Hereinafter, preferred embodiments of a road alarm system and a control method thereof according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram showing a road warning system according to the present invention.

Referring to FIG. 1, the road alarm system according to the present invention includes at least one section detection member 300 for detecting the presence of mist, rockfall, and an accident, and one or more section detection members 300 An integrated server 100 for controlling the section sensing member 300 to transmit and display related information to the section sensing member 300 for monitoring the road in the traveling direction when the road anomaly detection signal is received, And an information server 200 for transmitting the information to the integration server 100.

When the road anomaly detection signal of the section detection member 300 for monitoring the abnormality of one or more sections set on the road is received, the integration server 100 transmits the information to the relevant agency (police station road patrol or road management construction) . In addition, the integration server 100 may determine whether there is an abnormality in a corresponding section (for example, an accident of a car, a fallout, or the like) to an other section sensing member 300 that senses a road running to the section sensing member 300, , Fog generation, strong wind, heavy rain). In addition, the integration server 100 transmits weather information of the weather server 200 to each of the section sensing members 300 so that it can be informed to drivers of the vehicles traveling in the corresponding section.

The information server 200 receives news bulletins of weather information, politics, economy, defense, culture, sports, and technology from related institutions (for example, a media server, an Internet portal website, 100, and the integration server can transmit the information received from the information server 200 through each of the section sensing members 300. [

The section sensing member 300 is installed for each section of the road in which the driver's view is limited, such as at least one section of the entire section of the road, particularly, a section where mist generation or strong wind is frequently generated and / or a curve section.

When one or more of the road accident, fog, heavy rain, strong wind, and rockfall is detected, the section detecting member 300 transmits information to the integration server 100, And a voice signal to sequentially change and decelerate and / or stop the lane so that the driver is alerted sequentially to the abnormality.

More preferably, the section sensing member 300 outputs a warning sound to lower the speed of the traveling vehicle to a predetermined speed or less to guide the drivers of the traveling vehicle to decelerate the vehicle.

That is, the section detecting member 300 of the present invention outputs an abnormal situation of the preceding road as a character, alerts the driver of the running speed of the vehicle to output a warning sound to operate the deceleration, And outputs a light emission signal through the road surface to the automobile whose speed is reduced by the first warning in the set interval between the accident occurrence period and the second occurrence warning by outputting the light emission signal to change, stop, and / or slow down the lane.

The detailed structure of such a section sensing member will be described in detail with reference to FIG.

FIG. 2 is a block diagram showing a section detecting member in the road alarm system according to the present invention, and FIG. 3 is a view showing an example of the operation of the road alarm system according to the present invention.

2 and 3, the section sensing member 300 according to the present invention includes a control unit 310, a power generation unit 320 for generating power by sunlight and wind power, A communication unit 350 for communicating with the integration server 100; a storage unit 340 for storing the photographed image and road anomaly information; and a control unit 340 for determining whether the guard rail 500 is damaged An interval detection unit 370 for detecting presence / absence of a vehicle and a speed and a road anomaly according to a predetermined interval, a camera unit 380 for capturing an image of the road, And an alarm unit 390 for alarming as a light emitting signal.

The power generation section 320 includes a solar power generation means 321 for producing a power source by sunlight and a wind power generation means 322 for producing a power source by wind power. It is also possible that the present invention receives power from the grid of the utility company in addition to the electric energy produced by the solar power generator 321 and the wind power generator 322.

The charging unit 330 is charged with the power supplied from the power generation unit 320 and / or the system and supplies power. The charger 330 may be equipped with a mass storage energy storage system.

The power generation unit 320 and the charging unit 330 are generally known in the art and will not be described in detail.

The communication unit 350 may transmit the abnormality detection signal and / or image information of the road to the integrated server 100 located at a remote place by the wired / wireless Internet or the power communication system, or may transmit weather information, And receives road anomaly information of the other section monitoring member of the section.

The storage unit 340 stores the images photographed by the camera unit 380 and the anomaly information detected by the section detection unit 370 and the guardrail detection unit. In addition, the storage unit 340 stores weather information received from the integration server 100, news breaking information, and abnormal information of the interval sensing member 300.

