In the prior art, sensors are installed at regular intervals around a curve road, When the vehicle enters the center line, the sensors detect the vehicle and make an alarm lamp sound, thereby enabling the drivers to recognize the situation that the center line has invaded, thereby inducing safe driving or defensive driving.

As another example, Korean Utility Model Registration No. 20-0440380 entitled "Mist Alarm System" has been proposed. In the prior art, a detection sensor composed of an illuminance sensor and a temperature / humidity sensor is installed in a fog area, It is a technology that causes the driver to display safe driving or defensive driving by displaying the visibility distance and the traveling speed which are integrated in the road situation to the driver by a road signboard or a warning light.

However, the above-mentioned conventional technology, including the above-mentioned driving speed of a region difficult to secure visibility, stagnation due to the traveling speed, the center line of the vehicle coming in opposition or reverse, the stagnation due to fog or the temperature and humidity of the section, There is not provided means for displaying the concentration, the duration of the fog, etc. to the driver in a lump, as well as a method for transmitting the information to the terminal such as the driver's mobile phone or navigation system in real time is not provided. A safety driving system that can overcome all the problems of the present invention is urgently needed.

BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention, and how to accomplish them, will become apparent by reference to the embodiments described in detail below with reference to the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. And throughout this specification, like reference numerals refer to like elements throughout.

The present invention relates to a device capable of recognizing and coping with a stagnation situation of a road which is not smoothly secured by a driver, such as a curve road, frequent fog, frequent accident, and the like.

First of all, the sensor is installed on the entrance and exit roads of the area where visibility is difficult to secure, and the traffic light is interlocked with the detection sensor on the entrance road, and the driving information of the preceding vehicle is received from the detection sensor It is noted that the present invention is directed to a road-state prediction system which can not secure a viewpoint by displaying a blinking light for each information in a traffic light so that the driver of the presently entering vehicle can recognize and cope with the road congestion state of the corresponding section in advance.

FIG. 1 is a flowchart of a road condition forecasting system that can not secure a view, provided by a preferred embodiment of the present invention.

1, a road condition prediction system according to the present invention, which can not secure the visibility of the present invention, sequentially includes a vehicle sensing unit 100, a road condition measurement unit 200, a road condition notification unit 300, (400). ≪ / RTI >

The upper vehicle detection unit 100 includes a vehicle detection sensor (not shown) disposed in a pair of an entrance road A and an exit road B, A fire detection sensor 120 for detecting the presence or absence of fog and a concentration of fog by installing a humidity sensor at a predetermined interval in the corresponding interval, (130).

Meanwhile, the upper vehicle detection sensor 110, the accident prevention sensor 120, and the fog detection sensor 130 all operate with one processor unit to control the sensed information.

The upper vehicle detection sensor 110 is composed of a primary sensor 111 installed in an access road A and a secondary sensor 112 installed in an exit road B where a corresponding section is terminated, Detects the vehicle.

Although the above vehicle detection sensor 110 is not limited to the type of sensor, it can detect the vehicle running fast as in the case of a loop detector, as well as being embedded in the ground rather than a mouth-type installation method, It is preferable to use a sensor constituted by a buried-type installation method for sensing only the air-tightness.

The upper vehicle detection sensor 110 is composed of two sets of a primary sensor 111 and a secondary sensor 112. The upper primary sensor is installed in an access road A where a section in which a view is not secured starts The second sensor senses a vehicle which is installed in the exit road (B) where the section in which the field of view can not be secured is terminated, and the vehicle is out of the corresponding section.

On the other hand, the upper secondary sensor 112 is installed at a position of 100 ~ 150M at the end point rather than at the end point of the exit road so that the driver can recognize the road condition of the corresponding section and then brake the vehicle So that it is possible to secure a sufficient distance therebetween.

The above-mentioned accident prevention sensor 120 is a means for preventing large-scale accidents in advance by detecting other vehicles or vehicles running in the opposite direction from the center line in an area in which visibility can not be ensured.

The upper accident prevention sensor 120 is further provided with a secondary auxiliary sensor 121 in the reverse direction at a position where the secondary sensor 112 is installed in a reverse direction of about 10 to 20 meters, After passing through the embedded secondary sensor 10 ~ 20M after entering, the secondary sensor senses it and transfers the information to the processor unit. Particularly, the accident prevention sensor 120 can not recognize the passage of the secondary sensor 121 after entering the primary sensor 111, Is recognized.

