In the accompanying drawings, in order to more clearly express the technical idea of the present invention, parts that are not related to the technical idea of the present invention or can be easily derived from those skilled in the art, such as wire arrangement, are simplified or omitted.

First of all, to define the term for the direction, in FIG. 1, the vertical direction may mean the height direction, the direction from one fastening member to the other fastening member may mean the longitudinal direction, and the height A direction and a direction orthogonal to the longitudinal direction may mean the width direction.

The lateral direction is a direction orthogonal to the height direction, and may collectively refer to the longitudinal direction and the width direction.

As shown in FIGS. 1 to 10 , the lane display device 10 according to an embodiment of the present invention may be a device installed on a road to more clearly display a lane to a driver.

For example, the lane display device 10 forms a predetermined arrangement space and includes a case part 100 installed and fixed to the road by the fastening member T, and a light emitting part 200 disposed in the arrangement space and emitting light , a GPS receiving unit 300 disposed in the arrangement space and receiving GPS information including first time information, a control unit 400 controlling light emission of the light emitting unit 200 based on the first time information, and the A cover part 500 covering the placement space may be included.

For example, the case unit 100 is installed and fixed to a road by fastening the fastening member T, and may be configured to form the arrangement space.

For example, the fastening member (T) may be a high-strength bolt, anchor, etc., but is not limited thereto and may be variously modified from the standpoint of those skilled in the art.

For example, the light emitting unit 200 is a component that emits light by electric energy, and may be an LED.

For example, the light emitting unit 200 may be disposed on the arrangement space to emit light upward in the height direction.

The cover part 500 is configured to cover the arrangement space, and may be fixed to the case part 100 by fastening parts (not shown) such as screws and bolts, and the case part 100 by being fitted. may be fixed to

For example, the GPS receiving unit 300 is a configuration disposed adjacent to the light emitting unit 200 on the placement space, and is not a configuration that simply counts time, but in real time from GPS satellites and / or GPS base stations. It may be configured to receive the GPS information including first time information.

As a result, the first time information obtained by the GPS receiving unit 300 has an effect in that a time error does not occur even after time passes.

For example, the control unit 400 is a component that realizes flickering of the light emitting unit 200 based on the first time information obtained from the GPS receiving unit 300, and is integrally formed with the GPS receiving unit 300. and may be placed on the placement space, or may be placed on the placement space as a separate configuration from the GPS receiver 300.

For example, the control unit 400 may realize flickering of the light emitting unit 200 at predetermined time intervals based on the first time information.

The blinking at predetermined time intervals may mean that the light emitting unit 200 is repeatedly turned off and turned on in a predetermined pattern.

To explain this in more detail, for example, as shown in FIG. 3 , four lane display devices 10 may be installed on a road.

Here, FIG. 3(a) shows that the lane display device A1 installed in an odd column turns on and the lane display device A2 installed in an even column turns off, and FIG. 3(b) shows the lane display device A1 installed in an odd column It is shown that the display device A1 is turned off and the lane display device A2 installed in an even numbered column is turned on, and as can be seen in FIGS. 3(a) and 3(b), the lane display device installed in an odd numbered column ( A1) may be turned on at odd seconds and turned off at even seconds, such as turning on at 1 second out of 60 seconds, turning off at 2 seconds, turning on at 3 seconds and turning off at 4 seconds.

On the other hand, the lane display devices A2 installed in even-numbered rows are turned on at even seconds and turned off at odd seconds, such as turning off at 1 second, turning on at 2 seconds, turning off at 3 seconds and turning on at 4 seconds out of 60 seconds. can

As a result, the plurality of lane display devices 10 installed on the road have no time error in that the light emitting unit 200 blinks based on the first time information obtained from the GPS receiver 300. Flickering of the light emitting unit 200 may be implemented.

For example, the time interval may be changed by the user as a criterion of when the lights are turned on and off.

Here, as an example, the lane display device 10 may further include an information display unit 600 displaying information about the time interval.

For example, the information display unit 600 is displayed on the case unit 100 or the cover unit 500, and '1' is displayed on the case of the lane display device A1 installed in an odd-numbered column. '0' may be displayed on the case of the lane display device A2 installed in an even-numbered column.

Therefore, the user can recognize the information display unit 600 and install the lane display device 10 on the road as intended by the blinking pattern of the light emitting unit 200 .

Here, as an example, the lane display device 10 may further include a photovoltaic power generation unit 700 that generates power to supply power to the GPS receiver 300 and the light emitting unit 200. The photovoltaic power generation unit 700 may include a solar cell 710 that converts light energy into electrical energy and a battery unit 720 that stores electrical energy.

