determined in advance from experiments and past cases how to combine and create a group. Then, the group is associated with the abnormality in advance so that if the abnormality occurs, the related group data can be sent. For example, the group such as the indoor units 8aa, 8ab... Of the air conditioner 2a of FIG. Is described in the group / abnormal code correspondence information 39 in the storage unit 37 of the local controller 3a.

  The second method of grouping is grouping by usage. In the second method, a plurality of indoor units are classified into those used in the same manner. Then, one group is assigned to the same classification. By grouping in this way, it becomes easy to identify the cause of the abnormality by comparing the normality / abnormality of the components of the same group. For example, those installed in the same indoor space, installed in a server room, installed in a toilet on each floor of an office building, installed in the same space (room), or belonging to the same system Alternatively, it may be grouped based on the same usage such as for perimeter processing / external adjustment processing.

  The third method of grouping is grouping according to the time of use. Groups with the same usage time, day of the week, and usage date (schedule) are grouped together. Further, in the third method, as in the first method, not only the cases where the use periods are completely matched but also those having similar use periods may be classified into the same group. . For example, when indoor units used at midnight in an office building are grouped.

  A fourth grouping method is grouping related to service contents. For example, what is called an energy-saving control service is applied as one group. Here, the energy saving control service is a control for implementing air conditioning by selecting from among a plurality of control methods prepared in advance to reduce energy consumption as much as possible in order to obtain a set environment. . In the case of energy-saving control service, for example, when the difference between the set temperature and the room temperature exceeds a predetermined value, switch to control that quickly eliminates the difference from the set temperature with more emphasis on comfort than omitting energy. Generally, this is set. For example, when such switching frequently occurs, it may be recognized as an abnormality and reported to the remote management device together with operation data. At that time, the indoor units determined to be abnormal for the energy saving control service are grouped, and all the operation data related to the group are reported. Grouping for creating a group used in this case corresponds to the fourth method. A feature of the group according to the fourth method is that grouping is performed mainly on indoor units that the local controller 3a or the like (monitoring device) determines to be abnormal. For the group grouped by the fourth method, the remote management system 1 according to the first embodiment does not have a function of recognizing an abnormality in the local controllers 3a, 3b, 3c... Cannot report to the remote management device 4. A remote management system capable of reporting groups according to the fourth method will be described in the second embodiment.

(Specific examples of grouping)
(1) In the case of a showcase (i) In the case of an equipment contact abnormality in a showcase, the abnormality is limited to the showcase that has occurred. In this case, a group that has been grouped by the first method is used. For example, if there is an anomaly code indicating an anomaly in the contact point of a showcase, one group generates the anomaly code. If the showcase in which the abnormality has occurred corresponds to the indoor units 8aa and 8af in FIG. 4, the local controller 3a transmits past operation data of only these showcases to the remote management device 4. . In the remote management device 4, the two showcases are grouped, making it easier to notice the history common to both cases, for example, when maintenance was performed at the same time, and convenient for exploring the causal relationship of failure It is. Further, since it can be recognized that the abnormality is specific to these indoor units and the necessity of examining other indoor units is small, it is possible to quickly identify the cause by intensively examining the target indoor unit in detail.

  (Ii) In the case of a slow showcase temperature abnormality, an abnormality related to the outdoor unit and other showcases, such as gas leaks. The slow showcase temperature abnormality is, for example, an abnormality in which the minimum temperature of the showcase every 30 minutes rises twice in 6 hours. In this case, a group that has been grouped by the second method is used. The group corresponding to the abnormal showcase temperature includes outdoor units belonging to the same system and other showcases. If the showcase in which the abnormality occurs corresponds to the indoor unit 8aa in FIG. 4, the past operation of the outdoor unit 7a and the showcases 8aa, 8ab..., 8af, 8ag. The local controller 3 a transmits the data to the remote management device 4.

  (Iii) A sudden showcase temperature abnormality is considered to be an abnormality in the showcase that has occurred, such as opening of the door of the showcase or failure of equipment. An abrupt showcase temperature abnormality corresponds to a case where the temperature threshold is exceeded for 10 minutes or more. In such a case, the group that has been grouped by the first method is used, and the same processing as in the case (i) of the showcase described above is performed.

(2) In the case of an office air conditioner (i) In the case of an abnormality of the indoor unit itself, such as an abnormal temperature sensor of the indoor unit, the group according to the first method is used. In this case, the same processing as in the case (i) of the showcase described above is performed, and operation data for only the corresponding indoor unit is transmitted from the local controller to the remote management device.

