The scheduled notification time 34a is the latest arrival time from the present time, and k scheduled notification times 34a to 34k are stored from the current time to the future.

  Next, a procedure for processing the management device information transmitted from the building management device 4 of the building remote monitoring system by the center device 3 will be described with reference to FIGS. FIG. 4 is a flowchart of a procedure for processing management device information. Moreover, FIG. 5 shows a state of setting the scheduled notification time over five days of the building management apparatus 4 installed in the three buildings 1 as a specific example for explanation. ● represents the scheduled notification time set for A building, ○ for B building, and Δ for C building. Here, scheduled notifications are scheduled every 10 hours. In addition, the current time will be described as 13:00 on the first day. Further, in the following description, a building that requires setting of the scheduled notification time will be described as D building. In D building, the system is reset and monitoring is being resumed. In addition, a building that requests a monitoring stop will be described as a C building.

In step 101 of FIG. 4, the transmission / reception means 12 receives the management device information 21 transmitted from the building management device 4 of a certain building 1, and the management information processing means 13 receives the management device information from the management device information 21. The building management device 4 that has transmitted 21 is identified based on the building management device code 22, and the process proceeds to step 102.
In step 102, the management information processing means 13 determines whether or not the scheduled notification time setting request code 24 is set in the received management device information 21, and when the scheduled notification time setting request code 24 is set, The process proceeds to step 103, and if the scheduled notification time setting request code 24 is not set, the process proceeds to step 106. In the description here, step 103 to step 105 will be described on the assumption that the request for setting the scheduled notification time is from building D.
In step 103, the time setting means 14 refers to the scheduled notification time 34 of each building 1 after the current time from the scheduled notification time management record 31 stored in the storage means 11, and reports the scheduled reports of any two buildings. A time in the middle of the interval having the longest interval between the times is set as a candidate for the scheduled notification time of D building. Here, it demonstrates concretely using FIG. When the interval between the two scheduled notification times is determined from the scheduled notification time set on the first day after 13:00, the time between 16:00 and 20:00 and between 20:00 and 24:00 is 4 hours apart. The intermediate time between 16:00 and 20:00 and 20:00 and 24:00 becomes 18:00 and 22:00. From this time, the most recent time 18:00 from the present time is selected as the scheduled notification time for the D building, and the routine proceeds to step 104.
In step 104, the transmission / reception means 12 transmits the time 18:00 selected as the scheduled notification time to the building management device 4 of D building. In the building management device 4 of D building, the management device information transmission means 15 writes the transmitted scheduled notification time at 18:00 into the storage means 16, and when the time of the built-in clock 20 arrives at 18:00, The management device information is transmitted to the center device 3.
In step 105, the storage means 11 writes the scheduled notification time in the scheduled report time field of the D building scheduled report time management record 31, and ends the processing.
In step 106, the management information processing means 13 determines whether or not the monitoring stop code 26 is set in the management device information. When the monitoring cancellation code 26 is set, the process proceeds to step 107, and when it is not set, the process proceeds to step 108. In the description here, step 106 and step 107 will be described on the assumption that the monitoring stop code 26 is set in the management device information 21 from the building management device 4 of the C building.
In step 107, the storage unit 11 deletes the scheduled notification time of the building management device 4 of the building C that has transmitted the management device information 21 by setting the monitoring cancellation code 26 from the scheduled notification time management record 31, and ends the processing. To do. Next, when there is a request for setting a scheduled notification time from any building, the scheduled report time described in step 103 is selected based on the latest scheduled report time management record 31.
In step 108, the management information processing means 13 determines whether or not the scheduled report code 25 is set in the management device information 21. When the scheduled report code 25 is set, the process proceeds to step 109, and when the scheduled report code 25 is not set, the process proceeds to step 110.
In step 109, the management information processing means 13 performs a scheduled notification reception process and ends the process.
In step 110, the management information processing means 13 performs an abnormality monitoring reception process, and the process ends.
In this way, the scheduled notification time for a new building can be selected in the quietest time zone.