The section detecting unit 370 includes an interval detecting unit 371 for detecting the presence and speed of the vehicle in the set interval, an image detecting unit 392 for detecting the presence or absence of an accident, a pedestrian, And environmental sensing means 373 for sensing environmental information such as strong wind, fog and heavy rain.

The section detecting means 371 senses the presence and speed of the vehicle running on the road and applies the sensed speed to the control unit 310. To be more specific, the section detecting means 371 preferably applies a loop sensor embedded in the road surface so as to output an electrical signal by the load of the vehicle.

The loop sensor generally has one or more loop coils wound on the outer surface of the core body, and when a load is applied to the loop coil, the loop sensor senses a change in the inductance and outputs an electrical signal. The structure of such a loop sensor has been briefly described as it is generally known.

Accordingly, one or more of the section detecting means 371 are spaced apart from each other by a predetermined distance and are buried on the road surface, and sequentially transmit the vehicle detecting signal by the load when the vehicle is running.

For example, the section detecting means 371 is spaced apart from each other in the first section A and the second section B, which are ahead of the curve section C in which the visibility of the running direction is restricted or the section C in which the mist is generated Several are installed. Therefore, if the vehicle stopped immediately after the curve section C is stopped at the position where the section detecting means 371 is buried, the section detecting means 371 detects the vehicle detection signal for a longer period of time It is transmitted continuously.

Also, the section detecting means 391a, 391b, 391c before the position of the stopped vehicle senses the vehicle being driven and transmits a vehicle detection signal to the control portion 310. [ At this time, as the vehicle detection signal is outputted for a shorter time, it can be confirmed that the vehicle is stopped or running through the time interval of the signal received by the control unit 310. [

Therefore, when the vehicle detection signal received in the curve section C is received and the vehicle running in the rear position A or B is detected, the control section 310 controls the alarm section 390 to travel in the curve section And alerts the rear vehicles to the presence or absence of the vehicle stopped ahead.

Here, when at least one vehicle sensing signal is received by the section sensing means 371, the control unit 310 determines whether the next vehicle sensing signal is received from the interval between the interval sensing means 371 and the time when the initial vehicle sensing signal is received The traveling speed of the vehicle can be calculated.

Alternatively, the present invention may detect the presence or absence of a vehicle using a laser and the traveling speed as another embodiment. This applies to a speed camera which is generally applied, and can be applied when there are many vehicles running on the road. At this time, the control unit 310 can check the speed of the vehicle received from the speed camera and sequentially control the alarm unit 390 to alert.

The image sensing means 392 is used as an infrared image camera capable of nightly surveillance to detect whether there is an abnormality in the road, and transmits the detected abnormality to the control unit 310. For example, the image sensing means 392 sets a reference image, and when an object included in the previous captured image in the image captured in real time is included in the current captured image and is determined as an object not included in the reference image And transmits an abnormality detection signal to the control unit 310.

Here, the reference image is set to include only the fixed object in the corresponding road section. Therefore, when the vehicle is stopped due to a failure or an accident, the image sensing means 392 continuously captures the stopped vehicle among several images continuously captured. Then, the image sensing unit 392 compares the reference image with the most recently captured image and transmits an anomaly detection signal if there is an object (a stationary automobile) that is commonly photographed in the reference image and the image continuously shot for a predetermined time .

The environment sensing means 373 includes at least one sensor for sensing the fog, the wind speed, and the amount of rainfall within the set interval. The environment detecting means 373 is generally known in the art and its description will be omitted.

The camera unit 380 photographs, for example, an image of a road set as CCTV in real time. The control unit 310 stores the image captured by the camera unit 380 in the storage unit 340 and transmits the image in real time or in response to a request from the integration server 100. [

The alarm unit 390 includes an information display unit 391 that is spaced apart from one another by a predetermined distance and outputs text or image information under the control of the control unit 310, a road surface light emitting unit 392 that emits light buried in the road surface, And audio output means 393 for outputting an alarm sound.

The information display means 391 may include at least one information display means 391 for alarming a road abnormality as a character at a position ahead of a corresponding section where mist, heavy rain, falling rock, strong wind and / or an accident occurred, , News bulletin, and the like.

