Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a toll collection device for a toll road.

[Prior Art] As a current toll collection system for toll roads, a toll ticket issuing method is generally adopted. FIG. 6 is a diagram for explaining this system, and in front of the booth 1 at the population side and exit side tollgates is a vehicle detection device for detecting the entry of a vehicle 3 traveling on the tollgate entry lane 2. 4, a pair of vehicle separators 5, 5 that separate passing vehicles 3 one by one, and a number of axles and wheels that detect the number of axles and wheels of the vehicle 3 when the vehicle separators 5, 5 are turned on. A lane control device 7 in the booth 1 controls the operation of the ticket processing machine 8 in response to a vehicle detection signal from the vehicle detection device 4.

That is, the ticket processing machine 8 at the entrance side toll gate is controlled to issue a ticket 9 on which entrance side toll gate information and vehicle type information are recorded, and the ticket processing machine 8 at the exit side toll gate is controlled to issue the ticket 9 on which the entrance side toll gate information and vehicle type information are recorded. The toll fee is calculated based on various information recorded on the ticket 9. Therefore, the toll collector at the entrance side toll gate hands the toll ticket 9 issued from the toll ticket processing machine 8 to the user of the passing vehicle 3, and the toll collector at the exit side toll gate hands the toll ticket 9 issued from the toll ticket processor 8 from the user. The ticket processing machine 8
The toll collection process ends by receiving the calculated toll from the user.

However, in the conventional toll collection system described above, passing vehicles must always stop at toll gates, making it difficult to alleviate traffic congestion on toll roads with heavy traffic.

In order to achieve non-stopping of vehicles at tollgates, AV
I (Automatic Vehicle
It is possible to introduce an identification system. This AVI system installs on-road devices at the entrances and exits of toll roads or specific points within toll roads, and also installs on-vehicle devices on passing vehicles.
By providing a generation function, it is possible to know from which toll gate a passing vehicle enters and from which toll gate exits, and this system is used to calculate the toll of the vehicle and pay it separately. Once processed, it will be possible to avoid stopping at tollgates.

By the way, when the AVI system is introduced into the above-mentioned ticket issuing system, the items to be recorded on the ticket, that is, the entrance toll gate information and vehicle type information must be input into the on-vehicle device.

To do this, it is necessary to determine the type of vehicle passing by and to transmit this vehicle type information together with population toll information to the on-vehicle device using wireless communication means.

[Problems to be Solved by the Invention] However, in the current toll collection system, an automatic vehicle type identification device is not installed, and the actual situation is that the toll collector relies on visual identification. For this reason, if an AVI system were to be introduced into the conventional ticket issuing system, toll collectors would have to visually identify the vehicle type of passing vehicles and quickly determine whether or not the incoming vehicle is equipped with an on-board device. , vehicle type information and entrance toll gate information will be sent to vehicles equipped with the vehicle using wireless communication means at appropriate timings, and toll tickets will be issued or processed as before for vehicles without the vehicle. It is necessary to do this and collect tolls in cash. Therefore, not only does the burden on the toll collector increase, but it is also difficult to determine the timing for transmitting vehicle type information and the like to the on-vehicle device.

Therefore, the present invention makes it possible to easily determine whether or not a vehicle passing on a toll road is equipped with an on-vehicle device, and performs normal toll collection for vehicles not equipped with an on-vehicle device, while collecting a predetermined toll for vehicles equipped with an on-board device. To provide a toll collection device for a toll road, which enables non-stop driving at toll plazas by transmitting vehicle type information to an on-vehicle device at the right time, eliminates traffic congestion, and reduces the labor of toll collectors. The purpose is to

[Means for solving the problems] In order to solve the above problems and achieve the purpose, the present invention has the following features:

3 through an address bus AB and a data bus DB,
Signals are exchanged with the register section 63 or each of the interface sections 68 to 72 in response to an execution command C36 from the arithmetic control section 62.

On the other hand, the program storage unit (ROM) 67 stores a program for controlling the system and data at the entrance/exit of the toll gate. In addition, the data storage unit (RA
M) 73 is used to temporarily store signals from each device under the control of the central processing unit 61 to perform calculation control and to store data for sending calculation results to each device.

