Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a toll road wireless transmission/reception system, a vehicle separation system, and an information processing method, and in particular, to a cashless method for paying tolls for vehicles traveling on toll roads. The present invention relates to a system and information processing based on the identification and identification of vehicles suitable for collection.

[Conventional technology]

Toll roads such as expressways and expressways are equipped with gates for toll collection, and vehicles traveling on the toll roads must temporarily stop at the gate and pay the toll. For this reason, the gates of each toll road have become bottlenecks in traffic congestion. Therefore, systems that use radio waves or barcodes to identify vehicles have been proposed as systems that can collect tolls in a cashless manner without having to stop the vehicle at a gate. An example of this type of system is the one described in Japanese Unexamined Patent Publication No. 61-9783.

[Problem to be solved by the invention]

However, when using radio waves to identify vehicles, it is possible to transmit radio waves from a moving vehicle and analyze the content of the radio waves with a processing device installed at the gate to identify the vehicle. It is impossible to allocate individual frequencies to vehicles, and if the same frequency is used, there is a risk that vehicles that are close to each other will interfere with each other, making it impossible to reliably identify the vehicles. - On the other hand, if the barcode method is applied, the vehicle cannot be reliably identified unless the positional relationship between the barcode attached to the vehicle and the detector installed at the gate is constant. The relative positional relationship of is constrained. Furthermore, it is difficult to restrict the location of barcodes on objects of various sizes and shapes, such as vehicles, and mutual communication between vehicles and ground-side treatment devices is also difficult.

An object of the present invention is to provide a toll collection system for vehicles that can reliably identify vehicles and collect tolls without stopping the vehicle at a gate.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a transmitter that is mounted on a vehicle and transmits vehicle information unique to the vehicle radially in a certain direction outside the vehicle using electromagnetic waves with a frequency higher than microwaves, and It has a hooded receiver that is installed on the road surface and receives electromagnetic waves from a transmitter mounted on a vehicle passing on the road surface, and the opening of the hood of the hooded receiver faces the vehicle's transmitter. The installation position of the hooded receiver is such that the length of the effective reception band, determined from the distance between the transmitter and receiver and the radiation angle of the electromagnetic waves to be transmitted, is longer than the preset minimum vehicle pitch between vehicles. This is a wireless transmission/reception system for toll roads that is set to meet the conditions for shorter toll roads.

a transmitter that is mounted on a vehicle and transmits vehicle-specific vehicle information upwardly outside the vehicle using electromagnetic waves with a frequency higher than microwave;
The driving road surface in front of the toll gate entrance is divided into multiple zones, and a transmitter is placed above the road surface on the vehicle entry side of each zone to receive electromagnetic waves from a transmitter mounted on a vehicle passing on this road surface. The vehicle information received by each receiver is sent to an information processing device to determine whether the contract information, deposit information, or personal information regarding the vehicle satisfies preset conditions. The results are stored in the information processing device, and when the receiver in the next zone receives vehicle information regarding the vehicle, the output of the determination result in the processing device is installed above the road surface in the zone. This is a vehicle separation system that displays on a display device and instructs the vehicle to proceed to the non-stop gate or to the toll collection gate based on the displayed result.

When confirming the suitability of multiple items regarding a vehicle based on unique information transmitted by radio from a vehicle traveling on a toll road, the road surface in front of the toll gate entrance is checked according to the number of judgment items. The system is divided into multiple zones, and a receiver is placed on the road surface on the vehicle intrusion side of each zone to receive the unique information of the vehicle that has invaded the zone, and based on the unique information, the corresponding vehicle
While driving in the zone, one of the items to be confirmed in the zone in advance, such as contract information, deposit information, or personal verification information, is extracted from the information processing device,
It is determined whether this information satisfies preset conditions, the results are stored in the information processing device, and when the vehicle enters the next zone, the receiver Based on the reception of the vehicle information, the judgment result that can be placed in the previous zone is retrieved from the information processing device and output, and transmitted to the vehicle, and at the same time, information processing of items to be confirmed in the same zone is performed based on the vehicle information. An information processing method is configured in which vehicle specific information is received as many times as there are confirmation items, and the information processing and result output are repeatedly performed based on the received signals, such that the results are stored in the information processing device. It is.

