Description

Description: BACKGROUND OF THE INVENTION The present invention relates to a wireless transmission / reception system for toll roads, a vehicle separation system, and an information processing method. The present invention relates to a system and information processing based on the identification of a vehicle suitable for collection by a vehicle.

[Conventional technology]

Toll roads, such as expressways and motorways, are provided with toll gates, and vehicles traveling on the toll road stop at the gate and pay a toll. For this reason, gates on each toll road are bottlenecks in traffic congestion. Therefore, as a system capable of collecting a toll without cash without stopping the vehicle at a gate, a system using radio waves or using a bar code for vehicle identification has been proposed. It should be noted that a system described in Japanese Patent Application Laid-Open No. 61-9783 is an example of this type of system.

[Problems to be solved by the invention]

However, when using radio waves for vehicle identification, it is possible to transmit radio waves from a running 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 assign individual frequencies to vehicles, and if the same frequency is used, interference may occur between vehicles approaching each other and the vehicle may not be reliably identified. On the other hand, when 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, and the barcode and the detector cannot be identified. The relative positional relationship is restricted. In addition, it is difficult to regulate the location where the barcode is attached to a vehicle having a variety of sizes and shapes like a vehicle, and it is also difficult to communicate between the vehicle and the ground-side treatment device.

SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicle toll collection system capable of reliably identifying a vehicle and collecting a toll without stopping the vehicle at a gate.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a transmitter mounted on a vehicle and transmitting vehicle-specific vehicle information radially in a certain direction outside the vehicle by electromagnetic waves having a frequency of microwaves or more, and traveling on a toll road. A receiver with a protective cover that is installed on the road surface and receives electromagnetic waves from a transmitter mounted on the vehicle passing through the road surface, and the opening of the protective cover of the receiver with the protective cover is the transmission of the vehicle. The installation position of the receiver with the protective cover is located opposite to the device, and the length of the effective reception band determined from the distance between the transmitter and the receiver and the radiation angle of the transmitted electromagnetic wave is the same as that of the preset vehicle. This is a wireless transmission / reception system for a toll road which is set to satisfy a condition that the vehicle pitch is shorter than the minimum vehicle pitch.

In addition, the present invention is mounted on a vehicle, a transmitter that transmits vehicle-specific vehicle information to the upper outside of the vehicle by an electromagnetic wave having a frequency of microwave or more, and a road surface in front of a toll gate entrance is divided into a plurality of zones. A receiver is installed above the road surface on the vehicle entry side of the zone, facing the transmitter so as to receive electromagnetic waves from a transmitter mounted on a vehicle passing on the road surface, and vehicle information received by each receiver. To the information processing device to determine whether the contract information, deposit information, or personal information about the vehicle satisfies the preset conditions, and stores the result in the information processing device. When the receiver receives the vehicle information on the vehicle, the output of the determination result in the processing device is displayed on a display device installed above the road surface of the zone, and from this display result, the vehicle proceeds to the non-stop gate. or It is obtained by constituting the vehicle of the separation system to instruct the progression to tolling gate.

Furthermore, the present invention relates to the vehicle based on the unique information wirelessly transmitted from the vehicle running on the toll road,
When confirming the suitability of multiple items, the driving road surface in front of the toll gate entrance side is divided into multiple zones according to the number of judgment items, and receivers are arranged on the road surface on the vehicle entry side of each zone, Upon receiving the unique information of the vehicle that has entered the zone, based on the unique information, while the vehicle is traveling in the zone, items to be confirmed in the zone in advance, that is, contract information or deposits The information or one of the personal confirmation information is extracted from the information processing device, and it is determined whether or not the information satisfies a preset condition, and the result is transmitted to the information processing device. When stored, when the vehicle enters the next zone, based on the reception of the vehicle information by the receiver, the determination result in the previous zone is extracted from the information processing device and output,
At the same time as transmitting the information to the vehicle, information processing of items to be confirmed in the same zone is performed based on the vehicle information, and the unique information of the vehicle is received by the number of confirmation items so that the result is stored in the information processing device. And an information processing method of repeatedly performing information processing and output of a result based on the received signal.

