Based on the principle, it should be interpreted as a meaning and concept consistent with the technical idea of the present invention.

Therefore, the embodiments described in the present 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 ideas of the present invention, and various equivalents that can replace them at the time of application And it should be understood that there may be variations.

Hereinafter, prior to the description with reference to the drawings, matters that are not necessary to reveal the gist of the present invention, that is, known configurations that can be obviously added by those skilled in the art are not shown or specifically described. Make the note clear.

The present invention relates to an unmanned control system for violating vehicles around pedestrian traffic lights.

More specifically, it is regulated that a vehicle adjacent to a pedestrian traffic light invades a stop line or a crosswalk when a vehicle signal is stopped, and according to an embodiment, a center line invasion (a U-turn in an area or signal where U-turn is impossible, or an arbitrary center line) It relates to an unmanned enforcement system that can also crack down on invasion, etc.).

1 shows the configuration of an unmanned enforcement system for violating vehicles around a pedestrian traffic light according to the present invention.

The present invention according to FIG. 1 of the accompanying drawings, includes a traffic light including a vehicle traffic light and a pedestrian traffic light; A detector installed on a pole (pillar) of a pedestrian traffic light and including a camera for photographing the vicinity of a pedestrian crossing and a radar for detecting a vehicle; An electric sign installed around the pedestrian crossing and outputting predetermined image information; IP emergency bell performing an emergency call function; And a server that performs a function through information transmission and reception.

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

3 shows an example in which the unmanned control system for violating vehicles around a pedestrian traffic light according to the present invention is built around a pedestrian traffic light.

In this case, the electric signboard may be preferably installed separately using a pole pole of a pedestrian traffic light and a separate pole, but may be installed above the traffic light using a pole pole of a pedestrian or vehicle traffic light.

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

Since such an IP emergency bell is variously installed and applied around a conventional traffic light, a detailed description will be omitted.

Meanwhile, although the above-described detector is described to include a camera and a radar through the drawings, it is not necessarily limited thereto. For example, the camera functions as a photographing 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-described detector uses a publicly known technique applicable at the time of filing of the present invention.

For example, deep learning artificial intelligence technology is an example, which can apply all technologies applicable to a person skilled in the art at the time of filing of the present invention.For example, deep learning in the detection area described in application number 10-2018-0070284 An example is the technology of the based vehicle control system.

In addition, the predetermined function of the above-described server is to receive signals from traffic lights and detectors, determine the violation status of the vehicle, detect the vehicle in violation, and then generate image information to be output on the electronic display and transmit it to the electronic display. Means the ability to do.

In this case, although a communication module for transmitting and receiving information is not described in the drawing, it should be understood that a function is provided.

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

Figure 2 shows the server configuration of the unmanned enforcement system for violating vehicles around a pedestrian traffic light according to the present invention.

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 violating vehicle detection unit, an electric sign output information generation unit, a non-vehicle object reading unit, and a violation enforcement unit. And, it is configured to include a vehicle path mapping unit.

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

At this time, the traffic light information means information on the lighting color of the traffic light.

The traffic light failure determination unit determines that the traffic light communication function has failed when the traffic light information is not received from the traffic light, and if there is no change in the traffic light information even after a predetermined period of time, that is, when the lighting color does not change, the traffic light is functionally malfunctioning. I judge this to be.

At this time, the predetermined time refers to a normal time sequence in which the color of the traffic light is changed.For example, when blue light should have been lit but not lighted, or when a vehicle traffic light and a pedestrian traffic light are compared, the vehicle traffic light is red. When it is turned on, the pedestrian traffic light should be lit blue. An example is the case where the pedestrian traffic light does not light blue even though the vehicle traffic light is lit red.

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

For example, it is to determine the violation situation of the vehicle from the yellow light on the vehicle to the next blue light, by analyzing the image captured by the camera of the detector to determine that the vehicle has invaded a stop line or a crosswalk.

As another example, when the vehicle traffic light is a signal that does not allow a U-turn, it is to determine the violation of the vehicle, and to determine that the vehicle is making an illegal U-turn or invading the center line by analyzing the image captured by the camera of the detector.

The violating vehicle detection unit detects the vehicle license plate by detecting the vehicle in the video when the violation situation is determined by the violation situation determination unit.

When the violating vehicle is detected through the violating vehicle detection unit, the electronic display output information generation unit generates electronic display output information to be output on the electronic display based on this, and transmits the generated electronic display output information to the electronic display.

