Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a toll ticket issuing device that is installed at a tollgate on a roadway such as an expressway to prevent unauthorized passing due to drivers exchanging or tampering with toll tickets.

In the past, it has been pointed out that the unauthorized use of pass tickets on right-hand II roads such as long-distance expressways has been reported. For example, if driver A is trying to go from Tokyo to Osaka and driver B is trying to go from Osaka to Tokyo via one road, drivers △ and B will indicate that there is a road between Tokyo and Osaka. The drivers meet at a service area, etc., and exchange the pass held by driver Δ with the pass held by driver B.

Driver A then exits the toll road from the toll gate one place before the Osaka toll gate where driver B enters. On the other hand, Driver B exits the toll road from the toll gate one place before the Tokyo toll gate where Triber A entered. In this way, toll charges for toll passageways are fraudulently charged.

In recent years, such fraudulent use of toll tickets has become particularly malicious and sophisticated, and the fairness of toll road use is being obstructed.

For this reason, although various measures have been taken to prevent fraudulent use of toll tickets on toll roads, it is still not possible to prevent this.

An object of the present invention is to provide a toll ticket issuing device that can effectively prevent unauthorized use of toll roads 5P.

The present invention will be explained below with reference to examples. Fig. 1 shows the concept of 11 entrances and their vicinity to which the present invention is applied. 1 is an f'1 road, and a car approaches the tollgate 2 from the direction of the arrow.

On both sides of toll road 10, about 5m before toll gate 2,
A vehicle body detection means 3 is provided.

This vehicle body detection means is composed of a light 13a made of, for example, a Sanskrit diode or the like, and a photoelectric conversion section 31) that receives the light and converts it into an electrical signal. Furthermore, an axle detection means 4 is buried or installed in the road, and is designed to generate a signal when a wheel of a vehicle steps on it.

Therefore, when a car approaches the tollgate 2, the car body detection means 3 outputs a car body detection signal until the car passes through the area of the car body detection means 3.

The axle detection means 4 outputs a signal every time a wheel passes over it. Therefore, it is possible to detect whether the currently passing vehicle has two, three, or more axles.

Reference numeral 5 denotes a television camera provided at the tollgate 2, which images the front of the vehicle near the vehicle body detection means 3 or the axle detection means 4.

FIG. 2 shows a specific example of a toll ticket handed to a driver at a tollgate. A magnetic recording section 7 is provided in a portion of the pass 6. The magnetic recording section 7 may attach a magnetic film made of magnetic powder and a binder to the ticket 6. Alternatively, a ready-made V'TR tape may be adhered or fused to the ticket 6.

The present invention will be explained in detail below using examples. Third

A car enters the entrance of the toll booth, and the body of the car
When entering the operating area of the vehicle body detection means 3, the light emitted from the light source 3a is blocked by the vehicle body.

Therefore, the light emitted from the light source 3a does not enter the photoelectric conversion section 3b. Therefore, while the vehicle body is in the area of the vehicle body detection means 3, a vehicle body detection signal at the level shown at 30 in FIG. 4 is outputted from the photoelectric conversion section 3b.

In this way, the vehicle body detection signal 30 (q) is transmitted to the first 7
It is input to the set terminal of lip flop (hereinafter referred to as FF) 10. The first FF10 is the car body.

When the detection signal 3C rises, the cell i~ is activated, and its Q output is 10
a is at the 11 H++ level, as shown in FIG. This Q output J10a is input to the first monostable multivibrator (hereinafter referred to as MM and Fil') 11. As a result, the first MMII is 1-triggered at the rising edge of the Q output 10a, and outputs the pulse signal 11a.

The output signal 11a of the first MMll is input to the second FF 12, and at the falling edge of the output signal 11a, the second FF
Serve 2. Therefore, as shown in FIG. 4, the signal 12a of the second FFI 2 is
At the same time as the fall of the output signal 11a, the signal becomes "H" level, and the AND gate 13 is closed.

After a while, the vehicle l111 detection signal 4a detected by the axle detection means 4 is input. This m-axis detection signal 4a enters the 20th M1y+14 and is shaped into a desired pulse width. Note that this pulse width of 1 will be explained later. The output signal 141 of the second fVI M 14 passes through the AND gate 13 and is input to the third M M 15 and the pass recording device 1G. Fni: The output signal 13a of the gate 13 is as shown in FIG.

Here, the general structure of the pass recording device 16 will be explained with reference to FIG. In the figure, 31 is a ticket storage tray L/A;
As many as 11 unrecorded passes 6 are stored one on top of the other. , 32
is a delivery board that sends out passes one by one. This feed-out plate 32 has a rectangular shape, for example, and has a protrusion 32a on its negative side that is equal in thickness to one pass ticket.

