However, since the vehicle information detection system employing the above-described high speed relay equipment is installed in parallel with the first and second axis detection sensors, the wheel position of the vehicle and the wheel spacing of the vehicle cannot be calculated.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 2, the present invention includes a first loop sensor 2 which detects and outputs when the left and right wheels of the vehicle 3 pass adjacent to each other and is embedded on the road 1;

A second oblique axis detecting sensor which is installed in a diagonal line at a rear end of the second axis detecting sensor 6 with a set separation distance with the first oblique axis detecting sensor 7 with respect to the right road axis. (8);

The detection data of the first and second loop sensors 2 and 5, the first and second axis sensors 4 and 6 and the first and second oblique axis sensors 7, 8 are analyzed Accurately read the tire width and the number of tires in the vehicle to distinguish between small passenger cars and small trucks, accurately identify the driving trajectories of the tires, and then obtain lubrication to correct the driving speed according to lane departure and overtaking according to the driving trajectory of the tire. It is configured to include a calculation system unit 9 for calculating the traffic information set in consideration of the post-axle weight calculation.

Here, piezoelectric sensors may be used for the first and second axis detecting sensors 4 and 6 and the first and second oblique axis detecting sensors 7, 8.

The calculation system unit 9 further includes a comparator 12 configured to compare the response signals of the first and second oblique axis sensors 7 and 8 to the threshold level and output the square wave signals. . Here, the comparator 12 is configured using the OP AMP, and converts the input analog signal into a digital signal. In this case, the comparator 12 compares a signal and a threshold level with respect to the sensor waveform and converts the signal to 1 (High) when the signal is larger than the threshold value and 0 (Low) when the signal is smaller than the threshold value.

Next, the calculation method of the apparatus of the present invention having the above configuration will be described.

As shown in FIG. 3, the method of the present invention proceeds from the initial state S1 to the vehicle entrance checking step S2 to check whether the current vehicle enters. At this time, as a result of checking during the vehicle entry confirmation step (S2), if the current vehicle does not enter the traffic information calculating device, the vehicle returns to the standby state and repeats the loop. However, as a result of checking during the vehicle entry confirmation step (S2), when the current vehicle enters the traffic information calculation device, the vehicle proceeds to the general information detection step (S3) of the vehicle and runs using the vehicle speed and occupancy time difference information. The wheelbase information is calculated and input to the calculation system unit.

On the other hand, after the general information detection step (S3) of the vehicle proceeds to the diagonal axis direction information detection step (S4) to the tire width, the tire of the running vehicle through the first and second diagonal axis sensor installed in a plurality of diagonal lines on the road The number and the running trajectory of the tire are detected and input to the calculation system unit of the traffic information calculating device.

Then, after the diagonal axis direction information detecting step (S4), the traffic information calculation step (S5) proceeds to the calculation system unit analyzes the detection data input from the various sensors including the first and second diagonal axis sensor, the high-speed driving vehicle Accurately read the tire width and number of tires to distinguish between small passenger cars and small trucks, obtain lubrication through the tire's driving trajectory, and correct the driving speed according to lane departure and overtaking according to the tire's driving trajectory. Reflect the calculation to calculate the set traffic information.

In other words, in the present invention, when the driving vehicle 3 travels in the driving trajectory of (a) and (b) as shown in FIG. The vehicle 3 is detected and reading of the driving information of the vehicle 3 starts. Then, when the vehicle 3 passing through the first loop sensor 2 enters the area (d), the axis is detected by the first axis sensor 4 and then enters the area (ㅁ). 2 The loop sensor 5 detects the vehicle 3. In addition, when the vehicle 3 enters the area (i), the axis is detected by the second axis sensor 6, and when the vehicle 3 enters the area (i) and (o) continuously, The left tire of the vehicle 3 passes through the first oblique axis detecting sensor 7, which is installed diagonally, and the right tire of the vehicle 3 passes through the second oblique axis detecting sensor 8, which is installed diagonally. Is detected.

Here, when the entry information of the vehicle 3 is detected by the sensors 2, 4, 5, 6, 7, and 8, all of the detection information is input to the calculation system unit 9.

Accordingly, the calculation system unit 9 uses the detection information of the first loop sensor 2 for the purpose of detecting the vehicle, and the detection information of the second loop sensor 2 is the vehicle length based on the occupancy time of the vehicle. Then, the overhang due to the time difference with the first axis sensor 4 is calculated, and further, the underhang due to the time difference with the second axis sensor 6 is obtained.

