  The hard disk 43 includes an IP address storage area 43a, an equipment code storage area 43b, a notification type storage area 43c, a schedule table storage area 43d, and a notification list storage area 43e.

  As shown in FIG. 4A, the IP address storage area 43a stores the IP address assigned to the building terminal device 20 and the building name where the building terminal device 20 is installed in association with each other. Furthermore, the IP address assigned to each of the company center terminal device 50 and the other company center terminal device 70 and the center identification code for identifying each of the company management center and the other company management center (for example, “0102” for the company management center 30) The management center 60 stores “0201”) in association with each other.

  As shown in FIG. 4B, the facility code storage area 43b stores a code for specifying the type of building equipment and the type of building equipment in association with each other. For example, the building water tank facility stores the building facility code “AA” and the building power receiving facility stores the building facility code “AB” in association with each other.

  As shown in (c) of FIG. 4, the notification type storage area 43c stores a code indicating a state included in the notification information and the state in association with each other. For example, the code “00” indicates the occurrence of an abnormality and the code “01” indicates recovery.

  The schedule table storage area 43d stores a schedule table that defines a management center that handles an abnormality of a building equipment device. In this embodiment, the monitoring operation of the equipment is performed by different management centers depending on the date, day of the week, and time. Therefore, a schedule table storing the center identification code of the management center corresponding to the time zone (including date and day of the week) is prepared in advance for each building equipment device, and at the time when the remote management server 40 receives the notification information. Accordingly, the management center corresponding to the notification information may be determined.

  For example, the schedule table 80 in FIG. 5 defines a management center in charge of monitoring work according to the time zone “October 1, 2014”. More specifically, the management center that monitors the building B from 8: 00 to 17: 59 is the other company management center 60 whose center identification code is “0201”, from 18: 00 to 7: 59 (next day). In the meantime, the company management center 30 whose center identification code is “0102” is set to perform monitoring work.

  Further, the alert list storage area 43e stores alert information transmitted from the building terminal device 20. As shown in FIG. 6, the alert list 90 includes a “building name” 91, an “equipment name” 92, an “occurrence time” 93, a “reception time” 94, an “alert type” 95, and a “corresponding destination code”. 96 and a “delivery history” 97 record, and a tag for writing “reception date” 98 (not shown). Hereinafter, details of the writing process to the alert list 90 will be described later.

  Next, with reference to FIG. 7, the flow of processing of the remote monitoring system according to the present embodiment will be described. FIG. 7 is a sequence diagram illustrating a processing flow of the remote monitoring system according to the embodiment.

  As an example of the building equipment, a building water tank facility installed in B building is taken as an example. Water reduction (corresponding to an abnormal state) occurs in the building water tank facility installed in Building B (step SA1), and the state detection sensor 2 installed in the building water tank facility detects the abnormality and generates a sensor signal ( Step SA2) and output to the building terminal device 20B (step SA3).

  The sensor signal acquisition unit 21a of the building terminal device 20B receives the date / time information acquired from the measurement unit 21d and outputs the sensor signal and date / time information to the notification information generation unit 21b. The notification information generation unit 21b generates notification information with reference to each state code and facility code stored in advance in a storage device (not shown) based on the sensor signal (step SA4). For example, when the date and time when the sensor signal is acquired is 7:55 on October 1, 2014, the alarm information “201401001075500AA” is generated using the code 00 indicating abnormality and the code AA indicating the type of building equipment. . As another example of the report information, for example, when a power failure due to a power failure of a building power receiving facility installed in A building is detected at 8:00 on October 1, 2014, the report information “20140100100000AB” is generated. Is done.

  The building transmission control unit 21c outputs the notification information to the external communication device 29 and transmits it to the remote monitoring server 40 via the network (step SA5).

  When the communication control unit 41a of the remote monitoring server 40 receives the notification information from the building terminal device 20B via the external communication device 49, the communication control unit 41a receives the current time information from the time measuring unit 41d, and receives the reception time (eg, 7 (Information indicating time 56 minutes) is added and output to the notification information reception control unit 41b (step SB1).