℃）Usually 1, the 5th
1 as shown in the figure, that is, a part of the bottom of the passable r7 storage tray 31, but when the signal 13a is input, the arrow, 8, It is constructed in such a way that a part of it is oriented in the direction. Therefore, each time the fffir 313a occurs, one pass ticket is sent in the direction of the arrow.

3211 in FIG. 4 indicates the timing at which the number 1'(.) is added.

338.331) lj, pass ticket 6) pick-up roller. 34a is a dry roller that receives power from a drive source (not shown), 37↓b is a pinch roller,
Delivery plate 32 and delivery rolls 33a, 33b
Therefore, the sent out ticket 6a is transferred to these rollers 34a.
And 3413 has the role of sending l\ further to the right of the figure with lυ.

35 is a rotating magnetic head, which receives the sent ticket 6a.
A video signal of the front of the automobile sent from the television camera 5 and various data to be described later are recorded in the magnetic recording section 7 of the camera. 36a and 36b are a drive roller and a pinch roller that sandwich the recorded ticket 6a and further feed it to the right in the figure, and the drive roller 36a, like the roller 34a, is powered by a drive source (not shown). It will be done.

Reference numeral 37 denotes a pressing plate for pressing the card against the rotating magnetic head 35, and presses the card against the rotating magnetic head 35 at the timing when the passing ticket sent from the pass ticket storage tray 31 comes to the position of the rotating magnetic head.

Then, when the time required for the pass 6a to pass the rotating magnetic head has elapsed, the pressing plate 37 moves the rotating magnetic head 3
It is designed to stay away from 5.

Reference numeral 38 denotes a recorded pass ticket storage tray, into which the recorded pass ticket 6b is discharged. The tollgate employee picks up the toll ticket P6b on the tray 38 and hands it to the driver.

The output signals Pr 13a of the anime games 1 to 13 pass through a delay circuit 17 and are input to the reset terminal R of the second F12. If the time is set shorter than the time it takes for the rear wheel to step on this, the second axle detection signal 4a will be
When entering 3, the second FF12 beams 1~
and the AND gate 13 is turned off.

Therefore, the output signal @13a of the AND gate 13 is one signal per vehicle. Therefore, in the above-mentioned pass ticket recording device 16, one pass ticket per vehicle is sent out and recorded.

The fall of the signal @13a described above becomes a trigger signal for the third MM15. Therefore, the third M to 11b- operates if if for a predetermined time starting from the falling point of the signal 13a.
A signal 15a of HjT level is output.

For example, 1/30 x n seconds is appropriate for this time. Note that 11 is 3(n (about 8 is good).

The output signal 15a of the third MM 15 is input to the base of the N P N +- transistor 18, turning it on. This causes relay 19 connected to transistor 18 to
A current flows from the power supply to the relay 19, and this relay 19 is activated.

When one relay is activated, TV camera 5 and recording device @2
0 and the pass ticket recording device @16 is turned on.

Therefore, a video signal of the front of the car captured by the television camera 5 is sent to the recording device 20 and the pass ticket recording device 16 for n frames.

Since the relay contact 19a is mechanically operated, the time when the contact 19a is turned on is slightly delayed from the time when the output 13a of the AND gate 13 falls, as shown in FIG. Here.

The recording device 20 is a device for recording on nine consecutive magnetic recording devices, and is used for recording storage.

The above-mentioned signal F313 a O)-";L down is the 3rd to 4M15 1-return signals as well as various data recorded in the I-key recording section 7 of the pass ticket 6. It also serves as a signal for reading out, for example, the date and time, internet name, operator name, etc. from the data generating means 25.

Next, the contents recorded in 1 on the magnetic recording section 7 of the pass 6 will be explained.

As mentioned above, the falling edge of the signal 13a is caused by the data generation means 2.
fj is used to continuously output data from 5 and turn on the relay contact 19a, and when the relay contact 19d is turned on, it is better to read data from the data generating means 25.
1, so data such as (1) date and time, (2) interchange name, (3) handler's name, etc. are first entered into the recording section 7 of the ticket 6, and then, N frames of the video image of the front of the vehicle described above are recorded.

FIG. 6 shows an example of the data generating means 25 for sending each of the above-mentioned data to the rotating magnetic head 35. here,
The data generating means 25 is formed by a microcomputer. In the figure, 40 is the input capo-1- of the microcomputer,
The output signal 13a of the AND gate 13 in FIG. 3 is input. Furthermore, as will be described later, a signal 39 that is output when a key held by each employee working at the toll booth is inserted into the keyhole is input.

Reference numeral 41 indicates a microcomputer main body, and a signal output from a timer 41a in the microcomputer main body 41 is used as date and time data.