Electrical energy stored in the battery unit 720 may be supplied to components requiring electrical energy, such as the GPS receiver 300, the light emitting unit 200, and the control unit 400.

At this time, as an example, the cover part 500 may form a recessed space S4 in which the solar cell 710 is disposed.

For example, the recessed space S4 may be formed on an upper side of the cover part 500 in the height direction, and the solar cell 710 is disposed on the recessed space S4 to cover the cover part 500. ) to be protected from the external environment in the lateral direction.

The battery unit 720 may be disposed in the placement space, and the cover part 500 may cover the placement space to protect the battery unit 720 from the external environment.

For example, the cover part 500 is formed on the cover main body part 510 forming the recessed space S4 and the cover main body part 510, so that the electrical energy produced by the solar cell 710 is stored in the cover body part 510. A cover through-hole H2 into which wires passing to the battery unit 720 are inserted may be provided.

Here, as an example, in the lane display device 10, a lane display unit 900 for displaying a lane to a driver is detachable, and the lane display unit 900 is fixed to a predetermined position on the case unit 100. A connection unit 800 linking the connection between the display unit 900 and the case unit 100 may be further included.

For example, the connection unit 800 may be detachable from the case unit 100 and detachable from the lane display unit 900 .

For example, the connection part 800 may be made of rubber or synthetic resin material having a predetermined elasticity to implement sealing.

Here, as an example, the cover part 500 may form an incision space S5, and the linkage part 800 slides on the incision space S5 to be attached to and detached from the case part 100, It may cover the placement space.

For example, the cover body part 510 may form the incision space S5, and the arrangement space may be exposed to the outside through the incision space S5.

At this time, the linkage part 800 can be slid in the width direction on the incision space S5 and fixed to the case part 100, and covers the arrangement space so that components disposed on the arrangement space can be removed. It can be protected from the external environment.

For example, the connection part 800 extends upward in the height direction from the connection main body 810 sliding on the incision space S5 and the connection main body 810, and the lane display unit 900 is mounted. A connection extension part 820 may be provided.

For example, the connection extension unit 820 may form a connection space S6 so that light emitted from the light emitting unit 200 disposed on the arrangement space moves to the lane display unit 900 .

As a result, the connection unit 800 links the connection between the lane display unit 900 and the case unit 100 and at the same time covers the placement space to protect it from the external environment, and furthermore, the light emitting unit 200 The emitted light may have a function of moving upward in the height direction.

For example, the connection part 800 is constrained to the case part 100 in the lower side in the height direction, and constrained to the cover part 500 in the upper side in the height direction, so as to obtain a predetermined value on the case part 100. Can be fixed in position.

For example, the connection part 800 may further include a connection step part F formed as a step on the edge of the connection body part 810, and the cover part 500 is the incision space S5 ) It may be provided with a cover step portion (E) formed as a step on the edge of the cover body portion 510 forming a.

As a result, the step-difference part F may come into contact with the step-difference part E of the cover while sliding onto the step-difference part E of the cover, and be constrained by the step-difference part E of the cover.

When the linkage step portion F is constrained to the cover step portion E, the linkage portion 800 is constrained to the case portion 100 to the lower side in the height direction and to the cover portion 800 to the upper side in the height direction. It is constrained to the part 500 and can be fixed to a predetermined position of the case part 100 .

Also, the connection part 800 may be constrained to the case part 100 and the cover part 500 in the lateral direction.

That is, the connection main body 810 may be in contact with the case 100 and the cover main body 510 in the lateral direction so that positional movement may be restricted.

Here, as an example, the case part 100 may include a body part 110 forming the arrangement space and a protrusion part 140 protruding upward from the body part 110 in the height direction.

Here, the connection part 800 may form a connection groove S7 into which the protrusion 140 can be inserted.

For example, when the connecting part 800 is slid and inserted into the incision space S5, the protruding part 140 is inserted into the connecting groove S7 so that the connecting main body part 810 is the case part. It can be fixed to a predetermined position on (100).

Here, as an example, the arrangement space formed by the case part 100 is a first arrangement space S1 where the light emitting unit 200 and the GPS receiver 300 are disposed, and the battery unit 720 is disposed. a second arrangement space (S2) and a third arrangement space (S3) forming a connection path so that the wire connected to the battery unit 720 is connected to the light emitting unit 200 and the GPS receiver 300. can

That is, the body part 110 may form the first arrangement space S1, the second arrangement space S2, and the third arrangement space S3, and the light emitting part 200, the GPS The receiver 300 and the control unit 400 are disposed in the first arrangement space S1, the battery unit 720 is disposed in the second arrangement space S2, and wires are disposed in the third arrangement space ( S3) can be placed.