  (Ii) When the difference between the set temperature of the remote controller of the indoor unit and the suction temperature (room temperature) continues for a long time (for example, 3 hours or more), the group by the second method is used. In this case, all indoor units in the same space can be grouped. The comfort can be evaluated by analyzing past operation data of the indoor units of such a group. For example, if the difference between the set temperature and the suction temperature continues only for a long time, it can be determined that the comfort of the space in which the indoor unit exists is not impaired. Conversely, if most of the indoor units in the same space show the same tendency, it can be determined that the comfort level is reduced. If the number of indoor units that show the same tendency is increasing every time, it can be determined that the comfort is decreasing each time.

  Furthermore, when searching for the reason why the difference between the set temperature and the suction temperature continues for a long time, an outdoor unit and an indoor unit of the same system can be included in the group. By including the outdoor unit and the indoor unit of the same system in the subgroup, this subgroup is analyzed when the cause of the abnormality is extracted. By analyzing the devices of the same system, for example, it becomes easy to identify the cause such as the set temperature and the suction temperature deviating due to insufficient refrigerant circulation.

  (Iii) A nighttime air conditioning stop schedule is set by the energy saving control service, and control for reducing nighttime air conditioning power may be performed. And an anomaly may occur in an indoor unit during such a nighttime air conditioning stop schedule. In such a case, for example, if the temperature sensor abnormality of the indoor unit occurs, if the energy saving control service is not performed, the past operation data of the group grouped by the first method is, for example, FIG. Is received from the indoor unit 8aa and transmitted from the local controller 3a to the remote management device 4.

  However, the occurrence of a temperature sensor abnormality during the nighttime air conditioning stop schedule in the energy-saving control service contradicts the control for stopping the indoor unit. Therefore, in preparation for such a case, grouping by the second method is also performed. That is, all indoor units in the same space are grouped. And the indoor unit which is the object of the nighttime air-conditioning stop schedule is memorize | stored in the memory | storage part 37 of the local controller 3a of FIG. The group / abnormality code correspondence information 39 of the local controller 3a includes a predetermined abnormality (for example, temperature) for a group including all indoor units in the same space and an indoor unit subject to a nighttime air conditioning stop schedule. (Sensor abnormality) is described in association with each other. Furthermore, when a predetermined abnormality occurs in an indoor unit that is subject to a nighttime air conditioning stop schedule, the target of the nighttime air conditioning stop schedule is more than the normal group of the predetermined abnormality grouped by the first method. It is set to give priority to the group associated with the abnormal indoor unit. As a result, when a predetermined abnormality occurs in the indoor unit that is the target of the nighttime air conditioning stop schedule, the past operation data for the group created by the second method, not the group created by the first method Are transmitted from the local controller 3a of FIG. The remote management device 4 can use the data related to this group to check the status of the reason why an abnormality has occurred in the indoor unit that should have stopped in the nighttime air conditioning stop schedule.

  (Iv) If an abnormality occurs periodically, grouping is performed by the third method. In this case, the indoor units with the same schedule are grouped into the same group. However, if an abnormality occurs regularly, it must be determined whether or not the abnormality that has occurred is periodic. For this purpose, for example, the abnormality code notification application 33a of the indoor side control unit 19a in FIG. 3 or the application stored in the storage unit 37 of the local controller 3a determines whether or not the generated abnormality is periodic. For example, compare the period from the date and time when the same abnormality occurred in the same indoor unit last time to the period from the date and time when the same abnormality occurred in the same indoor unit last time to the previous date and time. A predetermined range, for example, within 10% of the period, it is determined as regular. If it is determined that the abnormality occurs periodically, the past operation data of the group of indoor units having the same schedule is transmitted from the local controller 3a in FIG. 3 to the remote management device 4, for example.

  (V) Cancellation commands frequently occur for the energy saving control service, and the state where the energy saving control service cannot be provided may continue. When such cancellation commands for the energy saving control service occur frequently, grouping by the fourth method is performed. In the grouping by the fourth method, the indoor units that the local controller 3a and the like have determined to be abnormal are grouped. Further, as a subgroup, grouping by the second method of grouping all indoor units in the same space as an indoor unit determined to be abnormal can be performed together.

