[Prior art]
2. Description of the Related Art Conventionally, for buildings, towers, chimneys, and the like having a height not less than the height specified by the Civil Aeronautics Act, for example, in the case of a building, an aviation obstacle light is installed when the height is 60 m or more. In particular, when the distance is 150 m or more, the installation of a medium-luminance red aviation obstacle light is obligatory.
[0003]
In the case of a tower or a chimney with a length of 60 m or more, in the case of a building painted with a daytime sign, at nighttime, a height of 90 m or more and less than 150 m requires the installation of a medium-luminance red aviation obstruction light. An example of the medium-luminance red aviation obstacle light is a blinking aviation obstacle light using an incandescent light bulb.
[0004]
For towers, bridge girders, and the like that are higher than the height stipulated by the Civil Aeronautics Law, for example, for properties that do not carry out daytime signs, the installation of medium-luminance white aviation obstacle lights or high-luminance obstacle lights is required. As an example of the medium-luminance white aviation obstacle light and the high-luminance obstacle light, there is a flash (flash-on) aviation obstacle light using a xenon lamp.
[0005]
However, in such conventional blinking or flashing aviation obstruction lights, a plurality of aviation obstruction lights installed in a plurality of buildings in a predetermined area are flickering or flashing separately for each building. In addition to the poor visual appearance of the neighboring residents and the fact that adjacent aviation obstruction lights repeatedly blink or flash sequentially within the predetermined area, it may appear as if the lighting is continuous, in this case May cause glare to nearby residents.
[0006]
Therefore, in the conventional aviation obstruction light system, a plurality of controllers are connected to each other in a wired manner in order to provide a plurality of aviation obstruction lights in a predetermined area with timing pulse signals for synchronizing their blinking and flashing, respectively. Some devices are configured to synchronize the blinking and flashing of a fault light.
[0007]
FIG. 7 is a functional block diagram of a plurality of controllers 2A, 2B, 2C,..., 2N in the conventional aviation obstacle light system 1 of this type. These controllers 2A to 2N are used to synchronize the flickering of a plurality of blinking aviation obstruction lights (not shown) arranged in a predetermined area with the plurality of controllers 2A to 2N in the predetermined area. The 2A to 2N synchronization units 3, 3,... Are connected by wired synchronization lines 4a, 4b,.
[0008]
These controllers 2A to 2N provide a thyristor control unit 6 to which power supply such as a commercial power supply is supplied via a breaker 5 and a thyristor of the thyristor control unit 6 for controlling the flickering of an aviation obstacle light. A blinking control unit 7 for giving a pulse signal to control on / off of the power supply; a photoelectric switch 9 for controlling the power supplied to the thyristor control unit 6 to turn on / off the power supply by a daylight sensor 8; And a synchronization unit for synchronizing the output timing pulse signals among the plurality of controllers 2A to 2N.

[0011]
Therefore, it is conceivable to solve the problem of securing land by connecting these synchronization lines 4b to 4n to, for example, an electric power tower provided with an aviation obstruction light. However, in this case, the synchronizing lines 4a to 4n approach the high-voltage transmission line and are affected by the high voltage, so that the noise increases, and a malfunction may occur in synchronizing the blinking of each aviation obstacle light.
[0012]
On the other hand, by configuring these connecting lines 4b to 4n by optical fibers, it is possible to reduce an increase in noise due to the high-voltage transmission line. However, this requires an expensive optical fiber, and also converts an electric signal from each synchronization unit 3 into an optical signal and transmits the signal through an optical fiber, and an optical signal transmitted through the optical fiber into an electric signal again. A new problem that complicates the configuration and increases the cost arises, such as the necessity of a photoelectric converter to be restored and provided to the synchronization unit 3.
