The present invention relates to an unmanned traffic signal enforcement control device, in particular, to control the traffic law violations, such as lane violations, signal violations, speeding, intelligent complex traffic signal enforcement control to detect a variety of traffic information, such as accidents, traffic volume An apparatus and a control method thereof are provided.

In modern times, vehicles are recognized as necessities rather than luxury goods, and vehicles are rapidly increasing, and traffic accidents caused by vehicles are also rapidly increasing.

The main cause of such traffic accidents can be seen as a violation of traffic laws due to driver's safety insensitivity. Therefore, it is essential to crack down on traffic laws by drivers with unclear accidents even for the safety of innocent drivers.

Currently, traffic violations are subject to crackdowns or use of unmanned crackdown equipment, which is a growing trend.

Such unmanned enforcement equipment, by cutting the road surface to recognize the presence of the vehicle through a means such as a loop (loop) detector to detect signal violations, speed regulation, lane violations,

The unmanned enforcement device differs in each processor and system for each of the detailed enforcement items such as signal violation, overspeed enforcement, lane violation, etc., and is equipped with a processor corresponding to the enforcement item for each installation location, The intermittent device is installed and processed.

That is, one system is in charge of each item individually such as signal violation control device, overspeed control device, and lane violation control device.

As described above, the conventional unmanned enforcement devices are functionally independent from each other. This means that a separate system exists according to any one of the purposes of detecting a signal violation and a speeding violation vehicle, as described above.

In addition, since these unmanned enforcement devices process multiple cameras in one processor, only one interruption device is installed in one lane, and a single operation is performed in one processor. In order to prevent changes in the lanes due to discovery, unmanned enforcement devices should be provided for the lanes.

Therefore, the cost of the installation of the unmanned enforcement device and the maintenance of the following will also follow.

In addition, according to the conventional unmanned enforcement system, there is no problem when detecting the violation vehicle through the captured image of the vehicle traveling at a certain speed or more at a certain point such as speeding, but the vehicle enters the control point. In the case of a signal violation or a dedicated lane violation that requires a certain driving to be satisfied after a certain driving, many problems have been raised with conventional systems for photographing a simple point.

In view of the above, the present invention intends to propose a complex unmanned traffic enforcement device including traffic information such as traffic volume, as well as violation of traffic laws such as signal violation, speeding, lane violation, and the like. It is possible to detect violations and to detect traffic information.

The operation of the embodiment of the present invention having such features and the like will be described in detail with reference to the accompanying drawings.

The vehicle tracking area is set, and the vehicle tracking area is continuously photographed by the analog camera 1.

At this time, since the analog camera 1 has a wide shooting range, the shooting range can be set for all lanes, so the vehicle tracking area is made for the tram line.

As described above, the analog image photographed by the analog camera 1 is signal-processed by the analog image signal processing unit 2, and the vehicle image detection unit 3 extracts the edge portion of the processed signal to detect the vehicle. .

As described above, the analog image photographing the movement of the vehicle is a vehicle tracking image through the detection signal processing unit 6. The analog image compressed by the main controller 10 is stored in the main memory unit 12 or the external memory unit 13. Will be saved.

The main controller 10 transmits the stored image to the central server 100 at predetermined intervals or partially transmits the stored image in response to a request from the central server 100.

The number of vehicles passing through the corresponding point through the loop detector 4 together with the vehicle image detection unit 3 is extracted and transmitted to the central server 100 as traffic information (traffic volume) together with the location, date, and time. do.

When the event is detected by the detection signal processing unit 6 through the loop detector 4 or the sound wave sensor unit 5 in such an operation state, the main control unit 10 makes a digital photographing request, and accordingly, the digital camera controller In (8), the digital camera 7 is controlled to photograph the vehicle at a predetermined shooting position.

The digital image photographed as described above is signal-processed through the digital signal processor 9, corrected and processed, and input to the main controller 10.

The main control unit 10 stores the captured image in the main memory unit 12 or the external memory unit 13, and combines and reconstructs the analog image and the digital image obtained for the tracking of the previous vehicle. Output to send to the central server 100.

