The remote management center 20 continues the connection and receives abnormality information from the notification device 30 via the first communication line 50. The remote management center 20 generates re-access setting information (see FIG. 6) based on the importance of the abnormality information. The remote management center 20 continues the connection and transmits re-access setting information (see FIG. 6) to the notification device 30 via the first communication line 50 based on the reception of the abnormality information.

  Therefore, since the reaccess setting information (see FIG. 6) is generated based on the importance of the abnormality information, it is possible to reduce the generation of the reaccess setting information (see FIG. 6) more than necessary. Moreover, since it is possible to reduce the re-access setting information (see FIG. 6) being transmitted to the notification device 30 via the first communication line 50 more than necessary, the traffic on the first communication line 50 is reduced. It is possible.

(4)

The re-access setting information 39 (see FIG. 2) includes timing information (see the timing information column 391 shown in FIG. 6). The re-access setting information 39 (see FIG. 2) further includes content information (see content information 392 shown in FIG. 6). The reporting device 30 communicates with the remote management center 20 via the first communication line 50 based on the timing information (see the timing information field 391 shown in FIG. 6) and the content information (see the content information 392 shown in FIG. 6). The connection is established again, and the data of the air conditioning equipment 12 (12a, 12b,...) Is transmitted to the remote management center 20 via the first communication line 50 at a predetermined timing.

  Therefore, based on the timing information (see the timing information column 391 shown in FIG. 6) and the content information (see the content information 392 shown in FIG. 6), the data of the air conditioning equipment 12 via the first communication line 50 at a predetermined timing. 38 (see FIG. 2) is transmitted to the remote management center 20, so that the air conditioning equipment 12 (12a, 12b,...) Is sent via the first communication line 50, the reporting device 30, and the network 14 as necessary. It is possible to monitor.

(6)
Here, based on the fact that the remote management center 20 shown in FIG. 1 continues the connection and receives the abnormality information, the re-access setting information (see FIG. 6) is sent to the notification device 30 via the first communication line 50. Send. The reporting device 30 continues the connection and receives the reaccess setting information (see FIG. 6) via the first communication line 50. The reporting device 30 stores the reaccess setting information (see FIG. 6) as the reaccess setting information 39 (see FIG. 2). The re-access setting information 39 (see FIG. 2) includes timing information (see the timing information column 391 shown in FIG. 6). Based on the timing information (see the timing information column 391 shown in FIG. 6), the reporting device 30 reestablishes the connection with the remote management center 20 via the first communication line 50, and the first communication line at a predetermined timing. The remote management center 20 is accessed via 50. When the remote management center 20 continues the connection established again and is accessed via the first communication line 50 at a predetermined timing by the notification device 30, the control information 25 (see FIG. 3) is first stored. It transmits to the notification device 30 via the communication line 50.

Therefore, the control information 25 (see FIG. 3) is transmitted to the notification device 30 via the first communication line 50 when accessed by the notification device 30 via the first communication line 50 at a predetermined timing. Accordingly, the air conditioning equipment 12 (12a, 12b,...) Can be controlled via the first communication line 50, the notification device 30, and the network 14.
(7)
Here, the reporting device 30 shown in FIG. 1 has the air conditioning equipment 12 (12a, 12b,...) Via the network 14 based on the occurrence of an abnormality in the air conditioning equipment 12 (12a, 12b,...). Receive error information from. The reporting device 30 transmits abnormality information via the first communication line 50 based on the occurrence of an abnormality in the air conditioning equipment 12 (12a, 12b,...). When the reporting device 30 transmits via the first communication line 50, the connection with the remote management center 20 via the first communication line 50 is continued. The remote management center 20 continues the connection and receives abnormality information from the notification device 30 via the first communication line 50. The remote management center 20 continues the connection and transmits re-access setting information (see FIG. 6) to the notification device 30 via the first communication line 50 based on the reception of the abnormality information.
Therefore, since the information transmitted from the reporting device 30 to the remote management center 20 is abnormal information, the remote management center 20 needs to manage the air conditioning equipment 12 (12a, 12b,...) By receiving the abnormal information. The remote management center 20 can determine whether or not there is any.

