The over-vehicle judging unit 520 performs a function of judging whether the vehicle is an over-ride vehicle if it is determined by the vehicle speed judging unit 510 that the speed of the vehicle is equal to or lower than the reference speed.

The over-vehicle judging unit 520 can use the congestion of the vehicle to determine whether the vehicle is an over-vehicle. In this case, the overload vehicle determination unit 520 may include a vehicle load measuring unit (not shown). In the present embodiment, the vehicle load measuring section performs a function of measuring the axial load of the vehicle using the middle shaft (or axial load detector) located on the road. The vehicle load measuring unit may be included in the overload determination unit 520, but may be included in the overload vehicle uninterruptible control system 500 separately from the overload vehicle determination unit 520.

That is, the vehicle position determination unit 575 obtains a camera image for a predetermined position with the vehicle, calculates a distance difference between the vehicle and a predetermined position based on the camera image, and determines whether the vehicle is moving to a predetermined position It can be judged.

The vehicle information transmission unit 576 has a function of transmitting information (ex. Vehicle license plate information) about the vehicle to the traffic control center when it is determined by the vehicle position determination unit 575 that the vehicle is not moving to a predetermined position .

Next, a description will be given of a vehicle driving section and a vehicle type discriminating section.

The vehicle specification calculation unit performs a function of calculating the specification of the vehicle. In the present embodiment, the vehicle specification calculation unit can calculate the height, width, and total length of the vehicle as specifications of the vehicle. Hereinafter, this will be described in detail.

First, the vehicle specification calculation unit in the case of calculating the full height of the vehicle will be described. Overall height refers to the height from the ground plane to the highest point of the vehicle, that is, the distance from the surface of the wheel to the vehicle roof. The antennas are excluded when computing the altitude.

When calculating the height of the vehicle, the vehicle specification calculation unit uses upper sensors provided at higher positions than the vehicle.

8 is an upper sensor arrangement diagram when the vehicle specification calculation unit is implemented as the first type for calculating the height of the vehicle.

The upper sensors 610a, 610b, ..., 610n are arranged along the traveling direction of the vehicle 630 on the bottom of the board 620 located on the upper side of the road. At this time, the board 620 may be implemented in a bar shape in which the traveling direction of the vehicle 630 is the longitudinal direction. It is preferable that the upper sensors 610a, 610b, ..., 610n are arranged in at least two rows on the bottom surface of the board 620 in order to increase the possibility of acquiring sensing data.

Reference numeral 640 is an example of a sensor for vehicle detection. It is preferable that the vehicle sensing sensor 640 is located in front of the upper sensors 610a, 610b, ..., 610n for smooth driving of the upper sensors 610a, 610b, ..., 610n.

When calculating the vehicle height, the vehicle specification calculation unit includes a first transmission unit, a first time value measurement unit, a first reception unit, a second time value measurement unit, a distance value calculation unit, and a vehicle height calculation unit.

The first time value measuring unit measures the first time values of the first signal output.

The first receiving unit performs a function of collecting a second signal reflected from a top surface of the vehicle using each upper sensor.

And the second time value measurement unit performs a function of measuring the second time values for which the second signal is collected.

The distance value calculation unit calculates distance values from the board to the top surface of the vehicle using the moving distance per second, the first time values, and the second time values of the first signal or the second signal.

The distance value calculation unit can calculate the distance value according to the following formula.

Distance value = (second time - first time) 占 (moving distance of the first signal or the second signal per second)

The vehicle height calculation unit calculates the height of the vehicle based on the height values from the bottom surface of the road to the board and the difference values between the calculated distance values.

The formula for calculating the vehicle height can be expressed as:

Height of the vehicle = Height value from the bottom surface of the road to the board - Distance value (distance from the board to the top surface of the vehicle)

9 is a reference diagram for showing that the distance values from the board to the top surface of the vehicle are different according to the type of the vehicle. 9 (a) is an example of a passenger car, (b) is an example of a van, and (c) is an example of a van.

A board is attached to one end of the support table 650 and upper sensors 660a, 660b, 660c, 660d, 660e, 660f are mounted on the bottom surface of the board. The upper sensors 660a, 660b, 660c, 660d, 660e, and 660f sense a target positioned downward, and arrows are acquired by the upper sensors 660a, 660b, 660c, 660d, 660e, and 660f Show distance value. Since the distance values will differ depending on the type of vehicle, in this embodiment, it is possible to determine the type of vehicle by calculating the height of the vehicle.

Next, the vehicle specification calculation unit in the case of calculating the full width or the total length of the vehicle will be described. The overall width refers to the width of the widest part of the width of the vehicle, that is, the length from the right to the left of the front wheel of the vehicle. The rearview mirror is excluded when calculating the full width. The overall length refers to the horizontal length from the front end to the rear end of the vehicle, that is, the length from the front bumper to the rear bumper.

When calculating the full width or the total length of the vehicle, the vehicle specification calculation unit uses lower sensors formed on the road.

10 is a lower sensor layout when the vehicle specification calculation unit is implemented as a second type for calculating the full width of the vehicle or a third type for calculating the total length of the vehicle.

Sub-sensors 670a, 670b, ..., 670n are embedded in the bottom surface of the road. Sub-sensors 670a, 670b, ..., 670n for calculating the full width of the vehicle are arranged in a direction perpendicular to the traveling direction of the vehicle as shown in Figure 10 (a) The sensors 670a, 670b, ..., 670n are arranged in the traveling direction of the vehicle as shown in Figure 10 (b). The lower sensors 670a, 670b, ..., 670n for calculating the full width of the vehicle in order to increase the acquisition rate of the sensing data are preferably arranged in at least two rows, and the lower sensors 670a , 670b, ..., 670n are arranged in at least two rows.

