Description

[Detailed Description of the Invention] The present invention relates to a fire display device that displays the location of a fire based on fire information from a fire detector.

Traditionally, fire alarm equipment installed in buildings, etc.
A large number of fire detectors are installed on every floor in each warning area, and detection information from the fire detectors is received by a central receiver for centralized monitoring. In such a fire alarm system, it is necessary to promptly and accurately display the location of an emergency fire, such as the name of the district where the fire occurred and the floor on which the fire district is located.

With conventional fire display devices that display the location of a fire, the area name is displayed in text on an illuminated nameplate, and nameplates are provided corresponding to the area names for all floors. A nameplate with the name of the area corresponding to the area where the fire occurred was illuminated to indicate the location where the fire occurred.

However, as the number of warning zones in which fire detectors are installed increases in buildings, etc., the number of nameplates displaying district names also increases, so the problem arises that the cost of the fire display device increases due to the larger display area. It was hot.

For this reason, we set a unique number corresponding to the name of each district, and use a number display that displays the number to display the number corresponding to the district where the fire occurred based on the fire information from the fire detector. Fire indicator devices have been proposed that are designed to be smaller.

However, with this type of numerical display, it is necessary to determine the district name from the displayed numbers.
Confirming the location of the fire took time and was complicated.

Furthermore, based on the fire information from the fire detector,
A text display that displays information in written text, a map such as a floor plan or cross-sectional view of a building, and light emitting diodes, etc. are placed on the map corresponding to the warning area where fire detectors are installed. Fire display devices have been proposed that are equipped with light-emitting elements and display the location of a fire by causing the corresponding light-emitting elements to emit light based on fire information from a fire detector, but all of these devices are expensive and There was a problem in that equipment costs increased significantly.

The present invention was developed in view of the above problems, and provides an inexpensive fire display device with a simple structure that quickly and accurately displays the location of a fire based on fire information from a fire detector. The purpose is to

To achieve this objective, the present invention has developed a fire display device that displays fire occurrence areas such as floors and fire occurrence areas where floors are divided into multiple areas based on fire information from fire detectors. A display board equipped with a district indicator light that lights up to indicate each district in the warning area and a movable district display board that overlaps the display board are installed in each warning area, and each district display board for each warning area is Display parts with letters displayed in positions corresponding to the district indicator lights are arranged, and the district display board corresponding to the fire outbreak area is superimposed on the display board,

18 is a display floor discrimination circuit;
Detection signals from switches 3b, 3c, 3d, and 3e that continuously operate in order corresponding to switches 3, 4, and 5 are input, and the switches 3b, 3c, and 3 in the final order
In response to the detection signals from d and 3e, each floor 2,
3, 4, 5 and each switch 3b, 3c, 3
If the detection signals from d and 3e are not input, it is determined that the floor is 1, and the floor displayed on the fire display section 2 is determined. The control unit 19 incorporates a microcomputer, receives fire information from the receiving circuit 13, and sends a drive signal to the alarm drive circuit 20.
The alarm 21 is sounded to warn of the occurrence of a fire. Further, the floor indicator light drive circuit 16 is operated based on the fire information from the receiving circuit 13, and a discrimination signal from the display floor discrimination circuit 18 is inputted, and the district indicator light drive circuit 17 is operated, and the discrimination signal is inputted. Turn on the district indicator light on the corresponding floor.
Further, based on the operation of the test section 15, a test signal is sent to the test circuit 14 installed in the caution area of the floor corresponding to the discrimination signal from the display floor discrimination circuit 18.

Next, the operation will be explained with reference to the flowchart shown in FIG.

Each of the fire detectors 12 installed in each warning area that divides each floor of a building etc. is constantly monitoring fires, and the control unit 19 monitors the fire signal from the receiving circuit 13 in block a. .