[Action]

When exchanging information between the vehicle and the ground-side device, the traveling vehicle transmits vehicle-specific vehicle information to the outside of the vehicle by electromagnetic waves having a frequency of microwaves or more, and a receiver installed above the traveling road surface. Although the vehicle information is received from the transmitter, the transmitter and the receiver meet the specified conditions and avoid interference even at the same frequency. It is possible to reliably identify each vehicle even when the other vehicle runs. In other words, when electromagnetic waves having a frequency of microwaves or higher are used as the communication medium, straightness similar to that of light can be obtained, and shielding by obstacles can be easily performed. Even if the approach distance is set to a minimum, a signal from the vehicle can be received and identified without interference if the approach distance is not less than the minimum.

Based on the received vehicle information, when the processing device obtains a positive determination result, the vehicle is instructed to proceed to the non-stop gate, otherwise the vehicle is forced to proceed to the toll collection gate. Vehicles that can collect tolls without cash before passing through can be separated from vehicles that need to collect tolls with cash, making it possible to run smoothly on vehicles that can collect tolls without cash Becomes Further, the result of determining whether or not the vehicle passing through the gate can be deducted from the designated deposit account is displayed on the display device, so that the driver can confirm the result of the fee collection.

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

FIG. 3 shows a basic configuration when an infrared ray having a wavelength of about 940 mm is used as an electromagnetic wave.

As shown in FIG. 3, each vehicle is equipped with a transmitter 90 that transmits vehicle information unique to the vehicle to the outside of the vehicle using infrared rays as a medium. The transmitter 90 includes a light emitting diode 92, a driver circuit 94, a numeric keypad 96, a push button 98, and a number storage unit 1.
00, comprising a reading unit 102, a transmission unit 104, and a control unit 106, and transmits vehicle information as a pulse signal from a light emitting diode. The semiconductor memory of the number storage unit 100 stores a contract number. When setting the contract number, the contract number is assigned one-to-one in association with each vehicle number. In this case, the current vehicle number system is composed of a total of 10 digits including a prefecture code of 2 digits, a vehicle type code of 2 digits, a hiragana of 2 digits, and a consistent number of 4 digits. Therefore, the number of actual vehicles is small.
Therefore, for practical purposes, if the nationwide population is 130 million and half of them can be contracted, the number of contracts N is N = 6.5
× a 10 ⁷ = 2 ^26. Therefore, when a contract number is set for each vehicle, the host computer 80 sets N =
By preparing ²⁶ -number numbers, it will be possible to identify the contract numbers of all vehicles. Usually, the above-mentioned contract number is continuously transmitted from the transmitter 90 as vehicle information unique to the vehicle.

Next, as shown in Figure 6 through Figure 8, to set the lowest vehicle distance and lm, and ₀ to radiation each α of the electromagnetic wave transmitted from each vehicle, the distance from the transmitter 90 to the receiver 16 to 42 Is h, when two vehicles M ₁ and M ₂ emit infrared light,
For while no interference reaching each receiver, the effective receiving zone length infrared at each receiver position (range of extension of the infrared) When l _0, if satisfied lm> l _0, other vehicles Interference of infrared rays from the camera can be prevented. That is, interference can be prevented if the following equation (1) is satisfied.

In order to lengthen the reception time from the vehicles M ₁ and M ₂ , it is advantageous that the effective reception band length l ₀ be as long as possible without causing interference.

Further, it is natural that the relationship of the above formula (1) can be applied to a case where an electromagnetic wave is transmitted to a transmitter or a vehicle on the ground.

