Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a method for detecting a vehicle that has driven on the shoulder of a motorway, and is characterized by the following: bury sensors at predetermined intervals,
When a vehicle running on the road shoulder is detected by each sensor, a camera installed corresponding to each sensor is activated to take pictures of the vehicle running on the road shoulder, including the license plate number, as the vehicle moves. This paper proposes a method of exposing criminals that can be detected in an evidence room.

[Conventional technology]

Figure 6 shows the roadway (1) and shoulder (2) of the motorway.
It shows.

As is well known, the car (3) is supposed to drive on the road (1), but when the road (11) becomes congested, traffic violations become noticeable. In other words, cars try to move forward by driving on the shoulder of the road. As the number of cars increases, they cut into lines of cars connected to the roadway at exits from private roads, making congestion even worse.

[Problem that the invention seeks to solve]

However, in the past, there was no means for automatically detecting and arresting vehicles traveling on the shoulder of the road, and vehicles traveling on the shoulder of the road were visually recognized and arrested using the human eye.

However, since this method is manual,
It is easy to be affected by factors that influence human behavior, such as the weather that day, and it is not easy to carry out continuous detection that is not affected by the weather.

This invention improves these conventional problems.

This project proposes a method for detecting vehicles driving on the roadside without requiring much human effort.

[Means for solving problems]

In this invention, the first degree, the second degree, and the second degree are located within a predetermined distance range of the road shoulder.
A third sensor is provided, and a third sensor is provided corresponding to the first sensor. Second. A third TV camera was installed.

Vehicles detected by any two of the three sensors are photographed with a TV camera and saved on an optical disc for playback at any time.

Furthermore, a display board provided closer to the direction of travel of the vehicle than the sensor installation position is configured to indicate that the vehicle traveling on the road shoulder should return to the road.

[For production]

According to this invention, when any two of the three sensors detect a vehicle traveling on the roadside, the camera corresponding to the sensor photographs the vehicle and files it on an optical disk, and the progress of the vehicle is roughly determined from the installation position of the sensor. An electronic display board installed near the road will indicate that vehicles driving on the road shoulder should return to the road.

〔Example〕

Fig. 1 shows an embodiment of the present invention. In Fig. 1, +11 indicates the roadway, (2) indicates the road shoulder, and (3) indicates a vehicle running protruding from the roadway (1) onto the road shoulder (2). , (
3A) and (3B) are the same car, but (5A) is at point A.
(3B) indicates that the vehicle is traveling near point B. In other words, in Figure 1, 1
The figure shows that a car has passed through points A and B, and is heading toward point C. This is to distinguish between driving on the roadside and parking on the roadside due to a breakdown. (4A
), (4B), and (4G) are three sensors (for example, metal detectors) buried in important parts of the road shoulder (here, point A, point B, and point C) within a predetermined distance range, When a car passes over this sensor, it outputs a predetermined detection signal to notify you of this.

As a result, when a car passes over the sensors at point A, point B, and point C, sensors (4A), (4B), (4c)
) Detection signals are generated in the following order. In other words, the relationship between the passage of time and the position of one car can be seen.

(5) is the above sensor (4A), (4B)l (4C)
This is a control device that outputs predetermined control signals etc. based on signals from. (6A), (6B), and C6C) are TV cameras installed corresponding to points A, B, and C, respectively.

The above three TV cameras each have a sensor (4A) 1 (
4B) and (4C). That is, when a detection signal is generated from the sensor (4A), the TV camera (6A) is activated, when a detection signal is generated from the sensor (4B), the TV camera (6B) is activated, and when a detection signal is generated from the sensor (4C). When it happens, use a TV camera (6C)
) is activated. Therefore, one car is at point A.

If you pass point B and point C, camera C6A), (6B
) and will be photographed by (6C). Therefore, by looking at the photographed image, it is possible to know which car was driving on the shoulder of the road or not. (7) is an optical disk connected to the control device (5) via a signal cable SL (ordinary signal line or optical fiber cable), which captures images including the license plate numbers of roadside vehicles taken by the camera at the shooting point. , and record it along with the shooting time. (to) is connected to an optical disk (7), and is a means for reproducing images stored on this optical disk (7) in a timely manner.
It is a display device or a printer.

Figure 2 shows the main parts of the control device (5), (4A
)1(4B), (4C) are the above-mentioned sensors, (8
A), (8B), and (8C) are respectively inverted games) G
This is a memory configured by cross-connecting ls G2, and each corresponds to the above-mentioned sensors, such as sensor (4A),
When outputs are generated from (4B) and (4G), the output of gate G2 becomes logical "1".

