Description

Self-generation-based road sign and control method thereof

The present invention relates to the use of a system capable of self-generating electric power that can be applied in various areas such as street lights, traffic lights on intersections, tunnel self-power, and bridges by using self-generation. Also illustratively, the present invention relates to a method, apparatus and system for controlling a road sign using self-generation. More particularly, it relates to a method, apparatus, and system for controlling the light emission of a plurality of road signs using electric power obtained by self-generation.

In recent years, in the face of global energy depletion, various methods and devices for effective energy conservation during the development of new alternative energy and energy circulation are being actively developed.

Accordingly, interest in energy harvesting technology that realizes energy recycling as an alternative energy source is increasing. As such, there is a demand for an energy recycling system using such a vehicle.

In detail, the vibration force and pressure according to the operation of the vehicle are considerably supplied to the road on which the vehicle travels, and if the energy consumed in the operation of the vehicle is considered, the vibration force and pressure applied to the road provide considerable energy. However, since such energy cannot be utilized and is wasted as it is, various technologies have been developed to recycle the vibration and/or pressure energy.

On the other hand, in general, the driving direction of the road is indicated on roads, tunnels, underpasses, foggy roads, sidewalk boundaries, median zones, etc., or dangerous areas such as traffic accidents or construction are displayed in dangerous areas such as traffic accidents or construction even at night. Safety guidance lights (road signs) are installed to prevent accidents by notifying them easily.

These safety guidance lights are generally configured in a form that allows a driver to identify a lane by using a reflector or a light-emitting body such as a light-emitting diode (LED).

In detail, the safety guidance lamp is divided into a reflective type and a light emitting type according to the driving method, and the light emitting type is further subdivided into a flashing type, a lighting type, and a switching type.

Here, the light-emitting type safety guidance lamp has a built-in light source such as an LED and emits light by itself, thereby effectively transmitting a light-emitting signal to a driver or pedestrian. However, since a separate power supply is required due to the characteristics of the LED, power consumption by these facilities installed on the road is considerable.

Accordingly, there is a growing need to seek and implement a method for minimizing the power consumed in such a safety induction lamp.

In addition, since these safety guidance lights are not freely adjustable in day/night brightness with a brightness of a generally constant size, when the night brightness of the safety guidance lights is the same as during the daytime, the driver's sudden brightness causes a problem in securing the driver's field of vision.

In addition, the existing safety guidance lights do not have an automatic on/off function when fog is generated in a fog risk area, so the manager has to check whether fog is generated directly and operate the safety guidance lamps.

In addition, conventional safety guidance lights are generally installed innumerable on the road and controlled by a collective control, so that unnecessary power is consumed or it is difficult to perform a flexible operation according to the situation, so a solution is required.

In addition, since it may be difficult to operate the safety induction lamp in the event of an unexpected situation such as insufficient power supply, it is necessary to introduce a new technology for the safety guidance lamp that can cope with the emergency situation on its own without a separate power supply. am.

<Method of controlling road signs using self-generation>

Hereinafter, with reference to the drawings, a method of controlling the road sign 200 using self-generation based on the self-generation device 100 and the plurality of road sign 200 will be described in detail.

6 is a flowchart illustrating a method and system for controlling a road sign 200 using self-generation according to an embodiment of the present invention.

Referring to FIG. 6 , first, the self-generation device 100 may generate and store electrical energy (power). (S101)

In detail, the self-generation device 100 may be implemented to be embedded in the road surface in the width direction of the road on which the vehicle moves, and the power generation device accommodating part 124 in the form of a space may be formed therein. And the self-generation device 100 accommodates the lower body 102 including the power generation unit installation space 107 in the power generation device accommodating unit 124 , and the power generation unit 104 disposed on the accommodated lower body 102 . ) through self-generation.

At this time, the power generation unit 104, when the lifting cover 103 of the self-generation device 100 lifts and lowers, reacts with the cam 109 to give a rotational force and generate and store electricity by the rotational force. can

In this way, the self-generation device 100 responds to the movement of the vehicle and enables the generation and storage of electricity, and road facilities using electricity such as the road sign 200 can be used using the generated electricity. By doing so, it is possible to save energy resources, minimize power consumption, and further contribute to economic development.

Meanwhile, the environment sensor 300 may acquire surrounding environment information, which is information related to the environmental condition of a road site. (S103)

In detail, the environment sensor 300 includes temperature, humidity, illuminance, rain, and snow detected in the road environment by using a temperature sensor, a humidity sensor, an illuminance sensor, a rain sensor, a snow volume measurement sensor and/or a vehicle detection sensor. It is possible to sense surrounding environment information including the amount of the sky and vehicle condition information.

In addition, the environment sensor 300 may transmit the sensed surrounding environment information to the integrated management server 400 and the like.

That is, the environmental sensor 300 senses and provides environmental information around the road, taking into account environmental conditions such as temperature, humidity, illuminance, rain, snow, and/or vehicle conditions of the road. It can assist in controlling the light emission.