For example, the first placement space S1 may be formed in a central region of the body 110, and the second placement space S2 extends from the first placement space S1 to both sides in the longitudinal direction. A plurality of them may be spaced apart from each other, and the third arrangement space S3 may be formed as a space in which the first arrangement space S1 and the second arrangement space S2 communicate with each other.

For example, the cutout space (S5) may be formed at a position overlapping the first placement space (S1), and the linkage part 800 is disposed on the cutout space (S5) to the first placement space (S5). (S1) can be arranged on the upper side.

The cover part 500 may be connected to the upper side of the case part 100 to cover the second arrangement space S2 and the third arrangement space S3.

For example, the case part 100 protrudes from the lower surface 120 defining the first arrangement space S1 and extends upward in the height direction from the lower surface 120 to support the light emitting part 200. The support surface 130 and the lower surface 120 form a step difference and may further include a stepped surface D supporting the GPS receiver 300 and/or the control unit 400.

For example, the support surface 130 may support the light emitting part 200 so that the light emitting part 200 is spaced apart from the lower side surface 120 .

As a result, even if rainwater flows into the lower surface 120 , the light emitting part 200 may not come into contact with rainwater.

In addition, since the stepped surface D forms a step from the lower surface 120 upward in the height direction, even if rainwater flows into the lower surface 120, the GPS receiver 300 and / or the control unit ( 400) can be prevented from contacting rainwater.

Here, as an example, the case part 100 discharges rainwater flowing into the first to third arrangement spaces S1, S2, and S3 to the ground, and at the same time, the electric wires run through the third arrangement space S3. A discharge hole H1 forming a passage leading from ) to the first arrangement space S1 may be formed.

For example, the discharge hole H1 may be a space in which the third disposing space S3 and the first disposing space S1 communicate with each other and at the same time may be a space capable of discharging rainwater to the ground.

The inflow of rainwater into the second and third arrangement spaces S2 and S3 is prevented by the cover part 500, and rainwater flows into the first arrangement space S1 by the connection part 800. Although the inflow is prevented, if rainwater flows into the first arranging space S1, the second arranging space S2 and/or the third arranging space S3, the rainwater flows through the discharge hole H1. ) through which it can fall to the ground and be discharged.

For example, the lane display device 10 may further include the lane display unit 900 attached to or detached from the linkage unit 800 .

For example, the lane display unit 900 is disposed on the display body 910 forming a movement space S8 in which the light emitted from the light emitting unit 200 moves and the movement space S8 to emit light. Reflective kissing may include a reflector 920 .

For example, light emitted from the light emitting unit 200 disposed in the first arrangement space S1 may pass through the connection space S6 and move onto the movement space S8.

For example, the reflector 920 may be disposed above the display body 910 in the height direction to reflect light.

11 is a schematic perspective view showing another embodiment of the linking part 800, a linking body part A810 sliding on the incision space S5 and a linking extension part forming the linking space S6. (A820) may be provided.

For example, the connection extension part A820 may be formed in the shape of a corrugated pipe, and as a result, the lane display unit 900 connected to the connection extension part A820 is formed by the wrinkles of the connection extension part A820. may not be easily broken by

12 is a schematic perspective view showing another embodiment of the case part 100, the same as the case part 100 described above, or descriptions of parts that can be easily inferred from those skilled in the art are omitted or briefly described. would.

As shown in FIG. 12, the case part A100 has a first placement space AS1 where the light emitting part 200 and the GPS receiver 300 are placed, and a second placement space where the battery part 720 is placed. (AS2) and a third arrangement space (AS3) forming a connection path so that the wire connected to the battery unit 720 is connected to the light emitting unit 200 and the GPS receiver 300 may be provided.

Here, a discharge hole AH1 may be formed on the third arranging space AS3 to discharge rainwater introduced into the first to third arranging spaces AS1 , AS2 , and AS3 to the ground.

That is, rainwater flowing into the first to third placement spaces AS1 , AS2 , and AS3 may fall to the ground through the discharge hole AH1 and be discharged.

Hereinafter, the control of the light emitting unit 200 will be described in more detail with reference to FIG. 13 .

For example, the control unit 400 may sense electric energy obtained from the photovoltaic power generation unit 700 and control ON/OFF of the driving of the light emitting unit 200 based on the obtained electric energy. .

Here, the meaning of ON/OFF of the driving of the light emitting unit 200 may be a meaning different from flickering of the light emitting unit 200 at predetermined time intervals described above.