The interchange name is stored in the ROM 41b, and is input into the pass ticket as encoded "numbers", for example. As for the handler name, a number (number) is assigned to all the employees who belong to the toll gate. ROR <-, 4,

The above-mentioned timing for sending each data to the clock 2I and 35 is performed by the rise of the signal ):3a, and when the clock 13a falls on the above-mentioned J-:). After that, the L no. 19 in Fig. 13 becomes in, and the relay contact 19. Closes: J: '73 (Since there is a slight time lag in length, the data will not be recorded in the 1-ki recording section 7 during this lag time.

FIG. 7 is a flowchart for explaining the functions of the microcomputer body 41 mentioned above.

Step S1: Monitor the fall of the signal @13a.

Step S2...If the answer is YES in step S1, the timer 41a outputs data regarding the date and time.

Step S3: Output the inter name.

Step S4: Output the handling signature.

As described above, for drivers using toll roads, the date and time of use, inter name,
You can hand over a ticket that includes data such as your signature and a video image of the front of the car.

When the car passes the vehicle body detection means 3, the vehicle body detection signal 3C falls from the HIT level to the "L° level" as shown in FIG. is triggered by the rising output of the inverter 21, and outputs a pulse output signal 22a with a predetermined pulse width.This output signal 22a is output from the first FF.
Reset terminal of l0 (input this, and the first FF l0 is reset.

In this way, the circuit operation for one car is completed.

Incidentally, by multiplying the Nockles number of the output signal 11a of the first MMll by 1 by the counter 23, the number of passing vehicles can be determined.

Further, by inputting the center axle detection signal whose waveform has been shaped by the third MM 15 into the counter 24 and reading it out using the output signal 22a of the fourth MM 22, it is possible to know the number of axles of the automobile. Note that the counter 24 uses a self-help function when the reading is completed.Furthermore, the output signal 13a of the AND gate 13 is input to the counter 1-1.
Then, you can know the number of tickets issued.

A toll ticket containing various data and a video image of the front of the vehicle is handed to the toll booth at the exit when the driver exits the toll road. The toll gate operator plays back the video image recorded on the magnetic recording section 7 of the toll ticket and compares the video image recorded on the toll ticket with the vehicle that is about to pass through the designated toll gate. .

Next, regarding the equipment installed at the exit toll booth,
This will be explained with reference to FIG. As is clear from the block diagram of FIG. 8, a circuit similar to that provided at the entrance toll gate is used at the exit toll gate. In FIG. 8-C, the same or equivalent parts as in FIG. 3 are given the same reference numerals.

When a car comes to the exit of a toll road and is detected by the vehicle body detection means 3 installed near the toll gate, and furthermore, when the front wheel of the car steps on the axle detection means 4, the relay 19 is activated and its contacts are activated. The operation until 19a is turned on is the same as the operation of the device at the tollgate entrance described above. Now, suppose that the car comes to the exit of the toll gate and the relay contact 19 is turned on, the video signal of the car about to exit the toll road is input to the video synthesis circuit 60, and the video signal is input for several frames. (L/30 x n seconds.

n is an integer) is input to a delay circuit 61 which performs a delay. Therefore, the video signal circulates even after the relay contact 19a is turned off, and the video synthesis circuit 604 continues to output the video signal.

On the other hand, in the ticket recording/reproduction tRG2, the ticket handed out by the driver is deleted, and the video IS record recorded in the magnetic recording section of the ticket is played back. As the pass ticket recording/playback device, a device similar to that shown in FIG. 5 may be used, and the pass ticket may be played back using a rotating magnetic head. In this case, the pass recording/reproducing machine is equipped with a pass ticket insertion slot so that when the pass is inserted, the pass ticket is fed by being sandwiched between the drive roller and the pinch roller.

The signal reproduced by the traffic gR image reproduction circuit 62 is input to the video synthesis circuit 60 as well as to the delay circuit 63 which delays several frames in the same way as the delay circuit 61. The signal input to the delay circuit 63 circulates, and even after the video image of the front of the car recorded on the pass ticket has been reproduced, the video signal is supplied to the image synthesis circuit 60.The output of the image synthesis circuit 60 is It is input to the television receiver 64.

As a result, for example, the upper half of the image screen of the television receiver 64 displays a car that is currently leaving the toll road, and the lower half displays a video image reproduced from the magnetic recording section of the toll ticket. is displayed.

By comparing these two images, a tollgate employee can easily tell whether they are the same or not.

For this reason, if a driver commits fraud by exchanging passes with another driver on a toll road, the two images displayed on the TV screen at the exit of the toll plaza will be different, making it difficult to commit fraud. It is easy to detect that something has happened.

As described above, according to the present invention, the driver enters the toll passage for 8
3 and pass the ticket to kJ[) and 1. L rl appetizer;
You can easily check it at the exit of C. Furthermore, since the data such as the interchange name is input into the magnetic recording part of the pass ticket, it is difficult to tamper with it.Furthermore, according to the present invention, the pass ticket with the data recorded and ``Arp remains C, the accumulation and processing of data and evening becomes easier.