[Effect]

When exchanging information between a vehicle and a ground-side device, vehicle information unique to the vehicle is transmitted upwards outside the vehicle using electromagnetic waves with a frequency higher than microwaves, and is transmitted by a receiver installed above the road surface. Vehicle information is received from the transmitter, but certain conditions are satisfied between the transmitter and receiver to prevent interference even on the same frequency, so multiple vehicles can be connected to the same driving road surface. Even when several vehicles are running, each vehicle can be reliably identified.

In other words, when electromagnetic waves with a frequency higher than microwaves are used as a communication medium, they can travel in a straight line similar to light, and can be easily blocked by obstacles, so multiple vehicles approaching each other can transmit signals of the same frequency. However, if a minimum approach distance is set, and the vehicle does not approach below the minimum distance, signals from the vehicle can be received and identified without interference.

Based on the received vehicle information, when a positive determination result is obtained by the processing device, the vehicle is instructed to proceed to the non-stop gate, and in other cases, the vehicle is forced to proceed to the toll collection gate.

It is possible to separate vehicles that can collect tolls cashlessly from those that need to collect tolls in cash before passing through the gate, making it possible to smoothly run vehicles that can collect tolls cashlessly. It becomes possible. Furthermore, the display device displays the determination result as to whether or not the toll can be debited from the designated deposit account for the vehicle passing through the gate, allowing the driver to confirm the toll collection result.

The host computer 80 is provided with the field shown in FIG. 4 and a key code for specifying the inside of the field, so that when data is transmitted or received based on vehicle information, the contents of the field can be identified from the key code.

Figure 3 shows the basic configuration when infrared rays with a wavelength of approximately 940 mm are used as electromagnetic waves.

As shown in FIG. 3, each vehicle is equipped with a transmitter 90 that transmits vehicle information specific to the vehicle upwardly outside the vehicle using infrared rays as a medium. The transmitter 90 includes a light emitting diode 92. Driver circuit 94. Numeric keypad 96. bush button 98
2 number storage unit 100° reading unit 102. Transmission section 104
．． A contract number is stored in a semiconductor memory of a 9 number storage section 100, which is composed of a control section 106 and transmits vehicle information as a pulse signal from one light emitting diode. When setting contract numbers, assign them one-to-one in association with each vehicle number. In this case, the current vehicle number system consists of a total of 10 digits: 2 digits for the prefecture code, 2 digits for the vehicle model code, 2 digits for hiragana, and 4 digits for the serial number, but this includes missing numbers. Because of this, the actual number of cars is small. So, in practical terms,
Assuming that the population of the country is 130 million people and that half of them can contract, the number of contracts N is N = 6.5 x 10' = 21. Therefore, when a contract number is set for each vehicle, the host computer 8o has N = 2 Z as a contract number.
If six scale numbers are prepared, it will be possible to identify the contract numbers of all vehicles. Normally, the transmitter 90 continuously transmits the aforementioned contract number as vehicle information unique to the vehicle.

Next, as shown in FIGS. 6 to 8, the minimum vehicle interval is set as Qm, and the electromagnetic wave radiation transmitted from each vehicle is α. Assuming that the distance from the transmitter 90 to the receivers 16 to 42 is h, when infrared rays are emitted from two vehicle mechanics 5M2, in order to reach each receiver without interference, each receiver must be If the effective reception length of infrared rays (the range in which infrared rays spread) at a position is Q+, then Qm>α. If this is true, infrared interference from other vehicles can be prevented.

That is, if the following equation (1) holds true, interference can be prevented.

11m>Q. =2tan-Xh-(1)
In order to extend the reception time of the vehicle mechanics 9M2, it is advantageous to make the effective reception length 42o as long as possible without causing interference.

Furthermore, it goes without saying that the relationship in equation (1) above can also be applied to the case where electromagnetic waves are transmitted to a transmitter on the ground or a vehicle.

As an example, the distance between vehicles is nm = 4 m, and the radiation angle is α. =40
If h = 5 m, the effective receiving cloth length Q is 3.64 m.
becomes. In this case, Qm>Q holds true. On the other hand, if the speed of the vehicle is 60 km/h, it is converted to 16.7 m/s per second.
Therefore, the effective reception time under this condition is 3.64 m/16.7 m/s = 0.217 seconds (217 m/s).
m5), and even if the maximum transmission time is 192 m5 as shown below, these pieces of information can be reliably received.