For example, the information display means 391 is an electric sign board capable of outputting characters and images. In the previous sections A and B of a section where the fog is generated or curved roads in which the driver's field of view is restricted, Weather information such as the presence of an accident in the road, falling rock, strong wind or heavy rainfall.

The road surface light emitting means 392 warns the driver of road anomalies as one or more of the roads buried in the road and in various colors immediately before a fog-generated section, a curve road, or an accident occurrence section. For example, under the control of the control unit 310, the road surface light emitting means 392 flashes in red if a vehicle or a rockfall has been stopped in the running direction on a single-lane one way road. If the vehicle is in a weather condition such as fog or heavy rain, Or yellow light.

The sound output means 393 outputs an alarm sound as a voice signal. For example, the voice output means 393 can output an alarm message or output a siren to a person's voice to concentrate the attention of the driver. Here, the information display means 391 and the voice output means 393 preferably output a warning message with characters and voice, and the alarm message preferably includes a message to decelerate the traveling speed of the vehicle to a set speed.

The control unit 310 receives the section detection signal, the image detection signal, and the environment detection signal transmitted from the section detecting unit 371, the image detecting unit 392, and the environment detecting unit 373, Controls the information display means 391, the audio output means 393 and the alarm unit 390 in order to sequentially alarm the vehicles traveling to the abnormal point.

That is, the control unit 310 sets a predetermined distance, which is a further distance from the accident occurrence point where the abnormality is detected from the section detection unit 370, to the rear section as the first section A, (B).

When the vehicle is sensed by the first section sensing means 371a installed in the first section A of the farthest position and the vehicle sensing signal of the first section sensing means 371a is received, The traveling speed of the vehicle is calculated through the time and distance until the vehicle detection signal of the second section sensing means 371b is applied. Thereafter, the control unit 310 controls the information display unit 391a (for example, the first electric signboard) of the first section and the sound output unit 393 to alert the roads to characters and alarms, To induce deceleration.

The control unit 310 also receives the vehicle sensing signal from the third zone sensing unit 371c installed in the second zone B and displays the information display unit 391b installed in the second zone B (For example, lane change, stop, slow travel guide), and outputs a second warning as road surface light emission means 392 buried in the road surface by controlling the distance .

That is, the present invention warns that the speed of the vehicle is primarily decelerated through the plurality of information display means 391a, 391b and the sound output means 393, and then the second section B close to the point of occurrence of the accident, So as to prevent an accident in the fog occurrence period or the curve section C where the driver's view is limited by guiding the stop or slow running operation through the road surface light emitting means 392 embedded in the road surface and the information display means 391 do.

Also, the present invention can detect collision from a slope around the road through the guard rail sensing unit 360, or whether the guard rail 500 of the traveling vehicle collides or the guard rail 500 is damaged.

The guard rail sensing unit 360 will be described with reference to FIGS. 4 and 5. FIG.

FIG. 4 is a block diagram illustrating a guardrail detection unit of a road alarm system according to the present invention. FIG. 5 is a plan view illustrating an installation structure of a guardrail sensing unit in the road alarm system according to the present invention.

4 and 5, the guard rail sensing unit 360 of the present invention senses an impact applied to the guard rail 500 installed on the road in order to prevent boundary display of the road and departure of the vehicle, . The guardrail sensing unit 360 includes at least one loop sensor 363 installed on each guard plate 510 of the guard rail 500 and signal conversion means 361 for converting the sensing signal of the loop sensor 363 And a guard communication means 362 for transmitting the signal converted by the signal conversion means 361 to the control unit 310. [

The loop sensor 363 includes at least one loop coil 363b wound on the outer surface of the center body 363c, a sheath 363a for protecting the loop coil 363b and an elastic material 363d made of an elastic material at the outer surface of the sheath ). The loop sensor 363b also includes inductance sensing means (not shown) for sensing a change in inductance of the loop coil 363b and outputting a signal, though it is not shown in the figure.

It is preferable that the roof sensor 363 of the present invention is installed on a guard rail 500 that separates the front plate 510a and the rear plate 510b from each other to form one guard plate 510. [

More specifically, the guard plate 510 of the guard rail 500 includes a front plate 510a and a rear plate 510b spaced apart from each other, an elastic supporter 530 elastically supporting between the front plate 510a and the back plate 510b, And a support rod 520 for supporting the front plate 510a and the back plate 510b upright on the ground.