<Modification of First Embodiment>
(A) The re-access setting information 39 shown in FIG. 2 may not be information as shown in FIG. For example, the timing information column 391 shown in FIG. 6 may store a predetermined time interval and a predetermined number of times that the reporting device 30 should access the remote management center 20. In this case, in step S9 shown in FIG. 5, it is determined whether or not a predetermined time interval has elapsed. In step S13, it is determined whether or not access to the remote management center 20 has been performed a predetermined number of times.

  Further, in the content information column 392 shown in FIG. 6, information (such as an ID number) for identifying data to be transmitted from the reporting device 30 to the remote management center 20 may be stored. The information in the content information column 392 may be “operation data of the outdoor units 12aa,... And the indoor units 12ab,. Alternatively, the information in the content information column 392 may be “operation data of the outdoor unit group (12aa,...) Or the indoor unit group (12ab, 12ac, 12ad,. . Alternatively, the information in the content information column 392 may be “operating data of the air conditioner group 12a (12aa, 12ab, 12ac, 12ad,...)” That is abnormal. The content information stored in the content information column 392 may be different information for each timing. In this case, since different data is transmitted to the remote management center 20 shown in FIG. 1 based on the content information, the air conditioning equipment 12 (12a, 12b,...) Is transmitted via the first communication line 50, the notification device 30, and the network 14.・ ・) Can be closely monitored.

  The abnormality information received by the receiving unit 33 illustrated in FIG. 2 may not be the operation data when the abnormality of the air conditioning equipment 12 (12a, 12b,...) (See FIG. 1) occurs. For example, data indicating only the presence / absence of an abnormality (such as an abnormality code), information (such as an address) for identifying the outdoor unit 12aa,... Or the indoor unit 12ab,. And information related to at least one of operation data when an abnormality occurs in the air conditioning equipment 12 (12a, 12b,...) (See FIG. 1).

  The data 38 of the air conditioning equipment 12 shown in FIG. 2 includes operating data (suction air temperature, suction air humidity, heat exchanger temperature, compressor discharge pressure) of the air conditioning equipment 12 (12a, 12b,...) (See FIG. 1). , Driving time, etc.). For example, data when the air conditioner 12 (12a, 12b,...) (See FIG. 1) is stopped (temperature near the suction port, humidity near the suction port, heat exchanger temperature, stop time, etc.), air conditioner 12 (12a, 12b,...) (See FIG. 1) operation data (suction air temperature, suction air humidity, heat exchanger temperature, compressor discharge pressure, operation time, etc.) and air conditioning equipment 12 (12a, 12b,. ..) Information on at least one of the power consumption amounts (see FIG. 1) may be used.

  In addition, after it is determined that the predetermined timing has been reached in step S9 shown in FIG. 5, before the remote management center 20 is accessed in step S10 shown in FIG. 5, the receiving unit 33 of the notification device 30 shown in FIG. Thus, the operation data of the air conditioning equipment 12 may be received from the air conditioning equipment 12 (12a, 12b,...) (See FIG. 1) via the network 14. The operation data of the air conditioning equipment 12 may be received from the receiving unit 33 by the control unit 35 and stored in the storage unit 36 as the data 38 of the air conditioning equipment 12.

  (B) In step S1 shown in FIG. 4, the timing at which abnormality information is received from the air conditioning equipment 12 (12a, 12b,...) Via the network 14 shown in FIG.・ ・) It does not have to be the same time that the abnormality occurred. That is, information for inquiring about the presence / absence of abnormality of the air conditioning equipment 12 (12a, 12b,...) (See FIG. 1) by the transmission unit 34 of the notification device 30 shown in FIG. , 12b,...) (See FIG. 1). In this case, even if an abnormality occurs in the air conditioning equipment 12 (12a, 12b,...) (See FIG. 1), the reception unit 33 receives the abnormality information at the timing when the transmission unit 34 inquires. .