The upper fog detection sensor 130 detects the presence or absence of fog, the concentration of fog, and further the duration of the fog in an area in which visibility can not be secured, and provides the information only to the vehicle in operation.

 Preferably, the upper fog detection sensor 130 uses a humidity sensor that electrically detects the humidity by using the property that the resistance value dielectric constant or the like of the organic polymer or ceramic changes due to the water vapor in the air, Or at a predetermined interval on the center line to detect the presence or concentration of fog in the relevant section.

In addition, the ambient temperature outside the section and the temperature of the section are measured in real time, and then the ambient temperature is substituted to determine the duration of the fog.

The upper road condition measurement unit 200 measures the time from when the vehicle that has passed through the primary sensor 111 installed in the access road A in the section where the view is not secured reaches the secondary sensor 112 The presence or absence of the fog, the concentration, and the duration of the fog are detected from the fog detection sensor 130, and the presence or absence of the fog, the concentration, and the duration are determined.

The upper road condition measurement unit 200 measures the distance from the point where the primary sensor 111 is installed to the point where the secondary sensor 112 is installed and sets the distance to the processor unit 140. This is because, Since the shape and distance may vary, the distance between the two sensors is arbitrarily set according to the situation of the road.

The upper road condition measuring unit 200 classifies the measurement standards of the moving speed of the vehicle into three types. For example, if the vehicle travels within 0 to 20 km, it is judged to be abnormal. If the vehicle travels within 20 to 50 km, it is judged to be normal. If the average speed is 50 km or less, To the processor unit.

The road condition measuring unit 200 detects the vehicle traveling in the opposite direction through the secondary sensor 112 and detects the vehicle traveling in the reverse direction through the secondary sensor 112, The concentration, the duration, and the like of the fog by analyzing the ambient humidity of the relevant section in real time.

The up road situation informing unit 300 is a step of arranging the information detected by the road condition measuring unit 200 by the processor unit 140 and delivering the corresponding period to the drivers of the traveling vehicle.

First, the road-state notification unit 300 further includes a traffic light 310 on the entrance A of the section where the view can not be secured, and transmits the congestion or the road condition of the corresponding section through the blinking of the traffic light.

For example, according to a preferred embodiment of the present invention, the flashing light of the traffic light 310 is divided into three sections, the first section 311 is red, the second section 312 is yellow, and the third section 313, Is blue.

The light color of the upper signal lamp 310 means that when the blue light is on, like the signal of a typical traffic light, there is no congestion on the front road, so the vehicle is traveling in a state of maintaining the speed. When the yellow light is on, It means to induce deceleration. Finally, when the red light is on, there is a stagnation in front, so it means to slow down and stop.

As described above, the traffic light 310 enters the primary sensor 111 and corresponds to the speed of the vehicle passing through the secondary sensor 112 or the traveling time of the vehicle passing through the secondary sensor 112 in different colors of the first, second, and third sections 311, 312, and 313 It lights up the divided blinking lights and induces the driver to prevent the accident by preventing the driver from recognizing the congestion situation of the relevant section according to the turned on color.

In addition, the above signal lamp is provided with an electric signboard on one side, and the temperature and humidity of the current section measured in real time is provided on the electric signboard, and the concentration of fog due to humidity, the range of fog, and the maintenance time of fog are provided.

For example, the principle of the driver's road situation notification method using the above traffic light is as follows, and the following description will be made based on the contents described in the road condition measurement unit 200. [

The upper road condition measuring unit 200 classifies the measurement standards of the moving speed of the vehicle into three types, for example, if the vehicle travels within 0 to 20 km under the assumption that the average speed of the section in which the view is not secured is 50 km If it is judged abnormal, it is judged to be normal when driving within 20 ~ 50km, and it is judged to be normal when driving over 50km.

First, the traffic lights are divided into a first section 311, a second section 312, and a third section 313 in accordance with the traveling speed differentiated into three types of abnormal, normal, and normal.

Second, the first section 311 of the traffic light is composed of red light, the second section 312 is yellow, and the third section 313 is blue.

Third, the upper signal lamp 310 is based on that the blue light is normally on.