For example, set the It 017 pulse interval of the light emitting diode to 1
ms binding l(l'' pulse interval is 2 ms) has been put into practical use.
If all digit numbers are formed with #I II, in order to transmit 26 pulses, 26 digits x 2m5 = 52n+
It takes s time. Actually, in addition to the above data, three pulses are provided as a key code for data identification and classification, and if three pulses are allowed as a margin time, it takes a maximum of 64 m5 to transmit one data pulse. Furthermore, if data is read twice as a countermeasure against malfunctions, the required transmission time will be doubled or tripled, and the maximum time will be 192+n.
It becomes s. Therefore, even if the maximum transmission time is 192 [118], if the effective transmission time is 217+++s, information from the vehicle can be reliably received even if the vehicle passes through the gate at 60 km/h.

Further, when vehicle information is transmitted from the transmitter 90, this information is received by each of the receivers 16 to 42, and the received information is sent to the host computer 80 via the terminal 76.82 and the terminal equipment 1178.84. Supplied. Terminal device 7
8 attaches gate position information to the information from the receivers 16 and 18 and transfers it to the host computer 80, and the terminal device 84 attaches gate position information to the information received from the receivers 32 and 34 and sends it to the host computer 80. It is designed to be transferred. That is, the terminals 76, 82 are each configured as an information output device. Further, the terminal devices 78 and 84 are information processing devices having the ability to intensively perform information processing within each gate.

Information from the keyboard 86 (information such as contract number, vehicle number, etc.) is also input to the host computer 80 via a terminal device 88, and various input information is inputted as shown in FIG. , the records are stored in memory according to the R process. Record R1 is divided into fields F□ to F, field F is the contract number, F2 is the vehicle number, F is the PIN number, and field F4 is personal information (information such as the name of deposit account 2). ), field F5 stores the deposit balance, field F stores the entrance gate number, field F7 stores the exit gate number, field F stores the fee, and field Fg stores the determination result. There is.

And the terminal devices 78, 84 . is host computer 8
With the support of 0, entrance gate 12, exit gate 14
Extracts the deposit information of the vehicle passing through the gate from the processing information group, calculates the fee for the vehicle to pass through the gate, determines whether the calculated fee can be debited from the specified deposit account, and makes a judgment. It is configured as a processing device that executes processing according to the results. The processing results of the terminal device 78.84 are displayed on the display device 4 via the terminal 76.82.
4, 46, 48, 50, 52, 54, 56°58.

In the above configuration, when a vehicle traveling in driving lane L□ passes through inquiry zone Z, vehicle information is transmitted from transmitter 90 and is received by receiver 16 or 18. A signal processing diagram is shown. Information from transmitter 90 is first received by receiver 16, and this received information is forwarded to host computer 80. Then, an inquiry is made between the transferred vehicle information and the contract number stored in advance in the host computer 80, and only when the inquiry result is OK, the content of the record R1 regarding the contract number is sent from the host computer 80 to the terminal device 78. Forward. The terminal device 78 inquires about the deposit balance of the vehicle based on the input information, and outputs an OK determination result if the deposit balance of the vehicle is equal to or greater than the value necessary for driving on the toll road.
In other cases, an NG determination result is output. Next, when a vehicle enters zone Z2 from zone Z1, vehicle information from the vehicle is received by receiver 20. FIG. 10 shows the signal processing diagram. In the case of a vehicle whose vehicle information received by the receiver 20 has already been determined to be OK by the terminal device 78, the last four digits of the vehicle number of the conforming vehicle are classified as vehicles capable of cashless driving (conforming vehicles). As shown in FIG. 11, it is displayed on the display device 44. 1st
Figure 1 is an example in which vehicle numbers are displayed in two rows, upper and lower. The vehicle whose vehicle number is displayed on the display device 44 is designated as a conforming vehicle and is instructed to proceed to the driving lane L4, while the display board 4
In the case of a non-conforming vehicle whose vehicle number is not displayed in section 4, it is forced to proceed to driving lane L3, and the vehicles are separated in separation zone Z. In other words, compliant vehicles are instructed to proceed to the non-stop entrance gate, and non-compliant vehicles are forced to proceed to the toll collection entrance gate.

Next, the vehicle travels in driving lane L4 and enters zone Z.

When the vehicle enters the vehicle, information from the vehicle is received by the receiver 24, and as shown in FIG. When the inquiry result is determined to be a conforming vehicle,
The vehicle number is displayed on the display device 46 in FIG. Further, the display device 46 displays “Give me your password”. At this time, when the driver operates push button 98 and sends the PIN number,
The receiver 24 receives the signal and inquires the terminal device 78 about the password. If the inquiry result is OK,
The word OK is displayed on the display device 46, and the inquiry result is NG.
In this case, the word NG is displayed. These determination results and information regarding the entrance gate number are transmitted to the host computer 80, and information about the gate number of the entrance gate 12 is stored in field F6 of the record length corresponding to the contract number and vehicle number.

