Visual guidance light control system}

The present invention relates to a system for controlling a plurality of line-of-sight guidance lights installed along a road, and more particularly, by photographing infrared rays emitted from a certain distance and measuring and analyzing the intensity of the photographed infrared rays to determine the current fog concentration. It relates to a control system that allows the output control of a line of sight induction, etc. to be stably performed using a power line.

In general, a plurality of line guide lights may be installed on both sides of a road on which vehicles pass for the purpose of preventing accidents in a situation in which it is difficult for a driver to secure a field of view due to thick fog.

Since these line guide lights are mainly configured to secure power for operation using solar energy, they have the effect of securing continuous power in normal times, but cannot be charged in situations where bad weather continues for a long time, so eventually the battery may be discharged and a problem may occur in which it cannot perform its function.

In addition, due to the nature of the battery, there is a problem of performance deterioration as charging and discharging are repeated, and there is a problem that it does not work even in thick fog due to a failure in wireless communication with the visibility system used for detecting fog. can happen

In addition, a problem that is not helpful to the driver due to the brightness of light that is weak compared to the concentration of fog may occur, or a problem that the brightness of light that is strong compared to the concentration of fog rather interferes with the driver's vision may occur.

Therefore, it is necessary to solve the above problems, and for this purpose, Korean Patent Registration No. 10-0243074 “Apparatus and method for adjusting the brightness of fog warning lights” and Korean Patent Registration No. 10-1807227 “Self-illuminated line guide light device” and control method” have been proposed and disclosed.

That is, the Korean Patent Registration No. 10-0243074, "Apparatus and method for adjusting the brightness of fog warning lights," is configured to detect the concentration of fog occurring on the road and adjust the brightness of the fog lights based on the detected concentration. An invention related to a device and method that can help a driver's safe driving in a situation where an error occurs has been proposed.

In addition, the Korean Patent Registration No. 10-1807227, “Self-illuminated gaze guide light device and control method” is configured to secure continuous power by wind power generation and solar power generation using the driving wind of the vehicle, and lighting according to the weather An invention related to a device and a control method configured to secure a driver's visibility of a road boundary in a method such as changing the color of a color has been proposed.

However, the prior inventions as described above do not propose a solution to the failure situation of wireless communication, and are configured to use even wind power generation for the purpose of securing stable power, so that some of the above problems cannot be solved or effective. It is confirmed that the limit occurs only in a limited way.

Therefore, by solving all the above problems, it is possible to stably secure power even in a situation where the weather is bad, maintain a stable communication connection, and implement lighting of appropriate brightness according to the concentration of fog. There is a need for a new invention related to a line of sight induction lamp configured to be able to.

Republic of Korea Patent Registration No. 10-0243074 (1999. 11. 15) Republic of Korea Patent Registration No. 10-1807227 (2017. 12. 04)

There is a need for a line guidance light configured to stably secure power, maintain a stable communication connection, and realize lighting of appropriate brightness according to the concentration of fog even in a situation where the weather is deteriorating. Since it has been done, the purpose is to suggest a solution to this.

In the present invention, infrared rays (or lasers) transmitted from a certain distance are photographed, and the intensity of the captured infrared rays is measured and analyzed so that the output control of the gaze guidance light according to the current fog concentration can be stably performed using a power line Regarding the control system,

A plurality of gaze guide lights 100 that receive a control signal transmitted by the light emitting unit 110 in a state installed along a road through which a vehicle passes, and illuminate with an output corresponding to the received control signal; In a state installed at a certain height, a plurality of infrared rays or lasers are sent out in a horizontal direction, and the intensity of infrared or laser output is adjusted or maintained by receiving a maintenance or change signal transmitted by the photographing unit 120, and a response corresponding to the maintenance signal a light emitting unit 110 generating a control signal according to the intensity of an output greater than a reference value and transmitting the generated control signal to the line guidance lamp 100; And, in a state installed at the same height as the light emitting unit 110, photographing infrared rays or laser beams transmitted in a horizontal direction, analyzing the intensity of the captured infrared rays or laser beams, and generating a maintenance or change signal according to the analyzed intensity a photographing unit 120 transmitting to the light emitting unit 110; It is characterized in that it is configured to include.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, as shown in FIG. 1A, the line guide light 100 is a device for lighting installed at regular intervals along the road where vehicles pass, and is mainly installed in a section where fog often occurs, as shown in FIG. 1B. Even in the same thick fog situation, the driver can clearly recognize the boundary line of the road.

At this time, the gaze guidance lamp 100 may be automatically controlled and illuminated in a situation in which fog of a certain concentration or more occurs, and the intensity of lighting may be automatically adjusted according to the concentration of fog.