The double elastic support 530 is composed of a first elastic plate 531 and a second elastic plate 532 having side portions 531b and 532b extending to both sides from horizontally extending central portions 531a and 532a. Although the illustrated bar is shown in the form of a bar as a plane, actually an upright plate is applied.

The first elastic plate 531 is fixed to the rear plate 510b by being closely attached to the first elastic plate 531 and the second elastic plate 532 is extended horizontally Side portions 532b extending in the both side directions from the extended central portion 532a are tightly fixed to the front plate 510a. The first elastic plate 531 and the second elastic plate 532 are formed so that the horizontally formed central portions 531a and 532a are in close contact with each other and the side portions 531b and 532b are extended so as to be inclined in opposite directions, Spaced apart from each other.

At this time, the loop sensor 363 is fixed in the spaced space between the first elastic plate 531 and the side portions 531b and 532b of the second elastic plate 532. When the impact is applied to the front plate 510a or the rear plate 510b of the guard rail 500 due to the collision of a vehicle falling on a slope falling on the peripheral slope or a running road, And the side portions 531b and 532b of the second elastic plate 532 are rotated.

The loop sensor 363 of the present invention is constructed in a double structure as an elastic material (for example, a rubber tube) in addition to the outer shell so that the first elastic plate 531 and the side portions 531b and 532b of the second elastic plate 532 Even if pressed, it is not broken.

The loop sensor 363 outputs a sensing signal when the pressure applied by the first elastic plate 531 and the side portions 531b and 532b of the second elastic plate 532 is applied. Therefore, the signal converting means 361 converts and amplifies the detection signal output from the loop sensor 363 and outputs it to the guard communication means 362. [

The control unit 310 receives the abnormality detection signal received from the guard communication unit 362 and detects the damage of the guard rail 500 and transmits the related information to the integration server 100. At the same time, 390) to alarm the occurrence of a fall or an accident on the road,

The present invention includes the above-described configuration, and a control method of the road alarm system according to the present invention will be described below with reference to FIGS. 6 to 9. FIG.

FIG. 6 is a flowchart showing a control method of the road alarm system according to the present invention.

Referring to FIG. 6, the control method of a road alarm system according to the present invention includes a road monitoring step S100 for monitoring an environment such as a fall of a road, an accident, mist, or heavy rainfall, (A), which is located at a remote location from the point of occurrence of an accident, when the abnormal situation occurs on the road in the fault occurrence determination step (S200) And a secondary section warning step S400 in which when the traveling vehicle enters the second section B after the first section warning step S300 and the second section B, the second section warning step S400 is included.

The road monitoring step S100 is a step in which the control unit 310 receives environmental information such as fog, heavy rain, and strong wind from the section detecting unit 370 and the guard rail detecting unit 360, . The road monitoring step S100 will be described later with reference to Fig.

In the abnormality occurrence determination step S200, the controller 310 checks the detection signals of the section detection unit 370 and the guardrail detection unit 360 to determine whether an abnormal condition of the road has occurred.

In the primary section warning step S300, the alarm section 390 installed in the first section A located at a long distance is controlled in the abnormality occurrence determination step S200 to firstly warn that there is an abnormality in the road in the traveling direction . Here, the primary section warning step (S300) outputs a voice warning sound to induce a deceleration of the traveling speed of the vehicle in the first section (A). The primary section warning step S300 will be described with reference to FIG.

In the secondary section warning step S400, warning and guidance are given during the lane changing, stopping, and slowing of the driving vehicle as character and road surface light emission at a position near the point where the abnormality occurs after the primary section warning step S300 . A more detailed description will be given later with reference to Fig.

FIG. 7 is a flowchart showing the road monitoring step in the control method of the road alarm system according to the present invention.

7, the road monitoring step S100 includes an environmental sensing signal receiving step S110 for receiving an environmental sensing signal for detecting whether a mist or a strong wind is blown, an image sensing step S120 for receiving a video signal of a predetermined interval, (S130) for judging whether the road is abnormal, a guardrail judgment step (S140) for judging the abnormality of the guard rail (500), an abnormality judgment step And an alarm control step S150 in which the integration server 100 issues a road abnormality signal and an alarm when an abnormality occurs in the step S130 or the guardrail determination step S140.

