Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a security system for protecting factories, general offices, etc. from theft, fire, etc.

[Conventional technology]

Traditionally, security systems that operate unmanned security systems using communication lines install detectors to detect theft, gas leaks, fire, etc. in designated security areas such as factories and offices, and detect abnormalities. When this happens, an alert is sent to the security monitoring center via the terminal device, and the security monitoring center instructs the business to take necessary steps. Such a configuration will be explained using figures.

FIG. 2 is a block diagram of a conventional security system. In the figure, IA to IB are security monitoring centers that have jurisdiction over areas A and B, respectively, and 2ax to 2an are areas a1 to a, respectively.
This is a business office that manages n.

3az to 3an are factories located within areas 81 to arl, respectively, and managed by business establishments 2az to 2an.

Indicates a terminal device installed in an office, etc.

For example, when a theft occurs in an office equipped with a terminal device 3an, the terminal device 3an sends an alarm to the security monitoring center IA via a communication line, and the security monitoring center IA, which receives the alert from the terminal device 3an, sends an alert to the terminal device 3an. A request is made for a security guard to be dispatched to the office equipped with the terminal device 3an that sent the alarm to the office 2an in the area a7 where the device 3an is installed. The dispatched security guard enters the dispatch light's alarm generating office and performs an alarm cancellation operation on the terminal device 3a at the start of Wl1 work. Here, the terminal device 3 a n transmits an alarm cancellation signal to the security monitoring center IA, reports the arrival of the security guard, and cancels the security.

[Problem that the invention seeks to solve]

In the conventional security system described above, the communication line between each terminal device and the security monitoring center is normally checked periodically every few hours. By the way, if the communication line between the terminal device 3an and the security monitoring center IA breaks down and theft occurs before this is checked, the terminal device 3an will not be able to send this to the security monitoring center IA. The problem was that it became impossible to take necessary measures.

An object of the present invention is to eliminate the drawbacks of the above-mentioned prior art, and to make it possible to send an alarm from a terminal device to a security monitoring center even if a failure occurs in a communication line, thereby improving the reliability of security. The purpose is to provide a security system.

[Means for solving problems]

In order to achieve the above object, the present invention provides a communication system that connects a security monitoring center and a terminal device of a building under the jurisdiction of this security monitoring center, and between the security center and the monitoring business hours that manage the building. , when the alarm in the terminal device of the building is not canceled for a predetermined time,
Another communication system is provided for transmitting an alarm signal from a terminal device in the building to the security monitoring center via a management system located outside the security monitoring center.

[Effect]

When the alarm of the terminal device is not canceled for a predetermined period of time, the terminal device is provided with another communication system that transmits an alarm signal to the security monitoring center via a management system located outside the security monitoring center. As a result, even if a failure occurs in the communication line between the terminal device and the security monitoring center, the alarm from the terminal device can be sent to the security monitoring center via a management system other than the security monitoring center, increasing the reliability of the security system. Improvements can be made.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a security system according to an embodiment of the present invention. In FIG. 1, the same parts as in FIG. 2 are designated by the same reference numerals, and their explanation will be omitted. In this embodiment, a communication line is provided between a required terminal device and the security monitoring center IB in another area B, and a communication line between the security monitoring center IB and the security monitoring center IA.

Now, if a theft occurs in an office equipped with the terminal device 3an, the terminal bag [3a, sends a security signal to the security monitoring center IA, but the communication line between the terminal device 3an and the security monitoring center IA is If the alarm signal cannot be sent to the security monitoring center IA due to a malfunction, the terminal device 3
an transmits an alarm signal to a security monitoring center IB other than the one in charge of alarm signals when a predetermined period of time or more has elapsed since the start of the theft.

Next, the security monitoring center IB that received the alarm signal from the terminal device 3an transmits the alarm signal of the terminal device 3an to the security monitoring center IA that has jurisdiction over the terminal device 3an, and theft occurs in the office equipped with the terminal device 3an. and have the Security Monitoring Center IA take necessary action. Thereby, even if the communication line between the terminal device 3an and the security monitoring center IA is out of order, it is possible to reliably notify the security monitoring center IA of the occurrence of theft.

In addition, in the explanation of the above embodiment, in the case of a communication line failure, an example was explained in which an alarm signal is transmitted via a security monitoring center outside the jurisdiction, but it is not limited to this. Alternatively, it may be a business office within the jurisdiction.

〔Effect of the invention〕

In the present invention, when the alarm of a terminal device is not canceled for a predetermined period of time, this alarm is transmitted to the security monitoring center through a management system other than the security monitoring center that has jurisdiction over the terminal device. Even if a failure occurs in the communication line between the security monitoring center and the security monitoring center, the security monitoring center can be notified of the occurrence of an alarm.

Claims (1)

[Claims] 1. In a communication system that communicates between a security monitoring center and a terminal device in a building under the jurisdiction of this security monitoring center, and between the security center and a monitoring office that manages the building, an alarm in the terminal device in the building is transmitted. A security system comprising another communication system that transmits an alarm signal from a terminal device in the building to the security monitoring center via a management system other than the security monitoring center when the alarm is not released for a predetermined period of time.
