Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a method for arresting a vehicle that has driven on the shoulder of a motorway, and the percentage is determined by a predetermined distance 'Ia.
Three sensors are buried at predetermined intervals in important parts of the road shoulder within the range, and each sensor activates a camera installed corresponding to each sensor when a vehicle traveling on the road shoulder is detected. A magnetic recording device that connects to the above-mentioned camera takes time-divided photographs of vehicles traveling on the roadside, including their license plates, as the vehicles move! ! (Magnetic tape and magnetic disk are used as recording media.

[Record one of the L bubble memories for convenience].

This proposal proposes a detection method that allows vehicles driving on the roadside to be arrested using evidence.

[Prior art] Figure 6 shows a running vehicle approach (1) and a road shoulder (2) on a motorway.
It shows.

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

[The problem that the invention attempts 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 detected by human eyes.

However, since this method is manual, it is easily affected by factors that affect human behavior, such as the weather on a given day, and it is difficult to carry out continuous wanderings that are not affected by the weather. do not have.

[BP stage for solving problems]

Three sensors are buried at a predetermined interval in the main part of the road shoulder within a predetermined m [range], and when a vehicle is detected by each sensor, a sensor is installed corresponding to each sensor. An electronic still camera is activated, and the video signal from the camera is recorded by a magnetic recording device K connected to the camera.If two or more sensors detect the departure of a vehicle, an electronic display board placed near the direction of arrival of the vehicle K was requested to display the required information.

[Effect]

An electronic still camera is activated to take pictures of vehicles traveling on the roadside, including their license plate numbers, as the vehicles move, and this is recorded on a magnetic recording device connected to the camera. Display the required information.

〔Example〕

Fig. 1 shows an embodiment of the present invention. In Fig. 1, (1) is a roadway, and (ri is a road shoulder). I
C5A) and (3B) are cars with ``-'', but t<5yh) shows that they are driving near point B, and t<5yh) shows that they are driving near point B. That is, FIG. 2 shows that one car has passed the point B and is headed toward the point C. This is to distinguish between driving on the roadside and parking on the roadside due to a breakdown. (4
(4B)t (4C) are three sensors (for example, metal detectors) buried in important parts of the roadside (here, point A, point B, and point C) within a predetermined distance range. hand,
When a car passes over the sensor, a predetermined detection signal is output to notify the driver of the passing.

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

Oni 5) is the above sensor (4A), (48)e (4C)
This is a control device that outputs 77r control signals based on the signals from the . (6A), (6B), (6
0) are points A and B, respectively.

This is a camera installed corresponding to C, and uses a charge capacitor device (CCD) as the first camera. According to the above camera, the decoding code is II! It is recorded in II 葎1 along with the shooting location and time.

The above three cameras each have a sensor (4A) # (4B
) is related to the detection signal of m(4C). In other words, when a detection signal is generated from the sensor (4 people), the camera (6A
) is activated, and when a detection signal is generated from the sensor (4B), the camera (6B) is activated, and when a detection signal is generated from the sensor (4C), the camera (6c) is activated.

Therefore, if one car or person passes through points B and C, it will be photographed by cameras (6A), (6B) and (6C)K. Therefore, by looking at the photographed image, it is possible to know which car was driving on the shoulder of the road or not. 2 is a magnetic recording device using either a magnetic tape, a magnetic disk, or a magnetic bubble memory as a magnetic recording medium, and is connected to the camera via a control device fC51.

What about figure 2? 1) J1) 1 unit [This shows the main parts of (51) v DA) e (4B) # (4C) is the sensor described above, (aA), (8B).

(8C) is a memory configured by connecting the GteC2'Y or the other side, each corresponding to the above-mentioned sensor.
If an output is generated from (4c) n, the output of gate G2 becomes logical n1''.

Therefore, if the car (3) passes the point person, Memo'J (8A
) becomes n I 1), and then when the car passes point B, gate G2 of memo IJ (8B)
The output of becomes 1■, and if the point C is further passed, the output of the gate G2 of the memory (8C) becomes 1)1. The memory (8A) is reset by the output of the gate G2 of the memory (8B), and the memory (8B) is reset by the output of the gate G2 of the memory (8c). In other words, memory (8B
) is applied to one input of gate G2 of memory IJ (8A) via OR gate (9;), thereby returning the memory (8 people) to its initial state. .On the other hand, memo') (8B) is memory (
8C) is reset by the output of gate G2. a

Provided to gate G2 of memory (8C) via R gate (12). (15A), (15B), (15C)
is a controller provided corresponding to the memory (8A), (8B)l (8C), respectively, and the memory (8A)
, (8B), (8C) operates when each output is received, and the corresponding electronic still camera (6A),
(6B)t (6C) Control in Y order.