  The control unit 35 of the notification device 30 illustrated in FIG. 2 does not have to pass the abnormality information to the transmission unit 32 immediately after receiving the abnormality information. That is, as illustrated in FIG. 2, the control unit 35 may receive the abnormality information from the reception unit 33 and store the abnormality information in the storage unit 36 as the abnormality information 37. In this case, the control unit 35 may pass the abnormality information 37 to the transmission unit 32 at a timing when the abnormality information 37 is accumulated to some extent, or may pass the abnormality information 37 to the transmission unit 32 at regular timing.

  The process of step S11 shown in FIG. 5 may be performed only at the first timing. Alternatively, it may be performed only when a need arises. The transmission of the data 38 of the air conditioning equipment 12 to the remote management center 20 in step S10 may be performed only at the first timing. Alternatively, it may be performed only when a need arises. If the data 38 of the air conditioning equipment 12 is not transmitted to the remote management center 20 in step S10, only the access to the remote management center 20 is performed. For example, dummy information may be transmitted, or information requesting a reply may be transmitted.

  (C) The firewall 40 shown in FIG. 1 may be a packet filtering type, an application gateway type, or a stateful inspection type, and is difficult to actively access from outside the building 10 via the first communication line 50. Any thing can be used. The air conditioning equipment 12 (12a, 12b,...), The reporting device 30, and the firewall 40 may be provided in a hospital, school, apartment house, or the like instead of the building 10. The air conditioner group 12a may include a plurality of outdoor units and a plurality of indoor units, or may include one outdoor unit and one indoor unit. Other air conditioner groups 12b,... May be the same as the air conditioner group 12a. The first communication line 50 and the network 14 may adopt the same protocol or different protocols.

  (D) The notification device 30 shown in FIG. 1 may not transmit the abnormality information via the first communication line 50 based on the occurrence of the abnormality of the air conditioning equipment 12 (12a, 12b,...). . For example, when the air conditioners 12aa,... Are newly installed, only the newly installed air conditioners 12aa,. 12a, 12b,...), The equipment information may be transmitted from the reporting device 30 to the remote management center 20 via the first communication line 50. Here, the equipment information is information related to the air conditioning equipment 12 (12a, 12b,...) And is information received from the air conditioning equipment 12 (12a, 12b,...) Via the network 14. Even in this case, the reporting apparatus 30 accesses the remote management center 20 via the first communication line 50 based on the re-access setting information 39 (see FIG. 2) based on the fact that the equipment information is received by the remote management center 20. Therefore, it is possible to connect the notification device 30 and the remote management center 20 in a pseudo real time as necessary. Therefore, it is possible to sufficiently manage the air conditioning equipment 12 (12a, 12b,...) Via the first communication line 50, the reporting device 30, and the network 14 as necessary.

  Here, the equipment information may include at least one of performance information, load information, and usage state information. The performance information is information regarding the performance of the air conditioning equipment 12 (12a, 12b,...). The load information is information related to the load of the air conditioning equipment 12 (12a, 12b,...). The use state information is information related to the use state of the air conditioning equipment 12 (12a, 12b,...). When the air conditioners 12aa,... Are newly installed, the performance information is included in the equipment information when it is desired to manage whether the performance of the air conditioners 12aa,. When it is desired to manage the load of the air conditioners 12aa,..., The load information is included in the equipment information. When it is desired to manage the usage status (usage time zone, usage frequency, etc.) of the air conditioners 12aa,..., The usage status information is included in the equipment information.

  The equipment information may include at least one of abnormality information, performance information, load information, and usage state information. In this case, since the equipment information includes at least one of abnormality information, performance information, load information, and usage status information, when the remote management center 20 receives the equipment information, the air conditioning equipment 12 (12a, 12b,. The remote management center 20 can determine whether or not it is necessary to manage.

