Description

[Detailed Description of the Invention] This invention is used at toll gates on expressways, etc., to prevent illegal passage due to drivers changing or tampering with their passes. Regarding toll road passes.

2. Description of the Related Art In the past, it has been pointed out that there has been fraudulent use of passes on expressways such as long-distance expressways. For example, if driver A fJ < is trying to go from Tokyo to Osaka via a toll road, and driver B is trying to go from Osaka to Tokyo, then drivers A and B may indicate that there is a road between Tokyo and Osaka. 1. The drivers meet at a no-history area, etc., and exchange the pass held by driver A with the pass held by driver B there.

Then, Driver A exits the toll road from the toll gate one place before the Osaka toll gate where Driver B entered. On the other hand, Driver B exits the toll road from the toll gate one place before the Tokyo toll gate where the driver entered. In this way, toll road tolls 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 road ticket that can effectively prevent unauthorized use of the toll ticket on the toll road.

The present invention will be explained below by way of examples. FIG. 1 is a conceptual diagram of the toll gate entrance and its vicinity where the toll ticket of the present invention is used. 1 is a toll road, and a car approaches the toll gate 2 from the direction of the arrow. In front of tollgate 2,
Vehicle body detection means 3 are provided on both sides of the toll road 1 at a distance of about 5 m.

This vehicle body detection means is composed of a light source 3a made of, for example, a Sanskrit diode or the like, and a photoelectric conversion section 311 that receives the light and converts it into an electrical signal. In addition, an axle detection means 4 is buried or installed on the road, and the axle detection means 4 outputs a signal when a wheel of an automobile steps on the axle detection means 4.

Therefore, when the automobile approaches the tollgate 2, the vehicle body detection means 3 outputs a vehicle body detection signal until the vehicle passes through the area of the vehicle body detection means 3. Further, the axle detection means 4 is
It 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 an embodiment of the present invention, in which a magnetic recording section 7 is interposed in a portion of the '0 ticket 6, for example, the lower half of the ticket. The magnetic recording section 7 may attach a magnetic film made of magnetic powder and a binder to the ticket 6. In addition, ready-made V
The TR tape may be cut to a predetermined length and adhered or fused to the pass 6.

In the magnetic recording section 7 of the pass 6, a device described later at the entrance toll gate records data such as the poem, the handler's name, the interchange name, etc., and the front of the car in which the driver to whom the pass is handed is riding. Ru. Since this recording is magnetic recording, even if a malicious driver attempts to falsify the interface name, he or she will not be able to do so.

In addition, if you exchange your toll ticket with another driver's, the magnetic recording part of the toll ticket will be played back at the exit toll booth, and you will be able to connect with the vehicle recorded in the toll ticket and the vehicle that is about to leave the toll road. Since the vehicle is checked to see if it is the same as the vehicle, fraud can easily be exposed.

Next, the device according to the present invention for recording data such as poems, handler name, interchange name, etc., and a video signal of the front of the vehicle on the magnetic recording section of the pass ticket will be explained in detail with reference to FIGS. 3 and 4. Ru. FIG. 3 is a block diagram, and FIG. 4 shows a term chart of the main signals.

When a car enters the tollgate entrance, the body of the car is
When the vehicle body detection means 3 is activated, 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 31). Therefore, while the vehicle body is in the area of the vehicle body detection means 3, a vehicle body detection signal of "H" level as shown at 30 in FIG. 4 is outputted from the photoelectric conversion section 3b.

The vehicle body detection signal 3c thus obtained is input to a set terminal of a first flip-flop (hereinafter abbreviated as FF?1) 10. The first FF10 is set at the rising edge of the vehicle body detection signal 3C, and its Q output J10a becomes a bell as shown in FIG. Monostable multivibration unit (hereinafter referred to as MM
(abbreviated as )11. This allows the first MMl

The output signal 11a of the first MMll is input to the second FF12, and the second FF12 is set at the fall of the output signal 11a. Therefore, as shown in Figure 4,
The signal 12a of the second FFI 2 becomes the II HII level in synchronization with the fall of the output signal 11a of the first MMll, and the AND gate 13 is opened.