  Next, the building name extraction unit 41b1 of the notification information reception control unit 41b extracts the IP address of the building terminal device 20B that is the transmission source added to the header of the notification information. Then, referring to the IP address table ((a) of FIG. 4), a building name that matches the extracted IP address, for example, “B building” is specified and written in the “building name” record 91 of the alert list 90 ( Step SB2).

  The equipment name extraction unit 41b2 extracts the equipment code from the report information, refers to the equipment code table (see FIG. 4B), identifies the equipment name corresponding to the extracted equipment code, Write in the “device name” record 92. For example, the facility name extraction unit 41b2 extracts the facility device code “AA” from the bulletin information “201401001075500AA”, and “water tank facility” which is the facility device name that matches the facility device code “AA” from the facility code storage area 43b. And “water tank equipment” is written in the “equipment name” record 92 of the notification list 90. (Step SB3).

  The occurrence time extraction unit 41 b 3 extracts the abnormality occurrence time of the equipment from the notification information and writes it in the “occurrence time” record 93. For example, the occurrence time extraction unit 41b3 extracts the occurrence date “201401001” and the occurrence time “0755” included in the bulletin information “201401001075500AA”, and sets “7:55” in the “occurrence time” record 93 of the bulletin list 90. Write. Also, “2014001” is written in the occurrence date tab 98 (step SB4).

  The reception time extraction unit 41 b 4 writes the system time added when the communication control unit 41 a receives the notification information, “7:56” in the above example, in the “reception time” record 94. (Step SB5).

  The notification type extraction unit 41b5 extracts a signal type code from the notification information, refers to a signal type code table (see (c) of FIG. 4), specifies a state corresponding to the extracted signal type code, Write in the “report type” record 95 (step SB6). In the above example, the report type extraction unit 41b5 writes “abnormal” which is the report type that matches the report type code “00”.

  The correspondence destination code assigning unit 41b6 refers to the schedule table 80 shown in FIG. 5 and extracts the center identification code of the management center that is defined as the person in charge of monitoring work at the reception time included in the notification information. Then, the center identification code is written in the “corresponding code” record 96 in the notification list 90 of FIG. 6 (step SB7). More specifically, the corresponding code adding unit 41b6 refers to the schedule table 80 shown in FIG. 4 and extracts the center identification code stored in the time zone corresponding to the reception time in the building name extracted in step SB2. This is written in the “corresponding destination code” record 96 as the corresponding destination code. In the above example, in the schedule table, the center code stored in the monitoring section of the time zone including the building name “B building” and the reception time “7:56” acquired in step SB5 is “0102”. This corresponds to the other company management center 60 corresponding code.

  The report history writing unit 41b7 writes a code “00” indicating that the report information has not been transmitted to the “distribution history” 97 (step SB8).

  When the process of step SB8 is completed, the notification information reception control unit 41b enters a standby state for extraction command information.

  On the other hand, after the remote monitoring server 40 is activated, the access detection unit 41c1 monitors the presence / absence of access from the company management center 30 or the other company management center 60 based on the presence / absence of distribution request information (step SC1).

  When the communication control unit 41a receives the distribution request information, the communication control unit 41a outputs it to the access detection unit 41c, and specifies the access source of either the company management center 30 or the other company management center 60 (step SC2). The access source is identified by referring to the IP address assigned to the access source center terminal device added to the distribution request information and the IP address table.

  Next, the access detection unit 41c1 determines whether the access source identified in step SC2 is the other company management center 60 or the own company management center 30 (step SC3). If the other company management center 60 (step SC3 / Yes), the other company management The center recognition code or center name corresponding to the center 60 is output to the report list extraction command unit 41c2.

  The bulletin list extraction command unit 41c2 sets extraction conditions for extracting the bulletin information corresponding to the center recognition code or the center name acquired from the access detection unit 41c1, generates the extraction command information including this, and generates the bulletin It outputs to the information reception control part 41b (step SC4).

  When receiving the extraction command information from the notification list extraction command unit 41c2 (step SB9), the reporting information reception control unit 41b refers to the reporting information list 90, and the corresponding code is the corresponding code of the other company management center 60. A certain “0201” and “00” indicating unsent are extracted from the distribution history 97, and a report list for the other company management center 60 is created (step SB10). In the example of the alert list in FIG. 6, the “building name” record 91 is “A building”, the “equipment name” record 92 is “building power receiving equipment”, and the “occurrence time” record 93 is “8”. 0:00 ”,“ reception time ”record 94 includes“ 8:00 ”,“ report type ”record 95 includes“ abnormal ”, and“ correspondence code ”record 96 includes“ 0201 ”. The report list when there is no abnormality report of the equipment to be monitored is “no abnormality”.