  Moreover, when the overload state of the air conditioning equipment 12 (12a, 12b,...) Is expected, the equipment information of the air conditioning equipment 12 (12a, 12b,...) Is notified via the first communication line 50. It may be transmitted from the device 30 to the remote management center 20. Also in this case, the reporting device 30 accesses the remote management center 20 via the first communication line 50 based on the re-access setting information 39 (see FIG. 2) based on the fact that the equipment information is received by the remote management center 20. Therefore, it is possible to connect the notification device 30 and the remote management center 20 in a pseudo real time as necessary. Therefore, it is possible to sufficiently manage the air conditioning equipment 12 (12a, 12b,...) Via the first communication line 50, the reporting device 30, and the network 14 as necessary.

  Here, the facility equipment information may include at least one of load information and usage state information. When an overload condition of the air conditioner 12 (12a, 12b,...) Is expected, load information is included in the equipment information when it is desired to manage the load of the air conditioner 12aa,. Will be. When it is desired to manage the usage status (usage time zone, usage frequency, etc.) of the air conditioners 12aa,..., The usage status information is included in the equipment information.

  The equipment information may include at least one of abnormality information, performance information, load information, and usage state information. In this case, since the equipment information includes at least one of abnormality information, performance information, load information, and usage status information, when the remote management center 20 receives the equipment information, the air conditioning equipment 12 (12a, 12b,. The remote management center 20 can determine whether or not it is necessary to manage.

  (E) The equipment management system 1a shown in FIG. In other words, the facility equipment management system 1a may further include an ISP (Internet Service Provider) 80a and a fourth communication line 90a. The remote management center 20 and the ISP 80a are connected by a first communication line 50a. The first communication line 50a may be a wide area network line. The reporting device 30a and the ISP 80a are connected by a fourth communication line 90a. The fourth communication line 90a may be a local area network line. Here, the IP address of the reporting device 30a can be used only in the fourth communication line 90a, and is not an effective address in the first communication line 50a. That is, the IP address of the reporting device 30a is a local address.

  At this time, the reporting device 30a can access the remote management center 20 by specifying the IP address of the remote management center 20 (an effective address in the first communication line 50a). On the other hand, since the reporting device 30a does not have a valid address in the first communication line 50a, the remote management center 20 is connected to the remote management center 20 after the abnormality of the air conditioning equipment 12 (12a, 12b,...) Occurs. It is difficult to actively acquire the data (12a, 12b,...) And to actively control the air conditioning equipment 12 (12a, 12b,...). Even in this case, the notification device 30 receives the re-access setting information 39 (see FIG. 2) via the first communication line 50 based on the occurrence of an abnormality in the air conditioning equipment 12 (12a, 12b,...). Therefore, it is possible to connect the notification device 30 and the remote management center 20 in a pseudo real time if necessary. For this reason, the abnormality of the air conditioner 12 (12a, 12b,...) Can be sufficiently managed through the first communication line 50, the notification device 30, and the network 14 as necessary.

  (F) The equipment management system 1b shown in FIG. That is, the facility equipment management system 1b may further include an in-house switch 80b and a fourth communication line 90b. The first communication line 50b may be a public telephone line. The fourth communication line 90b may be an extension telephone line. Here, the telephone number (address) of the reporting device 30b can be used only in the fourth communication line 90b, and is not a valid telephone number (address) in the first communication line 50b. That is, the telephone number (address) of the reporting device 30b is an extension number.

