Field of the Invention The present invention relates to an abnormality notifying device for automatically notifying a monitoring station, that is, a security headquarters, of abnormal information or security mode information using multi-party communication when the information is generated.

[0002]

2. Description of the Related Art In a conventional abnormality reporting device, for example, as shown in JP-B-63-37549, when an abnormality occurs, for example, when a fire occurs, gas leaks or other abnormal conditions occur, an abnormality report is made. In the case where the telephone set of the subscriber to whom the device is attached is in a busy state, a method has been proposed or implemented in which the telephone line is forcibly disconnected and the abnormality information is promptly reported to the security headquarters.

[0003]

However, in such a conventional system, since the communication line is temporarily disconnected when reporting the abnormal information, if the requirements for the telephone call with the other party are not terminated, the abnormal condition may occur. After the signal is transmitted to the security headquarters, there is a problem that it is troublesome to call the other party again. Further, there is a problem that a dedicated telephone line needs to be provided to avoid such trouble.

[0004] The present invention has been proposed to solve the above-mentioned problems, and it is an object of the present invention to utilize a multi-party call to disconnect abnormal information without disconnecting the telephone line of the other party. Another object of the present invention is to provide an abnormality reporting device that automatically reports security mode information to a security headquarters.

[0005]

One aspect of the present invention is an abnormality reporting device for sharing a telephone line with other equipment and reporting call request information such as abnormality information and security mode information to a monitoring station.

According to the above means, when the abnormality information is reported to the monitoring station, the busy state of the telephone line is detected by the busy detecting means. When those該回line is busy state is activated multi-way calling means, the line currently busy is temporarily suspended. At such time, the notification line is formed by the automatic calling means. Then, after completion of the report, the previous line held is restored by the multi-party communication means.

[0007]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention. In FIG. 1, an abnormality notification device according to the present invention includes a sensing means 1 which is a call request information detecting means for sensing a setting state of a security mode and an abnormality such as a fire or an intrusion, and a notification based on a signal of the sensing means 1. A determination activation unit 2 for determining whether or not the telephone line is necessary and transmitting an activation signal; an identification unit 3 for identifying whether the telephone line is empty or busy and transmitting an activation signal;
Busy detection means 4 which is activated when the line is busy, multi-party communication means 5 for forcibly forming a multi-party communication line based on the activation signal from said identification means 3, dial pulse signal to the security headquarters Automatically calling means 6 for automatically calling the security headquarters, response detection means 7 for detecting a response signal returned when the security headquarters is called and the security headquarters responding, and a detection signal of the response detection means 7 And a response unit 8 that encodes the type of abnormality that has occurred or the security mode set by the switching operation device 11 to the security headquarters and sends it.

[0009] The sensing means 1, for example, a switching operation unit 11 switching it insertion and sampling Ri to result security start or security release of a given card is performed by the subscriber owned,
A security status setting circuit 12 that reads this information and sets a security status;
Various abnormality detection sensors 13a, 13b... 13n for detecting intrusion using a microswitch or the like, fire detection, etc.
Detection circuits 14a, 14b... 14 for detecting a predetermined level abnormality in the signal of the abnormality detection sensor and transmitting the signal.
n.

The operation of the abnormality notification device according to this embodiment will be described together with the detailed circuit configuration of each unit (means). When a predetermined card possessed by the subscriber is inserted or removed from the switching device 11 in the sensing means 1, the signal is sent from the security state setting circuit 12 to the automatic calling means 6 via the predetermined determination section 21 and the start switch 22. Sent. Such a signal is reported to a security headquarters (not shown) via a telephone line, and the security headquarters knows from the transmitted signal that the place where the abnormality notification device is attached has reached the security start time. Similarly, in the case of security release, the security headquarters knows that the installation site is under security release by a signal transmitted according to insertion or removal of a card. However, in the case of an abnormality report due to a fire and an emergency report, the decision section 21 of the decision activation means 2 operates even when the security is being released, and can report the abnormality to the security headquarters.

[0011] In the judging section 21, a start signal due to intrusion detection is not output to the start switch 22 while the security is released.

First, the operation when an abnormal situation occurs when the telephone line is empty will be described. For example, the abnormality detectors 13a, 13b of the detecting means 1 for detecting intrusion.
13n senses an abnormality, the judgment activating means 2
Is sent to the determination unit 21 to determine whether the current mode is during the guard time or during the security release.

During the guard time, the high-level signal from the start switch 22 is supplied to the AND gates G1 and G of the identification means 3.
2 is sent to one input of each. On the other hand, telephone line L
Since L1 and L2 are empty, the relay OH of the busy detection means 4 is not activated, and the output of the busy detection means 4 is high. Accordingly, the two inputs of the AND gate G2 are both at a high level, and the output thereof is also at a high level. In the AND gate G1, since the inverter 31 is inserted between the output of the busy detection unit 4 and The output becomes low level and is not output.

