Description

[Detailed description of the invention] 〔Technical field〕 The present invention relates to an evacuation guidance device.

[Background technology]

Guide lights are a device that allows people to safely evacuate in the event of a fire in a building, which indicates the location of emergency exits and emergency stairs. Some guide lights are normally turned off, but are turned on in an emergency. There are also systems that receive the operation of a fire detector and display a preset evacuation direction by lighting an arrow, but none of these methods takes into account the location of the fire and the area where the fire has spread. Depending on the location, evacuation routes may be blocked by smoke from the fire, even if you follow the direction of the arrow to evacuate.Therefore, evacuation guidance that is more in line with the actual situation of a fire outbreak is desired.

[Purpose of the invention]

The present invention has been made focusing on the above-mentioned problems,
The purpose of the present invention is to obtain an evacuation guidance device that indicates the safety of the evacuation direction using color-coded guidance lights with good visibility in accordance with the reception status of a fire receiver.

[Disclosure of the invention]

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

Control BHf power line 1h-1 that receives a fire signal and turns on the guide light S! Terminals A*"*B2 to Bn are provided in parallel to each other to which contacts that close in response to a fire signal can be connected. Terminal A is, for example, the fire representative IJL of the receiver.
/- contacts are connected, and terminals Bl-Bn are connected to the fire area U.
The L/- contacts are connected. A relay RA is connected between the terminal A and the power line l1. Terminals B1-B
n is output by the logical product of the fire area contact points) I
Connected to Jx circuit M. This matrix circuit M may be a matrix circuit using diodes. A relay RB is connected between this matrix circuit M and the power line 11,
RC is connected. Relays RB and RC are configured such that relay RB is energized by a certain combination of closed circuits of the district contacts, and relay RC is energized by another combination, and relay RB is connected to guide light S that lights up. The matrix is configured such that the relay RC is activated when the evacuation direction is a dangerous evacuation direction considering the fire occurrence location at the installation location, and the 2 relay RC is activated when the M direction is dangerous. . Relay RC is energized when a fire occurs in at least one location. These Ranori V-RA, RB, and RC are provided as contacts rae rb * r (!) on the control line that also serves as the power supply to the guide light S, and the contact ra is a normally open contact, and the contact rb r r c is It is used as a switching contact.The guide light S is colored blue to indicate safety, caution, and danger in the evacuation direction with good visibility, so the color is blue for safety, yellow for caution, and red for danger.As mentioned above. To further explain the contact points ra*rb and re of the control line, the contact point r
When a fire is received, circuit a is closed so that the guide light S can be energized. In this state, the contact rb*rc reaches the blue indicator light side S1, so only the blue indicator light Sl lights up. Therefore, if the contact rb is switched, the yellow indicator light is lit, and if the contact rc is also switched, the red indicator light is lit.

Next, the operation will be explained. First, when a fire is detected in a place where there is agitated materials, relay RA is energized and contact ra is closed. If the fire detection point is located at the installation position of the guide light S and the evacuation direction is safe, the blue indicator light Sl lights up. If caution is required at this point, the contact rb is switched and the lighting of the blue indicator light S1 is switched to the lighting of the yellow indicator light S2. If the evacuation direction is still dangerous at that point or after that, contact re
is switched and the red indicator light S3 lights up.

Any number of guide lights S may be provided, in which case relays corresponding to relays RB and Re may be provided and M) I
It is sufficient to increase the number of AND circuits inside the Jx circuit M.

〔Effect of the invention〕

As described above, according to the present invention, the configuration is configured to display the safety, caution, danger, etc. in the evacuation direction by lighting the easily visible color-coded guide lights based on the AND output of the detection signals for each fire warning area. Therefore, compared to the conventional display of the evacuation direction that does not take into account the location of the fire outbreak and the area where the fire has spread, the present invention clearly displays whether the evacuation direction is safe, requires caution, or dangerous based on the logical product of fire reception by color-coding. This made the evacuation safer. In addition, since it is color-coded to match the traffic lights, if it is installed at a school or other facility where children go in and out, even children will be able to make the correct decisions and evacuate.
