Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a 5K escape/guidance light device that changes the display mode depending on the detection operation of a fire detector.

BACKGROUND ART Conventionally, evacuation guide lights have been proposed that enhance the guidance effect by adding a sound display using a speaker or the like or adding a flashing light such as a xenon lamp in the event of a fire. It is conceivable to use a relay that responds to the detection operation of fire detection to display an indication in the event of a fire in such an evacuation light, but this requires special wiring for relay control. It is.

It is also conceivable to superimpose a high frequency signal on the signal line for control, but this also requires a special signal. Therefore, these methods increase the cost as a whole, and are extremely difficult to apply to existing systems.

The present invention was made to solve the above-mentioned conventional drawbacks, and does not require any special wiring.

Therefore, it is an object of the present invention to provide an evacuation guide light device that is inexpensive and can be applied to existing equipment without changing the wiring.

Another object of the present invention is to provide an AS guide light device that can reliably change the display mode of a free guide light device in the event of a fire for the detection operation of a fire detector even when the power supply is interrupted. It is something.

The present invention transmits a signal to change the display mode in the event of a fire according to the detection operation of a fire detector, superimposed on the power supply asynchronously with the power frequency, and transmits power to a transmitting device that sends the signal in the event of a power outage. The device is characterized in that it is equipped with a battery that supplies power to compensate for the operation of the transmitting device even in the event of a power outage, and further ensures that signals can be transmitted and received regardless of the presence or absence of power supply voltage. Lecture 1 figure below
The basic configuration of the present invention will be explained with reference to FIG. (1)
is a free guide light, and an arbitrary number of power sources * (2) are provided. For example, as shown in Fig. 2, this sII guide light (1) is connected to the well-known sign board (3) and this 41 sign board (3).
A display device (4) that is always activated and consists of a lighting device (not shown) that illuminates the camera from behind, and a second display device that is activated in an emergency when it receives a signal from a transmitter (9) that will be described later. (5).

(6) To have - [to be. The second display devices (5) and (6) are, for example, those that generate sound using speakers and those that generate high-intensity flashing light using xenon lamps. However, either one is fine (
Alternatively, it may be one that performs other functions, which can be determined depending on the installation location and the like. These operating devices are powered by a separate battery or have one-check switches f7) and (8).

It also includes devices similar to those conventionally known. The transmitting device (9) is a transmitting device αυ activated by the detection operation of the fire detector α1, for example, in response to an automatic fire alarm. The activation signal is sent to the Joki Kamegen Line 2) asynchronously with the power frequency.In other words,
For example, an address signal (5) and a second display device (5) as shown in Figure #13.

(6) is used to send out a control signal (B) for activating. The A address signal (4) is used to select which area of the evacuation JIIiIl guide light (1) is to be controlled depending on the location of the fire. In addition, the transmitting device (9) may be configured to receive a return signal from a receiving device 03, which will be described later, or a second display device + after extinguishing the fire.
5) and (6) may be sent out.9 (13 is a battery).

During a power outage, power is supplied to the transmitting device (9) and the transmitting device (
9). This patch! JQ
Although 2+ is shown as built in the transmitting device (9) in Fig. M1, it is optional whether it is provided separately from the fs transmitting device (9).

The receiving device 1t (13) is provided corresponding to the free guide light (1), and receives the signal from the transmitting device (9) and identifies the control signal corresponding to its own address (42).
It controls the display device 1 (5L (6)) of the shelter light (1).Here, "corresponding to the evacuation guide light (1)" refers to a one-to-one correspondence, a plurality of grouped play guide lights, etc. Light (1)
This means that one receiving device 0 can be any of the corresponding ones. Soshi- [, transparent guide light tl)
It is also optional whether or not it is built in.

Next, we will discuss the effect. Now, if #t# is normal and a certain fire detection 3 (11) detects a fire, the transmitting device aυ is activated by this verification mark operation.

Therefore, the transmitter J & +9) sends a signal to change the display mode of the evacuation S/S guide light (1) corresponding to one location where a fire has occurred. Receiving device u3 receives this signal and classifies it.

As a result, the selected m-steep guide light (1) operates the second display device 1 (511 (6)), thereby further enhancing the crushing effect and contributing to quick evacuation.

Next, when the fire detector (11) detects a fire during a power outage of the d source, the transmitting device (9) similarly transmits a signal of 1 m because it is supplied with power from the battery A2.
# line (2) K has no power supply voltage, but it is of course connected to the transmitter (
Since signal 9) is transmitted asynchronously with the power supply frequency, transmission is possible regardless of a power outage, and reception is also possible at the receiving device αJ regardless of a power outage. Therefore, the desired #I2 display devices (5) and (6) can be operated in the same way as when the power supply is normal.