The high-level output of the AND gate G2 activates the dial pulse generating circuit 6, which is an automatic calling means, activates the line closing relay A, the dial pulse relay DI, and the shunt relay DS.
1, a2, the contact DI of the relay DI and the contact ds of the relay DS are turned on, so that the DC closed loop L1-
a1-di-ds-a2-L2 is formed.

Thereafter, a predetermined dial pulse signal (for example, a telephone number of a security headquarters) stored in advance in the dial pulse generating circuit 6 activates the contact di of the dial pulse relay DI, thereby causing the DC closing loop Dialed to the Security Headquarters through. The security headquarters is called by this dial pulse signal. When the security headquarters responds, a response signal is returned to the abnormality notification device. When this response signal is detected by the response detection means 7, the information signal selection switch circuit 81 of the response means 8 operates,
Various coded abnormality information based on a combination of signals corresponding to the type of abnormality of the abnormality sensor stored in the signal generating circuit 82 in advance is transmitted. At the same time, the information transmission switching relay C is operated, the contact c is switched, and the abnormality information is transmitted to the security headquarters through the telephone lines L1 and L2.

This allows the security headquarters to know the type of abnormality that has occurred. After transmitting the abnormal information, the information transmission switching relay C is restored, and at the same time, the DC closed loop is opened.

Next, the operation when the telephone lines L1 and L2 are busy will be described. As described above, when the abnormality detector of the sensing means 1 detects an abnormality, a high-level activation signal is sent to the identification means 3 by the determination activation means 2. Busy detection means 4
The relay OH 1 is activated because the telephone line is busy, and its contact oh is on, so that the output of the busy detection means 4 is low. Since the inverter 31 is inserted between one input of the AND gate G1 and the output of the busy detection means 4, both inputs of the AND gate G1 are at a high level, and the output is also at a high level. . On the other hand, the two inputs of the AND gate G2 are at low level and high level, respectively, and the output is at low level and is not output.

The high-level output of the AND gate G1 activates the multi-party communication circuit 5 as multi-party communication means. That is, the multi-party communication circuit 5 operates the dial pulse generation circuit 6 to switch the contacts a1 and a2 to the abnormality notification device side. At this time, the dial pulse relay DI and the shunt relay DS are set to be turned on, and the DC loop L1-contact a1-contact di-contact ds-contact a
2-L2 is formed.

Next, the dial pulse generating means 6 operates the dial pulse relay DI to turn off the contact di once and immediately turn it on again. As a result, it becomes possible to call the report destination via the telephone lines L1 and L2 without disconnecting the line during the call.

Thereafter, by operating the contact di of the dial pulse relay DI, a dial pulse signal is transmitted to the security headquarters.

The security headquarters is called by the dial pulse signal, and a response signal is returned to the abnormality notification device when the security headquarters responds. This response signal is sent to the response detection circuit 7
Is detected by Then, the information signal selection switch circuit 81 of the response means 8 is operated, and various coded abnormality information is stored in the signal generation circuit 82 by combining a signal corresponding to the type of abnormality of the abnormality sensor. Is sent. At this time, the information transmission switching relay C is operated at the same time,
The contact c is switched, and the abnormality information is sent to the security headquarters through the telephone lines L1 and L2. This allows the security headquarters to know the type of abnormality that has occurred. After sending the abnormal information,
The information transmission switching relay C is restored.

Next, the dial pulse relay DI is connected to the contact d.
i is operated, and the contact di is repeatedly turned off and on twice.
As a result, the DC closing loop with the security headquarters is opened. However, since the telephone line with the talking party is closed as it is, the call can be continued thereafter.

In the embodiment of the present invention, for example, a message such as "Please wait" may be sent to both callers before the other party talks.

Although the embodiment has been described with reference to the dial system, it is needless to say that the invention can also be applied to a push-phone system. Further, the call request information is described as security mode information and abnormality information, but may be only security mode information or abnormality information.

The response means 8 is activated by a response signal from the security headquarters. Alternatively, the response means 8 may be activated by detecting inversion of the line polarity due to off-hook of the security headquarters.

[0026]

According to the present invention, even if the telephone line is busy, the occurrence of an abnormality can be reported to the security headquarters without disconnecting the telephone line, so that the security level is improved.
In addition, there is no danger of intentionally putting a line busy and causing damage during that time, which is effective for disaster prevention. Further, when it is necessary to continue a call, there is an effect that it is not necessary to call the other party again. Further, there is an advantage that it is not necessary to provide a dedicated telephone line for such notification.