In addition, the calculation system unit 9 calculates the speed of the traveling vehicle by the time difference between the two sensors through the first and second axes of the first and second axis sensors 4 and 6, respectively. The number of axes is read out by counting the pulses, and the wheelbase is obtained by the time difference of the pulses. In this case, when the first axis sensor 4 and the second axis sensor 6 are axis sensors capable of performing the calculation of each axis, each axis Calculate the shaft weight with the response signal for.

On the other hand, the calculation system unit 9 is the tire width of the running vehicle, the number of tires, the running of the tire through the information detected from the first diagonal axis sensor 7 and the second diagonal axis sensor 8 installed in a diagonal line Traffic information is calculated by detecting tracks.

Here, the tire width of the traveling vehicle, the number of tires, and the running of the tire through the information detected by the first diagonal axis sensor 7 and the second diagonal axis sensor 8 in which the calculation system 9 is installed diagonally. The process of calculating the traffic information by detecting the track will be described in detail with reference to FIG. 5 as follows.

That is, when the first oblique axis sensor 7 and the second oblique axis sensor 8 are installed at an oblique angle, for example, at a 45 degree angle, the tire of the vehicle 3 travels in the direction of (e). (Dx) and dy are the same. Therefore, when the first oblique axis sensor 7 and the second oblique axis sensor 8 are installed at any angle as described above, the dy of σ can be calculated using the sin function.

   For example, FIG. 6 is a response signal of the two sensors 7 and 8 when the small passenger car 10 passes over the first and second axis detecting sensors 7 and 8 installed diagonally, wherein reference numeral 11 denotes a passenger car. The front and rear axles consisted of a single tire in the form of the tire of (10), and accordingly (12) and (13) are diagrams of the response waveforms of the sensors installed diagonally to the left and right.

FIG. 7 is a schematic diagram of response signals of the two sensors 7, 8 when the small truck 11 passes over the first and second axis sensors 7, 8, which are diagonally installed. (11) The tires of the vehicle consist of two tires on the rear axle. (16) and (17) of FIG. 7 illustrate response waveforms of sensors installed diagonally to the left and right, and (18) of the response waveforms illustrate the waveform of the rear axle of the vehicle. Two peaks are generated to distinguish the number of tires.

8 is a detailed diagram of the response waveform of FIG. 7, in which the tire width calculation and the tire type of the driving vehicle are distinguished. If inputted as, square wave like (22) is outputted.

Here, the output of the comparator 12 measures the pulse width and pulse interval of each square wave using a microcomputer (not shown) provided in the calculation system unit 9. At this time, the calculation system unit 9 determines that the tire is composed of a double wheel when two pulses are generated continuously as shown in (22), and the pulse width calculates the tire width at the traveling speed of the vehicle.

   9 is a signal waveform that is plotted for calculating a driving trajectory, lane departure degree, and roundness of a vehicle as response signals of an axis sensor installed in a diagonal line. Here, the response waveform of (23) is the response signal of the second axis sensor 6 in the region (i) of FIG.

9 (24) is a response waveform of the first diagonal axis sensor 7 installed in a diagonal line in FIG. 4 (s), and (25) is a second line formed in the diagonal line in FIG. 2 The response waveform of the diagonal axis sensor 8. 9 is a signal interval with respect to the first axis of the traveling vehicle of the first diagonal axis sensor 7 is installed diagonally with the second axis sensor (6). 9 is a signal interval with respect to the first axis of the traveling vehicle of the second oblique axis sensor 6, which is installed diagonally with the second axis sensor 6. The signal intervals 26 and 27 can calculate the displacement at the speed of the traveling vehicle, and are calculated by the above (26) and (27) when the sensors (7, 8) installed diagonally are installed at a 45 degree angle. The displacement is equal to dx of FIG. 5, and is immediately substituted with dy of (c) to immediately read both tire positions of the traveling vehicle. If the above process is performed for all axes of the vehicle, the driving trajectory of the vehicle can be obtained. Therefore, in Fig. 9, the rounding calculation is performed by adding up the displacements calculated by the sensors 26 and 27 and subtracting the starting position of the second oblique axis detecting sensor 8 to read out the rounding.

On the other hand, the value detected by the first and second oblique axis detection sensors (7, 8) of the calculation system unit 9 will be described in more detail, as shown in Figure 5, the tire of the vehicle (3) The running trajectory of the tire when passing over the sensor 8 installed by the oblique line in FIG. 4 (o) becomes dy in FIG. 5 from the reference line in FIG. 4.