On the other hand, those that synchronize with the power frequency are 11C#
It is clear that without voltage, transmission and reception are impossible.

Next, avoid+lI! An example of a specific circuit configuration of the guide light is shown in FIG. The same reference numerals as in Figures 81 and 42 mean the same thing. First of all, it is stable and well-known as a Jl trout guide light! (100), Kanai Hikari 2 (101), Charging (

A relay excitation coil (202) is provided between the output terminals of the charging circuit (201) via a contact of a transmitting device (υ).In other words, the relay excitation coil (202) is excited by the transmitter *maυ The contact point (of this excitation coil (202))
203) is provided to switch the input of the 7 lip 70 knob (204), and the clip 70 knob (204)
By switching the input, data is given to activate or deactivate the 82 display devices of the escape light. The reset output of the clip 70 tube (204) is directly input to the encoder (205), and the NAND
It is input to one input terminal of the AND circuit 6). This N
The other input terminal of the kND circuit (206) has a time constant circuit (
207) is input. And NANDAN
The output terminal of the D circuit 6) is connected to the clear terminal of the counter (208) and one input terminal of the AND circuit (209). The clock output of the counter (208) and the output of the astable multi-pipe V-tar (210) are input to the other input terminal of the ANL) circuit (209). Also, the output terminal of the ANi) circuit (209) is the set input terminal of another Noritsu flop (211).

The seven terminals of the color/receiver (208) are respectively connected to the reset input terminals of the same seven lip flops (211). The set output of this flip frog (211) and the astable multivibrator (210)
The output is input to the encoder (205) via an AND circuit (212).

The output of this AND circuit (212) causes the encoder (205) to be connected to the encoder (205).
HD-9 can be used. The encoder (20
5) further includes an address setter (213) and a clock generator (214).

The output of the mtii2 encoder (205) is further sent to the power line (2) via the coupling transformer (216) on the condition that it is ANDed with the output of the astable multivibrator (215).

Next, we will discuss the operation of the relay contact (20
3) is connected to the reset input side of the 7 rig 707 (204).
The reset output of 204) becomes 1, and by designing the rise of the output of the specific a-path (207) to be later than the cycle of the astable multivibrator (210), NAND
The output of the AND circuit 6) is initially 1 and becomes 0 depending on the time constant. Therefore, first, the output of the AND circuit (209) is 1 and the 7 resog 70 knob (211) is set, and then.

The counter (208) starts counting when O is input to the clear terminal.

Since the flip-flop (211) outputs 1 until the count of the counter (-208) reaches a predetermined value, the encoder (205) has an astable multi-noise Z ia' v -p(
210) is input, and the encoder encodes and outputs the input data (second display device is inactive) using the input address of the flip-flop (204).

and a modulated signal 6t.

It is sent to the source m(2) via the coupling transformer (216). Then, when the count of the counter (208) reaches a predetermined number, reset manual power is supplied to the flip 70 knob (211), so that the encoder (205) is de-energized and therefore stops outputting.

Next, when the 9 transmitter 03 is activated, the relay contact (
203) is switched and therefore the flip-flop (
The output of 204) becomes 0 and is inputted to the encoder (205) and inputted to one input terminal of the NAND AND circuit 6). At this time, the output of the second time constant circuit (207) is standing, so the counter (207)
08) is inputted with 1 to the clear terminal and stops counting.

On the other hand, 1 is input to the AND circuit (209) and sets the flip 70 knob (211), so the encoder (205) outputs a signal as described above.0 In this case,
Since the counter (208) will not be cleared unless the output of the flip-flop (204) is inverted, Norinob 7
There is no need to reset the 0 knob (211).

That is, the encoder (205) continues to output signals. Note that we have omitted the correspondence between the fire detection scod and the evacuation guide light (1), but for example, if the transmitter 0 row is set up in correspondence with the fire detection 4a groan, depending on which launching device 0 moat is activated, Address setter (2) in Figure 5
It is easy to understand that this can be achieved by controlling 13).

In the receiving device, power for each device is obtained from both ends of the battery, ie, the outlet of the charging circuit, via a stabilizing circuit (300), as shown in the fourth figure. A coupling transformer (301) is provided on the power line (2) to receive the transmitted signal, and an amplifier (302) and a detection a (ao3)* comparator
It is input to the decoder (305) via (304). This decoder (305) has an address setter (306).