After a while, an axle detection signal 4a detected by the axle detection means 4 is input. This axle detection signal 4a
enters the second M~114 and is shaped into a desired pulse width. Note that this pulse width will be described later. second M
The output signal 14a of the M14 passes through the game 1-13 and is input to the third MM15 and the pass recording device 1G. The output signal 13a of the AND gate 13 becomes as shown in FIG.

Here, a schematic combination of the pass ticket recording device 1G will be explained with reference to FIG. In the figure, reference numeral 31 denotes a ticket storage tray, in which a large number of unrecorded tickets 6 are stored one on top of the other. Reference numeral 32 is a feed-out board that feeds out the 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 to the thickness of one pass ticket.

Normally, it is biased by the spring 33 and is in the position shown in FIG. It is configured to move in the direction of the arrow by a solenoid or the like that is energized at the rising edge. Therefore, signal 13
Each time a is fired, one ticket is sent in the direction of the arrow.

32I) in FIG. 4 shows the timing at which this solenoid is activated.

33a and 33b are rollers for feeding out the pass 6.

34a is a drive roller that receives power from a drive source (not shown); 34b is a pinch roller; a feed-out plate 32 and feed-out rolls 33a, 3311J;
b has the role of sending it further to the right in the figure with the /v.

35 is a rotating magnetic head, which receives the sent pass 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 further send the recorded ticket 6a to the right in the figure using scissors/v, and the drive roller 36a, like the roller 34a, receives power from a drive source (not shown). is given.

37 is a pressing plate for pressing the card against the rotating magnetic head 35, and the card sent from the storage tray 31 rotates [! When the card reaches the vertical head position, press the card against the rotating cylinder 35.

Then, after the time required for the passing W 6 a to pass the rotating magnetic head, the four plates 37 are moved away from the rotating magnetic head 35.

Reference numeral 38 indicates recorded ticket storage 1 to ray, and the recorded ticket 61] is discharged here. The employee at the toll gate picks up the toll ticket 6b from 1 to 38 and hands it to the driver.

The output signal 138 of the Ando Goo 1-13 is sent to the delay circuit 17
The signal is then input to the reset 1 to terminal R of the second FF 12.

By setting the delay time of this delay circuit '17 to be shorter than the time from when the front wheel steps on the axle detection means 4 until when the rear wheel steps on it (15<, the second axle detection signal 4a is -13, the second FF 12 is turned off 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 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 MM 15 receives the signal 13
11 H1 for a predetermined time starting from the falling point of a
A signal 15a of the level signal is output.

For example, this time is 1. /30 x n seconds is appropriate. Note that 1, n is preferably about 3i11≦8.

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

When the relay 19 is activated, the television camera 5 and the recording device 2
0 and the pass ticket recording device R16 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 one frame.

Note that since the relay contact 19a operates mechanically, the time when this 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 continuous aerobic data, and is used for record storage.

The fall of the signal 13a described above is caused by the third M as described above.
It serves as a trigger signal for M15, and also serves as a signal for reading out various data recorded in the magnetic recording section 7 of the pass 6, such as date and time, inter name, handler name, etc., from the data generating means 25, which will be described later. .

Next, the contents stored in 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.
5 and to turn on the relay contact 1a, and since the data reading from the data generating means 25 is earlier than the time when the relay contact 19a is turned on, the passing ticket 6 First, data such as (1) date and time, ('2J inter name, (3) operator name, etc.) are input into the magnetic recording section 7, and then n frames of the video image of the front of the car are recorded. Ru.

FIG. M6 shows an example of the data generating means 25 for sending each of the above-mentioned data to the rotary magnetic head 35. here,
The data generating means 25 is formed by a microcontroller. In the figure, 4o is the input port of the microcomputer,
The output signal @13a of the AND gate 13 in FIG. 3 is input. Furthermore, as will be described later, when a key held by an employee working at a toll booth is inserted into a keyhole, the message outputted is a message sent to the person.