When calculating the full width of the vehicle, the vehicle specification calculation unit includes a second transmission unit, a second reception unit, a first position information acquisition unit, and a vehicle width calculation unit.

The second transmitter performs a function of generating and outputting a third signal to the lower surface of the vehicle using each lower sensor.

The second receiver performs a function of collecting the fourth signal reflected from the lower surface of the vehicle using each lower sensor.

The first position information obtaining unit obtains position information of two lower sensors located on both outer sides of the lower sensors from which the fourth signal is collected.

For example, if 50 sensors are embedded in a lane bottom of a road and the fourth signal is collected from the eighth sensor from the left to the 40th sensor, Sensor and the 40th sub-sensor from the left. The location information of each sub-sensor is stored in the DB, and the location information can be found based on the ID of the sub-sensor.

Preferably, the first position information obtaining unit detects the two lower sensors with respect to the lower sensors for which the fourth signal is collected within a predetermined time. The reason for this is to calculate the total width more precisely by excluding the case where it is reflected from other parts (ex. Rearview mirror) except the bottom surface of the vehicle.

The vehicle width calculation unit calculates a full width of the vehicle based on the position information of the two lower sensors.

The vehicle width-width calculation unit may calculate the full width of the vehicle according to the following equation (1).

Figure 112015053844206-pat00001

In the above, z means the full width of the vehicle. x 1 and y 1 denote the positional information of any one of the two sub-sensors located on both outer sides, and x 2 and y 2 denote the positional information of the other of the two sub-sensors located on both outer peripheries.

In the above equation, consideration is given to the case where the position information of the lower sensor is two-dimensional. Even when the position information of the lower sensor is three-dimensional, the entire width of the vehicle can be calculated in this manner.

When calculating the total length of the vehicle, the vehicle specification calculation unit includes a third transmission unit, a third reception unit, a second position information acquisition unit, and a vehicle length calculation unit.

The third transmitter performs a function of generating and outputting a fifth signal to the lower surface of the vehicle using each lower sensor.

The third receiver performs a function of collecting the sixth signal reflected from the lower surface of the vehicle using each lower sensor.

The second position information obtaining unit obtains position information of the two lower sensors located on both outer sides of the lower sensors from which the sixth signal is collected.

And the second position information obtaining unit preferably detects the two lower sensors with respect to the lower sensors for which the sixth signal is collected within a predetermined time. The reason for this is to calculate the electric field more precisely by excluding the case where it is reflected from other parts except the lower surface of the vehicle.

The vehicle total length calculation unit calculates the total length of the vehicle based on the position information of the two lower sensors.

On the other hand, in the present embodiment, it is also possible to recognize the vehicle type by recognizing the license plate of the vehicle. In this case, the overload vehicle uninterruptible control system 500 may further include a license plate recognition unit (not shown). The license plate recognition unit recognizes the numbers on the license plate of the vehicle. The vehicle type discrimination unit discriminates the vehicle type of the vehicle on the basis of the numbers recognized by the license plate recognition unit.

The license plate recognition unit includes a license plate image acquisition unit, a character / number region extraction unit, a number area selection unit, and a number recognition unit.

The license plate image acquiring unit acquires the license plate image by photographing the license plate of the vehicle.

The character / number region extraction unit extracts a character region and a number region from the license plate image. The character / number region extraction unit may extract the character region first from the license plate image, and then extract the number regions divided by the character region.

The number area selection unit performs a function of selecting one of the extracted number areas. The numeric region selection unit may compare the sizes of the extracted numeric regions to select a numeric region having a relatively small size and compare the positions of the extracted numeric regions in the license plate image to select the numeric region located on the left side or the upper side It is possible.

11 is a reference diagram for explaining a method of selecting a number area. The current car number in Korea is a combination of two digits, letters and four digits. The two-digit number indicates the vehicle type symbol, and the details are as follows.

Passenger cars: 01 ~ 69

Vans: 70 ~ 79

Vans: 80 ~ 97

Special cars: 98 ~ 99

As shown in FIGS. 11A and 11B, the first numeral region representing the vehicle type symbol is composed of two-digit numbers and is smaller in size than the second numeral region composed of four digits. Also, the first number area in the license plate is located on the left side or the upper side when compared with the second number area. Therefore, in this embodiment, it is possible to select the numerical area in consideration of this point.

The number recognition unit recognizes the numbers in the selected number area.

On the other hand, the license plate recognizing unit recognizes all the numbers on the license plate and provides the information on the recognized numbers to the car discriminating unit so that the car discriminating unit can discriminate the car type.

The vehicle type discrimination unit performs a function of discriminating the vehicle type of the vehicle on the basis of the vehicle specification information. As described above, in the present embodiment, the vehicle height, full width, and total length are obtained from the vehicle information.

The vehicle type discrimination unit can discriminate the vehicle type of the vehicle based on at least one specification information selected from the vehicle height, the vehicle width, and the vehicle length. In this embodiment, it is preferable that the vehicle type discriminating unit discriminates the vehicle type of the vehicle based on the height of the vehicle in consideration of the advantage of the upper sensor relative to the lower sensor.

When the upper sensor does not operate normally, the vehicle type discrimination unit discriminates the vehicle type of the vehicle on the basis of at least one of the full width of the vehicle and the total length of the vehicle. When it is desired to further improve the accuracy of the discrimination of the vehicle type, the vehicle type discrimination unit discriminates the vehicle type by further utilizing at least one of the information of the full width of the vehicle and the total length of the vehicle.

In the present embodiment, the vehicle type discrimination unit can discriminate the vehicle type from any one of a passenger car, a van, a freight car, and a special car. The vehicle type discrimination unit can have a database of the overall height, width, and length of the vehicle for each product, and then discriminate the products by product.
