Description

[Detailed Description of the Invention] The present invention is an example of an M-leaving guide light. Concerning the Choichi lantern device that changed the number 1 to 5.

In the event of a fire, in case of a fire, in addition to the normal guidance display, guidance is provided by Ci, or by using high-intensity flashing lights to achieve the same guidance effect as above.
Guide lights were proposed.

Possible ways to change the display mode in this way include using a relay or connecting the signal line to tr/
A control signal is sent to the signal line of the Jilt L lever. However, all of these are small in that they require special distribution. Sometimes it is extremely difficult to add additional wiring to equipment that has already been wired.

On the other hand, it is extremely advantageous to perform so-called power line transport in which the control signal is modulated and sent to the power line, as no special wiring is required.

The present invention has been made in consideration of such circumstances, and operates and stops the display device that should be activated in an emergency of the evacuated IAn guide light by sending a control signal to the power supply line.
Furthermore, the 2 activation signal is sent repeatedly within the period for activating the emergency display device, the stop signal is repeated only a predetermined number of times, and an 1IIn light guide device is provided that can reduce the problem of l#i frequency noise as much as possible. The purpose is to

The schematic structure of the present invention will now be described with reference to FIGS. s1 to 3. (1) is an evacuation guide light, and an arbitrary number of evacuation guide lights are provided on the power line 2). An example of the structure of this evacuation guide light (1) is shown in FIG. 2. In other words, the well-known signboard (3) and the light from a lamp such as a lamp shining from behind this signboard (3)
(4). These signboards (3) and light +1
i(4) is the first display device (5) that provides constant guidance display.
).

Furthermore, the evacuation guide light +1) has second display devices (6), (7) that are activated in an emergency. These second indications are what is emitted. However, the second display device may be only one of them, or may have other functions. It is possible to set it to an arbitrary value depending on the installation location, etc. In any case, a well-known configuration can be used. And the evacuation guide light (1) is
It is equipped with various other devices that conventionally known guide lights have.

(8) is a transmitting device that sends a signal to the power line (2) to activate or stop the second display device (6), (7) of the evacuation guide light (1); The activation signal is repeatedly sent out while the second display devices 16) and (7) are being activated, and the stop signal is sent out repeatedly a predetermined number of times. This transmitting device (8) transmits the activation signal and stop signal in response to, for example, a fire detector (9).

In FIG. 1, when a fire detector (9) detects a fire, a fire alarm 01 is activated, and the activation of this fire alarm OI causes a transmitter (8) to send out a necessary signal. FIG. 3 shows the state of signal transmission by such a transmitter (8). Figure 3 - Figure (a) shows a fire detector (
9) shows the signal of the fire alarm a which is activated by the detection operation, and FIG. 9(b) shows the signal from the transmitter (8).

As is clear from Figure 3, the activation of the fire alarm αl causes the i! ! The second display device (6) of the female lead light (1), (
7), the activation signal is repeatedly sent out while it is necessary to activate the fire alarm α・, and the second display device +6+ is activated.
tf7), a stop signal is repeatedly sent twice. Note that the stop signal may be issued only once instead of twice. Further, in addition to responding to the fire detector (9), the transmitting device (8) may also be configured to send out a signal using a manual switch.

Also, the 2 activation signal responds to the fire detector (9).

The stop signal may be responsive to a manual switch.

Next, aυ is a receiving device, which is provided corresponding to the four evacuation guide lights (1), receives the signal from the transmitting device (8), and displays a second display device in the evacuation guide light (1). (6
), (7). Here, it corresponds to the 111III guide light (1).

This means that either a one-to-one correspondence or a one-to-one correspondence to a plurality of grouped evacuation guide lights (1) may be used. Furthermore, each received value fluυ has its own address, and a control signal that matches its own address is identified and displayed in the second display.

ftt6) and (7). Whether or not this received value atIυ is built into the *a guide light (1) is arbitrary.

Next, we will discuss the effect. When the fire detector (9) detects a fire, it causes a fire alarm 41! IQI works.

The transmitter (8) is activated by the fire alarm tlG.

