The terms or words used in the present specification and claims should not be construed as being limited to their ordinary or dictionary meanings, and the inventor may appropriately define the concept of the term in order to best describe his invention. Based on the principle, it should be interpreted as meaning and concept consistent with the technical idea of the present invention.

Accordingly, the embodiments described in this specification and the configurations shown in the drawings are only the most preferred embodiments of the present invention and do not represent all the technical spirit of the present invention, so various equivalents that can be substituted for them at the time of the present application It should be understood that there may be variations and examples.

Hereinafter, prior to the description with reference to the drawings, it is not shown or specifically described for the known components that are not necessary to reveal the gist of the present invention, that is, a known configuration that can be added obviously by those skilled in the art with ordinary knowledge. reveal the sound

The present invention according to Figure 1 of the accompanying drawings, a traffic light including a vehicle traffic light and a pedestrian traffic light; a detector including a camera installed on a pole (pole) of a pedestrian traffic light and photographing the area around a crosswalk and a radar for detecting a vehicle; an electric sign installed around the crosswalk to output predetermined image information; IP emergency bell that performs emergency call function; and a server that performs a function through information transmission and reception.

The above-described traffic light or IP emergency bell may be implemented as shown in FIG. 3 of the accompanying drawings.

In this case, it is preferable that the electric sign board be installed separately using a pole of a walking signal light and a separate pole, but it may be installed above the traffic light using a pole of a walking or vehicle traffic light.

In addition, the IP emergency bell may be provided in various locations such as a pole of a traffic light or a pole of an electric sign board, and is implemented to communicate with a control center having a server.

Since these IP emergency bells are installed and applied in various ways around traffic lights, a detailed description thereof will be omitted.

On the other hand, although it is described that the above-described detector includes a camera and a radar through the drawings, it is not necessarily limited thereto. For example, the camera functions to take pictures and the laser functions to detect the license plate of the vehicle. If all of these functions can be performed through the camera, it may be configured to include only the camera.

In addition, the above-mentioned detector is to use the known published technology applicable at the time of filing of the present invention.

For example, deep learning artificial intelligence technology is an example, which can be applied to all technologies applicable to those skilled in the art at the time of filing of the present invention, for example, detection area deep learning described in Application No. 10-2018-0070284 An example is the technology of the vehicle enforcement system based on the vehicle.

In addition, the predetermined function of the above-described server is to receive a signal from a traffic light and a detector, determine the violation status of the vehicle, detect the violation vehicle, generate image information to be output on the electronic display board based on it, and transmit it to the electronic display board function means.

At this time, although the communication module for transmitting and receiving information is not described in the drawings, it should be understood that the function is provided.

Hereinafter, the server will be described with reference to FIG. 2 of the accompanying drawings.

The server according to FIG. 2 of the accompanying drawings includes a traffic light information receiving unit, a traffic light failure determination unit, a violation situation determination unit, a violation vehicle detection unit, an electronic display board output information generation unit, a non-vehicle object reading unit, and a violation enforcement unit and a vehicle path mapping unit.

The traffic light information receiving unit receives the traffic light information from the traffic light.

In this case, the traffic light information means lighting color information of the traffic light.

The traffic light failure judging unit determines that the signal communication function is broken when no traffic light information is received from the traffic light, and when there is no change in the traffic light information even after a predetermined time elapses, that is, when the lighting color does not change, the traffic light is functionally defective I think this is

In this case, the predetermined time refers to a normal time sequence in which the color of the traffic light is changed. For example, when the blue light should have been turned on but not turned on, or when the vehicle traffic light and the walking signal light are compared, the vehicle traffic light turns red. When turned on, the pedestrian traffic light should be turned on in blue, but the blue lighting of the pedestrian traffic light is not made even though the vehicle traffic light is turned on in red.

The violation situation determination unit performs a function of determining the violation situation of a specific vehicle based on the traffic light information received through the traffic light information receiving unit and information received from the detector.

For example, it is to determine the violation status of the vehicle from when the vehicle traffic light turns yellow until the next blue light turns on, and it is determined that the vehicle violates the stop line or crosswalk by analyzing the image captured by the detector's camera.

As another example, when the vehicle traffic light is a signal that does not allow a U-turn, the violation of the vehicle is determined, and the image captured by the detector's camera is analyzed to determine whether the vehicle makes an illegal U-turn or violates the center line.

The violation vehicle detection unit, when the determination of the violation situation is made by the violation situation determination unit, detects the vehicle of the image to detect the license plate.

The electric billboard output information generating unit, when a violation vehicle is detected through the offending vehicle detection unit, generates electric sign output information to be output to the electric sign based on this, and transmits the generated electric sign output information to the electric sign board.

In this case, the vehicle number of the offending vehicle and an image of the vehicle may be output to the electronic sign output information. In this case, two digits of the vehicle number may be treated with an asterisk (*).

Or, as simple text, "Character 02** vehicle, the stop line has been violated." It is also possible to output such a phrase.