  At this time, the reporting device 30b can access the remote management center 20 by specifying the telephone number of the remote management center 20 (a telephone number (address) that is valid on the first communication line 50b, that is, an outside line number). On the other hand, since the reporting device 30b does not have a valid telephone number (address) on the first communication line 50b, the remote management center 20 has a remote management center 20 after an abnormality of the air conditioning equipment 12 (12a, 12b,...). However, it is difficult to actively acquire data of the air conditioning equipment 12 (12a, 12b,...) Or to actively control the air conditioning equipment 12 (12a, 12b,...). Even in this case, the notification device 30b receives the re-access setting information 39 (see FIG. 2) via the first communication line 50b based on the occurrence of an abnormality in the air conditioning equipment 12 (12a, 12b,...). Therefore, if necessary, the notification device 30b and the remote management center 20 can be connected in a pseudo real time. For this reason, the abnormality of the air conditioner 12 (12a, 12b,...) Can be sufficiently managed through the first communication line 50b, the reporting device 30b, and the network 14 as necessary.

  (G) The facility equipment management system 1c shown in FIG. 9 may not include the firewall 40. That is, the facility equipment management system 1c may further include an in-house switch 80c and a fourth communication line 90c. The first communication line 50c may be a public telephone line. The fourth communication line 90c may be an extension telephone line. Here, the telephone number (address) of the reporting device 30c is an external line number common to other devices (for example, a fixed telephone (not shown)). The reporting device 30c may have an extension number separately from the outside line number.

  At this time, since the reporting device 30c has an external line number (address) in common with other devices (for example, a fixed telephone (not shown)) in the first communication line 50c (public telephone line), the remote management center 20 has the reporting device. When transmitting to the telephone number (address) of 30c, there is a possibility that another device (for example, a fixed telephone (not shown)) may receive it. The information transmitted from the remote management center 20 to the telephone number (address) of the notification device 30c may not be received by the notification device 30c.

Or the air conditioner 12 (12a). , 12b,...) Are not actively controlled. Even in this case, the notification device 30c receives the re-access setting information 39 (see FIG. 2) via the first communication line 50c based on the occurrence of an abnormality in the air conditioning equipment 12 (12a, 12b,...). Therefore, it is possible to connect the notification device 30c and the remote management center 20 in a pseudo real time if necessary. For this reason, the abnormality of the air conditioner 12 (12a, 12b,...) Can be sufficiently managed through the first communication line 50c, the reporting device 30c, and the network 14 as necessary.

  The facility equipment management system 1c shown in FIG. 9 may not include the in-house switch 80c and the fourth communication line 90c. Even in this case, since the telephone number (address) of the reporting device 30c is an external line number common to other devices (for example, a fixed telephone (not shown)), the remote management center 20 transmits to the telephone number (address) of the reporting device 30c. It is the same that the information that has been received may not be received by the reporting device 30c.

  (H) The equipment managed by the equipment management system 1 via the first communication line 50 may be equipment other than the air conditioning equipment 12 (12a, 12b,...).

The transmission unit 127 transmits the data 38 (see FIG. 2) of the air conditioning equipment 12 to the contact center 170 via the third communication line 160 based on the request information. In addition, the control unit 123 determines control information based on the request information. The control unit 123 stores the determined control information in the storage unit 124 as control information 125. These points are different from the first embodiment.

Further, the flow of processing in which the equipment management system 100 shown in FIG. 10 manages the abnormality of the air conditioning equipment 12 (12a, 12b,...) Via the first communication line 50 is as shown in FIGS. The following points are different from the first embodiment. In FIG. 12 and FIG. 13, the same processing as that of the first embodiment shown in FIG. 4 and FIG.
In step S101 shown in FIG. 13, request information is accepted. That is, the request information is received from the contact center 170 (see FIG. 10) via the third communication line 160 by the receiving unit 126 of the remote management center 120 shown in FIG. That is, request information is accepted. Here, the request information is information on a request related to managing the air conditioning equipment 12 (12a, 12b,...) (See FIG. 10) via the first communication line 50. If the request information is not transmitted from the contact center 170 (see FIG. 10), the receiving unit 126 receives empty (NULL) information.

