Description of the Related Art Conventionally, a plurality of self-luminous line-of-sight guide marks installed along a road at intervals, for example, a self-luminous delineator, a self-luminous curve sign, a self-luminous road tack, etc., are used to synchronize the blinking of a light emitter. In order to perform simultaneous flashing and sequential flashing operations, for example, each self-luminous gaze target is equipped with a radio receiving circuit to receive the time signal and time signal of general broadcasting, and each person responds to the time signal. There is a method of synchronizing the blinking of the light-emitting body by operating the light-emitting gaze target.

However, in the above method, it is necessary to individually set the timing for synchronizing each self-luminous gaze target, and when the number is large, the work is difficult. In addition, even if one of the self-luminous gaze target has a setting error, it cannot be synchronized, and changing and setting the blinking pattern is troublesome. Furthermore, in the mountains and near the steel tower, there was a case where the signals of general broadcasting could not be received due to radio interference, and synchronization could not be achieved.

Therefore, the present invention solves the above problems,
We provide a synchronized flashing system for self-luminous eye gaze target that can easily synchronize flashing light emission, can easily change and set the flashing pattern on site, and can easily correct even if there is an error in the setting. It is something to do.

BEST MODE FOR CARRYING OUT THE INVENTION Next, embodiments of the present invention will be specifically described with reference to the drawings. That is, FIG. 1 is a block diagram showing a configuration of an embodiment of the present invention, and FIG. 2 is an operation time chart diagram of FIG.

In the form shown in FIG. 1, reference numeral 1 is a self-luminous delineator, which incorporates a light-emitting body such as a light-emitting diode or electroluminescence, a self-luminous curve sign,
It is a self-luminous line-of-sight guide such as a self-luminous road tack, and a plurality of (7 in this embodiment) are installed along the road at intervals. It is intended to allow the driver to recognize the road alignment, etc., and to drive the vehicle safely.

Reference numeral 2 denotes a master device, which can set a predetermined blinking pattern, and a signal generating function for generating a plurality of synchronized blinking control signals 21 by sequentially delaying and starting the set blinking pattern. And a transmission function capable of transmitting the blinking control signal 21.

Reference numeral 3 denotes a child device which is provided in each of the self-luminous line-of-sight guide marks 1 and causes the self-luminous line-of-sight guide mark 1 to blink based on a blinking control signal 21 transmitted from the master device 2. The slave device 3 has an address setting function capable of setting an address number corresponding to each blinking control signal 21 so that the blinking control signal 21 transmitted from the master device 2 can be selectively received for each address. And a receiving function for receiving the blinking control signal 21.

After the sunset, the master device 2 sends a plurality of synchronized blinking control signals 21 according to a preset blinking pattern to each child device 3, and each child device 3
The blinking control signal 21 corresponding to its own address number is selectively received, and each self-luminous line-of-sight guide mark 1 is made to blink and emit light based on the selectively received blinking control signal 21. By blinking the self-luminous line-of-sight guide mark 1 by blinking control signal 21 thus synchronized in advance, the blinking emission can be accurately synchronized. This self-luminous gaze guide 1
The blinking light emission of may be simultaneous blinking or sequential blinking.

The blinking control signal 21 may be transmitted to the child device 3 by radio or wire. Further, the child devices 3 are usually housed inside the self-luminous gaze guide 1, but the master device 2 may be housed inside the self-luminous gaze guide 1 or may be installed outside. When the master device 2 is housed inside the self-luminous gaze guide 1, the master device 2 may have the function of the address number 1.

According to the present embodiment, the master device 2 generates a predetermined blinking control signal 21 that is synchronized in advance, and each self-luminous gaze target 1 is blinked and emitted based on the blinking control signal 21. It is not necessary to set the timing for synchronizing the individual self-luminous gaze guides 1. Therefore, even if the number of the self-luminous gaze guides 1 is large, blinking light emission can be easily synchronized. The blinking pattern of can be easily changed and set, and even if there is a mistake in the setting, it can be easily corrected.

The operation of the embodiment shown in FIG. 1 will be described with reference to the operation time chart of FIG. In FIG. 2, as an example, the number of lighting groups (the number of times of lighting in one cycle) G = 5, the number of intervals (the number of times of turning off in one cycle) I
= 2, lighting time T = 0.5 seconds (1 blink cycle S = 1
The blinking control signal 21 is obtained when the blinking patterns are set to Δt = 1 second, and therefore the address numbers 1 to 7 of the respective slave devices 3 are indicated. The seven synchronized blinking control signals 21 corresponding to the number are transmitted from the master device 2.

Then, by these blinking control signals 21,
For example, first, the self-luminous gaze target 11 blinks by the child device 31 having the address number 1, and then, after 1 second, the address number 2
The self-luminous gaze guide 12 blinks by the child device 32 of the number,
Further, after one second, the self-luminous line-of-sight guide indicator 13 blinks, and similarly, the self-luminous line-of-sight guide indicators 14 to 17 blink sequentially. That is, each of the self-luminous gaze guides 11 to 17 has a delay time of 1
Accurately synchronized in seconds, the flashes are emitted sequentially.

In this case, the number of lighting groups G = 5 and the number of intervals I = 2 are set, and the delay time Δt is 1.
Since the same 1 second as the blinking cycle S, the self-luminous line-of-sight guide 1 blinking at a certain time among the seven self-luminous line-of-sight guides 1 is constantly turned off. There are two guide marks 1, and it seems that five self-luminous line-of-sight guide marks 1 flow sequentially and flash with a distance between the two guide marks. Of course, the number of lighting groups, the number of intervals, the lighting time, and the delay time may be appropriately determined in consideration of the number of self-luminous line-of-sight guide marks 1 to be installed, the installation interval, and the like.