However, the use of the gaze guidance light 100 is not limited to being used only in foggy situations, and may be configured to be automatically controlled and illuminated at night or in bad weather conditions.

In addition, the line-guided lamp 100 has a circular shape as a whole, and a plurality of LEDs constituting the inner circle of the center and a plurality of LEDs constituting the outer circle of the outer circle are individually controlled in a state where they are installed at different angles to emit surface light. By doing so, visibility can be improved and at the same time obstruction of the driver's vision can be minimized.

In addition, the gaze guidance lamp 100 is supplied with power using a power line instead of a method of securing power for lighting using solar power or wind power and a method of receiving a control signal for lighting through wireless communication. At the same time, it is configured to receive a control signal, and as a result, power can be stably secured even in a situation where the weather is bad, and the effect of maintaining a stable communication connection occurs.

In addition, as shown in FIG. 2, the light emitting unit 110 is a device for transmitting infrared rays or lasers installed at a certain height in the section where the line guidance lamp 100 is installed, and emits a plurality of infrared rays or lasers in a horizontal direction. It is configured to be transmitted so that it can be used to check the concentration in a situation where fog occurs in the corresponding section.

At this time, the light emitting unit 110 may operate at all times or for a predetermined period of time to transmit a plurality of infrared rays or laser rays. Intensity can be automatically adjusted.

However, the intensity of the output is not adjusted by operating alone, and the intensity of the output may be adjusted in connection with the change in infrared or laser imaging sensitivity of the photographing unit 120 according to the generation of fog and the change in concentration.

More specifically, the light emitting unit 110 transmits a plurality of infrared rays or laser rays in a horizontal direction in a state installed at a certain height, and receives a maintenance or change signal transmitted by the photographing unit 120 to generate infrared rays or laser output. configured to maintain or regulate strength.

That is, since there is no need to adjust the infrared or laser output intensity in normal times when there is no fog, the photographing unit 120 transmits a maintenance signal, but when fog occurs, the change signal transmitted by the photographing unit 120 is received. , a corresponding adjustment of the intensity of the infrared or laser output occurs.

Therefore, in a situation where fog occurs, a change signal may be received once or several times according to the concentration of the fog, and thus the intensity of infrared or laser output may be adjusted. Infrared light or laser light with the same or similar intensity as usual may be captured, and a sustain signal is generated and transmitted to the light emitting unit 110 accordingly.

In addition, when the light emitting unit 110 increases the intensity of the infrared or laser output in response to the change signal transmitted by the photographing unit 120 and the sustain signal is received, the infrared or laser output corresponding to the sustain signal is received. It is configured to generate a control signal according to the intensity of the output, that is, the intensity of a reference value or more, and transmit it to the line guidance lamp 100.

That is, since the maintenance signal generated by the photographing unit 120 is a signal generated at an infrared or laser output intensity that is less than a preset reference value in normal times when there is no fog, generation of a control signal by the light emitting unit 110 is difficult. Since the maintenance signal generated by the photographing unit 120 in a situation where fog does not occur but is generated at an infrared or laser output intensity higher than a reference value is generated, a control signal is generated by the light emitting unit 110 and the gaze guidance lamp 100 transfer takes place.

Therefore, in the line guide light 100, the control signal transmitted by the light emitting unit 110 is received, and the lighting with the output corresponding to the received control signal is immediately generated so that the driver can drive on the road even in a foggy situation. to clearly recognize the boundaries of

On the other hand, as shown in FIG. 3A, the light emitting unit 110 is provided with a blower (a) for blowing upwards for the purpose of dust removal and an air blower (b) in the shape of a L in the inner hollow, the blower One or more tuyeres (c) for sending out the wind transported through (b) in a horizontal direction are formed on the upper edge of the front surface, and the sunlight incident on the front surface for the purpose of preventing infrared rays or laser scattering by sunlight. It may be configured in a form including a housing 111 provided with a shield d for blocking light.

In addition, as shown in FIG. 3A, the light emitting unit 110 is composed of a plate shape in which a plurality of LEDs emitting infrared rays or lasers are disposed, and a light emitting module unit 112 installed on the front surface of the housing 111. ).

In addition, as shown in FIG. 3B, the light emitting unit 110 outputs a plurality of LEDs disposed in the light emitting module unit 112 based on a maintenance or change signal transmitted by the photographing unit 120. It may be configured in a form including an LED control unit 113 to control.

In addition, as shown in FIG. 3B, the light emitting unit 110 includes a generation unit 114 for generating a control signal according to an intensity of infrared or laser output equal to or higher than a reference value corresponding to the received sustain signal, and the photographing unit ( 120) may be configured to include a communication unit 115 that receives a maintenance or change signal transmitted and transmits a control signal generated by the generation unit 114 to the gaze guidance lamp 100.