  In step S102 shown in FIG. 13, it is determined whether there is request information. That is, when the request information is received from the reception unit 126 by the control unit 123 of the remote management center 120 illustrated in FIG. 11, the request information is determined to be present, and when the request information is not received from the reception unit 126. It is judged that there is no. If it is determined that there is request information, the process proceeds to step S103. If it is determined that there is no request information, the process proceeds to step S11.

  In step S103 shown in FIG. 13, transmission is performed to the contact center. That is, the control unit 123 of the remote management center 120 shown in FIG. 11 passes the data 38 (see FIG. 2) of the air conditioning equipment 12 to the transmission unit 127 based on the request information. Based on the request information, the transmission unit 127 transmits the data of the air conditioning equipment 12 (12a, 12b,...) (See FIG. 10) to the contact center 170 (see FIG. 10) via the third communication line 160. .

In step S104 shown in FIG. 13, control information is determined. That is, the control information is determined based on the request information by the control unit 123 of the remote management center 120 shown in FIG. The control information determined by the control unit 123 is stored in the storage unit 124 as control information 125.
Therefore, the remote management center 120 shown in FIG. 10 receives the request information via the third communication line 160 and transmits the data 38 (see FIG. 2) of the air conditioning equipment 12 via the third communication line 160 based on the request information. Based on the request information, it is possible to monitor the air conditioning equipment 12 (12a, 12b,...) Via the first communication line 50, the notification device 30, and the network 14. In addition, since the remote management center 120 receives the request information via the third communication line 160 and determines the control information based on the request information, the air conditioning equipment 12 via the first communication line 50, the notification device 30, and the network 14. Control of (12a, 12b,...) Can be performed based on the request information.

  Since the notification device 30 shown in FIG. 10 accesses the remote management center 120 via the first communication line 50 based on the re-access setting information 39 (see FIG. 2), the notification device 30 and the remote management center 120 are necessary as necessary. Are similar to those in the first embodiment in that they can be connected in a pseudo-real time manner. Therefore, even with such an equipment management system 100, if necessary, abnormalities in the air conditioning equipment 12 (12a, 12b,...) Are sufficiently obtained via the first communication line 50, the reporting device 30, and the network 14. It is possible to manage.

(See FIG. 10) via the first communication line 50. There may be information on a request for controlling the air conditioning equipment 12 (12a, 12b,...) (See FIG. 10) via the first communication line 50, or the air conditioning equipment 12 (12a). , 12b,...) (See FIG. 10) may be information on a request for monitoring and controlling via the first communication line 50.

  (B) In step S102 shown in FIG. 13, the timing for determining whether or not there is request information may not be the same as the timing at which the request information is received. That is, the request information may be received from the reception unit 126 and stored in the storage unit 124 by the control unit 123 illustrated in FIG. Then, the control unit 123 may determine whether there is request information by referring to the storage unit 124 at a timing when the request information is accumulated to some extent, or may request the storage unit 124 by referring to the storage unit 124 at a regular timing. It may be determined whether there is information.

(C) The first communication line 50 and the third communication line 60 may pass through the same network (for example, the Internet). The first communication line 50, the third communication line 60, and the network 14 may employ the same protocol, or may employ different protocols.
(Third embodiment)
An equipment management system 200 according to a third embodiment of the present invention will be described with reference to FIGS.

In addition, about the whole structure of the installation equipment management system 200 concerning 3rd Embodiment shown in FIG. 14, and the structure of the 212 air conditioning equipment group, it is the same as that of 2nd Embodiment of FIG. Therefore, detailed description thereof is omitted here.
FIG. 15 shows a logical configuration of the notification device 230 according to the third embodiment, and FIG. 16 shows a logical configuration of the remote management center 220.

<Configuration of reporting device 230>
The notification device 230 illustrated in FIG. 15 mainly includes a first reception unit 231, a first transmission unit 232, a second reception unit 233, a second transmission unit 234, a control unit 235, and a storage unit 236.