Next, when the vehicle travels toward the exit gate 14 and enters the inquiry zone Z7 of the travel lane L7, the transmitted information from the vehicle is received by the receiver 32, as shown in FIG. Information is transferred to host computer 80. As a result, the contents of the record length according to the contract number of the vehicle are transferred to the terminal device 84, and the determination result of whether the vehicle is a conforming vehicle and the determination result of the password are inquired. And if the inquiry result is OK.

The toll fee for the vehicle is calculated from the entrance gate number of the vehicle and the gate number of the exit gate 4, and it is determined whether this fee can be debited from the specified deposit account. If the determination result is OK, the fee is debited from the specified account and the determination result is output as OK; otherwise, the determination result is output as NG. After this process is completed, when the vehicle enters zone Z8,
As shown in FIG. 15, the transmitted information from the vehicle is received by the receiver 36, and an inquiry is made to the terminal device 84 as to whether or not the vehicle is a vehicle for which tolls can be collected (contract established). It is done. When the inquiry result to the terminal device 84 is OK, the last four digits of the vehicle number of the contracted vehicle are displayed on the display device 54, as shown in FIG. FIG. 16 is an example of display in two levels, upper and lower. And for the bundle of contracts, there is a driving lane Li. The other vehicles are forced to proceed to driving lane Lg. It should be noted that if a contract is established for a vehicle traveling in driving lane L, it is instructed to proceed to driving lane L1□, and other vehicles are forced to proceed to driving lane L1□.

As a result, contract vehicles are separated from other vehicles in zone Z9.

Next, driving lane L□. Vehicles traveling in this area are Zone Z construction vehicles.

Once entered, as shown in FIG. 17, the transmission information from the vehicle is received by the receiver 140, and an inquiry is made to the terminal bag M84 from the received information as to whether or not the vehicle is under contract. If the inquiry result to the terminal device 84 is OK, the vehicle number and toll of the vehicle in question are displayed on the display device 56, and the processing result, information regarding the toll and exit gate number are transferred to the host computer 80, and the inquiry is made. Processing is performed according to the results. In other words, the toll fee is deducted from the specified deposit account.

On the other hand, if the inquiry result of contract conclusion is NG,
When the vehicle passes through the exit gate 14, the photographing device 7
2 is activated to take a photograph of the vehicle, and the inquiry result No., fare, and exit gate number are transferred to the host computer 80.

Here, when operating the photographic bag M72, when the vehicle travels in the zone Z11, the order in which each light receiver 78.86 receives light from each light projector 76.84 is detected,
Since the order in which the light is received can match the order in which the vehicles received by the receiver 40 are determined to be vehicles with which a contract has been concluded, if the photographing device 72 is operated in accordance with that order, it is possible to ensure the photographing of vehicles with which a contract has not been concluded. can be done. That is, the information input from the receiver 40 and the light receiver 78°86
Based on the signals from the zone z1□, it can be determined whether or not a vehicle enters the zone z1□, according to the order in which the contract is concluded. As a result of this determination, the vehicles with which the contract has been established and those with which the contract has not been established are located within the zone Z11.

Therefore, by operating the photographing device 72 in accordance with the operation of the light receiver 86 and the above-mentioned determination result, it is possible to reliably photograph the vehicle for which the contract has not been concluded.

As described above, in this embodiment, among the vehicles traveling on the toll road 10, the vehicles that are instructed to travel to the driving lanes L, L6 are not allowed to enter the toll road 10 without stopping at the entrance gate 12. is possible, and driving lanes L1゜, L
Vehicles that have been instructed to proceed to 1□ can exit toll road 10 without stopping at exit gate 14, and can prevent traffic jams at gates 12 and 14 on toll road 0. .

Note that at the entrance gate 12, the driving lane L3. L
Vehicles forced to proceed to s are manned tollgates 60.6
2, a card regarding the entrance gate 12 is handed over,
In addition, at the exit gate 14, the driving lane LgHL11
Vehicles forced to proceed to the exit gate 4 temporarily stop at the exit gate 4, and a toll is collected based on the card handed over at the entrance gate 12.