  Such a building remote monitoring system receives the management device information from the building management device, determines the most quiet time zone based on the scheduled notification time management data for managing the scheduled notification time of each monitored building, and Time setting means is provided in the building management device to set the quiet time as the scheduled notification time for the building, so that the scheduled notifications are concentrated in a specific time zone, the telephone line is congested and the load on the center device is concentrated. Can be prevented.

  In addition, it is possible to reduce the labor of setting work on the building management apparatus by maintenance personnel.

  In addition, when the building management device starts monitoring or resumes monitoring of the building, or when monitoring is stopped, a transmission means is provided for transmitting a monitoring start signal, a monitoring stop signal, and various types of building information to the monitoring center. The removal or reset information is reflected in the database of the scheduled notification time, so that the scheduled notification is concentrated in a specific time zone, and the telephone line is congested and the load on the center device can be prevented.

Embodiment 2. FIG.
FIG. 6 shows the data structure of scheduled notification time management data stored in the storage means of the center device of the building remote monitoring system according to Embodiment 2 of the present invention. In the building remote monitoring system according to the second embodiment, the scheduled notification is performed every 24 hours, and the scheduled notification transmission prohibition band is set in the scheduled notification time management data. Although it is different from the remote monitoring system, the rest is the same, so the description of the same part is omitted.
As shown in FIG. 6, the scheduled notification time management data 41 stored in the storage means 11 of the center device 3 is assigned to the record (row) by the building management device 4 of the building 1 to be monitored. In the field (column), a building management apparatus number 32, a building name 33, a scheduled notification time 42, a start time 43 of a scheduled report transmission prohibited time zone, and an end time 44 of a scheduled report transmission prohibited time zone are assigned. The scheduled notification time 42 consists of one time per day because the scheduled notification is to be performed every 24 hours. In addition, the scheduled transmission prohibition time zone is a time zone in which remote maintenance work is planned for the building 1 from the remote center 2, or the telephone line 5 is used for other purposes depending on customer circumstances such as management of the building 1. Therefore, it is a time zone in which the transmission of scheduled notifications is prohibited.

Next, a procedure for processing the management apparatus information notified on a regular basis will be described with reference to FIG. FIG. 7 is a flowchart of a procedure for processing the management device information notified on a regular basis from the building management device by the center device. Steps other than step 201 and step 202 are the same as the steps in FIG.
In step 103, the time setting means 14 refers to the scheduled notification time 42 of each building after the current time from the scheduled notification time management data 41 stored in the storage means 11, and the scheduled notification times of any two buildings The intermediate time of the interval with the longest interval is taken as a candidate for the scheduled notification time of the building that made the scheduled notification time setting request. From the candidate times, the time most recently arrived from the present time is selected as the scheduled notification time of the building that has made the scheduled notification time setting request, and the process proceeds to step 201.
In step 201, the time setting means 14 determines whether or not the scheduled notification time selected in step 103 is included in a preset scheduled notification transmission prohibition time period, in the scheduled notification time management data 41. Referring to the start time 43 of the prohibited time zone and the end time 44 of the scheduled time message transmission prohibited time zone, if the selected time notification time is not included in the scheduled time message transmission prohibited time zone, the process proceeds to step 104, When the notification time is included in the scheduled notification prohibition time zone, the routine proceeds to step 202.
In step 202, the time setting means 14 determines the next next time from the present time when there is a time listed as a candidate for the scheduled notification time in step 103 at the same interval as the time included in the scheduled notification transmission prohibited time zone in step 201. The latest arrival time is selected as the scheduled notification time of the building that has made the scheduled notification time setting request, and the process returns to step 201. Also, if there is no time listed as a candidate for the scheduled notification time in step 103 at the same interval as the time included in the scheduled notification transmission prohibited time zone in step 201, the current time among the intermediate times in the next quiet time zone The latest arrival time is selected as the scheduled notification time, and the process proceeds to step 201.
In this way, it is possible to set the scheduled notification time excluding a specific time zone based on individual circumstances of the building.

  In such a building remote monitoring system, since the time limit notification transmission prohibition time zone of the customer building can be individually set in the scheduled notification time management data of the center device, the setting of the scheduled notification time reflects the circumstances of the customer building. Can be done flexibly.
