Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an alarm device for issuing an alarm when an abnormal state occurs in a monitored portion of a building.

[Prior Art] FIG. 2 is a block diagram showing an example of a conventional alarm device.

In FIG. 2, detection terminals A _{1 to} A _n for detecting the occurrence of an abnormal state are provided in monitored portions such as a vault, doors and windows, and fire alarms of a building.
With the abnormality detection of these detection terminals A ₁ to A _n, the terminal device 1 that is installed in the same buildings, abnormal point (e.g., vault) and the abnormal state type (e.g., intrusion) outputs information such as Then, the data is transmitted to the monitoring center 2 via the telephone line T and the telephone exchange 3 interposed in the telephone line T. Then, the monitoring center 2 transmits a signal indicating that the information has been received to the terminal device 1 via the telephone line T and the telephone exchange 3, and based on the information such as the abnormal location and the type of the abnormal state, for example, Immediately, appropriate measures are taken such as sending guards to the building. The monitoring center 2 centrally monitors a plurality of other terminal devices (not shown) together with the terminal device 1 described above.

[Problems to be solved by the device]

By the way, in the above-mentioned conventional alarm device, when an abnormal state of a monitored part, for example, illegal entry into the safe room occurs, the terminal device 1 immediately notifies the monitoring center 2 and then the safe room guard is sent. By the time of arrival, for example, usually 5
It takes about 20 minutes, but during this time there was a problem that it was impossible to deal with any abnormal conditions.

The present invention has been made in view of the actual situation in the prior art as described above, and its purpose is to identify a place and an abnormal state where the abnormality occurs when an abnormal state such as illegal intrusion occurs in a building. Accordingly, it is to provide an alarm device capable of repelling an illegal intruder.

[Means for Solving the Problems]

In order to achieve this object, the present invention provides a detection terminal for detecting an abnormal state of a monitored portion, and an abnormal point and an abnormal state where the abnormality occurs in association with the detection of the abnormal state of these detection terminals. In an alarm device having a terminal device that specifies the type and outputs information on the specified abnormal location and the type of the abnormal state, and a monitoring center that monitors information from this terminal device, A plurality of siren sound generators that are installed at predetermined positions and generate a siren sound, and are provided corresponding to the siren sound generators, and sequentially increase the volume of the siren sound generated from the siren sound generators from startup. A plurality of volume control devices, and a plurality of spins provided corresponding to the siren sound generation device and emitting a siren sound emitted from the siren sound generation device. Based on the information output from the terminal device, the driving order for driving the siren sound generation device corresponding to each speaker at predetermined time intervals is set, and the siren sound generation device is set in the set driving order. Output from the terminal device after a predetermined time corresponding to the time required for the patrol vehicle to arrive at the building that is empirically assumed from the time when the abnormal state is detected by the setting unit to be driven and the detection terminal. And a delay unit for outputting information to the setting unit.

[Action]

Since the present invention is configured as described above, when the detection terminal detects the occurrence of an abnormal state at the monitored location, the terminal device identifies the abnormal location and the type of abnormal state, and outputs this information. Then, the monitoring center that monitors the information from this terminal device takes appropriate measures according to the information. On the other hand, the alarm device provided in the same building as the terminal device, by the operation of the delay unit, from when the abnormal state is detected by the detection terminal until the patrol car reaches the empirically assumed building After a predetermined time corresponding to the time required, the information output by the terminal device is output to the setting unit. Based on the above information, the setting unit sets the operation order of the speakers installed at the predetermined positions, and the siren sound of the volume that is gradually increased from the start is emitted from each speaker in accordance with the setting order. Gatsu,
It is possible to immediately stop illegal activities by giving a psychological impact to a person who makes illegal intrusions as if a patrol car rushed to the scene.

〔Example〕

 Hereinafter, the alarm device of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the alarm device of the present invention. In FIG. 1, the same components as those shown in FIG. 2 described above are designated by the same reference numerals. In FIG. 1, the monitored terminals are provided with detection terminals A _{1 to} A _n, and speakers S _{1 to} S _n are installed at predetermined positions of the building. These speakers S _{1 to} S _n are , And is controlled by the control device 4. The control device 4 includes a delay unit 41 that delays information such as an abnormal location and an abnormal state from the terminal device 1,
A setting unit 42 that sets the driving order of the speakers S _{1 to} S _n based on the information, and a siren sound generation device 4 that generates a siren sound.
3, the volume control device 44 to increase sequentially from the drive volume of the siren sound, the driving unit 45 is provided for driving the speaker S ₁ to S _n.

The delay unit 41 described above is a predetermined time corresponding to the time required for the pilot vehicle to arrive at the building that is empirically assumed from the time when the abnormal state is detected by any of the detection terminals A _{1 to} A _n. Later, for example, after 20 seconds, the information output from the terminal device 1 is output to the setting unit 42.

A siren sound generator 43, a volume controller 44, and a drive unit
Reference numeral 45 is provided for each of the speakers S _{1 to} S _n .

In this embodiment, an abnormal state of the monitored part, for example,
When a trespass occurs in the vault, the detection terminal A _{1 in the} vault detects an abnormal condition. Based on the signal from the detection terminal A ₁ , the terminal device 1 identifies that an intrusion has occurred in the vault, outputs the identified information, and outputs the identified information via the telephone line T and the telephone exchange 3 to the monitoring center. Send to 2. Therefore, the monitoring center 2 is adapted to take appropriate measures such as immediately requesting a guard to be dispatched.

On the other hand, in the control device 4, the information such as the code signal of the safe room output from the terminal device 1 is output to the setting unit 42, for example, 20 seconds after the delay unit 41 described above. With the setting unit 42, the siren sound generator 43 repeatedly generates the siren sound from the _first selected speaker S ₁ , and the volume controller 44 sequentially increases the volume of the siren sound, while the passive unit 45 Drives speaker S ₁ . This control is repeated for the speakers S _{1 to} S _n sequentially selected by the setting unit 42, for example, at intervals of 5 to 10 seconds.

Follow go-between, the speaker S ₁ ~S _n is, though while several patrol cars sounded the siren, emitting such as whether approaching from a distance to該建creation.

As a result, the intruder in the vault runs away with surprise, so that illegal activities can be immediately stopped.

Note that the number of speakers can be reduced or increased as needed.

[Effect of device]

Since the present invention is configured as described above, the siren sound can be emitted after a predetermined time when the patrol car is supposed to arrive after the abnormality is detected. It has the effect of making you feel as if you have come and immediately stopping illegal activities.