Note that the central processing unit 6] and data storage unit 73 are connected to each of the interface units 68 to 72 by address bus AB, data bus DB, and interrupt lines IRI to IR5. Further, the control signal line CSx is for controlling the data transfer direction of both the calculation control section 62 and the data storage section 73.

Next, as an operation of the apparatus of this embodiment configured as described above, first, a case where the vehicle 3 is not equipped with the on-vehicle device 12 will be described. When a vehicle 3 that is not equipped with the on-vehicle device 12 approaches the vehicle detection device 4 installed just before the toll gate,
While the vehicle separators 5 and 5 are outputting vehicle detection signals, the wheel number/wheel number detector 6 detects the number of wheels and the number of wheels of the vehicle 3, and based on this, the vehicle code signal shown in the table below is generated. generated.

and the vehicle code signal "-" is transmitted to the vehicle separator 5.5.
The signal is sent to the vehicle detection device interface section 69 of the lane control device 7 at a timing corresponding to the vehicle detection signal from the lane control device 7, and is further temporarily stored in the data storage section 73 via the data bus DB in response to the interrupt control signal IR3 and the control signal C8y.

After that, when the vehicle 3 approaches the toll gate booth 1, the toll collector visually determines the vehicle type (for example, large car, regular car, small car), and presses the vehicle type selection button provided on the ticket processing machine 8. Press the corresponding button (not shown).

Then, the vehicle type signal corresponding to the suppression button and the vehicle code signal stored in the data storage section 73 are read out by the action of the central processing section 61, address bus AB, data bus DB, and control signal lines CSx and C3y. It is sent to the ticket processing machine 8 via the ticket processing machine interface section 68. Therefore, the toll ticket 9 has vehicle type information, vehicle code information, and entrance toll gate information magnetically recorded and printed.
is issued, and the toll collector hands the toll ticket 9 to the vehicle user. Thus, the work at the toll gate entrance is completed.

On the other hand, the toll collector at the exit of the toll gate applies the ticket 9 received from the user of the vehicle 3 to the ticket processing machine 8. Then, the toll fee is calculated from the vehicle type information and the entrance toll gate information magnetically recorded on the toll ticket 9. Further, the vehicle code signal determined by the vehicle detection device 4 and the vehicle code signal magnetically recorded on the ticket 9 are compared and verified. If the two vehicle code signals match, the toll collector receives the toll from the vehicle user, thereby completing the toll collection task.

Next, a case where the vehicle 3 carrying the on-vehicle device 12 passes through will be described. When the user of the vehicle 3 approaches the installation position of the vehicle detection device 4 at the toll gate, he or she directs the on-vehicle device 12 to face the first on-road device 11 . Then,
A carrier signal is outputted from the ID number storage section 37 shown in FIG. 3 to the signal transmission circuit 36, modulated and amplified, and then transmitted from the transmission/reception antenna 23. This carrier signal is received by the receiving antenna 41 shown in FIG. 4(a),
It is amplified, demodulated, and decoded.

At this time, since the vehicle detection signal is transmitted from the vehicle detection device 4, the carrier signal from the on-vehicle device 12 is sent from the AND circuit 45 to the lane control device 7, and the interrupt control signal I R4, control signal C8y and Address bus AB
, are temporarily stored in the data storage section 73 by the action of the data bus DB.

Thereafter, when the vehicle approaches the installation position of the second roadside machine 13, the toll collector visually determines the vehicle type and presses the corresponding vehicle type selection button on the ticket processing machine 8. Then, the vehicle type signal is manually input into the lane control device 7 via the ticket processing machine interface section 68, and this vehicle type signal is temporarily stored in the data storage section 73.

On the other hand, an ID number signal is outputted from the ID number storage section 37 of the vehicle-mounted device 12 to the signal transmission circuit 36, modulated and amplified, and then transmitted from the transmission/reception antenna 23. This ID
The number signal is received by the transmitting/receiving antenna 41 shown in FIG.
It is transmitted to the lane control device 7 via. Lane control device 7
Then, the above ID number signal passes through the second on-road device interface section 72, and is then sent to the interrupt control signal IR2 and the control signal line C8y.
The data is stored in the data storage section 73 by the actions of the address bus AB and the data bus DB.