  The notification information reception control unit 41b transmits the notification list for the other company management center 60 created in step SB10 to the notification list transmission control unit 41c (step SB11).

  Upon receiving the notification list for the other company management center 60 (step SC5), the notification list transmission control unit 41c detects that the access detection unit 13a has access in step SC1 and communicates with the other company management center 60 where the access is continuing. The notification list is transmitted via the control unit 41a (step SC6).

  The other company management center 60 continues to access from step SC1 accessing the remote monitoring server 40 until receiving the notification list transmission in step SC6. Therefore, the time for maintaining the access state may be set in advance according to the processing time of the remote monitoring server 40 required for specifying the other company management center 60, creating and transmitting the notification list, and the like.

  The communication control unit 41a notifies the notification information reception control unit 41b that the notification list has been distributed (step SC10). The report history writing unit 41b7 stores “01” indicating that the report has been transmitted when the report information is extracted as a report list. “01” may be written at the extracted timing, or may be written after obtaining a feedback signal indicating that the communication control unit 41a has actually delivered to the center terminal device (step SB12).

  If it is determined in step SC3 that the request is from the company management center 30 (SC3 / No), extraction command information for extracting the report information to be handled by the company management center 30 is transmitted and received (SC7, SB9). ), The generation / transmission of the alert list (SB10, SB11, SC8, SC9) is executed. In the example of FIG. 6, the report list for the company management center 30 is “building name” record 91, “building B”, “equipment name” record 92 is “building water tank facility”, and “occurrence time” record 93. Is “7:55”, “reception time” record 94 is “7:56”, “report type” record 95 is “abnormal”, and “correspondence code” record 96 is “0102”. The

  Upon receiving the transmission of the notification list from the remote monitoring server 6, the notification list is displayed at the other company management center 60 or the company management center 30, and monitoring work such as an abnormality recovery work instruction for the equipment by the monitor is executed.

  According to the first embodiment, when the remote management server receives the distribution request information from the company or another company's center terminal device, the company or the center terminal device that transmitted the distribution request information should cope with the communication connection state being maintained. A report list composed of report information is generated. Then, since the alert list is transmitted from the remote management server to the center terminal device, it is not repeatedly transmitted to the center terminal device in a communication interruption state. As a result, it is possible to reduce the load associated with the communication processing of the alert list to the remote management server. In addition, the remote monitoring server does not need to call the company or another company's management center, and can send the alarm information to the company or another company's management center while maintaining the communication connection state, so that the information can be quickly and reliably issued. Can be provided.

  Further, by using the Internet and a telephone line together as a network for connecting the building terminal device and the remote monitoring server, it is possible to provide a transition period from a connection form using a conventional telephone line to a connection form using the Internet. Thereby, it becomes easy to secure the preparation period and cost for updating the building terminal device. In particular, it can be expected to reduce the burden at the time of equipment renewal for a small-scale company or a privately-managed company.

  The above embodiment is merely an example of one embodiment of the present invention and does not limit the present invention. Embodiments within a range not changing the gist of the present invention are included in the present invention. For example, the “abnormal information list” is merely an example of a storage form of abnormal information. If abnormal information can be stored in association with specific information of the management center, the abnormal information is stored in a data structure different from that of the list. May be. In addition, as information for uniquely identifying the management center, information (for example, a MAC address, an IP address, etc.) that uniquely identifies the center terminal device installed in each center may be substituted.

  Also, in the above, it is configured that the company and other company management center monitor one building equipment device by changing the time zone with reference to the schedule table, but even when one management center performs all day monitoring work, The present invention can be applied.

  In the above description, the management center that should correspond to the notification information is determined by referring to the schedule table. However, the center management information that associates the building equipment or building name with the management center that uses the building management information is displayed. It may be prepared in advance, and when the notification information is received from the building terminal device, the corresponding code may be determined with reference to the center management information. In this case, a schedule table is not necessary.