At this time, the display board output information may be to output the vehicle number of the violating vehicle and an image of the vehicle. In this case, the vehicle number may be treated with an asterisk (*) for two digits.

Or, as a simple text, "02 characters 02** vehicle, stop line has been violated." You can also display phrases such as.

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 detector's camera. To this end, the server may pre-store pixel information on objects other than the vehicle, and compare the image acquired through the camera with the previously 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 an object detection function may be employed.

The non-vehicle object reading unit may perform a reading function at all times regardless of lighting of a traffic light.

In this case, when an object other than the vehicle is read through the object reading unit other than the vehicle, it is interlocked with the electronic display output information generation unit to output the existence of the object on the crosswalk through the electronic display panel.

Accordingly, the driver of the vehicle located on the road recognizes the existence of an object on the crosswalk through the electric sign, so that an unfortunate accident can be prevented.

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 indiscriminately even if there is an elderly person or an animal crossing a slow speed.

As another example, when the vehicle traffic light is lit blue and there is a person performing the crosswalk, when reading an object other than the vehicle, it is linked to the electronic display output information generation unit and when output to the electronic display is performed, alerts can be made. A means (eg, emergency output through speaker audio output, flashing output, etc.) may be used to notify the vehicle being driven of a crisis.

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

For example, the server according to the present invention may be linked with the National Police Agency server and transmit the license plate of the violating vehicle along with an image to report it.

When the violating vehicle is detected through the violating vehicle detection unit, the vehicle path mapping unit includes from the yellow light of the vehicle traffic light at the time when the violation situation determination starts by the violation situation determination unit until the corresponding vehicle traffic light is next blue light. It functions to map the vehicle path of the vehicle.

At this time, the vehicle path and the line are displayed on the vehicle path mapping.

The line will be described below through FIG. 4 of the accompanying drawings.

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

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

4 is an example illustrating the mapping function of the unmanned enforcement system for violating vehicles around a pedestrian traffic light according to the present invention.

4 of the accompanying drawings, for example, when a violating vehicle is detected, the path of the vehicle moving from the yellow light of the vehicle traffic light to the next blue light of the vehicle traffic light is determined periodically (e.g., in seconds). The route is processed with the generated mapping information, and the processed mapping information displays a line (refer to the dotted line in FIG. 4) indicating a timeline for the yellow and red lights of the vehicle traffic light.

At this time, the line display processing may be to perform line display processing immediately when the server receives the traffic light information about the yellow light from the traffic light in connection with the traffic light information received from the traffic light, and the traffic light has no external control. Since the signal lighting intervals are made equally at regular intervals, a separate RTC may be applied to perform time-based line display processing.

The mapping information mapped in this way is prepared and stored in a separate database on the server, which can be used as basis data when a civil complaint is filed or a dispute arises about the vehicle violation information in the future.

That is, it is assumed that the mapping information as shown in FIG. 4 of the attached drawing is provided, and when a civil complaint is filed by the vehicle owner, the mapping information is used as the basis data.

Depending on the design conditions, the server may store the mapping information processed through the vehicle route mapping unit and provide analysis information when using it later, and may further include a mapping information analysis unit for this purpose.

The mapping information analysis unit performs a function of analyzing whether or not the system is violated when the previously stored mapping information is used as a basis for filing a complaint by the borrower. The analyzed information of the mapping information analysis unit can be used as other evidence when controversy about violations in the future.

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

At this time, the line according to the yellow light and the line according to the red light are based on the signal system, so they are always the same position, so that the server (or database, etc.) pre-stores the distance information based on the radar. do.

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

And, 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 50m and the distance of the line according to the red light is 100m, it is determined whether the distance detected by the vehicle is 75m or less initially.

In this process, if the detection distance of the vehicle is 75m or less, since there is a possibility that the vehicle owner did not recognize the yellow signal, the mapping information analysis unit performs an analysis that does not determine whether a violation has occurred. In other words, the detailed review is based on the review of the relevant agency.

If the detection distance of the vehicle exceeds 75m, the vehicle detects the detected distance when the red light of the vehicle traffic light is made.

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

What has been described with reference to the drawings above is a description of only the main matters of the present invention, and it is obvious that the present invention is not limited to the configuration of the drawings as various designs are possible within the technical scope.
