The timer 152 is configured to supply a lighting signal and a current to the LED of the display panel 140 at a set time.

The battery device 151 is charged by the solar panel 170 for collecting solar light, the wind turbine 180 for generating wind energy, and the geothermal rod 190 for collecting geothermal energy by embedding in the ground. Therefore, it has three charging paths as follows.

First, there is a solar energy charging path (SC) in which the solar light collected from the solar panel is converted into electrical energy through the solar controller (SC1), and secondly, the mechanical energy formed from the wind turbine 180 is converted into electrical energy. A generator WC1 for converting to a DC, an AC / DC converter WC2 for converting an AC current generated by the generator WC1 to a DC current, and a DC current converted by the AC / DC converter WC2. There is a wind energy charging path (WC) that is charged through a constant voltage control circuit (WC3) to maintain a constant voltage, and thirdly, a heater pump (GC1) that collects geothermal heat from the geothermal rod 190 and converts thermal energy into electrical energy ), An AC / DC converter GC2 for converting the AC current generated by the heater pump GC1 into a DC current, and a DC voltage converted by the AC / DC converter GC2 to maintain a constant voltage.

The RGB color control unit 162 for adjusting the RGB color is applied to the technology for the main pipe widely used in the art, the method for adjusting the RGB color control unit 162 by the wireless device also applies the technology for the main pipe. Detailed description thereof will be omitted.

In addition, the illumination sensor 163 is configured to send a signal to turn on the LED to the timer 152 on a cloudy day, even in daylight, and when the illumination is increased again by the sun, the LED off signal to the timer 152. To send.

The battery device 151 includes a battery 151a that is charged with a current, a battery voltage checker 151b that checks a voltage of the battery 151a, and a BMS board that manages a state of the battery 151a. Board) 151c.

That is, the battery voltage checker 153 checks the voltage of the battery 151a and transmits a power cutoff signal to the timer 152 when the voltage of the battery 151a is insufficient even at night, thereby causing the LED of the display panel 140 to blink. do.

In addition, the BMS board 151c is a circuit that manages the state of the battery 151a and functions to control charging and discharging according to the voltage of the battery 151a.

That is, the input or output of current to the battery 151a is controlled by the battery management system board 154.

Circuit configurations and devices that compare current amounts relative to charge paths apply the conventional technique of current amount comparison.

In the battery voltage check, when the battery voltage reaches the discharge limit at night, the primary voltage is cut off by the BMS board 151c, but the battery 151a is again turned off by the wind when the load is cut off. It will be charged. At this time, when the voltage is again charged by the wind, the LED is turned on again, but the battery 151a does not hold enough power, and then turns off again after a while.

To prevent this, when the battery voltage reaches the discharge limit at night, the LED is not turned on at night or the LED is turned on again after a specified time or capacity is charged.

Solar energy charging path (SC), wind energy charging path (WC), geothermal energy charging path (GC) can be implemented by applying the conventional technology with the above-described configuration.

The solar controller SC1 converts sunlight collected from the sun during the day into electrical energy by charging a constant voltage controller built-in PWM method and charges the battery 151a.

4 is another embodiment of the present invention road display device.

As shown in FIG. 4, a road display device according to another embodiment includes a pair of solar panels 170, which are configured to be mounted on the upper pillar 130 at an altitude and a direction (azimuth angle) of the sun. It is characterized in that it is configured to rotate independently.

Figure 5 is a partially enlarged schematic view showing a rotational driving state of the solar panel according to another embodiment of the present invention road display device.

As shown in FIG. 5, the pair of solar panels 170 are rotated toward the solar panel 170 in which a small amount of solar panels 170 are collected by comparing the amount of solar energy that is collected. Configured.

That is, by comparing the amount of solar energy collected in a pair of solar panels 170 for a predetermined time to each other, the amount of solar energy collected in a solar panel 170 at any one of the solar panels 170 at the other side When the solar panel is less concentrated by 15% than the amount of solar energy collected, the solar panel 170 collected less is rotated about the upper pillar 130 on the upper pillar 130. Will be done.
In other words, in the initial state shown in FIG. 5, when the amount of solar energy collected in a pair of solar panels 170 is different from each other by 15% or more, the solar panels 170 that are collected less are collected more. Rotate to the panel 170, by a predetermined angle. After 30 minutes, the comparison is made again. In this case, when a pair of solar panels rotates along the sun and reaches an angle in the same direction toward the sun, compared to the 30-minute intervals, the pair of solar panels eventually have a similar amount of heat collection within 15%. The difference of more than 15% will not come out of course. Therefore, the solar panels are no longer moved by relative comparison and do not overlap each other. The initial position of the pair of solar panels 170 is initialized at the time of sunset every day as the main common technique in the solar solar panel technology, and becomes the position of FIG. 5. Of course, the initial position of the pair of solar panels 170 can be arbitrarily changed as necessary.

6 is a schematic view of a driving unit for rotating the solar panel according to another embodiment of the present invention road display device.

Therefore, when the rotor 172 rotates about the upper pillar 130 along the azimuth of the sun, the natural solar panel 170 is also rotated.

In the present invention, in order to drive the pair of solar panels 170 individually, one solar panel 170 is configured on one rotating body 172, and each rotating body 172 has a gear tooth (inside). The gear tooth is rotated in engagement with the gear 173 formed inside the rotating body 172. The gear 173 has a central portion of the gear 173 by a motor (not shown). It is coupled with the rotating shaft 175 to transmit the rotational driving force.

The bearing device 176 is configured between the respective rotating bodies 172 and the upper column 130 for smooth rotation driving and engagement.

The solar panel 170 is driven along the altitude of the sun to track the position of the sun. Can be implemented by conventional techniques.

Since the power used for the rotation of the solar panel 170 also uses a power source integrated by solar energy, if it is controlled to rotate in less than 15%, it may cause energy waste due to too frequent rotational driving.

The comparison time is preferably compared with the amount of solar energy collected in the solar panel 170 at 30-minute intervals, and if the comparison time interval is too narrow, the solar panel 170 is often driven in a temporary phenomenon, rather than wasting energy It may cause.

The comparison time interval adjustment and comparison amount measurement of the solar panel 170 and the rotational drive of the solar panel 170 can be controlled by the controller 160.

As described above, the road guidance display device using the renewable energy of the present invention makes it easy to know the road information even at night by the LED, and by controlling the single color or the three-color LED freely, the appearance is very excellent, and also with the sun. The use of wind and geothermal energy sources has significant effects, such as being very environmentally friendly.