  By using such a group, the remote management device 4 can analyze the indoor unit that is the target of the energy saving control service. Furthermore, it is possible to analyze all the indoor units in the same space as the indoor units for which release commands are frequently issued. Furthermore, by analyzing all the indoor units in the same space to which the specified indoor unit belongs, it is possible to verify the cause of the expected cancellation of the energy saving control service.

  However, it cannot be detected by the outdoor side control unit 18 or the indoor side control units 19a, 19b,... Therefore, the local controller 3a needs an application for recognizing that the cancel command for the energy saving control service has been issued as an abnormality. For this reason, the remote management system 1 according to the first embodiment cannot cope with such a group, and therefore a remote management system having a configuration as shown in the second embodiment is required.

-Second Embodiment-
A remote management system according to the second embodiment of the present invention will be described with reference to FIGS. Similarly to the remote management system 1 of the first embodiment shown in FIG. 3, the remote management system 1A of the second embodiment shown in FIG. 6 also includes the outdoor side control unit 18 and the indoor side control units 19a, 19b,. And a local controller 3aA and a remote management device 4.

  The remote management system 1A of the second embodiment is different from the remote management system 1 of the first embodiment in the configuration of the local controller 3aA. In the remote management system 1A of the second embodiment, except for the configuration of the local controller 3aA, that is, the relationship between the management target and the remote management system 1A is almost the same as that of the first embodiment, and the configuration of the air conditioner 2a is also the first. This is the same as in the first embodiment. Therefore, in the following description, the explanation will focus on the local controller 3aA of the remote management system 1A of the second embodiment.

  The local controller 3aA according to the second embodiment differs from the local controller 3aA according to the first embodiment in that the storage unit 37A notifies the abnormal code that did not exist in the storage unit 37 of the local controller 3a according to the first embodiment. The application 50 and the individual number notification application 51 are provided.

  As described above with respect to grouping, when grouping is performed on service contents (fourth method of grouping), grouping is mainly performed on indoor units that have an abnormality on service contents. Done.

  In this case, an important point is that the indoor side control units 19a, 19b,. If it demonstrates using FIG. 6, the information regarding the service content will be memorize | stored in the memory | storage part 37A of local controller 3aA. For example, among the indoor units 8aa, 8ab..., The indoor unit that is the target of the energy saving control service is stored in the storage unit 37A, and the setting / cancellation of the energy saving control service is performed by the local controller 3aA.

  Here, the relationship between the abnormality related to the service content and the group will be described by taking as an example a case where the matter that the energy saving control service is frequently released is abnormal. First, an example in which an abnormality that the energy saving control service is frequently canceled is defined and the abnormality is detected by the local controller 3aA will be described. Here, the case where an energy-saving control service is cancelled | released 10 times or more per day about the air conditioning apparatus 2a is made abnormal. This condition is described in the abnormal code notification application 50 of the storage unit 37A of the local controller 3aA. Therefore, when it is determined that the energy-saving control service has been canceled 10 times a day with reference to past operation data stored in the indoor unit / outdoor unit state information 38, an abnormal code notification application 50, an abnormality in the energy saving control service is detected. Here, since the latest operation data just acquired is also stored in the storage unit 37 of the local controller 3aA for processing, it is regarded as a form of past operation data.

  When such an abnormality in the energy saving control service is detected, the individual code notification application 50 is activated by the abnormal code notification application 50, and the individual unit notification application 51 receives information on the indoor unit that has been released from the abnormal code notification application 50. Given. Thereby, the individual number notification application 51 is in a state where it can notify the individual number of the indoor unit for which the energy saving control service has been canceled.

  Upon receiving the abnormality detection of the energy saving control service, the local controller 3aA extracts the correspondence between the abnormality and the group. An abnormality code is assigned to the abnormality of the energy saving control service. The local controller 3aA specifies a corresponding group from the group / abnormal code correspondence information 39 using the abnormality code of the energy saving control service and the individual number notified by the individual number notification application 51.

  Then, the local controller 3aA extracts the past operation data of the outdoor unit and the indoor unit belonging to the corresponding group from the indoor unit / outdoor unit state information 38, together with the group identification information, the abnormality code, and the individual number, as shown in FIG. To the remote management device 4 as shown in FIG.

  The group at this time includes an indoor unit that the local controller 3aA has determined to be abnormal, an outdoor unit of the system to which the indoor unit belongs, and an indoor unit. By analyzing the past operation data of all indoor units in the same space as the indoor unit where the anomaly has occurred, it is possible to further examine the cause of frequent cancellation of the energy saving control service on the remote management device 4 side it can.

