Description

[Detailed Description of the Invention] [Field of Industrial Application] Is this invention a vehicle that runs on the shoulder of a motorway? Regarding the detection method, its characteristics are that two sensors are buried at a predetermined interval in the main part of the road shoulder within a predetermined distance range,
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 detection that allows criminals to be detected based on evidence.

[Conventional technology]

Figure 5 shows the driving road (1) and shoulder (2) of the road exclusively for own vehicle #I.
).

Car (3) is supposed to drive on the well-known roadway (ll'i), but when roadway (11) becomes congested, traffic violations become noticeable. In other words, it tries to drive on the shoulder of the road and move forward. As the number of cars entering the area increases, they cut into lines of cars connected to the roadway at exits of private roads, making congestion even worse.

[Problem that the invention seeks to solve]

However, in the past, there was no means to automatically detect and detect the sound of vehicles traveling on the shoulder of the road, and the human eye was used to visually recognize and detect vehicles traveling on the shoulder of the road.

However, since this method is manual, it is easily affected by factors that affect human behavior, such as the weather and the two hours of the 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 proposes a method for detecting vehicles running on the roadside without requiring much acquisition.

[Means for solving problems]

In this invention, first and second sensors are provided within a predetermined distance range of the road shoulder, and the first and second sensors are provided in correspondence with each sensor. A second TV camera is installed, and the vehicle detected by the two sensors is photographed by the TV camera, recorded on a videotape recorder or a video disc, and can be played back at any time. An electronic display board was installed near the direction of arrival of the T-vehicles to indicate that a traffic control operation was in progress.

[Effect]

According to this invention, a vehicle traveling on the roadside can be automatically photographed and recorded on a videotape recorder or a video disk, and it is also possible to alert following vehicles.

〔Example〕

FIG. 1 shows an embodiment of the present invention, and FIG. 9 shows a Tl1ti roadway, (2) shows the road shoulder, and (3) shows a car running on the roadway (1) and onto the road shoulder (2).
(3A) and (3B) are the same car, but (3A) is driving near point A, and (3B) is driving near point B. That is, FIG. 1 shows that one car passes through point A and point B1. This is to distinguish between driving on the roadside and parking on the roadside due to a breakdown. (4A), (4B)
is the main part of the road shoulder within a predetermined distance range (here, point A,
Two sensors (e.g. metal detector) buried at point B)
When a car passes over this sensor, a predetermined detection signal is output to notify the driver of the passing. As a result, when a car passes over the sensors at point A and point B, the sensor (4A)
, (4B) are generated in this order. In other words, the relationship between the passage of time and the position of one car can be seen.

(5) is a control device that outputs predetermined control signals based on the signals from the sensors (4A) and (4B).

(6A) and Cl5B) are TV cameras installed corresponding to points A and B, respectively.

The above two TV cameras each have a sensor (4A).

It is related to the detection signal of (4B). In other words, the sensor (
When a detection signal is generated from 4A), the TV camera (6A)
is activated, and when a detection signal is generated from the sensor (4B), the TV camera (6B) is activated. Therefore, if one car passes point A and point B, cameras (6A) and (6B)
It will be photographed by.

Therefore, by looking at the photographed image, it is possible to know which car was driving on the shoulder of the road or not. ()) is a video tape recorder or video disk connected to the above control device via a signal cable SL (ordinary signal line or optical fiber cable), and is installed in a friend's room away from the sensor and TV camera. B. An image including the license plate number of a vehicle traveling on the roadside taken by the above-mentioned TV camera is recorded together with the photographing point and time. Qv is a videotape recorder,
Alternatively, it is connected to the video disc (7) and is a video tape recorder, or a means for timely reproducing images recorded on the video disc (7), such as a 9 display device or a CRT printer.

Figure 2 shows the main parts of the control device (5), (4A
).

(4B) is the sensor described above, (aA), (8B
) are inversion gates, G1. G2t is a cross-connected memory, each corresponding to the above-mentioned sensor, and when an output is generated from the sensors (4A) and (4B), the output of the gate G2 becomes logical %1N.

