Description

Street light flashing control system

The present invention relates to a street light blink control system, and more particularly to a system for wirelessly controlling the blinking of a plurality of street lights installed on the road remotely.

In the conventional street lamp flashing control, the street lamp is tied to each section to connect the street lamp flashing control line to each section to turn on or off the street lamp for each section. In addition, it is installed for each section, the administrator has to manage the switching box for controlling the blinking of the street lamp of this section in time zones. At this time, each street light in each section is connected to the switching box of this section.

Therefore, a lot of costs are required for the wiring work for connecting the streetlight blinking control line to each section. In addition, since the street lights are turned on or off for each section, in order to turn on or turn off a specific street light, there is an inconvenience of directly operating a switching box of a specific section.

The present invention has been made to solve the above-mentioned drawbacks of the prior art, by installing a street lamp flasher on each of the street lamps installed on the road to provide the street lamp flashing information to the street lamp flasher wirelessly from the street lamp control device It is an object of the present invention to provide a street lamp blink control system to wirelessly control the blink of a street lamp.

In accordance with an aspect of the present invention, there is provided a street light control system including a street light control device and a street light flashing device, the street light control device including: a key input unit configured to key-in to control the blinking of a specific street light; A first micom extracting identifier information of the specific street light among a plurality of predetermined street light identifiers according to key input of the key input unit; And a transmitter for receiving the identifier information and the blinking information of the specific street light from the first micom and modulating and transmitting the modulated signal to the air. The apparatus for blinking a street light includes: a receiver for receiving and demodulating a modulated signal from the transmitter; A second micom that receives the identifier information and the blinking information of the specific street light from the receiving unit and receives the blinking information when the identifier information is the same as the identifier information thereof; A power supply unit supplying power for lighting the street lamp; And a switching unit configured to switch the power of the power supply unit to a predetermined bulb according to the blinking information of the second micom, so that the bulb is turned on or off.

Hereinafter, an embodiment of the present invention for achieving the above object will be described in detail.

Figure 1 is a schematic diagram for explaining the blinking of the street lamp on the road by the street lamp blink control system according to the present invention, a plurality of street lamps illuminating the road is wireless from the street lamp control device 10 shown in Figure 2 to be described later It is controlled by flashing and turns off or on respectively. At this time, the street lamp is generally erected at the edge of the sidewalk facing the driveway.

FIG. 2 is a block diagram illustrating an embodiment of the streetlight blinking control system according to FIG. 1, and includes a streetlight control device 10 and a streetlight blinking device 30. At this time, the street light control device 10 is composed of a key input unit 12, the microcomputer 14, the storage unit 16, the transmission unit 18, and the antenna 20. In addition, the street light blinking device 30 is composed of an antenna 32, the receiver 34, the microcomputer 36, the storage 38, the power supply 40, and the switching unit 42.

In the figure, the key input unit 12 in the street lamp control device 10 is keyed by the operator to provide a key signal to the microcomputer 14 for controlling the blinking of a specific street lamp.

The microcomputer 14 extracts identifier information of a specific street light from among a plurality of street light identifiers preset in the storage unit 16 according to a key input of the key input unit 12, and provides the same to the transmitter 18 along with flashing information of the street light. .

The storage unit 16 includes a memory such as an electrically erasable read only memory (EEROM), and stores and extracts a plurality of streetlight identifiers under the control of the microcomputer 14.

The transmitter 18 receives the identifier information and the blinking information of the specific street light from the microcomputer 14 and modulates it to be transmitted to the air through the antenna 20. At this time, it is necessary to limit the frequency and output magnitude of the modulated signal of the transmitter 18 to fall within a specific value range.

The receiver 34 in the street lamp blinking device 30 receives and demodulates a modulated signal from the transmitter 18 through the antenna 32 to provide the identifier information and the blinking information of the specific street lamp to the microcomputer 36.

The microcomputer 36 receives the identifier information and the blinking information of the specific street light from the receiver 34 and receives the blinking information when the identifier information is the same as its identifier information previously stored in the storage 38.

The storage unit 38 is composed of a memory such as an electro-erasing ROM and stores and extracts its identifier information under the control of the microcomputer 36.

The power supply unit 40 supplies power for lighting the street lamp.

The switching unit 42 turns on or turns off its own street light bulb by switching the power of the power supply unit 40 according to the flashing information of the microcomputer 36.

3 is a flow chart showing step by step the operation of the street lamp blinking control system according to FIG.

First, the microcomputer 36 in the street lamp blinker 30 monitors the airwaves through the antenna 32 and the receiver 34 to determine whether a signal of a specific waveband is received (step 50).

When the signal of the specific frequency band is received in the step 50, it is determined whether there is identifier information of its own by modulating the signal of the specific frequency band (step 52).

If there is the identifier information of its own in step 52, it is determined whether the following information is lighting information or lighting out information (step 54).

When the information subsequent to the step 54 is lighting information, the switching unit 42 is turned on so that the power of the power supply unit 40 is applied to the bulb to light the street lamp (step 56).

On the other hand, when the information following step 54 is the extinction information, the switching unit 42 is turned off so that the power of the power supply unit 40 is not applied to the bulb so that the street light is turned off (step 58).

As described above, in the above-described invention, the wireless pager may be installed in the street lamp blinker 30 so that when the lighting information is received at the same time as the wireless call, the switching unit 42 may supply power to the bulb to light the bulb. In addition, when the extinguished information is received instead of the above-described lighting information, the light bulb may be turned off so that the switching unit 42 does not supply power to the bulb. As such, when the wireless pager is used in the present invention, the present invention can be put to practical use at a low cost.

In addition, by applying the street lamp flashing control system according to the present invention to a plurality of street lights can be set to the same identifier for each street lamp to turn on or off the street lights for each section.

As described above, the present invention provides street lamp blinking device 30 wirelessly from street lamp controlling device 10 by installing street lamp blinking device 30 on each street lamp installed on the road, respectively. Control the blinking of the street light remotely. Therefore, there is an effect that can control the flashing of the street light quickly and accurately. In addition, when the weather is very cloudy during the day and the street becomes dark, such as at night, the street lamp can be quickly turned on to prevent various safety accidents.