As a result, after the central processing unit 61 determines that the carrier signal of the vehicle 3 is stored in the data storage unit 73, the vehicle type signal information and entrance toll gate information stored in the data storage unit 73 are determined. is given to the second on-road device interface unit 72 by the action of the control signal line CSx, address bus AB, data bus DB, and control signal line C8y, and is further transmitted from the transmitting/receiving antenna 46 of the second road device 13 to the on-vehicle device 12. sent towards. However,
In the on-vehicle device 12, an information signal indicating vehicle type signal information and entrance toll gate information received by a transmitting/receiving antenna 23 is amplified by an amplifier circuit 31 operated by a transmitting/receiving switching circuit 40, and is further amplified by a demodulating circuit 32. After being decoded by the decoder circuit 33, it is temporarily stored in the storage circuit 34. At this time, the buzzer 35 outputs a sound and the display unit 22 displays the received information.

Note that at the time when the carrier signal is sent via the first roadside device 11, a signal to stop issuing tickets is sent from the lane control device 7 to the ticket processing machine 8, and the vehicle type selection Even if the button is pressed, no ticket will be issued.

After that, the vehicle 3 passes through the tollgate, and the start detection device 1
When the vehicle 3 passes the vehicle separator 15.15 at 4, forward passage of the vehicle 3 is detected by the action of the separator 15.15 and the axle number detector 16, and a vehicle detection signal is transmitted via the start detection device interface section 70. data storage unit 68 by the action of the central processing unit 61.
The memory contents of will be erased. Thus, the work at the toll gate entrance is completed.

On the other hand, at the toll gate exit, the toll gate information and vehicle type information stored in the storage circuit 34 of the on-vehicle device 12 and the ID number information stored in the IDi number storage section 37 are transferred to, for example, the second road device 13. The toll is transmitted, the lane control device 7 calculates and stores the toll, and the toll is separately paid.

Note that when a mixture of vehicles equipped with the on-vehicle device 12 and vehicles without the on-board device 12 enter the toll plaza consecutively, the vehicle detection device 4 and the first road device 11 and the second road device 13 Although there are a plurality of vehicles in between, the lane control device 7 sequentially stores vehicles equipped with the on-vehicle device 12 and vehicles not equipped with the vehicle-mounted device 12.
In addition, since it is automatically determined whether the vehicle is a vehicle that requires the issuance of a pass ticket, that is, a vehicle that is not equipped with an on-board device, or a vehicle that does not need to be issued a pass ticket, that is, a vehicle that is equipped with an on-board device, the toll collector can The vehicle model selection button may be mechanically suppressed by sequentially determining the model of the vehicle approaching the second road vehicle 13.

Therefore, according to the device of this embodiment, a road user with a criminal record can drive through a toll gate without stopping by installing the on-vehicle unit 12 of the AVI system. Furthermore, the toll collector does not need to issue a pass 9 to a vehicle equipped with the on-vehicle device 12. Therefore, toll collection operations can be facilitated, and traffic congestion at toll gates with heavy traffic can be expected to be alleviated.

In addition, AVI is available in a format that does not change the current ticket issuance method.
system can be introduced. That is, by visually determining the vehicle type and manually inputting the vehicle type information, the toll collector H can transmit a vehicle type signal to the on-vehicle device 12 at a predetermined timing.

Therefore, there is no need to install a vehicle type discrimination device with a complicated structure, and the present invention can be realized at low cost. Furthermore, the toll collector only needs to visually determine the type of vehicle, whether it is a ticket-issuing vehicle or a vehicle equipped with an on-board device, and press the vehicle type selection button on the ticket processing machine 7. Since there is no need to judge whether the vehicle is equipped with the toll or not, there is no confusion in toll collection work, and labor can be reduced.

[Effects of the Invention] As detailed above, according to the present invention, it is possible to easily determine whether a vehicle passing on a toll road is a vehicle equipped with an on-vehicle device, and it is normally possible to determine whether a vehicle passing on a toll road is a vehicle equipped with an on-board device or not. Collect tolls for
By transmitting vehicle type information to the on-vehicle device at a predetermined timing, it is possible for vehicles equipped with the vehicle to drive at toll gates without stopping. Toll collection equipment can be provided.
