In the embodiment having such a configuration, when an abnormality is reported in a terminal device belonging to a certain block, the abnormality type discriminating unit T3, which is the discriminating means of the present invention, discriminates the type of abnormality, and the abnormality type is determined. In response to this, the selection control means of the present invention composed of the report destination selection unit T2 and the communication control unit T1 issues an abnormal report to the monitoring center 40 by either the direct report system or the general report system. In the embodiment, when a power failure accident occurs in the entire specific area due to heavy rain, the general warning system is used to report an abnormality to the monitoring center 40. It is set. In the alerting operation of this general alerting system, it is set so that the terminal device at the highest level of transmission of the anomaly notification in the block in which the power failure accident occurred generally issues an anomaly to the monitoring center 40. There is.

Here, in the information storage unit T5, preset types of abnormalities, individual numbers and telephone numbers of the terminal devices, telephone numbers of the monitoring center, information as to whether or not the lowest terminal device, and lower terminal devices are stored. The notification waiting maximum waiting time and the notification destination information for each abnormality information are transmitted from the monitoring center 40 and stored as described later. Also, the monitoring information input unit T4
Indicates that an error has occurred in the equipment S1 to Sn.
Has a function of inputting an abnormality notification signal to the abnormality type determination unit T3, and the abnormality type determination unit T3 is set in advance in which the abnormality of the notification signal is stored in the information recording unit T5. It also has a function of determining whether or not it is an abnormality (in the embodiment, a power failure accident in the entire specific area).
Further, the report destination selection unit T2 has a function of determining the report destination according to the type of abnormality, and the communication control unit T1 has a function of determining the report destination.
It has a function to take out the report destination telephone number from 5 and perform automatic dialing. Then, the reception information determination unit T6
Has a function of determining whether or not the abnormality is a preset abnormality when the abnormality is reported from the lower terminal device to the upper terminal device by the area transmitting means.

Next, the operation of the embodiment having such a configuration will be described.
With respect to a power failure accident in the entire specific area, a case will be described with reference to the flowchart of FIG. 3 in which a general alert system is set to issue an abnormal alert to the monitoring center.

In the embodiment, if an abnormality occurs in the equipment installed in the building and the terminal device 1-n detects the abnormality, the monitoring information input unit T4 of the terminal device 1-n is detected in step S1. , The abnormality is detected by the signals from the sensors S1 to Sn, the process proceeds to step S2, and the abnormality type determination unit T
3, it is determined whether the generated abnormality matches the abnormality stored in the information storage unit T5 in advance. If the determination in step S2 is NO, an abnormal alarm is issued by the direct alarm method. In this case, step S
12, the reporting destination selection unit T2 selects the monitoring center 40 as a reporting destination, and the communication control unit T1 reads the telephone number of the monitoring center 40 from the information storage unit T5 and performs an automatic dial operation. From the terminal device 1-n to the telephone line L1
An alarm is directly issued to the monitoring center via the, and the process proceeds to step S6 to end the information transmission.

On the other hand, if the abnormality that has occurred is a power failure accident and the determination in step S2 is YES, then an abnormality is issued by the general alert system. In this case, the process proceeds to step S3, and the terminal device 1-
It is determined whether n is the lowest terminal device,
The terminal device 1-n is the lowest terminal device in block 1, and the determination in step S3 is YES. Therefore, the process proceeds to step S4, and the communication control unit T1 moves from the information storage unit T5 to the higher terminal device 1-m. The telephone number of the host computer 1 is read out, the automatic dialing operation is performed, and the higher-level terminal device 1 is connected through the area telephone line L0.
-M is notified that a power failure has occurred in the terminal device 1-n. Next, in step S5, the communication control unit T
1 determines whether or not the notification has been accepted. If the determination is YES, it is determined that a power failure has occurred in the entire area of block 1, and the process proceeds to step S6 to end the information transmission. If the determination in step S5 is NO, it is determined that a power failure has occurred in the building in which the terminal device 1-n is installed, and the reporting destination selection unit T2 switches the reporting destination to the monitoring center 40. , The terminal device 1-
An abnormality is reported from the n to the monitoring center 40, and the process proceeds to step S6 to end the information transmission.

For example, when the terminal device 1-5 detects a power failure accident and the determination in step S3 is NO, the process proceeds to step S7 and waits for the reception of an abnormality notification from the lower terminal device 1-6. When there is a notification of abnormality from the lower terminal device 1-6 via the area telephone line L0 and the communication control unit T1, and the determination in step S7 is YES, the process proceeds to step S8.
In step S8, the reception information determination unit T6 determines whether the notification of the abnormality from the lower-order terminal device 1-6 matches the abnormality stored in the information storage unit T5 which is set in advance. If YES, step S9
The process goes to step S4 to store the notification of the abnormality from the lower terminal device 1-6 in the information storage unit T5, and the process proceeds to step S4 to the next higher terminal device 1-4 to notify the own error to the lower terminal device 1
-Abnormalities are reported by adding abnormalities from 6-1 to 1-n.

