Description

DETAILED DESCRIPTION OF THE INVENTION 4-The invention relates to an evacuation guidance device for guiding people to emergency exits in a safe direction in the event of an emergency such as a fire in a building, underground mall, etc.

Generally, buildings, underground malls, etc. are equipped with fire alarms.
If an emergency situation such as a fire occurs, this fire alarm will activate and ring a bell to notify people in buildings, underground malls, etc. of the emergency situation and to evacuate to emergency exits. Fire scenes were often filled with smoke or due to power outages, people's eyesight became impaired, making it difficult to locate safe emergency exits.

The present invention has been made in view of two consecutive circumstances. Loudspeakers are installed along evacuation routes in buildings, underground shopping malls, etc., and the output of these loudspeakers not only alerts people to emergencies such as fire, but also prevents smoke and power outages. The purpose is to provide an evacuation guidance device that guides people to emergency exits in a safe direction regardless of obstacles such as

The present invention is a guidance device that guides people in a safe direction in the event of an emergency such as a fire in a building, underground mall, etc., and the guidance device includes a plurality of guide devices arranged at required intervals along an evacuation route in the building, underground mall, etc. An emergency evacuation system comprising: a loudspeaker; and a control device that broadcasts an emergency broadcast all at once to the loudspeaker and sequentially switches and outputs a tone indicating an evacuation direction along the evacuation direction. This relates to a guidance device.

Hereinafter, the present invention will be described as follows: Example 711 shown in FIGS. To explain based on example i, FIG. 1 is a block diagram showing one embodiment of the evacuation guidance system according to the present invention, in which 1.1' is a fire detector, 2
is the fire alarm, 3 is the control circuit, 4 is the loudspeaker SPI ~
An announcement device is used to set the contents to be broadcast from the SP 5 and to indicate the end of the broadcast when the broadcast ends, 5 is an audible frequency oscillator, and 6.7 is an amplifier.

In addition, E is a capacitor, R1-R4 are fixed resistors J2 or variable resistors, D1-D6 are diodes 1', 01-06 are capacitors, SPI-SP5 are loudspeakers, XI-X9 are relays, Xl - Xl It is a contact corresponding to the above Xl - Xl, X tO is a contact that closes when either fire detector 1 or 1' detects a fire, Xll is a contact corresponding to fire detector 1
Xn is a contact that closes when the fire detector 1' detects a fire.

In the configuration described above, first, the contacts X 10 to XI2, which are provided in the fire alarm 2, will be explained.
1 is a contact that closes when either fire detector 1 or I:t I' detects a fire, and Xu, X
+241 are contacts corresponding to fire detectors I and 1' respectively, X11 is a contact that closes when fire detector 1 detects a fire, and xn is a contact that closes when fire detector 1' detects a fire. Not used in this case.

Next, to explain the operation when the fire detector 1 detects a fire, the contact X 10 provided in the fire alarm 2 will be described.

The audible frequency signal is sequentially switched over to the amplified tone by the amplifier (i. Then, when the tone from SR5 ends, it is set in the announcement device in advance), :, the release of the fire alarm 11, and 1- The loudspeakers 5I) 1 to SR5 mentioned above

When X2b operates, the capacitor C1 connected in series to ζ,

Discharge to 3. Then, a current flows through relay X3 and operates as x3α, but the voltage of capacitor CI is equal to
Contact x3α continues to operate at 1゛, which decreases exponentially depending on the resistance value of column 1 of relay Charge C2 to the voltage of capacitor E. Next, when the current of relay x3 reaches the touching current, contact x3
1L moves back to its original position, and the capacitor C2 charged to the voltage of the capacitor E mentioned above is discharged to the resistor R2 and variable resistor R3 via the relay X4 and diode D2, and the contact X4a is discharged. works. This operation is carried out by relay X5. X6 and Xl are repeated in this order, and at the same time contacts X3b-X7b of relays The output is amplified by the amplifier 6, and the output is sent to SPI, Sr2. In addition to Sr3°SP/I and SR5 in this order, the =I intensity C1

The resistor R2 and the variable resistor R3 are set in advance and switched at one-hour intervals, and by transmitting audible frequency tones through a loudspeaker, it is possible for a person to know 1 or 11 directions. You can do it.

These loudspeakers then output a dial tone, SI) 5

L moves to its original position, contacts X2b closes, and -1 announces the preset fire/L broadcast on the announcement device mentioned above and the instruction to move in the direction of movement of the tone output from the loudspeaker. Broadcast simultaneously through devices SPI to SP5.

When this broadcast ends, the amplifier 7 amplifies the signal for turning off the current flowing through the relay

g (1 operates on the relay X2 side and X9G operates on the oscillator 5 side. Then, due to this operation, current flows to the relay
are switched in order, and the loudspeakers operate to output the beeps in order from 11 and SP1 to SP5, and each loudspeaker is operated to output the beeps in order from SP1 to SP5, and each loudspeaker is used to change the beeps IjIJ, to emit fire when a fire occurs, and to shift the beeps!8+ It operates by repeatedly broadcasting instructions to the direction of the direction.

Next, to explain the behavior 4'1 when the fire detector 1' detects a fire, the contact X In

That is, when the fire detector 1' detects a fire, the direction of movement of the tone output from the loudspeaker is made to be opposite to that when the fire detector 1 detects the fire.

The ``11 guidance seat'' configured in this way is the second
As shown in Fig. 1, if the fire detector 1 detects a disaster, people can be lured in the direction of the arrow in Fig. 2, and if the fire detector 1' detects a fire. is I, which can guide people in the opposite direction.

In the example, the number of loudspeakers is 511AI, but it is possible to increase the number of loudspeakers to expand the scale of the guidance device, or to use this guidance device in k number of times to increase the scale to 1j: thick. Of course, it is good to do 1).