For example, the distance between vehicles is lm = 4m, the radiation angle α ₀ = 40 degrees,
When h = 5m, effective reception zone length l ₀ will be 3.64m. In this case, lm> l ₀ holds. On the other hand, if the speed of the vehicle is 60 km / h, the effective reception time under this condition is 16.7 m / s, which is 3.64 m / 16.7 m / s = 0.217 seconds (217 ms), and the maximum transmission time is 192 ms shown below. In this case, such information can be reliably received. For example, a light emitting diode having a “0” pulse interval of 1 ms and a “1” pulse interval of 2 ms has been put to practical use. Therefore, if all the 26-digit numbers of the contract number shown in binary system are formed by “1”, 26 pulses × 2 ms = 5 to transmit 26 pulses
It takes 2ms. Actually, in addition to the above data, three pulses are provided as a key code for data identification and classification,
In addition, when three pulses are expected as a margin time, it takes a maximum of 64 ms to transmit one data pulse. Furthermore, when data is read twice as a countermeasure against malfunction, the required transmission time is doubled or tripled, and the maximum time is 192 ms. Therefore, even if the maximum transmission time is 192 ms, if the effective transmission time is secured at 217 ms, the vehicle will pass the gate at 60 km / h
, The information from the vehicle can be reliably received.

When vehicle information is transmitted from the transmitter 90, the information is received by each of the receivers 16 to 42, and the received information is transmitted to the host computer 80 via the terminals 76, 82 and the terminal devices 78, 84. Supplied. The terminal device 78 adds the gate position information to the information from the receivers 16 and 18 and
The terminal device 84 transfers the received information from the receivers 32 and 34 to the host computer 80 with the gate position information added thereto. That is, the terminals 76 and 82 are each configured as an information output device. Further terminal devices
Reference numerals 78 and 84 denote information processing devices having the ability to centrally perform information processing in each gate.

Information (contract number, vehicle number, etc.) from a keyboard 86 is also input to the host computer 80 via the terminal device 88. Various types of input information are provided as shown in FIG. adapted to be stored according to the record R ₁ in the memory. Record R ₁ has fields F _{1 to} F ₉
Is divided into, contract number field F _1, the vehicle number in F _2, PIN to F _3, the personal information in the field F ₄ (deposit account, name, etc. information), the field F ₅ is deposit balances, the field F ₆ entrance gate number, exit gate number in the field F _7, rates are in the field F _8, field
The F ₉ information such as the determination result is adapted to be stored. Then, with the support of the host computer 80, the terminal devices 78 and 84 extract the deposit information of the vehicle passing through the entrance gate 12 and the exit gate 14 from the processing information group, and pass through the gate. It is configured as a processing device that calculates a vehicle fee, determines whether the calculated fee can be deducted from a specified deposit account, and executes a process according to the determination result. The processing results of the terminal devices 78 and 84 are displayed on the display devices 44, 46, 48, 50, 52,
It is displayed on 54,56,58.

In the above arrangement, when the vehicle is traveling along the traveling lane L ₁ passes through the query zone Z _1, the from the transmitter 90 transmits the vehicle information, but is received by the receiver 16 or 18, in FIG. 9 The signal processing diagram is shown. First, information from the transmitter 90 is received by the receiver 16, and the received information is transferred to the host computer 80. Then, query the pre-stored contract number to the vehicle information and the host computer 80 that the transfer is done, the query result is the contents of a record R ₁ related contract number from the host computer 80 only if an OK terminal device 78 Transfer to The terminal device 78 inquires the deposit balance of the vehicle based on the input information, and outputs a determination result of OK if the deposit balance of the vehicle is equal to or more than a value necessary for traveling on the toll road. In such a case, the result of the NG determination is output. Then the vehicle enters the zone Z ₁ to the zone Z ₂ when the vehicle information receiver from the vehicle 20
Received by FIG. 10 shows the signal processing diagram. Vehicle information received by the receiver 20 is already OK on the terminal device 78
In the case of the vehicle determined to be, the lower four digits of the compatible vehicle are displayed on the display device 44 as shown in FIG. 11 as a vehicle (compatible vehicle) capable of running without cash. You. FIG. 11 is an example in which vehicle numbers are displayed in two rows, upper and lower, respectively. Vehicles vehicle number is displayed on the display device 44 is instructed progression to the running lane L ₄ as compliant vehicles, whereas panel

That is, the conforming vehicle is instructed to proceed to the non-stop entrance gate, and the non-conforming vehicle is forced to proceed to the toll collection gate.