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. The handler name is a number (number?
) and store this number in the ROM 41b.

When the employee starts working, a signal 39 is activated depending on the type of cape inserted into the keyhole.
The number of the slave ff1M that is being worked on is ROM41b.
is read from. This number is sent to the rotating magnetic head 35 through the output port 42.

The above-mentioned timing for sending each data to the rotating Fp head 35 is performed at the falling edge of the signal 13a. As mentioned above, after the signal 13a falls, the third
Since there is a slight lag time between when the relay 19 shown in the figure turns on and the relay contact 19a closes, the data is recorded in the pass ticket magnetic 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.

5 Step S3: Output the inter name.

Step S4: Output the handler's name.

As described above, drivers who use toll roads will receive data such as the date and time of use, the name of the interchange, and the name of the handler on the magnetically recorded part of the toll ticket. You can be handed a ticket with a video image of the front of the sash.

When the vehicle passes the vehicle body detection means 3, the vehicle body detection signal 3C falls from the HII level to the "L" level, as shown in FIG. Driro y point C is triggered by the rising output of the inverter 21, and outputs a pulse output signal F322a with a predetermined pulse width.This output signal 22a is input to the rehit terminal of the first [2F10, F of
[10 pieces are 1~.

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

Note that by counting the number of pulses of the output signal 11a of the 10th MIv 111 by the counter 23, the number of passing vehicles can be determined.

Also, input the axle detection signal waveform-shaped by the third MM 15 to the counter 24! After ζ, front 81st 4th MM22
By reading out the output signal 22a1-, it is possible to know the number of axles of the automobile. Note that the counter 24 used is one that is automatically reset to 1 when reading is completed. Furthermore, Andoo! - By counting the output signal 13a of No. 13, you can know the number of issued passes.

A single ticket with each inserted data and video image of the front of the vehicle recorded is handed to the toll booth at the exit when the driver or rover exits the toll road. The toll plaza worker 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 currently passing through the toll plaza. Now.

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

When the automobile comes to the exit of the 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 automobile steps on the upper axis detection means 4, the relay 19 is activated. The operation until the contact 19aIJ< turns on is as follows:
The operation is the same as the above-mentioned 1:1 neck-wearing operation when entering the tollgate.If C1 automatic width reaches the exit of the tollgate and relay contact 19a is turned on, toll j@ The video signal of the car about to leave the road is sent to the video synthesis circuit 6.
0 and several frame periods (1/30
Delay circuit 61 that performs a delay of x n seconds; 1) is an integer)
Input to cover. Therefore, the video signal is transferred to relay contact 19
Even after signal a is turned off, it continues to circulate and output video signals to the video synthesis circuit 60.

On the other hand, in the pass ticket recording/reproducing section 17162, the pass ticket handed out by the driver is set, and the video signal recorded in the magnetic recording section of the pass ticket is played back. To record and reproduce the pass ticket, a device similar to that shown in FIG. 5 may be used, and the pass ticket may be reproduced using a rotating magnetic head. In this case, the pass recording and reproducing machine is provided with a pass ticket insertion slot so that when the pass is inserted, the pass is automatically sandwiched between the drive roller and the pinch roller and fed.

The signal reproduced by the pass ticket recording/reproducing device 62 is input to the video synthesis circuit 60 and also to the delay circuit 63 which, like the delay circuit 61, delays several frames. 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 finished playing, the video
The signal is supplied to a video synthesis circuit 60. Video synthesis circuit 60
The output 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.

Therefore, 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 gate will be different. It is possible to easily detect fraud.

As described above, according to the toll ticket of the present invention, when a driver exchanges a toll ticket in a toll passageway, the driver can easily check the toll ticket at the exit of the toll gate. Additionally, since data such as the interchange name is entered into the magnetic recording section of the ticket, it is less likely to be tampered with. Furthermore, according to the present invention, the data recorded on the ticket and the tape for storage remain, making it easier to store and process the data.