That is, the digital image due to the event is a digital image photographing the front of the vehicle, the analog image is an analog image showing the driving of the vehicle, and transmits them to the central server 100 in the form of a compressed analog image.

In addition, the main control unit 10 transmits text information such as a location, a date, and a time by using internal information.

At this time, in the main control unit 10, as shown in FIG. 3, only the portion where the license plate is located may be added to the digital image captured by the front of the vehicle and transmitted together.

This is to prevent image quality deterioration due to the transmission of the image in the compressed form, it is impossible to clearly identify the number.

In addition, in the embodiment of the present invention, it can be configured to further include a license plate recognition plate 15, so that the vehicle number information can also be transmitted as text information with the expansion of the license plate,

Recognize the license plate from the digital image photographed through the license plate recognition unit 15, extract the vehicle number described in the recognized license plate, and output this information to the main control unit 10 to be included in the text information in the main control unit 10 So that it can be transmitted along with the video of the violating vehicle.

Then, the crackdown control action for events such as speeding, signal violation, lane violation, accident occurrence, etc. provided by the present invention will be described in detail according to each event.

3 is a view illustrating a state in which an apparatus of the present invention is installed in an intersection, which will be described below with reference to this.

Figure 3 is a loop for detecting the speed of the vehicle on the road is installed at the P1, P2 point, the loop of the P2 point is an example installed on the stop line to handle the stop line sensing, loop and stop line sensor for speed detection Can be configured separately, which can be variously implemented.

First, signal violations are explained as follows.

As described above, when the vehicle is detected in the vehicle tracking area by the vehicle image detector 3, the detection signal processor 6 continues tracking according to the movement of the vehicle.

At this time, when the vehicle passes the position (P1, P2) of the loop embedded in the road, the loop detector 4 receives the detection signal of the loop, and in the detection signal processor 6 when the vehicle crosses the stop line, The state of the traffic light 16 is checked.

That is, when the detection signal processor 6 recognizes that the vehicle is detected from the loop (stop line sensing) at the P2 time point, the detection signal processor 6 receives the signal information from the traffic light 16 to determine whether the vehicle violates the signal.

If it is determined that the current driving vehicle is in violation, the vehicle image detection unit 3 continues to track the vehicle detected, and when the set photographing area point is reached, the digital camera controller 8 lanes corresponding to the violation vehicle. The head 7a or 7b or 7c is selected to command shooting.

That is, if the vehicle crossing the stop line travels for a certain distance, the signal violation will be enforced.

Subsequently, as described above, the main control unit 10 stores the captured digital image in the main memory unit 12 or the external memory unit 13, while the digital image of the violating vehicle and the analog image and position of the tracked vehicle, It is combined with text information such as date, time, violation (signal violation), vehicle number, and output to the transmission unit 11 to be transmitted to the central server 100.

In this case, the analog image of the tracked vehicle transmits the analog image tracked to the shooting point at a predetermined position beyond the stop line.

Instead of the entire video, 15 frames per second or a fixed rate is divided and transmitted.

On the other hand, the speed violation enforcement is described as follows.

As described above, as the vehicle passes through the loops at the time points P1 and P2, the loop detector 4 outputs the input of these signals to the detection signal processor 6, and the detection signal processor 6 detects these signals. The speed of the vehicle can be calculated by the difference in the input time of the signal,

The speed limit is determined by comparing the speed limit with the calculated vehicle speed.

If it is determined that the speed is violated, as described above, digital shooting is performed on the vehicle, and as in the prior art, the captured digital image is stored and transmitted to the central server 100.

At this time, textual information such as location, date, time, violation (violation rate) are transmitted along with the previous signal violation.

Therefore, when the vehicle runs at the speed higher than the specified speed in the state of the yellow traffic light and the red light at the speed higher than the specified speed, both the signal violation and the speed violation are interrupted.

4 is a view showing an example installed in a dedicated lane, to show an example of a dedicated lane violation.

Dedicated lane violations must be determined for the actual crackdown time and the crackdown vehicle, and according to the present invention, the heads 7a, 7b, and 7c in which the digital camera 7 photographs each lane are set. Therefore, since information on the dedicated lanes must be specified, each of these pieces of internal information is required to perform lane violation event determination.