That is, the housing 111 is configured to have a shield on the front surface on which the light emitting module unit 112 is vertically installed, so that a plurality of LEDs are protected from rain, snow, and dust scattered by vehicle driving. and minimize the scattering of infrared rays or lasers by sunlight.

In addition, the housing 111 allows the wind generated by the blower inside to be discharged to the outside through the air passage and the tuyere so that the flow of air inside the shield can be smoothly generated.

In addition, since the inflow of dust scattered by the driving of the vehicle cannot be completely blocked, the inflow of dust inevitably continues to occur inside the shield.

At this time, since the flow of air by the shield is stagnant at the front side of the light emitting module unit 112, the concentration of dust introduced into the shield continues to increase, and as a result, the photographing unit 120 There may be a misunderstanding of the situation in which it occurred.

Therefore, the present invention allows the wind generated by the blower inside the housing 111 to be strongly discharged to the outside through the air passage and the tuyere so that the flow of air inside the screen can be smoothly generated, as described above. It is possible to prevent a problem of occurrence of errors due to an increase in dust concentration.

In addition, the light emitting module unit 112 is configured in the shape of a disc or square plate in which a plurality of LEDs are integrally disposed in a circular shape or a square shape, so that installation, wiring, and replacement to the housing 111 are easy. can be done easily

In addition, the LED controller 113 may be provided in the inner hollow of the housing 111, and as shown in FIG. 4, a plurality of LEDs of the light emitting module unit 112 respond to a maintenance signal normally received. transmits infrared rays or lasers of a predetermined intensity in the horizontal direction, but in a situation in which fog occurs and the change signal transmitted by the photographing unit 120 is received, the intensity of the output is adjusted until a new maintenance signal is received can be controlled as much as possible.

Accordingly, the plurality of LEDs may be composed of infrared LEDs for emitting infrared rays, but may also be composed of laser LEDs for emitting laser rays.

At this time, the LED controller 113 may increase the intensity of the output step by step each time a new change signal is received until the sustain signal is received, and from the time when the intensity of the output sufficiently increases and the sustain signal is received The intensity of the output at the point in time may be maintained.

Of course, in a situation where the change signal transmitted from the photographing unit 120 is received again because the fog is thicker, the intensity of the output must be controlled to be adjusted until a new sustain signal is received.

In addition, the intensity of the output may be lowered step by step after a predetermined time has elapsed in a situation in which the maintenance signal is continuously received a predetermined number of times or more, or the maintenance signal is continuously received.

However, when a change signal is received during the adjustment of the output intensity, the intensity of the output may be increased step by step until a sustain signal is received again, and the state may be maintained for a predetermined time.

Therefore, the present invention has an effect of minimizing unnecessary power consumption due to lighting by responding quickly to a situation in which fog is generated and gradually becomes thicker as well as a situation in which fog gradually disappears.

In addition, the generation unit 114 may also be provided in the inner hollow of the housing 111, and generates a control signal according to the intensity of infrared or laser output equal to or higher than a reference value corresponding to the maintenance signal received by the communication unit 115. As a result, illumination with a luminous intensity corresponding to the current visibility distance can be generated.

Accordingly, as an embodiment of the present invention, the generating unit 114 generates a control signal for enabling the line guidance lamp 100 to illuminate with a luminous intensity of 220 cd in a state where the current visibility range is greater than or equal to 71 m and less than 80 m. In a state where the current visibility distance is in the range of 61 m or more and less than 70 m, a control signal for enabling the line guidance lamp 100 to illuminate with a luminous intensity of 350 cd may be generated.

In addition, the generating unit 114 may generate a control signal to enable the line guidance lamp 100 to illuminate with a luminous intensity of 540 cd when the current visibility distance is in the range of 51 m or more and less than 60 m, and In a state where the distance is in the range of 41 m or more and less than 50 m, a control signal may be generated to enable the line guide lamp 100 to illuminate with a luminous intensity of 840 cd.

In addition, the generating unit 114 may generate a control signal that enables the line guidance lamp 100 to illuminate with a luminous intensity of 1,310 cd in a state where the current visibility distance is in the range of 31 m or more and less than 40 m, In a state where the visibility distance is in the range of 21 m or more and less than 30 m, a control signal enabling the line guide lamp 100 to illuminate with a luminous intensity of 2,050 cd may be generated.

In addition, the generation unit 114 may generate a control signal that enables the line guidance lamp 100 to illuminate with a luminous intensity of 3,200 cd when the current visibility distance is 20 m or less, and the communication unit 115 generates the generated By transmitting a control signal to the gaze guiding light 100, lighting according to a value included in the control signal can be generated.

