2. Description of the Related Art As a conventional light traveling type evacuation guidance device, the present applicant has filed Japanese Patent Application No. 4-228199 (F21S 3/0).
I have applied for 2).

An outline of the conventional light traveling type evacuation guidance system will be described below with reference to FIGS. 8 to 14.

First, the operation will be described with reference to FIG.
When a fire occurs, the automatic fire abandonment equipment receiver 1 operates,
The information is transmitted to the guide light signal device 3 via the transfer device 2. Then, fire information is sent from the guide light signal device 3 to the fire signal control device 5 inside the control device 22. The fire signal control device 5 determines a taxiway suitable for the fire information, and issues a command to the lamp control device 21 to send a control signal in accordance with the determined taxiway. Each of the lamps 23 connected to the lamp control device 21 is controlled to be turned on / off by a control signal from the lamp control device 21. In the figure, 7 is a DC power supply device, 8 is a storage battery, and 9 is a power supply switching device.

As shown in FIG. 9, the inside of the lamp 23 is
A microcomputer 24 that receives a control signal from the lamp control device 21 and performs various processes according to the control signal.
And an address setting circuit 25 for setting an address assigned to each lamp, and an inverter circuit 26 for oscillating / stopping in response to a command from the microcomputer 24.
And a flat fluorescent lamp 16.

FIG. 10 shows a timing chart of control signals sent to the respective lamps 23. In the figure, 27 and 29 are timing commands, and 28 is address data.

In each lamp 23, after receiving the timing command 27 first, the next timing command 29 is received.
Only the lamp with the address that matches the address data 28 received until the next timing command 29
Lights up when is received. Lights that do not match are turned off.

When the control signal is sent at this timing, for example, the installation interval of the lamps is 0.5 m and the traveling speed of light is 2.5 m.
/ Sec, the timing command is 250 mse
If it is transmitted for each c, one of the five lamps can be set to be always on.

FIG. 11 and FIG. 12 show such one lighting 4
It shows the light traveling state and data sent to the lamp when light traveling to the right in the off state. In this example, as can be seen from FIG. 11, only the lamps of addresses 1, 6, 11 are turned on, then only the lamps of addresses 2, 7, 12 are turned on, and only the lamps of addresses 3, 8, 13 are turned on. The light appears to move in the direction of the arrow by controlling the lighting and so on.

As shown in FIG. 11, an address is set for each lamp 23, and data shown in FIG. 12 is sent to all the lamps. T in FIG.
Represents a timing command, and each numeral represents address data. Although data is sent to all the lamps, as described above, only the lamps having the same address are turned on.

[0011]

However, the above-described conventional light traveling type evacuation guidance device has the following drawbacks. (1) Since it is necessary to set all the addresses of each lamp individually, management of lamp installation is complicated. (2) Since a large number of address data are transmitted between timing commands (≈lighting period),
The number of lights installed in the entire lamp is limited by the lighting cycle and the lighting interval of the lamp.

For example, when the lighting cycle is 250 msec,
Since the maximum number of address data that can be transmitted is about 100, as shown in FIG. 11 and FIG.
If the light running pattern is off, the maximum number of all installed lights is 50.
0 lights. Also, as shown in FIGS. 13 and 14, one lighting 3
If the light running pattern is off, the maximum number of installed lights is 40.
Reduced to 0 lights. Furthermore, the installation intervals of the lighting fixtures are fixed,
When the light traveling speed is increased, the lighting cycle becomes shorter, so
The number of address data that can be transmitted is reduced, and the total number of installed lights is reduced.

[0013]