Each of the second reception unit 233 and the second transmission 234 receives and transmits information with the air conditioning equipment 212 group (212a, 212b,...) (See FIG. 14) via the local network 214.

The control unit 235 processes information from the first and second reception units 231 and 233 and delivers the processed information to the first and second transmission units 232 and 234. In addition, the control unit 235 stores the processed information in the storage unit 236. These configurations are the same as those in the first embodiment.
The storage unit 236 stores a monitoring information DB 237, an air conditioning equipment DB 238, a re-access setting information DB 239, and the like. The air conditioner DB 238 stores information for identifying each air conditioner, such as model name and serial number, date and time when the air conditioner was installed, operation data for a certain period in the past, and the like. Similar to the first embodiment, the re-access setting information DB 239 is information for re-accessing and includes timing information 391 and a content information column 392 (see FIG. 6).

  Here, the monitoring information DB 237 includes information on the newly installed air conditioning equipment 212. Since the air conditioning equipment 212 is newly installed, it is necessary to frequently monitor whether it operates normally for a certain period of time. The newly installed air conditioning equipment 212 data is newly stored in the air conditioning equipment DB 238 via the notification device 230 after installation, and is also stored in the monitoring information DB 237.

<Configuration of Remote Management Center 220>
The remote management center shown in FIG. 16 mainly includes a receiving unit 221, a transmitting unit 222, a control unit 223, and a storage unit 224.
Each of the reception unit 221 and the transmission unit 222 receives and transmits information with the notification device 230 via the first communication line 250. The control unit 223 processes information from the reception unit 221 and delivers the processed information to the transmission unit 222. The control unit 223 stores the processed information in the storage unit 224. These configurations are the same as those in the first embodiment.

The storage unit 224 stores a control information DB 225, an importance list 226, a schedule 227, and the like.
The control information DB 225 stores information for controlling the air conditioning equipment 212 and includes a preset control pattern.
The importance list 226 includes information on air conditioning equipment (for example, model name, date and time of installation of air conditioning equipment, operation data for a certain period in the past, report record, etc.) and customer information (industry, region, past complaint data, etc.) This is a list of importance levels determined based on the content of the report and the pattern of the situation. This importance list is updated, for example, when the remote management center 220 receives information input by the operator of the contact center 270 via the third communication line 260 (see FIG. 14).

The schedule 227 is a schedule for an air conditioning facility that is currently set for re-access due to occurrence of abnormality or monitoring.
<Processing flow of facility equipment management system 200>
The process flow of the equipment management system 200 shown in FIG. 14 will be described along the flowchart of FIG. The flowchart of FIG. 17 includes steps S301 to S315. FIG. 17A shows the flow of the first half and FIG. 17B shows the flow of the second half.

In FIG. 17A, in S301, the reporting device 230 receives information on the newly installed air conditioning equipment 212. At this time, the information of the newly installed air conditioning equipment 212 is stored in the monitoring information DB 237 of the storage unit 236, and the air conditioning equipment DB 238 is also updated.
In S302, the reporting device 230 reports the monitoring information of the air conditioning equipment 212 to the remote monitoring center. Next, in S303, the remote monitoring center 220 receives the monitoring information.

  In S304, the control unit 223 of the remote monitoring center 220 reads the importance list 226. Next, in S305, the control unit 223 collates the monitoring information of the air conditioning equipment 212 with the read importance list, and determines the importance of the air conditioning equipment 212 in the monitoring information. For example, the air-conditioning equipment 212 is determined based on the newly installed air-conditioning equipment 212, the characteristics depending on the model, the customer who uses the air-conditioning equipment 212, the type of business of the customer, particularly the items desired by the customer. Determine the importance for. The re-access setting information of the air conditioning equipment 212 is set so as to preferentially re-access at a short time interval when the importance is high, and is set at a longer time interval when the importance is low.