In the remote management system 1A of the second embodiment, when an abnormality occurs in the indoor unit 8aa or the like as described in the first embodiment, the same operation as the remote management system 1 of the first embodiment can be performed. The remote management system 1A of the second embodiment has all the functions of the remote management system 1 of the first embodiment, but here the remote management system 1A of the second embodiment has to avoid duplication of explanation. Description of the functions of the remote management system 1 of the first embodiment is omitted.
<Modification>
(A)
In the description of the first embodiment, the group / abnormal code correspondence information 39 is stored in the storage unit 37 of the local controller 3a. However, the group / abnormal code correspondence information 39 may be stored in a storage unit other than the local controller 3a. For example, the remote management device 4 can be provided, but in this case, it is not possible to reduce the amount of data in the abnormal report according to the group. Moreover, although it can also be given to the outdoor side control part 18 and indoor side control part 19a, 19b ..., the case of failure of these control wiring boards etc. can be considered. Therefore, it is more convenient to place the group / abnormal code correspondence information 39 in the local controller 3a in order to grasp the correspondence relationship between the group and the abnormal code while relating to all failures of the outdoor unit 7a and the indoor units 8aa, 8ab. It is.

(B)
In the first embodiment, the case where the individual number notification applications 34a, 34b,... Are provided in the indoor units 8aa, 8ab,... Is described, but the indoor units 8aa, 8ab,. If the address can be specified by the address, etc., the individual number notification application may be stored in the outdoor unit 7a so that the outdoor unit 7a notifies the individual number.

(C)
In the above embodiment, the case where the remote management server 4a stores the individual number related information 41 separately from the group related information 43 as information related to the individual in which the abnormality has occurred has been described. The individual number related information 41 may be omitted by including information about the individual in 43.
<Features of the embodiment>
(1)
In the remote management systems 1 and 1A according to the first and second embodiments of the present invention, the individual number notification applications 34a, 34b,... Are transmitted from the local controllers 3a and 3aA (monitoring devices) via the outdoor control unit 18. Based on the individual number (individual identification information), the remote management device 4 identifies an individual in which an abnormality has occurred from among a large number of indoor units 8aa, 8ab... 8ba, 8bb..., 8ca, 8cb. Can do. As a result, the operator of the remote management device 4 can detect an abnormal indoor unit 8aa, for example, for a service person working in a remote place (the property B1) where the indoor unit 8aa where the abnormality has occurred is installed. Specific instructions can be issued.

(2)
Since the group / abnormal code correspondence information 39 stored in the storage units 37 and 37A (storage device) of the local controllers 3a and 3aA (monitoring device) can transmit the group code corresponding to the abnormal code together with the individual number. The necessary and sufficient identification information can be transmitted to cope with the abnormality of the air conditioner 2a. As a result, the abnormality handling work can be performed accurately and the work can be speeded up.

(3)
Because the local controllers 3a and 3aA (monitoring devices) remove the information related to the indoor units 8aa, 8ab... (Individual) and the group related to the abnormality from the information (abnormal information) included in the abnormality report. The amount of information transmitted from the local controllers 3a and 3aA to the remote management device 4 can be reduced.

(4)
By assigning the same indoor unit 8aa to the plurality of groups G1 and G4 by the local controllers 3a and 3aA, the indoor unit 8aa can belong to the plurality of groups G1 and G4 in an overlapping manner. In this way, by allowing one indoor unit 8aa to belong to a plurality of groups G1 and G4 at the same time, it is possible to flexibly cope with the type of abnormality and the state of occurrence.

(5)
The correspondence relationship between the group and the abnormal code (abnormality identification information) can be rewritten by the group / abnormal code correspondence information rewriting application 44 (rewriting means) of the remote management device 4, so that the conditions are set in detail during the first test run. The remote management device 4 can be rewritten after the trial run as necessary.

(6)
The service terminal 6 (reception device) receives the individual number (individual identification information) sent from the remote management server 4a (transmission means) of the remote management device 4 and receives the abnormal indoor unit 8aa, 8ab... Can be specified. Thereby, a service person or the like can quickly identify an abnormal indoor unit. In particular, following the individual number related information 41 related to the individual number, notifying the status of the indoor unit indicated by the individual number is effective for helping the service person to understand.