To explain this in more detail, OFF of the driving of the light emitting unit 200 may mean a state in which the light emitting unit 200 is continuously turned off, rather than repeatedly turning on and off at predetermined time intervals, , ON of the driving of the light emitting unit 200 may mean a state in which the light emitting unit 200 is turned on and off repeatedly at predetermined time intervals as described above.

Here, as an example, the control unit 400 may sense electrical energy obtained from the photovoltaic power generation unit 700 .

For example, the controller 400 may include an ammeter and/or a voltmeter capable of sensing the electric energy.

For example, the control unit 400 may indirectly determine the level of sunlight based on the amount of electrical energy obtained.

That is, the controller 400 may determine that it is night when there is little or no electrical energy to be acquired, and may determine that it is day when there is a lot of electrical energy to be obtained.

As a result, the control unit 400 senses the electrical energy obtained based on a predetermined energy value, and determines that there is sunlight when the obtained electrical energy is greater than the predetermined energy value, and the predetermined energy value If it is less than the value, it can be determined that there is no sunlight.

At this time, the control unit 400 can turn off the driving of the light emitting unit 200 by determining that sunlight is relatively present, that is, determining that it is day when the obtained electric energy is equal to or greater than the predetermined energy value.

As a result, the light emitting unit 200 may be continuously maintained in a non-lighting state, rather than repeatedly turning on and off at predetermined time intervals.

On the other hand, the control unit 400 can turn on the driving of the light emitting unit 200 by determining that sunlight is relatively absent, that is, at night, when the obtained electrical energy is equal to or greater than the predetermined energy value.

As a result, the light emitting unit 200 may be turned on and off repeatedly at predetermined time intervals.

Here, as an example, the lane display device may further include a timer unit (not shown) having second time information.

For example, the timer unit may be disposed on the first arrangement spaces S1 and AS1.

For example, the timer unit is a component including the second time information and may be a separate component distinguished from the GPS receiving unit 300 that acquires the first time information.

For example, the timer unit may be an RTC module (Real Time Clock Module), and the second time information may mean information about time provided by the RTC module.

That is, the first time information is information about time obtained from a GPS satellite and/or a GPS base station in real time, and the second time information is information about time counted and acquired by an RTC module included in the lane display device. may be information.

For example, the RTC module may have the second time information continuously for 24 hours.

Here, as an example, an error may occur between the second time information provided by the timer unit and the first time information due to an unintentional supply of power to the timer unit or a failure/error of the timer unit.

Meanwhile, when the first time information is acquired by continuously driving the GPS receiving unit 300, there is a problem in that power consumed in driving the GPS receiving unit 300 increases.

In order to solve these problems at the same time, for example, the control unit 400 controls driving of the GPS receiver 300 to be OFF when the obtained electrical energy is equal to or greater than a predetermined energy value so that the first time information is not obtained. , When the electrical energy obtained is less than a predetermined energy value, the driving of the GPS receiver 300 may be controlled from OFF to ON to obtain the first time information.

Here, the control unit 400 controls the operation of the GPS receiver 300 to be OFF when the obtained electrical energy is equal to or greater than a preset energy value (when it is determined that it is daytime), and furthermore controls the operation of the GPS receiver 300 to be OFF, and furthermore, from the timer unit for the second time. You don't even get information.

As a result, power consumed when the control unit 400 obtains the second time information can also be saved.

On the other hand, when the electrical energy obtained is less than the preset energy value (when it is determined that it is night), the control unit 400 first senses the timer unit before controlling the operation of the GPS receiver 300 from OFF to ON. Thus, the second time information may be obtained from the timer unit.

At this time, the controller 400 may selectively control driving of the GPS receiver 300 from OFF to ON according to whether the second time information has reached a predetermined time.

To explain this in more detail, assuming that the predetermined time is 6:00 PM, the control unit 400 first senses the timer unit when the obtained electrical energy is less than the preset energy value, and then detects the second timer unit from the timer unit. Time information may be acquired, and when the obtained second time information is 5:50 pm, the driving of the GPS receiver 300 is kept OFF, and when the obtained second time information is 6:10 pm Driving of the GPS receiver 300 may be controlled from OFF to ON.

Here, when the GPS receiver 300 is controlled from OFF to ON by the control unit 400, the GPS receiver 300 may obtain the first time information, and the control unit 400 may acquire the obtained An error in the second time information may be eliminated by resetting and substituting the first time information into the timer unit.

Thereafter, the GPS receiver 300 is driven in an ON state for a predetermined time (eg, 10 minutes) to obtain the first time information, and after the predetermined time has elapsed, the control unit 400 It can be controlled from ON to OFF again by the control of .

As a result, power consumption by driving the GPS receiver 300 can be minimized.