Next, when the vehicle enters the zone Z ₄ by traveling along the traveling lane L _4, information from the vehicle is received by the receiver 24,
As shown in FIG. 12, when an inquiry is made to the terminal device 78 as to whether or not the vehicle is a compatible vehicle based on the vehicle information of the vehicle and the inquiry result is determined to be a compatible vehicle, the display shown in FIG. The vehicle number is displayed on the device 46. Also, the display device 46 displays “Password is issued”. At this time, the driver presses the push button 98
Is operated to transmit the password, the receiver 24 receives the same signal and inquires the terminal device 78 of the password.
When the inquiry result is OK, the character of OK is displayed on the display device 46, and when the inquiry result is NG, the character of NG is displayed.
The information on these discrimination results and entrance gate number is transmitted to the host computer 80, information of the gate number of the inlet gate 12 is stored in the field F ₆ records R ₁ corresponding to the contract number and vehicle number.

Then, the vehicle enters the query zone Z ₇ of the traveling lane L ₇ travels toward the exit gate 14, as shown in FIG. 14, the transmission information from the vehicle is received by the receiver 32 Then, the received information is transferred to the host computer 80. Thus the contents of the record R ₁ in accordance with the contract number of the vehicle is transferred to the terminal device 84, the determination result of the query of the vehicle is adapted vehicles whether determination result and the personal identification number is performed. If the inquiry result is OK, the toll for the vehicle is calculated from the entrance gate number and the exit gate number for the vehicle, and it is determined whether or not this fee can be deducted from the designated deposit account. A determination is made. If the judgment result is OK, the fee is deducted from the specified account, the judgment result is output as OK, otherwise the judgment result is
Output as NG. After this process is completed, when the vehicle enters the zone Z _8, as shown in FIG. 15, the transmission information from the vehicle is received by the receiver 36, the car has become possible to collect the fee ( An inquiry is made to the terminal device 84 as to whether the vehicle is a contracted vehicle). Then, when the inquiry result to the terminal device 84 is OK, as shown in FIG.
Will be displayed. FIG. 16 shows an example in which the information is displayed in two columns.
And for the contract conclusion vehicle is instructed progression to the running lane L _10, progression to traveling lane L ₉ in the other vehicle is forced. Incidentally, the travel progress of the lanes L ₈ against vehicles traveling to the traveling lane L ₁₂ in the case of contract formation vehicle is indicated and in the other vehicle is forced progression to the running lane L _11. Thus separation of the contract formation vehicles and other vehicles in the zone Z ₉ is performed.

Next, when the vehicle running lane L ₁₀ enters the zone Z _10, as shown in FIG. 17, the transmission information from the vehicle is received by the receiver 40, the vehicle from received information contract formation An inquiry as to whether the vehicle is a car is made to the terminal device 84. If the result of the inquiry to the terminal device 84 is OK, the vehicle number and the toll of the vehicle are displayed on the display device 56, and the processing result, the information about the toll and the exit gate number are transferred to the host computer 80, and the inquiry is made. Processing according to the result is performed. That is, the toll is deducted from the designated deposit account.

On the other hand, if the inquiry result of the contracted car is NG,
When the vehicle passes through the exit gate 14, the photographing device 72 operates to photograph the vehicle, and the inquiry result NG
And the fee and the exit gate number are transferred to the host computer 80.

Here, when operating the imaging device 72, when the vehicle travels through the zone Z _11, detects the order in which the light has been received by each light receiver 78 and 86 from each emitter 76 and 84, received the order Since it is possible to match the order of the vehicle received by the receiver 40 with whether or not the vehicle is a contracted vehicle, if the photographing device 72 is operated in accordance with the sequence, it is possible to surely photograph the vehicle whose contract has not been established. it can. That is, the vehicle enters the zone Z ₁₁ based on the input information signal from the light receiver 78 and 86 from the receiver 40, can perform determination of whether or not the contract established vehicle in accordance with the order. Vehicle contract conclusion vehicle and unsatisfied vehicle by the determination result is in the zone Z _11.
Therefore, according to the operation of the light receiver 86 and the above determination result,
