3, the transmission of the evacuation signal output from the repeater T3 is stopped at the repeater T2.

In addition, 15 questions of
Each evacuation signal processing between I4 and T15 is also performed by the above repeater T2.
．． This is done in the same way as during T3, and evacuation signals in opposite directions flow through the pair of signal lines 1 between the respective repeaters.

The guide lights connected to each signal line 1, under the control of the evacuation signal flowing through each signal line 1, instruct the evacuation direction as shown by the solid arrow in FIG. 1, which is opposite to the transmission direction of the evacuation signal.

Subsequently, when the fire door provided on the stairs 22 is closed to prevent fire and smoke from spreading to other floors, a closing signal is input from the fire door to the signal transmitter G2.

Upon input of the closure signal, the signal transmitter G2 stops transmitting the evacuation signal, and the repeater 'r8t T12 jT'ts l

Although a signal branching circuit having four pairs of input/output terminals is used in the above embodiment, the number of pairs is not limited to four, and a signal branching circuit having arbitrary pairs of input/output terminals corresponding to the branching direction of the branching point can be used. can be used.

In addition, if an evacuation exit is provided in the middle of corridor 1, it is sufficient to install a signal transmitter at the evacuation exit and send an evacuation signal from the signal transmitter to a pair of signal wires. If a fire door is installed, a signal breaker can be installed in the fire door to block transmission of evacuation signals when the fire door is closed, thereby indicating the direction of evacuation with the closed fire door. can.

Furthermore, if there are variations in the operating time of the emergency door or fire door opening/closing device, a change in evacuation direction due to the variation in the operating time can be prevented by providing a delay circuit or a synchronization circuit in the signal transmitter.

Furthermore, if you want to give priority to safe passages depending on the condition of the evacuation route, for example, you may want to make the repeaters installed in narrow evacuation passages with low priority closer than those in wide evacuation passages with high priority. Alternatively, by using a repeater equipped with a delay circuit to delay the signal transmission time from the signal transmission time of a wide evacuation route, it is possible to instruct an evacuation direction that prioritizes the wide evacuation route.

Further, although the repeaters T1 to T16 are constructed of signal transmission circuits, a signal transmission circuit or a signal cutoff circuit may also be incorporated therein.

An embodiment of the repeater will be explained with reference to FIG.

FIG. 8 shows an embodiment of a signal transmission circuit T in which the signal line is shared with the power supply line, the input terminal 1a is connected to the signal detection relay Y1 via the break contact y21 of the relay Y2, and the input terminal 2a is Break contact y1□ of relay Y1 above
is connected to signal detection relay Y2 via
The other ends of Y1 and Y2 are grounded.

Further, the input terminals 1a and 2a are connected to backflow blocking diodes d1 and d2, and the diodes d1 and d2 are grounded via a slow-acting relay K to ensure that the evacuation signal is transmitted sequentially. Connected to the make contact k of the relay.

This contact is connected to the output terminal 1b via the meter contact y2□ of the relay Y2 and to the output terminal 2b via the make contact y12 of the relay Y1.

In the signal transmission circuit T, when an evacuation signal is input to the input terminal 1a, the relay Y1 is operated, and the operation of the relay Y1 opens the contact y1□, prohibiting the evacuation signal from being input to the relay Y2, and the contact y12 is opened. Closed.

Then, the input evacuation signal causes the slow acting relay K to operate and close the contact k.

By closing the contact, the evacuation signal input to the input terminal 1a is outputted from the output terminal 2b via the contact y12.

Therefore, if the signal transmission circuit T is used, the evacuation signal can also be used as the operating power source for the circuit T, so the signal line and the power line can be shared.

FIG. 9 shows an embodiment of a signal transmission circuit T equipped with a circuit for preventing oscillation of the evacuation signal, and input terminals 1a and 28 are connected to signal transmission AND circuits A1 and A2, respectively.

Connected to 2.

The output of the AND circuit A2 is connected to the output terminal 1b paired with the input terminal 1a, and is also connected to the transfer control NOT circuit N.
2 to the AND circuit A1.

When the evacuation signal is not input to the input terminals 1a and 2a of the signal transmission circuit T, only the NOT circuits N1 and N2 produce outputs, and the AND circuits A1 and A2 do not operate.

When evacuation signals are simultaneously input to the input terminals 1a and 2a, the AND circuits A1 and A2 both operate to produce an output.

The outputs of the NOT circuits N1 and N2 become zero due to the respective outputs of the AND circuits A1 and A2, and the operation of the AND circuits A1 and A2 is prohibited due to the zero outputs of the NOT circuits N1 and N2.

When the output of the AND circuit A1 becomes zero, the monostable multivibrator M operates and produces an output for a certain period of time.

The above NOT circuit N is activated by the output of the multivibrator M.
1 continues the zero output and continues to prohibit the operation of the AND circuit A2.

The NOT circuit N2 generates raw power due to the zero output of the AND circuit A2, and the output of the NOT circuit N2 causes the input terminal 1 to
The AND circuit A, to which the evacuation signal is input from a, operates and produces an output.

The output of the AND circuit A1 is output from the output terminal 2b and is also input to the NOT circuit N1, and the NOT circuit N1 continues to output zero even if the output of the multivibrator M becomes zero after a certain period of time.

As a result, the transmission of the evacuation signal input to the input terminal 2a is stopped by the AND circuit A2, and the evacuation signal output from the output terminal 2b can be prevented from oscillating.

The signal transmission circuit was designed to give priority to the evacuation signal input to the input terminal 1a, but when no signal is input to the monostable multivibrator M, it produces an output, and when a signal is input, the output remains unchanged for a certain period of time. By changing to a monostable multivibrator with a zero value and changing the OR circuit R to an AND circuit, priority can be given to the evacuation signal input to the input terminal 2a.