The environmental sensing signal reception step S110 is a step in which the control unit 310 receives the environmental sensing signal including the fog, the wind speed, and the rainfall amount from the environment sensing unit 373. The environment sensing means 373 senses at least one of a mist, a rainfall, and a wind speed, and transmits it to the control unit 310.

The image capturing step S120 is a step in which the image sensing unit 392 continuously captures an image by infrared ray imaging and transmits an abnormal situation to the control unit 310. [ Here, in the image capturing step S120, the image sensing unit senses the abnormality of the road by infrared image sensing, and the camera unit 380 photographs the actual image of the road. The real-time image photographed by the camera unit 380 is transmitted to the integration server 100 under the control of the control unit 310.

The abnormality determination step S130 is a step in which the control unit 310 receives the environment sensing and image sensing signals received from the environment sensing unit 373 and the image sensing unit 392 to determine the road and environment abnormality. The control unit 310 determines whether fog occurs and whether wind speeds above the rainfall or reference values are detected from the environment detection signal received from the environment detection unit 373. [

If there is an object included in the previous image and the current image consecutively photographed from the image sensing means 392 (for example, a vehicle on the road, a guard rail 500, a rockfall) , And receives an abnormality detection signal according to the presence or absence of an accident vehicle, a fallout, or a pedestrian on the road compared with the reference image.

The guardrail determination step S140 is a step of determining whether the control unit 310 receives an abnormal signal of the guardrail sensing unit 360. [ Here, the guardrail sensing unit 360 may be configured to detect an external impact (for example, a guard of a vehicle), a front plate 510a of the guard plate 510, and an elastic support 530 that elastically supports the back plate 510b. The first elastic plate 531 and the side portions 531b and 532b of the second elastic plate 532 are rotated to press the loop sensor 363 by the collision of the rail 500 and the rock falling from the road slope. Therefore, the loop sensor 363 outputs an electrical signal as the inductance of the coil 363b wound by the pressing of the elastic plates 531 and 532 is changed. Therefore, the guard communication means 362 transmits the converted and amplified signal through the signal converting means 361 to the control unit 310. [ Accordingly, the controller 310 can check whether the guard rail 500 is abnormal.

Here, the abnormality determination step S130 and the guardrail determination step S140 are not performed in the order described in the drawings, but may proceed simultaneously or in opposite order. The above-described examples are not intended to limit the present invention.

In the alarm control step S150, when the control unit 310 determines that a stoppage and / or an accident has occurred in the fault determination step S130 due to fog, strong wind, heavy rain, or a curve section C, , It is determined that there is an abnormality in the guard rail 500, the road abnormality signal is transmitted to the integration server 100 and an alarm is issued. Here, the section detecting member 300 divides the period covered by each of the sections into a first section A and a second section B, and performs the above-mentioned first section warning step S300 and the second section warning step S400 do.

In addition to the section detecting member 300 that senses the road abnormality, the other section detecting member 300 can detect weather information received from the integrated server 100, news breaking news, and / or road abnormality information of the other section sensing member 300 Receives from the integration server 100 and alerts the driving vehicle in the charge section.

In other words, when an abnormal signal is received from the plurality of section detection units 370, the integration server 100 detects the occurrence of fog, heavy rain, and strong wind in the section of the direction of travel to the other section detection unit, And whether or not an accident has occurred.

8 is a flowchart showing a primary section warning in the control method of the road alarm system according to the present invention.

Referring to FIG. 8, in the primary section warning step (S300), in the above-described road monitoring step (S100), the section sensing member 300 determines whether or not the road is abnormal in its own section (fog, heavy rain, strong wind, Is detected, it is alarmed to decelerate the speed of the traveling vehicle in the section divided from the accident point of the own zone to the first section. More specifically, the primary section warning step may include a vehicle sensing step S310 in which the control unit 310 senses a traveling vehicle from the section sensing unit 370 of the first section A, a vehicle sensing step S310, An alarm output step S320 for displaying a warning sound and a character when the vehicle is detected, a setting speed determination step S330 for determining whether the vehicle speed is equal to or lower than a predetermined speed after the alarm outputting step S320, And turning off the warning sound when the speed of the vehicle is lower than the set speed in the determining step S330 (S340).