  In S306, system load prediction is performed. The control unit 223 of the remote monitoring center 220 reads the schedule 227 and adjusts the re-access schedule of the air-conditioning equipment 212 with reference to the re-access schedule of other air-conditioning equipment that has already been set for re-access. For example, avoid times when access is concentrated. In this way, a re-access schedule for the air conditioning equipment 212 is created in S307. The newly created schedule is written in the schedule 227.

In S308, re-access setting information is created based on the created schedule and transmitted to the reporting device 230 in S309.
Note that, as in the first embodiment, the connection between the remote monitoring center 220 and the notification device 230 is continued until the re-access setting information is transmitted from the remote monitoring center 220 to the notification device 230.

In FIG. 17B, in S310, when the reporting device 230 receives the re-access setting information of the air conditioning equipment 212, it is written in the re-access setting information DB 239. As in the first embodiment, after this reception, the connection between the remote monitoring center 220 and the notification device is once terminated.
Thereafter, in S311, the control unit 235 of the notification device 230 reads the re-access setting information DB 239 and determines whether or not a predetermined timing for re-accessing the air conditioning equipment 212 has come. If it is the predetermined timing, the reporting device 230 reaccesses the remote management center in S312.

  In S 313, in response to the re-access, the control information related to the air conditioning equipment 212 is downloaded from the remote management center 220 to the notification device 230. Moreover, since the re-access regarding the air conditioning equipment 212 was performed once, the information of the schedule 227 is updated. In S <b> 314, the reporting device 230 that has received the control information controls the air conditioning equipment 212. Since this control is performed once, the re-access setting information DB regarding the air conditioning equipment 212 is updated.

In S315, it is determined whether or not all the re-access schedules related to the air conditioning equipment 212 have been completed. If not completed, the process returns to the previous step.
Although not shown, the monitoring information DB 237 related to the air conditioner 212 in the notification device 230 is updated or deleted every time re-access is executed or at the end of the re-access schedule, and the air conditioner DB 238 is also updated accordingly.

<Features of Third Embodiment>
According to the equipment management system 200 according to the present embodiment, in addition to the features (1) to (7) of the first embodiment, it has the following features.
(3-1)
In the equipment management system 200 according to the present embodiment, importance is taken into account when creating re-access setting information. This importance is determined based not only on the information on the air conditioning equipment 212 itself but also on business information such as the customer in use, the type of business, and the installation location. By differentiating this information, more detailed maintenance and customer service can be provided.
(3-2)
In the equipment management system 200 according to the present embodiment, in creating the re-access setting information, the schedule is adjusted and created by predicting the system load. The prediction of the system load is performed by referring to the schedule 227. For example, a schedule is created avoiding the time zone when access is concentrated, and re-access setting information is created based on this schedule. Therefore, since the system load is reduced, a more reliable system operation is possible.
<Modification of Third Embodiment>
(A) The information stored in the monitoring information DB 237 is not limited to the newly installed air conditioning equipment. For example, the present invention can be applied to the case where the air conditioning equipment is monitored at an event where the air conditioning load is higher than usual, such as a department store at a bargain sale time. Or it is not restricted to such a special situation, For example, the case where the operation data of an air-conditioning installation etc. are stored as a daily report, and it transmits to the remote management center 220 regularly is also included. It is also possible to store and handle all of this information and the abnormality information in the first embodiment.
(B) The importance list includes items such as the frequency of abnormality reporting. If the importance of air conditioners that are frequently reported is high, the schedule may become dense during re-access settings. On the other hand, if the problem is solved by repair, it is not necessary to re-access frequently. Therefore, in such a case, the system load can be reduced by resetting the reaccess setting or changing the scheduling.

  The equipment management system, management device, equipment management method, and equipment management program according to the present invention sufficiently manage equipment via the first communication line, the reporting device, and the second communication line as necessary. It is useful as an equipment management system, management device, equipment management method, equipment management program, and the like.