Next, the integrated management server 400 may receive the surrounding environment information from the environment detection sensor 300 , and may generate a brightness control signal according to the received surrounding environment information. (S105)

Here, the brightness control signal is a signal for determining the brightness level of light output through the light emitting unit of the road sign 200 , and whether fog occurs or not, which is determined based on the surrounding environment information obtained from the environment detection sensor 300 , daytime / It may be generated based on whether it is at night, rainfall information, snowy weather information, and/or vehicle situation information.

In this case, the brightness control signal may include an on/off control signal and/or brightness control information (eg, intensity of brightness, light emission color information, etc.) for the light emitting unit of the road sign 200 .

In detail, in an embodiment, the integrated management server 400 may determine whether fog is generated based on temperature and humidity information received from a temperature sensor and a humidity sensor of the environment detection sensor.

For example, the integrated management server 400 may detect a fog generation state when the temperature and humidity values detected by the temperature sensor and the humidity sensor are temperature and humidity values within a predetermined fog generation condition range.

In this case, when it is determined that fog has occurred, the integrated management server 400 may set the on/off control signal of the brightness control signal as an on control signal. Conversely, when it is determined that fog does not occur, the integrated management server 400 may set the on/off control signal of the brightness control signal as an off control signal.

Thus, the integrated management server 400 may generate a brightness control signal to perform a light emitting operation by supplying power to the light emitting unit of the road sign 200 when an on control signal is set depending on whether fog occurs, and an off control signal When is set, a brightness control signal may be generated so that the light emitting unit of the road sign 200 does not operate.

For example, the integrated management server 400 may set the on/off control signal of the brightness control signal as the on control signal when it is determined that it is raining based on the rain information detected by the rain sensor. Conversely, when it is determined that it is not raining, the integrated management server 400 may set the on/off control signal of the brightness control signal as the off control signal. That is, the integrated management server 400 may generate a brightness control signal to perform a light emitting operation by supplying power to the light emitting unit of the road sign 200 when an on control signal is set according to whether or not precipitation, and an off control signal When is set, a brightness control signal may be generated so that the light emitting unit of the road sign 200 does not operate.

Thus, the integrated management server 400 adjusts the brightness of the road sign 200 according to the amount of rain or snow falling on the road so that the road surface reflects the light emitted from an external light source (eg, a vehicle headlight or street lamp). By doing so, it is possible to implement an appropriate response in a situation where the lane is not visible.

Also, the integrated management server 400 may determine whether it is day/night based on the illuminance information received from the illuminance sensor of the environment detection sensor.

For example, the integrated management server 400 may detect a case in which the illuminance value detected by the illuminance sensor is greater than a preset reference illuminance value during the day, and conversely detects a case where the illuminance value is smaller than the preset reference illuminance value at night. can do.

In this case, the integrated management server 400 may set the on/off control signal of the brightness control signal as the off control signal when it is determined that it is daytime (daytime) based on the illuminance information. Conversely, the integrated management server 400 may set the on/off control signal of the brightness control signal as the on control signal when it is determined that it is night (night).

That is, the integrated management server 400 may generate a brightness control signal to perform a light emitting operation by supplying power to the light emitting unit of the road sign 200 when the on control signal is set depending on whether day/night, and off When the control signal is set, the brightness control signal may be generated so that the light emitting unit of the road sign 200 does not operate.

Thus, the integrated management server 400 operates the light emitting part of the road sign 200 when it is determined that it is night to provide a safety guidance signal to the driver and/or pedestrian, and when it is determined that it is daytime, the unnecessary road sign ( 200), it is possible to limit the light emitting operation to perform the operation of the light emitting unit suitable for the surrounding situation.

Meanwhile, the integrated management server 400 may generate brightness adjustment information based on the illuminance information received from the illuminance sensor of the environment detection sensor when the on-control signal is set based on the surrounding environment information.

In detail, the integrated management server 400 generates brightness control information for controlling the intensity (brightness intensity) and/or color of the light emitted by the light emitting unit of the road sign 200 that performs the light emitting operation based on the illuminance information. can

For example, the integrated management server 400 may set a brightness intensity that decreases as the illuminance value increases in inverse proportion to the illuminance value detected by the illuminance sensor. Also, the integrated management server 400 may determine the emission color according to the matching color for each preset illuminance value based on the illuminance value detected by the illuminance sensor.

In addition, the integrated management server 400 may generate brightness control information by reflecting the determined brightness intensity and/or emission color.

In this way, the integrated management server 400 controls the on/off control of the light emission of the road sign 200 as well as the intensity and color of the light emitted based on the surrounding environment information, so that the road more optimized for the road situation. Light emission control of the label 200 may be implemented.

Meanwhile, the integrated management server 400 may generate a brightness control signal based on vehicle situation information received from the vehicle detection sensor of the environment detection sensor.

That is, the integrated management server 400 may generate an on/off control signal and/or brightness adjustment information of the road sign 200 based on vehicle presence information, direction information, and/or speed information.