The vehicle sensing step S310 is a step in which the control unit 310 receives the vehicle sensing signal from the first section sensing unit 371 installed in the first section A. The first section detecting means 371a is a loop sensor embedded in the road surface and outputs electrical signals by the load of the vehicle. Accordingly, the control unit 310 receives the vehicle detection signal from the first section detection unit 371a.

In the first alarm output step S320, the controller 310 calculates the vehicle speed as the distance from the vehicle detection signal of the second section sensing means 371b in the first section sensing means 371a, A heavy rain, a strong wind, an accident, and / or a fallout. Here, the control unit 310 controls the information display means 391 to display the speed of the current driving vehicle together with the road anomaly information, and to output a message to decelerate the vehicle at the set speed.

The control unit 310 also controls the voice output unit 393 to control the voice output unit 393 to output a warning sound together with a message for calculating the speed of the traveling vehicle and inducing deceleration of the vehicle running at a speed higher than the set speed .

That is, the control unit 310 outputs a character and a voice signal to the vehicle that is driving to the corresponding point where the abnormality of the road occurs in the primary section warning step (S300) so as to decelerate the speed together with the abnormality of the road.

The setting speed determination step S330 is a step of determining whether the traveling speed of the vehicle is equal to or lower than a predetermined speed after the alarm outputting step S320. Here, the section detecting means 371 is additionally provided after the first section detecting means 371a and the second section detecting means 371b in the first section A and after the alarm outputting step S320, And applies the detected speed to the control unit 310.

The control unit 310 computes again the traveling vehicle as the distance and the time difference of the vehicle sensing signal of the section detecting means 371 and compares it with the set speed.

The warning sound off step S340 is a step of turning off the sound output means 393 when the speed of the traveling vehicle is lower than the set speed in the setting speed determination step 330. [ In other words, the control unit 310 proceeds to the secondary section warning step (S400) by inducing the speed of the vehicle being driven to decelerate at a predetermined speed in the first section (A).

FIG. 9 is a flowchart showing a secondary section warning in the control method of the road alarm system according to the present invention.

The vehicle sensing step S410 is a step in which the control unit 310 receives the vehicle sensing signal from the section sensing unit 371 installed in the second section. The control unit 310 receives the detection signal of the driving vehicle 410 that has passed through the first section A and entered the second section B from the third section detection unit 371c installed in the second section B do.

The second alarm outputting step S420 is a step in which the control unit 310 controls the second information display means 391b to receive the vehicle detection signal from the third section detecting means 371c, ), And a warning message including one or more of lane change, stop, and slow-down. Here, the second information display means 391b outputs, for example, a character indicating a mist generation period and a character instructing to slow down from a point several meters ahead. Or the second information display means 391b can output a character or light emission indication to change the lane on the secondary lane if there is a vehicle stopped in the primary lane.

The light emission output step S430 is a step in which the control unit 310 controls the road surface light emission means 392 to control at least one of changing, stopping, and slowing down the lane on the road surface. For example, the road surface light emitting means 392 can be lighted from red in the first lane, green or blue in the second lane to indicate the lane change, or to warn the lane to lighten yellow over the electric line.

The vehicle passing determination step S440 is a step of determining whether the driving vehicle has passed through the second section through the section detecting means 371 embedded after the point of the accident. The control unit 310 determines the presence or absence of a traveling vehicle to save the electric energy of the road surface light emitting means and the second information display means 391 and controls the second information display means 391 and the road surface light emitting means It is determined whether or not the vehicle has passed through the section.

The off step S450 is a step in which the controller 310 turns off the second information display means 391b and the road surface light emission means 392 when the vehicle is absent or passes through the second section B in the vehicle passing determination step S440 .

As described above, according to the present invention, it is possible to prevent a secondary accident such as a chain collision accident by sequentially warning the alarm and the speed deceleration in a section where the driver's field of view is restricted, such as a mist or a curve.