For example, when the fire detector 12 installed in district A on floor 1 detects a fire and sends out a fire signal, the corresponding receiving circuit 13 receives the fire signal, and sends out a fire signal along with an address number coded for floor 1 and district A. The information is sent to the control section 19. When fire information is input in block b, the control section 19 stores the input fire information. Block c decodes the address number from the input fire information and identifies that the fire detector installed in area A on floor 1 has triggered an alarm. In block d, the floor indicator light drive circuit 16 is operated to light up the floor indicator lamp 1a corresponding to the floor 1. In block e, a drive signal is sent to the alarm sounding circuit 20 to operate the alarm 21, and the sound of the alarm 21 is used to warn of the occurrence of a fire. When disaster prevention personnel recognize that a fire has occurred from the sound of the alarm 21, they turn on the floor indicator light 1.
The user confirms that the fire has occurred on floor 1 by lighting a, and operates the fire display section 2 corresponding to floor 1. In other words, the current district display board 2b (floor 2)
is displayed, the district display board 2b is rotated and opened using the push plate 10b or the like to reveal the display board 2a. In this state, each switch 3b, 3
Since blocks c, 3d, and 3e are not operating, it is determined that the displayed floor corresponds to floor 1 in block f. Proceeding to block g, a drive signal is sent to the district indicator lamp drive circuit 17 to turn on the district indicator lamp 6a corresponding to district A, and the name of the district where the fire occurred is determined on the display section 9a. Block h judges whether the recovery switch 4 has been operated or not, and if there is no recovery operation, it returns to block a and monitors the fire information, and if there is a recovery operation, it moves to block i and switches on the district indicator light 6a and the floor indicator light. 1a is turned off and the alarm display is restored.

Next, the test operation will be explained.

In block j, test switches 8a, 8b, 8
It is determined whether or not the test switches c, . Here, for example, floor 5
To conduct an alarm test for the fire detector 12 installed in district A, the district display board 2e corresponding to the test floor 5 is rotated and exposed, and the switch 3e is activated by the push plate 10e to open the fire display section. 2 to the floor display corresponding to test floor 5. Next, the test section 15 is operated to turn on the test switch 8a corresponding to district A. Switch 3 in Block K
When e and test switch 8a are turned on, it is detected that the signal is a test signal for the fire detector installed in area A of test floor 5. In block l,
Specify the address number of the test circuit corresponding to the fire detector to be tested based on the test information detected in block k, and test the fire detector 12 by operating the test circuit 14 corresponding to the address number specified in block m. Report it.

When the fire detector 12 sends out a fire signal due to a test alarm, the floor indicator light 1 corresponding to the floor 5 is activated in the same manner as when a fire signal due to a fire alarm is received.
e lights up and the alarm 21 sounds. The person in charge of disaster prevention confirms that the test alarm is on floor 5 by turning on the floor indicator light 1e, and operates the fire display unit 2 to display the district display board 2e corresponding to floor 5. District indicator light 6a corresponding to A
lights up, confirming that a fire signal from the test alarm from the fire detector installed in area A on floor 5 has been received.

In the embodiment shown in FIG. 1, the district display boards 2b, 2c, 2d, and 2e corresponding to the floor where the fire occurred were manually rotated and moved so as to overlap the display board 2a. The district display boards 2b, 2c, 2d, and 2e may be automatically rotated and moved by rotating a predetermined number of times based on fire information from a fire detector.

In addition, as a detection element to detect the display floor,
When the district display boards 2b, 2c, 2d, 2e are rotated, the corresponding push boards 10b, 10c, 10d,
Switches 3b, 3 operated by pressing 10e
The push plates 10b, 10c, and 10c corresponding to each floor are constructed using optical detection elements containing a pair of light-emitting elements and light-receiving elements.
The display floor may be detected by making the reflected light from 10d and 10e enter the light receiving element.

Further, instead of the test switches 8a, 8b, ...8h, a control switch for controlling a smoke prevention device, for example, is provided, and the control unit 19 is activated based on the operation of the control switch.
If the structure is configured such that a command signal is sent from the system to drive and control the smoke prevention equipment installed in the corresponding area, it is possible to promptly extinguish the fire by operating the corresponding control switch upon receiving fire information.

As explained above, according to the present invention, the district display board corresponding to the fire outbreak area is rotated and moved and superimposed on the display board, and the district indicator light corresponding to the fire outbreak area is turned on to indicate the fire outbreak area in letters. By displaying this, it is possible to quickly and accurately display the name of a fire outbreak district from among a large number of warning districts.

Furthermore, by displaying the district name in text for each warning area such as floor, it is possible to easily visually check the spread of the fire.
