[0009]

The present invention will be described in detail below with reference to examples.

FIG. 1 is a plan view of a building structure to which the present invention is applied.

Normally, a plurality of fire extinguishers 4 are installed for one building structure 1, but the installation locations are such that the distances between the fire extinguishers closest to each other are within the legal distance specified by the Fire Service Law. On the other hand, the building structure 1 is generally provided with partitions of complicated structure, walls, doors, furniture and devices inside, equipment, etc., and it is common to arrange fire extinguishers regularly. Since it is not easy, the fire extinguisher 4 is installed as the means 5 for identifying the presence or absence of the fire extinguisher 4 which is often arranged as shown in FIG. 1 in reality. To be done. This fire extinguisher identification means 5
Then, the existence state of the fire extinguisher 4 is, for example,
The weight of the fire extinguisher is detected by a weight scale, an ultrasonic sensor, or by optically detecting the weight of the fire extinguisher. It is sent to the central control device 2 of the fire extinguisher via the display device and displayed on the display device 6 in the building structure 1.

FIG. 2 illustrates an apparatus for optically detecting the presence or absence of a fire extinguisher as the fire extinguisher identifying means used in this embodiment. An electric cable 9 is used as a light emitting element (laser diode) 7, a light receiving element (photodiode) 8, and a signal transmitting means.

In FIG. 2, if the fire extinguisher 4 is installed at a predetermined position, the fire extinguisher 4 serves as a light shield, and the light receiving element (photodiode) 8 is an optical signal from the light emitting element (laser diode) 7. Fire extinguisher 4
When is removed from the predetermined position, the light receiving element (photodiode) 8 detects the optical signal from the light emitting element (laser diode) 7, and this electric signal is transmitted through the signal transmission means 3 to the display device at the central control point of the fire extinguisher. 2 and is displayed on the display device 2. As described above, the signal transmitting means 3 usually handles electric signals in many cases, but depending on the surrounding environment, an optical signal transmitting method using an optical fiber cable or a wireless signal transmitting method may be used. In the optical detection method of the fire extinguisher 4 by the light, as shown in FIG.
In addition to the method shown in, a part of the mirror surface of the body of the fire extinguisher 4 (the mirror surface if not already installed) is used,
It is also possible to use a light emitting and receiving composite element or the like that detects reflected light from here.

In addition, since it is generally difficult to identify the location of a fire in advance, information from the centralized control device 2 is displayed at a plurality of locations for risk distribution, for example, as shown in FIG.
A display panel 10 showing the position of the fire extinguisher in the building structure 1, an input device 12 for inputting information such as an expiration date of the fire extinguisher and an individual fire extinguisher or a fire extinguisher at the time of fire. A display panel 11 for displaying information and the like, and a plurality of display devices 6 for displaying the presence or absence or status of each type of fire extinguisher by displaying symbols or colors for each type of fire extinguisher. Installation is effective.

The fire extinguisher includes a foam type, a freon gas type,
There are many types such as carbon dioxide gas type, powder type, etc., each with different purposes, uses, and performances, but depending on the target building structure 1, multiple types of fire extinguishers may be installed. In this case, in this case, the type of fire extinguisher is registered and stored in advance in the central control device 2 of the fire extinguisher, and the display device 6 displays a symbol or a color depending on the type of the fire extinguisher. It is effective to display the presence / absence of each type of fire extinguisher by displaying it.

Further, since a fire extinguisher usually has an expiration date, this information can also be registered by registering it in advance in the central control device 2 of the fire extinguisher each time the fire extinguisher is updated. It is possible to manage the fire extinguisher through the display device 6. In addition, the fire extinguisher whose expiration date is approaching will notify the administrator of the approaching expiration date and the necessity of countermeasures by blinking the display of the extinguisher from a certain period (for example, one month) before that. It is also possible.

[0017]

As described above, by using the fire extinguisher management system of the present invention to manage a large number of fire extinguishers over a wide area, it can be used even in an emergency situation such as a fire. It is clear from time to time how many fire extinguishers are left, so this information is sent to people engaged in fire fighting activities based on the indication from the central control unit, and it is also broadcasted through broadcasts, etc. As a result, quick collection of fire extinguishers and fire fighting activities are possible, and in the event of a fire, the power is exerted in the particularly important initial fire fighting activities. That is, a plurality of fire extinguishers are collectively managed, and the location of the fire extinguisher and the presence or absence of the fire extinguisher in an emergency such as a fire occurrence,
It is possible to inform those engaged in fire fighting activities of the type of fire extinguisher, the expiration date of the fire extinguisher, etc. as quickly and accurately as possible so that appropriate and effective fire fighting activities can be realized.