The non-vehicle object reading unit performs a function of reading when an object other than a vehicle (bicycle, motorcycle, person, etc.) is detected on the crosswalk through the camera of the detector. To this end, the server may pre-store pixel information on objects other than the vehicle, and compare the image obtained through the camera with the pre-stored pixel information to read objects other than the vehicle. However, the present invention is not limited thereto, and a method that can be replaced by a person skilled in the art for the object detection function may be employed.

The non-vehicle object reading unit may perform a reading function at all times regardless of whether a traffic light is turned on.

In this case, when an object other than the vehicle is read through the non-vehicle object reading unit, it may be linked with the electronic sign output information generating unit to output the existence of an object on the crosswalk through the electric sign board.

Accordingly, the driver of the vehicle located on the road recognizes the presence of an object in the crosswalk through the electronic signboard, thereby preventing an unfortunate accident from occurring.

For example, by reading an object other than the vehicle when the pedestrian traffic light is lit blue, it is possible to prevent the vehicle from starting recklessly even if there is an elderly person or an animal crossing at a slow speed.

As another example, when an object other than the vehicle is read when the vehicle traffic light is lit blue and there is a person performing jaywalking, it is linked to the electronic signboard output information generating unit and output is made on the electric signboard. Means (eg, emergency output through speaker audio output, flashing output, etc.) may be used to notify the driving vehicle of the crisis.

The violation enforcement unit performs a function of reporting the vehicle license plate detected through the violation vehicle detection unit to a related organization.

For example, the server according to the present invention can be reported by transmitting the license plate of the offending vehicle together with the image while interworking with the National Police Agency server.

The vehicle route mapping unit, when a violation vehicle is detected through the violation vehicle detection unit, from the yellow light of the vehicle traffic light, which is the point at which the determination of the violation situation starts by the violation situation determination unit, until the next blue light is turned on It functions to map the vehicle path of the corresponding vehicle.

In this case, the vehicle route and the line are displayed in the mapping of the vehicle route.

The line will be described below with reference to FIG. 4 of the accompanying drawings.

The vehicle path is mapped as shown in FIG. 4 by estimating the location of the vehicle by determining the distance from the detector to the vehicle through the detector's radar (refer to the dotted line box in FIG. 4 ). In this case, by configuring a plurality of radars in the case of multiple lanes, mapping in multiple lanes may also be performed.

This will be described with reference to FIG. 4 of the accompanying drawings.

4 of the accompanying drawings as an example, when a violation vehicle is detected, the path the vehicle has moved from the yellow light of the vehicle traffic light to the next blue light of the vehicle traffic light is determined periodically (for example, in seconds), A route is processed as mapping information generated, and a line (refer to the dotted line in FIG. 4 ) indicating a timeline for yellow and red lights of vehicle traffic lights is displayed in the processed mapping information.

At this time, the line display processing may be to perform the line display processing immediately when the server receives the yellow light information from the traffic light in connection with the traffic light information received from the traffic light, and the traffic light does not have a separate external control. Since the signal lighting interval is made the same periodically as above, a separate RTC may be applied to perform time-based line display processing.

The mapping information processed in this way prepares and stores a separate database on the server, which is used as evidence when a complaint is filed or a dispute arises about vehicle violation information.

That is, it is assumed that mapping information as shown in FIG. 4 of the accompanying drawings is prepared, and when a civil complaint is filed from the owner of the vehicle, the mapping information is used as the basis.

Depending on the design condition, the server may store the mapping information processed through the vehicle path mapping unit and provide the analysis information together when used later, and may further include a mapping information analysis unit for this purpose.

The mapping information analysis unit performs a function of analyzing whether there is a violation by the system when the previously stored mapping information is used as evidence by the borrower's complaint. The analyzed information of the mapping information analysis unit may be used as other evidence when arguing for violations later.

For example, based on the mapping information, a process of confirming the detected distance of the corresponding vehicle is performed.

At this time, since the line according to the yellow light and the line according to the red light are based on the signal system, they are always at the same location. do.

In addition, distance information for crosswalks and stop lines based on radar is also stored in advance.

Then, when the vehicle is first detected, the distance information on the distance based on the radar is determined, and it is determined whether the distance information of the vehicle is an intermediate value between the distance information of the line according to the yellow light and the line according to the red light. .

For example, assuming that the distance of the line according to the yellow light is 50 m and the distance of the line according to the red light is 100 m, it is determined whether the distance at which the vehicle is initially detected is 75 m or less.

In this process, if the detection distance of the vehicle is 75 m or less, there is a possibility that the owner of the vehicle may not have recognized the yellow signal. In other words, the detailed review is based on the review of the relevant institutions.

If the detection distance of the vehicle exceeds 75 m, the distance detected by the vehicle is determined when the red light of the vehicle traffic light is turned on.

At this time, if the detection distance of the vehicle has a longer distance than the line according to the red light, it is analyzed that there is no possibility of violating the stop line. If it is short, it is analyzed to be a stop line violation, and if it is shorter than the distance to the crosswalk, it is analyzed to violate the crosswalk.

What has been described above using the drawings is to describe only the main points of the present invention, and as many designs are possible within the technical scope, it is obvious that the present invention is not limited to the configuration of the drawings.