An activation signal is repeatedly sent to activate the second display device (6), (7) of the evacuation fI11#Ij guide light (1) corresponding to the location where the fire occurred. The receiving device αυ receives this activation signal and activates the second display device (6), (7). In this case, even if the first few of the 9 actuation signals are not transmitted to the receiving device αυ due to some reason such as the mixing of noise signals, the 2 actuation signals are repeatedly sent out.
Unless there is a malfunction in the device, the signal is transmitted to the receiving device αυ, and the second display devices (6) and (7) can be reliably operated. Therefore, it is possible to enhance the induction effect in an emergency and contribute to rapid and reliable release.

Then, when the fire alarm is reset due to extinguishing a fire, etc., the transmitting device (8) changes to the second display device (6).

The stop signal (7) is sent, for example, twice. Receiving device O
υ receives this stop signal and displays the second display device (6L (
7) will be stopped. in this case.

Since the stop signal is repeated only twice, the receiving device αυ cannot receive it for some reason.

Although the second display device 1 (6), (7) continues to operate,
There is no problem from a safety point of view. On the contrary, if a stop signal is continuously sent out, high frequency noise will be applied to other electrical equipment, and problems caused by this high frequency noise will become more serious.

Next, an example of a specific circuit configuration of the mla guide light is shown in FIG. The same reference numerals as in FIG. 1 and FIG. 2 mean the same thing. First, we will start with the ballast (100), Kanai-Kyu lamp (101), and charging circuit (100), which are conventionally known as evacuation guide lights.
02), batch 1 bar 103), 'Inverter (10
4), power failure detection relay (105) and inspection switch (
106). And the Kanai-Kyu lamp (101
) is used to illuminate a sign board as shown in the second figure, which is not shown in FIG. a second display device (6);
As (7), the lighting circuit (108) of the xenon lamp (107) and this lamp C107), the speaker (109), and the drive circuit (110) of this speaker (109) are powered by the charging circuit (102), respectively. line(
2) is connected to. Then, the lighting circuit (108
) and the drive circuit (110).A parallel circuit of a contact (111) of the power failure detection relay (105) and a relay contact (112) controlled by the receiving device Oυ is provided in series at the input end of the drive circuit (110). In addition, in the m4 diagram, the xenon lamp (107) and the speaker (109) have a power supply (113) Q for supplying power during a power outage.Of course, even if the battery (103) is shared, good.

#45 shows a specific example of a transmitting device.

The same reference numerals as in FIG. 1 mean the same things. first,
A transformer (200) is installed on the power line (2).The output of this transformer (200) is used to connect the excitation coil (
201) is provided via the contact point of the fire alarm l100. That is, the excitation of the excitation coil (201) of the relay is controlled by the fire alarm 01. A contact (202) of this excitation coil (201) is provided to switch the input of the flip 70 (203).

The reset output of the clip flop (203), which provides data to activate or deactivate the second display device of the evacuation guide light by switching the input of the clip flop (203), is directly connected to the encoder (203).
4) and is also input to the NANDAND circuit 5) Q
This NANIJ circuit (2
The output of the time constant circuit (206) is input to the other input terminal of the circuit (206). The output terminal of the NAND circuit (205) is connected to the clear terminal of the counter (207) and one input terminal of the AND circuit (208). /
The clock output of <207) and the output of the astable multivibrator (209) are input. Also, the output terminal of the AND circuit (208) is connected to another clip-flop (210).
), and the cent terminal of the counter (207) is connected to the reset input terminal of the same clip-flop (21(1)).The set output of this clip-flop (210) and the astable The output of the multivibrator (209) is connected to the AND circuit (211).
) is input to the encoder (204) through
The output of this AND circuit (211) causes the data obtained by the flip 70 tube (203) to be encoded and output from the engraving encoder (204). Such an encoder (204)
UPER'I'HKd's ICED-9 can be used. The encoder (204) is further provided with an address setter (212) and a clock oscillator (213). The output of the encoder (204) is further ANd with the output of the ring-stabilized multi-pipe V-tor (214).
Combine tiger/x (2ts) with D as condition #*t
2) Send out tt6yo5.

Next, I will explain the function. When 1t#t is turned on, contact 7- (
The flip 70 is configured to be connected to the reset input side of the 202-70 rig
The reset output of the Tsug (203) becomes 1, and by setting tO later than the cycle of the astable multivibrator (209) with a rising edge of the 2-time constant circuit (206) (CIft).
, N1) circuit (205) is initially 1 and becomes O according to the time constant. Therefore, first, an AND circuit (2
The output of 08) becomes 1.