If the determination in step S8 is NO and the abnormality notification is different from the preset abnormality information, the process proceeds to step S10 to reject the reception of the received information, and in step S11 the lower terminal device 1-6 again. If there is no notification within a predetermined time after waiting for a notification of an abnormality from the lower terminal device 1
It is judged that no abnormality has occurred in -6 to 1-n,
In step S4, an abnormality is reported to the next higher order terminal device 1-4. Even if the determination in step S7 is NO and there is no notification of abnormality from the lower terminal device 1-6, the process proceeds to step S11 and waits again for notification of abnormality from the lower terminal device 1-6.

On the other hand, in step S1, although the terminal device 1-5 of its own has not detected an abnormality, step S1
If it is determined that the information is received in step 3, step S
It is determined at 14 whether the information is from the lower terminal device 1-6. If the information is from the lower terminal device 1-6, the process proceeds to step S15, and the acceptance of the information is rejected. If the determination in step S14 is NO, the information is transmitted from the monitoring center 40 and the information storage unit T5 of the terminal device 1-5.
Since it is the information stored in step S1, step S1
In step 6, the information is stored in the information storage unit T5.

In the embodiment, since the abnormality is reported in this way, if a power failure accident occurs in the area of block 1, the terminal devices 1-7 to 1-7 ... In response to a power failure abnormality notification of 1-n, the terminal device 1-7 collectively reports a malfunction to the monitoring center 40 via the telephone line L1, and the power failure of the terminal devices 1-1 to 1-5. Regarding the notification, the terminal device 1-1 collectively issues an abnormality report to the monitoring center 40 via the telephone line L1, whereby an abnormality is issued by the overall issue system.

As described above, according to the embodiment, when a power failure accident which has been set as a predetermined malfunction occurs in advance, an abnormal alarm is issued by the general alert system, and the area telephone line is provided in the block where the power failure accident occurs. By L0, the notification of the abnormality is sequentially transmitted from the lower terminal device that has detected the power failure accident to the upper terminal device, and it is confirmed that the power failure accident has occurred in a wide area of the block. And area telephone line L0
In the terminal device of the highest level of transmission of the notification in (1), the frequency of reporting is reduced and the abnormality is generally reported to the monitoring center 40 via any of the telephone lines L1 to Lm. Therefore, there is no possibility that the telephone lines L1 to Lm are in use due to abnormal alarms of wide-area power outages that are concentrated in time, and that the notification to the monitoring center 40 is delayed or missed. For example, even if a wide area power outage occurs in an area with hundreds of terminal devices,
If this terminal area is divided into a plurality of blocks of dozens of terminal devices, the number of terminal devices reporting to the monitoring center 40 will be more than ten. Therefore, the number of waiting lines of the monitoring center 40 is sufficient for reception. It is possible to In addition, if a more urgent abnormal situation such as an elevator canning accident occurs at the time of a wide area power outage, the telephone lines L1 to L are connected from the terminal device.
The abnormality is directly notified to the monitoring center 40 through the m via m, and the abnormality is notified of an abnormal situation with a high degree of urgency at the time of occurrence of a wide-area power outage that is concentrated temporally. Even if there is, the monitoring center 40 can receive it promptly and without omission.

[0022]

As described above in detail, in the present invention, when an abnormality occurs, the determining means determines the type of abnormality,
Depending on the determined type of abnormality, either the direct reporting method or the general reporting method is selected by the selection control means, and the monitoring center is notified by the selected method.
For abnormalities with a high degree of urgency, the direct alarm system directly issues an abnormal alarm to the monitoring center via the telephone line from the terminal device that detected the abnormal condition, and the abnormal alarm is concentrated temporally. With regard to abnormalities such as wide-area power outages that occur accidentally, a general alert system is used to reduce the frequency of alerts from the terminal device at the top of the area transmission means to the monitoring center via the telephone line. Abnormal alarm is issued.
In this way, the frequency of reporting abnormalities in which alerts are concentrated temporally is reduced, so that the telephone line between the terminal device and the monitoring center is in use and the alert cannot be received by the monitoring center. It is possible to prevent the occurrence of a delay or a delay and to promptly and surely receive the alarm report of high urgency at the monitoring center, and to quickly recover the abnormality of high urgency.