Therefore, if the car (3) passes point A, the memory (8A
) output of gate G2 becomes %11 92Next, when the car passes point Bi, the output of gate G2 of memory (8B) becomes 1
The memory (8A) is reset by the output of G2. That is, memory (
The output of G2 of 8B) is applied to one input terminal of G1 of memory (8A) through the OR gate (9), thereby bringing the memory (8A) into its initial state. Return to normal. αO is memory (8A), (8
This is a reset switch that gives a reset signal to the OR gate (91, aη) provided corresponding to B).α3 is a memory (8B). The circuit has the configuration shown in FIG. 3, which will be described later, and the reset signal 0 is given to the gate G2 of the memory (8B) via the OR gate aυ, and is also sent to the video tape recorder or video disc (7). It is given as a recording timing signal. (1
4A).

(14B) is a controller provided corresponding to the memories (8A) and (8B), respectively, and the memory (8A).

(8B) Operates depending on the presence or absence of each output, and controls the corresponding camera C6A), (<SR) i.

Further, the controllers (14A) and (14B) incorporate the date, time and location of the photographed car into the photographed image of the car through a signal regarding the date and time generated from a clock having a calendar function and an input signal from the photographed location input means 1119.

Therefore, if you look at the images taken with each camera,
You can check when and where the photo was taken.

Figure 3 shows a specific example of the reset signal generation circuit a3, where αη is an inverter and α barrel is the relationship between the input signal and output signal as shown in (a) and (b) of Figure 3(B). This is a delay circuit configured such that even after the input signal changes from the logical state of %1N to the state of %(31), the output signal remains at the time t.
The function is to continue the state of 11' only. (IIil
This is a two-man inversion gate that inputs the output of the t-inverter collector η and the output of the delay circuit 0→.

In such a configuration, the input of inverter α is %0
1, the output of the inverter aη becomes 111,
Therefore, the output of the delay circuit (LIm is t%11).

Therefore, the output of the gate is %O1. In this state, if the output power of the gate G2 of the memory (8B) connected to the inverter aη becomes p1g, the inverter aη
The signal 101 is given to one input terminal of the gate α9. On the other hand, delay circuit a
Even if the input signal changes from %11 to %61, the output of II does not change immediately, but continues in the state 111 for time t as described above, and changes from %11 to %01 after two hours t have elapsed.

Therefore, the output of gate a9 is within %O
If the two inputs both become %Ol, it becomes %1' as shown in P→031 in FIG. 3. This signal (c) is applied to the gate G2 via the OR gate I in FIG. 2, and resets the memory (8B)'t-. Also e→
The signal is output from a video tape recorder or video disc (
7) gives a recording timing signal. Note that the above signal (
The memory (8B) reset by c) is the gate G
The output of 1 is %11. The output of the reset signal generator (IX5) becomes 101, and therefore the output of the reset signal generator (IX5 (ie, signal t31) becomes East 11 → East t31.

That is, the memory (8B) is reset by the car passing over the sensor (4B), and after the car passes, it is reset by the output of the reset signal generator and returns to the initial state. Therefore, if the camera (6B) is activated between the time when the memory (8B) is set and the time when the memory (8B) is reset, it is possible to take a photograph of a car that has passed the sensor (4B).

Figure 4 shows functions added to the embodiment shown in Figure 1.
For example, near the exit of a private road or in front of a toll gate, and in contrast to the installation position of the sensors (4A) and (4B), the control device (5) is placed on the side of the road shoulder (2) in the direction from which the vehicle is coming.
) An electronic display board w2 is provided to indicate that roadside vehicle enforcement is in progress using a signal from the roadside vehicle, thereby alerting following vehicles.

In other words, on the condition that a vehicle detection signal is generated from either or both of the sensors (4A) and (4B), the display board (■) indicates that roadside vehicle enforcement is in progress, and the following It is designed to alert people to cars.

Note that the arrows in FIGS. 4 and 5 both indicate the direction of travel of the vehicle.
