JPS60712Y2 - Evacuation guidance system - Google Patents

Description

[Detailed explanation of the invention] In the event of a fire, this invention stops guiding people to the route where evacuation obstacles such as smoke, heat, flames, etc. have occurred among multiple evacuation routes, and leads them to a safe evacuation route. This invention relates to an evacuation guidance system that provides active guidance.

A guide light installed at an evacuation exit of a building indicates the existence of the evacuation exit to people present at the location.

However, in the event of a fire, the guide lights have the disadvantage that they are covered with smoke and cannot be seen, or are mixed with other display decorations and are difficult to stand out.

To solve this problem, a so-called guide light activation mechanism is installed near the guide light or on the guide light itself, so that when a fire occurs, the flashing light and It is well known that both or one of the sounds is emitted to make the people present (people requiring evacuation) clearly aware of the presence of the guide light, that is, the location of the evacuation exit.

However, as mentioned above, although the guide light activation mechanism is effective in increasing the attention (attraction) to the guide light and clearly informing the location of the evacuation exit, This does not guarantee that the outside of the evacuation door, etc., is safe.

It is easy to predict that fire and smoke may be present outside the evacuation door, making it unsuitable for evacuation.

Therefore, the present invention aims to quickly identify routes where evacuation obstacles such as smoke, heat, and flames have occurred among multiple evacuation routes, and stop the operation of the guide light activation mechanism for that route, resulting in a safer evacuation. This provides an evacuation guidance system that provides guidance to a route.

The present invention will be explained in detail below. In addition to placing fire detection sensors at multiple appropriate locations within the building, a guide light activation mechanism that operates automatically or manually based on signals from the fire detection sensors is used to guide multiple evacuation exits. The installation of each device on each lamp is the same as in the past.

In this invention, appropriate sensors such as smoke detectors, heat detectors, fire detectors, etc. are installed in evacuation routes such as evacuation stairs, and when this sensor is activated, the The guide light activation mechanism that is emitting flashing lights and sounds along the route is made to stop its operation (flashing lights and/or sounds).

In the above configuration, when a fire occurs, the guide light activation mechanisms installed in areas requiring evacuation are activated all at once.

Next, if the fire progresses and evacuation obstacles such as smoke, flames, or heat occur on the evacuation route, the sensor will operate and the guide light activation mechanism for the evacuation route will stop operating, causing evacuation. Avoid actively inducing others.

When there are three or more evacuation routes, as obstacles occur in each evacuation route, active guidance to that evacuation route will be stopped one by one, and guidance will be directed to an evacuation route with no obstacles. .

Furthermore, if the fire progresses further and there are obstacles to all evacuation routes, evacuees will have no choice but to somehow break through the obstacles and evacuate. All guidance light activation mechanisms that had been installed will be restored, and flashing lights and sounds will be emitted simultaneously to make evacuees aware of the existence of the evacuation route.

To explain the above operation using a specific example, in the figure,
The building has four evacuation stairs A, B, C, and D, each equipped with a guide light activation mechanism 1at 1b*
IC, 1d and evacuation obstacle detection sensor 2a = 2
bs 2c and 2d are installed.

The operating steps in the event of a fire are as follows.

■↓■↓ fire outbreak Guide light activation mechanism 1a, lb, lc.

1d works all at once.

To evacuation stairs A Problems such as smoke Living Guidance light activation mechanism 1a stops operating and induced by other lb, lc, and ld.

■ Evacuation stairs A and guide light activation mechanisms 1a and lb stop operating and block B and are guided by other lc and ld.

Occurrence ■ Evacuation stairs A, guide light activation mechanism 1a, lb, lc
↓ Stops the operation at B and C and guides only by 1d.

Failure Occurrence■ All evacuation stairs A, guide light activation mechanism 1a, lb, lc
.

1d again moves in unison to B, C, and D.

Occurrence of Failure As explained above, according to the present invention, among the plurality of evacuation routes, the guidance light activation mechanism immediately stops its operation on the evacuation route where the failure has occurred to prevent active guidance. As long as the guide light activation mechanism is in operation, it will indicate a safe evacuation route according to the situation at the scene.
This provides an innovative and highly effective evacuation guidance system that allows people to safely follow the guidance and evacuate quickly.
