Detects the occurrence of anomalies such as the intrusion of a thief, and automatically sends information on the occurrence of anomalies detected by these sensors, security mode information such as security set and release to a remote monitoring center, etc. using a telephone line. There is an automatic information transmission device to perform.

[0003]

In these conventional automatic information transmitting apparatuses, when a customer who contracts with a security company is in a security target area, an abnormality may occur in the security target area. In such a case, if the detection by the various sensors is performed earlier than the abnormality detection by the customer, the various information detected by the sensors is reported to the monitoring center via the telephone line, so that the monitoring center can quickly respond to the abnormality.

[0004] However, in some cases, it may happen that the abnormality detection of the customer is earlier than the detection by the sensor. In such a case, the customer usually reports to the fire department or the police using a telephone. Even if the customer discovers the abnormality before the sensor detects the abnormality,
Since the conventional automatic information transmitting apparatus detects the occurrence of an abnormality only by a sensor, the monitoring center cannot grasp the occurrence of the abnormality having an urgency until the notification is made by the sensor. Therefore, there is a possibility that a measure corresponding to the abnormality in the monitoring center is delayed.

According to the present invention, in an automatic information transmitting apparatus using a telephone line, when an abnormality is discovered by a customer before the sensor detects the abnormality, the occurrence of the abnormality is reported to a monitoring center before the abnormality is detected by the sensor. An object of the present invention is to enable the monitoring center to quickly grasp the occurrence of an abnormality in a security target area by enabling the monitoring center.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above object. The present invention relates to an automatic information transmitting apparatus for transmitting abnormality occurrence information to a remote monitoring center using a telephone line. In the automatic information transmission apparatus, an abnormality is discovered by a customer before a sensor detects the abnormality. , It is detected that this customer has made a call, and this is automatically transmitted to the monitoring center.

In order to execute this, the present invention relates to an automatic information transmitting apparatus for transmitting abnormality occurrence information to a remote monitoring center using a telephone line, wherein a destination of a telephone connected to the automatic information transmitting apparatus is previously determined. Call destination determination means for determining whether or not the call destination is a specified call destination, and when the call destination determination means determines that the call destination of the telephone is a predetermined call destination, the monitoring center is notified. Te, provided transmitting means for sending a signal indicating that the telephone is in the pre-designated call destination.

[0008]

Each time the telephone is used, the destination determining means constantly checks whether the destination of the customer's telephone is a predetermined destination, for example, a fire department or police.
Then, when it is detected that a call has been made to the called party specified by the customer, a signal indicating that a report has been made to the fire department or the police is transmitted to the monitoring center.

Thus, even if the abnormality detection by the various sensors is later than the abnormality detection by the customer, the monitoring center can quickly grasp the occurrence of the abnormality in the security target area before the detection by the sensors.

The transmission means 11 is connected to the monitoring center 26 under the control of the network control means 10, and the sensor interface 13 and mode detection means (not shown)
Transmits transmission information such as fire abnormalities, mode change information, and destination information. Next, the operation of the automatic information transmitting apparatus 1 shown in FIG. 1 will be described in detail below with reference to the flowchart shown in FIG.

Normally, the relay switch 6 of the line switching means 6
a and 6b are switched to the destination identification means 2 side, and the telephone 21 is connected to the telephone line 23 via the telephone line 22, the destination identification means 2 and the line switching means 6, and the telephone 21 It is in a usable state. The user is the telephone 2
Dialing is performed using No. 1 (step S11). The dial pulse generated at this time is transmitted to the telephone line 23 via the destination identification means 2. At this time, the destination identification means 2 counts the dial pulse, identifies the telephone number of the destination, and stores the telephone number via the network control means 10.
4 is stored (step S12). Here, every time a dialing is performed, the contents of the storage means 14 are updated to the latest telephone numbers.

Next, the line network control means 10 executes step S
The telephone number identified in 12 is a predetermined number, for example, 110,
It is determined whether the designated telephone number is 119 or the like (step S13). If it is determined that the telephone number is not the designated telephone number, the operation ends. When it is determined that the telephone number is the designated telephone number, the line network control means 10 detects the state of the telephone line 23 by the line state detecting means 3. Here, when the telephone 21 is talking, a current flows through the telephone line 23, and the photocoupler 4a or 4b operates to detect that the telephone line 23 is being used. If the use of the telephone set 21 is detected, the line state is detected again, and this operation is repeated until the call ends (step S14).

In this embodiment, the line state is always detected. However, the line state may be monitored at regular intervals, and the process may proceed to the next step when the call is completed. When the telephone call ends, no current flows through the telephone line 23, so that the photocoupler 4a or 4b of the line state detecting means 3 does not operate, and it is detected that the telephone line 23 is not used. Telephone line 23
When the telephone is not in use, that is, when the telephone call ends and the telephone 21 goes on-hook, the dial control means 5 sets the telephone line 2

Dial the telephone number of the report destination such as, and turn off the shunt relay 7
(Step S17). When the monitoring center 26 responds,
A response signal is returned from the monitoring center 26. And
When the response signal is received by the response signal receiving means 12 (step S18), the transmission means 11 sends out a signal indicating that the user has talked to the designated destination (step S19). This signal is, for example, an emergency notification signal in the case of the number 110, and fire information in the case of the number 119. This signal may be a special signal such as a special 110th report end signal or a 119th report end signal.

By receiving these signals, the monitoring center 26 can quickly and reliably know that at least an abnormality has occurred in the installation location of the automatic information transmitting apparatus 1. Then, a reception confirmation signal is transmitted from the monitoring center 26 to the automatic information transmission device 1. In the automatic information transmitting apparatus 1, the response signal receiving means 12 receives the acknowledgment signal (step S20).
And the line network control means 10 is a dial pulse relay / line.
The closing relay 8 is operated to turn off and open the line (step S21). Then, by switching the relay switches 6a and 6b of the switching means 6, the telephone line 23 is switched from the automatic information transmitting apparatus 1 to the telephone line 22, that is, the telephone 21 (step S22), and the operation is terminated with the telephone 21 in a usable state.