Fourthly, the time when the vehicle moves from the moment the primary sensor 111 senses the vehicle that has passed through the access road A of the section where the view can not be ensured is measured, and when the vehicle reaches the secondary sensor 112 3, and 31, and lights the signal lamp 310 to recognize the current road situation to the driver of the next entering vehicle.

Fifth, when the vehicle coming from the other direction of the driver enters the secondary sensor 112 in an area where the view can not be secured and attempts to reverse the vehicle passing through the secondary auxiliary sensor 121, the red light of the traffic light is repeatedly Notice that there is a car that is flickering and reversing on that section.

Sixth, the temperature and humidity of the current section measured in real time on the electric signboard 320 provided on one side of the traffic light 310 are provided, and the concentration of the mist due to humidity, the range of the mist, and the maintenance time of the mist are provided So that the driver can recognize the situation of the current section in advance in the fog and induce the defensive driving.

Since the driver of the real time notification unit 400 can not check the signal lamp 310 again, the driver of the vehicle can not recognize the road condition of the corresponding section in real time Guide.

For example, in a state in which a program set in the driver's navigation or an application for communicating the situation of the road to the smartphone of the driver is installed, an environment of Wifi or Bluetooth is created in a zone in which a view can not be secured, Not only the overall road situation information of the driver, but also various kinds of guidance messages such as a text message and a notification sound are used.

It is also possible to precisely check the overall condition of the road and notify the driver who enters the section of the road in real time, as well as to inform the driver in real time about the road situation information of the section . In addition, when a traffic congestion occurs in the relevant section, the situation occurrence alarm is immediately transmitted to the road traffic management center, and it is possible to grasp the situation quickly and arrange it.

Meanwhile, the users installing the application provided by the real-time notification unit 400 can intercommunicate with each other and can check the current status of the user according to the authority of the user and disclose it to other users.

For example, when a vehicle is parked on a road or a new road due to a failure or fuel shortages, the user who wants to enter the relevant section is transferred to an application in which the problem vehicle is located, .

FIG. 2 is a diagram showing a schematic progressing step of a road condition forecasting system which can not secure a view, according to a preferred embodiment of the present invention.

1) Start: Start means that the vehicle enters a section where visibility is difficult to obtain.

2) Passing the primary sensor: Passing the primary sensor means that the primary sensor senses the vehicle while passing through the entrance of the section where the vehicle is difficult to obtain visibility.

3) Start of processor part measurement: Start of processor part measurement passes through the entrance of the difficult-to-view area, and the first sensor senses the vehicle and delivers the sensed information to the processor part. It means to measure the time until the vehicle leaves the section.

4) Passing through the secondary sensor: When the vehicle entering through the primary sensor travels through the relevant section and leaves the exit path where the secondary sensor is installed, the secondary sensor senses the vehicle and transmits the sensed information to the processor It says.

5) End of processor part measurement: It means that the time measurement started from sensing the vehicle entering the primary sensor is terminated while leaving the secondary sensor.

6) Processor Judgment: According to the time measurement of the vehicle, the processor selects one of the blinking lights by discriminating the signal lamp as blue, yellow, or red, and instructs the lamp to turn on.

7) Signal lamp lighting: Signal lamp lighting means that any one of blue light, yellow light, red light, etc. is blinked on the signal light according to the above processor part's instruction, and induces the driver to recognize the current road situation.

8) When the 2-segment setting time is over: When the 2-segment setting time is exceeded, if the time measurement started from the detection of the vehicle entering the primary sensor does not arrive within the set time of the processor before leaving the secondary sensor, Yellow light ".

9) When 1 section setting time is exceeded: If 1 section setting time is exceeded, if the time measurement started from the detection of the vehicle entering the 1st sensor does not arrive within the set time of the processor before leaving the 2nd sensor, Red light is lit.

The system for predicting the condition of a road which can not be secured by the above-mentioned system can be described as various examples.

Before describing various embodiments, the distance between the primary sensor and the secondary sensor is 200M, and according to lighting standards of the first, second, and third sections of the corresponding signal lamp, the red light indicates that the speed of the vehicle is less than 0 to 20 km, The speed proportional time will be on for more than 10 seconds, the yellow light will be on when the speed of the vehicle is less than 20 ~ 50 km, the speed proportional time is less than 10 seconds for more than 4 seconds, , And the speed proportional time is based on lighting when less than 4 seconds, and the basic lighting of traffic lights is blue.