Therefore, if car (3) passes point A, note ") (8A
), the output of gate G2 becomes “1” and the car moves to point B.
Note if you pass! If the output of gate G2 of J (8B) becomes “1” and it further passes point C, memo! J (
The output of gate G2 of 8C) becomes 1". And memo'
) Memo U (8A) is reset by the output of gate G2 of (8B), and Memo! The memory (8B) is reset by the output of gate G2 of J (BC). That is, memory (
The output of gate G2 of memory U (8A) is applied to one input terminal of gate G2 of memory U (8A) via OR gate (9), thereby returning memory (8A) to its initial state. . On the other hand, memory (8B) is a memo! J
(8G) is reset by the output of gate G2.

(1G is a reset switch that gives a reset signal to the OR gate (9), αυ, az provided corresponding to the memory (8A), (8B), (8G). ) A reset signal generation circuit that resets after G2 generates an output, and includes a third
The configuration is as shown in the figure, and the reset signal I is an OR gate l.
The signal is applied to the gate G2 of the memo 'J (8C) through the signal cable SL, and is also applied as a recording timing signal to the optical disc (7) through the signal cable SL. (15A),
(1513), (15C) is memory (8A), (
8B) A controller provided corresponding to 1 (8C), which operates when there is an output from each of the memories (8A), (8B), and (8G), and controls the corresponding camera (
6A).

(6B) and C6G) are controlled in order.

Moreover, this controller (15A), (15B), (15
C) passes through the date and time signals generated from the clock t1[9 having a calendar function and the input signal from the photographing location input means αD.

Incorporate the date, time and location of the photographed car image. Therefore, if you look at the images taken with each camera,
You can check when and where the photo was taken.

Figure 3 tAl shows a specific example of the reset signal generation circuit αJ, where US is an inverter and α9 has the relationship between the input signal and output signal as shown in (A) and (B) in Figure 3 tBl. A delay circuit whose input signal is a logical “1”
The function is such that the output signal continues to be in the "1" state for a period of time even after changing from the "" state to the "0" state. It is a human-powered reversal gate.

In such a configuration, the input to the inverter α ladder is 10
'', the output of the inverter σl is 1, and therefore the output of the delay circuit 09 is also 1.

Therefore, the output of gate (2) is "O". Memory (8C) to which inverter 11B is connected in the state shown in Part B
When the output of the gate G2 becomes 1', the output of the inverter (11 changes from "1" to "0", and a signal of "0" is given to one input terminal of the gate G2. Even if the input signal changes from "1" to "0", the output does not change immediately; as described above, the output continues to be "1" for time t, and changes from "1" to "10" after nine hours t have elapsed. Therefore, the output of gate ■ remains 0 within a certain period of time, and when both inputs become 0, it becomes 1 as shown in kX+ in tBl in Figure 3. This f=11 signal is sent as a reset signal α via OR gate α2 in Figure 2)
(8C) is given to the gate G2 of the memo IJ (8C)
Reset. Also, the signal of V\) is the image memory (7)
as a recording timing signal. Note that the above signal (
In the memo IJ (8C) reset by c), the output of gate G1 becomes "1" and the output of gate G2 becomes "0", so the output of reset signal generator Q3 (that is, signal (c)) becomes "1". ”→“θ”. That is, the memory (8C) is set by the car passing over the sensor (4C), and after the car passes, the reset signal generator α
It is reset by the output of J and returns to the initial state.

Therefore, if the camera (6C) is activated between the time when the memory (8C) is set and the time when it is reset, it is possible to take a photograph of a car that has passed the sensor (4C).

Figure 4 shows the majority logic circuit (l) included in the control device (5).
This is an out of 3 circuit 1υ, which is a characteristic feature of the present invention. Sl, S2. Ss is the output of memories (8A), (8B), and (8G) in FIG.

A1-A3 are AND gates, the output of memory M1 is input to gates A1 and A3, the output of memory IJM2 is input to gates A1 and A2, and the output of memory M3 is input to gates A2 and A3. OR is an OR gate into which the outputs of the first AND gates A1 to A5 are input.

In such a circuit configuration, if the outputs of two or more memories are logical "1", the output of the OR gate becomes "1". In contrast, none of the sensors detected a car, and only one sensor detected a car. OR if
The output of the gate is not "bi" but "10".

By introducing the outputs of the three sensors into the majority logic circuit and processing them in this way, it is possible to clearly distinguish between roadside parking and roadside driving. ■ is a control circuit with a reset timer, and the output of this circuit @ outputs the sensor (4A) I (4B).

In other words, if there are continuous vehicles running on the shoulder of the road, the display on the electronic display board will continue, but if one car happens to drive on the shoulder of the road and there are no similar vehicles following, the display on the electronic display board will remain on for a certain period of time. After blinking, the light goes out and continues in that state until the next vehicle is detected on the roadside.

Note that the above-mentioned electronic display board (to) displays a warning for vehicles traveling on the road shoulder to return to the road.