Moreover, this controller (15A), (15B), (15
C) is applied to the camera through the date and time signal generated from the clock αe having a calendar function and the input signal of the photographing location input means al, and the I! of the photographed car is supplied to the camera. III! Incorporate the date, time and location of the photograph. The Yu 1 Xu photographed in this way is the controller (15A), (isn), (1s
c) is recorded in a time-division manner on a magnetic recording device (to) connected to. Therefore, if you look at the images recorded on the magnetic recording device and taken with each camera, you can confirm when and where the images were taken.

The first part of the third session shows a specific example of the reset signal generation circuit α3, where ttS is an inverter, (1g is an enclosure for the input signal and output signal, as shown in (a) and (b) of Figure 3 (Bl) A delay circuit whose input signal is logical 1N
Even after the state changes from the state to the state l g 1), the output signal continues in the state 1) 1n for a period of t.

2 is a two-man inversion gate which inputs sound from the output of the inverter t1S and the output of the delay circuit α9.

In such a configuration, when the input of inverter α8 is 1IIn, the output of inverter C1s becomes 1IIn,
Therefore, the output of the delay circuit 9 is also III1). Therefore, the output of gate ■ is u g II. In this state, the memory (8) to which inverter a8 is connected
If the output of gate G2 in C) is 1n, the inverter αδ
The output of If I II changes to -1, and the signal of one input @K ``O'' of gate (2) is given. On the other hand, the output of the delay circuit q is the input signal "1) Even if it changes from 1 to II Q 1), it does not change immediately and continues to be in the state of time tfL:ken I II as described above, and the time period t has elapsed. Later 1)
1)→II OI+. Therefore, the output of gate ■ remains n (I 1) within time, and if both inputs become n g II, then
It becomes 1n like this. This l/→ signal is given as code I to the memory (8C) G2 via the OB gate az in FIG. 2, and resets the memory (8C).

Further, the signal (c) is given to the ItIll image memory (71) as a recording timing signal.In addition, the memory (8C) reset by which signal e→ of the above 8 has the output of the gate G1 as 1)1). The output of the gate G2 becomes III) II, and therefore the output of the reset No. 1 generator a3 (ie, the signal (c)) becomes III II II→1lO1).

That is, the memory (8C) is set when a car passes over the sensor (4C), and after the car passes, it is reset by the output of the reset signal generator a3 and returns to the initial state. Therefore, if you operate the camera (6C)'Y between setting the memo IJ (8C) and resetting it, the sensor (4
You can take pictures of cars passing by C).

This is an OR gate into which the outputs of gates A1 to A3 are input.

In such a circuit configuration, if the outputs of two or more memories are @buried''I II, the output of the OR gate is 1)

I II.

By introducing the outputs of the three sensors into the majority logic circuit and processing them in this manner, 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 @ is the sensor (4A) t (4B)
l (4C) Controls the lighting of the electric display OV, which is installed on the side of the road that is closer to the direction of arrival than the installation position of (4C). (To)

Required characters are displayed on the L-light display board-0 for a certain period of time, and when there are no vehicles running on the roadside, memories M1 to M3 are reset to automatic change.

In other words, if there are continuous vehicles running on the shoulder of the road, the display on the electronic display board will continue, or if one car happens to be driving on the shoulder of the road and there are no similar vehicles following, the display on the electronic display board will continue. It flashes for a certain period of time and then turns off.

Next, the vehicle remains in state 1 until a vehicle traveling on the roadside is detected.

Additionally, the electronic display &@ mentioned above will display a message indicating that vehicles traveling on the roadside are being controlled, to alert following vehicles.

Figure 5 shows an example of installing an electronic display board on a dedicated route, for example, near an exit or in front of a toll gate, and closer to the location of the vehicle than the sensor (4A), (4B)e (4C). Control device K is placed on the side of the road shoulder (2) near the direction of arrival.
151 and the signal from the majority decision @buried circuit Gin included in it, an electronic display board was installed to indicate that roadside weeding/weeding is in progress, and was designed to alert following vehicles to 1kV & wake up. It is.

In other words, if two or more of the three sensors described above detect a vehicle, the display board will display a message indicating that a roadside vehicle enforcement operation is in progress and alert following vehicles. This is what I did.

Note that in FIGS. 5 and 6, the arrows indicate the direction of travel of the vehicle.