The information on these includes the interruption time, the image information of the subject car, the lane setting information, and the like in the internal means of the detection signal processor 6.

As shown in FIG. 4, a lane violation event is determined by determining whether a vehicle is present and image tracking through the vehicle image detector 3 and the loop detector 4 in the corresponding lane set as a dedicated lane, and perform an action accordingly. Bar,

When the vehicle passes the point P1 and P2 where the loop is buried, the vehicle violates the speed by the above-described action, and the analog image captured by the analog camera 1 through the loop to a predetermined point in time is passed. As described above, the vehicle image detector 3 tracks the vehicle.

At this time, if the vehicle continues to travel to a certain region, the vehicle is digitally photographed at a predetermined position.

According to this, the same applies to the case where it is installed at the intersection as shown in FIG. 2, which will only be described with reference to FIG. 3.

On the other hand, the operation according to the determination of the accident occurrence event and the accident occurrence determination result is as follows.

The sound wave sensor unit 5 measures the noise around the system, and outputs the measured value to the detection signal processor 6.

The detection signal processing unit 6 calculates the interlocking noise using the input noise and the noise in the normal state, and determines the occurrence of yugo by comparing the calculated interlocking noise value with a predetermined threshold.

At this time, the threshold value for determining the accident is set in advance according to the noise value interlocked through the sound wave analysis of the noise in the normal state and the noise generated when the vehicle collides and is stored in advance.

In other words, it can be seen that the state in which the fluctuation of the noise is rapidly increased is determined as the occurrence of an accident.

As described above, when the detection signal processing unit 6 determines an event for an accident occurrence, the main control unit 10 stores the time at the time of the occurrence of the accident occurrence, and stores it in the main memory unit 12 or the external memory unit 13. Among the analog video images, the central server 100 displays the information of the accident time and the location of the analog video of a certain time (about 1 minute) before and after a certain time (about 1 minute) from the time of the accident. To send.

In other words, it is to transmit the video for 2 minutes before and after the accident, and as described above, instead of transmitting the entire video, it is to be selectively transmitted by dividing into a predetermined frame (15 frames / minute).

Therefore, it is possible to easily identify the cause of the accident or the like.

As an embodiment of the present invention, when the configuration including the license plate recognition unit 15 is used, another embodiment of the present invention control method may be configured.

It suggests ways to crack down on theft and wanted vehicles.

In the case of theft and crackdown of a wanted vehicle, digital photographing is performed on all vehicles driving at the corresponding location. The license plate recognition unit 15 recognizes the vehicle license plate using the digital image and writes the license plate. Vehicle number information is extracted.

The extracted number information is transmitted to the central server 100 in real time irrespective of the occurrence of an event, and the central processing unit 102 of the central server 100 compares the stolen and wanted list with the received vehicle number. It will hide whether the wanted vehicle.

Of course, all the digital images photographed for all the vehicles may be stored in the main memory unit 12 or the external memory unit 13, and only the analog image which is the driving tracking image of the vehicle may be stored in consideration of the capacity of the memory. have.

Therefore, when it is determined that the central server 100 is a stolen vehicle, an image of the vehicle may be obtained by requesting an image of the vehicle from the traffic control device, and if the image is analog, the main control unit 10 may be obtained. In the present invention, the analog image at the time of transmitting the vehicle number information is loaded from the main memory unit 12 or the external memory unit 13 and transmitted to the central server 100.

Therefore, the central server 100 can determine the location of theft and wanted vehicles, and can obtain images of theft and wanted vehicles, so that accurate theft and wanted vehicles can be detected.

As described above, the complex traffic control is possible for speed violation, signal violation, lane violation, accident occurrence, etc., thereby eliminating installation cost and maintenance difficulties, and through analog image tracking in real time. It is possible to provide traffic information on traffic volume, etc., and it is possible to present accurate grounds for enforcement due to the provision of vehicle driving tracking images such as signal violations, lane violations, and accident occurrences according to various event determinations.