At this time, as described above, the line guidance lamp 100 is divided into a plurality of LEDs constituting the inner circle of the center and a plurality of LEDs constituting the outer circle of the outer periphery. It is a value output by a plurality of LEDs constituting the outer source, and it is preferable that the plurality of LEDs constituting the inner source illuminate with a luminous intensity of 80% or less compared to the luminous intensity output by the plurality of LEDs constituting the external source.

On the other hand, the light emitting unit 110 also supplies power through a power line instead of a method of having a single power supply device and a method of receiving a maintenance signal for maintaining output intensity and a change signal for adjusting output intensity through wireless communication. It is configured to receive a maintenance signal or a change signal at the same time as being supplied, and as a result, power can be secured stably, and the effect of stably maintaining the connection state of communication occurs.

In addition, the photographing unit 120 is a multi-functional device installed at a certain height in the section where the line-of-sight guidance lamp 100 is installed, and performs infrared or laser imaging and analysis of intensity and control of the light emitting unit 110 accordingly. It is configured so that it can be used for response according to the concentration in a situation where fog occurs in the corresponding section.

That is, as shown in FIG. 2, the photographing unit 120 is configured to photograph a plurality of infrared rays or laser beams emitted by the light emitting unit 110 in a horizontal direction, and analyzes the intensity of the infrared rays or laser images. It is configured to be able to generate and transmit a maintenance or change signal according to the analyzed intensity to the light emitting unit 110 .

Therefore, as described above, in the light emitting unit 110, the intensity of infrared or laser output using a plurality of LEDs can be increased step by step, and eventually, the photographing unit 120 is the same as usual without the occurrence of fog. Alternatively, infrared rays or lasers of similar intensity may be photographed.

More specifically, as shown in FIG. 5, the photographing unit 120 includes a photographing module unit 121 for photographing a plurality of infrared rays or laser beams emitted by the light emitting part 110 in a horizontal direction, captured infrared rays or The analysis unit 122 analyzes the intensity of the laser, generates a change signal for controlling the output of the light emitting unit 110 when the intensity below the reference value is analyzed, and emits light when the intensity that satisfies the reference value is analyzed. Includes a corresponding unit 123 generating a sustain signal for maintaining the output of the unit 110 and a transmission unit 124 transmitting the sustain or change signal generated by the corresponding unit 123 to the light emitting unit 110 It can be configured in the form of

That is, in normal times when there is no fog, the intensity of infrared rays or lasers photographed by the photographing module unit 121 and analyzed by the analyzer 122 may be maintained within a certain range equal to or greater than a predetermined reference value.

At this time, as shown in FIG. 6, since the intensity that satisfies the reference value is being measured, the corresponding unit 123 generates a maintenance signal for maintaining the infrared or laser output intensity by the light emitting unit 110. , The transmitting unit 124 may transmit the generated sustain signal to the light emitting unit 110 so that the intensity of infrared or laser output may be maintained.

However, in a foggy situation, the intensity of infrared rays or lasers photographed by the photographing module unit 121 and analyzed by the analysis unit 122 falls short of a preset reference value, and the corresponding unit 123 generates a change signal. The transmission unit 124 may transmit the generated change signal to the light emitting unit 110 so that the intensity of infrared or laser output may be adjusted.

Therefore, as described above, in the light emitting unit 110, the intensity of infrared rays or laser output using a plurality of LEDs can be increased step by step, and as a result, the intensity of infrared rays measured as less than the reference value reaches the reference value. or exceeding the reference value.

On the other hand, it is preferable that the photographing unit 120 is configured to check the number of pixels where infrared light or laser is photographed in real time or at regular intervals, and through this, an automatic inspection function can be implemented.

That is, since the light emitting unit 110 and the photographing unit 120 are installed along the road, a strong draft or collision of a vehicle may cause the initially set position to be distorted. In this case, the fog is thick. Determination of may occur, and generation of a change signal by the photographing unit 120 may occur, and accordingly, unnecessary infrared or laser output adjustment may occur.

Therefore, the photographing unit 120 checks the number of pixels where infrared rays or lasers are photographed in real time or at regular intervals, and when the number of checked pixels decreases below a certain rate, a notification message is generated and a unique identification number is displayed. By being configured to transmit to the set administrator terminal, a slight distortion can be allowed, but if more distortion occurs, maintenance by the manager can be performed.

In addition, the photographing unit 120 is also configured to transmit a maintenance or change signal while being supplied with power through a power line, instead of a method of having a single power supply and a method of transmitting a maintenance or change signal through wireless communication. As a result, power can be secured stably, and the effect of stably maintaining the connection state of communication occurs.