Next, the counter (207) receives 0 at its clear terminal and starts counting. The flip-flop (210) outputs l until the count of the counter (207) reaches a predetermined value, so the output of the astable multivibrator (209) is input to the encoder (204), and the encoder receives the input address, The data input from the Noritsu flop (203) (display device 442 is inactive) is encoded and output. The modulated signal is then sent to the source it 12) via the coupling transformer (215).

Next, when the count of the counter (207) reaches a predetermined number, the set output becomes 1 and the flip 70 knob (210) k
Reset. I wanted to! - encoder (204) stops outputting.

Next, when the fire alarm fllllllG is activated, the relay contact (202) is switched, and therefore the output of the 7 ritsunoflop (203) becomes 0 and the encoder (204
) K is input and both K and NAND times M (205) υ are input to one input terminal. At this time, two time constant circuits (20
The output of 6) is rising.

Therefore, the output of the NANDl path (205) is 1, and 1 is input to the clear terminal of the counter (208).

Stop counting.

On the other hand, since 1 is input to the AND circuit (208) and the clip-flop (210) is set, the encoder (204) outputs the signal as described above. In this case, the counter (207) is not cleared unless the output of the 7-lip 70-tub (203) is inverted, and therefore does not output a reset signal to the clip-flop (210).

That is, the encoder (204) continues to repeatedly output the actuation signal. Furthermore, when the fire alarm Q (I) returns, the output of the clip-flop (203) becomes 1 and the output of the NANDAND circuit 5) becomes 0, so the counter (207) starts counting.

When the predetermined number is reached, a reset signal is output to the clip-flop (210). Namely.

The number of times the stop signal is repeated is determined by the number of stitches on the counter (207). Although we have omitted the correspondence between the fire detector (9) and the 11II111 guide light (1), for example, if the fire alarm α is connected to the fire detector (9),
It is easy to understand that this can be achieved by providing the address setting device (212)'l- in FIG. 5 according to which fire alarm alarm is activated.

Figure s6 shows a specific example of the receiving device. In FIG. 6, the same reference numerals as in FIG. 1 mean the same things. In the receiving device as well, a transformer (300) is provided on the power line (2) to obtain power for each device. 11Lfia (
2) is provided with a coupling transformer (301) to receive the transmitted signal, which is then input to a decoder (305) via an amplifier (302), a detector (303), and a comparator (304). This decoder (305) has an address setter (
306), 45 Clock generation fR in the illustrated transmitting device
A clock oscillator (307) similar to the generator (214) is provided. The decoder identifies the control signal (FIG. 3) of the transmitted signal with the address signal that matches its own address, and then sends the control signal for the display device control of J2' via the slip 70 knobs (308) and (309). Relay excitation coil (3
10). As such a decoder, 80PER'rEK's ICEE-5 can be used. Note that the flip 70 knobs (308), (30
9) forms a latch circuit.

The present invention can be modified in various ways other than the above embodiments. For example, the transmitting device is the #! of an evacuation guide light. The number of times the signal is sent can be changed by identifying when the second display device is activated and when it is deactivated, and such a device can be constructed in various ways by those skilled in the art. Similarly, the receiving device can be modified to correspond to the transmitting device.

Also, the structure of the evacuation guide light can be any type of two-circuit configuration, and 9! It is sufficient that the display device has a first display device that operates at all times and a second display device that operates in an emergency.

As described in detail above, the present invention provides four emergency use lights for free guide lights.
Since the control of the display device in step 2 is carried out by superimposing a signal on 'tll[*, no special wiring is required and it can be constructed at low cost, and it can also be applied to equipment where wiring is already installed.
Noh and more.

The signal for activating the second display device is repeatedly sent during the period during which activation is required, and the signal for stopping the second display device is repeatedly sent a predetermined number of times.

The second display device can be operated reliably to contribute to evacuation guidance;
Furthermore, it is possible to provide an evacuation guide light device that can reduce as much as possible high frequency noise that is a hindrance to other electrical equipment.