Also, the x-axis of FIG. 5 is used as the reference line of FIG. 4, and the dx of FIG. 5 is calculated based on the last second axis sensor 6 of FIG. Can be calculated Here, in order to calculate the singer dx, it is calculated from the traveling speed of the vehicle calculated by the first and second axis sensors 4 and 6 of FIG. 4.

The calculation system unit 9 calculates dx = velocity * t when the pulse interval between the second axis sensor 6 of FIG. 4 and the second oblique axis sensor 8 installed diagonally is t. Accordingly, dy may be calculated as in Equation 1.

Dy = tan (45 °) * dx,

Where tan (45 °) = 1

In this case, when the sensor 8 installed at an oblique angle of FIG. 4 is installed at a 45 ° angle, dx = dy is obtained, and if only dx is obtained, the running trajectory of the tire can be directly obtained.

In addition, FIG. 9 is a first and second diagonal shaft detection installed diagonally with the second axis sensor 6 when both the tires of the traveling vehicle in the driving path of (a) and (b) in FIG. The response signals of the sensors 7, 8 are plotted.

Here, as shown in FIG. 8, reference numeral 26 denotes L as the pulse interval of the response waveform between the second axis sensor 6 and the first diagonal axis sensor 7 of FIG. If R is the pulse interval of the response waveform between the sensor 6 and the second oblique axis sensor 8 of Figure 4, the running trajectory of the tie from the reference line can be calculated as shown in equation (2).

Left (driver's seat side) tire track = speed * L,

Right tire track = speed * R

Therefore, the calculation system unit 9 can calculate the roundabout of each axis of the driving vehicle by the formula of Equation 2, and if the distance between two reference lines is d in FIG. 4, the roundabout of each axis = d + LR to be.

On the other hand, the method of calculating the number of tires by the calculation system unit 9 of the method of the present invention in more detail, as shown in FIG. 4, the first and second diagonal axis sensor (7, 8) When a vehicle having the same tire structure as shown in FIG. 7 (15) runs on the sensor, the response waveforms of the left and right sensors are shown as shown in (16) and (17) of FIG.

Here, there are two ways to determine the number of tires from the signal waveform.

first At the vertex  By way

First, the calculation system unit 9 uses a method of counting the number of vertices in the waveforms (16) and (17) of FIG. 7, in which two or more intervals of the vertices are continuously generated with less than 50 cm. If it can be read as a double-wheel structure as shown in equation (3).

Vertex Interval = Travel Speed * Time between Vertices

second Pulse width  Method by measurement

As shown in FIG. 8, the calculation system unit 9 may obtain a signal such as code 22 when the comparator 12 provided therein converts an analog signal into a digital signal. For example, when the tire has a double-wheel structure, two pulses may be continuously generated as shown by reference numeral 22 of FIG. 8, or converted into one long pulse by a threshold level in the comparator 12. At this time, the comparator 12 recognizes one pulse by placing a threshold value when two pulses are generated continuously as shown in (22).

In addition, since the first axis of the vehicle is all single wheels, and the subsequent axes may be single wheels or double wheels, the calculation system unit 9 first reads the tires in pulse widths as shown in Equation 4 when the tires are read by pulse widths. Calculate the ground plane.

Tire ground = running speed * pulse width,

Since the tire ground plane may vary according to the air pressure of the tire, the single-wheel double-wheel classification determines that the wheel that exceeds 150% of the tire width of the first axis is the double-wheel.

(First wheel tire ground plane * 1.5 <after first wheel tire ground plane)

Here, the vehicle model according to the single-wheel / double-wheel structure of the tire is used to distinguish between a small van (including a small passenger car) and a small truck.

On the other hand, the existing vehicle type classification method is to distinguish the vehicle type by simply by the wheelbase, small vans (including small passenger cars) and small trucks, the wheelbase is overlapped with each other, it is impossible to distinguish the car model.

However, the calculation system unit 9 of the present invention has a small van (including a small passenger car) in a two-axis structure, and both the first and second axes have a single-wheel structure. In the case of small trucks, the two axles can be distinguished according to the distinction between the single wheel and the double wheel of the tire because the first axle is mostly a single wheel and the second axle is a double wheel.

As described above, the present invention precisely provides wheel structure information of a traveling vehicle, thereby accurately identifying vehicle information and driving characteristics of a vehicle traveling at high speed on the road, and thereby analyzing traffic for speeding / overloading, traffic analysis, and road design. It provides information and can be very useful when installed on roads where traffic information is collected in real time and precisely.
