Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disaster prevention alarm system, and more particularly, to a fire prevention alarm system for a fire.

[0002]

2. Description of the Related Art For example, a disaster prevention system such as a factory, a large-scale hospital, a university, or various facilities having many distributed and existing buildings on the same premises has the following configuration. I have.

That is, a P-type receiver (automatic fire alarm) is provided in each building, and a general receiver for catching a transfer signal from the P-type receiver is provided, for example, in a security room. The portable receiver and the general receiver are connected by a dedicated line, so that the security room can manage the disaster prevention of all the buildings at once.

[0004] The P-type receiver is a building,
It is connected to the sensors in the guard area that is appropriately divided in each level, so that when a fire occurs, it is possible to know from which floor and which guard area the fire broke out.

[0005] However, in the conventional disaster prevention alarm system, it is immediately known in which security building the fire originated from the security room, but further information is obtained by the security guard rushing to the target building and displaying the P-type receiver. I did not understand until I saw.

Conventionally, as a layout drawing of a building on a premises, a model of a building made of a wooden mold or the like has been pasted on a display board (a graphic board of a building on the premises).

[0007] When the building is demolished, a model of the corresponding building is taken from the display panel, or when the external shape of the building changes, a model having a shape corresponding to the model is created and pasted.

[0008] Further, since the hierarchies were recreated each time, management was extremely difficult.

On the other hand, the display board is indispensable for explaining when a fire station is dispatched.

[0010]

In recent years, disaster prevention systems have been modernized with the development of communication systems and electronic technologies, and a large-scale disaster prevention system capable of projecting the situation of a fire site on a CRT monitor for monitoring has been proposed. Have been.

Such a system includes, for example, a general receiver called an R-type, connects a P-type receiver provided in each building to the R-type general receiver by a dedicated line, and also connects a corresponding building to the building. Is captured via a monitor camera that can be driven by remote control, and disaster prevention information and an image of the site are displayed on a CRT monitor for monitoring.

The disaster prevention system can immediately identify the site where the above has occurred on the CRT monitor, and can easily and instantly know the status of the site. Therefore, the problem of the conventional disaster prevention system can be sufficiently compensated.

[0013] However, such a disaster prevention system is suitable when a new building is newly constructed,
As mentioned above, when trying to provide the same usefulness as above for existing buildings, a new comprehensive receiver,
Not only is a receiver required, but also a new laying of a dedicated line connecting the general receiver and the receiver is required.

[0014] However, new equipment, for example, an R-type integrated receiver is extremely expensive, costing tens of millions of yen.
Even if a dedicated line is laid, it is similarly expensive, so that the economic burden in introducing the system is large.

Further, for example, even if a dedicated line already laid is sufficiently durable for use, the disaster prevention system is one product for the manufacturer, and a useful disaster prevention system as described above is newly constructed. If so, it couldn't be used as a result, even if you wanted to use it.

This leads to a disadvantage that resources and economical waste are generated.

The present invention has been made in view of the above points, and its object is to use equipment used in an existing building or a dedicated line, and to immediately provide information on a target building when an abnormality occurs. It is to provide a disaster prevention system that can be obtained in a country.