When the vehicle passes through the primary sensor by entering a road which is impossible to obtain the sight, the primary sensor senses the vehicle and transmits the sensed information to the processor, and the processor starts measuring the time for the vehicle.

The signal lamp automatically lights the amber light when the standard time of 4 seconds is exceeded before the vehicle arrives at the secondary sensor.

If the vehicle does not reach the secondary sensor even when the amber light is on, the processor measures the time duration, and when the reference time of 4 seconds, in which the red light is lit, is exceeded, the traffic light is replaced with a red light, do.

When the vehicle passes through the primary sensor by entering a road which is impossible to obtain the sight, the primary sensor senses the vehicle and transmits the sensed information to the processor, and the processor starts measuring the time for the vehicle.

If the vehicle passes through the secondary sensor 4 seconds before the yellow light of the traffic light lights up, the traffic light keeps the blue light and the process is terminated.

When the vehicle passes through the primary sensor by entering a road which is impossible to obtain the sight, the primary sensor senses the vehicle and transmits the sensed information to the processor, and the processor starts measuring the time for the vehicle.

The signal lamp automatically lights the amber light when the standard time of 4 seconds is exceeded before the vehicle arrives at the secondary sensor.

If the vehicle passes through the secondary sensor 10 seconds before the red light is lit in the state that the amber light is on, the process is terminated with the traffic light maintaining the yellow light, and after a predetermined time, .

When the vehicle is approaching a road which is not capable of securing a view, the vehicle facing the other road enters the secondary sensor and enters the secondary sensor, passes through the secondary sensor, And the processor unit starts processing the information.

When a command is issued to a traffic light based on the information processed by the processor, the traffic light flashes red light repeatedly to indicate that there is a vehicle running in reverse in that section.

The reference speed from the primary sensor to the secondary sensor is initially set to 0 to 20 km in red, 20 to 50 km in yellow, and blue in 50 km or more, The average speed of the vehicles traveling on the next day is reset, and the average speed of the vehicles collected on the previous day is reset to the reference speed, so that the vehicle speed is reset to cope with the changing road conditions every day.

The setting standard of the embodiment 5 is to collect the speed of the remaining vehicle except for the vehicle traveling at a speed of 20 km or less, which is a red light lighting standard, and based on the collected information, the average speed is changed to a standard such as a yellow light or a blue light do.

The reason why the reference speed is changed frequently as described above is that the state of the road changes every day due to the external influences such as the road surface state and the influence of the climate such as snow or rain as well as curve roads and many mist areas, It is preferable that the resetting is performed by sensing the average speed of the corresponding section that changes according to the change of the interval.

The system for predicting road conditions that can not secure the visibility of the present invention, which is implemented in the above-described manner, detects a vehicle entering the section where the view is difficult or impossible to view, detects the congestion of the corresponding section, Is displayed on a traffic light installed in the access road, and information is provided to the next entering driver to induce defensive driving. In addition, the system can be implemented with simple components such as a signal lamp consisting of three blinking lights, a loop detector, and a processor unit controlling the loop detector. The system can be installed and operated at a minimum cost in various places. A second auxiliary sensor is installed at a position where the secondary sensor is installed and it is detected that the vehicle coming in the opposite direction from the other side of the driver in the relevant section comes in through the secondary sensor and the secondary sensor, By displaying the signal on a traffic light, the driver can recognize the road condition in advance and try to drive the defense operation, so that it is possible to prevent a situation that could lead to a major accident in advance.

In addition, a humidity sensor is installed at regular intervals in each section, and the temperature, humidity, etc. of the section are detected from the humidity sensor, and the presence or absence of mist, the concentration of mist, and the maintenance time of the mist are determined It is possible to prevent an accident caused by fog by providing information to the electric signboard or the terminal of the driver separately provided at one side of the traffic light and also the driver who has already entered the relevant section and is traveling at a certain distance can grasp the traffic light notice more The processor unit and the terminal of the driver in the corresponding section can be linked to the wireless connection system such as Wi-Fi or Bluetooth to receive general information about the road condition in real time to the driver's terminal.
